Retrospective Frequency Formats Promote Consistent Experience‐Based Bayesian Judgments

On the basis of their experiences with pregnant patients in their practice, obstetrician/gynecologists estimated the posterior probability of Down syndrome given a positive screening result. They also estimated the base rate of Down syndrome in their practice, along with the hit and false alarm rates for the screening test; for each subject, these numbers were combined to calculate a posterior probability to which the initial estimated posterior probability could be compared. Physicians gave highly consistent estimates when asked to think about their past experiences in terms of event frequencies. However, those told to respond using single event probabilities or to use past experiences to predict prospective frequencies gave inconsistent Bayesian estimates. Thus, when making Bayesian judgments based on real life experience, natural frequency formats only lead to better judgments, compared with single event probability formats, if people think retrospectively, not when using past experiences to make prospective predictions.

Shooting the Messenger: The Case of ADHD

Medicating ADHD is a controversial subject that was acutely inflamed in 1995 when high rates of ADHD diagnosis and treatment were documented in southeastern Virginia. Psychologists in southeastern Virginia formed a regional school health coalition to implement and evaluate interventions to address the problem. Other professionals with strong ties to the pharmaceutical industry launched ad hominem attacks on the coalition’s research and work. These attacks contributed to the work being terminated in 2005. In the ensuing years, ADHD drug treatment continued to escalate. Today, the national rate of ADHD diagnosis exceeds all reasonable estimates of the disorder’s true prevalence, with 14 % of American children being diagnosed before reaching young adulthood. Notable key opinion leaders continue to claim that there is no cause for concern, but with a message shift from “the prevalence is not too high” to “high prevalence is not too concerning.” This paper provides an object lesson about how innovative research can be derailed to the detriment of sound medical and mental health care of children when industry interests are threatened. Tenure may be the only option for protecting innovative research from specious attacks. The authors offer a summary of the data on ADHD drug treatments, suggest judicious use of such treatments, and add their voices to others who are once again sounding a cautionary alarm.     

Forgiveness and Health in Christian Women

Researchers in psychology have studied the influence of forgiveness on the both the psychological and physical health of individuals. In addition, parish nursing is also looking at forgiveness as a potential benefit for self-care and health promotion. Forgiveness was measured using Enright’s Forgiveness Inventory. Health was measured using Spielberg’s State/Trait Anger measure, Beck’s II Depression measure, SPF-15 Health Survey. Body Mass Index was also calculated. Mixed Methods was also used to describe the qualitative findings using content analysis on the types of unjust violations Christian women experienced. Women expressed very severe unjust violations involving sexual, physical, emotional, financial and spiritual abuse. Statistical correlations suggested important relationships among forgiveness and overall health measures warranting further investigation. The relationship between Church type and forgiveness raised questions about women’s role in the Church as well as, the importance of acknowledging personal feelings, which are excluded in many orthodox denomination’s doctrines.     

An Intensive Summer Treatment Program for ADHD Reduces Parent–Adolescent Conflict

There are currently almost no treatment efforts to reduce parent–adolescent conflict in adolescents with ADHD. As such, this study investigated the effect of an intensive Summer Treatment Program for Adolescents with ADHD (STP-A) on parent–adolescent conflict. Twenty adolescents and their parents completed the 8 week behavioral treatment program, which included 320 hours of adolescent-directed treatment, 15 hours of parent behavior management training, and daily feedback from staff on parent implementation of a home-based behavioral contract. Results indicated that 70–85 % of adolescents who attended the STP-A demonstrated reliable improvement in parent–adolescent conflict from baseline to post-treatment. Treatment response was associated with higher levels of conflict at baseline, but not adolescent ODD severity or parent ADHD severity. Several patterns of treatment non-response were detected through visual examination of weekly conflict scores during the STP-A. Discussion suggests that intensive, parent-involved treatment programs may be necessary to improve home-conflict in adolescents with ADHD.     

