  • Types of Long- Term Memory:
  • Explicit(declarative): w/ conscious recall/ general knowledge 
  • Implicit(non-declarative):w/o conscious recall/ motor cognitive (routine)
Types of Retrieval Failure: 
  • Proactive Interference: disruptive effect of prior learning on the recall of new information
  • Retroactive Interference: disruptive effect of old info. new learning on the recall of old info. 
Misinformation Effect: 
  • incorporating misleading info into one's memory of an event.
  • depiction of an accident
Associative Learning:
  • Learning that certain events occur together. 
  • Ex: Cooking, lose weight 
Three Main Types of Learning 

Classical Conditioning 
It's all started with: Ivan Pavlov. Tested theory on dogs. 
  • Unconditioned Stimulus (UCS): a stimulus that naturally and automatically triggers a response. 
  • Unconditional Response (UCR): the unlearned, naturally occurring response go the UCS. 
  • Conditioned Stimulus (CS): an originally irrelevant stimulus that, after association with the UCS, comes to trigger a response. 
  • Conditioned Response (CR): the learned response to a previously neutral stimulus. 
  • Classical conditioning: obedience, used dogs to study.
Acquisition 
  • The initial stage of learning 
  • The phase where the neutral stimulus is associated with UCS so that the neutral stimulus comes to elicit the CR (this becoming the CS). 
Extinction 
  • The diminishing of a conditioned response. 
  • Will eventually happen when the UCS doesn't follow the CS.
Spontaneous Recovery 
  • The reappearance. After a rest period, of an extinguished conditioned response. 
Generalization 
  • The tendency, once a response has been conditioned, for stimuli to the CS to elicit 
Discrimination 
  • The learned ability to distinguish between a CS and other stimuli that doesn't signal UCS   
  1. Next-in-Line Effect: We seldom remember what the person has just said or done if we are next.
  2. Information minutes before sleep is seldom remembered; in the hour before sleep, well remembered. 
  3. Taped info played while asleep is registered by ears, but we do not remember it. 
Spacing Effect 
  • We encode better when we practice or study over time. 
  • DO NOT CRAM!! 
Serial Positioning Effect 
  • Our tendency to recall best the best the first and last items in a list. 
Chunking: 
  • Organizing items into familiar, manageable units.
  • Often will occur automatically. 
Types of Encoding:

  • Semantic Encoding: the meaning of words
  • Acoustic Encoding: the encoding of sound especially of words
  • Visual Encoding: encoding of picture images 
Tricks to Encode:
  • use imagery- mental pictures 
  • Mnemonic Devices use imagery
  • Ex: Mary very easily makes jam Saturday unless no plums= mars,venus, earth, mercury, jupiter, saturn, uranus, neptune, and pluto


Memory 
  • The persistence of learning over time through storage and retrieval of information. 
The Memory Process 
  • Encoding 
  • Storage 
  • Retrieval 
Encoding 
  • The processing of information into the memory system. 
  • Ex: asking a girl's number from a party
Storage 
  • The retention of encoded material over time.
Retrieval 
  • The process of getting the information out of memory storage 
  • Ex: seeing a girl at the party but forgetting her name and calling her by the wrong name. 
Recall VS. Recognition
  • With Recall - you must retrieve the information from your memory (fill-in-the blank tests).
  • With Recognition - you must identify the target from possible targets (multiple-choice tests).
Flashbulb Memory 
  • A clear moment of an emotionally significant moment or event. 
  • Where were you when?
  • You heard about 9/11? You heard the death of a family member? 
Types of Memory 
  • Sensory Memory 
  • Short - Term Memory 
  • Working Memory 
Sensory Memory 
  • The immediate, initial recording if sensory information in the memory system. 
  • Stored just for an instant, and most gets unprocessed. 
  • Ex: you lose concentration in class during a lecture. Suddenly you hear a significant word and return your focus to the lecture. You should be able to remember what was just before the key word since it's in your sensory register. 
Short - Term Memory 
  • Memory that holds a few items briefly. 
  • Seven digits (plus of minus two) 
  • The info will be stored into long-term or forgotten. 
Working Memory (Modern day STM)
  • Another way of describing the use of short-term memory is called working memory. 
  • Working - Memory has three parts:
  • 1. Audio 2. Visual 3. Integration of audio & visual (controls where attention lies) 
Long- Term Memory 
  • The relatively permanent and limitless storehouse of the memory system. 
Automatic Processing 
  • Unconscious encoding of incidental information.
  • You encode space, time, and word meaning without effort. 
  • Things can become automatic with practice 
Effortful Processing 
  • Encoding that requires attention and conscious effort. 
  • Rehearsal is the most common effortful processing technique. 
  • Through enough rehearsal, what was effortful becomes automatic.

