Revisiting dispersion in count data item response theory models: The Conway–Maxwell–Poisson counts model

Count data naturally arise in several areas of cognitive ability testing, such as processing speed, memory, verbal fluency, and divergent thinking. Contemporary count data item response theory models, however, are not flexible enough, especially to account for over- and underdispersion at the same time. For example, the Rasch Poisson counts model (RPCM) assumes equidispersion (conditional mean and variance coincide) which is often violated in empirical data. This work introduces the Conway–Maxwell–Poisson counts model (CMPCM) that can handle underdispersion (variance lower than the mean), equidispersion, and overdispersion (variance larger than the mean) in general and specifically at the item level. A simulation study revealed satisfactory parameter recovery at moderate sample sizes and mostly unbiased standard errors for the proposed estimation approach. In addition, plausible empirical reliability estimates resulted, while those based on the RPCM were biased downwards (underdispersion) and biased upwards (overdispersion) when the simulation model deviated from equidispersion. Finally, verbal fluency data were analysed and the CMPCM with item-specific dispersion parameters fitted the data best. Dispersion parameter estimates indicated underdispersion for three out of four items. Overall, these findings indicate the feasibility and importance of the suggested flexible count data modelling approach.     

The Ethical Orientation of Russian Entrepreneurs

Ethics has been a significant concern in the management literature and recent efforts have investigated ethical orientations across culture. However, little, if any, work has looked at ethical orientations among entrepreneurs and managers in the transforming Russian economy. This study surveyed the ethical orientations of Russian owner-managers ( n =194) involved in entrepreneurial and privatisation activities. A cross-cultural comparison to US normative responses found no difference in Machiavellian orientation in general, though female Russian entrepreneurs perceived themselves as more likely to engage in opportunistic behaviour. Additionally, Russian entrepreneurs in general perceived themselves as more ethically rigid. These respondents also felt Russian organisations fostered more interpersonally collective but structurally opportunistic organisational climates.     

Understanding and Removing the Effects of Performance Cues on Behavioral Ratings

Previous research has demonstrated that performance information (e.g., prior supervisor ratings) can bias behavioral ratings. However, research has not fully explored the effects of performance cues on raters' memory. In addition, no studies have attempted to eliminate this performance cue effect. This study addressed these deficiencies by collecting both free recall and recognition memory measures while testing an unstructured free recall intervention. Results indicate that performance cues do affect the recall of performance relevant behaviors from memory. Contrary to expectations, free recall did not prove to be an effective intervention. Implications of these findings for future attempts to remove the performance cue effect are discussed.     

Why should we try to think like scientists? Scientific reasoning and susceptibility to epistemically suspect beliefs and cognitive biases

This paper examines whether scientific reasoning skills predict people's susceptibility to epistemically suspect beliefs and cognitive biases. We used the recently developed Scientific Reasoning Scale (SRS) because it measures the ability to read and evaluate scientific evidence. Alongside the SRS, 317 participants aged 18–30 years completed measures of thinking dispositions and cognitive ability to ascertain whether the SRS contributes specifically to susceptibility to epistemically suspect beliefs and cognitive biases. Scientific reasoning correlated positively with dispositions towards analytic thinking and cognitive ability and negatively with dogmatism, epistemically suspect beliefs, and susceptibility to cognitive biases. Most importantly, it emerged as a significant predictor, contributing to susceptibility to both cognitive biases and epistemically suspect beliefs over and above the other cognitive predictors. These results provide the first empirical evidence that scientific reasoning ability is an important factor in protecting against epistemically suspect beliefs and in aiding better decision making among the non-scientific population.

A Tripartite Approach to Right‐Wing Authoritarianism: The Authoritarianism‐Conservatism‐Traditionalism Model

Right‐Wing Authoritarianism (RWA) has been conceptualized and measured as a unidimensional personality construct comprising the covariation of the three traits of authoritarian submission, authoritarian aggression, and conventionalism. However, new approaches have criticized this conceptualization and instead viewed these three “traits” as three distinct, though related, social attitude dimensions. Here we extend this approach providing clear definitions of these three dimensions as ideological attitude constructs of Authoritarianism, Conservatism, and Traditionalism. These dimensions are seen as attitudinal expressions of basic social values or motivational goals that represent different, though related, strategies for attaining collective security at the expense of individual autonomy. We report data from five samples and three different countries showing that these three dimensions could be reliably measured and were factorially distinct. The three dimensions also differentially predicted interpersonal behaviour, social policy support, and political party support. It is argued that conceptualizing and measuring RWA as a set of three related ideological attitude dimensions may better explain complex sociopolitical phenomena than the currently dominant unidimensional personality based model.     

Reward-related brain function as a predictor of treatment response in adolescents with major depressive disorder

The present study provides preliminary evidence that pretreatment reward-related brain function in the striatum and medial prefrontal cortex (PFC) could have relevance for predicting both final level and rate of change of clinical characteristics in adolescents with major depressive disorder. Adolescents with depression underwent a functional MRI scan during a monetary reward task, participated in an 8-week open trial of cognitive behavioral therapy (CBT) or CBT plus selective serotonin reuptake inhibitor, and completed reports of anxiety and depressive symptoms before, during, and after treatment. Clinicians rated adolescents’ improvement and severity at the same time points. Growth models were used to examine change in clinical characteristics and its association with brain function. Severity, anxiety symptoms, and depressive symptoms decreased over treatment. Final levels of severity and anxiety symptoms were associated with pretreatment striatal reactivity, and rate of anxiety symptom reduction was associated with greater striatal reactivity and lower medial PFC reactivity.     

Callous-unemotional features, behavioral inhibition, and parenting: independent predictors of aggression in a high-risk preschool sample

A behaviorally-uninhibited temperament, callous-unemotional (CU) features, and harsh parenting have been associated with specific patterns of aggressive behavior in older children and adolescents. We tested the additive and interactive effects of these factors in predicting different types of aggressive behavior in a high-risk preschool sample. Forty-nine preschoolers and their parents registering for Head Start programs were recruited for participation. Behavioral inhibition, CU features, and attitudes toward various types of parenting were assessed through parent rating scales completed at the time of registration. Behavioral inhibition, CU features, and aggression were assessed by teacher ratings approximately six months later. Analyses revealed that behavioral inhibition, CU features, and harsh parental attitudes all contributed independently to the prediction of aggressive behavior. These associations were strongest for proactive types of aggression. Our results suggest that a behaviorally uninhibited temperament, CU features, and attitudes favoring harsh parenting are all important for understanding the development of aggression in preschool children.
