Working in noisy environments can be detrimental to cognitive performance. In order to perform well people have to find a way to attenuate distraction. This thesis aimed to study the balance between distractibility and task demands in the context of office-related tasks as a means by which to better understand how people in the work environment are influenced by environmental noise. In Report 1, 2 and 3 higher focal-task difficulty was achieved by manipulating the readability of the text that participants were asked to read (i.e. either displaying the text in hard-to-read font or by masking it with static visual noise). The results of Report 1 and Report 2 showed that background speech impaired performance on proofreading and memory for written stories respectively compared to silence, but only when the focaltask difficulty was low, not when it was high. In Report 3 it was shown that background speech, road traffic noise, and aircraft noise impaired performance on text memory compared to silence, but again, only when focal-task difficulty was low. In Report 4 it was tested whether higher cognitive load on the focal task would reduce peripheral processing of a to-be-ignored background story. The results of Report 4 showed that participants in the low-load condition recalled more of the information conveyed in the to-be-ignored background story compared to participants in the high-load condition. It was also investigated whether individual differences in working memory capacity (WMC) would influence participants’ memory for written stories (Report 2) and incidental memory of the to-background story (Report 4) differently depending on task demand. The results showed that individuals scoring high on the WMC-test were less distracted by background speech in the easy-to-read font condition (Report 2), and recalled less of the information in the to-be-ignored background story in the low-cognitive load condition (Report 4) compared to individuals that scored lower on the WMC-test. These relationships were not found in the hard-to-read font condition in Report 2, or in the high-cognitive load condition in Report 4. Taken together, these results indicate that higher focal-task difficulty can shield against the detrimental effect environmental noise on performance on office-related tasks. Moreover, it shows that higher focal-task difficulty can help individuals with low-WMC to reach a level of performance that is similar to that of high-capacity individuals. / Människor som arbetar inom den byggda miljön (t.ex. kontor eller skolor) är ofta exponerade för olika typer av miljöljud (t.ex. bakgrundsprat, vägtrafiks- eller flygplansbuller) som kan ha en negativ inverkan på deras förmåga att prestera på kognitiva uppgifter (t.ex. läs- eller skrivuppgifter). För att kunna prestera behöver de som arbetar inom den byggda miljön hitta ett sätt att minska hur distraherade de blir av bakgrundsbuller när de arbetar med kontorsrelaterade uppgifter (t.ex. korrekturläsning eller minne för text). Syftet med denna avhandling var att studera balansen mellan distraktion och koncentrationskrav på arbetsuppgiften som ett sätt att undersöka vilken inverkan bakgrundsbuller i arbetsmiljön har på människors förmåga att prestera på kontorsrelaterade uppgifter. I Rapport 1, 2 och 3 manipulerades koncentrationskravet på arbetsuppgiften genom att göra texten mer svårläslig (d.v.s. antingen använda ett mer svårläsligt teckensnitt eller genom att maskera texten med ett visuellt brus). Resultaten på Rapport 1 och 2 visade att bakgrundsprat försämrade prestationen på ett korrekturläsningstest och ett textminnestest jämfört med en tyst betingelse, men bara när texten var lättläslig och inte när den var svårläslig. Rapport 3 visade att bakgrundsprat, vägtrafikbuller och flygplansbuller försämrade prestationen på ett textminnestest jämfört med tystnad, men återigen, bara när texten var lättläslig och inte när den var svårläslig. I Rapport 4 undersöktes om ökad kognitiv belastning på en arbetsuppgift skulle minska hur mycket information av ett bakgrundsprat (d.v.s. en berättelse om en fiktiv kultur) som deltagarna kunde återge trots att de blivit instruerade att ignorera det som sades i bakgrunden. Resultatet visade att deltagarna i betingelsen med låg kognitiv belastning kom ihåg mer av informationen från bakgrundsberättelsen jämfört med deltagarna med hög kognitiv belastning. Denna avhandling undersökte också sambandet mellan individuella skillnader i arbetsminneskapacitet och storleken på hur distraherad individen var av bakgrundsprat (Rapport 2), samt sambandet mellan arbetsminneskapacitet och hur mycket individen mindes av det bakgrundsprat de blivit instruerade att ignorera (Rapport 4), och om dessa samband influerades olika beroende på koncentrationskravet på arbetsuppgiften. Resultatet i Rapport 2 visade att individer med hög arbetsminneskapacitet blev mindre distraherade av bakgrundspratet jämfört med individer med låg arbetsminneskapacitet på prosaminnestestet, men bara när texten var lättläslig, inte när den var svårläslig. Rapport 4 visade att i betingelsen med låg kognitiv belastning kom de med hög arbetsminneskapacitet ihåg mindre av bakgrundsberättelsen jämfört med individerna med låg arbetsminneskapacitet, men när den kognitiva belastningen var hög var det ingen skillnad i hur mycket deltagarna kom ihåg av bakgrundsberättelsen mellan individer med hög och låg arbetsminneskapacitet. Sammanfattningsvis visar resultaten att ökat koncentrationskrav på en arbetsuppgift, genom att öka svårighetsgraden (t.ex. genom att använda ett mer svårläsligt teckensnitt), kan skydda mot den negativa inverkan som bakgrundsbuller har på arbetsuppgifter som liknar de människor arbetar med på kontor. Vidare visade resultaten att ökade koncentrationskrav på arbetsuppgiften kan hjälpa individer med låg arbetsminneskapacitet att prestera i paritet med individer med hög arbetsminneskapacitet när arbetsuppgiften utförs i bakgrundsprat.

