Segmented Profile Analysis (SEPA) offers a unified, ipsatized singular-value decomposition (SVD) framework that decomposes individual profiles into orthogonal level (LE) and pattern (PE) effects and, crucially, introduces plane-wise segment profiles (summaries of each person's response pattern within each variable-contrast dimension) as primary person-oriented objects. Within each low-dimensional plane, SEPA defines a projected response pattern (segment profile), domain-person cosines that index variable-by-variable alignment, and plane-fit correlations that summarize how closely an individual's pattern follows the plane's domain structure. Across planes, SEPA aggregates information via singular-value weighting to yield an overall segment profile while preserving contrast-specific signal. A practical workflow combines ipsatized SVD, parallel analysis for PE dimensionality, marker-domain rules, bootstrap confidence intervals, and subspace-stability diagnostics. Using multivariate cognitive data from the Woodcock-Johnson IV, SEPA identifies interpretable marker domains, reveals distinct pattern facets across planes, and provides person-oriented indices that can be carried into standard regression models. Simulation studies examine the stability of segment profiles and cosines under varying sample sizes and variance structures. SEPA thus supplies a reproducible, geometry-based foundation for person-centered measurement that connects Q-type factor analysis, biplot methods, and contemporary within-person profiling in multidomain assessments.</p>","PeriodicalId":8717,"journal":{"name":"Behavior Research Methods","volume":"58 9","pages":""},"PeriodicalIF":5.0,"publicationDate":"2026-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13391806/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148560714","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}

To this end, we compared visual analogue scales (VAS) with different slider scales in an online study (N = 222) that built upon the original work by Reips and Funke (2008). In this study, participants were asked to estimate where a percentage value would lie on a line ranging from 0 to 100%. The slider scale conditions differed in the initialization of the slider thumb (left, middle, right), with an additional slider condition that employed the default HTML slider with a large thumb without any modifications. The findings of this study suggest that the measurement error in estimating the true value was lower in VAS than in slider scales. Additionally, our findings suggest that VAS lead to reduced variability in errors within and between individuals. Contrary to our initial hypothesis, we did not find a higher measurement error in the default slider than in the other slider conditions. The findings of this study suggest that VAS may offer a more precise means to the assessment of ratings.

We present a generalizable, user-friendly pipeline that enables synchronization of any two devices capturing the same physiological signals, without requiring coding expertise. The pipeline performs resampling, dynamic time warping alignment, amplitude correction via wavelet transforms, and signal standardization, followed by agreement analyses at both waveform and feature levels. To demonstrate its validity, we applied the pipeline to a case study comparing two research-grade devices, the Empatica E4 and the EmbracePlus, using up to 48 h of concurrent recordings from 31 participants. We compared signal-level agreement across waveform similarity, amplitude distribution, spectral content, and extracted features between the two research-grade devices to determine their interchangeability for longitudinal and multi-site studies. Specifically, we aimed to determine how well these devices agree at the signal level and to identify which physiological signals are most robust to device-specific variability. Four signals were examined (blood volume pulse, electrodermal activity, accelerometry, and temperature) using NeuroKit2 and FLIRT. We computed Pearson and concordance correlation coefficients, Bland-Altman bias and limits of agreement, root mean squared error (RMSE), KL divergence, spectral coherence, mutual information, and feature-level correlations using NeuroKit2 and FLIRT. Results showed near-perfect agreement for BVP (concordance correlation coefficient (CCC) ≈ 1.0; coherence ≤ 0.98) and phasic EDA features (CCC 0.85-0.99), whereas tonic EDA, temperature, and accelerometry exhibited systematic amplitude biases (EmbracePlus lower) and axis-dependent variability (Z-axis CCC = 0.85; Y-axis = 0.19).
