Helping or Hovering? The Effects of Helicopter Parenting on College Students’ Well-Being

Parental involvement is related to many positive child outcomes, but if not developmentally appropriate, it can be associated with higher levels of child anxiety and depression. Few studies have examined the effects of over-controlling parenting, or “helicopter parenting,” in college students. Some studies have found that college students of over-controlling parents report feeling less satisfied with family life and have lower levels of psychological well-being. This study examined self-determination theory as the potential underlying mechanism explaining this relationship. College students (N = 297) completed measures of helicopter parenting, autonomy supportive parenting, depression, anxiety, satisfaction with life, and basic psychological needs satisfaction. Students who reported having over-controlling parents reported significantly higher levels of depression and less satisfaction with life. Furthermore, the negative effects of helicopter parenting on college students’ well-being were largely explained by the perceived violation of students’ basic psychological needs for autonomy and competence.     

Does a simultaneous memory load affect older and younger adults’ implicit associative learning?

This study investigated the effects of a simultaneous memory load on implicit associative sequence learning using the Triplets Learning Task (TLT). Participants in the Simultaneous condition held a secondary task memory load during the TLT, while those in the Sequential condition also performed both tasks, but successively, rather than simultaneously. Thus, the Simultaneous condition had a memory load during the TLT, while the Sequential condition did not. Probe blocks without the secondary task allowed separation of effects on learning from effects on its expression. Results revealed that the simultaneous memory load affected older, but not younger adults, by suppressing the expression of learning, not learning itself. Thus, older and younger adults can learn probabilistic associations while holding a simultaneous memory load, but the load can limit the extent to which older adults adapt their performance to environmental structure. Results are consistent with theories which propose that implicit associative learning does not call on limited capacity resources, and highlight the importance of distinguishing effects of dual tasks on the expression of learning from those on learning itself.     

A group-specific arbitrary tradition in chimpanzees (Pan troglodytes)

Social learning in chimpanzees has been studied extensively and it is now widely accepted that chimpanzees have the capacity to learn from conspecifics through a multitude of mechanisms. Very few studies, however, have documented the existence of spontaneously emerged traditions in chimpanzee communities. While the rigour of experimental studies is helpful to investigate social learning mechanisms, documentation of naturally occurring traditions is necessary to understand the relevance of social learning in the real lives of animals. In this study, we report on chimpanzees spontaneously copying a seemingly non-adaptive behaviour (“grass-in-ear behaviour”). The behaviour entailed chimpanzees selecting a stiff, straw-like blade of grass, inserting the grass into one of their own ears, adjusting the position, and then leaving it in their ear during subsequent activities. Using a daily focal follow procedure, over the course of 1 year, we observed 8 (out of 12) group members engaging in this peculiar behaviour. Importantly, in the three neighbouring groups of chimpanzees (n = 82), this behaviour was only observed once, indicating that ecological factors were not determiners of the prevalence of this behaviour. These observations show that chimpanzees have a tendency to copy each other’s behaviour, even when the adaptive value of the behaviour is presumably absent.     

That's More Like It: Multiple Exemplars Facilitate Word Learning

Previous research indicates learning words facilitates categorisation. The current study explores how categorisation affects word learning. In the current study, we investigated whether learning about a category facilitates retention of newly learned words by presenting 2‐year‐old children with multiple referent selection trials to the same object category. In Experiment 1, children either encountered the same exemplar repeatedly or encountered multiple exemplars across trials. All children did very well on the initial task; however, only children who encountered multiple exemplars retained these mappings after a short delay. Experiment 2 replicated and extended this finding by exploring the effect of within‐category variability on children's word retention. Children encountered either narrow or broad exemplars across trials. Again, all children did very well on the initial task; however, only children who encountered narrow exemplars retained mappings after a short delay. Overall, these data offer strong evidence that providing children with the opportunity to compare across exemplars during fast mapping facilitates retention.

How Preschoolers' Social–Emotional Learning Predicts Their Early School Success: Developing Theory‐Promoting,Competency‐Based Assessments

Starting on positive trajectories at school entry is important for children's later academic success. Using partial least squares, we sought to specify interrelations among all theory‐based components of social–emotional learning (SEL), and their ability to predict later classroom adjustment and academic readiness in a modelling context. Consequently, self‐regulation, emotion knowledge, social problem solving, and social–emotional behaviour were assessed via direct assessment and observation for 101 preschoolers; teachers provided information on classroom adjustment through kindergarten and academic readiness in kindergarten. Our final outer (measurement) model showed robust latent variables for SEL components. Regarding the inner (structural) model, latent variables showed expected predictive relations among SEL components, and with later classroom adjustment and academic readiness: preschoolers' executive control predicted aspects of their social cognition (i.e., emotion knowledge and social problem solving) and emotionally negative/aggressive behaviour, and emotion knowledge predicted their emotionally regulated/prosocial behaviour. Further, most SEL components directly and/or indirectly predicted teachers' evaluations of later classroom adjustment and kindergarten academic readiness. Our findings extend our understanding of SEL during preschool, suggesting that early assessment and monitoring is possible using these instruments, and potentially aiding the development of programmes to maximize children's SEL in the service of early school success.

Healthcare Serial Killers as Confidence Men

Although there is adequate coverage of serial murder in the extant homicide literature, there is a lack of systematic examination of healthcare professionals who serially murder their patients. Using a sample of 58 healthcare serial killers located within North America, South America, and Europe between the years of 1970 and 2010, this study examines notable pre‐offense and post‐offense behaviours of healthcare serial killers. Patterns related to offender aetiology, victim cultivation, crime scene behaviour, and techniques of evasion were explored. The findings from this study suggest that the pre‐offense and post‐offense behaviours of healthcare serial killers can be conceptualised from the theoretical framework of confidence men or ‘con men’. The findings from this study also suggest that healthcare serial killings and offenders who perpetrate them continue to be elusive and warrant additional scholarly attention to reduce their likelihood of engaging in homicide undetected for extended time. Policy implications are also discussed. Copyright © 2013 John Wiley & Sons, Ltd.
