Ethological analysis of the male rat's socioagonistic behavior in a resident-intruder paradigm

The object of the present study was to assess the rat's socioagonistic behavior by means of ethological procedures. Two groups of male Wistar rats were used: 33 residents and 66 intruders. To allow reliable characterization of social and agonistic patterns, social interactions were increased by the isolation of residents and, on the other hand, both offense in residents and defense in intruders were increased by differences in weight, agonistic experience, and habituation to the enclosure. Encounters were videotaped, and the animals' behavior was analyzed by a 27-pattern ethogram and a software package made up to this end. Several patterns parameters were quantified, and two ethological mathematical models were employed: sequential analysis of preferential directions and cluster analysis based on similarities between patterns. Following mean latencies of the most frequent elements, the first four pattern sequences appeared to be the same in both groups of animals. From the fifth pattern on, residents displayed mainly dominance and threat, whereas intruders showed defensive and submissive patterns. Attack was also displayed by residents, but less frequently than dominance and threat. The alpha status was established by two sorts of domination, either through dominance and threat or by attack. The mean frequency of the intraindividual transition of patterns was higher in residents than in intruders. Pathway graphs, derived from sequential analysis, showed some common dyads, triads, or quadrads of patterns, but they basically defined different behavior structures in residents and intruders. Dendrograms, obtained by cluster analysis, allowed classification of patterns into behavior categories. The categories in residents were exploration, dominance, threat, and attack, and they encompassed 18 elements; in intruders the categories were exploration, dominance, and defense, and they consisted of nine patterns. A submissive category composed of three patterns could be also deduced considering similarity results. To summarize, six behavior categories were obtained: one “socioindividual” (exploration) and five “agonistic” (dominance, threat, attack, submission, and defense). In conclusion, the present study shows how ethological procedures may help to elucidate the rat's socioagonistic behavior and to classify the observed patterns into behavior categories.     

Sequential learning in individuals with agrammatic aphasia: evidence from artificial grammar learning

We examined sequential learning in individuals with agrammatic aphasia (n = 12) and healthy age-matched participants (n = 12) using an artificial grammar. Artificial grammar acquisition, 24-hour retention, and the potential benefits of additional training were examined by administering an artificial grammar judgment test (1) immediately following auditory exposure-based training, (2) one day after training, and (3) after a second training session on the second day. An untrained control group (n = 12 healthy age-matched participants) completed the tests on the same time schedule. The trained healthy and aphasic groups showed greater sensitivity to the detection of grammatical items than the control group. No significant correlations between sequential learning and language abilities were observed among the aphasic participants. The results suggest that individuals with agrammatic aphasia show sequential learning, but the underlying processes involved in this learning may be different than for healthy adults.     

‘Everybody's entitled to their own opinion’: ideological dilemmas of liberal individualism and active citizenship

Conversational interview accounts were used to explore everyday understandings of political participation on the part of young white adults in England. Analysis focussed on dilemmatic tensions within respondents' accounts between values of active citizenship and norms of liberal individualism. Respondents could represent community membership as engendering rights to political participation, whilst also arguing that identification with local or national community militates against the formulation of genuine personal attitudes and rational political judgement. Respondents could represent political participation as a civic responsibility, whilst also casting political campaigning as an illegitimate attempt to impose personal opinions on to others. Formal citizenship education did not appear to promote norms of political engagement but rather lent substance to the argument that political decision-making should be based on the rational application of technical knowledge rather than on public opinion or moral principle. In conclusion we question whether everyday understandings of responsible citizenship necessarily entail injunctions to political action. Copyright © 2007 John Wiley & Sons, Ltd.

ESOTERIC CONFUCIANISM,MORAL DILEMMAS,AND FILIAL PIETY

Two controversial cases in Confucian literature present the demands of filial piety as conflicting with those of impartial justice. Let us call them the Case of Concealment (Analects 18.13) and the Case of Evasion (Mencius 7A53). A dogmatic reading of the texts indicates that both Confucius and Mencius give more weight to filial piety than to justice. This essay, however, provides an alternative reading of the cases: the liberal reading. I argue that the Confucian teachers used the cases as moral dilemmas that force Confucian students to learn how to use a cluster of Confucian virtues, including practical wisdom, discretion, and straight determination, under difficult circumstances. The liberal reading views these moral dilemmas as rhetorical tools; they guide Confucian students in meditative exercises and ultimately transform students’ mode of seeing and being.     

Are choices based on conditional or conjunctive probabilities in a sequential risk-taking task?

