From Controlled to Automatic Processes and Back Again: The Role of Contextual Features

In cognitive psychology, classical approaches categorize automatic and controlled processes from a dichotomous point of view. Automatic processes are believed to be rigid, whereas controlled processes are thought to be flexible. New theories have softened this dichotomous view. The aim of the present study is to examine the possibility of implementing flexibility in automatic processing through reliance on contextual features. One hundred and twenty subjects (mean age 22.4, SD = 4.2), 60 male and 60 female, participated in this study. An automatic sequence task (with and without contextual features) was used to test flexibility in automatic processing. Results showed that the use of contextual cues can increase flexibility in automatic processes. The results are discussed in light of new theories on softened automaticity

The executive functions in a sample of Italian adults with ADHD: attention, response inhibition and planning/organization

Adults with attention-deficit/hyperactivity disorder (ADHD) show an impaired functioning in multiple cognitive domains: executive functioning (EF), attention, response inhibition, planning and organization, reward and timing. However, the neuropsychological profile of these patients is unclear. Investigations of neuropsychological functioning in a sample of Italian adults with ADHD are currently lacking. The present study aimed at examining neuropsychological performance on tasks measuring executive functioning, attention response inhibition, planning and organization, comparing adults with ADHD (N= 23, mean age 19,7; SD= 3,27) and healthy adults (N= 23, mean age 19,7; SD= 3,27) matched for age and gender. Results showed that adults with ADHD present impaired EF, response inhibition and disorganization/planning. By contrast, they didn’t exhibit attention deficits. This study supports the persistence of cognitive impairments in subjects with ADHD also in adulthood

Adult listening behaviour, music preferences and emotions in the mobile context. Does mobile context affect elicited emotions?

After the introduction of mobile computing devices, the way people listen to music has changed considerably. Although there is a broad scientific consensus on the fact that people show music preferences and make music choices based on their feelings and emotions, the sources of such preferences and choices are still debated. The main aim of this study is to understand whether listening in ecological (mobile) contexts differs from listening in non-mobile contexts in terms of the elicited emotive response. A total of 328 participants listen to 100 classical music tracks, available through an ad-hoc mobile application for mobile devices. The participants were asked to report their self-evaluation of each of the tracks, according to the Pleasure-Arousal-Dominance model and filled out a questionnaire about their listening behaviour. Our findings show that the same factors that affect music listening in non-mobile contexts also affect it in a mobile context

The influence of cognitive factors on pathological gambling

The purpose of this study wasto examine the role of cognitive factors, such as superstition, locus of control, decision-making and unrealistic optimism,on gambling.Eighty-six subjects participated in this study. They were divided into four groups: non-players, social players, problem gamblers, and pathological gamblers. Groups were formed on the basis of South Oaks Gambling Screen  Scale. Results showed that pathological gamblers group obtained a high superstition index. With reference to unrealistic optimism, gambler groupbelieved that they had a better chance of success compared to non-gamblers. They also showed a higher impulsivity index in decision making than non-gamblers. This study supports the idea that cognitive factors such as superstition, unrealistic optimism, impulsivity and external locus of control are involved in gambling

Morphological and Structural Evaluation of Hydration/Dehydration Stages of MgSO4 Filled Composite Silicone Foam for Thermal Energy Storage Applications

Salt hydrates, such as MgSO4·7H2O, are considered attractive materials for thermal energy storage, thanks to their high theoretical storage density. However, pure salt hydrates present some challenges in real application due to agglomeration, corrosion and swelling problems during hydration/dehydration cycles. In order to overcome these limitations, a composite material based on silicone vapor-permeable foam filled with the salt hydrate is here presented. For its characterization, a real-time in situ environmental scanning electron microscopy (ESEM) investigation was carried out in controlled temperature and humidity conditions. The specific set-up was proposed as an innovative method in order to evaluate the morphological evolution of the composite material during the hydrating and dehydrating stages of the salt. The results evidenced an effective micro-thermal stability of the material. Furthermore, dehydration thermogravimetric/differential scanning calorimetric (TG/DSC) analysis confirmed the improved reactivity of the realized composite foam compared to pure MgSO4·7H2O.This work was partially funded by the Ministerio de Ciencia, Innovación y Universidades de España (RTI2018-093849-B-C31). This work was partially supported by ICREA under the ICREA Academia program

