I. The Mind
A. Definition: An active system or organization of
cognitive, conative, and affective meanings or understandings, along with
procedures for implementing and changing these meanings.
e. Problem
solving: A cognitive process
because it involves implementing meanings.
‘Judgments’, ‘Decisions’, ‘Inferences” are also procedures for
implementing meanings
C. Mind and Body (Brain)
1. Dualism.
2. Monism – Reductionistic (‘nothing
but’) & Non-Reductionistic.
D. Mind and Consciousness
1. Consciousness = Awareness. This is the fundamental characteristic of
Mind.
2. Levels of consciousness.
a. There can be multiple levels of consciousness ranging from the ‘basic’ awareness that non-human animals and infant humans exhibit, to the highly reflective symbolic awareness. The text does not mention levels and the discussion in the text tends to focus on what we will call 'extended consciousness.'
1.)
The basic level is sometimes called ‘core consciousness’ and it has the
following characteristics: Wakefulness,
Attention to presented stimuli, Attention can be focused and sustained over
periods of time, Background emotions flow continuously, Spontaneous behavior is
purposeful (see Antonio Demasio).
2.)
Higher levels of emotion are sometimes called ‘extended consciousness. This involves a sense of self and a sense of
objects and a sense of the relationship between the two.
b.
Each higher level of extended consciousness is defined by the ability to
reflect on each of the lower levels. (For example, you can think about yourself
talking to someone else; but an infant can’t do this)
c.
Each of the higher levels of consciousness is the outcome of the process
of development to be discussed next.
2. The Unconscious
a. As special mental process (Freud)
b. As nonconscious
E. Functions of the Mind and Consciousness.
1. Mediate between body and world. Thus at extended levels it a) Monitors the self and the environment and b) Controls cognition and behavior (see p. 394 of text)

Chapter 8, pp. 375-382. Nature and Nurture
I. The Nature of Development.
A. Development is about change. Change involves orderly sequence. So Development is defined as relatively
permanent change that moves towards some final state or final system.
e.g., Final state of a
flying machine. Here have changes that
led to the modern jet airplane. That’s
development of the airplane.
e.g., Current organization or
system called “human beings.” Here have
phylogenetic changes that have led to modern man. Phylogenetic development.
B. Developmental Psychology is about
change of Psyche (i.e., mind and consciousness) and about changes of
behavior. These changes can occur
across the life span from the time the egg is fertilized (prenatal
development) through infancy, toddlerhood, childhood, adolescence, adulthood,
and the elderly years.
e.g., Piaget’s theory focuses on the development of the cognitive dimension of mind from infancy through adolescence. The final organization here is the way normal mature adults are able to think about their thinking, and make judgments and evaluations about their thinking and about their behavior.
e.g., Erikson’s theory focuses on
the development of the affective and motivational dimensions of mind, from
infancy through the late elderly years.
The final organization here is the way normal mature adults integrate
feelings and desires into an adapted whole personality.
e.g., There are theories of the
development of memory. Here, the final
organization is the way normal mature adults are able to recall and recognize
earlier experienced events.
e.g., There are theories of the
development of walking. Here, the final
organization is the way normal 4 year olds walk.
e.g., There are theories of the
development of language. Here, the final
organization is the way normal adults understand and produce language.
e.g., There are theories of the
development of the embryo (embryogenesis).
Here, the final organization is the newborn.
II. Two Types of Developmental Change.
A. Transformational Change: This is the case where the form or organization of the
thing (e.g., mind, consciousness, cognition, feelings, behavior) changes
into another form or another organization.
e.g., The caterpillar develops
(becomes transformed into) the butterfly.
e.g., Hydrogen and Oxygen develop into Water.
e.g., Water becomes transformed into ice, and water becomes transformed into steam.
e.g., The core consciousness of the infant becomes
transformed into thinking and the extended consciousness of the toddler and
this becomes transformed into the reflective thought of the child.
e.g., The crawling of the infant becomes
transformed into the walking of the child.