This study aims to find out the relationship between Working Memory Capacity and Verbal and Mathematical Achievement. The participants were 60 students at Hacettepe University School of Foreign Languages Department of Basic English. For measuring working memory capacity, one simple (Digit Span Task) and one complex (Reading Span Task) were used. Verbal achievement of the participants was measured both in their native language (Turkish) and their foreign language (English). For measuring their native language achievement, the participants&rsquo / Turkish scores in Y&uuml / ksek&ouml / gretime Ge&ccedil / is Sinavi 2010 (Transition to Higher Education Examination) / and for measuring their foreign language achievement, the participants&rsquo / scores in Hacettepe University School of Foreign Languages Department of Basic English Elementary Groups Achievement Exams I and II were used. For measuring their mathematical achievement, the participants&rsquo / Mathematic scores in Y&uuml / ksek&ouml / gretime Ge&ccedil / is Sinavi 2010 (Transition to Higher Education Examination) were used. The data was analyzed using a statistical package program (SPSS Version 18.0). The data analysis results revealed that there is a relationship between working memory capacity and verbal and mathematical achievements of the participants. It was tentatively concluded that, as the working memory capacity of the participants increase, so might their achievement in verbal and mathematical subjects. This result was discussed in terms of its implications, which may be that, if working memory capacity could be improved / the cognitive processes which the working memory is responsible for might also improve.

Maintaining health and quality of life into old age is a critical issue facing society today. Language, and in particular language comprehension, is vulnerable to the processes of ageing (Au, Albert, & Obler, 1989; Kynette & Kemper, 1986; Nicholas, Obler, Albert, & Goodglass, 1985; Shewan & Henderson, 1988). An improved understanding of language processing and ageing will assist in distinguishing language difficulties in normal ageing from those in pathological ageing and aphasia (Maxim & Bryan, 1994) and, potentially, optimises communication throughout life. The current thesis focuses on a specific component of language comprehension - anaphora resolution . Anaphora resolution occurs frequently in everyday discourse and has been reported to decline with ageing (Cohen, 1979; Light & Capps, 1986; Ulatowska, Hayashi, Cannito, & Fleming, 1986). This thesis explored anaphora resolution relative to two key variables: ageing and working memory. Ageing was chosen as a variable as anaphora resolution has been shown to be affected by age (Cohen, 1979; Light & Capps, 1986; Ulatowska et al., 1986). Working memory was chosen as working memory is thought to underlie key aspects of discourse comprehension such as building a mental structure of discourse and updating the information (Brébion, 2003; Hasher & Zacks, 1988; Radvansky, Copeland, & Hippel, 2010; Radvansky, Lynchard, & von Hippel, 2009). Anaphora resolution was investigated using two key paradigms. The first focussed on anaphora resolution in a reading comprehension task. Performance was assessed using accuracy of response. The second employed Gernsbacher's (1989) probe-response paradigm. The probe- response paradigm allowed examination of specific working memory processes underlying discourse comprehension, namely; a) storing and maintaining information in working memory (i.e., laying the foundation of the discourse structure); and b) updating information stored in working memory through suppressing the irrelevant discourse information. Storage and maintenance of the information was assessed by examining whether participants utilised “advantage of first mention” (Gernsbacher, 1990). Suppression was evaluated by investigating whether the accessibility of nonreferent names decreased in participants' working memory after they read anaphoric pronouns in sentences. This approach aimed to answer the following questions: 1) Do age and working memory capacity affect anaphora resolution in a comprehension task?; 2) Do age and working memory affect advantage of first mention in a probe recognition task?; and 3) Does age affect suppression of irrelevant information in an anaphora resolution task? In Chapter 3, Gernsbacher's (1989) original study was replicated. In Chapter 4 the same questions were examined, with the addition of a higher working memory load. For both studies, 30 younger and 30 older participants completed two comprehension experiments followed by an assessment of working memory capacity (reading span task). The comprehension experiments each contained a reading comprehension task and a probe recognition task. The reading comprehension task introduced two discourse characters (either a male or female name), one of which was referred to later in the text, using an