syntax
the cognitive capacity of human beings that allows us to connect linguistic meaning with linguistic form.
grammar
the system and structure of a language, the rules of grammar help us decide the order we put words in and which form of a word to use.
Language Acquisition device (LAD)
a hypothetical tool in the human brain that lets children learn and understand language quickly.
broca’s area
region of the brain that contains neurons involved in speech function. damage results to broca’s aphasia (controls speaking the words)
wernicke’s area
controls the ability to understand the meaning of words
linguistic relativism
the proposal that the particular language one speaks influences the way one thinks about reality.
Robert Sternberg’s 5 components of creativity
1. expertise- well-developed knowledge—furnishes the ideas, images, and phrases we use as mental building blocks.
2. imaginative thinking skills- provide the ability to see things in novel ways, to recognize patterns, and to make connections. Having mastered a problem's basic elements, we can redefine or explore it in a new way.
3. a venturesome personality- seeks new experiences, tolerates ambiguity and risk, and perseveres in overcoming obstacles.
4. intrinsic motivation- is the quality of being driven more by interest, satisfaction, and challenge than by external pressures
5. a creative environment- innovative/interactive environment sparks, supports, and refines creative ideas

neutral stimulus
a stimulus that elicits a response before conditioning (involuntary)
unconditioned stimulus
a stimulus that leads to an autonomic response
unconditioned response
an automatic response to a stimulus (salivating for food)
conditioned stimuls

(neutral stimulus becomes the conditioned stimulus)
conditioned response
an autonomic response established by training to an ordinarily neutral stimulus
acquisition
the stimulus comes to evoke the conditioned response
generalization
the tendency to respond in the same way to different stimuli
spontaneous recovery
when a conditioned stimulus reappears after extinction
extinction
when a CS no longer elicits a CR because no UCS for a while
Operant conditioning
(VOLUNTARY)behavior becomes more likely to recur if followed by a reinforcer, or less likely to recur if followed by a punisher
Skinner’s box
containing a bar or key that an animal can manipulate
shaping
rewarding successful approximation of a target behavior
discriminative stimulus
a stimulus that elicits a response after associated with reinforcement
Skinner’s operant conditioning belief
behavior that is followed by pleasant consequences is likely to be repeated, and behavior followed by unpleasant consequences is less likely to be repeated
most effective reinforcement
effective teaching must be based on positive reinforcement
Skinner’s operant conditioning criticism
ignores cognitive processes, assumes learning occurs only through reinforcement which is not true, and overlooks genetic predispositions and species-specific behavior patterns which can interfere with it.
positive reinforcement
something is added to increase the likelihood of a behavior
ex: child gets praise from parent for good school grades
negative reinforcement
something is removed to increase the likelihood of a behavior
ex: child cleans room to avoid nagging parents
positive punishment
something is added to decrease the likelihood of the behavior
ex: parent scolding a child for fighting with their sibling
negative punishment
something is removed to decrease the likelihood of a behavior
assimilation
fitting new information into an existing schema
accommodation
creating a new schema or changing it to incorporate new infor
schema
frameworks that organize and interpret information
Sensorimotor
piaget’s first stage, (0-2) explores through sensory and motor contact, develops object permanence, develop stranger anxiety
preoperational
stage 2, egocentric, trial and error, develop theory of mind (other people think differently) pretend play
concrete operational
stage 3 (7-11/12) simple logic, mastery of conservation, can reverse, think logically about concrete objects
formal operational
stage 4 (12 to adulthood) cognitive development, reason like adults, make inferences, can think abstractly
Wilhelm Wundt
established first psychology lab, wanted to measure “atoms of the mind” and fastest mental processes
William James
influenced by Charles Darwin, introduced functionalism (assumes a purpose, why do we smell or have thoughts?)
Sigmund Freud
developed influential treatment process called psychoanalytic psychology (unconscious forces and childhood experiences affect our behavior and mental processes
BF Skinner
behaviorism (observable behavior is important to study, not the unseen mental processes), skinner box, pigeons, operant conditioning
Ivan Pavlov
believed basic laws of learning were same for all animals, studied dogs’ digestive system, produced classical conditioning
Abraham Maslow and Carl Rogers
humanistic psychology, unconditional love for each other, focus on personal growth, “third force” in psychology, study of potential and personal growth
Behavioral approach
how learned and observable behaviors impact behavior and mental processes
Cognitive approach
how interpretations of situations and mental processes impact behavior and mental processes

how behavior and thinking vary across situations and cultures
Survey
a descriptive technique for obtaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of a group
Case studies
a descriptive technique in which one individual or group is studied in depth in the hope of revealing universal principles
Strengths: allow examination of rare or unusual behavior, provide large amount of qualitative data
Limitations: can be misleading, not generalizable, cannot determine cause and effect

procedural memory
stores memory for how things are done, cooking, riding a bike
conditioned memory
if you were classically conditioned to do something, you don’t need to consciously remember it
explicit memory
recall of previously learned information that requires effortful processing
