Term
Auditory-Memory Span
Definition
Number of items recalled from short-term memory following an auditory presentation of the items.
Being unable to repeat back auditory sequences longer than two or three words
Term
Orienting Task
Definition
Instructions to focus on a particular aspect (physical, phonemic, semantic) of a stimulus
The purpose is to try to control the kind of memory code formed by requesting that a person make decisions about a particular aspect of the word, such as its pronunciation or its meaning
Term
Levels of processing
Definition
A theory that proposes that “deeper” (semantic) levels of processing enhance memory
o Holds that success in recalling a word depends on the kinds of operations carried out while encoding the word. Retention is determined by the characteristics that are emphasized during initial perception or rehearsal.
Term
Maintenance rehearsal
Definition
Rehearsal that keeps information active in short-term memory
• Results in learning, the probability of recalling a word at the end of the experiment should be a function of the length of time it was maintained in STM
Term
Incidental learning task
Definition
A task that requires people to make judgments about stimuli without knowing that they will later be tested on their recall of the stimuli.
Term
Primary associates
Definition
Words that are strongly associated with each other, as typically measured by asking people to provide associations to words.
Term
Clustering
Definition
Percentage of occasions in which a word is followed by its primary associate during the free recall of words.
Term
Structural Coding
Definition
A memory code that emphasizes the physical structure of the stimulus
• Question asks whether the word is in capital letters
Term
Phonemic Coding
Definition
A memory code that emphasizes the pronunciation of the stimulus
• Question asks whether a word rhymes with another word- the question emphasizes pronunciation
Term
Semantic Coding
Definition
A memory code based on the meaning of the stimulus
• A person must evaluate the meaning correctly
Term
Noncued recall
Definition
Recall that occurs without hints or cues provided by the experimenter
Term
Cued recall
Definition
Recall that occurs with hints or cues, such as providing the questions asked during the judgment phase of a task.
Term
Imprecise elaboration
Definition
Provision or generation of additional material unrelated to remembered material
Term
Precise elaboration
Definition
Provision or generation of additional material closely related to remembered material
Term
Self-generation
Definition
Generation of items by participants in an experiment, rather than the provision of these items by the experimenter
• Recall following self-generation was intermediate between that for precise and imprecise elaboration suggests that students’ elaborations contained a mixture of two types.
o Results: students were able to recall 91% of the target words in the cases where they had generated precise elaborations and 49% in the cases where they had generated imprecise elaborations.
Term
Distinctive item
Definition
An item different in appearance or meaning from other items
• One that really stands out from other items that could interfere with our memory.
Term
Primary distinctiveness
Definition
An item distinct from other items in the immediate context
o Distinctiveness is defined relative to the immediate context.
 Example: a list of words and all words except one are printed in red. That one word that is not is printed in black. When asked to recall the list later, you are more likely to recall the black word rather than the red.
Term
Secondary distinctiveness
Definition
An item distinct from items stored in long-term memory
o Defined relative to information in our LTM rather than to information in the immediate context
 Example: a characteristic of a word’s spelling
Term
Orthographic distinctiveness
Definition
Lowercase words that have an unusual shape
 A word has an unusual shape, as determined by the sequencing of short and tall letter in the word.
• Examples: lymph, khaki, and afghan.
o NOTE: a shape is unusual (distinctive) relative to all other words stored in LTM, not just to words in the immediate context of the experiment.
Term
Emotional distinctiveness
Definition
Items that produce an intense emotional reaction
o Motivated by the finding that events that produce strong emotional responses are sometimes remembered well.
Term
Flashbulb memories
Definition
A memory of an important event that caused an emotional reaction.
o The vivid recollections that most people have of the circumstances surrounding their discovery of a shocking piece of news
Term
Processing distinctiveness
Definition
Creation of a memory code that makes that memory distinct from other memories
o Depends on how we process the stimulus- it is therefore the result of the memory code that we create for an item rather than the characteristics of the item itself.
Term
Encoding Specificity Principle
Definition

 

§  A theory that states that the effectiveness of a retrieval cue depends on how well it related to the initial encoding of an item
