Personality and the response to predation risk: effects of information quantity and quality

Within aquatic ecosystems, chemosensory cues provide valuable public information regarding the form and degree of risk, allowing prey to make informed behavioural decisions. Such cues, however, may vary in both relative concentration detected (i.e. ‘quantity’) and reliability of the information available (i.e. ‘quality’), leading to varying response patterns. Moreover, prey species are also known to exhibit consistent behavioural tactics towards managing risk (i.e. personality), possibly shaping their use of public information. Here, we present two experiments examining the potential interacting effects of personality and the quantity (Experiment 1) or quality (Experiment 2) of public information on the short-term predator avoidance responses of wild-caught Trinidadian guppies under semi-natural conditions. Our first experiment demonstrated that personality shaped responses to a high concentration of alarm cues (high risk), with shyer guppies exhibiting stronger antipredator responses than bolder guppies. When exposed to either low risk or stream water controls, personality had no effect on the intensity of response. Our second experiment demonstrated that personality again shaped the response to high concentrations of alarm cues (a known risk) but not to a novel chemosensory cue (tilapia odour). When exposed to the unknown novel cue, guppies exhibited a relatively high intensity antipredator response, regardless of personality. Combined, our results suggest that individual risk-taking tactics shape the use of public information in a context-dependent fashion.     

Patient and spouse perceptions of the patient's heart disease and their associations with received and provided social support and undermining

Numerous empirical studies have investigated the relationships between cardiovascular diseases (CVD) and patients’ psychological well-being, with a focus almost exclusively on its dark side. Very little is known on the impact of illness severity on both negative and positive indicators of patients’ well-being, as well as on the psychosocial variables that may mediate this association. Aim of the study was to investigate the impact of illness severity on depression as well as on health satisfaction and life satisfaction of patients undergoing a cardiovascular rehabilitation. It also aimed at testing the mediation of illness perception and self-efficacy beliefs in managing cardiac risk factors. The study involved 172 patients (mean age?=?66.43?years; SD?=?9.99?years; 76.2% men). Illness severity was measured in terms of left ventricular ejection fraction at discharge from the cardiology department, whereas all psychological dimensions were assessed one week later. Results showed significant relationships among illness severity, depression and health satisfaction that were fully mediated by illness perception and self-efficacy beliefs, but not significant relation between disease severity and life satisfaction (χ ²(1)?=?2.30, p?=?n.s.). Overall, findings underline the importance of working on illness perception and self-efficacy beliefs to contrast depression and to improve health and life satisfaction in patients with CVD.     

Procrastination's Impact in the Workplace and the Workplace's Impact on Procrastination

Procrastination is a self‐regulatory failure, whose costs are debated. Here, we establish its impact in the workplace. Using an Internet sample, we assessed 22,053 individuals in terms of their sex, employment status, employment duration, income, occupational attainment and level of procrastination. High levels of procrastination is associated with lower salaries, shorter durations of employment, and a greater likelihood of being unemployed or under employed rather than working full‐time. Also, procrastination partially mediates sex's relationship with these work variables. Women tend to procrastinate less than men, evidently giving women an employment advantage. If women procrastinated the same as men, there should be 1.5 million fewer women in full‐time employment in the US. alone. Determining the causes of procrastination in the workplace, we also examined it at an occupational level. The results strongly support the gravitational hypothesis: jobs that require higher levels of motivational skills are less likely to retain procrastinators. However, there was some support that jobs can foster procrastination. Procrastinators tend to have jobs that are lower in intrinsically rewarding qualities.     

Shame and guilt and their relationship to positive expectations and anger expressiveness

College students (174 females, 91 males) completed measures of shame, guilt, expectations for future success, and styles of anger expression. Significant gender differences were found in proneness for both shame and guilt, with young women exhibiting a greater propensity for shame and guilt than young men. For both females and males, however, shame-proneness was positively related to expressions of inward anger. Among males and females, guilt-proness was negatively related to outward anger, but positively related to anger control. For females, guilt-proness was also negatively related to expectations for future success. Multiple regression analyses indicated that for male and female late adolescents, the best positive predictor of shame-proneness was inward anger. Gender differences emerged in predicting guilt-proneness; greater anger control, lower outward anger, and lower expectations for future success significantly predicted this variable among females.     

