Is the Association of ADHD with Socio-Economic Disadvantage Explained by Child Comorbid Externalizing Problems or Parent ADHD?

It has been unclear whether an associations of child ADHD with socio-economic disadvantage (SES) could be accounted for by (a) parental ADHD explaining both low SES and child ADHD, and/or (b) the joint overlap of ODD or CD with low SES and ADHD. Study 1 used a community-recruited case-control sample with detailed evaluation of SES indicators, child ADHD, child externalizing, and parent ADHD symptoms (n = 931 children, 521 ADHD, 577 boys, 354 girls) in a path modeling analysis with latent variables. Study 2 evaluated ADHD and externalizing behavior in a regression model using a poverty index for SES, in 70,927 children (48.2% female) aged 5–17 years from the US 2011–2012 National Survey of Children’s Health (NSCH). In Study 1, lower SES was related to the ADHD latent variable, β = ?.18, p < .001; 95%CI [?.25,-.12]. This effect held when parent ADHD and child ODD and CD were in the model, β = ?.11, p < .01, 95% CI [?.09,-.03], equivalent to OR = 1.50, 95% CI[1.12–2.04]). In Study 2, these results replicated. Adjusting only for age and sex, children from families who were below 200% of the federal poverty line were more likely to have moderate or severe ADHD than no ADHD, versus children above that line, OR = 2.13, 95% CI[1.79,2.54], p < .001. The effect held after adjusting for disruptive/externalizing problems, OR = 1.61, p < .01, 95%CI [1.32,1.96]. The effect size for comparable models was similar across both studies, lending higher confidence to the results. It is concluded that the SES association with child ADHD is not explained by artifact and requires a mechanistic explanation.     

What is the Role of the Arts in Medical Education and Patient Care? A Survey-based Qualitative Study

To inform medical education reform efforts, we systematically collected information on the level of arts and humanities engagement in our medical school community. Attitudes regarding incorporating arts and humanities-based teaching methods into medical education and patient care were also assessed. An IRB-approved survey was electronically distributed to all faculty, residents, fellows, and students at our medical school. Questions focused on personal practice of the arts and/or humanities, as well as perceptions of, and experience with formally incorporating these into medical teaching. Of 13,512 community members surveyed, 2,775 responded (21% overall response rate). A majority of respondents agreed or strongly agreed that medical education and patient care could be "enhanced" by the integration of the arts (67% and 74% respectively). There was enthusiastic support for the creation of a formal program in the arts at our medical school (72 %). Integration of the arts into medical education may have a role in improving the quality of medical training and would likely be well received by teachers and learners.     

Socrates’ Aversion to Being a Victim of Injustice

In the Gorgias, Plato has Polus ask Socrates if he would rather suffer injustice than perform it. Socrates’ response is justly famous, affirming a view that Polus himself finds incredible, and one that even contemporary readers find difficult to credit: “for my part, I would prefer neither, but if it had to be one or the other, I would choose to suffer rather than do what is unjust” (Gorgias 469c1-2). In this paper, we take up the part of Socrates’ response that Polus never engages and that has also been completely neglected by contemporary scholars, namely, Socrates’ explicit aversion to being a victim of injustice. We show that this same aversion—though one not nearly as strong as his aversion to doing injustice—appears in several texts, and we argue that the best explanation of such an aversion derives from two important features of Socratic philosophy, both of which have only recently been recognized in Socratic scholarship: (i) his virtue intellectualism, which conceives of virtue as a kind of craft that can be achieved in different degrees, and (ii) his conception of moral psychology, which allows for non-rational influences on how we perform the cognitive functions required for proper deliberation.     

