Abstract

The aim of this paper is to identify what I take to be the main conceptual problem in Lewis’ semantics for counterfactuals when the Limit Assumption (LA) is not satisfied, what I call the Discrimination Problem (DP), and to present and discuss a modification of Lewis’ semantics that aims at solving DP. First, I outline Lewis’ semantics, highlighting the aspects that will be relevant for our discussion. Second, I present DP and discuss it with a heuristic example. Third, I present the new proposal and comment some formal consequences and the objections they give rise to. Fourth, I present an allegedly equivalent version of the proposal and discuss the difference between counterfactuals and strict conditionals. Finally, I defend that the two proposals are different and argue for the first one as the best way of capturing two intuitions that seem in conflict when the LA is not satisfied. I conclude with a dilemma: either the proposal here defended works or LA is inescapable. Thus, if the proposal doesn’t work, the paper must then be considered as an indirect defense of the Limit Assumption.     

Establishing a relational field that fosters learning processes: Some tentative propositions derived from trainee experiences

In this article, we look at the recent introduction of more relational-oriented learning principles and how they translate into practice by documenting the experiences of both trainees and instructors. It became clear that actors held different opinions and viewpoints on learning objectives and process ingredients for achieving these objectives. This divergence in opinions resulted in an “impoverished” learning trajectory. We suggest that remedying this situation implies introducing reflexivity regarding learning processes or, stated otherwise, addressing “meta-cognitions” that participants inevitably bring to the process as they affect the way in which people engage in the relational field that encompasses the learning trajectory. Despite some recent arguments in favour of a distinction between cognitive and meta-cognitive mediation, we argue for a similar approach with respect to both types of mediation. We end this article by suggesting that designing learning trajectories with this dual concern in mind might open the road to “learning to learn”.     

Emotions,narrative and change

There is a wide agreement that emotions are central to the evaluation and understanding of change processes in psychotherapy. Unfortunately, most of the debate on the role of emotions has been influenced by the reductionist view of ‘psychophysiological symbolism’ (Averill 1996). We defend the position that, in order to understand their role in psychotherapy fully, we need to move in the direction of a more complex view of emotions. This paper presents a view of emotionsas social constructed phenomena operating via language and narrative. We present research suggesting that these narratives may be an essential process for understanding psychological disorders, how these disorders are developed and, finally, how they can be changed.     

A Systematic Review of Propensity Score Methods in the Social Sciences

The use of propensity scores in psychological and educational research has been steadily increasing in the last 2 to 3 years. However, there are some common misconceptions about the use of different estimation techniques and conditioning choices in the context of propensity score analysis. In addition, reporting practices for propensity score analyses often lack important details that allow other researchers to confidently judge the appropriateness of reported analyses and potentially to replicate published findings. In this article we conduct a systematic literature review of a large number of published articles in major areas of social science that used propensity scores up until the fall of 2009. We identify common errors in estimation, conditioning, and reporting of propensity score analyses and suggest possible solutions.     

Mousetrap: An integrated,open-source mouse-tracking package

Mouse-tracking – the analysis of mouse movements in computerized experiments – is becoming increasingly popular in the cognitive sciences. Mouse movements are taken as an indicator of commitment to or conflict between choice options during the decision process. Using mouse-tracking, researchers have gained insight into the temporal development of cognitive processes across a growing number of psychological domains. In the current article, we present software that offers easy and convenient means of recording and analyzing mouse movements in computerized laboratory experiments. In particular, we introduce and demonstrate the mousetrap plugin that adds mouse-tracking to OpenSesame, a popular general-purpose graphical experiment builder. By integrating with this existing experimental software, mousetrap allows for the creation of mouse-tracking studies through a graphical interface, without requiring programming skills. Thus, researchers can benefit from the core features of a validated software package and the many extensions available for it (e.g., the integration with auxiliary hardware such as eye-tracking, or the support of interactive experiments). In addition, the recorded data can be imported directly into the statistical programming language R using the mousetrap package, which greatly facilitates analysis. Mousetrap is cross-platform, open-source and available free of charge from https://github.com/pascalkieslich/mousetrap-os.     

Observational Context of Mother-Child Interaction: Impact of a stress Context on Emotional Availability

Previous studies have found that a stressful observational context challenges the mother-child relationship, thus highlighting negative interactive behavior. However, the impact of observational context has only been investigated in infants and preschoolers without specifically using the Emotional Availability Scales. Nor have they explored whether the association of mother-child interaction with children’s emotional or behavioral problems depends on the observational context. We observed 140 mothers and their five to 12-year-old children in non-stressful free play and in a stressful task context. In general, dyads showed higher emotional availability in the task context compared to the free play. Specifically, mothers showed higher levels of Sensitivity, Structuring and Nonhostility, but lower levels of Nonintrusiveness during the task compared to the free play context; children showed higher levels of Responsiveness during the task than during free play. After controlling for dyadic stress, contextual effects decreased for all dimensions of emotional availability. The association of mother-child interaction with child problem behavior depended on the observational context. Specifically, we found maternal emotional availability during free play to be more strongly associated with child problem behavior than during the stressful task; however, emotional availability of the child was more strongly associated with problem behavior when obtained during the task. We conclude that context impacts on mother-child interactive behavior and also on the association of mother-child-interaction and child behavior. Stress is a relevant contextual factor influencing mother-child interactive behavior.     

Parents' education and children's achievement: The role of personality

The reasons for the positive association between families' background variables, such as parents' education, and children's academic achievement have not fully been clarified yet. The present study investigates children's intelligence and personality as potential mediators. A sample of 580 German high school students (mean age: M = 17.0; SD = 0.7) indicated the highest education of their parents and completed measures assessing their own personality and intelligence. Children's academic achievement was operationalized by grade point average. Children's intelligence, openness to experience and, marginally, conscientiousness partially mediated the association between parents' education and children's academic achievement. Even after controlling for children's intelligence, the mediating effects of those personality traits held. Results are discussed with regard to potential underlying processes.

The complexity of satisfiability for fragments of hybrid logic—Part I

The satisfiability problem of hybrid logics with the downarrow binder is known to be undecidable. This initiated a research program on decidable and tractable fragments.In this paper, we investigate the effect of restricting the propositional part of the language on decidability and on the complexity of the satisfiability problem over arbitrary, transitive, total frames, and frames based on equivalence relations. We also consider different sets of modal and hybrid operators. We trace the border of decidability and give the precise complexity of most fragments, in particular for all fragments including negation. For the monotone fragments, we are able to distinguish the easy from the hard cases, depending on the allowed set of operators.

Scoring Depression on a Common Metric: A Comparison of EAP Estimation,Plausible Value Imputation,and Full Bayesian IRT Modeling

There are a growing number of item response theory (IRT) studies that calibrate different patient-reported outcome (PRO) measures, such as anxiety, depression, physical function, and pain, on common, instrument-independent metrics. In the case of depression, it has been reported that there are considerable mean score differences when scoring on a common metric from different, previously linked instruments. Ideally, those estimates should be the same. We investigated to what extent those differences are influenced by different scoring methods that take into account several levels of uncertainty, such as measurement error (through plausible value imputation) and item parameter uncertainty (through full Bayesian IRT modeling). Depression estimates from different instruments were more similar, and their corresponding confidence/credible intervals were larger when plausible value imputation or Bayesian modeling was used, compared to the direct use of expected a posteriori (EAP) estimates. Furthermore, we explored the use of Bayesian IRT models to update item parameters based on newly collected data.
