Identity negative priming: a phenomenon of perception, recognition or selection?

Area of Science:

• Cognitive Psychology
• Experimental Psychology

Background:

• Negative priming (NP) and positive priming (PP) are key phenomena in attention research.
• Previous studies often confound NP with perceptual similarity, hindering understanding of its underlying mechanisms.

Purpose of the Study:

• To differentiate the cognitive stages of NP and PP.
• To investigate whether NP originates in perception, recognition, or selection.
• To resolve confounding factors in existing NP research using a novel paradigm.

Main Methods:

• A color-switch paradigm was employed across three identity negative priming experiments.
• Verbal naming response was used to measure priming effects.
• Experiment 1 used fixed target colors, Experiment 2 used trial-wise color cues, and Experiment 3 separated stimulus recognition from cue presentation.

Main Results:

• No differential priming effects were observed based on fixed target color (Experiment 1).
• Perceptual similarity was resolved; coinciding colors showed priming, while color switches affected PP but not NP in role-reversal trials (Experiment 2).
• Recognition was faster in all priming conditions compared to controls when cues were presented post-recognition (Experiment 3).

Conclusions:

• Positive priming (PP) is significantly influenced by perceptual factors.
• Negative priming (NP) emerges during the selection stage of information processing.
• NP and PP are distinct processes and cannot be explained by a single underlying mechanism.
