Weak ventral striatal responses to monetary outcomes predict an unwillingness to resist cigarette smoking

As a group, cigarette smokers exhibit blunted subjective, behavioral, and neurobiological responses to nondrug incentives and rewards, relative to nonsmokers. Findings from recent studies suggest, however, that there are large individual differences in the devaluation of nondrug rewards among smokers. Moreover, this variability appears to have significant clinical implications, since reduced sensitivity to nondrug rewards is associated with poorer smoking cessation outcomes. Currently, little is known about the neurobiological mechanisms that underlie these individual differences in the responsiveness to nondrug rewards. Here, we tested the hypothesis that individual variability in reward devaluation among smokers is linked to the functioning of the striatum. Specifically, functional magnetic resonance imaging was used to examine variability in the neural response to monetary outcomes in nicotine-deprived smokers anticipating an opportunity to smoke—circumstances found to heighten the devaluation of nondrug rewards by smokers in prior work. We also investigated whether individual differences in reward-related brain activity in those expecting to have access to cigarettes were associated with the degree to which the same individuals subsequently were willing to resist smoking in order to earn additional money. Our key finding was that deprived smokers who exhibited the weakest response to rewards (i.e., monetary gains) in the ventral striatum were least willing to refrain from smoking for monetary reinforcement. These results provide evidence that outcome-related signals in the ventral striatum serve as a marker for clinically meaningful individual differences in reward-motivated behavior among nicotine-deprived smokers.     

Competence in everyday activities as a predictor of cognitive risk and mortality

This study examined the association of a performance-based measure of everyday functioning with clinically meaningful outcomes. Elderly participants in a prospective study of dementia were assessed at two occasions on the Everyday Problems Test for Cognitively Challenged Elderly (EPCCE), a performance-based measure of everyday functioning. Older adults who remained cognitively intact performed approximately 0.66 SD units higher on the EPCCE at both occasions than elders rated as impaired, when covarying on age, education, gender, and cognitive status. Relative to the nonimpaired participants, decline in EPCCE performance over a 2-year interval was significantly greater for impaired participants and those participants who transitioned from nonimpaired to impaired over the course of the study. Increased risk of mortality was associated with lower baseline scores and decline in EPCCE performance even after controlling for demographic variables and performance on the Mini-Mental State Examination. Given the clinical importance of identifying "at risk" elders for impairment, the findings from this study provide initial evidence for the predictive utility of performance-based measures of everyday functioning.     

Tendency to catastrophize somatic sensations: pain catastrophizing and anxiety sensitivity in predicting headache

General catastrophic thinking styles about uncomfortable bodily sensations may predispose the development of common health pathologies, such as persistent headache. The purpose of this research was to explore the relationships between the Pain Catastrophizing (PC) Scale and Anxiety Sensitivity (AS) Index, which measure tendencies to catastrophize pain- and anxiety-related somatic sensations, respectively. A non-clinical sample completed the PC Scale, AS Index, and health outcome questionnaires regarding headache (n = 1018). Results revealed that: (i) AS and PC are empirically separate constructs; (ii) the overlap between PC and AS lies within the domain of fearing physical catastrophe; (iii) AS independently predicts weekly headache, headache pain intensity, and the number of a wide range of physical symptoms associated with headache; and (iv) PC independently predicts the presence of weekly headache. Limitations and implications of this research, as well as recommendations for future research directions are discussed.     

A Reliability Generalization Study of Coefficient Alpha for the Life Orientation Test

The Pd, K and L scales of the MMPI and four of Kolberg's Moral Judgment Situations were administered to three criterion groups; adolescent delinquents, college students, and individuals belonging to a therapy collective which provides free community service. Greater than 50% of both the delinquent and therapy collective subjects were classified as psychopathic, (Pd + K T score > 70). The three subject groups obtained significantly different moral maturity scores with the therapy collective subjects receiving the highest moral maturity mean score. The results of two stepwise regression analyses found no relationship between Pd scores and moral maturity scores.     

