“Conversational” coupling of gaze behavior in prelinguistic human development

Mathematical regularities in the gross temporal pattern of infant-adult gaze behavior are identical to those found in adult verbal conversations. Both types of interaction conform to a Markov chain model. Such regularities suggest some universal property of human communication which predates the onset of speech. The present infants were 3.5 months old.This research was supported by the Grant Foundation, the Research Foundation for Mental Hygiene, Inc., the New York State Department of Mental Hygiene, and the Federal Work-Study program of the City College of New York.     

Introduction to IARPP Plenary Panel,Toronto, June 2015

These brief remarks introduce the symposium on Power and Authority, with clinical material by Francesca Colzani and discussions by Irwin Hoffman, Susanna Federici Nebbiosi, and Gillian Straker. I am glad we have the opportunity in this symposium to discuss power and authority in the clinical situation, because while this subject has been a center of interest for relational psychoanalysts since the inception of the relational perspective, explicit attention has not been paid to the topic in the recent past. Yet power and authority are always present and always important in our activities—in every clinical session, every supervision session, and every page we write. This symposium is composed of an incisive and moving clinical report by Francesca Colzani, followed by discussions by Irwin Hoffman, Susanna Federici Nebbiosi, and Gill Straker.     

Behavioral alterations in mice lacking the translation repressor 4E-BP2

The requirement for de novo protein synthesis during multiple forms of learning, memory and behavior is well-established; however, we are only beginning to uncover the regulatory mechanisms that govern this process. In order to determine how translation initiation is regulated during neuroplasticity we engineered mutant C57Bl/6J mice that lack the translation repressor eukaryotic initiation factor 4E-binding protein 2 (4E-BP2) and have previously demonstrated that 4E-BP2 plays a critical role in hippocampus-dependent synaptic plasticity and memory. Herein, we examined the 4E-BP2 knockout mice in a battery of paradigms to address motor activity and motor skill learning, anxiety and social dominance behaviors, working memory and conditioned taste aversion. We found that the 4E-BP2 knockout mice demonstrated altered activity in the rotating rod test, light/dark exploration test, spontaneous alternation T-maze and conditioned taste aversion test. The information gained from these studies builds a solid foundation for future studies on the specific role of 4E-BP2 in various types of behavior, and for a broader, more detailed examination of the mechanisms of translational control in the brain.     

Individual differences in chess expertise: a psychometric investigation

Starting from controversies over the role of general individual characteristics (especially intelligence) for the attainment of expert performance levels, a comprehensive psychometric investigation of individual differences in chess expertise is presented. A sample of 90 adult tournament chess players of varying playing strengths (1311-2387 ELO) was screened with tests on intelligence and personality variables; in addition, experience in chess play, tournament participation, and practice activities were assessed. Correlation and regression analyses revealed a clear-cut moderate relationship between general (and in particular numerical) intelligence and the participants' playing strengths, suggesting that expert chess play does not stand in isolation from superior mental abilities. The strongest predictor of the attained expertise level, however, was the participants' chess experience which highlights the relevance of long-term engagement for the development of expertise. Among all analysed personality dimensions, only domain-specific performance motivation and emotion expression control incrementally contributed to the prediction of playing strength. In total, measures of chess experience, current tournament activity, intelligence, and personality accounted for about 55% of variance in chess expertise. The present results suggest that individual differences in chess expertise are multifaceted and cannot be reduced to differences in domain experience.     

Constructivism in the Age of Trump: Truth,Lies, and Knowing the Difference

Donald Trump lies so often that some have wondered whether he has poisoned the well. Can we continue to defend the constructivism of relational psychoanalysis, with its emphasis on interpretive understanding? Might it not be claimed that this is actually the very approach Trump himself takes? Does an openness to interpretive understanding allow anybody to just say anything, as Trump does? Would our views perhaps be more justified and defensible, and give less shelter to the world’s liars, if we shifted to a reliance on objectivism and its advocacy of “facts?” I say no. I take the point of view, drawing illustrations from the news of the months just before this presentation was delivered (June 2018), that the crucial democratic influence of constructivism not only persists when despotic leaders lie in order to enforce their agendas, it is actually magnified under circumstances like those we face now.
