Re-enactments in their developmental context

The power of the repetition compulsion is felt in an especially keen way during re-enactments within psychodynamic psychotherapy. In this paper, the authors recommend greater attention to the developmental aspects of re-enactments as providing valuable information about the affective character of the crisis being brought to life in the treatment. Specifically, the authors suggest that the current developmental stage of the patient influences the experience and expression of the core developmental conflict that lies at the heart of the re-enactment in the treatment dyad. Re-enactments in childhood, adolescence and young adulthood, as well as at midlife and in the later years, each have different signatures. Thus, increased knowledge and awareness of both developmental stage and developmental core conflict is important for the following reasons: It provides a firmer theoretical foundation for understanding what is, by definition, a formidable moment in treatment; it adds another dimension and thus enhanced flexibility to the clinician’s clinical stance during a time of greater countertransference potential; and it adds to the theoretical perspective that the compulsion to repeat functions, at least in part, as an attempt to master an intrapsychic, affectively charged, previous experience of defeat. Clarifying the developmental nature of re-enactments for both patient and therapist can serve an orienting function during what is often a confusing and destabilizing time in the treatment relationship, and it can help differentiate developmentally appropriate behaviour from re-enacted conflict.     

重复启动对时序知觉的影响

在时序判断任务中,重复启动导致被试把启动的靶刺激知觉为先出现的。知觉加工增强观和决策反应偏向观都试图解释其机制,但仍存在争议。本研究采用图形材料,通过三个实验系统考察了重复启动对时序知觉的影响。实验结果显示,启动和指导语都具有显著效应。这说明,重复启动对时序知觉的影响涉及知觉加工和决策水平两个方面。实验还首次发现,在启动的靶刺激先出现时发生了重复启动效应的反转。最后,研究提出了双加工表征匹配调节假说,用以综合解释目前的研究结果     

Nonword repetition and identification skills in Kannada speaking school-aged children who do and do not stutter

PurposeThe present study employed nonword repetition and nonword identification tasks to explore the phonological working memory (PWM) abilities and its interaction with speech motor control in school-aged children who do and do not stutter.MethodParticipants were 17 children who stutter (CWS) (Age range = 7–12) and 17 age and gender-matched children who do not stutter (CWNS). For the nonword repetition task, the participants repeated sets of 2-, 3-, and 4-syllable nonwords (n = 12 per set). The participants silently identified a target nonword from a subsequent set of three nonwords (n = 12 per 2-, 3- and 4-syllable length) for the nonword identification task. The performance of CWS on the nonword repetition task was compared with the CWNS for the mean number of accurate repetitions, number of trials taken, number of accurate repetitions on initial trial, and number of fluent repetitions across the three-syllable conditions for the tasks. For the nonword identification task, the number of nonwords identified accurately by the two groups were subjected to analysis.ResultsCWS were significantly less accurate on the initial production of nonwords and required significantly more number of attempts to repeat the nonword accurately. Further for the nonword identification task, CWS were significantly less accurate than CWNS in correctly identifying the target nonword.ConclusionsThe present findings suggest that, in addition to limitations in PWM capacity, an unstable speech motor control system in CWS may lead to dysfluent speech.     

任务切换中的反应重复效应

在任务重复试次中反应的重复对反应有促进作用,而在任务切换试次中反应的重复对反应有阻碍作用,此现象即为反应重复效应（response repetition effects, RRE）。RRE普遍存在不同任务切换范式中,是一种抽象反应编码重复效应,受刺激效价和一致性、反应编码重复度和准备时间等因素影响。其理论解释主要有重构论、启动-抑制论、以及情境检索说。现有研究初步表明前额叶皮层是RRE的关键脑区,但RRE的认知神经机制及理论解释还有待进一步探讨。     

Homotopic language reorganization in the right hemisphere after early left hemisphere injury

Speech production is inextricably linked to speech perception, yet they are usually investigated in isolation. In this study, we employed a verbal-repetition task to identify the neural substrates of speech processing with two ends active simultaneously using functional MRI. Subjects verbally repeated auditory stimuli containing an ambiguous vowel sound that could be perceived as either a word or a pseudoword depending on the interpretation of the vowel. We found verbal repetition commonly activated the audition-articulation interface bilaterally at Sylvian fissures and superior temporal sulci. Contrasting word-versus-pseudoword trials revealed neural activities unique to word repetition in the left posterior middle temporal areas and activities unique to pseudoword repetition in the left inferior frontal gyrus. These findings imply that the tasks are carried out using different speech codes: an articulation-based code of pseudowords and an acoustic-phonetic code of words. It also supports the dual-stream model and imitative learning of vocabulary.     

Repetition in visual word identification: Benefits and costs

University students performed lexical tasks with visually presented target words after the presentation of an identical or unrelated prime, at short (80–120?ms) or longer (410–710?ms) prime–target stimulus onset asynchronies (SOAs). Experiment 1 showed perceptual identification benefits in vocal responding at a short SOA that were reduced (accuracy) or reversed (latency) at a longer SOA. Experiment 2 showed a transition from a repetition benefit to a cost over 3 SOAs in a target-masked version of the lexical decision task (LDT; target displayed for only 141?ms). In Experiment 3 the repetition cost was replicated at a 530-ms SOA in the LDT with masked targets, but a repetition benefit was observed in the conventional LDT (target displayed until response). The dependence of repetition costs on target masking is more consistent with biases based on episodic confusions than refractoriness of lexical representations.     

