The fans’ beliefs

O’Brien maintains that the behavior of football fans should be analyzed not merely in terms of individual behavior but also in terms of group dynamics. He found in the Milltown Supporters Club several such groups.     

Naming Faces: The Effects of Facial Distinctiveness and Surname Frequency

The effects of the frequency of a surname in the population and of the distinctiveness of a face on the latency to name famous faces were explored. Distinctive faces were named more quickly than were typical faces. Celebrities with low-frequency surnames were named faster than celebrities with high-frequency surnames, but only if their faces were distinctive. Subsequent experiments showed that the effect of surname frequency could not be attributed to differences in the articulatory onsets of the surnames and was not present in a task that did not require a naming response. Experiments in which surnames were taught to previously unfamiliar faces showed that familiar surnames (e.g. the surnames of celebrities) were produced more rapidly than were unfamiliar surnames. If familiar surnames were taught, no effect of surname frequency was observed. It is concluded that lexical access to peoples' names is frequency sensitive—surnames shared by few individuals are accessed faster than are high-frequency surnames. However, when learning names to unfamiliar faces, familiar surnames (i.e. the surnames of people already known to the subject) are learned and accessed more quickly than unfamiliar surnames.     

The Dynamics of Visual Reweighting in Healthy and Fall-Prone Older Adults

Multisensory reweighting (MSR) is an adaptive process that prioritizes the visual, vestibular, and somatosensory inputs to provide the most reliable information for postural stability when environmental conditions change. This process is thought to degrade with increasing age and to be particularly deficient in fall-prone versus healthy older adults. In the present study, the authors investigate the dynamics of sensory reweighting, which is not well-understood at any age. Postural sway of young, healthy, and fall-prone older adults was measured in response to large changes in the visual motion stimulus amplitude within a trial. Absolute levels of gain, and the rate of adaptive gain change were examined when visual stimulus amplitude changed from high to low and from low to high. Compared with young adults, gains in both older adult groups were higher when the stimulus amplitude was high. Gains in the fall-prone elderly were higher than both other groups when the stimulus amplitude was low. Both older groups demonstrated slowed sensory reweighting over prolonged time periods when the stimulus amplitude was high. The combination of higher vision gains and slower down weighting in older adults suggest deficits that may contribute to postural instability.     

Ownership Status and the Representation of Assets of Uncertain Value: The Balloon Endowment Risk Task (BERT)

Owners tend to overvalue possessions relative to non‐owners: a phenomenon known as the endowment effect. In three experiments, using markets for goods of uncertain value, we investigated whether this can be partly attributed to misperceiving an asset's profitability or to uncertainty about a good's utility. To test our hypotheses, we devised the Balloon Endowment Risk Task, in which participants can sell or buy their right to participate in the Balloon Analogue Risk Task. Once purchased/retained, a virtual balloon is pumped to accrue money, which is lost if the balloon bursts. Participants first learn about the risky asset (balloon) by observing others playing the Balloon Analogue Risk Task before they enter the market. In Experiment 1, we replicated the endowment effect; yet, owners and non‐owners predicted pumping the same number of times and subsequently did so when given that opportunity. In Experiments 2 and 3, the level of uncertainty about the balloon's profitability was manipulated by modifying the number of bursts that participants viewed in the initial learning stage. When more diagnostic information was provided, making the average burst point easier to estimate and reducing value uncertainty and increasing confidence in valuation, the endowment effect diminished although mean estimates of the average burst point did not differ between owners and non‐owners. Thus, endowment effects were partly attributable to value uncertainty but could not be explained by owners and non‐owners having divergent perceptions of the asset's payoff distribution.

Obese, older adults with knee osteoarthritis: weight loss, exercise, and quality of life.

This study examined the effects of dietary weight loss and exercise on the health-related quality of life (HRQL) of overweight and obese, older adults with knee osteoarthritis. A total of 316 older men and women with documented evidence of knee osteoarthritis were randomly assigned to 1 of 4 18-month interventions: dietary weight loss, exercise, dietary weight loss and exercise, or healthy lifestyle control. Measures included the SF-36 Health Survey and satisfaction with body function and appearance. Results revealed that the combined diet and exercise intervention had the most consistent, positive effect on HRQL compared with the control group; however, findings were restricted to measures of physical health or psychological outcomes that are related to the physical self.
