Some researchers indicate that the transition to high school deflects adolescent developmental trajectories. Others assert that it provides a new possibility for the promotion of adolescents' socioemotional well-being. One critical view missing in such claims is that individual variabilities interact with environmental influences. We employed the…

'Grit' has been identified as an important predictor of success in a number of academic and non-academic domains (Duckworth, A. L., C. Peterson, M. D. Matthews, and D. R. Kelly. 2007. "Grit: Perseverance and Passion for Long-Term Goals." "Journal of Personality and Social Psychology" 92: 1087-1101.…

According to several developmental theories some children are more sensitive to the quality of their environment than others, but most supporting empirical evidence is based on relatively distal markers of hypothesized sensitivity. This study provides evidence for the validity of behaviorally observed Environmental Sensitivity as a moderator of…

On empirical and theoretical grounds, it is proposed that the enjoyment of reading, and particular reading interests, relate to people's individuality. This research used photo essays about the self as the method for operationalizing individuality--that is, self-construals that are unlike others (i.e. are uniquely self-reflective,…

In this article, we present an analysis of individual factors that influence how well a person can read and understand a text in an unfamiliar, but closely related language--the basis of the so-called teaching of intercomprehension. Our work analyzes these relations from two normally separate perspectives. The first perspective focuses on how…

Epistemic curiosity (EC) is the desire to obtain new knowledge capable of either producing positive experiences of intellectual interest (I-type) or of reducing undesirable conditions of informational deprivation (D-type). Although researchers acknowledge that there are individual differences in young children's epistemic curiosity, there are…

The Personality Psychopathology-Five (PSY-5; Harkness & McNulty, 1994) is a model of individual differences relevant to adaptive functioning in both clinical and non-clinical populations. In this article, we review the development of the PSY-5 model (Harkness, 1992; Harkness & McNulty, 1994) and discuss the ways in which the PSY-5 model is…

This article analyzes latent variable models from a cognitive psychology perspective. We start by discussing work by Tuerlinckx and De Boeck (2005), who proved that a diffusion model for 2-choice response processes entails a 2-parameter logistic item response theory (IRT) model for individual differences in the response data. Following this line…

This article seeks to unify two subfields of psychology that have hitherto stood separately: evolutionary psychology and intelligence research/differential psychology. I suggest that general intelligence may simultaneously be an evolved adaptation and an individual-difference variable. Tooby and Cosmides's (1990a) notion of random quantitative…

The social accuracy model of interpersonal perception (SAM) is a componential model that estimates perceiver and target effects of different components of accuracy across traits simultaneously. For instance, Jane may be generally accurate in her perceptions of others and thus high in "perceptive accuracy"--the extent to which a particular…

We are grateful to the commentators for providing many stimulating and valuable observations. The main point of our article was to call attention to the overestimation of individual differences correlations in a subset of neuroimaging papers. To structure our discussion of these comments, we list the main points from our paper, note where…

Background: Both ability (measured by power tests) and non-ability (measured by preference tests) individual difference measures predict academic school outcomes. These include fluid as well as crystalized intelligence, personality traits, and learning styles. This paper examines the incremental validity of five psychometric tests and the sex and…

We are delighted to welcome you to the International Psychological Applications Conference and Trends (InPACT) 2017, taking place in Budapest, Hungary, from 29 of April to 1 of May, 2017. Modern psychology offers a large range of scientific fields where it can be applied. The goal of understanding individuals and groups (mental functions and…

Three studies, all on student populations, looked at the relationship between a recently psychometrised measure of General Knowledge [Irwing, P., Cammock, T., & Lynn, R. (2001). Some evidence for the existence of a general factor of semantic memory and its components. "Personality and Individual Differences," 30, 857-871], both long…

We are delighted to welcome you to the International Psychological Applications Conference and Trends 2014, taking place in Porto, Portugal, from 4 to 6 of April. Psychology, in our time, offers a large range of scientific fields where it can be applied. The goal of understanding individuals and groups (mental functions and behavioral…
