HighlightsSystematic review of 36 studies (66,108 individuals) measuring full IQ scores.Three sets of meta‐analyses including data on 20,442 individuals.Marginal differences in mean IQ scores detected between right‐ and left‐handers.Negligible difference in favor of right‐handers. ABSTRACT The relationship between intelligence and handedness remains a matter of debate. The present study is a systematic review of 36 studies (totaling 66,108 individuals), which have measured full IQ scores in… 
Human handedness: A meta-analysis.
TLDR
It is argued that the same evolutionary mechanisms should apply across geographical regions to maintain the roughly 1:10 ratio, while cultural factors, such as pressure against left-hand use, moderate the magnitude of the prevalence of left-handedness.
Handedness and cognitive ability: Using meta-analysis to make sense of the data.
TLDR
It is here suggested that degree ofhandedness and hand skill measures are employed in future studies exploring the possible relationship between handedness and cognitive ability so as to elaborate whether or not such a relationship exists and if so, what its characteristics are.
Hand preference and Mathematical Learning Difficulties: New data from Greece, the United Kingdom, and Germany and two meta-analyses of the literature
TLDR
It is suggested that potential handedness effects require larger samples, direction of hand preference is not a sensitive enough measure of handedness in this context, or that increased rates of atypical hand preference are not associated with MLD.
Cerebral laterality for writing in right- and left-handers: A functional transcranial Doppler ultrasound study
TLDR
Findings suggest that, in right-handers, the linguistic aspect of written word generation recruited left-hemispheric areas during writing, similarly to oral language production, and the greater variability in cerebral laterality patterns within left- handers or the attentional demands of symbol copying could explain the different findings.
Cognitive sex differences and hemispheric asymmetry: A critical review of 40 years of research
TLDR
A systematic literature review showing that cognitive sex differences often emerge in the absence of sex differences in hemispheric asymmetry, implying the two phenomena are at least partly independent of each other.
"I am a lefty in a right-handed world": Qualitative analysis of clinical learning experience of left-handed undergraduate dental students.
TLDR
Left-handed students have a strong sense of adaptability, however, in order to improve the learning experience regardless of the difference in the operator's preference of dominant hand, students should be provided with appropriate equipment such as ambidextrous dental chairs and professional guidance, especially during their early career.
Developmental Laterality Research: Childhood
  • G. Young
  • Psychology
    Causality and Development
  • 2019
The second chapter on early laterality continues with research on children; and the same patterns are found as for infancy – the right hand exhibits a manual preference/handedness – but there are
Clinical correlates of laterality among school-age children in the United States
TLDR
In this large, longitudinal study of neurologically healthy children, modest associations were observed between hand/eye preference and IQ and hyperactivity only.
Laterality 2020: entering the next decade
TLDR
Which trends are likely to shape laterality research in the 2020s include, but are not limited to, finding laterality-specific solutions to the replication crisis, and integrating non-W.E.I.R.D. samples intoLaterality research to a larger extent.
Triplets, birthweight, and handedness
TLDR
In both samples of triplets, it was showed that left-handedness was associated with lower birthweight, and the results suggest that developmental differences between left- and right-handers are due to a shared etiology associated with low birthweight.

Cognitive benefits of right-handedness: A meta-analysis
TLDR
There is a small but significant cognitive advantage of right-handedness on spatial ability and in the verbal domain, this advantage is only significant in children and an interaction effect with sex is not confirmed.
Intelligence and handedness: Meta-analyses of studies on intellectually disabled, typically developing, and gifted individuals
TLDR
Elevated levels of atypical handedness were found to be robust only for the ID to TD comparison, constrain the range of acceptable theories on the handedness distribution for different intelligence levels.
Elevated Levels of Atypical Handedness in Autism: Meta-Analyses
TLDR
Three sets of meta-analyses of studies that assessed the handedness prevalence among individuals with ASD revealed a trend towards weaker handedness for individuals with Autism Spectrum Disorder, which could be attributed to atypicalities in cerebral structure and lateralization for language in Individuals with ASD.
Sex differences in left-handedness: a meta-analysis of 144 studies.
TLDR
The results of which demonstrate that the sex difference is both significant and robust, and its observed magnitude places an important constraint on current theories of handedness.
The relationship between hand preference, hand performance, and general cognitive ability
TLDR
It is demonstrated that handedness is related to cognitive ability, and the effects are subtle and might only be identified in large-scale studies with sensitive measures of hand performance.
Cerebral lateralization of praxis in right‐ and left‐handedness: Same pattern, different strength
TLDR
It is concluded that the recollection and pantomiming of learned gestures recruits a similar left lateralized activation pattern in right and left‐handed individuals, pointing to a lesser hemispheric specialization in left‐handers that may be considered in the cost/benefit assessment to explain the disproportionate handedness polymorphism in humans.
Handedness prevalence in the deaf: Meta-analyses
TLDR
Four sets of meta-analyses on studies measuring handedness prevalence in deaf individuals are presented to suggest that the higher prevalence of atypical handedness in the deaf population may be linked to delayed language acquisition.
Autism, lateralisation, and handedness: A review of the literature and meta-analysis
TLDR
Although the results are not conclusive, there appears to be a trend towards a relationship between autism and lateralisation, however, more rigorous studies with better controls and clearer reporting of definitions and results are needed.
The disadvantages of dextrality for intelligence.
TLDR
Strong dextrality is associated with weak left-hand skill, not good right- hand skill, in accord with the hypothesis that the costs of RS are to the right hemisphere, and for their implications for theories of hemisphere specialization.
