A neural network paradigm for modeling psychometric data and estimating IRT model parameters: Cross estimation network

Longfei Zhang & Ping Chen

This paper presents a novel approach known as the cross estimation network (CEN) for fitting the datasets obtained from psychological or educational tests and estimating the parameters of item response theory (IRT) models. The CEN is comprised of two subnetworks: the person network (PN) and the item network (IN). The PN processes the response pattern of individual respondent and generates an estimate of the underlying ability, while the IN takes in the response pattern of individual item and outputs the estimates of the item parameters. Four simulation studies and an empirical study were comprehensively and rigorously conducted to investigate the performance of CEN on parameter estimation of the two-parameter logistic model under various testing scenarios. Results showed that CEN effectively fit the training data and produced accurate estimates of both person and item parameters. The trained PN and IN adhered to AI principles and acted as intelligent agents, delivering commendable evaluations for even unseen patterns of new respondents and items.

Causal moderated mediation analysis: Methods and software

Xu Qin & Lijuan Wang

Research questions regarding how, for whom, and where a treatment achieves its effect on an outcome have become increasingly valued in substantive research. Such questions can be answered by causal moderated mediation analysis, which assesses the heterogeneity of the mediation mechanism underlying the treatment effect across individual and contextual characteristics. Various moderated mediation analysis methods have been developed under the traditional path analysis/structural equation modeling framework. One challenge is that the definitions of moderated mediation effects depend on statistical models of the mediator and the outcome, and no solutions have been provided when either the mediator or the outcome is binary, or when the mediator or outcome model is nonlinear. In addition, it remains unclear to empirical researchers how to make causal arguments of moderated mediation effects due to a lack of clarifications of the underlying assumptions and methods for assessing the sensitivity to violations of the assumptions. This article overcomes the limitations by developing general definition, identification, estimation, and sensitivity analysis for causal moderated mediation effects under the potential outcomes framework. We also developed a user-friendly R package moderate.mediation (https://cran.r-project.org/web/packages/moderate.mediation/index.html) that allows applied researchers to easily implement the proposed methods and visualize the initial analysis results and sensitivity analysis results. We illustrated the application of the proposed methods and the package implementation with a re-analysis of the National Evaluation of Welfare-to-Work Strategies (NEWWS) Riverside data.


Specificity ratings for Italian data

Marianna Marcella Bolognesi & Tommaso Caselli

Abstraction enables us to categorize experience, learn new information, and form judgments. Language arguably plays a crucial role in abstraction, providing us with words that vary in specificity (e.g., highly generic: tool vs. highly specific: muffler). Yet, human-generated ratings of word specificity are virtually absent. We hereby present a dataset of specificity ratings collected from Italian native speakers on a set of around 1K Italian words, using the Best-Worst Scaling method. Through a series of correlation studies, we show that human-generated specificity ratings have low correlation coefficients with specificity metrics extracted automatically from WordNet, suggesting that WordNet does not reflect the hierarchical relations of category inclusion present in the speakers’ minds. Moreover, our ratings show low correlations with concreteness ratings, suggesting that the variables Specificity and Concreteness capture two separate aspects involved in abstraction and that specificity may need to be controlled for when investigating conceptual concreteness. Finally, through a series of regression studies we show that specificity explains a unique amount of variance in decision latencies (lexical decision task), suggesting that this variable has theoretical value. The results are discussed in relation to the concept and investigation of abstraction.

Analysing data from the psycholinguistic visual-world paradigm: Comparison of different analysis methods

Aine Ito & Pia Knoeferle

In this paper, we discuss key characteristics and typical experiment designs of the visual-world paradigm and compare different methods of analysing eye-movement data. We discuss the nature of the eye-movement data visual-world studies and provide data analysis tutorials on ANOVA, t-tests, linear mixed-effects model, growth curve analysis, cluster-based permutation analysis, bootstrapped differences of time-series, generalised additive modelling, and divergence point analysis. The goal of the analysis comparison and tutorials is to enable psycholinguists to apply each analysis method to their own data. We discuss the advantages and disadvantages of each method and offer recommendations about how to select an appropriate method depending on the research question and the experiment design.


