Q

Auditory Impairment

A

a special need that involves the loss of hearing or some aspect of hearing

30
Q

Speech Impairment

A

Speech that deviates so much from the speech of others that it calls attention to itself, interferes with communication, or produces maladjustment in the speaker

31
Q

Stuttering

A

substantial disruption in the rhythm and fluency of speech; the most common speech impairment

32
Q

Presbyopia

A

a nearly universal change in eyesight during middle adulthood that results in some loss of near vision

33
Q

Glaucoma

A

a condition in which pressure in the fluid of the eye increases; either because the fluid cannot drain properly or because too much fluid is produced

34
Q

Presbycusis

A

loss of the ability to hear sounds of high frequency

35
Q

Peripheral Slowing Hypothesis

A

the theory that suggests that overall processing speed declines in the peripheral nervous system with increasing age

36
Q

Generalized Slowing Hypothesis

A

the theory that processing in all parts of the nervous system, including the brain, is less efficient

37
Q

Cephalocaudal Principle

A

growth follows a direction and pattern that begins with the head and upper body arts and then proceeds to the rest of the body

38
Q

Proximodistal Principle

A

states that development proceeds from the center of the body outward

39
Q

Principle of Hierarchical Integration

A

states that simple skills typically develop separately and independently
-later these simple skills are integrated into more complex ones

40
Q

Principle of Independence of Systems

A

which suggests that different body systems grow at different rates

41
Q

Autostimulation

A

active sleep in infants

  • similar to REM sleep in adults
  • researchers think it provides a means for brain to stimulate itself
42
Q

Growing Body

A
  • by age 2, 25 to 30 pounds and close to 36 inches tall

- by 6 years old, about 46 pounds and 46 inches tall

43
Q

Gender Differences

A

-at age 2 differences are relatively small, during the preschool years boys start becoming taller and heavier, on average, than girls

44
Q

National and Global Economic Differences

A

-profound differences on height and weight between children in economically developed countries and these in developing countries

45
Q

Preschooler fat burns off

A
  • less round + chubby more slender
  • arms and legs lengthen
  • head size more adult-like
46
Q

Internal Physical Changes Occur

A
  • muscle size increases, and children grow stronger
  • bones become sturdier
  • the sense organs continue to develop
47
Q

Middle childhood body change

A

see how we grow

  • height changes
  • weight changes
  • only time in life span when on average girls are taller than boys
  • variation in height up to 6 inches
48
Q

Consequences of Inadequate Nutrition

A

Undernutrition- is implicated in more than half of all child deaths worldwide
Undernourished children:
-lowered resistance to infection
-more likely to die from common childhood ailments and respiratory infections
-frequent illness that impacts growth

49
Q

Puberty In Girls

A
  • begins earlier for girls than boys
  • start around age 11 or 12
  • wide variations in menarche among individuals
  • influenced by environment
50
Q

Puberty In Boys

A
  • Penis and Scrotum begin to grow at accelerated rate around age 12 and reach adult size about 3 or 4 years later
  • enlargement of prostate gland and seminal vesicles
  • sperm arch(ejaculation) around age 13
51
Q

Ups and Downs of Midlife

A
  • emotional reactions to physical changes depend in part on their self-concepts
  • self-image is tied closely to one’s physical attribute
  • but..middle aged adults generally report no less satisfaction with their body images than younger adults
52
Q

Changes in Internal Function

A
  • brain becomes smaller + lighter with age
  • reduction of blood flow to the brain
  • space between the skull and the brain doubles from age 20 to 70
  • number of neurons, or brain cells, declines
53
Q

Nervous System

A

brain and nerves that extend throughout the body

54
Q

Neurons

A

are basic cells of nervous system

-have a cell body containing a nucleus, but unlike other cells, neurons can communicate with other cells

55
Q

Dendrite

A

receive the messages

56
Q

Axon

A

at the opposite end, the part of the neuron that carries messages destined for other neurons

57
Q

Neurotransmitters

A

chemical messengers that travel across the small gaps between neurons

58
Q

Synapses

A

the name for the small gaps hat chemical messengers travel across

59
Q

Gender- related lateralization differences

A

Boys:
-greater lateralization of language in left hemisphere
-higher autism incidence
Girls:
-language is more evenly divided between two hemispheres
-verbal abilities emerge earlier in girls because girls receive greater encouragement for verbal skills than boys

60
Q

Adolescence prefrontal cortex is biologically immature

A

ability to inhibit impulses is not fully developed
-rather than simply reacting to emotions such as anger or rage, an individual with a fully developed prefrontal cortex is able to inhibit the desire for action that stems from such emotions
more developed= not likely to get angry so easily
