We analyze the impact of exercising sports during childhood and adolescence on educational attainment. The theoretical framework is based on models of allocation of time and educational productivity. Using the rich information from the German Socio-Economic Panel (GSOEP), we apply generalized ordered probit models to estimate the effect of participation in sport activities on secondary school degrees and professional degrees. Even after controlling for important variables and selection into sport, we find strong evidence that the effect of sport on educational attainment is statistically significant and positive. 相似文献

In three experiments, rats received pairings of flavor conditioned stimuli with polycose unconditioned stimuli, in either
a simultaneous or a sequential relation. Both temporal relations produced excellent conditioned increases in consumption of
the flavors. Separate presentation of the flavors resulted in extinction in both cases. However, restoring the pairing of
the flavor with polycose resulted in reconditioning only with the sequential, not with the simultaneous, relation. 相似文献

Tape recordings were made of six white and six black ninth-grade northern boys speaking identically worded answers to typical school questions. Black students were given significantly higher grades than white students by 56 white and 50 black southern teachers. Black teachers gave significantly higher grades than white teachers, but no significant interaction was found between students' and teachers' ethnic group. The study is a partial replication of a previous study in which it was found that black students were given significantly lower grades than white students by northern white teachers. 相似文献
