A reversal of the Stroop interference effect,through scanning:

Interference on the Stroop test has been explained on the basis of a stronger habit (word reading) interfering with a weaker one (color naming) on an incongruous color-word (CW) card. Since scanning for words is slower (weaker) than scanning for colors, it was predicted that making the Stroop a scanning task would produce more interference with scanning for words rather than colors on the CW card. This prediction was confirmed. In addition, analyses of individual differences offered some support for differential habit-strength theories of Stroop interference. However, differences between the standard and scanning Stroop tests suggested that some kind of information-processing analysis would be more fruitful.     

On a recent argument for the impossibility of a statistical explanation of single events, and a defence of a modified form of Hempel''s theory of statistical explanation

An argument has been recently proposed by Watkins, whose objective is to show the impossibility of a statistical explanation of single events. This present paper is an attempt to show that Watkins's argument is unsuccessful, and goes on to argue for an account of statistical explanation which has much in common with Hempel's classic treatment.I am very grateful to Peter Clark for many helpful discussions of these issues.     

Attention deficit,conduct, oppositional,and anxiety disorders in children: III. Laboratory differences

Children aged 5–13 years with DSM-III diagnoses of Attention Deficit (ADDH), Anxiety, (ANX), or Conduct plus ADDH (HC) Disorder and matched normal controls were compared on a set of laboratory measures of impulsivity, arousal, motor performance, activity level, and cognition, and on behavior ratings during testing. While ANX patients did not differ from their controls, ADDH and HC patients did on Verbal IQ, most of the behavior ratings, and on about one-third of the test variables. ANX patients were about 1 year older, and more likely to be female, than ADDH and HC patients. When age, sex, and verbal IQ effects were partialed out, very few differences among the three diagnostic groups remained. The importance of precise control of such variables is emphasized and the impact of the failure to do so in past studies is discussed. The question is raised whether the deficit in verbal IQ is not so much a defect of matching as the essential feature of ADDH from which most of the other commonly reported cognitive symptoms stem.This research was supported by the Medical Research Council of New Zealand.     

The sentence-verification paradigm: A case study of two conflicting aproaches to individual differences

The contrasting approaches of differential psychology and cognitive psychology to the same individual differences data are outlined. Using illustrative data from the Clark and Chase (1972) sentence-picture verification task, four loci of conflict between these two disciplines are identified. These areas of conflict center around issues of (1) theory versus measurement, (2) meaningfulness versus reliability, (3) linearity of relationships, and (4) discontinuities in performance. We conclude on the basis of observed incompatibilities that a simple derivation of differential psychology from cognitive psychology is not likely, but separate development of complementary theories may be possible.     

The leisure problem and the role of the clergy

Leisure behavior reflects a response to religious questions in that it is a matter of choice and value. The article investigates leisure as a social problem and defines it as a spiritual capacity for freedom. Historically there have been variations in the value accorded leisure in religion fostering tension between the values of work and leisure. An analysis of structural interrelations between leisure and religion suggest ways clergy may help to alter the work-leisure relation by pointing to the value of leisure and creating social oportunities for its use.     

Psychometric properties of the Chinese version of the diabetes empowerment scale

Metabolic control is central to positive clinical outcome in patients with diabetes. Empowerment has been linked to metabolic control in this clinical group. The current study sought to determine key psychometric properties of the Chinese version of the Diabetes Empowerment Scale (C-DES) and to explore the relationship of the C-DES sub-scales to metabolic control in 189 patients with a diagnosis of diabetes. Confirmatory factor analysis established that the five sub-scales of the C-DES offered a highly satisfactory fit to the data. Furthermore, C-DES sub-scales were found to have generally acceptable internal consistency and divergent reliability. However, convergent reliability of C-DES sub-scales could not be established against metabolic control. It is concluded that future research needs to address ambiguities in the relationship between empowerment and metabolic control in order to afford patients an evidenced-based treatment package to assure optimal metabolic control.     

The relative influence of facial neoteny and waist-to-hip ratio on judgements of female attractiveness and fecundity

Numerous studies have demonstrated that waist-to-hip ratio (WHR) affects perceptions of female physical attractiveness and fecundity. This study tested the assumption that facial attractiveness explained more variance in overall ratings and fecundity than WHR, when the latter is manipulated within the normal range (0.67 - 0.85). One hundred and sixty-one participants (mean age = 21.5) rated the attractiveness, youthfulness, fertility, healthiness and likelihood of being pregnant for 27 photographs of three females in which facial attractiveness in terms of neoteny (three levels) and WHR (three levels) had been systematically digitally manipulated. Facial attractiveness exerted a significant influence on judgements of attractiveness, youthfulness, fertility and healthiness, whereas WHR only affected likelihood of being pregnant. Results are interpreted in terms of neotenous facial attractiveness providing potential mates with information concerning phenotypic and genetic quality.
