Matters temporal

Current evidence suggests that neural Hebbian learning in cortical and hippocampal synapses is fundamentally predictive rather than conventionally correlational. Much attention is focussing on what sort of predictions are acquired, and in what neural architectures. A recent paper by Rao and Sejnowski has suggested an interesting interpretation in terms of a popular predictive algorithm that has roots in psychology, computer science and engineering.     

“Not in My Back Yard”: The Situational and Personality Determinants of Oppositional Behavior1

The present study considered situational and dispositional factors underlying behavioral opposition characteristic of a “not‐in‐my‐back‐yard” (NIMBY) response to a change having adverse personal consequences. Students considered the proposition of comprehensive exams required for graduation taking effect in the near or distant future (high and low vested interest, respectively). Although both groups had similarly negative attitudes toward the idea, the high vested interest group perceived greater personal consequence and expressed greater intention to oppose the plan. From a situational‐dispositional interactionist perspective, it was the impact of the situation (perceived stake), rather than personality traits presumed to underlie a NIMBY response, that proved to be the primary determinant of oppositional behavior.

Positive and problematic dissertation experiences: The faculty perspective

We interviewed 14 clinical and counseling psychology faculty regarding their experiences chairing positive and problematic dissertations. Data were analyzed using consensual qualitative research (CQR). Participants reported that advisors’ roles involved guiding/facilitating dissertations and helping students shape research ideas; students’ roles included taking responsibility, working independently, and maintaining good relationships with the chair/committee. With positive dissertation experiences, chairs and students collaborated before the dissertation, worked together well during the dissertation, and students began the dissertation feeling competent and motivated; such dissertations positively affected participants. Problematic dissertation experiences evinced difficult relationships between chair and student, and students’ low research capability; such dissertations negatively affected participants.     

Decision theory,reinforcement learning,and the brain

Decision making is a core competence for animals and humans acting and surviving in environments they only partially comprehend, gaining rewards and punishments for their troubles. Decision-theoretic concepts permeate experiments and computational models in ethology, psychology, and neuroscience. Here, we review a well-known, coherent Bayesian approach to decision making, showing how it unifies issues in Markovian decision problems, signal detection psychophysics, sequential sampling, and optimal exploration and discuss paradigmatic psychological and neural examples of each problem. We discuss computational issues concerning what subjects know about their task and how ambitious they are in seeking optimal solutions; we address algorithmic topics concerning model-based and model-free methods for making choices; and we highlight key aspects of the neural implementation of decision making.     

Experiencing risk in person-centred counselling: a qualitative exploration of therapist risk-taking

With increasing emphasis being given to the importance of the relationship in counselling, this paper is based on an initial exploration of counsellors' experiences of risk when bringing their own person into play, and the way in which these experiences relate to the quality of psychological contact. Qualitative interviews with eight practising counsellors were conducted using a person-centred approach. Themes emerging included the process of risk-taking for counsellors, the process of reaction and response for clients and the effects on the relationship both in the immediate session and in the long term. Most participants expressed the view that the greatest impact of a critical moment of risk-taking was to facilitate deeper levels of contact, usually described in terms of being more 'authentic', ' real' and 'loving'. In a few cases the risk-taking intervention led to a rupture in the relationship, sometimes precipitating the end of the therapy. The study also highlighted the interdependence of the types of interventions and the quality of contact. The author's reflections are also given.     

Mirror neurons and embodied simulation in the development of archetypes and self-agency

Abstract :  In this paper I explore the role of mirror neurons and motor intentionality in the development of self-agency. I suggest that this will also give us a firmer basis for an emergent view of archetypes, as key components in the development trajectory of self-agency, from its foundation in bodily action to its mature expression in mentalization and a conscious awareness of intentionality. I offer some ideas about the implications of these issues of self-agency for our clinical work with patients whose developmental trajectory of self-agency has been partially inhibited, so that their communications have a coercive effect. I discuss the possibility that this kind of clinical phenomenon may relate to Gallese and Lakoff's hypothesis that abstract thought and imagination are forms of simulated action, and that the same sensory-motor circuits that control action also control imagination, concept formation and understanding, but with a crucial development, that of an inhibition of the connections between secondary pre-motor cortical areas and the primary motor cortex. I shall speculate that in the earlier developmental stages of self-agency, the separation of secondary from primary motor areas is not complete, so that imagination and thought are not entirely independent of physical action.
