Study Notes
Memory
- Memory: processes involved in retaining, retrieving, and using information, including stimuli, images, events, ideas, and skills, after the original information is no longer present.
- Memory is active any time a past experience has an impact on how we think or behave in the present or future.
The Modal Model of Memory
- Proposed by Atkinson and Shiffrin (1968)
- Describes three types of memory:
- Sensory Memory
- Short-term Memory
- Long-term Memory
- Control processes are active processes that can be controlled by the person
- Rehearsal
- Strategies to enhance memorability
- Strategies for focusing attention
Sensory Memory
- Brief retention of sensory stimulation.
- Holds a large amount of information for a short amount of time.
- Information decays quickly.
- Processes information initially, collecting and holding it for initial processing.
- Sensory memory fills in the gaps in our perception.
- Persistence of vision is the retention of light perception
- Example: the trail of light left by a sparkler
Sperling's Sensory Memory Experiment
- Sperling (1960) used an array of letters to test sensory memory capacity and duration.
- Letters were flashed quickly for a brief period (50/1000 of a second).
- Participants were asked to recall the letters.
- Whole report method: recall as many letters as possible.
- Average of 4.5 out of 12 letters (37.5% accuracy).
- Partial report method: heard a tone indicating which row of letters to recall.
- Average of 3.3 out of 4 letters (82% accuracy).
- Accurate for all rows.
- Delayed partial report method: tone was presented after the letters were extinguished.
- Performance decreased rapidly with delayed timing.
- Whole report method: recall as many letters as possible.
Sensory Memory: Types
- Iconic memory is the brief sensory memory of what we see.
- Responsible for persistence of vision.
- Echoic memory is the brief sensory memory of what we hear.
- Responsible for persistence of sound.
Short-Term Memory vs. Working Memory
- Short-term memory (STM) is responsible for holding a small amount of information for a brief period of time
- Working memory (WM) is responsible for the processing and manipulation of information that occurs during complex cognition
Modal Model of Memory
- Atkinson and Shiffrin (1968) proposed a model with three types of memory
- Sensory Memory: Holds all incoming information for a short period (seconds to fractions of a second)
- Short-Term Memory: Holds 5-9 items for 15-30 seconds
- Long-Term Memory: Holds large amounts of information for years
Sensory Memory
- Sensory memory is the brief retention of sensory information
- It has a large capacity but decays rapidly
- Iconic memory is visual sensory memory, responsible for persistence of vision
- Echoic memory is auditory sensory memory, responsible for persistence of sound
Short-Term Memory
- Peterson & Peterson (1959) showed rapid decay of STM when rehearsal is prevented
- Capacity of STM is about 5-9 items
- Chunking is a strategy to increase STM capacity by grouping smaller units into larger meaningful units
Working Memory
- Baddeley & Hitch (1974) proposed a model of WM with multiple components that function separately
- Phonological Loop: Holds verbal and auditory information
- Articulatory Rehearsal Process: Maintains information by repeating it to prevent decay
- Visuospatial Sketchpad: Holds visual and spatial information
- Involved in visual imagery and mental rotation tasks
- Central Executive: Attention controller
- Focuses, divides, and switches attention
- Inhibits irrelevant information
- Controls suppression of irrelevant information
- Episodic Buffer: Back-up store that communicates with WM and LTM
- Holds information longer and has greater capacity than other WM components
- Phonological Loop: Holds verbal and auditory information
Brain and Working Memory
- The frontal cortex plays a role in WM and attention
- Prefrontal cortex processes incoming visual and auditory information
- Monkeys without a prefrontal cortex struggle with tasks that require WM (e.g., delayed-response tasks)
