Tummy time without the tears: The impact of parent positioning and play

The American Academy of Pediatrics (AAP) recommends that infants spend supervised time in the prone (tummy) position to foster motor development and prevent cranial deformities. However, infants may not tolerate the position, and consequently, caregivers may avoid placing their infants in the prone position. The AAP recommends that caregivers provide toys or interaction during tummy time. We evaluated the individual and combined effects of a play mat and experimenter interaction on negative vocalizations and head elevation during tummy time—positive effects were limited. Next, we evaluated a parent-led intervention wherein mothers interacted with their infants, using a toy, while lying chest-to-chest. This intervention was associated with a reduction in negative vocalizations and an increase in head elevation for the majority of infants. Additionally, mothers rated the effectiveness of the parent-led intervention more favorably than the experimenter-led intervention, suggesting the effects of the parent-led intervention were also socially valid.     

Exposure to parental and community violence and the relationship to bullying perpetration and victimization among early adolescents: A parallel process growth mixture latent transition analysis

This study examined heterogeneity in parental and community violence exposure during middle school and its association with bullying perpetration and victimization in high school. Youth (N = 1,611) in four Midwestern middle schools participated. Parallel process growth mixture latent transition analysis was used to understand how trajectory profiles of middle school violence exposure was associated with high school bullying profiles. Impulsivity, depression, school belonging, and delinquency were assessed as moderators of the transition probabilities. A three class solution was found for violence exposure: decreasing parental violence/increasing community violence (n = 103; 6.4%), stable high parental violence and low community violence (n = 1,027; 63.7%), and increasing parental violence and stable high community violence (n = 481; 29.8%). Similarly, a three class solution was found for high school bullying: High Bullying Perpetration and High Victimization class (n = 259; 16%), Victimization only (n = 1145; 71%), and low all class (n = 207; 13%). The largest proportion of youth transitioning into the high bullying and high victimization class were from the decreasing parental violence/increasing community violence. Depression, impulsivity, school belonging, and delinquency all had various moderating effects on transition probabilities. Our findings make it apparent that early forms of parental and community violence are associated with aggressive behaviors and experiences with victimization during high school. Prevention and intervention efforts should target individuals who display early and chronic patterns of exposure to violence as these individuals have the greatest risk of later aggressive and victimization in high school.     

Physical aggression toward teachers: Antecedents,behaviors, and consequences

School violence is a significant public health concern that occurs in many forms. Physical aggression can cause serious bodily injury and long-term negative effects, and both teachers and students experience significant rates of physical aggression. There are few studies examining teachers’ experiences of physical aggression. Studies that go beyond prevalence are limited, and we know little about the triggers and consequences that surround these incidents. This qualitative investigation used an antecedent-behavior-consequence (A-B-C) framework to understand how incidents of physical aggression directed toward teachers unfold. The sample included 193 elementary and secondary teachers who completed an anonymous, online survey and described events leading up to and following their experiences with physical aggression. Using conventional content analysis, we identified common antecedents, such as breaking up fights, discipline, and directives, and common consequences, such as student removal, school staff involvement, positive outcomes, and inaction. Further analyses revealed seven common A-B-C patterns among physical aggression incidents that are highlighted and discussed. Utility of the A-B-C framework for teacher-directed violence is described, along with implications for research, practice, and policy. Exploring the context surrounding incidents of physical aggression directed against teachers provides useful information for violence prevention and interventions.     

Expulsion prevention: Framework for the role of infant and early childhood mental health consultation in addressing implicit biases

Young children of color—especially boys—are at disproportionate risk for suspension and expulsion from early care and education settings. Infant and Early Childhood Mental Health Consultation (IECMHC) is an approach associated with lower than expected expulsion rates, but the mechanisms through which it may influence preschool expulsion are unknown. This paper reflects on the parallels between IECMHC and interventions created to reduce implicit bias. Based on interviews with leaders in IECMHC practice, implementation, and evaluation, a theoretical framework was created to articulate how IECMHC is hypothesized to affect expulsion by first reducing the influence of implicit bias on disciplinary decisions. Implications for practice and research are provided.     

