Multimedia is being used increasingly to provide computer based instruction. One reason for this trend may be the assumption that multimedia information helps people learn. To find out whether there is empirical support for this assumption, this paper reviews studies from a wide variety of fields to show that multimedia -may be able to help people learn more information more quickly compared to...

This field study investigated the effect of retaking identical selection tests on subsequent test scores of 4,726 candidates for law enforcement positions. For both cognitive ability and oral communication ability selection tests, candidates produced significant score increases between the 1st and 2nd and the 2nd and 3rd test administrations. Furthermore, the repeat testing relationships with p...

Previous research on basic information-processing tasks has suggested that there may be a dissociation between the underlying process determinants of task performance and associations with ability measures. This study investigates this dissociation in the context of a complex skill-learning task-an air traffic control simulation called TRACON. A battery of spatial, numerical, and perceptual spe...

An experimental treatment was carried out in a sample of 117 preschool children by applying kinesiologic activities. The treatment lasting for 60 minutes was applied for a period of 9 months, twice a week. Control group of 139 children were trained according to the program for preschool institutions. Treatment effects were assessed by 7 motor ability tests, one intellectual test (Raven's Colore...

This work attempts to shed light on the “information technology productivity paradox”. Employing a large data set of Italian manufacturing firms we compute ICT marginal productivity across different cluster of firms and the impact of information and communication technology (ICT) on output growth. Following Yorukoglu’s (1998) vintage capital idea, in which ICT is associated with consistent lear...
