Study Notes
- Study notes for Working Memory P2 + damage to working memory
Sergio Della Sala et al's 1999 Study
- This study explored mental rotation and working memory.
- Participants viewed a test pattern resembling a crossword for 3 seconds.
- They were then asked to replicate the pattern from memory.
- Test patterns ranged from a 2x2 matrix (4 squares) to a 5x6 matrix (30 squares).
- 1/2 of the squares in the matrices were shaded.
- Participants accurately completed patterns averaging 9 shaded squares before making errors.
- Higher results compared to Luck and Vogel's STM experiment were likely due to visual chunking.
Lee Brooks' 1968 Experiment
- Demonstrated that overloading the visuospatial sketchpad disrupts visual memory performance.
- Participants traced the outline of an imaginary letter "F," noting outside and inside corners while simultaneously pointing in the same direction.
- A second condition involved tracing the letter "F" in their mind's eye.
- Simultaneously participants stated out loud whether each corner was "in" or "out."
- The talking condition proved easier due to the pointing condition overloading the visuospatial sketchpad.
Central Executive
- The control center of the working memory system.
- Coordinates how information is used by the phonological loop and visuospatial sketchpad.
- Baddeley describes it as an attention controller.
- Determines how attention is focused on a specific task.
- Determines how attention is divided between two tasks.
- Determines how attention is switched between tasks, thus it is part of executive attention.
Brain Damage and Frontal Lobe
- Studies show the frontal lobe plays a key role in working memory.
- Frontal lobe damage causes problems controlling attention.
- Perseveration is a typical behavior seen in patients with frontal lobe damage.
- Perseveration invloves repeatedly performing the same action or thought, even if it doesn't achieve the desired goal.
- Individuals with frontal lobe damage may fail to respond correctly to changes in task directions.
- This is due to an impaired central executive's failure to adequately control attention.
Baddeley's Episodic Buffer (2009)
- A work-in-progress component added to the working memory model.
- Helps increase capacity to hold information within working memory by working directly with long-term memory, acting as some kind of interchange.
WM, the Brain, and Prefrontal Cortex (PFC)
- Research has been dominated by studies on the prefrontal cortex.
- A significant case is that of Phineas Gage and his tamping rod accident on Sept 13, 1848.
- It's unclear whether reports of Gage's personality prior to the accident were accurate.
- After the accident, he appeared to demonstrate low impulse control, poor ability to plan, and poor social skills.
- Gage's case linked frontal lobe areas to mental functions concerning personality and planning.
Goldman-Rakic's Delayed Response Task (1990 & 1992)
- Experiments studied the effects of removing the prefrontal cortex in monkeys.
- Monkeys were presented with two food wells, only one containing food.
- The wells were covered, and a screen lowered to block the monkeys' view for a period.
- When the screen was raised, the monkeys had to select the correct (covered) food well.
- Monkeys with their PFC removed selected the correct food well only about 50% of the time.
- This is equivalent to selecting the food randomly (by chance).
- Monkey experiments provide evidence that the PFC is important for holding information for brief periods.
