40

level of awareness of both the world and one’s own existence within the world
41
Alertness
State of being awake and thinking
42
Sleep: Beta Waves
high frequency and occur when the person is alert or attending to a mental task that requires concentration.
43
Sleep: Alpha Waves
awake but relaxing state with our eyes closed; Slower and more synchronized than beta waves
44
Sleep: Theta Waves
Irregular wave forms and higher voltages
45
Sleep: Delta Waves
Low frequency and high voltage waves
46
First Stage of Sleep
Light sleep; Theta Waves
47
Second Stage of Sleep
Slightly deeper. Theta waves, sleep spindles, K | complexes. lower heart rate, lower respiration, lower temperature
48
Third/Fourth Stage of Sleep
Deep sleep; Delta waves; Slow wave sleep; Increased release of growth hormone. Hard to wake someone in this stage of sleep
49
Non-rapid eye movement sleep
First four stages of sleep
50
Rapid-eye movement sleep
The mind appears awake on EEG, but the person is asleep. Eye movements and body paralysis. Mostly BETA waves
51
Paradoxial sleep
- heart rate, breathing patterns, and EEG mimic wakefulness, but individual is asleep - Dreaming is most likely to occur in this stage and associated with memory consolidation
52
Sleep cycle
90 min. Stages: 1-2-3-4-3-2-REM or 1-2-3-4-REM
53
Circadian Rhythm
Internally generated rhythms that regulate the daily cycle of waking and sleeping
54
Melatonin
- Contributes to sleepiness - secreted by pineal gland - Decrease in light stimulates its release
55
Cortisol
Contributes to wakefulness - secreted by adrenal cortex - Increase in light stimulates its release
56
Dreaming
occurs mostly during REM
57
Activation-Synthesis theory
Dreams result from brain activation during REM | sleep --> Activation in brainstem, synthesis in cortex
58
Problem-solving Dream theory
dreams are a way of solving problems; unbound by the normal world’s rules, dreams allow for a different perspective on obstacles
59
Cognitive Process Dream theory
Dreams are simply the sleeping counterpart of our stream of consciousness while we are awake
60
Neurocognitive Models of Dreaming
to unify biological and psychological perspective on dreaming
61
Dyssomnias
make it difficult to fall asleep, stay asleep or avoid sleep | Examples: insomnia, narcolepsy, & sleep apnea
62
Parasomnias
abnormal movement or behaviors during sleep | Examples: night terrors & sleep walking
63
Insomnia
difficulty falling asleep or staying asleep
64
Narcolepsy
lack of voluntary control over onset of sleep
65
Cataplexy
loss of muscle control and sudden intrusion of REM sleep during waking hours
66
Sleep paralysis
sensation of being awake and unable to move despite being awake
67
Hypnagogic & hypnopompic hallucinations
hallucinations when going to sleep or waking up
68
Sleep apnea
inability to breathe during sleep --> often people wake up in order to breathe
69
Obstructive sleep apnea
physical blockage in the pharynx or trachea prevents airflow
70
Central sleep apnea
brain fails to send signals to the diaphragm to breathe
71
Night Terrors
periods of intense anxiety that occur during slow wave sleep (SWS)
72
Sleepwalking or Somnambulism
occurs during SWS
73
Sleep deprivation
can result from one night without sleep, or multiple nights with poor-quality sleep
74
REM rebound
earlier onset and greater duration of REM sleep after one is permitted to sleep normally after a period of deprivation
75
Hypnosis
state in which a person appears to be in control of their functions, but in slightly suggestible state
76
Hypnotic induction
hypnotist seeks to relax the subject and increase subject's level of consciousness
77
Meditation
Quieting the mind for purpose. Used for relief of anxiety
78
Depressants
Reduce nervous system activity -->sensation of relaxation and reduced anxiety (increases GABA activity) -Examples: Alcohol, Barbiturates, and Benzodiazepines
79
Alcohol myopia
short-sighted view of the world
80
Stimulants
Cause an increase in arousal of the nervous system by increasing frequency of action potentials -Examples: Amphetamines, cocaine, and ecstasy
81
opiates/opioids
Causes decreased reaction to pain and sense of euphoria | -Examples: Heroin, morphine, opium, oxycodone & hydrocodone
82
Hallucinogens
Causes distortion of reality and fantasy, enhancement of sensory experiences and introspection Examples: LSD, peyote, mescaline, ketamine
83
Mesolimbic reward pathway
Normally involved in motivation and emotional response. Its activation accounts for the positive reinforcement of substance use Other three pathways: Nucleus accumbens, ventral tegmental area and medial forebrain bundle
84
Attention
Concentrating on one aspect of the sensory environment
85
Selective attention
Allows one to pay attention to particular stimulus while determining if additional stimuli in the background require attention.
86
Divided attention
ability to perform multiple tasks at the same time
87

language acquisition is prime between two years and puberty
101
Language: Sensitive period
time when environmental input has maximal effect on the development of an ability
102
Learning (Behaviorist) Language Theory
- B.F Skinner | - Language acquisition is controlled by operant conditioning and reinforcement by parents/caregivers
103
Social Interactionist Language Theory
Language development is caused by a motivation to communicate and interact with others.
