Consequences of violating the assumption of independence in the process dissociation procedure: A word fragment completion study

In three experiments that used levels of processing and study time manipulations as independent variables in a word fragment completion task, the validity of the assumption of independence between recollection and automatic influences of memory was assessed. This assumption underlies the use of the process dissociation procedure (Jacoby, 1991), a tool suggested for distinguishing the different contributions of recollection and automatic influences of memory. Overall, it appeared that semantic processing, as compared with physical processing at study, positively affected recollection but negatively affected automatic influences of memory in word fragment completion. This negative effect on the automatic influences was reduced when the available study time decreased. The incompatibility of these results with the assumption of independence between recollection and automatic influences of memory and their impact on the applicability of the process dissociation procedure are discussed.     

Investigating Conversational Dynamics: Interactive Alignment,Interpersonal Synergy,and Collective Task Performance

This study investigates interpersonal processes underlying dialog by comparing two approaches, interactive alignment and interpersonal synergy, and assesses how they predict collective performance in a joint task. While the interactive alignment approach highlights imitative patterns between interlocutors, the synergy approach points to structural organization at the level of the interaction—such as complementary patterns straddling speech turns and interlocutors. We develop a general, quantitative method to assess lexical, prosodic, and speech/pause patterns related to the two approaches and their impact on collective performance in a corpus of task‐oriented conversations. The results show statistical presence of patterns relevant for both approaches. However, synergetic aspects of dialog provide the best statistical predictors of collective performance and adding aspects of the alignment approach does not improve the model. This suggests that structural organization at the level of the interaction plays a crucial role in task‐oriented conversations, possibly constraining and integrating processes related to alignment.     

Cross-modal and intra-modal binding between identity and location in spatial working memory: The identity of objects does not help recalling their locations

In this study we tested incidental feature-to-location binding in a spatial task, both in unimodal and cross-modal conditions. In Experiment 1 we administered a computerised version of the Corsi Block-Tapping Task (CBTT) in three different conditions: the first one analogous to the original CBTT test; the second one in which locations were associated with unfamiliar images; the third one in which locations were associated with non-verbal sounds. Results showed no effect on performance by the addition of identity information. In Experiment 2, locations on the screen were associated with pitched sounds in two different conditions: one in which different pitches were randomly associated with locations and the other in which pitches were assigned to match the vertical position of the CBTT squares congruently with their frequencies. In Experiment 2 we found marginal evidence of a pitch facilitation effect in the spatial memory task. We ran a third experiment to test the same conditions of Experiment 2 with a within-subject design. Results of Experiment 3 did not confirm the pitch–location facilitation effect. We concluded that the identity of objects does not affect recalling their locations. We discuss our results within the framework of the debate about the mechanisms of “what” and “where” feature binding in working memory.     

PRIMITIVE MENTAL STATES AND THE BODY: A PERSONAL VIEW OF ARMANDO B. FERRARI'S CONCRETE ORIGINAL OBJECT

The author explores some psychoanalytic hypotheses about primitive mental states and their implications for a direct focus on body experience in clinical work. Some aspects of current clinical research about the patient's difficulty in achieving awareness of his emotional life as it emerges from object relations are presented, and this problem is viewed in connection with the relation of the analysand to his own body and to his capacity to pass through the different levels of mental elaboration, from motor discharge to abstraction. Ferrari's theories on the body—mind relationship are discussed and compared with the work of other authors. Ferrari calls the body the Concrete Original Object to indicate that it is the first source, differing from person to person, from which mental phenomena are generated and against which they are constantly measured. A clinical case serves as an illustration of the importance of the perception of the body for the birth of genuine, non-imitative mental activity.     

