The relationship between inferential processing and text processing: a developmental study
The research reported here was designed to investigate the critical role played by certain factors implicated in the mental representation of text, and to establish whether their role varies significantly as a function of developmental age. Specifically, it was decided to analyse, in a sample of 180 subjects was selected from three different age groups (7, 10 and 18 years of age respectively), the role of such factors in mediating and influencing the generation of the inferences needed to understand a piece of text characterised by a sequence of information which flows in a logical order, but leads to a conclusion which is contrary to the expectations evoked by the text. In line with this objective, it was decided to take into account factors related to encoding (added information about the key object â a title), those involved in recall (inferential tests regarding the object and action of change), as well as purely metacognitive factors, such as evaluation of oneâs own comprehension and awareness of textual incongruence, whose presence, according to our assumptions, should facilitate the formulation of inferential hypotheses. It would thus seem that inferential processing is powerfully influenced both by cognitive and structural factors, factors which can play a role during both encoding and recall. The results reported here tend to confirm the hypothesis that there is indeed a significant developmental trend in the role played by those factors involved in the coherent representation of text and in the formulation of inferences. The data suggest that children in the youngest age group obtain the greatest advantage from clues in reaching a more correct representation of the text concerned. It is concluded that inferential processes do not serve only to make connections between propositions, but to construct a coherent mental representation of text (Kintsh, 1994; Zwaan, 1994, 1996)
Down Syndrome and Referential Communication: Understanding and Production
This study aimed to evaluate the ability of referential communication in subjects with Down Syndrome (DS). We evaluated the possibility that the referential communication is the result of a set of cognitive factors, verbal and nonverbal through the evaluation of relationship between cognitive abilities in individuals with DS and typically developing. In particular, we have identified some critical dimensions of communicative function, such as the referential communication, which means the subject's ability to produce o the listener or messages "referentially oriented", ie messages that are characterized by "clarity or ambiguity referential ". The referential communication skills, intended both as production (speaker condition) and as understanding (listener condition). Furthermore, has been decided to deepen their understanding through a test that assesses understanding of the text. This choice stems from the need to investigate whether the understanding of a text for individuals with DS could be easier than the understanding of individual messages. It is assumed in fact, that understanding of a text works as a facilitator in coherent mental representation of the text, compared to a single message
Linguistic prosody and comprehension of idioms and proverbs in subjects of school age
A crucial component of language is represented by the prosodic system because it provides essential elements to speaker about how a sentence should be interpreted or intended (Fodor, 2002). Increasing interest from researchers also relates to the understanding of figurative language (Levorato, & Cacciari, 2002). In the figures of speech that the speaker wants the listener intends something more or different than what is explicitly stated (Glucksberg, 2001)..
In particular, prosodic intonation is crucial in the resolution of syntactic ambiguity and structural features that constitute the complex messages, such as idioms and proverbs.
A crucial component of language, therefore, is represented by the prosodic system because it provides essential elements to talking about how a sentence should be interpreted or understood . The ability to relate to metalinguistic understanding the cognitive processes that allow you to reflect on language and manipulate its characteristics. These capabilities are essential to recognize and resolve the ambiguities of a complex message, you can control and plan the way we produce and understand language (Levorato, 2007).
