Principles of Development Development is orderly and predictable. While development is continuous, it occurs in spurts, and this
gives the appearance of stages of development (Piaget, Freud, Kohlberg, etc.). ‘from head to foot’
Revision 2006 PSB
________________ from head to foot A child can turn its head before it can use its legs.
________________ ‘from center to periphery’ Motor control of the thigh precedes control of the foot. Gives the appearance of gross undifferentiated movements.
Principles of Development Development is dependent upon the interplay
between experience and maturation. _________ Period - Disruption of development
leads to permanent impairments (German measles

leads to permanent impairments (German measles at 3 mo gestation produces mental retardation in newborns).
__________ Period - Disruption of development leads to an impairment that may be partially overcome (language learning after puberty).
Motor Development
Infants begin to roll over first followed by sitting unsupported, crawling, and finally walking. Experience
has little effect on this sequence.

Piaget
Swiss, born in 1896-1980. At age 10 he published his first scientific article on the
habits of an albino sparrow. At age 16 he was recognized as an expert on mollusks
Revision 2006 PSB
At age 16 he was recognized as an expert on mollusks, and was recommended for the post of curator of the Natural History Museum in Geneva.
Received his Ph.D. in Natural Science at age 21.
Piaget
Learning involves the ‘construction of an understanding’ that emerges as a consequence of an encounter between the individual and the environment.
A person seeks to understand his world by applying his

p y pp y gschemas to objects and events.
If an understanding is not achieved the individual must develop a new schema to better accommodate novel features of the world.

Stages of Development Each stage is qualitatively different from others Ages for stage transitions are approximate Sensorimotor
Revision 2006 PSB
Sensorimotor Preoperational Concrete Operational Formal Operational
Sensorimotor Period
Birth to age 2. Child learns that some portions of the world
can be manually manipulated.
Revision 2006 PSB
Chief accomplishment is the development of the concept of object permanence (objects still exist even when out of sight).
No mental images or symbolic thought.
Cognitive Development Object _____________ the awareness that things continue to exist even
when not perceived
Revision 2006 PSB
Separation Anxiety
Separation anxiety is a fear reaction in response to the absence of the primary caregiver.
It is seen in all cultures
Revision 2006 PSB
It is seen in all cultures. It corresponds with the
development of object permanence and the sensorimotor stage of cognitive development.
Preoperational Period Age 2 to age 6. Development of _____________ permits the child to exhibit
imagination, make-believe and imitation. Child is not locked in the present, can talk about yesterday, and
plan for tomorrow. ____________ – the child is a prisoner of his own perspective

Revision 2006 PSB
Concrete Operational Period Ages 7 to 12. As operational logic develops thought becomes less bound by
intuition. Operation – mental transformation. Which is more?
Number
Revision 2006 PSB
Number Length Volume As mathematical skills develop (add, subtract, divide,
multiply) more advanced conservation tasks can be solved. Children in this stage are also able to transform
mathematical functions. So if, 4 + 8 = 12 then transformation 12 – 4 = 8 is also readily doable.
Speed of Information Processing
Revision 2006 PSB
Response times decrease from 7 - 12 years of age Consistent across several different types of tasks
This may be due to the biological maturation of the brain Increased myelination of axons which speeds up neural processing
Formal Operational Period Age 12 through adulthood. Abstract adult logic develops. If A=B, and B=C, then A=C. Balance beam problem: weight can be added to

Cooperative Learning: Baby Einstein
Does listening to Mozart turn babies into brainiacs? In 1998 the Governor of Georgia budged funds to provide all newborns in a free Mozart CD. The idea was that listening to the CD would boost the infant’s intelligence.
Meet with your group and discuss any action that the Alabama legislature should take to promote infant intellectual development. Should the state provide classical music CD’s, play dough, or something else for newborns?

Most stutters can sing fluently, or during choral reading (the rhythm is provided by external cues).
Some stutters may be fluent on stage (someone else is doing the talking).
The more emotionally charged the message, the greater the risk of disfluencies.
Stuttering
Most children go through a stage of dysfluencies between 3-4 years of age. If they are ignored they usually cease within a short period.
20-30% of normal children exhibit a disfluency rate
Revision 2006 PSB
20 30% of normal children exhibit a disfluency rate that exceeds that of many children who stutter.
It is difficult for untrained listeners to distinguish between normal and abnormal disfluencies.
Stuttering is a disorder of early childhood: 85% of stuttering cases begin before age 5.
75% of childhood stuttering recovers by age 8.
Stuttering The magnitude of disfluency varies with the
psychological (treacherous) relationships between the speaker and the listeners.
The emergence of a morbid awareness of the risk of being dysfluent aggravates the difficulty
Revision 2006 PSB
being dysfluent, aggravates the difficulty. Being labeled as a stutterer makes the disorder more
persistent. The more severe the stuttering, the longer it is likely
to persist. If stuttering persists beyond adolescence it may become a life-long disorder.
Recovery from stuttering is a gradual process.
