Investigating cognitive transfer within the framework of music practice: genetic pleiotropy rather than causality

The idea of far transfer effects in the cognitive sciences has received much attention in recent years. One domain where far transfer effects have frequently been reported is music education, with the prevailing idea that music practice entails an increase in cognitive ability (IQ). While cross‐sectional studies consistently find significant associations between music practice and IQ, randomized controlled trials, however, report mixed results. An alternative to the hypothesis of cognitive transfer effects is that some underlying factors, such as shared genes, influence practice behaviour and IQ causing associations on the phenotypic level. Here we explored the hypothesis of far transfer within the framework of music practice. A co‐twin control design combined with classical twin‐modelling based on a sample of more than 10,500 twins was used to explore causal associations between music practice and IQ as well as underlying genetic and environmental influences. As expected, phenotypic associations were moderate (r = 0.11 and r = 0.10 for males and females, respectively). However, the relationship disappeared when controlling for genetic and shared environmental influences using the co‐twin control method, indicating that a highly practiced twin did not have higher IQ than the untrained co‐twin. In line with that finding, the relationship between practice and IQ was mostly due to shared genetic influences. Findings strongly suggest that associations between music practice and IQ in the general population are non‐causal in nature. The implications of the present findings for research on plasticity, modularity, and transfer are discussed.     

A Dilemma for Calibrationism

The aim of this paper is to describe a problem for calibrationism: a view about higher order evidence according to which one's credences should be calibrated to one's expected degree of reliability. Calibrationism is attractive, in part, because it explains our intuitive judgments, and provides a strong motivation for certain theories about higher order evidence and peer disagreement. However, I will argue that calibrationism faces a dilemma: There are two versions of the view one might adopt. The first version, I argue, has the implausible consequence that, in a wide range of cases, calibrationism is the only constraint on rational belief. The second version, in addition to having some puzzling consequences, is unmotivated. At the end of the paper I sketch a possible solution.     

The Relationship Between Automatic Thoughts and Irrational Beliefs Predicting Anxiety and Depression

Cognitive behavioral approaches differ in their views on core cognitions and their hypothesized role in the etiology of depression and anxiety. The present study provides empirical evidence regarding the relationship between irrational beliefs and components of automatic thoughts and their role in the etiology of depression and anxiety. The present study utilized newer and improved questionnaires to assess components of irrational belief. Based on prior research by Safren et al. (Cogn Ther Res 24(3):327–344, 2000), a three-factor structure of the combined automatic thought questionnaires were utilized to measure components of automatic thoughts as they relate to depression and anxiety. Factor analytical methods were utilized to confirm the factor structure of the irrational beliefs and automatic thoughts components. Advanced path modeling was utilized to model the relationship between irrational beliefs and automatic thoughts in predicting anxiety and depression. The study used a sample of N = 542 undergraduate psychology students during stressful exam times. Results indicated that the irrational belief Demandingness represents a primary factor, followed by the secondary irrational beliefs as proposed by Rational Emotive Behavioral Theory. Selfdowning beliefs were fully mediated by depressive automatic thoughts in the case of depressive affect. Low frustration tolerance contributed unique variance to anxious and depressive affect that was not fully mediated by automatic thoughts. Results from the present study add empirical evidence that irrational beliefs indeed represent core and intermediary beliefs that lead to specific automatic thoughts, which is congruent with cognitive behavioral theory as proposed by Rational Emotive Behavioral Therapy.     

Paradoxes of “creativity”: Examining the creative process through an antenarrative lens

Accounts of the creative process tend to be retrospective and implicitly ground the creative act within the person, the mind, the moment, the idea; in doing so, they often miss the larger sociomaterial qualities that can provide us with important insights about the social relationality and playfulness of the creative process. In this article, we examine the creative process through an antenarrative lens that we consider very useful for theorizing the creative process from a cultural and sociomaterial perspective. More specifically, we argue that ‘having an idea’ is a contextualized and embodied process that can be regarded as an antenarrative of the overall creative process. We also discuss how the paradoxical relation between the formative and sudden manifestations of the creative act can be understood through the notion of play.     

Using Multiple Contexts and Retrieval Cues in Exposure-Based Therapy to Prevent Relapse in Anxiety Disorders

The benefits of exposure-based interventions for anxiety disorders are substantial but not stable for everyone, given that these interventions are often followed by relapse of symptoms. A body of research provides a background on how to add certain strategies in exposure-based therapy to prevent relapse in anxiety disorders. This review summarizes some of these strategies and provides clear-cut clinical implications. Studies that provide support for two types of strategies to prevent relapse have been reviewed—the use of multiple contexts and the use of retrieval cues. The use of multiple contexts reduces context and stimulus specificity of extinction learning during exposure, while the use of retrieval cues enhances memory (re)consolidation and retrieval after exposure. The described strategies to enhance the accessibility and therefore the retrievability of exposure-based learning to prevent relapse in anxiety disorders can be summarized as advice to conduct exposure under variable conditions. This way, the generalizability of what is learned during exposure to the patients’ daily life after treatment improves. Therefore, adding these strategies in the course of exposure-based treatment of anxiety disorders seems beneficial. However, future replications and translational studies are needed to verify ecological validity.     

