The aim of this study was to investigate, using eye-tracking technique, the influence of bottom-up and top-down processes on visual behavior while subjects, naïve to art criticism, were presented with representational paintings. Forty-two subjects viewed color and black and white paintings (Color) categorized as dynamic or static (Dynamism) (bottom-up processes). Half of the images represented natural environments and half human subjects (Content); all stimuli were displayed under aesthetic and movement judgment conditions (Task) (top-down processes). Results on gazing behavior showed that content-related top-down processes prevailed over low-level visually-driven bottom-up processes when a human subject is represented in the painting. On the contrary, bottom-up processes, mediated by low-level visual features, particularly affected gazing behavior when looking at nature-content images. We discuss our results proposing a reconsideration of the definition of content-related top-down processes in accordance with the concept of embodied simulation in art perception.

This study explores the development of theory of mind, operationalized as recursive thinking ability, from adolescence to early adulthood (N= 110; young adolescents = 47; adolescents = 43; young adults = 20). The construct of theory of mind has been operationalized in two different ways: as the ability to recognize the correct mental state of a character, and as the ability to attribute the correct mental state in order to predict the character’s behaviour. The Imposing Memory Task, with five recursive thinking levels, and a third-order false-belief task with three recursive thinking levels (devised for this study) have been used. The relationship among working memory, executive functions, and linguistic skills are also analysed. Results show that subjects exhibit less understanding of elevated recursive thinking levels (third, fourth, and fifth) compared to the first and second levels. Working memory is correlated with total recursive thinking, whereas performance on the linguistic comprehension task is related to third level recursive thinking in both theory of mind tasks. An effect of age on third-order false-belief task performance was also found. A key finding of the present study is that the third-order false-belief task shows significant age differences in the application of recursive thinking that involves the prediction of others’ behaviour. In contrast, such an age effect is not observed in the Imposing Memory Task. These results may support the extension of the investigation of the third order false belief after childhood.

Movement perception and its role in aesthetic experience have been often studied, within empirical aesthetics, in relation to the human body. No such specificity has been defined in neuroimaging studies with respect to contents lacking a human form. The aim of this work was to explore, through functional magnetic imaging (fMRI), how perceived movement is processed during the aesthetic judgment of paintings using two types of content: human subjects and scenes of nature. Participants, untutored in the arts, were shown the stimuli and asked to make aesthetic judgments. Additionally, they were instructed to observe the paintings and to rate their perceived movement in separate blocks. Observation highlighted spontaneous processes associated with aesthetic experience, whereas movement judgment outlined activations specifically related to movement processing. The ratings recorded during aesthetic judgment revealed that nature scenes received higher scored than human content paintings. The imaging data showed similar activation, relative to baseline, for all stimuli in the three tasks, including activation of occipito-temporal areas, posterior parietal and premotor cortices. Contrast analyses within aesthetic judgment task showed that human content activated, relative to nature, precuneus, fusiform gyrus and posterior temporal areas, whose activation was prominent for dynamic human paintings. In contrast, nature scenes activated, relative to human stimuli, occipital and posterior parietal cortex/precuneus, involved in visuospatial exploration and pragmatic coding of movement, as well as central insula. Static nature paintings further activated, relative to dynamic nature stimuli, central and posterior insula. Besides insular activation, which was specific for aesthetic judgment, we found a large overlap in the activation pattern characterizing each stimulus dimension (content and dynamism) across observation, aesthetic judgment and movement judgment tasks. These findings support the idea that the aesthetic evaluation of artworks depicting both human subjects and nature scenes involves a motor component, and that the associated neural processes occur quite spontaneously in the viewer. Furthermore, considering the functional roles of posterior and central insula, we suggest that nature paintings may evoke aesthetic processes requiring an additional proprioceptive and sensori-motor component implemented by “motor accessibility” to the represented scenario, which is needed to judge the aesthetic value of the observed painting.

Background: Research on Theory of Mind (ToM), the ability to understand behaviour based on mental state representation, has shifted towards a life span perspective in typical and atypical conditions (dementia). Objectives: The aim of this study is to investigate the presence and the features of ToM decay in early Alzheimer's disease (AD) patients compared to healthy controls adopting a neurodevelopmental stance. Method: Sixteen AD patients and 16 healthy controls were submitted to an increasing complexity ToM battery, tapping ToM precursors, standard first- and second-order false beliefs and advanced ToM tasks (Eyes Test and strange stories). Results: The results underline a similar pattern of increasing difficulty of the tasks that explore ToM abilities in both the groups. They also confirm the presence of a strong gap in performance between the CTR and the AD groups, especially in the more complex ToM tasks, whereas there is no significant difference between the two groups in the first level of reasoning about beliefs (first-order false belief). The impairment in specific cognitive functions (i.e. memory and executive functions) seems to correlate with the decline in the most complex mentalistic abilities. Conclusion: This study identifies a specific pattern of deterioration in ToM abilities in AD patients, following backwards developmental steps typical of the acquisition of mentalizing abilities, where the most complex ToM levels are impaired, whereas the intermediate and the simplest ones are preserved.

Theory of Mind (ToM) undergoes changes at the behavioral level in pathological aging (Alzheimer's disease (AD)) and at the neural level in physiological aging. The aim was to determine if there are changes in ToM in the behavioral and neural domains in old subjects with high risk of switching from successful to unsuccessful neurocognitive aging. Patients with amnestic mild cognitive impairment (aMCI) syndrome were studied, since aMCI was proposed to fill the gap between normal aging and dementia. Sixteen aMCI patients (mean age 71 years) and fifteen healthy controls (mean age 67 years) with no differences in age or education were subjected to increasingly complex ToM tasks and to fMRI scanning while performing the Reading the Mind in the Eyes test (RME), which attributes mental states by focusing on eye-gaze. aMCI subjects had worse performances in two second order false belief tasks, confirming the decay of ToM on the behavioral level. Despite a minor activation of some components (posterior end of the superior temporal sulcus and temporal pole) of the ToM neural circuit, no significant differences in the behavioral performances to the RME was found in aMCI compared to controls. Probably the preservation of the mirror neuron system (precentral gyrus-BA 6; Broca area - BA 44) and the stronger involvement of frontal areas (middle and medial frontal cortex and anterior cingulate cortex) supplemented the decay of part of the mentalizing neural circuit, preserving task performance.
