Teaching Ethical Decision Making: Designing a Personal Value Portrait to Ignite Creativity and Promote Personal Engagement in Case Method Analysis

The case method approach to introducing ethical issues is a traditional tool for applying critical thinking skills to a specific dilemma (Beauchamp &; Childress, 2001 Beauchamp, T. L. and Childress, J. F. 2001. Principles of biomedical ethics, 5th, New York: Oxford University Press.  [Google Scholar]). It allows for personal reflection and clarification of an individual's conceptual framework for deciding what is and is not ethical behavior. However, it also affords the student distance from the story line and may, through providing a retrospective critique, prevent sufficient challenge to the student to articulate and defend personal value assessments in addressing the ethical dynamics reflected in the case. Providing teaching exercises that encourage the creation of language to form that conceptual framework and a comfort in using that language allows the student to not only identify ethical issues but also recognize and more effectively communicate the struggles with molding a personal values portrait to apply to such cases.     

Grounding spatial language in the motor system: Reciprocal interactions between spatial semantics and orienting

Shifts of attention that are directed by spatial words are thought to be mediated by a spatial frame of reference. Previous studies have documented a selection cost when visual attention is directed along the left/right axis relative to the above/below axis due to the greater ambiguity of the horizontal endpoints. The present study investigated whether the horizontal endpoints may be more fully disambiguated when “left/right” cues are first enacted by nondivisible, more discrete, modes of orienting such as directional motor responses. This issue was investigated using a repetition priming paradigm in which the effects of prior enactments were measured on the subsequent conceptual control of visual attention. The results of four experiments showed that grounding spatial language in the motor system can enhance the focus of visual attention by disambiguating the endpoints of the horizontal axis. In so doing, the present study extends previous research demonstrating that spatial concepts can influence the spatial distribution of attention by demonstrating that different modes of orienting can also influence the semantics of space. Implications for the premotor theory of attention and grounded theories of cognition are also discussed.     

Associations amongst disease severity,religious coping and depression in a cohort of Jamaicans with sickle-cell disease

The purpose of this study was to investigate the relationship between disease severity (sickle-cell type and hospital, emergency room and clinic emergency visits (CEU)), religious coping (positive and negative) and depression. This was accomplished through secondary analysis of a data set based on a Comprehensive Sickle Cell Standardized Questionnaire compiled by a multidisciplinary team of professionals from Duke University Medical Centre, and administered to persons with sickle-cell disease being treated at the Sickle Cell Unit on the University of the West Indies Campus between November 2008 and January 2009. Disease severity was not a good predictor of depression within the population. On the other hand, depression was found to correlate with positive and negative religious coping, such that increases in the former were associated with decreases in depression scores; while the reverse was noted for the latter (negative religious coping). The results shed light on issues that could possibly impact the treatment plan for such individuals.     

Tests of inferential reasoning by exclusion in Clark’s nutcrackers (Nucifraga columbiana)

We examined inferential reasoning by exclusion in the Clark’s nutcracker (Nucifraga columbiana) using two-way object-choice procedures. While other social scatter-hoarding corvids appear capable of engaging in inferential reasoning, it remains unclear if the relatively less social nutcracker is able to do so. In an initial experiment, food was hidden in one of two opaque containers. All of the birds immediately selected the baited container when shown only the empty container during testing. We subsequently examined the nutcrackers in two follow-up experiments using a task that may have been less likely to be solved by associative processes. The birds were trained that two distinctive objects were always found hidden in opaque containers that were always positioned at the same two locations. During testing, one of the two objects was found in a transparent “trash bin” and was unavailable. The birds were required to infer that if one of the objects was in the “trash,” then the other object should still be available in its hidden location. Five out of six birds were unable to make this inference, suggesting that associative mechanisms likely accounted for our earlier results. However, one bird consistently chose the object that was not seen in the “trash,” demonstrating that nutcrackers may have the ability to use inferential reasoning by exclusion to solve inference tasks. The role of scatter hoarding and social organization is discussed as factors in the ability of corvid birds to reason.     

Shedding light on photosensitive behaviour in brown planaria (Dugesia Tigrina)

The planarian flatworm is one of the simplest animals to develop two eyecups that enable them to detect the presence and direction of light, which they typically avoid. In this study we assessed responses of planaria to different intensities of light. We found that they exhibited a graded, sigmoidal, photonegative response to light intensity. A two-octave increase in luminance (on the upward slope of the sigmoid) corresponded to a 9% increase in the speed planaria travelled to avoid light.     

