- Case studies around the Working Memory Model
- The central executive
- D'esposito et al (1995)
- The visuo-spatial sketchpad
- Klauer & Zhao(2004) found more interference between two visual tasks than a visual and spatial tasks.
- This was because one task was using the PL and the other the VSS.
- Gathercole & Baddeley (1993)
- Klauer & Zhao(2004) found more interference between two visual tasks than a visual and spatial tasks.
- Shallice & Warringtion (1974)
- Investigated a patient named KF who had suffered brain damage in a motorcycle accident.
- The episodic buffer
- Prabhakaran et al (2000)
- The phonological loop
- Trojani & Grossi (1995)
- Conducted a case study of a patient who had brain damage affecting the PL but not the VSS.
- Trojani & Grossi (1995)
- The central executive
- This suggests that the PFC is involved in CE.
- Used fMRI and found out that the pre-frontal cortex is activated when verbal & spatial tasks are performed.
- This suggests that the PL and VSS are separate systems.
- Participants recalled shorter words in serial order.
- Baddeley et al(1975) investigated the 'word length effect'.
- Concluded that the capacity of the PL is set by duration of words and not the number of words.
- This adds support to the separate VC & IS components.
- Found that participants had problems simultaneousl tracking a moving point of light and performing a spatial task.
- But greater posterior activation for non-combined information.
- Used fMRI scans and found greater right-frontal brain activation for both verbal & spatial information.
- This provides biological support that the EB allows temporary storage of integrated information.
- Using a bunch of psychometric tests they concluded his STM problems were greater for auditory information than visual.
- Investigated a patient named KF who had suffered brain damage in a motorcycle accident.
- Suggests his damage was restricted to the PL.
- His case suggests that the STM and LTM are separate stores.