anaphoric pronoun. Comprehension questions always asked about the referents of the anaphoric pronouns. Participants' accuracy in answering each comprehension question was indicative of their ability to resolve anaphora. Response times in the recognition task provided measures of the accessibility of: a) first and second mentioned names, and b) referent and nonreferent names. Chapters 3 and 4 found that, regardless of the tasks' working memory storage demands, older adults were less accurate than younger adults in the comprehension of anaphoric pronouns. Comprehension accuracy was related to working memory capacity, such that individuals with higher working memory capacity exhibited higher accuracy of response in the comprehension task. In addition, working memory capacity affected the accessibility of first and second mentioned names in the discourse suggesting that working memory capacity might influence the process of laying the foundation for the mental representation of comprehension. An ageing effect was observed on the suppression process during anaphora resolution under high working memory load only. When working memory load was low, neither younger nor older participants suppressed the accessibility of the nonreferents by the time they finished reading the sentences. This suggested that anaphora resolution might be postponed in less demanding tasks. However, under higher working memory load, younger adults, but not older adults, suppressed the accessibility of the nonreferents by the time they finished reading the sentence. It was therefore suggested that age-related changes in anaphora resolution abilities might be mediated by a decline in inhibitory functions that are responsible for suppressing the already-activated information that are no longer relevant to the task goals. The final study of the thesis (Chapter 5) aimed to determine why younger adults delayed the process of anaphora resolution in Experiment 1 (See Chapter 3), but completed the process by the time they finished reading the sentences in Experiment 2 (See Chapter 4). Specific questions addressed were: 1) Was comprehension accuracy affected by working memory storage load and the syntactic structure of the sentences?; 2) Do younger adults suppress the accessibility of the nonreferents by the time they reach the end of the sentence, in simpler sentences with increased storage load and late disambiguation?; and, 3) Do younger adults suppress the accessibility of nonreferents by the time they reach the end of the sentence, in more syntactically complex sentences with low storage load and prior disambiguation?. Forty younger participants completed four separate comprehension experimental tasks followed by a reading span test. A similar experimental approach was employed to that described in Chapters 3 and 4; however working memory storage load, syntactic complexity, and time-course for providing contextual information were manipulated. Results of Chapter 5 found that participants' accuracy declined in more syntactically complex sentences. A decline in accuracy appeared indicative of the tasks' higher processing demands and demonstrated that prior disambiguation was not facilitating the resolution of anaphora. Results from the recognition task showed that in sentences of increased syntactic complexity, participants suppressed the accessibility of nonreferents by the time they finished reading the sentence. It was suggested that higher processing demands of syntactically complex sentences, rather than a facilitating effect of earlier disambiguation in these sentences, contributed to the earlier suppression of nonreferents. In summary, this thesis demonstrated that older adults were less accurate than younger adults in comprehending anaphoric pronouns. Moreover, working memory capacity positively influenced comprehension accuracy and affected the advantage of first mention of discourse entities. It was suggested that individual differences in working memory capacity might affect the ability to lay foundations for discourse comprehension. Furthermore, older adults showed no suppression of nonreferents during processing of anaphora, regardless of working memory storage load. It appears possible that older adults' difficulty in anaphora resolution might be due to an inability to suppress irrelevant discourse information. Findings from the present study suggest that ageing may negatively affect the comprehension of linguistic structures for which more than one meaning could be inferred. While further exploration of this finding is required, it is possible that communication strategies could be devised to minimise the use of structures with more than one meaning - with the aim of improving and maintaining communication in older adults. Ultimately, determining the underlying causes of language impairments in both healthy ageing and neurological disease will help to improve speech-language therapy methods for these populations.

