OBJECTIVE To test the hypothesis that anosognosia for hemiparesis results from intrahemispheric disconnection. METHODS Using right carotid barbiturate injection as a model for anosognosia for hemiparesis, systematic attempts were made to modify deficit awareness by providing the left hemisphere with explicit information regarding left upper extremity function. RESULTS Experimental intervent...

Although sensorimotor adaptation is typically thought of as an implicit form of learning, it has been shown that participants who gain explicit awareness of the nature of the perturbation during adaptation exhibit more learning than those who do not. With rare exceptions, however, explicit awareness is typically polled at the end of the study. Here, we provided participants with either an expli...

27 Although sensorimotor adaptation is typically thought of as an implicit form of learning, 28 it has been shown that participants who gain explicit awareness of the nature of the perturbation 29 during adaptation exhibit more learning than those that do not. With rare exceptions, however, 30 explicit awareness is typically polled at the end of the study. Here, we provided participants with 31...

Metadiscourse markers help writers make coherent and reader- friendly texts, thus of considerable importance in academic writing. The main aim of this study was to investigate how interactive and interactional metadiscourse markers are used by Iranian EFL learners. An inquiry was carried out to investigate cross-cultural similarities and differences in the use of metadiscourse markers in the Di...

To process complex stimuli like language, our auditory system must tolerate large acoustic variance, like speaker variability, and still be sensitive enough to discriminate between phonemes and to detect complex sound relationships in, e.g., prosodic cues. Our study determined discrimination of speech sounds in input mimicking natural speech variability, and detection of deviations in regular p...

A key feature of human cooperation is that we can coordinate well without communication or negotiation. We achieve this by anticipating the intentions and actions of others, and adapting our own actions to them accordingly. In contrast, most multi-robot systems rely on extensive communication to exchange their intentions. This paper describes the joint approach of our two research groups to ena...

We study a discrete analog of the Lagrange-d’Alembert principle of nonhonolomic mechanics and give conditions for it to define a map and to be reversible. In specific cases it can generate linearly implicit, semi-implicit, or implicit numerical integrators for nonholonomic systems which, in several examples, exhibit superior preservation of the dynamics. We also study discrete nonholonomic syst...

The long history of persuasion research shows how to change explicit, self-reported evaluations through direct appeals. At the same time, research on how to change implicit evaluations has focused almost entirely on techniques of retraining existing evaluations or manipulating contexts. In five studies, we examined whether direct appeals can change implicit evaluations in the same way as they d...
