Direct Comparison of Episodic Encoding and Retrieval of Words: An Event-related fMRI Study

Functional magnetic resonance imaging (fMRI) was used to compare directly episodic encoding and retrieval. During encoding, subjects studied visually presented words and reported via keypress whether each word represented a pleasant or unpleasant concept (intentional, deep encoding). During the retrieval phase, subjects indicated (via keypress) whether visually presented words had previously been studied. No reliable differences were found during the recognition phase for words that had been previously studied and those that had not been studied. Areas preferentially active during encoding (relative to retrieval) included left superior frontal cortex, medial frontal cortex, left superior temporal cortex, posterior cingulate, left parahippocampal gyrus, and left inferior frontal gyrus. Regions more active in retrieval than encoding included bilateral inferior parietal cortex, bilateral precuneus, right frontal polar cortex, right dorsolateral prefrontal cortex, and right inferior frontal/insular cortex.     

Moral worry and religiosity in US and Canadian college samples

The objective of this study was to investigate the presence of worry about personal moral attitudes and behaviors in two college samples, and to check associations with religiosity, age, gender, personality traits, and geographic region. The study sample was drawn from college students in Minneapolis, Minnesota (N?=?333) and Sydney, Nova Scotia (N?=?137). Instruments consisted of moral worry and religiosity questionnaires, and the Eysenck Personality Questionnaire. Principal-components analysis was used to develop components for the worry and religiosity scales, and MANOVA for correlations between variables. Moral worry emerged as a domain distinct from worry about practical issues. Moral worry was not related to religiosity, age, gender, or Eysenck personality traits. Whereas the US sample scored higher in religiosity than the Canadian sample, the Canadian sample scored higher on moral worry. The present study supports our previous work and that of others that worry about one's moral emotions and behaviors is an important aspect of daily life. As such, consideration should be given to including some inquiry about moral worries (guilt, shame, regret, remorse, and others) in psychiatric assessments.     

Personality and Fears

The contribution to self-reported fears of individual differences in extraversion-introversion (E) and neuroticism (N) was studied in 102 female college students. Four groups of 20 Ss each were constituted - high E high N, high E low N, low E high N, and low E low N. A fear survey schedule and the Eysenck Personality Inventory were employed. By analysis of variance, total fear scores were a significant function of N but not E. Extreme or phobic fears were a significant function of neither personality dimensions, though the N effect approached conventional significance levels. Correlational analyses on the full sample confirmed these findings, except that a statistically significant though slight (6 percent) proportion of extreme fear variance was accountable by N.     

The Relationship Between Childhood Trauma,Combat Exposure,and Posttraumatic Stress Disorder in Male Veterans

The current study investigated the effects of combat exposure, childhood trauma, and depression on posttraumatic stress disorder (PTSD) severity. Participants were 299 male veterans from the Korean War, World War II, Vietnam, and the first Gulf War who were being screened for admission to the PTSD unit. Participants were assessed with the Clinician-Administered PTSD Scale (CAPS), Combat Exposure Scale (CES), Hamilton Depression Rating Scale (HAMD), Childhood Trauma Questionnaire (CTQ), and Mississippi Scale for PTSD (MPTSD). Results of multiple regression analyses indicated that, as expected, combat exposure and depression were significant predictors of PTSD severity. When examined with combat exposure, childhood trauma has a complex relationship to PTSD severity. Examination of the interaction between the CES and CTQ suggests that when levels of combat are low and childhood trauma levels are high, the CTQ is related to higher levels of PTSD severity on the CAPS, regardless of depression. Treatment implications are discussed.     

A Limited Information Estimator for Dynamic Factor Models

Structural equation modeling (SEM) is an increasingly popular method for examining multivariate time series data. As in cross-sectional data analysis, structural misspecification of time series models is inevitable, and further complicated by the fact that errors occur in both the time series and measurement components of the model. In this article, we introduce a new limited information estimator and local fit diagnostic for dynamic factor models within the SEM framework. We demonstrate the implementation of this estimator and examine its performance under both correct and incorrect model specifications via a small simulation study. The estimates from this estimator are compared to those from the most common system-wide estimators and are found to be more robust to the structural misspecifications considered.     

