Ideomotor silence: the case of complete paralysis and brain–computer interfaces (BCI)

The paper presents some speculations on the loss of voluntary responses and operant learning in long-term paralysis in human patients and curarized rats. Based on a reformulation of the ideomotor thinking hypothesis already described in the 19th century, we present evidence that instrumentally learned responses and intentional cognitive processes extinguish as a consequence of long-term complete paralysis in patients with amyotrophic lateral sclerosis (ALS). Preliminary data collected with ALS patients during extended and complete paralysis suggest semantic classical conditioning of brain activity as the only remaining communication possibility in those states.     

The role of children’s negative attributions on depressive symptoms: an inherited characteristic or a product of the early environment?

Negative attributional style has been associated with depressive symptoms in children. Yet, it is unclear whether these cognitive biases reflect inherited characteristics of the broader depressive phenotype or are a product of children's environments. While existing data in adolescents show that negative attributions reflect a genetic predisposition, elevating depressive responses to stress, other data suggest that negative attributions in children are more likely to reflect early environmental experiences on symptoms. Here, we assess the degree to which negative attributional style and depressive symptoms arise from common genetic, shared and non-shared environmental influences in childhood. Monozygotic and dizygotic twins reported on attributional style and depressive symptoms at age 8 (n = 300 pairs) and at age 10 (n = 250 pairs). Two multivariate models with varying assumptions on the nature of the relationship between negative attributions and depressive symptoms within and across time were fit to the data. The Common Pathway model provided better fit than the Cholesky decomposition. A common, latent factor influenced both attributional style and depressive symptoms at both time-points in children. The only significant influences on this factor were shared and non-shared aspects of the environment. Placing the present findings with those of adolescents suggests possible developmental differences in the relationship between attributional style and depressive symptoms.     

Resilience in adolescence: Gender differences two years after the earthquake of L’Aquila

The aim of this study was to evaluate the impact of L’Aquila earthquake (Italy) on Resilience and Coping 2 years after the earthquake in a high school sample. Three hundred and twenty-four male and female students exposed to the earthquake and 147 not-exposed have been assessed with the Resilience Scale for Adolescents (READ) and the Brief COPE. The two way ANOVAs for gender by exposure level to the distressing event showed statistically significant interactions with males exposed to the earthquake reporting consistently higher READ factor scores. Problem-focused but not emotion-focused coping strategies showed a similar pattern. These findings are compatible with a resilient ‘protective mechanism’ for males.     

The transformation of intercorporeality in melancholia

In this article the author seeks to highlight a specific disorder related to bodily experience in melancholia conceived as a severe form of clinical depression. The article is divided into three parts. In the first section, the author investigates the intersubjective dimension of bodily experience in light of the categories of Außen- and Innenleiblichkeit. In the second section, I explore a specific disturbance of the dimension of intercorporeality. The excessive feeling of the bodily (außenleibliche) visibility of his/her own sufferance is a fundamental aspect of depression. At a pre-reflexive level, we constantly assume the noncoincidence between one's own bodily expression and the Other's experience/reading of these expressions. An alteration of this (pre-reflexive) awareness occurs in melancholia. The patient feels as if the melancholic condition would be transparent to the other. In the third section, the author intends to show the alteration of the embodied communication between the melancholic person and the other investigating two particular phenomena: the exchange of gaze in a face to face encounter, and the disturbance of the oral sense, revealing a specific form of irresponsiveness and the experience of void.     

nodeGame: Real-time,synchronous, online experiments in the browser

nodeGame is a free, open-source JavaScript/ HTML5 framework for conducting synchronous experiments online and in the lab directly in the browser window. It is specifically designed to support behavioral research along three dimensions: (i) larger group sizes, (ii) real-time (but also discrete time) experiments, and (iii) batches of simultaneous experiments. nodeGame has a modular source code, and defines an API (application programming interface) through which experimenters can create new strategic environments and configure the platform. With zero-install, nodeGame can run on a great variety of devices, from desktop computers to laptops, smartphones, and tablets. The current version of the software is 3.0, and extensive documentation is available on the wiki pages at http://nodegame.org.

The evolution of alexia in two cases of posterior cortical atrophy

Posterior cortical atrophy (PCA) is an uncommon presentation of Alzheimer's disease (AD), characterised by prevalent anatomo-functional involvement of posterior cortical areas. Accordingly, the main clinical features at onset are disorders of high-order visual processing, such as alexia and impairments of visuo-spatial and visuo-constructional abilities. The clinical features in the early stages of disease are variable, and they have been suggested to stem from prevalent ventral or dorsal brain pathology, and/or asymmetric hemispheric involvement. With disease progression, these differences tend to blur with the increasing severity of neuropsychological dysfunction. We report two PCA patients showing different patterns of reading impairment (respectively, letter-by-letter reading and neglect dyslexia). A follow-up study suggested that the qualitative features of alexia remain distinctive with disease evolution. In addition, single photon emission tomography (SPECT) studies revealed different patterns of hypoperfusion, consistent with the alexia types. A careful reading assessment can provide important insights to the pattern of progression of the disease in patients with PCA up to the late stages of the pathology.     

Extraversion and accuracy of aspects of memory for pain in the cold water pressor test

The role of Erlebnistypus personality features were investigated in 40 healthy subjects, as defined by the Rorschach Comprehensive System by Exner, in determining accuracy in recollecting acute tonic experimental pain, induced by the Cold Water Pressor Test. Multiple-regression analysis revealed that the difference between the number of movement answers and the number of chromatic answers in the Rorschach test, an index of general Extroversion, predicted accuracy in recollecting the qualitative features of pain, defined as affective and evaluative pain scores on the McGill Pain Questionnaire. Also, Extratensive subjects were less accurate than Introversive and Ambitent participants at recollecting sensory scores. The data suggest that general extroversion may have a role in individual differences in the higher cognitive processing of pain comprising pain memory.     

Categorization by groups and individuals

Categorization is a core psychological process that is central to decision making. While a substantial amount of research has been conducted to examine individual categorization behavior, little is known about how the outputs of individual and group categorization may differ. Four experiments demonstrate that group categorization differs systematically from individual categorization in the structural dimension of category breadth: categorizing the same set of items, groups tend to create a larger number of smaller categories than individuals. This effect of social context is a function of both taskwork and teamwork. In terms of taskwork, groups’ greater available knowledge mediates differences in category breadth between individuals and groups by increasing utilized knowledge (study 2). In terms of teamwork, task conflict moderates the effect of social context on category breadth (study 3). Moreover, the experience of categorizing individually or in a group influences individuals’ subsequent judgments (study 4).
