Subitizing but not estimation of numerosity requires attentional resources.
The numerosity of small numbers of objects, up to about four, can be rapidly appraised without error, a phenomenon known as subitizing. Larger numbers can either be counted, accurately but slowly, or estimated, rapidly but with errors. There has been some debate as to whether subitizing uses the same or different mechanisms than those of higher numerical ranges and whether it requires attention...
متن کاملEfficient grasping requires attentional resources
We investigated the effects of visuo-spatial attention on the kinematics of grasping movements by employing a dual-task paradigm. Participants had to grasp cylindrical objects of different sizes (motor task) while simultaneously identifying a target digit presented at a different spatial location within a rapid serial visual presentation (perceptual task). The grasping kinematics in this dual-t...
متن کاملSubitizing requires attention
While counting objects is typically a slow, serial process, enumerating about four or fewer objects has been considered to be a relatively effortless, parallel, and even preattentive process often referred to as subitizing. However, by combining a subitizing task with an attentional blink task, we show that subitizing is systematically affected by a closely preceding letter identification task....
متن کاملTraining attentional control in older adults.
Recent research has demonstrated benefits for older adults from training attentional control using a variable priority strategy, but the construct validity of the training task and the degree to which benefits of training transfer to other contexts are unclear. The goal of this study was to characterize baseline performance on the training task in a sample of 105 healthy older adults and to tes...
متن کاملOlder adults' associative deficit in episodic memory: assessing the role of decline in attentional resources.
In this study, we evaluated an associative deficit hypothesis. This hypothesis suggests that the deficit seen in the episodic memory performance of older adults is due, in considerable part, to older adults' difficulty in binding together unrelated components of an episode into a cohesive entity (Naveh-Benjamin, 2000). The study extended the conditions under which older adults show a differenti...
