The effects of mental contamination on the hindsight bias: Source confusion determines success in disregarding knowledge

We present data from eight experiments in which we explored the effects of source confusion on the hindsight bias; participants' success in disregarding information when they were instructed to do so was affected by participants' level of source confusion. In Experiment 1 we demonstrated participants' failure to disregard Revolutionary War information they recently learned while reading an essay; this failure to discount was not affected by participants' essay reading times (Experiment 1a). In Experiment 2 participants successfully discounted obscure War of 1812 information; this discounted information remained available in memory (Experiment 2a). In a direct test of source confusion (Experiment 3) we showed that participants discriminated between presented and not‐presented War of 1812 information better than they discriminated presented and not‐presented Revolutionary War information. In Experiments 4 and 4a we tested and rejected a motivational explanation for our findings, namely that subjects voluntarily withheld information when asked to disregard it. We tested a debiasing technique in Experiment 5 and found it was successful in helping participants discount familiar information. Results throughout are discussed as being attributable to source confusion. Copyright © 2008 John Wiley & Sons, Ltd.     

Cognitive-Behavioral Therapy for Adolescent Body Dysmorphic Disorder

The onset of appearance-related concerns associated with body dysmorphic disorder (BDD) typically occurs in adolescence, and these concerns are often severe enough to interfere with normal development and psychosocial functioning. Cognitive behavioral therapy (CBT) is an effective treatment for adults with BDD. However, no treatment studies focusing on adolescents with BDD have been conducted. The need for an effective treatment in this population led to the development of a brief CBT protocol with family involvement. The treatment focuses on enhancing an adolescent's quality of life through the reduction of maladaptive thoughts and behaviors, and incorporates skills training and parent training. Similar treatment packages have already been shown to be efficacious for children and adolescents with similar disorders, such as obsessive-compulsive disorder and social phobia. The following case illustrates the application of this brief CBT protocol for BDD in an adolescent, and highlights clinical considerations needed when adapting CBT for a pediatric population. Treatment was associated with clinically significant improvement in symptoms of BDD, self-esteem, depression, and quality of life. This report extends extant literature by suggesting that CBT may be a helpful treatment for adolescents with BDD.     

Documenting suicide risk assessments and proportionate clinical actions to improve patient safety and mitigate legal risk

Few clinical practices are as important for simultaneously augmenting patient safety and mitigating legal risk as the judicious evaluation and stratification of a patient's risk for suicide, proportionate clinical actions based thereon taken by the healthcare provider, and contemporaneous documentation of the foregoing. In this article, we draw from our combined decades of multidisciplinary experience as a clinical psychologist, forensic psychiatrist, medical malpractice attorney, and clinical psychology trainee to discuss the documentation of suicide risk assessment and management as a conduit to patient safety and legal risk mitigation. We additionally highlight documentation as a core clinical competency across disciplines and note areas of improvement, such as increased training, to bolster documentation practices.     

Jesus, Historians, and the Psychology of Historiography: A Response to My Respondents

It is remarkable to me that my book became a part of the SBL Dissertation Series. For this I thank Walter Wink who brought the work to the attention of, Wayne Rollins. And I am thankful to Wayne Rollins for bringing the book to the attention of the right people at the SBL, most particularly Rex D. Matthews and Mark Allan Powell. I am grateful to Mark Allan Powell for promoting the process of publication so we would have a book in hand at the Psychology and Biblical Studies book review session, now over two years ago. I am very appreciative of Lewis Rambo, editor of this journal, and J. Harold Ellens, special editor of this issue, for making possible the continued discussion of these ideas.     

The effects of predictive ability information,locus of control,and decision maker involvement on decision aid reliance

This study examines several factors that influence decision makers' willingness to rely on mechanical decision aids. The first experiment examined the effects of predictive ability information and locus of control on decision aid reliance. The results indicate that decision makers were more likely to rely on a decision aid when its predictive validity was not disclosed. Further, decision makers with an external locus of control relied more on the decision aid than those with an internal locus of control. The second experiment expanded upon this result to examine the interactive effects of decision maker involvement and locus of control. The results suggest that involving decision makers in the aid's development enhanced reliance. However, decision makers with an internal locus of control were more strongly influenced by this form of involvement (in terms of increasing their reliance on the decision aid) than decision makers with an external locus of control.

Practice dating as treatment for college dating inhibitions

Thirty males and 30 females who volunteered for a program to increase dating skills were randomly assigned to a treatment group of six practice dates plus feedback, a treatment group of six practice dates only, or a delayed treatment control group. Within subject-specified constraints of height, age, race, and distance from campus, a computer randomly matched opposite sexed subjects for the six practice dates, each date with a different subject. After each practice date in the feedback condition, subjects completed forms calling for primarily positive comments about the partner. Forms were later exchanged via the experimenter. Outcome was assessed by self-report, self-monitoring, behavioral, and peer rating measures. Results indicated the superiority of treatment conditions over the control condition. Some evidence indicated superiority of the no feedback condition over the feedback condition. Evidence of maintenance of changes over a three-month follow-up period is provided.     

Competence and the overjustification effect

The overjustification effect is manifested in decreased interest in an activity as a result of having been rewarded for participation in the activity. According to attribution theory's discounting principle, decreased interest occurs because the subject discounts the role of intrinsic motivation when a salient extrinsic reward is present. An alternative analysis based on the competence principle suggests that only rewards that convey no message of competence foster the overjustification effect, while manipulations that do convey competence information do not. A study crossing Reward (no reward-monetary reward) and Task Difficulty (hard-easy) supported the competence analysis. Subjects who succeeded on the hard task and thus felt competent manifested higher subsequent interest in the task. Consistent with the competence analysis, presence or absence of reward did not influence subsequent interest in the task.This research has been supported by a grant from the Ohio University Research Fund. I am grateful to Mark Henault, who served very ably as the experimenter. The hard work of Joel Ghitman and Craig Alexander is also gratefully acknowledged.
