The strategies children employ to selectively attend to different parts of the face may reflect important developmental changes in facial emotion recognition. Using the Moving Window Technique (MWT), children aged 5-12 years and adults (N = 129) explored faces with a mouse-controlled window in an emotion recognition task. An age-related increase in attention to the left eye emerged at age 11-12 years and reached significance in adulthood. This left-eye bias is consistent with previous eye tracking research and findings of a perceptual bias for the left side of faces. These results suggest that a strategic attentional bias to the left eye begins to emerge at age 11-12 years and is likely established sometime in adolescence.

While much developmental research has focused on the strategies that children employ to recognize faces, less is known about the principles governing the organization of face exemplars in perceptual memory. In this study, we tested a novel, child-friendly paradigm for investigating the organization of face, bird and car exemplars. Children ages 3–4, 5–6, 7–8, 9–10, 11–12 and adults were presented with 50/50 morphs of typical and atypical face, bird and car parent images. Participants were asked to judge whether the 50/50 morph more strongly resembled the typical or the atypical parent image. Young and older children and adults showed a systematic bias to the atypical faces and birds, but no bias toward the atypical cars. Collectively, these findings argue that by the age of 3, children encode and organize faces, birds and cars in a perceptual space that is strikingly similar to that of adults. Category organization for both children and adults follows Krumhansl’s (1978) distance-density principle in which the similarity between two exemplars is jointly determined by their physical appearance and the density of neighboring exemplars in the perceptual space.

Women with problematic substance use are frequently referred to interventions to promote positive parenting. Parenting interventions that attend to the unique risks faced by this population may enhance engagement and outcomes. While reviews of extant parenting interventions in the research literature have been undertaken, no studies have examined parenting interventions being implemented in community practice and the extent to which these are informed by current research. We systematically compared parenting interventions offered in 12 maternal substance use treatment programs in one Canadian province with those described in the research literature ( K = 21). Few parenting interventions were replicated, either within or across the two samples. However, parenting interventions within both samples were largely similar in their objectives. Across both research and community samples, approximately half of the interventions were developed or adapted for a problematic substance use population. Parenting knowledge, psychosocial risk, and maternal emotional regulation were most commonly addressed. Risks pertaining to the impact of drug craving and substance-related changes in neurobiology associted with parenting were less commonly addressed. Findings highlight current strengths and limitations of parenting interventions within research and community settings, with recommendations offered for future research and knowledge translation.