Les différences interindividuelles en mémoire de travail (MDT) ont un lien stable et largement documenté avec la performance dans les tâches de cognition de haut niveau. Dans la mesure où l'utilisation de stratégies efficaces joue un rôle aussi bien dans les tâches de MDT que de cognition de haut niveau, on peut faire l'hypothèse que les stratégies médiatisent le lien entre ces deux construits. De fait, certaines données suggèrent que le comportement stratégique au sein de tâches de cognition de haut niveau pourrait être en lien avec la capacité de MDT. L'objectif de ce travail de thèse était d'évaluer ce lien de façon plus poussée. Cette approche nous a conduit à deux résultats particulièrement significatifs. Le premier concerne le développement et la formalisation du paradigme de Hard Fall Effect (HFE), défini comme étant la chute de performance plus importante en situation de double tâche pour les participants avec une forte capacité de MDT. L'hypothèse sous-jacente à cet effet est que ces participants utilisent des stratégies afin d'améliorer leurs performances en situation de simple tâche, et que la situation de double tâche perturbe l'utilisation de ces stratégies. Au cours de ce travail, le HFE a notamment été mis en évidence dans une tâche de mémoire visuospatiale, et a pu être attribué à l'utilisation de stratégies d'encodage plus efficaces par les participants avec une forte capacité de MDT au sein de tâches de mémoire complexes. Notre second résultat significatif correspond au test direct de l'hypothèse de médiation du lien entre MDT et cognition de haut niveau par l'utilisation de stratégies efficaces en cognition de haut niveau. Nous avons montré que lorsqu'on contrôle la variance associée à l'utilisation de stratégies efficaces dans la tâche des Matrices Avancées de Raven, la relation entre capacité de MDT et intelligence fluide diminue. Dans l'ensemble, ces deux résultats permettent de renforcer l'idée selon laquelle le comportement stratégique impliqué dans les tâches de cognition de haut niveau intervient dans la relation entre MDT et cognition de haut niveau. / The relationship between individual differences in working memory capacity (WMC) and high-level cognition has been extensively documented. Since efficient strategy use plays an important role in the performance of both working memory and high-level cognitive tasks, it could be the case that strategies mediate the WM-high-level cognition relationship. Importantly, it has been observed that the use of efficient strategies in high-level cognitive tasks is related to individual differences in WMC. The goal of this research work was to investigate this association between WMC and the use of efficient strategies in more detail. Firstly, we formalized a paradigm termed the Hard Fall Effect (HFE), defined as a larger decrease of performance in dual task conditions for high WMC individuals. The underlying interpretation of this effect is that these individuals use efficient strategies under simple task conditions to improve their performance, and these strategies are disrupted by dual tasking. The present work evidenced the HFE in a visuospatial memory task, and attributed the effect to the higher tendency of high WMC individuals to use efficient encoding strategies in complex memory tasks. Secondly, we provided evidence that efficient strategy use in high-level cognitive tasks partly mediates the WMC-high-level cognition relationship. More precisely, when statistically controlling the use of efficient strategies in Raven's Advanced Progressive Matrices, the WMC-fluid intelligence relationship was significantly reduced. Overall, these two results provide evidence that the use of efficient strategies in high-level cognitive tasks is involved in the WMC-high-level cognition relationship.

Most of these studies involve oral languages, but there is still a lack of research on the relationship between CMT and sign language performance. In addition, it is necessary to verify the functionality of the multicomponent MT model (BADDELEY, 2000) for sign language (CORINA; KNAPP, 2006; EMMOREY, et al., 2008), observing the role of each subsystem Phonological buffer, episodic buffer and visuospatial sketch). In view of this, the following research question arises: How could be a Work Memory test that adequately measures the storage and processing capacity of information in Libras (Brazilian Sign Language)? The present work aims to elaborate and evaluate a test in Libras, denominated of Libras span that aims to retain signals in order of appearance and at the same time to say if these signals involve or not during their realization. This test was applied to a group of users of Libras (deaf and hearing) and correlated with numerical-based MT tests, known as digit span whose task is to remember numbers in ascending order and operation span whose task is to solve calculations and remember the last digits of each operation. The purpose of this correlation was to evaluate the reliability and validity of the test with signals. Results showed that the Libras span task can become a good tool for assessing working memory capacity in Libras / O construto cognitivo de memória de trabalho (doravante MT) tem se mostrado de extrema relevância no desenvolvimento e uso linguístico, havendo evidências de associação entre maior capacidade de memória de trabalho (doravante CMT) e melhor desempenho na L2 (ORTIZPREUSS; SANZ, 2016). A maioria desses estudos envolvem línguas orais, mas ainda há carência de pesquisas sobre a relação entre CMT e o desempenho em língua de sinais. Além disso, é preciso verificar a funcionalidade da arquitetura do modelo de multicomponente MT (BADDELEY, 2000) para a língua de sinais (CORINA; KNAPP, 2006; EMMOREY, et. al., 2008), observando o papel de cada subsistema (alça fonológica, buffer episódico e esboço visuoespacial). Em vista disso, surge a seguinte questão de pesquisa: Como poderia ser um teste de Memória de Trabalho que meça adequadamente a capacidade de armazenamento e processamento de informações em Libras? O presente trabalho tem como objetivo elaborar um teste em Libras, denominado de Libras span, cuja tarefa é memorizar sinais em ordem de aparecimento e, ao mesmo tempo, dizer se esses sinais envolvem ou não contato durante sua realização. Este teste foi aplicado a um grupo de usuários de Libras (surdos e ouvintes) e correlacionado com testes de MT de base numérica, conhecidos como digit span, cuja tarefa requer lembrar números em ordem crescente e operation span, cuja tarefa requer resolver cálculos e lembrar os últimos algarismos de cada operação. O propósito dessa correlação foi avaliar a confiabilidade e a validade do teste com sinais. Os resultados mostraram que, embora sejam necessários mais alguns ajustes, a tarefa Libras span pode tornar-se um bom instrumento de avaliação da capacidade de memória de trabalho em Libras.

