Gonzalez, Sandy L.; Campbell, Julie M.; Marcinowski, Emily C.; Michel, George F.; Coxe, Stefany; Nelson, Eliza L. – Developmental Psychology, 2020
Prior work has found links between consistency in toddler handedness for the fine motor skill role-differentiated bimanual manipulation (RDBM), and language development at 2 and 3 years of age. The current study investigated whether consistency in handedness from 18 to 24 months (N = 90) for RDBM predicts receptive and expressive language…

Chen, Jinglu; Tan, Ling; Liu, Lu; Wang, Ling – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2021
It has been demonstrated that the Simon effect may be increased or reversed due to proportion congruency manipulation, suggesting that learned spatial irrelevant stimulus-response (S-R) associations are used to guide responses. In this study, we tested the hypothesis that learning spatial irrelevant S-R associations by rewards may show a similar…

Lyle, Keith B.; Hanaver-Torrez, Shelley D.; Hacklander, Ryan P.; Edlin, James M. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2012
Research has shown that consistently right-handed individuals have poorer memory than do inconsistently right- or left-handed individuals under baseline conditions but more reliably exhibit enhanced memory retrieval after making a series of saccadic eye movements. From this it could be that consistent versus inconsistent handedness, regardless of…

Geuze, Reint H.; Schaafsma, Sara M.; Lust, Jessica M.; Bouma, Anke; Schiefenhovel, Wulf; Groothuis, Ton G. G. – Neuropsychologia, 2012
Considerable variation in the frequency of left-handedness between cultures has been reported, ranging from 0.5 to 24%. This variation in hand preference may have evolved under natural or cultural selection. It has been suggested that schooling affects handedness but as in most human societies only a selected and minor part of the population does…