The Varieties of Wonder

Although wonder is a response to what is extraordinary or regarded as such, this covers a variety of things. Hence, wonder covers a spectrum from mere surprise or puzzlement to stronger responses like dread or amazement; moreover, it is often linked to other powerful responses like fear or admiration, and it can lead people into many pursuits and areas of reflection. I look at the variety of the objects of wonder, and of the neighbouring responses and conceptual connections found here, then I discuss the response of wonder itself, and its causes and effects. Finally, I ask why the sense of wonder can atrophy, and whether it can be suppressed deliberately.     

Latent self-oriented and socially prescribed perfectionism: Tests of factorial,convergent, and discriminant validity using self- and informant reports

Using latent variables for self-oriented perfectionism (i.e., demanding perfection of oneself) and socially prescribed perfectionism (i.e., perceiving others are demanding perfection of oneself) has advantages. However, few studies have specifically examined the psychometric properties of these latent variables. The present study addresses this shortcoming by testing the factorial, convergent, and discriminant validity of self-oriented and socially prescribed perfectionism latent variables using self- and informant reports. It was hypothesized that (a) the factor structure of the self-oriented and socially prescribed perfectionism latent variables would be supported, (b) self- and informant reports would moderately converge, and (c) the self-oriented and socially prescribed perfectionism latent variables would be discriminable. A sample of 242 undergraduate women and 378 informants (218 mothers, 160 fathers) was recruited. Undergraduate women completed self-reports, and mothers and fathers completed informant reports. Results were consistent with hypotheses, thereby supporting (a) the factorial validity of the self-oriented and socially prescribed latent variables using self- and informant reports, (b) the convergent validity of the self-oriented and socially prescribed latent variables via moderately to strongly correlated self- and informant reports, and (c) the discriminant validity of the self-oriented and socially prescribed perfectionism latent variables. Findings suggest research using these latent variables is warranted.     

Do interpersonal features of social anxiety influence the development of depressive symptoms?

This study is a prospective examination of possible interpersonal features of social anxiety that might predict increases in depressive symptoms. It was hypothesised that social anxiety would be associated with avoidance of expressing emotion, lack of assertion, and interpersonal dependency and that these dysfunctional interpersonal styles would predict depressive symptoms one year later while controlling for Time 1 depressive symptoms. One hundred and two undergraduates completed interview and self-report measures of these interpersonal styles in addition to measures of social anxiety and depressive symptoms. Results indicated that social anxiety was associated with all three interpersonal styles. However, only avoidance of expressing emotions predicted Time 2 depressive symptoms. Theoretical implications of these results are discussed.     

“I Tried to Make it not Confusing by Fixing it”: Describing Six First Graders’ Use of Strategies to Understand Text

This study describes six first-grade students’ use of metacognitive strategies. The students (4 boys and 2 girls) represented low, average, and above-average readers and were enrolled in a rural Midwestern elementary school. A variety of data were collected throughout the year: (a) an informal reading inventory and metacognitive awareness interview were conducted at the beginning and end of the year; and (b) during the school year, think-aloud interview protocols, running records, anecdotal notes, and retellings were conducted. The analysis revealed that these first graders were reporting and using a variety of strategies to read.     

Cosmetic Surgery: Feminist Perspectives

Cosmetic surgery is gaining popularity not only in the U.S., but worldwide. The sheer number of procedures being performed makes it seem “normal,” and in the statistical sense it is. Feminist therapists are likely to have clients who are contemplating undergoing one or more of these procedures. Therapists ought to help their clients to understand the motivations underlying a decision to undergo surgery for the sake of improving on nature. In the final analysis, the decision belongs to the woman who may be placing her life at risk to achieve some desired end. The therapist can play a role in helping her to weigh the risks and what will be accomplished in the end.
