Study Notes
Working Memory and Executive Functioning
- Working memory is an alternative approach to studying executive functions.
- Executive processes regulate thought and action, closely linked to frontal lobes.
- Neuropsychological tests (e.g., Wisconsin Card Sort) are often used to assess executive processes.
- These tests are considered "impure" due to their complexity and examining multiple cognitive functions.
- Miyake et al. (2000) identified three independent executive processes: updating, shifting, and inhibition.
- Updating involves constantly monitoring and adjusting working memory contents.
- Shifting refers to flexibly switching between tasks or mental sets.
- Inhibition is overriding dominant responses.
Wisconsin Card Sort Task
- The Wisconsin Card Sort Task (WCST) is a test used to assess executive functions.
- It involves sorting cards based on shape, color, or number.
- The task requires individuals to adjust their strategy as rules change.
Miyake & Friedman (2012) - Task Examples
- Updating: Letter Memory Task (remembering the last 3 letters)
- Shifting: Color-Shape Task (classify by color or shape)
- Inhibition: Antisaccade Task (report the opposite direction of an arrow)
Friedman et al. (2011) - Key Findings
- A common executive function (EF) factor exists; updating, shifting, and inhibition are related.
- These functions also have independent contributions to cognitive tasks.
Just & Carpenter (1992) - Capacity Theory of Comprehension
- A valid measure of working memory considers storage and processing demands.
- Working memory is an active workspace, not just passive storage.
- Both storage and processing occur concurrently.
- A common resource, activation, mediates processing and storage.
- Individual differences (activation) affects performance in tasks requiring both.
Simple Span Tasks
- Focus on short-term memory, remembering sequences in order.
- Examples: Digit Span (numbers), Word Span (words).
- Do not involve significant processing demands.
Complex Span Tasks
- Involve simultaneous storage and processing.
- Examples: Reading Span (remembering last words in sentences), Operation Span (solving math and remembering words).
Simple Span vs. Complex Span Tasks - Key Differences
- Simple Span: Focuses on storage; Complex Span: Involves storage and processing
- Simple Span: Less demanding; Complex Span: More demanding
- Complex Span correlates more strongly with higher cognitive abilities.
Daneman & Merikle (1996) - Key Findings
- Complex span tasks are better predictors of language comprehension than simple span tasks.
Sanchez & Wiley (2006) - Key Findings
- Complex span tasks are valuable predictors for real-world tasks (learning from complex texts).
- Working memory capacity is crucial for learning and comprehension in complex texts.
- Different types of illustrations (non-illustrated, conceptual, seductive) affect performance, particularly in low working memory capacity individuals.
Kane et al. (2007) - Mind Wandering Study
- Examined how working memory capacity (WMC) relates to mind wandering during everyday activities.
- Higher WMC individuals were better at maintaining focus during challenging tasks.
Cowan (2010) - Working Memory
- Working memory is an activated subset of long-term memory (LTM).
- Information actively used is part of LTM.
- A limited focus of attention (about 3-4 items) exists within the activated LTM portion.
Ranganath et al. (2003) - Neuroscience Study
- Study investigated the neural mechanisms of working memory and long-term memory.
- Overlapping regions in the prefrontal cortex support both WM and LTM tasks.
- Results challenge the idea that WM and LTM are entirely distinct.
