PSO-GA based hybrid with Adam Optimization for ANN training with application in Medical Diagnosis

This paper introduces a novel PSO-GA based hybrid training algorithm with Adam Optimization and contrasts performance with the generic Gradient Descent based Backpropagation algorithm with Adam Optimization for training Artificial Neural Networks. We aim to overcome the shortcomings of the traditional algorithm, such as slower convergence rate and frequent convergence to local minima, by employing the characteristics of evolutionary algorithms. PSO has a property of faster convergence rate, which can be exploited to account for the slower pace of convergence of the traditional BP (which is due to low values of gradients). In contrast, the integration with GA complements the drawback of convergence to local minima as GA, possesses the capability of efficient global search. So by this integration of these algorithms, we propose our new hybrid algorithm for training ANNs. We compare both the algorithms for the application of medical diagnosis. Results display that the proposed hybrid training algorithm, significantly outperforms the traditional training algorithm, by enhancing the accuracies of the ANNs with an increase of 20% in the average testing accuracy and 0.7% increase in the best testing accuracy.     

多感觉整合中的声音诱发闪光错觉效应

声音诱发闪光错觉效应是典型的视听整合错觉现象, 是指当视觉闪光刺激与间隔100 ms内的听觉声音刺激不等数量呈现时, 被试知觉视觉闪光的数量与听觉声音的数量相等。声音诱发闪光错觉的影响因素既包括自下而上和自上而下的被试内差异因素, 也包括视听刺激依赖程度、视听整合的发展和视听刺激知觉敏感性等被试间差异因素。该效应的产生在时程上主要体现在早期加工阶段, 在脑区上主要涉及多处皮层及皮层下相关脑区。未来研究应进一步考察注意、奖赏和视听整合方式等认知加工对声音诱发闪光错觉的影响, 同时也应该关注声音诱发闪光错觉对记忆和学习的影响以及结合计算模型和神经科学的手段进一步探讨其认知神经机制。     

Opening the closed heart: affect-focused clinical work with the victims of early trauma

This paper begins with the understanding that early trauma leads to powerful dissociative defenses which injure the capacity to feel. It further explores ways to restore this capacity through body-centred attention to affect-in-the-moment in the psychoanalytic situation. Using the author’s personal experience while in analysis as well as a case of severe early trauma, he demonstrates the consciousness-killing effect of primitive defenses and shows how body-sensitive techniques hold the promise of restoring the patient’s sense of aliveness and hence, opening the unconscious to those affect-images that are the building blocks of the human imagination. A final section focuses on the neglect of feeling in Jungian psychology and suggests that the “creation of consciousness” which Jung described as his personal myth, is quintessentially a process of emotional transformation – of bringing unconscious suffering into consciousness – as feelings.     

The construct of the ‘mana personality’ in Jung’s works: a historic-hermeneutic perspective. Part I

According to Jung, the ‘mana personality’ represents an archetypal phase of the individuation process of remarkable interest in psychological, hermeneutic and theoretical terms. This figure is characterized by a high initiatic potential that fosters the approximation of the consciousness of the Self. At the same time, it entails a risk of psychic inflation or of ‘similarity to God’. In this article, divided in two parts, I deal with those aspects through a reconstruction of the development of this notion within Jung’s published works, adopting a primarily chronological and, secondarily, thematic approach moving from a textual analysis of relevant passages. In this first part, I consider some passages which deal mainly with the risks of the assimilation of the unconscious in ‘La structure de l’inconscient’ (1916) that preceded the successive proper treatment of the mana personality’s notion presented, and here examined, in ‘The relations between the ego and the unconscious’ (1928). Successively, I take into consideration some further issues related to it discussed by Jung in ‘The structure of the psyche’ (1928/1931), ‘Archaic man’ (1931), and ‘Nietzsche’s Zarathustra’.     

The construct of the ‘mana personality’ in Jung’s works: a historic-hermeneutic perspective. Part II

This is the second part of an article that tries to provide a framework of understanding of, and a seminal reflection on, a highly interesting yet little explored psychological construct of Jung’s analytical psychology, namely the ‘mana personality’. Here I take into consideration some issues around the ‘saviour complex’, discussed in Jung’s seminar on Nietzsche’s Zarathustra, concerning both the psychological analysis of the individual and the socio-political level related to the collective horizon of the 1930s. Moreover, I consider the continuity of Jung’s analysis of such issues in other works such as ‘Psychology and national problems’ (1936), Symbols of Transformation (1952), and Aion (1950). I finally make some suggestions concerning Jung’s apparent hermeneutic tendency to apply the construct of the mana personality to collective historical phenomena.     

