Behavioral data support the model-derived prediction of attraction biases. A: schematic illustration of the paradigm used in the behavioral experiment. B: illustration of the sorting of trials according to relative positions of the items. In one case, items were far from each other (far trials, framed in black). In the other case, the target item was presented close to another item and was displaced away from its neighbor during probing (outward trials, framed in green). C: fraction of errors averaged over participants (n = 8) in 48 trials of each trial type (delay/no delay and far/outward). Data were analyzed with a probit model. There was a significant interaction between delay and trial type. For no-delay trials there was no difference between the fraction of errors for far and outward trials, while there was a significant difference for delay trials. *Significant differences. Error bars indicate SE. D: schematic illustration of the mechanism thought to underlie the decrease in errors for outward trials compared with far trials. Bell-shaped curves represent the probability distribution of the remembered locations. The probed item defines an area under the probability function. This area is the probability of incorrectly judging the direction of displacement of the probe and is larger for far than outward trials (a2 < a1). The distance between location of the item and the location of the probe is larger for outward trials (d1 < d2). Hence, the probability of a correct response in outward trials is larger than in far trials, as observed experimentally. E: illustration of another sorting of trials, all containing the probed item in the vicinity of another item. Trials were sorted according to the clockwise or counterclockwise location of the probed item relative to the neighboring item. F: psychometric curves for clockwise and counterclockwise trials were horizontally displaced in relation to each other. Curves resulted from a probit model fit to data from all participants (n = 8). The results of C and F are consistent with the prediction of attraction biases.
