Psychometric and Validity Issues in Machine Learning Approaches to Personality Assessment: A Focus on Social Media Text Mining

In the age of big data, substantial research is now moving toward using digital footprints like social media text data to assess personality. Nevertheless, there are concerns and questions regarding the psychometric and validity evidence of such approaches. We seek to address this issue by focusing on social media text data and (i) conducting a review of psychometric validation efforts in social media text mining (SMTM) for personality assessment and discussing additional work that needs to be done; (ii) considering additional validity issues from the standpoint of reference (i.e. ‘ground truth’) and causality (i.e. how personality determines variations in scores derived from SMTM); and (iii) discussing the unique issues of generalizability when validating SMTM for personality assessment across different social media platforms and populations. In doing so, we explicate the key validity and validation issues that need to be considered as a field to advance SMTM for personality assessment, and, more generally, machine learning personality assessment methods. © 2020 European Association of Personality Psychology     

Development and validation of a measure of display rule knowledge: the display rule assessment inventory

As one component of emotion regulation, display rules, which reflect the regulation of expressive behavior, have been the topic of many studies. Despite their theoretical and empirical importance, however, to date there is no measure of display rules that assesses a full range of behavioral responses that are theoretically possible when emotion is elicited. This article reports the development of a new measure of display rules that surveys 5 expressive modes: expression, deamplification, amplification, qualification, and masking. Two studies provide evidence for its internal and temporal reliability and for its content, convergent, discriminant, external, and concurrent predictive validity. Additionally, Study 1, involving American, Russian, and Japanese participants, demonstrated predictable cultural differences on each of the expressive modes.     

On quasivarieties and varieties as categories

Finitary quasivarieties are characterized categorically by the existence of colimits and of an abstractly finite, regularly projective regular generator G. Analogously, infinitary quasivarieties are characterized: one drops the assumption that G be abstractly finite. For (finitary) varieties the characterization is similar: the regular generator is assumed to be exactly projective, i.e., hom(G, –) is an exact functor. These results sharpen the classical characterization theorems of Lawvere, Isbell and other authors.Supported by the Czech Grant Agency (Project 201/02/0148).Special issue of Studia Logica: Algebraic Theory of Quasivarieties Presented by M.

Modeling geometric–optical illusions: A variational approach

Visual distortions of perceived lengths, angles, or forms, are generally known as “geometric–optical illusions” (goi). In the present paper we focus on a class of gois where the distortion of a straight line segment (the “target” stimulus) is induced by an array of non-intersecting curvilinear elements (“context” stimulus). Assuming local target–context interactions in a vector field representation of the context, we propose to model the perceptual distortion of the target as the solution to a minimization problem in the calculus of variations. We discuss properties of the solutions and reproduction of the respective form of the perceptual distortion for several types of contexts. Moreover, we draw a connection between the interactionist model of gois and Riemannian geometry: the context stimulus is understood as perturbing the geometry of the visual field from which the illusory distortion naturally arises. The approach is illustrated by data from a psychophysical experiment with nine subjects and six different contexts.     

Intergenerational Coresidence and Life Satisfaction in Old Age: The Moderating Role of Homeownership

Household structure for older people’s subjective well-being is important to promote healthy ageing in the context of the rapid increase of the older population. Living with adult children is known to promote older people’s life satisfaction, a key indicator of subjective well-being, whereas others claim a negative impact of such intergenerational coresidence. This study aims to empirically test these theories (family support vs. family conflict), by examining the role of homeownership–another important factor contributing to subjective well-being–in this association between intergenerational coresidence and life satisfaction. Analysing the nationally representative data on the elderly population in South Korea, the findings showed that intergenerational coresidence decreases life satisfaction when the elderly achieve a certain level of housing security by living in owner-occupied housing. Living with adult children is negatively associated with life satisfaction particularly for older old homeowners compared to younger old owners. Our findings provide implications for public policies promoting intergenerational coresidence and asset-based welfare to enhance older people’s well-being in Korea and more broadly in East Asia.

     

Personality,Perceived Occupational Stressor,and Health-Related Quality of Life Among Chinese Judges

Personality is hypothesized to have direct and indirect effects on health-related quality of life (HRQoL) through the mediating role of perceived occupational stressors. This hypothesized model was tested with Chinese judges, individuals characterized by high occupational stress. In this cross-sectional study, 330 judges undergoing professional training at the Shandong Judge Training Institute completed questionnaires assessing their personality (Big Five Inventory, BFI), perceived occupational stressors (Occupational Role Questionnaire, ORQ), and HRQoL (Medical Outcomes Study Short-Form Health Survey, SF-36). The proposed model was tested using structural equation modelling (SEM) approaches. The SEM analysis showed a good fit of the data to the hypothesized model(x ²/df = 1.52, P?P?Neuroticism also had a negative indirect effect (?0.18, P?P?P?相似文献   

Auditory‐motor adaptation is reduced in adults who stutter but not in children who stutter

Previous studies have shown that adults who stutter produce smaller corrective motor responses to compensate for unexpected auditory perturbations in comparison to adults who do not stutter, suggesting that stuttering may be associated with deficits in integration of auditory feedback for online speech monitoring. In this study, we examined whether stuttering is also associated with deficiencies in integrating and using discrepancies between expected and received auditory feedback to adaptively update motor programs for accurate speech production. Using a sensorimotor adaptation paradigm, we measured adaptive speech responses to auditory formant frequency perturbations in adults and children who stutter and their matched nonstuttering controls. We found that the magnitude of the speech adaptive response for children who stutter did not differ from that of fluent children. However, the adaptation magnitude of adults who stutter in response to auditory perturbation was significantly smaller than the adaptation magnitude of adults who do not stutter. Together these results indicate that stuttering is associated with deficits in integrating discrepancies between predicted and received auditory feedback to calibrate the speech production system in adults but not children. This auditory‐motor integration deficit thus appears to be a compensatory effect that develops over years of stuttering.
