Matching faces and expressions in pixelated and blurred photos

Matching the emotional expressions of pairs of face photos was slower with pixelated and blurred photos than with original, untransformed photos. Matching the identities of the same face pairs was unaffected by pixelation and blurring. Because pixelation and blurring degrade higher spatial frequencies carrying edge-based information that define feature shape more than lower frequencies carrying configural properties, these findings converge with findings for line drawings and negative photos in showing that expression and face recognition processes differ in their reliance on edge-based and configural information.     

Avoidance behavior in panic disorder: the moderating influence of perceived control

The relations among anxiety sensitivity, perceived control, and agoraphobia were examined in 239 patients diagnosed with panic disorder (PD). Most patients exhibited agoraphobia accompanying their PD (98% situational avoidance; 90% experiential avoidance; and 80% endorsed interoceptive fear and avoidance). Anxiety sensitivity and perceived emotional control were associated with agoraphobia, and perceived threat control was found to moderate the relationship between anxiety sensitivity and agoraphobia. Lower levels of perceived control were associated with a stronger relationship between anxiety sensitivity and agoraphobia. Results were consistent for self-reported and clinician-rated agoraphobia. Implications for the role of perceived control in agoraphobia development and treatment are discussed.     

Up front and personal: confronting dynamics in the Family Group Conference

The Family Group Conference is a participatory model of decision making with families in child protection. It is a legal process that brings together the family, including the extended family, and the professionals in a family-led decision-making forum. Bringing together extended family and professionals to discuss child protection concerns can create a highly charged dynamic. Workers are challenged by family, family are challenged by workers, and family members challenge each other. Practice is also exposed to wider scrutiny as professionals also challenge the work. This article briefly describes the development and practice of family group conferencing as a family-centred legal process in Aotearoa, New Zealand. It then examines the findings of a study exploring the dynamics emerging from family group conference practice from the perspective of the coordinators who convene them. Family group conferencing as a family strengthening practice is discussed.     

Stability and change in children's division strategies

Age-related changes in children's performance on simple division problems (e.g., 6/2, 72/9) were investigated by asking children in Grades 4 through 7 to solve 32 simple division problems. Differences in performance were found across grade, with younger children performing more slowly and less accurately than older children. Problem size effects were also found in that children were faster and more accurate on small problems than on large problems. Two strategies changed across age, with children in Grade 4 relying heavily on the strategy of "addition" (adding the divisor until the dividend was reached) to solve the problems and children in Grades 5 through 7 relying primarily on the strategy of "multiplication" (recasting the division problem as a multiplication problem) to solve the problems. Surprisingly, the frequency of direct retrieval (retrieving the answer directly from memory) did not increase across grade and never became the dominant strategy of choice. Reasons for why retrieval use remains infrequent and age invariant are discussed. Overall, the results suggest that division is a unique operation and that the continued study of division may have implications for further understanding of how procedural and conceptual knowledge of arithmetic develops.     

The Personal Acquaintance Measure: a tool for appraising one's acquaintance with any person

The authors developed and evaluated the psychometric properties of the 18-item Personal Acquaintance Measure (PAM) and investigated how the PAM relates to self- other agreement in personality ratings. Results support that 6 factors represent the PAM (Duration, Frequency of Interaction, Knowledge of Goals, Physical Intimacy, Self-Disclosure, Social Network Familiarity), which showed evidence of internal consistency, test-retest reliability over 3 weeks, sensitivity to known group differences, discriminant validity from socially desirable responding, and convergent validity with other relationship inventories. Results also show that the PAM positively predicted self-other agreement. The authors discuss the implications of these findings for the PAM and research in person perception, although this measure may also be used in other research areas.     

Review of three tests of motor proficiency in children

The present purpose is to provide clinicians, occupational and physical therapists, and educators with a comparative analysis of three tests of motor proficiency. The Bruininks-Oseretsky Test of Motor Proficiency, Movement Assessment Battery for Children, and Tufts Assessment of Motor Performance were developed to assess the motor skills of children with developmental delays. The selection criteria, interrater reliability, reproducibility, and recommended use of each test are reported here. Recommendations for use of each test include standardization of the sample population to ensure its appropriateness.     

Lack of sex differences in knowledge of, attitudes about, and behaviors related to substance use in adolescents in a sample of high school students in the Northeastern USA

As part of an ongoing investigation, data were collected on behaviors and attitudes about substance abuse and general knowledge about substances for high school students (N = 1,103) during the 2002-2003 and 2003-2004 academic years. In preliminary analyses no meaningful sex differences were found for type or frequency of use, attitudes about substance use, or knowledge about substances. Lack of meaningful sex differences were evident even when comparisons by sex group were made within this ethnic minority population as well as within school Grades 10, 11, and 12. It is suggested that being a boy or a girl may have little to do with the American middle-class adolescents' choice to use substances. Findings should be understood to suggest possible cohort effects.     

Different spatial-relational information is used to recognise faces and emotional expressions

In a face photo in which the two eyes have been moved up into the forehead region, configural spatial relations are altered more than categorical relations; in a photo in which only one eye is moved up, categorical relations are altered more. Matching the identities of two faces was slower when an unaltered photo was paired with a two-eyes-moved photo than when paired with a one-eye-moved photo, implicating configural relations in face identification. But matching the emotional expressions of the same faces was slower when an unaltered photo was paired with a one-eye-moved photo than when paired with a two-eyes-moved photo, showing that expression recognition uses categorically coded relations. The findings also indicate that changing spatial-relational information affects the perceptual encoding of identities and expressions rather than their memory representations.     

Medical Decision-Making: An Argument for Narrative and Metaphor

This study examines the processes ofdecision-making used by intensive care(critical care) specialists. Ninety-ninespecialists completed a questionnaire involvingthree clinical cases, using a novel methodologyinvestigating the role of uncertainty andtemporal-related factors, and exploring a rangeof ethical issues. Validation and triangulationof the results was done via a comparison studywith a medically lay, but highly informed groupof 37 law students. For both study groups,constructing reasons for a decision was largelyan interpretative and imaginative exercise thatwent beyond the data (as presented), commonlyresulting in different reasons supporting thesame conclusions and similar reasons supportingopposite conclusions. The skills of ethicalimagination and interpretation were related toan individual's prior lived experience,construed in the broadest sense. Application ofthese skills of ethical imagination andinterpretation always occurred, to some degree,in a state of uncertainty and almost alwaysinvolved temporal relationships.Using these results, a theory of ethicaldecision-making is proffered. Three levels ortypes of reasoning processes may be present.Type I decision-making involves the applicationof rules, usually in a deductive fashion. TypeII decision-making is characterised by aprocess where a plurality of reasons arebalanced, weighed and sifted with each other.Type III decision-making is intimately linkedwith respondents lived experiences and `crafts'the content of type I and II reasoningprocesses, via the application of ethicalimagination and interpretation. Relationshipsbetween these three types of reasoningprocesses, and with narrative ethics, are alsodiscussed.
