Modeling drivers' visual attention allocation while interacting with in-vehicle technologies

In 2 experiments, the authors examined how characteristics of a simulated traffic environment and in-vehicle tasks impact driver performance and visual scanning and the extent to which a computational model of visual attention (SEEV model) could predict scanning behavior. In Experiment 1, the authors manipulated task-relevant information bandwidth and task priority. In Experiment 2, the authors examined task bandwidth and complexity, while introducing infrequent traffic hazards. Overall, task priority had a significant impact on scanning; however, the impact of increasing bandwidth was varied, depending on whether the relevant task was supported by focal (e.g., in-vehicle tasks; increased scanning) or ambient vision (e.g., lane keeping; no increase in scanning). The computational model accounted for approximately 95% of the variance in scanning across both experiments.     

Searching for self and relationships online.

The purpose of this project was to study how Internet use relates to psychological well-being, relationships, the self and identity. University students (N = 203) completed a battery of questionnaires including measures of time spent online, "pathological" Internet use, Internet motivation, loneliness, relationship quality, self-concept clarity, and ego identity. Results showed positive relationships between measures of Internet use and loneliness. As well, face-to-face relationships were rated higher on both positive and negative quality dimensions relative to online relationships. Finally, Internet use was negatively correlated with self-concept clarity, and associated with moratorium identity status. These results suggest that the Internet may be an important aid for young adults as they searched for an adult identity.     

Reach and posture hand preferences during arboreal feeding in Sifakas (Propithecus sp.): a test of the postural origins theory of behavioral lateralization

Sixteen sifakas (11 Propithecus verreauxi coquereli, 2 Propithecus verreauxi verreauxi form majori, and 3 Propithecus tattersalli) were videotaped as they fed on leaves in an arboreal context. The hand used to feed and the hand used to maintain postural stability was coded. For each subject, the lateral bias of the hand used to feed was opposite the hand used in postural support. Seven sifakas displayed no bias for feeding or posture-related hand use, 7 sifakas displayed significant feeding-related reach preferences for pulling branches to the mouth (5 left- and 2 right-hand preferences), and 9 sifakas exhibited significant hand preferences for postural support (2 left-, 7 right-hand preferent). Although these data do not strongly support the postural origins theory of behavioral lateralization, the modal preference pattern for sifakas that displayed significant hand preferences for posture and feeding involve a left bias for feeding and a right bias for postural support. s reserved).     

Social facilitation in young toddlers

As a test of Zajonc's social facilitation hypothesis, the behavior of 18 young toddlers (16-24 mo.) was observed. Their performance on a simple task was incongruent with his hypothesis, that is, these young toddlers may not evaluate their outcomes in relation to a social standard.     

Roles of salience and strategy in conjunction search

In some cases, the search for a conjunction target proceeds through the smaller group of elements in a display, whereas in others, search is limited to those elements that share a particular feature with the target. In 6 experiments, participants searched for a conjunction target among displays consisting of various proportions of 2 distractor types. Smaller-group search was more prevalent than target-feature search with denser displays and with features that were highly discriminable. Explicit instructions to limit search to a specific feature affected performance only when the discriminability of the guiding feature was much greater than the other target feature. Together, these experiments show that bottom-up factors have more influence in guiding conjunction searches than previously thought.     

‘As in a Mirror’: Jonathan Edwards,Self-Love and Enlarging to Receive Another

Through a robust deployment of visual metaphors, Jonathan Edwards’s theology utilizes notions of vision to articulate his doctrine of God, creation, anthropology, redemption and ultimately glorification. Focusing on anthropology, this article attends to how human beings are constituted through sight, and reconstituted (i.e. regenerated) as they are contemplated in the Son and as they are given a vision of the Father in the Son by the Spirit of illumination. Put differently, Edwards’s anthropology is ordered around its teleology of becoming like God only if one can ‘see him as he is’ (1 Jn 3:2), which is anticipated by faith in this present age and ‘through a mirror dimly’ (1 Jn 13:12). After mooring his anthropology to broader theological concerns, the article narrows to consider how Edwards’s idiosyncratic personalism is developed around the notion of a ‘reflective self’ that can enlarge to internalize an ‘other’. Clarifying this notion is a brief comparison of a similar construction in Thomas Aquinas, showing how Edwards’s theory of loving neighbor as oneself is a unique contribution to questions concerning personhood, self-love and neighbor-love.     

The Southern Pub Crawl and Brawl: An Examination of the Alcohol–Violence Nexus in a Southern City

This research examines the relationship between alcohol availability and crime, specifically the variation of effects between the presence of off- and on-site establishments on violent crime. We contribute to extant research by providing a more comprehensive disaggregation of alcohol establishments. Framed in routine activities theory, we argue that alcohol availability will exacerbate violent crime rates by increasing quantities of motivated offenders and suitable targets, while simultaneously decreasing the number of capable guardians. We find a nuanced relationship between the presence of alcohol establishments and violence that varies based on establishment type as well as the characteristics of its block group.     

Trends in Behavior-Analytic Gambling Research and Treatment

The purpose of the present review was to analyze research outcomes for all gambling studies reported in the behavior analysis literature. We used the search term “gambling” to identify articles that were published in behaviorally oriented journals between the years 1992 and 2012 and categorized the content of each article as empirical or conceptual. Next, we examined and categorized the empirical articles by inclusion of an experimental manipulation and treatment to alleviate at least some aspect of pathological gambling, participant population used, type of gambling task employed in the research, whether the participants in the study actually gambled, and the behavioral phenomena of interest. The results show that the rate of publication of gambling research has increased in the last 6 years, and a vast majority of articles are empirical. Of the empirical articles, examinations of treatment techniques or methods are scarce; slot machine play is the most represented form of gambling, and slightly greater than half of the research included compensation based on gambling outcomes within experiments. We discuss implications and future directions based on these observations of the published literature.     

Using a Compromise Programming Framework to Integrating Spatially Specific Preference Information for Forest Management Problems

The development of forest management plans is a multi‐criteria problem that usually involves multiple stakeholders. In forested recreational areas or natural parks, stakeholders could include government officials, forest companies and visitors to the area. With the progress of mobile phone technology, preference information (including aesthetic values) can be conveniently obtained from stakeholders while they are in the forest. This paper develops a methodological approach that incorporates place‐specific opinion preference into the development of alternative forest management plans. Through the use of a modified Compromise Programming approach, prospective alternatives are developed, which optimize the opinions of stakeholders and the quantity of timber over time depending on specified parameters. The analysis is based on a small simulated forest holding and place‐specific simulated opinion data. To allow for a comparison between potential stakeholder groups, the opinion data was generated by a method that produced three separate groups. The results indicate the practical use of place‐specific preferences and provide a means to incorporate the information to generate possible alternative plans. In addition, the analysis highlights that by segregating the preference information into groups, the planning of more specific courses of actions can be made. Copyright © 2015 John Wiley & Sons, Ltd.
