Visual Working Memory in Deaf Children with Diverse Communication Modes: Improvement by Differential Outcomes
Peer reviewed Peer reviewed
Direct linkDirect link
Lopez-Crespo, Ginesa; Daza, Maria Teresa; Mendez-Lopez, Magdalena – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
Although visual functions have been proposed to be enhanced in deaf individuals, empirical studies have not yet established clear evidence on this issue. The present study aimed to determine whether deaf children with diverse communication modes had superior visual memory and whether their performance was improved by the use of differential…

Galli, Manuela; Cimolin, Veronica; Vismara, Luca; Grugni, Graziano; Camerota, Filippo; Celletti, Claudia; Albertini, Giorgio; Rigoldi, Chiara; Capodaglio, Paolo – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Prader-Willi syndrome (PWS) and Ehlers-Danlos syndrome (EDS) are two different genetical disorders both characterized, among other features, by muscular hypotonia. Postural control seems to be impaired in both conditions. The aim of the present study was to quantitatively compare postural control in adult PWS and EDS using stabilometric platform…

Fabio, Rosa Angela; Giannatiempo, Samantha; Antonietti, Alessandro; Budden, Sarojini – Research in Developmental Disabilities: A Multidisciplinary Journal, 2009
Ten Rett syndrome (RS) girls and 10 control girls executed an attentional task in which a complex stimulus was shown followed by individual stimuli presented with distractors. Participants had to discriminate previously presented stimuli from distractors. RS girls carried out the task both in a condition with the containment of stereotypies and in…
