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.     

Egocentric metric representations in peripersonal space: A bridge between motor resources and spatial memory

Research on visuospatial memory has shown that egocentric (subject-to-object) and allocentric (object-to-object) reference frames are connected to categorical (non-metric) and coordinate (metric) spatial relations, and that motor resources are recruited especially when processing spatial information in peripersonal (within arm reaching) than extrapersonal (outside arm reaching) space. In order to perform our daily-life activities, these spatial components cooperate along a continuum from recognition-related (e.g., recognizing stimuli) to action-related (e.g., reaching stimuli) purposes. Therefore, it is possible that some types of spatial representations rely more on action/motor processes than others. Here, we explored the role of motor resources in the combinations of these visuospatial memory components. A motor interference paradigm was adopted in which participants had their arms bent behind their back or free during a spatial memory task. This task consisted in memorizing triads of objects and then verbally judging what was the object: (1) closest to/farthest from the participant (egocentric coordinate); (2) to the right/left of the participant (egocentric categorical); (3) closest to/farthest from a target object (allocentric coordinate); and (4) on the right/left of a target object (allocentric categorical). The triads appeared in participants' peripersonal (Experiment 1) or extrapersonal (Experiment 2) space. The results of Experiment 1 showed that motor interference selectively damaged egocentric-coordinate judgements but not the other spatial combinations. The results of Experiment 2 showed that the interference effect disappeared when the objects were in the extrapersonal space. A third follow-up study using a within-subject design confirmed the overall pattern of results. Our findings provide evidence that motor resources play an important role in the combination of coordinate spatial relations and egocentric representations in peripersonal space.     

Peer Influence: Mechanisms and Motivations

This research addresses a question that has not been previously – why do youths try to influence their friends’ behavior? Analysis of written accounts of peer influence toward both deviance and conformity reveals clear differences in motives for peer influence toward prosocial and deviant behavior. Influence toward deviant behavior is much more likely to be motivated by selfish concerns, and influence toward prosocial behavior is more likely to be motivated by altruistic concerns. These findings are consistent with the control theory view that crime and deviance is asocial behavior, and not the result of strong social ties to others.     

Damned if You Do,Damned if You Don’t: The Stigma of Weight Loss Surgery

Willpower, as demonstrated through diet and exercise, is constructed as the only acceptable strategy for losing weight. While weight loss surgery (WLS) is an option for morbidly obese individuals, like obesity itself, WLS carries stigma. Using a 40-item survey, we measured 101 participants’ experiences with WLS stigma. We examined whether WLS is stigmatizing, how that stigma is perceived by patients, and tendencies to hide their surgery status in order to manage stigma. Results indicated evidence of perceived stigma despite support from significant others as well as a tendency to hide surgery status from some people as a stigma management technique.     

Digging Deeper: Why Metaphysics is More Than a Toolbox

Steven French (J Gen Philos Sci,  https://doi.org/10.1007/s10838-018-9401-8, 2018) proposes a vindication of “scientifically disinterested” metaphysics that leaves little room to its original ambitions. He claims that (1) as a discipline that looks to find out truths about the world, it is untenable; and that (2) rather, its vindication lies in its use as a “toolbox” of concepts for a philosophical discipline that does have a claim at getting us closer to truth—the philosophy of science, and more specifically of physics. I respond to both his main claims. The first claim, I argue, neglects what I call (with Ralf Busse) “archaeological” metaphysics, which tries to impose some order on phenomena by “digging deeper” from the less to the more fundamental, or from the less to the more abstract questions. The second claim imposes a hierarchical relation between metaphysics and philosophy of science which should, I argue, be replaced with a more egalitarian picture of philosophy.     

Parents’ Judgments about the Desirability of Toys for Their Children: Associations with Gender Role Attitudes,Gender-typing of Toys,and Demographics

Parental toy selection and responses to toy play are important factors in children’s gender socialization. Reinforcing play with same-gender-typed toys guides children’s activities and limits their action repertoires in accordance with gender stereotypes. A survey of 324 Austrian parents of three- to six-year-old children was conducted to investigate parents’ judgments about the desirability of different types of toys for their children and how these judgements relate to parents’ gender-typing of toys, gender role attitudes, and demographics (age, education, gender). Results show that parents rated same-gender-typed and gender-neutral toys as more desirable for their children than cross-gender-typed toys. The traditionalism of parents’ gender role attitudes was not associated with their desirability judgments of same-gender-typed toys, but was negatively related to their desirability judgments of cross-gender-typed toys. This indicates that egalitarian parents permit a greater range of interests and behaviors in their children than traditional parents do. Younger parents, parents with lower educational levels, and fathers reported more traditional gender role attitudes than did older parents, parents with higher educational levels, and mothers. However, no differences based on age, educational level or gender were found in parents’ judgments of toy desirability. The present study demonstrates that parents’ judgments about the desirability of toys for their children do not accurately reflect their gender role attitudes. This finding highlights the importance of simultaneously investigating different aspects of parents’ gender-related attitudes in order to gain a better understanding of parental transmission of gender stereotypes.

Examining the neural antecedents of tics in Tourette syndrome using electroencephalography

Tourette syndrome (TS) is a neurodevelopmental disorder characterized by the occurrence of motor and vocal tics. TS is associated with cortical–striatal–thalamic–cortical circuit dysfunction and hyper-excitability of cortical limbic and motor regions that lead to the occurrence of tics. Importantly, individuals with TS often report that their tics are preceded by premonitory sensory/urge phenomena (PU) that are described as uncomfortable bodily sensations that precede the execution of a tic and are experienced as an urge for motor discharge. While tics are most often referred to as involuntary movements, it has been argued by some that tics should be viewed as voluntary movements that are executed in response to the presence of PU. To investigate this issue further, we conducted a study using electroencephalography (EEG). We recorded movement-related EEG (mu- and beta-band oscillations) during (1) the immediate period leading up to the execution of voluntary movements by a group of individuals with TS and a group of matched healthy control participants, and (2) the immediate period leading up to the execution of a tic in a group of individuals with TS. We demonstrate that movement-related mu and beta oscillations are not reliably observed prior to tics in individuals with TS. We interpret this effect as reflecting the greater involvement of a network of brain areas, including the insular and cingulate cortices, the basal ganglia and the cerebellum, in the generation of tics in TS. We also show that beta-band desynchronization does occur when individuals with TS initiate voluntary movements, but, in contrast to healthy controls, desynchronization of mu-band oscillations is not observed during the execution of voluntary movements for individuals with TS. We interpret this finding as reflecting a dysfunction of physiological inhibition in TS, thereby contributing to an impaired ability to suppress neuronal populations that may compete with movement preparation processes.
