Laterality indices consensus initiative (LICI): A Delphi expert survey report on recommendations to record, assess, and report asymmetry in human behavioural and brain research Laterality (IF 2.167) Pub Date : 2023-05-21 Guy Vingerhoets, Helena Verhelst, Robin Gerrits, Nicholas Badcock, Dorothy V. M. Bishop, David Carey, Jason Flindall, Gina Grimshaw, Lauren Julius Harris, Markus Hausmann, Marco Hirnstein, Lutz Jäncke, Marc Joliot, Karsten Specht, René Westerhausen, LICI consortium
ABSTRACT Laterality indices (LIs) quantify the left-right asymmetry of brain and behavioural variables and provide a measure that is statistically convenient and seemingly easy to interpret. Substantial variability in how structural and functional asymmetries are recorded, calculated, and reported, however, suggest little agreement on the conditions required for its valid assessment.

ABSTRACT Stress exposure and reactivity may show differential associations with handedness, but shallow phenotyping may influence the current knowledge. Importantly, different handedness measures do not necessarily show high correlations with each other and should not be used interchangeably as they may reflect different dimensions of laterality. Here, data on handedness from 599 participants in the

Righteous Adam, Sinister Eve Laterality (IF 2.167) Pub Date : 2022-11-30 Sergio Della Sala, Robert D. McIntosh
ABSTRACT The symbolism of laterality in images implies that the virtuous figure is represented on the right of the scene whereas the sinful character is depicted on the left. In portraits of male and female characters this has reflected and reinforced stereotypes and inequalities down the ages. Given these premises, we hypothesized that the prototypical representations of Adam and Eve, as a man and

ABSTRACT Studies have highlighted an association between motor laterality and speech production laterality. It is thought that common demands for sequential processing may underlie this association. However, most studies in this area have relied on relatively small samples and have infrequently explored the reliability of the tools used to assess lateralization. We, therefore, established the validity

A longitudinal examination of perinatal testosterone, estradiol and vitamin D as predictors of handedness outcomes in childhood and adolescence Laterality (IF 2.167) Pub Date : 2022-08-06 Gareth Richards, Diana Weiting Tan, Andrew J. O. Whitehouse, I. Chris McManus, Alan A. Beaton, Martha Hickey, Murray T. Maybery, Melissa K. Licari, Lauren Lawson
ABSTRACT The developmental origins of handedness remain elusive, though very early emergence suggests individual differences manifesting in utero could play an important role. Prenatal testosterone and Vitamin D exposure are considered, yet findings and interpretations remain equivocal. We examined n = 767 offspring from a population-based pregnancy cohort (The Raine Study) for whom early biological

Who goes where in couples and pairs? Effects of sex and handedness on side preferences in human dyads Laterality (IF 2.167) Pub Date : 2022-06-21 Paul Rodway, Astrid Schepman
ABSTRACT 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

Identifying spatial effects in a lateralized duration estimation task Laterality (IF 2.167) Pub Date : 2021-08-15 Corinna D. McFeaters, Daniel Voyer
ABSTRACT Spatial influences may be introduced to an experimental task by manipulations performed on the stimulus or the response or by virtue of the type of stimuli under study. Identification of spatial influences is especially pertinent in investigations of laterality, as isolation of processing to one hemisphere may inadvertently introduce spatial confounds. Because, however, space is not a relevant

Laterality of motor symptom onset and facial expressivity in Parkinson disease using face digitization Laterality (IF 2.167) Pub Date : 2021-07-05 Adrianna M. Ratajska, Anne N. Nisenzon, Francesca V. Lopez, Alexandra L. Clark, Didem Gokcay, Michael S. Okun, Dawn Bowers
ABSTRACT The onset of motor symptoms in Parkinson disease (PD) is typically unilateral. Previous work has suggested that laterality of motor symptoms may also influence non-motor symptoms including cognition and emotion perception. In line with hemispheric differences in emotion processing, we tested whether left side/right brain motor onset was associated with worse expression of facial affect when
