The Association Between Sluggish Cognitive Tempo and Academic Functioning in Youth with Attention-Deficit/Hyperactivity Disorder (ADHD)

The purpose of the study was to evaluate the relation between Sluggish Cognitive Tempo (SCT) and academic functioning in a sample of 52 adolescents (40 males, 12 females) with Attention-Deficit/Hyperactivity Disorder (ADHD; M _age?=?13.75). This study builds on prior work by utilizing an empirically-based and psychometrically validated measure of SCT, collecting ratings of SCT from both parents and teachers, and examining associations with multiple domains of academic functioning from both the parent and teacher perspective as well as grade point average (GPA). Both SCT and DSM-IV symptoms of inattention were significantly correlated with domains of academic functioning. Multiple regression analyses demonstrated that the parent-rated SCT Slow subscale predicted overall academic functioning, organizational skills impairment, and homework problems above and beyond ADHD symptoms and child and demographic characteristics known to be associated with academics, including intelligence, academic achievement, and family income. The teacher-rated SCT Low Initiation/Persistence subscale also predicted homework problems and was the only SCT variable to predict school grades above and beyond ADHD symptoms and relevant covariates. Both the SCT Slow and Low Initiation/Persistence subscales include items related to youth seeming apathetic, unmotivated, and lacking initiative, behaviors that are strongly related to ADHD symptoms of inattention but not currently captured by the DSM-IV. Implications of these findings towards supporting the external validity of the SCT construct are discussed along with potential implications for intervention.     

The Long Arm of Mentoring: A Counterfactual Analysis of Natural Youth Mentoring and Employment Outcomes in Early Careers

Young people often develop natural mentoring relationships with nonparental adults during adolescence and young adulthood. While much has been learned about the benefits of natural mentoring for more proximate outcomes such as mental health and education, relatively little is known about the causal impact of youth mentoring relationships on career opportunities. This study uses data from the National Longitudinal Study of Adolescent Health (Add Health) survey to explore the effects of different kinds of natural mentoring relationships on employment outcomes during the early career years (when workers are in their late twenties and early thirties). Whereas traditional methods of causal conditioning show a broad range of employment benefits from being mentored, results from counterfactual analysis using propensity score matching reveal that the benefits of mentoring are confined to intrinsic job rewards. The findings imply that mentors help steer youth toward intrinsically rewarding careers.     

On the very concept of free will

Determinism seems to rule out a robust sense of options but also prevent our choices from being a matter of luck. In this way, free will seems to require both the truth and falsity of determinism. If the concept of free will is coherent, something must have gone wrong. I offer a diagnosis on which this puzzle is due at least in part to a tension already present in the very idea of free will. I provide various lines of support for this hypothesis, including some experimental data gathered by probing the judgments of non-specialists.     

Psychological Entitlement and Ambivalent Sexism: Understanding the Role of Entitlement in Predicting Two Forms of Sexism

Recent research has shown that narcissistic men in the United States express more ambivalent sexism than their non-narcissistic counterparts. The present study sought to extend these findings by hypothesizing that psychological entitlement would be a predictor of ambivalent sexism but that that this relationship may vary by gender. Given entitlement’s associations with hostility and aggression and the previously established link between narcissism and sexism in men, we hypothesized that entitlement would predict hostile sexism in men. Given that entitlement is characterized by a pervasive sense of deservingness for special treatment and goods, we expected that entitled women would endorse attitudes of benevolent sexism. These hypotheses were tested using two cross-sectional samples in the U.S.—a sample of undergraduates from a private university in the Midwest (N?=?333) and a web-based sample of adults across the U.S. (N?=?437). Results from regression analyses confirmed that psychological entitlement is a robust predictor of ambivalent sexism, above and beyond known predictors of sexism such as low openness and relevant covariates such as impression management. In addition, entitlement was a consistent predictor of benevolent sexism in women, but not in men, and a consistent predictor of hostile sexism in men, but not in women. These relationships were largely robust, persisting even when relevant covariates (e.g., socially desirable responding, trait openness) were controlled statistically, although in one sample the link between entitlement and hostile sexism in men was reduced to non-significance when benevolent sexism was controlled for statistically. Implications of these findings are discussed.     

