A mechanism for generating circadian rhythms has been of major interest in recent years. After the discovery of per and tim, a model with a simple feedback loop involving per and tim has been proposed. However, it is recognized that the simple feedback model cannot account for phenotypes generated by various mutants. A recent report by Glossop, Lyons & Hardin [Science286, 766 (1999)] on Drosoph...

this study investigated criteria and themes required for constructing an objective and communicative psycho-motor mechanism scale based on the theory of translation proposed by pacte. qualitative para- digm was employed in relation to the translation tasks and the number of participants (no.11). feedback through semi-structured interview was obtained to find the descriptors in designing the psy...

This research examines two different kinds of feedback-mechanism to scaffold problem solving as well as interaction in an asynchronous PBL course. An automated feedback mechanism has been used to enhance interaction and group well-being during computer supported collaborative learning. We tracked individual contribution behavior as well as learners’ motivation during collaborative problemsolvin...

With the increasing popularity of touch screen mobile devices, improving the usability and the user experience while inputting text on these devices is becoming increasingly important. Most conventional touch screen keyboards on mobile devices rely heavily on visual feedback, while auditory feedback seldom includes any useful information about what is being inputted by the user. The auditory fe...

Consecutive repetition of actions is common in behavioral sequences. Although integration of sensory feedback with internal motor programs is important for sequence generation, if and how feedback contributes to repetitive actions is poorly understood. Here we study how auditory feedback contributes to generating repetitive syllable sequences in songbirds. We propose that auditory signals provi...

this study aimed at investigating the effect of learners’ gender on their preferences for corrective feedback. learners’ prefer- ences which were investigated included the necessity, frequency, timing, type, method, and delivering agent of error treatment. to this end, a questionnaire was administered to a random sample of 100 participants (50 males and 50 females) studying english (efl) at shi...
