Negative identity priming is contingent on stimulus repetition

Summary
Negative identity priming effects depend on how often stimuli are repeated. Repeated stimuli, especially as targets, lead to negative priming, supporting activation-based models.
Area of Science:
- Cognitive Psychology
- Experimental Psychology
- Memory and Attention Studies
Background:
- Negative priming is a phenomenon where previously encountered stimuli are responded to more slowly.
- The role of stimulus repetition in modulating negative priming effects remains an area of investigation.
- Existing models, such as activation-based and episodic retrieval models, offer different explanations for negative priming.
Purpose of the Study:
- To investigate the influence of stimulus repetition on negative identity priming.
- To determine whether repetition as a target or distractor is critical for negative priming.
- To evaluate the generalizability of repetition effects across different experimental paradigms and materials.
Main Methods:
- Conducted five experiments manipulating stimulus repetition in ignored repetition conditions.
- Utilized both naming and same-different paradigms with verbal and pictorial stimuli.
- Employed familiar and unfamiliar stimuli with vocal and manual response modes.
Main Results:
- Negative identity priming was contingent on stimulus repetition.
- Priming initially positive, became negative with increased stimulus repetitions.
- Repetition as a target, not a distractor, was critical for negative priming.
- Repetition effects were general across paradigms, materials, and response types.
- Replication of prior findings on novel shapes was not achieved.
Conclusions:
- Findings support activation-based models of negative priming.
- Results challenge the episodic retrieval model of negative priming.
- Stimulus repetition is a key factor influencing negative priming magnitude and direction.
