Effects of static and motion parallax depth information on perception of size in children and adults

The effects of static and kinetic information for depth on judgments of the relative size of objects placed at different distances was studied in 3- and 7-yr-old children and adults. Subjects viewed either a pair of objects placed on the floor of a textured alley or a projected slide of the identical scene. The presence of motion parallax information for depth was also manipulated. All subjects showed a clear sensitivity to static pictorial depth information in judging objects placed so they projected equal retinal areas. When the retinal size of objects was very different, however, children tended to respond to retinal rather than physical size. Motion parallax information increased responsiveness to depth when a 3-dimensional scene was being viewed, but decreased responsiveness with 2-dimensional projections. The decrease was greater in children than adults.     

The development of procedures for identifying competitive behavior in children

This study identified events in the competitive process that could be employed to discriminate between competition and individual, non-social behaviors. When children competed they overtly sought out information on how they were doing vis-à-vis their fellow competitor. In addition, their performance was a function of some competitive contingency: a reward for surpassing another. The procedures developed in this study were designed to manipulate competitive contingencies while observing their effects on task performance and social comparisons. The investigator could thus infer that competition was present when (1) subjects sought out information on how they were doing, as well as how another was doing on comparable tasks during competitive contingencies, and (2) their task performance was a function of the competitive contingency.     

To prosecute or not to prosecute: Law students' judicial decisions in CSA cases

Child sexual abuse (CSA) investigations are complicated and few cases are prosecuted. The aim of the present study was to investigate judicial decisions in CSA investigations. Seventy‐one law students (42 females, 29 males) read a vignette depicting a CSA investigation, assessed the complainant's and the accused's credibility, and if the case should be prosecuted or not. The participants were assigned to one of four conditions defined by a 2 (evidence: high probative value vs. low probative value) × 2 (complainant demeanour: emotional vs. neutral) factorial design. Females assigned higher credibility to the complainant than did males and males assigned higher credibility to the accused than did females. Emotionality, but not evidential value, affected credibility judgements: Females believed less in the suspect when the child behaved in an emotional manner. Most participants (94.4%) thought that the case should be prosecuted, though only 73.2% believed that prosecution could be corroborated. Corroboration of prosecution was affected by evidential value, but not emotionality. The results indicate that the behavior of alleged crime victims might affect males and females differently, which in turn could lead to biased judicial decisions in CSA investigations.     

Construct validity of the pictorial scale of Perceived Movement Skill Competence

ObjectivesThe Pictorial Scale of Perceived Movement Skill Competence (PMSC) assesses young children's perceptions of movement skill competence: 12 perceived Fundamental Movement skills (FMS; based on the Test of Gross Motor Development 2nd edition TGMD-2) and six Active Play activities (e.g. cycling). The main study purpose was to assess whether children's movement perception scores fit within the imposed constructs of Active Play and FMS by testing the latent structure and construct validity of the PMSC.DesignConstruct validation study.MethodsParticipants were part of the Melbourne Infant Feeding, Activity and Nutrition Trial (InFANT). The latent structure of the PMSC responses was tested through confirmatory factor analysis (CFA) and Bayesian Structural Equation Modeling (BSEM). Internal consistency was conducted using polychoric correlation-based alphas.ResultsThe 303 children (boys 53.1%, n = 161) were aged 4–5 years (M = 4.7, SD = 0.46). The final model had an 18 item 3-factor solution with good fit indices (using CFA and BSEM). Factors were: Active Play (Bike, Board Paddle, Climb, Skate/Blade, Scooter, and Swim), Object Control – Hand Skills (Bounce, Catch, Hit, Throw), and FMS skills with a leg action (Gallop, Hop, Jump, Leap, Run, Step Slide, Kick, Roll). Alpha reliability values were: Active Play (0.78), Object Control-Hand Skills (0.76) and FMS-Dynamic Leg (0.84).ConclusionYoung children can distinguish between movement perceptions. The factors reflect the hypothesized structure in terms of FMS being distinguished from Active Play. Further research should investigate how and if these constructs change in children over time.     

Individual,relationship, and context factors associated with parent support and pressure in organized youth sport

ObjectivesWe examined the association of multiple process, person, and context factors (Bronfenbrenner, 2005) with parents’ involvement (support and pressure) in sport. Specifically, we examined (a) the concordance among self, partner, and child reports of fathers and mothers for key study variables, and (b) prediction of parent support and pressure in youth sport by warmth and conflict in the parent–child relationship, parent positive and negative affect, and mastery and ego dimensions of the coach-created motivational climate.DesignCross-sectional survey.MethodSelf-reports of study variables were collected from athletes (ages 11–13 years) and parents from participating families (final N = 201). Multitrait-multimethod analysis was used to address the first study aim and multivariate multiple regression analysis for the second aim.ResultsValues for concordance among reporters were largely significant and in hypothesized directions, yet were of modest magnitude and suggested low reporter agreement (Cohen's κ range = −.07–.35). Multivariate relationships were significant and were of low to moderate magnitude (R_d range = .04–.22). Canonical loadings showed that warmth, positive affect, and mastery climate positively associate with support, whereas conflict, negative affect, and ego climate positively associate with pressure from fathers and mothers. Conflict and positive affect positively associated with support and pressure in some functions, suggesting complexity in interpretations of parent involvement.ConclusionFindings support the adaptive role of parent-child warmth, positive parent affect, and coach-created mastery motivational climate in youth sport; however, low concordance of reporter perceptions must be considered when pursuing family-related questions in sport.     

