This journal focuses less on rhythmic articles than it does on emotional aspects of music cognition, such as music and emotion, music and expertise learning, music and social development, etc. However, when it does discuss rhythmic cognition (for an example, see the March 2013 issue and its discussions about how expert musicians treat temporal structure), it does it thoroughly in a scientific way, not necessarily intended for the lay person.
However, the very articles are scattered in topic, and it’s difficult to narrow down on one concept in particular. Also, these articles are predominantly centered in psychological research, and not all of the psychologists presenting work are musicians. I would be surprised if all of these articles (though to be fair, I’ve only read about five so far), really had a very accurate take on how music can be used in all of these discussions.
