Soap Opera Exposure and Enjoyment: A Longitudinal Test of Disposition Theory

Drama's appeal is driven in part by dispositions toward story characters and the deservingness of fortunes that befall them. This article reports the results of longitudinal research testing disposition theory's ability to predict viewer responses to daytime soap opera. A student sample completed a survey asking them to evaluate characters over 10 successive weeks. Measures of character morality and positive/negative outcomes for behaviors were used to predict the results of both viewer enjoyment and official Nielsen ratings in representative independent surveys covering the same 10 weeks. Consistent with disposition theory logic, an a priori specified interaction of character morality and behavioral outcome valence—the Disposition Vector Model—predicted higher Nielsen ratings and increased viewer enjoyment when benefaction/debasement befell characters morally deserving of these outcomes. Although well supported in short-term studies, to our knowledge this is the first study to support disposition theory over extended exposure to soap operas and predicting results in independent data sources.     

Visuo-Proprioceptive Matching Errors Are Consistent with Biases in Distance Judgments

People make systematic errors when matching the location of an unseen index finger with that of a visual target. These errors are consistent over time, but idiosyncratic and surprisingly task-specific. The errors that are made when moving the unseen index finger to a visual target are not consistent with the errors when moving a visual target to the unseen index finger. To test whether such inconsistencies arise because a large part of the matching errors originate during movement execution, we compared errors in moving the unseen finger to a target with biases in deciding which of two visual targets was closer to the index finger before the movement. We found that the judgment as to which is the closest target was consistent with the matching errors. This means that inconsistencies in visuo-proprioceptive matching errors are not caused by systematic errors in movement execution, but are likely to be related to biases in sensory transformations.     

Domain‐specific impulsivity in school‐age children

Impulsivity is a salient individual difference in children with well‐established predictive validity for life outcomes. The current investigation proposes that impulsive behaviors vary systematically by domain. In a series of studies with ethnically and socioeconomically diverse samples of middle school students, we find that schoolwork‐related and interpersonal‐related impulsivity, as observed by teachers, parents, and the students themselves, are distinct, moderately correlated behavioral tendencies. Each demonstrates differentiated relationships with dimensions of childhood temperament, Big Five personality factors, and outcomes, such as report card grades. Implications for theoretical conceptions of impulsivity as well as for practical applications (e.g. domain‐specific interventions) are discussed.     

Later life health optimism,pessimism and realism: Psychosocial contributors and health correlates

Prior research has established positive outcomes of health optimism (appraising one's health as good despite poor objective health (OH)) and negative outcomes of health pessimism (appraising health as poor despite good OH), yet little is known about their contributors. We examined the role of psychosocial factors (life event stress, depression, dispositional optimism, perceived social support) in health realism (appraising health in accordance with OH), optimism and pessimism among 489 older men and women. We then accounted for the psychosocial factors when examining multiple health correlates of health realism, optimism and pessimism. Controlling for age, gender and income, regression results indicate that depression and social support were associated with less health optimism, while dispositional optimism was associated with greater health optimism among those in poor OH. Dispositional optimism was associated with less health pessimism and life event stress was associated with greater pessimism among those in good OH. Beyond the effects of the psychosocial factors, structural equation model results indicate that health optimism was positively associated with healthy behaviours and perceived control over one's health; health pessimism was associated with poorer perceived health care management. Health optimism and pessimism have different psychosocial contributors and health correlates, validating the health congruence approach to later life well-being, health and survival.     

Recommendations for Increasing Replicability in Psychology

Replicability of findings is at the heart of any empirical science. The aim of this article is to move the current replicability debate in psychology towards concrete recommendations for improvement. We focus on research practices but also offer guidelines for reviewers, editors, journal management, teachers, granting institutions, and university promotion committees, highlighting some of the emerging and existing practical solutions that can facilitate implementation of these recommendations. The challenges for improving replicability in psychological science are systemic. Improvement can occur only if changes are made at many levels of practice, evaluation, and reward.

Rey AVLT: Developmental Norms for Children and the Sensitivity of Different Memory Measures to Age

Nine hundred and forty-three children (487 boys and 456 girls, age range 8 to 17 years, divided into 10 age cohorts) were administered the Hebrew version of the Rey AVLT. Separate norms for boys and girls in each age group are reported. Sensitivity to age for 14 memory measures extracted from the Rey AVLT was analyzed. One of the most consistent findings across the different scores is that memory changes in the 8- to 10- year-old age range are more dynamic than changes in the 11- to 17- year-old age range. The results also show a significant and consistent advantage for girls over boys on most of the verbal memory measures. Detailed analyses of sensitivity to age of the different measures extracted from the Rey AVLT provide very useful information for the diagnostician testing auditory-verbal memory in children.

Dopamin-Dysregulations-Syndrom bei Morbus Parkinson

Parkinson’s disease is a neurodegenerative disease with the cardinal symptoms bradykinesia, rigidity and tremor. In 1817, James Parkinson already described in his "Essay on the Shaking Palsy" in addition to the motor symptoms also autonomic, cognitive and behavioral disturbances (Parkinson, An essay on the shaking palsy. Sherwood, Nealy and Jones, London, 1817). Their impact on quality of life has been underestimated until more recent times. Dopamine dysregulation syndrome is an iatrogenic disturbance, characterized by an addictive pattern of dopamine replacement therapy use. Despite good control of motor symptoms, patients often increase doses of dopamine replacement therapy in excess of those normally required. Consequently these behavioral disorders may also result in social and professional problems.     

Antipsychotic dose modulates behavioral and neural responses to feedback during reinforcement learning in schizophrenia

Schizophrenia is characterized by an abnormal dopamine system, and dopamine blockade is the primary mechanism of antipsychotic treatment. Consistent with the known role of dopamine in reward processing, prior research has demonstrated that patients with schizophrenia exhibit impairments in reward-based learning. However, it remains unknown how treatment with antipsychotic medication impacts the behavioral and neural signatures of reinforcement learning in schizophrenia. The goal of this study was to examine whether antipsychotic medication modulates behavioral and neural responses to prediction error coding during reinforcement learning. Patients with schizophrenia completed a reinforcement learning task while undergoing functional magnetic resonance imaging. The task consisted of two separate conditions in which participants accumulated monetary gain or avoided monetary loss. Behavioral results indicated that antipsychotic medication dose was associated with altered behavioral approaches to learning, such that patients taking higher doses of medication showed increased sensitivity to negative reinforcement. Higher doses of antipsychotic medication were also associated with higher learning rates (LRs), suggesting that medication enhanced sensitivity to trial-by-trial feedback. Neuroimaging data demonstrated that antipsychotic dose was related to differences in neural signatures of feedback prediction error during the loss condition. Specifically, patients taking higher doses of medication showed attenuated prediction error responses in the striatum and the medial prefrontal cortex. These findings indicate that antipsychotic medication treatment may influence motivational processes in patients with schizophrenia.
