Document Summary
Where system: location of objects and guiding our responses, occipital-parietal pathway. Feature detection: visual processing is so highly effective due to two key characteristics: functional specialization: cells are specialized in function. Cells are specialized in their receptive fields. Receptive field: portion of the visual field that the cell responds to. Firing rate decreases when the stimulus is entirely on the surround: parallel processing: many different types of analyses happen at the same time. Spatial position: location is the same, put two and two together. Neural synchrony: neurons start to fire together. Attention: if overloaded, conjunction errors can occur. Perceptual constancy: when the sensory information we receive changes, the properties of the object appear constant: to achieve this, we use unconscious inference. Perceived size= perceived distance x size of retinal image. If retinal image doubles, the perceived distance gets cut in half. Depth perception: oculomotor cues: only effective at short viewing distances.
