BDNF serum levels in subjects developing or not post-traumatic stress disorder after trauma exposure

Post-traumatic stress disorder (PTSD) is a syndrome resulting from exposure to a severe traumatic event that poses threatened death or injury and produces intense fear and helplessness. The neural structures implicated in PTSD development belong to the limbic system, an important region for emotional processing. Brain-derived neurotrophic factor (BDNF) is a neurotrophin that serves as survival factor for selected populations of central nervous system (CNS) neurons and plays a role in the limbic system by regulating synaptic plasticity, memory processes and behavior. Impaired BDNF production in the brain can lead to a variety of CNS dysfunctions including symptoms associated with PTSD. However, so far fewer studies have investigated this neurotrophin in patients with PTSD. Furthermore, given the multiple role of BDNF in various CNS disorders, it cannot be excluded that traumatic events per se may influence neurotrophin levels, without a direct association to the PTSD syndrome.     

The scientific turn in metaphysics: a factualist approach

In a recent paper, Cumpa (Am Philos Q 51(4): 319–324, 2014) argues that a scientific turn in metaphysics requires the acceptance of a materialist criterion of fundamentality, according to which the most fundamental metaphysical category is the one that provides us with a reconciliation of the ordinary world and the physical universe. He concludes that the dominant category of substance cannot be the most fundamental category, for it does not satisfy this criterion of fundamentality. The most fundamental category is instead the category of fact. Although convincing, the defense of factualism over substantialism offered by Cumpa takes into account the case of classical physics without considering the physical universe of quantum mechanics. My aim in this paper is to offer a completion to Cumpa’s factualist approach. To achieve my aim, I show that substances cannot provide a satisfactory account of the relationship between the ordinary world and the physical universe even in the case of quantum mechanics, whereas a factualist approach does.

     

Assessing the automaticity of the exogenous orienting of tactile attention

We examined whether or not abrupt tactile onsets are capable of exogenously capturing tactile spatial attention when visual spatial attention is focused elsewhere. In experiment 1, we compared performance under dual-task conditions (where participants performed a tactile exogenous cuing task and a rapid serial visual presentation--RSVP--task at the same time) with their performance under single-task conditions (where the participants had to perform only the cuing task, although the RSVP stream was still presented in the background) and to a no-stream condition (where only the cuing task was presented). Tactile cuing was completely suppressed in both the dual-task and single-task conditions, showing that exogenous tactile spatial orienting is modulated by visual-spatial attention, which hence appears to be far from truly automatic. In experiment 2, we demonstrated that the abolishment of exogenous tactile orienting was not caused by the transient presentation of abrupt onset stimuli (letters). These results therefore show that exogenous spatial attentional orienting toward abrupt peripheral tactile stimuli is possible as long as perceptual resources are not depleted by a perceptually demanding (RSVP) task.     

De-polarizing verbal irony

In three studies participants were asked to rate the degree of irony perceived in comments relating to five variations of a scenario, ranging from one pole to the opposite pole and passing through three in-between states. In study 1, the comments pertained to the polar extremes of a dimension, e.g. “It’s uphill!” stated with reference to varying degrees of steepness both uphill and downhill (i.e. steep, slightly steep, flat, slightly sloping downhill and steeply sloping downhill). In study 2, the comments were of an “intermediate” nature (e.g. “This hill is neither uphill nor downhill!”) and, as in Study 1, they were used to refer to the same five varying degrees of the same dimension. Study 3 involved the stimuli from both of the first two experiments in a between-participants design.

The results consistently demonstrated that verbal irony does not only apply to (weakly or strongly) polarised statements and situations, but it can also apply to intermediate comments and experiences. The perceptual structure of the dimensions involved modulates the effect.     

New perspectives in assessing deception: The evolution of the truth machine

In recent years a growing interest has arisen in the development of tools for the detection of deception. Since William M. Marston's first publication (1917) on the use of the polygraph as a lie detector, the application of this tool, commonly known as the truth machine, has evolved. Modern technologies are now trying to push the issue further, investigating brain activity during deception using functional Magnetic Resonance Imaging (fMRI). The aim of this paper is to summarise the evolution of research from the original use of the polygraph to the use of new technologies in detecting deception, in order to provide an overview of the recent developments on the use of measurements of deception, and promote new research in this highly important domain of applied cognitive psychology.     

