 Attended Intermediate Representation. Another cognitive theory is Jesse Prinz's (2012) Attended Intermediate level Representation theory (AIR).  The theory is a neuro-cognitive hybrid account of conscious. According to AIR theory, a conscious perception must meet both cognitive and neural conditions. It must be a representation of a perceptually intermediate property which Prinz argues are the only properties of which we are aware in conscious experience—we experience only basic features of external objects such as colors, shapes, tones, and feels.  According to Prinz, our awareness of higher level properties—such as being a pine tree or my car keys—is wholly a matter of judging and not of conscious experience.  Hence the Intermediate Representational (IR) aspect of AIR.  To be conscious such a represented content must also be Attended (the A aspect of AIR). Prinz proposes a particular neural substrate for each component. He identifies the intermediate level representations with gamma (40–80hz) vector activity in sensory cortex and the attentional component with synchronized oscillations that can incorporate that gamma vector activity.
