An evaluation of matrix training to teach college students piano notes and rhythms

Twelve college students learned to tact the names of notes and rhythms and play them when presented with compound stimuli (visuals of notes and rhythms on a musical staff). In Experiment 1, we assessed generalization by presenting novel notes, rhythms, and compound stimuli not previously paired together. In the second experiment, we added a metronome that played at 60 beats per minute in all conditions for 3 out of 6 participants to ensure consistent tempo. Across both experiments, participants passed almost all posttests with the exception of tacting and playing in the presence of sound clips. Our data suggest that matrix training is an effective procedure to teach music skills to college students.     

Intentional action processing results from automatic bottom-up attention: An EEG-investigation into the Social Relevance Hypothesis using hypnosis

Social stimuli grab our attention. However, it has rarely been investigated how variations in attention affect the processing of social stimuli, although the answer could help us uncover details of social cognition processes such as action understanding. In the present study, we examined how changes to bottom-up attention affects neural EEG-responses associated with intentional action processing. We induced an increase in bottom-up attention by using hypnosis. We recorded the electroencephalographic μ-wave suppression of hypnotized participants when presented with intentional actions in first and third person perspective in a video-clip paradigm. Previous studies have shown that the μ-rhythm is selectively suppressed both when executing and observing goal-directed motor actions; hence it can be used as a neural signal for intentional action processing. Our results show that neutral hypnotic trance increases μ-suppression in highly suggestible participants when they observe intentional actions. This suggests that social action processing is enhanced when bottom-up attentional processes are predominant. Our findings support the Social Relevance Hypothesis, according to which social action processing is a bottom-up driven attentional process, and can thus be altered as a function of bottom-up processing devoted to a social stimulus.     

Delayed Sleep Timing in Obsessive-Compulsive Disorder Is Associated With Diminished Response to Exposure and Ritual Prevention

Exposure and ritual prevention (ERP) and pharmacotherapy are typically associated with significant symptom reductions for individuals with obsessive-compulsive disorder (OCD). However, many patients are left with residual symptoms and other patients do not respond. There is increasing evidence that delays in sleep timing/circadian rhythms are associated with OCD but the potential effects of delays in sleep timing on ERP warrant attention. This paper presents data from 31 outpatients with OCD who participated in ERP. Results showed that delayed sleep timing was common and that individuals with delayed bedtimes benefited significantly less from treatment and were significantly more likely to be nonresponders compared to individuals with earlier bedtimes. Further, the effects of sleep timing remained statistically significant even after controlling for global sleep quality, negative affect, and several other variables. These findings add to a growing literature suggesting the utility of better understanding the role of disruptions in the timing of sleep in OCD.     

A Reappraisal of the Role of Muḥibb al-Dīn al-Khaṭīb and the YMMA in the Rise of the Muslim Brotherhood

In contemporary academic literature, the name of the Syrian publisher and journalist Mu?ibb al-Dīn al-Kha?īb often appears in connection with the rise of the Muslim Brotherhood during the interwar years. Although his role in the transition of ?asan al-Bannā's movement from a marginal to a significant socio-political player in Egyptian affairs has been mentioned in numerous works, no comprehensive study has yet been undertaken to determine how and by what means exactly al-Kha?īb supported al-Bannā's organization in its early years. The following article is an attempt to answer these questions by showing the strategic importance of al-Kha?īb and his network in helping al-Bannā develop from being an Arabic teacher in a primary school to one of the main leaders of the Islamist movement in Egypt.     

The rehabilitation of primary object relations in the first year of intensive therapy with a severely deprived child

The following is an account of the first year of a therapy carried out in the public sector of a child born at the beginning of 1990 in an eastern European country and brought up in a home for abandoned children until he was placed with Italian parents at the end of 1995. I shall describe the child's initial psychological state, vigorous, but desperate, and then go on to describe the course of the first year of therapy, focusing in particular on the sessions of the from period, in which, apart from the quality and intensity of his anxiety, his need to fie this anxiety by retracing the stages of his first object experiences is clear.     

