This article tests the hypothesis that self-development plays a role in the offset of childhood amnesia; assessing the importance of both the capacity to anchor a memory to the self-concept, and the strength of the self-concept as an anchor. This research demonstrates for the first time that the volume of 3- to 6-year old's specific autobiographical memories is predicted by both the volume of their self-knowledge, and their capacity for self-source monitoring within self-referencing paradigms (N = 186). Moreover, there is a bidirectional relation between self and memory, such that autobiographical memory mediates the link between self-source monitoring and self-knowledge. These predictive relations suggest that the self-memory system is active in early childhood. 相似文献

Magnetic-inertial measurement units (MIMUs) are becoming more prevalent in sports biomechanics and may be a viable tool to evaluate kinematic parameters. This study examined the accuracy of a MIMU to estimate orientation angles under static conditions and dynamically from a squash racket during a forehand drive shot. A MIMU was mounted onto a goniometer and moved through 0–90°, with static data collected at 10° increments during 10 repetitions of all three axes. Typical error analyses showed the MIMU to be very reliable (TE ≤ 0.03°). MIMU accuracy was determined via intraclass correlation coefficients (ICC) (r > 0.999, p < 0.001). An ordinary least products regression showed no proportional bias and minimal fixed bias for all axes. Dynamic accuracy was assessed by comparing MIMU and optical motion capture data of squash racket swing kinematics. A MIMU was fixed onto a racket and 10 participants each hit 10 forehand shots. Mean orientation angle error at ball impact was <0.50° and ICC showed very high correlations (r ≥ 0.988, p < 0.001) for all orientations. Swing phase root mean squared errors were ≤2.20°. These results indicate that a MIMU could be used to accurately and reliably estimate selected racket swing kinematics. 相似文献

Traditionally, internships have provided a unique way for criminal justice students to gain work experience while earning academic credit. Questions remain, however, as to whether a student's educational experiences adequately reflect the realities of internship (and other work-related) experiences. As part of a larger study, we sought to explore student views and attitudes regarding their undergraduate curriculum and its relevance to their experiences at the criminal justice agencies. Through the use of self-report surveys, findings were two-fold, indicating tremendous support for internship programs. Moreover, (1) students felt their undergraduate curricula adequately reflected the practical realities of criminal justice operations, and (2) internships were regarded as invaluable in preparing students for criminal justice careers. 相似文献

The purpose of this study was to assess the effect of periodized resistance training on accelerative sprint performance. Sixteen physically active men participated in a randomized controlled study. An experimental group (n = 10) completed an 8-week periodized resistance training intervention, while a control group (n = 6) did not train. Pre- and post-training measures of 20-m straight-line sprint time, including a 10-m split, maximum strength, and explosive strength, were recorded. Flight time, stance time, stride length, and stride frequency were quantified from digitized video recordings of the first three strides of the 20-m sprint. Resistance training resulted in significant increases in maximum strength (parallel back squat: 19%) and explosive strength (6–10%). However, both groups increased 0–10 m sprint times (experimental group = 6%; control group = 3%) while 10–20 m times were reduced (experimental group = 7%; control group = 4%), highlighting the mechanical differences between the distinct sprint phases. The change during the 0–10 m interval was accompanied by a reduction in stride frequency during the first three strides. Strength coaches should be aware that the potential benefits of increased muscular strength during short sprints are likely to be affected by mechanical specificity and that improvements in sprinting performance may not occur immediately after a period of resistance training. 相似文献

Three experiments showed a savings procedure to be an effective and sensitive alternative to sensory preconditioning procedures as a measure of associations among neutral stimuli. Experiment 1 showed that within-compound associations developed more rapidly in reinforced appetitive serial compound conditioning when nonreinforced preexposure to the serial compound was given than when separate element or no preexposure was given. Experiment 2 showed the savings effect to be highly stimulus specific. Experiment 3 examined the facilitation of serial compound conditioning after either simultaneous or serial nonreinforced preexposure to the elements of the compound. The results of that experiment were consistent with those of analogous sensory preconditioning experiments. When preexposure involved only the two elements of the subsequently reinforced compound, serial preexposure produced more savings than simultaneous preexposure. But when preexposure involved a three-stimulus procedure like that used by Rescorla (1980b), simultaneous preexposure resulted in more savings. Advantages of the savings procedure over sensory preconditioning as a measure of association among neutral stimuli are discussed. 相似文献

The Disabilities Information Flow (DIF) project at the University of St Andrews has sought to provide a means of efficiently managing all student disabilities information within the institution and provide appropriate role‐based service interfaces for all staff who need to routinely interact with this information. This paper describes the software engineering processes used for the context analysis, design and implementation of the DIF. 相似文献

The similarity of process in psychotherapy and in the interpersonal dynamics of tertiary teaching is of interest in attempting to maximise student interest and success. This article reviews the similarities in predictors of positive outcome in both psychotherapy and tertiary education, and suggests that the two processes have a great deal in common. This suggestion is tested by comparing the personality variables (as measured by the Adjective Check List) which predict success in two dissimilar medical courses, Physical Chemistry and Counselling Skills. Results indicate that, in both courses, variables which predict success include aspects of personal adjustment and intellectual style which also would predict success in psychotherapy. It is concluded that the interaction of personal and interpersonal factors in success in tertiary courses may be based on similar processes as success in psychotherapy, and that these processes warrant further research. 相似文献
