607533035Latent contentaccording to Freud, the underlying meaning of a dream (as distinct from its manifest content)

607533044Classical conditioninga type of learning in which an organism comes to associate stimuli. A neutral stimulus that signals an unconditioned stimulus (US) begins to produce a response that anticipates and prepares for the unconditioned stimulus. Also called Pavlovian or respondent conditioning.
607533045Extinctionthe diminishing of a conditioned response; occurs in classical conditioning when an unconditioned stimulus (US) does not follow a conditioned stimulus (CS); occurs in operant conditioning when a response is no longer reinforced.
607533046Spontaneous recoveryThe reappearance, after a pause, of an extinguished conditioned response.
607533047Generalizationthe tendency, once a response has been conditioned, for stimuli similar to the conditioned stimulus to elicit similar responses
607533048Discriminationin classical conditioning, the learned ability to distinguish between a conditioned stimulus and stimuli that do not signal an unconditioned stimulus

607533050Law of effect(psychology) the principle that behaviors are selected by their consequences
607533051Positive reinforcementincreasing behaviors by presenting positive stimuli, such as food. A positive reinforcer is any stimulus that, when presented after a response, strengthens the response. Adding something positive to see more of the behavior.
607533052Negative reinforcementincreasing behaviors by stopping or reducing negative stimuli, such as shock. A negative reinforcer is any stimulus that, when removed after a response, strengthens the response. (Note: negative reinforcement is not punishment.) Taking away something negative to see more of the behavior.
607533053PunishmentOccurs when stimulus change immediately follows a response and decreases the future frequency of that type of behavior in similar conditions. Taking something good away to see less of the behavior.
607533054Schedules of reinforcementthe rule for determining when and how often reinforcers will continue; Four types of schedules: fixed ratio, variable ratio, fixed interval, and variable interval; interval means over a time and ratio means an act; partial reinforcement is on a variable schedule whereas continuous reinforcement is on a fixed schedule; variable schedules are more effective in learning.

607533056Intrinsic motivationA desire to perform a behavior for its own sake.
607533057Extrinsic motivationA desire to perform a behavior due to promised rewards or threats of punishment.
607533058Observational learningA type of learning that occurs when an organism's responding is influenced by the observation of others, who are called models.
607533059Memorythe cognitive processes whereby past experience is remembered
607533060Long term potentiationan increase in a synapse's firing potential after brief, rapid stimulation. believed to be a neural basis for learning and memory
607533061Mood congruent memorythe tendency to recall experiences that are consistent with one's current good or bad mood
607533062Parallel processingThe processing of several aspects of a problem simultaneously; the brain's natural mode of information processing for many functions, including vision. Contrasts with the step-by-step (serial) processing of most computers and of conscious problem solving.
607533063Flashbulb memoryA clear memory of an emotionally significant moment or event.
607533064Proactive interferenceThe disruptive effect of prior learning on the recall of new information.
607533065Automatic processingunconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings
607533066Amnesiapartial or total loss of memory
607533067Retroactive interferenceThe disruptive effect of new learning on the recall of old information.
607533068Effortful processingEncoding that requires attention and conscious effort.
607533069Implicit memorymemories we don't deliberately remember or reflect on consciously
607533070Explicit memorymemory of facts and experiences that one can consciously know and "declare." (Also called declarative memory.)
607533071Misinformation effectIncorporating misleading information into one's memory of an event.
607533072MnemonicsMemory aids, especially those techniques that use vivid imagery and organizational devices.
607533073Source amnesiaattributing to the wrong source an event we have experienced, heard about, read about, or imagined. (Also called source misattribution.) Source amnesia, along with the misinformation effect, is at the heart of many false memories.
