Are Ethics Training Programs Improving? A Meta-Analytic Review of Past and Present Ethics Instruction in the Sciences

Given the growing public concern and attention placed on cases of research misconduct, government agencies and research institutions have increased their efforts to develop and improve ethics education programs for scientists. The present study sought to assess the impact of these increased efforts by sampling empirical studies published since the year 2000. Studies published prior to 2000 examined in other meta-analytic work were also included to provide a baseline for assessing gains in ethics training effectiveness over time. In total, this quantitative review consisted of 66 empirical studies, 106 ethics courses, 150 effect sizes, and 10,069 training participants. Overall, the findings indicated that ethics instruction resulted in sizable benefits to participants and has improved considerably within the last decade. A number of specific findings also emerged regarding moderators of instructional effectiveness. Recommendations are discussed for improving the development, delivery, and evaluation of ethics instruction in the sciences.     

Mild Affective Shifts and Creativity: Effects on Idea Generation,Evaluation, and Implementation Planning

This study investigated the impact of mild shifts in affective tone (i.e., pleasant vs. unpleasant) and arousal (i.e., high vs. low) on three creative processes. Undergraduates read short stories designed to induce affective shifts and then were asked to generate solutions to a complex business problem. Shifts in affective tone and arousal interacted to influence idea generation and implementation planning, but not idea evaluation. The strongest creative performance was exhibited by participants who experienced a stable and pleasantly toned, low-arousal (i.e., relaxed) state and by those who shifted to an unpleasantly toned, high-arousal (i.e., angry) state. In contrast, those who shifted to an unpleasantly toned, low-arousal (i.e., sad) state or a pleasantly toned, high-arousal (i.e., happy) state tended to exhibit poorer creative performance. These results demonstrate the need to revisit the popular conception that organizations should promote intense levels of pleasant affect to enhance employee creativity.     

The nature of death and the death of nature: The impact of mortality salience on environmental concern

According to terror management theory, individuals are motivated to distinguish themselves from the rest of nature because doing so facilitates the denial of human mortality. However, based on an integration of terror management and contingencies of self-worth perspectives, the present research hypothesized that existential insecurities about death may differentially influence environmental concern depending on whether or not an individual derives self-esteem from environmental action. Results demonstrated that heightened mortality awareness led to less concern for the environment among those not deriving self-esteem from an environmental domain, but fostered environmental concern among those who do acquire self-esteem from environmental action. The implications of these findings are discussed.     

On the nonautomaticity of visual word processing: electrophysiological evidence that word processing requires central attention

The present study used event-related potentials (ERPs) to determine the degree to which people can process words while devoting central attention to another task. Experiments 1-4 measured the N400 effect, which is sensitive to the degree of mismatch between a word and the current semantic context. Experiment 5 measured the P3 difference between low- and high-frequency words. Because these effects can occur only if a word has been identified, both ERP components index word processing. The authors found that the N400 effect (Experiments 1, 3, and 4) and the P3 difference (Experiment 5) were strongly attenuated for Task 2 words presented nearly simultaneously with Task 1. No such attenuation was found when the Task 1 stimulus was presented but required no response (Experiment 2). Strong attenuation was also evident when the Task 2 word was presented before the Task 1 stimulus (Experiment 4), suggesting that central resources are not allocated to stimuli first-come, first-served but rather are strategically locked to Task 1. The authors conclude that visual word processing is not fully automatic but rather requires access to limited central attentional resources.     

Long-term aftereffects of response inhibition: memory retrieval, task goals, and cognitive control

Cognitive control theories attribute control to executive processes that adjust and control behavior online. Theories of automaticity attribute control to memory retrieval. In the present study, online adjustments and memory retrieval were examined, and their roles in controlling performance in the stop-signal paradigm were elucidated. There was evidence of short-term response time adjustments after unsuccessful stopping. In addition, it was found that memory retrieval can slow responses for 1-20 trials after successful inhibition, which suggests the automatic retrieval of task goals. On the basis of these findings, the authors concluded that cognitive control can rely on both memory retrieval and executive processes.     

The description and classification of presidential threateners

Presidential threateners who received court-ordered psychiatric evaluations at the Medical Center for Federal Prisoners in 1981 and 1982 were studied. Using data from psychiatric reports and other background documents, the cases were analyzed according to demographic, legal, and psychiatric variables. Cases were also classified according to a system based on the characteristics of the threatener and the context in which the threat was made.     

Indirect treatment of children via parent training: A burgeoning form of secondary prevention

This study reviews research on the process and outcome of parent training (PT) conducted over the past 20 years. A distinction is made between parent behavioral training and other forms of PT. It is concluded that all forms of PT research have become more molecular in the questions addressed and otherwise more scientifically rigorous. Compared to other forms of psychotherapeutic intervention, PT produces more consistently positive outcome changes and is clearly more economical of professional time and thus of consumer cost. As such, although less than 3% of all previous PT studies have dealt with prevention, PT is recommended as a potential form of secondary prevention worth consideration by applied and preventive psychologists.     

Awe and meaning: Elucidating complex effects of awe experiences on meaning in life

Research on the experience of awe suggests that awe has positive impacts on outcomes like life satisfaction and belongingness. No published work, however, has reported effects of awe on the experience of meaning in life. We reasoned that awe might have complicated effects on meaning. On the one hand, many awe experiences likely contain a positive flavor that contributes to both awe and general positive affectivity (happiness). Positive affectivity has a robust positive effect on meaning in life, suggesting that positive awe experiences might increase meaning. At the same time, however, awe experiences lead to a diminished self that reflects feelings of smallness and insignificance, which might negatively predict meaning. We thus hypothesized that awe experiences can, in some contexts, produce competing indirect effects on judgments of meaning in life through happiness and small-self feelings. The results of five studies (N = 1,690) supported these predictions.
