E. Husserl’s reflections in Logical Investigations on “intentional feelings” and “non-intentional feelings” are significant in both his later ethical explorations and M. Scheler’s thought on ethics. Through the incorporation of the views of Husserl and Scheler, we find that the phenomenology of the intentional feeling-acts is not only the foundation of the non-formal ethics of values in Scheler’s phenomenology, but also at least the constitutive foundation of the ethics of Husserl’s first orientation.

特质推理一直是社会认知研究的重要主题,它包括有意图的特质推理和自发特质推理。随着社会认知神经科学蓬勃发展,研究者开始探讨二者的神经机制。fMRI研究表明,特质推理期间主要大脑活动定位于mPFC和TPJ这两个广泛脑区,有意图和自发特质推理分别更多地激活mPFC与TPJ。ERP研究发现,P300是特质推理期间与不一致信息探测和解决过程相关的EEG成分,有意图和自发特质推理在时间进程上大多同步,却激活了不同脑区。总之,当前已积累了较多可信的脑成像证据,从社会认知神经科学的视角探讨特质推理的神经机制是未来较有前途的一个方向。  相似文献

In list-method directed forgetting (LMDF), people are cued to forget a previously studied item list (List 1) and to learn a new list of items (List 2) instead. Such cuing typically enhances memory for the List 2 items, in both recall and (sometimes) item-recognition testing. It has recently been hypothesized that the enhancement effect for List 2 items (partly) reflects the result of a reset-of-encoding process. The proposal is that encoding efficacy decreases with an increase in study material, but the forget cue can reset the encoding process to make the encoding of early List 2 items as effective as the encoding of early List 1 items. An experiment is reported that examined the reset-of-encoding hypothesis with item-recognition testing, examining influences of items' serial learning position on the effects of the forget cue. Item-recognition tests were conducted separately for the two lists. Consistent with the reset-of-encoding hypothesis, the results showed strong enhancement effects for early List 2 items, but hardly any enhancement effects for middle and late List 2 items. Like in previous item-recognition studies, no cuing effects were found for List 1 items. The results support two-mechanism accounts of LMDF, which assume a critical role for a reset-of-encoding process for List 2 enhancement.  相似文献

ABSTRACT

Intrusive traumatic recollections suggest an inability in Posttraumatic Stress Disorder (PTSD) to control and notably to inhibit memories for trauma-related information. Supported by inhibitory deficits found on experimental settings in PTSD, memory functioning and memory biases in the disorder were usually explained through inhibitory and control deficits in the processing of trauma-related information. The present study aimed to directly assess this hypothesis by investigating memory control abilities for emotional information in PTSD. For this purpose, 34 patients diagnosed with PTSD were compared to 37 non-PTSD controls on an item-cued directed forgetting paradigm for emotional words combined with a Remember/Know recognition procedure. Results revealed enhanced amounts of Remember recognitions for trauma-related words in PTSD. Moreover, we replicated findings of memory control impairments in the disorder. However, such impairments only occurred for non-trauma-related words. Accordingly, it appeared that PTSD patients presented preserved memory control abilities for trauma-related words, at the expenses of other emotional valences. Surprisingly, PTSD patients presented a preserved ability to control and notably to inhibit their memory functioning for trauma-related material. In addition to potential theoretical and clinical relevance, these results are discussed in the light of resource reallocation hypotheses and vigilant-avoidant theories of information processing in PTSD.  相似文献

The role of anticipatory mechanisms in human memory control is poorly understood. Addressing the issue we investigated whether the presence of an anticipatory phase can enhance effects of cognitive control, as they occur during voluntary suppression of episodic memories. Using the Think/No-Think task, participants first learned several face–word associations, and thereafter were asked to either recall (think) or suppress (no-think) the word when provided with the word's face cue. In the one condition participants performed the Think/No-Think task in the presence of an anticipatory phase, giving participants the chance to prepare for memory suppression. In the other condition participants performed the task without such an anticipatory phase. On the final cued recall test participants were asked to recall all of the previously studied words. The results showed stronger forgetting of to-be-suppressed items in the presence than absence of the anticipatory phase. The finding is first evidence for the effectiveness of anticipatory mechanisms in human memory suppression.  相似文献

