Survival of the partial reinforcement extinction effect after contextual shifts

The effects of contextual shifts on the partial reinforcement extinction effect (PREE) were studied in autoshaping with rats. Experiment 1 established that the two contexts used subsequently were easily discriminable and equally salient. In Experiment 2, independent groups of rats received acquisition training under partial reinforcement (PRF) or continuous reinforcement (CRF). Significant PREEs were observed whether extinction occurred in the same or in a different context. In Experiment 3, after PRF or CRF acquisition training, each group received extinction of the same conditioned stimulus in both the same and different contexts. PREEs were observed under both conditions, although extinction was accelerated after a contextual shift. These results were discussed in relation to the role of mediational states in the PREE.     

Time and order effects on causal learning

Five experiments were conducted to explore trial order and retention interval effects upon causal predictive judgments. Experiment 1 found that participants show a strong effect of trial order when a stimulus was sequentially paired with two different outcomes compared to a condition where both outcomes were presented intermixed. Experiment 2 found that a 48-h retention interval eliminates the trial order effect, so that participants gave a global judgment about the relationship between the stimulus and the two outcomes equivalent to the one given by participants that received the two phases intermixed. This result was replicated in Experiment 3 in a situation in which the probability of the outcome in the presence of the cue was changed from .5 for both outcomes (Experiments 1, 2, 4, and 5) to .75 and .25 for outcomes 1 and 2, respectively. Experiment 4 found that retention intervals ranging from 45 min to 48 h eliminated the trial order effect similarly. Experiment 5 found that a 10-min retention interval replicated the effect of time upon sequential training found in precedent experiments, regardless of whether participants remained within the laboratory during the retention interval or spent it outside. The combined results of this experimental series suggest that retention intervals reduce retroactive interference in causal learning by allowing participants to use all the information presented across phases, rather than differentially increasing or decreasing retrieval of information about each of them.     

Effects of test sequence on anterograde and retrograde impairment of negative emotional scenes1

Abstract: The present study examined recognition for sequences of scenes depicting emotional compared with neutral events. In two experiments, participants were presented with a thematic series of 18 slides of scenes in which the content of two critical scenes in the middle of the series were either emotional (dead men's bodies) or neutral (an opera). A two‐item, forced‐choice recognition paradigm was used to test participants’ immediate memory performance of all 18 slides of scenes. In Experiment 1, anterograde and retrograde amnesic effects were observed for the emotional, but not the neutral scenes when a test sequence of scenes was used that did not match the original presentation order. In contrast, in Experiment 2 the test sequence matched the order seen during the original presentation, and both the anterograde and retrograde amnesic effects were not found. These results indicate that the reinstatement of the original event context is an important factor for the recognition of negative emotional memories.     

从我国现行法律看安乐死的实施

安乐死作为自然人在特殊情况下对自己生命自主选择的权利,涉及人的生命权益,有关生命权立法是安乐死问题的关键.安乐死的实施与我国现行法律对生命权的严格维护产生冲突,需要我国用法律的形式肯定安乐死,并对现行法律做出适当调整,为安乐死立法留下法律空间.     

Is A Purely First Person Account Of Human Action Defensible?

There are two perspectives available from which to understand an agent's intention in acting. The first is the perspective of the acting agent: what did she take to be her end, and the means necessary to achieve that end? The other is a third person perspective that is attentive to causal or conceptual relations: was some causal outcome of the agent's action sufficiently close, or so conceptually related, to what the agent did that it should be considered part of her intention? Recent goods based views in ethics are divided as to whether only the first person perspective, or a mix of both perspectives, are necessary to understand intention and action. But resolution of the issue is necessary if goods based views are to be able to deploy to principle of double effect; for that principle requires an account of how to distinguish what is genuinely a matter of intention in human action from what is not. I argue that the pure first person account is better than the mixed account.     

“Everybody knows it’s true”: Social dominance orientation and right-wing authoritarianism moderate false consensus for stereotypic beliefs

European American university students (N = 89) judged the percentage of African Americans who possess 16 traits (e.g., poor, violent, and emotionally expressive) and then estimated how other students would make the same judgments. Participants also completed measures of social dominance orientation (SDO) and right-wing authoritarianism (RWA). Individuals with both high SDO and high RWA held the least positive views of African Americans. False consensus emerged in the form of a significant positive average within-person partial correlation between participants’ own ratings and their judgments of how other students would respond, controlling for the actual responses of other students. False consensus was positively related to SDO and a significant SDO × RWA interaction indicated that false consensus was highest for participants with both high SDO and high RWA. Results suggest that hierarchy-legitimizing beliefs in the form of stereotypes may be sustained internally through false consensus, especially among those most prone to prejudice.     

妊娠期肝内胆汁淤积症研究中的因果论

妊娠期肝内胆汁淤积症是一种常见的妊娠晚期并发症,对围产儿的危害极大,其确切的病因及发病机制尚未十分清楚。只有了解了疾病的起因,才能更好地进行防治。凡病必有其因,以果推因,再取因治果,这是典型的因果论的应用。     

熟悉与陌生品牌启动效应的实验研究

本研究应用任务分离法对熟悉品牌和陌生品牌启动效应年龄特征进行研究,结果发现大学生被试外显成绩高于内隐成绩,且两者有显著差异。进而再采用二次比较法同样以大学生为被试,对熟悉品牌启动效应进行实验,结果表明:(1)学习前带符号组与不带符号组的成绩之间都有极其显著的差异,学习后带符号组与不带符号组之间也有极其显著差异;带符号与不带符号的两组学习前后的成绩均有极其显著的差异;在二次比较法的应用过程中我们发现:(2)如果学习前后的被试为同一组,则会产生“学习污染”。以陌生品牌为材料,用二次比较法在老、青、少三组被进行实验,并将三个年龄段的被试随机分成两组:学习前组(A)和学习后组(B),结果显示:(3)陌生品牌中存在着启动效应,不同年龄段的消费者外显记忆有差异,但内隐记忆没有差异。     

内隐学习在第二语言语音学习中的作用

本研究以大学生为被试,用符合德语读音规则的人造无意义单词(含4~5个音素)为刺激材料,采用强分离程序———匹配和编辑,并增设时间变量,比较了在先匹配后编辑,先编辑后匹配,只匹配,只编辑4种不同内隐、外显学习方式下被试对语音规则的掌握。结果表明,语音学习中存在内隐学习的优势效应,内隐与外显结合的学习方式最好。此外,实验证实了语音的内隐学习也存在长时效应。
