Cognitive processes related to problematic pornography use (PPU): A systematic review of experimental studies
2021
Highlights • Some people experience symptoms derived from pornography viewing. • Cognitive processes may be related to the development of Problematic Pornography Use (PPU). • We performed a systematic review of 21 studies exploring cognitive processes related to PPU. • We identified 4 cognitive processes relevant for the development and maintenance of PPU.
Serum Response Factor-Mediated Gene Regulation in a Drosophila Visual Working Memory
2013
Summary Background Navigation through the environment requires a working memory for the chosen target and path integration facilitating an approach when the target becomes temporarily hidden. We have previously shown that this visual orientation memory resides in the ellipsoid body, which is part of the central complex in the Drosophila brain. Former analysis of foraging and ignorant mutants have revealed that a hierarchical PKG and RSKII kinase signaling cascade in a subset of the ellipsoid-body ring neurons is required for this type of working memory in flies. Results Here we show that mutants in the ellipsoid body open ( ebo ) gene, which encodes the actin-binding protein Exportin 6, e…
Percezione aptica e schema corporeo in soggetti con obesità grave
Apprendere una seconda lingua da analfabeti tra ricerca e didattica. Una esperienza con i minori stranieri non accompagnati a Palermo
This contribution presents data and experiences acquired within the frame of the “Inclusion Project Linguistic School of Italian Language for Foreigners” of the University of Palermo. The program, created five years ago, has designed and managed educational courses for adults and unaccompanied minors (msna) of low and very low schooling level, most of them between 16 and 18 years old, and developed a series of social initiatives related to the insertion of these minors in Sicilian Society. These youths are part of a large number of unaccompanied adolescents who, in recent years, have come ashore to the port of Palermo along with thousands of refugees and asylum seekers. A significant number…
Aging and prospective memory: the role of working memory and monitoring processes
2008
Background and aims: Remembering to execute an earlier planned action is essential in everyday life, and is a prerequisite for independent living in old age. The purpose of the present study was to determine the influence of age in performing a prospective memory (PM) task and to analyze the differential contribution of working memory and attentional monitoring demands. Methods: In Experiment 1, a group of young and two groups of old adults were assigned to one of two low-demanding conditions: a picture-naming task (only-Naming) and a picture-naming plus a PM task (Naming+PM). In Experiment 2, a group of young and two groups of old adults performed one of two high-demanding conditions, in w…
Robotic and virtual World Programming labs to Stimulate Reasoning and visual-spatial Abilities
2013
Abstract The individuals’ cognitive skills, academic performance and their relationship with programming of robots or virtual learning environment is a topic of particular interest in the area of human-robot interaction. This paper presents a pilot study performed on a group of 36 lower secondary school students involved in a 32-hours laboratory based on the combination of LEGO Mindstorm NXT and Microsoft Kodu Game Lab (KGL) and aimed at programming first a robot and further a more complete virtual world based on a narrative-designed scenario. The findings of the research will be discussed in the light of the effectiveness of using robotics and virtual world programming as a meaningful and …
The role of working memory on writing processes.
2021
Literature has extensively demonstrated the coordination role of working memory (WM) in complex tasks such as writing. However, previous studies mostly concentrated on the relation between passive WM (e.g., WM span) components and specific writing tasks (e.g., dictation). Here, we aimed to investigate the relationship between different writing skills and the performance on a WM updating task measuring the more active components of WM. From a pool of 160 Italian pupils (grades 3–5), we selected 46 children divided in two groups based on their WM updating performance. The first group consisted of 21 children with low WM updating performance (≤10th percentile), the second group consisted of 25…
Naming speed and Effortful and Automatic Inhibition in Children with Arithmetic Learning Disabilities
2009
Abstract We report a two-year longitudinal study aimed at investigating the rate of access to numerical and non-numerical information in long-term memory and the functioning of automatic and effortful cognitive inhibition processes in children with arithmetical learning disabilities (ALDs). Twelve children with ALDs, of age 9.3 years, and twelve gender–age-matched controls were involved in the study. Rate of access was measured through digit- and letter-naming tasks, automatic cognitive inhibition was measured using a negative priming paradigm, and effortful cognitive inhibition was measured rating intrusion errors in a working memory task. Children with ALDs suffered from a deficit in the …
Naming speed, automatic inhibition and effortful inhibition in a working memory task in children with arithmetic learning difficulties.
2008
We report a study aimed at investigating rate of access to numerical and non-numerical information in long-term memory and functioning of automatic and effortful cognitive inhibition processes in children with Arithmetical Learning Disabilities (ALD). A group of children with ALD, of age 10,3 years, and a group of gender-age-matched controls were involved in the study. Rate of access was measured through digit- and letter- naming tasks, automatic cognitive inhibition was measured using a negative priming paradigm, and effortful cognitive inhibition was measured rating intrusion errors in the well known Daneman and Carpenter’s (1980) working memory task. No evidence for dysfunction of the au…
PML Prove per la misurazione della memoria di lavoro. Vol. 2
2020
Il PML-2 è un innovativo ed efficace strumento per la misurazione della Memoria di Lavoro in età evolutiva (dai 6 ai 16 anni) che si contraddistingue, rispetto ad altri strumenti simili, per l'ampiezza delle variabili di memoria che riesce a misurare (verbale, visuo-spaziale, numerica, ecc.) e per la precisione con cui valuta anche i processi esecutivi e la velocità di elaborazione. La PML-2 è particolarmente utile per la valutazione della memoria di lavoro in soggetti con disturbi del neurosviluppo e in soggetti con disturbi specifici dell'apprendimento.
