PSY270H5 Lecture Notes - Lecture 4: Attentional Blink, Peanut Butter
Document Summary
Faster at detecting target at cued location than neutral- process facilitation. Filtering out of neutral information: when cue is invalid. Still a bit faster at detecting target at the cued location even though it is counterproductive- involuntary attentional capture. Attention is automatically allocated to something salient. Overt vs. convert attention: overt visual attention: directed to where you look at. Can be tracked by eye movements: convert visual attention: can be directed to where you are not looking at. Can be tracked by neural activities (eg. eeg, erp, fmri) Object-based attention and its erp correlate: object-based attention: attention can also be allocated to objects instead of space, multiple objects experiment, difference wave= contralateral amplitude- ipsilateral amplitude. Is there a temporal limitation in information processing: potter"s rapid serial visual presentation (1976) Try to remember all of the pictures, and test recognition memory for one picture. Detect one target picture based on actual image.
