The relationship between maladaptive personality functioning and problematic technology use in adolescence: A cluster analysis approach

In the last two decades, scientific research has explored the problematic use of internet, videogames and mobile phones. However, there is still little consistent knowledge regarding the co-occurrence of problematic technology use and the role of maladaptive personality characteristics in adolescence. The present study aimed to investigate adolescents' styles of technology use with a cluster analysis approach focusing on personality functioning. The sample comprised 408 Italian adolescents (46.3% males) aged 11 to 18 years (M _age = 13.80; SD = 2.08). Data were collected using the Internet Addiction Test, the Videogame Dependency Scale, the Test of Mobile-Phone Dependence Brief Form and the Personality Inventory for DSM5 Brief Form. Results provided a four-cluster solution based on the co-occurrence of problematic technology use. The four clusters were labeled as follows: cluster 1: “Above average internet and mobile-phone use”; cluster 2: “Below average technology use”; cluster 3: “Above average videogame use”; and cluster 4: “Problematic technology use.” Analyses on demographic variables (e.g., gender and age) demonstrated significant differences between the four groups. Adolescents with high levels of problematic technology use reported greater overall personality dysfunction than the other three groups. This finding supported our hypothesis on maladaptive personality functioning in adolescents at risk for addiction. Finally, the Antagonism domain played a specific role in differentiating the severity of adolescents' involvement in technology use. Further studies are needed to confirm our findings and to plan preventive interventions as well as therapeutic treatments.     

Immersion versus interactivity and analytic field

Losing oneself in a story, a film or a picture is nothing but another step in the suspension of disbelief that permits one to become immersed in the 'novel' of reality. It is not by chance that the text-world metaphor informs classical aesthetics that, more than anything else, emphasizes emotional involvement. On the contrary, as in much of modern art, self-reflexivity and metafictional attention to the rhetoric of the real, to the framework, to the conventions and to the processes of meaning production, all involve a disenchanted, detached and sceptic vision--in short, an aesthetics of the text as game. By analogy, any analytic style or model that aims to produce a transformative experience must satisfactorily resolve the conflict between immersion (the analyst's emotional participation and sticking to the dreamlike or fictional climate of the session, dreaming knowing it's a dream) and interactivity (for the most part, interpretation as an anti-immersive device that 'wakes' one from fiction and demystifies consciousness). In analytic field theory the setting can be defined--because of the weight given to performativity of language, to the sensory matrix of the transference and the transparency of the medium--the place where an ideal balance is sought between immersion and interaction.     

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.     

Group processes in food choices: The role of ethnic identity and perceived ethnic norms upon intentions to purchase ethnical food products

A study tested an extended Theory of Planned Behaviour (TPB) model, inclusive of measures of ethnical identification and perceived ethnic group norms, in the ethnical food purchasing domain. One hundred and thirty‐five Jamaicans, living in the Brixton neighbourhood, London, were administered a self‐reported questionnaire measuring the classical TPB components (attitudes, subjective norms, perceived behavioural control, behavioural intentions) plus three additional components: identification with the Jamaican group, perceived norms of the Jamaican group and past behaviour. Results of hierarchical multiple regressions showed that past behaviour, ethnical identification and perceived group norms explain an additional proportion of variance in intentions, independently of attitudes, subjective norms and perceived control. A two‐way interaction, between ethnical identification and perceived group norms, was detected. A stronger relation between group norms and intentions emerged among high ethnical identifiers. Theoretical and practical implications are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Affective interactions using virtual reality: the link between presence and emotions.

Many studies showed the ability of movies and imagery techniques to elicit emotions. Nevertheless, it is less clear how to manipulate the content of interactive media to induce specific emotional responses. In particular, this is true for the emerging medium virtual reality (VR), whose main feature is the ability to induce a feeling of "presence" in the computer-generated world experienced by the user. The main goal of this study was to analyze the possible use of VR as an affective medium. Within this general goal, the study also analyzed the relationship between presence and emotions. The results confirmed the efficacy of VR as affective medium: the interaction with "anxious" and "relaxing" virtual environments produced anxiety and relaxation. The data also showed a circular interaction between presence and emotions: on one side, the feeling of presence was greater in the "emotional" environments; on the other side, the emotional state was influenced by the level of presence. The significance of these results for the assessment of affective interaction is discussed.     

Rhetorical Argumentation in Italian Academic Discourse

The recent trend in institutional communication research seems to foster the image of the University as a private organization significantly oriented towards a policy of customer satisfaction. Following the concept of organizational culture, institutional settings too are conceived as organizational contexts, where discourse is a privileged vehicle to convey and spread values, traditions and artifacts, both through internal and external communication practices. Thus, within academic discourse organizational culture is shaped and perpetuated by specific devices of rhetorical argumentation. The corpus of data consists of two different examples of academic discourse: the self promotional endorsement letters of the academic candidates to the chancellor’s position on occasion of the elections and the inaugural speeches proclaimed by the chancellors in charge during the opening celebration of the academic year. The first kind of academic discourse could be meant as an example of political discourse since the candidates use communication strategically and manipulate their academic membership as a rhetorical device to support their aims. On the other hand, the second example is a mere celebration of academic culture which through linguistic rituals recalls and perpetuates the basic values of this microcosm. The data have been analysed with the critical discourse analysis and diatextual analysis which pay particular attention to the context of speech. Moreover, attention has been focused on the metaphors and on the meta-discursive cues. The results show that although with different purposes academic discourse use similar discursive and rhetorical strategies as both belong to the same organization.     

Personality functioning in patients with a progressive course of multiple sclerosis

This study intended to describe general personality functioning in patients with a progressive course of multiple sclerosis. 55 consecutive rehabilitation inpatients with progressive course of multiple sclerosis were assessed with a multimethod test battery: the Expanded Disability Status Scale, the Beck Depression Inventory, the State-Trait Anxiety Inventory, the Rosenberg Self-esteem Scale, and the Rorschach Test administered and scored with Comprehensive System. The control group comprised 55 healthy participants with similar sociodemographic characteristics. Specific differences were found for both cognitive and affective aspects, as the patients with progressive course of multiple sclerosis had less positive self-image, less effective mediation processing, and an affective approach to reality. Present data illustrated the usefulness of examining patients with a progressive course of multiple sclerosis to identify abilities and difficulties in cognitive and affective patterns, and support better adaptation to relationships and the environment.
