Questionnaires concerning attitudes toward use of microcomputers at home, in school, and at video arcades were administered to 879 high school students. Direct observations of adolescent proxemics and sex differences, and of various parameters of video games in 18 video arcades were made. A thorough and representative content analysis of sex bias of microcomputer software advertising brochures was carried out. Results supported previous findings of overrepresentation of masculine culture in the adolescent world of microcomputers, particularly regarding video games. Various types of computer-related activity were not related to socioeconomic class of the parents or to academic grades except for use of home microcomputers, which was mildly positively related to socioeconomic class (r = .124, p less than .001). Nearly half the activity in the arcades was strictly solitary. None of the arcade video games allowed for cooperative play. Most allowed only for sequential competition (86%) or simultaneous competition (7%); as many as 7% did not provide a display of the scores for a second player.  相似文献

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

Facial examiners make visual comparisons of face images to establish the identities of persons in police investigations. This study utilised eye-tracking and an individual differences approach to investigate whether these experts exhibit specialist viewing behaviours during identification, by comparing facial examiners with forensic fingerprint analysts and untrained novices across three tasks. These comprised of face matching under unlimited (Experiment 1) and time-restricted viewing (Experiment 2), and with a feature-comparison protocol derived from examiner casework procedures (Experiment 3). Facial examiners exhibited individual differences in facial comparison accuracy and did not consistently outperform fingerprint analysts and novices. Their behaviour was also marked by similarities to the comparison groups in terms of how faces were viewed, as evidenced from eye movements, and how faces were perceived, based on the made feature judgements and identification decisions. These findings further understanding of how facial comparisons are performed and clarify the nature of examiner expertise.  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

Using a novel approach, in this work, we establish an association between self-reported compliance with COVID-19 preventive behaviors and fear of the virus with morbidity rates (i.e., actual tests and their outcome). In two nationally representative samples that were collected in Israel during the first (April 2020: N = 507) and second (August 2020: N = 515) waves of the COVID-19 pandemic, participants responded to items assessing their compliance with the COVID-19 preventive behaviors and their fear of contracting the virus. Participants' compliance and fear self-reports served as a proxy for morbidity rates. Specifically, we assessed the association between sociodemographic variables (gender, age, or belonging to a minority group), self-reports, and morbidity rates (as reported in publicly open databases of the Israeli health ministry). We found that self-reports of compliance and fear were mirrored and aligned with actual morbidity rates across sociodemographic variables and studies. By establishing a clear connection between specific behavior (i.e., compliance with covid regulations) and emotion (i.e., fear of getting infected by the virus), self-reports and sociodemographic variables represent a real related phenomena (i.e., covid 19 morbidity rates), our findings overall validate numerous studies that used self-reports to assess compliance with COVID-19 preventive behaviors.  相似文献
