Nonattentional effects of nonpredictive central cues

Area of Science:

• Cognitive psychology
• Neuroscience
• Human attention studies

Background:

• Reflexive attention shifts are known to be triggered by nonpredictive cues like gaze, hand, and arrows.
• The influence of such cues on decision criteria, particularly in tasks requiring response inhibition, remains less understood.

Purpose of the Study:

• To investigate whether nonpredictive central gaze, hand, and arrow cues affect the decision criterion in a go/no-go task.
• To determine if these cues influence response bias beyond modulating attentional processes.

Main Methods:

• Participants performed a go/no-go task with nonpredictive central gaze, hand, arrow, or peripheral cues.
• Cues were directed either toward or away from the impending target location.
• Response times and error rates (false alarms) were analyzed based on cue direction.

Main Results:

• Nonpredictive central gaze and hand cues pointing toward the target led to faster responses and more false alarms compared to cues pointing away.
• A similar pattern was observed with nonpredictive arrow cues.
• Nonpredictive peripheral cues did not produce this effect.

Conclusions:

• Nonpredictive central cues (gaze, hand) and arrow cues appear to bias decision-making processes in a go/no-go task.
• These findings suggest that nonpredictive cues can influence both attention and response criteria, challenging a purely attentional account.
