Does late preterm birth impact trunk control and early reaching behavior?

The aims of the study were to 1) verify the level of trunk control longitudinally and reaching behavior while sitting in two positions in late preterm (LPT) and full-term (FT) infants, 2) determine whether the level of trunk control relates to reaching outcomes. Twenty LPT infants and 36 infants born FT were assessed via three in-lab visits: at 6, 7, and 8 months. At each visit, the Segmental Assessment of Trunk Control (SATCo) and reaching assessment were performed, where the infants were positioned sitting in the ring and at 90° of flexion of hips, knees, and ankles. Accurate manual support to the trunk was provided in each visit. LPT infants presented a lower level of trunk control over time. LPT infants presented a higher percentage of unimanual reaches and successful grasping at 7 months' visit, and a higher number of reaches at 8 months' visit compared to FT infants. The sitting positions did not influence reaching performance. The level of trunk control relates to functional reaching strategies only in FT infants. This study might provide insights for clinicians for understanding the level of trunk control, the importance of reaching behaviors for exploration, and considering these behaviors as strategies for intervention.     

Role of maternal affect and regulatory strategies in toddlers’ emotion and behavior regulation

Using a moment-to-moment multilevel approach, we examined the relative effectiveness of (a) toddlers’ lagged (i.e., previous-interval) regulatory strategies and toddlers’ lagged expression of negative emotion, as moderated by maternal affect, and (b) maternal lagged regulatory strategies, on toddlers’ current-interval (1) expression of negative emotion, and, (2) ability to delay gratification during a wait task. Two-level random coefficient models, with twelve repeated-measurement occasions (10 s-intervals) of observed behaviors (N = 1571) nested within 134 mother-toddler dyads from low-income families (67 girls; M_age = 25.77 months, SD_age = 1.60) were examined. Cross-level interactions revealed that maternal positive affect buffered severity of toddlers’ expression of negative emotion between lagged and current-intervals, while maternal negative affect disrupted toddlers’ effective utilization of lagged regulatory strategies on current-interval expression of negative emotion. However, regardless of maternal affect, toddlers who displayed higher expression of negative emotion and utilized more regulatory strategies in lagged-intervals displayed greater delay of gratification in current-intervals. Also, as mothers displayed greater minimization of toddlers' emotional distress, higher physical restraint, and used fewer distractions, toddlers displayed more intense expression of negative emotion in subsequent intervals. Similarly, as mothers used higher physical restraint and fewer distractions, toddlers were less able to wait in subsequent intervals. Results illustrate the disruptive roles of maternal negative affect and unsupportive regulatory strategies on toddlers' emotion and behavior regulation. Together, these findings point to targeting maternal positive affect in combination with supportive regulatory strategies to promote toddlers’ transition from external- to internal-regulation.     

Early socialization of prosocial behavior: Patterns in parents’ encouragement of toddlers’ helping in an everyday household task

Patterns in parents’ socialization of prosocial behavior in 18- and 24-month-olds (n = 46) were investigated during an everyday household chore that parents were asked to complete with their toddlers. Two socialization approaches were distinguished, one focused on specific requests for concrete actions needed to complete an immediate, concrete goal (“action-oriented”), and a second focused on the more abstract needs and emotions of the parent and the child's role as a helper (“need-oriented’). Parents were equally active at both ages in trying to elicit children's help but used different strategies with younger and older toddlers. With 18-month-olds they used more action-oriented approaches, whereas with 24-month-olds they increased their use of need-oriented approaches. They also regulated the attention of younger toddlers more, and more often socially approved older toddlers’ helping. Thus, how parents prompt, support, and encourage prosocial behavior changes over the second year from utilizing primarily concrete, goal-directed requests in the service of the immediate task, to increasingly emphasizing more abstract needs and emotions of the recipient and the child's role as a helper.     

Intrafamilial physical victimization and externalizing behavior problems: Who remain the ‘forgotten’ children?