1. Transformational change involves the emergence
of novelty (the new). When a
form changes sufficiently, something new emerges that was not there before.
e.g., Water is a novel system that emerges from Hydrogen and Oxygen. Water has characteristics (e.g., wet, taste) that is not found in either of its constituent parts.
e.g.,
Walking is something new and, in fact, it does not use the same muscle systems
that crawling used.
e.g.,
Thinking arises out of the core consciousness of early infancy, but it is
something different in organization then that core consciousness. The newborn does not have thoughts or
thinking. Thinking is a novel system
that emerges from action when the mind has gone through several transformations
2. This novelty is often discussed as ‘qualitative
changes in complexity’.
3. When transformational change occurs the
novel result or qualitative change is often referred to as being a ‘discontinuity’
of development and it is marked by being called a new ‘stage’ or new ‘level
of organization’ (both mean the same).
4. Piaget’s theory and Erikson’s theory, for
example, focus on transformational change and they describe development in
terms of stages. Each stage marks a
novel qualitative change.
B. Variational Change. This is the case where something (e.g., behavior) varies around
some norm or average.
e.g., The pecking behavior of the pigeon. The pigeon pecks here and there, slower and faster. The change in where, when, and how fast, are all variational changes.
e.g.,
The child’s reaching behavior as in reaching for a toy. In early infancy at first get wide sweeps
with whole body, later get more precise movements.
e.g.,
Child getting more and more precise at walking, after the novelty has occurred.
e.g., Person who gets better and better on an
exam.
1. Variational change is about a skill or
ability becoming more precise and more accurate.
2. Nothing new emerges with respect to
variational change and so it is called ‘quantitative’ or ‘additive’ change
in complexity.
3. Because nothing new emerges in variational
change, the quantitative change is often referred to as the ‘continuity’
of development.
4. Because nothing new emerges in variational
change, people who study variational development rarely ever describe
development in terms of stages. In
variational development the child is described as getting closer and closer to
a target behavioral goal. This is
sometimes called ‘adjustment’ and often theories that focus on variational
development explore the ways in which the child’s behavior adjusts to the
demands of the environment.
5. Skinner’s theory is a good example of a
theory that focuses on variational change.
III. Explanation of Development I: Models of the Nature of the Person.
The background presupposition (assumption, model) the scientist has about the nature of persons and their relation to the environment will influence how development is explained. Here are three possible models:
1. The Empiricist Model
Lump
of Matter
Sculpture
Tabula
Rasa (Blank Slate)
Engraver
2. The Nativist Model
Steel
Filing Cabinet
Filing Clerk
3.
The Action Interactionist or Co-action Model
A
Living Plant
Gardener
IV. Explanation of Development II: The Nature—Nurture Controversy.
A.
This is the question of what accounts for or explains development.
B.
Traditionally this has been a clash of:
1. Nature – (i.e. Biology, heredity,
genes, instinct, innate factors). Generally this is the Nativists or Steel
Filing Cabinet Model
versus
2. Nurture – (i.e., Environment,
learning, practice). Generally this is the Empiricists or Lump of Matter, Blank
Slate Model.
C. Classically, and still often in the popular press, characterized as a struggle between two exclusive choices. This is often called the “Which One” question.
e.g., Which one? Nature or nurture causes (explains)
schizophrenia?
e.g.,
Which one? Genes or watching violent TV
caused the killing at Colombine?
e.g., Which one?
Brain factors or parenting style causes sexual identity?
e.g., Which one?
Genes or education causes intelligence?
1. This is a scientifically useless way of
approaching the issue of the explanation of the development of mind or behavior. All of Psyche and behavior represent a
complex and non-separable interweaving of both nature and nurture. Like the ingredients of a cake cannot be
separated out after the baking has occurred.
D. Some have changed the “Which One?” Question
into the “How Much?” Question.
Here people ask how much of any behavior is caused by one and how much
is caused by the other factor.
Sophisticated statistical techniques are used to attempt to measure
this.
1. Although there is a group who use this
approach it too is ultimately an unsuccessful approach to the explanation of
the development of mind or behavior. It
fails to recognize that a gene always acts in the context of an environment and
the coaction of the two transforms the outcome in ways that do not allow for a
meaningful separation. Think of mind
and behavior being like snow. Would you
ever ask how much of snow is caused by water and how much is caused by
temperature? No, that would be a silly
question. We know that snow is 100% due
to water and 100% due to temperature.
