Document Summary
Cross-modal perception is a way of integrating the senses coming from. Chapter 7: the spatial brain regions of space: space is not a single continuous entity, there are different levels of abstraction, spatial attention filters information. Attention tends to coincide with eye fixation due to visual acuity: inattentional blindness, change blindness, inhibition of return: a slowing of reaction time associated with going back to a previously attended location. Right hemisphere thought to be more involved in visual processing: over-attention to left side of space pseuodoneglect. Visual search facilitated by endogenous orienting: allows certain objects to pop out feature integration theory (fit): perceptual features such as colour and shape are coded in parallel and prior to attention. Directs attentional spotlight and guides it from one object to the. Illusory conjunctions support the conclusion that attention needs to be deployed to combine features of the same object correctly. Features tend to be defined post hoc, not a priori.
