Sacrificing one to save many

Attempts to solve the Trolley Problem by means of a single principle have proved unpersuasive. Nor can the intuition about Transplant be adequately grounded in the hypothetical dissent of rational contractors. It is explained by the initial liability principle, that loss should lie where it falls unless there is sufficient reason to shift it. If we did not think we should accept misfortune in such cases and thought that minimising loss of life was sufficient reason to shift the loss we should not be according others the minimum respect and treatment we feel is their due. The intuition about Trolley is explained by the affinity of that case to the pure case where the choice is between saving many and saving fewer, where minimising misfortune is the only credible option. But these considerations are not yet enough to accommodate the cases that lie between the extremes of Trolley and Transplant. We can handle the intermediate cases by attempting to assimilate them to one or other paradigm and to one another with a sensitivity to morally relevant and irrelevant differences that seeks initially to be faithful to the values reflected by our moral intuitions. Those intuitive judgements are unlikely to survive such an examination wholly unmodified.     

One, two, three, many - Subitizing in active touch

‘Subitizing’ refers to rapid and accurate judgement of small numbers of items, while response times and error rates increase rapidly for larger set-sizes. Most enumeration studies have been done in vision. Enumeration studies in touch have mostly involved ‘passive touch’, i.e. touch without active exploration. In daily life a much more common situation is that of ‘active touch’, e.g. when we count the number of coins in our pocket. To investigate numerosity judgement in active touch, we let subjects haptically explore varying numbers of spheres. Our results show that enumeration for up to 3 items is more efficient than for larger numbers of items. We also show that enumeration in this regime was not performed through estimation. Furthermore, it is shown that numerosity information was accessed directly and not through mass or volume cues. Not only do our results show that a haptic version of subitizing exists in active touch, they also suggest similar underlying enumeration mechanisms across different modalities.     

Selecting one among many referents in spatial situation models

Five experiments related anaphor resolution to a classic memory variable, namely, interference created by multiple uses of a given object-concept, and by spatial distance of the referent from the reader's focus of attention. Participants memorized a diagram of a building with rooms containing objects, and then read narratives describing characters' activities there. Reading was self-paced word by word. Accessibility was measured by readers' time to understand anaphoric sentences containing a definite noun phrase referring to an object in its room. Spatial distance between the object and the current focus of attention increased reading times for names of the object, the room, and sentence wrap-up. Multiple examples of a target-object increased its reading time only if they were scattered across different rooms. An associative model of memory retrieval during text comprehension was used to interpret the complex pattern of results.     

Hospital ethics committees: One of many centers of responsibility

Ethical reality is coextensive with human dignity. Therefore, one essential way to understand ethics is as the systematic effort to discern the imperatives of human dignity. Seeing ethics in this way highlights the fact that health care institutions have many centers of ethical responsibility (CERs) — the Chief Executive Officer, Board of Trustees, senior management team, etc. The Ethics Committee is only one such CER and not the most important one. These other CERs will benefit from identifying: (1) the fact that they are consistently dealing with ethical reality and making ethical decisions; (2) some critical elements of good ethical decision-making: (i) having the appropriate community; (ii) making the guiding value priorities explicit and specific; (iii) gaining skill in using the needed intellectual tools; and (iv) fashioning appropriate process and structure for discernment.     

Reinvestment in one versus one in-field and shoot-out field hockey performance

The theory of reinvestment suggests that inappropriate use of attention to consciously engage in movements or decisions (movement specific reinvestment or decision specific reinvestment) can result in disrupted performance. We used moderation analysis to investigate the association between these forms of reinvestment and performance during one versus one in-field and shoot-out scenarios during field hockey. We expected that the propensity for reinvestment would be negatively associated with shoot-out performance but not in-field performance, because monitoring many other players during in-field play diverts attention away from conscious engagement in movements or decisions. No association was evident between decision specific reinvestment and in-field or shoot-out performance. However, a higher propensity for movement specific reinvestment (specifically, conscious motor processing) was negatively associated with shoot-out performance, but not in-field performance. We speculate that the necessity to shift between many non-static attentional demands during in-field situations may reduce capacity for movement specific reinvestment during performance.     

Genes, brain, and behavior: Bridging disciplines

With excitement surrounding the publication of the human genome, scientists have set out to uncover the functions of specific genes. This special issue on Genes, Brain, and Behavior attempts to present research strategies that connect major avenues of genetic research across disciplines. For example, anatomical information provided by brain imaging can serve as a convenient link between anatomical abnormalities seen in knockout/transgenic mouse models and abnormal patterns of brain activity seen in certain patient populations. Identifying genetic risk factors for disorders with carefully designed cognitive assays is another strategy that has gained increasing attention. These approaches are being combined with behavioral studies of mouse models of gene function. Alone, each of these approaches provides limited information on gene function in complex human behavior, but together, they are forming bridges between animal models and human psychiatric disorders.     

