Inhibition of return functions within but not across searches

Inhibition of return (IOR) facilitates visual search by discouraging the reinspection of recently processed items. We investigated whether IOR operates across two consecutive searches of the same display for different targets. In Experiment 1, we demonstrated that IOR is present within each of the two searches. In Experiment 2, we found no evidence for IOR across searches. In Experiment 3, we showed that IOR is present across the two searches when the first search is interrupted, suggesting that the completion of the search is what causes the resetting of IOR. We concluded that IOR is a partially flexible process that can be reset when the task completes, but not necessarily when it changes. When resetting occurs, this flexibility ensures that the inhibition of previously visited locations does not interfere with the new search.     

When is the gift given? Organ donation,social representations,and an opportunity to register

The gift of life doctrine underpins Australia's approach to organ donation: in legislation, clinical practice, community awareness campaigns, and educational activities. In this paper, we present an approach that situates an understanding of organ donation within a social representation framework as a system of values, ideas, and practices. In cadaveric donation, the final giving‐of‐the‐gift can never be by the donor, leading us to ask where the potential donor's decision to give the gift really lies. We present research from three studies that explored the relationship between what was socially understood about organ donation and the registration of donation intent. Drawing from three socially and culturally diverse populations, we asked people working in a corporate city institution and those attending two football matches in the outer city area to complete a word‐association task and Likert‐scale belief questions about organ donation—followed by an opportunity to register immediately on the Australian Organ Donor Register. Driven by the interdependent themata of life/death and self/other, the gift of life doctrine is inextricably linked with the loss of life emerging as both positive and negative beliefs allowing their relationship to actual registration behaviour to be observed. Our findings suggest that in many instances, the potential donor's genuine desire to give the gift lies in the tension between positive and negative beliefs, manifesting as a consent registration when the positive beliefs about donation prevail and an immediate opportunity to register is available.     

The time course of abstract visual representation

Studies in change blindness re-enforce the suggestion that veridical, pictorial representations that survive multiple relocations of gaze are unlikely to be generated in the visual system. However, more abstract information may well be extracted and represented by the visual system. In this paper we study the types of information that are retained and the time courses over which these representations are constructed when participants view complex natural scenes. We find that such information is retained and that the resultant abstract representations encode a range of information. Different types of information are extracted and represented over different time courses. After several seconds of viewing natural scenes, our visual system is able to construct a complex information-rich representation.     

Nietzsche on guilt: Dependency,debt, and imperfection

In this paper, I offer a new way of reading Nietzsche's second essay in On the Genealogy of Morality. At the heart of my account is the claim that Nietzsche is primarily interested in a persistent or existential form of guilt in this essay and only concerned with locally reactive cases of guilt as a function of this deeper phenomenon. I argue that, for Nietzsche, this persistent form of guilt develops out of a deep feeling of indebtedness or owing that accompanies a fearful sense of dependency on the gods. When this sense of dependent indebtedness mixes with bad conscience, which arises through the shift from prehistoric tribes to state‐like communities, it becomes a moral problem; vast numbers of “slaves and serfs” (GM II.20) start to feel like they are not sufficiently honoring their dependent relationship with the gods. It is this feeling of persistent guilt that Nietzsche thinks metastasizes into Christian guilt.     

A social cure in the community: A mixed-method exploration of the role of social identity in the experiences and well-being of community volunteers

Cohesive, resilient communities are vital to the well-being of residents. Uncovering the determinants of successful community identities is therefore essential to progressing the community health agenda. Engaging in community participation through volunteering may be one pathway to building local community identity and enhancing residents’ health and well-being, but the group processes connecting them remain unexplored. We conducted two studies investigating these dynamics using the “Social Cure” perspective. First, we analysed 53 in-depth interviews with volunteers, finding that community relationships shaped their experiences and that volunteering influenced their sense of community belonging, support, and well-being. Second, a community survey (N = 619) revealed that volunteering predicts well-being through the serial mediators of community identification and social support. Our article demonstrates the Social Cure processes involved in community-based volunteering, their impact on community identity, support and well-being, and their implications for community health, and the provision and sustainability of community voluntary action and interventions.     

Academic performance,prejudice, and the jigsaw classroom: new pieces to the puzzle

This field study investigated the effects of a cooperative learning environment and a Jigsaw classroom environment on academic performance, self-esteem, liking of school, liking of peers, and racial prejudice. The subjects were 103 children in Grades 4–6, in two separate schools. The cooperative learning condition was used as a baseline measure of the effects of cooperation, against which the effects of a Jigsaw method, involving both cooperation and interdependence, were compared. The results reveal that Jigsaw produced significant improvements on measures of academic performance, liking of peers, and racial prejudice. In contrast, the effect of the cooperative condition was to exacerbate pre-existing intergroup tensions. The present findings demonstrate that the Jigsaw method can be applied successfully in Australian conditions, and lend support to Allport's contact hypothesis. © 1998 John Wiley & Sons, Ltd.     

ScanMatch: A novel method for comparing fixation sequences

We present a novel approach to comparing saccadic eye movement sequences based on the Needleman-Wunsch algorithm used in bioinformatics to compare DNA sequences. In the proposed method, the saccade sequence is spatially and temporally binned and then recoded to create a sequence of letters that retains fixation location, time, and order information. The comparison of two letter sequences is made by maximizing the similarity score computed from a substitution matrix that provides the score for all letter pair substitutions and a penalty gap. The substitution matrix provides a meaningful link between each location coded by the individual letters. This link could be distance but could also encode any useful dimension, including perceptual or semantic space. We show, by using synthetic and behavioral data, the benefits of this method over existing methods. The ScanMatch toolbox for MATLAB is freely available online (www.scanmatch.co.uk).