Laboratory instruments in the history of psychology

The importance of laboratory instruments as sources for the writing of the history of psychology is stressed, and illustrated through the use of examples where their study has been profitable. Most importantly, the role of the Hipp chronoscope in the reaction-time experiment is discussed, and the importance of various changes introduced into its design by James McKeen Cattell is shown. A photograph, first exhibited by the Department of Psychology of Clark University at the 1893 World's Columbian Exposition in Chicago is included, and further illustrates the importance of these instruments to historians.     

Sleep arrangements and night waking at 6 and 12 months in relation to infants' stress‐induced cortisol responses

The objective of this short‐term longitudinal study was to examine the concurrent and prospective associations of infants' sleep arrangements and night waking with cortisol responses to an inoculation at 6 and 12 months, controlling for several key covariates. To our knowledge, this was the first study to concurrently and prospectively link proximity in sleep arrangements and night waking to physiological stress reactivity. A sample of 92 mother–infant dyads participated in the study when the infants were 6 and 12 months of age, although sample sizes were reduced for some analyses. Both proximal cosleeping arrangements and more frequent night wakings' were associated concurrently with an increased cortisol response to inoculations at both ages. Night waking at 6 months also was associated with a slightly increased cortisol response to inoculation at 12 months. Results aimed at exploring the direction of influence suggested that cosleeping and night waking may influence infant stress physiology rather than the reverse. Adaptive and maladaptive implications of infants' nocturnal experiences and greater stress‐induced cortisol responses are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

Maltreated children's understanding of and emotional reactions to dependency court involvement

Little is known about the extent to which maltreated children understand what is happening during their participation in court proceedings, despite large numbers of children coming into contact with the legal system as victims of maltreatment. In the present study, maltreated 4‐ to 15‐year‐olds were interviewed about their understanding of dependency court on the day of their scheduled court visit. Their feelings about attending their hearings were also assessed, and after their hearing, their understanding of the decisions was examined. Age‐related improvements in children's understanding emerged. Also, children who were more knowledgeable about the legal system were less distressed about attending their hearings, as were younger children who had been in the system a longer time. Finally, a majority of children lacked full or accurate understanding of what actually happened during their hearings. Findings have implications for children's participation in legal proceedings and the development of interventions to facilitate children's legal understanding.

CCTV on trial: Matching video images with the defendant in the dock

The experiments reported in this paper investigated simultaneous identity matching of unfamiliar people physically present in person with moving video images typical of that captured by closed circuit television (CCTV). This simulates the decision faced by a jury in court when the identity of somebody caught on CCTV is disputed. Namely, ‘is the defendant in the dock the person depicted in video’? In Experiment 1, the videos depicted medium‐range views of a number of actor ‘culprits’. Experiment 2 used similar quality images taken a year previously, some of which showed the culprits in disguise. Experiment 3 utilised high‐quality close‐up video images. It was consistently found that in both culprit‐present and culprit‐absent videos and in optimal conditions, matching the identity of a person in video can be highly susceptible to error.

Antidepressants,Psychotherapy or their Combination: Weighing Options for Depression Treatments

Psychotherapy and antidepressant medications are the two preeminent treatment choices for depression. This article puts each of these treatments into perspective by presenting an overview of what is currently known about their effectiveness either singly or in combination. Discussion of placebos, common factors among therapies, relapse rates, depression severity, patient treatment preferences and exaggerations in pharmaceutical advertising provide guidance for clinicians in deciding on the best course of treatment. Overall, research reveals the importance of psychosocial factors, no matter what the mode of treatment, and the need for fostering a collaborative bond between clinicians and their patients. We argue that empirical evidence points to making psychotherapy the initial treatment choice for most cases of depression.
