Wild female African elephants (Loxodonta africana) exhibit personality traits of leadership and social integration

Animal personalities have been demonstrated for almost 200 species, with stable dimensions of responses (aggressive to fearful; shy to bold) across contexts and with a heritable basis to these traits. As a long-lived and highly social species, elephants (Loxodonta africana) were expected to demonstrate complex dimensions to individual characteristics or personalities, which would be obvious to human observers and validated by behavioral observations. We used principal-components analysis of ratings on 26 behavioral adjectives applied to one social unit, coded as the EB family, which has been observed for 38 years. Eleven adult females were rated by four observers and found to have individually variable traits on four dimensions described by principal-components analysis. The first component was associated with effective and confident family leadership. Component 2 was age-related, and defined by playfulness, exploration and high levels of activity, suggesting both an experience and an age-related element to its structure. Component 3 represented gentleness and at its other extreme, aggression, and Component 4 was related to constancy (predictability and popularity), with both of these latter components reflecting social integration. Leadership among elephant females represents the successful negotiation among individual interests, and our components were related to a capacity to affect the behavior of others in the absence of aggressive dominance. The family matriarch, Echo, was high on elements associated with leadership. The importance of the matriarch in this family's success suggests that elements of personality may underlie interfamilial variation in long-term survival and reproduction.

Factors Related to Play Therapists' Social Justice Advocacy Attitudes

The authors used a correlational research design to examine how belief in a just world, political ideology, socioeconomic status of family of origin, and percentage of racial minority clients were related to social justice advocacy attitudes among play therapists. A multiple regression was used to analyze the data. Results indicated that belief in a just world and political ideology were related to social justice advocacy. Implications for play therapy training and future directions for research are discussed. Los autores emplearon un diseño correlacional de investigación para examinar cómo la creencia en un mundo justo, la ideología política, el estatus socioeconómico de la familia de origen y el porcentaje de clientes de minorías raciales estaban relacionados con actitudes de apoyo de la justicia social entre consejeros que usan terapia de juego. Se empleó una regresión múltiple para analizar los datos. Los resultados indicaron que la creencia en un mundo justo y la ideología política estaban relacionadas con la defensa de la justicia social. Se discuten las implicaciones para formación en terapia de juego y direcciones futuras para investigación.     

Taking Stock of Behavioral Measures of Adolescent Dating Violence

The past 2 decades have witnessed an increase in dating violence awareness and research. As the field evolves, it is critical to examine the definition and measurement of adolescent dating violence. This article summarizes the behavioral measures of adolescent dating violence used in the field. Based on a review of the literature and federally funded studies, we identified 48 different measures. The most commonly used measures were the Conflict Tactics Scale–2, the Safe Dates Scale, and the Conflict in Adolescent Dating Relationship Inventory, which all examine aspects of psychological, physical, and sexual violence. Researchers also adapted or created their own measures. This article concludes with a discussion of developments for consideration as the field moves forward.     

The Effects of Imagery Training on Swimming Performance: An Applied Investigation

A multiple-baseline design was used to examine the influence of an imagery intervention on the performance of swimmers’ times on a thousand-yard practice set. Performance times for four swimmers were collected over a 15-week period during preseason training. The intervention took place over a 3-week period and was introduced after the fourth week of the study. The results revealed that three out of four participants significantly improved their times on the one thousand-yard practice set after being introduced to the imagery intervention. The results are discussed in terms of the implications of using imagery to improve athlete's performance on continuous tasks.     

The effects of stressors and coping resources on anxiety and peripheral narrowing

Abstract

The purpose of the study was to examine possible mechanisms which might help explain why individuals with high life stress and/or low coping resources are at greater risk for incurring athletic injuries. The effects of life events, daily hassles (DH), and coping resources (CR) on state anxiety and peripheral vision narrowing during a stress condition were examined. Subjects were 74 recreational athletes who completed the Life Events Survey, Daily Hassles Scale (DHS), Vulnerability to Stress Questionnaire (CR), and state portion of the State-Trait Anxiety Inventory. Peripheral vision was measured alone during baseline and while simultaneously performing a Stroop Color-Word Test accompanied by distracting noise during the stress condition. State anxiety was assessed during baseline and the stress condition. Analyses of covariance revealed that high negative life events (NLE) (p = .01) were related to greater peripheral narrowing during the stress condition. High TLE (p = .01) and DH (p = .005) were related to elevated state anxiety during the stress condition. The peripheral vision TLE main effect (p = .03) and the state anxiety interactions of NLE × CR and DHS × CR (ps = .05) approached significance. High CR tended to reduce perceived state anxiety during the stress condition for high NLE and DH subjects compared to similar subjects with low CR. Thus, partial support was offered for the mechanisms proposed in the Andersen and Williams (1988) stress-injury model. The results are discussed in terms of future research needs.     

