THE ANALYST AT WORK: TWO SESSIONS WITH ALBA

In this paper, the author presents clinical material that relates to two sessions with a patient called Alba. This analytic work, being of a somewhat unusual character, lends itself to discussion, the author feels, since the technical choices made are undoubtedly very personal and he believes many colleagues might have done things differently. The author endeavours to enrich the account of the sessions with his concomitant thoughts, so as to supply colleagues with the elements, atmosphere and developments of his internal workshop.     

Explaining Consumer Conduct: From Planned to Self‐Expressive Behavior1

Within mainstream social psychology, consumer behavior has been explained mainly in terms of the theory of planned behavior (TPB). Recently, some authors suggested that self‐identity dimensions can explain different types of intentions. To compare the predictive power of a tentative new model of self‐expressive consumer behavior with that of the TPB, three studies were conducted in which, besides the classical variables of the model of TPB, variables concerning self‐identity were also taken into account. Three independent samples (N₁= 257, N₂= 214, N₃= 298) were recruited to study the intention to buy fashionable watches, trendy backpacks, and cellular telephones in relation to the aforementioned variables derived from TPB and from identity theory. Data analyses, based on structural equation modeling, show that identity variables contribute significantly to the explanation of purchase intention.     

A Temporal Semantics for Basic Logic

In the context of truth-functional propositional many-valued logics, Hájek’s Basic Fuzzy Logic BL [14] plays a major rôle. The completeness theorem proved in [7] shows that BL is the logic of all continuous t-norms and their residua. This result, however, does not directly yield any meaningful interpretation of the truth values in BL per se. In an attempt to address this issue, in this paper we introduce a complete temporal semantics for BL. Specifically, we show that BL formulas can be interpreted as modal formulas over a flow of time, where the logic of each instant is ?ukasiewicz, with a finite or infinite number of truth values. As a main result, we obtain validity with respect to all flows of times that are non-branching to the future, and completeness with respect to all finite linear flows of time, or to an appropriate single infinite linear flow of time. It may be argued that this reduces the problem of establishing a meaningful interpretation of the truth values in BL logic to the analogous problem for ?ukasiewicz logic.     

A psychobiographical analysis of Brian Douglas Wilson: Creativity, drugs, and models of schizophrenic and affective disorders

The suggestion of a relationship between creativity and mental disorder has existed for centuries, and has been advocated by many psychological researchers. The present analysis offers a consideration of the nature of mental disorder present in Brian Wilson, an individual recognised as one of the most creative figures in 20th century popular music. Using converging biographical evidence, and the diagnostic program Opcrit, Wilson’s diagnosis is concluded to be schizoaffective. Employing details of his drug abuse, various models of schizoaffective spectra are examined, in particular a reconsideration of the LSD model of schizophrenia. The model is shown to be useful for positive schizophrenic symptoms including overinclusion, a potentially key element of creativity. In doing so, this psychobiographical analysis allows examination of potential relationships between mental disorder and creativity, the effects of various narcotics on creativity and various elements of mental disorder, the efficacy of various drug models of psychotic disorders, and the overlap between psychotic and affective disorders.     

Plant neurobiology: from sensory biology,via plant communication,to social plant behavior

In plants, numerous parameters of both biotic and abiotic environments are continuously monitored. Specialized cells are evolutionary-optimized for effective translation of sensory input into developmental and motoric output. Importantly, diverse physical forces, influences, and insults induce immediate electric responses in plants. Recent advances in plant cell biology, molecular biology, and sensory ecology will be discussed in the framework of recently initiated new discipline of plant sciences, namely plant neurobiology.     

The breakdown of semantic knowledge: insights from a statistical model of meaning representation

Investigations of patients with semantic category-specific deficits have revealed a wide range of performance and variability in categories that are impaired or spared; this variability presents a challenge to accounts of category specificity. Accounts based only on impairment to semantic features of a particular type (e.g., visual), as well as accounts based only on featural properties (e.g., feature intercorrelations), are insufficient to explain the variability of patients' performance. A first goal of the paper is to discuss how a hybrid account incorporating both a level of organization according to feature types (a level of nonlinguistic conceptual representations) and a level of organization dictated by featural properties may provide a more comprehensive account of the cases reported in the literature. The second and most novel goal of the study reported here is to derive from our hybrid account a series of novel predictions concerning the representation and impairment of a different domain of knowledge: knowledge of actions and events, a domain of knowledge that has received remarkably little attention to date.     

Visual interaction: models, systems, prototypes. The Pictorial Computing Laboratory at the University of Rome “La Sapienza”

This paper reports on the research activities performed by the Pictorial Computing Laboratory at the University of Rome, La Sapienza, during the last 5 years. Such work, essentially is based on the study of humancomputer interaction, spans from metamodels of interaction down to prototypes of interactive systems for both synchronous multimedia communication and groupwork, annotation systems for web pages, also encompassing theoretical and practical issues of visual languages and environments also including pattern recognition algorithms. Some applications are also considered like e-learning and collaborative work.     

Does Arguing from Coherence Make Sense?

In this paper the argument from coherence is submitted to a critical analysis. First, it is argued to be a complex form of coordinative argumentation, structured on various argumentative levels. Then, using the pragma-dialectical theory of argumentation a distinction is brought out between two basic forms of the argument from coherence: in one use this argument occurs as a sequence of two symptomatic arguments; in the other use we have a main symptomatic argument supported by a subordinate pragmatic argument. Finally, from an evaluative point of view it is assessed whether the argument from coherence can be found acceptable as a tool for settling disputes. It is claimed that in general, we can welcome this argumentative structure as sound and fully acceptable provided that we are aware of the interpretative discretion its use implies. A preliminary version of this essay was presented at the symposium organised by the Department of Speech Communication, Argumentation Theory, and Rhetoric at the University of Amsterdamon the 27/02/04. I wish to express my indebtedness to Dora Achourioti, Francesco Belvisi, Frans van Eemeren, Eveline Feteris, Bart Garssen, Jean Wagemans, Peter Houtlosser, and Henrike Jansen for their helpful remarks. Needless to say, the responsibility for the views expressed herein as well as for any errors of form or content rests solely with me.     

Self-awareness,Perspective-taking,and Egocentrism

The present experiment examined the effect of self-awareness on adult perspective-taking and egocentrism. After having indicated their own opinion on an ecology-related topic, university students estimated a fellow student’s opinion on the same matter. Participants did so either in front of a mirror or not, and either after having received a cue for the fellow student’s most probable opinion—his perspective—or not, resulting in a 2 (self-awareness: Low vs. high) × 2 (cue: Yes vs. no) between persons design. As expected, self-aware participants were more likely to correctly estimate the fellow student’s most probable opinion, reflecting perspective-taking, if a cue for his/her perspective was provided. Moreover, self-awareness also reduced participants’ false consensus beliefs (i.e., egocentrism)—when they had a cue for the fellow student’s perspective. The results conceptually replicate and extend previous findings on self-awareness, perspective-taking, and egocentrism.
