CLEP Psychology Flashcards
- Psych
- Scientific study of human behavior (actions you see) & mental processes (thoughts, emotions, impulses
- Structuralist
o Believes in consciousness
o William Wundt
Made up of different elements combined in different ways to produce perceptions
Wanted to discover the form, or basic elements of mental experience
Used introspection- internal perception, process by which someone examines their own conscious experience as objectively as possible
* Subjective way & couldn’t be used on children or animals
- Functionalism
o Function of human condition or behavior, mental experiences or processes adaptive or functional for people
o Believed consciousness & behavior helped people & animals adjust to their environments
- Biological Approach
o Physiological & biochemical explanation of behavior (genes, hormones, neurotransmitters)
o Studying behavior focus on understanding how physiological & biochemical processes produce psychological phenomena
- Behavioral Approach
o Responding to environment, learned responses to predictable patterns of environmental stimuli
o Classical & operant conditioning
- Psychodynamic Approach
o Unmet needs from childhood affects personality
o Thoughts, feelings, & behaviors stem from interaction of innate drives & society’s restrictions on expression of those drives, Psychoanalytic
- Cognitive Approach
o Behavior results of feelings & thoughts, resulted as reaction against behaviorism
o Studies problem solving, attention, expectation, memory, & other thought processes
- Humanistic Approach
o Motivated by desire to grow & develop, believe people aren’t machines whose behaviors determined by genetic code
o Emphasized potential for good innate to all humans
- Social- Cognitive Approach
o Reciprocal determinism
How people think, behave, & what their environment is like all interact to influence consistency of behavior
- Individual-Difference Approach
o Measuring many ways in which people differ, reducing those ways down to manageable subset, using measurements of characteristics to predict actual behavior
o Traits- consistent pattern of behavior
o Measured by self-report questionnaires
- Experimental Approach
o Cause & effect
o Independent variable- manipulated (cause)
o Dependent variable- measured (effect)
o Experimental group- exposed to cause
o Control group- not exposed to the cause (helps to set standard)
o Neuron Types
- Sensory (afferent neurons): take info from body tissues & sense organs, transmit to spinal cord & brain
- Motor (efferent): sends info in opposite direction
- Interneurons (association neurons): neurons communicate with other neurons
Neurons Consist of
- Cell body:
o Contains structure to help keep cell alive - Dendrites:
o Short, bushy fibers that take info in from outside cell - Axons:
o Relatively long fibers that pass info along to other nerve cells, to glands, or muscles - Myelin sheath:
o Fatty tissue that the axon & accelerates transmission of info
o Synapse
Junction where end of one neuron meets beginning of another
* Gap less than one millionth of an inch is the synaptic gap
o Neurotransmitters
Chemical molecules contained in vesicles within axon terminal
Released into synaptic cleft, bind to receptor sites on next neuron’s dendrites
Excess is either broken down due to enzymatic degradation or absorbed through reuptake
o Central Nervous System
Spinal cord
* Enables reflexive behavior, relays info to brain from elsewhere in body
Brain
* Controls physiological & psychological functions
o Peripheral nervous system
Includes sensory & motor neurons connecting the brain & spinal cord to rest of body
Two Systems of Peripheral Nervous system
- Somatic nervous system- operate in external environments
o Carries info from muscles, sense organs, & skin to central nervous system
o Carries messages from central nervous system to skeletal muscles - Autonomic nervous system- regulates body’s internal environment by controlling functioning glands, organs, & some muscles
o Brainstem
Oldest region of brain, begins where spinal cord enters skull, controls breathing & heartbeat
o Thalamus
Sits on top of brain stem, receives info about senses, sends info to higher regions
o Reticular Formation
Runs through brain stem & thalamus, controls arousal & sleep, filters stimuli, sends info to other parts of brain
o Cerebellum
Rear base of brainstem, controls coordination of voluntary movements
o Limbic System
Sits btw older parts & evolved cerebral cortex
Contains several structures
* Hippocampus- processes memory
* Amygdala- influences fear & anger
* Hypothalamus- influences hunger, thirst, & sexual behavior
o Cerebral cortex
Outer covering of brain, involves motor, cognitive, sensory processes
Divided into two hemispheres- left & right
