The Clinical Case as a Basis for Research in Fundamental Psychopathology

(The Clinical Case as a Basis for Research in Fundamental Psychopathology) This article discusses aspects that hinder the process of drawing up clinical cases and stresses their importance for research in fundamental psychopathology. The author bases her thinking on several texts by Freud and his followers about the technique and the interpretation of dreams. In these texts, clinical cases are used to express a problem that must be investigated. The grounds for research follow the same logic as that used for interpreting dreams.

A DEVELOPMENTAL PERSPECTIVE OF INTERMANUAL PERFORMANCE ASYMMETRY IN AIMING

This study compared intermanual performance asymmetry between adults and children of different ages in timing components of an aiming task. Participants manipulated a computer mouse with either hand, aiming to rapidly reach targets of different widths with a pointer on a monitor. Results showed longer deceleration movements with the left hand in children, leading to increased intermanual performance asymmetry when aiming at narrower targets. Increased intermanual performance asymmetry in children is conceptualized to derive from planning to minimize trajectory variability when controlling the nondominant hand.

Clinical Efficacy of a New Automated Hemoencefalographic Neurofeedback Protocol

Among the ongoing attempts to enhance cognitive performance, an emergent and yet underrepresented venue is brought by hemoencefalographic neurofeedback (HEG). This paper presents three related advances in HEG neurofeedback for cognitive enhancement: a) a new HEG protocol for cognitive enhancement, as well as b) the results of independent measures of biological efficacy (EEG brain maps) extracted in three phases, during a one year follow up case study; c) the results of the first controlled clinical trial of HEG, designed to assess the efficacy of the technique for cognitive enhancement of an adult and neurologically intact population. The new protocol was developed in the environment of a software that organizes digital signal algorithms in a flowchart format. Brain maps were produced through 10 brain recordings. The clinical trial used a working memory test as its independent measure of achievement. The main conclusion of this study is that the technique appears to be clinically promising. Approaches to cognitive performance from a metabolic viewpoint should be explored further. However, it is particularly important to note that, to our knowledge, this is the world's first controlled clinical study on the matter and it is still early for an ultimate evaluation of the technique.
