Metacognitive function and fragmentation in schizophrenia: Relationship to cognition, self-experience and developing treatments

Bleuler suggested that fragmentation of thought, emotion and volition were the unifying feature of the disorders he termed schizophrenia. In this paper we review research seeking to measure some of the aspects of fragmentation related to the experience of the self and others described by Bleuler. We focus on work which uses the concept of metacognition to characterize and quantify alterations or decrements in the processes by which fragments or pieces of information are integrated into a coherent sense of self and others. We describe the rationale and support for one method for quantifying metacognition and its potential to study the fragmentation of a person\u27s sense of themselves, others and the relative place of themselves and others in the larger human community. We summarize research using that method which suggests that deficits in metacognition commonly occur in schizophrenia and are related to basic neurobiological indices of brain functioning. We also present findings indicating that the capacity for metacognition in schizophrenia is positively related to a broad range of aspects of psychological and social functioning when measured concurrently and prospectively. Finally, we discuss the evolution and study of one therapy that targets metacognitive capacity, Metacognitive Reflection and Insight Therapy (MERIT) and its potential to treat fragmentation and promote recovery

Oceanic cosmopolitanism: the complexity of waiting for future climate refugees

Waiting may feel like wasted time for people inhabiting small, low-lying, and extremely vulnerable island states as they await rising sea levels. Their homes may soon become uninhabitable due to climate change. The interplay between accelerating natural hazards, an increasing number of climate refugees, and the lack of adequate international refugee protection can prolong their waiting time. Therefore, I examine this experience within the complexity of the waiting framework consisting of existential, legal, and natural waiting. I explore the negative implications of climate refugees’ waiting and how such waiting may be prevented.publishedVersio

Being True, Sounding False

The essay explores multiple senses of “true,” arguing that truth not only has a performative sense, but that certain performances can themselves be true as when a friend is a true friend. Taking that thought in a metaphilosophical direction, the essay also argues that writing can be true to philosophy or sound false on those terms

Empirical Relationship between Nightside Reconnection Rate and Solar Wind / Geomagnetic Measurements

According to the expanding-contracting polar cap paradigm (ECPC), dayside and nightside reconnection control magnetosphere-ionosphere dynamics at high latitudes by increasing and decreasing the open magnetic flux content, respectively. The dayside reconnection rate can be estimated using parameters measured in the solar wind, but there is no reliable and available proxy for the nightside reconnection rate. We aim to remedy this by using AMPERE to estimate a time series of open flux content. The AMPERE data set originates from the global Iridium satellite system, enabling continuous measurements of the field-aligned Birkeland currents, from which the open magnetic flux of the polar caps is derived. This method provides seven years of open flux change estimates. A series of nightside reconnection rates are then derived by directly relating the dayside reconnection rate to the estimated open flux change. Various proxies for the nightside reconnection rate are estimated by relating several geomagnetic indices with our estimated nightside reconnection rate through multivariate regression analysis. By comparing the estimated open flux change with solar wind conditions and geomagnetic indices, we find our open flux estimates are highly dependent on the magnitude of the Birkeland currents. During low activity periods, the estimated open flux proves to be highly inaccurate with improving accuracy for higher activity periods. We also find that the nightside reconnection rate proxies fail to explain the majority of the variation in our estimated nightside reconnection rate series and propose that this is mainly due to the inaccuracy of our open flux estimates.Masteroppgave i fysikkPHYS399MAMN-PHY

Metacognitive self-reflectivity moderates the relationship between distress tolerance and empathy in schizophrenia

Deficits in empathy seen in schizophrenia are thought to play a major role in the social dysfunction seen in the disorder. However, little work has investigated potential determinants of empathic deficits. This study aimed to fill that gap by examining the effects of two variables on empathy – distress tolerance and metacognitive self-reflectivity. Fifty-four people with schizophrenia-spectrum disorders receiving services at an urban VA or community mental health center were assessed for empathy, metacognition, and distress tolerance. Bivariate correlations and moderation methods were used to ascertain associations amongst these variables and examine interactions. Results revealed that, against hypotheses, empathy was not related at the bivariate level to either distress tolerance or metacognitive self-reflectivity. However, consistent with hypotheses, moderation analyses revealed that participants with higher self-reflectivity showed no relationship between distress tolerance and empathy, while those with lower self-reflectivity showed a relationship such that reduced ability to tolerate distress predicted reduced empathy. Taken together, results of this study suggest that lack of distress tolerance can negatively affect empathy in people with schizophrenia with lesser capacity for metacognitive self-reflection; thus, fostering self-reflectivity may help overcome that negative impact. Future work is needed investigating the impact of metacognitively-tailored interventions on empathy in this population

Metacognition over time is related to neurocognition, social cognition, and intrapsychic foundations in psychosis

Core impairments underlying schizophrenia encompass several domains, including disruptions in metacognition, neurocognition, social cognition, and intrapsychic foundations. Little is known about how these phenomena change over time and whether changes co-occur. The current study sought to address these gaps and examine the relationships between these cognitive domains across a 12 month period in adults with schizophrenia. Seventy-five adult outpatients with schizophrenia spectrum disorders were enrolled in a randomized trial comparing two cognitive interventions designed to improve work performance. Cognitive outcomes were measured at baseline, a 6-month follow-up and a 12-month follow-up. Multilevel linear modeling was used to understand the longitudinal relationships between metacognition and social cognition, neurocognition, and intrapsychic foundations across the 12-month follow-up. Metacognition significantly improved across 12 months. Improvements in overall neurocognition were significantly associated with increases in the metacognition domains of self-reflectivity and mastery across time. Improvements in social cognition over time were associated with improvements in total metacognition and the metacognitive domain of mastery. Improvements in intrapsychic foundations scores over 12 months were significantly associated with improvements in overall metacognition, self-reflectivity, and mastery. In conclusion, over time, improvements in metacognition across domains co-occur with other core cognitive and social capacities in persons with schizophrenia. As persons became better able to form integrated senses of themselves and adaptively use this knowledge, improvements in neurocognition, social cognition, and intrapsychic foundations were also present

Metacognition in schizophrenia disorders: Comparisons with community controls and bipolar disorder: Replication with a Spanish language Chilean sample

Metacognition refers to the activities which allow for the availability of a sense of oneself and others in the moment. Research mostly in North America with English-speaking samples has suggested that metacognitive deficits are present in schizophrenia and are closely tied to negative symptoms. Thus, replication is needed in other cultures and groups. The present study accordingly sought to replicate these findings in a Spanish speaking sample from Chile. Metacognition and symptoms were assessed among 26 patients with schizophrenia, 26 with bipolar disorder and 36 community members without serious mental illness. ANCOVA controlling for age and education revealed that the schizophrenia group had greater levels of metacognitive deficits than the bipolar disorder and community control groups. Differences in metacognition between the clinical groups persisted after controlling for symptom levels. Spearman correlations revealed a unique pattern of associations of metacognition with negative and cognitive symptoms. Results largely support previous findings and provide added evidence of the metacognitive deficits present in schizophrenia and the link to outcome cross culturally. Implications for developing metacognitively oriented interventions are discussed