Tradition,Reason, and Qur’anic Exegesis in the Modern Period: The Hermeneutics of Said Nursi

Key figures in modernist Qur’an exegesis include Sayyid Ahmad Khan (d. 1898) and Muhammad ?Abduh (d. 1905). This article presents the exegetical principles of Bediuzzaman Said Nursi (1877–1960), a Muslim thinker and a major twentieth-century Turkish scholar who is not necessarily to be labelled a ‘modernist’, on tafsīr bi-al-ma?thūr (tradition-based exegesis) and tafsīr bi-al-ra?y (reason-based exegesis) with special reference to the views of early Muslim modernist thinkers. It particularly refers to Nursi’s work on u?ūl al-tafsīr, Mu?ākamāt (Reasonings), and his one-volume commentary, Ishārāt al-i?jāz (Signs of Inimitability), in order to understand his method of tafsīr. The purpose of the article is to place Nursi within the historical framework of Qur’an exegesis and it argues that, while there are some similarities between ?Abduh and Nursi since the latter is influenced by the former, the methodological differences are clear. While ?Abduh’s method is text-based, Nursi’s is based on kalām (Islamic theology). While ?Abduh is critical of the classical style tafsīr and linguistic discussions in tafsīr, Nursi can be considered to be a modern representative of the Ottoman exegetical school and a follower in the way of al-Zamakhsharī (d. 538?1144), Fakhr al-Dīn al-Rāzī (d. 606?1210) and al-Bay?āwī (d. 685/1286).     

An extended motor network generates beta and gamma oscillatory perturbations during development

This study examines the time course and neural generators of oscillatory beta and gamma motor responses in typically-developing children. Participants completed a unilateral flexion–extension task using each index finger as whole-head magnetoencephalography (MEG) data were acquired. These MEG data were imaged in the frequency-domain using spatial filtering and the resulting event-related synchronizations and desynchronizations (ERS/ERD) were subjected to voxel-wise statistical analyses to illuminate time–frequency specific activation patterns. Consistent with adult data, these children exhibited a pre-movement ERD that was strongest over the contralateral post-central gyrus, and a post-movement ERS response with the most prominent peak being in the contralateral precentral gyrus near premotor cortices. We also observed a high-frequency (∼80 Hz) ERS response that coincided with movement onset and was centered on the contralateral precentral gyrus, slightly superior and posterior to the beta ERS. In addition to pre- and post-central gyri activations, these children exhibited beta and gamma activity in supplementary motor areas (SMA) before and during movement, and beta activation in cerebellar cortices before and after movement. We believe the gamma synchronization may be an excellent candidate signal of basic cortical motor control, as the spatiotemporal dynamics indicate the primary motor cortex generates this response (and not the beta oscillations) which is closely yoked to the initial muscle activation. Lastly, these data suggest several additional neural regions including the SMA and cerebellum are involved in basic movements during development.     

基于自发脑电的脑机接口研究进展

脑机接口是一种不依赖于外周神经和肌肉等常规输出通道的信息交流系统,近年来发展非常迅速。它可为神经肌肉障碍患者提供一条与外界沟通的途径,并在虚拟现实、游戏娱乐和航空等领域具有潜在价值。目前,脑机接口中常用的脑电输入信号包括P300、稳态视觉诱发电位（SS—VEP）、皮层慢电位（SCP）以及μ或β节律等。其中,SCP、μ或β节律等自发脑电不依赖于额外刺激的输入,不会产生视觉疲劳,没有适应性的问题,且其神经生理学基础已获得比较深入的研究,因而在脑机接口中得到了较多的应用。但是,基于自发脑电的脑机接口也存在明显的缺陷,如并非所有个体都适用基于汕节律的脑机接口,基于SCP的脑机接口要经过长时间的训练才能实现等。     

王家台《归藏》与《穆天子传》

1993年3月,湖北江陵王家台15号秦墓中出土了《归藏》。王家台《归藏》举世瞩目,一些学者认为它就是商易。本文根据王家台《归藏》内容多出《穆天子传》本事的事实,认定王家台《归藏》必成书于《穆天子传》之后,属战国作品。本文还进一步分析了学术史上的相关问题,以为类似王家台《归藏》的内容很可能在西晋汲冢所出书中就已经发现。     

Clustering in the output of behavior

Pigeons exposed to fixed-interval schedules of 3, 5, 15, 40, and 120 minutes all maintained considerable variability in daily response rates for as many as 104 sessions. However, variations did not occur at random. Instead, rate in a session appeared dependent on those occurring previously. The series displayed a wave-like form arising because a group of high rates was followed by a group of low rates and vice versa. These sequential relations produced a curve having irregular periodicity, sometimes superimposed on a declining or rising linear trend. Whether grouping of response rates stemmed from experimental or extra-experimental sources was not determined. If the phenomenon was either totally or partially produced by the schedule itself, it suggests that response rate is determined by a combination of positive and negative feedback. Control by factors extrinisic to the experiment itself implies that response rate may be influenced by some rhythmic physiological process.
