Dynamics of the Stream of Thought: Insights from an Accumulation-to-Threshold Model
No full textThe dynamics of the stream of spontaneous thoughts has been the object of increasing research in recent years. Here, we study the timing of transitions from one coherent thought episode to the next as one aspect of such dynamics. Participants either vocalized spontaneously generated words or let their mind wander during 2 to 3-minute runs, and were instructed to report thought transitions with a key press. We first validate this subjective mental event segmentation, which enables us to measure the duration of coherent thought episodes. We then turn to model comparison to show that the timing of thought transitions is best explained by an accumulation-to-threshold mechanism. We further find that the threshold of this accumulation – but not the accumulation rate – negatively correlates with participants’ trait tendency for mind-wandering, highlighting the role of mental impulsivity in thought transitions
Study of the 'Same'-'Different' Task Using Abstract Stimuli
No full textThe "Same"-"Different" task evaluates the ability to detect differences between two stimuli. In this task, a pair of stimuli is presented successively, and the participant must decide whether the stimuli are identical or different. The dependent variables are response time and response accuracy. Since the 1960s, this task has mostly been conducted using verbalizable stimuli, which may introduce biases related to phonological representations. This study aims to isolate perceptual processes by using a set of abstract stimuli rigorously controlled for visual complexity. Two main hypotheses were tested: (1) in line with the "Fast-Same" effect, participants should respond more quickly to "Same" trials than to "Different" ones; (2) according to entropy theory, response times should increase proportionally with the degree of discordance between the stimuli. In a within-subjects experimental design, 24 participants completed 768 trials using these abstract stimuli. The trials varied according to the number of elements in the first stimulus (ranging from 1 to 4) and the number of discordant elements between the two stimuli (from 0 to total discordance). The results confirm that "Same" trials had shorter response times, supporting the first hypothesis. Moreover, response times increased linearly with the number of discordant elements, supporting the second hypothesis. This more refined analysis offers new insights into how visual complexity and discordance influence response speed and accuracy, with potential applications in domains requiring fast and precise visual recognition

Athlete Wellbeing in High-Performance Settings: A Scoping Review
No full textThis scoping review explores how high-performance sports organisations define athlete wellbeing. It identifies key wellbeing components and examines the contextual factors influencing the implementation of these frameworks within national and international sports settings
Establishing a Comprehensive Hierarchical construct of Eustress (CHE)
No full textThis repository contains data used to develop the Comprehensive Hierarchical construct of Eustress (CHE), a unified framework for understanding eustress. The dataset includes 80 articles that are organized by authors, publication year, research field, and type of research. For each article, we identified all features of eustress that were mentioned and organized them hierarchically into 3 high-level sources (goal-directed action, momentary experience, stable qualities) and 18 mid-level facets. The repository includes code to run descriptive and bibliometric analyses.

Reducing internalized HIV stigma with Intervention Mapping: The design, implementation, and evaluation of RESET (RESilience and Empowerment Training)
No full textHIV is a highly stigmatized condition, and negative beliefs about HIV and people with HIV are frequently internalized. This paper describes how we designed, implemented, and evaluated RESET, an intervention aiming to reduce internalized HIV stigma among people with HIV in the Netherlands. This face-to-face, three-session workshop series for people with HIV was designed, implemented, and evaluated with Intervention Mapping, a systematic approach to behavior change that uses theory and evidence, as well as participatory processes, in the planning of interventions. Intervention Mapping comprises six steps: 1) conducting a needs assessment and drafting a logic model of the problem; 2) specifying intervention outcomes and objectives, and drafting a logic model of change; 3) designing the intervention by selecting theory and evidence-based methods for behavior change and then developing their practical applications; 4) producing and pre-testing the intervention; 5) planning for implementation; and 6) planning process and effect evaluation. For each step, we describe the tasks involved and how we approached each task as we designed, implemented, and evaluated RESET. By transparently reporting how RESET was developed, we illuminate success and challenges in designing, implementing, and evaluating HIV stigma interventions. We also demonstrate how Intervention Mapping can be leveraged to develop effective interventions for reducing stigma, including internalized HIV stigma
