In right-handers, the ability to reproduce proprioceptive targets has been shown to be asymmetric, favoring the non-preferred left arm. The present study sought to determine whether a similar arm/hemisphere asymmetry exists for left-handers. Ten strong left-handed adults used the left or right arm to perform proprioceptive target matching tasks that varied in processing demands (i.e., need for memory, interhemispheric transfer) and target amplitude (20, 40 degrees). Similar to right-handers, left-handed individuals had smaller total errors when matching with the non-preferred arm. This asymmetry was greatest in conditions with increased processing demands and larger amplitude targets. These results provide the first evidence to date of right arm/left hemisphere dominance for proprioceptive target matching in left-handers that is the "mirror image" of right-handers.
Given that today's children are prolific users of the internet, concern has been raised about the future impact of the digital footprints they are currently generating. Here we report on the Best Footprint Forward project which utilised focus groups to investigate the digital footprint awareness of thirty-three children (ranging in age from 10 to 12 years old) from three primary schools in regional Australia. The children were very aware of their digital footprints and cyber safety but had little awareness of the positive potential of digital footprints. Instead they exercised their agency through the use of strategies to minimise their digital footprint. We offer an alternative perspective to the dominant discourse that insists that a digital footprint is primarily a liability and seek to counter the positioning of children as naïve, passive consumers of digital culture. We conclude that 10-12 years old is an appropriate age to begin to educate for positive digital footprint curation as this would build on children's demonstrated knowledge of cyber safety and supplement their existing digital footprint management strategies with beneficial alternatives.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
