In five experiments, rehearsal and recall phenomena were examined using the free recall and immediate serial recall (ISR)
tasks. In Experiment 1, participants were presented with lists of eight words, were precued or postcued to respond using free
recall or ISR, and rehearsed out loud during presentation. The patterns of rehearsal were similar in all the conditions, and
there was little difference between recall in the precued and postcued conditions. In Experiment 2, both free recall and ISR
were sensitive to word length and presentation rate and showed similar patterns of rehearsal. In Experiment 3, both tasks
were sensitive to word length and articulatory suppression. The word length effects generalized to 6-item (Experiment 4) and
12-item (Experiment 5) lists. These findings suggest that the two tasks are underpinned by highly similar rehearsal and recall
processes. 相似文献

The purpose of this investigation was to assess the reliability and validity of eight developmental asset measures among a stratified, random sample (N = 540) of college students to guide health promotion efforts. The sample was randomly split to produce exploratory and confirmatory samples for factor analysis using principal axis factoring and varimax rotation and structural equation modeling techniques. Items were retained on factors if they had high loadings greater than .40 and were not complex. Concurrent validity was examined among substance use (including alcohol and tobacco) and sexual risk-taking variables. Exploratory and confirmatory samples did not differ on demographics. Parallel analysis confirmed the eight theorized constructs. Exploratory factor loadings were greater than .40. Concurrently, validity analyses were in the predicted direction. Cronbach alphas were .70 or greater with the exception of the Future Aspirations asset. Preliminary analyses support the reliability and validity of measuring developmental assets among emerging adults. Implications and potential uses are discussed. 相似文献

In this paper, we present an integrated ethical framework that covers the different levels of ethical tasks inherent in forensic and correctional work. First, we briefly give an overview of the ethical framework and its component notion of human dignity. Second we analyze in depth the concept of dignity and its relationship to normative theories and ethical concepts that are particularly relevant for forensic practitioners. Third, we explore the capacity of the conceptions of human dignity and vulnerable agency to integrate principles typically contained in ethical codes and practice, such as beneficence, autonomy, and justice. Fourth, we discuss how conflict between ethical codes or duties of station adhered to by practitioners can be effectively addressed in light of the model of dignity and agency outlined earlier. Fifth, we explain how individuals' specific ethical judgments and actions should proceed in light of our framework model. 相似文献

Correctional practitioners work within a context that is heavily influenced and constrained by punishment policies and practices. The overlap between the normative frameworks of punishment and offender rehabilitation creates a unique set of ethical challenges for program developers and therapists. In this paper we set out to briefly outline three major punishment theories and draw out their implications for correctional practitioners. First, we discuss the nature of punishment and the problems it poses for practitioners and all citizens in liberal democracies. Second, consequential, retributive, and communicative justifications of punishment are succinctly described and their clinical implications analyzed and some limitations noted. Finally we conclude with some suggestions for ethical practice in correctional settings. 相似文献

ObjectiveThe objective of the study was to identify and describe the extent, function, nature, and timeline of practice and preparation activities undertaken by experts in order to adapt to constraints unique to a specific upcoming competition.MethodA content analysis was conducted of data from interviews with 15 expert orienteers and six experienced orienteering coaches about competition-specific preparation in the sport of orienteering.ResultsThe analysis revealed several key concepts. First, competition-specific preparation is necessary because the constraints of a given orienteering competition vary across competitions. Second, owing to such variance, orienteers have limited advance information about the specific constraints of an upcoming competition, which impedes their preparation for that competition. Third, expert orienteers engage in a range of activities designed to gather information about the constraints of an upcoming competition. Fourth, this information is then used to identify or create practice environments that represent these constraints. Practice within these environments enables expert orienteers to adapt to these constraints before competing.ConclusionsCompetition-specific preparation appears critical to performance in sports in which environmental constraints change considerably between competitions. 相似文献

We examined the ability of domestic dogs to choose the larger versus smaller quantity of food in two experiments. In experiment 1, we investigated the ability of 29 dogs (results from 18 dogs were used in the data analysis) to discriminate between two quantities of food presented in eight different combinations. Choices were simultaneously presented and visually available at the time of choice. Overall, subjects chose the larger quantity more often than the smaller quantity, but they found numerically close comparisons more difficult. In experiment 2, we tested two dogs from experiment 1 under three conditions. In condition 1, we used similar methods from experiment 1 and tested the dogs multiple times on the eight combinations from experiment 1 plus one additional combination. In conditions 2 and 3, the food was visually unavailable to the subjects at the time of choice, but in condition 2, food choices were viewed simultaneously before being made visually unavailable, and in condition 3, they were viewed successively. In these last two conditions, and especially in condition 3, the dogs had to keep track of quantities mentally in order to choose optimally. Subjects still chose the larger quantity more often than the smaller quantity when the food was not simultaneously visible at the time of choice. Olfactory cues and inadvertent cuing by the experimenter were excluded as mechanisms for choosing larger quantities. The results suggest that, like apes tested on similar tasks, some dogs can form internal representations and make mental comparisons of quantity. 相似文献

In two experiments, we examined the effect of output order in immediate serial recall (ISR). In Experiment 1, three groups of participants saw lists of eight words and wrote down the words in the rows corresponding to their serial positions in an eight-row response grid. One group was precued to respond in forward order, a second group was precued to respond in any order, and a third group was postcued for response order. There were significant effects of output order, but not of cue type. Relative to the forward output order, the free output order led to enhanced recency and diminished primacy, with superior performance for words output early in recall. These results were replicated in Experiment 2 using six-item lists, which further suggests that output order plays an important role in the primacy effect in ISR and that the recency items are most highly accessible at recall. 相似文献
