Psychosis,symbol, affectivity 2: another perspective on the treatment of psychotic disorder

This is the second of two papers concerning our study into an integrated approach to psychotic disorders conducted at the University Psychiatry Unit of Palermo’s Polyclinic over approximately 15 years; this paper concentrates on the clinical phenomena. The study aimed to find the best possible treatment and to improve the prognosis of this patient group. We have explored the efficacy of a range of psycho-therapeutic (cognitive-behavioural, systemic-relational, psychodynamic, group and others), psycho-pharmaceutical, psychiatric rehabilitative and psycho-educational treatments, with a hermeneutic approach instead of a systematic one. The study’s conclusions, described in the paper, are that all psychotic functions start with a nuclear psychic issue connected to emotional development. We describe how the most significant symptoms of acute psychotic manifestations (delusions and misperceptions) make use of an encrypted psychological meaning that can be decoded through the patient’s symbolic language. This language is a key element in diagnosis and in the choice of treatment. The paper describes how we revised our understanding of psychosis from being a brain disease to being a process aimed at the rearrangement of psychic functioning. Our significant results are described.     

Citations of Murray Sidman's work in JEAB: Evidence of a long and large contribution

We examined citations of Murray Sidman's publications in the Journal of the Experimental Analysis of Behavior from the journal's inception in 1958 through May 2020. On average, he was cited 35.6 times per year. The rate of citation did not change substantially across time and the cumulative citation count was 2,212. His 10 publications cited most often deal with behavior-analytic research methods, stimulus equivalence, and unsignaled free-operant (or Sidman) avoidance. Our data provide clear evidence of the breadth and depth of Sidman's influence on the experimental analysis of behavior across 7 decades. His contributions were both exceptional and praiseworthy and his legacy will long endure.     

Social cognition and social functioning in patients with amnestic mild cognitive impairment or Alzheimer’s dementia

The aim of the present study was to examine social cognition and social functioning in a group of amnestic mild cognitive impairment (aMCI) and Alzheimer’s dementia (AD) patients. Thirty one people with aMCI, 29 individuals with AD, and 45 healthy older adults participated in the study. Facial expressions of happiness, anger, fear, disgust, and surprise presented in different intensities had to be labelled. Mentalizing was assessed using first-order belief theory of mind (ToM) stories and everyday social functioning by the Inventory of Interpersonal Situations (IIS), completed by an informant. aMCI patients were impaired in recognizing the emotions anger, disgust, and fear, while AD patients were impaired in recognizing the emotions anger, disgust, and surprise. More importantly, no significant differences between aMCI and AD patients were found on overall emotion recognition. Both the aMCI and AD patients were impaired on the ToM task, but no differences between the aMCI and AD patients were found. On everyday social functioning, only the AD patients showed impairments. No associations between the IIS and ToM were found, but the IIS and emotion perception were significantly correlated. Regression analysis taking all potentially confounding variables into account showed that only mood, but not the social-cognitive task performance or any other cognitive variable, predicted social functioning. aMCI and AD patients demonstrated impairments in mentalizing and facial emotion perception, and showed decrements in everyday social functioning. Informing caregivers about these deficits may help them to understand deficits in social cognition that may be present already in the MCI stage of Alzheimer’s disease.     

Value-based choice: An integrative,neuroscience-informed model of health goals

Objective: Traditional models of health behaviour focus on the roles of cognitive, personality and social-cognitive constructs (e.g. executive function, grit, self-efficacy), and give less attention to the process by which these constructs interact in the moment that a health-relevant choice is made. Health psychology needs a process-focused account of how various factors are integrated to produce the decisions that determine health behaviour.

Design: I present an integrative value-based choice model of health behaviour, which characterises the mechanism by which a variety of factors come together to determine behaviour. This model imports knowledge from research on behavioural economics and neuroscience about how choices are made to the study of health behaviour, and uses that knowledge to generate novel predictions about how to change health behaviour. I describe anomalies in value-based choice that can be exploited for health promotion, and review neuroimaging evidence about the involvement of midline dopamine structures in tracking and integrating value-related information during choice. I highlight how this knowledge can bring insights to health psychology using illustrative case of healthy eating.

Conclusion: Value-based choice is a viable model for health behaviour and opens new avenues for mechanism-focused intervention.     

Marr,Mayr, and MR: What functionalism should now be about

In this review essay on The Multiple Realization Book by Polger and Shapiro, I consider the prospects for a biologically grounded notion of multiple realization (MR) which has been given too little consideration in the philosophy of mind and cognitive science. Thinking about MR in the context of biological notions of function and robustness leads to a rethink of what would count as a viable functionalist theory of mind. I also discuss points of tension between Polger and Shapiro’s definition of MR and current explanatory practice in neuroscience.     

Interpersonal perceptions of personality traits in elite coach-athlete dyads

IntroductionThe extent to which coaches and athletes can effectively work together is an essential consideration in the pursuit of athletic success. This is particularly important at the elite level due to the high pressures on tangible outcomes, such as reaching the podium of a major competition. This study sought to explore and explain how both coaches and athletes identify personality traits in themselves and their partners to manage and maintain a positive relationship.MethodsUsing a mixed methodological design underpinned by critical realism, four elite coach-athlete dyads (four male coaches, one male athlete, three female athletes) were purposefully recruited from a single sport. Each participant completed the 44-item Big Five Inventory (John & Srivastava, 1999) on their own and their partner’s perceived personality traits. The data generated were used to inform the discussions in follow-up, individual semi-structured interviews with all participants.ResultsThe interview data were analysed using thematic analysis, which generated three higher themes and seven lower order themes. The three higher order themes were perceived compatibility, relationship persona and collective personality.ConclusionThe present investigation has identified what coaches and athletes perceive to be the key personality characteristics to manage and maintain a successful working relationship.