A modularity design approach to behavioral research with immersive virtual reality: A SkyrimVR-based behavioral experimental framework

Ze-Min Liu & Yu-Hsin Chen

Given the prevalence and increased interest to employ virtual reality technology in human behavioral research. An increase in the number of toolkits, toolbox, frameworks, and platforms to provide user’s a means to conduct human behavioral research in VR has been seen over the past decade. Despite this, numerous factors, such as limited fundings, personnel, time, and programming/art design proficiency continue to impede many users from efficiently carrying out behavioral experiments in VR. Hence, 5 years ago we began to conceptualize, create, and gradually develop and test a SkyrimVR-based behavioral experimental framework (SkyBXF) module that could fully utilize the rich resources provided by SkyrimVR and editable via Creation Kit. The goal was to provide researchers and students with minimal programming proficiency, 3D environment development expertise, time, and personnel; A ready-to-go behavioral experiment template to swiftly establish realistic virtual worlds that can be further customized for specific experimental needs. The initial thoughts for this project were something equivalent to Microsoft Powerpoint for creating slideshows, but for VR behavioral experiments. Where one could simply “install” SkyBXF and “load” a SkyBXF template and get right to conducting VR behavioral experiments! For more details on how to start a VR behavioral experiment using SkyBXF and the basic functions/options/controls of classic human behavior experiments, scan the QR code to visit our Github page.


OWLET: An automated, open-source method for infant gaze tracking using smartphone and webcam recordings

Denise M. Werchan, Moriah E. Thomason & Natalie H. Brito

Groundbreaking insights into the origins of the human mind have been garnered through the study of eye movements in preverbal subjects who are unable to explain their thought processes. Developmental research has largely relied on in-lab testing with trained experimenters. This constraint provides a narrow window into infant cognition and impedes large-scale data collection in families from diverse socioeconomic, geographic, and cultural backgrounds. Here we introduce a new open-source methodology for automatically analyzing infant eye-tracking data collected on personal devices in the home. Using algorithms from computer vision, machine learning, and ecological psychology, we develop an online webcam-linked eye tracker (OWLET) that provides robust estimation of infants’ point of gaze from smartphone and webcam recordings of infant assessments in the home. We validate OWLET in a large sample of 7-month-old infants (N = 127) tested remotely, using an established visual attention task. We show that this new method reliably estimates infants’ point-of-gaze across a variety of contexts, including testing on both computers and mobile devices, and exhibits excellent external validity with parental-report measures of attention. Our platform fills a significant gap in current tools available for rapid online data collection and large-scale assessments of cognitive processes in infants. Remote assessment addresses the need for greater diversity and accessibility in human studies and may support the ecological validity of behavioral experiments. This constitutes a critical and timely advance in a core domain of developmental research and in psychological science more broadly.


PLAViMoP database: A new continuously assessed and collaborative 3D point-light display dataset

Christel Bidet-Ildei, Victor Francisco, Arnaud Decatoire, Jean Pylouster & Yannick Blandin

It was more than 45 years ago that Gunnar Johansson invented the point-light display technique. This showed for the first time that
kinematics is crucial for action recognition, and that humans are very sensitive to their conspecifics’ movements. As a result, many of today’s researchers use point-light displays to better understand the mechanisms behind this recognition ability. In this paper, we propose PLAViMoP, a new database of 3D point-light displays representing everyday human actions (global and fine-motor control movements), sports movements, facial expressions, interactions, and robotic movements. Access to the database is free, at https://plavimop.prd.fr/en/motions. Moreover, it incorporates a search engine to facilitate action retrieval. In this paper, we describe the construction, functioning, and assessment of the PLAViMoP database. Each sequence was analyzed according to four parameters: type of movement, movement label, sex of the actor, and age of the actor. We provide both the mean scores for each assessment of each point-light display, and the comparisons between the different categories of sequences. Our results are discussed in the light of the literature and the suitability of our stimuli for research and applications.

