Conflict monitoring and anterior cingulate cortex: an update

One hypothesis concerning the human dorsal anterior cingulate cortex (ACC) is that it functions, in part, to signal the occurrence of conflicts in information processing, thereby triggering compensatory adjustments in cognitive control. Since this idea was first proposed, a great deal of relevant empirical evidence has accrued. This evidence has largely corroborated the conflict-monitoring hypothesis, and some very recent work has provided striking new support for the theory. At the same time, other findings have posed specific challenges, especially concerning the way the theory addresses the processing of errors. Recent research has also begun to shed light on the larger function of the ACC, suggesting some new possibilities concerning how conflict monitoring might fit into the cingulate's overall role in cognition and action.     

A case for a duty to feed the hungry: GM plants and the third world

This article is concerned with a discussion of the plausibility of the claim that GM technology has the potential to provide the hungry with sufficient food for subsistence. Following a brief outline of the potential applications of GM in this context, a history of the green revolution and its impact will be discussed in relation to the current developing world agriculture situation. Following a contemporary analysis of malnutrition, the claim that GM technology has the potential to provide the hungry with sufficient nourishment will be discussed within the domain of moral philosophy to determine whether there exists a moral obligation to pursue this end if and only if the technology proves to be relatively safe and effective. By using Peter Singer's duty of moral rescue, I argue that we have a moral duty to assist the third world through the distribution of such GM plants. I conclude the paper by demonstrating that my argument can be supported by applying a version of the Precautionary Principle on the grounds that doing nothing might be worse for the current situation.     

Impact of Traumatic Life Events in a Community Sample of Toddlers

Toddlers may be at particularly high risk for a number of psychiatric, developmental and neurobiological consequences in the aftermath of trauma. The social and emotional impact of potentially traumatic life events experienced between 6 and 36-months of age was assessed in an epidemiological birth cohort of 18- to 36-month-olds from the Greater New Haven Area. Event-exposed toddlers evidenced greater symptom severity on the ITSEA Internalizing, Externalizing, Dysregulation, Atypical and Maladaptive scales, as well on the CBCL Internalizing and Externalizing scales than those not exposed. Approximately one-fifth of event-exposed toddlers were reported by their parents to have experienced a dramatic change in functioning following the event, and were described as experiencing higher levels of symptoms consistent with Post-Traumatic Stress Disorder (PTSD), namely re-experiencing and arousal, than exposed toddlers whose parents did not report a change in their functioning. Implications for clinicians and child care providers working with toddlers and their parents are discussed.     

Preliminary acceptability and psychometrics of the infant–toddler social and emotional assessment (ITSEA): A new adult-report questionnaire

The preliminary acceptability, internal consistency, test–retest reliability, and validity of the Infant–Toddler Social and Emotional Assessment (ITSEA), a parent-report questionnaire concerning social-emotional problems and competencies, were examined in a sociodemographically diverse pediatric sample of 214 parents of 12- to 36-month-olds. Results supported the ITSEA's acceptability and preliminary internal consistency, test–retest reliability, and validity. Most parents had a positive response to the ITSEA, found the questions easy to understand, and would consider recommending it to a friend. Confirmatory factor analyses supported 16 conceptually hypothesized problem and competence scales. Most scales had strong internal consistency, good to excellent 2-week test–retest reliability, and moderate 1-year test–retest reliability. Significant correlations among ITSEA scales and parent reports of child temperament and problem behaviors supported the ITSEA's validity. Psychometric findings are viewed as preliminary due to the relatively small sample size. Parents reported greater competence and more maladaptive behaviors in older children than younger children. Consistent with observational studies, boys lagged behind girls in certain parent-reported competencies, including empathy, compliance, prosocial peer interactions, and emotional awareness. Parent reports yielded empirically coherent problem and competence scales and domains, suggesting the early emergence of parental perceptions of organized and differentiated clusters of social-emotional behaviors.
