Abstract

We rely heavily on faces during social interactions. Humans possess the ability to recognise thousands of people very quickly and accurately without effort. The serious social difficulties that follow abnormalities of the face recognition system (i.e., prosopagnosia) strongly underline the importance of typical face skills in our everyday life. Over the last fifty years, research on prosopagnosia, along with research in the healthy population, has provided insights into the cognitive and neural features behind typical face recognition. This has also been achieved thanks to non-invasive neuroimaging techniques such as functional Magnetic Resonance Imaging (fMRI), Electroencephalography (EEG), Magnetoencephalography (MEG), Diffusion Tensor Imaging (DTI) and Transcranial Magnetic Stimulation (TMS). However, there is still much debate about the cognitive and neural mechanisms of face perception. In the current Research Topic we plan to gather experimental works, opinions, commentaries, mini-reviews and reviews that focus on new or novel theories and methods in face perception research. Where is the field at the moment? Do we need to re-think the experimental procedures we have adopted so far? Again, what kind of techniques (or combination of them) and analysis methods will be important in the future? From the experimental point of view we encourage both behavioural and neuroimaging contributions (e.g., fMRI, EEG, MEG, DTI and TMS). Despite the main emphasis on face perception, memory and identification, we will also consider original works that focus on other aspects of face processing, such as expression recognition, attractiveness judgments and face imagery. In addition, animal investigations and experimental manipulations that alter face recognition abilities in typical human subjects (e.g., hypnosis) are also welcome. Overall, we are proposing a Research Topic that looks at face processing using different perspectives and welcome contributions from different domains such as psychology, neurology, neuroscience, cognitive science and philosophy. The current Research Topic evolved over the desire to acknowledge the relatively recent loss of three giants in the field: Drs. Shlomo Bentin, Truett Allison and Andy Calder. We dedicate this Research Topic to them and their pioneering studies.

Abstract

Psychomotor symptoms are those symptoms that are characterized by deficits in the initiation, execution and monitoring of movements, such as psychomotor slowing, catatonia, neurological soft signs (NSS), reduction in motor activity or extrapyramidal symptoms (EPS). These symptoms have not always received the attention they deserve although they can be observed in a wide range of psychiatric illnesses, including mood disorders, psychotic disorders, anxiety disorders, pervasive developmental disorders and personality disorders. Nevertheless, these symptoms seem to have prognostic value on clinical and functional outcome in several pathologies. In the late 19th century, the founding fathers of modern psychiatry (including Kahlbaum, Wernicke, Kraepelin and Bleuler) had a strong focus on psychomotor abnormalities in their description and definitions of psychiatric illnesses and systematically recognized these as core features of several psychiatric pathologies. Nevertheless, emphasis on these symptoms has reduced substantially since the emergence of psychopharmacology, given the association between antipsychotics or antidepressants and medication-induced motor deficits. This has resulted in the general idea that most if not all psychomotor deficits were merely side effects of their treatment rather than intrinsic features of the illness. Yet, the last two decades a renewed interest in these deficits can be observed and has yielded an exponential growth of research into these psychomotor symptoms in several psychiatric illnesses. This recent evolution is also reflected in the increased appreciation of these symptoms in the DSM-5. As a result of this increased focus, new insights into the clinical and demographical presentation, the etiology, the course, the prognostic value as well as treatment aspects of psychomotor symptomatology in different illnesses has emerged. Still, many new questions arise from these findings. This research topic is comprised of all types of contributions (original research, reviews, and opinion piece) with a focus on psychomotor symptomatology in a psychiatric illness, especially research focusing on one or more of the following topics: the clinical presentation of the psychomotor syndrome; the course through the illness; the diagnostical specificity of the syndrome; the underlying neurobiological or neuropsychological processes; new assessment techniques; pharmacological or non-pharmacological treatment strategies.

Abstract

Le trouble déficitaire de l’attention avec ou sans hyperactivité est lié étroitement aux fonctions exécutives. En effet, aussi bien dans le modèle de Barkley (1997) pour le TDAH que dans celui de Diamond (2013) pour les fonctions exécutives, l’inhibition est un point central. Elle correspond non seulement à une des fonctions exécutives mais aussi à ce qui est déficitaire chez les personnes atteintes d’un TDAH.&#13;Le langage intérieur, selon Vygotsky (1934), est une sorte de langage avec soi-même qui est notamment utilisé lors la résolution de tâches complexes impliquant les fonctions exécutives. Ce langage, Barkley en parle dans sa modélisation du TDAH en disant que chez les personnes ayant ce trouble, son intériorisation serait différée.&#13;Quel impact a donc le trouble déficitaire de l’attention sur l’utilisation du langage intérieur ? C’est la question qui a guidé les recherches menées dans le cadre de ce mémoire. Pour tester cela, il a fallu recruter 10 enfants séparés en deux groupes. Un groupe contrôle et un autre composé d’enfants TDAH. Ces sujets âgés de 7 à 10 ans ont dû passer des tests impliquant les fonctions exécutives. Le testing s’est déroulé sous deux conditions. Une condition contrôle et une condition de suppression articulatoire obligeant l’enfant à utiliser son langage intérieur. Une fois les séances terminées, des comparaisons intra et intergroupes ont été réalisées.&#13;Après avoir analysé statistiquement les données obtenues, peu de résultats se sont montrés significatifs. Du côté du groupe contrôle, les hypothèses allaient dans ce sens. Par contre, du côté du groupe TDAH nous nous attendions à plus de significativité des résultats. Cela aurait pu prouver une difficulté ou un retard dans l’utilisation/l’acquisition du langage intérieur dû au trouble.&#13;Pour expliquer ces résultats, plusieurs réflexions ont fait surface. La principale se rapporte à la taille réduite de l’échantillon qui le rendrait non représentatif de la population.

