The goal of this study was to determine whether children's true and false witness statements could be differentiated using the model of reality monitoring. The effects of age and verbal ability on scales based on the model were also investigated. Children (N = 68) from three different age-groups (7--8, 10--11, and 13--14 years) made both a true and a false statement concerning a mildly traumatic event. The statements were analysed using the Revised Memory Characteristics Questionnaire. The vocabulary sub-scale of the WISC-R was also administered. True statements were found to contain more sensory information and expressions of time, and less affective information. Overall, 64% of the statements were correctly classified on the basis of the scales. Older children received higher scores on most of the reality monitoring scales compared to the youngest children regardless of the truthfulness of their statements. Furthermore, the verbal ability of the children was positively associated with scores on several of the scales. The classification accuracy suggests that the model should not be applied to individual cases of child testimony. Although the final decision concerning the usefulness of the scales should be based on ecologically valid field studies. 相似文献

本实验系统地考察了在不同刺激率、信号率条件下警觉水平的变化 ,并分析了以往警觉理论的适应条件。实验一采用 5次 /分、1 5次 /分和 30次 /分的刺激率条件 ,发现检测正确率在各条件下随时间的变化是由于 d′下降所致 ,而β值基本不变 ,可以认为警觉随时间下降是由于疲劳所致 ;中等刺激率条件下的 d′最高 ,低刺激率次之 ,高刺激率最差并且高刺激率导致被试唤醒水平降低。实验二在 30次 /分的高刺激率条件下变化信号率 (分别为 3次 /分、6次 /分和 1 2次 /分 ) ,发现信号率变化不会改变 d′,但导致β值的变化 ,可以认为高信噪比导致被试的唤醒水平升高 相似文献

Driver state monitoring (DSM) systems aim to measure driver/occupant state, considering factors such as fatigue, workload, attentiveness, and wellbeing. They are influential for some vehicles on the road today, but as we move towards higher levels of automation their use is expected to become even more important. Uncertainty around public perception of these systems is a potentially limiting factor, with potential concerns for privacy, data storage, perceived utility, and reliability amongst other things posing potential threats. A survey was conducted based on the Universal Theory of Acceptance and Use of Technology (UTAUT) framework, which collected 311 individual responses to explore the acceptability of this technology in specific relation to conditionally and partially automated vehicles. This paper identified that the factors of effort expectancy, performance expectancy, social influence, and attitudes towards using new technology are all positively related to overall behavioural intention, whereas anxiety is negatively related. Other demographic influences are discussed, and recommendations made for future research and marketing/implementation of DSM systems to ensure acceptance by future users. 相似文献

在认知任务中,伴随编码和检索的外围信息被称为上下文,其本身并不是编码或检索的目标。如果学习时的上下文在其后进行提取时重复出现,不管是否对应之前的学习项目,都会增加个体再认正确的概率。这种由于上下文增强项目熟悉感而促进记忆效果的现象就称为上下文熟悉效应。本研究通过两个实验探究上下文熟悉效应对元记忆监测及记忆的影响机制。其中,元记忆监测是以学习判断和信心判断为指标。记忆成绩则是以再认正确率为指标。研究结果显示:第一,上下文熟悉效应影响元记忆监测:学习判断等级上,恢复条件显著高于新条件,且不受任务难度影响; 信心判断等级上,简单任务时恢复条件与新条件无显著差异,困难任务时恢复条件显著高于新条件。第二,上下文熟悉效应影响记忆成绩:再认成绩上,简单任务时新条件显著高于恢复条件; 困难任务时恢复条件显著高于新条件。研究得出结论:上下文熟悉效应对元记忆监测和记忆都有显著影响,任务难度起调节作用。 相似文献

Further research is needed on strategies to improve employment outcomes for individuals with autism spectrum disorder (ASD). We replicated and extended prior research by examining the acquisition, maintenance, and generalization of discrete‐trial training (DTT) performance of adults with ASD who were interested in careers as behavior technicians. Three participants received training on how to implement DTT with children and we assessed the maintenance and generalization of DTT performance in the absence of feedback. Results indicated that procedural integrity generalized across children and targets and maintained for 6 to 17 session days without feedback. Results have implications for the successful employment of individuals with ASD as behavior technicians and for future research on strategies to enhance their performance on the job. 相似文献

The stepping-stone variant of the hidden pathway maze learning (HPML) task paradigm has been extensively used to investigate cognitive functions in neuropsychology and neuropharmacology. Previous studies have used total error across trials, as well as rule-break errors and learning errors, to define spatial memory and/or executive function in healthy and impaired adults and children. However, the construct validity of performance measures on HPML tasks has not been established in healthy children. To assess the construct validity of measures of exploratory and rule-break errors on the Groton Maze Learning Task (GMLT) measures of spatial sequence memory (Corsi Blocks Task) and spatial error monitoring (Continuous Paired Associate Learning; CPAL) were used. The results indicate that Corsi span predicted GMLT spatial sequence memory and CPAL accuracy predicted GMLT spatial error monitoring. The construct validity of the GMLT as a measure of spatial memory and executive function are discussed with regard to prior research using HPML tasks in neuropsychological contexts. 相似文献

Repeated measurements of episodic memory are needed for monitoring amnestic mild cognitive impairment (aMCI) and mild Alzheimer’s disease (AD). Most episodic memory tests may pose a challenge to patients, even when they are in the milder stages of the disease. This cross-sectional study compared floor effects of the Visual Association Test (VAT) and the Rey Auditory Verbal Learning Test (RAVLT) in healthy elderly controls and in patients with aMCI or AD (N = 125). A hierarchical multiple regression analysis was used to examine whether linear or quadratic trends best fitted the data of cognitive test performance across global cognitive impairment. Results showed that VAT total scores decreased linearly across the range of global cognitive impairment, whereas RAVLT total scores showed a quadratic trend, with total scores levelling off for 90% of aMCI patients and 94% of AD patients. We conclude that the VAT shows few if any floor effects in patients with aMCI and mild AD and is therefore a potentially promising cognitive test for monitoring episodic memory impairment. 相似文献

In this research, we combine a cross-form word–picture visual masked priming procedure with an internal phoneme monitoring task to examine repetition priming effects. In this paradigm, participants have to respond to pictures whose names begin with a prespecified target phoneme. This task unambiguously requires retrieving the word-form of the target picture's name and implicitly orients participants' attention towards a phonological level of representation. The experiments were conducted within Spanish, whose highly transparent orthography presumably promotes fast and automatic phonological recoding of subliminal, masked visual word primes. Experiments 1 and 2 show that repetition primes speed up internal phoneme monitoring in the target, compared to primes beginning with a different phoneme from the target, or sharing only their first phoneme with the target. This suggests that repetition primes preactivate the phonological code of the entire target picture's name, hereby speeding up internal monitoring, which is necessarily based on such a code. To further qualify the nature of the phonological code underlying internal phoneme monitoring, a concurrent articulation task was used in Experiment 3. This task did not affect the repetition priming effect. We propose that internal phoneme monitoring is based on an abstract phonological code, prior to its translation into articulation. 相似文献
