Neurocognitive deficits in severe COVID-19 infection: Case series and proposed model.

Objective: To date, very few studies investigating neurocognitive deficits in COVID-19 have been published. This case series addresses cognition in post-COVID-19 patient by describing three patients in acute rehabilitation to inform a model of cognitive sequelae of COVID-19. Methods: Three English-speaking inpatients with severe symptoms and long-term intensive care unit (ICU) treatment are described. All patients had a premorbid history of hypertension and hyperlipidemia and experienced delirium and hypoxemia when hospitalized. Patient 1 is a 62-year-old male with 15 years of education with additional history of obstructive sleep apnea and type 2 diabetes. Patient 2 is a 73-year-old female with 12 years of education with a premorbid medical history of alcohol use disorder and Guillain-Barre syndrome. Patient 3 is a 75-year-old male with 14 years of education. No patients had premorbid psychiatric histories. Results: The three patients demonstrated deficits on formal neuropsychological testing, particularly with encoding and verbal fluency. Memory measures improved with a more structured story memory task compared to a less-structured verbal list-learning task, suggesting executive dysfunction impacted learning. None of the patients demonstrated rapid forgetting of information. Two patients endorsed new depressive and/or anxiety symptoms. Conclusions: The results suggest evidence for neurocognitive deficits after severe COVID-19 infection, particularly in encoding and verbal fluency. These results were interpreted with caution given the limited number of patients and the telephone-based battery. The specific mechanism that caused these cognitive deficits in these individuals remains unclear. A proposed three-stage model of cognitive dysfunction is described to help guide future research.

Maladaptive personality traits and romantic relationship satisfaction: A monozygotic co-twin control analysis.

The recent inclusion of an alternative model for personality disorders in the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition (DSM-5; American Psychiatric Association, 2013a) highlights the importance of extreme variants of personality for psychopathology. The maladaptive personality traits described in the alternative model comprise 5 higher-order domains and 25 lower-order facets that capture pathological levels of personality. The present report adds to a growing body of research on the implications of maladaptive personality traits for functioning by demonstrating significant associations between each of the higher-order domains (Negative Affect, Detachment, Antagonism, Disinhibition, and Psychoticism) and most of the lower-order facets and lower romantic relationship satisfaction in a population-based sample of 284 monozygotic (MZ) adult twins. We further capitalized upon co-twin differences in levels of personality pathology in a causally informative approach, the MZ co-twin control study design. Co-twin control analyses indicated that higher levels of Negative Affect, Detachment, Disinhibition, and Psychoticism, as well as several lower-order facets, were associated with lower romantic relationship satisfaction even after accounting for the genetic and environmental factors shared by twins that confer liability toward personality pathology and psychosocial dysfunction. The present results lend support to the potentially causal implications of personality pathology for interpersonal functioning, even in a community sample unlikely to be evidencing clinical levels of pathology, by suggesting that extreme variants of personality, manifested by comparably extreme deviations in thinking, feeling, behaving, and interacting with others, may lead to impaired functioning in important domains.

Writer-reader contagion of inspiration and related states: Conditional process analyses within a cross-classified writer × reader framework.

A longstanding tradition in the humanities holds that a writer's inspiration is infectious, but this thesis has not been tested. We hypothesized that (a) inspiration is infectious, such that inspired writers are more inspiring to the average reader; (b) contagion is mediated by the insightfulness of the text; and (c) contagion is moderated by readers' openness to experience, such that open readers are more prone to contagion. To test these hypotheses, a sample of 195 student writers, each of whom wrote 1 poem, was crossed with a sample of 220 student readers, who read all poems. Data were available for 36,020 cells of the resulting Writer × Reader matrix. Our analytic approach integrated cross-classified multilevel modeling with conditional process analysis. As hypothesized, writers who were more inspired elicited higher levels of inspiration in the average reader. Inspiration contagion was mediated by the insightfulness and pleasantness of the text and was partially suppressed by originality. Inspiration contagion was moderated by reader openness. Moderated mediation analyses indicated that open readers were prone to contagion because they were tolerant of the originality and sublimity of inspired writing. Additional analyses differentiated contagion of inspiration from contagion of its covariates (awe, positive affect), documented effects of writer inspiration on reader enthrallment (awe, chills), and showed that writer effort is a poor predictor of reader states. The infectiousness of inspiration-through poetry, if not also through scripture and academic writing-suggests that a given instance of inspiration may have far-reaching cultural implications, including dissemination of innovations and ideologies.

The scientific study of inspiration in the creative process: challenges and opportunities.

Inspiration is a motivational state that compels individuals to bring ideas into fruition. Creators have long argued that inspiration is important to the creative process, but until recently, scientists have not investigated this claim. In this article, we review challenges to the study of creative inspiration, as well as solutions to these challenges afforded by theoretical and empirical work on inspiration over the past decade. First, we discuss the problem of definitional ambiguity, which has been addressed through an integrative process of construct conceptualization. Second, we discuss the challenge of how to operationalize inspiration. This challenge has been overcome by the development and validation of the Inspiration Scale (IS), which may be used to assess trait or state inspiration. Third, we address ambiguity regarding how inspiration differs from related concepts (creativity, insight, positive affect) by discussing discriminant validity. Next, we discuss the preconception that inspiration is less important than "perspiration" (effort), and we review empirical evidence that inspiration and effort both play important-but different-roles in the creative process. Finally, with many challenges overcome, we argue that the foundation is now set for a new generation of research focused on neural underpinnings. We discuss potential challenges to and opportunities for the neuroscientific study of inspiration. A better understanding of the biological basis of inspiration will illuminate the process through which creative ideas "fire the soul," such that individuals are compelled to transform ideas into products and solutions that may benefit society.