Who got vaccinated against H1N1 pandemic influenza? – A longitudinal study in four US cities

The recent H1N1 pandemic influenza stimulated numerous studies into the attitudes and intentions about the H1N1 vaccine. However, no study has investigated prospective predictors of vaccination behaviour. We conducted a two-wave longitudinal study among residents in four US cities during the course of the H1N1 outbreak, using Internet surveys to assess demographic, cognitive and emotional predictors of H1N1 vaccination behaviour. Surveys were conducted at two time points, before (Time 1) and after (Time 2) the H1N1 vaccine was widely available to the public. Results show that Time 2 vaccination rates, but not Time 1 vaccination intentions, tracked H1N1 prevalence across the four cities. Receipt of seasonal influenza vaccine in the previous year, worry, compliance with recommended interventions, household size and education assessed at Time 1 were significant prospective predictors of vaccination behaviour. Perception of the H1N1 vaccine, social influence and prioritised vaccine recipient status assessed at Time 2 also predicted vaccination behaviour. Critically, worry about H1N1 mediated the effects of both objective risk (prevalence at the city level) and perceived risk on vaccination behaviour. These results suggest that H1N1 vaccination behaviour appropriately reflected objective risk across regions, and worry acted as the mechanism by which vaccination behaviour followed objective risk.     

Cycloheximide produces amnesia for extinction and reconsolidation in an appetitive odor discrimination task in rats

A considerable literature has shown deficits in memory resulting from the administration of protein synthesis inhibitors; however, most of the past literature in this field has focused on acquisition of new memory using aversively-motivated tasks. The effect of protein synthesis inhibition on appetitive learning and memory as well as extinction is less clear. The present study employed an appetitive odor discrimination paradigm to examine the effects of acute cycloheximide administration (1 mg/kg) on reconsolidation and extinction.Male, Long-Evans adult rats were trained to discriminate between two odors (i.e., cocoa and cinnamon) and then received extinction trials following an intraperitoneal injection of cycloheximide or vehicle. Twenty-four hours later, rats were tested via one non-reinforced test trial. Results showed amnesia for extinction as well as original training (i.e., correct odor choice) in cycloheximide-injected rats in this appetitive task, while vehicle-injected controls showed good memory for extinction. These data add to a growing literature showing the importance of protein synthesis inhibition for extinction and reconsolidation in appetitive learning and memory.     

The making of a tragedy: perversion in the perception of truth

A type of wilful blindness can pervert an individual's perception of truth or reality, not because that reality is too much to hold, but because it is distasteful. Undesired. The case of Adam will be used to explore perversion as it twists an analytic process, affecting the transference and countertransference in ways that are difficult to see. Theorists of Freudian, Kleinian, Lacanian, and Jungian traditions are drawn from to explore potential roots to this perverted turn, and the way it can rigidify an individuation process. The anxiety that haunts this case echoes Jung's anxiety as he wondered if the stone saw him or he saw the stone. Object and observer blend when both analyst and patient hide from themselves and one another, knowing the truth of what is being discussed but blind to it.     

The Limit of Mental Structures

The development of consistent health behaviors is important for chronic illness prevention and management. The current study experimentally compared two strategies—a personal-rule and a deliberation strategy—designed to help participants consistently perform their intended behaviors over a 7-week period in a real-world setting. Although the personal-rule strategy had theoretical support from behavioral economics and empirical support from both animal and human lab experiments, the deliberation strategy group was significantly more successful than the personal-rule strategy group, both initially (time to first violation, p < .01, Cohen's d = .51) and over the entire 7-week period (overall success, p < .05, Cohen's d = .18). These effects were significant even after controlling for known predictors of behavioral success, including individual-difference variables, person-behavior factors, and resolution-related factors.     

Perceived Benefits and Challenges of a Multiethnic-Racial Identity: Insight From Adults With Mixed Heritage

The purpose of this inquiry was to explore the lived experiences of multiethnic-racial individuals (i.e., individuals with parents from different ethnic-racial groups). In-depth interviews were conducted with 29 adults from the United States with mixed ethnic-racial backgrounds ranging in age from 18 to 52 (female n = 20, male n = 9). We identified a number of themes related to perceived benefits (e.g., pluralistic world views, stronger sense of self) and challenges (e.g., identity tensions, communal concerns) of having a mixed heritage. Findings are discussed in terms of four considerations for ethnic-racial identity of individuals with mixed ethnic-racial backgrounds: emphasizing constellations of experiences, life-span and developmental considerations of identity, (mixed) ethnic-racial identity as constituted in interactions, and the potential promise of pluralistic world views.
