Discriminative control of punished stereotyped behavior in humans

The purpose of this experiment was to establish discriminative control of responding by an antecedent stimulus using differential punishment because the results of past studies on this topic have been mixed. Three adults with mental retardation who exhibited stereotypy not maintained by social consequences (i.e., automatic reinforcement) participated. For each subject, stereotypy occurred frequently in the presence of a stimulus correlated with nonpunishment of stereotypy and rarely, if ever, in the presence of a stimulus correlated with punishment of stereotypy. Latency measures showed that the antecedent stimulus correlated with punishment served as the discriminative stimulus for the suppression of stereotypy. These results are important insofar as they show that discriminative control by an antecedent stimulus develops with punishment, and because it sometimes may be desirable to establish such control of socially inappropriate behavior.     

Deteriorating memory confidence, responsibility perceptions and repeated checking: comparisons in OCD and control samples

Repeated checking has been repeatedly associated with memory distrust. We sought to extend previous research using a computer-based checking task by incorporating a group of 15 individuals with OCD, and examining the effect of increased perceived responsibility. Participants were asked to repeatedly check a virtual stovetop, with half the participants also placed under a condition of high-perceived responsibility. Our observations replicated previous research showing that the act of repeatedly checking leads to reductions in memory vividness, detail and confidence, without accompanying reductions in memory accuracy. Furthermore, while a sense of increased personal responsibility had little effect on a student control sample, it led to a significant further deterioration in memory confidence in individuals with OCD. These results suggest that in people with OCD, normal reductions in memory confidence over repeated trials are exacerbated and intensified by inflated responsibility perceptions.     

The Irrelevance of Democracy to the Public Justification of Political Authority

Democracy can be a means to independently valuable ends and/or it can be intrinsically (or non-instrumentally) valuable. One powerful non-instrumental defence of democracy is based on the idea that only it can publicly justify political authority. I contend that this is an argument about the reasonable acceptability of political authority and about the requirements of publicity and that satisfying these requirements has nothing to do with whether a society is democratic or not. Democracy, then, plays no role in publicly justifying political authority. I also show that any non-instrumental defence of democracy must make claims about what justice requires and make several further claims that require substantial justification.

Choking on the Money: Reward-Based Performance Decrements Are Associated With Midbrain Activity

ABSTRACT— A pernicious paradox in human motivation is the occasional reduced performance associated with tasks and situations that involve larger-than-average rewards. Three broad explanations that might account for such performance decrements are attentional competition (distraction theories), inhibition by conscious processes (explicit-monitoring theories), and excessive drive and arousal (overmotivation theories). Here, we report incentive-dependent performance decrements in humans in a reward-pursuit task; subjects were less successful in capturing a more valuable reward in a computerized maze. Concurrent functional magnetic resonance imaging revealed that increased activity in ventral midbrain, a brain area associated with incentive motivation and basic reward responding, correlated with both reduced number of captures and increased number of near-misses associated with imminent high rewards. These data cast light on the neurobiological basis of choking under pressure and are consistent with overmotivation accounts.     

Moderating and Intensifying Factors Influencing Forgiveness by Priests and Lay People

Factors that influence forgiveness were studied in relation to sexual abuse of children by priests. This study used a series of scenarios measuring conceptualization of forgiveness. The Santa Clara Strength of Religious Faith (Plante and Boccaccini 1997) was used to assess the strength of religious faith. Priests were more forgiving of the abusive priest and of the church than lay Catholics. Higher levels of spirituality were associated with likelihood to forgive. Forgiveness was more likely under moderating factors of one time abuse, apology, reconciliation, and life change, than under their intensifying matches. Results were discussed in terms of conflict resolution.     

Psychology's limits as a scientific discipline: A personal view

I provided a more personal view of Wachtel's (1980) article. I began by discussing the extent to which my own research program complied with his distinctive recommendations. After offering a different take on the impact of high productivity, I focused on (a) the negative effects of the quest for extramural funding and (b) the positive effects of a better balance between theoretical and empirical contributions. I then turn to some of my own theoretical and empirical studies of the place that theory has in successful science. This research suggests that theory only has a beneficial effect when it is integrative in function and when it is closely constrained by available data. I end with a speculation regarding the value of having theories that are maximally formal, even mathematical.     

Randomized controlled evaluation of an early intervention to prevent post-rape psychopathology

A randomized between-group design was used to evaluate the efficacy of a video intervention to reduce post-traumatic stress disorder (PTSD) and other mental health problems, implemented prior to the forensic medical examination conducted within 72 h post-sexual assault. Participants were 140 female victims of sexual assault (68 video/72 nonvideo) aged 15 years or older. Assessments were targeted for 6 weeks (Time 1) and 6 months (Time 2) post-assault. At Time 1, the intervention was associated with lower scores on measures of PTSD and depression among women with a prior rape history relative to scores among women with a prior rape history in the standard care condition. At Time 2, depression scores were also lower among those with a prior rape history who were in the video relative to the standard care condition. Small effects indicating higher PTSD and Beck Anxiety Inventory (BAI) scores among women without a prior rape history in the video condition were observed at Time 1. Accelerated longitudinal growth curve analysis indicated a videoxprior rape history interaction for PTSD, yielding four patterns of symptom trajectory over time. Women with a prior rape history in the video condition generally maintained the lowest level of symptoms.     

Precision and accuracy of judgmental estimation

Whereas probabilistic calibration has been a central normative concept of accuracy in previous research on interval estimates, we suggest here that normative approaches for the evaluation of judgmental estimates should consider the communicative interaction between the individuals who produce the judgments and those who receive or use them for making decisions. We analyze precision and error in judgment and consider the role of the accuracy–informativeness trade-off (Yaniv and Foster, 1995) in the communication of estimates. The results shed light on puzzling findings reported earlier in the literature concerning the calibration of subjective confidence intervals. © 1997 John Wiley & Sons, Ltd.     

Group Artistic Creativity: Creative Clusters and Cinematic Success in Feature Films1

Filmmaking represents a distinctive form of group creativity in which many individuals contribute to a single creative product. This exploratory investigation examines these contributions in 1,327 English‐language, narrative feature films. Besides control variables, the measures included 2 criteria of impact (Best Picture honors, movie guide ratings) and 16 assessments of outstanding cinematic contributions (direction, male and female lead, male and female supporting, screenplay, art direction, costume design, makeup, cinematography, film editing, score, song, visual effects, sound effects editing, sound). A factor analysis showed that the contributions formed 4 creative clusters: dramatic, visual, technical, and musical. Hierarchical regression analyses indicate that a film's impact was a positive additive function of the dramatic and visual clusters, with the dramatic having the primary role.
