- Memory conjunction errors, that is, when a combination of two previously presented stimuli is erroneously recognized as previously having been seen, were investigated in a face recognition task with drawings and photographs in 23 individuals with learning disability, and 18 chronologically age-matched controls without learning disability. Compared to the controls, individuals with learning disability committed significantly more conjunction errors, feature errors (one old and one new component), but had lower correct recognition, when the results were adjusted for different guessing levels. A dual-processing approach gained more support than a binding approach. However, neither of the approaches could explain all of the results. The results of the learning disability group were only partly related to non-verbal intelligence.

Speech-reading : Cognitive predictors and displayed emotion
- 1999
-
Ingår i: Scandinavian Audiology. - : Informa UK Limited. - 0105-0397. ; 28:4, s. 211-217

Tidskriftsartikel (refereegranskat)abstract
- The present study had three aims: to examine the effects of displayed emotion and message length on speech-reading performance, and how measures of working memory (cf. Baddeley 1986) and verbal information processing speed relate to speech-reading performance. Words and sentences with either positive or negative meaning were used in a word decoding and a sentence-based speech-reading test. A total of 48 normal-hearing subjects participated. The results revealed general effects of displayed emotion, message meaning and message length and no effect of displayed emotion vs message length. Furthermore, working memory but not verbal information processing speed nor accuracy predicted speech-reading performance. The results were discussed with respect to a model of face-processing (Bruce & Young 1986) and with respect to clinical implications.

Phonological representation and speech understanding with cochlear implants in deafened adults
- 1998

Ingår i: Scandinavian Journal of Psychology. - : Wiley. - 0036-5564 .- 1467-9450. ; 39:3, s. 175-179

Tidskriftsartikel (refereegranskat)abstract
- In the present study cognitive performance in 15 deafened adult cochlear implant candidates was examined and related to level of speech understanding after 12 months of experience with the implant. The implant group performed on par with normal hearing controls in all cognitive tasks used in the study with one exception: Performance was significantly lower in cognitive tasks where use of a phonological representation of sound is a key task-demand. Observations of the implanted individuals' level of speech understanding indicate that only those individuals who, pre-operatively, were in possession of phonological representations comparable to that of normal hearing could follow and understand a speaker that was out of sight. The results are discussed with respect to (a) deterioration in the phonological representation of sounds as a function of absence of external auditory stimulation, and (b) the role of cognitive factors in predicting success in speech understanding with the implant.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Sjukdomstillstånd och skador i organ och vävnader orsakar diverse funktionella avvikelser, som i sin tur ger upphov till symptom, som personen ifråga kan iaktta och lida av. Dessa orsakar funktionsnedsättningar, som påverkar individens möjligheter att fungera och klara sig i sin dagliga miljö hemma, i olika arbetssituationer och i olika sociala sammanhang.

Cognitive deafness : The deterioration of phonological representations in adults with an acquired severe hearing loss and its implications for speech understanding
- 2001
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the present thesis was to examine possible cognitive consequences of acquired hearing loss and the possible impact of these cognitive consequences on the ability to process spoken language presented through visual speechreading or through a cochlear implant.The main findings of the present thesis can be summarised in the following conclusions: (a) The phonological processing capabilities of individuals who have acquired a severe hearing loss or deafness deteriorate progressively as a function of number of years with a complete or partial auditory deprivation. (b) The observed phonological deterioration is restricted to certain aspects of the phonological system. Specifically, the phonological representations of words in the mental lexicon are of less good quality, whereas the phonological system in verbal working memory is preserved. (c) The deterioration of the phonological representations has a negative effect on the individual's ability to process speech, either presented visually (i.e., speechreading) or through a cochlear implant, as it may impair word recognition processes which involve activation of and discrimination between the phonological representations in the lexicon. (d) Thus, the present research describes an acquired cognitive disability not previously documented in the literature, and contributes to the context of other populations with phonological disabilities by showing that a complete or partial deprivation of auditory speech stimulation in adulthood can give rise to a phonological disability. (e) From a clinical point of view, the results from the present thesis suggest that early cochlear implantation after the onset of an acquired severe hearing loss is an important objective in order to reach a high level of speech understanding with the implant.

Phonological Deterioration in Adults with an Acquired Severe Hearing Impairment
- 1998
-
Ingår i: Scandinavian Audiology. - 0107-8593. ; 27:49, s. 93-100
-
Tidskriftsartikel (refereegranskat)abstract
- The study examined the phonological processing skills in a group of adults who have acquired a severe hearing loss in adult life. These severely hearing-impaired individuals performed at a significantly lower level on the rhyme judgement tasks and the letter span task, but on a par with the control group on other cognitive tests. A correlation analysis showed that duration of hearing loss is negatively related to performance on the rhyme judgement tasks and letter span task. The results indicate that the phonological processing skills in individuals who have acquired a severe hearing loss in adult life deteriorates. The results are discussed with respect to theoretical and clinical implications.
