Abstract/Results: ABSTRACT:
When searching for a target in a visual scene filled with distractors, the mechanism of inhibition of return prevents revisiting previously attended locations. We proposed a new computational model for the inhibition of return, which is able to examine priority or saliency map in a manner consistent with psychophysical findings. The basic elements of the model are two neural integrators connected with two inhibitory interneurons. The integrators keep the saliency value of the currently attended location in the working memory. The inhibitory inter-neurons modulate a feedforward flow of information between the saliency map and the output map which points to the location of interest. Computer simulations showed that the model is able to read-out the saliency map when the objects are moving or when eye movements are present. Also, it is able to simultaneously select more then one location, even when they are non-contiguous. The model can be considered as a neural implementation of the episodic theory of attention.

Implicit contextual learning in prodromal and early stage Huntington's disease patients
Publication year: 2012

http://journals.cambridge.org/action/displayAbstract?fromPage=online&aid=8631149
Abstract/Results: ABSTRACT:
Huntington's disease (HD) is a genetic neurodegenerative disorder affecting the basal ganglia. These subcortical structures are particularly important for motor functions, response selection and implicit learning. In the current study, we have assessed prodromal and symptomatic HD participants with an implicit contextual learning task that is not based on motor learning, but on a purely visual implicit learning mechanism. We used an implicit contextual learning task in which subjects need to locate a target among several distractors. In half of the trials, the positions of the distractors and target stimuli were repeated. By memorizing this contextual information, attention can be guided faster to the target stimulus. Nine symptomatic HD participants, 16 prodromal HD participants and 22 control subjects were included. We found that the responses of the control subjects were faster for the repeated trials than for the new trials, indicating that their visual search was facilitated when repeated contextual information was present. In contrast, no difference in response times between the repeated and new trials was found for the symptomatic and prodromal HD participants. The results of the current study indicate that both prodromal and symptomatic HD participants are impaired on an implicit contextual learning task.

Abstract/Results: ABSTRACT:
Implicit contextual cueing is a top-down mechanism in which visual search is facilitated by learned contextual features. In the current study we investigate the mechanism underlying this phenomenon. In contrast to previous studies in which spatial information was used as a contextual cue, we used object identity. By memorizing the covariation of objects that are present in our environment, attention can be guided faster to a specific target. We measured eye movements during a visual search task containing repeated object information. We showed that visual search is facilitated by repeated object information and that this reduction in response times is associated with shorter fixation durations. This indicates that by memorizing associations between objects in our environment we can recognize objects faster, thereby facilitating visual search.

Abstract/Results: ABSTRACT:
Implicit contextual cueing refers to a top-down mechanism in which visual search is facilitated by learned contextual features. In the current study we aim to investigate the mechanisms underlying object based implicit contextual cueing by studying eye movements. A visual search task was used in which participants (n = 16) had to locate a target object (abstract line drawing with an opening) among a number of distractors (closed abstract line drawing). In half of the trials the set of objects presented was repeated (Repeated trials), whereas in the other trials a new set of objects was used (New trials). The location of the objects was randomly defined and the objects in the Repeated and New trials were repeated the same number of times. Eye movements were recorded with an iViewX High-speed Eye-Tracker. Subjects located the target faster in the Repeated trials as compared with New trials (p<0.001), indicating that the sets of objects were memorized and search was facilitated. Shorter fixation durations were found for the repeated trials than for the new trials [t (20) = 3.6, p < 0.01]. Furthermore, the Time from Last Fixation until Button Press (TLFBP) was significantly shorter in the repeated than in the new trials [t (20) = 4.6, p = 0.001]. No effect was found for the Number of Fixations and the Saccade Amplitude. This indicates that object recognition is facilitated when object information is used as contextual cue.

