Various relationships between predatory dominance and aggressive behavior in Pairs of cats

The experiments were performed on adult male cats selected initially as good mousekillers. Cats were tested in pairs and each pair was introduced separately to the experimental compartment. The attitude toward the partner before and during the predatory competition test as well as superiority in catching and killing the mice, considered as an index of dominance, were registered. In the course of experiment five types of relations between the predatory dominance and aggressive behavior were observed. The concept of dominance as an outcome of several factors was discussed. It was concluded that predatory dominance is not based exclusively on aggressive mechanisms, as it may be formed and sustained without overt aggression.

Defensive reactions of “wild-type” and “Domesticated” wild rats to approach and contact by a threat stimulus

Selective breeding of wild rats over many generations on the basis of low or high defensive threat and attack to human approach and contact has produced highly polarized “domesticated” and “wild-type” animals. Because the selection procedure selectively involves these two defense patterns, and these clearly differ in the two groups, it is of interest to determine if other, nonselected, defensive behaviors to threat stimuli also change. “Domesticated” and “wild-type” rats of the thirty-fifth generation were run in a fear defense test battery (F/DTB) to systematically evaluate defensive behaviors to a variety of present threat stimuli. “Domesticated” rats showed reduced avoidance and slower flight speed to an approaching experimenter, reduced jump/startle response to handelap and dorsal contact, less vocalization and boxing to vibrissae stimulation or to an anesthetized conspecific, and reduced defensiveness to an attempted pickup by the experimenter. These results indicate that selective bi-directional breeding for defensive threat and attack to human approach and contact produces group differences in a variety of defensive behaviors, and in defensiveness to stimuli other than those on which the selection was based. © 1994 Wiley-Liss, Inc.     

Integrated learning communities as a peer support initiative for first year university students

Peer Mentoring schemes tend to be developed as retention strategies, however, they can also serve other purposes (psychosocial or career-related). However, evidence of the effectiveness of these presents mixed results and less is known about the horizontal peer support schemes which may help students capitalize on existing peer relationships. We developed an integrated learning communities (ILC) peer support scheme, building on the theoretical principles of social identity theory, which we embedded within our existing teaching framework and designed functional activities. Collective activities were undertaken to promote the processes of social identity with the intention that these may foster social and academic integration experiences. This intervention was undertaken with an entire cohort of first year undergraduate psychology students. We conducted semi-structured interviews with a self-selected sample of these students (N = 17). Thematic analysis revealed two main themes, each with two sub-themes. These were: “Divergent Experiences” with the sub-themes of “dependent on people” and “types of support”, and “Good idea in principle” with the sub-themes of “Theory ≠ Practice” and “Dependent on student engagement”. Although identifying with a peer group was not transparent in the interviews, the existence of a peer support scheme was perceived positively by students which might explain the success of the newly developed student-led Psychology Society. Indeed, this Psychology Society can provide a lasting framework for further amplification of the student voice. We conclude that our embedded ILC was both feasible and potentially valuable, but it is crucial for the peer support approach to have transactional significance.     

What Spirituality Means for Patients and Families in Health Care

This research focuses on the spiritual care experiences of patients and families at a hospital in Australia. Twenty-four patients and 10 family members were interviewed. Results indicate the importance of relatedness: being treated as a person, reminded of your capabilities and conversations about what matters. Maintaining contact with friends and family, sustaining religious and spiritual practices, music therapy and pet therapy were also significant and contact with the natural world and shared activities. The results indicate the importance of spirituality offered through pastoral care, and that all those involved in health care can contribute to the spiritually nurturing environment that reinforces healing.

Decision-makers use social information to update their preferences but choose for others as they do for themselves

People's risky decisions are susceptible to the social context in which they take place. Across three experiments using different paradigms, we investigated the influence of three social factors upon participants' decisions: the recipient of the decision-making outcome (self, other, or joint), the nature of the relationship with the other agent (friend, stranger, or teammate), and the type of information that participants received about others' preferences: none at all, general information about how previous participants had decided, or information about a specific partner's preference. We found that participants' decisions about risk did not differ according to whether the outcome at stake was their own, another agent's, or a joint outcome, nor according to the type of information available. Participants did, however, adjust their preferences for risky options in light of social information.

消极身体意象对青少年的负面影响

消极身体意象是青少年健康成长所面临的重要问题之一。了解消极身体意象对青少年的危害以及其形成的影响因素, 对于青少年群体身心健康发展具有重要意义。消极身体意象对青少年的负面影响主要包括自我概念、情绪体验、体重控制策略、饮食失调和社会生活五个方面; 并且青少年消极身体意象形成的影响因素主要有生物因素(BMI)、社会文化因素(父母、同伴和大众媒体)和心理因素(人格因素、认知方式)。未来可从以下几个方面进一步深入研究：(1) 基于生物-心理-社会模型的视角完善青少年身体意象发展的理论模型; (2) 考察社交媒体等新兴因素的作用; (3) 阐明青少年在加工身体相关信息时的认知特点; (4) 推进中国青少年消极身体意象本土化研究。
