Time series analysis psychology

Edward J Vinski
Although William James never again reprised his lectures on psychology for teachers at Harvard, he spent most of the 1890s presenting them throughout the country. For all his complaints about them, this was a fine source of income and he used the opportunity to revise and refine them over the rest of the decade. By the end of the 1890s, he was prepared to put the talks down in book form, and turned to his long-time publisher, Henry Holt. The two men first became acquainted with each other when James agreed to write a volume for Holt's American Science series...

RATIONALE: Supplemental oxygen is prescribed to patients with pulmonary fibrosis to normalize oxygen saturations, decrease symptoms and improve quality of life. Along with potential benefits, patients face challenges as they incorporate oxygen into their lives. OBJECTIVE: Our aim was to better understand the perceptions and experiences of patients with pulmonary fibrosis as they confronted the possibility and realities of using supplemental oxygen. METHODS: We performed a mixed-methods study in which we conducted a series of four structured telephone interviews with five patients with pulmonary fibrosis enrolled in a longitudinal observational study...

Preventative psychological interventions to aid women after traumatic childbirth are needed. This proof-of-principle randomized controlled study evaluated whether the number of intrusive traumatic memories mothers experience after emergency caesarean section (ECS) could be reduced by a brief cognitive intervention. 56 women after ECS were randomized to one of two parallel groups in a 1:1 ratio: intervention (usual care plus cognitive task procedure) or control (usual care). The intervention group engaged in a visuospatial task (computer-game 'Tetris' via a handheld gaming device) for 15 min within six hours following their ECS...

Heart rate (HR) and electrodermal activity (EDA) are often used as physiological measures of psychological arousal in various neuropsychology experiments. In this exploratory study, we analyze HR and EDA data collected from four participants, each with a history of suicidal tendencies, during a cognitive task known as the Paced Auditory Serial Addition Test (PASAT). A central aim of this investigation is to guide future research by assessing heterogeneity in the population of individuals with suicidal tendencies...

Psychophysiological interaction (PPI) is a widely used regression-based method to study connectivity changes in different experimental conditions. A PPI effect is generated by point-by-point multiplication of a psychological variable (experimental design) and a physiological variable (time series of a seed region). If the psychological variable is non-centered with a constant component, the constant component will add a physiological variable to the PPI term. The physiological component would in theory be accounted for by the physiological main effect in the model...

In the Kuwait context, from January 1991 to December 1991, there were a series of chemical and psychological Gulf War-era exposures that left persistent, long-term damage. Extreme stress from a critical event speeds up the usual disease latency period, and may be part of a synergistic effect that leads to higher disease rates over a shorter period of time. I am interested in the impact of armed conflict on health outcomes over the life course in Kuwait, and particularly the pathways through which armed conflict causes changes in health on a population level...

Background: The consumption of certain drugs can cause urinary incontinence. The aim of this study is to determine the frequency of consumption of drugs that can favour incontinence, the incidence of polypharmacy and the incidence of potentially dangerous drug-drug interactions in female patients suffering from overactive bladder (OAB) who presented to a urogynaecological outpatient department. Methods: We undertook a retrospective case series study. The data from 100 female patients who attended the urogynaecological outpatient department of the Vienna General Hospital [VGH; Allgemeinen Krankenhauses Wien (AKH)] in the period from 20...

Recent work has highlighted that process-outcome relationships are likely to vary depending on the client, yet there is little direct evidence regarding specific intervention effects in individual clients. This study attempted to address the hypothesis that some clients reveal more than others regarding the impact of specific interventions. Intensive case study analyses were applied to 2 clients with principal major depressive disorder and comorbid anxiety disorders receiving transdiagnostic psychotherapy. Clients completed a battery of symptom and psychological assessments of mindfulness, cognitive reappraisal use, and emotion avoidance on many occasions throughout treatment...

BACKGROUND: Maltreatment of older people (elder abuse) includes psychological, physical, sexual abuse, neglect and financial exploitation. Evidence suggests that 10% of older adults experience some form of abuse, and only a fraction of cases are actually reported or referred to social services agencies. Elder abuse is associated with significant morbidity and premature mortality. Numerous interventions have been implemented to address the issue of elder maltreatment. It is, however, unclear which interventions best serve to prevent or reduce elder abuse...

We introduce a novel method for delineating context-dependent functional brain networks whose connectivity dynamics are synchronized with the occurrence of a specific psychophysiological process of interest. In this method of context-related network dynamics analysis (CRNDA), a continuous psychophysiological index serves as a reference for clustering the whole-brain into functional networks. We applied CRNDA to fMRI data recorded during the viewing of a sadness-inducing film clip. The method reliably demarcated networks in which temporal patterns of connectivity related to the time series of reported emotional intensity...

BACKGROUND: The importance of supportive social relationships for psychological well-being has been previously recognized, but the direction of associations between both dimensions and how they evolve when adolescents enter adulthood have scarcely been addressed. The present study aims to examine the gender-specific associations between self-reported friendship network quality and psychological well-being of young people during the transition from late adolescence to young adulthood by taking into account the direction of association...

BACKGROUND: There is growing research and policy interest in the potential for using the natural environment to enhance human health and well-being. This resource may be underused as a health promotion tool to address the increasing burden of common health problems such as increased chronic diseases and mental health concerns. Outdoor environmental enhancement and conservation activities (EECA) (for instance unpaid litter picking, tree planting or path maintenance) offer opportunities for physical activity alongside greater connectedness with local environments, enhanced social connections within communities and improved self-esteem through activities that improve the locality which may, in turn, further improve well-being...

Structural vector autoregressive models (VARs) hold great potential for psychological science, particularly for time series data analysis. They capture the magnitude, direction of influence, and temporal (lagged and contemporaneous) nature of relations among variables. Unified structural equation modeling (uSEM) is an optimal structural VAR instantiation, according to large-scale simulation studies, and it is implemented within an SEM framework. However, little is known about the uniqueness of uSEM results...

In this article, I argue for the need of more use of exploratory techniques to identify dynamics in social interactions. I describe several approaches as they are applied to multivariate time series data. The first approach is an algorithm that searches for periods of variability and stability at the individual level as well as for patterns of overlap in such periods between the two individuals in a couple. These patterns describe the daily ups and downs in the couples' affect and are predictive of the state of the couples 1 to 2 years later...
