Inferential models in psychophysics are essential for quantifying the relation between physical properties of the stimulus and their perceptual representations. The psychometric function is typically used to model the responses of individual participants in forced-choice experiments. The accuracy and the noise of the…

Duration discrimination data collected with single-presentation tasks (e.g., bisection or temporal generalization tasks) or dual-presentation tasks (e.g., greater-less or same-different tasks) are usually analyzed by fitting psychometric functions. The independent variable in these functions is test duration measured…

We study a binary choice problem in which an agent chooses between two actions whose payoff depends on a continuous state. The agent chooses how much effort to invest in learning about the state. Equivalently, we can think of the state as the strength of a stimulus, with the agent exerting costly effort to be more…

Behavioral experiments are often infeasible when stimulus spaces have many dimensions or when testing time is limited. One way to address this challenge is adaptive stimulus selection, where informative stimuli are chosen dynamically based on participants’ responses. However, in high-dimensional spaces, identifying…

Objective: To evaluate the psychometric properties of the short version of the Token Test (SVTT) and the Rey-Osterrieth Complex Figure (ROCF) using an item response theory (IRT) framework and to establish normative data for Colombian children and adolescents based on ability scores. Methods: A total of 668 healthy…

Perceptual experience is influenced by alpha-band oscillations (8–14 Hz) that dominate parietal and sensory cortices. However, there is uncertainty around the perceptual mechanisms that are affected by oscillatory power and phase. Previous work has linked power and phase to behaviour separately despite their theorised…

1## Introduction Executive function refers to a complex set of higher order cognitive operations that includes working memory, inhibitory control, cognitive flexibility, planning, reasoning, and problem solving (Cristofori et al. ; Lezak et al. ; Welsh and Pennington ). Executive function controls and regulates a…

Large language models (LLMs) hold the potential to absorb and reflect personality traits and attitudes specified by users. In our study, we investigated this potential using robust psychometric measures. We adapted the most studied test in psychological literature, namely Minnesota Multiphasic Personality Inventory…

The same validation procedure as described in the original FUNMOVES study was followed, including Rasch analysis and concurrent and predictive validity analysis . The Rasch model, a probabilistic method from Item Response Theory, was used to assess the tool’s psychometric properties. It evaluates whether a total score…

psychophysiological modalities Authors: Harold A. Rocha, Amanda Holbrook, Greg Hajcak, Andreas Keil, Philippe Rast, Julian F. Thayer, Edelyn Verona, Walter P. Vispoel, Peter E. Clayson Psychophysiological research relies on biological measures to understand cognitive, affective, and behavioral processes, but the…

Imagining actions is a covert and multidimensional skill difficult to quantify. Comprehensive assessments rarely combine measures of imagery generation, maintenance, and manipulation. We developed and validated a combination of tests to assess these processes of movement imagery, online. 180 healthy individuals…

Background/Objectives: Haemophilia-related bleedings primarily affect the musculoskeletal system, and functional tests are used in clinical management. Yet, fine motor skills of the upper extremities have not been evaluated in adult persons with haemophilia (PwH). The Moberg Pick-Up Test (MPUT) assesses fine motor…

The use of continuous rating scales such as the visual analogue scale (VAS) in research has increased, yet they are less popular than discrete scales like the Likert scale. The non-popularity of continuous scales is primarily due to the lack of validated analytical tools and user-friendly interfaces, which have also…

We administer 45 validated psychometric questionnaires to 50 large language models (LLMs) to identify the dimensions along which LLMs differ psychometrically. Using Supervised Semantic Differential (SSD), we find that the primary axis of between-model variance separates items describing phenomenally rich experience…

Network psychometrics conceptualises psychological constructs as emergent properties of systems of interacting variables. Energy-based probabilistic models have gained popularity as models of these interactions, but their psychometric application has so far been limited, since most implementations assume binary or…

Artificial intelligence systems that model and support human cognition require reliable measures of cognitive state. We present the Focus Performance Score (FPS) from the Pulse Focus mobile Stroop application and evaluate whether it measures attentional control during color-word conflict resolution. We conduct…
Deng, Xueqing
In real life, psychological and physiological states rarely change along a single dimension. Through self-tracking and discussions with clinicians, I have come to recognise with increasing clarity that sleep patterns, autonomic arousal, bodily sensations, and cognitive load are in constant interaction. Existing models…

Identifying robust brain-psychopathology associations with neuroimaging remains difficult, in part due to substantial heterogeneity within and comorbidity between diagnostic categories. Transdiagnostic latent factor models aim to address this structure by separating shared and unique symptom variance. However, it…

Executive functions (EF) are higher-order cognitive processes essential for academic performance in university settings. Although there is extensive research on EF training in children, studies in young adults are scarce, particularly those involving interventions tailored to specific needs. To evaluate the effect of…
