Should inter-collegiate football be eliminated? Assessing the arguments philosophically

Recently, there have been discussions about whether or not inter-collegiate football should be eliminated in the US. This article philosophically assesses the arguments for its elimination as well as the arguments proffered against its elimination. While a variety of arguments are discussed, a new one is brought into the foray of philosophical investigation, one that combines the unfairness and economic arguments: the health care and medical costs to others argument. It is believed that this argument is sufficient to justify the elimination of inter-collegiate football.     

Istituto Erich Fromm di Psicoanalisi Neofreudiana: Report on how the Institute has taken up Fromm's psychoanalytic teachings and on the terms in which it conceives Fromm's contribution to psychoanalysis

The Institute intends to contribute to the formation of a Frommian research tradition and to its development in Italy. During his lifetime Fromm carried out a daily clinical work on which he based all his theories. The Institute is interested in collecting this wealth of clinical experience through study and research. On the subject of technique, written and recorded documents consist of valuable notes, which are found in various books, and of posthumous works and recorded seminars and interviews. After a brief historical note on the Institute, the Frommian perspective is presented at length with a view to understanding how psychoanalysis reacts to the radical humanism. Emphasis is placed on the idea that Fromm's thought orientation is not an organised school of psychoanalysis but an open and critical contribution. This view offers an explanation of Fromm's abstention to codify a psychoanalytic technique to be applied in a standardised way. Although this report regards above all the clinical psychoanalysis, we must remember great thinkers such as Meister Eckhart and Spinoza, who inspired Fromm's perspective and gave strength to it.     

The role of attachment to God in secular and religious/spiritual ways of coping with a serious disease

This study investigated the role of security in one's attachment to God in relation to both secular and religious/spiritual ways of coping with a serious illness. The main objective was to test whether attachment to God and type of disease were related to secular coping strategies, when controlling for the effects of religious/spiritual coping. Study participants (N = 105) had been diagnosed either with cancer (i.e., an acute disease) and were under chemotherapy/awaiting surgery or with renal impairment (i.e., a chronic disease) and were attending dialysis. Results showed that secure attachment to God was uniquely related to fighting spirit, whereas insecure attachment to God was uniquely linked to hopelessness, suggesting that security, unlike insecurity, in one's attachment to God may impact favourably on adjustment to the disease. The only coping strategy related to type of disease was cognitive avoidance, which was linked to chronic disease.     

How affordances associated with a distractor object affect compatibility effects: A study with the computational model TRoPICALS

Seeing an object activates both visual and action codes in the brain. Crucial evidence supporting this view is the observation of object to response compatibility effects: perception of an object can facilitate or interfere with the execution of an action (e.g., grasping) even when the viewer has no intention of interacting with the object. TRoPICALS is a computational model that proposes some general principles about the brain mechanisms underlying compatibility effects, in particular the idea that top-down bias from prefrontal cortex, and whether it conflicts or not with the actions afforded by an object, plays a key role in such phenomena. Experiments on compatibility effects using a target and a distractor object show the usual positive compatibility effect of the target, but also an interesting negative compatibility effect of the distractor: responding with a grip compatible with the distractor size produces slower reaction times than the incompatible case. Here, we present an enhanced version of TRoPICALS that reproduces and explains these new results. This explanation is based on the idea that the prefrontal cortex plays a double role in its top-down guidance of action selection producing: (a) a positive bias in favour of the action requested by the experimental task; (b) a negative bias directed to inhibiting the action evoked by the distractor. The model also provides testable predictions on the possible consequences of damage to volitional circuits such as in Parkinsonian patients.     

The processing of verbs and nouns in neural networks: insights from synthetic brain imaging

The paper presents a computational model of language in which linguistic abilities evolve in organisms that interact with an environment. Each individual's behavior is controlled by a neural network and we study the consequences in the network's internal functional organization of learning to process different classes of words. Agents are selected for reproduction according to their ability to manipulate objects and to understand nouns (objects' names) and verbs (manipulation tasks). The weights of the agents' neural networks are evolved using a genetic algorithm. Synthetic brain imaging techniques are then used to examine the functional organization of the neural networks. Results show that nouns produce more integrated neural activity in the sensory-processing hidden layer, while verbs produce more integrated synaptic activity in the layer where sensory information is integrated with proprioceptive input. Such findings are qualitatively compared with human brain imaging data that indicate that nouns activate more the posterior areas of the brain related to sensory and associative processing, while verbs activate more the anterior motor areas.     

Task demand effects on postural control in older adults

The literature shows conflicting results regarding older adults' (OA) postural control performance. Differing task demands amongst scientific studies may contribute to such ambiguous results. Therefore, the purpose of this study was to examine the performance of postural control in older adults and the relationship between visual information and body sway as a function of task demands. Old and young adults (YA) maintained an upright stance on different bases of support (normal, tandem and reduced), both with and without vision, and both with and without room movement. In the more demanding tasks, the older adults displayed greater body sway than the younger adults and older adults were more influenced by the manipulation of the visual information due to the room movement. However, in the normal support condition, the influence of the moving room was similar for the two groups. These results suggest that task demand is an important aspect to consider when examining postural control in older adults.     

Seeing your own touched hands in a mirror modulates cross-modal interactions

In mirror reflections, visual stimuli in near peripersonal space (e.g., an object in the hand) can project the retinal image of far, extrapersonal stimuli "beyond" the mirror. We studied the interaction of such visual reflections with tactile stimuli in a cross-modal congruency task. We found that visual distractors produce stronger interference on tactile judgments when placed close to the stimulated hand, but observed indirectly as distant mirror reflections, than when directly observed in equivalently distant far space, even when in contact with a dummy hand or someone else's hand in the far location. The stronger visual-tactile interference for the mirror condition implies that near stimuli seen as distant reflections in a mirror view of one's own hands can activate neural networks coding peripersonal space, because these visual stimuli are coded as having a true source near to the body.     

Tool-use changes multimodal spatial interactions between vision and touch in normal humans

In a visual-tactile interference paradigm, subjects judged whether tactile vibrations arose on a finger or thumb (upper vs. lower locations), while ignoring distant visual distractor lights that also appeared in upper or lower locations. Incongruent visual distractors (e.g. a lower light combined with upper touch) disrupt such tactile judgements, particularly when appearing near the tactile stimulus (e.g. on the same side of space as the stimulated hand). Here we show that actively wielding tools can change this pattern of crossmodal interference. When such tools were held in crossed positions (connecting the left hand to the right visual field, and vice-versa), the spatial constraints on crossmodal interference reversed, so that visual distractors in the other visual field now disrupted tactile judgements most for a particular hand. This phenomenon depended on active tool-use, developing with increased experience in using the tool. We relate these results to recent physiological and neuropsychological findings.
