2439545983 | Attention | The process of focusing on some objects while ignoring others. Can enhance the processing of the attended object. | 0 | |
2439546543 | Attentional Capture | Occurs when stimulus salience causes an involuntary shift of attention. | 1 | |
2439547657 | Autism | A serious developmental disorder in which one of the major symptoms is the withdrawal of contact from other people. | 2 | |
2439547979 | Balint's Syndrome | A condition resulting from damage to a person's parietal lobe. One characteristic of this syndrome is an inability to focus attention on individual objects. | 3 | |
2439548319 | Binding | The process by which features such as color, form, motion, and location are combined to create our perception of a coherent object. | 4 | |
2439549383 | Binding Problem | The problem of how neural activity in many separated areas in the brain is combined to create a perception of a coherent object. | 5 | |
2439550228 | Change Blindness | Difficulty in detecting differences between two visual stimuli that are presented one after another, often with a short blank stimulus interposed between them. Also occurs when part of a stimulus is changed very slowly. | 6 | |
2439550560 | Conjunctional Search | A visual search task in which it is necessary to search for a combination (or conjunction) of two or more features on the same stimulus to find the target. | 7 | |
2439551584 | Dishabituation | An increase in looking time that occurs when a stimulus is changed. | 8 | |
2439552190 | Dual-Task Procedure | An experimental procedure in which subjects are required to carry out simultaneously a central task that demands attention and a peripheral task that involves making a decision about the contents of a scene. | 9 | |
2439553260 | Feature Integration Theory | A theory proposed by Treisman to explain how an object is broken down into features and how these features are recombined to result in a perception of the object. | 10 | |
2439554376 | Feature Search | A visual search task in which a person can find a target by searching for only one feature. | 11 | |
2439554645 | Fixation | The brief pause of the eye that occurs between eye movements as a person scans a scene. | 12 | |
2439555102 | Focused Attention Stage | The stage of processing in feature integration theory in which the features are combined | 13 | |
2439555653 | Habtituation | Paying less attention to the same stimulus that is presented repeatedly. For example, infants look at a stimulus less and less on each successive trial. | 14 | |
2439556137 | High-Load Task | Task that involves more processing resources and that therefore uses more of a person's perceptual capacity. | 15 | |
2439556897 | Illusory Conjunction | Illusory combination of features that are perceived when stimuli containing a number of features are presented briefly and under conditions in which focused attention is difficult. For example, presenting a red square and a blue triangle could potentially create the perception of a red triangle. | 16 | |
2439557353 | Inattentional Blindness | A situation in which a stimulus that is not attended is not perceived, even though the person is looking directly at it. | 17 | |
2439558600 | Load Theory of Attention | Lavie's proposal that the amount of perceptual capacity that remains as a person is carrying out a task determines how well the person can avoid being distracted by task-irrelevant stimuli. If a person's perceptual load is close to perceptual capacity, the person is less likely to be distracted by task-irrelevant stimuli. | 18 | |
2439558898 | Low-Load Task | A task that uses only a small amount of the person's perceptual capacity. | 19 | |
2439559532 | Perceptual Capacity | The resources a person has for carrying out perceptual tasks. | 20 | |
2439560098 | Perceptual Completion | The perception of an object as extending behind occluding objects. | 21 | |
2439560419 | Perceptual Load | The amount of a person's perceptual capacity needed to carry out a particular perceptual task. | 22 | |
2439562995 | Preattentive Stage | An automatic and rapid stage of processing, proposed by Treisman's feature integration theory, during which a stimulus is decomposed into individual features. | 23 | |
2439563407 | Precueing | A procedure in which a cue stimulus is presented to direct an observer's attention to a specific location where a test stimulus is likely to be presented. This procedure was used by Posner to show that attention enhances the processing of a stimulus presented at the cued location. | 24 | |
2439564057 | Saliency Map | A "map" of a visual display that takes into account characteristics of the display such as color, contrast, and orientation that are associated with capturing attention. | 25 | |
2439564748 | Same-Object Advantage | The faster responding that occurs when enhancement spreads within an object. Faster reaction times occur when a target is located within the object that is receiving the subject's attention, even if the subject is looking at another place within the object. | 26 | |
2439565151 | Scene Schema | An observer's knowledge about what is contained in typical scenes. An observer's attention is affected by knowledge of what is usually found in the scene. | 27 | |
2439565531 | Scene Statistics | The probability of various things occurring in the environment. | 28 | |
2439566572 | Spatial Attention | Attention to a specific location. | 29 | |
2439567179 | Stimulus Salience | Characteristics such as bright colors, high contrast, and highly visible orientations that cause stimuli to stand out and therefore attract attention. | 30 | |
2439567508 | Task-Irrelevant Stimuli | Stimuli that do not provide information relevant to the task at hand. | 31 | |
2439568087 | Visual Scanning | Moving the eyes to focus attention on different locations on objects or in scenes. | 32 | |
2439570590 | Covert Attention | Attention without looking. Seeing something out of the corner of your eye, for example | 33 | |
2439571353 | Overt Attention | Attention that involves looking directly at the attended object. | 34 | |
2439572541 | Saccadic Eye Movement | Rapid Eye movement between fixations that occurs when scanning a scene. | 35 |
