AbstractFinding relevant objects through vision, or visual search, is a crucial function that has received considerable attention in the literature. After decades of research, data suggest that visual fixations are more crucial to understanding how visual search works than are the attributes of stimuli. This idea receives further support from the field of haptic search.

Efficiency of search often comes with experience. We explored search processes during a highly dynamic and complex task: rock climbing. In general, we found similarities between expert and non-expert climbers regarding their visual search and differences in their tactile search. Analyses determined that experts and non-experts did not differ in their visual fixations toward areas of interest (AOIs), but differed in their mean fixation times depending on the terrain. Experts performed fewer investigative touches than non-experts, suggesting that experts might have climbed faster due to their reliance on visual rather than tactile cues. These findings support the theory of information foraging in a dynamic environment by suggesting that non-experts used tactile search to acquire information rather than relying on visual search.

Ball games are characterized by perceptual uncertainty and time-pressure. Of interest is the visual-search pattern carried out when these characteristics change. This is the case in table-tennis situations when comparing a drill situation, when one kind of stroke is constantly repeated, and a match situation, when the stroke is more often unpredictable. We analysed, during play, the visual-search pattern of five expert table tennis players to examine the effect of uncertainty on visual behavior. Direction of gaze was recorded by a video-oculographic recorder (NAC Eye Mark Recorder IV). Analysis showed that (i) visual fixations towards opponent player were only systematic in a match, contrary to drill where they occurred less frequently. (ii) Whatever the situation, only the first part of the ball's trajectory was visually tracked. This occurred immediately after the opponent's release of the ball. Nevertheless, visual tracking was more frequent and of longer duration in a match. (iii) Analysis of motor behavior showed that the duration of the movement preparation was longer in a match while the duration of the execution phase was unchanged.

The visual search strategies employed by gymnastic coaches with different levels of expertise were investigated. Expert ( n = 3) and novice coaches ( n = 3) watched 9 video sequences of 3 gymnastic techniques and were required to highlight errors in performance. Visual search patterns were monitored by an ASL-5000SE eye-tracking system during observation. Expert participants showed longer and fewer visual fixations than the novice group.

Under incidental learning conditions, spatial layouts can be acquired implicitly and facilitate visual search (contextual-cueing effect). We examined whether the contextual-cueing effect is specific to the visual modality or transfers to the haptic modality. The participants performed 320 (experiment 1) or 192 (experiment 2) visual search trials based on a typical contextual-cueing paradigm, followed by haptic search trials in which half of the trials had layouts used in the previous visual search trials. The visual contextual-cueing effect was obtained in the learning phase. More importantly, the effect was transferred from visual to haptic searches; there was greater facilitation of haptic search trials when the spatial layout was the same as in the previous visual search trials, compared with trials in which the spatial layout differed from those in the visual search. This suggests the commonality of spatial memory to allocate focused attention in both visual and haptic modalities.

Computer use generally requires manual interaction with human-computer interfaces. In this experiment, we studied the influence of manual response preparation on co-occurring shifts of attention to information on a computer screen. The participants were to carry out a visual search task on a computer screen while simultaneously preparing to reach for either a proximal or distal switch on a horizontal device, with either their right or left hand. The response properties were not predictive of the target’s spatial position. The results mainly showed that the preparation of a manual response influenced visual search: (1) The visual target whose location was congruent with the goal of the prepared response was found faster; (2) the visual target whose location was congruent with the laterality of the response hand was found faster; (3) these effects have a cumulative influence on visual search performance; (4) the magnitude of the influence of the response goal on visual search is marginally negatively correlated with the rapidity of response execution. These results are discussed in the general framework of structural coupling between perception and motor planning.

This study compared individuals with pairs in a scientific problem-solving task. Participants interacted with a virtual psychological laboratory called Virtue to reason about a visual search theory. To this end, they created hypotheses, designed experiments, and analyzed and interpreted the results of their experiments in order to discover which of five possible factors affected the visual search process. Before and after their interaction with Virtue, participants took a test measuring theoretical and methodological knowledge. In addition, process data reflecting participants’ experimental activities and verbal data were collected. The results showed a significant but equal increase in knowledge for both groups. We found differences between individuals and pairs in the evaluation of hypotheses in the process data, and in descriptive and explanatory statements in the verbal data. Interacting with Virtue helped all students improve their domain-specific and domain-general psychological knowledge.

When distractor configurations are repeated over time, visual search becomes more efficient, even if participants are unaware of the repetition. This contextual cueing is a form of incidental, implicit learning. One might therefore expect that contextual cueing does not (or only minimally) rely on working memory resources. This, however, is debated in the literature. We investigated contextual cueing under either a visuospatial or a nonspatial (color) visual working memory load. We found that contextual cueing was disrupted by the concurrent visuospatial, but not by the color working memory load. A control experiment ruled out that unspecific attentional factors of the dual-task situation disrupted contextual cueing. Visuospatial working memory may be needed to match current display items with long-term memory traces of previously learned displays.
