Effect of chronic ethanol administration on intermale aggression in rats

An experiment was performed to study the effect of chronic ethanol administration on intermale aggression in rats using a 24-hour resident-intruder test. During the resident-intruder test residents displayed virtually all of the agonistic behaviors, and intruders displayed virtually all of the defensive behaviors. Intruders treated with ethanol displayed more defensive behavior and elicited more agonistic behavior than control intruders. Twenty minutes into the resident-intruder test intruders showed the greatest increase in corticosterone (338% vs. 129%), while residents showed the greatest increase in testosterone (103% vs. 18%). On the 2nd day of the resident-intruder test intruders lost more weight than residents (21.5 g vs. 10.2 g). Plasma corticosterone levels remained elevated for the intruders, and in particular for those intruders displaying defensive behaviors regardless of the resident's behavior. Plasma testosterone levels remained elevated for those residents that were paired with intruders that displayed defensive behaviors regardless of the resident's behavior. The frequency and severity of biting attacks by ethanol residents was significantly greater than that of control residents. In addition, the locus of biting attack shifted from the upper back of intruders paired with control residents to the flanks, tail, lower feet, and ventral surface on intruders paired with ethanol residents.     

Hungry people prefer larger bodies and objects: The importance of testing boundary effects

Several lab-based studies have indicated that when people are hungry, they judge larger women's bodies as more attractive, compared to when they are satiated. These satiety-dependent judgements are assumed to provide explanatory power when it comes to the noted cross-cultural differences in attitudes towards women's adiposity, whereby people who live in regions that are under greater nutritional stress tend to have more favourable attitudes towards bigger bodies. However, it is premature to assume that women's bodies are the proper or actual domain of the satiety-dependent judgement shifts found within research study testing contexts until stimuli other than female bodies have also been tested: The research programme falls into the trap of confirmation bias unless we also seek out disconfirmatory evidence and test the boundaries of the effects of hunger. Accordingly, we collected attractiveness judgements of female and male bodies manipulated to vary in size by varying level of adiposity, and objects manipulated to vary in size, from 186 participants who also reported their current hunger level. We found that larger sizes of stimuli in general, and women's bodies in particular, especially when judged by women, were judged as more attractive by the hungrier participants. We discuss these patterns in the context of the Insurance Hypothesis, the Environmental Security Hypothesis, and the impact of hunger on acquisition.     

Possession and Applicability of Signature Character Strengths: What Is Essential for Well-Being,Work Engagement,and Burnout?

Signature character strengths can foster health-related outcomes in work and private life, thus being particularly important for endangered occupational groups like physicians. However, situational circumstances need to allow character strengths demonstration (applicability) first to enable their application. Therefore, this study addresses the role of (1) applicability of signature character strengths in work and private life beyond their possession and (2) relationships with well-being, work engagement, and burnout dimensions (emotional exhaustion, depersonalization, and reduced personal accomplishment). Hospital physicians (N = 274) completed an online survey examining their signature character strengths and applicability, well-being, work engagement, and burnout dimensions. The top-five individual signature character strengths were fairness, honesty, judgment, kindness, and love. Hierarchical multiple linear regressions revealed that the possession as well as the applicability of signature character strengths was important in work and private life, but to different degrees. Possessing fairness, honesty, or kindness indicated significant positive relations with subjective well-being, whereas judgment and kindness seemed to negatively interact with reduced personal accomplishment. Hospital physicians’ applicability of fairness, honesty, judgment, and love was particularly essential for their psychological well-being and work engagement, whereas the applicability of fairness (reduced personal accomplishment) and judgment (emotional exhaustion, depersonalization) at work interacted negatively with the respective outcomes. Therefore, creating awareness for individual signature character strengths as well as providing applicability in hospitals and private life could be a promising approach to improve physicians’ well-being and consequently patient care as well as the performance of the health-care system in general.

