There is contradictory evidence regarding whether the impairments of recognition emotional facial expressions in Parkinson's disease are specific to certain emotions such as disgust and fear. Generally, neurological case reports on emotion-specific have been suspected being confounded with factor task difficulty. Using a refined assessment method which difficulty factors were controlled by means mixed item response theory, we attempted clarify disproportionately impaired emotions. We studied...

本研究は,Grayの強化感受性理論 (Reinforcement Sensitivity Theory) に基づいた2つの気質次元,行動抑制系 (Behavioral Inhibition System) と行動賦活系 Activation について,日本語版尺度の信頼性・妥当性の検討(研究1),生物学的基盤との対応関係の検討(研究2)を行った。研究1では,大学生446名を対象に質問紙調査を行い,Carver & White (1994) が作成した尺度の日本語版の信頼性を確認した。また,因子的妥当性,構成概念妥当性の検討を行い,十分な結果を得た。研究2では,慶應義塾双生児プロジェクトによって集められた双生児を対象に質問紙調査を実施し,293組から有効な回答を得た。行動遺伝学的解析の結果,BISとBASは遺伝要因によって部分的に説明され,お互いに独立な遺伝因子から寄与を受けていることが分かった。

This study investigated the relationship between Revised Competitive State Anxiety Inventory-2 (CSAI-2R, Cox, Martens, & Russell, 2003; Jones Swain, 1992; Vealey, Burton, 1990) subscales and quality of music performance to compare anxiety-performance in pianists with that athletes gain insights into effective coping strategies for anxiety (MPA). Fifty one students (15 women 36 men) aged 18–26 years ( M = 20.6, SD 2.3) completed CSAI-2R just prior their individual piano performances a...

本研究は,成人用エフォートフル・コントロール(EC)尺度日本語版を作成し,その信頼性・妥当性の検討を行った.研究1では,大学生,専門学校生209名を対象に質問紙調査を行い,日本語版EC尺度とその下位尺度が必要な内的一貫性,再検査信頼性を持つことを確認した.また,新奇性追求,損害回避,ビッグ・ファイブのパーソナリティ次元,および抑うつ・不安との関連性から,尺度の構成概念妥当性が支持された.研究2では,日本語版EC尺度が単なる自己認知のみでなく実際の実行注意を測定しているか否かを検討するため,研究1の参加者のうち大学生47名を対象にストループ課題を行い,干渉効果の程度と日本語版EC尺度との関連を検討した.日本語版EC尺度合計および「行動抑制の制御」下位尺度は一致試行における誤反応率と負の相関を示し,また尺度合計および「行動抑制の制御」,「注意の制御」下位尺度は干渉効果の大きさと負に相関した.この結果から,尺度の基準関連妥当性が確認された.

Abstract This study examined the relationship between early parental treatment, specifically reading to young children and later cognitive development with a Bayesian perspective. Previous research established positive link infants their development, such as receptive vocabulary, comprehension motivation read. Using data from Millennium Cohort Study, this analysed individuals aged 9 months 14 years investigate effects of on nine variables. statistical analysis controlled for pre‐existing...

Whether an examinee has information about a crime is determined by the Concealed Information Test based on autonomic differences between crime-related item and other control items. Multivariate quantitative statistical methods have been proposed for this determination. However, these require specific databases of responses, which are problematic field application. Alternative methods, using only individual's data, preferable, but traditionally such within-individual approaches limitations...

The authors propose a concise formula to evaluate the standard error of estimated latent variable score when true values structural parameters are not known and must be estimated. can applied factor scores in analysis or ability item response theory, without bootstrap Markov chain Monte Carlo methods. proposed method is valid both number items subjects large. However, simulation results suggest that provides estimates for errors abilities even numbers

We study the problem of model selection in Bayesian factor analysis. propose a new criterion for this model, which is to select that number factors maximizes posterior probability factors. Equivalently, models with different numbers can be compared by means evaluating odds, or log pairs particular interest. This procedure improves upon use AJC (the AIC, Akaike Information Criterion was proposed being estimated maximum likelihood methods) and BIC (Bayesian Criterion). simulated numerical...

In behavioral sciences, it is often difficult to execute an experimental study with random assignment. Therefore researchers usually do a quasi-experiment or survey without assignment.However, under these studies the distributions of covariates that would affect dependent variables differ values independent variables.To eliminate influence covariates, various adjustment methods such as analysis covariance have been applied data.Recently new using propensity score proposed by Rosenbaum &...

This study aimed to vertically scale the mathematics and Japanese academic ability tests of Japan Child Panel Survey (JCPS) for elementary school first year students through junior high third (grades 1-9 in U.S.). We used an anchoring test design based on item response theory. Two samples were used: JCPS participants (n = 3,916) 7,210). After estimating parameters with a two-parameter logistic model, equating coefficients estimated Haebara method. The scaled fifth (grade 5) end. number items...

The purpose of this paper is to clarify the conditions data, under which direct application factor analysis ordered categorical data may not be appropriate. For purpose, we conducted two simulation studies, in numbers observations, items, categories and factors were systematically changed, methods for estimating correlations used. In these simulations, examined effects various on reproducibility true loadings number factors, frequency improper solutions. Based results, several practical...

This paper broadens earlier Bayesian statistical procedures for problems in the multivariate analysis of variance and covari- ance which were developed general families prior distribu- tions. In this paper, we assume that populations are exchangeable, sense joint probability dis- tribution their parameters is invariant under permutation mean vectors (given dispersion matrices same) By using exchangeability assumption problem assessing hyperparameters substantially reduced. Under vague...
