A Population‐Based Comparison of Female and Male Same‐Sex Parent and Different‐Sex Parent Households

This investigation compared Dutch same‐sex parent and different‐sex parent households on children's psychological well‐being, parenting stress, and support in child rearing. It was also assessed whether associations among children's well‐being, parenting stress, and support in child rearing were different in the two household types. Data were based on a nationally representative survey (N = 25,250). Matching was used to enhance similarity in background characteristics between both types of families. Parental and child characteristics were matched for 43 female same‐sex parent, 52 male same‐sex parent, and 95 different‐sex parent households with offspring between 5 and 18 years old. No significant differences were found on children's well‐being, problems in the parent–child relationship, being worried about the child, or the use of formal and informal support between mothers in same‐sex and different‐sex parent households or for fathers in same‐sex and different‐sex parent households. Regarding perceived confidence in child rearing, fathers in same‐sex parent households and mothers in different‐sex parent households felt less competent than their counterparts. Neither the associations between children's well‐being and the predictors (parenting stress variables) nor those between support and the predictors (parenting stress and children's well‐being) differed along household type. In this population‐based study, the similarity in child outcomes regardless of household type confirms the results of prior investigations based on convenience samples. These findings are pertinent to family therapists, practitioners, court officials, and policymakers who seek information on parenting experiences and child outcomes in female and male same‐sex parent families.     

The presence of threat affects saccade trajectories

In everyday life, fast identification and processing of threat-related stimuli is of critical importance for survival. Previous studies suggested that spatial attention is automatically allocated to threatening stimuli, such as angry faces. However, in the previous studies the threatening stimuli were not completely irrelevant for the task. In the present study we used saccadic curvature to investigate whether attention is automatically allocated to threatening emotional information. Participants had to make an endogenous saccade up or down while an irrelevant face paired with an object was present in the periphery. The eyes curved away more from the angry faces than from either neutral or happy faces. This effect was not observed when the faces were inverted, excluding the possible role of low-level differences. Since the angry faces were completely irrelevant to the task, the results suggest that attention is automatically allocated to the threatening stimuli, which generates activity in the oculomotor system, and biases behaviour.     

Establishing preference for unreliable reinforcement in adults with dual diagnoses

We evaluated the choice responding of three adults dually diagnosed with developmental and psychiatric disabilities using concurrent schedules of reinforcement. Specifically, participants were given a choice between a response option resulting in reliable reinforcement and a response option resulting in unreliable reinforcement. Our primary purpose was to shift preference from reliable to unreliable reinforcement via the systematic presentation of stimuli during delay intervals. A second purpose was to evaluate the effectiveness of intervening stimuli in shifting preference at differing delay-to-reinforcement intervals. Preference for unreliable reinforcement was first examined in the absence of stimulus presentations during delays, at three different delay values. Next, we aimed to establish preference for unreliable reinforcement by presenting pictures of reinforcers during delays preceding unreliable reinforcement. Preference was again examined at three different delay values. In the absence of stimulus presentations during delays, participants were shown to prefer reliable reinforcement, particularly at the longer delay value. When stimuli were presented during the delays, two of the three participants preferred unreliable reinforcement, particularly the longer the delay value. These results suggest that the presentation of intervening stimuli during delays may help facilitate tolerance for unreliable reinforcement.
