AbstractWe challenge the central idea proposed in Hulleman & Olivers (H&O) by arguing that the “item” is still useful for understanding visual search and for developing new theoretical frameworks. The “item” is a flexible unit that represents not only an individual object, but also a bundle of objects that are grouped based on prior knowledge. Uncovering how the “item” is represented based on prior knowledge is essential for advancing theories of visual search.

Distinctive Features

An experiment is reported which demonstrates that the features used to detect a character in arrays of similar forms are a function of the stimulus context in which the target is embedded. With the use of blocked and randomised design it was shown that prior knowledge of the background aided search when the feature which was relevant for one background was irrelevant for another, but no significant effect of prior knowledge was obtained when the same feature was useful for the backgrounds.

Search Training

Despite the conventional wisdom that it is more difficult to find a target among similar distractors, this study demonstrates that the advantage of searching for a target among dissimilar distractors is short-lived, and that high target-to-distractor (TD) similarity during visual search training can have beneficial effects for learning. Participants with no prior knowledge of Chinese performed 12 hour-long sessions over 4 weeks, where they had to find a briefly presented target character among a set of distractors. At the beginning of the experiment, high TD similarity hurt performance, but the effect reversed during the first session and remained positive throughout the remaining sessions. This effect was due primarily to reducing false alarms on trials in which the target was absent from the search display. In addition, making an error on a trial with a specific character was associated with slower visual search RTs on the subsequent repetition of the character, suggesting that participants paid more attention in encoding the characters after false alarms. Finally, the benefit of high TD similarity during visual search training transferred to a subsequent n-back working memory task. These results suggest that greater discrimination difficulty likely induces stronger and more distinct representations of each character.
