Relations among media influence,body image,eating concerns,and sexual orientation in men: A preliminary investigation

The current study explored the relation between sexual orientation, media persuasion, and eating and body image concerns among 78 college men (39 gay; 39 straight). Participants completed measures of sexual orientation, eating disorder symptoms, appearance-related anxiety, perceived importance of physical attractiveness, perceptions of media influence, and media exposure. Gay men scored significantly higher on drive for thinness, body dissatisfaction, and body image-related anxiety than their straight counterparts. Additionally, perceptions of media influence were higher for gay men, and significantly mediated the relation between sexual orientation and eating and body image concerns. Sexual orientation also moderated the relation between perceived media influence and beliefs regarding the importance of physical attractiveness, as this relation was significant for gay men, but not straight men. The current findings suggest that gay men's increased vulnerability to media influence partially accounts for the relatively high rate of eating pathology observed in this population.     

Indices of Laterality in Turner Syndrome

The present study explored the utility of manual laterality in predicting verbal and visual-spatial functioning and educational placement among girls and adolescents with Turner syndrome (TS). A significant curvilinear relationship emerged between derived Performance Intelligence Quotient (PIQ) and motor skill laterality such that either very strong or very weak laterality was less advantageous for visual-spatial skills than moderate laterality. A significant negative correlation, but no curvilinear relation, emerged between derived Verbal Intelligence Quotient (VIQ) and degree of motor skill laterality, with more strongly lateralized participants showing lower verbal skills than weakly lateralized participants. Hand preference category showed no significant relationships with VIQ, PIQ, or educational placement.     

Recognition accuracy and reaction time of vocal expressions of emotion by African-American and Euro-American college women

This study examined the relationship of racial group membership and vocal expressions of emotion. Recognition accuracy and reaction time were examined using the Diagnostic Assessment of Nonverbal Accuracy 2 Receptive Paralanguage subtests with 18 young Euro-American and African-American women. Participants listened to Euro-American children and adults speaking a neutral sentence, and identified the emotion as happy, sad, angry, or fearful. Analysis identified a significant effect for race on reaction time. Euro-American participants had faster mean RT than the African-American women for the recognition of vocal expression of emotion portrayed by Euro-Americans. However, no significant differences were found in mean accurate identification between the two groups. The finding of a significant difference in recognition RT but not in accuracy between the stimuli spoken by an adult and a child was unexpected. Both racial groups had faster mean RT in response to vocal expression of emotion by children.     

Memory for events and locations obtained in the context of elicited imitation: evidence for differential retention in the second year of life

Previous research has suggested that infants may have more robust memory for past experiences relative to memory for locations that have been encountered previously. This assertion, however, primarily results from the comparison of data that were collected using different experimental procedures. In the present study, we examined memory for events and memory for locations in the context of elicited imitation. Specifically, 13-, 16-, and 20-month-old infants were tested for long-term memory for events and locations after between-subjects delays of 1, 3, 6, 9, and 12 months. The results indicated that the event memory was retained over lengthier delays relative to the location memory, despite superior encoding of location information. The possible adaptive significance of long-term memory for events ontogenetically preceding long-term memory for locations is discussed.     

SenseCam, imagery and bias in memory for wellbeing

Identifying and modifying the negative interpretation bias that characterises depression is central to successful treatment. While accumulating evidence indicates that mental imagery is particularly effective in the modification of emotional bias, this research typically incorporates static and unrelated ambiguous stimuli. SenseCam technology, and the resulting video-like footage, offers an opportunity to produce training stimuli that are dynamic and self-relevant. Here participants experienced several ambiguous tasks and subsequently viewed SenseCam footage of the same tasks, paired with negative or positive captions. Participants were trained to use mental imagery to inter-relate SenseCam footage and captions. Participants reported increased levels of happy mood, reduced levels of sad mood, and increased task enjoyment following SenseCam review with positive versus negative captions. This shift in emotional bias was also evident at 24-hour follow-up, as participants recollected greater task enjoyment for those tasks previously paired with positive captions. Mental imagery appears to play an important role in this process. These preliminary results indicate that in healthy volunteers, SenseCam can be used within a bias modification paradigm to shift mood and memory for wellbeing associated with performing everyday activities. Further refinements are necessary before similar methods can be applied to individuals suffering from subclinical and clinical depression.     

The role of encoding strategies in the verbal memory performance in patients with schizophrenia

Background. Verbal learning and memory is often compromised in patients with schizophrenia who prefer encoding words in order of their presentation (serial clustering) rather than using semantic categories (semantic clustering). Method. One hundred and four in‐patients with schizophrenia were assessed twice with the California Verbal Learning Test. Results. Patients showed significantly less semantic than serial clustering at both assessment times. Usage of encoding strategies were not stable over time. An increase in semantic clustering improved recall and recognition performance. Conclusions. Patients with schizophrenia should be taught to use the more effective encoding strategy of semantic clustering in order to improve their memory performance.     

Thermal sensitivity and cardiovascular reactivity to stress in healthy males

This paper examines the association of cardiovascular reactivity with thermal thresholds (detection and unpleasantness). Heart period (HP), systolic (SBP) and diastolic (DBP) blood pressure of 42 health young males were recorded during a cardiovascular reactivity task (a videogame based upon Sidman's avoidance paradigm). Thermal sensitivity, assessing detection and unpleasantness thresholds with radiant heat in the forearm was also estimated for participants. Participants with differential scores in the cardiovascular variables from base line to task > or = P65 were considered as reactors and those how have differential scores < or = P35 were considered as non-reactors. Significant differences were observed between groups in the unpleasantness thresholds in blood pressure (BP) but not in HP. Reactors exhibited significant higher unpleasantness thresholds than non-reactors. No significant differences were obtained in detection thresholds between groups.     

Understanding the real value of fractions and decimals

Understanding fractions and decimals is difficult because whole numbers are the most frequently and earliest experienced type of number, and learners must avoid conceptualizing fractions and decimals in terms of their whole-number components (the "whole-number bias"). We explored the understanding of fractions, decimals, two-digit integers, and money in adults and 10-year-olds using two number line tasks: marking the line to indicate the target number, and estimating the numerical value of a mark on the line. Results were very similar for decimals, integers, and money in both tasks for both groups, demonstrating that the linear representation previously shown for integers is also evident for decimals already by the age of 10. Fractions seem to be "task dependent" so that when asked to place a fractional value on a line, both adults and children displayed a linear representation, while this pattern did not occur in the reverse task.     

Positivity can cue familiarity

Given that familiarity is closely associated with positivity, the authors sought evidence for the idea that positivity would increase perceived familiarity. In Experiment 1, smiling and thus positively perceived novel faces were significantly more likely to be incorrectly judged as familiar than novel faces with neutral expressions. In Experiment 2, subliminal association with positive affect (a positively valenced prime) led to false recognition of novel words as familiar. In Experiment 3, validity judgments, known to be influenced by familiarity, were more likely to occur if participants were in happy mood states than neutral mood states. Despite their different paradigms and approaches, the results of these three studies converge on the idea that, at least under certain circumstances, the experience of positivity itself can signal familiarity, perhaps because the experience of familiarity is typically positive.
