  In this article, we explore the naming skills of a bilingual English- Norwegian speaker diagnosed with Primary Progressive Aphasia, in each of his languages across three different speech contexts: confrontation naming, semi-spontaneous narrative (picture description), and conversation, and at two points in time: 12 and 30 months post diagnosis, respectively. The results are discussed in light of two main theories of lexical retrieval in healthy, elderly speakers: the Transmission Deficit Hypothesis and the Inhibitory Deficit Theory. Our data show that, consistent with the participant’s premorbid use of and proficiency in the two languages, his performance in his L2 is lower than in his L1, but this difference diminishes as the disease progresses. This is the case across the three speech contexts; however, the difference is smaller in the narrative task, where his performance is very low in both languages already at the first measurement point. Despite his word finding problems, he is able to take active part in conversation, particularly in his L1 and more so at the first measurement point. In addition to the task effect, we find effects of word class, frequency, and cognateness on his naming skills. His performance seems to support the Transmission Deficit Hypothesis. By combining different tools and methods of analysis, we get a more comprehensive picture of the impact of the dementia on the speaker’s languages from an intra-individual as well as an inter-individual perspective, which may be useful in research as well as in clinical practice.

  This article investigates the cross-linguistic comparability of the newly developed lexical assessment tool Cross-linguistic Lexical Tasks (LITMUS-CLT). LITMUS-CLT is a part the Language Impairment Testing in Multilingual Settings (LITMUS) battery (Armon-Lotem, de Jong & Meir, 2015). Here we analyse results on receptive and expressive word knowledge tasks for nouns and verbs across 17 languages from eight different language families: Baltic (Lithuanian), Bantu (isiXhosa), Finnic (Finnish), Germanic (Afrikaans, British English, South African English, German, Luxembourgish, Norwegian, Swedish), Romance (Catalan, Italian), Semitic (Hebrew), Slavic (Polish, Serbian, Slovak) and Turkic (Turkish). The participants were 639 monolingual children aged 3;0 – 6;11 living in 15 different countries. Differences in vocabulary size were small between 16 of the languages; but isiXhosa-speaking children knew significantly fewer words than speakers of the other languages. There was a robust effect of word class: accuracy was higher for nouns than verbs. Furthermore, comprehension was more advanced than production. Results are discussed in the context of cross-linguistic comparisons of lexical development in monolingual and bilingual populations.

  This dissertation investigates how changes in language performance in Alzheimer's disease (AD) and primary progressive aphasia (PPA) can help shed light on theories of language processing, the mental lexicon, and how language impairments in dementia can help give a more comprehensive understanding of the complex difficulties associated with the different diseases. The dissertation is the first of its kind in Norway, focusing on language impairments in AD and PPA from a linguistic perspective. It contributes with new knowledge on deficits in lexical production and sentence comprehension in AD, PPA and healthy aging, shedding light on the structure of the mental lexicon in these populations. The results are in line with usage-based theories and interactive models of language processing, where the mental lexicon is seen as a structured network of smaller and larger units organized at different levels of abstractions, sensitive to effects of frequency, age of acquisition and cognate status. Furthermore, they support a notion that theories of language should consider the multilingual mental lexicon as default. The results also indicate that there may be two different variants of the logopenic subtype of PPA. The dissertation illustrates the advantage of using a range of different methods for assessing language to get a detailed picture of possible impairments. By means of eye-tracking, subtle differences in processing speed between healthy adults and persons with dementia could be detected that were not seen i a parallel offline task. A free word association task detected differences that were not captured with traditional naming tasks. Currently, language assessment plays a minor role in diagnosing dementia. However, this dissertation indicates that language data can add to diagnostic criteria for AD and PPA. While language difficulties in healthy aging can be seen as a continuum, the use of new methods and better assessment tools may contribute to both diagnosis and suggestions for possible treatment.

  The Language Assessment Remediation and Screening Profile (LARSP) is a language specific screening chart, developed to assess a child’s language skills and facilitate identification of specific language impairment (SLI) (Crystal, Fletcher and Garman, 1976). The chart can be used to assess child language development on word-, phrase- and clause level, across seven levels covering the age span from 0,9-6 years, and can be used both for clinical assessment and for cross-linguistic research. Originally developed from English, LARSP is now available in more than 20 languages, and soon also in Norwegian. In this talk we will outline how the Norwegian version of LARSP came to be, and look at similarities with and differences from other LARSP charts. For our adaptation, a preliminary profile chart was developed based on already existing data on Norwegian child language; from spontaneous speech (Simonsen, 1983; 1990; Anderssen 2006), experimental data (Ragnarsdottir et al 1999) and through the use of CDI (Simonsen, Kristoffersen et al., 2014, Kristoffersen & Simonsen, 2012). This chart was later validated by collecting data from 32 children (16 boys and 16 girls) between the ages 1;0 and 5;6 years. Each child was recorded at home with a parent present, twice in a six month period. 100 consecutive utterances from each recording were transcribed. These recordings were used to validate the preliminary chart and to investigate different micro-profiles of Norwegian child language acquisition (with focus on relative clauses and the use of root infinitives).
