Fenomenologia,coscienza del tempo e analisi musicale

This paper explores the relationships between American phenomenology of music and conventional studies of musical analysis. The temporality of experience is a central topic in the phenomenology of music: recent research in USA has focused on musical time-consciousness (Schutz and Smith) or on analytical applications (Clifton, Lochhead, Ferrara). Many methods of musical analysis, like phenomenological methods, are concerned to study subjective temporal structures: Schenkerian and post-Schenkerian scholars (Salzer, Meyer, Narmour, Lewin) have elaborated specific systems for the explanation of musical form on a experiential basis. Apart from any comparison with the different approaches, phenomenological analysis appears to be fundamental for the analytical interpretation of music.     

Influence of Stimulus Salience and Attentional Demands on Visual Search Patterns in Hemispatial Neglect

Seventy-five left and right brain-damaged patients, with or without hemispatial neglect, and 40 age-matched control subjects were tested on cancellation tasks with two different visual textures modeled after Julesz (1981). In one condition (“preattentive”), target elements segregated easily from background elements and were perceived effortlessly. In the other (“attentive”), target elements did not segregate easily and could be detected only after prolonged focal scrutiny. Both controls and patients were more accurate and faster on the preattentive than attentive texture. However, only neglect patients were disproportionately impaired on the attentive texture, thus suggesting that unilateral neglect is exacerbated by the low visual salience of the stimuli and a higher engagement of focal attention. Thus, a simple bedside test may help to tell apart the level of visual information processing maximally impaired in neglect patients.     

Blocked vs. interleaved presentation and proactive interference in episodic memory

Although a number of theoretical accounts of proactive interference (PI) in episodic memory have been proposed, existing empirical evidence does not support conclusively a single view yet. In two experiments we tested the predictions of the temporal discrimination theory of PI against alternative accounts by manipulating the presentation schedule of study materials (lists blocked by category vs. interleaved). In line with the temporal discrimination theory, we observed a clear buildup of (and release from) PI in the blocked condition, in which all the lists of the same category were presented sequentially. In the interleaved condition, with alternating lists of different categories, a more gradual and smoother buildup of PI was observed. When participants were left free to choose their presentation schedule, they spontaneously adopted an interleaved schedule, resulting again in more gradual PI. After longer delays, we observed recency effects at the list level in overall recall and, in the blocked condition, PI-related effects. The overall pattern of findings agrees with the predictions of the temporal discrimination theory of PI, complemented with categorical processing of list items, but not with alternative accounts, shedding light on the dynamics and underpinnings of PI under diverse presentation schedules and over different time scales.     

Long-term meditation: the relationship between cognitive processes,thinking styles and mindfulness

The aim of this study is to examine the relationship between meditation and cognitive functions. More in depth the purpose is to demonstrate that long-term meditation practice improves attention skills and cognitive flexibility. Eighteen long-term meditation practitioners were compared to a matched control group, who never practiced meditation. Each subject was tested, using computerized software (Presentation Software 9.90), which measured: attention, visual search abilities, working memory and Stroop’s interference tasks. Furthermore, we examined the relationship between long-term meditation practice, mindfulness skills and thinking styles, namely styles of processing information. The results showed significant differences between the two groups, demonstrating that long-term meditation is linked to improvements of attentional functions, working memory and cognitive flexibility.     

Diary reports on emotional experiences in the onset of a psychosocial transition: becoming drug‐free

The process of becoming drug free is viewed as a psychosocial transition in the life of drug addicts. A specific form of treatment of heroin addiction within residential communities is based on the importance of interpersonal relationships for change. Well‐being of 65 drug addicts during the first 2 weeks in a residential community is explored using a time‐sampling diary which was completed four times a day. The influence of subjects' history, situational context, and motive activation on well‐being and emotions is investigated. Results show that well‐being and emotions differ mainly according to subjects' history, but not — at least at the beginning of treatment within the community — according to situations. This is interpreted as a ‘state of shock’ in the new environment and highlights the necessity for special individual care for subjects with a long drug career.

Theory and Method of Social Representations

This paper gives an overview of social representation theory, definitions of the key terms and of the social processes leading to a representation and to social identity. Six empirical studies are presented and details of their methods and findings are given to illustrate this social psychological approach. These studies are about the ontogenesis of gender, the public sphere in Brazil, madness on British television, images of androgyny in Switzerland, individualism and democracy in post-communist Europe and metaphorical thinking about conception. The methods are ethnography, interviews, focus-groups, content analysis of media, statistical analysis of word associations, questionnaires and experiments. Finally, social representation theory is compared to theories of attitudes, schemata and social cognition.