Snow is the outcome of the interaction of water and temp. Think of mind and behavior in the same
fashion.
E. The Co-Action or Interaction
Resolution. Understand
development according to the plant model.
Genes are necessary – no matter what environment you have – the plant is
going to be a tomato plant. However,
the timing and characteristics of the environment are just as necessary. The two factors cannot be separated to
answer the Which One? or the How Much? questions. Development is the product of the coaction between nature and
nurture at every level from DNA in relation to its environment, to the genetic
in relation to its environment, to the cell in relation to its environment, to
the embryo in relation to its environment to the infant in relation to its
environment etc. etc.
1. Explore the How? Question. How are specific nature factors and how
are specific environmental factors related to the growth of mind and behavior.
e.g.,
How does a specific chromosome defect (e.g., as in down’s syndrome) relate
to the growth of intelligence. Is it
related to a slowing of development?
e.g.,
How does parenting style relate to the growth of intelligence. Do some styles result in faster development
or slower development?
V. Explanation of Development III: Action and Experience.
A. Given the Co-actionist solution, given the
acceptance of the plant model of person and behavior, the question
remains: What explains the development
of mind and behavior according to the co-actionist position? This is the question of the ‘mechanism’
(explanation) of development.
B. To answer this must first again note that we
are here primarily focused on the development of the person, the development of
Psyche or mind. Thus, our psychology is
going to be primarily a person-centered or organism centered rather than a
biology centered or an environment centered psychology.
C. Given this, the answer about the mechanism
of development is that it is the ACTION of the active organized system
called the person, organism, or mind.
That is, the action of mind is the mechanism of its own change. We will see that this is exactly the
solution of theorists like Piaget and Erikson.
1. Organisms develop through their own action
in the world. As organism is a an
active ‘self-organizing system’
2. The process goes like this:
a. Out of 9 months of coaction
or interaction of BODY (genetics, physiological, neurological) and
ENVIRONMENT, there emerges at birth an integrated set of action systems. These action systems and their interrelation
constitute the initial psychological organism, the basic level of mind, the
level of core consciousness. All action
that is emitted by these action systems is necessarily a reflection of the nature
of the current organization of Psyche.
e.g., The infant is partially a sucking organization – a sucking
action system
e.g., The infant is partially a reaching organization – a
reaching action system.
e.g., The infant is partially a grasping organization – a
grasping action system.
e.g., The infant is partially a looking organization – a looking
action system.
b. Completely successful action
of the system fulfills the need or intention of the system. With success the system is in ‘EQUILIBRIUM’
or balance with the environment. The
system action continues and repeats itself and no change occurs.
c. Total failure of action of
the system leads to system break down (e.g., crying). No change occurs in this situation. System is not in equilibrium but it is so far out of balance that
the system fragments.
d. Partially
successful/partially unsuccessful actions are also out of equilibrium, but variations
in the original behavior brings about success and brings the system into a new
balance.
e.g., the infant sucking action varies (harder and weaker) and this
leads to a better draw on the nipple.
1). Here feedback occurs, and the system itself
changes (transformation) in conformance with that feedback. Here have development and it is explained
by the action of the system.
e.g., grasping varies
and becomes smoother; same with looking; this leads to the two systems becoming
integrated to form the novelty of visually directed looking.
2). Thus, DEVELOPMENT IS ALWAYS THE RESULT
OF ACTION THAT ARISES OUT OF THE ORGANIZATION OF MIND AND RETURNS TO CHANGE THE
ORGANIZATION OF MIND.
D. Action and Experience can be used interchangeably when experience means the action of manipulating, observing, exploring the world. Thus, development occurs through experience.
1. Note this definition of experience is different from one that defines experience as ‘environmental input’. There ‘experience as environmental input simply comes to be a part of ‘nurture’. Here experience as action is both nature and nurture.
E.
Assimilation and Accommodation as two phases
of any action or experience.
