A new look at the relationship between perceptual and motor responses

A visual stimulus may affect a motor response although its visibility is prevented by a mask. This implies that the sensorimotor system is more susceptible to stimulation than the perceptual system. We report data that are contrary to this intuition. Experiments where both the observer's perceptual state related to the presence/absence of a masked stimulus and the motor behaviour elicited by the same stimulus were jointly assessed on a trial-by-trial basis show that masked visual stimulation at constant visibility (d′) has two types of effect on the motor system. When the physical energy of the masked stimulus is weak, it affects the motor response only if it exceeds the observer's perceptual response criterion. It is only when the physical energy of the masked stimulus is relatively strong that its impact on the motor response is independent of the state of the perceptual system. This indicates that reflex, “nonconscious” behaviour has a high energy threshold.     

The illusion of nonmediation in telecommunication: Voice intensity biases distance judgments to a communication partner

The illusion of nonmediation is an experience in mediated communication where individuals respond as if the medium is not there. It is frequently associated with advanced media technology, such as virtual environments and teleconference systems. In this paper, we investigate whether people experience an illusion of nonmediation during interactions as simple as making a phone call. In three experiments, participants were asked to listen to someone's voice on a mobile phone (Experiment 1) or through VoIP software (Experiment 2 and 3) before guessing the location of the person and indicating this location on a map. Results consistently demonstrated that louder voices were judged to be closer, as if the technical mediation was ignored. Combining the three experiments, a small-scale meta-analysis yielded an effect size estimate of d = 0.37 for the ‘louder-as-closer’ effect. Implications of the results and suggestions for future research are discussed.     

The role of media and peer influences in Australian women's attitudes towards cosmetic surgery

The study aimed to examine the influence of media and peers on attitudes towards cosmetic surgery using a sociocultural framework. A sample of 351 Australian women aged 18–69 years completed measures of media exposure, friend conversations, internalisation of appearance ideals, appearance comparison, body dissatisfaction, and attitudes towards cosmetic surgery. Correlational analysis showed that almost all media and friend variables were significantly correlated with positive attitudes towards cosmetic surgery. A structural equation model based on the sociocultural model showed a good level of fit to the data. The effects of media exposure and friend conversations on body dissatisfaction and attitudes towards cosmetic surgery were mediated by internalisation. We concluded that media exposure and friend conversations affected attitudes towards cosmetic surgery both directly and indirectly. Our results contribute to the understanding of the sociocultural mechanisms underlying women's motivations for cosmetic surgery.     

Gratitude buffers the adverse effect of viewing the thin ideal on body dissatisfaction

Gratitude has robust associations with multiple aspects of well-being. However, little research has explored whether the psychological benefits of gratitude extend to body image. We used a repeated measures experimental design to test whether a brief period of grateful reflection would buffer the adverse effect of exposure to thin-ideal media. Female undergraduates (N = 67) completed three sessions one week apart. The conditions were specifically designed to isolate (a) the effects of viewing thin models on body dissatisfaction and (b) the moderating effect of grateful contemplation. Results showed that body dissatisfaction scores were lower for women who engaged in a brief period of grateful contemplation before viewing photographs of thin models than for women who reflected upon life hassles before viewing the same photographs. The magnitude of this decrease depended on BMI. Gratitude offers an innovative direction for future research directed toward helping women to accept their bodies.     

‘Retouch free’: The effect of labelling media images as not digitally altered on women's body dissatisfaction

This study aimed to investigate the effect of ‘retouch free’ labels on thin ideal fashion images on women's body dissatisfaction. This represents an experimental analogue to current practice by some fashion magazines. Participants were 224 female undergraduates who viewed a set of fashion shoots with either no label, or a label indicating that the image had not been digitally altered. Results indicated that, although body dissatisfaction increased after exposure to the thin ideal images, there was no significant effect of label type on mood or body dissatisfaction. It was concluded that labelling images as digitally unaltered appears neither helpful nor harmful in terms of body dissatisfaction. Nevertheless, more extensive research is required to guide the most effective use of labels.     

