Experiences of activity and causality in schizophrenia: When predictive deficits lead to a retrospective over-binding

In this paper I discuss an intriguing and relatively little studied symptomatic expression of schizophrenia known as experiences of activity in which patients form the delusion that they can control some external events by the sole means of their mind. I argue that experiences of activity result from patients being prone to aberrantly infer causal relations between unrelated events in a retrospective way owing to widespread predictive deficits. Moreover, I suggest that such deficits may, in addition, lead to an aberrant intentional binding effect i.e., the subjective compression of the temporal interval between an intentional action and its external effects (Haggard et al., 2002a, Haggard et al., 2002b). In particular, it might be that patient’s thoughts are bound to the external events they aimed to control producing, arguably, a temporal contiguity between these two components. Such temporal contiguity would reinforce or sustain the (causal) feeling that the patient mind is directly causally efficient.     

Discourse on medicine: meditative and calculative approaches to ethics from an international perspective

Heidegger’s two modes of thinking, calculative and meditative, were used as the thematic basis for this qualitative study of physicians from seven countries (Canada, China, India, Ireland, Japan, Korea, & Thailand). Focus groups were conducted in each country with 69 physicians who cared for the elderly. Results suggest that physicians perceived ethical issues primarily through the lens of calculative thinking (76%) with emphasis on economic concerns. Meditative responses represented 24% of the statements and were mostly generated by Canadian physicians whose patients typically were not faced with economic barriers to treatment due to Canada’s universal health care system.     

Exploring the Hierarchical Structure of the MMPI–2–RF Personality Psychopathology Five in Psychiatric Patient and University Student Samples

In this study our goal was to examine the hierarchical structure of personality pathology as conceptualized by Harkness and McNulty's (1994) Personality Psychopathology Five (PSY–5) model, as recently operationalized by the MMPI–2–RF (Ben-Porath & Tellegen, 2011) PSY–5r scales. We used Goldberg's (2006) “bass-ackwards” method to obtain factor structure using PSY–5r item data, successively extracting from 1 to 5 factors in a sample of psychiatric patients (n = 1,000) and a sample of university undergraduate students (n = 1,331). Participants from these samples had completed either the MMPI–2 or the MMPI–2–RF. The results were mostly consistent across the 2 samples, with some differences at the 3-factor level. In the patient sample a factor structure representing 3 broad psychopathology domains (internalizing, externalizing, and psychoticism) emerged; in the student sample the 3-factor level represented what is more commonly observed in “normal-range” personality models (negative emotionality, introversion, and disconstraint). At the 5-factor level the basic structure was similar across the 2 samples and represented well the PSY–5r domains.     

Self-control in rhesus macaques (Macaca mulatta): controlling for differential stimulus exposure

Previous research on self-control using macaques (Macaca fascicularis) showed these animals have a strong bias for a delayed, larger reinforcer (Self-control) over an immediate, smaller reinforcer (Impulsive). Typical studies of self-control have used a discrete trials methodology with a secondary discriminative stimulus during the delay periods. This results in a greater exposure to the stimulus representing the self-controlled option and may account for some of the early exclusive preference for self-control observed. The present experiment examined self-control bias in three rhesus macaques (Macaca mulatta) while controlling for differential durations of stimulus exposure. Subjects were presented stimuli via a computer monitor and made choices by touching the stimulus at which point both stimuli were removed for the delay periods. All three subjects displayed a nearly exclusive bias for the delayed, larger reinforcer self-control). These results are consistent with previous studies, despite the variations in methodology and species.     

Confirming Gender Stereotypes: A Social Role Perspective

In this research we examined whether emotional vulnerability leads women and men to confirm gender stereotypes. Emotional vulnerability is a state where one is open to having one's feelings hurt or to experiencing rejection. Drawing on the tenets of social role theory and research related to normative expectations, we propose that emotional vulnerability leads to stereotype confirmation, as normative expectations are less risky and easier to enact than nonnormative behavior. Fifty-nine dating couples were randomly assigned to a high emotional vulnerability or low emotional vulnerability discussion with their partners. When the degree of emotional vulnerability was high men confirmed gender-stereotypes. Women's behavior, on the other hand, was not significantly affected by condition. We discuss these findings in terms of the domain in which gender-typed behaviors occur and the social pressures to act in accordance with gender norms.     

Emergent persons

Recent psychological theorizing about the emergence of persons makes a number of ontological claims that are not always explicit. A critical consideration of such claims reveals both considerable convergence and some points of disagreement across different psychological theories of emergent personhood. What is clear is that all such theories resist the reduction of persons to biophysical or sociocultural properties, conditions, and processes. In various ways, they each call for a nonreductionistic recognition of the sociocultural constitution of important aspects of personhood, without denying the necessity of biophysical requirements of personhood. Because standard emergentist positions in physical science and the philosophy of physical science mostly ignore the sociocultural level of reality, psychological theorizing about the emergence of persons requires an alternative ontological framework. It is proposed that an ontology of levels of reality that includes the physical, chemical, biological, sociocultural, and personal/psychological is appropriate for understanding how persons are both substantively and relationally emergent within the biophysical, sociocultural world. With such an ontological framework in place, it is possible to understand human activity in the world as the primary vehicle for both the phylogenetic evolution and ontogenetic development of persons.
