Automatic and controlled attention - A3 Flashcards
What is automatic processing? (5)
- fast and parallel, requiring little effort
- no capacity demands
- not conscious
- practice can develop it
- difficult to control
What is controlled processing? (4)
- slower and serial, effortful
- dependent on capacity demands
- dependent on focussed attention
- can be changed quickly
What are the 2 kinds of mapping in Schneider and Shiffrin’s task?
- variable mapping (distractors can be targets in other rounds)
- consistent mapping (distractor and targets separate)
Other than mapping type, what was altered in Schneider and Shiffrin’s task? (3)
- memory set size
- frame size
- frame time
What were the results for consistent mapping in Schneider and Shiffrin’s task? What does this suggest?
- no effect of memory set size
- no effect of frame size
- so capacity demands didn’t affect performance
- suggests that automatic processing is used
What were the results for variable mapping in Schneider and Shiffrin’s task? What does this suggest?
- memory set increase = increased RT
- frame set size increase = increased RT
- so performance was affected by memory load and perceptual load (increased capacity demands)
- suggests controlled processing is used
What happened when participants were trained with new sets of consonants for consistent mapping?
- after 2100 trials performance was independent of memory and frame set sizes - it became automatic
- it took even longer to unlearn this automatic response when the distractors and targets were swapped
What happened when participants were trained with new sets of consonants for variable mapping?
- established in a few trials the new distinction - conscious control
What are the elements involved in Posner’s spatial cueing task? (2)
- peripheral or central cue
- valid or invalid cue
How can the cue presentation be varied in Posner’s spatial cueing task for each participant? (2)
- how informative they are (% of valid trials)
- cue target delay (time between cue and target)
What happens for informative cues in peripheral cueing?
response is fast acting and consistent across cue target delays
validity effect increases up to 100ms then it stays level after that
What happens for informative cues in central cueing?
response is slower acting and consistent across cue target delays
validity effect takes longer to develop (no effect until after 100ms) then it stays at a constant level
What happens for uninformative cues in peripheral cueing?
at short cue target delays, there is a validity effect and people still follow the cues but then with longer gaps, there is an opposite effect and people look away from the cues
What happens for uninformative cues in central cueing?
there appears to be no effect of cueing whatsoever and people ignore it
How do you calculate the validity effect?
invalid RT - valid RT
