Intra-individual variability on a computer-based working memory task was examined among 25 children/adolescents with ADHD and 24 typically developing peers. Participants completed the Visual Serial Addition Task (VSAT) and reaction time data were fit to an ex-Gaussian distribution. ADHD participants demonstrated significantly more variable performance than controls, and effects of working memory load were observed. Event rate, however, had no influence on group differences in performance. Follow-up correlations revealed associations between VSAT performance and ADHD symptomatology. This study supports intra-individual variability as a hallmark feature of ADHD beyond the domain of response inhibition and reinforces the need to consider variability in ADHD more broadly. 相似文献

The authors examined how time orientation and morningness—eveningness relate to 2 forms of procrastination: indecision and avoidant forms. Participants were 509 adults (M age = 49.78 years, SD = 6.14) who completed measures of time orientation, morningness—eveningness, decisional procrastination (i.e., indecision), and avoidant procrastination. Results showed that morningness was negatively related to avoidant procrastination but not decisional procrastination. Overall, the results indicated different temporal profiles for indecision and avoidant procrastinations. Avoidant procrastination related to low future time orientation and low morningness, whereas indecision related to both (a) high negative and high positive past orientations and (b) low present-hedonistic and low future time orientations. The authors inferred that distinct forms of procrastination seem different on the basis of dimensions of time. 相似文献

Analytic writing constitutes a literary genre of its own. It involves the linking of an analytic idea (developed in a scholarly manner) with an analytic experience created in the medium of language. What makes this literary genre so demanding is that experience-including analytic experience-does not come to us in words. This fact generates a paradox that lies at the core of analytic writing: analytic experience (which cannot be said or written) must be transformed into 'fi ction' (an imaginative rendering of experience in words) in order to convey to the reader something of what is true to the emotional experience that the analyst had with the patient. The author discusses a clinical passage from one of his recently published papers in an effort to demonstrate some of the conscious and unconscious thinking that goes into his writing. He then looks closely at the way the language works in a successful piece of theoretical analytic writing. The paper concludes with a discussion of a number of facets of the author's experience with analytic writing including the psychological 'state of writing', which is at once a meditation and a wrestling match with language; experimenting with the form (structure) of an analytic essay; and the question of originality in analytic writing. 相似文献

Prior research has found a relationship between perceived facial attractiveness and perceived personal trustworthiness. We examined the time course of attractiveness relative to trustworthiness evaluation of emotional and neutral faces. This served to explore whether attractiveness might be used as an easily accessible cue and a quick shortcut for judging trustworthiness. Detection thresholds and judgment latencies as a function of expressive intensity were measured. Significant correlations between attractiveness and trustworthiness consistently held for six emotional expressions at four intensities, and neutral faces. Importantly, perceived attractiveness preceded perceived trustworthiness, with lower detection thresholds and shorter decision latencies. This reveals a time course advantage for attractiveness, and suggests that earlier attractiveness impressions could bias trustworthiness inferences. A heuristic cognitive mechanism is hypothesised to ease processing demands by relying on simple and observable clues (attractiveness) as a substitute for more complex and not easily accessible information (trustworthiness). 相似文献

This study used a dual task with participants of different levels of cognitive capacities, assessed with neuropsychological tests, to examine the attentional cost on time judgment of processing concurrent temporal and non-temporal information. Children and adults performed a temporal reproduction task with either an interfering temporal or non-temporal discrimination task. The results showed an underestimation of time in the dual task compared to the single task, the extent of which was directly linked to individual attentional capacities. However, the non-temporal task interfered more than the temporal task on the reproduced durations. Nonetheless, the temporal reproduction task equally affected performance in the non-temporal and the temporal discrimination task. These results reveal the predominant role of the cost of dual-tasking in interference effects on time judgment, and the lesser role of concurrent information, especially of temporal information. This suggests a lack of competition for attentional resources in the processing of multiple durations. 相似文献

In Being and Time, Heidegger affirms that being-with or Mitsein is an essential constitution of Dasein but he does not submit this existential to the same rigorous analyses as other existentials.
In this essay, Jean-Luc Nancy points to the different places where Heidegger erased the possibility of thinking an essential
with that he himself opened. This erasure is due, according to Nancy, to the subordination of Mitsein to a thinking of the proper and the improper. The polarization of Being-with between an improper face, the Anyone, and a proper one, the people, which is also, as Nancy shows, a polarization between everydayness and historicity, between a being-together in exteriority
(indifference and anonymity) and a being-together in interiority (union through destiny), between a solitary dying and the
sacrificial death in combat, leaves the essential with unthought. This essay shows not only the tensions that arise out of Heidegger’s own analyses of Mitsein and affect the whole
of Being and Time but also underlines in the end a “shortfall in thinking” inherent not only to Heidegger’s work but, as Nancy claims, to our
Western tradition, a shortfall which Nancy has attempted to remedy in his Being Singular Plural.
A slightly different version has been published under the title “L’être-avec de l’être-là” in Lieu-Dit 19 “Communauté” (Spring 2003). All additions in square brackets are the translators’ unless otherwise indicated. The German
words in parentheses are Nancy’s additions. For the translation of citations from Being and Time, we have used the Macquarrie & Robinson’s translation which we have modified only when constrained by Nancy himself. Overall,
we have tried to be faithful to the Heideggerian tone of Nancy’s text by using the accepted English translation of the central
concepts of Being and Time. When we depart from the accepted translations, it is to remain true to Nancy’s paraphrases, emphases, and displacements.
For example, we refrain from using “authentic” and “inauthentic.”

Intra-individual reaction time variability (IIV) in neuropsychological task performance reflects short term fluctuations in performance. Increased IIV has been reported in patients with schizophrenia and could be related to a deficient neural timing mechanism, but the role of IIV in adult patients with other psychiatric disorders has not been established. Therefore, we compared IIV measures obtained in a Go/Nogo task from patients with schizophrenia, major depression and borderline personality disorder. IIV was increased for patients with schizophrenia. When correcting for differences in mean reaction time, depressive and borderline patients also showed increased IIV. Importantly, all groups showed a strong association between IIV and accuracy of task performance. This suggests that increased IIV might be a sensitive marker for the efficiency of top-down attentional control in all diagnostic groups. Aside from these similarities, the complete results including measures of IIV, mean reaction time and accuracy show differential patterns for patients with schizophrenia compared to those with borderline personality disorder or depression. These results are discussed with respect to common versus disorder-specific neural mechanisms underlying increased IIV. 相似文献

启动实验的有效条件之一是,控制组和实验组的目标词在基线反应时上相同,但在实际操作中,不少研究没有收集基线反应时,只是确保了两组目标词在频率上相同.本研究实验结果显示:对于母语而言,如果词频很高,相同频率的词得到相同反应时的机率很大;相反,机率就比较低;对于外语而言,这种机率相对更低.实验说明,相同词频的词不一定能得到相同的反应时,因此收集基线反应时是启动实验不可或缺的步骤. 相似文献