The suppression of reflexive visual and auditory orienting when attention is otherwise engaged

Two experiments were conducted to examine whether abrupt onsets are capable of reflexively capturing attention when they occur outside the current focus of spatial attention, as would be expected if exogenous orienting operates in a truly automatic fashion. The authors established a highly focused attentional state by means of the central presentation of a stream of visual or auditory characters, which participants sometimes had to monitor. No intramodal reflexive cuing effects were observed in either audition or vision when participants performed either an exogenous visual or auditory orthogonal cuing task together with the central focused attention task. These results suggest that reflexive unimodal orienting is not truly automatic. The fact that cuing effects were eliminated under both unimodal and cross-modal conditions is consistent with the view that auditory and visual reflexive spatial orienting are controlled by a common underlying neural substrate.     

Owning Mindfulness: A Bibliometric Analysis of Mindfulness Literature Trends Within and Outside of Buddhist Contexts

The mindfulness literature, now extended beyond strict Buddhist and psychotherapeutic contexts, has trended in some important directions, giving rise to both conflict and opportunity. In terms of mindfulness-directed effort, which academic disciplines are outpacing which? Has the degree of disembeddedness from Buddhist contexts changed over time? What is the relationship between trends in mindfulness, meditation, and Buddhism-oriented literature? Through a bibliometric analysis of mindfulness literature within academic journals, several patterns emerge. Results support a substantial increase in ‘academic effort’ toward mindfulness, crossing a number of disciplines, independent of increased publications concerning meditation, Buddhism, or in these fields at large. While the psychological disciplines have dominated mindfulness literature for several decades, their ‘share’ of the overall pool of academic literature has not increased in recent years. Mindfulness-related effort in the humanities, too, is at an all-time high, but not so from a ‘share’ perspective. Other disciplines are grabbing a larger slice of the pie. This bibliometric analysis aids the interdisciplinary field of mindfulness studies in exploring where they started, factors contributing to subsequent transformations, and how discrete contributing fields relate to one another in the context of the overall field of mindfulness studies.     

Italian American Ethnic Identity Persistence: A Qualitative Study

This study explores the persistence of ethnic identity among second- and fourth-generation Italian American emerging adults. In particular, the relational and college influences affecting its development were examined. The findings indicate that a distinct Italian American ethnic identity persists in this population, although it evolves with distance from the immigrant generation. We found that Italian American identity is relationally dynamic and shaped by many factors, most notably, family ethnic socialization, peer relationships, college experiences, ethnic pride, exposure to Italian culture, and life transitions. These findings extend our understanding of the cyclical nature of ethnic identity development within a specific ethnic group and the unique cultural forces shaping the identity of Italian Americans.     

Psychotherapy and counselling in Italy: A situation still in the phase of definition

This paper reflects on the state of psychotherapy and counselling in Italy, with specific attention to the situation within the public services. With regard to psychotherapy, several aspects of the current legislative status quo as well as the diffusion of this form of treatment are considered through two studies, one carried out in a region of the north of Italy and the other in a region of the south. After underlining the absence of precise epistemological, practical and legislative recognition of the activities that can be included under the heading of counselling, some of the principal practical areas where counselling is proving valuable in the Italian context are more closely examined.     

Psychodynamic counselling in a university setting: A space for thinking together over emotional problems

Abstract

The authors describe their experience as psychoanalytically oriented psychotherapists at the Counselling Service for University Students of the Office for Student Affairs, Naples. In this service they have provided, for the last fourteen years, to any student who applies to it, up to four individual sessions, with the possibility of follow-up sessions, should the client ask for them after a few months. Both the procedure and the aims of the interventions are similar to those described by psychotherapists working at the Tavistock Clinic (Copley 1976; Salzberger-Wittenberg 1977) and the Brent Consultation Centre (Hurry 1986; Novick 1987) of London. The technique is an adjustment of the psychoanalytic one and the therapist undertakes a careful listening to the student's verbal and non-verbal communications. The main objective of the intervention is to enter into an alliance with the adult parts of the client in order to examine together his/her personal difficulties. A case report is presented, in order to exemplify both an emotional conflict which can interfere with academic success and the technique of the intervention.
