Observational learning of a successive discrimination problem by pigeons was studied using conspecifics as models responding for either contingent or noncontingent reinforcement. We found that observation of these models was associated with poorer performance on subsequent testing than was shown by a control group that learned without first observing conspecifics' performance. No significant difference was found between subjects without observational experience and another control group that was confined in the observation apparatus and observed an empty chamber only.  相似文献

Neurolinguistic and psycholinguistic studies suggest that grammatical (gender) and phonological information are retrieved independently and that gender can be accessed before phonological information. This study investigated the relative time courses of gender and phonological encoding using topographic evoked potentials mapping methods. Event-related brain potentials (ERPs) were recorded using a high resolution electroencephalogram (EEG) system (128 channels) during gender and phoneme monitoring in silent picture naming. Behavioural results showed similar reaction times (RT) between gender and word onset (first phoneme) monitoring, and longer RT when monitoring the second syllable onset. Temporal segmentation analysis (defining dominant map topographies using cluster analysis) revealed no timing difference between gender monitoring and word onset monitoring: both effects fall within the same time window at about 270–290 ms after picture presentation. Monitoring a second syllable onset generated a later effect at about 480 ms. Direct comparison between gender and first phoneme monitoring revealed a difference of only 10 ms between tasks at approximately 200 ms. Taken together, these results suggest that lemma retrieval and phonological encoding may proceed in parallel or overlap. Word onset is retrieved simultaneously with gender, while the longer RT and the later ERP effect for second syllable onset reflect that segmental encoding continues incrementally to the following phonemes.  相似文献

The construct of career adaptability, or the ability to successfully manage one's career development and challenges, predicts several important outcomes; however, little is known about the mechanisms contributing to its positive effects. The present study investigated the impact of career adaptability on job satisfaction and work stress, as mediated by individuals' affective states. Using a representative sample of 1671 individuals employed in Switzerland we hypothesized that, over time, career adaptability amplifies job satisfaction and attenuates work stress, through higher positive affect and lower negative affect, respectively. The data resulted from the first three waves of a longitudinal project on professional paths conducted in Switzerland. For each wave, participants completed a survey. Results of the 3-wave cross-lagged longitudinal model show that employees with higher career adaptability at Time 1 indeed experienced at Time 3 higher job satisfaction and lower work stress than those with lower career adaptability. The effect of career adaptability on job satisfaction and work stress was accounted for by negative affect: Individuals higher on career adaptability experienced less negative affect, which led to lower levels of stress and higher levels of job satisfaction, beyond previous levels of job satisfaction and work stress. Overall results support the conception of career adaptability as a self-regulatory resource that may promote a virtuous cycle in which individuals' evaluations of their resources to cope with the environment (i.e., career adaptability) shape their affective states, which in turn influence the evaluations of their job.  相似文献

There is an abundance of literature on serial homicide from a Western perspective that outlines operational definitions, types of offenders and how they prey upon their victims. However, currently, there is a lack of studies that compare serial homicide in different countries. The current study aims to give an overview of the demographics of serial homicide offenders and victims in South Africa and compare these to the demographics of offenders and victims from other currently available empirical studies of other countries. The sample consisted of 33 out of the total 54 solved series in South Africa between 1936–2007, which includes a total of 33 offenders, 302 victims, and 254 crime scenes. Results of the sample as a whole showed that South African serial homicide offenders are similar to offenders in other countries in terms of their actions at the crime scene and victim choice, with some notable exceptions. Additional analysis looked at the offender's consistency of targeting certain types of victims across their homicide series in comparison with the patterns of serial homicide offenders in other countries.

Abstract

The primary purpose of this study was to identify 10 leading former Soviet Union sport psychologists and describe their major contributions. The investigators also desired to determine the status and future directions of sport psychology in Russia and the other new countries that formerly comprised the Soviet Union. Balloting for the leading sport psychologists occurred at the newly formed meeting of the Interstates Association of Sport Psychologists (IASP) and 10 persons were identified: Anatoli V. Alekseev, Marina V. Ennolaeva, Leonid D. Gissen. Gennadij D. Gorbunov, Nickolai A. Hudadov. Piotr A. Jorov. Juri A. Kolomeitzev, Albert V. Rodionov, Vladimir R. Sopov, and Bronislav A. Viatkin. These individuals were subsequently interviewed and the results indicated that although many cutbacks have occurred during the previous decade (1980–1990). sport psychologists continue their work. They are developing new and innovative ways to help athletes improve their individual and collective performance. Their work in psychodiagnostics is exemplary. Nevertheless, the future of sport psychology remains uncertain in the Former Soviet Union.  相似文献

In his work on Iberian Jews—openly practicing ones and conversos, on and off the peninsula, before 1492 and 1497 and after—Yosef Hayim Yerushalmi made few explicit methodological statements. But from his earliest work, he made his historiosophical commitments clear and rarely wavered from them. Those commitments included basic trust in inquisitorial sources, the investigation of both marginal and normative Jewish practices, interest in the history of mentalities, and, above all, a focus on the relationship between “immanent” and external causes in Jewish history. This article traces the influence of several mid-twentieth-century historians on Yerushalmi’s work and examines his place in twentieth-century debates on conversos and the Inquisition; it also discusses his relationship to microhistory and the problem of historical distance and perspective. The article concludes by considering the apparent contradiction between Yerushalmi’s emphasis on the agency and subjectivity of Jews and his trust in the records of an institution that some have characterized as pervasively anti-Jewish.  相似文献

A large body of autism research over the last 20 years has shown that people with autism have difficulties understanding mental states. This has been conceived of as a metarepresentational deficit. An open question is whether people with autism's metarepresentational deficit is limited to the mental domain. This research explores individuals with autism's understanding of the representational nature of pictures. With the use of ambiguous figures, where a single stimulus is capable of representing two distinct referents, we compared metarepresentational abilities in the pictorial and mental domains and the perception of pictorial ambiguity. Our findings indicate that individuals with autism are impaired in mental metarepresentation but not in pictorial metarepresentation. These findings suggest that children with autism understand the representational nature of pictures. We conclude that children with autism's understanding of the representational nature of pictures is in advance of their metarepresentational understanding of mind. Their perception of figure ambiguity is comparable to the typical population.  相似文献
