Motor Agency: A New and Highly Sensitive Measure to Reveal Agency Disturbances in Early Psychosis

Background: Early diagnosis of young adults at risk of schizophrenia is essential for preventive approaches of the illness. Nevertheless, classic screening instruments are difficult to use because of the non-specific nature of the signs at this preonset phase of illness. The objective of the present contribution was to propose an innovating test that can probe the more specific symptom of psychosis, i.e., the sense of agency, which is defined as being the immediate experience of oneself as the cause of an action. More specifically, we tested whether motor agency is abnormal in early psychosis. Methods: Thirty-two young symptomatic patients and their age-matched controls participated in the study. 15 of these patients were at ultra high-risk for developing psychosis (UHR), and 17 patients were suffering from first-episode psychosis (FEP). Patients ’ neurocognitive capacities were assessed through the use of seven neuropsychological tests. A motor agency task was also introduced to obtain an objective indicator of the degree of sense of agency, by contrasting force levels applied during other and self-produced collisions between a hand-held objet and a pendulum. Results: As reported in the literature for adult controls, healthy adolescents used more efficient force levels in self than in other-imposed collisions. For both UHR and FEP patients, abnormally high levels of grip force were used for self-produced collisions, leading to an absence of difference between self and other. The normalized results revealed that motor agency differentiated patients from controls with a higher level of sensitivity than the more classic neuropsychological test battery

First-Rank Symptoms in Schizophrenia: Reexamining Mechanisms of Self-recognition

Disturbances of self are a common feature of schizophrenic psychopathology, with patients reporting that their thoughts and actions are controlled by external forces, as shown in first-rank symptoms (FRS). One widely accepted explanatory model of FRS suggests a deficiency in the internal forward model system. Recent studies in the field of cognitive sciences, however, have generated new insights into how complex sensory and motor systems contribute to the sense of self-recognition, and it is becoming clear that the forward model conceptualization does not have unique access to representations about the self. We briefly evaluate the forward model explanation of FRS, reassess the distinction made between the sense of agency and body ownership, and outline recent developments in 4 domains of sensory-motor control that have supplemented our understanding of the processes underlying the sense of self-recognition. The application of these findings to FRS will open up new research directions into the processes underlying these symptoms

Exploring the indirect costs of a firm in business rescue

It may be argued that the indirect costs of financial distress are substantially higher than the direct costs. Consequently, indirect costs of participating in a formal turnaround may hinder the success of a reorganisation attempt. This study set out to explore the indirect costs financially distressed firms face as a consequence of participating in business rescue in South Africa. Due to the implicit nature of these costs, the focus was placed on investigating and identifying the sources of the indirect costs associated with business rescue. This study employed a qualitative research design, whereby semi-structured interviews were conducted with 13 business rescue practitioners. The study confirmed that firms may experience six difficulties during business rescue. However, there are several factors that influence the severity of these difficulties. Conversely, it appears that indirect costs may also offer firms several benefits. The results of the study may assist affected parties, as they offer some insight and clarity on the indirect costs of business rescue. Understanding indirect costs may assist stakeholders involved in the process to find strategies that will help to preserve the value of the firm and reduce the negative impact for all stakeholders involved.http://www.tandfonline.com/loi/rsar202020-12-17hj2020Business Managemen
