    Age and Culture Effects on the Ability to Decode Affect Bursts

    No full text
    This paper investigates the ability of adolescents (aged 13–15 years) and young adults (aged 20–26 years) to decode affective bursts culturally situated in a different context (Francophone vs. South Italian). The effects of context show that Italian subjects perform poorly with respect to the Francophone ones revealing a significant native speaker advantage in decoding the selected affective bursts. In addition, adolescents perform better than young adults, particularly in the decoding and intensity ratings of affective bursts of happiness, pain, and pleasure suggesting an effect of age related to language expertise.Published1TM.

    On the Significance of Speech Pauses in Depressive Disorders: Results on Read and Spontaneous Narrative

    This paper investigates whether and how depressive disorders affect speech and in particular timing strategies for speech pauses (empty and filled pauses, as well as, phoneme lengthening). The investigation is made exploiting read and spontaneous narratives. The collected data are from 24 subjects, divided into two groups (depressed and control) asked to read a tale, as well as, spontaneously report on their daily activities. Ten different frequency and duration measures for pauses and clauses are proposed and have been collected using the PRAAT software on the speech recordings produced by the participants. A T-Student test for independent samples was applied on the collected frequency and duration measures in order to ascertain whether significant differences between healthy and depressed speech measures are observed. In the “spontaneous narrative” condition, depressed patients exhibited significant differences in: the average duration of their empty pauses, the average frequency, and the average duration of their clauses. In the read narratives, only the average pause’s frequency of the clauses was significantly lower in the depressed subjects with respect to the healthy ones. The results suggest that depressive disorders affect speech quality and speech production through pause and clause durations, as well as, clause quantities. In particular, the significant differences in clause quantities (observed both in the read and spontaneous narratives), suggest a strong general effect of depressive symptoms on cognitive and psychomotor functions. Depressive symptoms produce changes in the planned timing of pauses, even when reading, modifying the timing of pausing strategies

    Exploring the Relationship Between Attention and Awareness. Neurophenomenology of the Centroencephalic Space of Functional Integration

    Although there is a no established theory, there is no longer any doubt about the multiplicity of the structures involved in the attentional processes. Attention is involved, in fact, in several fundamental functions: Consciousness, perception, motor action, memory and so on. For several decades, the hypothesis that attention is highly variable (for extension and clarity) in terms of consciousness has been quite influential, which would range within itself in relation to its changes of state: From sleep to wakefulness, from drowsiness to twilight state of consciousness, from confusion to hyperlucidity, from dreamlike to oneiric states. More recently, other fields of considerable theoretical importance have linked attention to emotion, to affectivity or primary autonomous psychic energy or to social determinants. In this paper, we shall demonstrate how paying attention to something does not mean becoming aware of it. A series of experiments has shown that these are two distinct mental states. This decoupling could represent a useful mechanism for the ability to survive that has developed during the course of evolution. © Springer Nature Singapore Pte Ltd. 2020

    Orexin system: Network multi-tasking

    Orexin system regulates sleep/wake states and its deficiency result in narcolepsy thus indicating the crucial role of orexins in maintaining wakefulness. There are two types of orexin peptides: the orexin-A (OXA or hypocretin 1) and orexin-B (OXB or hypocretin 2). The Majority of the central nervous system orexin peptides are synthesized in neurons located in the lateral and back hypothalamus and send projections throughout the brain regions Orexin neurons are "multi-tasking" hence regulating also energy homeostasis, reward systems and feeding behaviour through connection with hypothalamic nuclei and through responsiveness to leptine and glucose. It has recently been found a connection with lymbic system suggesting a further possible role of orexins in regulating emotions. All the studies conducted confirm that orexin system regulates vigilance states, energy homeostasis, reward system, and emotions. These crucial role might be the target to develope treatments of narcolepsy, obesity, emotional stress, and drug addiction

    Mind, brain and altered states of consciousness

    The consciousness is the expression of an enormous and complex variety of neurobiological events, phenomenological and psychological that, from the early stages of development, prepare the emergence soil of the Self. It is a complex of tangible and intangible characters distinct from one another - neural infrastructure, awareness, temporality, qualitative subjectivity, intentionality - to such an extent as to seem welded faces of the same prism. Consciousness is not a simple function of the mind, but its organization. In this paper we intend to show how its order is not strictly hierarchical, but sustained by multiple horizontal levels, each of which in a structural and functional continuum with several emerging phenomena. The same distinction between quantitative aspects (surveillance) and qualitative (content of consciousness) of consciousness is founded on the premise that the supervision is regulated by widespread in projection systems of the brain stem, hypothalamus and thalamus; while the content of consciousness depends on the cortical activity, and particularly from the associative areas of the cortex connected between them. The so-called disturbances of consciousness (vegetative state, the minimally conscious state, a coma, the Locked in syndrome) suggests the existence of an alteration of a common underlying system. Although the current heterogeneity of the data makes it impossible to attribute with certainty whether positive or negative about the alleged absence of consciousness in the individual patient, the search is deriving significant benefits from the accumulation of neuroimaging evidence in paintings like coma, general anesthesia , sleep, epilepsy and somnambulism. In this sense, it seems increasingly urgent a deeper understanding of the neural correlates during sleep or general anesthesia, as well as the relationships between neural processes and altered states of consciousness generated by pharmacological manipulations
