Domestic dogs’ (Canis familiaris) choices in reference to information provided by human and artificial hands

Even young humans show sensitivity to the accuracy and reliability of informants’ reports. Children are selective in soliciting information and in accepting claims. Recent research has also investigated domestic dogs’ (Canis familiaris) sensitivity to agreement among human informants. Such research utilizing a common human pointing gesture to which dogs are sensitive in a food retrieval paradigm suggests that dogs might choose among informants according to the number of points exhibited, rather than the number of individuals indicating a particular location. Here, we further investigated dogs’ use of information from human informants using a stationary pointing gesture, as well as the conditions under which dogs would utilize a stationary point. First, we explored whether the number of points or the number of individuals more strongly influenced dogs’ choices. To this end, dogs encountered a choice situation in which the number of points exhibited toward a particular location and the number of individuals exhibiting those points conflicted. Results indicated that dogs chose in accordance with the number of points exhibited toward a particular location. In a second experiment, we explored the possibility that previously learned associations drove dogs’ responses to the stationary pointing gesture. In this experiment, dogs encountered a choice situation in which artificial hands exhibited a stationary pointing gesture toward or away from choice locations in the absence of humans. Dogs chose the location to which the artificial hand pointed. These results are consistent with the notion that dogs may respond to a human pointing gesture due to their past-learning history.     

Happy but unhealthy: The relationship between social ties and health in an emerging network

Social connections are essential to health and well‐being. However, when pursing social acceptance, people may sometimes engage in behavior that is detrimental to their health. Using a multi‐time‐point design, we examined whether the structure of an emerging network of students in an academic summer school program correlated with their physical health and mental well‐being. Participants who were more central in the network typically experienced greater symptoms of illness (e.g., cold/flu symptoms), engaged in riskier health behaviors (e.g., binge drinking), and had higher physiological reactivity to a stressor. At the same time, they were happier, felt more efficacious, and perceived less stress in response to a strenuous math task. These outcomes suggest that social ties in an emerging network are associated with better mental well‐being, but also with poorer physical health and health behaviors.

The effects of photographs and event plausibility in creating false beliefs

Recent studies have shown that using photographs as memory retrieval aids can significantly increase the likelihood of false memories. The current study further investigated this effect by examining the interactive effects of photographs and event plausibility in developing false beliefs. At Time 1 and two weeks later at Time 2, participants rated 20 events on the Life Events Inventory (LEI) as to whether each occurred to them in childhood. One week after Time 1, participants were told that two target events were plausible and two were implausible. They then used event-related photographs to visualize one plausible and one implausible event. Occurrence ratings significantly increased from Time 1 to Time 2 for plausible events in the photo condition. These results suggest that the use of photographs as a memory enhancing technique is unlikely to cause false memories for events that are not perceived personally plausible.     

Developing an indicator of family function and a practicable outcome measure for systemic family and couple therapy: the SCORE

There is a need for a measure of outcome in systemic family and couples therapy (SFCT) that reflects current theory and practice. To meet the needs of SFCT practice the measure needs to use self‐report by family members, take a short time to complete and be easy to understand. The development of such a measure, called the SCORE, is reported in this article. Substantial piloting, consultation and review in terms of clinical judgement led to the construction of the SCORE 40 which has forty items about how the family functions, rated by family members over 11 years of age on a Likert scale, in addition to independent ratings of the family and its difficulties. The SCORE 40 is shown to be a viable instrument but is too substantial for everyday clinical use. In a research project to reduce and refine the measure and determine its psychometric properties the SCORE 40 was administered to 510 members of 228 families at the start of their first appointment for family therapy at clinics throughout the UK. The scale has good psychometric properties and could operate with either three or four dimensions. The analyses of these data, combined with data from a convenience sample of 126 non‐clinical families, allowed a reduction to fifteen items while retaining most of the information provided by the SCORE 40. This version is offered with three dimensions of: (1) Strengths and adaptability; (2) Overwhelmed by difficulties; and (3) Disrupted communication. It is hoped that the ready availability of the SCORE 15 will encourage routine evaluation of outcomes in clinics as well as the SCORE being used flexibly for both therapy and research.     

Search strategies in decision making: the success of “success”

Examination of search strategies has tended to focus on choices determined by decision makers' personal preferences among relevant cues, and not on learning cue‐criterion relationships. We present an empirical and rational analysis of cue search for environments with objective criteria. In such environments, cues can be evaluated on the basis of three properties: validity (the probability that a cue identifies the correct choice if cue values differ between alternatives); discrimination rate (the proportion of occasions on which a cue has differing values); and success (the expected proportion of correct choices when only that cue can be used). Our experiments show that though there is a high degree of individual variability, success is a key determinant of search. Furthermore, a rational analysis demonstrates why success‐directed search is the most adaptive strategy in many circumstances. Copyright © 2004 John Wiley & Sons, Ltd.     

What Does the Development of Fresh Expressions of Church in the UK Tell Us about Mission Today?

This article explores the significance of the Fresh Expressions movement in the UK since the ground‐breaking Mission‐Shaped Church report was published by the Church of England in 2004. After reviewing the background to this report, the article explores some of the report's central themes and examines some of the more recent research on the movement's impact in the UK. It then highlights six ways in which fresh expressions continue to be significant as a missionary response in a post‐Christian context. These include the movement's theological underpinnings, its reassessment of key questions in ecclesiology, its commitment to local and contextual mission, and the emergence of a predominantly lay leadership. In recognizing that the movement is still in a state of evolution, the article concludes by suggesting some areas of continuing debate and challenge for the future.     

Academic Guidance in Medical Student Research: How Well Do Supervisors and Students Understand the Ethics of Human Research?

Research is increasingly recognised as a key component of medical curricula, offering a range of benefits including development of skills in evidence-based medicine. The literature indicates that experienced academic supervision or mentoring is important in any research activity and positively influences research output. The aim of this project was to investigate the human research ethics experiences and knowledge of three groups: medical students, and university academic staff and clinicians eligible to supervise medical student research projects; at two Australian universities. Training in research ethics was low amongst academic staff and clinicians eligible to supervise medical student research. Only two-thirds of academic staff (67.9 %) and students (65.7 %) and less than half of clinicians surveyed (47.1 %; p?=?0.014) indicated that specific patient consent was required for a doctor to include patient medical records within a research publication. There was limited awareness of requirements for participant information and consent forms amongst all groups. In the case of clinical trials, fewer clinicians (88.4 %) and students (83.3 %) than academics (100 %) indicated there was a requirement to obtain consent (p?=?0.009). Awareness of the ethics committee focus on respect was low across all groups. This project has identified significant gaps in human research ethics understanding among medical students, and university academic staff and clinicians. The incorporation of research within medical curricula provides the impetus for medical schools and their institutions to ensure that academic staff and clinicians who are eligible and qualified to supervise students’ research projects are appropriately trained in human research ethics.
