What role does attentional load play in the accuracy of visual search tasks?

a: Higher attentional load improves accuracy by focusing perception. Explanation

Explanation

b: Lower attentional load increases the risk of false alarms. Explanation

Explanation

c: High attentional load can reduce accuracy due to divided attention. Explanation

Explanation

d: Attentional load does not influence search performance. Explanation

Explanation

How does visual crowding affect target detection in peripheral vision?

a: It improves detection by enhancing contrast. Explanation

Explanation

b: It impairs detection by making target features harder to isolate. Explanation

Explanation

c: It has no effect on target perception outside central vision. Explanation

Explanation

d: It increases search speed due to reduced detail. Explanation

Explanation