Over the past few decades, researchers have documented positive associations between direct child maltreatment and exposure to interpersonal violence (including intimate partner violence, community violence, school violence, and media violence) and children's externalizing behavior problems. However, current family violence literature largely ignores the effects of child abuse on other children in the family. A handful of studies have focused on exposure to child abuse and documented the behavioral effects on siblings, and these studies lend support for broadening scholarship focused on this type of family violence. This article presents empirical research and theories that focus on the relationships between child physical abuse and exposure to intimate partner violence and children's externalizing behavior problems. Using this literature as a foundation, an argument is made for the need to focus on children's exposure to child physical abuse. This article presents information from the few studies that have focused on children who were exposed to the physical abuse of a sibling and offers theoretical frameworks, including social learning theory and psychological proximity, as a foundation for future research. The article concludes with a discussion of services that may be necessary for children who have been exposed to the physical abuse of a sibling, including services focused on safety and mental health.     

Negative body image and disordered eating behavior in children and adolescents: what places youth at risk and how can these problems be prevented?

In this review, we examine the prevalence of negative body image and disordered eating behaviors (i.e., excessive dieting, binge eating, inappropriate weight loss techniques) in children and adolescents. We also explore correlates and predictors of the development of these problems, including individual, familial, and social factors, as well as discuss factors that may serve a protective function. In addition, we critically evaluate the psychoeducational programs that have been developed to prevent the onset of these problems and reduce the severity of symptoms in children and adolescents. Moreover, we suggest several possible strategies for how such prevention programs can be modified to enhance their efficacy. Finally, likely moderator and mediator variables of the effectiveness of such programs are proposed.     

Swedish youth football players’ attitudes towards moral decision in sport as predicted by the parent-initiated motivational climate

ObjectivesThe purpose of this study was to examine associations between late adolescent football players’ perceptions of the motivational climate – as initiated by mothers and fathers – and attitudes towards moral decision making in sports.DesignCross-sectional.MethodsParticipants were 213 Swedish football players (144 males, 67 females) aged 16–19 years who completed measures assessing perceived parent-initiated motivational climate (i.e., success-without-effort climate [SWEC]; worry conducive climate [WCC]; and learning/enjoyment climate [LEC]) and attitudes towards moral decision-making in sport (i.e., acceptance of cheating [AOC]; acceptance of gamesmanship [AOG] and keeping winning in proportion [KWIP]).ResultsCanonical correlations demonstrated moderate positive relations between parent-initiated − both mother and father − performance climates (WCC and SWEC) and AOC and AOG. Moreover, the relationship between mother and father-initiated learning/enjoyment climate (LEC) were shown to be moderately and positively associated with the prosocial attitude dimension of KWIP. Results also showed that a mother-initiated LEC and a mother-initiated SWEC were stronger predictors of the criterion variables (AOC, AOG, and KWIP) than equivalent father-initiated climate dimensions.ConclusionsThe results highlight the importance of considering the relationship between parent-initiated climates − especially initiated by mothers − and the development of moral decision-making among youth football players.     

School social climate and teachers’ perceptions of classroom behavior problems: a 10 year longitudinal and multilevel study

Using longitudinal and cross-sectional data, the present research sought to identify school social climate predictors of teachers’ perceptions of classroom behavior problems. The social climate and classroom behavior in 107 public and private French speaking Canadian high schools was evaluated by 1399 teachers. The present analysis is unique in its ability to control for school differences in the enrollment of students with a history of problem behavior. As hypothesized, between-school variation in the proportion of students with histories of disruptive problems predicted high school classroom behavior problems. Moreover, when controlling for these between-school differences, concurrently measured school-level variables (type of school, location of school, and academic emphasis) are found to be significant predictors of classroom behavior problems. The theoretical and practical implications of the present findings are examined and recommendations are made for future research.     

Research on parking choice behavior of shared autonomous vehicle services by measuring users’ intention of usage

