Aging and Top-Down Attentional Control in Visual Search

  title={Aging and Top-Down Attentional Control in Visual Search},
  author={David J. Madden and Stephen R. Mitroff},
Many visual tasks, such as airport baggage screening, rely heavily on the ability to accurately and efficiently search for and detect target items amongst distractors. For example, in a luggage X-ray, a weapon such as a knife must be discriminated from visually similar items (McCarley, Kramer, Wickens, Vidoni, & Boot, 2004). It is critical to the mission of the Human Factors/Behavior Sciences Division of the Department of Homeland Security (DHS) to be able to assess and maintain this skill set… 
False Memories in Healthy Older Adults
The aim of this paper is to discussed the literature about affect of aging on false memories  and explain the retrieval model as an underlying factor. Therefore, it is a mini review which focused on
Implementation and evaluation of the EasyVote tallying component and ballot
An EasyVote tallying component is developed and a user study is conducted to determine whether electoral officials would detect discrepancies and two alternatives are proposed, one of which is significantly better than the original EasyVote ballot with respect to ease of verification and understandability.
Usable Security Evaluation of EasyVote in the Context of Complex Elections
Elections differ not only between, but also within, countries. Some elections have very simple voting rules and ballots. For instance, in the parliamentary elections in Estonia or Germany, voters can

Investigating whether aging results in an increased attentional blink effect in older adults as compared to young adults showed that in young adults, successful identification of the first target interfered with identifying the second target, as well as the initiation time (action planning) of pointing to the second targets.
Aging and filtering by movement in visual search.
Age-equivalence in the processes which underlie feature search in dynamic environments as well as those processes responsible for the segregation of moving and stationary objects in the visual field are suggested.
Searching from the Top Down: Ageing and Attentional Guidance during Singleton Detection
Top-down attentional control mechanisms interact with bottom-up processes to guide search for targets, and that in the context of singleton detection these mechanisms of top-down control are preserved for older adults are indicated.
Adult age differences in visual search accuracy: attentional guidance and target detectability.
In the most difficult condition (conjunction search), the likelihood of missing a target was greater for older adults than for younger adults, and this effect was not attributable entirely to generalized slowing.
Overriding stimulus-driven attentional capture
It is concluded that goal-directed selection of a specific known featural identity may override stimulus-driven capture by salient featural singletons and top-down selectivity is indeed possible during visual search.
Visual search and selective attention
Visual search is a key paradigm in attention research that has proved to be a test bed for competing theories of selective attention. The starting point for most current theories of visual search has
Bottom-up and Top-down Control in Visual Search
The major result was that relative target–distractor salience and target-distractor similarity affected search performance independently, and performance was better in cases where the irrelevant distractor was not a salient item in the search display and did not look similar to the target.
Age differences in same-different judgments as a function of multidimensional similarity.
Results suggest that age differences in free search are due, in part, to an age-related decline in the speed of evaluating object congruence.
Visual selective attention: a theoretical analysis.
A framework which allows a consistent interpretation of data regarding visual selection in visual search tasks is outlined, concluding that visual selection is to a large extent determined by the physical characteristics of the stimuli present in the visual field.
Age-related preservation of top-down attentional guidance during visual search.
It is concluded that under conditions that equate the physical structure of individual displays, top-down attentional guidance can be at least as effective for older adults as for younger adults.
