Although parenting styles constitute a well-known concept in research, two issues have largely been overlooked existing studies. In particular, the psychological control dimension has rarely explicitly modelled and there is limited insight into joint that simultaneously characterize maternal paternal practices their impact on child development. Using data from sample of 600 Flemish families raising an 8-to-10 year old child, we identified naturally occurring styles. A cluster analysis based...
Multivariate psychological processes have recently been studied, visualized, and analyzed as networks. In this network approach, constructs are represented complex systems of interacting components. addition to insightful visualization dynamics, a perspective leads new way thinking about the nature phenomena by offering tools for studying dynamical in psychology. article, we explain rationale associated methods visualization, illustrate it using an empirical example focusing on relation...
In recent years, network approaches to psychopathology have sparked much debate and had a significant impact on how mental disorders are perceived in the field of clinical psychology. However, there many important challenges moving from theory empirical research practice vice versa. Therefore, this article, we bring together different points view psychological networks by methodologists clinicians give critical overview these challenges, present an agenda for addressing challenges. contrast...
The current article aims to provide an up-to-date synopsis of available techniques study affect dynamics using intensive longitudinal data (ILD). We do so by introducing the following eight dichotomies that help elucidate what kind one has, process aspects are interest, and research questions being considered: (1) single- versus multiple-person data; (2) univariate multivariate models; (3) stationary nonstationary (4) linear nonlinear (5) discrete time continuous (6) variables; (7) frequency...
Emotion differentiation, which involves experiencing and labeling emotions in a granular way, has been linked with well-being. It theorized that differentiating between facilitates effective emotion regulation, but this link yet to be comprehensively tested. In two experience-sampling studies, we examined how negative differentiation was related (a) the selection of emotion-regulation strategies (b) effectiveness these downregulating ( Ns = 200 101 participants 34,660 6,282 measurements,...
In recent years, the popularity of procedures for collecting intensive longitudinal data, such as experience-sampling method, has increased greatly. The data collected using designs allow researchers to study dynamics psychological functioning and how these differ across individuals. To this end, are often modeled with multilevel regression models. An important question that arises when design studies is determine number participants needed test specific hypotheses regarding parameters...
Several three‐mode principal component models can be considered for the modelling of three‐way, data, including Candecomp/Parafac, Tucker3, Tucker2, and Tucker1 models. The following question then may raised: given a specific data set, which these should selected, at what complexity (i.e. with how many components)? We address this by proposing numerical model selection heuristic based on convex hull. Simulation results show that performs almost perfectly, except Tucker3 arrays least one...
The aim of the present study was to identify and account for individual differences in contextual experience anger its appraisals associations between both. Participants (N=832) engaged a directed imagery task descriptions unpleasant situations reported on their appraisal experience. Additionally, they filled out several dispositional questionnaires. results demonstrated that at basis lies an externally induced disadvantage, which many people elicits frustration. For some individuals, latter...
Previous research has shown that individual differences in negative emotion differentiation may play a prominent role well-being. Yet, many basic questions about remain unanswered, including how it relates and overlaps with related known dimensions of what its possible underlying processes are. To answer these questions, the current article we present three correlational studies chart nomological network terms personality, difficulties identifying describing feelings, several indicators...
One of the promises experience sampling methodology (ESM) is that a statistical analysis an individual's emotions, cognitions and behaviors in everyday-life could be used to identify relevant treatment targets. A requisite for clinical implementation outcomes such person-specific time-series analyses are not wholly contingent on researcher performing them. To evaluate this, we crowdsourced one individual patient's ESM data 12 prominent research teams, asking them what symptom(s) they would...
Emotion differentiation, the ability to make fine-grained distinctions between emotional states, has mainly been studied as a trait. In this research, we examine within-person fluctuations in emotion differentiation and hypothesize that stress is central factor predicting these fluctuations. We predict experiencing will result lower levels of differentiation. Using data from 3-wave longitudinal experience sampling study, examined level across days months tested if related changes levels. On...
Abstract Background Cueing can alleviate freezing of gait (FOG) in people with Parkinson's disease (PD), but using the same cues continuously daily life may compromise effectiveness. Therefore, we developed DeFOG‐system to deliver personalized auditory on detection a FOG episode. Objectives We aimed evaluate effects DeFOG during FOG‐provoking protocol: (1) after 4 weeks DeFOG‐use against an active control group; (2) immediate (within‐group) different medication states. Method In this...
This study examined the relative contribution and nature of dimensions underlying intracultural intercultural differences in recalled frequency emotional experience. From 48 nations, 9,300 participants provided self-reports experienced emotions several other variables relevant to The data were analyzed by means multilevel component analysis, which decomposes into components. results showed that positive affect negative emerged as universal differences, accounting for relatively largest part...
Many questions in the behavioral sciences focus on causal interplay of a number variables across time. To reveal dynamic relations between variables, their (auto- or cross-) regressive effects time may be inspected by fitting lag-one vector autoregressive, VAR(1), model and visualizing resulting regression coefficients as edges weighted directed network. Usually, raw VAR(1) are drawn, but we argue that this yield misleading network figures characteristics because two problems. First,...
The current research offers an alternative to essentialism for studying cultural variation in emotional experience. Rather than assuming that individuals always experience emotion the same way, our starting point was of like anger or shame may vary from one instance another. We expected find different and types, is, groups people who differ instances they proposed differences means distribution these types across contexts: There should be systematic are most common each culture. Students...
In psychology, modeling multivariate dynamical processes within a person is gaining ground.A popular model the lag-one vector autoregressive or VAR(1) and its variants, in which each variable regressed on all variables (including itself) at previous time point.Many parameters have to be estimated model, however.The question thus rises whether not too complex overfits data.If latter case, will properly predict new unseen data.As consequence, it cannot trusted that adequately characterize...
Affect is central to human functioning. Due its dynamic nature, it often studied with intensive longitudinal designs, yet the development and validation of measures for this purpose have received little systematic attention. In present study, we review theoretical methodological conceptualizations affect that are relevant repeated momentary positive negative measurement. We developed a questionnaire including six dimensional 22 discrete emotion items allowed us measure alternative constructs...
Detecting early signs of recurrence psychopathology is key for prevention and treatment. Personalized risk assessment especially relevant formerly depressed patients, whom common. We aimed to examine whether depression can be accurately foreseen by applying Exponentially Weighted Moving Average (EWMA) statistical process control charts Ecological Momentary Assessment (EMA) data. Participants were patients (n = 41) in remission who (gradually) discontinued antidepressants. completed five...
In this article, following an assumption that individualism and collectivism are separate factors, we have further established three central components of can be distinguished. the first part article examined whether proposed individualism—autonomy, mature self‐responsibility, uniqueness—can distinguished from each other in one cultural context, Estonia. A new scale was developed to measure aspects which demonstrated both reasonable internal‐consistency reliability as well convergent...
