Purpose: Vocal fold nodules (VNs) are bilateral, symmetrical, callous-like lesions secondary to phonotrauma and possibly related to specific personality traits. This case-control study examined the relation between personality and VNs in children within the context of the Trait Theory of VNs. Method: Parents of children with VNs (N = 39, M = 7.43,…

The foreign and second language (L2) learning process is shaped by a constellation of individual difference (ID) factors, some of which (e.g., age, anxiety, motivation, aptitude, learning styles, language learning strategies) have long been investigated by specialists, whereas others have only recently attracted their attention. One of such…

The objective of the article is the correspondence of individual and typological features of the student to the chosen direction, which promotes successful adaptation to study at the university and readiness for future professional activity. The aim is to reveal psychological features of personality of students: doctors, engineers, and jurists.…

We investigated how positive, negative, and neutral mood states influence aspects of second language acquisition, either directly or in interaction with certain personality characteristics (openness, intuition, emotional intelligence, foreign language anxiety, and impulsivity). After completing individual differences questionnaires, 120…

According to models of differential susceptibility, the same neurobiological and temperamental traits that determine increased sensitivity to stress and adversity also confer enhanced responsivity to the positive aspects of the environment. Differential susceptibility models have expanded to include complex developmental processes in which genetic…

A sample of 168 bishops, serving or retired, in the Church of England completed the Francis Psychological Type Scales. The psychological type profile of these bishops was compared with that of 626 Anglican clergymen. The bishops differed significantly from the clergymen on three of the four aspects of psychological type. The bishops were more…

We investigated two factors that predict students' achievement and behaviour in undergraduate mathematics: gender and personality. We found that gender predicted students' achievement and behaviour when considered in isolation, but ceased to be predictive when personality profiles were taken into account. Furthermore, personality accounted for…

This article describes an exploration of the distinction between typological and factorial latent variables in the domain of personality theory. Traditionally, many personality variables have been considered to be factorial in nature, even though there are examples of typological constructs dating back to Hippocrates. Recently, some…

Data provided by 5,402 students recruited from…

Previous research has highlighted the important role of choice in listeners' responses to music, but relatively little is known about the subjective criteria on which listeners base their choices. Hence, the goal of this study was to make a first attempt to investigate the relative importance of various criteria in listeners' choice and aesthetic…

Human subject pools (HSPs) are the basis for much psychological research. There is an explicit assumption that participants receive benefits from their participation, however there is little empirical research about the costs/benefits of participation. We conducted two studies with undergraduate psychology students to evaluate factors that can…

Temperament is important for considering differences among diagnostic groups and for understanding individual differences that predict problematic behavior. Temperament characteristics, such as negative affectivity, effortful control, and surgency (highly active and impulsive), are predictive of externalizing behavior in typically developing…

Intra-individual variability over a short period of time may contain important information about how individuals differ from each other. In this article we begin by discussing diverse indicators for quantifying intra-individual variability and indicate their advantages and disadvantages. Then we propose an alternative method that models…
