Study Notes
Human Memory
- Memory is the process of retaining, retrieving, and using information about stimuli, images, events, ideas, and skills after the original information is no longer present.
- The modal model of memory, proposed by Atkinson & Shiffrin (1968), describes memory as a flow of information through different stages: Sensory memory, Short-term memory, and Long-term memory.
- Sensory memory holds information for a very brief period, typically less than a second. Iconic memory is for visual information and echoic memory is for auditory information.
- Short-term memory (STM) holds information for about 15-30 seconds without rehearsal. Its capacity is limited, typically 5-9 items.
- Long-term memory (LTM) stores information for extended periods, potentially years.
- Control processes, such as rehearsal, help transfer information from STM to LTM.
- The serial position curve demonstrates that memory is better for items at the beginning (primacy effect) and end (recency effect) of a list.
Modal Model of Memory
- Information flows from sensory memory to short-term memory, then potentially to long-term memory.
- Sensory memory holds information briefly based on the sensory input.
- Short-term memory is where information is actively processed and maintained for immediate use.
- Long-term memory permanently stores information for later use.
Working Memory
- Working memory is a more sophisticated conceptualization of short-term memory. It involves temporary storage and manipulation of information.
- It has three core components:
- Phonological loop: processes verbal and auditory information. It consists of a storage component and a rehearsal component.
- Visuospatial sketchpad: processes visual and spatial information.
- Central executive: coordinates the activities of the phonological loop and visuospatial sketchpad, and connects to long-term memory.
Differences Between STM and LTM
- Coding: STM primarily uses acoustic (sound-based) coding, while LTM primarily uses semantic (meaning-based) coding.
- Capacity: STM has a limited capacity (5-9 items), while LTM has a potentially unlimited capacity.
- Duration: STM holds information for a short duration (seconds), while LTM holds information for a longer duration (potentially lifetime).
- Maintenance rehearsal keeps information in STM longer; elaborative rehearsal moves information to LTM.
Neuropsychological Evidence
- Brain damage studies show that different brain areas are associated with different types of memory and can support specific memory tasks. Pre-frontal cortex is important for working memory.