 


Quantifying social semantics: An inclusive definition of socialness and ratings for 8388 English words


Veronica Diveica, Penny M. Pexman & Richard J. Binney

It has been proposed that social experience plays an important role in the grounding of concepts, and socialness has been proffered as a fundamental organisational principle underpinning semantic representation in the human brain. However, the empirical support for these hypotheses is limited by inconsistencies in the way socialness has been defined and measured. To further advance theory, the field must establish a clearer working definition, and research efforts could be facilitated by the availability of an extensive set of socialness ratings for individual concepts. Therefore, in the current work, we employed a novel and inclusive definition to test the extent to which socialness is reliably perceived as a broad construct, and we report socialness norms for over 8000 English words, including nouns, verbs, and adjectives. Our inclusive socialness measure shows good reliability and validity, and our analyses suggest that the socialness ratings capture aspects of word meaning which are distinct to those measured by other pertinent semantic constructs, including concreteness and emotional valence. Finally, in a series of regression analyses, we show for the first time that the socialness of a word’s meaning explains unique variance in participant performance on lexical tasks. Our dataset of socialness norms has considerable item overlap with those used in both other lexical/semantic norms and in available behavioural mega-studies. They can help target testable predictions about brain and behaviour derived from multiple representation theories and neurobiological accounts of social semantics.

Development of the Abbreviated Technology Anxiety Scale (ATAS)

ATAS wilson BRM 2022Matthew L. Wilson, Anne Corinne Huggins‐Manley, Albert D. Ritzhaupt, Krista Ruggles

The ubiquity of technology in contemporary society causes some to develop anxiety when forced to these tools, especially in academic contexts. To address this, we developed the Abbreviated Technology Anxiety Scale, or ATAS, a short, low-stakes 11-item scale for measuring technology anxiety. This article presents the scale and the multiphase process for its development through the gathering of validity evidence. ATAS scores were found to have an internally consistent structure, as well as correlate with other known measures of technology and anxiety.

Empirica: a virtual lab for high-throughput macro-level experiments

Abdullah Almaatouq, Joshua Becker, James P. Houghton, Nicolas Paton, Duncan J. Watts & Mark E. Whiting 

Virtual labs allow researchers to design high-throughput and macro-level experiments that are not feasible in traditional in-person physical lab settings. Despite the increasing popularity of online research, researchers still face many technical and logistical barriers when designing and deploying virtual lab experiments. While several platforms exist to facilitate the development of virtual lab experiments, they typically present researchers with a stark trade-off between usability and functionality. We introduce Empirica: a modular virtual lab that offers a solution to the usability-functionality trade-off by employing a “flexible defaults” design strategy. This strategy enables us to maintain complete “build anything” flexibility while offering a development platform that is accessible to novice programmers. Empirica’s architecture is designed to allow for parameterizable experimental designs, reusable protocols, and rapid development. These features will increase the accessibility of virtual lab experiments, remove barriers to innovation in experiment design, and enable rapid progress in the understanding of human behavior.

StimuliApp: Psychophysical tests on mobile devices

Rafael Marin-Campos, Josep Dalmau, Albert Compte, & Daniel Linares

Mobile handheld devices, such as smartphones or tablets, can now run psychophysical tests using StimuliApp. StimuliApp is an open-source application that includes many templates for stimuli creation (including gradients, gratings, random-dots, texts, and tones). The application also allows for the presentation of images, videos, and audio. And importantly, the timing is precise.


Quaddles: A multidimensional 3-D object set.

Marcus Watson, Benjamin Voloh, Milad Maghidazeh, & Thilo Womelsdorf

Studies of visual cognition often require novel 3D objects that can be defined in a parametric feature space. This article presents a new parametrically-defined multi-featured 3D object set, and provides a link to download the scripts and a detailed manual used to generate them, either as 3D .fbx files or as PNG files showing the objects from any desired angle (I have attached a few representative examples of the PNGs). At present the scripts allow the creation of over 250,000 objects that differ along several dimensions (e.g. colour, surface pattern, body shape, body texture, etc), and can easily be modified to include additional dimensions or new values along those dimensions.


Mental chronometry in the pocket? Timing accuracy of web applications on touchscreen and keyboard devices

Thomas Pronk, Reinout W. Wiers, Bert Molenkamp & Jaap Murre

Web applications can implement procedures for studying the speed of mental processes (mental chronometry) and can be administered via web browsers on most commodity desktops, laptops, smartphones, and tablets. The results of this research offer some guidelines as to what methods may be most accurate and what mental chronometry paradigms may suitably be administered via web applications. In controlled circumstances, as can be realized in a lab setting, very accurate stimulus timing and moderately accurate RT measurements could be achieved on both touchscreen and keyboard devices, though RTs were consistently overestimated. In uncontrolled circumstances, such as researchers may encounter online, stimulus presentation may be less accurate, especially when brief durations are requested (of up to 100 ms).


