A computer program for Spearman-K?rber and probit analysis of psychometric function data.

PMETRIC is a computer program for the analysis of observed psychometric functions. It can estimate the parameters of these functions, using either probit analysis (a parametric technique) or the Spearman-K?rber method (a nonparametric one). For probit analysis, either a maximum likelihood or a minimum chi 2 criterion may be used for parameter estimation. In addition, standard errors of parameter estimates can be estimated via bootstrapping. The program can be used to analyze data obtained from either yes-no or m-alternative forced-choice tasks. To facilitate the use of PMETRIC in simulation work, an associated program, PMETGEN, is provided for the generation of simulated psychometric function data. Use of PMETRIC is illustrated with data from a duration discrimination task.     

Theatre and Research in the Reproductive Sciences

This paper explores the power of theatre to engage the public and my personal journey using theatre as a research tool in reproductive science. I argue that the capacity of theatre to simultaneously engage the minds and hearts of audience members qua research participants affords audience members the capacity to provide researchers with insightful comments informed by the scientific, social and tacit knowledge derived from the performance, integrated with their lived experience. Theatre is a particularly important research strategy when investigating public understandings and desires about complex issues such as those related to reproductive and genetic science.     

Subjective reports of stimulus,response, and decision times in speeded tasks: How accurate are decision time reports?

Four experiments examined how accurately participants can report the times of their own decisions. Within an auditory reaction time (RT) task, participants reported the time at which (a) the tone was presented, (b) they decided on the response, or (c) the response key was pressed. Decision time reports were checked for plausibility against the actual RTs, and we compared the effects of experimental manipulations on these two measures to see whether the reported decision times showed appropriate effects. In addition, we estimated the amount of error associated with individual decision time reports by checking how often participants’ decision time reports were implausibly early (i.e., before stimulus onset) or late (i.e., after response), and by using several quantitative models. Overall, the results suggest that decision time reports are not very accurate but they may be usable for some purposes.     

Animalism and the varieties of conjoined twinning

We defend the view that we are not identical to organisms against the objection that it implies that there are two subjects of every conscious state one experiences: oneself and one’s organism. We then criticize animalism—the view that each of us is identical to a human organism—by showing that it has unacceptable implications for a range of actual and hypothetical cases of conjoined twinning: dicephalus, craniopagus parasiticus, and cephalopagus.

Stigma against false confessors impacts post‐exoneration financial compensation

False confessors are stigmatized more than other exonerees. Traditional theories of stigma suggest that this difference may result from confessors being seen as more responsible for their own wrongful conviction. In the current study, we examined an important tangible consequence of stigma against false confessors—namely, that it might impede their ability to win financial restitution in post‐exoneration civil lawsuits. Mock jurors (N = 129), recruited online, read a case summary in which an exoneree is seeking damages after being wrongly convicted due to a false confession or eyewitness misidentification, which either did or did not result from police misconduct. When the exoneree falsely confessed in the absence of police misconduct, mock jurors rated him as most responsible for his own conviction and expressed the most doubt over his actual innocence. Contrary to legal criteria, they also awarded him smaller compensatory and punitive damage awards. Notably, the false confessor was seen as more responsible than the misidentified exoneree even if his interrogation was highly coercive. In turn, false confessors who were seen as more responsible received smaller damage awards. Implications for trial procedure and exoneree compensation are discussed.     

The Political Activity of Evangelical Clergy in the Election of 2000: A Case Study of Five Denominations

This article focuses on the political participation of ministers from five evangelical Protestant denominations that differ in theology, polity, and history. Despite such differences, these clergy respond to political influences in much the same fashion. We find that the standard theories of political participation have varying success in accounting for their political involvement. Sociodemographic explanations provide little help, but psychological engagement with politics has more explanatory power. Professional role orientations are the best predictors of actual participation. And the clergy who see moral reform issues as the most important confronting the country—and who hold conservative views on such issues—are most likely to become engaged. Finally, membership in Christian Right organizations serves to elicit more activity than might occur if ministers were left to internally motivated participation. Despite the emphasis on other contextual variables in some work on clerical politics, we find that communications exposures, congregational influences, and even the support of clerical colleagues have very limited independent effects on political involvement.     

What Happens When Therapists Feel Bored or Anxious? A Qualitative Study of Distracting Self-Awareness and Therapists' Management Strategies

Using a qualitative methodology, we investigated novice and experienced therapists' experiences of and strategies for managing distracting self-awareness. We found that novice therapists were most aware of anxiety and critical self-talk, whereas experienced therapists were most aware of boredom and outside distracters. In addition, although therapists tended to manage distracting self-awareness through self-coaching and refocusing on the client, novice therapists specifically mentioned managing problematic self-awareness through self-disclosure. In contrast, experienced therapists tended to manage problematic self-awareness by using thought stopping techniques. The results provide new avenues for examining therapists' in-session experiences and for investigating the effectiveness of different management strategies.     

Teens on the Internet—commercial application of a deconstructive analysis of ‘teen zine’ features

This paper presents the authors' approach to understanding drivers of interest for teen e‐zines (Internet magazines). The paper shows how a deconstruction of the current set of e‐zines provides the raw material for a conjoint measurement study, whereby the elements are mixed and matched in order to create new test concepts. From reactions to those test concepts one can identify four newly emerging segments: the ‘indifferents’, the ‘adults in training’, the ‘media and me’ and the ‘talk and celebrate being a teen’. Deconstruction applied to the competitive frame provides both a deeper understanding of the e‐zine landscape and input for newer and better e‐zines that are targeted to specific mindsets.
