Q

Inter neurons

A

inter neurons: relay signals between neurons or groups of neurons, are responsible for the processing of information by the brain, like the logic circuits of a computer. also serve to relay signals from place to place within the central nervous system.

24
Wernicke area
Comprehends words
25
Heritability
Proportion of variation among individuals that we can attribute to genes
26
Collectivist
Giving opportunity to the goals of ones group and defining ones identity accordingly
27
Individualistic
Priority to ones own goals over group goals, and defining ones identity in terms if personal attributes rather than group identifications.
28
Gender schema
Children learn from their cultures a concept of what it means to be male and female and that they adjust their behavior accordingly.
29
Gender identity
Ones sense of being make or female
30
Teratogens
Chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm
31
Imprinting
Process by which certain animals form attachments during a critical period very early in life.
32
Maturation
Biological growth process that enable orderly changes in behavior, relatively uninfluenced by experience
33
Attachment
An emotional tie with another person: shown in young children by seeking closeness to the caregiver and showing distress on separation
34
Object permanence
The awareness that things continue to exist even when not perceived
35
Conservation
Properties such as mass, volume, and number remain the same despite changes in the forms of objects
36
Accommodation
All doggies are different than kitties
37
Assimilation
Everything with four legs is a doggie
38
Fluid intelligence
Ones ability to reason speedily and abstractly
39
Crystallized intelligence
Ones accumulated knowledge and verbal skills
40
Absolute threshold
The minimum stimulation needed to detect a particular stimulus 50 percent of the time
41
Difference threshold
Minimum difference between two stimuli required for detection 50 percent of the time.
42
Young helmholtz trichromatic or three color
The retina contains three different color receptors- one most sensitive to red, green, and blue- which when stimulated in combination can produce the perception of any color.
43
Opponent-process
Opposing retinal processes (red-green, yellow-blue, white-black) enable color vision
44
Vestibular sense
Sense of body movement and position, including sense of balance
45
Kinesthesis
System for sensing the position and movement of individual body parts
46
Phi phenomenon
Illusion of movement when two or more adjacent lights blink on and off in quick succession
47
Visual capture
Tendency for vision to dominate the other senses
48
Retinal disparity
Binocular cue for perceiving depth. Compares images from two eyeballs, the brain computes distance.
49
Convergence
Binocular cue for perceiving depth. Eyes converge inwards when looking at an object.
50
Figure ground
Visual field into objects that stand out from their surroundings.
51
Depth perception
Ability to see objects in three demons ions although the images that strike the retina are two dimensional.
52
Selective attention
Focusing of conscious awareness on a particular stimulus, as in the cocktail party effect
53
Cock tail party effect
the phenomenon of being able to focus one's auditory attention on a particular stimulus while filtering out a range of other stimuli, much the same way that a partygoer can focus on a single conversation in a noisy room
54
Awake and relaxed
Alpha waves
55
Stage 1 sleep
Happens in an unrembered moment. Can experience hallucinations
56
Stage 2 sleep
Last 20 minutes. Periodic experience of sleep spindles- rapid bursts, rhythm ethic brain activity
57
Stage 3 sleep
From normal sleep to deep sleep. Small amount of delta waves
58
Stage 4 sleep
Heavy delta waves and this is where children may begin to sleep walk or wet the bed
59
REM sleep
Rapid eye movement, reoccurring sleep stage which vivid dreams commonly occur.
60
Narcolepsy
Sleep disorder characterized by uncontrollable sleep attacks
61
Sleep apnea
Sleep disorder characterized by temporary cessation of breathing during sleep and repeated momentary awakenings.
62
Hallucinations
False sensory experiences, such as seeing something in the absence of an external visual stimulus
63
Dreaming
Sequence of images, emotions, and thoughts passing through a sleeping persons mind
64
Manifest
According to frued, the remembered story line of a dream
65
Latent content
According to frued, the underlying meaning of a dream
66
Depressants
Drugs the reduce neural activity and slow body functions
67
Stimulants
Drugs that excite neural activity and speed up body functions.
68
Classical conditioning
Type of learning in which an organism comes to associate stimuli.
69
Operant conditioning
Type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher.
70
Discrimination
Classical conditioning- learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus.
71
Generalization
Tendency, once a response has | Been conditioned, for stimuli similar to thenconsitionednstimulusnro elicit similar responses
72
Shaping
Operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
73
Extinction
Diminishing of conditioned response
74
Spontaneous recovery
Reappearance, after a pause, of an extinguished conditioned response
75
Positive reinforcers
Increasing behaviors by presenting positive stimuli, such as food
76
Negative reinforcers
Increasing behaviors by stopping or reducing negative stimuli, such as shock.
77
Punishment
Event the decreases the behavior that it follows
78
Observational learning
Learning by observing others
79
Latent learning
Learning that occurs but is not apparent until there is an incentive to demonstrate it.
80
