Probabilistic Mental Models with Continuous Predictors

Gigerenzer and his colleagues have sought to develop psychologically plausible models of human judgment. Their models are classified as ones of bounded rationality based on a principle of one-reason decision making. The models associated with the theory of Probabilistic Mental Models (PMM) have been developed for tasks in which all predictors are binary. This article extends PMM to the case of continuous predictors. The current model employs the limitation on the number of categories people use in making absolute judgments along a single perceptual dimension (7 +/- 2; Miller, 1956). The algorithm transforms each continuous predictor to be consistent with this limitation, then implements a step-down one-reason decision procedure similar to previous PMM models. Like previous PMM models, the 7 +/- 2 model predicts binary judgments as well as a multiple-regression model. However, the model does not successfully predict the probability judgments of individual participants, which is also true of all other models in the literature. Copyright 2000 Academic Press.     

“亚当·斯密问题”的逻辑张力

“亚当·斯密问题”是指斯密的《国富论》与《道德情操论》之间存在着对立或不一致的问题,最初由十九世纪中叶的德国历史学派所提出。此后,随着现实与理论的发展,出现了不同的看法。学者们普遍认为,斯密的两大著作之间、经济学与伦理学之间存在着对立或者不存在对立,而是相互一致的。这些看法都具有各自的积极合理的内容,但缺乏辩证的观点,而没有看到“斯密问题”自身的逻辑张力,也就是说,“斯密问题”所指涉的是现实的经济与伦理之间及作为其理论表现的经济学与伦理学之间的关系。“斯密问题”所含的这些关系呈现出了一个动态的、由肯定到否定再到否定之否定的辩证过程。     

Information and discriminability as determinants of absolute judgment choice reaction time

The integration of information model of signal detection theory (SDT) was tested in a multiple observation tilt-discrimination task. Improvement in discriminability with additional observations was consonant with theory over two observations, but observations beyond the second yielded less improvement than predicted by the integration model. Analyses of operating characteristics lent some support to the applicability of SDT to the tilt-discrimination task.     

The effect of memory color on form identification

Previous studies have demonstrated that a form’s identity affects the phenomenal hue of that form. This effect has been attributed to the operation of the “memory color” phenomenon. The present study was proposed to assess the effect of “memory” or characteristic color on form identification. Results indicate that memory color, rather than interacting with the object in such a manner as to aid identification, induces a bias toward identification of an object of the memory color.     

Construct validity for the verbal associated pairs screen

The present study introduces the Verbal Associated Pairs Screen (VAPS) as a new measure for assessing performance validity in pediatric populations. This study presents initial data on psychometric properties and establishes construct validity for the VAPS in a sample of 30 adolescent healthy controls and 206 youths with traumatic brain injury (TBI: moderate/severe, N = 30; mild, N = 176). The control group’s age (M = 14.93, SD = 1.8) was significantly higher than the moderate/severe TBI (M = 13.9, SD = 2.8), t(68.508) = ?3.038, p = .003, and mild TBI (mTBI) groups (M = 14, SD = 2.8), t(54.147) = 2.038, p = .046. The TBI groups were administered the VAPS in accord with other established performance validity tests (PVTs) and well-established memory tests as part of routine clinical evaluations. The healthy control group was administered the VAPS only. VAPS score distributions for the control group were negatively skewed and highly kurtotic. VAPS scores from the moderate/severe TBI and control groups were indistinguishable for Trial 2 (U = 274, p < .01) and the Delay (U = 396, p = .218). In the mTBI group, convergent and divergent validity was established with other well-validated PVTs and memory tests, respectively. ROC curve analyses identified optimal cutoff scores for the VAPS Total Score, with acceptable sensitivity (55%) and excellent specificity (100%), as well as strong detectability (AUC = .829, 95% CI: 0.731 – 0.928, p < .001). Clinical applications, limitations, and directions for future research with the VAPS are discussed.     

Measuring Emotional Intelligence Enhances the Psychological Evaluation of Chronic Pain

The assessment of emotional factors, in addition to other psychosocial factors, has been recommended as a means of identifying individuals with chronic pain who may not respond to certain pain treatments. Systematic reviews of the evidence regarding the prediction of responsiveness to a treatment called the spinal cord stimulator (SCS) have yielded inconclusive results. Emotional intelligence is a term which refers to the ability to identify and manage emotions in oneself and others and has been shown to be inversely associated with emotional distress and acute pain. This study aims to investigate the relationship between emotional intelligence, chronic pain, and the more established psychosocial factors usually used for SCS evaluations by clinical psychologists in medical settings. A sample of 112 patients with chronic pain on an acute hospital waiting list for SCS procedures in a pain medicine service were recruited. Psychological measures were completed including: a novel measure of emotional intelligence; usual measures of emotional distress and catastrophizing; and a numerical rating scale designed to assess pain intensity, pain-related distress, and interference. As predicted, findings revealed significant associations between most of the measures analyzed and current pain intensity. When entered into a simultaneous regression analysis, emotional intelligence scores remained the only significant predictor of current pain intensity. There are potential clinical, ethical, and organizational implications of emotional intelligence processes partially predicting pain in patients on a waiting list for a medical procedure. These results may offer new insight, understanding, and evaluation targets for clinical psychologists in the field of pain management.     

Making sense of male rape: constructions of gender,sexuality and experience of rape victims

This study reports a preliminary investigation into accounting practices for male rape in conversation. Thirty men and women, in dyads, were asked to discuss an incident of male rape presented to them in a vignette. The findings showed that two main issues were discussed: the experience of the rape act and societal responses to male victims. In addition, participants established a ‘hierarchy of suffering’, where rape was judged to be worse for ‘heterosexual’ men than it is for ‘women’ or ‘gay’ men. Hegemonic, phallocentric representations of heterosexuality were mobilized to argue that acts of rape and consensual intercourse are the same for ‘gay’ men and ‘women’ and therefore less traumatic than for ‘heterosexual’ men. This obscures the violence of rape for gay men and women and exonerates perpetrators by minimizing injury sustained. Participants also argued that heterosexual victims are likely to experience ridicule for having departed from hegemonic masculinity. Arguments were constructed to avoid charges of being dismissive towards women and gay men and of victim blaming in relation to heterosexual men. Copyright © 2004 John Wiley & Sons, Ltd.     

An outcome evaluation study of a psycho‐educational course in a primary care setting

Rationale: To date relatively little research has examined the effectiveness of psycho‐educational courses provided in a primary care setting to adults with mild‐to‐moderate mental health concerns. Aims: To determine whether group psycho‐education could be a viable alternative to individual counselling by (1) assessing the clinical effectiveness of an 8‐week psycho‐educational course, and (2) examining the group outcomes in comparison with individual treatment outcomes from a previous study in the same counselling service. Method: A total of 57 participants attending a psycho‐educational course provided data over a 36‐month period, using the Clinical Outcomes in Routine Evaluation – Outcome Measure (CORE‐OM) pre‐ and post‐intervention. A comparison was then made with the data of 58 previous participants of individual counselling evaluation, using the same CORE‐OM system. Results: Participants reported significantly lower levels of psychological distress after attending the course and these results are comparable to outcomes measured in the same service for individual counselling, indicating that group interventions could be considered a legitimate alternative to individual counselling, thus increasing cost effectiveness and reducing waiting times. Limitations of the study and implications for practice and further investigation are considered.