Tests have been shown to improve the later recall of tested information, a result known as the testing effect. Tests, however, can also impair the later recall of related information, an effect known as retrieval-induced forgetting. Although retrieval-induced forgetting has been demonstrated using a wide variety of materials, recent work suggests that learning information in the context of a coherent text passage may afford protection from retrieval-induced forgetting. In four experiments we explored the conditions under which retrieval-induced forgetting does and does not occur with such materials. We found that two factors—the coherence of the to-be-learned material and the competitiveness of retrieval practice—are important in determining whether retrieval-induced forgetting does or does not occur. Furthermore, even if retrieval-induced forgetting does occur, having the opportunity to restudy the forgotten information can prevent that forgetting from persisting. Taken together, these findings provide greater understanding of the costs and benefits of testing text materials, with possible implications for the optimisation of testing as a tool for learning in educational contexts.  相似文献

The objective was to examine whether the lower accessibility of studied items (Rp?) that follows retrieval practice with studied items from the same category (Rp+; retrieval-induced forgetting) is correctly monitored by our cognitive system. If monitored, lower confidence for Rp? items would be expected which, in turn, would allow the control of the retrieval-induced forgetting through the report option. In Experiment 1 the standard retrieval-practice paradigm with categorised word lists was followed by a recognition test with confidence rating and the option to report or withhold the answer. Accuracy showed retrieval-induced forgetting, but there were no differences in confidence. The report option did not affect retrieval-induced forgetting. The confidence–accuracy dissociation could be due to a correct monitoring of the retrieval-induced forgetting joined with a factor that incorrectly increases confidence for Rp? items. Familiarity with the practised category was proposed as this factor and tested in Experiment 2. Despite presenting the categories more times during the retrieval-practice phase to increase their familiarity, confidence ratings were unaffected. In conclusion, this research suggests that retrieval-induced forgetting was not monitored, giving rise to a confidence–accuracy dissociation.  相似文献

Selective retrieval practice of category exemplars often impairs the recall of related items, a phenomenon known as retrieval-induced forgetting (RIF). In Experiment 1 the role of item typicality (high, low) and presentation format of category exemplars (random, grouped) were analysed, while in Experiment 2 two encoding strategies (inter and intracategory) to modulate RIF were tested. Exemplar typicality was the critical factor underlying RIF. Competition during retrieval practice rendered RIF in the typical exemplars, but RIF did not appear when the exemplars were low typicality. The greater impairment of strong exemplars is in line with the inhibitory account of RIF and the notion of interference dependence. Inhibition appeared with random and grouped presentations suggesting that presentation format of the exemplars is not a critical factor in modulating RIF in a category-cued recall task. Distinctive processing instructions using sentences that connected items from different categories (intercategory strategy) and integration instructions by using size to organise the exemplars within categories (intracategory strategy) easily avoided competition and the need of inhibition processes in recall.  相似文献

People often think of themselves and their experiences in a more positive light than is objectively justified. Inhibitory control processes may promote this positivity bias by modulating the accessibility of negative thoughts and episodes from the past, which then limits their influence in the construction of imagined future events. We tested this hypothesis by investigating the correlation between retrieval-induced forgetting and the extent to which individuals imagine positive and negative episodic future events. First, we measured performance on a task requiring participants to imagine personal episodic events (either positive or negative), and then we correlated that measure with retrieval-induced forgetting. As predicted, individuals who exhibited higher levels of retrieval-induced forgetting imagined fewer negative episodic future events than did individuals who exhibited lower levels of retrieval-induced forgetting. This finding provides new insight into the possible role of retrieval-induced forgetting in autobiographical memory.  相似文献
