Memory Basics and Case Studies
This section introduces fundamental concepts in memory and cognitive processing, as well as the use of case studies in memory research.
Memory is defined as the mental function of retaining information about stimuli, events, images, ideas, etc. after the original stimulus is no longer present. Key cognitive processes involved in memory include:
- Top-down processing: Using prior knowledge to fill in gaps in perception, creating mental schemas
- Bottom-up processing: Building up perception from smallest pieces of sensory information
- Mediation processes: Processes occurring between stimulus and response
The core components of memory processing include:
- Encoding: Converting information into storable forms visual,acoustic,semantic
- Storage: Retaining information in the brain
- Capacity: Amount of information that can be held in memory
- Duration: How long a memory lasts before becoming unavailable
Case studies involve in-depth examination of single participants with unusual traits or experiences. They offer high ecological validity and rich qualitative data, but have limitations in sample size and replicability.
Vocabulary: Triangulation - Gathering data from multiple methods to form an overall conclusion
Highlight: Case studies provide holistic, in-depth data but findings may be subjectively measured and difficult to generalize
