Does the Amount of Participation in Afterschool Programs Relate to Developmental Outcomes? A Review of the Literature

Contrary to the findings from previous reviews we found little support for the general notion that greater amounts of participation in afterschool programs was related to academic, behavioral, or socio-emotional outcomes. However, some relationships did emerge depending on how participation was conceptualized and measured, and the methodology used to assess the relationship between participation and outcomes. For example, some benefits occurred when participants with high levels of participation were compared to non-participants, not when they were compared to other program participants. Several suggestions are offered to improve future research on the relationship between aspects of participation and developmental outcomes.     

Developmental Trajectories of Boys’ and Girls’ Delinquency: Sex Differences and Links to Later Adolescent Outcomes

This study examined gender differences in trajectories of delinquent behaviors over a 6-year period in adolescence and differential outcomes of these diverse developmental pathways. Participants were 754 children who were part of a longitudinal study of the development of early starting conduct problems. Four trajectory patterns were identified across grades 7–12: increasing, desisting, chronic, and nonproblem groups. Although the proportion of boys and girls varied across the pathways, both genders were represented on these trajectories. Boys were more represented on the chronic and desisting trajectories; girls were more represented in the nonproblem group. However, the proportion of boys and girls was similar in the increasing trajectory. Trajectory membership significantly predicted age 19 outcomes for partner violence, risky sexual behavior and depression, and the risk conferred on these negative adjustment outcomes did not vary by gender. The overall pattern was characterized by poor outcomes at age 19 for youth in both the chronic and the increasing trajectories. The major conclusion is that, other than base rate differences, developmental patterns and outcomes for girls mimic those previously found for boys.     

Understanding the “ghosts in the nursery” of pregnant women experiencing domestic violence: Prenatal maternal representations and histories of childhood maltreatment

Selma Fraiberg and colleagues (1975) conceptualized the “ghosts in the nursery” as experiences from a mother's past that influenced her ability to form a warm and attuned relationship with her child. Contemporary infant mental health interventions often ask the mother to reflect on her own history of attachment relationships to gain insight into as well as to strengthen her developing relationship with her child. This study investigated the association between a mother's history of childhood maltreatment (CM) and her subsequent prenatal maternal representation during the third trimester of pregnancy. Controlling for domestic violence (DV), distorted prenatal representations were associated with higher rates of self‐reported childhood physical neglect. In addition, DV moderated the relationship between representations and CM, such that women who were exposed to DV during pregnancy and had distorted prenatal representations were least likely to report childhood physical and sexual abuse. Implications are discussed in relation to infant mental health interventions which rely on a parent's ability to psychologically access and reflect on childhood histories to more sensitively parent her own child.     

A Dual-Process Discrete-Time Survival Analysis Model: Application to the Gateway Drug Hypothesis

The gateway drug model is a popular conceptualization of a progression most substance users are hypothesized to follow as they try different legal and illegal drugs. Most forms of the gateway hypothesis are that “softer” drugs lead to “harder,” illicit drugs. However, the gateway hypothesis has been notably difficult to directly test—that is, to test as competing hypotheses in a single model that licit drug use might lead to illicit drug use or the reverse. This article presents a novel statistical technique, dual-process discrete-time survival analysis, which enables this comparison. This method uses mixture-modeling software to estimate 2 concurrent time-to-event processes and their effects on each other. Using this method, support for the gateway hypothesis in the National Longitudinal Survey of Youth, 1997, was weak. However, this article was not designed as a strong test of causal direction but more as a technical demonstration and suffered from certain technological limitations. Both these limitations and future directions are discussed.     