Adaptive self-regulation of unattainable goals: goal disengagement, goal reengagement, and subjective well-being

Three studies examined associations between goal disengagement, goal reengagement, and subjective well-being. In Study 1, 115 undergraduates reported on the extent to which they were able to abandon unattainable goals and reengage their efforts in alternative goals. Study 2 examined the importance of goal disengagement and goal reengagement in groups of young adults and older adults (N = 120). In Study 3, a sample of parents of children with cancer and parents of medically healthy children was examined (N = 45). The findings confirmed that goal disengagement and goal reengagement can be associated with ratings of high subjective well-being. In addition, the results showed that goal disengagement and goal reengagement can have interactive effects on subjective well-being. The importance of the findings for effective self-regulation and successful development are discussed.     

The influence of monetary incentives on goal choice,goal commitment,and task performance

This study was designed to investigate the mechanism by which monetary incentives influence goal choice, goal commitment, and task performance. It is hypothesized that the explanation for incentive effects on goals and performance is in their influence on mediating events. A model attempting to explain the process of goal choice, work motivation, and performance in terms of cognitions is presented. Subjects were recruited for 5 days of part-time employment in a simulated organization to perform a clerical data transfer task. The 130 subjects were assigned randomly to 7 experimental conditions differing in terms of the magnitude of incentive offered for various levels of performance. The quantity and quality of performance was recorded daily and research questionnaires were administered at different times during their employment. Results provide support for the model presented and therefore suggest that the process of goal choice and commitment is central to understanding how incentives influence goals, motivation, and performance. The model provides a useful basis for investigating the relationships between organizational context and employee cognitions and for integrating goal setting with expectancy theory. The findings and future research issues are discussed.     

The role of implicit motivation in hot and cold goal pursuit: Effects on goal progress, goal rumination, and emotional well-being

Two cross-sectional studies examined the role of implicit motivational needs in the association between personal goal pursuits and depressive symptoms and affect. Replicating and extending on findings reported by Brunstein et al. [Brunstein, J. C., Schultheiss, O. C., & Grässmann, R. (1998). Personal goals and emotional well-being: The moderating role of motive dispositions. Journal of Personality and Social Psychology, 75(2), 494–508], both studies provided evidence that goal progress significantly accounted for variations in depressive symptoms and happiness only in individuals with high levels of implicit motivation, but not in individuals low in implicit motivation. Moreover, in the absence of a strong sense of goal commitment, high levels of implicit motivation were associated with high goal progress in both studies and low levels of goal rumination in Study 2. These findings are interpreted within a dual-systems framework of motivation that distinguishes an implicit, intuitive, and hedonically driven from an explicit, effortful-analytical, and non-hedonic mode of goal pursuit.     

The relationship between learning goal orientation,goal setting,and performance: a longitudinal study

In an educational setting, we examined the relationship of learning goal orientation with goal setting and performance over time. At the first time point, we assessed levels of trait learning goal orientation and asked participants to set performance goals. At each follow‐up time point, we reported to participants their current course grade and allowed them to revise their goals. Learning goal orientation was associated with both setting higher goals and maintaining higher performance over time. Additionally, the relationship of learning goal orientation and performance was found to be mediated by goal setting.     

The relation between goal adjustment,goal disturbance,and mental well-being among persons with multiple sclerosis

Objective: This study investigated the role of goal adjustment, i.e. disengaging from blocked goals and reengaging into alternative goals, in mental well-being and goal disturbance in persons with multiple sclerosis (MS).

Design: A cross-sectional design was used with self-report data from questionnaires and Personal Project Analysis (PPA).

Main outcome measures: Dependent variables were mental well-being, indicated by depression/anxiety (HADS; Hospital Anxiety and Depression Scale) and mental functioning (SF-36; Short Form Health Survey), and goal disturbance, indicated by goal manageability and goal interference (PPA). Independent variables were patient-reported physical impairment (SF-36) and goal disengagement and reengagement (GAS; Goal Adjustment Scale).

Results: Higher goal reengagement was associated with better mental well-being, but unrelated to goal disturbance. Goal disengagement only showed a negative association with anxiety. High disengagement was associated with lower goal interference but only for those also scoring high on reengagement. Goal adjustment did not buffer the effects of physical impairment on mental well-being and goal disturbance. Contrary to expectations, higher goal reengagement increased the association between physical impairment and goal interference.

Conclusion: Although goal reengagement is associated with better mental well-being in persons with MS, it might also strengthen the perceived effect of physical impairment on goal interference.     

The influence of component participation and role models on goal acceptance, goal satisfaction, and performance

The present investigation examined the effects of different types of participation (choice) and role models in goal setting on goal acceptance, goal satisfaction, and performance. It was hypothesized that choice in setting a goal and a strategy to achieve the goal would positively benefit goal acceptance, performance, and goal satisfaction. In addition, it was predicted that a role model would differentially influence an individual's goal acceptance, goal satisfaction, and performance. One hundred twenty male college students working on a class scheduling task were exposed to either a high- or low-performing role model and given various amounts of choice in the goal-setting process. The results of two-way analyses of variance demonstrated that goal acceptance, goal satisfaction, and performance were highest for individuals given choice over their goal and their strategy to achieve the goal. In addition, the results demonstrated that an individual exposed to a high-performing role model outperformed and had higher goal acceptance and satisfaction than an individual exposed to a low-performing model. The results are discussed as a means for clarifying the effects of different types of choice in the goal-setting process and the importance of role-provided information in influencing an individual's performance.
