What representations guarantee that you to snatch this apple?
Bence Nanay calls those representations that make sure that you to snatch the apple "pragmatic representations." In Between belief and Action he argues that pragmatic representations whose functionality is to mediate among sensory enter and motor output play an immensely very important position in our psychological existence. and so they support us to give an explanation for why nearly all of what is going on in our brain is especially just like the easy psychological approaches of animals.
The human brain, just like the brain of non-human animals, has been chosen for permitting us to accomplish activities effectively. And nearly all of our activities, just like the activities of non-human animals, couldn't be played with out perceptual counsel. And what presents the perceptual counsel for acting activities are pragmatic representations.

But note that this is only one way of describing this scenario. Another way of doing so would be to say that our perceptual states give rise to another, non-perceptual state, and the mental state that guides our bodily movement is this latter, non-perceptual state. 6 How can we decide between these two ways of describing the scenario? More generally, how can we decide between a perceptual and a nonperceptual account of pragmatic representations? I will argue in the next section that the latter account is inconsistent with an odd fact about perceptual learning.
I need to represent its spatial location, its size, and its weight. Moreover, I need to represent these properties in an action-relevant way: in a way that would help me to pick it up. It would be of no use for the purposes of performing this action if I represented the cup’s weight in pounds or its size in inches—in any case, such a representation would not be necessary for the performance of the action. The representation of the cup’s weight in such a way that would allow me to exert the appropriate force is, in contrast, necessary.
The representation of the cup’s weight in such a way that would allow me to exert the appropriate force is, in contrast, necessary. Further, action-properties are relational properties: they depend both on the object and on my strength, hand size, and spatial position, in this example. To focus on the size-property only, the action-property that is necessary for performing the action of lifting the cup is a relational 40 between perception and action property, the relata of which are the size of the cup and the grip size I would be approaching the cup with, which, in turn, depends on the size of my hand.
