Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms

Smári, J., Rúrik Martinsson, D., & Einarsson, H. (2010). Rearing practices and impulsivity/hyperactivity symptoms in relation to inflated responsibility and obsessive‐compulsive symptoms. Scandinavian Journal of Psychology, 51, 392–397. The aim of the study was to investigate potential precursors of inflated responsibility (responsibility attitudes) and obsessive‐compulsive (OCD) symptoms. It was argued that both parental overprotection and impulsivity, separately and in interaction with each other, contribute to inflated responsibility and OCD symptoms. In a large sample of young adults (N = 570), self‐report measures of OCD symptoms (OCI‐R), responsibility attitudes (RAS), anxiety/depression (HADS), rearing practices (EMBU), present and past impulsivity/hyperactivity symptoms (IMP/HY) were administered. Overprotection as well as IMP/HY were found to predict OCD symptoms as well as inflated responsibility. Finally, a significant interaction was found between IMP/HY and overprotection with regard to both OCD symptoms and inflated responsibility. This effect reflected that IMP/HY was more strongly related to OCD symptoms and responsibility in people who had not been overprotected than in people who had been. Conversely overprotection was related to OCD symptoms and responsibility in people low but not in people high in IMP/HY. The results seem to indicate that the inadequacy between offer and need for parental control may play a role in the development of OCD symptoms.     

Monocular optical constraints on collision control

A simulated ball-hitting task was used to explore the optical basis for collision control. Ball speed and size were manipulated in Experiments 1 and 2. Results showed a tendency for participants to respond earlier to slower and larger balls. Early in practice, participants would consistently miss the slowest and largest balls. Experiments 3 and 4 examined performance as a function of the range of speeds. Performance for identical speeds differed depending on whether the speeds were fastest or slowest within a range. Asymmetric transfer between the 2 ranges of speeds showed that those trained with slow speeds were very successful when tested with a faster range of speeds. Those trained with fast speeds did not do as well when tested on slower speeds. The pattern of results across 4 experiments suggests that participants were using optical angle and expansion rate as separate degrees of freedom for solving the collision task.     

When a Non-resident Worker is a Non-resident Parent: Investigating the Family Impact of Fly-In,Fly-Out Work Practices in Australia

Non-resident work practices, which involve prolonged separations from family, long-distance commuting between home and remote work sites and long work hours across compressed rosters, are now commonplace in Australia. This study examined the impact of these work arrangements, often termed Fly-In/Fly-Out (FIFO), on children and families, and to identify family-related and employment-related factors that influence child and family outcomes. Anonymous online surveys containing measures of family and couple relationship quality, child behavioral and emotional adjustment, parenting and personal adjustment were completed by 232 partners of FIFO workers, 46 FIFO workers, and a comparison group of community parents (N = 294 mothers, N = 36 fathers). There were no differences between FIFO partners and community parents on family or couple relationship quality, parenting competence and child behavioral or emotional difficulties. FIFO partners reported higher levels of personal emotional problems and greater usage of harsh discipline practices than community mothers, while FIFO workers reported greater work to family conflict and alcohol use than community fathers. Regression analyses on the FIFO partners sample indicated that child and family functioning were best predicted by family factors, including harsh parenting and parental emotional adjustment. Implications of the findings for the design and provision of family-based support for FIFO families are discussed.
