- These are the complete datasets for Experiment 1-3 of the manuscript currently titled "Diagnostic parts are not exclusive in the search template for real-world object categories" by Marcel Wurth and Reshanne R. Reeder. This study contains a direct replication of Experiment 4 from Reeder & Peelen (2013), and two follow-up experiments. In each experiment, subjects were cued to search for cars and people in natural scenes (75% of trials) either presented to the left and right of a central fixation (Exp.1) or above and below fixation (Exp.2&3). On a subset of trials (25% of trials), subjects were instructed only to respond to the location of a black dot that appeared on the left or right of fixation. Capture stimuli (the silhouettes) appeared prior to the dot, but subjects were told to ignore these to the best of their ability. One car and one person silhouette appeared on each capture trial and appeared an equal number of times on the left and right of fixation. The location of the target-matching silhouette was tied to the same side of fixation as the dot-probe on half of trials (consistent trials). The target-matching silhouette appeared on the opposite side of fixation from the dot-probe on the other half of trials (inconsistent trials). In Exp.1&2, capture stimuli were either both whole silhouettes or both single silhouette parts, with these trials randomly mixed within a block. In Exp.3, capture stimuli were either both whole silhouettes or both collections of silhouette parts. Our main goal was to find out if subjects performed better on consistent dot-probe trials than on inconsistent dot-probe trials. A consistent trial is defined as a trial on which the cue-matching silhouette appears on the same side of fixation as the dot-probe. An inconsistent trial is a trial on which the cue-matching silhouette appears on the other side of fixation from the dot-probe. We calculated RT from the onset of the dot-probe. Only correct trials were input into the RT analysis. Attention capture was defined as faster RT on consistent trials compared to inconsistent trials. Reeder, R. R., & Peelen, M. V. (2013).
