Contextual control of first- and second-learned excitation and inhibition in equally ambiguous stimuli     

James Byron Nelson 《Learning & behavior》2009,37(1):95-106

In two three-phase experiments, rats received a final third excitatory (Experiment 1) or inhibitory (Experiment 2) phase of conditioning with a tone. The third phase came immediately prior to a test with the tone, either in the context where the tone was trained or in a different context. Groups differed in each experiment with respect to the first two phases. Rats in Groups EIE (Experiment 1) and EII (Experiment 2) received excitatory conditioning with the tone in Phase 1, followed by inhibitory conditioning with the tone. Rats in Groups IEE (Experiment 1) and IEI (Experiment 2) received inhibitory conditioning in Phase 1, followed by excitatory conditioning in Phase 2. Thus, the association being expressed in Phase 3 was consistent either with what was learned first about the stimuli or with what was learned second. Contrary to expectations, the association being expressed at the end of Phase 3, either excitatory or inhibitory, was affected by a context change, regardless of its consistency with what was learned first about the CS.  相似文献   

Developing and designing online engineering ethics instruction for international graduate students     

Katherine A. Austin  Greta J. Gorsuch  William D. Lawson  Byron P. Newberry 《Instructional Science》2011,39(6):975-997

The present project embarked on an educational intervention, consisting of a series of online ethics learning modules, to aid international graduate students in overcoming the acculturation barriers to understanding and inculcating normative ethical obligations associated with engineering practice and research in the United States. A fundamental initial step in the process of helping international, as well as domestic, engineering graduate students embrace ethical obligations is to provide clear instruction on fundamental engineering ethical principles and values relevant in the United States. Most institutes of higher education do not have a cohesive approach to basic graduate engineering ethics instruction, much less materials that have been calibrated for international students (National Science Foundation, , 2009). Herein the authors describe our instructional intervention, as well as to document the development, design, and assessment of the learning modules intended to provide students with a framework for learning ethical precepts and applying them in the engineering field. Think-Aloud Protocol and Cognitive Task Analysis results were used to improve the content modules and learning experience. Initial pilot findings indicate that the content modules increased student knowledge acquisition compared to pre-test performance, indicating a step-forward in the formulation of a useful learning tool for graduate engineering ethics instruction.  相似文献   

Longitudinal Trajectories of Family Functioning Among Recent Immigrant Adolescents and Parents: Links With Adolescent and Parent Cultural Stress,Emotional Well-Being,and Behavioral Health

This study examined longitudinal effects of adolescent and parent cultural stress on adolescent and parent emotional well-being and health behaviors via trajectories of adolescent and parent family functioning. Recent immigrant Latino adolescents (M_age = 14.51) and parents (M_age = 41.09; N = 302) completed measures of these constructs. Latent growth modeling indicated that adolescent and parent family functioning remained stable over time. Early levels of family functioning predicted adolescent and parent outcomes. Baseline adolescent cultural stress predicted lower positive adolescent and parent family functioning. Latent class growth analyses produced a two-class solution for family functioning. Adolescents and parents in the low family functioning class reported low family functioning over time. Adolescents and parents in the high family functioning class experienced increases in family functioning.  相似文献   

Developmental Trajectories of Acculturation: Links With Family Functioning and Mental Health in Recent‐Immigrant Hispanic Adolescents          下载免费PDF全文

The present study was designed to examine acculturative changes, and their effects on mental health and family functioning, in recent‐immigrant Hispanic adolescents. A sample of 302 Hispanic adolescents was assessed five times over a 2½‐year period. Participants completed measures of Hispanic and U.S. practices, collectivist and individualist values, and ethnic and U.S. identity at each time point. Baseline and Time 5 levels of mental health and family functioning were also assessed. Latent class growth analyses produced two‐class solutions for practices, values, and identifications. Adolescents who increased over time in practices and values reported the most adaptive mental health and family functioning. Adolescents who did not change in any acculturation domain reported the least favorable mental health and family functioning.  相似文献

Networks of value in electronic music: SoundCloud,London, and the importance of place     

Daniel Allington  Byron Dueck  Anna Jordanous 《Cultural Trends》2015,24(3):211-222

While recent debate has often focused on a reified “cultural value” (whether opposed to or aligned with monetary value), this article treats “value” as a verb and investigates the acts of valuing in which people engage. Through ethnographic research in London's electronic music scene and social network analysis of the SoundCloud audio sharing website (which is dominated by electronic dance music and, to a lesser extent, hip hop), it uncovers substantial patterns of geographical inequality. London is found at the very centre of a network of valuing relationships, in which New York and Los Angeles occupy the next most privileged locations, followed by Berlin, Paris, and Chicago. Cities outside Western Europe and the Anglophone world tend to occupy peripheral positions in the network. This finding suggests that location plays a major role in the circulation of value, even when we might expect that role to have been curtailed by an ostensibly “placeless” medium for the distribution and valuing of music. While there are reasons for the metropolitan emplacedness of dance music – given the importance of the relationship between production, consumption, and live DJing – the privileging of particular cities also mirrors patterns of inequality in the wider cultural economy. That London should appear so supremely privileged reflects both the exporting strength of British creative industries and the imbalanced nature of the UK's cultural economy.  相似文献   

IT artifact bias: How exogenous predilections influence organizational information system paradigms     

Michael Curry  Byron Marshall  Peter Kawalek 《International Journal of Information Management》2014

Efforts in IS research have long sought to bridge the gap between the information technology (IT) function and strategic business interests. People perceive affordances (possibilities for action) in information technology artifacts differently as cognitive structures (schema) which bias individual focus. This study explores how an individual's tendency to perceive the ‘trees’ in an IT ‘forest’ (artifact preference) affects their assessment of efforts to achieve more effective IT outcomes. The effect is demonstrated using a relatively simple IT success model. Further, in a sample of 120 survey responses supported by ten semi-structured interviews, we demonstrate that job role and organizational IT complexity systematically impact artifact perception. A better understanding of IT artifact bias promises to help organizations better assess information systems.  相似文献