Attention, problem solving and decision making in adult subjects with ADHD

Although attention-deficit/hyperactivity disorder (ADHD) is clearly associated with executive dysfunctions, the neuropsychological profile of adults with ADHD is unclear. The present study aimed at examining neuropsychological performance on tasks measuring attention, problem solving and decision making, comparing adults with ADHD (N= 12, mean age 18.33; SD= 11.48) and healthy adults (N= 12, mean age 18.41; SD= 18.70) matched for age and gender. Results showed that adults with ADHD exhibit deficits in attention, problem solving and decision making. These findings warrant further examination of neuropsychological profile in adults with ADHD to improve the understanding of underlying neurocognitive mechanisms

The importance of gravity vector on adult mammalian organisms: Effects of hypergravity on mouse testis

In the age of space exploration, the effect of hypergravity on human physiology is a relatively neglected topic. However, astronauts have several experiences of hypergravity during their missions. The main disturbance of altered gravity can be imputed to cell cytoskeleton alteration and physiologic homeostasis of the body. Testis has proved to be a particularly sensible organ, subject to environmental alteration and physiological disturbance. This makes testis an organ eligible for investigating the alteration following exposure to altered gravity. In our study, mice were exposed to hypergravity (3g for 14 days) in the Large Diameter Centrifuge machine (ESA, Netherland). We have observed a morphological alteration of the regular architecture of the seminiferous tubules of testis as well as an altered expression of factors involved in the junctional complexes of Sertoli cells, responsible for ensuring the morpho-functional integrity of the organ. The expression of key receptors in physiological performance, such as Androgen Receptors and Interstitial Cells Stimulating Hormone receptors, was found lower expressed. All these findings indicate the occurrence of altered physiological organ performance such as the reduction of the spermatozoa number and altered endocrine parameters following hypergravity exposure

Use of a low-tech tool in the improvement of social interaction of patients with Rett Syndrome: an observational study

IntroductionThe main aim of the present study was to examine whether the use of a low-tech tool, called click4all, inserted into cognitive and motor training can increase social interaction of patients with Rett Syndrome (RTT) with classmates in a school setting.MethodsTwenty-seven participants with RTT were randomly assigned to two groups: the experimental group received treatment with click4all, and the control group received traditional treatment without click4all. Parameters were measured before treatment (T1), 6 months after treatment (T2), 6 months after the second treatment phase (T3) and at the end of the third treatment phase (T4).ResultsThe results demonstrated an increase in levels of social interaction among classmates and patients with RTT in the experimental group, over time, compared to the control group, 95% CI [5.20–15.30]. Classmates also showed a higher level of knowledge related to participants of the experimental group, and this increased over time, 95% CI [24.98–63.52]. The level of knowledge related to the control group was stable over time and lower than the experimental group.DiscussionThis study demonstrated that the use of a low-tech tool can increase social interactions of patients with RTT in a school setting. This is important, as patients with RTT are often restricted in an isolation condition

The TCTRS Project: A Holistic Approach for Telerehabilitation in Rett Syndrome

Telerehabilitation (TR) has been proven to be an effective tool in improving the adaptive skills of children and young adults with Multiple Disabilities (MDs). The application of a comprehensive set of new technologies reveals new opportunities for both physical and cognitive telerehabilitation, but there is no holistic approach in the case of genetic syndromes. In this paper we present reflections and early results of the TCTRS project that aims at implementing a telerehabilitation system capable of offering complete coverage of rehabilitation needs for people with Rett Syndrome, from both the physical and cognitive points of view. Moreover, the data acquired through the system can also represent a basis for machine learning applications to remotely support therapists and physicians. Our first tests on the system application show the great potential of our approach, in terms of feasibility and applicability, for both rehabilitation centers and families
