Karten in diesem Stapel (42)
- 1Memoryencoding, storage, retrieval, explained in different ways by different theories
- 2Forgettingnot remembering, which has more than one explanation
- 3Storagehow information is retained in the brain ready for retrieval
- 4Retrievalgetting stored information out of the memory
- 5Repeated Measuressame participants are used in both conditions (different tests)
- 6Independent Measuresdifferent participant used in each condition
- 7Matched Pairsdifferent, but similar participants are used in each condition. Effort is made to match participants on important characteristics which may effect performance
- 8Experimental Hypothesisis a statement of what is expected (is the alternative hypothesis)
- 9Null Hypothesisany difference or relationship expected is due to chance - there is no relationship or difference as predicted. Tested using statistics
- 10Directional Hypothesis (One-tailed)direction is predicted
- 11Non-directional (Two-tailed)no direction predicted
- 12Independent Variableis changed or manipulated by the researcher. This is to see the effect on the dependent variable
- 13Dependent Variableis measured by the researcher. It changes as a result of the independent variable
- 14Participant Variablesage, gender, experience and mood of the participants
- 15Situational Variablestemperature, noise, interruptions, light
- 16Extraneous Variablesvariables which might affect the results
e.g. situational, participant - 17Experimenter Effectscome from cues or signals from an experimenter that can affect the participant's response
- 18Double-blind techniquethe participants are not aware which group they are in or what the study is about. Neither the person running the study or the participant know precisely what is expected
- 19Single-blind techniquethe participants are not aware of what is expected but the person carrying out the study is
- 20Ecological Validitywhether it has real life applications
- 21Capacitythe size of the store
- 22Durationhow long the information remains in the store
- 23mode of representationthe form in which the information is stored
- 24Encodinghow memories are encoded, which means how they are registered as memories
- 25Storagehow memories are stored, which means how they remain as memories after they have been registered
- 26Retrievalhow we retrieve memories when the output is needed
- 27Confabulationmeans making up bits to fill in a memory so that it makes sense
- 28Rationalisationmeans making something make sense
- 29Memory Traceinformation is laid down and retained in a store as a result of the original perception of an event
- 30Retrieval Cueinformation present in the individuals cognitive environment at the time of retrieval that matches the environment at the time of recall
- 31Context Dependentthe situation or context is different from that at encoding
- 32State Dependentthe person's state or mood is different from that at encoding
- 33Latency Periodtime between signal and recall
- 34Measures of central tendencymode, median and mean
- 35MeanAverage - adding up and dividing by amount
- 36Modeusual score
- 37Meanmiddle score
- 38Rangemeasure of dispersion
- 39Nominal Datawhich are data in categories
- 40Ordinal Datawhich are data in ranks (Mode and Median)
- 41Interval/ratio datamathematical scores and all three measures of central tendency are suitable
- 42Information Processingwhat the cognative approach is about, including input, processing and output, and how these work
