Document Summary

Types of agnosia: appreceptive agnosia, known as visual space agnosia, a condition in which a person has a failure of object recognition caused by impartment in the occipital-temporal vision areas, associative agnosia, known as visual object agnosia. A condition in which a person cannot recognize visually presented objects despite having intact visual perception. Recognizing objects: patients with associative agnosia see but cannot link this input to visual knowledge, they can draw well from memory, this differs from apperceptive agnosia, a perception-based impairment. Intact elementary visual perception, enough to redraw an object an suggestively recognize it. Object recognition: object recognition, object recognition is one central purpose of perception. Is it useful: how can it be utilized, the identification of objects is important for selecting and performing proper actions. Recognition: some early considerations: the process of object recognition is complex, variations in stimulus input , contextual influences, bottom-up processing, top-down processing, data-driven, or stimulus-driven, effects, concept-driven, or knowledge-driven, effects.
