No full textIL FUOCO ATTENTIVO: ALCUNE QUESTIONI IRRISOLTE
No full textIn questo lavoro si indaga su alcune questioni ancora irrisolte sul fuoco attentivo:
i margini del fuoco sono definiti e differenziati dalle zone circostanti non interessate
dall’attenzione? Le differenze nella prestazione in un compito di detezione sono
spiegabili efficacemente con l’ipotesi del dimensionamento del fuoco attentivo in base
alle richieste del compito? Le differenze nella prestazione sono di natura attentiva e
non attribuibili a effetti retinici? I risultati depongono a favore di una risposta affermativa
per tutte le domande sopra esposte
Non-spatial attentional shifts between audition and vision
No full textThis study investigated nonspatial shifts of attention between visual and auditory modalities. The authors
provide evidence that the modality of a stimulus (S1) affected the processing of a subsequent stimulus
(S2) depending on whether they shared the same modality. For both vision and audition, the onset of S1
summoned attention exogenously to its modality, causing a delay in processing S2 in a different modality.
That undermines the notion that auditory stimuli have a stronger and more automatic alerting effect than
visual stimuli (M. I. Posner, M. J. Nissen, & R. M. Klein, 1976). The results are consistent with other
recent studies showing cross-modal attentional limitation. The authors suggest that such cross-modal
limitation can be produced by simply presenting S1 and S2 in different modalities and that central
processing mechanisms are also, at least partially, modality dependent

No full textOur study examined the complex relationships among reading performance (decoding, comprehension) and language, visuo-spatial, and attentional control abilities in 115 Italian-speaking children. Latent profile analysis was used to identify distinct clusters of participants showcasing quantitative differences in decoding skills, including word, pseudo-word, text reading speed and accuracy. Then, we used this classification to investigate group differences in a variety of linguistic, working memory, and visuo-spatial tasks, as well as in reading comprehension skills, by means of multivariate and univariate tests. Our results reveal significant links between reading proficiency and several key factors: language skills, visuo-spatial abilities, and attentional control. These findings illuminate the nuanced impact of domain-general processes that govern a series of linguistic and visuo-perceptive subcomponents during reading tasks. Additionally, using dominance analysis, predictors of written text comprehension were identified. Our findings suggest that effective reading comprehension relies on a synergistic interplay of adequate reading speed, attentional control, working memory, and verbal fluency, accounting for 23% of the explained variance. This study highlights the multifaceted nature of reading proficiency and suggests that a broader perspective is necessary to fully understand reading development and support its improvement
