The doyen of applied behaviourists Patricia McConnell revived a post from 2010 with an interesting link to an article about human movement.
When light points are used to delineate major joints so that the observer only sees a collection of lights, the human brain not only perceives a whole human but can ascribe male or female attributes with a high degree of accuracy. Whilst that is not too surprising, whether male or female, observers reported that figures perceived to be male always appeared to be approaching but those perceived as female were waking away.
This may shed more light (pardon the pun) on the oft-reported phenomenon that some dogs are less comfortable with men than women. Generally, it has been thought that it may be due to men being taller and larger and having deeper voices but perhaps it is also gait?
Many people intimidate dogs by their direct approach; I have lost count of the number of people who have told me that “Dogs love them” as they loom over a flinching dog, hand over the face. We owe it to dogs to be considerably more conscious of the effect that our physicality has them and maybe now we have another tool in the box to help male dog owners.
