Human Foraging

Traditional search tasks have taught us much about vision and attention. Recently, several groups have begun to use multiple-target search to explore more complex and temporally extended “foraging” behaviour. Many of these new foraging tasks, however, maintain the simplified 2D displays and response demands associated with traditional, single-target visual search. In this respect, they may fail to capture important aspects of real-world search or foraging behaviour. In the current paper, we present a serious game for mobile platforms in which human participants play the role of an animal foraging for food in a simulated 3D environment. Game settings can be adjusted, so that, for example, custom target and distractor items can be uploaded, and task parameters, such as the number of target categories or target/distractor ratio are all easy to modify. We demonstrate how the app can be used to address specific research questions by conducting two human foraging experiments. Our results indicate that in this 3D environment, a standard feature/conjunction manipulation does not lead to a reduction in foraging runs, as it is known to do in simple, 2D foraging tasks. Differences in foraging behaviour are discussed in terms of environment structure, task demands and attentional constraints.

Human Foraging

In a previous series of papers, we have used an iPad task to explore how human participants “forage” through static displays containing multiple targets from two categories. A main finding was that when demands on attention were increased, foraging patterns tended to shift from random category selection to exhaustive category selection. In the current work, we created displays on a vertically oriented touch-screen containing identical target and distractor categories that could either be in motion or at rest. In separate blocks, participants selected target items using different modalities, specifically: a) mouse b) touchscreen or c) infrared hand tracker. Selected targets were always cancelled via a common button press response. Our interest was whether foraging patterns would be the same as those seen with our iPad task. Although the different selection modalities varied considerably in terms of rated familiarity and difficulty of use, they had only a minimal effect on patterns of foraging. There was a very consistent reduction in the number of category switches when attentional load was increased. However, the tendency to use exhaustive runs during high attention conditions was much reduced compared to the iPad task, particularly with dynamic displays. We suggest that this pattern is a consequence of generally slowed response times compared to the iPad task. These findings indicate that in addition to capacity limits, temporal constraints are likely to be an important determinant of foraging patterns in humans. We introduce the term foraging tempo to capture this latter notion and to emphasize the probable role played by the overall pace of the regular, repetitive selections required during multi-target search tasks.

AbstractCommonly used measures of human food insecurity differ categorically from measures determining food security in other species. In addition, human foraging behaviors may have arisen in a divergent evolutionary context from nonhuman foraging. Hence, a theoretical framework based on food insecurity and fat storage in nonhumans may not be appropriate for explaining associations between human food insecurity and obesity.

The Impact

Purpose Many children with developmental language disorder (DLD) have weaknesses in executive functioning (EF), specifically in tasks testing interference control and working memory. It is unknown how EF develops in children with DLD, if EF abilities are related to DLD severity and persistence, and if EF weaknesses expand to selective attention. This study aimed to address these gaps. Method Data from 78 children with DLD and 39 typically developing (TD) children were collected at three times with 1-year intervals. At Time 1, the children were 5 or 6 years old. Flanker, Dot Matrix, and Sky Search tasks tested interference control, visuospatial working memory, and selective attention, respectively. DLD severity was based on children's language ability. DLD persistence was based on stability of the DLD diagnosis. Results Performance on all tasks improved in both groups. TD children outperformed children with DLD on interference control. No differences were found for visuospatial working memory and selective attention. An interference control gap between the DLD and TD groups emerged between Time 1 and Time 2. Severity and persistence of DLD were related to interference control and working memory; the impact on working memory was stronger. Selective attention was unrelated to DLD severity and persistence. Conclusions Age and DLD severity and persistence determine whether or not children with DLD show EF weaknesses. Interference control is most clearly impaired in children with DLD who are 6 years and older. Visuospatial working memory is impaired in children with severe and persistent DLD. Selective attention is spared.
