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.     

The triadic legitimacy model: Understanding support to disobedient groups

In a social-psychological perspective, many scholars have argued that disobedience plays a significant role in avoiding the degeneration of the authority into autocracy and in promoting social change. In particular, the tripolar model (minority-majority-population) proposed by Mugny (1982) emphasized the role of the population for the stability or the progress of every society. Authority may indeed preserve the status quo only on the grounds of its influence on a large population. Likewise, protesters may achieve social change only by influencing and involving a large part of the population in their struggles. In understanding why people decide to join a protest, the aim of this article is to integrate Kelman and Hamilton's (1989) analysis of legitimacy with the tripolar model on social influence. The model we propose – namely the triadic legitimacy model (TLM) – explains the dialectic between social stability and social change by considering both authority's and disobedient groups' legitimacies.     

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.     

Correction of a Technical Error in the Golf Swing: Error Amplification Versus Direct Instruction

Performance errors drive motor learning for many tasks. The authors' aim was to determine which of two strategies, method of amplification of error (MAE) or direct instruction (DI), would be more beneficial for error correction during a full golfing swing with a driver. Thirty-four golfers were randomly assigned to one of three training conditions (MAE, DI, and control). Participants were tested in a practice session in which each golfer performed 7 pretraining trials, 6 training-intervention trials, and 7 posttraining trials; and a retention test after 1 week. An optoeletronic motion capture system was used to measure the kinematic parameters of each golfer's performance. Results showed that MAE is an effective strategy for correcting the technical errors leading to a rapid improvement in performance. These findings could have practical implications for sport psychology and physical education because, while practice is obviously necessary for improving learning, the efficacy of the learning process is essential in enhancing learners' motivation and sport enjoyment.     

Ambiguous emotion recognition in temporal lobe epilepsy: The role of expression intensity

The lateralization of emotion processing is currently debated and may be further explored by examining facial expression recognition (FER) impairments in temporal lobe epilepsy (TLE). Furthermore, there is also debate in the literature whether FER deficits in individuals with TLE are more pronounced in the right than in the left hemisphere. Individuals with TLE were tested with an FER task designed to be more sensitive than those classically used to shed light on this issue. A total of 25 right- and 32 left-TLE patients, candidates for surgery, along with controls, underwent an FER task composed of stimuli shown not only at full-blown intensities (100 %), but also morphed to lower-intensity display levels (35 %, 50 %, and 75 %). The results showed that, as compared to controls, right-TLE patients showed deficits in the recognition of all emotional categories. Furthermore, when considering valence, right-TLE patients were impaired only in negative emotion recognition, but no deficits for positive emotions were highlighted in left-TLE patients. Finally, only the right-TLE patients’ impairment was found to be related to the age of epilepsy onset. Our work demonstrates that the FER deficits in TLE span multiple emotional categories and show manifestations dependent on the laterality of the epileptic focus. Taken together, our findings provide the strongest evidence for the right-hemisphere model, but they also partially support the valence model. We suggest that current models are not exhaustive at explaining emotional-processing cerebral control, and further that multistep models should be developed.     

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.     

Life Satisfaction and Cannabis Use: A Study on Young Adults

Cannabis is the illicit substance most used by young adults and adolescents in rich nations. Cannabis use may have negative consequences on mental and physical health and has been associated with low wellbeing indexes (i.e., life satisfaction). The present study aims to investigate the relationship of life satisfaction with cannabis use in young adults compared with personality and sociodemographic variables. Previous studies have found relationships between the Big Five traits and cannabis use as well as a gender gap. Males have been shown to have a higher consumption of cannabis than females. We conducted a survey by means of a self-report questionnaire on a sample of 600 young adults (average age 22.20 years) and performed a regression analysis to test the relationships of sociodemographic variables, personality, and life satisfaction with cannabis use. The results confirmed the gender gap and showed an association between cannabis use and conscientiousness, agreeableness, openness and life satisfaction. Life satisfaction was negatively related to cannabis use, which suggests that this behaviour may be motivated by coping with unsatisfactory life conditions.