1. Will soon discuss Piaget’s theory of
development. Piaget specifically
discusses action as the mechanism of development. Piaget uses the concepts of assimilation and
accommodation to explain development.
2. Assimilation is the phase of action
that applies the current mental organization (Piaget calls the early mental
organization – schemes) to the world.
As your text suggests, assimilation “modifies new environmental
information to fit what is already known.”
For example, the infant will suck almost anything offered. Thus the child turns whatever new is given
to her into a ‘suckable.’ This is
giving meaning to the world in terms of what is already known. (Note the
knowledge here is not reflected knowledge)
3. Accommodation is the phase of action that
restructures or modifies the existing mental organization.
4. Assimilation is the direct application of
mental organization to the world, and accommodation is the variation of action that
occurs if assimilation was not completely successful. Once one of the action variations is successful that becomes a
part of the new mental organization and is used in assimilation.
5. Every act involves both assimilation and
accommodation to some extent.
a.
Successful Behavior: The
system is in equilibrium with its environment.
The organism’s need or intention is met immediately. Here there is much more assimilation than
accommodation.
b.
Very Unsuccessful Behavior:
Disequilibrium. Needs and
intentions not met. Here there is
assimilation and a break down of accommodation.
c.
Partially Unsuccessful Behavior:
Slight disequilibrium. Some work
occurs on the way to success. Here
there is assimilation but when this doesn’t work completely there is more
variation in the behavior and this then leads to a change in the mental
organization – accommodation.
d.
As another famous psychologist once said: “Assimilate when you can,
accommodate when you must.”
6. Development consists of the phases of action
moving toward a balance called equilibrium and towards ever more
adaptive forms of equilibrium, called the equilibration process.
a.
The kind of equilibrium discussed earlier is a balance
between the organism and the environment.
b.
Second kind of equilibrium is the balance between
assimilation and accommodation that is available to the organism.
1). At the beginning of each major stage of
mental organization there is a lack of balance. At the beginning of any stage the phase of assimilation is
dominant and there is very little variation possible in the action (i.e.,
little accommodation). Thus, any stage
involves a movement towards a balance or equilibrium between assimilation and
accommodation.
e.g., Newborn has only one way of grasping an
object (assimilation) there is virtually no variation (accommodation) in this
act. However, by the time the infant is
1 year she can grasp (assimilate) objects in many different ways (accommodate). Can grasp with the whole hand, with two
hands, with two fingers, with feet etc.
So at 1 year there is a balance between the assimilation (grasping) and
the way the grasping can be done (accommodation).
2.) At the end of any stage there is an
equilibrium but the cognitive reorganization that occurs in the movement to the
next stage results in a new disequilibrium and the process has to be repeated
again at a new level of consciousness.
The progressive movement towards increasingly flexible and adaptive
forms of assimilation/accommodation equilibrium is called the equilibration
process.
e.g., The best of Logical thinking (concrete operational thinking) is a more adaptive than the best thinking that has no possibility of logic to it (pre-operational thought). Thinking, however, is more adaptive than the best simple practical actions (sensori-motor action). Sensori-motor practical action at its best; thinking at its best; logical thought at its best represents a progressive movement towards increasingly flexible and adaptive forms of assimilation/accommodation equilibrium.

II. Piaget’s Theory of the Development of the
Cognitive Dimension of Mind
Readings: Chapter
13, all. Physical and Cognitive Development
I. Status of the Neonate (Newborn infant) as an Organization
of Action Systems (Developmental Psychology doesn’t focus on simple reflexes
much any more)
A. Old Incompetent Infant Story: Infant understood according to the lump of matter model with reflexes added. The empiricist’s story.
B. Newer Super-Competent Infant Story: Infant understood according to the steel filing cabinet model. The nativist story.
C. Recent Action Systems Competent Infant
Story: Infant understood according
to the plant model. The co-action
story.
1. The action systems that are available at birth are termed ‘congenital’ or ‘preadapted’ to distinguish them from ‘innate,’ which not only means present at birth, but also means explained by biology alone.
a. 9 months of developmental co-action between biology and environment have already occurred during the ‘prenatal’ period. So can never say that neonate’s behavior is innate.
