And Behavior

Transportation Security Officers (TSOs) and Behavior Detection Officers (BDOs) are an integral part of the Transportation Security Administration’s (TSA) multilayered security program. Both officers are required to visually search their environments for prohibited items and cues that might be indicative of a threat. The purpose of this project was to identify factors that predicted the visual search success of these officers. A simulated visual search task was completed by 375 TSOs and BDOs, along with a battery of surveys designed to measure individual differences in personality traits, abilities, hobbies, and spatial ability. Results showed that TSOs and BDOs were highly accurate in their searches but that TSOs searched images faster than BDOs without sacrificing accuracy. Additional results showed that the strongest predictors of visual search accuracy were search speed and search consistency, but spatial ability emerged as a significant predictor for TSOs and frequency of video-game play emerged as a significant predictor for BDOs. Additional traits were also correlated with search performance but did not emerge as significant predictors in our regression models. Practical implication and directions for future research are discussed.

This study investigated visual search performance for target aircraft symbols on a Cockpit Display of Traffic Information (CDTI). Of primary interest was the influence of target brightness (intensity) and highlighting validity (search directions) on the ability to detect a target aircraft among distractor aircraft. Target aircraft were distinguished by an airspace course that conflicted with Ownship (that is, the participant's aircraft). The display could present all (homogenous) bright aircraft, all (homogenous) dim aircraft, or mixed bright and dim aircraft, with the target aircraft being either bright or dim. In the mixed intensity condition, participants may or may not have been instructed whether the target aircraft was bright or dim. Results indicated that highlighting validity facilitated better detection times. However, instead of bright targets being detected faster, dim targets were found to be detected more slowly in the mixed intensity display than in the homogenous display. This relative slowness may be due to a delay in confirming the dim aircraft to be a target when it was among brighter distractor aircraft. This hypothesis will be tested in future research.

Field Of Vision

Visual search is a popular tool for studying a range of questions about perception and attention, thanks to the ease with which the basic paradigm can be controlled and manipulated. While often thought of as a sub-field of vision science, search tasks are significantly more complex than most other perceptual tasks, with strategy and decision playing an essential, but neglected, role. In this review, we briefly describe some of the important theoretical advances about perception and attention that have been gained from studying visual search within the signal detection and guided search frameworks. Under most circumstances, search also involves executing a series of eye movements. We argue that understanding the contribution of biases, routines and strategies to visual search performance over multiple fixations will lead to new insights about these decision-related processes and how they interact with perception and attention. We also highlight the neglected potential for variability, both within and between searchers, to contribute to our understanding of visual search. The exciting challenge will be to account for variations in search performance caused by these numerous factors and their interactions. We conclude the review with some recommendations for ways future research can tackle these challenges to move the field forward.

Color Texture

Previously, it had been found that texture-coding was ineffective at reducing search time (Perlman & Swan, 1993). In the experiment reported here, 16 subjects searched for blank-, color-, texture-, and density-coded targets of varying complexity in a naturalistic task. The data showed that all non-blank methods were significantly and about equally more effective at reducing search time than blank-coding (no coding). The difference of outcome with previous results is explained by task simplification and by the control of possibly confounding factors. The difference suggests that coding techniques using texture, and possibly other methods, should be evaluated in context. The similar performance of color-, texture-, and density-coding is explained by the use of equal-saturation and equal-brightness colors. Recommendations for the design of effective coding methods and for future research are discussed.

Manual Interaction

Computer use generally requires manual interaction with human-computer interfaces. In this experiment, we studied the influence of manual response preparation on co-occurring shifts of attention to information on a computer screen. The participants were to carry out a visual search task on a computer screen while simultaneously preparing to reach for either a proximal or distal switch on a horizontal device, with either their right or left hand. The response properties were not predictive of the target’s spatial position. The results mainly showed that the preparation of a manual response influenced visual search: (1) The visual target whose location was congruent with the goal of the prepared response was found faster; (2) the visual target whose location was congruent with the laterality of the response hand was found faster; (3) these effects have a cumulative influence on visual search performance; (4) the magnitude of the influence of the response goal on visual search is marginally negatively correlated with the rapidity of response execution. These results are discussed in the general framework of structural coupling between perception and motor planning.

This concluding chapter summarizes the main findings of the preceding chapters in light of the model of contextual effects on voter behavior. Accordingly, the processes of communication and politicization are of key importance for contextual effects. By implication, we cannot take for granted that contextual features exert sizable effects on voters’ opinion formation and behavior in each and every case. Findings about contextual effects are also context-sensitive and thus do not lend themselves to generalization by default. These observations suggest that context plays a nuanced and conditional role in voting behavior. Exploring it further should be a focal topic of future research on political behavior and democratic politics.

Morality and gender are intersecting realms of human thought and behavior. Reasoning and action at their intersection (e.g., views of women’s rights legislation) carry important consequences for societies, communities, and individual lives. In this chapter, the authors argue that children’s developing views of morality and gender reciprocally shape one another in important and underexplored ways. The chapter begins with a brief history of psychological theory and research at the intersection of morality and gender and suggests reasons for the historical failure to view gender attitudes through moral lenses. The authors then describe reasons for expecting morality to play an important role in shaping children’s developing gender attitudes and, reciprocally, for gender attitudes to play an important role in shaping children’s developing moral values. The authors next illustrate the importance and relevance of these ideas by discussing two topics at the center of contentious debate in the United States concerning ethical policy and practice: treatment of gender nonconformity and gender-segregated schooling. The chapter concludes with suggestions for future research.
