The dynamics of categorization: Unraveling rapid categorization.
We explore a puzzle of visual object categorization: Under normal viewing conditions, you spot something as a dog fastest, but at a glance, you spot it faster as an animal. During speeded category verification, a classic basic-level advantage is commonly observed (Rosch, Mervis, Gray, Johnson, & Boyes-Braem, 1976), with categorization as a dog faster than as an animal (superordinate) or Golden ...

متن کاملUltra-Rapid Scene Categorization with a Wave of Spikes
Recent experimental work has shown that the primate visual system can analyze complex natural scenes in only 100-150 ms. Such data, when combined with anatomical and physiological knowledge, seriously constrains current models of visual processing. In particular, it suggests that a lot of processing can be achieved using a single feed-forward pass through the visual system, and that each proces...
متن کاملUltra Rapid Object Categorization: Effects of Level, Animacy and Context
It is widely agreed that in object categorization bottom-up and top-down influences interact. How top-down processes affect categorization has been primarily investigated in isolation, with only one higher level process at a time being manipulated. Here, we investigate the combination of different top-down influences (by varying the level of category, the animacy and the background of the objec...
متن کاملUltra-Rapid Categorization of Meaningful Real-Life Scenes in Adults With and Without ASD.
In comparison to typically developing (TD) individuals, people with autism spectrum disorder (ASD) appear to be worse in the fast extraction of the global meaning of a situation or picture. Ultra-rapid categorization [paradigm developed by Thorpe et al. (Nature 381:520-522, 1996)] involves such global information processing. We therefore tested a group of adults with and without ASD, without in...
