Rats were trained to locate food in a response, direction, or place problem on an open field located at 2 positions. In Experiment 1, both the response and direction groups solved the problem. The place group failed to solve the task in approximately 300 trials. Experiment 2 demonstrated that rats need distinguishable start points to solve a place problem when neither a response nor a direction solution is available. Findings from Experiment 3 suggest that a combination of path traveled and distinct cues help to differentiate start points. Experiment 4 replicated the findings using a T maze. These results suggest "place" solutions are difficult for rats. The data are discussed with respect to conditional learning and modern spatial mapping theory. 相似文献

The authors provide a useful historical link between the civil rights movement in the 1960s and the disability rights movement. The origins of the Civil Rights Act of 1964, the Americans with Disabilities Act (ADA), and the Rehabilitation Act of 1973 are discussed from the sociopolitical context at the time of their passage. Important links are drawn between these laws, affirmative action, cultural diversity, and multiculturalism. The authors address the role of the counselor with respect to becoming advocates for persons with disabilities in the face of injustice. 相似文献

In three experiments with 56 3-month-olds, we examined the effect of different numbers of reinstatements (reminders) on long-term retention. Infants learned to move a crib mobile by kicking and subsequently received one, two, or three reinstatements. Each reinstatement was a partial training episode one-sixth the duration of original training. Presenting a single reinstatement when the memory was inactive failed to recover it 1 day later (Experiment 1), but increasing the number of reinstatements when the memory was active to two (Experiment 2) and three (Experiment 3) progressively protracted retention. Although 3-month-olds typically remember for less than 6 days, after three reinstatements they still exhibited retention 6 weeks after training. Untrained controls who received an identical regimen of reinstatements exhibited no retention. These results demonstrate that periodic reinstatements can maintain young infants' retention over long delays and that the state of the memory at the time of reinstatement is critical to its effectiveness. 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

In this study, we used a four-step social validation process to identify and validate critical skill components that constitute high school students' conversational behavior. The four steps were nominating target behaviors, establishing a normative range of performance, manipulating simulations of behavioral dimensions, and comparing ratings of judges to levels of performance on those behavioral dimensions. Multiple measures, both quantitative and qualitative, suggested that the rate and percentage of time initiating and responding verbally, the percentage of time attending, and the percentage of time not engaging in distracting motor behavior related to favorable ratings by a wide variety of 60 judges. Findings are discussed in relation to the utility of the multistep social validation process and the identification of critical social skill components as targets of interventions. 相似文献

Recently, much attention has focused on declining levels of civic engagement as a symptom of a wide range of social ills. Some claim that Americans' tendency to endorse individualistic beliefs to the exclusion of a collective or societal interest value accounts for declining levels of civic engagement. This study investigated whether a value commitment to benefit the collective, called societal interest, helps to explain civic engagement. Data from the 1990–1992 National Election Studies panel study were used to evaluate whether a societal interest value helps to explain participation in community affairs and efforts to solve collective problems. The findings support the hypothesis that societal interest influences the likelihood of engaging in behavior to benefit the collective. These findings support the view that human behavior is influenced by multiple motives (including a desire to benefit the collective). Expressions of commitment to societal interest are more than mere lip service to noble ideals; they have real consequences for behavior. 相似文献

Binocular Rivalry Disrupts Visual Priming 总被引:1,自引:0,他引:1
Many results implicate perceptual processing in repetition priming, but little is known of potential mechanisms for priming. A new method was used to help determine the processing stage at which priming occurs. Priming pictures were presented under dominance or suppression generated by binocular rivalry. Although low-level, sensory attributes can be processed under rivalry suppression, there is no evidence that repetition priming can be supported by such low-level processing. Priming was found only for stimuli that were processed sufficiently to be identified in the priming stage. The results demonstrate that repetition priming requires processing of stimulus attributes into relatively high-level representations. 相似文献

Memory Processing of a Serial List By Young Infants 总被引:1,自引:0,他引:1
Michelle Gulya Carolyn Rovee-Collier Lissa Galluccio & Amy Wilk 《Psychological science》1998,9(4):303-307
Serial list learning is thought to be beyond the capabilities of infants before the end of their 1st year. In separate experiments with 3- and 6-month-olds, we studied infants' memory for a serial list using a modified serial probe recognition procedure that was originally developed for monkeys and a precuing procedure that was previously used with human adults. Infants were trained with a three-item list. One day later, they were precued with one list member and tested for recognition of another. When the precue specified valid order information, infants of both ages recognized the test item; when the precue specified invalid order information, infants of neither age did. These findings reveal that even very young infants can learn and remember the order of items on a serial list. 相似文献
