Good citizens to the end? It depends: empathy and concern with future consequences moderate the impact of a short-term time horizon on organizational citizenship behaviors

Organizational citizenship behaviors (OCBs) can be viewed as a social dilemma in which short-term employee sacrifice leads to long-term organizational benefits. With 3 studies, the authors evaluated a set of interrelated hypotheses based on a social dilemma analysis of OCBs. In Study 1, participants rated OCBs as costly to an employee in the short run and beneficial to an organization in the long run, indicating that OCBs were viewed as social dilemmas. In Studies 2 and 3, self-reported (Study 2) and supervisor-rated (Study 3) likelihood of engaging in OCBs was higher among those who adopted a long-term horizon within an organization and those high in empathy (M. H. Davis, 1983). Most important, a short-term time horizon led to a steeper decline in OCBs among employees low in empathy and those concerned with the future consequences of their actions.     

Being bad isn't always good: affective context moderates the attention bias toward negative information

Research has demonstrated that people automatically devote more attention to negative information than to positive information. The authors conducted 3 experiments to test whether this bias is attenuated by a person's affective context. Specifically, the authors primed participants with positive and negative information using traditional (e.g., subliminal semantic priming) and nontraditional (e.g., social interactions) means and measured the amount of attention they allocated to positive and negative information. With both event-related brain potentials (Experiment 1) and the Stroop task (Experiments 2 and 3), results suggest that the attention bias to negative information is attenuated or eliminated when positive constructs are made accessible. The implications of this result for other biases to negative information and for the self-reinforcing nature of emotional disorders are discussed.     

Teaching 'Yes' and 'No' responses to children with multiple disabilities through a program including microswitches linked to a vocal output device

The present study introduced two children (a boy and a girl of 9.2 and 12.3 yr. of age, respectively, with multiple disabilities) to an intervention program for establishing Yes and No responses in relation to preferred and nonpreferred stimuli and assessed the acquisition and generalization of those responses. The program involved the use of microswitches, which monitored the nonverbal Yes and No responses performed by the children and ensured that these responses produced the matching verbal utterances via a vocal output device. Analysis showed children acquired Yes and No responses in relation to the stimuli used for the intervention and, to a comparable degree, to the stimuli used for generalization checks as well. An interview of 30 educational staff of a center for persons with multiple disabilities indicated that they considered the presence of Yes and No verbal utterances preferable to the absence of such utterances, and thought that the utterances could be helpful for the children's response acquisition and would be useful and pleasing for staff and parents. General implications of the findings were discussed.     

A brief account of statistical tests for single-case research with persons with developmental disabilities

Education and rehabilitation research with persons with developmental disabilities is often based on single-case designs (with small numbers of ordinal data points collected at irregular intervals) and relies upon graphic display and visual inspection of the data. This paper (a) provides a brief account of some statistical tests, which may serve to supplement the visual inspection process and (b) underlines some of their strengths and limitations to help education and rehabilitation personnel make a reasonable choice among them.     

The physics of optimal decision making: a formal analysis of models of performance in two-alternative forced-choice tasks

In this article, the authors consider optimal decision making in two-alternative forced-choice (TAFC) tasks. They begin by analyzing 6 models of TAFC decision making and show that all but one can be reduced to the drift diffusion model, implementing the statistically optimal algorithm (most accurate for a given speed or fastest for a given accuracy). They prove further that there is always an optimal trade-off between speed and accuracy that maximizes various reward functions, including reward rate (percentage of correct responses per unit time), as well as several other objective functions, including ones weighted for accuracy. They use these findings to address empirical data and make novel predictions about performance under optimality.     

The Ethics of Killing in War

This paper argues that certain central tenets of the traditional theory of the just war cannot be correct. It then advances an alternative account grounded in the same considerations of justice that govern self-defense at the individual level. The implications of this account are unorthodox. It implies that, with few exceptions, combatants who fight for an unjust cause act impermissibly when they attack enemy combatants, and that combatants who fight in a just war may, in certain circumstances, legitimately target noncombatants who bear a significant degree of moral responsibility for a wrong, when the prevention or rectification of that wrong constitutes a just cause for war.

Dissociations between reaction times and temporal order judgments: a diffusion model approach

A diffusion model for simple reaction time (RT) and temporal order judgment (TOJ) tasks was developed to account for a commonly observed dissociation between these 2 tasks: Most stimulus manipulations (e.g., intensity) have larger effects in RT tasks than in TOJ tasks. The model assumes that a detection criterion determines the level of sensory evidence needed to conclude that a stimulus has been presented. Analysis of the performance that would be achieved with different possible criterion settings revealed that performance was optimal with a lower criterion setting for the TOJ task than for the RT task. In addition, the model predicts that effects of stimulus manipulations should increase with the size of the detection criterion. Thus, the model suggests that commonly observed dissociations between RT and TOJ tasks may simply be due to performance optimization in the face of conflicting task demands.     

Terror Management and Trait Empathy: Evidence that Mortality Salience Promotes Reactions of Forgiveness among People with High (vs. low) Trait Empathy

Terror management research has typically found that people respond harshly toward offending others when reminded of their mortality. In the current research we examined whether mortality salience would increase attitudes of forgiveness toward such individuals, especially among those with high trait empathy. Consistent with prior research, Study 1 showed that mortality salience increased forgiveness of a violent hockey player, but only if this person was a member of the ingroup. Study 2 showed that mortality (vs. dental pain) salience led persons high in trait empathy to forgive the same violent hockey player regardless of his group membership. Implications for increasing forgiveness and prosocial behavior in intergroup contexts are briefly discussed.

"I find you to be very attractive..." Biases in compliance estimates to sexual offers

The classic experiments by Clark and Hatfield on sex differences in compliance to offers of dates, apartment visits, and casual sex, and the related informal project of Molzer served as the foundation for the present study. However, whereas individuals in these previous investigations directly approached opposite-sex participants, our research employed surveys to gauge compliance. A sample of 195 male and 179 female Austrian adults were provided with written forms of the Clark and Hatfield scenarios and asked to predict the rates of compliance on a thermometer scale ranging from 0% to 100%. Results indicated that compliance estimates are largely effected by the sex of the receiver to these offers, and to a lesser degree, participants' age and relationship status. The sex of the participant did not significantly effect the results. Relative to the previous work, the compliance rate of males was overestimated, while that of females was underestimated. We offer explanations for the differences in findings between the original investigations and our research, discuss the importance of contextual factors as well as the generality of the Clark-Hatfield findings, especially with respect to females' near-zero receptivity to explicit sexual offers, and point out the relevance of the current findings for health psychology.