Health Programming for Clergy: An Overview of Protestant Programs in the United States

The health of clergy is important, and clergy may find health programming tailored to them more effective. Little is known about existing clergy health programs. We contacted Protestant denominational headquarters and searched academic databases and the Internet. We identified 56 clergy health programs and categorized them into prevention and personal enrichment; counseling; marriage and family enrichment; peer support; congregational health; congregational effectiveness; denominational enrichment; insurance/strategic pension plans; and referral-based programs. Only 13 of the programs engaged in outcomes evaluation. Using the Socioecological Framework, we found that many programs support individual-level and institutional-level changes, but few programs support congregational-level changes. Outcome evaluation strategies and a central repository for information on clergy health programs are needed.     

What people desire, feel conflicted about, and try to resist in everyday life

In the present study, we used experience sampling to measure desires and desire regulation in everyday life. Our analysis included data from 205 adults, who furnished a total of 7,827 reports of their desires over the course of a week. Across various desire domains, results revealed substantial differences in desire frequency and strength, the degree of conflict between desires and other goals, and the likelihood of resisting desire and the success of this resistance. Desires for sleep and sex were experienced most intensively, whereas desires for tobacco and alcohol had the lowest average strength, despite the fact that these substances are thought of as addictive. Desires for leisure and sleep conflicted the most with other goals, and desires for media use and work brought about the most self-control failure. In addition, we observed support for a limited-resource model of self-control employing a novel operationalization of cumulative resource depletion: The frequency and recency of engaging in prior self-control negatively predicted people's success at resisting subsequent desires on the same day.     

Mapping Gray’s BIS and BAS constructs onto Factor 1 and Factor 2 of Hare’s Psychopathy Checklist – Revised

Reinforcement sensitivity theory (RST; Gray, 1987; Gray & McNaughton, 2000) has proven to be a valuable tool for understanding psychopathy (e.g., Fowles, 1980, 1988; Newman & Malterer, 2009; Poythress et al., 2008). Recent research has linked two RST constructs, the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS), to individuals with primary psychopathy and secondary psychopathy (Lykken, 1995; Newman, MacCoon, Vaughn, & Sadeh, 2005): Primary psychopaths manifest low BIS reactivity and secondary psychopaths manifest high BAS reactivity. In the present study, we examine the relationships between the BIS/BAS constructs and Factors 1 and 2 of the Psychopathy Checklist – Revised (PCL-R) in a sample of 472 incarcerated male offenders. Paralleling their relationships with primary and secondary psychopathy, the BIS/BAS constructs were differentially related to the two PCL-R factors. Specifically, the influence of the BIS was found to be more prominent than the influence of the BAS for Factor 1, and the influence of the BAS was more prominent than that of the BIS for Factor 2.     

A component analysis of a parent‐conducted multi‐component treatment for food selectivity

Treatment packages including differential reinforcement of alternative (DRA) behavior and escape prevention in the form of a non‐removal of the spoon procedure have been shown to successfully increase food consumption. However, when these treatment components are introduced simultaneously, the treatment component(s) responsible for behavior change cannot be determined. The purpose of this study was to conduct a sequential component analysis of the following treatment components: Bite fading, manipulation of reinforcer magnitude, and escape prevention. For two participants, food consumption did not increase until after escape prevention was introduced. For one participant, increased food consumption was observed after the magnitude of reinforcement was increased; therefore, escape prevention was not necessary. Results were maintained at a 12‐week follow‐up for all participants. Copyright © 2010 John Wiley & Sons, Ltd.     

When fit fosters favoring: The role of private self-focus

The present research extends work on the ‘the value from fit’ principle by showing that regulatory fit effects on persuasion and behavioral compliance are stronger for people high, as opposed to low, in private self-focus. Previous research has shown that people high in private self-focus are strongly affected by external information. In the current work, we demonstrated that people high (vs. low) in private self-focus are more persuaded by information that matches (vs. mismatches) activated self-knowledge.