Shared autonomous vehicles (SAVs) are one of the important development directions of smart and green transportation. However, relevant researches are not sufficient at present. The factors influencing the intention to use SAVs and their parking choice behaviors need to be further analyzed. First, in order to better explain, predict, and improve travelers’ intention to use SAVs, the conceptual framework based on technology acceptance model was developed to establish the relationships between the travelers’ intention to use SAVs, social influence of SAVs, attitude toward behavior of SAVs, perceived risk of SAVs, perceived usefulness of SAVs and perceived ease of these use. Then structural equation model (SEM) was established to analyze the relationship between various variables. The results show that the perceived usefulness, behavior attitude, social influence, perceived ease of use, and perceived risk are the main factors that determine the intention to use SAVs. Through the test of direct effect, indirect effect, and total effect in the model, it is found that perceived usefulness has the largest total impact on intention to use SAVs, with a standardized coefficient of 0.765, followed by behavior attitude (0.732), social influence (0.597), perceived ease of use (0.462) and perceived risk of SAVs (−0.452). In addition, through the study of observed indicator variables ATB2 and BI3, it is found that perceived usefulness, perceived ease of use, social influence, perceived risk, attitude toward behavior, and behavior intention all have an impact on parking behavior. In order to study the specific influencing factors of parking choice behavior, a multinomial logit (MNL) model was established to analyze the relationships between travelers’ parking choice behaviors and the influential factors, which include travelers’ individual characteristics, travel attributes, and parking modes’ attributes by extracting from a questionnaire. The results show that the travel time, travel fees, parking charge, cruising fees, parking time and traffic emission are the main factors that determine travelers’ choices of parking. This paper provides advice for operators of SAVs.     

Examining pathways linking maternal depressive symptoms in infancy to children’s behavior problems: The role of maternal unresponsiveness and negative behaviors

The extent to which maternal depressive symptoms in the first 6 months of life is linked with internalizing and externalizing behaviors in childhood through specific insensitive maternal behaviors (unresponsive and overtly negative behaviors) was examined in a sample of 259 mother-infant dyads. In addition, the extent to which these paths were moderated by infant negative emotionality was also examined. Maternal depressive symptoms were assessed prenatally and when infants were 6 months and 2 years old. Maternal unresponsive and overtly negative behaviors and infant negative emotionality were observed when infants were 6 months old. Mothers reported on infant’s internalizing and externalizing behaviors when infants were 2 years old. Maternal depressive symptoms were directly associated with higher internalizing behaviors; this path was not mediated by maternal behaviors. Depressive symptoms were unrelated to externalizing symptoms. Infant negative emotionality did not moderate these effects, but was related positively to overtly negative maternal behaviors, and temperament interacted with maternal depressive symptoms to predict unresponsive maternal behaviors. Results suggest that early maternal depressive symptoms, infant negative emotionality, and negative maternal behavior pose risk for infants’ later internalizing behaviors, but the proposed moderated mediation model was not supported.     

‘Fighting’ for survival: A systematic review of physically violent behavior perpetrated and experienced by homeless young people

ObjectivesThis systematic review appraises published studies reporting associations between homelessness, perpetration of physically violent behavior and experience of victimization due to others' physically violent behavior, among young people.MethodsA comprehensive systematic search of psychology, sociology, and health electronic databases, including PsycInfo and SocIndex was conducted. Search terms examined (a) homeless youth, (b) perpetration of physically violent behavior, and (c) experience of victimization due to others' physically violent behavior.ResultsTwenty-nine studies met the inclusion criteria. Findings showed homeless youth report engaging in physically violent behavior including assault, physical fights, and robbery, and commonly describe victimization experiences such as being physically assaulted, threatened with weapons, and robbed. Rates of perpetration of physically violent behavior and experiences of victimization were inconsistent across reviewed studies. It is unclear whether homelessness is a predictor of the perpetration of physically violent behavior and/or victimization. Findings suggest that perpetration of, and being victimized by others' physically violent behavior, may vary for sub-groups of homeless youth.ConclusionsFurther research embedded within theoretical perspectives that consider the influence of situational antecedents is warranted to examine whether homelessness is predictive of engagement in physically violent behavior and the experience of victimization due to others' physically violent behavior.     

“Should I or shouldn’t I?” Imitation of undesired versus allowed actions from peer and adult models by 18- and 24-month-old toddlers

Imitation is a common way of acquiring novel behaviors in toddlers. However, little is known about toddlers’ imitation of undesired actions. Here we investigated 18- and 24-month-olds’ (N = 110) imitation of undesired and allowed actions from televised peer and adult models. Permissiveness of the demonstrated actions was indicated by the experimenter’s response to their execution (angry or neutral). Analyses revealed that toddlers’ imitation scores were higher after demonstrations of allowed versus undesired actions, regardless of the age of the model. In agreement with prior research, these results suggest that third-party reactions to a model’s actions can be a powerful cue for toddlers to engage in or refrain from imitation. In the context of the present study, third-party reactions were more influential on imitation than the model’s age. Considering the relative influence of different social cues for imitation can help to gain a fuller understanding of early observational learning.