     

Psychometric Characteristics of the German Values in Action Inventory of Strengths 120-Item Short Form

The original Values in Action Inventory of Strengths (VIA-IS) is an international 240 item validated self-report questionnaire measuring character strengths. A validated and reliable English 120-item short form (VIA-120) is available. However, there is limited information about the psychometric properties of the German VIA-120. This article addresses this gap and reports the reliability, validity and comparability of the German VIA-120 with the German VIA-240 version. Two independent samples were recruited: a general population sample (N = 1073, Sample 1) and a sample consisting of medical students and physicians (N = 685, Sample 2). Internal consistency of the VIA-120-scales ranged from α = .58 (modesty) to α = .87 (spirituality) in Sample 1 and α = .63 (honesty) to α = .90 (spirituality) in Sample 2. Intercorrelations between the scales of the 120-item version and the original 240-Items version (Sample 1) ranged from r = .52 (hope) to r = .89 (prudence). Criterion validity with the Satisfaction with Life Scale (SWLS) and the Brief Inventory of Thriving (BIT) was demonstrated. The comparison of the factor structure between the original and the short form showed a good convergence (Tucker’s Phi .93–.99 Sample 1, .95–.98 Sample 2). Overall, the German VIA-120 was reliable, showed good convergence with the German VIA-240 and thus presents a similar level of validity for the assessment of character strengths. This study provides the first indication that the VIA 120 short form is comparable regarding the validity and reliability of the original VIA 240-item version indicating its potential to be used in large scale research studies.

     

Infant clinical assessment procedure: Its applications for diagnosis and treatment in the second and third year

This article reports on some clinical applications in the 9 to 30 month age range of a new structured paradigm. The Infant Clinical Assessment Procedure (ICAP) is not a test, but an assessment technique. It is particularly aimed at the evaluation and ongoing monitoring of problems in the emotional development of infants. Its eight episodes represent a wide array of effective, social, and cognitive stimuli. The primary focus of these episodes is on the infant, with the exception of the mother-infant task that specifically gauges the mother-infant ralationship. It is suggested through case vignettes that the ICAP may be useful for the documentation of the efficacy of treatment.     

The mistaken mirror: On Wundt'S and Titchener'S psychologies

Most psychologists believe that Structuralism, the psychology of E. B. Titchener, was a faithful copy of Wilhelm Wundt's original psychology. This belief is fostered by textbooks for history and systems and introductory psychology courses. The present paper argues that this belief is false. Titchener rejected many of Wundt's goals and concepts, and should be viewed as a traditional British associationist and positivist rather than as a follower of Wundt. Similarities of Wundt's system and Titchener's system to current psychological thinking are noted.     

Aggressive behavior in the free-ranging rhesus monkeys of kathmandu,nepal

We present a composite sample of the aggressive behavior of free-ranging rhesus monkeys (Macaca mulatta), recorded at two temples in Kathmandu, Nepal. We analyze the total number and the rate per monkey of threats, chases, attacks, fights, and aggressive acts directed at other species (principally humans), in order to elucidate social dynamics of the troop as a whole. Our 1,506 hours of observation were divided among the four seasons; between a.m. and p.m.; and among a temple yard, two parklands, and a forested garden. We found seasonal patterns to be the most important correlates of aggressive behavior. Habitat was a modulating influence, and time of day was the least important factor. Rates of aggression were generally higher per male monkey than per female. In terms of total aggression recorded, however, females instigated significantly more than males, both in encounters between monkeys and in aggression against other species. This finding is consistent with the females' greater numbers in the troop and with their lifelong membership in the troop. Analysis of behavior by social groups, rather than by individual rates, points up the iomportance of adult females and their social stability in troop behavior.     

Animal Abuse among High-Risk Youth: A Test of Agnew’s Theory

ABSTRACT

Concern over animal abuse among policy-makers, law enforcement officials, and the general public remains high. Although research has marked animal abuse as an indicator of a variety of deviant outcomes, fewer projects have examined the correlates of cruelty towards animals. In this study, we apply Agnew’s theory of animal abuse to explore how a wide-range of characteristics relate to deviance towards animals. In support of Agnew’s theory, results reveal that a combination of individual traits and behaviors, socialization experiences, and mechanisms of social control significantly relate to animal abuse. However, measures of strain do not appear to relate to animal abuse, providing only partial support to the theory.
