Final Exam Flashcards
Correlation
existence of a consistent, systematic relationship between two events, measures, or variables
-does not demonstrate causation
Independent Variable
condition(s) altered by the experimenter; experimenter sets their size, amount, or value
Dependent Variable
demonstrates the results of the experiment; the variable that is used to measure a change
Double-blind experiment
the subjects AND the experimenters have no idea whether the subjects are in the control or experimental groups
Hypothesis
a testable prediction, often promoted by a theory, to enable us to accept, reject, or revise a theory
Central Nervous System
the brain and spinal cord; interconnected neurons form networks in the brain
(Nervous system: consists of all the nerve cells; body’s speedy, electrochemical communication system)
Cerebellum
“little brain” attached to the rear of the brain stem; helps coordinate voluntary movements and balance
Neuron
basic unit of the brain and the rest of the nervous system
Reticular Formation
nervous network in the brainstem that plays an important role in controlling arousal
NREM Sleep
not REM sleep; stages 1-4
REM Sleep
After reaching the deepest sleep stage(4), the sleep cycle starts moving backward towards stage 1.
Although still asleep, the brain engages in low-amplitude, fast and regular beta waves (15-40cps) much like awake-aroused state
Microsleep
brief shift in brain-wave patterns similar to those of sleep
Altered-state of Consciousness
awareness that is distinctly different in quality or pattern from waking consciousness
Psychological Dependence
Drug dependence based on psychological or emotional needs
Piaget’s stages of Stages of Cognitive Development
Jean Piaget: Concrete Operational Stage
• Concrete Operational Stage (7-11Years): Children become able to use concepts of time, space, volume, and number BUT in ways that remain simplified and concrete, not abstract.
• Conservation: Mass, weight, and volume remain unchanged when the shape or appearance of objects changes.
Jean Piaget: Formal Operations
• Formal Operations Stage (11 Years and Up): Thinking now includes abstract, theoretical, and hypothetical ideas.
• Abstract Ideas: Child is able to understand difficult abstract concepts such as love and prejudice.
• Hypothetical Possibilities: Hypothetical or “what if” thinking is present for the first time.
Object Permanence
the awareness that things continue to exist even when not perceived
Erickson’s stages of development
Erik Erikson’s Eight Stages of Psychosocial Dilemmas
• Stage One: Trust versus Mistrust (Birth-1): Children are completely dependent on others
• Stage Two: Autonomy versus Shame and Doubt (1-3): Doing things for themselves vs. overprotective parents.
• Stage Three: Initiative versus Guilt (3-5): Encourage and support the child in their interests vs. criticizing
• Stage Four: Industry versus Inferiority (6-12): Praised for productive activities
• Stage Five (Adolescence): Identity versus Role Confusion: Adolescents; “Who am I?”
• Stage Six (Young adulthood): Intimacy versus Isolation: Able care about others vs. feeling alone
• Stage Seven (Middle adulthood): Generativity versus Stagnation: Guiding next generation
• Stage Eight (Late adulthood): Integrity versus Despair: Self-respect vs. regret
Classical Conditioning
(a.k.a. Pavlovian conditioning)
– Association between 2 previously unrelated stimuli
Operant Conditioning
(a.k.a. instrumental conditioning)
– Association between acts and their consequences
Digit-span Test
Test of attention and short-term memory; string of numbers is recalled forward or backward
– Typically part of intelligence tests
Repression
Unconsciously pushing painful, embarrassing or threatening memories out of awareness/consciousness
Flashbulb memories
- Memories created during times of personal tragedy, accident, or other emotionally significant events that are especially vivid
- Most often formed when an event is surprising, important, or emotional.
- Includes both positive and negative events
- Great confidence is placed in them even though they may be inaccurate
Concept Formation
Process of classifying world into meaningful categories
Semantics
Study of meanings in language
