- Indications of laterall biases favouring left-handers have been found in various sports; especially interactive sports where the athletes have limited time to react to incoming objects. The aim of this study was therefore to explore whether any lateral biases exist in handball by examining 7-meter shots. A total of 6846 7-meter throws from 240 7-meter shooters across four seasons in the semi-professional Icelandic elite handball division (male and female) were analyzed. Out of the 240 7-meter shooters, of which 151 were male and 89 were female, 22% were left-handed (22% of the males and 20% of the females). The left-handed 7-meter shooters took a disproportionate number of the 7-meter shots, with left-handed shooters performing 29% of the 7-meter shots (27% in the male league and 33% in the female league). The results of a Bayesian two-level analysis indicated that left-handedness is not associated with greater success from the 7-meter line at the semi-professional level. © 2023 The Author(s).

Non-replication of an association of Apolipoprotein E2 with sinistrality

- A recent report found that left-handed adolescents were more than three times more likely to have an Apolipoprotein (APOE) E2 allele. This study was unable to replicate this association in young adults (N=166). A meta-analysis of nine other datasets (N=360 to 7559, Power > 0.999) including that of National Alzheimer's Coordinating Center also failed to find an over-representation of E2 among left-handers indicating that this earlier outcome was most likely a statistical artefact.

Light exposure during incubation and social and vigilance behaviour of domestic chicks

- Light exposure of chick eggs during a sensitive period at the end of the incubation period leads to the development of lateralised visual behaviour, and here we show that social behaviour is also influenced by this exposure. Groups of eight chicks of three types(1) all incubated in the dark (Da), (2) all exposed to light (Li), (3) half Da and half Li (Mixed)were tested on a range of tasks involving social competition and vigilance for a simulated predator. We confirmed a previous finding that lowest-ranking chicks in Li groups gained less access to a food bowl when they had to compete with group members than did the lowest-ranking chicks in the Da groups, and we extended this result to show that the Mixed groups performed like the Li groups. We also showed that before presentation of a novel stimulus resembling a predator, fewer of the chicks in the Da groups than in the Li and Mixed groups looked up, but during presentation of the predator more Da than Li chicks looked up. Hence, light exposure before hatching affects post-hatching social and vigilance behaviour.
