Assessing cognitive impairment in Indigenous Australians: Re‐evaluation of the Kimberley Indigenous Cognitive Assessment in Western Australia and the Northern Territory

The Kimberley Indigenous Cognitive Assessment (KICA) was initially developed and validated as a culturally appropriate dementia screening tool for older Indigenous people living in the Kimberley. This paper describes the re‐evaluation of the psychometric properties of the cognitive section (KICA‐Cog) of this tool in two different populations, including a Northern Territory sample, and a larger population‐based cohort from the Kimberley. In both populations, participants were evaluated on the KICA‐Cog tool, and independently assessed by expert clinical raters blinded to the KICA scores, to determine validity and reliability of dementia diagnosis for both groups. Community consultation, feedback and education were integral parts of the research. for the Northern Territory sample, 52 participants were selected primarily through health services. Sensitivity was 82.4% and specificity was 87.5% for diagnosis of dementia, with area under the curve (AUC) of .95, based on a cut‐off score of 31/32 of a possible 39. for the Kimberley sample, 363 participants from multiple communities formed part of a prevalence study of dementia. Sensitivity was 93.3% and specificity was 98.4% for a cut‐off score of 33/34, with AUC = .98 (95% confidence interval: 0.97–0.99). There was no education bias found. The KICA‐Cog appears to be most reliable at a cut‐off of 33/39.     

Transmission Failure Explained1

In this paper I draw attention to a peculiar epistemic feature exhibited by certain deductively valid inferences. Certain deductively valid inferences are unable to enhance the reliability of one’s belief that the conclusion is true—in a sense that will be fully explained. As I shall show, this feature is demonstrably present in certain philosophically significant inferences—such as GE Moore’s notorious ‘proof’ of the existence of the external world. I suggest that this peculiar epistemic feature might be correlated with the much discussed phenomenon that Crispin Wright and Martin Davies have called ‘transmission failure’—the apparent failure, on the part of some deductively valid inferences to transmit one’s justification for believing the premises.     

Partly versus Completely Out of Your Mind: Effects of Incubation and Distraction on Resolving Fixation

Incubation has long been proposed as a mechanism in creative problem solving (Wallas, 1926). A new trial‐by‐trial method for observing incubation effects was used to compare the forgetting fixation hypothesis with the conscious work hypothesis. Two experiments examined the effects of incubation on initially unsolved Remote Associates Test (RAT) problems. Following exposure to misleading clues designed to induce initial fixation on RAT problems, versus no clues, participants were retested on problems either immediately after their first attempt (no‐incubation), or after a 40‐second incubation period. Resolution of initially unsolved RAT problems (fixated versus non‐fixated) was examined as a function of complete interruption (Experiment 1) or partial distraction (Experiment 2). An incubation effect, that is, better resolution of initially unsolved problems retested after a delay rather than retesting immediately, was seen only in Experiment 1, in which unsolved problems were completely removed from sight. Furthermore, an incubation effect was found only for initially fixated problems, and not for problems that were not accompanied by misleading clues. The results are consistent with the forgetting fixation hypothesis (Smith & Blankenship, 1989), which states that putting unsolved problems completely out of mind allows initial fixation to dissipate, and the results indicate that the opportunity for some conscious work during incubation periods may not be optimal for resolving fixation.     

Conservatism,Feminism, and Elizabeth Fox‐Genovese

This paper is a philosophical reconstruction of Elizabeth Fox‐Genovese's thinking about women and feminism, and an inquiry into whether there is a conservative form of feminism. The paper argues that Fox‐Genovese's endorsement of conventional social forms (like traditional marriage, motherhood, and sexual morality) contrasts strongly with feminism's criticism of these forms, and feminism's claim that they should be transformed. The paper concludes, however, that one need not call Fox‐Genovese's thought “feminist” to recognize it as serious advocacy on behalf of women and to include it in discussions about what is good for women.     

Proximity Matters: Exploring Relationships Among Neighborhoods, Congregations, and the Residential Patterns of Members

Using the Philadelphia Congregations Census, the Neighborhood Change Database, the U.S. Census, and geographic information systems (GIS) software, this study compared characteristics of congregations made up of members who live nearby their congregation's building to those with more members who commute from outside the immediate area or outside the city. We considered whether the neighborhood characteristics in which the "commuter" versus "resident" congregations were located differed in regard to racial composition, socioeconomic status, and residential stability. The study found that where the pastor lives in relation to the building, denomination, racial composition of membership, and the stability of the neighborhood were related to members' residential proximity to the congregation building.     

Vague Singulars,Semantic Indecision,and the Metaphysics of Persons*

Composite materialism, as I will understand it, is the view that human persons are composite material objects. This paper develops and investigates an argument, The Vague Singulars Argument, for the falsity of composite materialism. We shall see that cogent or not, the Vague Singulars Argument has philosophically significant ramifications.     

Age‐related variations and sex differences in gender cleavage during middle childhood

Gender cleavage, the segregation of the sexes, is a powerful phenomenon affecting socialization during childhood, but its developmental trajectory is far from clear. Sociometric responses by 299 boys and girls in Grades 3 to 6 from a group preference record were used to investigate age‐related variations and sex differences in gender cleavage. Moreno's (1953) developmental model of gender cleavage was examined in the light of sociocultural changes, as well as advances in the theory and measurement of gender cleavage. Sex differences were found in same‐gender preference, with older elementary girls showing greater same‐gender preference than boys of the same age. However, this finding, plus the absence of gender differences in cross‐gender evaluations, did not support more recent developmental accounts of gender cleavage. Linear trend analyses contradicted Moreno's basic precept of increasing same‐gender preference between Grades 3 and 6. While same‐gender acceptance and rejection were relatively similar regardless of grade level, cross‐gender acceptance was greater in higher than in lower grades and the reverse was true for rejection. Furthermore, weaker gender cleavage effects in rejection data than in acceptance data suggested that strong same‐gender liking does not infer equally robust cross‐gender dislike. Gender cleavage appears to be relative rather than absolute. A more complex model is proposed incorporating sex differences as well as rejection evaluations
