Interference due to shared features between action plans is influenced by working memory span

In this study, we examined the interactions between the action plans that we hold in memory and the actions that we carry out, asking whether the interference due to shared features between action plans is due to selection demands imposed on working memory. Individuals with low and high working memory spans learned arbitrary motor actions in response to two different visual events (A and B), presented in a serial order. They planned a response to the first event (A) and while maintaining this action plan in memory they then executed a speeded response to the second event (B). Afterward, they executed the action plan for the first event (A) maintained in memory. Speeded responses to the second event (B) were delayed when it shared an action feature (feature overlap) with the first event (A), relative to when it did not (no feature overlap). The size of the feature-overlap delay was greater for low-span than for high-span participants. This indicates that interference due to overlapping action plans is greater when fewer working memory resources are available, suggesting that this interference is due to selection demands imposed on working memory. Thus, working memory plays an important role in managing current and upcoming action plans, at least for newly learned tasks. Also, managing multiple action plans is compromised in individuals who have low versus high working memory spans.     

Evolution and the meaning of being: Heidegger,Jonas and Nihilism

Hans Jonas accuses Heidegger of “never bring[ing] his question about Being into correlation with the testimony of our physical and biological evolution.” Neither the early nor later Heidegger has a “philosophy of nature,” Jonas charges, because Naturphilosophie demands a new concept of matter, a monistic account of cosmogony and evolution, and the grounding of ethical responsibility for future generations in an ontological “first principle.” Jonas’s ontological rethinking of Darwinism allows him to overcome the nihilism that a mechanistic interpretation of evolution forces upon us: a nihilism allegedly shared by Heidegger. I imagine a Heideggerian response to Jonas, and ask whether the dream of recovering a synthesis between cosmogony and moral insight has been irrecoverably shattered by modern natural science.     

Art Making and Identity Formation in Children and Adolescents with Differing Social Behaviors

Not everyone develops social behaviors and interaction skills in an expected manner. This study explored the relationship between art making and identity formation in children and adolescents who were identified as having differing social behaviors. In three small group settings, 17 participants created abstract self-portraits from modeling compound and responded to questions about their self, self-concept, and self-esteem. From this, a model was created to describe identity formation as it relates to the relationships between social environment, desired occupations and activities, and creativity. Practice guidelines are proposed for those who provide children and adolescents with opportunities to make art as part of sessions aimed to promote the development of a healthy self-concept.     

Locus of Control and Academic Engagement: Mediating Role of Religious Commitment

Earlier studies have shown that locus of control is related to academic processes and outcomes. However, the nature of the relationship between locus of control, religious commitment, and academic engagement is unclear. This study examined the mediating role of religious commitment in linking locus of control with academic engagement, as well as the engagement dimensions - vigour, dedication, and absorption. Four hundred and eight university students completed the Locus of Control Behaviour Scale, Religious Commitment Inventory and Utrecht Work Engagement Scale – Student version. Locus of control was found to be positively related to the outcome variables. Intrapersonal religious commitment was positively related to the outcome variables. Interpersonal religious commitment did not have a significant relationship with vigour and absorption but it was significantly related to dedication and the total scores of academic engagement. Structural equation modelling analyses indicated significant paths from locus of control to academic engagement through both intrapersonal religious commitment and interpersonal religious commitment. Locus of control and religious commitment are suggested to be relevant in programmes and interventions to enhance academic engagement.     

Responses to critics

In response to points raised by our critics in this book symposium, we offer some clarifications about how to understand the role of science in assessing the multiple realization thesis. We also consider the connection between functionalism and multiple realization in the contexts of both psychological and biological sciences.     

Are Automatic Conceptual Cores the Gold Standard of Semantic Processing? The Context‐Dependence of Spatial Meaning in Grounded Congruency Effects

According to grounded cognition, words whose semantics contain sensory‐motor features activate sensory‐motor simulations, which, in turn, interact with spatial responses to produce grounded congruency effects (e.g., processing the spatial feature of up for sky should be faster for up vs. down responses). Growing evidence shows these congruency effects do not always occur, suggesting instead that the grounded features in a word's meaning do not become active automatically across contexts. Researchers sometimes use this as evidence that concepts are not grounded, further concluding that grounded information is peripheral to the amodal cores of concepts. We first review broad evidence that words do not have conceptual cores, and that even the most salient features in a word's meaning are not activated automatically. Then, in three experiments, we provide further evidence that grounded congruency effects rely dynamically on context, with the central grounded features in a concept becoming active only when the current context makes them salient. Even when grounded features are central to a word's meaning, their activation depends on task conditions.     

The “Good” Psychologist, “Good” Torture,and “Good” Reputation—Response to O’Donohue,Snipes, Dalto,Soto, Maragakis,and Im (2014) “The Ethics of Enhanced Interrogations and Torture”

O’Donohue et al. (2014) sought to derive, from classical ethical theories, the ethical obligation of psychologists to assist “enhanced interrogations and torture” (EIT) in national defense scenarios under strict EIT criteria. They asked the American Psychological Association to adopt an ethics code obligating psychologists to assist such EIT and to uphold the reputation of EIT psychologists. We contest the authors’ ethical analyses as supports for psychologists’ forays into torture interrogation when (if ever) the EIT criteria obtain. We also contend that the authors’ application of these ethical analyses violates the Geneva Conventions, contravenes military doctrine and operations, and undermines psychology as a profession. We conclude that “good” public reputation is not owed to, or expected by, “good” intelligence professionals, and collaborating operational psychologists must share their providence.
