Effects of extended training (nine sessions, 50 trials each) on two-way avoidance response latencies were studied. For each rat, auditory and visual warning signals (CS) were presented on separate trials, either according to a Gellermann series or in 25-trial blocks. Intermittent presentation of the two kinds of trials yielded shorter latencies and higher levels of avoidance performance in response to the noise CS than in response to the darkness CS. Presentation of trials in blocks revealed stronger response-eliciting properties of stimuli presented during the second half of the session than of those presented during the first half. A significant decrease of avoidance performance in the early portions of the delay period, an index of inhibition of delay, was obtained on auditory trials presented in the second half of the sessions. Results indicate that strong fear of the warning signal is required for inhibition of delay of avoidance responses.  相似文献

Risk behavior was investigated among 1,053 Danish adolescents aged 12–20. Driving a car while intoxicated was rare even among the oldest adolescents, but riding a bicycle while intoxicated was reported by the majority of adolescents aged 14–20. Driving a car at high speeds was widespread among the oldest adolescents (aged 18–20), but still lower than rates reported for same-age American adolescents. Rates of sex without contraception were higher than expected, in spite of early and extensive sex education, while rates of illegal drug use other than marijuana were extremely low. Participation in risk behavior was analyzed in relation to sensation seeking, city size, and various family variables. Results are discussed in the context of the theory of broad and narrow socialization, in which a cultural and multidimensional understanding of socialization is emphasized.  相似文献

In this study we examined the effect of heart rate and behavioral measures of attention on distractibility of 6-, 9-, and 12-month-old infants. The infants were presented with a toy, and a distractor was presented while they attended to the toy. The distractor was presented during heart rate changes indicating sustained attention or attention termination, or during periods of time when behavioral ratings indicated the infant was in focused or casual attention. There were longer distraction latencies during attentional engagement as defined by heart rate changes or behavioral ratings than for periods of inattention. Infants had the longest distraction latencies when heart rate and behavior measures were congruent with respect to attention engagement (heart rate deceleration and focused attention). Conversely, latencies were shortes for congruent values of inattention (heart rate acceleration and casual attention). Infant information processing may be greatest when a heart rate deceleration occurs simultaneously with an episode of focused attention.  相似文献

Large‐scale research projects, conducted in a cross‐European context, are increasingly attractive to educational researchers and policy‐makers. However, this form of comparative research across cultures brings problems concerning the standardization of data collection and analysis, particularly where ethnographic research is concerned, as it prioritizes a full range of qualitative research strategies. This paper outlines the use of a universal model and the approaches recently taken by two research teams and contrasts these with another recent nine‐partner comparative European study that used ethnographic methods. We then describe the analytical procedures used in the project, which encouraged participant observation and individual researcher interpretation in order to generate grounded accounts and outline how they were culturally sensitive and meaningful to research teams who used varied analytical approaches. However, this raised difficult issues for the ‘final’ analysis and the production of a loosely coupled research report. Our pragmatic solution was a process of ‘qualitative synthesis’ whereby individual partner reports were collated by the Project Director and treated as data and a grounded theory approach was applied to generate tentative theory in respect of creative learning. The paper concludes by arguing that data generated by a loosely coupled approach to qualitative comparative research which uses a wide range of data collection methods can be effectively analysed with a qualitative synthesis.  相似文献

The Reconstruction of Primary Teachers' Identities   总被引:3,自引:0,他引:3  
Primary teachers have had to reconstruct their identities in response to the reconstruction of the education system. The holism, humanism and vocationalism of the old Plowden self-identity has been challenged by a new assigned social identity signalled in the assault on child-centred philosophy, the diminution of elementary trust, and changes in the teacher role. These challenges have thrown up new dilemmas for teachers, and represent 'fateful moments' in the careers of their identities. In trying to resolve the dilemmas, teachers have engaged in identity work, characterised mainly by identity talk, and a number of emotional and intellectual strategies. The result has been a partitioning of the old Plowden self-identity, with the 'real self' being largely withheld from the new personal identity and the sense of vocationalism being set to one side. The new personal identity in teaching represents a more instrumental and situational outlook, with the substantial self finding more expression elsewhere. Identity work is still in progress and seems set to continue while teachers have to find ways of relating to two or more competing discourses.  相似文献

Planning and organizing the young child's curriculum and classroom environment is an essential component in the early childhood education program. Every fall in the USA millions of children begin and continue to participate in formal school settings. These children are all unique and differ in cognitive and social maturity.Jeffrey I.

Students may not fully demonstrate their knowledge and skills on accountability tests if there are no stakes attached to individual performance. In that case, assessment results may not accurately reflect student achievement, so the validity of score interpretations and uses suffers. For this study, matched samples of students taking state accountability tests under low-stakes and high-stakes conditions were used to estimate the effect of stakes on test performance and subsequent pass rates. Across five assessments, expected performance was greater under high-stakes conditions, with effect sizes ranging from 0.41 to 0.50 standard deviations and with students of lower ability tending to be slightly more affected by stakes. Depending on where cut scores were set, pass rates differed by up to 30% when comparing the low- and high-stakes conditions.  相似文献

Many educators in the 21st century utilize social media platforms to enrich professional learning networks (PLNs). PLNs are uniquely personalized networks that can support participatory and continuous learning. Social media services can mediate professional engagements with a wide variety of people, spaces and tools that might not otherwise be available. Teachers who once might have had access to only a handful of colleagues can now employ Facebook, Twitter and other mediums to learn from peers across the globe at any time. However, educators face numerous challenges building and enhancing their PLNs for professional growth. To support educators in the development of their PLNs, we present a framework for PLN enrichment. Rooted in our research and experiences with PLNs, this flexible framework is designed to help educators reflect upon how they might continuously improve their PLN experiences and outcomes.  相似文献