2. Neonate has up and functioning three types of congenital action systems. These will be the ground from which the infant will develop mind and consciousness and novel behaviors. These are the neonate’s instruments for developing mind.
a. Sensory Systems
Vision
Hearing
Olfaction
Taste
b. Motor Systems
Perceptual Action (e.g.,
Fantz, Haith)
Sucking --- A system, not a
reflex
Reaching
c. Relational Systems (Systems designed to keep caregiver in proximity)
Visual:
Newborns and 8 wk olds exhibit reliable fixation preferences for
schematic face over rectangular lattices.
Visual – EYE GAZE: Infant
locks eyes onto eyes of holding person
Smell: Neonate prefers (orients
towards) mother’s smell (milk pads) rather than to another’s
Auditory-Vocal: Get “PROTO-CONVERSATIONS”, i.e., turn-taking in
utterances, very early (two to three months) in development.
3. ‘Temperament’ – A fourth congenital action system
a. Differs from other three in that it cuts across the other three & it is about individual differences in the quality and intensity of action.
b. Definition: Temperament refers to congenital dispositions that underlie and modulate the expression of activity, reactivity, emotionality, and sociability.
e.g. ‘Easy Babies’ – Playful, adaptable, regular eating, interested in novelty, vs. ‘Difficult Babies’ and ‘Slow to Warm Up Babies’.
Piaget’s explanation focuses on the cognitive
dimension of mind.
Given we have neonate as an integration of organized action systems
(ignore text which says ‘reflex action’), Piaget’s theory explains how, through
action (assimilation/accommodation/equilibration) in the world, the organism
constructs and transforms mind and consciousness.
The discontinuous qualitative
transformations of mind which exhibit novel characteristics Piaget describes as
‘stages’:
A. Sensori-motor Stage of Mind
(Birth – 18-24mos)
1. Practical action, Not thinking
2. Around beginning of 3rd month. Through action the early
congenital systems become transformed into mental organizations called ‘schemes.
’ Schemes such as the sucking scheme, the looking scheme, the grasping scheme
are characterized by the first level of consciousness, a core consciousness.
Get also first beginnings of a sense of self -- termed 'ecological self'.
3. Around 6 months. Beginning of ‘Object Permanence’. Object Permanence is an index that infant
has a sense of ‘self’ as distinguished from ‘object’ or ‘other’
This is the clear sense of 'ecological self'.
4. Around 10 months. Another transformation of mind.
The novelty is a new level of consciousness that allows conscious
reflection on schemes. Here have
clearer development of a ‘volitional self’ and beginning of an extended
consciousness.
a. Conscious reflection on
grasping, pulling, pushing, looking, reaching means these schemes can be
organized. So have volitional
intentional actions.
B. Preoperational Stage of Mind
I (Begins 18mos --[called sensori-motor stage 6 up to 2 yrs], and goes to 4 years).
1. Next transformation. The novelty is a new level of extended
consciousness that allows reflection on organized schemes (i.e., reflections on
reflections on schemes). The mental
structures that develop here are called ‘operations’. These are simply the co ordinations of the
coordinated schemes.
2. This level of novelty is called ‘thinking’. Thinking is defined as the manipulation of
symbols. So rather than just acting
(schemes), or manipulating action (coordination of schemes), now can manipulate
coordinations using symbols.
a. This leads to discussion of ‘symbols’
and ‘representation’ and ‘language’. Will come back to these in next lecture.
3. New level also leads to a new level of
‘Self’
a. Symbolic Self: Child recognizes self in mirror.
4. ‘Egocentrism’ thinking about
the world as if everyone shares the same perceptions and thought, or same point
of view. This appears with the
beginning of thinking and gradually declines
a. Three mountain task as an index of egocentrism.
5. General characteristic of pre-operational
thinking: Thinking with only islands of
logic. Fragmented thinking. Seeing is believing. Thinking in the
immediate situation in sense of not reflecting on thinking.
C. Preoperational Stage of Mind
II (3 or 4-7)
1. Transformation here allows
level of consciousness for thinking about thinking.
