Introduction
I am interested in measuring latent traits such as personality, academic achievement, ability, etc. Therefore, I mainly engage myself in scale development and evaluation based on item response theory (IRT). I also engage myself in analysis of item response data. In addition, I also engage myself in researching solutions to various problems relating to scale development, evaluation, and analysis.

Due to the many advantages of online surveys, many researchers are taking advantage of this survey method. Although for many psychological instruments, previous studies have shown that online and paper-and-pencil administration formats have equivalent results, other studies have shown that some online surveys result in different score distributions...

Objectives Decreasing discrimination and stigma of dementia is an international issue. In 2004, the Japanese government changed the previous Japanese stigmatic term of dementia (“Chiho”) to the present one (“Ninchi‐sho”) a meaning near “neurocognitive disorder.” This study aimed to examine cross‐sectionally if the present term functioned well or no...

Background: A novel coronavirus, SARS-CoV-2, has spread widely throughout the world. To reduce the spread of infection, children are prevented from going to school and have fewer opportunities for in-person communication. Although the pandemic has affected the everyday lives of children, its impact on their development is unknown. This cross-sectio...

Longitudinal designs provide a strong inferential basis for uncovering reciprocal effects or causality between variables. For this analytic purpose, a cross-lagged panel model (CLPM) has been widely used in medical research, but the use of the CLPM has recently been criticized in methodological literature because parameter estimates in the CLPM con...
Article
Previous research has shown that executive function is correlated with prosocial behavior during early childhood. Whether early prosocial behaviors were associated with later executive function during preschool years or vice versa was thus examined in a longitudinal design. The prosocial behaviors and executive function of children (N = 64) aged 42...
Article
In this article, we first reviewed the research methods used in 29 articles published in The Japanese Journal of Educational Psychology during the past year and derived the typical case of research published in the journal. Based on this, we reviewed the measurements and evaluations carried out in these studies and discovered that recommendations m...
Article
The Basic Questionnaire on Behavior and Learning (BQBL) is a psychological scale constructed to measure several characteristics of developmental disorders, such as Autism Spectrum Disorder (ASD), Attention-Deficit/ Hyperactivity Disorder (ADHD), Learning Disorder (LD), and other developmental disorders, within schoolchildren. In this study, we cons...

Article
Identifying the cognitive capacities associated with the development of school readiness is indispensable to support children’s successful school transition. It has been shown that executive function (EF) in preschoolers is associated with both concurrent preacademic and subsequent academic skills. However, most research has controlled for the effe...

Having an imaginary companion (IC) is a fascinating example of children’s imaginative and pretend play. However, there are inconsistencies in the reported prevalence of children’s ICs. This study examined how culture may affect this prevalence. We conducted a meta-analysis to assess whether the culture as well as age, assessment method, sex, and bi...
Article
There is a theoretical debate regarding whether children represent God with reference to a human. Most previous studies have assessed this issue focusing on knowledge/omniscience in western children. This study used a theoretical framework characterising mental capacities in terms of motivational/emotional (experience) and cognitive (agency) mental...

Having an imaginary companion (IC) is an example of children's pretend play. However, most research regarding children's ICs is from Western cultures. In this study, the prevalence of ICs was assessed among Japanese children (2- to 9-year-old children, N = 800). The developmental (age), biological (sex), and environmental (birth order) effects on J...

In this paper, we introduced a method of causal inference for arbitrary treatment regimes. We first expounded the generalized propensity score (Imai & Van Dyk, 2004) that extended the propensity score for binary treatments, and then causal inference with this generalized propensity score. Furthermore, we reanalyzed the data of relations between mas...
Conference Paper
We are developing a Reading Skill Test (RST), which measures basic language skills relevant to reading (reading skills). In order to make the test maximally useful, we are developing it primarily as a tablet app. To examine the potential effects that tablet-based tests may have in comparison with paper-andpencil- based tests, we conducted an experi...
Article
In longitudinal design, investigating interindividual differences of intraindividual changes enables researchers to better understand the potential variety of development and growth. Although latent growth curve mixture models have been widely used, unstructured finite mixture models (uFMMs) are also useful as a preliminary tool and are expected to...
Article
Executive functions (EF) are an important predictor of later adaptive development. A number of environmental influences, such as parenting, have been suggested as important promoters of EF development. However, behavioural genetic research has demonstrated that many environmental influences could be affected by genetic influences. Therefore, it is...
Conference Paper
In this paper, in order to assess the effect of perceived autonomy on student engagement and academic performance in Japanese university students, we conducted two studies. In Study I, we created the Japanese student engagement scale. We then conducted surveys using this scale and, based on the resulting data, confirmed that the items in the scale...

It has been shown that there is a significant relationship between children's mentalizing skills and creation of an imaginary companion (IC). Theorists have proposed that interaction with an IC may improve mentalizing skills, but it is also possible that children's mentalizing skills affect their creation of an IC. In this longitudinal study, we ex...

In this study, we analyzed 79 Japanese schools of medicine to assess the effectiveness of learning environment and educational programs in universities. The results of a multiple logistic regression analysis showed that in medical education learning environment didn’t significantly affect educational outcome while educational programs did. The find...

A lightweight, human-in-the-loop evalua-tion scheme for machine translation (MT) systems is proposed. It extrinsically eval-uates MT systems using human subjects' scores on second language ability test problems that are machine-translated to the subjects' native language. A large-scale experiment involving 320 subjects revealed that the context-una...

In recent years, there have been important and immediate requirements to diagnose and improve the quality of higher education in Japan. In this paper, we applied principal component analysis to explore higher education indicators based on a published basic education database of Japanese national and public universities, including educational and re...
Article
In this study, we assessed the effect of local dependence on item parameter estimation based on comparable item parameters, using Markov Chain Monte Carlo method. The results showed that if we estimate item parameters ignoring local dependence, item parameter estimation will be more inaccurate than taking local dependence into account. Furthermore,...
Article
A set of items that have common stimulus is called testlet. Responses to the items in a testlet often violate the assumption of local independence. In this article, we compared three types of IRT models that take local dependence into account and standard IRT models in terms of accuracy of latent trait's estimation. Simulation results showed that t...
Article
In this study, using two models, Two-Parameter Logistic Interaction Model(2PLIM) and Two-Parameter Logistic Copula Model(2PLCM), which model local item dependence, simulations were conducted to investigate the effect on latent trait estimation in case of the assumption of local item independence violated. Through simulations, it was found that loca...
