War exposure and post-traumatic stress as predictors of Portuguese colonial war veterans' physical health

The relationship between war exposure and post-traumatic stress disorder (PTSD) has been largely investigated but the impact of the combat experience on physical health has only recently merited attention. The authors investigated the relationship between war exposure and psychological and physical health among 350 Portuguese colonial war veterans. The role of current PTSD symptoms as a mediator of these relationships was also investigated. The results showed that 39% of the veterans met criteria for current PTSD diagnosis and psychological distress was present in half of the sample. Pain, fatigue, and sleep problems were the most reported physical symptoms and mental health and gastro-intestinal problems, the most reported illnesses. Combat exposure variables were significant predictors of current health. The results indicated that veterans with higher exposure to war trauma maintained higher current levels of psychological distress and presented more physical health problems and physical symptoms than those less exposed. Mediation analyses showed that current PTSD was a full mediator of the relationship between war exposure and physical health outcomes.     

Dysfunctional body investment versus body dissatisfaction: Relations with well-being and controlled motivations for obesity treatment

In this study, we investigated the associations between body image and psychological well-being, exploring the mediating role of controlled regulation for entering obesity treatment. In addition, we analyzed whether investment body image was more strongly associated with controlled regulation (and subsequent well-being) compared to evaluative body image. These analyses were performed controlling for baseline BMI effects. Participants were 139 overweight women (age: 38.0 ± 6.7 year; BMI: 32.0 ± 4.1 kg/m²) entering treatment. Evaluative and investment body image, controlled regulation, and psychological well-being were assessed. Body image investment was positively associated with controlled regulation; evaluative body image was not. Controlled regulation was negatively associated with self-esteem and psychological functioning. Controlled regulation partially mediated the effects of body image investment on self-esteem, but did not mediate its effects on psychological functioning. Results suggest that dysfunctional body image investment might undermine well-being within overweight women, partly by increasing controlled regulation for entering obesity treatment. Discussion focuses on the importance of enhancing body image and autonomy during treatment to improve well-being and weight outcomes.     

Duration discrimination by musicians and nonmusicians

This study investigated the effects of stimulus modality, standard duration, sex, and laterality in duration discrimination by musicians and nonmusicians. Seventeen musicians (M age = 24.1 yr.) and 22 nonmusicians (M age = 26.8 yr.) participated. Auditory (1,000 Hz) and tactile (250 Hz) sinusoidal suprathreshold stimuli with varying durations were used. The standard durations tested were 0.5 and 3.0 sec. Participants discriminated comparison stimuli which had durations slightly longer and shorter than the standard durations. Difference limens were found by the method of limits and converted to Weber fractions based on the standard durations. Musicians had lower, i.e., better, Weber fractions than nonmusicians in the auditory modality, but there was no significant difference between musicians and nonmusicians in the tactile modality. Auditory discrimination was better than tactile discrimination. Discrimination improved when the standard duration was increased both for musicians and nonmusicians. These results support previous findings of superior auditory processing by musicians. Significant differences between discrimination in the millisecond and second ranges may be due to a deviation from Weber's law and the discontinuity of timing in different duration ranges reported in the literature.     

The perception of concurrent sound objects in harmonic complexes impairs gap detection

Since the introduction of the concept of auditory scene analysis, there has been a paucity of work focusing on the theoretical explanation of how attention is allocated within a complex auditory scene. Here we examined signal detection in situations that promote either the fusion of tonal elements into a single sound object or the segregation of a mistuned element (i.e., harmonic) that "popped out" as a separate individuated auditory object and yielded the perception of concurrent sound objects. On each trial, participants indicated whether the incoming complex sound contained a brief gap or not. The gap (i.e., signal) was always inserted in the middle of one of the tonal elements. Our findings were consistent with an object-based account in which perception of two simultaneous auditory objects interfered with signal detection. This effect was observed for a wide range of gap durations and was greater when the mistuned harmonic was perceived as a separate object. These results suggest that attention may be initially shared among concurrent sound objects thereby reducing listeners' ability to process acoustic details belonging to a particular sound object. These findings provide new theoretical insight for our understanding of auditory attention and auditory scene analysis.     

Citizenship and withdrawal in the workplace: relationship between organizational citizenship behavior, intention to leave current job and intention to leave the organization

This study investigates the relationship between organizational citizenship behavior (OCB) and employee intention to leave the organization and current job using a sample of French employees. A survey was sent to 1,200 alumni of a business school in France. Participation in the study was voluntary. The participants were 355 working adults with French citizenship. This paper provides several interesting findings. While no relationship was found between altruism and intention to leave both the organization and the current job, sportsmanship, civic virtue and helping others emerged as the strongest predictors of intention to leave the organization and intention to leave the current job. Results are discussed.     

Motivated use of information about others: Linking the 2 × 2 achievement goal model to social comparison propensities and processes

The present research used correlational and experimental methods and two well-established social comparison paradigms to integrate and extend prior research from the achievement goal and social comparison literatures. In Study 1, a general disposition to engage in social comparison was positively correlated with each type of goal in the 2 × 2 model of achievement goals, suggesting that the desire to seek out social comparison information is not exclusive to a particular type of achievement goal pursuit. In Study 2, when evaluating the specific direction of social comparison (upward or downward), the pursuit of performance-approach, mastery-approach, and mastery-avoidance goals facilitated upward social comparison, and the pursuit of performance-avoidance goals prompted a shift away from upward comparison towards downward comparison. The present findings provide new insight to the emerging integration of achievement goals and social comparison.     

Risk of crashing with a tram: Perceptions of pedestrians,cyclists, and motorists

IntroductionRoad users not abiding by the rule of tram priority has increased the number of crashes between trams and other road users. This study focuses on the perceptions of pedestrians, cyclists, and motorists regarding the risk of crashes with trams. The first aim was to examine how these road users assess the risk of tram crashes with themselves and with other road users of the same age and type. The second aim was to look into whether and to what extent road users’ comparative judgments about tram risk are realistic in terms of their self-reported behavior.MethodThe study sample included 973 road users (379 pedestrians, 146 cyclists, and 448 motorists). Three versions of a questionnaire were constructed to assess risk perceptions concerning interactions between these road users and trams, self-reported behavior, and knowledge of the tram-priority rules.ResultsThe results showed that all three types of road users perceived the risk of a crash between a tram and themselves to be very low (M = 1.53, SD = 0.88) and with other users to be higher (M = 2.28, SD = 1.06); they therefore expressed comparative optimism. The results also revealed realistic optimism among pedestrians and unrealistic optimism among young motorists.ConclusionThe present study shows that, as a whole, road users have little awareness of crash risks with trams. It may therefore be worthwhile to increase communication about the priority of trams, and to persuade road users not to violate this rule.
