ABSTRACT
Purpose: This study investigated 2 suppression mechanisms—(a) resistance to distracter interference and (b) inhibition of a prepotent response—in preschool children with specific language impairment (SLI) and their typically developing peers. Method: Twenty-two preschool children with SLI and 22 typically developing controls participated in this study. The resistance to distracter interference task involved suppressing distracters (nonverbal auditory, linguistic, and visual) that were external and irrelevant to the task goal. Inhibition was assessed using a stop-signal paradigm to evaluate the ability to suppress a prepotent, conflicting response. Results: The children with SLI exhibited decreased resistance to distracter interference regardless of distracter modality and poor inhibitory control relative to their typically developing peers. Conclusion: These results identify suppression weaknesses in preschool-age children with SLI. Specifically, children with this disorder exhibited difficulty suppressing both irrelevant and contradictory information.

    Simultaneous masking refers to the impairment of performance on a visual target by simultaneously presented flankers. Whereas the spatial aspects of simultaneous masking have been studied extensively, the time course of these spatial influences is much less well understood. We here measure...

    In 3 experiments, the role of item strength in the retrieval-induced forgetting paradigm was tested. According to the inhibition theory of forgetting proposed by M. C. Anderson, R. A. Bjork, and E. L. Bjork (1994), retrieval-induced forgetting should be larger for items that are more strongly...

    When a distractor was presented simultaneously with or directly following a target, it produced more interference when it was presented in the same visual hemifield as the target than when it was presented in the opposite visual field. This result is interpreted in terms of biased competition;...

    The substantial distractor interference obtained for small displays when the target appears alone is reduced in large displays when the target is embedded among neutral letters. This finding has been interpreted as reflecting low-load and high-load processing, respectively, thereby supporting...

    Load theory of attention proposes that distractor processing is reduced in tasks with high perceptual load that exhaust attentional capacity within task-relevant processing. In contrast, tasks of low perceptual load leave spare capacity that spills over, resulting in the perception of...

    Loach and Marí-Beffa (Vis Cogn, 10:513–526, 2003) observed that a distractor stimulus, presented immediately after a behaviorally relevant target stimulus, negatively primed a related probe stimulus indicating that the distractor had been inhibited. They argued that “post-target...
