The learning of an association between a CS and a US can be retarded by unreinforced presentations of the CS alone (termed latent inhibition or LI) or by un-correlated presentations of the CS and US (termed learned irrelevance or LIRR). In rabbit eyeblink conditioning, there have been some recent failures to replicate LI. LIRR has been hypothesized as producing a stronger retardation effect than LI based on both empirical studies and computational models. In the work presented here, we examined the relative strength of LI and LIRR in eyeblink conditioning in rabbits and humans. In both species, a number of preexposure trials sufficient to produce LIRR failed to produce LI (Experiments 1 & 3). Doubling the number of CS pre-exposures did produce LI in rabbits (Experiment 2), but not in humans (Experiment 4). LI was demonstrated in humans only after manipulations including an increased inter-trial interval or ITI (Experiment 5). Overall, it appears that LIRR is a more easily producible pre-exposure retardation effect than LI for eyeblink conditioning in both rabbits and humans. Several theoretical mechanisms for LI including the conditioned attention theory, stimulus compression, novelty, and the switching theory are discussed as possible explanations for the differences between LIRR and LI. Overall, future work involving testing the neural substrates of pre-exposure effects may benefit from the use of LIRR rather than LI. 相似文献

马克思与虚无主义问题 总被引:1,自引:0,他引:1
马克思的目的是要说明人对价值的需要无须超越历史就能得到满足。认为善(good)内在于历史上与断言善是与历史相同的并非一回事。马克思并不是一个历史主义者——如罗森所使用的术语——因为他没有把善与"所发生之事"等同起来。罗森认为,马克思必定主张在历史中发生的任何事情都是可允许的。马克思的标准是人,而不是历史中在马克思的特定意义上算作人类的(行动)的所有行动。实际上在历史进程中,绝大多数个体是以一种非人的方式把自己对象化的。这就是马克思把前共产主义时期描述为"前历史"的原因,因为那是这样一段时间,在其中社会存在是人类活动的无意识的产物。只有当诸个体自觉地决定其生活并把物质世界置于合作性控制之下,恰当意义上的历史才真正开始。 相似文献

This paper describes a relationship between the variance-covariance matrix of test items and Woodbury's concept of the standard length of a test. An index of item-test relationship is described in standard length terms. The sum of these indices for the items in a test is equal to the square of Jackson's coefficient of sensitivity. 相似文献

The present experiment investigated the impact of the Control Question Test (CQT) and the Guilty Knowledge Test (GKT) on the verdicts of mock jurors. Although studies have indicated that polygraph evidence has little influence on jurors' verdicts (Cavoukian & Heselgrave, 1980; Spanos, Myers, Dubreuil, & Pawlak, 1992–1993), no research has previously distinguished between the different types of polygraph tests and their impact on juror verdicts. In the present study, jurors were shown a videotape of a simulated rape-murder trial that contained either CQT polygraph evidence, GKT polygraph evidence, or no polygraph evidence. No differences were found among the 3 conditions for either jury verdicts or individual juror verdicts, and jurors tended to rate both forms of polygraph testimony below other forms of equally suspect evidence, such as eyewitness testimony, in its influence on their decision-making process. 相似文献

This study examined the relationship between college students' (107 men, 123 women) state motivation and their instructors' perceived use of 10 verbally aggressive messages, e.g., attacks on competence, character, background, and physical appearance; malediction, teasing, ridicule, threats, swearing, or nonverbal symbols. Significant negative correlations were obtained between students' state motivation and instructors' use of seven verbally aggressive messages: attacks on competence, character, or background, malediction, ridicule, threats, and nonverbal symbols. These findings suggest that these types of verbally aggressive messages are related to students' state motivation whereas attacks on physical appearance, teasing, and swearing by the instructor are not related to students' state motivation. 相似文献

The funds, friends, and faith of happy people 总被引:33,自引:0,他引:33

New studies are revealing predictors of subjective well-being, often assessed as self-reported happiness and life satisfaction. Worldwide, most people report being at least moderately happy, regardless of age and gender. As part of their scientific pursuit of happiness, researchers have examined possible associations between happiness and (a) economic growth and personal income, (b) close relationships, and (c) religious faith. 相似文献

The Academic and Behavioral Competencies (ABC) Program, a schoolwide program to reduce classroom disruption and encourage rule following, academic task completion, and homework completion, is described. The program was initially developed and implemented in an elementary school with a high-risk population. Data from teachers, parents, and children indicate high levels of satisfaction with the program. In addition, unobtrusive measures of program impact, reported as reductions in referrals to the principal's office, suspensions, and increases in homework completion rates relative to the year prior to implementation of the program, suggest a preliminary positive impact of the program. A replication is reported for another school district, with teacher evaluations of satisfaction and effectiveness reported, supporting the flexibility and adaptability of the program. Although the present article does not constitute a systematic evaluation of the ABC Program, it presents preliminary data on the process of implementation and stakeholder satisfaction. 相似文献

ProtoMatch is a software tool for integrating and analyzing fixed-location and movement eye gaze and cursor data. It provides
a comprehensive collection of protocol analysis tools that support sequential data analyses for eye fixations and scanpaths
as well as for cursor “fixations” (dwells at one location) and “cursorpaths” (movements between locations). ProtoMatch is
modularized software that integrates both eye gaze and cursor protocols into a unified stream of data and provides an assortment
of filters and analyses. ProtoMatch subsumes basic analyses (i.e., fixation duration, number of fixations, etc.) and introduces
a method of objectively computing the similarity between scanpaths or cursorpaths using sequence alignment. The combination
of filters, basic analyses, and sequence alignment in ProtoMatch provides researchers with a versatile system for performing
both confirmatory and exploratory sequential data analyses (Sanderson & Fisher, 1994). 相似文献

The number, amplitude, duration, and bout structure of isolation-induced ultrasonic vocalization (USV) of infant rats (Rattus norvegicus) were measured on postnatal Day 10. Measurements were made before and after a brief, 1-min, active interaction with their mother or before and after a "pick-up" control procedure. Consistent with prior studies, the number of USVs emitted was significantly increased in the period following the maternal reunion but not after the control procedure. The average amplitude of USVs was also greater following maternal reunion. Finally, analyses characterizing the bout structure of USV production indicated that the average bout size (i.e. number of USVs/bout) was increased severalfold following the reunion with the mother, accounting for the greater rate of USV production during the second isolation period. 相似文献