Links Between Reactive Attachment Disorder,Caregiving and Temperament: A Differential Susceptibility Perspective

Abstract

The links between Reactive Attachment Disorder (RAD) and temperament received relatively little research attention, in spite of their clinical and social relevance. Children with RAD sustain disproportionate burdens of early adversity related to their caregiving environment. However, there seem to be important individual differences in susceptibility to adversity, since only a small number of children show signs of RAD. Based on the work of Zeanah and Fox, this review aims to bring new insights to this relevant clinical issue in light of recent research. A differential susceptibility hypothesis will be considered as a promising and innovative approach toward a further understanding of the links between temperament and RAD.     

Does Object Height Affect the Dart Throwing Motion Angle during Seated Activities of Daily Living?

Abstract

Complex wrist motions are needed to complete various daily activities. Analyzing the multidimensional motion of the wrist is crucial for understanding our functional movement. Several studies have shown that numerous activities of daily livings (ADLs) are performed using an oblique plane of wrist motion from radial-extension to ulnar-flexion, named the Dart Throwing Motion (DTM) plane. To the best of our knowledge, the DTM plane angle performed during ADLs has not been compared between different heights (e.g. table, shoulder and head height), as is common when performing day-to-day tasks. In this study, we compared DTM plane angles when performing different ADLs at three different heights and examined the relationship between DTM plane angles and limb position. We found that height had a significant effect on the DTM plane angles - the mean DTM plane angle was greater at the lower level compared to the mid and higher levels. A significant effect of shoulder orientation on mean DTM plane angles was shown in the sagittal and coronal planes. Our findings support the importance of training daily tasks at different heights during rehabilitation following wrist injuries, in order to explore a large range of DTM angles, to accommodate needs of common ADLs.     

注意线索对自闭特质个体疼痛共情的影响：来自事件相关电位的证据

自闭特质个体在日常生活中表现出共情缺损, 但其程度较自闭症谱系障碍个体低, 并且注意线索和特异性的面孔加工可能会影响他们的共情加工进程。因此, 本研究采用事件相关电位(ERP)技术, 以疼痛面孔图片作为刺激材料, 让自闭特质组和控制组分别完成疼痛判断任务(该任务中被试的注意指向疼痛线索)和吸引力判断任务(该任务中被试的注意不指向疼痛线索)。结果发现, 相比控制组, 自闭特质组在吸引力判断任务中疼痛面孔图片诱发的P3波幅更大, 而在疼痛判断任务中两组没有显著差异。这表明注意线索会影响自闭特质个体对他人疼痛面孔的共情反应, 当自闭特质个体不注意他人面孔的疼痛线索时, 其疼痛共情能力会减弱。     

Aggression,self-confidence,and cardiovascular reactions in competitive performance in adolescent boys

Interactions between suggested risk factors for the development of coronary heart disease (namely aggression, competitive performance, and cardiovascular reactions) were studied in 36 adolescent boys. Different manifestations of aggression were measured using a structured interview, the aggression-impatience factor of the MYTH test, and observation. Self-confidence was assessed by means of an interview. The performance tests used were the Stroop Color Word test and the P-factor test. Cardiovascular reactions were measured using an automatic noninvasive sphygmomanometer with a continuous recording system. Results showed that the significance of aggression in performance or competition cannot be evaluated separately; aggression in itself had an injurious effect on performance, but when combined with high self-confidence it resulted in a high level of performance. High cardiovascular reactivity was related to competitiveness rather than aggression. The results emphasize that before intervention programs for behavioral risk factors of coronary heart disease are planned, there are many questions to answer.     

Exploring goal taxonomies using the goal-based outcome tool in children and young people's mental health settings

Formulating goals in therapy may facilitate young people and parents/carers' engagement in mental health support settings. A number of goal taxonomies have been developed, which involve organising goals set at the outset of therapy into themes. Goal taxonomies are considered useful for service planning and outcome purposes. In order to build on the knowledge about what young people choose as goals, and to best support good practice, it is important to explore the links and differences between the existing goal taxonomies. A systematic review was conducted to identify goal taxonomies based on goals set using the goal-based outcome (GBO) tool. Framework analysis was conducted to investigate the extracted goal taxonomies. Overall, four core concepts were identified: “Goals targeting specific issues, symptoms, emotions, and behaviours,” “Return and engage in activities,” “Personal growth goals” and “Interpersonal goals.” Goals regarding specific issues, personal growth and interpersonal relationships were present in most studies. Using these overarching core concepts could be useful for practitioner-level, or service-level organisation of goal data, for activities such as service planning and delivery.
