“…However, the respective contributions of these dimensions to a given conceptualization are not always clear and this can be especially problematic if the considered dimensions lead to opposing conclusions. An example of this can be found in the recent human decision-making literature, where researchers have disagreed about the interpretation of exploration and exploitation behavior in a popular "sampling paradigm" of binary choice (Gonzalez & Dutt, 2011, 2012Hills & Hertwig, 2010, 2012. In this paradigm, participants can sample outcomes without consequences from two choice options for as long as they want, before making a final consequential choice between the two (Hertwig, Barron, Weber, & Erev, 2004).…”

Many decisions in the lives of animals and humans require a fine balance between the exploration of different options and the exploitation of their rewards. Do you buy the advertised car, or do you testdrive different models? Do you continue feeding from the current patch of flowers, or do you fly off to another one? Do you marry your current partner, or try your luck with someone else? The balance required in these situations is commonly referred to as the exploration-exploitation tradeoff. It features prominently in a wide range of research traditions, including learning, foraging, and decisionmaking literatures. Here, we integrate findings from these and other often-isolated literatures in order to gain a better understanding of the possible tradeoffs between exploration and exploitation, and we propose new theoretical insights that might guide future research. Specifically, we explore how potential tradeoffs depend on (1) the conceptualization of exploration and exploitation; (2) the influencing environmental, social, and individual factors; (3) the scale at which exploration and exploitation are considered; (4) the relationship and types of transitions between the two behaviors; and (5) the goals of the decision maker. We conclude that exploration and exploitation are best conceptualized as points on a continuum, and that the extent to which an agent's behavior can be interpreted as exploratory or exploitative depends upon the level of abstraction at which it is considered.

“…Interestingly, the development of visual expertise with training in radiology seems to indicate a move towards efficiency, and away from repeated attention to "non-priority" regions of the diagnostic image (G. Tourassi et al, 2013;Wolfe et al, 2015). Search for multiple visual targets, held in memory, is known as "hybrid search" (Wolfe, 2012a). Attention is not guided as effectively in this form of search, which may play a role in the training process of visual expertise in medicine (Eckstein, 2011).…”

“…In some circumstances, such as when searching for colour targets, overall speed decreases and accuracy falls when searching for two targets compared with single-target search, but both targets can be found with accuracy levels above chance. Indeed, much of the previous research on searching for multiple targets suggests that separate mental representations of all targets can be maintained successfully (Barrett & Zobay, 2014;Beck, Hollingworth, & Luck, 2012;Grubert & Eimer, 2015, 2016Irons, Folk, & Remington, 2012;Wolfe, 2012).…”

The efficiency of visual search for one (single-target) and either of two (dual-target) unfamiliar faces was explored to understand the manifestations of capacity and guidance limitations in face search. The visual similarity of distractor faces to target faces was manipulated using morphing (Experiments 1 and 2) and multidimensional scaling (Experiment 3). A dual-target cost was found in all experiments, evidenced by slower and less accurate search in dual- than single-target conditions. The dual-target cost was unequal across the targets, with performance being maintained on one target and reduced on the other, which we label “preferred” and “non-preferred” respectively. We calculated the capacity for each target face and show reduced capacity for representing the non-preferred target face. However, results show that the capacity for the non-preferred target can be increased when the dual-target condition is conducted after participants complete the single-target conditions. Analyses of eye movements revealed evidence for weak guidance of fixations in single-target search, and when searching for the preferred target in dual-target search. Overall, the experiments show dual-target search for faces is capacity- and guidance-limited, leading to superior search for 1 face over the other in dual-target search. However, learning faces individually may improve capacity with the second face.