Personalized interactive characters for toddlers' learning of seriation from a video presentation

Children's media is rooted in relationships with onscreen characters. In this study, 18-month-old toddlers were initially exposed to one of two unfamiliar interactive media characters for 3 months. Conditions varied whether the character was personalized to them or not. At age 21 months, toddlers were tested on a seriation task that was presented onscreen by the character and compared to the performance of a 21-month-old control group who did not view a video demonstration (total N = 48). Toddlers learned significantly more from the personalized character, but not from the non-personalized character, when compared to the control group. Children in the personalized condition also increased in parasocial, nurturing behaviors directed at the character during play sessions, and these scores were linked to better seriation performance. The results suggest an important role for social relationships with interactive characters to teach early seriation skills.     

Digit ratios and preferences for aggressive content in entertainment

Digit ratios (2D:4D) contain information concerning an individual’s propensity towards aggression. Our study adds the first clue to better understanding the relationship between 2D:4D and exposure to aggressive contents in entertainment products. Our findings suggest that individuals with low 2D:4D prefer aggressive contents such as action films, sports telecast, killing and achieving games, hip-hop music, and erotic video clips rather than do individuals with high 2D:4D. Also individuals with low 2D:4D tend to demonstrate less preference for romance films than individuals with high 2D:4D. In addition, we found that low 2D:4D was associated with a preference for sports instead of other genres of entertainment products. Therefore, 2D:4D (a putative correlate of prenatal sex steroids) helps us to better understand the rationale of individuals’ preferences for media violence.     

The effect of viewing ultra-fit images on college women's body dissatisfaction

Modern ideals of female attractiveness include an extremely toned and fit appearance in addition to extreme thinness. Although viewing thin models has a negative effect on women's body image, research has not tested the effect of exposure to the ultra-fit physique separate from the thin-ideal. This randomized, posttest-only experiment tested the effects of the athletic aspect of the current ideal by exposing 138 undergraduate women to thin and athletic models, normal weight athletic models, or a control condition consisting of neutral objects. The study also tested the moderating effects of thin-ideal and athletic-ideal internalization. Exposure to thin ultra-fit models, but not normal weight ultra-fit models, produced an increase in body dissatisfaction and neither internalization variable moderated this effect. Findings suggest that interventions that focus on the benefits of fitness while challenging the desirability of thinness may offer promising results.     

A comparative study of the general factor of personality in Jewish and non-Jewish populations

It was hypothesized that Jews would have a personality profile characterized by high levels of the general factor of personality (GFP). Analyses based on three large samples supported this hypothesis. Additionally, the Jewish/non-Jewish group difference on personality traits exhibited a Jensen Effect with the largest difference between groups being on the traits that had the highest loadings on the GFP. Future research should focus on investigating how the high Jewish GFP is manifested in behavioral and social outcomes.     

A structural equation model of intuitive eating with adolescents

IntroductionThe tendency to eat by paying attention and respecting the body's hunger and satiety cues is called intuitive eating. This eating behavior has been linked to positive health and well-being outcomes.ObjectiveThe purpose of this study was to test a global model linking intuitive eating with self-esteem, body esteem, media influence and including fear of negative appearance evaluation in adolescents’ boys and girls.MethodIn total, 740 adolescent high school students (51.5% girls; M age = 14, SD = 1.5) completed self-report questionnaires with measures of intuitive eating, body esteem, self-esteem, media influence and fear of negative appearance evaluation.ResultsStructural equation modeling revealed an overall excellent fit for the final four-variable model excluding the fear of negative appearance evaluation variable. Mediation analyses showed an indirect relationship between intuitive eating and body esteem via media influence, for girls but not for boys. Body esteem mediated the relationship between intuitive eating and self-esteem, for girls and boys.ConclusionA new model is proposed where intuitive eating is associated with self-esteem through body esteem and media influence. These findings suggest that regulating attitudes and behaviors toward food may be related to higher psychological well-being.
