Self- and social perception of physical appearance in chest wall deformity

This study analyzes self- and social perception of physical appearance in patients with chest wall deformity (CWD), including both pectus carinatum and pectus excavatum. Self-perception of appearance in 76 patients with CWD and social perception of patients' appearance by 20 adult and 20 adolescent raters was assessed using the Appearance Rating Scale (Stangier et al., 2000) and evaluated for agreement and multivariate correlates. Results indicate no agreement between self- and social rating. Based on mean scores patients rated their appearance significantly more negatively than adult raters but only slightly different than adolescent raters. Adolescent raters' judgment of the patients' appearance was related to CWD characteristics, while self-rating rather seems to be related to psychosocial factors. Because adolescents are a relevant peer group for adolescent patients with CWD their evaluation of the appearance might influence patients' self-image and might affect their psychological functioning. Effective interventions focusing on social interactions are needed.     

Sink positive: Linguistic experience with th substitutions influences nonnative word recognition

We used eyetracking, perceptual discrimination, and production tasks to examine the influences of perceptual similarity and linguistic experience on word recognition in nonnative (L2) speech. Eye movements to printed words were tracked while German and Dutch learners of English heard words containing one of three pronunciation variants (/t/, /s/, or /f/) of the interdental fricative /θ/. Irrespective of whether the speaker was Dutch or German, looking preferences for target words with /θ/ matched the preferences for producing /s/ variants in German speakers and /t/ variants in Dutch speakers (as determined via the production task), while a control group of English participants showed no such preferences. The perceptually most similar and most confusable /f/ variant (as determined via the discrimination task) was never preferred as a match for /θ/. These results suggest that linguistic experience with L2 pronunciations facilitates recognition of variants in an L2, with effects of frequency outweighing effects of perceptual similarity.     

Brands on the brain: Do consumers use declarative information or experienced emotions to evaluate brands?

An fMRI study was conducted with unfamiliar and familiar (strong and weak) brands to assess linguistic encoding and retrieval processes, and the use of declarative and experiential information, in brand evaluations. As expected, activations in brain areas associated with linguistic encoding were higher for unfamiliar brands, but activations in brain areas associated with information retrieval were higher for strong brands. Interestingly, weak brands were engaged simultaneously in both processes. Most importantly, activations of the pallidum, associated with positive emotions, for strong brands and activations of the insula, associated with negative emotions, for weak and unfamiliar brands suggested that consumers use experienced emotions rather than declarative information to evaluate brands. As a result, brand experiences should be considered a key driver of brand equity in addition to brand awareness and cognitive associations.     

D1/D5 dopamine receptors modulate spatial memory formation

We investigated the effect of the intra-CA1 administration of the D1/D5 receptor antagonist SCH23390 and the D1/D5 receptor agonist SKF38393 on spatial memory in the water maze. When given immediately, but not 3h after training, SCH23390 hindered long-term spatial memory formation without affecting non-spatial memory or the normal functionality of the hippocampus. On the contrary, post-training infusion of SKF38393 enhanced retention and facilitated the spontaneous recovery of the original spatial preference after reversal learning. Our findings demonstrate that hippocampal D1/D5 receptors play an essential role in spatial memory processing.     

A Critical Assessment of Null Hypothesis Significance Testing in Quantitative Communication Research

Null hypothesis significance testing (NHST) is the most widely accepted and frequently used approach to statistical inference in quantitative communication research. NHST, however, is highly controversial, and several serious problems with the approach have been identified. This paper reviews NHST and the controversy surrounding it. Commonly recognized problems include a sensitivity to sample size, the null is usually literally false, unacceptable Type II error rates, and misunderstanding and abuse. Problems associated with the conditional nature of NHST and the failure to distinguish statistical hypotheses from substantive hypotheses are emphasized. Recommended solutions and alternatives are addressed in a companion article.

FRIENDLY OR SEXY?

A set of three studies replicated and extended Abbey's (1982) research, indicating that men perceive less friendliness, but more sexuality than women when observing women's social interactions. Study 1 was based on 49 previously unacquainted male-female pairs who engaged in brief face-to-face discussions, and 48 males and 61 females who observed one of those discussions. Study 2 was based on videotaped exchanges between a male store manager and a female cashier, and Study 3 between a male professor and a female student; 75 males and 88 females participated in Study 2, while 98 males and 102 females participated in Study 3. In all three studies, the men saw less friendliness, but more "sexiness" in the woman's behavior than the women. These results support the idea that some of the less severe forms of sexual harassment in business and academic settings may be better understood eventually through research and theory development that considers these sex differences in social perceptions.     

Youth Suicide Prevention: A Survey and Analysis of Policies and Efforts in the 50 States

State-level initiatives directed at youth suicide prevention since 1980 were analyzed. During 1992 and 1996, each governor was surveyed regarding his or her state's efforts in youth suicide prevention. Questions pertained to legislation, a mandated or recommended school-based suicide prevention curriculum, funding, a special advisory council, a state plan, the development and dissemination of materials, and assessment. Several states sent examples of their prevention activities, which were reviewed to determine the extent to which they represent conceptually and/or empirically grounded preventive intervention strategies. The number of suicides, suicide rates, and percentage change in rate for youth 15–19 years old were reported by state for the periods 1979–1981 and 1992–1994. The results of a repeated measures 2 × 5 ANOVA revealed that while changes in suicide rates over time were statistically significant, there was no relation between these changes and any of the variables studied. Suggestions for future research on state-level initiatives are presented.
