A laboratory experiment examines the claims that (1) humans are susceptible to flattery from computers and (2) the effects of flattery from computers are the same as the effects of flattery from humans. In a cooperative task with a computer, subjects (N"41) received one of three types of feedback from a computer: ‘‘sincere praise’’, ‘‘flattery’’ (insincere praise) or ‘‘generic feedback’’. Compa...

Communication of emotions is of crucial importance in music performance. Yet research has suggested that this skill is neglected in music education. This article presents and evaluates a computer program that automatically analyzes music performances and provides feedback to musicians in order to enhance their communication of emotions. Thirty-six semi-professional jazz /rock guitar players wer...

This paper explores the feasibility of using EEG in the context of Stimulus Rich Reactive Interfaces (SRRI’s), as a source of feedback on the cognitive state of the user. We have run experiments to evaluate the utility of two potential EEG measures of whether a stimulus has been perceived: 1) reduced EEG power in the alpha band at posterior brain areas and 2) a P3-like positive deflection over ...

A major concern in computer music performance is the lack of intimacy between one’s haptic senses and the sound being produced. Through the use of computer-controlled force and vibrational feedback, a closer relationship between a performer and sound production may be formed. The development of a haptic interface for computer music will allow for the study of relationships between the haptic se...

IN THE PAST FEW DECADES, COMPUTER-ASSISTED LANGUAGE Instruction (CALI), or Computer-Assisted Language Learning (CALL), has been of interest because of its potential for providing individualized instruction. Interactivity between the computer and the learner is one of the important elements in CALI. Compared to a traditional textbook or workbook, a CALI program can provide immediate feedback on ...

To be correctly mastered, brain-computer interfaces (BCIs) need an uninterrupted flow of feedback to the user. This feedback is usually delivered through the visual channel. Our aim was to explore the benefits of vibrotactile feedback during users' training and control of EEG-based BCI applications. A protocol for delivering vibrotactile feedback, including specific hardware and software arrang...

corrective feedback (cf) and its different types have long absorbed many scholars and practitioners. as ellis (2009) mentioned some experimental studies need to be carefully designed to discover the relative effectiveness of each of these cf techniques. the goal of this qualitative study was to discover whether the employment of different cf strategies could bring about an attitudinal shift. to...

BACKGROUND The objective of this study was to evaluate the implementation of a 'virtual' (computer-mediated) approach to health research commissioning. This had been introduced experimentally in a DOH programme--the 'Health of Londoners Programme'--in order to assess whether is could enhance the accessibility, transparency and effectiveness of commissioning health research. The study described ...
