there is no doubt that augmented feedback has an important role in improvinglearning. however, it is the content of the feedback which is challenging. the aimof the present study was to examine the effect of feedback on successful versusunsuccessful trials on simple and complex tracking tasks. for this purpose, 48undergraduate right-handed male and female students of hakim sabzevari teachertrai...

Background: The aims of the research that formed the basis of the current study are as follows: Determining methods that are used by teachers for giving feedback in clinical settings. Determining types of feedback, teachers give to their students in clinical settings. Determining barriers of giving feedback and its important teachers’ experience in clinical settings. Methods: This applied res...

At NTCIR-6 CLIR, Toshiba participated in the Monolingual and Bilingual IR tasks covering three topic languages (Japanese, English and Chinese) and one document language (Japanese). For Stage 1 (which is the usual ad hoc task using the new NTCIR6 topics), we submitted two DESCRIPTION runs and two TITLE runs for each topic language. Our first search strategy is Selective Sampling with Memory Rese...

The visual features of an object are processed by multiple, functionally specialized areas of cerebral cortex. When several objects are seen simultaneously, what mechanism preserves the association of features that belong to a single item? We address this question—known as the ‘‘binding problem’’—by examining combinatorial feature selectivity of neurons in area V2. In recording from anesthetize...

While exploring objects, rats make multiple contacts using their whiskers, thereby generating complex patterns of sensory information. The cerebral structures that process this information in the somatosensory system show discrete patterns of anatomically distinct units, each corresponding to one whisker. Moreover, the feedforward and feedback connections are remarkably topographic, with little...

BACKGROUND Like human speech, birdsong is a learned behavior that supports species and individual recognition. Norepinephrine is a catecholamine suspected to play a role in song learning. The goal of this study was to investigate the role of norepinephrine in bird's own song selectivity, a property thought to be important for auditory feedback processes required for song learning and maintenanc...
