25
Sensation
the physical stimulation of the sense organs
26
Perception
The sorting out, interpretation, analysis, and integration of stimuli involving the sense organs and brain
27
Multimodal Approach to Perception
the approach that considers how information that is collected by various individual sensory systems is integrated and coordinated
28
Visual Impairment
a special need that involves significant loss of sight
29
Auditory Impairment
a special need that involves the loss of hearing or some aspect of hearing
30
Speech Impairment
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
Stuttering
substantial disruption in the rhythm and fluency of speech; the most common speech impairment
32
Presbyopia
a nearly universal change in eyesight during middle adulthood that results in some loss of near vision
33
Glaucoma
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
Presbycusis
loss of the ability to hear sounds of high frequency
35
Peripheral Slowing Hypothesis
the theory that suggests that overall processing speed declines in the peripheral nervous system with increasing age
36
Generalized Slowing Hypothesis
the theory that processing in all parts of the nervous system, including the brain, is less efficient
37
Cephalocaudal Principle
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
Proximodistal Principle
states that development proceeds from the center of the body outward
39
Principle of Hierarchical Integration
states that simple skills typically develop separately and independently -later these simple skills are integrated into more complex ones
40
Principle of Independence of Systems
which suggests that different body systems grow at different rates
41
Autostimulation
active sleep in infants - similar to REM sleep in adults - researchers think it provides a means for brain to stimulate itself
42
Growing Body
- 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
Gender Differences
-at age 2 differences are relatively small, during the preschool years boys start becoming taller and heavier, on average, than girls
44
National and Global Economic Differences
-profound differences on height and weight between children in economically developed countries and these in developing countries
45
Preschooler fat burns off
- less round + chubby more slender - arms and legs lengthen - head size more adult-like
46
Internal Physical Changes Occur
- muscle size increases, and children grow stronger - bones become sturdier - the sense organs continue to develop
47
Middle childhood body change
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
Consequences of Inadequate Nutrition
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
Puberty In Girls
- begins earlier for girls than boys - start around age 11 or 12 - wide variations in menarche among individuals - influenced by environment
50
Puberty In Boys
- 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
Ups and Downs of Midlife
- 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
Changes in Internal Function
- 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
Nervous System
brain and nerves that extend throughout the body
54
Neurons
are basic cells of nervous system | -have a cell body containing a nucleus, but unlike other cells, neurons can communicate with other cells
55
Dendrite
receive the messages
56
Axon
at the opposite end, the part of the neuron that carries messages destined for other neurons
57
Neurotransmitters
chemical messengers that travel across the small gaps between neurons
58
Synapses
the name for the small gaps hat chemical messengers travel across
59
Gender- related lateralization differences
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
Adolescence prefrontal cortex is biologically immature
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
61
Rooting Reflex
neonates tendency to turn its head toward things that touch its cheek
62
Steeping Reflex
movement of legs when held upright with feet touching the floor
63
Swimming Reflex
infants tendency to paddle and kick in a sort of swimming motion when lying face down in a body of water
64
Grasping Reflex
infants fingers close around an object placed in its hands
65
Moro Reflex
activated when support for the neck and head is suddenly removed. The arms of the infant thrust outward and then appear to grasp onto something
66
Babinski Reflex
an infant fans out its toes in response to a stroke on the outside of its foot
67
Startle Reflex
an infant, in response to a sudden noise, flings out its arms, arches its back, and spreads its fingers
68
Eye-blink Reflex
rapid shutting and opening of eye on exposure to direct light
69
Gag Reflex
an infants reflex to clear its throat
70
Sucking Reflex
infants tendency to suck at things that touch its lips
71
Cataracts
cloudy or opaque areas of the lens of eye that interfere with passing light, frequently develops -cataracts can be surgically removed