Taking personality selection bias seriously in animal cognition research: a case study in capuchin monkeys (Sapajus apella)

In most experimental work on animal cognition, researchers attempt to control for multiple interacting variables by training subjects prior to testing, allowing subjects to participate voluntarily, and providing subjects with food rewards. However, do such methods encourage selection bias from subjects’ personalities? In this study, we trained eighteen zoo-housed capuchin monkeys (Sapajus apella) for two experiments, under conditions of positive reinforcement (i.e. food rewards) and free-choice participation. Using a combination of behavioral and rater-based methods, we identified and validated five personality dimensions in these capuchins (Assertiveness, Openness, Neuroticism, Sociability, and Attentiveness). Scores on Openness were positively related to individual differences in monkey task participation, reflecting previous work showing that such individuals are often more active, curious, and willing to engage in testing. We also found a negative relationship between scores on Assertiveness and performance on tasks, which may reflect the trade-offs between speed and accuracy in these animals’ decision-making. Highly Assertive individuals (the most sociable within monkey groups) may also prioritize social interactions over engaging in research. Lastly, monkeys that consistently participated and performed well on both tasks showed significantly higher Openness and lower Assertiveness compared to others, mirroring relationships found between personality, participation, and performance among all participants. Participation and performance during training was clearly biased toward individuals with particular personalities (i.e. high Openness, low Assertiveness). Results are discussed in light of the need for careful interpretation of comparative data on animal cognition and the need for researchers to take personality selection bias more seriously.     

Effects of Visual Information and Task Constraints on Intersegmental Coordination in Playground Swinging

The authors investigated how and to what extent visual information and associated task constraints are negotiated in the coordinative structure of playground swinging. Participants (N = 20) were invited to pump a swing from rest to a prescribed maximal amplitude under 4 conditions: normal vision, no vision, and 2 visual conditions involving explicit phasing constraints. In the latter conditions, participants were presented with a flow pattern consisting of a periodically expanding and contracting optical structure. They were instructed to phase the swing motion so that the forward turning point coincided with either the maximal size (enhanced optical flow) or the minimal size (reduced optical flow) of the presented flow pattern. Removal of visual information clearly influenced the swinging behavior, in that intersegmental coordination became more stereotyped, reflecting a general stiffening of the swinger. The conditions involving explicit phasing requirements also affected the coordination, but in an opposite way: The coordination became less stereotyped. The two phasing instructions had differential effects: The intersegmental coordination deviated more from normal swinging (i.e., without phasing constraints) when optical flow was enhanced than when it was reduced. Collectively, those findings show that visual information plays a formative role in the coordinative structure of swinging, in that variations of visual information and task constraints were accompanied by subtle yet noticeable changes in intersegmental coordination.     

The effects of creative,expressive, and reflective writing on career learning: An explorative study

This study investigates whether creative, expressive, and reflective writing contributes to the formation of a work-life narrative that offers both meaning and direction among students in higher education. The content of writing done by students who participated in a two-day writing course at the start (or in preparation) of their work placements and of a control group who did not take part in the course were compared. Writing samples were analysed using the Linguistic Index Word Count program (Pennebaker, Booth, & Francis, 2007) and an instrument based on Dialogical Self Theory (Hermans & Hermans-Konopka, 2010). Results show writing promotes the development of career narratives.     

Impact of chronic illness: Differing perspectives of younger and older women

Abstract

The purpose of this study was to examine the life experiences of six women with chronic illness who represent three differing life stages. The participants included two women who were in young adulthood, two who were between the ages of 40 and 60, and two women in their late 70s. The women were all diagnosed with multiple sclerosis, systemic lupus erythematosus, rheumatoid arthritis, osteoporosis, or a combination of these disorders. They were interviewed concerning the impact illness has had on their lives, the manner in which chronic illness has altered their self-perceptions, and the ways in which they have come to make meaning from the event. While the women had achieved varying levels of acceptance of their illness, it appeared that the ability to cope was dependent on numerous factors across several life circumstances. Distinctions were made regarding ability to either adjust to the illness or use the experience as a catalyst for personal growth.     

Multiple trajectories of physical aggression among adolescent boys and girls

Latent growth mixture modeling was used to identify discrete patterns of physical aggression from Grades 7 to 11 among a sample of 1,877 youth. Four trajectory classes adequately explained the development of physical aggression in both boys and girls: Low/No Aggression; Persistent High Aggression; Desisting Aggression, characterized by decreasing risk throughout adolescence; and Adolescent Aggression, characterized by low early risk that increases until Grade 9, levels out, and then declines in late adolescence. Girls were less likely than boys were to be in any trajectory besides the Low/No Aggression trajectory. Parental supervision, deviant peer association, academic orientation, impulsivity, and emotional distress at Grade 7 were all strongly associated with trajectory class membership. These associations did not differ by gender. These findings strongly suggest that the processes involved in the development of physical aggression in adolescence operate similarly in boys and girls.