Age can affect memory performance. This statement is so often heard that it has become almost a truism. When research surrounding memory inhibition – the ability to ignore irrelevant material to aid in the retrieval of a target memory – is examined specifically, a more mixed picture of findings emerges. Whilst some previous work has found evidence of an age-related deficit, other research has rather found intact memory inhibition in older adults. Less often discussed, too, are the effects of individual differences on memory inhibition in addition to age, including differences in metacognitive strategy, working memory capacity, stress and mood. The present thesis set out primarily to investigate the effects of age on memory inhibition chiefly using cognitive experimental paradigms, and also to investigate potential individual differences in this ability which exist across the lifespan. The findings of the present thesis showed that age alone was not related to a deficit in memory inhibition, - young and older adults rather showed equivalent levels of inhibitory forgetting on two different paradigms, when methodological measures were put in place to control for alternative, interference-based explanations (Study 1). These findings also could not be explained by differences in metacognitive, covert-cuing strategies (Study 2). Instead, age-related inhibitory deficits were qualified by differences in working memory capacity (Study 3a & b). In combination, older age and low working memory capacity were related to impaired memory inhibition, whereas young age or high working memory capacity were not. Finally, natural variations in stress and mood over time were found to be related to significant differences in working memory capacity, but not memory inhibition (Study 4). This suggests that these important cognitive abilities may be capable of changing even over relatively short time periods, and thus they may also potentially be improved, - a proposal which is considered in the General Discussion.

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.

Under de senaste åren har intresset för test baserat lärande ökat och det förekommer evidensatt detta fenomen fungerar inom flera områden som bland annat test format, personligaegenskaper samt återkoppling från ett test. En aspekt som det däremot finns få studier av ärtestbaserat lärande i relation till individuella skillnader i kognition. Den föreliggande studienfokuserar därför på individuella skillnader avseende arbetsminneskapacitet och episodisktminne och dess effekter på ihågkomst av svenska-swahili-ordpar. I studien ingick 163gymnasieelever, varav 82 var flickor och 81 var pojkar med en medelålder om 17.10 år.Multipla regressionsanalyser undersökte deltagarnas förmåga att minnas 60 svenska-swahiliordparfyra veckor efter inlärningsperioden. Analysen visade att både arbetsminneskapacitetoch episodiskt minne predicerar långtidsretention för studerade ordpar. För testbaserat lärandevar det endast det episodiska minnet som signifikant predicerade retentionen. Studien indikeraratt det episodiska minnet, är centralt både för att studera ordpar och att lära in ordpar genomtestbaserat lärande. Däremot är det enbart arbetsminnet som har betydelse för att lära sig ordparvia att studera ordparen. / During the last years, the interest for test-enhanced learning have increased and robust evidenceconcerning test format, personal characteristics and feedback have been obtained. However,few studies have examined test-enhanced learning in relation to cognition. The present studytherefore focused on examine the individual differences in working memory capacity and theepisodic memory and the effects of those on recall of Swedish- Swahili word pairs. The studyincluded 163 students whereof 82 girls were and 81 were boys, with a mean age of 17.10 years.Multiple regressions investigated whether the participated could correctly recall 60 Swedish-Swahili word pairs four weeks after the learning session. The analysis showed that both theepisodic memory and working memory capacity predicted long-term retention for studied wordpairs. For test based learning only the episodic memory had a significant prediction for longterm retention. The study indicate that the episodic memory is central both for learning throughstudy and learning through test-enhanced learning. While working memory was important onlylearning through study.
