Abstract

Empathy and psychopathy seem to be two distant extremes, which only differ, with nothing similar. Therefore, the question that seems to be surprising is whether such a theoretical perspective is justified. Empathy exerts significant influence on social relationships and is associated with moral development, whereas psychopathy seems to be an opposite phenomenon, as it is associated with the lack of deep interpersonal bonds and the violation of legal norms. As studies from various disciplines and scientific areas indicate, such concepts as behavioral effectiveness, morality or altruism might help explain the complex nature of the interrelationship between psychopathy and empathy. The authors tried to explore and describe the complexity of the two presented concepts in the light of the conducted research, and the resulting theoretical and empirical implications.

Abstract

Introduction: Arthrocentesis has been used in the temporomandibular joint (TMJ) to analyze components of the synovial fluid or as a therapeutic procedure associated or not with the admini- stration of a drug. The rabbit is one of the most commonly used animal species as a model for pathologies that affect the TMJ. The aim of this study was to propose a specific technique to perform arthrocentesis on the rabbit TMJ, emphasizing descriptions of reference points and measurements for a successful puncture without complications. Materials and methods: Fourteen adult rabbits (Oryctolagus cuniculus) were used. The project was approved by the Scientific Ethics Committee of the Universidad de La Frontera (File Nº083/2016). Results: The description of the technique was divided into three steps: 1) Location of the rabbit TMJ, 2) Positioning of the needles in the TMJ, and 3) Passage of fluid through the TMJ. Conclusions: This arthrocen- tesis technique could help to simplify the procedure and give the investigator a guide for joint washing and extraction of synovial fluid in the rabbit TMJ.

Abstract

Speech and music signals are multifractal phenomena. The time displacement profile of speech and music signal show strikingly different scaling behaviour. However, a full complexity analysis of their frequency and amplitude has not been made so far. We propose a novel complex network based approach (Visibility Graph) to study the scaling behaviour of frequency wise amplitude variation of speech and music signals over time and then extract their PSVG (Power of Scale freeness of Visibility Graph). From this analysis it emerges that the scaling behaviour of amplitude-profile of music varies a lot from frequency to frequency whereas it’s almost consistent for the speech signal. Our left auditory cortical areas are proposed to be neurocognitively specialised in speech perception and right ones in music. Hence we can conclude that human brain might have adapted to the distinctly different scaling behaviour of speech and music signals and developed different decoding mechanisms, as if following the so called Fractal Darwinism. Using this method, we can capture all non-stationary aspects of the acoustic properties of the source signal to the deepest level, which has huge neurocognitive significance. Further, we propose a novel non-invasive application to detect neurological illness (here autism spectrum disorder, ASD), using the quantitative parameters deduced from the variation of scaling behaviour for speech and music.

Abstract

The text discusses the problems of sensory processing disorders (SPD) and their impact on difficulties children have at school. Individual categories of sensory processing disorders were characterized and examples of behavior of children who may have those problems were described. Certain strategies which teachers can use when working with a child with SI disorders were also offered. It should be noted that the early diagnosis of symptoms that may indicate the occurrence of sensory processing disorders, followed by apt diagnosis and therapy allow children to function properly in the school environment and positively influence their self-esteem. This in turn facilitates the process of learning and contributes future success.

Abstract

The persons with intellectual disability have serious difficulties in language skills and consequently in the process of learning. The problems can be caused by Central Auditory Processing Disorders. In this paper we present research results on effectiveness of the Warnke method as a supporting tool in the development of language skills and in the process of education of children with such intellectual disabilities of mild degree.
