More Than Just Skin Deep? Personality Information Influences Men's Ratings of the Attractiveness of Women's Body Sizes

ABSTRACT

This study examined the influence of personality information on perceptions of the physical attractiveness of a range of female body sizes. A sample of 2,157 male university students were randomly assigned to one of 10 groups in which they received personality information about women they were rating, or a control group in which they received no personality information. Controlling for participants' age and body mass index, results showed no significant between-group differences in the body size that participants found most attractive. However, participants provided with positive personality information perceived a wider range of body sizes as physically attractive compared with the control group, whereas participants provided with negative personality information perceived a narrower range of body sizes as attractive. Correlations showed that participants' own Extraversion was associated with their body size ratings. These results suggest that non-physical cues have an influence on the perception of physical beauty.     

Body weight, not facial width-to-height ratio, predicts aggression in pro hockey players

Studies indicate that facial characteristics may predict behavior, but it is unclear if this will hold within highly selective populations. One relevant characteristic is the face’s width-to-height ratio (FWHR), a sexually dimorphic trait that has been shown to predict aggression. That FWHR may predict aggression within highly selective populations was suggested by Carré and McCormick’s (2008) finding that professional hockey players with greater FWHRs accrued more penalties. We attempted to replicate this result using all NHL players. We also explored fighting penalties as another aggression measure and height and weight as additional aggression predictors. We found that body weight predicted substantial variance in aggression but FWHR did not. Thus, in highly selective populations, inferences based on faces may be inaccurate.     

New experimental test of strain-gradient plasticity theory: metal foil sandwich structures in flexure

Experimental tests of strain-gradient plasticity theory rely on studies of the size effect (smaller is stronger) in micromechanical testing. The plastic strain gradient is varied by varying the size of the specimen. This confounds the direct effects of the size and the effects of the strain gradient. We propose experiments on foil sandwich structures in which these parameters are separated. Preliminary results suggest that it is the foil thickness that determines the strength, not the strain gradient.     

Vertex interactions and film shapes in two-dimensional foam

A model of the structure of two-dimensional foam (cells separated by circular arcs (films) meeting at threefold vertices) is considered. Films that are so curved as to be nearly semicircular arcs are problematic for conventional foam structure computations, which aim to identify the pressures needed to achieve specified bubble areas. When the films have near semicircularity, tiny variations in pressure can lead to large changes in the computed bubble area, and hence a failure to meet the specified targets. A new algorithm for determining foam structure is presented. It is based on 'freezing' most of the system, except the nearly semicircular arcs, and then finding the particular bubble pressures associated with the latter via an analytic approximation. This procedure is shown to work well for structure relaxation in a small bubble cluster. Large relaxed bubble clusters are considered briefly at the end of the paper.     

Thermodynamics of void nucleation in nanoparticles

The nucleation of voids at the initial stage of hollow nanoshell formation is described in terms of the thermodynamics of nucleation in systems of finite size (or small systems) pumped with vacancies by interdiffusion-driven vacancy influx. Crossovers from suppressed nucleation to metastable nucleus formation and then to stable nucleus formation are analysed, describing, in particular, the possibility of significant supersaturations with vacancies of the metallic core. It is shown that at higher temperatures it becomes more favourable to nucleate at once a large single void instead of multiple tiny voids.     

Words in larger font are perceived as more important: explaining the belief that font size affects memory

ABSTRACT

Words presented in larger font size are considered more memorable and rated with higher judgments of learning (JOLs). One explanation for this phenomenon is that people believe that font size affects memory. However, it is not clear why people hold this belief. One alternative is that font size represents importance, with larger fonts implying more relevant information. More important information is judged as more memorable and is, in fact, better remembered. In Experiments 1 and 2 we presented words in small (18 points) and extra-large font (250 points) and found higher JOLs and higher judgments of importance with extra-large fonts. A mediation analysis showed that importance accounted for 21–23% of the effect of font size on JOLs. In Experiment 3, we tested whether processing fluency was higher with the extra-large font. In a lexical decision task, participants were slower at detecting words and non-words with extra-large than small font, which is the opposite of what the processing fluency hypothesis predicts. This result shows that the font-size effect persists even in conditions in which perceived fluency should be lower. In sum, this research explained the belief that font size affects memory because words in larger fonts are considered more important.     

The influence of anxiety on action-specific perception

Abstract

Recent empirical research suggests that performance modulates perception. For example, baseball players judge the ball to be bigger when performing well as compared to when performing less successfully. Yet, the underlying processes that mediate the emergence of action-specific effects on perception are still largely unknown. To this end, we aimed to examine the impact of anxiety on the action-specific influence on perception as anxiety has been shown to affect both performance and perception. Thirty participants threw darts at a circle-shaped target and were then asked to judge the size of the target. The task was performed under conditions of low and high anxiety. Results replicated previously reported action-specific effects on perception under levels of low anxiety. However, these effects vanished in the high anxiety condition. Results seem to suggest that anxiety has a direct influence on the relation between performance and perception. Attentional control theory is discussed to explain the current findings.     

The Impact of Size of Cooperative Group on Achievement,Social Support,and Self-Esteem

The effect of cooperative learning in pairs and groups of 4 and in individualistic learning were compared on achievement, social support, and self-esteem. Sixty-two Italian 7th-grade students with no previous experience with cooperative learning were assigned to conditions on a stratified random basis controlling for ability, gender, and self-esteem. Students participated in 1 instructional unit for 90 min for 6 instructional days during a period of about 6 weeks. The results indicate that cooperative learning in pairs and 4s promoted higher achievement and greater academic support from peers than did individualistic learning. Students working in pairs developed a higher level of social self-esteem than did students learning in the other conditions.     

Gender Differences in Body Size Dissatisfaction Among Individuals With Low,Medium, or High Levels of Body Focus

The authors designed the present study to test whether women reported higher levels of body dissatisfaction than did men even when the 2 genders were matched on a measure of degree of body focus. Sixty undergraduates (30 men, 30 women) were screened on attention-to-body-shape scores and divided into high, medium, and low body-shape-focus groups. The participants also completed questionnaires that provided information on age, education, vocabulary ability, levels of depression, and body-image assessment. The groups did not differ (ps > .05) on age, education, vocabulary ability, or levels of depression. However, women in all 3 body-shape-focus categories indicated a larger discrepancy between their real vs. ideal body images (p < .01) than did the men. In the high-body-focus group, there was an 11:1 ratio between women's and men's reported real-ideal body-shape discrepancies. Women showed greater body dissatisfaction than did men, even when the genders were matched on a measure of body focus.
