چکیده
We have suggested that the Remote Distractor Effect (RDE), the elevation of average saccadic reaction time (SRT) induced by a task-irrelevant distractor, is a statistical consequence of a characteristic reshaping of the SRT distribution known as Saccadic Inhibition (SI) (Buoncore & McIntosh, 2008). In a recent paper, Walker and Benson (2013) argue against this idea, and claim that the RDE and SI are partly dissociable. Here, we examine this claim, taking the opportunity to clarify potential ambiguities about how SI affects average SRT, and how the presence of SI can be inferred from SRT distributions. We highlight what we consider to be the most interesting aspects of Walker and Benson's data, and suggest that a more flexible and nuanced view of SI can account for them. In considering the relation between SI and the RDE, we conclude that the RDE may no longer be a useful concept for eye movement researchers.

Saccadic inhibition can cause the remote distractor effect, but the remote distractor effect may not be a useful concept.
We have suggested that the remote distractor effect (RDE), the elevation of average saccadic reaction time (SRT) induced by a task-irrelevant distractor, may be explained as a statistical consequence of a characteristic reshaping of the SRT distribution known as saccadic inhibition (SI; Buonocore & McIntosh, 2008). In a recent paper, Walker and Benson (2013) argue against this idea and claim th...
متن کاملEffects of stimulus contrast and temporal delays in saccadic distraction
In a recent study, we observed that saccadic distraction (i.e., the remote distractor effect, RDE) was reduced when target and distractor were displayed at unequal contrast [Born, S., & Kerzel, D. (2008). Influence of target and distractor contrast on the remote distractor effect. Vision Research, 48(28), 2805-2816]. We hypothesized that arrival times explain the RDE modulation: With equal cont...
متن کاملSaccadic distractor effects: the remote distractor effect (RDE) and saccadic inhibition (SI): A response to McIntosh and Buonocore (2014).
We (Walker & Benson, 2013) reported studies in which the spatial effects of distractors on the remote distractor effect (RDE) and saccadic inhibition (SI) were examined. Distractors remote from the target increased mean latency and the skew of the distractor-related distributions, without the presence of dips that are regarded as the hallmark of SI. We further showed that early onset distractor...

متن کاملInfluence of target and distractor contrast on the remote distractor effect
In the absence of distractors, saccadic latencies are influenced by target characteristics such as contrast. The same characteristics were expected to influence the remote distractor effect (RDE) when varied in the distractor. We conducted three experiments in which we varied target and distractor contrast orthogonally. The results show that the RDE is not so much modulated by distractor contra...