Intelligence

Intelligence

  • refers to the abilities involved in learning or having adaptive abilities
Achievement Test
  • tests that gauge a person's mastery and knowledge of subjects
Aptitude Test
  • tests used to assess talent for specific types of mental ability
Convergent Thinking
  • narrowing down a list of alternatives to converge on a single answer
Divergent Thinking
  • trying to expand the range of alternatives by generating many possible solutions
Factor Analysis
  • statistical analysis of correlations among many variables to identify closely related clusters of variables
Gardner
  • theory of multiple intelligences
  • logical-mathematics, spatial,bodily-kinesthetic, etc
IQ Formula
  • a child's mental age divided by chronological age, multiplied by 100
Mental Age
  • a score that indicates that a child displays the mental ability typical of the child's age
Wechsler Adult Intelligence Scale
  • created by Wechsler
  • most widely used intelligence test
  • it measures verbal and nonverbal intelligence
Stanford-Binet
  • widely used American revision of Binet's original intelligence test
  • revised by Terman
Terman
  • revised Binet's IQ test
  • established norms for american children
Spearman
  • found that specific mental talents were highly correlated
  • concluded that all cognitive abilities showed a common core which we labeled as g (general ability)

Language: 

Babbling Stage

  • at about 4-7 months
  • stage of speech development where the infant spontaneously utters various sounds at first unrelated to household language 
This is a video of twin babies having a conversation with each other. They are still in the babbling stage.

Benjamin Whorf
  • his theory is that language determines the way we think
Grammar 
  • determines how sounds and words can be combined
  • used to communicate meaning within a language
  • has two components which are syntax and semantics.
Morpheme 
  • smallest meaningful units of speech
  • simple words, suffixes, or prefixes
  • Ex: calm, hot
Phonemes 
  • basic sounds units 
  • indicates the change in meaning
One-word Stage
  • the stage in speech development where a child speaks mostly in single words
  • from about 1 to 2 years old
Two-word Stage
  • beginning at about 2 years old
  • stage in speech development where a child speaks two worded statements
Semantics
  • the study of meaning in language
Syntax

  • studies of the rules for forming admissible sentences
Telegraphic Stage
  • early speech stage where the child talks like a telegram
  • Ex: "Go car"
Noam Chomsky 
  • Stated there is an infinite number of sentences in a language
  • humans have an inborn native ability to develop language
Thinking:

Algorithm

  • a methodical, logical rule or procedure that guarantees solving a problem
Available Heuristics
  • estimating the likelihood of events based on their availability in memory; if instances come readily to mind, we presume such events are common.
Cognition
  • all the mental activities associated with thinking, knowing, remembering, and communicating 
Confirmation Bias
  • the tendency to search for info that confirms one's preconceptions
Functional Fixedness
  • the tendency to think of things only in terms of their usual functions
Heuristics 
  • a simple thinking strategy that allows you to make judgments and problem solving more efficient. 
  • more error prone than algorithms 
Mental Set
  • the tendency to approach a problem in a certain way
  • using a way that's been successful 
Over Confidence
  • the tendency to be more confident than correct
  • they overestimate their judgments and beliefs















Representative Heuristics 
  • judging the likelihood of things in terms of how well they represent/ match the prototype. 
  • this could lead someone to ignore relevant information
