Syftet med föreliggande studie var att ta fram ett svenskt material för att undersöka mottagligheten för semantiska illusioner vid bearbetning av auditivt språkligt meddelande hos vuxna individer utan kommunikationsstörning. Utöver detta syftade även studien till att undersöka om mottaglighet för den semantiska illusionseffekten är relaterad till lexikal åtkomst och arbetsminneskapacitet. I studiens initiala skede utformades det nya testmaterialet Auditivt test av mottaglighet för semantiska illusioner (ATSI). ATSI består av tre deltest, varje deltest innefattar 40 påståenden med en jämn fördelning av sanna påståenden, falska påståenden och illusoriska påståenden. Deltagarna i studien bestod av 30 vuxna individer utan kommunikationsstörning. Deltagarnas uppgift var att avgöra om påståendena i ATSI var sanna eller falska. Utöver ATSI utförde även deltagarna test gällande lexikal åtkomst och arbetsminneskapacitet. Effekten av semantiska illusioner analyserades genom t-test och visade att illusionseffekten var statistiskt signifikant. Resultaten från ATSI korrelerades med deltagarnas prestation gällande lexikal åtkomst och arbetsminneskapacitet. Hur lurade deltagarna blev av den semantiska illusionseffekten korrelerade med lexikal åtkomst. I föreliggande studie kunde inget samband observeras mellan hur lurade deltagarna blev och arbetsminneskapacitet. I diskussionen förs i föreliggande studie resonemang kring varierande metodologiska aspekter likväl som resultatens implikationer för den språkliga bearbetningsprocessen. Slutsatsen i föreliggande studie är att den semantiska illusionen är ett stabilt fenomen som har effekt vid bearbetning av språkligt meddelande auditivt. / The aim of this study was to construct a Swedish test material in order to examine the susceptibility for semantic illusions in adults without any communication disorders when processing verbal input of language. Furthermore the study aimed to investigate if the susceptibility for semantic illusions relates to the individual’s lexical access speed and working memory capacity. In order to accomplish the aim of the study, a new auditory test material called Auditivt Test av mottaglighet för Semantiska Illusioner (ATSI) was created. ATSI consists of three separate test sections, each containing 40 statements with an even distribution of true statements, false statements and statements containing the semantic illusion. The participants had to decide whether each statement was true or false. The participants in this study consisted of 30 adult individuals without communication disorders. Furthermore the participants performed test regarding lexical access speed and working memory capacity. The effects of semantic illusions were analyzed trough t-tests and found to be statistically significant. Correlation analysis were made between result from ATSI and lexical access speed as well as between results from ATSI and working memory capacity. How tricked the participants were by the semantic illusions was related to lexical access, but not working memory capacity. Methodological aspects are discussed in this study as well as the result’s implication for language processing. The conclusion is that semantic illusions is a stabile phenomenon, and it occurs when processing spoken sentences.

Children with Reading and Writing Difficulties and Their Language and Cognitive Abilities A Comparison with Children with a Cochlear Implant Abstract The aim of this study was to examine the cognitive abilities that are important for reading in children with reading disabilities, children with a cochlear implantation and typically developed children. 64 children aged 10-12 years participated in the study. To answer the question at issue we used the following tests: Block Design from WISC III, PPVT III, TOWRE, SL 40 and a few chosen tests out of the SIPS battery. On tests of the lexical access children with reading disabilities performed at the same level as hearing children, while the children with a cochlear implant performed significantly lower. Test of the phonological and complex working memory showed that children with reading disabilities performed significantly higher than children with a cochlear implant, but at the same time lower than typically developed children on the test of phonological working memory. Tests of reading ability showed that children with a cochlear implant performed at the same level as typically developed children, while children with reading disabilities showed lower results. The results indicate that the children with a cochlear implant can develop an adequate reading ability in spite of their phonological difficulties. Phonological skills do not seem to be the only factor influencing reading ability of the examined groups.

Recent empirical studies about the neurological executive nature of reading in bilinguals differ in their evaluations of the degree of selective manifestation in lexical access as implicated by data from early and late reading measures in the eye-tracking paradigm. Currently two scenarios are plausible: (1) Lexical access in reading is fundamentally language non-selective and top-down effects from semantic context can influence the degree of selectivity in lexical access; (2) Cross-lingual lexical activation is actuated via bottom-up processes without being affected by top-down effects from sentence context. In an attempt to test these hypotheses empirically, this study analyzed reader-text events arising when cognate facilitation and semantic constraint interact in a 22 factorially designed experiment tracking the eye movements of 26 Swedish-English bilinguals reading in their L2. Stimulus conditions consisted of high- and low-constraint sentences embedded with either a cognate or a non-cognate control word. The results showed clear signs of cognate facilitation in both early and late reading measures and in either sentence conditions. This evidence in favour of the non-selective hypothesis indicates that the manifestation of non-selective lexical access in reading is not constrained by top-down effects from semantic context. / Dagens eye-trackingstudier över de neurologiska processer som styr läsning i tvåspråkiga är oeniga om graden av icke-selektiv aktivation som infinner sig inuti den tvåspråkiges mentala lexikon enligt kvantitativa data på tidiga och sena åtkomstsstadier. Två olika förhållningssätt till frågan finns: (1) Lexikal åtkomst är fundamentalt sett icke-selektiv, men top-down effekter från semantisk kontext kan influera den grad av selektiv åtkomst som påträffas i mentala lexikon; eller (2) Parallell aktivation av olika språkplan sker via bottom-up processer utan någon inverkan ifrån top-down effekter ifrån meningskontext. För att testa dessa hypoteser undersöktes läsprover framtagna genom att kontrollera kognatförenklingseffekten och kontextskapad ordförutsägbarhet i en 22 faktorial stimulusdesign. 26 tvåspråkiga (svenska L1, engelska L2) läste meningsstimuli på engelska. Stimulus bestod av meningar med hög eller låg grad av semantisk och lexikal priming som innehöll antingen ett kognat- eller ett ickekognatkontrollord. Resultaten visade klara tecken på kognatförenkling i tidiga såsom sena åtkomstsstadier för båda typers meningsstimuli. Dessa resultat förespråkar att icke-selektiv åtkomst  i läsning inte påverkas av top-down effekter ifrån meningskontext. / <p>Författaren heter numer Mattias Bystedt.</p>
