On some recent moves in defence of doxastic compatibilism

According to the doxastic compatibilist, compatibilist criteria with respect to the freedom of action rule-in our having free beliefs. In Booth (Philosophical Papers 38:1–12, 2009), I challenged the doxastic compatibilist to either come up with an account of how doxastic attitudes can be intentional in the face of it very much seeming to many of us that they cannot. Or else, in rejecting that doxastic attitudes need to be voluntary in order to be free, to come up with a principled account of how her criteria of doxastic freedom are criteria of freedom. In two recent papers, Steup (Synthese 188:145–163, 2012; Dialectica 65(4):559–576, 2011) takes up the first disjunct of the challenge by proposing that even though beliefs cannot be practically intentional, they can be epistemically intentional. McHugh (McHugh forthcoming) instead takes up the second disjunct by proposing that the freedom of belief be modelled not on the freedom of action but on the freedom of intention. I argue that both Steup’s and McHugh’s strategies are problematic.     

Mechanisms of motivation–cognition interaction: challenges and opportunities

Recent years have seen a rejuvenation of interest in studies of motivation–cognition interactions arising from many different areas of psychology and neuroscience. The present issue of Cognitive, Affective, & Behavioral Neuroscience provides a sampling of some of the latest research from a number of these different areas. In this introductory article, we provide an overview of the current state of the field, in terms of key research developments and candidate neural mechanisms receiving focused investigation as potential sources of motivation–cognition interaction. However, our primary goal is conceptual: to highlight the distinct perspectives taken by different research areas, in terms of how motivation is defined, the relevant dimensions and dissociations that are emphasized, and the theoretical questions being targeted. Together, these distinctions present both challenges and opportunities for efforts aiming toward a more unified and cross-disciplinary approach. We identify a set of pressing research questions calling for this sort of cross-disciplinary approach, with the explicit goal of encouraging integrative and collaborative investigations directed toward them.     

Neuropsychological function and memory suppression in conversion disorder

Conversion disorder (CD) is a condition where neurological symptoms, such as weakness or sensory disturbance, are unexplained by neurological disease and are presumed to be of psychological origin. Contemporary theories of the disorder generally propose dysfunctional frontal control of the motor or sensory systems. Classical (Freudian) psychodynamic theory holds that the memory of stressful life events is repressed. Little is known about the frontal (executive) function of these patients, or indeed their general neuropsychological profile, and psychodynamic theories have been largely untested. This study aimed to investigate neuropsychological functioning in patients with CD, focusing on executive and memory function. A directed forgetting task (DFT) using words with variable emotional valence was also used to investigate memory suppression. 21 patients and 36 healthy controls completed a battery of neuropsychological tests and patients had deficits in executive function and auditory‐verbal (but not autobiographical) memory. The executive deficits were largely driven by differences in IQ, anxiety and mood between the groups. A subgroup of 11 patients and 28 controls completed the DFT and whilst patients recalled fewer words overall than controls, there were no significant effects of directed forgetting or valence. This study provides some limited support for deficits in executive, and to a lesser degree, memory function in patients with CD, but did not find evidence of altered memory suppression to support the psychodynamic theory of repression.     

Science and Political Imperatives: Orders of Precedence

An ideal view is sketched of the relationship between the facts established in science and the values of ethics and politics, and of the distinction between them. Some necessary qualifications are drawn, which do not essentially undermine the ideal. Then two cases of scientific work are considered in which considerations of value may in different ways be playing a more intimate role in the science than the ideal would suggest. These are Darwin’s theory of evolution and the current consensus on climate change. Are any general lessons to be drawn from these cases?     

Gifting Knowledge for Long Life

During nonemergency appointments at traditional sites of āyurvedic healthcare in Kerala, South India, classically trained Brāhma?a physicians and their patients seldom exchange anything of substance (whether medicinal or monetary). The physician-patient interface instead routinely involves an exchange of knowledge. Interactions between physicians and patients in these meetings evoke the highly theorized notion of the “Indian gift” and the question of prestation in South Indian societies. This article explores the nature of exchange in the supply and reception of healthcare among physicians and patients at traditional sites of āyurvedic treatment (that is, sites not affiliated with governmental or private hospitals or clinics) in contemporary Kerala. Drawing on classical treatises about the dharma of gifts (dānadharma) and the Sanskrit medical classics of āyurveda, it examines reciprocity, ideal preconditions of givers and receivers of gifts, and the possibility of a “pure gift” in the appraisal and production of wellbeing.     

The Development,Pilot, and Process Evaluation of a Parent Mental Health Literacy Intervention Through Community Sports Clubs

The mental health literacy of parents may be critical in facilitating positive child and adolescent mental health outcomes. The purpose of this study was to develop, pilot, and evaluate a targeted parent mental health literacy intervention through community sports clubs. Sixty six parents (M_age?=?44.86?±?5.2 years) participated in either a brief mental health literacy intervention workshop delivered through community sporting clubs (n?=?42) or a community-matched control group (n?=?24). Participants’ mental health literacy was assessed at baseline, post-intervention and at 1 month follow-up. A mixed methods process evaluation was conducted with intervention participants to determine the acceptability and feasibility of the intervention. Participants in the experimental group showed greater increases in depression literacy, anxiety literacy, knowledge of help seeking options and confidence to assist an adolescent experiencing a mental health disorder, compared to those in the control group. Post-intervention changes in the experimental group were maintained at 1 month follow-up. A mixed methods process evaluation revealed that parents found the intervention content engaging, relevant to their needs, and practically useful in terms of actively supporting adolescent mental health. Findings provide evidence that a brief, targeted intervention through community sports clubs might be a particularly useful method of improving parental mental health literacy and facilitating positive youth mental health outcomes.     

Testing complex animal cognition: Concept learning,proactive interference,and list memory

This article describes an approach for assessing and comparing complex cognition in rhesus monkeys and pigeons by training them in a sequence of synergistic tasks, each yielding a whole function for enhanced comparisons. These species were trained in similar same/different tasks with expanding training sets (8, 16, 32, 64, 128 … 1024 pictures) followed by novel‐stimulus transfer eventually resulting in full abstract‐concept learning. Concept‐learning functions revealed better rhesus transfer throughout and full concept learning at the 128 set, versus pigeons at the 256 set. They were then tested in delayed same/different tasks for proactive interference by inserting occasional tests within trial‐unique sessions where the test stimulus matched a previous sample stimulus (1, 2, 4, 8, 16 trials prior). Proactive‐interference functions revealed time‐based interference for pigeons (1, 10 s delays), but event‐based interference for rhesus (no effect of 1, 10, 20 s delays). They were then tested in list‐memory tasks by expanding the sample to four samples in trial‐unique sessions (minimizing proactive interference). The four‐item, list‐memory functions revealed strong recency memory at short delays, gradually changing to strong primacy memory at long delays over 30 s for rhesus, and 10 s for pigeons. Other species comparisons and future directions are discussed.
