Q
Cerebral cortex
A
The intricate fabric of interconnected neural cells covering the cerebral hemispheres; the bodies ultimate control and information processing center.
2
Q
Frontal lobes
A
Portion of the cerebral cortex lying just behind the forehead; involved in speaking and muscle movements and in making plans and judgements.
3
Q
Parietal lobes
A
Portion of cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position.
4
Q

7
Q
Somatosensory cortex
A
Area at the front of the parietal lobes that registers and processes touch and movement sensation
8
Q
Association areas
A
Areas of the cerebral cortex that are not involved in primary motor or sensory functions; rather they are involved in higher mental functions such as learning, remembering, thinking and speaking.
9
Q
Plasticity
A
The brains ability to change, especially during childhood, by reorganizing after damage or by building new pathways based on experience
10

56
Habituation
Decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a stimulant, their interest wanes and they look away sooner.
57
The 3 major issues that interest developmental psychologists are:
Nature/nature. Stability/change. Continuity/stages
58
Although development is lifelong, there is stability of personality over time. For example:
Temperament tends to remain stable throughout life

65
Scheme
A concept or framework that organizes and interprets information
66
Assimilation
Interpreting our. Ew experiences in terms of our existing schema
67
Accommodation
Adapting our current understandings (schema) to incorporate new information.
68
Sensorimotor stage
In piaget's theory, the stage (from birth to nearly 2 years old) during which infants know the world mostly in terms of their sensory impressions and motor activities.
69
Object permanence
The awareness that things continue to exist even when not perceived
70
Pre-operational stage
In Piaget's theory, the stage (from about 2 to 6 or 7 years of age.) during which a child learns to use language but does not yet comprehend the mental operations of concrete logic.
71
Stranger anxiety
The fear of strangers that infants commonly display, beginning by about 8 months of age.
72
Attachment
An emotional tie with another person; shown in young children by their seeking closeness to the caregiver and showing distress on separation
73
Imprinting

Reflex
77
Between ages 3 and 6, the human brain experiences the greatest growth in the __________ loves, which enable rational planning and aid memory.
Frontal
78
Which of the following is true of motor-skill development?
The sequence, but not the timing is universal
79
Why can't we consciously recall how we learned to walk when we were infants.
We have no consequence memories of events occurring before about age 3 1/2, in part because major brain areas have not been developed yet.
80
Use Piaget's first 3 stages of cognitive development to explain why young children are not just miniature adults in the way they think.
Infants in Piagets sensorimotor stage tend to be focused only on their own perceptions of the world and may, for example, be unaware that objects continue to exist when unseen. A child in the pre operational stage is still egocentric and incapable of appreciating simple logic, such as reversibility of operations. A preteen in concrete operational stage is beginning to think logically about concrete events but not about abstract concepts.
81
Although Piaget's stage theory continues to inform our understanding of children's thinking, many researchers believe that:
Piaget's stages begin earlier and development is more continuous than he realized
82
An 8th month old infant who reacts to a new a babysitter by crying and clinging to his fathers shoulder is showing:
Stranger anxiety
83
In a series of experiments, the Harlows found that monkeys raised with artificial mothers tended, when afraid, to cling to their cloth mother, rather thank to a wife mother holding the feeding bottle. Why was this finding important?
Before these studies, many psychologists believed that infants became attached to those who nourished them.

116
What is the difference between sexual dysfunctions and paraphilias?
Sexual dysfunctions are problems that men and women may have related to sexual arousal and sexual function
Paraphilias are conditions which maybe classified as psychological disorders in which sexual arousal is associated with nonhuman objects the suffering of self or others and or no consenting persons.
