Working Memory Model To what extent does psychological research support this model of memory?

★ Bottom-up processing- information input to the mind comes via the sensory system ★ Top-down processing- information is processed in the mind via pre-stored information in the memory ★ Attentional control  Automatic level- habits controlled by stimuli in the environment (biking)  Supervisory attentional level- deals with emergencies or new strategies (car coming at you while biking/pothole) Other key terms

PET scans!!!! (They’re baaaaacck!) ★ Identify distinct areas of the brain responsible for different components of working memory. ★ Phonological Loop → frontal & parietal lobes ○Cabeza, 1997 ★ Central Executive → frontal lobes ○Roberts, et al., 1996

Robbins et al., 1996 ●12 chess players, all male, varying abilities ●Asked to sit down in front of a chess game that had already been started & given three minutes to determine the sequence of moves they would take in order to achieve checkmate. ●Asked to record their analysis & decision at the end of the 3 minute period.

Robbins et al., 1996 ●Conditions o Control: press a key on a keypad continuously o Articulatory Loop suppression task: repeat the word see-saw o Visio-spatial Sketchpad suppression task: press keys on a 3x3 keypad in a clockwise motion, not allowed to see the keypad o Central executive suppression: generate a random string of letters to the alphabet aloud ●Results o VSS & CE suppression tasks conditions = significant drop in ability to select correct moves to achieve checkmate!