Abstract/Results: ABSTRACT:
Implicit context cueing refers to a top-down mechanism in which visual search is facilitated by learned contextual features. To define the underlying mechanism of this phenomenon, previous studies have analyzed the effect of repeated spatial configurations. Although this paradigm has lead to important insights, it can be argued that it has biased our knowledge about implicit context cueing, since spatial context cueing has the unique characteristic that the location of a target is predictable. That is, the target position is fixed in relation to the spatial configuration. When object cues are used, the mechanism that facilitates search is not so obvious. In the current study we aim to investigate the mechanisms underlying object cueing by studying eye movements and we try to define the role of peripheral vision. A visual search task was used in which participants (n = 16) had to locate a target object (abstract line drawing with an opening) among a number of distractors (closed abstract line drawing). In half of the trials the set of objects presented was repeated (Repeated trials), whereas in the other trials a new set of objects was used (New trials). The location of the objects was randomly defined and the objects in the Repeated and New trials were repeated the same number of times. Eye movements were recorded with an iViewX High-speed Eye-Tracker. Subjects located the target faster in the Repeated trials as compared with New trials (p<0.001), indicating that the sets of objects were memorized and search was facilitated. By analyzing the different oculomotor parameters, we found that faster response times are due to a decrease in the number of saccades (p<0.05) and not due to a difference in the saccade amplitude, intersaccadic fixation duration or time between last saccade and button press. The finding that fewer saccades are made is particularly fascinating, since it suggests that fewer objects had to be foveated in order to recognize the target. A possible explanation for this finding is that objects do not need to be foveated for object identification, suggesting an important role for peripheral vision. In order to verify this hypothesis, we performed a second experiment in which participants performed the same search task, but now had to foveate a fixation cross during the entire experiment. Surprisingly, repeated object information facilitated search even when only peripheral vision was used (p < 0.05), thus confirming an important role for peripheral vision in implicit context cueing. When the results of these two studies are taken together, we can conclude that implicit object cueing facilitates object recognition in peripheral vision leading to a more effective search.

Attentional guidance by object context cueing: A study of eye movements

Abstract/Results: ABSTRACT:
Implicit context cueing refers to the facilitation of a visual search by learned contextual features of our environment. In the current study the mechanism underlying this phenomenon is investigated. In contrast to previous studies in which spatial information was used as a contextual cue, we used object identity. The location of the target was not predictable. Eye movement data was recorded for sixteen healthy adults in order to define different oculomotor parameters. Results indicate that the faster response times in trials with a repeated context are due to a decrease in the number of saccades and not due to shorter fixations, saccades or motor responses. In a second study, the role of peripheral vision in implicit context cueing was studied. The same experiment was repeated, but now subjects had to fixate a cross. Unexpectedly, repeated object information facilitated search when only peripheral vision was used. Together, this suggests that fewer saccades are necessary to locate the target, possibly because the target is recognized faster in peripheral vision.

Abstract/Results: ABSTRACT:
Real-world visual searches often contain a variable and unknown number of targets. Such searches present difficult metacognitive challenges, as searchers must decide when to stop looking for additional targets, which results in high miss rates in multiple-target searches. In the study reported here, we quantified human strategies in multiple-target search via an ecological optimal foraging model and investigated whether searchers adapt their strategies to complex target-distribution statistics. Separate groups of individuals searched displays with the number of targets per trial sampled from different geometric distributions but with the same overall target prevalence. As predicted by optimal foraging theory, results showed that individuals searched longer when they expected more targets to be present and adjusted their expectations on-line during each search by taking into account the higher-order, across-trial target distributions. However, compared with modeled ideal observers, participants systematically responded as if the target distribution were more uniform than it was, which suggests that training could improve multiple-target search performance.

Optimal models of human multiple-target visual search

Abstract/Results: ABSTRACT:
Unlike laboratory experiments, real-world visual search can contain multiple targets. Searching for an unknown number of targets creates a unique set of challenges for the observer, and often produces serious errors. We propose a Bayesian optimal foraging model to predict and describe behavior in such search scenarios, and investigate whether people adapt their search strategies based on complex statistics of target distributions. Separate groups searched arrays drawn from three target distributions with the same average number of targets per display, but different target-clustering properties. As predicted, participants searched longer when they expected more targets to remain and adjusted their expectations as searches unfolded, indicating that searchers are sensitive to the target distribution, consistent with both an optimal foraging framework and an ideal Bayesian observer. However, compared to the ideal observers, searchers systematically under-adjusted to the target distribution, suggesting that training could improve multiple-target search in radiology and other crucial applications.

Abstract/Results: ABSTRACT:
Visual search is often guided by top-down attentional templates that specify target-defining features. But search can also occur at the level of multiple objects or categories. With adults, we measured the N2pc component, an event-related potential (ERP) marker of attentional target selection in two visual search experiments where targets were defined as either one item (e.g., the letter C), multiple items (e.g., the letters C, F, and X), or categorically (e.g., any letter). Experiment 1 encouraged category-based selection by consistently presenting targets among distractors from a different category (e.g., numbers). Reaction times (RTs) were fastest and the N2pc largest during search for a single item, demonstrating that target selection is most efficient when it is guided by a feature-specific template. There were no RT and N2pc differences between the category-based search task and search for two or three items in Experiment 1, indicating that category-defined templates were used in all three tasks. In Experiment 2, a category-based search strategy was not available because letter targets were now presented among letter distractors. Search efficiency decreased as the number of candidate target letters increased, suggesting that within-category search was based on multiple templates for each target. Results demonstrate that category-based search can operate at early visual stages, and that it is more efficient than within-category search for multiple targets, but less efficient than feature-guided search.

