Theoretical point: we shouldn’t expect conscious and nonconscious processes to dissociate cleanly, every effect can be influenced by both.
Debner & Jacoby, 1994
A Task
Stem : tab
Completions : table / taboo
Inclusion task : if you see ‘table’ , use this as the completion for ‘tab’
Exclusion task : if you see ‘table’ , DO NOT use this as the completion for ‘tab’
| task | effect of perceptual awareness on performance | effect of nonconscious perception on performance |
| Inclusion (use the word to complete the stem) | facilitates | facilitates |
| Exclusion | facilitates | impairs |
How perceptual awareness should be operationalised according to Dretske, 2006:
we infer lack of awareness from information not being available to the subject as a reason for action
dividing attention : 23 table 37
Key finding: dividing attention impairs perceptual awareness without affecting nonconscious perception
Conclusion: there is perception without awareness
a problem
How perceptual awareness is actually operationalised in Weiskranz et al, 1995:
we infer lack of awareness from the subject’s reports
