Bodily expressions,feelings, and the direct perception account of social cognition

Phenomenology and the Cognitive Sciences - In this paper, I will argue in favor of a direct perception account of social cognition (DP), focusing on the idea that we can directly grasp at least...     

Newborns’ preference for up–down asymmetrical configurations

The present study was aimed at investigating whether, because of a differential sensitivity between the upper and the lower visual fields, in a visual preference task newborns would orient more frequently and look longer at patterns with a great number of high–contrast areas in the upper or lower visual field. Newborns were presented with three pairs of geometrical stimuli, each composed of a pattern with a greater number of elements in the upper part or a pattern with more elements in the lower part. The results showed a reliable preference for the stimuli that had more elements in the upper than in the lower part. The evidence obtained suggests the possibility that, at birth, the visibility of a stimulus depends not only on its sensory properties, but also on its structural characteristics.     

The abundance effect: Unethical behavior in the presence of wealth

Three laboratory studies investigated the hypothesis that the presence of wealth may influence people’s propensity to engage in unethical behavior for financial gain. In the experiments, participants were given the opportunity to cheat by overstating their performance on an anagram task. In each study, one group was stimulated by the visible proximity of monetary wealth. We found that the presence of abundant wealth led to more frequent cheating than an environment of scarcity. Our experiments also investigated the potential mechanisms behind this effect. The results showed that the presence of abundant wealth provoked feelings of envy toward wealthy others that, in turn, led to unethical behavior. Our findings offer insights into when and why people engage in unethical behavior.     

Affective interactions using virtual reality: the link between presence and emotions.

Many studies showed the ability of movies and imagery techniques to elicit emotions. Nevertheless, it is less clear how to manipulate the content of interactive media to induce specific emotional responses. In particular, this is true for the emerging medium virtual reality (VR), whose main feature is the ability to induce a feeling of "presence" in the computer-generated world experienced by the user. The main goal of this study was to analyze the possible use of VR as an affective medium. Within this general goal, the study also analyzed the relationship between presence and emotions. The results confirmed the efficacy of VR as affective medium: the interaction with "anxious" and "relaxing" virtual environments produced anxiety and relaxation. The data also showed a circular interaction between presence and emotions: on one side, the feeling of presence was greater in the "emotional" environments; on the other side, the emotional state was influenced by the level of presence. The significance of these results for the assessment of affective interaction is discussed.     

Persistence of Traumatic Symptoms After Seven Years: Evidence from Young Individuals Exposed to the L’Aquila Earthquake

In this article, we investigated the presence of trauma-induced sequelae in a sample of 41 young individuals exposed to the L’Aquila earthquake who did not seek mental help in the aftermath of the disaster or in the ensuing months. We compared this group with 43 individuals, matched for age and education, who had not experienced an earthquake but had moved to and lived in L’Aquila after the earthquake and thus experienced the challenges of living in an earthquake-struck city. This study aimed to show that earthquake-exposed individuals scored significantly higher than nonexposed persons on certain scales of the Trauma Symptom Inventory (TSI) seven years after the event. Our results indicated that exposed individuals exhibited higher scores on the dissociation, intrusive experience, and defensive avoidance scales. Furthermore, a correlational analysis between specific conditions detected by the Earthquake Checklist L’Aquila (ECLA) and the TSI identified the influences of specific conditions, such as being trapped or injured under rubble during the earthquake, experiencing a persistent fear of aftershocks or a life-threatening feeling, and witnessing the death of a loved one. All of these experiences resulted in the persistence of trauma-related symptoms. Dissociative experiences during the trauma, cognitive and behavioral avoidance and reexperiencing were associated with negative effects and may hinder the natural process of recovery in trauma-exposed individuals. Knowledge of mid- and long-term psychological difficulties following a traumatic event may be useful for promoting interventions in mental health across exposed populations.     

Enhanced perceptual processing of speech in autism

Theories of autism have proposed that a bias towards low-level perceptual information, or a featural/surface-biased information-processing style, may compromise higher-level language processing in such individuals. Two experiments, utilizing linguistic stimuli with competing low-level/perceptual and high-level/semantic information, tested processing biases in children with autism and matched controls. Whereas children with autism exhibited superior perceptual processing of speech relative to controls, and showed no evidence of either a perceptual or semantic processing bias, controls showed a tendency to process speech semantically. The data provide partial support to the perceptual theories of autism. It is additionally proposed that the pattern of results may reflect different patterns of attentional focusing towards single or multiple stimulus cues in speech between children with autism and controls.     

Assessing the impact of replication on implicit association test effect by means of the extended logistic model for the assessment of change

The present study consists of a longitudinal investigation in which implicit association measures were collected by means of the implicit association test (IAT), with the purpose of assessing the impact of replication on the test effect with the same participants. The extended logistic model for the assessment of change (ELMAC), a procedure that belongs to Rasch modeling, was applied. By means of the ELMAC application, the existence of latent traits characteristic of the impact on the IAT effect (due to replication through time) is shown; more precisely, the model time parameters show the decrement of the IAT effect through time, due to the decrease of the implicit preference in both conditions, compatible and incompatible, associated with sweet foods and salty foods. The results confirm that in the long run, the incompatible condition latency may approach the compatible condition latency, causing a significant attenuation of the IAT effect.     

The power of the positive: revisiting weak coherence in autism spectrum disorders

This paper reexamines Frith's original concept of weak coherence, its historical origins, recent reformulations, and alternative accounts. We suggest that the key notion of reduced global integration of information, which Frith proposed to underlie the assets in local processing, has been neglected in recent accounts of autism spectrum disorders (ASD). In fact, most paradigms used to test weak coherence conflate global and local processing, often placing them in direct trade-off, so that it is not possible to tell whether patterns of performance in ASD reflect reduced global processing, increased local processing, or both. We review the literature from typical development and ASD that may be pertinent to this distinction and examine some data from our own studies. Only once tasks are devised that measure separately the effects of reduced global processing and increased local processing will it be possible to test the on-line and developmental relations between these two aspects of "weak coherence". Some preliminary ideas about these relationships are discussed, and suggestions are made for why disentangling two possibly independent dimensions of weak coherence may be timely and productive.
