Many written English words contain silent letters. Omitting them produces nonwords pronounced identically to the original words, for example, SALM for PSALM and COLUM for COLUMN. We report two naming and two lexical decision experiments in which targets of 4–11 letters followed primes exposed for 100 ms in mask-prime-mask-target sequences. Priming in SALM-psalm and COLUM-column pairs exceeded priming in orthographic control pairs such as ASTA-pasta and COUSI-cousin, pairs in which pronounced letters are omitted to form the primes. SALM and COLUM, however, were less effective primes than PSALM and COLUMN. Results were discussed in terms of the phonological coherence hypothesis, the role of orthographic codes in filtering phonologically activated representations, and graphemes as reading units. 相似文献

In the study phase of these experiments, subjects were asked to think of an item suggested by the omission in an incomplete sentence, and then look at a picture or word describing an item and say whether it was the same as theirs. In the test phase, they were asked to identify studied and nonstudied items presented briefly in either picture or word form. Subjects were then required to recall the words or pictures shown in the study phase. Experiment 1, with a within-subjects design, revealed that the studied pictures were identified more readily than studied words and nonstudied pictures. This indicates a physical priming effect. In word identification, studied words were identified more readily than nonstudied words; however, there was no difference between studied words and studied pictures, and the performance for studied pictures and nonstudied items were largely the same. The physical priming effect on picture identification was also shown in Experiment 2, with a between-subjects design. Different processing mechanisms in picture and word identification are discussed. 相似文献

Over the first year and a half of life, the duration of memory becomes progressively longer, the specificity of the cues required for recognition progressively decreases after short test delays, and the latency of priming progressively decreases to the adult level. The memory dissociations of very young infants on recognition and priming tasks, which presumably tap different memory systems, are also identical to those of adults. These parallels suggest that both memory systems are present very early in development instead of emerging hierarchically over the 1st year, as previously thought. Finally, even young infants can remember an event over the entire "infantile amnesia" period if they are periodically exposed to appropriate nonverbal reminders. In short, the same fundamental mechanisms appear to underlie memory processing in infants and adults. 相似文献

遗忘症患者外显与内隐记忆实验研究:语义性启动效应任务 总被引:4,自引:1,他引:3
采用WMS—CR和MMSE对临床脑损伤患者进行了认知功能与记忆功能两方面的筛选,获得9名遗忘症患者。然后采用偏好和自由联想两项语义性启动效应任务进行测验,发现遗忘症患者在外显记忆受损情况下,的确存在语义性启动效应,且与正常对照相近。推论语义性启动效应任务与遗忘患者损伤的颞叶或间脑结构无关。同时还讨论了启动效应任务,认为偏好任务采用言语性材料不是理想的方法。 相似文献

The present study deals with the question of whether judgments made by experts working in familiar contexts are affected by prior expectations and beliefs. Two experiments in which prior expectations were manipulated were designed to determine whether and to what extent polygraph examiners are affected by their prior expectations when analyzing and interpreting polygraph charts. Prior expectations affected the examiners' judgments when the polygraph charts did not include clear indications of guilt or innocence, but when the objective physiological evidence included strong indications which clearly contradicted the examiner's expectations, judgments were not affected by these expectations. Theoretical and practical implications of these results are discussed. 相似文献

The purpose of this study was to (1) examine the direct association of parent-, coach-, and peer-initiated motivational climate with high school athlete burnout and engagement and (2) evaluate whether peer-initiated motivational climate mediates or moderates the association of coach-initiated motivational climate with burnout and engagement. Athletes (n = 150) completed a survey on their perceptions of parent-, coach-, and peer-initiated motivational climate, burnout, and engagement. Findings supported the mediation model, but not the moderation model. In addition to mastery and performance climate direct effects, significant medium-to-large indirect pathways from coach mastery climate → peer mastery climate → burnout, β = -.15, 95% CI [-.333, −.009], and coach mastery climate → peer mastery climate → engagement, β = .19, 95% CI [.020, .293] were observed. Findings support that a parent, coach, and peer-initiated mastery motivational climate was associated with burnout and engagement while a performance climate was mostly unrelated to these indices of athlete well-being. In addition to direct associations with burnout and engagement, coaches also had an indirect association through peer mastery-initiated motivational climate. Findings advance understanding of how parents, coaches, and peers conjointly shape athlete burnout and engagement. 相似文献

This study investigated the idea that when one recalls past episodes, that the content of those memories will activate additional episodic memories with like content, and such memories will then have the potential of surfacing in subsequent acts of involuntary and voluntary recall. We tested the episodic content priming hypothesis in two experiments. In Experiment 1, priming group participants first recalled memories about specific activities or events and then they were subsequently engaged in a word-cue voluntary autobiographical memory task. The results showed that priming group participants produced more episodic memories involving the primed content on this task than control participants occupied in the same task. In Experiment 2, episodic content priming was further tested on a measure of involuntary autobiographical memory (i.e., the vigilance task). The results on this task also revealed support for the episodic content priming hypothesis, including after a delay of 24 h. 相似文献

ObjectivesSelf-efficacy is one of the most reliable correlates of physical activity, yet a growing body of literature has demonstrated that traditional self-efficacy measures may be flawed because they measure perceived capability and other constructs such as motivation. This study adds to this evidence base by comparing a standard self-efficacy measurement group and two measurement conditions that may provide greater validity: motivation held constant (i.e., adding “If you really wanted to” at the beginning of the item) and vignette (i.e., adding a clarifying vignette before the item). The first objective of this study was to compare these groups regarding self-efficacy scores. The second objective was to examine whether physical activity level (i.e., adhering to physical activity guidelines or not) interacted with measurement condition.DesignRandomized cross-sectional design with three independent groups.MethodParticipants were 444 undergraduate students (M age in years = 21.10, SD = 3.73) who completed an online survey measuring physical activity self-efficacy and behaviour.ResultsThe vignette group had higher self-efficacy scores than the standard and motivation held constant groups. Scores were also higher among those adhering to guidelines and there were no differences between the groups for physically active individuals. Finally, among those not adhering to the guidelines, the vignette group had especially high scores compared to the other groups.ConclusionsThis study demonstrated that reading a vignette prior to completing a self-efficacy item clarifies the meaning of the item thereby improving validity of the measure. 相似文献
