Life,the Unhistorical,the Suprahistorical: Nietzsche on History

Abstract

Nietzsche was a philosopher who prided himself, in deliberate contradistinction with previous philosophers, on his ‘historical sense’. But this leaves many questions unanswered about the precise role of the historical in Nietzsche’s philosophy. Perhaps most importantly, can the conception of genealogy in Nietzsche’s later philosophy, as a revised historical method, be taken to represent his mature philosophical methodology in general? I argue, firstly, that there is considerable continuity between Nietzsche’s conceptions of history in the early essay ‘On the uses and disadvantages of history for life’ and those of his later philosophy. The former can therefore be used as a resource for understanding the latter. Through a reading of the early history essay I demonstrate that Nietzsche’s conception of the historical here is intimately bound up with the notion of the ‘unhistorical’ and that it is precisely renewed access to the unhistorical which is required in order for history to be conducive to the flourishing of humanity. I go on to contend that this holds for Nietzsche’s later writings as well, and that genealogy, being purely historical, must therefore be seen as one subsidiary part of a broader philosophy in which the unhistorical will play, literally, a vital role.     

Anticipation boosts forgetting of voluntarily suppressed memories

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.     

The subjective experience of retrieval-induced forgetting

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.     

The role of exemplar typicality and encoding strategies in category retrieval-induced forgetting

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.     

Retrieval-induced forgetting,delay, and sleep

Retrieval-induced forgetting (RIF) refers to the finding that retrieval of a subset of previously studied material can cause forgetting of related unpractised material. Prior work on the role of delay between practice and test for RIF reported mixed results. Whereas some studies found RIF to be a relatively transient phenomenon, others found RIF to persist over time. We examined whether the persistence of RIF can depend on whether wakefulness or sleep follows retrieval practice. We employed a variant of the retrieval-practice paradigm with short (20 minutes) and long (12 hours) delay conditions. In all conditions participants studied a perceptually categorised list followed by retrieval practice on some of the items from some of the categories. Participants studied and practised the material in the morning or the evening. RIF was present in the short-delay conditions, and it was present in the long-delay condition if the delay included nocturnal sleep; if the long delay was filled with diurnal wakefulness, RIF was absent. Results show that whether delay eliminates RIF or not can depend on whether sleep or wake follows retrieval practice. Connections of the results to recent findings about the role of delay and sleep for RIF are discussed.     

Stop crying! The impact of situational demands on interpersonal emotion regulation

ABSTRACT

Crying is a common response to emotional distress that elicits support from the environment. People may regulate another’s crying in several ways, such as by providing socio-affective support (e.g. comforting) or cognitive support (e.g. reappraisal), or by trying to emotionally disengage the other by suppression or distraction. We examined whether people adapt their interpersonal emotion regulation strategies to the situational context, by manipulating the regulatory demand of the situation in which someone is crying. Participants watched a video of a crying man and provided support by recording a video message. We hypothesised that when immediate down-regulation was required (i.e. high regulatory demand), participants would provide lower levels of socio-affective and cognitive support, and instead distract the crying person or encourage them to suppress their emotions, compared to when there is no such urgency (i.e. low regulatory demand). As predicted, both self-reported and behavioural responses indicated that high (as compared to low) regulatory demand led to a reduction in socio-affective support provision, and a strong increase in suppression and distraction. Cognitive support provision, however, was unaffected by regulatory demand. When the context required more immediate down-regulation, participants thus employed more regulation strategies aimed at disengaging from the emotional experience. This study provides a first step in showing that people take the context into account when attempting to regulate others’ emotions.     

Understanding action language modulates oscillatory mu and beta rhythms in the same way as observing actions

The mu rhythms (8–13 Hz) and the beta rhythms (15 up to 30 Hz) of the EEG are observed in the central electrodes (C3, Cz and C4) in resting states, and become suppressed when participants perform a manual action or when they observe another’s action. This has led researchers to consider that these rhythms are electrophysiological markers of the motor neuron activity in humans. This study tested whether the comprehension of action language, unlike abstract language, modulates mu and low beta rhythms (15–20 Hz) in a similar way as the observation of real actions. The log-ratios were calculated for each oscillatory band between each condition and baseline resting periods. The results indicated that both action language and action videos caused mu and beta suppression (negative log-ratios), whereas abstract language did not, confirming the hypothesis that understanding action language activates motor networks in the brain. In other words, the resonance of motor areas associated with action language is compatible with the embodiment approach to linguistic meaning.     

目标词效价对思维压制即刻激活效应的影响

思维压制指的是个体有意识、有目的地将某一目标思维从意识中移除的心理过程。压制某目标思维会产生矛盾效应,即试图压制反而会激活被压制目标。本研究采用思维压制的即刻测量(online measure)范式,通过两个实验对压制是否会产生即刻激活效应(immediate enhancement effect)以及目标词效价如何影响该效应进行了检验。结果发现:压制负性词时出现了即刻激活效应,而压制正性词时并未出现上述效应。由此推论,被压制目标词的威胁性,可能是影响即刻激活效应是否出现的一个因素。

Retrospective revaluation effects following serial compound training and target extinction

Using a conditioned suppression task, two experiments examined retrospective revaluation effects after serial compound training in a release from overshadowing design. In Experiment 1, serial X → A+ training produced suppression to target A, which was enhanced when preceded by feature X, whereas X by itself elicited no suppression. Subsequent A− presentations extinguished responding to A, but had no effect on either responding to X → A or X alone. However, the addition of A− trials did enhance the ability of feature X to elicit suppression to a novel target, B, suggesting retrospective revaluation of X’s properties. Experiment 2 showed that the enhanced transfer effect, observed in Experiment 1, was independent of the training history of the target (B− or Y → B+/B−). Together, these results suggest that feature X did not retrospectively acquire excitatory strength or occasion setting power, but rather a generalized ability to increase responding to any other cue.