Disentangling proactive and reactive aggression in children using self-report

The distinction between proactive and reactive functions of aggression is one of the most common divisions when investigating aggression among children and adolescents. To date, self-report is the least used measurement, despite existing literature supporting the view that the best informant regarding internal processes and motives are children themselves. The main aim of this study was to examine the construct and concurrent validity of a new self-report questionnaire, which aims to disentangle acts of reactive vs. proactive aggression that are most common within the daily lives of children. We examined the self-report measure among 578 children (313 girls, 265 boys, mean age 11 years, range 9–13 years). Most children (90% boys; 85% girls) reported at least one act of aggression over the last four weeks. Furthermore, the outcomes support the two-factor structure (reactive and proactive aggression) and the questionnaire showed good concurrent and discriminant validity with measures for emotional and social functioning. This study validates the use of the self-report instrument for reactive and proactive aggression and demonstrates that children can successfully distinguish between their own motives for reactive and proactive forms of aggressive behaviours.     

Mother‐Stepfather Coparenting in Stepfamilies as Predictor of Child Adjustment

Coparenting between biological parents is a strong predictor of child adjustment. To date, however, little is known about the coparenting dynamics between parent and stepparent in stepfamilies. This study aimed at exploring the links between coparenting in the mother–stepfather dyad and child behavior in stepfamilies compared with the links between mother–father coparenting and child behavior in first‐marriage families. Two modes of coparenting were assessed: overt coparenting, that is, coparental behaviors in the presence of the child, and covert coparenting, that is, the way each parent speaks of the other parent to the child. The sample (N = 80) comprised 48 stepfamilies and 32 first‐marriage families with a child between 7 and 13 years old. Overt coparenting was assessed through direct observation in the standardized situation of the PicNic Game. Covert coparenting and child behavior were assessed through mother‐reported questionnaires. Results showed (a) more covert coparenting behaviors in first‐marriage families, (b) no differences in overt coparenting, (c) more child difficulties reported in stepfamilies, (d) less optimal overt coparenting being linked with more difficulties in children in both family structures, and (e) an interaction effect between family structure and coparenting, showing that overt coparenting is linked with child behavior mainly in stepfamilies.     

Enhancing Capacity for Trauma‐informed Care in Child Welfare: Impact of a Statewide Systems Change Initiative

Youth involved in the child welfare system (CWS) are disproportionally impacted by the negative effects of exposure to trauma. While efforts to develop trauma‐informed CWSs are accelerating, little research is available about the effects of these efforts on system capacity to respond to the needs of youth exposed to trauma. No studies evaluate longer‐term effects of these efforts. In 2011, Connecticut implemented CONCEPT, a multi‐year initiative to enhance capacity of the state's CWS to provide trauma‐informed care. CONCEPT used a multi‐component approach including workforce development, deployment of trauma screening procedures, policy change, improved access to evidence‐based trauma‐focused treatments, and focused evaluation of program effects. Changes in system capacity to deliver trauma‐informed care were assessed using statewide stratified random samples of child welfare staff at three time points (Year 1: N = 223, Year 3: N = 231, Year 5: N = 188). Significant improvements across nearly all child welfare domains were observed during the first 3 years of implementation, demonstrating system‐wide improvements in capacity to provide trauma‐informed care. These gains were maintained through the final year of implementation, with continued improvements in ratings of collaboration between child welfare and behavioral health settings on trauma‐related issues observed. Responses documented familiarity with and involvement in many of the CONCEPT activities and initiatives. Staff reported greater familiarity with efforts to increase access to specific evidence‐based services (e.g., TF‐CBT) or to enhance trauma‐related policy and practice guidelines, but less familiarity with efforts to implement new practices (e.g., trauma screening) in various sectors. Staff also reflected on the contribution of these components to enhance system capacity for trauma‐informed care.     

Dyadic synchrony among young Latina mothers and their toddlers: The role of maternal and child behavior

Synchronous interactions are an important indicator of parent-child relationship quality with positive implications for child development. Latina adolescent mothers face several demographic challenges that place them at risk for less synchronous interactions. To identify factors that may facilitate more optimal parent-child relationships in this population, our study examined maternal sensitivity and children’s behavioral styles as joint predictors of dyadic synchrony among young Latina mothers and their toddlers. Mother-toddler dyads (N = 170) were observed interacting across different tasks, and toddlers’ behavior was observed during the administration of a developmental test. Results of multivariate regressions revealed additive effects of maternal sensitivity and child behavioral styles (i.e., dysregulation and positive attentional control). Maternal sensitivity related to higher dyadic synchrony for the entire sample. Positive attentional control was related to higher dyadic synchrony for mother-daughter dyads only. Although no gender differences in dyadic synchrony or the behavior style variables emerged, the relative contribution of maternal and child factors differed by child gender, suggesting that mothers may have responded differently to similar behavior and affect displayed by boys and girls. The findings provide insights regarding factors that contribute to dyadic synchrony in this understudied population and emphasize the need to consider child gender when studying parent-child interactions in young Latina families.
