Brightness Change

The visual system relies on several heuristics to direct attention to important locations and objects. One of these mechanisms directs attention to sudden changes in the environment. Although a substantial body of research suggests that this capture of attention occurs only for the abrupt appearance of a new perceptual object, more recent evidence shows that some luminance-based transients (e.g., motion and looming) and some types of brightness change also capture attention. These findings show that new objects are not necessary for attention capture. The present study tested whether they are even sufficient. That is, does a new object attract attention because the visual system is sensitive to new objects or because it is sensitive to the transients that new objects create? In two experiments using a visual search task, new objects did not capture attention unless they created a strong local luminance transient.

Task Irrelevant

Visual features previously associated with reward can automatically capture attention even when task-irrelevant, a phenomenon known as value-driven attention capture (VDAC, Anderson et al., 2011b). VDAC persists without reinforcement, unlike other forms of learning where removing reinforcement typically leads to extinction (Pavlov, 1927). This study examined the conditions under which VDAC could be extinguished. In four experiments, factors known to affect attention were manipulated to examine their impact on VDAC and its extinction. All experiments included learning and test phases. During learning, participants completed a visual search task during which one of two target colors was associated with a reward, and the other with no reward. During test, one week later, participants completed another visual search task during which the reward association was not reinforced. The task during test had twice as many exposures to the rewarded feature than during learning to ensure a sufficient number of exposures to observe extinction. When a rewarded feature remained task-relevant (Exp. 1), the capture effect was reduced, but extinction was not complete. When a rewarded feature was made task-irrelevant (Exp. 2) there was no evidence of extinction. When the frequency of exposure to the task-irrelevant rewarded feature was reduced (Exp. 4), VDAC also persisted. A physically salient target (Exp. 3) resulted in the fastest rate of VDAC extinction. These findings demonstrate that the extinction of VDAC depends on various factors that affect priority for attention, especially those that bias attention away from reward-associated features.

Adaptive Choice

There are many strategies we can use to control attention when approaching a visual search task, but some are more effective than others. How do we choose the most optimal strategy? We have proposed that individuals must appraise the stimulus environment, taking in relevant statistical information about task-relevant features. In the present experiment, we examined whether interfering with the appraisal process via a secondary task decreases participants’ use of the optimal strategy. We used a modified version of the Adaptive Choice Visual Search paradigm (Irons & Leber, 2016; 2018), whereby individuals can freely search for either of two targets on every trial. Each search display was preceded by a colored environmental preview, offering participants time to appraise the display and determine which target would be more optimal to search for. On some blocks, participants also completed a secondary task – a central line-length judgment – either before or during this colored preview. We found that participants were significantly less likely to search optimally when the line task occurred during the colored preview than when it occurred beforehand or was absent. Insofar as the secondary task disrupts an individual’s ability to engage in appraisal, these results support the need for such an appraisal mechanism in the optimal choice of attentional control settings.

Search Performance

Ten subjects performed a task on a head-coupled simulator using various sized fields-of-view (FOVs). The task required them to visually acquire, remember the location of, monitor and shoot 3 or 6 objects. In addition they were required to perform a secondary tracking task. Performance at monitoring and shooting the objects decreased with decreasing FOV size and increasing number of objects. Secondary task performance also decreased with decreasing FOV. The ability to recall the location of objects was unaffected by changes in FOV size. However, tracking performance was degraded while subjects used smaller FOVS to find and learn the location of objects. The results indicate that although visual search performance can be maintained with small FOVs, it is done in a manner which may compromise performance at other tasks.