Altering the Shape of Punishment Distributions Affects Decision Making in a Modified Iowa Gambling Task

Neuroeconomics research has shown that preference for gambling is altered by the statistical moments (mean, variance, and skew) of reward and punishment distributions. Although it has been shown that altered means can affect feedback‐based decision making tasks, little is known if the variance and skew will have an effect on these tasks. To investigate, we systematically controlled the variance (high, medium, and low) and skew (negative, zero, and positive) of the punishment distributions in a modified version of the Iowa Gambling Task. The Iowa Gambling Task has been used extensively in both academic and clinical domains to understand decision making and diagnose decision making impairments. Our results show that decision making can be altered by an interaction of variance and skew. We found a significant decrease over trials in choices from the decks with high variance and asymmetrically skewed punishments and from the decks with low variance and zero skew punishments. These results indicate that punishment distribution shape alone can change human perception of what is optimal (i.e., mean expected outcome) and may help explain what guides our day‐to‐day decisions.

The moral behavior of ethics professors: Relationships among self-reported behavior,expressed normative attitude,and directly observed behavior

Do philosophy professors specializing in ethics behave, on average, any morally better than do other professors? If not, do they at least behave more consistently with their expressed values? These questions have never been systematically studied. We examine the self-reported moral attitudes and moral behavior of 198 ethics professors, 208 non-ethicist philosophers, and 167 professors in departments other than philosophy on eight moral issues: academic society membership, voting, staying in touch with one's mother, vegetarianism, organ and blood donation, responsiveness to student emails, charitable giving, and honesty in responding to survey questionnaires. On some issues, we also had direct behavioral measures that we could compare with the self-reports. Ethicists expressed somewhat more stringent normative attitudes on some issues, such as vegetarianism and charitable donation. However, on no issue did ethicists show unequivocally better behavior than the two comparison groups. Our findings on attitude-behavior consistency were mixed: ethicists showed the strongest relationship between behavior and expressed moral attitude regarding voting but the weakest regarding charitable donation. We discuss implications for several models of the relationship between philosophical reflection and real-world moral behavior.     

Need to train your rat? There is an App for that: A touchscreen behavioral evaluation system

The increasing demand for highly automated and flexible tasks capable of assessing visual learning and memory in nonhuman animals has led to the exciting development of a wide array of prefabricated touchscreen-equipped systems. However, the high cost of these prefabricated systems has led many researchers to develop or modify their own preexisting equipment. We developed a freely downloadable App, the Touchscreeen Behavioral Evaluation System (TBES) for use in conjunction with an iPad (Apple, Cupertino, California) as an alternative to prefabricated touchscreen systems. TBES allows for stimulus presentation and data collection on an iPad. The touchscreen technology offered by the iPad is attractive to researchers due to its affordability, reliability, and resistance to false inputs. We highlight these, as well as the feasibility and procedural flexibility of TBES, in an effort to promote our system as a competitive alternative to those currently available.     

Impact of Sluggish Cognitive Tempo and Attention-Deficit/Hyperactivity Disorder Symptoms on Adults’ Quality of Life

The symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) have been linked to dysfunction in numerous life domains for both children and adults. As such, it is likely that individuals with these and other related symptoms (e.g., sluggish cognitive tempo, SCT) may also experience impaired quality of life. The current study examines the association between ADHD and SCT symptoms and quality of life (QOL) in a community sample of adults. Quality of life data collected from 983 participants (M age = 45.6 years) were analyzed primarily through a series of hierarchical multiple regressions employing SCT and ADHD symptom clusters, demographic, and anxiety and depression scale variables as predictors. Results generally supported the hypothesis that ADHD and SCT symptoms would negatively associate with QOL. Amongst the indicators, inattention and SCT emerged as the strongest predictors of low QOL. These findings underscore the negative impact of ADHD symptoms in adulthood, the independent contribution of SCT, and the importance of considering QOL in prospective research and intervention.     

Review of the Evidence for Motivation Deficits in Youth with ADHD and Their Association with Functional Outcomes

Preeminent theories of attention-deficit/hyperactivity disorder (ADHD) suggest that motivation deficits are core underlying features of the disorder. However, it is currently unclear whether empirical evidence supports the assertion that significant group (ADHD v. comparison) differences in motivation exist or that problems with motivation contribute to the functional impairments that youth with ADHD experience. Accordingly, this review focused on evaluating and summarizing the empirical literature on the presence of motivation deficits and their association with functional outcomes in samples of youth with ADHD. Twenty studies met the review inclusion criteria. Results support the assertion that youth with ADHD have lower academic-related motivation in comparison to their peers and that motivation plays an important role in academic outcomes, with the strongest evidence to date for reading achievement. However, the available evidence is limited, and few existing studies are aligned with the much larger theoretical and empirical motivation literature in typically developing youth. Given preliminary evidence that motivation plays a role in the academic impairments of youth with ADHD, the review concludes with a discussion of whether current ADHD interventions adequately target motivation and highlights important future directions.
