Great apes' (Pan troglodytes, Pan paniscus, Gorilla gorilla, Pongo pygmaeus) understanding of tool functional properties after limited experience

Primates' understanding of tool functionality has been investigated extensively using a paradigm in which subjects are presented with a tool that they must use to obtain an out-of-reach reward. After being given experience on an initial problem, monkeys can transfer their skill to tools of different shapes while ignoring irrelevant tool changes (e.g., color). In contrast, monkeys without initial training perform poorly on the same tasks. Compared to most monkeys, great apes show a clear propensity for tool using and may not require as much experience to succeed on tool functionality tasks. We investigated this question by presenting 171 apes (Pan troglodytes, Pan paniscus, Gorilla gorilla, and Pongo pygmaeus) with several tool-use problems without giving them initial training or familiarizing them with the test materials. Apes succeeded without experience, but only on problems based on basic properties such as the reward being supported by an object. However, only minimal experience was sufficient to allow them to quickly improve their performance on more complex problems in which the reward was not in contact with the tool.     

A qualitative investigation of Muslim and Christian women's views of religion and feminism in their lives

This qualitative investigation explored a relatively understudied aspect of cultural diversity: feminism and religion in the lives of religiously diverse women. More specifically, structured interviews were used to investigate views of religion, women's issues, gender roles, culture, and feminism for a small group of Muslim and Christian women living in the United States. The data were analyzed using consensual qualitative research methods (Hill, Thompson, & Williams, 1997). Findings indicated a complex relationship between feminism, gender roles, culture, and religion for these women with the majority of the Muslim women reporting that their religion supports feminist principles and identifying themselves as feminist. Christian women were less willing to endorse the feminist label. Implications for multicultural feminist practice are discussed.     

Cognitive,affective and conative responses to visual simulation: the effects of rotation in online product presentation

• Rotation, one type of visual simulation used to create three‐dimensional (3‐D) experiences, and currently being used for product presentation on some e‐tail websites, may create consumer responses. Therefore, the purpose of this study is to examine the effects of rotation in product presentation on the cognitive, affective, and conative responses of consumers. This study employed a single‐factor between‐subjects design: product presentation (rotating vs. non‐rotating). Causal model analysis showed the influence of rotation in product presentation on perceived information quantity, mood, attitude, and purchase intention. Theoretical and managerial implications, as well as future research directions, are discussed.

Wittgenstein's rule-following paradox: How to resolve it with lessons for psychology

Four assumptions about rule-learning in mathematics continue to be central to psychology—mathematical rules are clear and exact, their applications are well defined, their learning is typically through social experiences, whose mechanisms are causal. All four are contradicted in Wittgenstein's analysis of the rule-following paradox (RFP) one of whose essential features is the normativity of mathematical rules. Although RFP is alive well in 21st century philosophy, it has received scant attention in psychology. My argument is in four parts—a brief review of rule-learning in psychology under the four assumptions; a substantial review of RFP in which they are invalidated; a confirming re-analysis in Piaget's developmental epistemology (DE) with its research-program for an empirically based interpretation of normativity; and four implications for psychology about the limits of causal models, constructivism and rules, rules and networks, novelty as inherent in mental functioning throughout human development.     

An Exploratory Study of Integrative Personality Pathology Systems and the Interpersonal Circumplex

Normative and pathological personality traits are theoretically associated with interpersonal behavior patterns and difficulties. However, little is known about relations between dimensional personality systems that integrate pathological and normative traits and social functioning. The current study explores the projections of scales from two integrative frameworks, the Dimensional Assessment of Personality Pathology and the Schedule for Nonadaptive and Adaptive Personality, onto interpersonal circumplex traits and problems. The DAPP and the SNAP demonstrated similar overall validity in predicting the interpersonal domain. Results suggest a novel framework for understanding personality—interpersonal behavior relations by categorizing scales according to their: a) minimal, b) non-specific, c) specific, and d) differential relations to interpersonal traits and problems with important implications for future research relating clinical constructs to interpersonal behavior as well as clinical assessment and behavioral predictions based on SNAP and DAPP scales.     

Lexical and semantic fluency discrepancy scores in aMCI and early Alzheimer's disease

Episodic memory is compromised in amnestic mild cognitive impairment (aMCI), but lesser deficits in other cognitive domains are also commonly observed and may be helpful in identifying this group. The relative difference in performance on lexical and semantic fluency tasks may be a sensitive and specific measure in aMCI and early Alzheimer's disease (AD). We compared four groups of participants, 35 early AD, 47 aMCI, 24 healthy controls, and 18 depressive out‐patient controls, on semantic and lexical fluency as well as other neuropsychological tests. Early AD and aMCI patients showed a distinct pattern of semantic impairment in the two fluency measures compared with the healthy and depressive controls. The findings implicate early failure of the semantic memory system in aMCI and AD and suggest that consideration of the discrepancy in performance on semantic and lexical fluency measures may help in the early identification of AD.     

Changing patterns of religious affiliation,church attendance and marriage across five areas of Europe since the early 1980s: trends and associations

This study draws on three waves of the European Values Survey (conducted between 1981 and 1984, between 1989 and 1993, and between 1999 and 2004) across five countries for which full data are available (Great Britain, Italy, the Netherlands, Northern Ireland, Spain, and Sweden) in order to address five research questions. Question one examined changes in religious affiliation. Across all five countries, the proportions of the non‐affiliated increased. Question two examined changes in church attendance. Across all five countries, the proportions of the non‐attenders increased. Question three examined changes in marital status. Across all five countries the proportions of the population checking the category ‘married’ declined, although in Spain the decline was marginal. Question four examined the association between religious affiliation and being married. The religious affiliated were more likely to be married than the non‐affiliated. Question five examined the association between church attendance and being married. Weekly attenders were more likely to be married than the non‐attenders. Overall these data support the close association between religion and marriage across five European countries (where there are very different religious climates) and support the hypothesis that changing religious values and changing family values go hand‐in‐hand.