2. Child develops a ‘theory of
mind’. Idea that others have thoughts as
child does. This is the end of
egocentricism.
3. A new sense of self, the Conceptual
Self. A self that thinks about itself.
4. Still lacks a coherent framework (logic) within which to fit thinking.
D.
Concrete Operational Stage of Mind. (7-12).
1. Mental operations that allow thinking about thinking become coordinated. This gives a coherence to reflective thought and coherence = logic. Some refer to these operations “Rules that guide reason.”
2. Novelty at this stage is thinking that is
logical.
3. The Conservation Task is one index of
concrete operational thinking.
a.
‘Conservation’ is defined as ability to maintain a
constant (unchanging) concept in the face of perceptual change.
e.g.,
pour water from a short fat beaker into a tall thin beaker. Amount of water remains the same (same
amount concept) but it looks different.
Young child will say there is a different amount of water after the
pouring, this is non-conservation.
4. Weakness of this type of thinking is that it
is about only the concrete real and fantasy world, it is not about the world of
endless possibilities.
E.
Formal Operational Stage of Mind (12+)
1. Coordination of concrete operations.
2. Novelty is ability to think logically about logical thought.
3. Allows one to begin from abstract principles and proceed to concrete specifics. Thought earlier could proceed only inductively (from specific particulars to abstract universals. Now can also proceed deductively (from general principles to specific particulars.
4. Can imagine worlds that have never been.
5. Can perform scientific thinking of controlling all variables and manipulating one.
6. Can plan and make logical judgments and logical decisions.
7. Higher levels of Self and Consciousness
F.
Post-Formal Thought? Adult
Development
1. Some have claimed there is yet another Stage of thought development. However there is very little evidence for this. Generally this seems to be enough levels of reflection to deal with adult problems. This does not mean that development ends. Will see that motivational and affective development continue when turn to Erik Erikson. Your text mentions the development of Wisdom. This is a dimension of thinking that deeply involves affective and motivational issues.

Chapter 7, pp. 330-end. Language
I. Cognition in Toddlerhood & Beyond: Representation, Symbols, Memory,
&Language.
A. Thinking.
As
stated earlier, for first approximate 18-24 mos. there is no thinking.
Child has practical action of schemes and practical action of
coordination of schemes. Thinking
involves ‘symbols’ and ‘symbolic representation’ and these are not available to
child in sensori-motor stage.
With transformation to the Preoperational Stage child reaches the symbolic level of representation.
1. ‘Representation’ something that
stands for something other than itself.
e.g., Footsteps ‘stand for’ mother.
e.g., Picture of fish ‘stands for’
fish
e.g., Smile ‘stands for’ happy
Infant has representations of the
world, but these are picture like and signal like, and not symbols.
2. ‘Signals and signs’ are
representations. They ‘stand for’
something other than themselves. They
are like conditioned stimuli, E.g.,
again footsteps stand for ‘mother’.
Infant has these available.
3. ‘Symbols’ are representations and
stand for other things, but they are detached from, distinct from, not a part
of, the things they represent.
e.g., I can use a simple piece of wood as a
symbol of an automobile, or a car or boat etc.
This is not a picture of the auto, has no inherent relation to an auto.
e.g., We have the convention of
using a ring as a symbol of friendship or a symbol of marriage etc. This is not a conditioned signal, not a part
of friendship, no inherent relationship to marriage.
e.g., Words are one type of symbol,
not the only type. “Dog” is not a part
of dog. Don’t expect ‘dog’ to bark as a
dog would; not afraid of ‘dog’ as might be of dog etc.
Symbols
are constructed by persons by assigning meaning to the thing that does the
representing.
Symbol
construction is possible only when consciousness has attained a level of reflection that
permits organized action upon organized action.
4. ‘Thinking’ is the manipulation
(action on) of symbols.
B. Memory
1. Two types of memory:
a.
‘Recognition’: This is
based on signals. (e.g., think of taking a multiple choice exam). Infant has signal representation and so has
recognition memory. For example,
remembers mother, father when sees them or when hears their voice,
footsteps.
b.
