Handedness differences observed in episodic memory retrieval do not extend to the domain of prospective memory

Differences Between Consistent and Inconsistent Handedness Remain Consistently Interesting: Ten Years of Research on the Consistency of Handedness With the Edinburgh Handedness Inventory

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.

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.
