Rats do show primacy and recency effects in memory for lists of spatial locations: A reply to Gaffan
It has been demonstrated that rats display both primacy and recency effects in list-learning experiments for both item- and order-recognition memory for spatial location information. Contrary to a suggestion made by Gaffan (1992) that previous demonstrations of primacy effects in rats are not valid due to statistical and methodological problems, we show that (1) it is not likely that our results are due to experimenter bias and/or nonindependence of trials, (2) primacy and recency effects are obtained whether or not one uses a training criterion, and (3) when many of the published reports from our laboratory are combined, the number of subjects and trials are sufficient to evaluate the validity of primacy and recency effects in list-learning experiments. 相似文献

Despite the growing interest, Open Innovation (OI) in Intangible Assets (IAs) research is still fragmented and displays a limited contextual focus. This paper aims to provide a clearer view of these issues and represents a first step toward filling such research gap. A systematic literature review and a synthesis of high-quality contributions with a focus on a general overview of research on OI and IAs in OI processes have been carried out. By critically evaluating the current body of literature and definitions, we have moved a step further toward comprehending the multiple facets of existing research and highlight several promising areas for future development. In particular, we have analyzed the role of IAs in OI practices by selecting a synthesis and a critical review of their different exploitations. We have combined multiple algorithms to produce a clear topical taxonomy of the multiple strands of research lying at the interface of OI and IAs. 相似文献

Person reliability parameters (PRPs) model temporary changes in individuals’ attribute level perceptions when responding to self‐report items (higher levels of PRPs represent less fluctuation). PRPs could be useful in measuring careless responding and traitedness. However, it is unclear how well current procedures for estimating PRPs can recover parameter estimates. This study assesses these procedures in terms of mean error (ME), average absolute difference (AAD), and reliability using simulated data with known values. Several prior distributions for PRPs were compared across a number of conditions. Overall, our results revealed little differences between using the χ or lognormal distributions as priors for estimated PRPs. Both distributions produced estimates with reasonable levels of ME; however, the AAD of the estimates was high. AAD did improve slightly as the number of items increased, suggesting that increasing the number of items would ameliorate this problem. Similarly, a larger number of items were necessary to produce reasonable levels of reliability. Based on our results, several conclusions are drawn and implications for future research are discussed. 相似文献

We believe that the ideas associated with the Maker Movement have profound implications for teacher education. We have isolated the pedagogical principles of hack, adapt, design, and create as central to exploring how they work with teacher candidate participants in a maker pedagogy lab. We frame these ideas as Maker Pedagogy, which is the enactment of the principles inspired by the maker movement in the classroom to foster learners who operate as innovators, creators, sharers and givers of knowledge, tools and technologies. The purpose of our self-study research is to describe, interpret and analyze how our pedagogies of teacher education and our critical friendship have changed and developed as a result of providing experiences for teacher candidates in our maker pedagogy lab. In this project we use self-study methodology to investigate our teaching and practices, and we dialogue about our tacit and personal knowledge as it contributes to the knowledge and understanding of our teaching through Maker Pedagogy. In particular, the emphasis is on critical collaborative inquiry through critical friends and on dialogue as a valued component of our research. Of particular interest were data in the video recordings of each lab that indicated that one or both of us had reframed our understanding of maker pedagogy. The findings are framed as three themes that document what we are learning about Maker Pedagogy through teaching teacher candidates. These are (1) the value of self-study methodology, (2) Maker Pedagogy as distinct and (3) deepening our pedagogies of teacher education. 相似文献
