Understanding the Differences Between Overt and Covert Attention

Play an AI-generated podcast conversation about this lesson

Which type of attention involves eye gaze matching focus of attention?

Overt attention (correct)

Selective attention

Covert attention

Divided attention

How did participants in the Posner et al. (1980) study maintain their focus of attention?

They looked for cues within the visual field.

They were instructed to follow the movement of a visual target.

They moved their eyes to match their focus of attention.

They kept their eyes focused on a fixation cross without moving them. (correct)

What was the effect of a valid cue on participants' reaction times (RTs) in the Posner et al. (1980) study?

RTs were faster than when no cue was given. (correct)

RTs were slower than when no cue was given.

RTs were unaffected by the cue.

RTs became unpredictable and varied widely.

What is the reason for cued targets having a disadvantage after 300ms, as mentioned in the content?

c. Cued targets have a disadvantage because your attention does want to go back to somewhere a target didn't appear Signup and view all the answers
