Stereotypes in Persuasive Communication: Influence Exerted by a Disapproved Source

The present paper examines how someone's use of stereotypes can exert influence over others' judgments. In the 2 studies reported here, participants were presented with messages containing information provided by a source. In Study 1, the source was an in-group member. The messages were manipulated in a between-subjects design so that participants were either given stereotypical or counterstereotypical information. After being given a hint regarding the source's estimate, participants were asked to provide their own estimates about a number of points displayed on a computer screen. Results indicate that participants tended to use as an anchor the estimate provided by the source that made use of stereotypes. In Study 2, an out-group member provided participants with information that was either stereotypical or neutral. Again, results indicate that participants were influenced by the source making use of stereotypes.     

On the Concept of Psychological

The idea that certain mental phenomena (e.g. emotions, depression, anxiety) can represent risk factors for certain somatic diseases runs through common thinking on the subject and through a large part of biomedical science. This idea still lies at the focus of the research tradition in psychosomatic medicine and in certain interdisciplinary approaches that followed it, such as psychoneuroimmunology. Nevertheless, the inclusion in the scientific literature of specifically mental phenomena in the list of risk factors pertaining to a specific pathological condition would seem, to say the least, problematic when not completely absent, unlike what happens for certain behavioural factors, such as smoking, sedentary life, and alcohol abuse. It is also significant that insurance companies and health and welfare services do not pay for interventions and treatment for states of anxiety, disorders of mood and of the personality, alexithymia and stress reduction, as means of prevention or treatment of somatic diseases, as instead they do for the treatment of tobacco addiction. However, as I shall endeavour to argue here, there are numerous and well grounded reasons why this different consideration of psychic conditions compared with behaviours is valid and must be maintained in the evaluation of pathogenetic risk factors.     

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.     

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.     

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.     

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.     

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.
