Updating and inhibition processes in working memory: a comparison between Alzheimer's type dementia and frontal lobe focal damage

A large debate has recently focused on the componential nature of the working-memory system (), as evidenced by functional-imaging studies and by using more sophisticated experimental paradigms. The present work aims at further disentangling the role and effects of central executive (CE) and of phonological loop (PL). It is suggested that maintaining active verbal information mostly relates to an intact PL, while the inhibition of interfering information preponderantly involves the CE. To distinguish these effects, two groups of brain damaged patients were administered with an updating task. Frontal lobe patients showed major difficulties in inhibiting interfering information, an ability requiring an involvement of the CE component. In contrast, Alzheimer's dementia patients evidenced a relative impairment in maintaining relevant information, requiring the intervention of the PL.     

A new scale for the assessment of the quality of hospitality services

In the last 20 years the services sector has experienced a highly significant growth, being currently one of the most important economic sectors in our country. Inside the touristic sector, a strong competence has being experienced among the lodging and restoration establishments. In a scenario characterized by competitiveness, the bet for quality represents a difficult competitive advantage to surpass (García-Buedes, 2001). The objective of this study is to carry out an approach to the evaluation of the perceived quality of the restaurants. As a result of bibliographic revision, and also a first approach of a qualitative nature, we started from a scale of 31 items that included 5 dimensions: access, personal, service, product and installations. The results obtained applying the questionnaire to more than 2400 clients of 180 establishments of Santiago de Compostela and region, by means of structured interviews, confirmed that not all these dimensions had the same importance as predictors of customer satisfaction. Specifically, the product emerges as the most important dimension. Likewise, the elimination of the dimension service and a more exhaustive selection of the items, based on psychometric criteria, has permitted to define a brief scale, consisting of only 15 items, which makes it very attractive as a management tool. The final scale proposed to evaluate the perceived quality in the restaurant sector includes four fundamental and non-independent dimensions. These are, ordered by importance: product, personal, installations and access.     

Age-related Differences in the Production of Textual Descriptions

Narratives produced by 69 healthy Italian adults were analyzed for age-related changes of microlinguistic, macrolinguistic and informative aspects. The participants were divided into five age groups (20-24, 25-39, 40-59, 60-74, 75-84). One single-picture stimulus and two cartoon sequences were used to elicit three stories per subject. Age-related differences were found with respect to semantic paraphasias, paragrammatisms, syntactic complexity, degree of both local and global coherence, local coherence errors (like ambiguous referencing), and in the level of informativeness conveyed by the stories. The results showed some null effects of age, some effects with a sharp drop in performance in the oldest group, and several effects suggesting a gradual decrease in performance across age groups. No age differences were found with respect to phonological selection and noun-verb ratio. In the proportion of details vs. main themes, the results indicated a possibly better story construction ability in the middle aged (40-59) and young elderly (60-74) groups compared to the younger or the oldest group. Story-type (single picture vs. picture sequence) had a significant influence on some macrolinguistic and informativeness measures.     

Holism, Strawberries and Hairdryers

The paper "Does Epistemological Holism lead to Meaning – Holism" (Cozzo, 2002) touches one of the main problems of a molecularist theory of meaning: how to restrict the class of inferences connected with a word, in order to define the sense of the word. I will discuss the starting point of this approach, mainly the pre-theoretical criterion against meaning holism: meaning holism, following a well-known argument by Dummett, reduces communication to a mystery. However there is a strong background assumption of this argument: communication is sharing the same meanings. Accepting this assumption without acknowledging it makes the entire proposal more problematic than it appears at first sight. In what follows I will try to clarify the possibility of a different reaction to meaning holism, putting forward some distinctions which come to light when the above stated assumption is made explicit. Then, some other comments will follow on the difficulty of avoiding extreme meaning holism, even within Cozzo's elegant attempt to implement a molecularist vision; in the end, his notion of the sense of a word will appear to be difficult to define, if these holistic aspects of language take the space they deserve even in his theory. I conclude with two remarks regarding two relevant requirements for a theory of meaning (conservativeness and harmony).

