Gender and geographical disparity in editorial boards of journals in psychology and neuroscience

While certain metrics of diversity have seen great improvement in recent years in academic psychology and neuroscience, unequal representation remains for many positions of power. Here, we reviewed publicly available information in order to infer the proportion of editors by gender and their country of affiliation in the top 50 journals worldwide in each of the two fields. The sample included a total of 2,864 editors for psychology journals and 3,093 editors for neuroscience journals. There was a statistically significant difference in the proportion of male and female editors in both fields, both across editorial roles, and within various role categories, including editor-in-chief and their deputies at neuroscience journals, associate and section editors in both fields, and editorial and advisory board members in both fields. The only category in which there was not a significant imbalance of male and female scholars was the editors-in-chief of psychology journals and their deputies. Geographically, USA-based academics significantly outnumbered those from other countries as editors in both psychology and neuroscience. Results also indicated that over three quarters of psychology journals (76%) were comprised of more than 50% male editors, while only 20% had a similar proportion of female editors. In neuroscience, 88% of journals were comprised of more than 50% male editors, while only 10% of journals included a similar, proportional majority of female editors. Findings suggest that editorial positions in academic journals, possibly one of the most powerful decision-making roles in academic psychology and neuroscience, are not balanced in gender or geographical representation.

Relationship between cardiac cycle and the timing of actions during action execution and observation

Previous research suggests that there may be a relationship between the timing of motor events and phases of the cardiac cycle. However, this relationship has thus far only been researched using simple isolated movements such as key-presses in reaction-time tasks and only in a single subject acting alone. Other research has shown both movement and cardiac coordination among interacting individuals. Here, we investigated how the cardiac cycle relates to ongoing self-paced movements in both action execution and observation using a novel dyadic paradigm. We recorded electrocardiography (ECG) in 26 healthy adult subjects who formed 19 dyads (7 comprised of two subjects and 12 subjects paired with an experimenter). Each dyad contained an action executioner and observer as they performed a self-paced sequence of movements. We demonstrated that heartbeats are timed to movements during both action execution and observation. Specifically, movements were less likely to culminate synchronously with the heartbeat, around the time of the R-peak of the ECG. The same pattern was observed for action observation, with the observers heartbeats occurring off-phase with movement culmination. These findings demonstrate that there is coordination between an action executioners cardiac cycle and the timing of their movements, and that the same relationship is mirrored in an observer. This suggests that previous findings of interpersonal coordination may be caused by the mirroring of a phasic relationship between movement and the heart.
