Confidence for intrusion errors during the attentional blink depends on target-defining features

Area of Science:

• Cognitive Psychology
• Neuroscience
• Perception

Background:

• The attentional blink (AB) is a deficit in identifying a second target stimulus when it closely follows a first.
• Previous research suggests AB performance is stimulus-nonspecific.
• However, error patterns and confidence in errors may reveal underlying attentional or perceptual mechanisms.

Purpose of the Study:

• To compare error patterns and confidence in errors during the AB.
• To investigate if target-defining features (letter color vs. annulus color/presence) influence these error characteristics.

Main Methods:

• Three experiments were conducted comparing error patterns and confidence.
• Target stimuli were defined by letter color, annulus color, or annulus presence.
• Participants responded to targets, and their error patterns and confidence ratings were analyzed.

Main Results:

• When targets were defined by annuli, participants showed similar confidence in both correct responses and post-target errors.
• This pattern was not observed when targets were defined by letter color.
• Experiment 3 suggested a time-dependency in error patterns and confidence when using annulus color as the target cue.

Conclusions:

• Error patterns and confidence during the attentional blink are not stimulus-nonspecific.
• The findings suggest different attentional or perceptual mechanisms may underlie the AB depending on target-defining features.
• Further research is needed to understand the nature of AB errors and their underlying mechanisms.
