Study Notes
Working Memory and Cognitive Control
- Working memory is a set of processes for storing and manipulating information in short-term memory. It's involved in controlling attention, planning, and problem-solving, and directing encoding and retrieval from long-term memory.
Baddeley and Hitch Model
- This model proposes three components of working memory:
- Phonological loop: processes verbal information using auditory representations (e.g., inner voice). Includes mental rehearsal.
- Visuospatial sketchpad: processes visual and spatial information (mental images).
- Central executive: controls and monitors the other components, transfers information to and from long-term memory, and handles manipulation.
Verbal Working Memory
- Digit span: Measures the longest sequence of items a person can recall in order.
- Phonological similarity effect: errors increase when recalling similar-sounding information.
- Evidence shows verbal information (even visual input like reading) is encoded acoustically.
Spatial Working Memory
- Spatial span tasks assess the ability to remember sequences of locations.
- Verbal and spatial working memory are independent, with different activities relying more on one or the other.
Cognitive Control
- The ability to manipulate working memory, update information, plan, switch tasks, select stimuli, and inhibit responses. Needed for flexibility in activities.
- Automatic processes: require less attention, performed with practice (e.g., habitual behaviors).
- Controlled processes: require attention, slower to execute (e.g., complex tasks).
Natural Variation in Working Memory
- Some individuals might have strong spatial but weak verbal working memory.
The Myth of Learning Styles
- There's no scientific evidence that learning styles (visual, auditory, kinesthetic, etc.) consistently impact learning performance.
Dual Coding Effect
- Memory is enhanced when material is coded both verbally and spatially.
Modality Effect
- Learning is improved when materials use multiple modalities (e.g., visual and auditory).
Stroop Task
- Measures cognitive control: naming the color of ink versus the word printed, incongruent stimuli require more cognitive control to overcome automatic responses.
Cognitive Control and Habits
- Behavior is a balance between controlled and automatic responses.
- Habits are formed through repetition, faster than controlled responses.
Cognitive Control and Goals
- Goals are often less effective at directing behavior if they conflict with well-established habits.
- Cognitive control is necessary to override habitual responses to meet goals.