Semantic and affective salience: the role of meaning and preference in attentional capture and disengagement

Emotion appears to have a substantial impact on a wide variety of attentional functions. However, stimuli that elicit affective responses also tend to be meaningful. Here we attempted to disentangle the effects of meaning from the effects of affect on attentional capture by irrelevant distractors. Experiment 1 used a previously unfamiliar distractor stimulus, and manipulated the amount of knowledge provided to observers about the distractor. The results suggested that increases in meaning can reduce attentional capture. Experiments 2 and 3 used both familiar and unfamiliar symbols (baseball logos and flags, respectively) as distractors. Critically, of the two familiar symbols, one was rated as affective-positive and the other was rated as affective-negative. As in Experiment 1, the results showed that unfamiliar distractors can capture attention. In addition, the results also suggested that the two affective distractors captured attention (so long as they were sufficiently intense). This finding suggests that while increased knowledge can reduce capture, affect can restore an item's ability to capture attention. Finally, the results of Experiment 4 showed that observers were slower to disengage from a negative item than from a positive item. This evidence emphasizes the differential roles of semantic knowledge versus affect on attentional capture.     

Do People Comprehend Legal Language in Wills?

This study assessed the ability of laypeople to understand a document that most have read and signed: a last will and testament. We focused on concepts that are frequently included in wills, examined whether understanding can be enhanced by psycholinguistic revisions, and assessed comprehension as a function of age. Participants ages 32 to 89 years read will‐related concepts in (i) their traditional format, (ii) a version revised to increase readability, or (iii) a version in which, in addition to those changes, we explained archaic and legal terms. Results showed that increasing the readability and explaining terms enhanced participants' abilities to apply will‐related concepts to novel fact patterns and to explain their reasoning. We found no age‐related effects on comprehension, consistent with well‐documented findings that processing at the situation level of text comprehension is preserved in older adults. We discuss the implications of these findings and suggest ideas for further research. Copyright © 2012 John Wiley & Sons, Ltd.     

‘I'm not a war monger but…’: Discourse Analysis and Social Psychological Peace Research

The present paper argues for a discourse analytic approach to social psychological peace research and demonstrates the potential of such an approach through a re‐specification of the concept of attitudes to war. This is illustrated through an analysis of a series of televised debates broadcast in the UK in February–March 2003 in the build‐up to the formal outbreak of the Iraq War. Analysis draws attention to the importance of rhetorical context and function, the inseparability of attitude object and evaluation and the formulation of evaluations as specific or general. Findings are discussed in the context of recent calls for methodological pluralism in social psychological peace research with a suggestion that matters of epistemology stand prior to methodology.

Let the pigeon drive the bus: pigeons can plan future routes in a room

The task of determining an optimal route to several locations is called the traveling salesperson problem (TSP). The TSP has been used recently to examine spatial cognition in humans and non-human animals. It remains unclear whether or not the decision process of animals other than non-human primates utilizes rigid rule-based heuristics, or whether non-human animals are able to flexibly ‘plan’ future routes/behavior based on their knowledge of multiple locations. We presented pigeons in a One-way and Round-Trip group with TSPs that included two or three destinations (feeders) in a laboratory environment. The pigeons departed a start location, traveled to each feeder once before returning to a final destination. Pigeons weighed the proximity of the next location heavily, but appeared to plan ahead multiple steps when the travel costs for inefficient behavior appeared to increase. The results provide clear and strong evidence that animals other than primates are capable of planning sophisticated travel routes.     

Counselling in the workplace: How time‐limited counselling can effect change in well‐being

Background: Many employers provide counselling support on work and personal issues for their employees, but in times of economic pressure such services can be at risk if their effectiveness is not demonstrated. Aim: To evaluate whether time‐limited counselling in a workplace can effect sustained change in well‐being. Method: The study was carried out by a staff counselling team in a university setting. The Warwick‐Edinburgh Mental Well‐being Scale (WEMWBS) was completed by clients at the beginning and end of counselling, and at three and six months following. A non‐treatment comparison group completed the survey at the same intervals. Results: The results of our investigation show clearly that the effect of time‐limited counselling (average seven sessions) on distressed clients is positive. The evidence of our treatment group suggests that they acquire an increased sense of well‐being as a result of the experience of counselling with a significant statistical difference between pre‐and post‐counselling treatment group scores on the WEMWBS and consistently higher scores found post counselling. The improvement was maintained at the same level for at least six months following the end of counselling. Conclusions: The provision of time‐limited counselling by employers is an effective support for personal difficulties affecting work.