Abstract

The last forty years of research have demonstrated that working memory (WM) is a key concept for understanding higher-order cognition. To give an example, WM is involved in reading comprehension, problem solving and reasoning, but also in a number of everyday life activities. It has a clear role in the case of atypical development too. For instance, numerous studies have shown an impairment in WM in individuals with learning disabilities (LD) or intellectual disabilities (ID); and several researchers have hypothesized that this can be linked to their difficulties in learning, cognition and everyday life. The latest challenge in the field concerns the trainability of WM. If it is a construct central to our understanding of cognition in typical and atypical development, then specific intervention to sustain WM performance might also promote changes in cognitive processes associated with WM. The idea that WM can be modified is debated, however, partly because of the theoretical implications of this view, and partly due to the generally contradictory results obtained so far. In fact, most studies converge in demonstrating specific effects of WM training, i.e. improvements in the trained tasks, but few transfer effects to allied cognitive processes are generally reported. It is worth noting that any maintenance effects (when investigated) are even more meagre. In addition, a number of methodological concerns have been raised in relation to the use of: 1. single tasks to assess the effects of a training program; 2. WM tasks differing from those used in the training to assess the effects of WM training; and 3. passive control groups. These and other crucial issues have so far prevented any conclusions from being drawn on the efficacy of WM training. Bearing in mind that the opportunity to train WM could have a huge impact in the educational and clinical settings, it seems fundamentally important to shed more light on the limits and potential of this line of research. The aim of the research discussed here is to generate new evidence on the feasibility of training WM in individuals with LD and ID. There are several questions that could be raised in this field. For a start, can WM be trained in this population? Are there some aspects of WM that can be trained more easily than others? Can a WM training reduce the impact of LD and ID on learning outcomes, and on everyday living? What kind of training program is best suited to the promotion of such changes?

Abstract

Neurofeedback is an operant learning procedure where participants learn to gain self-control over specific aspects of neural activity. Thus, depending on the neurofeedback protocol applied behavioural, cognitive and / or emotional effects can be induced. Different assumptions about mechanisms, moderators and mediators of neurofeedback exist, associated with different ways of application. EEG-based neurofeedback is used as a therapeutic approach in attention-deficit / hyperactivity disorder (ADHD), a clinically and pathophysiologically heterogeneous child psychiatric disorder. There is increasing evidence for specific effects of neurofeedback when applying 'standard' protocols (slow cortical potentials, theta/beta, SMR). Knowledge about underlying mechanisms and moderating variables is increasing. Nevertheless, further well-controlled and conducted trials are needed to answer open questions concerning optimisation and individualisation of neurofeedback training. Further improvements may be expected from new methodical and technical developments (e.g., tomographic neurofeedback) and new concepts (integrated ADHD treatment). The Frontiers Research Topic intends to provide answers to the following questions concerning neurofeedback in ADHD: How efficacious is neurofeedback / does a certain neurofeedback protocol work? What is the rationale of applying a certain neurofeedback protocol in ADHD? What are central mechanisms and which moderating variables may affect training outcome? How to optimise treatment? What are new developments and which benefits may be expected?

Abstract

Although the phenomenon of ADHD (Attention-Deficit Hyperactivity Disorder) is well described in children, it is now thought that in up to 60% of cases the symptoms persist into adulthood. This volume reviews our growing knowledge of adult ADHD and presents a transatlantic perspective on the identification, assessment and treatment of the disorder. The introductory section covers the history of ADHD, as well as the epidemiology, consequences, gender differences and legal aspects. Detailed descriptions of the clinical features of ADHD in adults are then given to enhance the reader's clinical recognition and assessment. Subsequent sections cover treatment strategies, emphasising pharmacological, psychological and social interventions. Written and edited by experts internationally renowned for their work in ADHD, this is an essential resource for all mental health workers who encounter adults presenting with neurodevelopmental disorders.

Abstract

The treatment of Attention Deficit Hyperactivity Disorder is a matter of ongoing research and debate, with considerable data supporting both psychopharmacological and behavioral approaches. Researchers continue to search for new interventions to be used in conjunction with or in place of the more traditional approaches. These interventions run the gamut from social skills training to cognitive behavioral interventions to meditation to neuropsychologically-based techniques. The goal of this volume is to explore the state-of-the-art in considerations in the treatment of ADHD around the world. This broad survey covers issues related to comorbidity that affect the treatment choices that are made, the effects of psychopharmacology, and non-medication treatments, with a special section devoted to the controversial new treatment, neurofeedback. There is something in this volume for everyone interested in the treatment of ADHD, from students examining the topic for the first time to researchers and practitioners looking for inspiration for new research questions or potential interventions.
