AbstractAlmost six decades of research have consistently demonstrated that intergroup contact is one of the most powerful ways of improving intergroup attitudes. At least two important limitations, however, still compel researchers to continue work in this area: the issue of long-term effects of contact, and the processes underlying such effects. This report makes a theoretical and empirical contribution with regard to these two aspects introducing a new mediator of the effects of contact: verification of qualities of typical ingroup members that may or may not characterize individual group members (e.g. verification of ingroup identities). One hundred and forty-two high school students participated in a two-wave longitudinal study with 12 weeks’ lag in Spain. Cross-sectional and longitudinal mediational analyses using multiple imputation data showed that intergroup contact improves general outgroup evaluation through increasing verification of ingroup identities. This research demonstrates the relevance of considering verification of ingroup identity as a mediator for the positive effects of intergroup contact.

Long Term Outcome

ObjectiveAlthough prescription rates of antidepressants for children and adolescents have increased, concerns have been raised regarding effects on neurodevelopment and long-term outcome. Using a genetic animal model of depression, this study investigated the long-term effects of pre-pubertal administration of fluoxetine (FLX) on depressive-like behaviour in early adulthood, as well as on central monoaminergic response to an acute stressor. We postulated that pre-pubertal FLX will have lasting effects on animal behaviour and monoaminergic stress responses in early adulthood.MethodsFlinders sensitive line (FSL) rats received 10 mg/kg/day FLX subcutaneously from postnatal day 21 (PnD21) to PnD34 (pre-pubertal). Thereafter, following normal housing, rats were either subjected to locomotor testing and the forced swim test (FST) on PnD60 (early adulthood), or underwent surgery for microdialysis, followed on PnD60 by exposure to acute swim stress and measurement of stressor-induced changes in plasma corticosterone and pre-frontal cortical monoamine concentrations.ResultsPre-pubertal FLX did not induce a late emergent effect on immobility in FSL rats on PnD60, whereas locomotor activity was significantly decreased. Acute swim stress on PnD60 significantly increased plasma corticosterone levels, and increased pre-frontal cortical norepinephrine (NE) and 5-hydroxyindole-3-acetic acid (5-HIAA) concentrations. Pre-pubertal FLX significantly blunted the pre-frontal cortical NE and 5-HIAA response following swim stress on PnD60. Baseline dopamine levels were significantly enhanced by pre-pubertal FLX, but no further changes were induced by swim stress.ConclusionPre-pubertal FLX did not have lasting antidepressant-like behavioural effects in genetically susceptible, stress-sensitive FSL rats. However, such treatment reduced locomotor activity, abrogated noradrenergic and serotonergic stressor responses and elevated dopaminergic baseline levels in adulthood.

The Relationship

Adolescents face high rates of victimization, yet little is known regarding the criminal consequences of these experiences. Using data from the National Youth Survey, this investigation compared the relative and combined effects of adolescent violent victimization perpetrated by family and nonfamily members on self-reported criminal offending from adolescence to early adulthood. The results demonstrate that both types of violence have an immediate and sustained impact on criminal involvement, although the effect is somewhat stronger for nonfamily victimization, and for both types, the relationship tends to weaken over time. In addition, those experiencing both types of victimization report a higher frequency of offending compared to those experiencing only one type. The findings indicate the need for prevention programs aimed at decreasing the prevalence of adolescent victimization, as well as intervention efforts to help victims from becoming offenders.

Political Scene

How does political socialization in a highly fragmented political scene affect propensity to vote? This article focusses on the long-term relationship between the number of political parties and the propensity to turn out in 96 parliamentary elections between 1996 and 2016 of nearly 100,000 individuals in 31 countries. Although intuitively more options might be expected to translate into a greater likelihood of participating in elections, existing research claims that high levels of party fragmentation instead lead to ‘choice overload’ and alienate citizens from voting. Building on the theory of voting as a habit, I show that early adulthood political socialization in a highly fragmented context leaves a footprint of non-voting in subsequent elections. This finding is especially relevant given the recent significant rise in fragmentation of most party systems in Europe, which in light of this research could mean a further decline in turnout rates in many countries in the future.

Preterm neonates are born while nephrogenesis is ongoing and are commonly exposed to factors in the extrauterine environment that may impair renal development. Supplemental oxygen therapy exposes the preterm infant to a hyperoxic environment that may induce oxidative stress. Our aim was to determine the immediate and long-term effects of exposure to hyperoxia, during the period of postnatal nephrogenesis, on renal development. Newborn mice (C57BL/6J) were kept in a normoxic (room air, 21% oxygen) or a controlled hyperoxic (65% oxygen) environment from birth to postnatal day 7 ( P7d). From P7d, animals were maintained in room air until early adulthood at postnatal day 56 ( P56d) or middle age (10 mo; P10mo). Pups were assessed for glomerular maturity and renal corpuscle cross-sectional area at P7d (control n = 14; hyperoxic n = 14). Nephron number and renal corpuscle size were determined stereologically at P56d (control n = 14; hyperoxic n = 14) and P10mo (control n = 10; hyperoxic n = 10). At P7d, there was no effect of hyperoxia on glomerular size or maturity. In early adulthood ( P56d), body weights, relative kidney weights and volumes, and nephron number were not different between groups, but the renal corpuscles were significantly enlarged. This was no longer evident at P10mo, with relative kidney weights and volumes, nephron number, and renal corpuscle size not different between groups. Furthermore, hyperoxia exposure did not significantly accelerate glomerulosclerosis in middle age. Hence, our findings show no overt long-term deleterious effects of early life hyperoxia on glomerular structure.