Gesture as representational action: A paper about function

A great deal of attention has recently been paid to gesture and its effects on thinking and learning. It is well established that the hand movements that accompany speech are an integral part of communication, ubiquitous across cultures, and a unique feature of human behavior. In an attempt to understand this intriguing phenomenon, researchers have focused on pinpointing the mechanisms that underlie gesture production. One proposal––that gesture arises from simulated action (Hostetter & Alibali Psychonomic Bulletin & Review, 15, 495–514, 2008)––has opened up discussions about action, gesture, and the relation between the two. However, there is another side to understanding a phenomenon and that is to understand its function. A phenomenon’s function is its purpose rather than its precipitating cause––the why rather than the how. This paper sets forth a theoretical framework for exploring why gesture serves the functions that it does, and reviews where the current literature fits, and fails to fit, this proposal. Our framework proposes that whether or not gesture is simulated action in terms of its mechanism––it is clearly not reducible to action in terms of its function. Most notably, because gestures are abstracted representations and are not actions tied to particular events and objects, they can play a powerful role in thinking and learning beyond the particular, specifically, in supporting generalization and transfer of knowledge.     

Analogous selection processes in declarative and procedural working memory: N-2 list-repetition and task-repetition costs

Working memory (WM) holds and manipulates representations for ongoing cognition. Oberauer (Psychology of Learning and Motivation, 51, 45–100, 2009) distinguishes between two analogous WM sub-systems: a declarative WM which handles the objects of thought, and a procedural WM which handles the representations of (cognitive) actions. Here, we assessed whether analogous effects are observed when participants switch between memory sets (declarative representations) and when they switch between task sets (procedural representations). One mechanism assumed to facilitate switching in procedural WM is the inhibition of previously used, but currently irrelevant task sets, as indexed by n-2 task-repetition costs (Mayr & Keele, Journal of Experimental Psychology: General, 129(1), 4–26, 2000). In this study we tested for an analogous effect in declarative WM. We assessed the evidence for n-2 list-repetition costs across eight experiments in which participants switched between memory lists to perform speeded classifications, mental arithmetic, or a local recognition test. N-2 list-repetition costs were obtained consistently in conditions assumed to increase interference between memory lists, and when lists formed chunks in long-term memory. Further analyses across experiments revealed a substantial contribution of episodic memory to n-2 list-repetition costs, thereby questioning the interpretation of n-2 repetition costs as reflecting inhibition. We reanalyzed the data of eight task-switching experiments, and observed that episodic memory also contributes to n-2 task-repetition costs. Taken together, these results show analogous processing principles in declarative and procedural WM, and question the relevance of inhibitory processes for efficient switching between mental sets.     

Investigating the effectiveness of brief cognitive reappraisal training to reduce fear in adolescents

As adolescent anxiety is common and costly, identifying effective strategies to reduce symptoms is a priority. This study tested whether adolescents could learn to use cognitive reappraisal strategies to attenuate fear during extinction learning. Fifty-seven participants (12–15 years) viewed images of two neutral faces, one which was paired with a fearful expression and shrieking scream (conditioned threat stimulus) and the other that was never paired with the aversive outcome (conditioned safety stimulus) during fear acquisition. Before extinction, participants either received cognitive appraisal training, which explored alternative, benign meanings associated with the scream or a control activity. Self-reported fear ratings in the cognitive reappraisal group were significantly lower to both the conditioned threat and safety stimuli after extinction than the control group. These findings did not characterise fear-potentiated startle data. Potential reasons for the lack of consistency between measures are considered.     

The Dark Side of Heterosexual Romance: Endorsement of Romantic Beliefs Relates to Intimate Partner Violence

Romance and control are often conflated by the media, and individuals may believe that certain controlling or jealous behaviors by men toward women are romantic and can be a sign of love and commitment in heterosexual relationships. The current study explored three types of romantic beliefs among women: endorsement of the ideology of romanticism, highly valuing romantic relationships, and the belief that jealousy is good. The goal was to determine whether these beliefs would be related to finding controlling behaviors romantic as well as to reported experiences of both physical and psychological intimate partner violence (IPV). We surveyed 275 heterosexual-identified women, aged 18 to 50, and measured their endorsement of romantic beliefs, the extent to which they romanticized controlling behavior, and experiences of physical and psychological abuse within their current or most recent romantic relationship. Romantic beliefs were related to romanticizing controlling behaviors, which, in turn, was related to experiences of IPV. There was also a significant indirect relationship between romantic beliefs and experiences of IPV. The data indicate that seemingly positive romantic ideologies can have insidious negative effects. Findings may be useful for clinicians and those who advocate for prevention of IPV as they illustrate a need to refocus traditional ideas of healthy relationships at the societal level.
