Our Observatory has published many articles of the objective differences in the brain between males and females showing that it is not a mere matter of different behaviors (read HERE).

We said in a previous special report, “For decades, scientists have analyzed the brains of both sexes in an attempt to define different traits that might explain this variability. The simple observation of anatomical differences was, until recently, the only evidence to ascertain the causes of sex-differentiated behavior. However, new neuroimaging techniques, which provide valuable information on the functioning of our brain beyond its structure, and even the way in which the neural networks that form it are connected, are bringing a new perspective to explain the bases of these differences.”

In this respect a recent article published in Nature – Scientific reports makes a new approach in sex differences in human cognition. In accord with the authors, “There is a growing interest in sex differences in human and animal cognition. However, empirical evidence supporting behavioral and neural sex differences in humans remains sparse […] the study offers a robust and naturalistic empirical framework to visuo-oculo-manual motor track (visuomotor tracking) in a large group of human participants that consist of tracking with the hand a target moving unpredictably.”

Why do they focus their large investigation on this particular issue? ” […]Sex differences have been reported in various tasks ranging from cognitive to perceptual and motor tasks. Thus, incorporating sex as a biological variable is increasingly proven relevant in behavioral and cognitive neuroscience. However, the nature of these differences remains controversial and their origin is largely unknown.”

They report a clear male advantage in hand tracking accuracy. The article proposed […]”that the male advantage for visuomotor tracking does not reside in a more reliable gaze strategy, or in more sophisticated hand movements, but rather in the faster decisional process linking visual information about target motion with forthcoming hand, but not eye, actions.”

Incorporating sex biological variable in many fields

The aforementioned study suggests: “More generally there is a growing interest in sex differences in funding agencies, the neuroscience community, as well as in medicine for drug treatment and rehabilitation strategies. The current study reinforces the view that incorporating sex as a biological variable is relevant in behavioral neuroscience.” Read HERE

From a bioethical point the view this study shows that differences between males and females should be considered as a fact also in different fields as diagnostics, investigations, education, jobs, and sports.
