Transformations in dreaming and characters in the psychoanalytic field1,2

Having reviewed certain similarities and differences between the various psychoanalytic models (historical reconstruction/development of the container and of the mind's metabolic and transformational function; the significance to be attributed to dream‐type material; reality gradients of narrations; tolerability of truth/lies as polar opposites; and the form in which characters are understood in a psychoanalytic session), the author uses clinical material to demonstrate his conception of a session as a virtual reality in which the central operation is transformation in dreaming (de‐construction, de‐concretization, and re‐dreaming), accompanied in particular by the development of this attitude in both patient and analyst as an antidote to the operations of transformation in hallucinosis that bear witness to the failure of the functions of meaning generation. The theoretical roots of this model are traced in the concept of the field and its developments as a constantly expanding oneiric holographic field; in the developments of Bion's ideas (waking dream thought and its derivatives, and the patient as signaller of the movements of the field); and in the contributions of narratology (narrative transformations and the transformations of characters and screenplays). Stress is also laid on the transition from a psychoanalysis directed predominantly towards contents to a psychoanalysis that emphasizes the development of the instruments for dreaming, feeling, and thinking. An extensive case history and a session reported in its entirety are presented so as to convey a living impression of the ongoing process, in the consulting room, of the unsaturated co‐construction of an emotional reality in the throes of continuous transformation. The author also describes the technical implications of this model in terms of forms of interpretation, the countertransference, reveries, and, in particular, how the analyst listens to the patient's communications. The paper ends with an exploration of the concepts of grasping (in the sense of clinging to the known) and casting (in relation to what is as yet undefined but seeking representation and transformation) as a further oscillation of the minds of the analyst and the patient in addition to those familiar from classical psychoanalysis.     

What do we learn from binding features? Evidence for multilevel feature integration

Four experiments were conducted to investigate the relationship between the binding of visual features (as measured by their aftereffects on subsequent binding) and the learning of feature-conjunction probabilities. Both binding and learning effects were obtained, but they did not interact. Interestingly, (shape-color) binding effects disappeared with increasing practice, presumably because of the fact that only 1 of the features involved was relevant to the task. However, this instability was only observed for arbitrary, not highly overlearned combinations of simple geometric features and not for real objects (colored pictures of a banana and strawberry), where binding effects were strong and resistant to practice. These findings suggest that learning has no direct impact on the strength or resistance of bindings or on speed with which features are bound; however, learning does affect the amount of attention particular feature dimensions attract, which again can influence which features are considered in binding.     

Horizontal and vertical Simon effect: different underlying mechanisms?

Reaction times are usually faster when stimulus and response occur at the same location than when they do not, even if stimulus location is irrelevant to the task (Simon effect). This effect was found with both horizontal and vertical stimulus-response arrangements. The same mechanisms have been proposed to be involved in either case. Here, we compared a horizontal and a vertical Simon task by means of a RT time-course analysis of the Simon effect. Also, we analysed the lateralised readiness potential (LRP), an index of covert response-preparation processes. In the horizontal task, the Simon effect decays over time and pre-activation occurs above the motor cortex ipsilateral to the stimulus. In contrast, the Simon effect does not decay over time and no early incorrect LRP deflection is observed in the vertical task. These findings suggest that typical activation accounts can fit only the horizontal Simon effect, while a translation explanation is more suitable for the vertical Simon effect.     

Functional dissociations in temporal preparation: Evidence from dual-task performance

Implicit preparation over time is a complex cognitive capacity important to optimize behavioral responses to a target occurring after a temporal interval, the so-called foreperiod (FP). If the FP occurs randomly and with the same a priori probability, shorter response times are usually observed with longer FPs than with shorter ones (FP effect). Moreover, responses are slower when the preceding FP was longer than the current one (sequential effects). It is still a matter of debate how different processes influence these temporal preparation phenomena. The present study used a dual-task procedure to understand how different processes, along the automatic-controlled continuum, may contribute to these temporal preparation phenomena. Dual-task demands were manipulated in two experiments using a subtraction task during the FP. This secondary task was administered in blocks (Experiment 1) or was embedded together with a baseline single-task in the same experimental session (Experiment 2). The results consistently showed that the size of the FP effect, but not that of sequential effects, is sensitive to dual-task manipulations. This functional dissociation unveils the multi-faceted nature of implicit temporal preparation: while the FP effect is due to a controlled, resource-consuming preparatory mechanism, a more automatic mechanism underlies sequential effects.     

The Case of Online Trust

This paper contributes to the debate on online trust addressing the problem of whether an online environment satisfies the necessary conditions for the emergence of trust. The paper defends the thesis that online environments can foster trust, and it does so in three steps. Firstly, the arguments proposed by the detractors of online trust are presented and analysed. Secondly, it is argued that trust can emerge in uncertain and risky environments and that it is possible to trust online identities when they are diachronic and sufficient data are available to assess their reputation. Finally, a definition of trust as a second-order property of first-order relation is endorsed in order to present a new definition of online trust. According to such a definition, online trust is an occurrence of trust that specifically qualifies the relation of communication ongoing among individuals in digital environments. On the basis of this analysis, the paper concludes by arguing that online trust promotes the emergence of social behaviours rewarding honest and transparent communications.     

The Secret of Faces: Commentary on Paper by Rachael Peltz

Dr. Rachael Peltz stresses the aesthetic dimension of analysis. In fact the aesthetic experience can serve as a model for all that is deepest and truest in our lives and in the analytic encounter. We all have an “inner painter” which transforms primitive sensoriality into images or pictograms and then tie them up into oneiric thoughts, dreaming and thinking in order to give a personal meaning to experience. This model gives us the possibility in the clinical work to be more attentive to the musical, rhythmic, or semiotic aspects of the interaction between patient and analyst. Dr. Peltz shows in a beautiful vignette how, equating analysis to the aesthetic experience, it is possible to help the patient to reach a fuller sense of consonance and contact between mind and body.     

Visual symmetry perception in early onset monocular blindness

Symmetry detection is impaired by abnormal binocular vision development such as in amblyopia. However, the detection of symmetry has never been investigated in cases where input from one eye is profoundly compromised. Testing monocularly blind (MB) individuals represents a unique opportunity to investigate whether symmetry salience relies on a normally developed binocular visual system. In a visual symmetry detection task using dot patterns, congenitally MB showed comparable accuracy to normally sighted individuals viewing monocularly. This included better detection of vertically than horizontally symmetric patterns. However, the MB were slower than controls in detecting a symmetrical pattern. In a control target-detection task, no significant differences in performance were observed between these groups. Overall, normal developing binocular vision does not appear necessary for the visual system to detect the presence of visual symmetry. However, optimal detection mechanisms may be dependent on binocular summation or other processes dependent on input from both eyes.     

Cannabis use and the risk behavior syndrome in Italian university students: are they related to suicide risk?

The aim of this study was to examine the association of cannabis use with risky behaviors and suicide risk in university students. A convenience sample of 246 students was recruited from four universities in Rome during the 2004 academic year. Participants completed the Zung scales for anxiety and depression, the Suicide Score Scale, and an ad hoc questionnaire assessing risky behaviors. The findings indicated a widespread use of cannabis among students and its association with risky behaviors, anxiety and depression, and suicide risk. A regression tree analysis resulted in 3 splits indicating that the Zung Self-Rating Depression Scale is a good predictor of suicide risk, discriminating individuals at lower risk from those at higher risk. Individuals at higher risk for suicide could also be discriminated by self-reported lifetime drug use. Limitations of the study are related to the small sample size and use of a convenience sample.