Repetition advantage and disadvantage in perceptual identification tasks

Repetitive presentation of a stimulus brings not only advantage but also disadvantage when performing perceptual identification tasks. In this study, the conflicting phenomena of the effect of repetition were examined using two Kana character sets (Hiragana and Katakana) as stimuli. Two identical or different stimuli were presented in rapid succession and participants were asked to identify and report them. The stimulus onset asynchrony (SOA) between the two stimuli was varied from 200 ms to 1200 ms, according to which the suitable temporal conditions for the two distinct effects of repetition were explored. The results indicated that two distinct effects of repetition occurred depending on the informational code shared by the two stimuli. An interference effect of repetition was observed with SOA values of up to 500 ms when the two stimuli were identical in terms of their visual pattern code (Hiragana), whereas a superior effect of repetition was observed with an SOA value of 200 ms when they were identical only in terms of their phonological code (Hiragana and Katakana). From these findings, the author proposes that when two identical stimuli are presented in rapid succession, inhibition and activation mechanisms may function at different levels of processing.     

Here Today,Gone Tomorrow? Assessing How Timing and Repetition of Scandal Information Affects Candidate Evaluations

Scholars and political consultants alike know that during a campaign even the hint of a scandal has the potential to distract from a candidate's policy messages—or even worse—can have dire consequences on Election Day. But does it matter whether the scandal breaks early as opposed to late in the campaign? And how do citizens respond when the scandal drags on for weeks? This study represents the first effort to shed light on these temporal dynamics. Results reveal that timing affects the immediate impact of scandal information, the rate at which those initial effects decay, and candidate evaluations offered at the campaign's conclusion. Additionally, I develop two competing hypotheses regarding how citizens may process scandal information when it is repeated throughout a campaign. Empirical tests suggest that voters eventually reach a saturation threshold after which additional repetition of scandal information has negligible effects on evaluations unless new details are a prominent feature of ongoing coverage, in which case repetition can extend the negative effects of scandal.

On the reception of the concept of the death drive in Germany: expressing and resisting an ‘evil principle’?

With Beyond the Pleasure Principle, Freud attempted ‘to describe and to account for the facts of daily observation in our field of study’ (1920, p. 7), in particular concerning destructive clinical phenomena that confront us in the analytic situation: traumatic neuroses, melancholic states, negative‐therapeutic reactions, masochism, repetition compulsion and so on. The author demonstrates in the first section how Freud's own resistance – later self‐diagnosed – to recognizing these unwelcome facts was expressed in the terminological and conceptual ambiguities of the death drive hypothesis then introduced, ambiguities that to some extent continue to impede the reception of its clinical usefulness to this day. As soon as Freud had demonstrated the connection with clinical practice more directly in The Ego and the Id (1923), some contemporaries adopted it as a helpful clinical concept, while others believed that they could (and must) refute it. The second part outlines its reception in the 1920s and 1930s, which was part of an international discussion that was, of course, initially conducted mainly in German. The beginnings of an important further development of the death drive hypothesis are described in a separate section because it originated from Melanie Klein's earliest experiences in analysing children in Berlin in the early to mid‐1920s. She referred at that time to an ‘evil principle’, and in 1932 published her view of the death drive hypothesis, which was further developed in subsequent decades by her and her followers in London. In this period, conditions changed dramatically: in Germany Freud's books (among others) were burnt, crimes against humanity were instigated and psychoanalysis ceased to exist in this country. Almost all the analysts who published on the death drive had to emigrate. From then on, entirely different discourses took place in the various regions. In Germany, the death drive hypothesis was (largely) disregarded or rejected for decades after the Holocaust. Frank demonstrates how the uncritical recourse in relevant works to this day to an article by Brun in 1953 that considered the death drive to have been comprehensively refuted on the basis of (apparently) comprehensive literature research can be understood as a symptom. Pursuing some reflections by Beland (1988) and Cycon (1995), the author expounds her thesis that in Germany the clinical usefulness of the death drive hypothesis could not be considered as long as destructive impulses were still an immediate social reality. According to the author's observations, in stating that there had been a ‘definite reaction formation against death drive hypotheses’, Brun had unintentionally made an accurate diagnosis. It was not until the realization of inevitable perpetrator identifications (‘Hitler in us’) in this country became (more widely) possible that a concern with the death drive hypothesis could also resume. In the final section, the author takes up one line of this development and traces how some German analysts in the 1980s came into contact with Kleinian developments that had since occurred and how these found and find their way into their analytic working. She closes by asking whether it might be appropriate to consider Melanie Klein's concept of an evil principle – along with the pleasure and reality principles – as a less ambiguous one for the phenomena under consideration.
