Spoken production requires lexical selection, guided by the conceptual representation of the to-be-named target. Currently, the question whether lexical selection is subject to competition is hotly debated. In the picture-word interference task, manipulating the visibility of written distractor words provides important insights: clearly visible categorically related distractors cause interferen...
We investigated meta- and paracontrast masking using tasks requiring observers to judge the surface brightness or else the contours of target stimuli. The contour task revealed strongest metacontrast at SOAs shorter than those obtained for the brightness task. Paracontrast revealed related temporal differences between the tasks. Additionally, the paracontrast results support the existence not o...
Responses to pictures of famous tennis and soccer athletes are slower when the responding effector is a hand or foot, respectively, indicating that visual recognition of individuals characterized by skilled motor behavior interferes with the motor reactivity of nonproficient observers. By contrast, directly viewing actions induces motor facilitation, suggesting that actions are mapped in the ob...
Many crowd ideation systems seek to gather scores of ideas from people online. However, this often leads to many bad ideas and duplication. A dedicated facilitator who guides exploration of the solution space is a common and effective strategy for optimizing ideation in face-to-face brainstorming, but has not yet been explored in computer-supported crowd ideation. We introduce IdeaGens, a socia...
Young adult and aged F344 rats were compared on a silent gap variant of the prepulse inhibition paradigm. Animals were tested using a 50-ms single tone cue, followed by 8 days of silent gap testing. The first 3 days of gap testing were long gaps (range 2 to 100 ms) followed by 5 days of short gaps (range 2 to 10 ms). The effects of gap length, prior experience, and age, on the magnitude and dir...
We demonstrate that in the macaque monkey there is robust, short-latency facilitation by ventral premotor cortex (area F5) of motor outputs from primary motor cortex (M1) to contralateral intrinsic hand muscles. Experiments were carried out on two adult macaques under light sedation (ketamine plus medetomidine HCl). Facilitation of hand muscle electromyograms (EMG) was tested using arrays of fi...
Many different functional roles have been ascribed to the motor system due to its prevalent recruitment in perceptual and cognitive tasks other than motor production. We discuss findings that suggest the motor system might take on multiple roles that vary with context and the brain networks involved. Using single-pulse TMS, we measured the corticospinal excitability of the FDI muscle in primary...
Aims: Deep sense plays a significant role in sensory control feedback, joint stability, coordination and balance. Despite the important role of vision and Proprioceptive Neuromuscular Facilitation on functional skills in athletes, a few studies have been conducted in this regard. This study aimed at investigating the effects of Proprioceptive Neuromuscular Facilitation exercises on dynamic visu...
The purpose of this study was to compare performance children with Developmental Coordination Disorder (DCD) and typically developing (TD) in a dual task paradigm dynamic balance on the Wii Fit as primary concurrent cognitive (counting) or bimanual fine motor secondary tasks. Using cross-sectional design, 25 DCD 38 TD were assessed Movement Assessment Battery for Children, 2nd edition (MABC-2) ...
