Effects of new types of reinforcement, alien type and alien combined with external type (double reinforcement), were examined in comparison with a conventional external one. One hundred and twenty children, 6th grade boys and girls, worked on learning discrimination tasks. Under alien reinforcement, upon correct responses of the child the experimenter received reinforcers from him-(or her-) self thus reinforcing the child responses. Under each condition, alien, external or double, children learned the tasks and their learning efficacy increased. Personality characteristics of children, in terms of extraversion and emotionality, differentiated effects of three reinforcement conditions on learning behavior and efficacy. The effect of alien reinforcement was influenced by the personality factors most, and that of double reinforcement least. In addition, personality factors influenced differently between alien and external conditions. Learning occurred differently under three different conditions of reinforcement, depending on the personality type of learners. Underlying mechanisms of alien reinforcement were different from, and its functions were independent of, those of external reinforcement. None of the effects of alien reinforcement on learning and motivation were contaminated by the intellectual faculties of learners. 相似文献

COVID-19 vaccine concerns remain high among Americans. Although recent studies have investigated the sociodemographic disparities in vaccine concerns, less attention has been given to reasons for vaccine skepticism and psychosocial factors that may explain it. The current study examined specific types of vaccine concerns among a diverse sample of college students (N = 1985) living in New York City. Participants who identified as Black, younger, with later immigrant generational status, and those with more conservative political leanings reported more vaccine concerns. Concerns regarding vaccine side effects were the most frequently reported source of concern. Reason for getting vaccinated, personal experiences with COVID, and COVID stress was also associated with vaccine concerns. Study results emphasize the importance of sociodemographic factors and COVID knowledge and stress in examining and addressing vaccine concerns. 相似文献

A review of the literature suggests that a paucity of information exists regarding how culture-specific issues such as being both Black and gifted influence the psychological needs and personality development of gifted Black students. Stellar attempts, however, are currently underway to develop theories and perspectives of racial identity development among Black students. These theories and perspectives are discussed in an attempt to understand and address the psychological and social needs of gifted Black students. 相似文献
