Prediction of Cognitive Ability With Social Determinants in Children of Low Birth Weight.

Despite strong prevention efforts and advances in neonatal care in recent decades, low birth weight remains a serious public health problem in the United States, and survivors remain at increased risk for lifelong problems including cognitive deficits. Current regional and local strategies for referral often rely on variable thresholds for birth weight and gestational age that may be poor analogues to cognitive risk. Improving early referral criteria offers many benefits, including improved cognitive outcomes for children and improved cost-effectiveness and resource utilization in resource-limited communities. We hypothesized that social determinants measurable at birth or at birth hospital discharge, when combined with birth weight and gestational age, would offer an improvement over birth weight and gestational age alone in predicting cognitive test scores in school-aged children with low birth weight. We conducted a secondary analysis using a birth cohort of children from the Fragile Families and Child Wellbeing Study. We created a panel of maternal, familial, and community-level social determinant indicators from the data and examined associations with cognitive measures assessed at age of 9 years. The final social determinant model was statistically significant and explained 35% of the total variance in composite test scores. The "standard care" model (birth weight and gestational age) only explained 9% of the variance. Assessment of social determinants may offer improvement over traditional referral criteria to identify children most at risk of cognitive deficits after low birth weight.

Working memory capacity and the antisaccade task: A microanalytic-macroanalytic investigation of individual differences in goal activation and maintenance.

The association between working memory capacity (WMC) and the antisaccade task, which requires subjects to move their eyes and attention away from a strong visual cue, supports the claim that WMC is partially an attentional construct (Kane, Bleckley, Conway, & Engle, 2001; Unsworth, Schrock, & Engle, 2004). Specifically, the WMC-antisaccade relation suggests that WMC helps maintain and execute task goals despite interference from habitual actions. Related work has recently shown that mind wandering (McVay & Kane, 2009, 2012a, 2012b) and reaction time (RT) variability (Unsworth, 2015) are also related to WMC and they partially explain WMC's prediction of cognitive abilities. Here, we tested whether mind-wandering propensity and intraindividual RT variation account for WMC's associations with 2 antisaccade-cued choice RT tasks. In addition, we asked whether any influences of WMC, mind wandering, or intraindividual RT variation on antisaccade are moderated by (a) the temporal gap between fixation and the flashing location cue, and (b) whether targets switch sides on consecutive trials. Our quasi-experimental study reexamined a published dataset (Kane et al., 2016) comprising 472 subjects who completed 6 WMC tasks, 5 attentional tasks with mind-wandering probes, 5 tasks from which we measured intraindividual RT variation, and 2 antisaccade tasks with varying fixation-cue gap durations. The WMC-antisaccade association was not accounted for by mind wandering or intraindividual RT variation. WMC's effects on antisaccade performance were greater with longer fixation-to-cue intervals, suggesting that goal activation processes-beyond the ability to control mind wandering and RT variability-are partially responsible for the WMC-antisaccade relation.

Prediction of cognitive abilities at the age of 5 years using developmental follow‐up assessments at the age of 2 and 3 years in very preterm children

This study investigated prediction of separate cognitive abilities at the age of 5 years by cognitive development at the ages of both 2 and 3 years, and the agreement between these measurements, in very preterm children. Preterm children (n=102; 44 males; 58 females) with a gestational age less than 30 weeks and/or birthweight less than 1000g were assessed at the ages of 2 and 3 years using the second edition of the Bayley Scales of Infant Development, the Child Behaviour Checklist, and a neurological examination, and at the age of 5 years using the third edition of the Wechsler Preschool and Primary Scale of Intelligence. Cognitive development at ages 2 and 3 years explained 44% and 57% respectively of full-scale intelligence at the age of 5 years. Adding psychomotor, neurological, and behavioural outcomes to the regression model could not or only marginally improve the prediction; adding perinatal and sociodemographic characteristics to the regression model increased the explained variance to 57% and 64% respectively. These percentages were comparable for verbal intelligence. Processing speed quotient and especially performance intelligence were predicted less accurately. Not all aspects of intelligence are predicted sufficiently by the Mental Development Index at ages 2 and 3 years. Follow-up of very preterm children until at least the age of 5 years is needed to distinguish between different aspects of cognitive development.

The reciprocal relation between children’s attachment representations and their cognitive ability

This study explores reciprocal relations between children’s attachment representations and their cognitive ability. Previous literature has mainly focused on the prediction of cognitive abilities from attachment, rarely on the reverse prediction. This was explored in the current research. Attachment representations were assessed with the Attachment Story Completion Task (Bretherton, Ridgeway, & Cassidy, 1990); the IQ was measured with the WPPSI-III (Wechsler, 2004). Data were collected twice, at a two-year interval, from about 400 preschoolers. Reasoning IQ was found to influence the development of secure attachment representations, while attachment security and disorganization influenced later verbal IQ. The implications of the findings for both clinical and research purposes are discussed in the light of the interactions between cognitive abilities and attachment representations.
