Extending the simultaneous-sequential paradigm to measure perceptual capacity for features and words

In perception, divided attention refers to conditions in which multiple stimuli are relevant to an observer. To measure the effect of divided attention in terms of perceptual capacity, we introduce an extension of the simultaneous-sequential paradigm. The extension makes predictions for fixed-capacity models as well as for unlimited-capacity models. We apply this paradigm to two example tasks, contrast discrimination and word categorization, and find dramatically different effects of divided attention. Contrast discrimination has unlimited capacity, consistent with independent, parallel processing. Word categorization has a nearly fixed capacity, consistent with either serial processing or fixed-capacity, parallel processing. We argue that these measures of perceptual capacity rely on relatively few assumptions compared to most alternative measures.     

Emerging effortful control in toddlerhood: the role of infant orienting/regulation, maternal effortful control, and maternal time spent in caregiving activities

Latent growth modeling (LGM) was used to examine the contribution of changes in infant orienting/regulation (O/R) to the emergence of toddler effortful control (EC), the contributions of maternal EC to the development of infant O/R and the emergence of toddler EC, the influence of maternal time spent in caregiving activities on toddler EC and the slope of infant O/R, and the contribution of maternal EC to subsequent maternal time spent in caregiving activities. Mothers from 158 families completed a self-report measure of EC when their infants were 4 months of age, a measure of infant O/R when their infants were 4, 6, 8, 10, and 12 months of age, and a measure of toddler EC when their children reached 18 months of age. Information concerning maternal time spent in various interactive caregiving activities was collected when infants were 6 months old. Results indicated higher maternal EC predicted interindividual differences in the intercept (i.e., higher intercepts), but not slope, of infant O/R and that higher maternal EC, higher infant O/R intercept, and higher infant O/R slope contributed to higher toddler EC. Furthermore, higher maternal EC predicted greater maternal time spent in interactive caregiving activities with their infants and greater maternal time in interactive caregiving with infants also contributed to higher toddler EC after controlling for maternal EC. These findings contribute to the understanding of the influence of maternal EC, directly and through caregiving, on toddler EC. Additional implications as they are related to early developing regulatory aspects of temperament are discussed.     

Clinical Utility of Chromosomal Microarray Analysis of DNA from Buccal Cells: Detection of Mosaicism in Three Patients

Mosaic chromosomal abnormalities are relatively common. However, mosaicism may be missed due to multiple factors including failure to recognize clinical indications and order appropriate testing, technical limitations of diagnostic assays, or sampling tissue (s) in which mosaicism is either not present, or present at very low levels. Blood leukocytes have long been the “gold standard” sample for cytogenetic analysis; however, the culturing process for routine chromosome analysis can complicate detection of mosaicism since the normal cell line may have a growth advantage in culture, or may not be present in the cells that produce metaphases (the lymphocytes). Buccal cells are becoming increasingly utilized for clinical analyses and are proving to have many advantages. Buccal swabs allow for simple and noninvasive DNA collection. When coupled with a chromosomal microarray that contains single nucleotide polymorphic probes, analysis of buccal cells can maximize a clinician’s opportunity to detect cytogenetic mosaicism. We present three cases of improved diagnosis of mosaic aberrations using buccal specimens for chromosomal microarray analysis. In each case, the aberration was either undetectable in blood or present at such a low level it likely could have gone undetected. These cases highlight the limitations of certain laboratory methodologies for identifying mosaicism. We also present practice implications for genetic counselors, including clinic workflow changes and counseling approaches based on increasing use of buccal samples.     

ADHD Behaviors and Social Functioning in Preschool Children: The Moderating Role of Emotion Recognition

This study examined the moderating role of emotion recognition on the association between preschoolers’ ADHD behaviors and social functioning outcomes. Sixty preschoolers (48.3% female; M_age?=?3.94, SD_age?=?.56) were recruited from Head Start-affiliated classrooms. Teacher-rated ADHD behaviors and an objective measure of children’s emotion recognition were assessed at the beginning of the school year. Teacher ratings of social functioning outcomes were obtained approximately three months after the start of school. Hierarchical regressions examined the unique and interactive effects of ADHD behaviors and emotion recognition on preschoolers’ social functioning outcomes (i.e., oppositional behaviors, peer behavior problems, and social-emotional school readiness). The interaction between ADHD behaviors and emotion recognition predicted oppositional behaviors, peer behavior problems and social-emotional school readiness such that higher levels of emotion recognition appear to buffer the negative association between ADHD behaviors and adaptive social functioning. Preliminary considerations for interventions aimed at promoting preschoolers’ social functioning are discussed.

A Brief Gratitude Writing Intervention Decreased Stress and Negative Affect During the COVID-19 Pandemic

Exploring ways to mitigate the stress of the COVID-19 pandemic is important for long-term health. Expressive and gratitude-focused writing are effective methods to help individuals process traumatic or stressful events. Gratitude-focused writing may yield additional benefits because it helps individuals appraise events positively. We hypothesized that an online gratitude writing intervention would yield greater benefits than an expressive writing intervention or control group. Participants were randomized to one of three groups and completed assessments one-week and one-month post-intervention. The gratitude writing group maintained gratitude levels and decreased stress and negative affect at one-month post-intervention. The expressive writing group decreased in gratitude and showed no changes in stress or negative affect at one-month post-intervention. The control group decreased in gratitude and negative affect and showed no changes in stress at one-month post-intervention. Gratitude writing may be a better resource for dealing with stress and negative affect than traditional expressive writing methods under extremely stressful situations with uncertain trajectories.

     

Positive affect facilitates social problem solving

We conducted two experiments to test the impact of positive affect on social problem solving. In Experiment 1, participants induced to experience a positive (vs. neutral) affective state generated a greater number of relevant steps to solve fictitious interpersonal problems as well as more effective solutions to the problems. In Experiment 2, participants induced to experience a positive (vs. negative) affective state generated more functional solutions to their own social problems. The positive mood effects observed in Experiment 2 were moderated by dispositional optimism. Our findings have practical implications, as the extent to which individuals are able to generate effective solutions to social problems has far‐reaching consequences with respect to personal adjustment and social functioning.
