Visual attention selectively enhances the neural response to a task-relevant item. But what happens when an item outside the primary focus of attention is also relevant to the task at hand? In a dual-task fMRI experiment, we studied the responses in retinotopically organized visual cortex in such a situation. Observers performed an attention-demanding task in the fovea while another, unmasked s...

the present study aimed to examine throwing accuracy and spatial and digit working memory of field dependent-independent participants. the group embedded figure test (geft) was distributed among 320 male students and based on the geft scores, 45 participants were randomly divided into field dependent, field independent and control group (15 participants/each group). the study included two tasks...

background several studies showed that dopamine and norepinephrine improve retention and retrieval of memory. methylphenidate is an enhancer of dopamine and norepinephrine in brain. objectives in the present study, the effect of methylphenidate was evaluated on retention and retrieval of memory in young and aged mice using passive avoidance apparatus. materials and methods animals were divided ...

Iconic gesture is a rich source of information for conveying ideas to learners. However, in order to learn from iconic gesture, a learner must be able to interpret its iconic form-a nontrivial task for young children. Our study explores how young children interpret iconic gesture and whether they can use it to infer a previously unknown action. In Study 1, 2- and 3-year-old children were shown ...

This paper describes preliminary research work aimed at obtaining a multi-level iconic representation of 3D objects from geometric meshes. A single-level iconic model describes an object through parts of different dimensions connected to form a hypergraph. The multi-level iconic model, called Non-manifold Multi-Tessellation, incorporates decompositions of an object into parts at different level...

introduction: working memory is thought to serve as a part of memory structure where functions like temporary storage and manipulation of information take place. this study investigates the effectiveness of working memory training regimens with iranian university students, while considering the implications for medical students. methods: thirty university students studying at different universi...

The subject of the review is monograph “Peter I in Media Memory” by Denis S. Artamonov and Sophia V. Tikhonova. Like their previous study on historical memory, scientists rely a variety empirical material, including microformatted Internet content, cinema, animation, video games. One central concepts book, mediatization, explored through its application to legendary figure Peter First. analysis...
