This experiment examined contextual interference in producing a bimanual coordination pattern of 90 degree angle relative phase. Acquisition, retention, and transfer performance were compared in a single-task control group and groups that performed 2 tasks in either a blocked or random presentation. Surprisingly, acquisition data revealed that both the random and control groups outperformed the...

In the two sections of this article, I examine aspects of the analysis and reporting of interaction in focus groups. In both sections, I argue that the essential importance of interaction for producing the data in focus groups does not correspond to any requirement that the analysis or the reporting of that data should emphasize interaction. With regard to analyzing interaction, the goals of th...

In the present study, we examined whether perceptual learning methods can be used to improve performance of older individuals. Subjects performed a texture discrimination task in the peripheral visual field and a letter discrimination task in central vision. The SOA threshold was derived by presenting a mask following the stimuli. Older subjects (age greater than 65 years) were either trained f...

Although online focus groups are emerging as a worthwhile methodological approach for qualitative researchers, reporting has been constrained in several ways. The majority of studies report asynchronous groups, whereas others employ synchronous exchanges, the efficacy of which with young people has seldom been explored. Considering the popularity of the Internet as a communication tool for youn...

This paper describes the use of focus groups as a data-gathering tool, in both theoretical and practical terms. Calder's discussion of focus groups is presented as the basis of the theory, and the marketing study conducted by the Midcontinental Region of the National Network of Libraries of Medicine serves as the backdrop to highlight some of the practical aspects of using this qualitative data...

Although consumer opportunistic behavior has drawn attention from managers and scholars for a long time, a special context of two-sided market has been ignored. A multi-stage research program, comprising in depth interviews (Study 1) and three experimental studies (Studies 2, 3, 4), explored opportunistic claiming during service guarantee. The main characteristics of two-sided market (consumer,...
