Individual differences in Stroop dilution: tests of the attention-capture hypothesis.
Kahneman and Chajczyk (1983) found that naming a colored bar was slowed when a color word was nearby but that this decrement was reduced when a neutral word was also present. This has been referred to as the dilution effect. They accounted for their results with an attention-capture hypothesis. Response time distributions to stimuli that contained a color word and a neutral word within individu...
متن کاملStroop dilution depends on the nature of the color carrier but not on its location.
Stroop dilution is the reduction of the Stroop effect in the presence of a neutral word. It has been attributed to competition for attention between the color word and neutral word, to competition between all stimuli in the visual field, and to perceptual interference. Five experiments tested these accounts. The critical manipulation was whether the color to be named was carried by the color wo...
متن کاملDilution, not load, affects distractor processing.
Lavie and Tsal (1994) proposed that spare attentional capacity is allocated involuntarily to the processing of irrelevant stimuli, thereby enabling interference. Under this view, when task demands increase, spare capacity should decrease and distractor interference should decrease. In support, Lavie and Cox (1997) found that increasing perceptual load by increasing search set size decreased int...
متن کاملInference, Not Dilution in the Dilution Effect
When asked to combine two pieces of evidence, one diagnostic and one non-diagnostic, people show a dilution effect: the addition of non-diagnostic evidence dilutes the overall strength of the evidence. This non-normative effect has been found in a variety of tasks and has been taken as evidence that people inappropriately combine information. We investigated the dilution effect using simple per...
متن کاملEmotional dilution of the Stroop effect: a new tool for assessing attention under emotion.
In order to gauge in a precise fashion the capture of attention by emotional stimuli, we developed a new tool that imports the classic Stroop effect into the realm of emotion. Strooping the typical emotion tasks enabled the derivation of a pure intraitem measure of attention under emotion. The results of two experiments showed that the classic Stroop effects were smaller with emotion than with ...
