After habituation, 30 English-speaking university students completed a four-phase protocol on two occasions separated by 1 week. HRV and pupillometry were continuously measured during the following phases: baseline, cognitive testing, guided breathing with nature immersion, and spontaneous breathing with nature immersion. Strong day-to-day relative reliability was confirmed for both HRV (pooled ICC: 0.75 to 0.83) and pupillometry (pooled ICC: 0.66 to 0.87). HRV metrics of sympathovagal balance in the time, frequency, and non-linear domains showed reactivity with significant differences between all phases. Pupillometry metrics increased progressively from cognitive testing to guided breathing nature immersion to nature immersion, suggesting psychological rather than respiratory influences. Relatively large minimal detectable change values were determined across HRV (22 to 54% deviation from baseline) and pupillometry (33 to 88% deviation from baseline) metrics. Although the relatively large ratio limits of agreement and minimal detectable change values suggest that detecting systematic changes in these metrics over time might be difficult at the individual level, strong relative reliability supports the use of HRV and pupillometry metrics to detect differences in sympathovagal balance between groups. Additionally, the responsiveness of these metrics demonstrates the efficacy of the proposed virtual reality protocol in inducing detectable physiological reactivity across HRV and pupillometry metrics.</p>","PeriodicalId":8717,"journal":{"name":"Behavior Research Methods","volume":"57 9","pages":"267"},"PeriodicalIF":3.9,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12364972/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144881969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a principal subfield, supervised ML has advanced mental health diagnostics and behavior prediction through classification and regression tasks. However, the complexity of ML methodologies and the absence of established norms and standardized pipelines often limit its adoption among psychologists. Furthermore, the black-box nature of advanced ML algorithms obscures how decisions are made, making it difficult to identify the most influential variables. Automated ML (AutoML) addresses these challenges by automating key steps such as model selection and hyperparameter optimization, while enhancing interpretability through explainable artificial intelligence (XAI). By streamlining workflows and improving efficiency, AutoML empowers users of all technical levels to implement advanced ML methods effectively. Despite its transformative potential, AutoML remains underutilized in psychological research, with no dedicated educational material available. This tutorial aims to bridge the gap by introducing AutoML to psychologists. We cover advanced AutoML methods, including combined algorithm selection and hyperparameter optimization (CASH), stacked ensemble generalization, and XAI. The utility of AutoML is demonstrated using the \"H2O AutoML\" R package with publicly available psychological datasets, performing regression on multi-individual cross-sectional data and classification on single-individual time-series data. We also provide practical workarounds for ML methods not currently supported in the package, so researchers can adopt alternative solutions when needed. These examples illustrate how AutoML democratizes ML, making it more accessible while providing advanced methodologies for psychological research.</p>","PeriodicalId":8717,"journal":{"name":"Behavior Research Methods","volume":"57 9","pages":"262"},"PeriodicalIF":3.9,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144871184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the existing literature, this experimental approach has been referred to as the compelled-response paradigm or the urgent paradigm. Replicating earlier findings by also applying the method to the flanker task of cognitive control, Lee et al. found that urgency opens up a time window in which stimulus-driven processing overtakes cognitively controlled processing and leads to actions against current intentions (as per task instructions). Taken together, this demonstrates how the method captures the temporal evolution of performance in high resolution, providing a window into the dynamics of cognitive processing in cognitive control tasks.

Specifically, this research has shown that the temporal binding window of audiovisual integration widens with advancing age, whereas individuals with various neurodevelopmental disorders exhibit distinctive profiles of multisensory processing when compared to their neurotypical counterparts. While this line of research has made significant inroads in emphasising the importance of multisensory processing in both typical and atypical cognition, the field would greatly benefit from the validation of web-based tools for assessing multisensory temporal processing, enabling larger sample sizes and the recruitment of typically hard-to-reach populations. Here, we assessed the reliability of a web-based version of the sound-induced flash illusion (SIFI) and examined the level of agreement between the measurements of the temporal binding window that it produces relative to those derived from the SIFI task performed under standard laboratory conditions. Our results demonstrate that both versions of the task elicit a robust SIFI effect and show a similar dependency on the stimulus onset asynchronies between the audiovisual stimuli. Furthermore, our analysis revealed strong correlations between the estimated measurements of both the width and peak amplitude of the temporal binding window derived from the online and lab-based task versions, confirming the suitability of the web-based task for assessing multisensory function. Future studies should extend the evaluation of this online implementation of the SIFI to clinical populations who exhibit impaired multisensory temporal processing, to assess its suitability for clinical research.</p>","PeriodicalId":8717,"journal":{"name":"Behavior Research Methods","volume":"57 9","pages":"261"},"PeriodicalIF":3.9,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12361292/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144871183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon encountering a word, readers experience a processing difficulty that is a linear function of that word's surprisal. Evidence for this effect has been established in the English language or using multilingual models to estimate surprisal across languages. At the same time, many language-specific models of unknown psychometric quality are made openly available. Here, we provide a systematic evaluation of the surprisal estimates of a collection of large language models, specifically designed for Dutch, examining how well they account for reading times in corpora of sentence, paragraph and book reading. We compare their performance to multilingual models and an N-gram model. While models' predictive power for reading times varied considerably across corpora, GPT-2-based models demonstrated superior overall performance. We show that Dutch large language models exhibit the same inverse scaling trend observed for English, with the surprisal estimates of smaller models showing a better fit to reading times than those of the largest models. We also replicate the linear effect of surprisal on reading times for Dutch. Both effects, however, depended on the corpus used for evaluation. Overall, these results offer a psychometric leaderboard of Dutch large language models and challenge the notion of a one-size-fits-all language model for psycholinguistic research. The surprisal estimates derived from all neural language models across the three corpora, along with the code to extract the surprisal, are made publicly available ( https://osf.io/wr4qf/ ).</p>","PeriodicalId":8717,"journal":{"name":"Behavior Research Methods","volume":"57 9","pages":"266"},"PeriodicalIF":3.9,"publicationDate":"2025-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12361287/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144871182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we first present a 'raincloud quartet' that underscores the added value of raincloud plots over the traditional presentation of means and confidence intervals. The added value of raincloud plots appears to be increasingly recognized: a focused literature review of plots in Psychonomic Bulletin & Review shows that 9% of plots in 2023 were raincloud plots. Another 29% of plots (vs. 2% in 2013) contained individual data points (i.e., raindrops), indicating a strong trend towards transparent and informative data visualization. To further encourage this trend and make raincloud plotting easy and practical for a broader group of researchers and students, we implemented a comprehensive suite of raincloud plots in JASP, an open-source statistics program with an intuitive graphical user interface.