‘Recall’: This is based
on symbols (e.g., think of taking an essay exam and having to retrieve the
information of facts and events).
Infant does not have symbols and so until around 2 years of age does not
have recall. That is, infant cannot
‘re-present’ symbolically the event earlier experienced.
c.
The two types explain why the adult cannot recall events that happened
when they were 1 year of age. When
someone tells you they remember being given a certain toy at age 1 year, be
skeptical. Probably they were told
about this event many time and constructed a symbolic recall memory at a later
time.
2. ‘Implicit’ memory is probably
related to non-symbolic signal recognition while ‘Explicit’
memory is related to symbolic recall (see pp. 269-270).
3. ‘Procedural’ memory – memories for how to do things-- are related to non-symbolic memory while ‘declarative’ memory—recollections of facts and events – is related to symbolic recall.
4. The process of encoding, storage, and retrieval occur in both types of memories but the specific features of these processes may differ depending upon whether the material is signal like or symbolic.
C. Language and Language Acquisition
1. ‘Language’ is defined as a system
of symbols that functions to express and communicate meanings.
2. Language involves symbols and does not
necessarily involve speech.
e.g., American sign language is
composed of symbols without speech
a.
Verbal language involves a phonetic (sound) system entailing phonemes,
but this is not a necessary subsystem of language.
b.
The infant’s cooing, gooing, and babbling are interesting, but not a
necessary feature of language.
Consequently, they cannot explain language acquisition.
3. Language system is composed of three
subsystems: Semantic, Syntatic, and
Pragmatic subsystems:
a.
‘Semantic’ subsystem:
This has to do with the relationship between the symbol and the ‘referent’
(i.e., what the symbol refers to).
1). The problem: Given that a symbol (in this
case a word) might refer to many things, how does it come to refer to a
specific thing for the child.
e.g.,
How does the symbol ‘Rabbit’ come to refer to the whole animal rather than just
the fur, or just the ears etc.
2). This is the general problem of the ‘Acquisition
of Word Meaning.’
3). This problem becomes resolved when it is
recognized that the child already has the meaning (in a non-symbolic form) and
through the child’s expression of action meaning (pointing, crying, looking
etc), the parent or care giver comes to understand what the child means. This then leads to the parent supplying the
appropriate.
So,
the child actually uses a word as a symbol of the meaning he/she already has,
rather than the having to acquire the meaning of a word.
b.
‘Syntax’ (Grammar) subsystem: System of rules for how symbols can be related to each
other. Or ‘rules by which units of meaning
[words] are combined into larger units [sentences]’.
e.g.,
‘John ate the apple’ ok in English but ‘The apple ate John’ is not.
e.g.,
‘Mary followed the lamb’ and ‘Mary was followed by the lamb’ follow different
rules.
This
area of inquiry is investigated at around 2 when the child reaches the
‘two-word stage’ of language acquisition.
c.
‘Pragmatic’ subsystem: The rules that relate symbols to their
communicative use
1.)
H. P. Grice’s ‘Cooperative Principles (Rules) of Conversation:
Maxim of Quantity: Speak neither
more nor less than is required.
Maxim of Quality: Speak the
truth & avoid falsehood.
Maxim of Relevance: Speak in a
relevant and informative way.
Maxim of Clarity: Speak so as to
avoid obscurity & ambiguity.
4. Language Acquisition:
a.
LUMP OF MATTER MODEL (Nurture)

2. Conditioning
(e.g., Skinner)

STEEL FILING CABINET MODEL (Nature)
1. Noam Chomsky, Steven Pinker
2. Idea of
‘Prewired’ Language Acquisition Device & Linguistic Universals. Called ‘Trigger Nativism.’
3. Evidence from
all early rule following including ‘overregularization’ using rules.
c. PLANT MODEL (Co-action, Interaction)
1. Piaget, Slobin, Lois Bloom
2. ‘Operating principles’ (Slobin)
develop out of the earlier co-action of mental organization and
environment. Operating principles then
at symbolic level function as hypotheses to be tested out in the world.