The study demonstrates that an understanding prosodic correlates with the understanding of idioms and proverbs, which are crucial for the achievement of metalinguistic awareness, are influenced by the level of schooling and socio-cultural
The impact of soil erosion on soil fertility and vine vigor. A multidisciplinary approach based on field, laboratory and remote sensing approaches
Soil erosion processes in vineyards, beyond surface runoff and sediment transport, have a strong effect on soil organic carbon (SOC) loss and redistribution along the slope. Variation in SOC across the landscape can determine differences in soil fertility and vine vigor. The goal of this research was to analyze the interactions among vines vigor, sediment delivery and SOC in a sloping vineyard located in Sicily. Six pedons were studied along the slope by digging 6 pits up to 60 cmdepth. Soilwas sampled every 10 cm and SOC, water extractable organic carbon (WEOC) and specific ultraviolet absorbance (SUVA) were analyzed. Erosion rates, detachment and deposition areas were measured by the pole height method which allowed mapping of the soil redistribution. The vigor of vegetation, expressed as Normalized Difference Vegetation Index (NDVI), derived from highresolution satellite multispectral data, was compared with measured pruning weight. Results confirmed that soil erosion, sediment redistribution and SOC across the slope was strongly affected by topographic features, slope and curvature. The erosion ratewas 16Mg haâ1 yâ1 since the timeof planting (6 years). SOC redistribution was strongly correlated with the detachment or deposition areas as highlighted by pole height measurements. The off-farm SOC loss over six years amounted to 1.2 Mg C haâ1. SUVA254 values, which indicate hydrophobic material rich in aromatic constituents of WEOC, decreased significantly along the slope, demonstrating that WEOC in the detachment site ismore stable in comparison to deposition sites. The plant vigor was strongly correlated with WEOC constituents. Results demonstrated that high resolution passive remote sensing data combined with soil and plant analyses can survey areas with contrasting SOC, soil fertility, soil erosion and plant vigor. Thiswill allowmonitoring of soil erosion and degradation risk areas and support decision-makers in developing measures for friendly environmental management
Modelling soil carbon fate under erosion process in vineyard
Soil erosion processes in vineyards beyond water runoff and sediment transport have a strong effect on soil organic carbon loss (SOC) and redistribution along the slope. The variation of SOC across the landscape determines a difference in soil fertility and vine productivity. The aim of this research was to study erosion of a Mediterranean vineyard, develop an approach to estimate the SOC loss, correlate the vines vigor with sediment and carbon erosion. The study was carried out in a Sicilian (Italy) vineyard, planted in 2011. Along the slope, six pedons were studied by digging 6 pits up to 60cm depth. Soil was sampled in each pedon every 10cm and SOC was analyzed. Soil erosion, detachment and deposition areas were measured by pole height method. The vigor of vegetation was expressed in term of NDVI (Normalized difference Vegetation Index) derived from a satellite image (RapidEye) acquired at berry pre-veraison stage (July) and characterized by 5 spectral bands in the shortwave region, including a band in the red wavelength (R, 630-685 nm) and in the near infrared (NIR, 760-850 nm) . Results showed that soil erosion, sediments redistribution and SOC across the hill was strongly affected by topographic features, slope and curvature. The erosion rate was 46Mg ha-1 y-1 during the first 6 years since planting. The SOC redistribution was strongly correlated with the detachment or deposition area as highlighted by pole height measurements. The approach developed to estimate the SOC loss showed that during the whole study period the off-farm SOC amounts to 1.6Mg C ha-1. As highlighted by NDVI results, the plant vigor is strong correlated with SOC content and therefore, developing an accurate NDVI approach could be useful to detect the vineyard areas characterized by low fertility due to erosion process
THE QUALITY OF LIFE IN CHILDREN WITH CEREBRAL PALSY
Background: Cerebral palsy (CP) is the most common pediatric disability causing long-term functional limitations. CP
remarkably influences the life of those affected and their families. For this reason it is important and necessary to direct attention not
only type of the CP, but also the impact the disorder has on the child, parents, siblings and the entire family as a whole. The aim of
this study was to assess the impact of CP on the childâs quality of life, considering parentsâ perceptions about their child's illness, in
order to underline the impact the illness has not only on the child but also his/her family.
Methods: The study included both parents of the 36 subjects enrolled (19 males and 17 females), with established CP diagnosis.
The effect of CP on the families was assessed using the Impact of Childhood Illness Scale. This questionnaire assesses the quality
of life in children with epilepsy and other chronic pathologies and in their families. All questions refer to effect to the illness family.
