Flashcard: Understanding Visual Attention and Search — 18 carte

Selective Attention — definition?

Biases processing to a subset of stimuli.

Posner’s Cueing Method — purpose?

Measures reaction times to assess attention shifts.

Cue Types — examples?

Symbolic (endogenous) and peripheral (exogenous).

SOA Effects — maximum benefit?

150 ms for peripheral, 300 ms for symbolic cues.

Inhibition of Return — meaning?

Reduced attention to recently attended locations at longer SOAs.

Attentional Capture — trigger?

New objects with abrupt onsets automatically attract attention.

Visual Search Tasks — types?

Feature search (efficient) and conjunction search (inefficient).

Binding Problem — challenge?

How features combine into unified objects.

Illusory Conjunctions — cause?

Incorrect feature binding due to lack of focused attention.

RSVP — what?

Rapid presentation of stimuli at a single location.

Repetition Blindness — phenomenon?

Failing to detect repeated items in RSVP sequences.

Attentional Blink — duration?

200–500 ms after first target.

Video Game Effects — impact?

Reduces attentional blink, improving temporal attention.

Feature Search — reaction time?

Fast, unaffected by set size or target presence.

Conjunction Search — reaction time?

Slower, increases with set size and target absence.

Binding Problem — solution?

Attention serially combines features to form objects.

Illusory Conjunctions — example?

Mixing features from different objects in perception.

Attentional Capture — bottom-up or top-down?

Bottom-up, automatic, stimulus-driven process.
