Infants By Martha Peláez, Ph.D. Florida

2Language Development
An infants cry is the babys first use of
language. The Cry begins as a reflex and emerges
as a major means of communicating discomfort and
distress. (Widerstrom,A.H., Mowder,B.A.,
Sandall, S.R.)
3 Language Development Cont. (ISCI)
Infant Scale of Communicative Intent (ISCI) Birth
1 mo. Some vocalizations Nasalized
vowels Begins to cry for attention 12
mo. Begins differentiated cry Gurgles
response to stimulation Produces short vowel
sounds Cries for social stimulation 2-3
mos. Definitely coos Makes glottal-velar
consonants Takes turns when communicating

call 13-14 mos. Has six-word
vocabulary Points to desired object Tries
to sing Imitates other children 14-15
mos. Has up to eight-word vocabulary Initiates
give and take Uses modifiers
8 Language Development Cont. (ISCI)
15-16 mos. Starts using double syllable
words May label pictures Pulls at wet
pants/diaper Pulls adult hand to show
something 16-17 mos. Uses extended phrases
for vocal play Uses differentiated object
names Gradually increases vocabulary May
ask what that? 17-18 mos. Has up to
twenty-word vocabulary Ask for more Makes
successive single-word utterances
9Recommended Parental Behaviors
- Talk, read, and sing to infants - they learn from
everything they see and hear even in the first
stages of life. - Take your baby to the park, zoo, and the store
with you. Bring her attention to objects, signs,
and people. - Always make books a part of your baby's toy
selection, even if he enjoys handling books more
than being red to.
10Recommended Parental Behaviors
- As your child grows, point out pictures of
objects and offer their names. Eventually, your
child will be able to name the pictures, too. - Encourage associations between symbols and their
meaning - as they get closer to toddlerhood,
children may begin to recognize familiar signs
for products and logos for cereal or fast food
restaurants.

16Motor Development Continued
- There are two skills taken into
consideration when assessing motor developmental
skills. These skills are - Gross Motor - Locomotor Skills
- Fine Motor Manipulative Skills

24Development of Social Skills
It is important to remember that, during
infancy, children are learning social skills
primarily from their parents--children's first
teachers. (Harrington, R.)

Source From Infant Development at Risk by Anne
H. Widerstrom, Barbara A. Mowder, Susan R.
Sandall with invited contributors from Robert E.
Nickel, Helen Harrison, and Harriet Able-Boone,

Wall, 1978)
26Piaget and Vygotsky
27Stages in theories of development
28Piaget
- Relied upon clinical method, using probing
questions to uncover what children understood - Was interested in errors children make and the
possibility that these were not random - Searched for a systematic pattern in the
production of childrens errors - Worked towards logically, internally consistent
explanation of childrens errors - Studied how knowledge is acquired and developed
theory of genetic epistemology
- Studied thought and language in pre-schoolers and
early school-age children - Believed that intelligence arises progressively
in the babys repetitive activities - Described how concepts of space, time, causes,
and physical objects arise in development - Investigated the beginnings of fantasy and
symbolism in infancy - Outlined a theory that states that the precursors
of thinking and language lie in the elementary
actions, perceptions, and imitations of babies - Influenced by evolutionary theory child has to
adapt to environment by altering cognitive
structures
29Piagets stages of development
Piagets four stages of cognitive development
Mechanism of change adaptation (Assimilation
Accommodation)
30Piagets stages of development
- Sensorimotor Stage (6 substages)
- Modification of reflexes (0-1 month)
- 2. Primary circular reactions (1-4 months)
- 3. Secondary circular reactions (4-8 months)
- 4. Coordination of secondary schemes (8-12
months) - 5. Tertiary circular reactions (12-18 months)
- 6. Mental combinations (18-24 months)
31Evaluation of Piagetian Theory
- General framework influential
- Much of it wrong in detail
- Notion of domain-general stages dubious, notion
of general purpose cognitive processes also
challenged - Under-estimated abilities of infants
- Theory too impoverished to explain language
development - No obvious explanation for increase in "power" of
cognitive system with age (e.g., how can child
learn to be cleverer?) - Little emphasis on social or emotion factors, or
on abnormal development / developmental disorders
32Vygotsky
- Concerned with historical and social aspects of
human behaviour that make human nature unique - Social and cultural factors are important in the
development of intelligence - Speech carries culture in that it stores the
history of social experience and is a tool for
thought - People are different from animals because they
use tools to create artefacts that change the
conditions of life
- There is a close link between the acquisition of
language and development of thinking - Gave prominence to the importance of social
interaction in development as it influences
language and thought - Does not deal with fixed stages of development
but describes leading activities typical of
certain age periods around which intellectual
development is organised
33Social Learning Findings of Peláez et al.
- Social Behavior as Reinforcers
- Proximity- at moment of nearness, the mother
- Attention and Mands- verbal behavior on behalf
of the parent - Affection- behavior that elicit feelings hugs,
kisses, smiles, pats, nuzzling. tickling - Observational Learning
- Operant Approach
34Social Learning Findings of Peláez et al.
- The Origins of Social Phenomena
- Attachment Separation (as early as 6 mos.)
- The Power of Touch
- Two Types of Touch (massage vs. poking)
- Fear
- Fear of the Dark and Strangers
- Social Referencing
- Conditioning of Meaningless Arbitrary Cues
- Conditioning of Joyful Fearful Originally
Meaningful Maternal Cues
35 Social Learning Findings of Peláez et al.
- Sibling Rivalry Jealousy
- Social Cognition Environment
- Carrying Position Affects Infant Behavior
- Prosocial Behaviors in Early Childhood
