We describe an important class of semideenite programming problems that has received scant attention in the optimization community. These problems are derived from considerations in distance geometry and multidimensional scaling and therefore arise in a variety of disciplines, e.g. computational chemistry and psychometrics. In most applications, the feasible positive semideenite matrices are re...

In the context of the development of prototypic assessment instruments in the areas of cognition, personality, and adaptive functioning, the issues of standardization, norming procedures, and the important psychometrics of test reliability and validity are evaluated critically. Criteria, guidelines, and simple rules of thumb are provided to assist the clinician faced with the challenge of choos...

The question of how observable variables should be associated with latent structures has been at the center area psychometrics. A recently proposed alternative model to traditional factor retention methods is called Exploratory Graph Analysis (EGA). This method belongs broader family network psychometrics which assumes that associations between observed are caused by a system in have direct and...

One of the major contributions of Howard Gardner’s book, Frames of Mind containing the theory of multiple intelligences was an important link between two major approaches to psychology, which were then and for the most part still are, quite separate. First, was an approach to the common mental processes and behavior of human beings and second, was the psychometrics of individual differences imp...

The association between orbital frontal cortex (OFC) volume and aggression and impulsivity was investigated among a heterogeneous group of non-psychotic psychiatric clients. Fifteen non-psychotic subjects from two different psychiatric clinics (New England Medical Center and Lemuel Shattuck Hospital) with a variety of diagnoses were sequentially referred for magnetic resonance imaging (MRI) for...

Analyzing people’s opinions, attitudes, sentiments, and emotions based on user-generated content (UGC) is feasible for identifying the psychological characteristics of social network users. However, most studies focus on identifying the sentiments carried in the micro-blogging text and there is no ideal calculation method for users’ real emotional states. In this study, the Profile of Mood Stat...

Mosaic plots are state-of-the-art graphics for multivariate categor ical data in statistical visualization. Knowledge structures mathematical models that belong to the theory of knowledge spaces psychometrics. This paper presents an application mosaic psychometric arising from underlying structure models. In simulation trials and with empirical data, scope this graphing method space is investig...

Because of increased stress conditions in college students, updated psychometrics of the Perceived Stress Scale, 10-item version (PSS-10; S. Cohen & G. Williamson, 1988) are necessary. Participants were 281 undergraduates at 3 public universities. An exploratory factor analysis revealed a 2-factor structure measuring Perceived Helplessness and Perceived Self-Efficacy. Normative results, interna...

The alignment of sound intensity is of great importance particularly in the field of psychometrics. When sounds have different spectral content, loudness alignment becomes a more suitable tool. However, traditional models assume the source either to reside in a free field at 0° azimuth or in a diffuse field. To assess or align sound source loudness at different locations or with different radia...
