An exploratory investigation of coffee and lemon scents and odor identification

Fragrance sellers often provide coffee beans to their customers as a "nasal palate cleanser," to reduce the effects of olfactory adaptation and habituation. To test this idea, college students smelled three fragrances multiple times, rating odors each time. After completing nine trials, participants sniffed coffee beans, lemon slices, or plain air. Participants then indicated which of four presented fragrances had not been previously smelled; Coffee beans did not yield better performance than lemon slices or air.     

Adaptation may cause some of the face caricature effect

One of the ways to demonstrate a caricature preference is to ask participants to adjust a face image over a range from anti-caricature to caricature until it shows the best likeness to a specific individual. Since facial adaptation, whereby exposure to a face influences subsequent perception of faces, is rapid, it is possible that adaptation promotes the selection of a caricatured image. We tested whether giving participants a reference average face image, to counteract any adaptation, would reduce the degree of caricature selected for famous faces. Results confirmed a significant decrease but, even without an average, participants chose an anti-caricatured image. These data suggest a role for adaptation in generating caricature preferences while also suggesting such preferences are not inevitable.     

A male advantage for spatial and object but not verbal working memory using the n-back task

Sex-related differences have been reported for performance and neural substrates on some working memory measures that carry a high cognitive load, including the popular n-back neuroimaging paradigm. Despite some evidence of a sex effect on the task, the influence of sex on performance represents a potential confound in neuroimaging research. The present study investigated sex-related differences in verbal, spatial, and common object versions of the high cognitive load "n-back" working memory task. Eighteen male and 18 female undergraduates completed all 3 versions of the task. A mixed ANOVA, with Sex (male and female) as the between-subjects factor and Condition (verbal, spatial, and object) as the within-subjects repeated measure revealed that males were significantly more accurate than females on the spatial and object versions of the n-back task and performed equivalently to females on the verbal version of the task. Although the expected female advantage for verbal working memory was not found using this effortful n-back task, these results support a male advantage for high cognitive load spatial and object working memory. Future research should take into account the influence of sex on performance of the n-back task, and examine sex-related differences in working memory using other paradigms.     

Why Do Men Benefit More from Marriage Than Do Women? Thinking More Broadly About Interpersonal Processes That Occur Within and Outside of Marriage

In this commentary we return to the original question of Wanic and Kulik??s paper, ??Why do men benefit more from marriage than do women??? We suggest that trying to understand why women suffer more than men in marriage (from conflict or for any other reason) will not, by itself, answer the question. The answers are certainly multifaceted and complex, and there is little reason to pit one possible answer against another. We highlight that when examining gender differences in health in marriage it is important to (a) consider the helpful processes in combination with hurtful ones, b) take a broad view on this question including many types of social processes, and c) consider processes that occur outside of marriage as well as those that occur inside of marriage.     

An Examination of the Psychologists' Attitudes Towards Complementary and Alternative Therapies Scale Within a Practitioner Sample

This study assessed the validity of a scale measuring psychologists' attitudes towards complementary and alternative therapies and compared the attitudes of psychologists with a previous sample of psychology students. The scale, derived from existing measures for medical professionals and previously tested on a sample of psychology students, was completed by practising psychologists (N = 122). The data were factor analysed, and three correlated subscales were identified, assessing the perceived importance of knowledge about available therapies, attitudes towards integration with psychological practice, and concerns about associated risks of use. This structure was similar, but not identical, to that found in a previous sample of psychology students; however, psychologists expressed more concern for risks associated with integration and were less likely to hold a positive attitude towards integration. This scale will be useful in gauging changes in psychologists' attitudes towards integrative practice over time.     

Children's responses to entry failure: attention deployment patterns and self-regulation skills

In this study the authors investigated associations among children's observed responses to failure in an analogue entry situation, their attention deployment patterns, and skills and processes associated with self-regulation. Participants were 54 kindergarten and first-grade students who were either aggressive-rejected or low aggressive-popular based on peer nominations. Inhibitory control predicted the tendency to respond to entry failure by stopping and watching the group's activity. Baseline vagal tone and other-directed attention predicted children's tendency to change entry strategies after failure. Parent-rated attention skills moderated the relation between children's attention deployment patterns during the entry task and their responses to entry failure. Children who engaged in more other-directed attention were less likely to turn to solitary play after entry failure but only if they had high or moderate levels of attentional control. Other-directed attention was related to repeating previous entry bids without modification after entry failure but only when children had high levels of attention problems.     

Stressful demands or helpful guidance? The role of display rules in Indian call centers

This paper utilizes conservation of resources (COR) theory and two of Hofstede's (1980) dimensions of culture (individualism and power distance) to examine the impact of display rules on job satisfaction and performance in an Indian call center sample. Contrary to findings in an American sample (Wilk & Moynihan, 2005), we proposed that due to cultural differences as well as differences in the nature of the job among representatives in an Indian call center, supervisory focus on display rules would reduce emotional exhaustion, and in turn, have positive consequences for employee performance and job satisfaction. Using multi-source data in a sample of 137 Indian call center representatives, results confirmed the hypothesized mediating effects of emotional exhaustion on performance and job satisfaction. Implications of these results for future cross-cultural research are presented.     

Heightened interpersonal security diminishes the monetary value of possessions

People may value their possessions, in part, because ownership of goods promotes feelings of security. If so, increasing their sense of security should reduce the value they place on possessions. In two studies we tested this prediction. In Study 1, participants who were assigned randomly to write about an instance of receiving social support placed less monetary value on a blanket they owned relative to participants who were assigned randomly to write about a pleasant restaurant experience. In Study 2, participants who were unobtrusively primed with security-related words placed less monetary value on a pen they just received relative to participants who were primed with positive or neutral words. Results suggest that enhancing interpersonal security reduces valuing possessions.     

Effect of viewing the interview and identification process on juror perceptions of eyewitness accuracy

This study examined whether showing jurors a video of the witness's initial attempts to describe and identify the perpetrator would facilitate jurors' ability to discriminate between accurate and inaccurate witnesses. Mock jurors observed a simulated trial in which the key witness testified under direct examination and cross‐examination. The jurors saw either the witness's testimony or the witness's testimony plus videotape footage of the earlier police interviews in which the witness described and attempted to identify the perpetrator. Results support the hypothesis: Jurors in the examination‐plus‐video condition discriminated between accurate and inaccurate witnesses better than jurors in the examination‐only condition. We discuss various mechanisms to explain the advantage provided by the video. It is recommended that police officers videotape the line‐up procedure and that jurors be shown this video at trial.

A face only an investor could love: CEOs' facial structure predicts their firms' financial performance

Researchers have theorized that innate personal traits are related to leadership success. Although links between psychological characteristics and leadership success have been well established, research has yet to identify any objective physical traits of leaders that predict organizational performance. In the research reported here, we identified leaders' facial structure as a specific physical trait that correlates with organizational performance. Specifically, we found that firms whose male CEOs have wider faces (relative to facial height) achieve superior financial performance. Decision-making dynamics within a firm's leadership team moderate this effect, such that the relationship between a given CEO's facial measurements and his firm's financial performance is stronger in firms with cognitively simple leadership teams.