Basal ganglia, dopamine and temporal processing: performance on three timing tasks on and off medication in Parkinson's disease

A pervasive hypothesis in the timing literature is that temporal processing in the milliseconds and seconds range engages the basal ganglia and is modulated by dopamine. This hypothesis was investigated by testing 12 patients with Parkinson's disease (PD), both 'on' and 'off' dopaminergic medication, and 20 healthy controls on three timing tasks. In a seconds range (30-120 s) time production task, patients tested 'on' medication showed a significantly different accuracy profile compared to controls and when tested 'off' medication. However, no group or on vs off medication differences in accuracy were found on a time reproduction task and a warned reaction time task requiring temporal processing within the 250-2000 ms range. Variability was measured using the coefficient of variation, with the performance of the patient group on the time reproduction task violating the scalar property, suggesting atypical temporal processing mechanisms. The data suggest that the integrity of the basal ganglia is necessary for 'typical' time production in the seconds range as well as for time reproduction at shorter intervals. Exploratory factor analysis suggested that the time production task uses neural mechanisms distinct from those used in the other two timing tasks. The dissociation of the effects of dopaminergic medication and nature of task on performance in PD raises interesting questions about the pharmacological mediation and task-specificity of deficits in temporal processing.     

“Weathering the storm:” Mothers’ and fathers’ experiences of parenting a preterm infant

Parenting preterm infants is a unique experience distinct from parenting full-term infants, characterized by a delayed transition to parenthood and limited caregiving opportunities. This study explored mothers’ and fathers’ lived experiences of parenting during infancy in the context of preterm birth. Semistructured qualitative interviews were conducted with 13 parents (6 fathers, 7 mothers) of preterm infants. Data were analyzed using interpretative phenomenological analysis. Four superordinate themes emerged: (a) An unnatural disaster: The traumatic nature of preterm birth, (b) The immediate aftermath: Disconnected and displaced, (c) Breaking the ice: Moving from frozen to melted, and (d) Aftershocks: Transitioning home. Both parents experienced preterm birth as traumatic. Similarities and differences in mothers’ and fathers’ experiences were identified. Preterm birth posed challenges for nurturant and social caregiving and resulted in anxiety, hypervigilance, and overprotective parenting behavior. The results highlight the need for trauma-informed care and further research developing and testing empirically based interventions.     

Cues to deception

Do people behave differently when they are lying compared with when they are telling the truth? The combined results of 1,338 estimates of 158 cues to deception are reported. Results show that in some ways, liars are less forthcoming than truth tellers, and they tell less compelling tales. They also make a more negative impression and are more tense. Their stories include fewer ordinary imperfections and unusual contents. However, many behaviors showed no discernible links, or only weak links, to deceit. Cues to deception were more pronounced when people were motivated to succeed, especially when the motivations were identity relevant rather than monetary or material. Cues to deception were also stronger when lies were about transgressions.     

The development of bodily self‐consciousness: changing responses to the Full Body Illusion in childhood

The present work investigates the development of bodily self‐consciousness and its relation to multisensory bodily information, by measuring for the first time the development of responses to the full body illusion in childhood. We tested three age groups of children: 6‐ to 7‐year‐olds (n = 28); 8‐ to 9‐year‐olds (n = 21); 10‐ to 11‐year‐olds (n = 19), and a group of adults (n = 31). Each participant wore a head‐mounted display (HMD) which displayed a view from a video camera positioned 2 metres behind their own back. Thus, they could view a virtual body from behind. We manipulated visuo‐tactile synchrony by showing the participants a view of their virtual back being stroked with a stick at the same time and same place as their real back (synchronous condition), or at different times and places (asynchronous condition). After each period of stroking, we measured three aspects of bodily self‐consciousness: drift in perceived self‐location, self‐identification with the virtual body, and touch referral to the virtual body. Results show that self‐identification with the virtual body was significantly stronger in the synchronous condition than in the asynchronous condition even in the youngest group tested; however, the size of this effect increased with age. Touch referral to the virtual body was greater in the synchronous condition than in the asynchronous condition only for 10‐ to 11‐year‐olds and adults. Drift in perceived self‐location was greater in the synchronous condition than in the asynchronous condition only for adults. Thus, the youngest age tested can self‐identify with a virtual body, but the links between multisensory signals and bodily self‐consciousness develop significantly across childhood. This suggests a long period of development of the bodily self and exciting potential for the use of virtual reality technologies with children.