Dominance of global visual properties at birth

Six experiments are reported that were aimed at demonstrating the presence in newborns of a perceptual dominance of global over local visual information in hierarchical patterns, similar to that observed in adults (D. Navon, 1977, 1981). The first four experiments showed that, even though both levels of visual information were detectable by the newborn (Experiments 1A and 1B), global cues enjoyed some advantage over local cues (Experiments 2 and 3). Experiments 4A and 4B demonstrated that the global bias was strictly dependent on the low spatial frequency content of the stimuli and vanished after selective removal of low spatial frequencies. The results are interpreted as suggesting parallels between newborns' visual processing and processing later in development.     

white supremacist behavior: toward an integrated social psychological model

The literature conceptually exploring the deviant behavior of white supremacists is somewhat limited. Those contributions that do exist tend to be more disciplinary specific, anchored in sociological, psychological, or criminological research. One approach to organizing the extant literature comes from social psychology. This domain allows for considerably more disciplinary cross-fertilization. The present study examines the behavior of white supremacists utilizing a social psychological model. The model emphasizes the intrapsychic, the interpersonal, and the situational dynamics at work in the daily practices of white supremacists. In order to assess how these prisms operate, four thematic categories, essential to the organization of white supremacists, are systematically investigated. These categories include the role of power, identity, sexuality, and the de nition of the situation. We contend that our social psychological approach represents something of an integrated model for understanding the deviant attitudes, thought processes, and ritualized activities of white supremacists. We conclude by suggesting that the proposed interpretive schema may have utility in other, similar areas of social scientific inquiry.     

theorizing non-linear communities: on social deviance and housing the homeless

Theories of deviance abound; however, little attention has been given to the construction and meaning of deviance in postmodern society. According to some theorists, one conceptual variant of postmodernism is chaology or non-linear dynamical systems theory. In this article, the relevance of chaos theory for advancing our understanding of social deviance is examined. In particular, such notions as non-linearity, fractal space, attractors, self-similarity, bifurcations, and dissipative structures are described as constitutive of the postmodern agenda. These insights are then applied to the difficult and complex issue of housing the homeless, especially shelter strategies designed to create personhood and place for the poor and disenfranchised.     

High cost helping scenario: The role of empathy,prosocial reasoning and moral disengagement on helping behavior

This study aimed to investigate the process that leads people to offer or omit help in response to an explicit request for assistance, taking into account both emotional and cognitive factors. Specifically, a hypothetical scenario methodology was used in a sample of 174 Italian youths (50% males) to examine whether and how factors such as empathy, prosocial moral reasoning and moral disengagement influence the propensity to help when providing assistance is not in the individual’s personal interest. While a few previous studies have included moral disengagement as an antecedent of prosocial decision making, we highlight the significance of this factor in the avoidance of moral responsibility towards others in need. The results highlight two ways in which differences in emotional tendencies and moral-cognitive processes may operate in prosocial decision making in high personal cost situations. First, high empathy levels could promote an altruistic response which in turn fosters mature prosocial moral reasoning. Second, personal distress may enhance moral disengagement mechanisms that may facilitate self-centred behaviors.     

The return of the Sophists

The author argues against a foundational epistemology and thus sides with the Greek Sophists. He shows that the search for foundations of knowledge and truth is the outcome of a referential theory of language. He finds that Nietzsche and Saussure pioneered attacks on and substitutions for this theory. Wittgenstein, Derrida and Rorty, inter alia, continued this trend. The author discusses the criticisms and theories of these philosophers and finds that he agrees with their criticisms and many of their positive moves but that he cannot accept their social relativism because it cannot account for inter- and transcultural understanding and the regulative role of truth. He looks for a theory of language and truth which will also comply with these requirements.     

Between Symbol and Antisymbol - The Meaning of Trauma Reconsidered

Within psychoanalysis, it has usually been assumed that what makes an external event traumatic is the personal meaning of the event for that individual, i.e. how it resonates within his/her internal world and in relation to the infantile conflict. Such an assumption, which implies that a trauma operates as a symbol, is compared with the contrasting view that a trauma rather destroys the capacity of symbolization, and discussed in relation to the psyche-soma issue. It is finally maintained that psychic trauma forces upon the victim a vast and difficult transformation, in relation to which the body can be used as an antisymbolic device to resist mental change.