The logic of turmoil: some epistemological and clinical considerations on emotional experience and the infinite

The idea of the infinite has its origins in the very beginnings of western philosophy and was developed significantly by modern philosophers such as Galileo and Leibniz. Freud discovered the Unconscious which does not respect the laws of classical logic, flouting its fundamental principle of non-contradiction. This opened the way to a new epistemology in which classical logic coexists with an aberrant logic of infinite affects. Matte Blanco reorganized this Freudian revolution in logic and introduced the concept of bi-logic, which is an intermingling of symmetric and Aristotelic logics. The authors explore some epistemological and clinical aspects of the functioning of the deep unconscious where the emergence of infinity threatens to overwhelm the containing function of thought, connecting this topic to some of Bion's propositions. They then suggest that bodily experiences can be considered a prime source of the logic of turmoil, and link a psychoanalytic consideration of the infinite to the mind-body relation. Emotional catastrophe is seen both as a defect-a breakdown of the unfolding function which translates unconscious material into conscious experience-and as the consequence of affective bodily pressures. These pressures function in turn as symmetrizing or infinitizing operators. Two clinical vignettes are presented to exemplify the hypotheses.     

Does the use of mobile phones affect human short‐term memory or attention?

The effect of acute exposure to low‐level radio frequency electromagnetic fields (REF) generated by mobile phones on short‐term memory and attention was assessed in two experiments. Most of the tests manipulated task difficulty or what might be termed cognitive load. This manipulation is important since previous studies have argued that exposure to mobile phones might affect cognitive functions only under conditions which tax the cognitive system. All participants were exposed to REF (half were exposed to GSM—Global System for Mobile Communication—signals and the other half were exposed to unmodulated signals) in one testing session, while in a separate session participants were exposed to sham signals. To investigate potential lateralised effects, the mobile phone was positioned on the left side of the head for half of the participants and on the right side for the other half. No significant effect of exposure to REF was detected in any of the six tasks used in either the low or high cognitive load conditions. This study used much larger sample sizes than is typical for this type of research and REF exposure was administered under double‐blind conditions. Overall, the results indicate that acute exposure to REFs emitted by mobile phones do not have a strong impact on cognitive functions. Copyright © 2007 John Wiley & Sons, Ltd.     

How to accurately detect autobiographical events

ABSTRACT— We describe a new method, based on indirect measures of implicit autobiographical memory, that allows evaluation of which of two contrasting autobiographical events (e.g., crimes) is true for a given individual. Participants were requested to classify sentences describing possible autobiographical events by pressing one of two response keys. Responses were faster when sentences related to truly autobiographical events shared the same response key with other sentences reporting true events and slower when sentences related to truly autobiographical events shared the same response key with sentences reporting false events. This method has possible application in forensic settings and as a lie-detection technique.     

The case of Dr. Jekyll and Mr. Hyde: a kinematic study on social intention

The aim of the present study was to investigate the effects of social intentions on action. Participants (N=13) were requested to reach towards, grasp an object, and either pass it to another person (social condition) or put it on a concave base (single-agent condition). Movements' kinematics was recorded using a three-dimensional motion analysis system. The results indicate that kinematics is sensitive to social intention. Movements performed for the 'social' condition were characterized by a kinematic pattern which differed from those obtained for the 'single-agent' condition. Results are discussed in terms of a motor simulation hypothesis, which assumes that the same mechanisms underlying motor intention are sensitive to social intentions.

Flexibility of the Psychoanalytic Approach in the Treatment of a Suicidal Patient: Stubborn Silences as “Playing Dead”

The author presents the clinical case of a patient in his third analysis who seemed emotionless, did not feel alive, and complained of an uncontrollable urge to gamble, with disastrous financial results. His previous four-session-a-week “orthodox” analysis had left him prey to a sense of emptiness and to intense suicidal urges. He wanted only two weekly sessions, which became three after some analytic work. The author stresses the danger of rigidly following inflexible standards and the consequent activation of a pseudo-compliance in the analysand. A more slowly paced psychoanalysis should not be considered lower in the pecking order than “high-frequency” treatment, the author maintains: It requires great creative subjective involvement on the part of the analyst and close interaction in the context of the analytic couple. The author shows how this analysis involved a series of interactions in which the analyst was called upon to exercise a complex responsiveness, attuned in each instance to the patient's current needs. Finally he focuses on some clinical passages to show how the patient's internal theories represent a glaring assault on common sense and how death was not recognized perceptionally on a realistic level, but was instead replaced with acting out death against himself by keeping himself mentally dead and by suicidal urges.