Personality and work motivation

A total of 92 job applicants completed the Eysenck Personality Profiler (EPP) which measures the three primary (superfactor) traits (as well as 21 second-order factors), and the Work Values Questionnaire, which requires subjects to rate how important various work factors were to them when considering applying for a job. These work factors were then categorised into the traditional Herzberg classification of Hygiene and Motivation factors, each with a satisfactory internal reliability. Correlational and regressional analyses showed that extraverts stressed the importance of motivation factors to them, while neurotics rated hygiene factors as more important to them in choosing a particular job. Psychoticism was marginally related to the hygiene factor, as was test-taking style. In view of the fact that personality factors appeared to account for between 20 and 30% of the variance in work performance, it is surprising that they have been neglected, until recently, in the organisational psychology literature.     

Psychometric validation of two Procrastination inventories for adults: Arousal and avoidance measures

Lay's (1986) General Procrastination (GP) and McCown and Johnson's (1989) Adult Inventory for Procrastination (AIP) measures were evaluated across two studies. In Study 1, both inventories were administered to two groups of college students (Sample 1 n=52; Sample 2 n=59), who were asked to return completed scales before the end of the semester. Students' attendance rates at study groups, test grades, and time required to complete multiple choice items on two exams also were recorded. Results indicated that high procrastination scores were related to a higher number of days to return completed inventories but not attendance, exams scores, or test-taking time. In Study 2, nontraditional age university students (n=215) were asked to complete procrastination measures as well as sensation-seeking, need for cognition, and self-esteem inventories. Factor analysis indicated that scores on Lay's (1986) scale loaded on sensation-seeking, while McCown and Johnson's (1989) scale loaded negatively with need for cognition and self-esteem variables. It would appear that although the scales assessed procrastinatory behavior, one inventory is indicative of sensation-seeking and the other the avoidance of poor self-esteem.Data for Study 1/Sample 1 and Study 2 were collected when the author was a Visiting Assistant Professor at Baruch College/CUNY. The author thanks instructors for permitting class time to be devoted to the data collection process. Also, the author thanks Bill McCown and Clarry Lay for editing an early draft of this paper.     

Moral affect and cognitive processes: Differentiating shame from guilt among men and women

Men (n = 103) and women (n = 183) completed measures of shame, guilt, self-critical cognitions, and perfectionism in order to explore gender differences in cognitive processes associated with moral affect. Women reported significantly higher rates of shame and guilt than men. Separate factor analyses for gender indicated that for men, shame loaded with self-critical cognitions while guilt loaded with dimensions of perfectionism. For women, both shame and guilt loaded with self-critical cognitions, but only socially-prescribed perfectionism. Results suggest that a person's gender may need to be considered in evaluations of shame and guilt.     

Why is Gandhi Wise? A Cross-Cultural Comparison of Gandhi as an Exemplar of Wisdom

This study explores cross-cultural differences in why Mohandas (Mahatma) Gandhi is nominated as an historical exemplar of wisdom. We compare the answers of emerging adults (aged 18–30) from three populations: Indian citizens, Canadian citizens, and Indian immigrants to Canada. Chi-square analyses showed that these groups emphasize significantly different aspects of Gandhi’s wisdom: Canadian citizens see Gandhi’s wisdom as practical and intellectual; Indian citizens see Gandhi’s wisdom as practical and benevolent; Indian immigrants to Canada consider Gandhi to integrate benevolent, intellectual, and practical aspects of wisdom; they also differ significantly in attributes associated with their implicit theory about his wisdom. Participants who know more about Gandhi also claim that he had a greater impact on their own lives. These findings suggest that historical exemplars of wisdom are filtered through the sociocultural contexts of each participant’s own lived experience, but that they still can be an inspiration in personally meaningful ways.
