Applying gaze-contingent training within community settings to infants from diverse SES backgrounds

Ballieux, H., Wass, S., Tomalski, P., Kushnerenko, E., Karmiloff-Smith, A., Johnson, M., & Moore, D. 2016. Journal of Applied Developmental Psychology

Even in infancy children from low-SES backgrounds differ in frontal cortex functioning and, by the start of pre-school, they frequently show poor performance on executive functions including attention control. These differences may causally mediate later difficulties in academic learning. Here, we present a study to assess the feasibility of using computerized paradigms to train attention control in infants, delivered weekly over five sessions in early intervention centres for low-SES families. Thirty-three 12-month-old infants were recruited, of whom 23 completed the training. Our results showed the feasibility of repeat-visit cognitive training within community settings. Training-related improvements were found, relative to active controls, on tasks assessing visual sustained attention, saccadic reaction time, and rule learning, whereas trend improvements were found on assessments of short-term memory. No significant improvements were found in task switching. These results warrant further investigation into the potential of this method for targeting ‘at-risk’ infants in community settings.

Allostasis and metastasis: the yin and yang of childhood self-regulation

Wass, S. 2021. PsyArXiv

Most research has studied self-regulation by presenting experimenter-controlled test stimuliand measuring change between a baseline period and the stimulus. But in the real world weare not passive recipients of discrete chunks of external stimulation, to which we in turnrespond; rather, the real world is continuous and we self-regulate by adaptively selectingwhich aspects of the social environment that we attend to from one moment to the next. Here,we contrast two dynamic processes that guide this process – the ‘yin’ and ‘yang’ of self-regulation. First, allostasis, through which we dynamically compensate for change tomaintain homeostasis. This involves upregulating in some situations and downregulating inothers. And second, metastasis, the dynamical principle underling dysregulation. Throughmetastasis, small initial fluctuations can become progressively amplified over time. Wecontrast these processes at the individual level (i.e. by examining moment-to-moment changein one child, considered independently) and also at the inter-personal level (i.e. by examiningchange across a dyad, such as a parent-child dyad). Finally, we discuss practical implicationsof this approach in improving the self-regulation of emotion and cognition, in typicaldevelopment and psychopathology.

Infant effortful control mediates relations between nondirective parenting and internalising-related child behaviours in an autism-enriched infant cohort

Smith, C., Jones, E., Wass, S., Pasco, G., Johnson, M., Charman, & Wan, M. 2021. Journal of Autism and Developmental Disorders

Internalising problems are common within Autism Spectrum Disorder (ASD); early intervention to support those with emerging signs may be warranted. One promising signal lies in how individual differences in temperament are shaped by parenting. Our longitudinal study of infants with and without an older sibling with ASD investigated how parenting associates with infant behavioural inhibition (8–14 months) and later effortful control (24 months) in relation to 3-year internalising symptoms. Mediation analyses suggest nondirective parenting (8 months) was related to fewer internalising problems through an increase in effortful control. Parenting did not moderate the stable predictive relation of behavioural inhibition on later internalising. We discuss the potential for parenting to strengthen protective factors against internalising in infants from an ASD-enriched cohort.
