Assessing inattention and impulsivity in children during the Go/NoGo task

Behavioural performance in the Go/NoGo task was compared with caregiver and teacher reports of inattention and hyperactivity‐impulsivity in 1,151 children (N=557 boys; N=594 girls) age 9–10 years old. Errors of commission (NoGo errors) were significantly correlated with symptom counts of hyperactivity‐impulsivity, while errors of omission (Go errors) were significantly correlated with symptom counts for inattention in both caregiver and teacher reports. Cross‐correlations were also evident, however, such that errors of commission were related to inattention symptoms, and errors of omission were related to hyperactivity‐impulsivity. Moreover, hyperactivity‐impulsivity and inattention symptoms were highly intercorrelated in both caregiver (r=.52) and teacher reports (r=.70), while errors of commission and omission were virtually uncorrelated in the Go/NoGo task (r=.06). The results highlight the difficulty in disentangling hyperactivity‐impulsivity and inattention in questionnaires, and suggest that these constructs may be more clearly distinguished in laboratory measures such as the Go/NoGo task.     

The Development of Price Formation Theory and Subjectivism about Ultimate Values

abstract One sometimes finds leading economic thinkers expounding the metaphysical thesis that the ultimate ethical value of an object reflects nothing about the properties of the object in itself and instead reflects the subjective tastes of the valuer. Could anything in economics qua economics provide a warrant for such ethical subjectivism? And what might tempt economists to speak on such broadly meta‐ethical issues? In this paper we argue that a partial explanation for the subjectivist cast‐of‐mind of much economic theory is to be found in the recent history of price formation theory. (We focus in particular on the so‐called ‘Marginalist’ and ‘Ordinalist’ Revolutions in price theory.) We argue that although such price formation theory provides no warrant for drawing ethical subjectivist conclusions, it does provide an explanation as to why such conclusions might be drawn. Thus we explore how the particular history of the development of what is called ‘value theory’ might well lead one (albeit unwarrantedly) towards ethical subjectivism.     

Postdeployment Suicide Risk Increases Over a 6‐month Period: Predictors of Increased Risk among Midwestern Army National Guard Soldiers

National Guard (NG) soldiers returning from deployments in Iraq and Afghanistan were surveyed at 6 and 12 months following their return (N = 970). The overall prevalence of suicide risk at 6 and 12 months following their return was assessed, as were changes in suicide risk among soldiers initially at high or low risk. Factors associated with changes in risk were assessed. The percentage of NG soldiers with high suicide risk increased from 6.8% at 6 months to 9.2% at 12 months (odds ratio = 1.7, p = .02). In the 882 soldiers initially at low risk, 5.9% (52/882) became high risk at 12 months; in the 64 soldiers initially at high risk, 46.9% (30/64) became low risk at 12 months. Initial levels of depressive symptoms were predictive of changing to high risk; this association appeared to be partially explained by soldier reports of increased search in the meaning in life and higher levels of perceived stress. Because suicide risk increases over the first 12 months, continued risk assessments during this time period should be considered. Supporting soldiers to find meaning in their life after deployment and enhancing their capacity to cope with perceived stress may help prevent increases in suicide risk over time.     

Refugees in the media: Exploring a vicious cycle of frustrated psychological needs,selective exposure,and hostile intergroup attitudes

Two research objectives underlay the present research. First, we tested how frustrated psychological needs caused by the refugee-influx influence the endorsement and selection of refugee-relevant information. Second, we tested how information selection processes contribute to the development of exclusionary attitudes that counteract the integration of refugees into host countries. In a laboratory study (n = 181), frustrated psychological needs decreased participants’ endorsement of a refugee-friendly essay (vs. a control essay). Additionally, frustrated needs led to a biased selection of refugee-hostile over refugee-friendly information and such selection biases, in turn, predicted higher levels of ingroup defense and prejudice toward refugees. The findings imply that host societies’ receptiveness to refugees is influenced by the maintenance of basic psychological needs.