Abstract/Results: ABSTRACT:
Understanding category structure helps us make sense of the world, but little is known about how we use our knowledge about object categories during search. This study used event-related potential (ERP) markers of attentional object selection to investigate differences between search for one or two specific visual objects and category-based search, and to explore how categorical search can overcome working memory limitations. In contrast to most previous ERP studies of visual search which used colored shapes or alphanumeric stimuli, we employed more complex pictorial images of clothing and kitchen utensils. This enabled us to examine attentional selection in a more naturalistic context where participants may try to "find the pants" amongst kitchen utensils (or vice versa). In different blocks, they searched for one single target (e.g., pants), one target that could appear in two different views (e.g., a shirt in one of two possible orientations), two different targets (e.g., either a shoe or a scarf), or a category-defined target (e.g., any of eleven different clothing items). The N2pc component (an ERP marker of attentional object selection) was measured in response to target objects. As expected, this component was largest in the single-target condition where target selection could be based on a perceptual match with a search template. Presenting a single target object from different views had little effect on the N2pc, suggesting that search was object-based rather than view-based. N2pc components were attenuated and delayed in the two-target condition and even more so for category-defined targets, reflecting search efficiency costs when target selection cannot be guided by a single-object template. However, a reliable N2pc was present even during search for one of eleven possible category-defined targets demonstrating that category-based search remained surprisingly efficient. Our results show that category-based attentional guidance is readily available during search for complex naturalistic visual objects.

Activation of new attentional templates for real-world objects in visual search

Abstract/Results: ABSTRACT:
Visual search is controlled by representations of target objects (attentional templates). Such templates are often activated in response to verbal descriptions of search targets, but it is unclear whether search can be guided effectively by such verbal cues. We measured ERPs to track the activation of attentional templates for new target objects defined by word cues. On each trial run, a word cue was followed by three search displays that contained the cued target object among three distractors. Targets were detected more slowly in the first display of each trial run, and the N2pc component (an ERP marker of attentional target selection) was attenuated and delayed for the first relative to the two successive presentations of a particular target object, demonstrating limitations in the ability of word cues to activate effective attentional templates. N2pc components to target objects in the first display were strongly affected by differences in object imageability (i.e., the ability of word cues to activate a target-matching visual representation). These differences were no longer present for the second presentation of the same target objects, indicating that a single perceptual encounter is sufficient to activate a precise attentional template. Our results demonstrate the superiority of visual over verbal target specifications in the control of visual search, highlight the fact that verbal descriptions are more effective for some objects than others, and suggest that the attentional templates that guide search for particular real-world target objects are analog visual representations.

http://psycnet.apa.org/journals/xhp/40/4/1283/
Abstract/Results: ABSTRACT:
To compare the speed and efficiency of item-based and category-based attentional control during visual search for real-world objects, we measured N2pc components as electrophysiological markers of attentional target selection. In different blocks, participants searched for 1 or 2 specific target objects or for any object in a target category (items of clothing or kitchen objects). Search displays contained 6 line drawings of different objects, and targets always appeared together with 5 distractors from the other object category. The presence of N2pc components to categorically defined targets demonstrated that category-based search can operate at visuoperceptual processing stages. In contrast to previous findings for letter/digit search (Nako, Wu, & Eimer, 2014), target N2pc components were delayed by 40 ms during category-guided search relative to single-target search. This suggests that for objects and object categories that are less familiar than alphanumerical stimuli, category-guided target selection operates less efficiently than selection that is based on a physical match with an attentional template.

Category-based guidance of spatial attention during visual search for feature conjunctions
Publication year: 2016
URL:
https://content.apa.org/record/2016-25464-001
Abstract/Results: ABSTRACT:
The question whether alphanumerical category is involved in the control of attentional target selection during visual search remains a contentious issue. We tested whether category-based attentional mechanisms would guide the allocation of attention under conditions where targets were defined by a combination of alphanumerical category and a basic visual feature, and search displays could contain both targets and partially matching distractor objects. The N2pc component was used as an electrophysio-logical marker of attentional object selection in tasks where target objects were defined by a conjunction of color and category (Experiment 1) or shape and category (Experiment 2). Some search displays contained the target or a nontarget object that matched either the target color/shape or its category among 3 nonmatching distractors. In other displays, the target and a partially matching nontarget object appeared together. N2pc components were elicited not only by targets and by color-or shape-matching nontargets, but also by category-matching nontarget objects, even on trials where a target was present in the same display. On these trials, the summed N2pc components to the 2 types of partially matching nontargets were initially equal in size to the target N2pc, suggesting that attention was allocated simultaneously and independently to all objects with target-matching features during the early phase of attentional processing. Results demonstrate that alphanumerical category is a genuine guiding feature that can operate in parallel with color or shape information to control the deployment of attention during visual search.
