Storage
Holding information in the memory system.
Retrieval
Recovering information from storage.
Multi-store
The idea that information passes through a series of memory stores.
Sensory store
Hold information received from the senses for a very short period of time.
Short-term store
Holds approxiamately seven chunks of information for a limited amount of time.
Long-term store
Holds a vast amount of information for a very long period of time.
Recency effect
Information that is received later is recalled better than earlier information - because of it being recent (recency)
Primacy effect
The first information received later is recalled better than subsequent information.
Reconstructive memory
Altering our recollection of things so that they make more sense to us.
Structural processing
Thinking about the physical appearance of the words to be learnt.
Phonetic processing
Thinking about the sound of the words to be learnt.
Semantic processing
Thinking about the meaning of the words to be learnt.
Levels of processing
The depth at which information is thought about when trying to learn it.
Interference
THings that we have learnt that make it difficult to recall other information that we have learnt.
Retroactive interference
When information we have recently learnt hinders our ability to recall information that we have previously learnt.
Proactive interference
When information we have already learnt hinders our ability to recall new information.
Context
The general setting or environment in which activities happen.
Anterograde amnesia
Being unable to learn new information after suffering brain damage.

Type theory
Personality types are thought to be inherited. They can be described using related traits.
Extroversion
A personalty type that describes people that look to the outside world for entertainment.
Introversion
A personality type that describes people who are happy with their own company.
Neuroticism
A personality type that describes people who are highly emotional and show a quick, intense reaction to fear.
Personality scales

Antisocial personality disorder
APD - a condition in which the individual does not use socially acceptable behaviour or consider the rights of others.
DSM-IV TR
Lists different mental disorders and the criteria for diagnosing them.
Amygdala
Part of the brain that is involved in emotion.
Grey matter (cerebral cortex)
The outer layer of the brain.
Prefrontal cortex
The very front of the brain. It is involved in social and moral behaviour and controls aggression.
Socioeconomic factors
Social and financial issues that can affect an individual.
Media
Means of communication - television, radio, the internet and newspapers.
Role model
Someone who a child looks up to and is likely to copy.
Prejudice
A rigid set of attitudes or beliefs towards particular groups of people. These attitudes are usually negative but not always.
Discrimination

F-scale
The questionnaire used by Adorno to measure personality characteristics.
Robber's Cave

A group of people you believe you have nothing in common with. For example - people you have never met before.
Jigsaw method
The name given to the technique used by Aronson to reduce prejudice within a group of mixed race students.
Expert groups

Contact
Seeing, speaking or writing to someone.
Empathy

Hypothesis
A testable statement about the relationship between the two variables. In an experiment these variables are called the independent and the dependent variable.
Variable
A factor or thing that can change - it varies.
Independent variable (IV)
The variable that the researcher alters or manipulates to look for an affect or another variable. This varies produces the two conditions of the study. (The thing I change.)
Dependent variable (DV)
The variable that the researcher measures to see if the IV has affected it.
Experiment
The method of research in which all variables other than the IV and DV are controlled. This allows the researcher to identify a cause - and - effect relationship between the IV and DV.
Condition
An experiment is usually organised, there are two trials, after which the performances of the participants are compared. These are the conditions of the experiment.
Participant
A person who is selected to take part in the study.
Order effect
This occurs when the participant's performance in the second condition of an experiment is affected because they have already done the first condtion. They may do better because of practice or worse because of tiredness. This may happen in a repeated measures design.
Participants variables
The differences between the people who take part in the study. These may affect the results of an experiment that uses independent groups design.
Standardised procedures
A set order of carrying out a study that is applied to all participants when necessary.
Random allocation
A procedure for putting participants in to conditions by chance.
Counterbalancing
A procedure for evening out the order in which participants complete both conditions of an experiment.
Instructions
The written (or verbal) information given to participants during the experiment.
Extraneous variable (EV)
A variable that is not the IV but may affect the DV if its not controlled.
Control
Making sure procedures are the same when necessary. Not controlling procedures leads to the possibility of EV occurring and confounding the results.
Randomisation
Using chance to produce an order for a procedure.
Ecological validity
The results of the investigation can be said to apply to real life behaviour. They are an accurate account of behaviour in the real world.
Objectivity
Not affected by people being bias.
Sample
The small group of people who represent the target population and who are studied on.
Target population
The large group of people the researcher wishes to study.
Representative
The sample of participants is made up of people who have the same characteristics and abilities as the target population.
Generalised
The results from the sample can be said to apply to the target population.
Random sample
Every member of the population has an equal chance of being selected for the sample.
Opportunity sample
People who are members of the target population and are available and willing to take part.
Systematic sample
Every 'nth' member of the target population is selected for the sample.
Stratified sample
To obtain this type of sample, the different subgroups in the target population are identified; then people are randomly selected from these subgroups in proportion to thier numbers in the target population.
Raw data
The scores collected in a study that have not been analysed or summarised.
Mean
A statistic calculated by adding all the scores in a set of values and dividing the total by the number of values in the set.
Median
The middle value/number in a set of values when the values have been arranged in ascending order.
Range
The difference between the lowest and highest value in the set of values.
Anomalous result
An extremely high or low result that does not match the other results in a set of values.
Percentage
A proportion expressed as a fraction of 100.
Ethical issues
Points of concern about what is morally right.
