Influence Of Object Action State On Action Suppression Loop

In the past few years there has been an increasing number of studies showing that the perception of objects can get the kind of visual information but also influence our motor behaviours even when interaction with these objects is not required. The visual system might directly detect visual information about the behavioural possibilities afforded to us by objects and surfaces, known as affordances (Gibson,1979), hence supporting the view that perception and action are closely linked.Plants of previous researches focused on affordance, have found these studies show about visuomotor priming effect, also named affordance effect. It has been demonstrated that the appearance of an object automatically activates two different components of the grasping action which are compatible with some of the object’s visual properties such as its location, its size and the orientation of eventual graspable parts. This effect has been attributed to an affordance for action, that is, the perception of an object results in the potentiation of those actions.Recently, few inverse compatibility effect observed that it deserves our prompt action. Loach, Frischen, Bruce and Tsotsos (2008)produced in prime-probe task paradigm show that an attentional mechanism inhibits competing motor programs that could elicit erroneous actions. Such suppressive surround effects are hallmarks of attentional processing in the visual domain, also can observed behaviorally in the motor domain. Compatible responses were faster than incompatible responses if the two handles shared an identical orientation, but they were slower if the two handles were aligned at slightly dissimilar orientations. It is worth noting that, in their experiment the prime and probe object share various degree affordance. Thus, present research is concerned with analyzing the pure effect of suppressive surround in the motor domain.The orientation of prime handle and probe handles in our experiment keep varied as Loach, in our experiment l,we exchanged the action state of two handles, aims to verify the inhibition of motor-based inhibitory annulus is affected by action state. In experiment 2, we exchanged the object to torch, investigate how they influence the motor-based inhibitory annulus.With our experiment 1, The orientation of prime handle and probe handles keep varied as Loach et al. (2008), but we exchanged the action state of two handles. The result do not show center surround inhibition associated with this motor program inhibit other motor programs coding for slightly dissimilar which indicated that the inhibition of motor-based inhibitory annulus is affected by action state. We further control the action state of the two handles in experiment 2 investigate how they influence the motor-based inhibitory annulus. These results suggest that the inhibition effect observed when the prime handle are active object. And further prove that the effect is not affected when the prime handle are passive object. We add experiment 3 measured the inhibition effect using between-and within-hand response sets. The inhibition effect of within-hand condition is significantly smaller than that in within-hand condition. The results provide evidence that the inhibition effect for inhibitory annulus is occur in the motor domain and not to the visual domain.Summing up all the results and discussions, present research conduct following conclusion:(1) In our prime-probe task,the inhibition of motor-based inhibitory annulus is affected by action state.(2) The inhibition effect is modulated by the object action state of prime. If the two handles were aligned at slightly dissimilar orientations. When the prime object in the passive-state, visuomotor priming effect is observed If the two handles were aligned at slightly dissimilar orientations. But the prime object in the object-state, the invert visuomotor priming effect is observed. Means that suppressive of motor domain and visual domain through variety of mechanisms(3) Our research highlights that the inhibition effect for inhibitory annulus is occur in the motor domain and not to the visual domain.
