  journal={Frontiers in Psychology},
This paper illustrates two psychometric methods, latent class analysis (LCA) and taxometric analysis (TA) using empirical data from research probing children's mental representation in science learning. LCA is used to obtain a typology based on observed variables and to further investigate how the encountered classes might be related to external variables, where the effectiveness of classification process and the unbiased estimations of parameters become the main concern. In the step-wise LCA… 

Dimensions over categories: a meta-analysis of taxometric research

The meta-analytic findings support the conclusion that the great majority of psychological differences between people are latently continuous, and that psychopathology is no exception.

Student ideas and misconceptions for the atom: A Latent Class Analysis with covariates

The current study investigates students’ fundamental ideas and misconceptions about ontological features of atoms identity and behaviour. These conceptions are being investigated across tasks with

Assessing Algorithmic Thinking Skills in Early Childhood Education

This chapter presents part of a wider project aimed at developing computational thinking assessment instruments for first and second grade primary school students. The applicability of the specific

Studying the coherence of studentsʼ portrayed representations of the atomic structure - Connections with conceptions and misconceptions

The present study investigated the association of students’ fundamental ideas and misconceptions about ontological features of atom identity and behavior with the formation of their portrayed

Attitudes towards the Use of Educational Robotics: Exploring Pre-Service and In-Service Early Childhood Teacher Profiles

The introduction of STEM education, and specifically the implementation of educational robotics (ER), has drawn researchers’ attention and has shown that teachers play a crucial role in leading this

An Analytic Cognitive Style Negatively Predicts a More Literal but Not a More Symbolic Religiosity Type

ABSTRACT The idea that a more analytic cognitive style is associated with lower religiosity is a theoretical prediction that has been challenged by some empirical findings. We conducted three studies

Latent Class Modeling of Children’s Preference Profiles on Tangible and Graphical Robot Programming

It is shown that children’s preference profiles in the domain of introductory programming are associated with gender and age for both interfaces.

Classification and evaluation of educational apps for early childhood: Security matters

This profile scheme is an indicative categorization summarizing the crucial features that popular apps possess and can help parents and/or educators’ decision-making on choosing the desirable application for their kids.

The Identification of Subphenotypes and Associations with Health Outcomes in Patients with Opioid-Related Emergency Department Encounters Using Latent Class Analysis

A latent class analysis was conducted using 14,057,302 opioid-related encounters from 2016 through 2017 using the National Emergency Department Sample (NEDS), the largest all-payer ED database in the United States, finding subphenotypes that provide a basis for examining patient-tailored approaches for this patient population.

Parents’ Perceptions of Educational Apps Use for Kindergarten Children: Development and Validation of a New Instrument (PEAU-p) and Exploration of Parents’ Profiles

A new instrument, named PEAU-p (Perceptions about Educational Apps Use–parents), was developed and validated in the present study designed to measure parents’ perception of educational apps for kindergarten pupils, investigating the influential role parents play in young children’s media selection and use.



Estimating the Association between Latent Class Membership and External Variables Using Bias-adjusted Three-step Approaches

Latent class analysis is a clustering method that is nowadays widely used in social science research. Researchers applying latent class analysis will typically not only construct a typology based on

Latent Class Modeling with Covariates: Two Improved Three-Step Approaches

The correction method of Bolck, Croon, and Hagenaars is extended by showing that it involves maximizing a weighted log-likelihood function for clustered data, which makes it possible to apply the method not only with categorical but also with continuous explanatory variables.

Differentiating Categories and Dimensions: Evaluating the Robustness of Taxometric Analyses

The impressive accuracy of the CCFI was consistent with prior findings and robust across novel manipulations of asymmetry, tail weight, and heterogeneous variances, as well as the practical implications for differentiating categories and dimensions.

Latent Class Analysis Results to Variables not Included in the Analysis

An important interest in mixture modeling is the investigation of what types of individuals belong to each latent class by relating classes to covariates, concurrent outcomes and distal outcomes,

Latent class and latent transition analysis

Often quantities of interest in psychology cannot be observed directly. These unobservable quantities are known as latent variables. By using multiple items as indicators of the latent variable, we

General Growth Mixture Analysis with Antecedents and Consequences of Change

Many studies of youth, adolescents, and adults related to delinquent, antisocial, and criminal offending, have utilized a language of trajectory typologies to describe individual differences in the

Using the Comparison Curve Fix Index (CCFI) in Taxometric Analyses: Averaging Curves, Standard Errors, and CCFI Profiles

A series of simulation studies examine the use of the CCFI to flesh out some empirically supported guidelines and find that constructing a CCFI profile can help to differentiate categorical and dimensional data and provide a less biased and more precise estimate of the taxon base rate than conventional methods.

The latent structure of life-course-persistent antisocial behavior: is Moffitt's developmental taxonomy a true taxonomy?

The results of this study suggest that LCP and AL antisocial behavior differ in degree rather than in kind (qualitative difference), which has potentially important implications for theory development as well as for clinical assessment, diagnosis, and intervention.

Does nature have joints worth carving? A discussion of taxometrics, model-based clustering and latent variable mixture modeling

This review shows why the results of a taxometric procedures, model-based clustering and latent variable mixture modeling investigation depend on the characteristics of the observed symptoms and the sample and argues that the choice of method should optimally match and make use of the existing knowledge about the data that are analyzed.
