  1. 1. Blindness and Second Language Acquisition : Studies of Cognitive Advantages in Blind L1 and L2 speakers

    Författare :Helena Smeds; Niclas Abrahamsson; Lars-Göran Nilsson; Loraine Obler; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Early blindness; late blindness; L1 speakers; L2 speakers; cognitive advantages; second language acquisition; phonological short-term memory; recognition memory; episodic memory; speech perception in noise; accentedness in L2 speech; Bilingualism; tvåspråkighet;

    Sammanfattning : The aim of this study is to investigate whether blind individuals display cognitive advantages over sighted individuals with regard to second language acquisition. Previous studies from neuropsychology have indicated that this is the case. LÄS MER

  3. 2. Auditory and Olfactory Abilities in Blind and Sighted Individuals : More Similarities than Differences

    Författare :Stina Cornell Kärnekull; Maria Larsson; Mats E Nilsson; Johan Willander; Fredrik U Jönsson; Johannes Frasnelli; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; absolute threshold; audition; autobiographical memory; blindness; discrimination; episodic recognition; identification; imagery; judgments of learning; memory; metacognition; olfaction; onset age of blindness; reminiscence bump; sensory compensation; Psychology; psykologi;

    Sammanfattning : Blind individuals face various challenges in everyday life because of the lack of visual input. However, since they need to rely on the non-visual senses for everyday tasks, for instance, when navigating the environment, the question has been raised as to whether perceptual and cognitive abilities in these senses may be enhanced.

  4. 3. On the necessity of screening and national registration of congenital cataracts

    Författare :Gunilla Magnusson; Göteborgs universitet; []
    Nyckelord :congenital cataract; glaucoma; intraocular surgery; posterior capsular opacification PCO ; prevalence; visual acuity VA ; visual impairment; screening; newborn examination; blindness prevention; cost-utility analysis; quality- adjusted life year QALY ;

    Sammanfattning : Objectives: The overall aim of this thesis was to contribute to improvements in the management of congenital cataract by defining the most efficient screening procedure, examining the magnitude of the morbidity rate, optimizing the timing of surgery by relating surgical outcome to age at intervention and severity of visual deprivation and furthermore by evaluating costs versus consequences of introducing the most efficient screening procedure found, on a national basis.Methods: Paper I: 72 children born between 1992 and 1998 in the Stockholm County Council region, Västra Götaland and Halland county, Linköping-Motala, Malmö, and Lund, who had surgery for congenital cataract before the age of one year were included in a retrospective study.

    Sammanfattning : The general objective of this thesis was to describe a system for fundus photography for early diagnosis of diabetic retinopathy, performed by mobile teams visiting primary health care centres in Stockholm County. Large-scale implementation showed this method to be feasible, acceptable, and popular. LÄS MER
