Higher education students' perceptions of ChatGPT: A global study of early reactions.

The paper presents the most comprehensive and large-scale global study to date on how higher education students perceived the use of ChatGPT in early 2024. With a sample of 23,218 students from 109 countries and territories, the study reveals that students primarily used ChatGPT for brainstorming, summarizing texts, and finding research articles, with a few using it for professional and creative writing. They found it useful for simplifying complex information and summarizing content, but less reliable for providing information and supporting classroom learning, though some considered its information clearer than that from peers and teachers.

Who goes where in couples and pairs? Effects of sex and handedness on side preferences in human dyads.

There is increasing evidence that inter-individual interaction among conspecifics can cause population-level lateralization. Male-female and mother-infant dyads of several non-human species show lateralised position preferences, but such preferences have rarely been examined in humans. We observed 430 male-female human pairs and found a significant bias for males to walk on the right side of the pair.

Concreteness of semantic interpretations of abstract and representational artworks.

The authors tested two contrasting theoretical predictions to establish whether semantic interpretations of abstract artworks had different lexical concreteness from those of representational artworks. In Experiment 1, 49 non-expert participants provided brief verbal interpretations of 20 abstract and 20 representational artworks. Frequentist and Bayesian Linear Mixed Models showed that the words' concreteness levels were robustly higher for interpretations of abstract artworks than representational artworks.

A leftward bias for the arrangement of consumer items that differ in attractiveness.

People are frequently biased to use left-side information more than right-side information to inform their perceptual judgements. This research examined whether the leftward bias also applied to preferences for the arrangement of everyday consumer items. Pairs of consumer items were created where one item was more attractive than the other item.
