Visual cues help to select a target and attract attention to it. In the present study, a 50-ms exogenous cue was presented to select one of 80 tilted lines, and attention effects at various delays were measured as the time observers needed to identif

In order to investigate the search performance and strategies of nonhuman primates, two macaque monkeys were trained to search for a target template among differently oriented distractors in both free-gaze and fixed-gaze viewing conditions (overt and

Why is it easy to find strawberries and difficult to collect gooseberries or green tomatoes? Why don't we see the tree in the forest but do see the single tree in the garden? Various explanations have been given to account for these phenomena. The pr

It has been proposed that maximum and minimum targets (like the brightest or the least-bright item of a sample) are found by different search processes, the latter but not the former being sensitive to the withdrawal of focal attention. The present s

A target that differs in orientation from neighboring lines and “pops out” has been found to evoke larger responses in cortical V1 cells than lines in the uniform texture surround which do not popout (e.g., Journal of Neurophysiology 67 (1992) 96

To investigate the role of salience in fast visual search, time courses for the detection and identification of salient targets were measured in six subjects, using texture-like line arrays. Single lines were made salient from luminance contrast, mot

Single cell recordings in area V1 of the macaque monkey had suggested that saliency effects from orientation contrast might be delayed compared to the representation of other stimulus properties. This conjecture was tested in three series of experime

The salience of popout targets was measured in regular line arrays as a function of texture density. Test targets (singletons with orientation, motion, or luminance contrast) presented at different raster widths were compared with reference lines (li

Visual search operates in different modes assumed to reflect serial and parallel processing. The basis of this distinction is not yet clear. It is often assumed that serial search involves sequential shifts of focal attention across a scene and that

Neuronal responses to static and moving texture patterns were investigated in the striate cortex of anaesthetized and paralysed adult cats. Texture patterns were composed of a central light bar presented in the excitatory receptive field of a cell an
