How do targets,nontargets, and scene context influence real-world object detection?

Humans excel at finding objects in complex natural scenes, but the features that guide this behaviour have proved elusive. We used computational modeling to measure the contributions of target, nontarget, and coarse scene features towards object detection in humans. In separate experiments, participants detected cars or people in a large set of natural scenes. For each scene, we extracted target-associated features, annotated the presence of nontarget objects (e.g., parking meter, traffic light), and extracted coarse scene structure from the blurred image. These scene-specific values were then used to model human reaction times for each novel scene. As expected, target features were the strongest predictor of detection times in both tasks. Interestingly, target detection time was additionally facilitated by coarse scene features but not by nontarget objects. In contrast, nontarget objects predicted target-absent responses in both person and car tasks, with contributions from target features in the person task. In most cases, features that speeded up detection tended to slow down rejection. Taken together, these findings demonstrate that humans show systematic variations in object detection that can be understood using computational modeling.     

Task demands, task interest, and task performance: implications for human subjects research and practicing what we preach

Through the continuous investigation of humans in organizations, we have learned much about motivation, attitudes, and performance. For example, Yukl and others have helped increase our understanding of influence tactics and the effect they have on the performance of subordinates, supervisors, and peers. Some tactics (and combinations of tactics) lead to resistance, some lead to compliance, and some lead to commitment. In this study, we raise the question of whether or not we incorporate our knowledge of these research findings into the design, implementation, and interpretation of our own research studies that require the participation of human subjects. In a survey of 134 subjects from a previous social science study, we found that performance varied across the sample, consistent with the concepts of resistance, compliance, and commitment. In addition, the variance in performance could be explained, in part, by task interest and perceived task demands. Implications are discussed.     

Indian secularism,dialogue and the Ayodhya dispute

Indian secularists compound difficulties for the emergence of a genuinely secular society by relying on an exclusively constitutional rather than a dialogical approach to settle India’s religious disputes as manifested in Ayodhya and elsewhere. There are, however, intellectuals who favour dialogue with religious communities to strengthen secularism but are afraid of suggesting dialogue with contending parties on contentious issues like the Ayodhya dispute for fear of legitimising religious fundamentalism. As a result, the notion of ‘contentious dialogue’ is avoided even while the need for dialogue is recognised. Instead of religious grievances getting resolved through law, they get embroiled over a period of time and result in the rise of religious fundamentalism and terrorism, thereby deepening the crisis of secularism. In the Ayodhya dispute, communities encouraged by the secular state have followed a legal approach to the settlement of their religious grievances since 1950. While the dispute languished in court, the demolition of the Babri Mosque in 1992, the emergence of religious terrorism and the riots in Gujarat in 2002 followed. All these developments are in some way interrelated and need a broad and holistic counter-strategy. Only a dialogic approach will induce communities to comprehend the interconnected nature of problems arising from the Ayodhya dispute and make them seek solutions outside the law. This paper proposes a model of reconciliation based on the themes of recognition of intrinsic faith, negotiation with extrinsic elements of each religion and sacrifice. This dialogical approach ought to be carried out by a non-sectarian political society that must involve ruling and opposition parties, NGOs, lawyers, administrators and contending religious organisations in order to seek a realistic solution to the Ayodhya dispute in the larger and long-term interest of a secular polity in India.     

The Effect of the Number of Opinion Seekers and Leaders on Technology Attitudes and Choices

Status, which implies a positive evaluation by other members of the group, remains one aspect of group structure that has not received much theoretical or empirical evaluation. Although a number of researchers have focused on status and its emergence, the influence of the number of group members who share status has never been explored. This paper focuses on group relationships and examines the impact of the number of opinion seekers and opinion leaders on individual technology‐related attitudes and behavior. The research model was built on the social influence model presented by J. Fulk (1993) and tested across multiple moderating variables suggested in the social psychological literature including cohesiveness, three types of uncertainty, two levels of uncertainty, and two media types. Contrary to the dominant theoretical position, the number of opinion leaders did not always influence technology attitudes; rather, in host of high‐attraction conditions, the number of opinion seekers had a significant influence. The influence of the number of opinion seekers was moderated by the degree of cohesiveness—indicating internalization of attitudes rather than compliance. Also moderating this relationship were the type and level of uncertainty and the type of media chosen.
