From Metaphor to Computation: Constructing the Potential Landscape for Multivariate Psychological Formal Models

Multivariate Behavioral Research, Год журнала: 2022, Номер 58(4), С. 743 - 761

For psychological formal models, the stability of different phases is an important property for understanding individual differences and change processes. Many researchers use landscapes as a metaphor to illustrate concept stability, but so far there no method quantify system’s phases. We here propose construct potential landscape multivariate models. This based on generalized function defined by Wang et al. (Citation2008) Monte Carlo simulation. Based we define three types phases: absolute relative geometric stability. The panic disorder model Robinaugh (Citation2019) used example, demonstrate how can be states phases, influence parameters, guide modifications. An R package, simlandr, was developed provide implementation method.

Multifractal Auditory Stimulation Promotes the Effect of Multifractal Torso Sway on Spatial Perception: Evidence from Distance Perception by Blindwalking

Ecological Psychology, Год журнала: 2023, Номер 35(4), С. 136 - 182

AbstractStimulation and movement interact non-linearly across multiple scales—a point empirically quantitatively available through multifractal structure. Multifractal movements might implicate stimulation. Previous correlational modeling of accelerometry-measured torso during blindwalking indicated that multifractality in predicts distance-perceptual judgments. We now experimentally tested whether stimulation interacted with to support distance perception. edited music-like sounds manipulate non-linearity auditory headphones participants perceiving by blindwalking—with eyes closed both Lap-1 instruction Lap-2 replication. Stimulation significantly predict distance-replication Low showed no effect. Medium produce over-/underestimation shorter/longer distances. Higher led replication enlisted longer time scales, drawing on prior non-linearity, i.e. from Lap 1, producing overestimation proportionally a greater standard deviation movements. Distance perception appears more accurate under medium rather than excessive resonating previous evidence walking engenders less other Movement-dependence is also unsurprising ecological-psychology wisdom. However, our knowledge, present results constitute an unprecedented step toward elaborating movement-dependence multifractal-geometrical approaches Disclosure statementNo potential conflict interest was reported the author(s).

Evaluating the impact of motivational interviewing on engagement and outcomes in a web-based self-help intervention for gambling disorder: A randomised controlled trial

Self-paced internet interventions for gambling problems offer cost-effective, accessible, and private alternatives to traditional psychotherapy a population that rarely seeks help. However, these have been relatively slow develop, evaluate, deploy at scale relative those other addictive behaviors. Moreover, user engagement remains low despite the high interest. Motivational interviews improved effectiveness bibliotherapy but not augmented with an analogous web-based self-guided program. This trial aimed replicate extend prior work by translating paperback workbook pairing it single motivational interview. It was hypothesized interview would enhance program outcomes. A two-arm randomised controlled conducted. Treatment-seeking Canadian adults recruited solely via social media received one year of access program, either alone (N = 158) or in combination virtual completed upon enrolment 155).

Specifying Transition Types and Scales of Interest in Understanding Clinical Change

Опубликована: Янв. 8, 2024

Sudden changes are often observed in clinical practice, yet a systematic framework to understand the underlying mechanisms is still lacking. In this article, we aim bridge gap by presenting for theoretical advancement and empirical investigation of sudden trajectories. We begin introducing features three distinct types transitions drawn from complex system research: bifurcation-induced tipping (B-tipping), noise-induced (N-tipping), rate-induced (R-tipping). Additionally, introduce distribution change (D-change), which does not experience single abrupt transition but its overall state distribution. use real-life examples illustrate how those can be connected phenomena. Finally, show why type may differ specific research questions, clearly defining interest required determining appropriate transition.

Transitions and resilience in ecological momentary assessment: A multiple single-case study

Journal for Person-Oriented Research, Год журнала: 2024, Номер 10(2), С. 89 - 99

Опубликована: Дек. 13, 2024

Ecological momentary assessment (EMA) of affect, cognition and behavior aims to provide a ‘window into person’s daily life’. But what should we look for through this window? In paper, compare statistical perspective, grounded in probability theory, with dynamic pattern complexity on two common phenomena EMA data: non-stationarity outlying values. From these are considered nuisances that be dealt with. contrast, may signal transitions from one another (e.g., transition neutral persistent sad mood), whereas values recovery perturbations stressful life events). We evaluated the view triangulation study multiple single cases took part Track your Mood study, where participants reported their emotions events 60 days. found was indeed related transition, were after perturbations. These findings show person-oriented research would benefit perspective can identify highly meaningful clinically relevant otherwise at risk being missed. Complementing time series contextual information qualitative data will essential genuinely understand phenomena.
