Intra-individual variability in gait and in cognitive performance are not related in the elderly

As humans age, the amount of intra-individual variability (IIV) present in both their gait and their cognitive performance tends to increase. Both gait and cognitive IIV are associated with attentional control and with cerebrovascular disease, suggesting that the IIV in gait and cognitive function should be strongly correlated in the elderly. In this study temporal gait variability was determined from a 60-second period of walking. Cognitive variability was determined from two decision-time tasks assessing inhibition. Despite the presence of substantial amounts of gait and cognitive IIV in 71 elderly individuals, there were no significant correlations between measures of cognitive and gait IIV, suggesting that different factors drive IIV in the motor and cognitive performance of older individuals. These results are not consistent with the common cause theory of aging, which predicts that cognitive and sensorimotor performance should show related declines due to age-related disruption of a common neurological substrate.     

Biases in social comparative judgments: the role of nonmotivated factors in above-average and comparative-optimism effects

Biases in social comparative judgments, such as those illustrated by above-average and comparative-optimism effects, are often regarded as products of motivated reasoning (e.g., self-enhancement). These effects, however, can also be produced by information-processing limitations or aspects of judgment processes that are not necessarily biased by motivational factors. In this article, the authors briefly review motivational accounts of biased comparative judgments, introduce a 3-stage model for understanding how people make comparative judgments, and then describe how various nonmotivational factors can influence the 3 stages of the comparative judgment process. Finally, the authors discuss several unresolved issues highlighted by their analysis, such as the interrelation between motivated and nonmotivated sources of bias and the influence of nonmotivated sources of bias on behavior.     

An exploration of prevalence of domestic violence in same-sex relationships

The prevalence of domestic violence in a sample of 33 men and 33 women currently or previously in same-sex relationships was assessed. Data were collected through a mail survey in the state of Virginia. Of 1000 surveys sent out 66 usable ones were returned (response rate = 6.6%). Analysis indicated that 34 had experienced some form of domestic violence, but significant differences between male and female respondents were not detected. When data from this same-sex sample were compared with those of the heterosexual sample of the National Violence Against Women Survey, intimate partner assault may be more prevalent against gay men than against heterosexual men, but there was no significant difference between lesbians and heterosexual females.     

Misperceptions in intergroup conflict. Disagreeing about what we disagree about

Two studies examined misperceptions of disagreement in partisan social conflicts, namely, in the debates over abortion (Study 1) and politics (Study 2). We observed that partisans tend to exaggerate differences of opinion with their adversaries. Further, we found that perceptions of disagreement were more pronounced for values that were central to the perceiver's own ideology than for values that were central to the ideology of the perceiver's adversaries. To the extent that partisans assumed disagreement concerning personally important values, they were also inaccurate in perceiving their adversaries' actual opinions. Discussion focuses on the cognitive mechanisms underlying misperceptions of disagreement and strategies for reducing intergroup conflict.     

Secularisation,Wales, and Islam

Islam has a long, albeit hidden history in Wales. Traditionally, studies of Welsh religion have focused on Christianity so that little has been written about non-Christian religions in Wales. Moreover, general theoretical debates about secularisation have tended to be overly Christocentric in their focus, with the experiences of non-Christian faith groups conspicuous by their absence in most studies of modern urban societies and secularisation. Similarly, most academic studies emanating from Islam, while they have much to say on liberal secular societies, have yet meaningfully to engage with the secularisation thesis. This article explores the relationship between classical theories of secularisation, historical processes of secularisation in Wales, and the contemporary experience of Muslim groups operating within a highly secularised environment. The article argues that there is a need in multi-cultural societies to develop a theory of secularisation that can incorporate a non-Christian dimension. Recent theoretical writing by Steve Bruce (Politics) and David Martin (Revised Theory) offers a promising route in this direction.     

A cybernetic theory of morality and moral autonomy

Human morality may be thought of as a negative feedback control system in which moral rules are reference values, and moral disapproval, blame, and punishment are forms of negative feedback given for violations of the moral rules. In such a system, if moral agents held each other accountable, moral norms would be enforced effectively. However, even a properly functioning social negative feedback system could not explain acts in which individual agents uphold moral rules in the face of contrary social pressure. Dr. Frances Kelsey, who withheld FDA approval for thalidomide against intense social pressure, is an example of the degree of individual moral autonomy possible in a hostile environment. Such extreme moral autonomy is possible only if there is internal, psychological negative feedback, in addition to external, social feedback. Such a cybernetic model of morality and moral autonomy is consistent with certain aspects of classical ethical theories.     

Tops are more salient than bottoms

Past research has verified that observers assume that objects are reliably oriented with respect to a gravitationally centered coordinate system. Observers also appear to attend more to specific parts of objects, like faces, that typically are closer to the top. In the present work, we explored whether or not observers have a generic bias to view tops as being more salient than bottoms. In three experiments, observers indicated whether random shapes appeared to be more similar to comparison shapes that shared identical tops rather than bottoms. Observers exhibited a reliable tendency to match figures with similarly shaped tops. Matching choice was also a function of global shape attributes such as axis of elongation or size. The findings are consistent with the notion that, in nature, tops tend to be the most visible part and to provide the best information with respect to important aspects of objects such as animal intentionality and artifact functionality.
