Same Behaviors, Different Outcomes: Mothers' and Fathers' Observed Challenging Behaviors Measured Using a New Coding System Relate Differentially to Children's Social-Emotional Development.

This study used a newly developed coding system for measuring the quality of parenting behavior to examine associations with children's social-emotional development. The Risky Interaction Support and Challenge Scale (RISCS) measures the extent to which parents engage in behaviors that present physical and regulatory challenges to children, as well as parents' tendency to allow children to pursue action goals autonomously. These behaviors were observed while parents (n = 57 fathers; n = 55 mothers; n = 50 pairs) interacted with their 1-year-olds who played on a structure that included a slide, a small climbing wall, and a tunnel. Trained raters reliably used the RISCS to measure several dimensions of parent behaviors related to children's exploration, and all but one of the dimensions captured adequate variability in parent behavior. Although mothers and fathers did not differ in any of the dimensions, the associations between parent behavior and children's social-emotional development did not overlap. Fathers who engaged in greater autonomy allowance and lower overprotection had toddlers with lower levels of internalizing behavior, whereas mothers who challenged children's regulatory competence had toddlers with lower levels of externalizing behavior and greater competence. We discuss the implications of the findings for the literature on attachment theory and father-child relationships.

Enhancing student retention of prerequisite knowledge through pre-class activities and in-class reinforcement.

To foster the connection between biochemistry and the supporting prerequisite concepts, a collection of activities that explicitly link general and organic chemistry concepts to biochemistry ideas was written and either assigned as pre-class work or as recitation activities. We assessed student learning gains after using these activities alone, or in combination with regularly-integrated clicker and discussion questions. Learning gains were determined from student performance on pre- and post-tests covering key prerequisite concepts, biochemistry course exams, and student self-evaluation. Long-term retention of the material was assessed using a comprehensive exam given to a subset of the students. Our results show that using the pre-class exercises in combination with integrative questions was effective at improving student performance in both the short and long term. Similar results were obtained at both a large research institution with large class enrollments and at a private liberal arts college with moderate enrollments. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):97-104, 2017.

The Children's Social Understanding Scale: construction and validation of a parent-report measure for assessing individual differences in children's theories of mind.

Children's theory of mind (ToM) is typically measured with laboratory assessments of performance. Although these measures have generated a wealth of informative data concerning developmental progressions in ToM, they may be less useful as the sole source of information about individual differences in ToM and their relation to other facets of development. In the current research, we aimed to expand the repertoire of methods available for measuring ToM by developing and validating a parent-report ToM measure: the Children's Social Understanding Scale (CSUS). We present 3 studies assessing the psychometric properties of the CSUS. Study 1 describes item analysis, internal consistency, test-retest reliability, and relation of the scale to children's performance on laboratory ToM tasks. Study 2 presents cross-validation data for the scale in a different sample of preschool children with a different set of ToM tasks. Study 3 presents further validation data for the scale with a slightly older age group and a more advanced ToM task, while controlling for several other relevant cognitive abilities. The findings indicate that the CSUS is a reliable and valid measure of individual differences in children's ToM that may be of great value as a complement to standard ToM tasks in many different research contexts.

Youth with autism spectrum disorder comprehend lexicalized and novel primary conceptual metaphors.

Individuals with autism spectrum disorder (ASD) have difficulty comprehending metaphors. However, no study to date has examined whether or not they understand conceptual metaphors (i.e. mappings between conceptual structures), which could be the building blocks of metaphoric thinking and understanding. We investigated whether 13 participants with ASD (age 7;03-22;03) and 13 age-matched typically developing (TD) controls could comprehend lexicalized conceptual metaphors (e.g., Susan is a warm person) and novel ones (e.g., Susan is a toasty person). Individuals with ASD performed at greater than chance levels on both metaphor types, although their performance was lower than TD participants. We discuss the theoretical relevance of these findings and educational implications.

Infants recognize similar goals across dissimilar actions involving object manipulation.

We investigated infants' ability to recognize the similarity between observed and implied goals when actions differed in surface-level motion details. In two experiments, 10- to 12-month-olds were habituated to an actor manipulating an object and then shown test actions in which the actor contacted the object with a novel hand configuration that implied a goal either similar or dissimilar to the habituation event. Infants in both experiments looked significantly longer at test actions depicting a novel implied goal, suggesting that infants glossed over some surface-level motion details and compared implied goals.
