Multi-Store Model (MSM)
Proposed that memory consisted of 3 stores.
- A sensory register
- Short-term memory
- Long-term memory
Short Term Memory
- Lasts about 12 seconds
- Has a limited capacity
- Only for important sensory information
Long Term Memory
- Regularly rehearsed information
- Has unlimited capacity
- May last forever
Working Memory Model (WMM)
- Suggests that short-term memory is not a single store, but rather consists of a number of different stores
- A hypothetical model of STM
- Includes several components in contrast to the MSM’s version of STM as one big store
Visuospatial-Sketchpad
- The visual component of STM
- Temporary store for visual & spatial information either from sensory memory or LTM
Phonological Loop
- The auditory component of STM
- Divided into 2 components
Episodic Buffer
- Temporarily holds several sources of information active at the same time, while considering what’s needed in the present situation
- Acts as a temporary & passive display store until information is needed
- Limited capacity
- Responsible for our conscious awareness
Displacement
In the MSM this is what happens to information in STM if it is not rehearsed. It is displaced - or “knocked out” of the STM store by other incoming stimuli.
Rehearsal
Plays a key role in determining what is stored in long-term memory in the multi-store model of memory.
Schema Theory
How humans process incoming information, relate it to existing knowledge & use it
Schema
- Mental representations that are used to organise our knowledge, assist recall, guide our behaviour, predict likely happenings, and help us to make sense of current experiences.
- Cognitive structures that are derived from prior experience and knowledge.
Assimilation & Accommodation
Take in & understand fully
Dual Processing Model
Two basic modes of thinking
System I Thinking
- An automatic, intuitive & effortless way of thinking
- Often employs heuristics
- Context-dependent - focuses on existing evidence & ignores absent evidence
- Concerns everyday decision-making
- Generates impressions & inclinations
- Not logic based
- Prone to error
- Operates automatically & quickly with little or no effect
System II Thinking
- Slower, conscious & rational way of thinking
- Abstract
- Conscious reasoning
- Logical
- Reliable
- Slow & requires effort
- Transfers information from one situation to a new situation
Heuristics
Mental shortcuts that involve focusing on one aspect of a complex problem & ignoring others
Reconstructive Memory
The theory that when memories are accessed, they are not retrieved as a single, whole memory, but rather as a collection of independent memories put together.
The Misinformation Effect
The tendency for post-event information to interfere with the memory of the original event.
Framing Effect
- The bias where people react differently to a particular decision depending on how it’s presented emphasising either the positive (gain) or negative (loss) aspects. -
- It can alter people’s responses.
Flashbulb Memory
- Brown & Kulik’s theory that memories created as the result of high levels of emotion – particularly surprise – are like “photographs.”
- The theory argues that a lot of peripheral and irrelevant information is retained.
HPA Axis
- The main stress response system.
- The neuroendocrine link between perceived stress & physiological reactions to stress