In this study, we examined participants' choice behavior in a sequential risk-taking task. We were especially interested in the extent to which participants focus on the immediate next choice or consider the entire choice sequence. To do so, we inspected whether decisions were either based on conditional probabilities (e.g., being successful on the immediate next trial) or on conjunctive probabilities (of being successful several times in a row). The results of five experiments with a simplified nine-card Columbia Card Task and a CPT-model analysis show that participants' choice behavior can be described best by a mixture of the two probability types. Specifically, for their first choice, the participants relied on conditional probabilities, whereas subsequent choices were based on conjunctive probabilities. This strategy occurred across different start conditions in which more or less cards were already presented face up. Consequently, the proportion of risky choices was substantially higher when participants started from a state with some cards facing up, compared with when they arrived at that state starting from the very beginning. The results, alternative accounts, and implications are discussed.     

The Space–Time Congruency Effect: A Meta‐Analysis

Several reaction time (RT) studies report faster responses when responses to temporal information are arranged in a spatially congruent manner than when this arrangement is incongruent. The resulting space–time congruency effect is commonly attributed to a culturally salient localization of temporal information along a mental timeline (e.g., a mental timeline that runs from left to right). The present study aims to provide a compilation of the published RT studies on this time–space association in order to estimate the size of its effect and the extent of potential publication bias in this field of research. In this meta‐analysis, three types of task are distinguished due to hitherto existing empirical findings. These findings suggest that the extent to which time is made relevant to the experimental task has a systematic impact on whether or not the mental timeline is activated. The results of this meta‐analysis corroborate these considerations: First, experiments that make time a task‐relevant dimension have a mean effect size of d = 0.46. Second, in experiments in which time is task irrelevant, the effect size does not significantly deviate from zero. Third, temporal priming studies have a surprisingly high mean effect size of d = 0.47, which, however, should be adjusted to d = 0.36 due to publication bias.     

Social dilemmas as strong versus weak situations: Social value orientations and tacit coordination under resource size uncertainty

This study investigates how environmental uncertainty in resource dilemmas influences the decisions of participants differing in social value orientations. We argue that under resource size certainty people anchor their decisions on tacit coordination rules such as the equal division rule, whereas under resource size uncertainty people rely more on their own social value orientations to determine their choice behavior. The results corroborate our line of reasoning. When the size of the resource was certain, proselfs as well as prosocials anchored their decisions on the equal division rule. Under resource size uncertainty, the equal division rule appeared to lose its coordinating potential, inducing proselfs to harvest more than prosocials.     

‘How can we help when she won't tell us what's wrong?’ Professionals working with South Asian women who have experienced sexual abuse

In this paper, we explore some of the issues facing professionals in the UK currently involved in providing services for South Asian women who have experienced sexual abuse. The study describes part of a wider Economic and Social Research Council funded project, based upon interviews and focus groups with both professionals and women survivors of sexual abuse. Drawing on semi‐structured interviews and two focus groups with 37 professionals including psychological therapists, refuge and project workers, from a range of organisations, our aim in this paper is to provide a discursive analysis of some of the key dilemmas faced by professionals working with sexual abuse in South Asian communities by exploring two central interpretive repertoires: ‘culture not self’ and ‘symptom talk as solution’. The analysis indicates that professionals face a series of dilemmas when working with South Asian women survivors. They highlight the tension between individualised models of personhood in many psychological therapies and the challenge to these by South Asian communities who hold a more relational view of the person. One of the strategies used by professionals to work with the tensions between ‘culture’ and the ‘reality’ of the survivor's pain was the translation of women's distress into symptoms of mental disorder. However, the consequences of this intervention raised some serious issues, including further pathologisation and stigma. The implications of these findings will be discussed in terms of how to understand the experiences of South Asian women from a more socially grounded perspective and to explore the issues they face in accessing and receiving appropriate services to deal with the aftermath of sexually abusive experiences.

Dilemmas of Practice: Challenges to Program Quality Encountered by Youth Program Leaders

To create and sustain high quality youth development programs it is important to understand the challenging situations and dilemmas that emerge in program leaders’ daily work with youth. In this research the experiences of leaders in 12 programs were followed over a 2–9 month period, which led to the identification of 250 dilemma situations. Qualitative analyses identified 5 categories and 12 subcategories of dilemmas that reflected distinct types of considerations (e.g., youth’s personalities, relationships with the community). The analyses also found that the experienced leaders in the study typically responded to these dilemmas in ways that were youth-centered and that balanced multiple considerations. It is argued that researchers need to go beyond identifying features of high quality programs, and more fully examine how effective leaders create and sustain high quality in response to the challenging situations of practice.
