“…Interestingly, the handedness effects accounted for variance above and beyond variance accounted for by other established memory effects observed in the paper, such as the effects of a retroactive interference condition in study one and the effect of context in study two. As with the working memory paper published by Sahu and Christman (2014), inconsistent handedness was shown to be a robust correlate of memory in addition to other factors. If anything, it suggests that every memory study should at least include handedness as a factor, even if it is not the main focus of the study.…”

“…While we caution that a null result is not exactly a disconfirmation of a theory, a replicated null result may still be informative. Sahu and Christman (2014) published a set of studies comparing inconsistent and consistent handers on two measures of prospective memory. In the first study, 105 participants completed a self-report measure of prospective and retrospective memory.…”

Almost 10 years ago Prichard et al. (2013) published a literature review on consistency of handedness. They described how consistency of handedness, typically measured by the Edinburgh Handedness Inventory (EHI), predicted outcomes in memory and decision-making paradigms better than direction of handedness. In the last 10 years, new research has extended these findings and added new theoretical perspectives. The goal of this short form review is to highlight and summarize some of these more intriguing findings and to encourage researchers in the fields of memory and decision making to incorporate handedness as a variable in future research.

“…Though the relationship between handedness and episodic memory performance has been documented, this finding does not generalize to all other memory processes. For instance, there are no handedness differences on tasks of prospective memory because it is thought to rely more prominently on executive functioning (Sahu & Christman, 2014). Handedness group differences have been shown to only affect memory processes that require hemispheric interaction (Lyle, McCabe, & Roediger, 2008), such as word memory tests.…”

Performance validity tests (PVTs) have become an integral part of comprehensive neuropsychological evaluations. Though these measures are purported to be resistant to failure in individuals with brain injury (Larrabee, 2012), research shows that factors other than intentional malingering such as pain, fatigue, and psychological distress may affect performances on these tests when scores are slightly below the reported cut-off (Bigler, 2014;Lezak, Howieson, Bigler, & Tranel, 2012). Given that many of the most commonly used free-standing PVTs are presented as memory tests and some literature has documented superior episodic memory performance in individuals with indeterminate handedness (i.e., at least partially "left-handed"), the current observational, descriptive study investigated the influence of handedness on performance validity test scores. Contrary to expectation, results show that self-identified left-handers in a nonforensic clinical sample of convenience fail the Recognition Memory Test (but not the Word Choice Test) more often than right-handers when using standard cut-off scores. These results raise important questions about whether handedness should play a role in the interpretation of PVTs.

“…Further, those with ICH, compared to those with CH, more accurately recall which hand they use to perform actions (Edlin et al, 2013). Handedness, however, is not associated with all memory types, such as prospective memory (Sahu & Christman, 2014), working memory (Sahu et al, 2016), or face recognition (Lyle, McCabe, et al, 2008). Further, strong right-handedness is associated with decreased interhemispheric interaction and higher rates of false memories (Christman et al, 2004).…”

Interhemispheric Activation and Memory Function: Considerations and Recommendations in the Context of Cardiovascular Exercise Research

The field of neurobiology of learning and memory has demonstrated that interhemispheric activation plays an important role in subserving episodic memory function. A common behavioral technique to induce interhemispheric activation includes saccadic eye movements, with a common behavioral marker being the degree of handedness. Importantly, however, the field of exercise neurobiology has yet to consider these behavioral techniques and markers in exercise-based studies. This review highlights the effects of these techniques and markers on episodic memory function and discusses the implications of this for exercise studies. We discuss the physiological and neurological mechanisms of interhemispheric activation on memory. We also discuss the role this may play in cardiorespiratory exercise studies. Our understanding of the role of both exercise and interhemispheric activation on memory function is improving. The interplay between these two factors on memory, however, is unknown. We discuss these implications and provide recommendations for future research.