The “Small World of Words” English word association norms for over 12,000 cue words.

Simon De Deyne, Danielle Navarro, Amy Perfors, Marc Brysbaert, Gert Storms

Word associations have been used widely in psychology, but the validity of their application strongly depends on the number of cues included in the study and the extent to which they probe all associations known by an individual. In this work, we address both issues by introducing a new English word association dataset. We describe the collection of word associations for over 12,000 cue words, currently the largest such English-language resource in the world. Our procedure allowed subjects to provide multiple responses for each cue, which permits us to measure weak associations.


Validation of a matrix reasoning task for mobile devices

Anja Pahor, Trevor Stavropoulos, Susanne Jaeggi, and Aaron Seitz

Many cognitive tasks have been adapted for tablet-based testing, but tests to assess nonverbal reasoning ability, as measured by matrix-type problems that are suited to repeated testing, have yet to be adapted for and validated on mobile platforms. We developed the University of California Matrix Reasoning Task (UCMRT)—a short, user-friendly measure of abstract problem solving with three alternate forms that works on tablets and other mobile devices and that is targeted at a high-ability population frequently used in the literature (i.e., college students). UCMRT is reliable and has adequate convergent and external validity. UCMRT is self-administrable, freely available for researchers, facilitates repeated testing of fluid intelligence, and resolves numerous limitations of existing matrix tests.


Systematic mappings between semantic categories and types of iconic representations in the manual modality: A normed database of silent gesture

Gerardo Ortega & Aslı Özyürek

An unprecedented number of empirical studies have shown that iconic gestures—those that mimic the sensorimotor attributes of a referent—contribute significantly to language acquisition, perception, and processing. However, there has been a lack of normed studies describing generalizable principles in gesture production and in comprehension of the mappings of different types of iconic strategies. We report an empirically-validated database that includes a list of the most systematic silent gestures in the group of participants, a notation of the form of each gesture based on four features (hand configuration, orientation, placement, and movement), each gesture’s mode of representation, iconicity ratings, and professionally filmed videos that can be used for experimental and clinical endeavors.


SOLID-Similar object and lure image database

Darya Frank, Oliver Gray & Daniela Montaldi

Stimulus selection is a critical part of experimental designs in the cognitive sciences. Quantifying and controlling item similarity using a unified scale provides researchers with the tools to eliminate item-dependent effects and improve reproducibility. Here we present a novel Similar Object and Lure Image Database (SOLID) that includes 201 categories of grayscale objects, with approximately 17 exemplars per set. Unlike existing databases, SOLID offers both a large number of stimuli and a considerable range of similarity levels. Enabling this degree of control over similarity is critical for high-level studies of memory and cognition, and combining this strength with the option to use it across many trials will allow research questions to be addressed using neuroimaging techniques.


Motor content norms for 4,565 verbs in Spanish

Romina A. San Miguel Abella & María González-Nosti

Embodiment theory suggests that, during the processing of words related to movement, as in the case of action verbs, somatotopic activation is produced in the motor and premotor cortices. We developed a database of 4,565 verbs in Spanish through a survey filled out by 152 university students to provide a standardized data base concerning the motor content of Spanish verbs. The value for the motor content was obtained by calculating the average value from the answers of the participants. The database and the raw responses of the participants can be downloaded from this website: https://inco.grupos.uniovi.es/enlaces.


LADEC: The Large Database of English Compounds

Christina L. Gagné, Thomas L. Spalding, & Daniel Schmidtke

The Large Database of English Compounds (LADEC) consists of over 8,000 English words that can be parsed into two constituents that are free morphemes, making it the largest existing database specifically for use in research on compound words. Both monomorphemic (e.g., wheel) and multimorphemic (e.g., teacher) constituents were used. The items were selected from a range of sources, including CELEX, the English Lexicon Project, the British Lexicon Project, the British National Corpus, and Wordnet, and were hand-coded as compounds (e.g., snowball). Participants rated each compound in terms of how predictable its meaning is from its parts, as well as the extent to which each constituent retains its meaning in the compound. In addition, we obtained linguistic characteristics that might influence compound processing (e.g., frequency, family size, and bigram frequency). The database can be downloaded from https://era.library.ualberta.ca (search term: LADEC), formatted as text (.csv) or as a Stata datafile.
