Individual differences in cognitive synthesis: An M-capacity analysis

Individual differences in children's propensity to demonstrate cognitive synthesis were evaluated using an artificial reading task. Six-year-olds were asked to demonstrate the meaning of various sentences constructed of logographs, or whole-word symbols, which were arranged in either a meaningful (i.e., grammatical) or scrambled (i.e., ungrammatical) order. Some children demonstrated the sentences in a synthesized mode (expressing a single idea unit), while others used a nonsynthesized mode (expressing the meanings of individual logographs). Overall, synthesizers had a larger attentional reserve, or M-capacity, than nonsynthesizers. The two groups did not differ significantly in age, intellectual level, or reading achievement. As predicted by their larger M-capacity, synthesizers demonstrated from memory significantly more items from meaningful sentences than nonsynthesizers. However, when synthesizers attempted to integrate the scrambled sentences, the excessive operative schemes needed to reorganize the items reduced their recall performance to the level of nonsynthesizers.     

Automatic conceptual encoding of printed verbal material: Assessment of population differences

The release from proactive interference task was used to investigate categorical encoding of animal and clothing items with fourth grade low-socioeconomic status black and middle-socioeconomic status white children. The print mode of verbal presentation and an ordered recall requirement were used in order to provide hospitable conditions for the detection of population differences. The results indicated parity in buildup and release from proactive interference for the two populations. The results of this study, consistent with previous estimates of release from proactive interference for these groups (e.g., D. W. Kee & L. Helfend, Journal of Educational Psychology, 1977, 69, 344–348; S. Y. Nakayama & D. W. Kee, Journal of Educational Psychology, 1980, 72, 386–393), indicate that low-socioeconomic status black and middle-socioeconomic white children do not differ in automatic conceptual encoding. Conceptual encoding differences, however, have been detected between these populations when the free recall method has been used. Thus, discussion of the present results includes a consideration of factors which may be responsible for population differences in free recall performance and preliminary evidence on this issue is provided.     

A game for learning history on mobile devices

This paper presents a game designed to support teaching and learning of Portuguese History to 6th grade students. Firstly, a state of the art of mobile game-based learning for History is presented. Then we describe shortly the research carried out which aimed at the analysis of the games most played by students, followed by the identification of the learning principles proposed by Paul Gee and the game mechanics to propose a game structure. Data was collected from students in the 2nd cycle of the Portuguese Educational System (n = 508) through a questionnaire. Finally, we describe the game, that was developed based on those findings, related to a Portuguese historical event - the Republic Implementation in 1910.

The concentration of commercial success in popular music: An analysis of the distribution of gold records

This paper examines whether commercial success in the popular recorded-music industry, as measured by gold-record output, conforms to an empirical concentration. We find that Lotka's Law overestimates the number of artists with one gold record and underestimates the number of multiplegold-record performing artists. However, for all measures of successful records, theGeneralized Lotka's Law provides an excellent fit, which suggests that the number of performers producingn gold records in about 1/n ^c of those producing one gold record.
