We discuss 3 methodological issues involved in climate-population dynamics research. Precise alternative hypotheses are the first requirement, and correlational studies are the weakest way to test the multiple working hypotheses required. Large-scale effects are difficult to investigate because of heterogeneity in environmental variables, and long-term predictions require more patience to test ...

In the last decade, new models of human intelligence have altered the theoretical landscape in psychometrics and cognitive science. In the current article, we provide an overview of key distinguishing features of these new models. Compared to 20th century models of intelligence, the new models proposed in the 21st century are unique for three primary reasons; (1) new models interpret the genera...

This paper proposes distinctions between guilt and two forms of shame: guilt arises from a violated norm and is characterised by a focus on specific behaviour; shame can be characterised by a threatened social image (Image Shame) or a threatened moral essence (Moral Shame). Applying this analysis to group-based emotions, three correlational studies are reported, set in the context of atrocities...

Previous correlational research indicates that adolescent girls who use social network sites more frequently are more dissatisfied with their bodies. However, we know little about the causal direction of this relationship, the mechanisms underlying this relationship, and whether this relationship also occurs among boys to the same extent. The present two-wave panel study (18 month time lag) amo...

Four studies document and explore the psychology underlying people’s proclivity to connect people to each other—to play ‘‘matchmaker.’’ First, Study 1 shows that chronic matchmaking is associated with higher well-being. Studies 2 and 3 show that matching others on how well they will get along increases happiness and is more intrinsically rewarding than other tasks (e.g., deciding which people w...

Previous research has shown how, why, and for whom violent video game play is related to aggression and aggression-related variables. In contrast, less is known about whether some individuals are more likely than others to be the target of increased aggression after violent video game play. The present research examined the idea that the effects of violent video game play are stronger when the ...

The authors propose that the experience of flow (Csikszentmihalyi, 2000) as reflected in the deep involvement in an activity perceived as intrinsically rewarding represents a regulatory compatibility experience. The research addresses the notion that the compatibility of critical person (e.g., skills) and environmental factors (e.g., demands) involved in a given activity elicits subjective expe...
