This study examined if personality types of gifted students predicted their psychiatric symptoms and if the type of giftedness and gender moderated the relationship between the personality and psychiatric manifestations. "The Murphy-Meisgeir Type Indicator for Children" and "the Minnesota Multiphasic Personality…

Adaptive e-learning can be used to personalize learning environment for students to meet their individual demands. Individual differences depend on the students' personality traits. Numerous studies have indicated that understanding the role of personality in the learning process can facilitate learning. Hence, personality identification in…

This study aims to use group technology to classify students at the classroom level into clusters according to their learning style preferences. Group technology is used, due to the realization that many problems are similar, and that by grouping similar problems, single solutions can be found for a set of problems. The Felder and Silverman style,…

Large-scale assessments are supported by a large item pool. An important task in test development is to assign items into scales that measure different characteristics of individuals, and a popular approach is cluster analysis of items. Classical methods in cluster analysis, such as the hierarchical clustering, K-means method, and latent-class…

A study in a university clinic/laboratory investigated adaptive Bayesian scaling as a supplement to interpretation of scores on the Mini-IPIP. A "probability of belonging" in categories of low, medium, or high on each of the Big Five traits was calculated after each item response and continued until all items had been used or until a…

Purpose: The purpose of this study is to develop a model of motives and career choice based on learning styles in order to apply the model in teaching business. Although the relationship between learning and McClelland's (1961) three motives (achievement, affiliation, and power) as confirmed that motives are "learned," little research…

Badge use has rapidly expanded in recent years and has benefited a variety of applications. However, a large portion of the research has applied a binary "useful" or "not useful" approach to badging. Few studies examine the characteristics of the user and the impact of those characteristics on the effectiveness of the badging…

This study assessed differences in Parker's typology of perfectionism (healthy perfectionist, unhealthy perfectionist, and nonperfectionist). We compared the results from previous research with follow-up 2005 and 2010 data collected from highly gifted Czech mathematicians aged 12 to 16 years. The study examined whether the same three…

The purpose of this article was to describe an initial step developing a new scale to identify individuals with learning disabilities (LD) and test anxiety. Eighty-eight students answered the "Minnesota Multiphasic Personality Inventory-2" (MMPI-2). The participants were drawn from the following three groups: (a) adults with LD and test…

Sadistic personality disorder (SPD) has been underresearched and often misunderstood in forensic settings. Furthermore, personality disorders in general are the subject of much controversy in terms of their classification (i.e., whether they should be categorical or dimensional). The Sadistic Attitudes and Behaviors Scale (SABS; Davies & Hand,…

In the current time of globalization, collaboration among people in virtual environments is becoming an important precondition of success. This trend is reflected also in the educational domain where students collaborate in various short-term groups created repetitively but changing in each round (e.g. in MOOCs). Students in these kind of dynamic…

This study examined whether the number of options in the Likert scale influences the psychological distance between categories. The most important assumption when using the Likert scale is that the psychological distance between options is equal. The authors proposed a new algorithm for calculating the scale values of options by applying item…

In an attempt to influence students' appreciation of the value of research, the authors introduced a multidimensional scaling activity in a section of introductory psychology. In two consecutive 80-minute classes, 32 students worked in pairs, categorizing 20 crimes on the basis of similarity and coding their partner's responses, and then worked in…

Objective: Oppositional defiant disorder (ODD) is the most common comorbid condition in childhood ADHD. This trial was prospectively designed to explore ODD symptoms in ADHD adults. Method: A total of 86 patients in this placebo-controlled, double-blind trial of methylphenidate transdermal system (MTS) were categorized based on the presence of ODD…

We examined the utility of the validity scales on the recently released Minnesota Multiphasic Personality Inventory-2 Restructured Form (MMPI-2 RF; Ben-Porath & Tellegen, 2008) to detect overreported psychopathology. This set of validity scales includes a newly developed scale and revised versions of the original MMPI-2 validity scales. We…