The scale comprises 30 questions divided into four sections: impact of illness and its treatment ; impact on development and child s
adjustment; impact on parents and impact on the family. Descriptive analyses were used for data analysis and it is also calculated
the rank correlation coefficient Spearmanâs rho.
Results and conclusion: The mothersâ group presents little higher average scores than the group of fathers in two four subscales
or in the basement âImpact on the childâ and âFamily impact on the organizationâ. This could be due to the fact that mothers are
concerned most of the child's caregiver, living most of all the difficulties that entails; mothers show greater concerns than fathers. In
subscale âImpact on parentsâ the average score of the answers of the group of mothers coincide with that of the fathers; the experience
and the experience of his son's illness is analogous for both parents. No significant differences were found from the correlational
analysis between the individual items of the subscales and the different forms of CP. In families of children with CP, strategies for
optimizing caregiver physical and psychological health include supports for behavioral management and daily functional activities
as well as stress management and self-efficacy techniques
Internalizing symptoms in children affected by childhood absence epilepsy: A preliminary study
Introduction: Childhood absence epilepsy (CAE) is a common type of pediatric idiopathic generalized epilepsy, characterized by multiple seizures of typical absence, with typical EEG pattern consisting in bilateral synchronous and symmetrical discharges of generalized 3 Hz spike-wave (SWDs). Recently, some researchers have suggested that the underlying epileptogenic mechanism of absence seizures selectively involves the frontal cortical circuits, also supported by video-electroencephalography data(3). These data may be considered as a new window in CAE comprehension and management, particularly about symptoms different from seizure that children affected may present. In this light, aim of the present study is evaluating the presence of internalizing problems in prepubertal children affected by CAE. Material and methods: 18 patients (10 females, 8 males) ranging age from 8-11 years (mean age 9.36 ± 1.32) affected by typical CAE were recruited. Control group was composed by 43 subjects (32 females, 11 males) (mean age 8.54 ± 2.01). All subjects were screened for internalizing symptoms with SAFA-A scale and CDI test. Results: The two groups were comparable for age (p=0.117) and sex distribution (p=0.251). CAE children showed significantly higher score than controls for anxiety (p<0.001) and depressive symptoms screening tests (p<0.001) (Table 1). Conclusions: Results of present study suggest the importance of screening for anxiety and depressive signs in CAE children, in order to optimize their management beyond the exclusive idea to control and stop epileptic seizure only
Neuropsychological Alterations in Children Affected by Obstructive Sleep Apnea Syndrome
Sleep-related breathing disorders are a group of clinical conditions ranging from habitual snoring to obstructive sleep apnea syndrome (OSAS) during the lifespan. In children, other risk factors are represented by adenotonsillar hypertrophy, rhinitis, nasal structure alteration, cleft palate, velopharyngeal flap surgery, pharyngeal masses, craniofacial malformations, genetic syndrome (i.e. Down syndrome, Crouzon syndrome, and Apert syndrome), genetic hypoplasia mandibular (i.e. Pierre Robin syndrome, Treacher Collins syndrome, Shy-Drager syndrome, and Cornelia De Lange syndrome), craniofacial traumas, chronic or seasonal rhinitis, asthma, neuromuscular syndromes, brainstem pathologies (i.e. Arnold-Chiari malformation and Joubert syndrome), achondroplasia, and mucopolysaccharidosis. OSAS may affect the executive functioning such as motivational ability, planning, behavior modulation, ability to complete an action program, identification of functional strategies to achieve the goal, problem solving, flexibility, monitoring and self-assessment of behavior in relation to results, change of task, or behavior in the light of emerging information, which may be all impaired by nocturnal intermittent hypoxia also during the developmental age. The clinical presentation of OSAS can mimic other neurobehavioral symptoms, such as ADHD syndrome, learning problems, or can exacerbate the Fragile X syndrome, and generalized non-convulsive epilepsy symptoms
