Young children’s analogical reasoning across cultures: Similarities and differences

A cross-cultural comparison between U.S. and Hong Kong preschoolers examined factors responsible for young children’s analogical reasoning errors. On a scene analogy task, both groups had adequate prerequisite knowledge of the key relations, were the same age, and showed similar baseline performance, yet Chinese children outperformed U.S. children on more relationally complex problems. Children from both groups were highly susceptible to choosing a perceptual or semantic distractor during reasoning when one was present. Taken together, these similarities and differences suggest that (a) cultural differences can facilitate better knowledge representations by allowing more efficient processing of relationally complex problems and (b) inhibitory control is an important factor in explaining the development of children’s analogical reasoning.     

Guilty,free, and wise: Determinism and psychopathy diminish learning from negative emotions

Emotional experiences can bring about personal growth. For instance, feeling guilty may prompt one to learn from a mistake, and this learning can bring about different and better future behavior. Three studies found that belief in free will facilitated learning from emotional experiences, as inducing participants to disbelieve in free will was associated with reduced learning. Emotional responsiveness, as defined by low psychopathy scores, also facilitated learning from emotional experiences (Studies 2 and 3). The degree of learning associated with emotional experiences was measured by self-rating (Study 1), independent evaluations of lessons learned (Study 2), and whether participants joined a campus recycling program (after being made to feel guilty about an environmental transgression; Study 3).     

Mother–child and father–child mutuality in two contexts: consequences for young children's peer relationships

This study examines the role that context plays in links between relative balance, or mutuality in parent–child interaction and children's social competence. Sixty‐three toddlers and their parents were observed in a laboratory play session and caregiving activity (i.e. eating snack). Mutuality was operationalised as the relative balance in (a) partners' compliance to initiations, and (b) partners' expression of positive emotion. Caregivers rated children's social competence with peers, and children's prosocial and aggressive behaviour with peers was observed in their childcare arrangement. Contextual differences were observed in the manifestation of parent–child mutuality, with both mother–child and father–child dyads displaying higher mutual compliance scores in the play context than in the caregiving context. Father–child dyads also displayed higher levels of shared positive emotion during play than during the caregiving context. There were no differences in a way that parent–child mutuality during play and caregiving was associated with children's social competence with peers. Overall, the results suggest that parent–child mutuality is a quality of parent–child interaction that has consistent links to children's peer competence regardless of the context in which it occurs.

Police endorsement of color‐blind racial beliefs and propensity to interact with youth of color

The beliefs of police, as the point of first contact with the justice system, may help to explain disproportionate minority contact between police and young people. Color‐blind racial beliefs, a form of implicit racism in which racial differences are denied, are more strongly endorsed by police than by laypeople. Using a 2 (youth race) × 3 (offense severity) experimental design, 339 officers participated in an online study examining the influence of youth race, offense severity, and officers' color‐blind racial beliefs on officers' reported likelihood of interacting with young people. Officers with lower levels of color‐blind beliefs reported they would be less likely to interact with Black youth. Additionally, attrition analyses indicated that officers assigned to the Black youth condition were more likely to drop out when asked to complete the measure of color‐blind beliefs. Policy and practice implications are discussed, with a focus on promoting greater discussion of color‐blind ideologies in multicultural trainings for police officers and increasing frank discussions about race and racial issues.     

The effects of transcranial direct current stimulation (tDCS) on multitasking performance and oculometrics

Multitasking is the ability to perform more than one task simultaneously. The need to multitask is common in many industries especially within the military with tasks such as air traffic controllers, cyber defense operators and image analysts. However, as the time on task increases, information throughput can become overwhelming resulting in a performance decrement. Through task prioritizing, the operator is able to maintain performance on specific subtasks in which they selected as high importance while other subtasks experience a decrement. The objective of this study was to evaluate the effects of transcranial direct current stimulation (tDCS) applied to the left dorsolateral prefrontal cortex (ldLPFC) on information processing capabilities to improve individual and overall multitasking performance while performing the multi-attribute task battery (MATB). Two groups of 8 participants each received either 2 mA of anodal or sham tDCS while performing MATB. In addition, eye tracking was implemented to record eye movement patterns. In doing so, we were able to determine how much time the operator allocated to each of the subtasks within MATB and how their task priorities changed as workload demands increased. The findings provided evidence that 2 mA of anodal tDCS during MATB significantly improved overall information throughput compared to the sham group. With respect to the individual subtasks, communication and system monitoring displayed the greatest enhancement with anodal tDCS. Our data suggests that tDCS could be a useful tool to enhance information processing capabilities during a multitasking paradigm resulting in improved processing capabilities and information throughput.     

Dimensions of Pediatric Procedural Distress: Children's Anxiety and Pain During Immunizations

The purpose of this study was to isolate and compare children's procedural anxiety and pain. The study was conducted in a school-based pediatric health clinic with 39 fourth graders receiving 3 injection vaccinations over a 6-month period. Child and nurse ratings and an observational scale assessed anxiety and pain. Results suggest that anxiety and pain are highly correlated, however self-report and an observational measure discriminate between these constructs. Self-report and observational measurement indicated more pediatric pain than anxiety, whereas nurse reports did not indicate differences between children's pain and anxiety.     

Maternal Attributions Related to Compliance with Cystic Fibrosis Treatment

This study examined mothers' attributions related to their children's compliance with various components of medical treatment for cystic fibrosis (CF). Mothers of children with CF were queried regarding adherence rates and reasons for child compliance with chest physiotherapy, inhalation therapy, exercise, medication, and dietary treatments. Maternal attributions for compliance were assessed on the dimensions of parental locus, stability, and controllability. Mothers reported significantly less compliance with diet than with other CF treatments; they also perceived the reasons for compliance with diet and exercise as more external and less under their control. These findings are discussed in relation to parent–child interactions that may be critical to improving treatment adherence, particularly in the context of nutritional interventions.     

A Critical Assessment of Null Hypothesis Significance Testing in Quantitative Communication Research

Null hypothesis significance testing (NHST) is the most widely accepted and frequently used approach to statistical inference in quantitative communication research. NHST, however, is highly controversial, and several serious problems with the approach have been identified. This paper reviews NHST and the controversy surrounding it. Commonly recognized problems include a sensitivity to sample size, the null is usually literally false, unacceptable Type II error rates, and misunderstanding and abuse. Problems associated with the conditional nature of NHST and the failure to distinguish statistical hypotheses from substantive hypotheses are emphasized. Recommended solutions and alternatives are addressed in a companion article.
