The locus and modulation of the location negative priming effect

Area of Science:

• Cognitive Psychology
• Human Information Processing
• Perceptual Psychology

Background:

• The negative priming (NP) effect demonstrates inhibitory mechanisms in selective attention.
• Location negative priming specifically refers to slower responses to targets at recently relevant distractor locations.
• The underlying cause of location NP, whether location-based or response-based inhibition, remains debated.

Purpose of the Study:

• To investigate the locus of the location negative priming (NP) effect.
• To determine if location NP arises from distractor location reuse or distractor response execution.
• To examine the role of response cues in modulating location NP.

Main Methods:

• Employed a location negative priming procedure with a many-to-one (many:1) location-to-response mapping.
• Included trials with and without response cues to assess interference.
• Analyzed response initiation times for distractor-turned-target versus new responses.

Main Results:

• Distractor-turned-target responses were initiated more slowly than new responses, supporting a response locus.
• Valid response cues significantly reduced distractor response interference and the location NP effect.
• Evidence against a stimulus-response (S-R) compatibility issue within the many:1 paradigm was found.

Conclusions:

• The location negative priming effect is primarily driven by response-based inhibition, not solely by distractor location reuse.
• Response interference plays a critical role in the observed slowing of responses in ignored-repetition trials.
• Response cues can effectively mitigate the impact of distractor response interference on performance.
