|---|---|---|
| object alternation task | task | No definition submitted yet. |
| object categorization | concept | is when a classifier can learn to automatically categorize objects of the world from a given images, in future images. |
| object centered representation | concept | In an object-centered representation, the position of the subparts of an object are encoded with respect to a set of axes and an origin centered on the object. Several physiological and neuropsychological results support the existence of such representations in humans and monkeys... |
| object detection | concept | deals with detecting instances of semantic objects of a certain class (such as humans, buildings, cars, etc.). |
| object identification | concept | No definition submitted yet |
| object manipulation | concept | is a form of dexterity play or performance in which one or more artists physically interact with props such as balls, hoops, rings, poi, staff, devil sticks, or clubs. Object manipulation can be considered an advanced combinatorial form of sports, dance, and games. |
| object n-back | task | An n-back task in which the stimuli are images of visual objects. |
| object naming task | task | |
| object one-back task | task | A one-back task in which the stimuli are images of visual objects |
| object orientation | concept | No definition submitted yet |
| object perception | concept | The process of transforming basic visual sensory input (such as contrast, edge, motion, color etc) into a more abstract and semantically identifiable whole. |
| object recognition | concept | is the ability to perceive an object’s physical properties (such as shape, colour and texture) and apply semantic attributes to the object, which includes the understanding of its use, previous experience with the object and how it relates to others... |
| object working memory task | task | |
| object-discrimination task | task | Participants are shown pairs or sets of objects. Experimenters then try to discern whether the participant is able to discriminate between the objects. This can be done by having subjects match identical objects to each other, having certain objects become associated with rewards and measuring accuracy, or measuring time spent observing novel objects compared to time spent observing previously seen objects. |
| oculomotor delayed response | task | a task that requires an eye movement to be made to a cued location after a delay |
| odd-even task | task | |
| oddball task | task | A task in which stimuli are presented in a continuous stream and participants must detect the presence of an oddball stimulus. The oddball is a stimulus that occurs infrequently relative to all other stimuli, and has distinct characteristics (e... |
| olfaction | concept | the sense of smell; the act or process of smelling. |
| Olfactory Monitor/Discrimination | task | Subjects are presented with odors and are instructed to smell them passively or to discriminate according to some feature (pleasant/unpleasant, strong/weak, same/different, etc.). |
| olfactory perception | concept | the sensation that results when olfactory receptors in the nose are stimulated by particular chemicals in gaseous form. |
| operation span task | task | A task in which subjects are asked to perform a simple mathematical verification (e.g., 4/2 +1 = 3) and then read a word, with a recall test following some number of those verify/read pairs. The maximum number of words that can be recalled is the "operation span". |
| Orthographic Discrimination | task | Subjects view letters and discriminate according to some feature (uppercase/lowercase, alphabetic order, same/different spelling of words, vowel/consonant, font size, etc.). |
| orthographic lexicon | concept | No definition submitted yet |
| orthographic task | task | A task that requires processing of letter structure |
| orthography | concept | the art of writing words with the proper letters according to standard usage; the representation of the sounds of a language by written or printed symbols; a part of language study that deals with letters and spelling... |
