Viewpoint and orientation influence picture recognition in the blind

In the first three experiments, subjects felt solid geometrical forms and matched raised-line pictures to the objects. Performance was best in experiment 1 for top views, with shorter response latencies than for side views, front views, or 3-D views with foreshortening. In a second experiment with blind participants, matching accuracy was not significantly affected by prior visual experience, but speed advantages were found for top views, with 3-D views also yielding better matching accuracy than side views. There were no performance advantages for pictures of objects with a constant cross section in the vertical axis. The early-blind participants had lower performance for side and frontal views. The objects were rotated to oblique orientations in experiment 3. Early-blind subjects performed worse than the other subjects given object rotation. Visual experience with pictures of objects at many angles could facilitate identification at oblique orientations. In experiment 5 with blindfolded sighted subjects, tangible pictures were used as targets and as choices. The results yielded superior overall performance for 3-D views (mean, M = 74% correct) and much lower matching accuracy for top views as targets (M = 58% correct). Performance was highest when the target and matching viewpoint were identical, but 3-D views (M = 96% correct) were still far better than top views. The accuracy advantage of the top views also disappeared when more complex objects were tested in experiment 6. Alternative theoretical implications of the results are discussed.     

Health Care Chaplains and their Role on Institutional Ethics Committees: An Australia Study

This paper presents the results of the largest Australian pastoral study concerning the perceptions of health care chaplains about their involvement on hospital research ethics committees (also known in some contexts as institutional ethics committees). Survey results from over 300 Australian health care chaplains indicated that nearly 90% of chaplains believed there was merit in chaplains serving on hospital research ethics committees, yet only a minority (22.7%) had ever participated on such committees. Data from in-depth interviews is also presented exploring the reasons for the lack of participation and the varying opinions regarding the role, appropriateness, and value of chaplains on ethics committees. Some implications of this study with respect to chaplaincy, hospital research ethics committees, health care institutions, ecclesiastical institutions, and government responsibilities are discussed.     

Adults' memories of childhood: Affect,knowing, and remembering

Adult questionnaire respondents reported, for each of a number of events, if they had experienced that event during childhood and, if so, if they remembered the experience or merely knew it had happened. Respondents also rated the emotion of each event and judged whether they would remember more about each reportedly experienced event if they spent more time trying to do so. Study 1 respondents were 96 undergraduates, whereas Study 2 tested 93 community members ranging widely in age. Respondents often reported no recollections of reportedly experienced events. Reportedly experienced events rated as emotional were more often recollected than those rated as neutral, and those rated as positive were more often recollected than those rated as negative. Predicted ability to remember more was related to current memory. Claims of remembering reportedly experienced events increased with age, but predicted ability to remember more about them declined with age.     

Serial position curves in short‐term memory: Functional equivalence across modalities

Four experiments investigated item and order memory for sequences of seen unfamiliar faces and heard nonwords. Experiments 1 and 3 found bowed serial position curves using the serial reconstruction test of order with faces and nonwords, respectively. Experiments 2 and 4 found limited recency, no primacy, and above chance performance on all items using a two‐alternative forced choice (2AFC) test of item recognition, again with faces and nonwords. These results suggest that the different serial position curves typically found using traditional paradigms for exploring visual and verbal short‐term memory are due to differences in the methods used rather than modality‐specific mechanisms.     

Alcohol intoxication and memory for events: A snapshot of alcohol myopia in a real-world drinking scenario

Alcohol typically has a detrimental impact on memory across a variety of encoding and retrieval conditions (e.g., Mintzer, 2007; Ray & Bates, 2006). No research has addressed alcohol's effect on memory for lengthy and interactive events and little has tested alcohol's effect on free recall. In this study 94 participants were randomly assigned to alcohol, placebo, or control groups and consumed drinks in a bar-lab setting while interacting with a “bartender”. Immediately afterwards all participants freely recalled the bar interaction. Consistent with alcohol myopia theory, intoxicated participants only differed from placebo and control groups when recalling peripheral information. Expanding on the original hypervigilance hypothesis, placebo participants showed more conservative reporting behaviour than the alcohol or control groups by providing more uncertain and “don't know” responses. Thus, alcohol intoxication had confined effects on memory for events, supporting and extending current theories.     

A Qualitative Exploration of Athletes' Past Experiences With Doping Prevention Education

The purpose of this study was to explore athletes' experiences with doping education and their recommendations to improve current education to create more effective doping prevention interventions. Following a constructivist approach, interviews were conducted with 21 athletes and analyzed inductively with thematic analysis. Six themes were identified relating to athletes' experiences with doping education and recommendations for improving it. Athletes commonly described receiving insufficient doping education during adolescence, highlighting the need for increased doping prevention efforts. Recommendations for future educational programs include addressing doping prevention collaboratively, implementing education at younger ages, and assuring the programs are engaging and interactive.     

Predicting land use voting behavior: expanding our understanding of the influence of attitudes and social norms

Voting to tax oneself in the current economic climate seems improbable. Framed in theories of normative influence and behavior change, this study tests the factors that predict voting for a county‐level millage (i.e., tax) to fund land preservation. Behavioral beliefs that contribute to people's attitudes toward the millage are identified and a model is tested with an expanded normative component. Results indicate that attitudes and subjective norms significantly predict voting intentions, and injunctive norms (i.e., people's perceptions of others' approval of taking an action) add significantly to the model's predictive power. Findings are reinforced by election results in which the millage proposal passed and can contribute to the applied literature by identifying social‐psychological factors that can be targeted with campaign messages.     

The Question of Higher Education for the Blind

Building on the theory of reasoned action (I. Ajzen & M. Fishbein, 1973, 1980; M. Fishbein & I. Ajzen, 1975) and expectancy theory, the authors examined the mediating role of alcohol expectancies in adolescent drinking behaviors by testing whether alcohol expectancy outcomes and valuations (the extent to which these outcomes are perceived as good or bad) mediate the association between peer influences and lifetime alcohol use. Early adolescents (N = 904) from 2 public middle schools in western Michigan completed a battery of questionnaires. Overall, results showed that alcohol expectancies and valuations partially mediated the relations between peer influences (peer use and peer approval) and lifetime alcohol use. The findings suggest that associating with peers who are perceived as using alcohol and approving of drinking may influence adolescents’ alcohol expectancies. The authors briefly discuss future research directions and implications for prevention.
