Developmental changes in the effect of inversion: using a picture book to investigate face recognition.

Abstract: A novel child-oriented procedure was used to examine the face-recognition abilities of children as young as 2 years. A recognition task was embedded in a picture book containing a story about two boys and a witch. The story and the task were designed to be entertaining for children of a wide age range. In eight trials, the children were asked to pick out one of the boys from amongst eight distractors as quickly as possible. Response-time data to both upright and inverted conditions were analysed. The results revealed that children aged 6 years onwards showed the classic inversion effect. By contrast, the youngest children, aged 2 to 4 years, were faster at recognising the target face in the inverted condition than in the upright condition. Several possible explanations for this 'inverted inversion effect' are discussed.

Are There Ethnic Differences in Positive Body Image Among Female British Undergraduates

Abstract: Numerous studies have examined ethnic differences in body image, although the literature has tended to focus on a negative orientation toward one’s body. The present study examined whether there were differences in positive body image among 131 Caucasian, 122 South Asian, 67 African Caribbean, and 67 Hispanic female undergraduates in Britain. Participants completed several scales measuring body appreciation, societal influence on body image, and self-esteem. Results showed that, after controlling for age, Hispanic women had the highest body appreciation scores, followed by African Caribbean, Caucasian, and South Asian women, respectively. Results also showed that Hispanics had the lowest score on media influence and the highest self-esteem. Finally, regressional analyses showed that self-esteem was a strong predictor of body appreciation, over-and-above ethnic affiliation. These results are discussed in relation to the extant literature on ethnic differences in body image.

Peripheral nerves in the rat exhibit localized heterogeneity of tensile properties during limb movement.

Abstract: Peripheral nerves in the limbs stretch to accommodate changes in length during normal movement. The aim of this study was to determine how stretch is distributed along the nerve relative to local variations in mechanical properties. Deformation (strain) in joint and non-joint regions of rat median and sciatic nerves was measured in situ during limb movement using optical image analysis. In each nerve the strain was significantly greater in the joint rather than the non-joint regions (2-fold in the median nerve, 5- to 10-fold in the sciatic). In addition, this difference in strain was conserved in the median nerve ex vivo, demonstrating an in-built longitudinal heterogeneity of mechanical properties. Tensile testing of isolated samples of joint and non-joint regions of both nerves showed that joint regions were less stiff (more compliant) than their non-joint counterparts with joint: non-joint stiffness ratios of 0.5 ± 0.07 in the median nerve, and 0.8 ± 0.02 in the sciatic. However, no structural differences identified at the light microscope level in fascicular/non-fascicular tissue architecture between these two nerve regions could explain the observed tensile heterogeneity. This identification of localized functional heterogeneity in tensile properties is particularly important in understanding normal dynamic nerve physiology, provides clues to why peripheral nerve repair outcomes are variable, and suggests potential novel therapeutic targets.
