Premovement activity of the pre-supplementary motor area and the readiness for action: studies of time-resolved event-related functional MRI

The supplementary motor area (SMA) is thought to play in important role in the preparation and organisation of voluntary movement. It has long been known that cortical activity begins to increase up to 2s prior to voluntary self-initiated movement. This increasing premovement activity measured in EEG is known as the Bereitschaftspotential or readiness potential. Modern functional brain imaging methods, using event-related and time-resolved functional MRI techniques, are beginning to reveal the role of the SMA, and in particular the more anterior pre-SMA, in premovement activity associated with the readiness for action. In this paper we review recent studies using event-related time-resolved fMRI methods to examine the time-course of activation changes within the SMA throughout the preparation, readiness and execution of action. These studies suggest that the pre-SMA plays a common role in encoding or representing actions prior to our own voluntary self-initiated movements, during motor imagery, and from the observation of others' actions. We suggest that the pre-SMA generates and encodes motor representations which are then maintained in readiness for action.

Emotion dysregulation and adolescent psychopathology: a prospective study

Background

Emotion regulation deficits have been consistently linked to psychopathology in cross-sectional studies. However, the direction of the relationship between emotion regulation and psychopathology is unclear. This study examined the longitudinal and reciprocal relationships between emotion regulation deficits and psychopathology in adolescents.

Methods

Emotion dysregulation and symptomatology (depression, anxiety, aggressive behavior, and eating pathology) were assessed in a large, diverse sample of adolescents (N = 1065) at two time points separated by seven months. Structural equation modeling was used to examine the longitudinal and reciprocal relationships between emotion dysregulation and symptoms of psychopathology.

Results

The three distinct emotion processes examined here (emotional understanding, dysregulated expression of sadness and anger, and ruminative responses to distress) formed a unitary latent emotion dysregulation factor. Emotion dysregulation predicted increases in anxiety symptoms, aggressive behavior, and eating pathology after controlling for baseline symptoms but did not predict depressive symptoms. In contrast, none of the four types of psychopathology predicted increases in emotion dysregulation after controlling for baseline emotion dysregulation.

Conclusions

Emotion dysregulation appears to be an important transdiagnostic factor that increases risk for a wide range of psychopathology outcomes in adolescence. These results suggest targets for preventive interventions during this developmental period of risk.     

Psychoanalysis in Austria after 1933-34

Our essay focuses on major developments of the history of psychoanalysis during the fascist and National Socialist years in Austria and sheds light on the re-establishment of psychoanalysis after World War II. With the consolidation of National Socialism in Germany in 1933 and Austro-fascism in 1934, any psychoanalytical reflection that was critical of political and cultural trends was extinguished. Vienna - once again - became the center of the psychoanalytical movement in Central Europe, taking over the role Berlin had played during the twenties. But, during the Austro-fascist system, psychoanalysis was isolated from an important part of its public. Psychoanalysts reacted by adopting an attitude of political abstinence, accompanied by self-censorship, they concentrated on training and clinical work, or they went into exile. Austria's Anschluß to the National Socialist Third Reich led to the final destruction of psychoanalysis. Nearly all Viennese analysts were affected by the anti-Jewish measures of the National Socialists and almost all of them fled the country. During the war years, a small group of people under the leadership of August Aichhorn tried to continue psychoanalytic training. Its members refounded the Viennese Psychoanalytical Society in early 1946. But, scientific traditions were broken and tendencies of anti-enlightenment, especially clerical and catholic prejudices, had continued from the time of Austrofascism and Nationalsocialism. The last chapter of our essay summarizes the research topics and the main historiographical studies done in the field.

五四新文化运动与孔子观念的根本转折

五四新文化运动中的孔子观念需作系统的梳理与分析。五四新文化运动的健将们主要是基于对尊孔派的反感和伦理、文化上的彻底觉悟而发起了对孔子与孔家店集中而猛烈的批评与攻击。他们所批判的主要是孔子的偶像 ,而并不反对孔子本人 ,破除孔子偶像的束缚而使人们的思想从权威和偏见中彻底解放出来 ,这是新文化运动最重要的历史功绩 ;他们虽不反对孔子本人 ,但对孔子与孔子之道采取的是一种社会语境决定论的或历史化的诠释与读解的态度 ,故带来了孔子观念的根本转折。     

Avoidant instructions induce ironic and overcompensatory movement errors differently between and within individuals

Giving avoidant instructions can ironically result in the forbidden act being carried out, especially when the person is anxious or cognitive loaded. However, the consistency with which individuals make ironic errors across conditions remains unexamined. Forty participants were instructed to avoid moving a cursor above, below, left, and right when tracing an invisible line connecting two points while rehearsing seven-digit numbers on half of trials. Results showed that, without cognitive load, 26 participants made consistent overcompensatory movements, 10 made consistent ironic errors, and 4 showed no distinct error bias, with levels of somatic anxiety predicting this pattern. However, 21 (52.5%) participants changed their error tendency when cognitive loaded, indicating that movement effects of avoidant instruction were not experienced as general phenomena but rather differed between and within individuals. Overcompensatory errors made by participants grouped as overcompensatory performers under low load were significantly larger than the ironic errors made by participants grouped as ironic performers under low load, yet, paradoxically, ironic performers reported higher state and trait anxiety. Overall, results demonstrate a clear experimenter bias inherent in the use of avoidant instructions to direct participants' motor control.     

Making Critically Conscious Disciples: A Zambian Pentecostal Pneumato‐Discipleship Missiology

This article calls for rethinking of discipleship within missio Spiritus for political formation necessary for the viable functioning of Zambian Pentecostalism in the neo‐colonial context. It argues that the theme for the 2018 World Mission Conference in Arusha, Tanzania, “Moving in the Spirit: Called to Transforming Discipleship,” calls for pneumato‐discipleship in promoting human dignity. Through an empirical missiological approach, the article analyzes interviews conducted with various believers in various Pentecostal communities to demonstrate the emerging missio Spiritus praxis among Zambian Pentecostals, which seeks to promote a missional ethics of resistance to neo‐colonial political culture. Pneumato‐discipleship, as pedagogy for critically conscious disciples, is geared toward realization of human dignity. It is the instrument of hope in the search for dignity and struggle against pervasive inhumanities.     

Non-linear gaining in precision aiming: making Fitts' task a bit easier

The role of information in the processes underlying kinematic trajectory-formation was examined by manipulating the relation between effector space (movement of a hand-held stylus on a graphics tablet) and task space (movement of a cursor on a screen where targets were presented) in a precision aiming task with five different levels of task difficulty. Movement patterns were found to evolve as a function of the flow of information in task space, with participants (N = 13) producing more rapid and more fluent movements when the mapping between spaces included the softening-spring characteristics typical of behavioural patterns at higher levels of task difficulty. We conclude that the kinematic changes (movement time and pattern) observed when task difficulty increases result from informational influences. Information affects behavioural dynamics at the level of the parameters without affecting the underlying dynamical structure.
