Exemplary experimental trial. Distractor repetition with response change trial. a) Experiment 1, prime manipulation. b) Experiment 2, probe manipulation. Responses were made towards the letters identity. Perceptual grouping was manipulated by presenting target and distractor within a single box or in two separate boxes. Note that stimuli are not drawn to scale.

Mean Performance for Experiment 1 and 2. Reaction times (left panels) and error rates (right panels) for a) Experiment 1 and b) Experiment 2. The prime-probe relation reflects the interaction between response relation (repetition vs. change) and distractor relation (repetition vs. change). Response repetition/change trials are abbreviated with RR/RC. Distractor repetition/change trials are abbreviated with DR/DC. Thus, this leads to the four trial types response repetition with distractor repetition (RRDR), response repetition with distractor change (RRDC), response change with distractor repetition (RCDR), and response change with distractor change (RCDC). Note that performance should be impaired in partial repetition trials (RRDC and RCDR) compared to complete repetition or complete change trials (RRDR and RCDC). Error bars indicate within-participant error of the mean (Morey, 2008).

Difference Scores of Individual Binding Effects. Raincloud plots (Allen et al., 2019) for differences of individual binding effects (grouped – ungrouped) for a) Reaction Times and b) Error Rates in Experiment 1 (Prime) and Experiment 2 (Probe). The solid horizontal line in each boxplot represents the median of the distribution, the dashed line represents the mean of the distribution. Upper and lower whiskers extend to the largest/smallest value above/below the respective hinge but at most 1.5 times the interquartile range above and below the third and first quartiles (McGill et al., 1978).
