Genetic and environmental structure of individual differences in hand, foot, and ear preferences: a twin study.
We examined the genetic and environmental factors for hand, foot, and ear preferences using a twin design study. A lateral preference questionnaire was administered to twin participants (N=956). Phenotypic correlation matrices of lateral preferences were computed for monozygotic and dizygotic twin p...
The influence of left and right hemisphere brain damage on configural and featural processing of affective faces.
The literature about the lateralization of facial emotion perception according to valence (positive, negative) is conflicting; investigating the underlying processes may shed light on why some studies show right-hemisphere dominance across valence and other studies demonstrate hemispheric difference...
How do incorrect results change the processing of arithmetic information? Evidence from a divided visual field experiment.
These results reveal a clear differential processing of arithmetic information by the two cerebral hemispheres with a special emphasis on erroneous calculations. Faced with incorrect results and with a consistent numerical notation, the left hemisphere outperforms its right counterpart in making mat...
Response format, magnitude of laterality effects, and sex differences in laterality.
The present study examined the evidence for the claim that response format might affect the magnitude of laterality effects by means of a meta-analysis. The analysis included the 396 effect sizes drawn from 266 studies retrieved by Voyer (1996) and relevant to the main effect of laterality and sex d...
The relation between lateralisation, early start of training, and amount of practice in musicians: a contribution to the problem of handedne...
This study investigates the influence of extensive bimanual training in professional musicians on the incidence of handedness in the most basic form of right-handedness (RH) and non-right-handedness (NRH), according to Annett's "right shift theory". The lateralisation coefficients (LCs) of a total s...
Optic chiasm in the species of order Clupeiformes, family Clupeidae: optic chiasm of Spratelloides gracilis shows an opposite laterality to ...
We report our findings that Spratelloides gracilis, of the order Clupeiformes, family Clupeidae, shows a particular laterality of decussation: the left optic nerve ran dorsally to the right (n=200/202). In contrast, Etrumeus teres, of the same order and family, had a strong preference of the opposit...
Manual asymmetry in a complex coincidence-anticipation task: handedness and gender effects.
This study investigated the effects of handedness and gender on manual asymmetry in the performance of a complex coincidence-anticipation task. Left-handed (N=63) and right-handed (N=93) undergraduate students (78 males, 78 females) were required to press six buttons sequentially in conjunction with...
Light exposure during incubation and social and vigilance behaviour of domestic chicks.
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 preda...
Dual-task performance in late proficient bilinguals.
A dual task, consisting of speeded tapping during concurrent silent and aloud reading, was employed to investigate hemispheric specialisation for both first (L1) and second (L2) language in late proficient bilinguals living in the L2 environment. Overall, bilinguals and matched monolinguals showed m...
Is left-handedness associated with a more pronounced age-related cognitive decline?
We evaluated the effect of handedness on age-related decline in four major cognitive domains: speed of information processing, verbal learning, long-term verbal memory, and executive functioning. The results failed to provide support for the hypothesis that sinistrality is associated with a more pro...
