Where has all the inhibition gone? Insights from electrophysiological measures into negative priming without probe distractors.

چکیده
Responses to probe targets that have been distractors in a prime display are slower than responses to unrepeated stimuli, a finding labeled negative priming (NP). However, without probe distractors the NP effect usually diminishes. The present study is the first to investigate ERP correlates of NP without probe distractors to shed light on the processes underlying NP. Based on existing findings in the field, we analyzed two ERP correlates that have been associated with the visual NP effect so far, namely the N200 and the P300. As expected, no behavioral NP effect as well as no N200 modulation emerged. However, the P300 component was enhanced when a prime distractor was repeated as the probe target. This effect is interpreted as reflecting automatic retrieval of the prime episode occurring independently of the presence of probe distractors.

Object-based perceptual grouping affects negative priming.
In 5 experiments the authors examine the role of object-based grouping on negative priming. The experiments used a letter-matching task with multiple letters presented in temporally separated prime and probe displays. On mismatch trials, distractor letters in primes were repeated as targets in probes, or distractor and target letters were completely different. Negative priming was shown by slow...
متن کاملThreat processing in obsessive-compulsive disorder: evidence from a modified negative priming task.
Individuals with obsessive-compulsive disorder (OCD) often experience intrusive thoughts. These intrusions may be due to biases in information processing mechanisms, including attention, memory, and learning. To examine this hypothesis, we presented a modified negative priming (NP) paradigm with idiographically selected words to 19 individuals with OCD (OCs) and 19 matched non-anxious control p...
متن کاملSemantic priming in the prime task effect: evidence of automatic semantic processing of distractors.
The automaticity of the semantic processing of words has been questioned because of the reduction of semantic priming when the prime word is processed nonsemantically--for example, in letter search (the prime task effect). In two experiments, prime distractor words produced semantic priming in a subsequent lexical decision task, but with the direction of priming (positive or negative) depending...

Inhibition of return and negative priming by persons with and without mental retardation.
Persons with and without mental retardation who were matched on CA took part in three tasks: an inhibition of return task, a location negative-priming task, and an identity negative-priming task. Having participants perform all three tasks allowed us to correlate performance among the tasks and assess the various relationships among performance measures on negative priming and inhibition of ret...