Skill-based differences in option generation in a complex task: a verbal protocol analysis

In recent models of decision-making, cognitive scientists have examined the relationship between option generation and successful performance. These models suggest that those who are successful at decision-making generate few courses of action and typically choose the first, often best, option. Scientists working in the area of expert performance, on the other hand, have demonstrated that the ability to generate and prioritize task-relevant options during situation assessment is associated with successful performance. In the current study, we measured law enforcement officers’ performance and thinking in a simulated task environment to examine the option generation strategies used during decision-making in a complex domain. The number of options generated during assessment (i.e., making decisions about events in the environment) and intervention (i.e., making decisions about personal courses of action) phases of decision-making interact to produce a successful outcome. The data are explained with respect to the development of a situational representation and long-term working memory skills capable of supporting both option generation processes.     

Evaluating the endophenotype model of ADHD neuropsychological deficit: results for parents and siblings of children with ADHD combined and inattentive subtypes

Neurogenetic models predict neuropsychological weaknesses in the relatives of children with attention-deficit/ hyperactivity disorder (ADHD). The authors examined executive and regulatory measures in 386 relatives (307 parents, 79 siblings) of children with ADHD combined type, ADHD inattentive type, and controls. Predicted deficits were seen on trailmaking (relatives of ADHD combined type only), stop-signal reaction times (relatives of girls only), and response variability (mothers only) but not on naming or output speed. Effects generally held, even with relatives' ADHD status controlled. A neuropsychologically impaired subgroup of children with ADHD had relatives with clear neuropsychological weaknesses. The authors conclude that a neurogenetic model of ADHD etiology is supportable only for a subset of executive functions and that neuropsychological heterogeneity warrants more examination in ADHD.     

Inferences about the authentic self: when do actions say more than mental states?

Three studies involving 478 undergraduates examined the perceived importance of observable actions versus mental states in revealing the "true self"-the authentic and fundamental nature of a target person. Results suggest that when people have only limited information about a target, they believe that an action is more diagnostic of the individual's true self than the accompanying mental state. When participants have knowledge concerning chronic dispositional tendencies of the target, however, they judge that a chronic mental state is more diagnostic of the true self than a chronic action tendency. Considered together, the findings suggest that people conceptualize the true self as a relatively private entity but nevertheless believe that an action of a little-known person may be particularly informative about that individual. Perceived diagnosticity of the true self was partially mediated by inferences concerning the relative stability of actions versus states but not by inferences of volition.     

Recognizing the centrality of gender identity and stereotype knowledge in gender development and moving toward theoretical integration: reply to Bandura and Bussey (2004)

Most of the critique in the A. Bandura and K. Bussey (see record 2004-18097-001) commentary is a misunderstanding or misrepresentation of the points made by C. L. Martin, D. N. Ruble, and J. Szkrybalo in their 2002 Psychological Bulletin article (see record 2002-18663-003). First, Martin et al. never intended to present a comprehensive theory; instead, it was a review of 2 different cognitive approaches to gender development. Second, there is no time line test that has been failed; instead, gender cognitions may occur earlier than initially believed. Third, Bandura and Bussey dismissed central gender cognitions-gender identity and gender stereotype knowledge-despite considerable evidence in their support. Fourth, Bandura and Bussey never addressed the gaps and ambiguities inherent in their theory that Martin et al. questioned in their earlier article. Finally, Bandura and Bussey's misunderstandings of cognitive theorists' views on socialization agents, sociocultural influences, agency, and motivation created theoretical rifts where none exist.     

Effects of self-evaluation on the P300 event-related potential

The effects of self evaluation on the P300 event-related potential (ERP) were explored with 56 participants (16 men, 40 women; M age = 23.4 yr., SD = 1.2) across three conditions. The conditions included (1) a standard ERP auditory oddball discrimination between a random target (15% occurrence) and standard stimuli (85% occurrence), (2) the oddball task followed by the additional cognitive task of maintaining a mental count of the target tones, and (3) the oddball task followed by the additional cognitive task of self-evaluating whether they felt surprised by the current occurrence of the target tone. The added cognitive requirements for Conditions 2 and 3 required the subjects to maintain a cognitive readiness for the secondary stimulus-related task during their sensory discrimination response for the standard oddball task. During the self-evaluation condition, the P300 amplitude was significantly larger across all recording locations than the regular oddball condition and the cognitive count condition.