3. Example of role of environment in
language acquisition: ‘Motherese’ or
‘Child-directed speech’ –
Note,
to this point we have been taking a child-centered point of view and asking
about how the processes of mind develop through the action of the child. However, because this is based on the plant
model of co-action, we know that as some point we must ask the question of how
the environment functions in this development.
This is that point. Here we
change our point of view and instead of looking from the inside out we look
from the outside in.
To
say this slightly differently, given that we are interested in the development
of mind and consciousness through action, what kind of world do we have to
present to mind to best facilitate the mind’s constructive activity. As with a plant, we can’t cause its
development, we can, however, provide it with the nutrients for it to grow.
1. As Piaget focused on the mind and action, Vygotsky focused on the environmental nutrients of mind
2. ‘Zone of Proximal Development’.
The range of ability between observed level of ability and person’s
basic capacity at each stage of development.
Area within which you can offer the child opportunities that he/she can take advantage of for purposes of growth.
e.g., Don’t offer the infant verbal commands (outside ZPD)
1. For maximum facilitation of change offer
opportunities (stimuli, environmental events) that are moderately different
from very familiar events.
Very unfamiliar events cannot be
assimilated, and accommodation breaks down (i.e., infant doesn’t have any way
to change behavior to deal with the extreme novelty), so you get very little
interaction with these stimuli, get aversion or crying.
Very familiar events can be assimilated, but no accommodation is
required so get very little interaction with these stimuli, bet bored behavior.
Moderately discrepant stimuli provide the greatest interaction
C. Styles of Parenting
Notice how the different styles conform to or violate Vygotsky’s and Kagan’s rules.
1. Authoritarian (Brick Wall Parent)
a. Parents tend to be firm, punitive, and unsympathetic. Believe in importance of their authority and value obedience. See child as willful and in need of discipline. Tend to be detached from child and give little praise. Do not take child’s intentions, wishes, desires, level of mind into consideration. Try to shape behavior & child must adjust to parents standards (Use the Lump of Matter Model).
b. Child tends to lack social competence, lacks spontaneity & intellectual curiosity.
2. Permissive (Jelly-Fish Parent)
a. Fail to provide any structure give child more freedom than child can handle.
b. Child tends to be relatively immature and have trouble controlling impulses, acting independently.
3. Authoritative (Back-Bone Parent)
a. Provide structure, firm without being rigid. Rules are presented at level of child’s functioning. There is bi-directional communication, dialogue, and discussion. They establish firm limits which are explained and discussed, and within these limits they encourage independence.
b. Child tends to be more self-reliant, more self-controlled and more willing to explore than others
4. Neglecting (From Maccoby & Martin).
a. Maccoby & Martin divide types along dimensions of demandingness and responsiveness. The neglecting parent can neither control nor be responsive to the child.

Readings: Chapter 14, all. Social Development
B. Three Levels of Affect: (From A. Demasio)
1. Background emotions. E.g., calm-tense, well-being, malaise.
2.
Primary emotions. The
big six: happy (joy, elation), sad, fear, anger, surprise, disgust.
3.
Secondary emotions. Embarrassment,
shame, guilt, pride, jealousy.
C. Development: Two theories:
1. ‘Discrete’ theory: (Nativist – Steel Filing Cabinet Model). All emotions are present at birth. Human neural system innately prewired to sense various emotions given appropriate situation in which to express the emotion.
2. ‘Differentiation’ theory: (Co-action, Plant Model). Neonate begins in global arousal state (congenital emotions) and through action in the world the specific emotions become differentiated or emerge.
D. Development:
Differentiation
1. Background and Primary Emotion Development
a. Neonate begins with global state that ranges from sleep to aroused. In aroused state can have sensations that range from what we would call from pleasure – pain. But have no specific emotions. First emotions to develop are probably background emotions.
b. Pleasure-positive emotions. Involves completion of an action sequence through adaptive or exploratory actions. Pain-negative emotions. Involves failure to resolve or complete action sequence
c. Happy – associated with pleasure -- and sad, disgust, anger – associated with pain -- primary emotions differentiate quite early in first few months. Here have core consciousness.
d. Other primary emotions require that infant have not merely ecological self, but the self con
