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...

The literature on repetition processing reveals an intriguing paradox between the particular salience of repetitions, which makes them easy to learn, and a tendency to avoid them when generating sequences. The aim of this experiment was to study the extent to which children can learn to produce these avoided behaviours by means of an artificial grammar paradigm using generation tests with impli...

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,...

A salt metathesis reaction is a chemical process involving the exchange of bonds between two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. Hyperstructure theory is studied from the theoretical point of view and for its applications. In this paper, we provide some examples of hyperstructures associated with salt m...

, 'N0W' in the early minutes of June 25, the flagraising ceremony proceeds, the vast crowd cheering as Samora Machel, briefly but eloquently, proclaims the country's independence. We're together, representatives of various western support groups, and we embrace one another enthusiastically. Embrace, too, Mozambicans, strangers and old friends. I greet Janet Mondlane, wife of Eduardo, FRELIMO's ...
