Developmental trajectories of internalising behaviour in the prediction of adolescent depressive symptoms

Using a community‐based Australian birth cohort, groups with distinct longitudinal profiles (trajectories) of internalising behaviour from early childhood through mid‐adolescence were identified for boys and girls from parent ratings. Six internalising trajectories were identified for both genders, comprising stable, decreasing, and increasing pathways. Hierarchical regression models predicted the contribution of internalising trajectories to self‐reported age 17 depressive symptoms for males (n = 557) and females (n = 633), after controlling for the effects of a range of adolescent precursors. Internalising trajectories and adolescent psychosocial factors, each contributed to the prediction of subsequent depressive symptoms, with girls and boys on increasing internalising trajectories and boys on a fluctuating high trajectory particularly at risk. Results suggest that parent ratings can identify coherent internalising behaviour pathways that originate early in life and influence subsequent adjustment.     

Reasoning under Scarcity

Practical deliberation consists in thinking about what to do. Such deliberation is deemed rational when it conforms to certain normative requirements. What is often ignored is the role that an agent's context can play in so-called ‘failures’ of rationality. In this paper, I use recent cognitive science research investigating the effects of resource-scarcity on decision-making and cognitive function to argue that context plays an important role in determining which norms should structure an agent's deliberation. This evidence undermines the view that the norms of ‘ideal’ rationality are necessary and universal requirements on deliberation. They are a solution to the problems faced by cognitively limited agents in a context of moderate scarcity. In a context of severe scarcity, the problems faced by cognitively limited agents are different and require deliberation structured by different norms. Agents reason rationally when they use the norms best suited to their context and cognitive capacities.     

Measuring Probabilistic Reasoning: The Construction of a New Scale Applying Item Response Theory

Probabilistic reasoning skills are important in various contexts. The aim of the present study was to develop a new instrument (the Probabilistic Reasoning Scale – PRS) to accurately measure low levels of probabilistic reasoning ability in order to identify people with difficulties in this domain. Item response theory was applied to construct the scale, and to investigate differential item functioning (i.e., whether the items were invariant) across genders, educational levels, and languages. Additionally, we tested the validity of the scale by investigating the relationships between the PRS and several other measures. The results revealed that the items had a low level of difficulty. Nonetheless, the discriminative measures showed that the items can discriminate between individuals with different trait levels, and the test information function showed that the scale accurately assesses low levels of probabilistic reasoning ability. Additionally, through investigating differential item functioning, the measurement equivalence of the scale at the item level was confirmed for gender, educational status, and language (i.e., Italian and English). Concerning validity, the results showed the expected correlations with numerical skills, math‐related attitudes, statistics achievement, IQ, reasoning skills, and risky choices both in the Italian and British samples. In conclusion, the PRS is an ideal instrument for identifying individuals who struggle with basic probabilistic reasoning, and who could be targeted by specific interventions.

Inferential basing and mental models

In this paper, I flesh out an account of the inferential basing relation using a theory about how humans reason: the mental models theory. I critically assess some of the notions that are used by that theory to account for inferential phenomena. To the extent that the mental models theory is well confirmed, that account of basing would be motivated on empirical grounds. This work illustrates how epistemologists could offer explications of the basing relation which are more detailed and less empirically risky.     

Defeasibility and Inferential Particularism

In this paper I argue that defeasible (nonmonotonic) inferences are occasion-sensitive: the inferential connections of a given claim (plus collateral premises) depend on features of the circumstances surrounding the occasion of inference (including typical environmental conditions, and also pragmatic and contextual factors, such as the information available to agents and how high stakes are). More specifically, it is an occasion-sensitive matter which possible defeaters have to be considered explicitly by the premises of an inference and which possible defeaters may remain unconsidered, without making the inference enthymematic. As a result, a largely unexplored form of occasion-sensitivity arises in inferentialist theories of content that appeal to defeasible inferences.     

Associations Between Sport Participation,Goal and Sportspersonship Orientations,and Moral Reasoning

This study examined associations between level of sport participation, goal and sportspersonship orientations, and moral reasoning in sport and nonsport situations and orientation by sport participation interactions. Participants were individuals with elite (n = 176), high school (n = 183), and youth sport (n = 78) participation. When judging sport situations, individuals who participated in elite sports demonstrated poorer moral reasoning than those who participated in high school and youth sports. At low levels of sportspersonship, individuals who participated in youth sports demonstrated higher moral reasoning than those who participated in high school and elite sports. When judging nonsport situations, moral reasoning was positively related to positive sportspersonship and negatively related to ego orientation but did not differ by sport participation. Within sport, sport participation and goal and sportspersonship orientations play a critical role in moral reasoning. However, these orientations may be more important than sport participation in moral reasoning beyond the sport context.     

The effect of perspective-taking on reasoning about strong and weak belief-relevant arguments

This study investigated whether perspective-taking reduces belief bias independently of argument strength. Belief bias occurs when individuals evaluate belief-consistent arguments more favourably than belief-inconsistent arguments. Undergraduates (n = 93) read arguments that varied with respect to belief-consistency (i.e., belief-consistent or belief-inconsistent) and strength (i.e., strong or weak) about the topic of climate change. After participants read each argument, those in the perspective-taking condition rated the argument's strength from a perspective of a climate scientist and then from their own perspectives, whereas those in the no perspective-taking condition only rated the arguments from their own perspectives. Perspective-taking eliminated belief bias for weak arguments, but not for strong arguments. Theoretical and practical implications of the results are discussed, and directions for future research are provided.     

Perceived sources and levels of stress,general self-efficacy and coping strategies in clinical dental students

The aims of this study were to identify sources of stress among clinical students and to evaluate the students’ perceived levels of stress, general self-efficacy and effective coping strategies in a private dental school environment. The study group consisted of 130 undergraduate clinical dental students in a Turkish private dental school, during the academic year 2014–2015. The students were surveyed using modified version of the dental environment stress (DES) survey, the perceived stress scale, the general self-efficacy scale (G-SES) and the brief coping scale. Age, sex, year of study, history of psychiatric treatment and factors that affected the choice of dentistry were also recorded. Final year and female clinical dental students, who were found to be the most stressful students, had moderate to high perceived stress scores. Total and ‘Faculty and administration’ related DES scores increased with the year of study. Stressors related to ‘Workload’ and ‘Clinical training’ affected females more than males. G-SES scores were higher in male students and students, who had no history of psychiatric treatment. The most and the least common coping strategies were ‘Planning’ and ‘Substance abuse’, respectively. ‘Religion’ was found to be one of the main coping strategies. Stress factors affecting Turkish clinical dental students studying at private dental school differed from the previously reported stress factors affecting students studying at a governmental dental school. Advanced year and female students experienced more stress than the other students.
