“…Conversely, right handers used their right hand 82% of the time and 76% of the time for grasping Lego TM and puzzle pieces respectively. The implication here is that left handers use their non-dominant hand more often, and are not mirror images of right handers, which is contrary to findings in other experiments where right and left handers have displayed similar patterns of dominant hand choice (Bishop, Ross, Daniels & Bright, 1996;Bryden, Pryde & Roy, 2000;Calvert & Bishop, 1998). Harris and Carlson (1993) performed a grasping choice experiment with a large number of dextral and adextral adults and children.…”

“…The WHQ was administered before beginning the puzzle task. Because handedness questionnaires can be highly subjective as they rely on participants' comprehension and memory (Bryden et al, 2000), participants were instructed to mime the actions in question so that a more accurate answer could be given. Scores were totalled and ranged from -30 to +30, where negative scores indicated left-hand preference and positive scores indicated right-hand preference.…”

Much debate in the handedness literature has centred on the relative merits of questionnaire-based measures assessing hand preference versus simple movement tasks such as peg moving or finger tapping, assessing hand performance. A third paradigm has grown in popularity, which assesses choices by participants when either hand could be used to execute movements. These newer measures may be useful in predicting possible "reversed" asymmetries in proportions of non-right handed ("adextral") people. In the current studies we examine hand choice in large samples of dextral (right handed) and adextral participants. Unlike in some previous experiments on choice, we found that left handers were as biased towards their dominant hand as were right handers, for grasping during a puzzle-making task (study 1). In a second study, participants had to point to either of two suddenly appearing targets with one hand or the other. In study 2, left handers were not significantly less one handed than their right-handed counterparts as in study 1. In a final study, we used random effects meta analysis to summarise the possible differences in hand choice between left handers and right handers across all hand choice studies published to date. The meta analysis suggests that right handers use their dominant hand 12.5% more than left handers favour their dominant hand (with 95% confidence that the real difference lies between 7 and 18%). These last results suggests that our two experiments reported here may represent statistical Type 2 errors. This mean difference may be related to greater left hemispheric language and praxic laterality in right handers. Nevertheless, more data are needed regarding the precise proportions of left and right handers who favour their preferred hands for different tasks.

“…In deaf adults, a right-sided bias has been reported for signing (e.g., Grossi et al, 1996;Vaid et al, 1989), which may be viewed in relation to neuroimaging data showing that Broca's area is activated in the production of sign language (e.g., Corina et al, 2003;Emmorey et al, 2007). In hearing adults, one study has reported a right-sided asymmetry for pointing gestures (Bryden et al, 2000), however, the pointing task used in that study did not involve any communicative intention (participants were asked to point to an object indicated by the experimenter, without any specific communicative motive). So for now, no data are available for intentional communicative gestures produced by hearing adults.…”

“…In human adults, Bryden et al (2000) examined hand preferences for different unimanual actions, including grasping and pointing towards small objects in different regions of hemispace. The authors failed to observe any difference in the frequency of right hand use across the different tasks, but did not investigate correlations between the tasks.…”

“…Further analyses revealed a significant, but moderate, correlation in right-handers only, reflecting less clearly lateralized patterns in left-handed and ambidextrous participants. Other studies have also reported weak correlations (explaining less than 25% of the variance) between self-reported measures of handedness and more direct task-oriented measures (e.g., Bryden et al, 2000;Cavill and Bryden, 2003). It has been argued that these two methods may assess different aspects of hand preference, the hypothesis being that the questionnaire data reflect a more cognitive component (e.g., implying memory processes) and direct observation of hand use an immediate motor component (Cavill and Bryden, 2003).…”

The present study aimed to examine the relationship between hand dominance and the presence or absence of the flexor digitorum superficialis (FDS) in the fifth digit to add to the current body of knowledge. We hypothesized that the absence of the FDS in the right small finger is more prevalent in left-handed individuals. This was a prospective study conducted from January 2020 to April 2021 and performed at the plastic surgery department of a university hospital. The sample consisted of volunteers with no history of upper limb trauma, surgery, or any other condition. The study included male and female individuals over 18 years old at a local Rhode Island university campus. The FDS tendons of the bilateral fifth fingers were evaluated through clinical testing by an independent examiner. A total of 236 hands from 118 volunteers were analyzed. Left-hand dominant participants composed of 5% of the population. For these participants, the prevalence of absence of the fifth finger FDS tendon in the right hand was significantly higher than that of right-hand dominant participants (71.4% vs. 28.8%). No significant difference between sex assigned at birth (male vs. female) was noted and the absence of the FDS in either hand, regardless of hand dominance. The results from the current study demonstrate that anatomy may contribute to one's preference for left-handedness. For children who have difficulty using their right hand, perhaps, an assessment of their FDS status may result in earlier acceptance of using their left hand.
