O objetivo geral da presente tese foi investigar possíveis efeitos da atenção dividida da memória implícita perceptual não-verbal e verbal, e conceitual na fase de recuperação. Foram realizados dois estudos teóricos e um empírico. O primeiro estudo teórico teve o objetivo de revisar sistematicamente pesquisas que avaliaram o papel da atenção em testes de memória implícita (priming de repetição) com o paradigma da atenção dividida, na fase de codificação ou de recuperação. Foram selecionados 31 artigos empíricos com base em critérios pré-estabelecidos. Concluiu-se que os primings, perceptual e conceitual, são afetados pela atenção dividida na codificação quando a tarefa secundária demanda mais atenção, isto é, quando exige resposta frequente e é apresentada sincrônica ao estímulo alvo de memória. Poucos estudos foram realizados na fase de recuperação e indicaram imunidade desses primings à atenção dividida. O segundo estudo buscou apresentar e discutir aspectos metodológicos relevantes à elaboração de experimentos usando priming de repetição, com ênfase na seleção de materiais (software, listas de estímulos normatizados para o Brasil e relevância de fatores psicolinguísticos) e manipulação de variáveis (calibração pré-experimental, instruções e tempo de exposição dos estímulos, por exemplo). Recomendações para pesquisas futuras foram apresentadas. O artigo empírico foi o terceiro estudo e incluiu três experimentos. Os experimentos exploraram o papel da atenção na memória implícita perceptual não verbal e expandiram os resultados com testes perceptual e conceitual verbal, avaliando os efeitos da atenção dividida em novas condições experimentais. O experimento 1 utilizou o teste implícito de completar fragmentos de figuras com uma tarefa secundária de julgamento de tons; o experimento 2 utilizou completar radical de palavra e o experimento 3, produção de exemplar da categoria, ambos com uma tarefa secundária de julgamento de sequências de consoantes. Os resultados evidenciaram que a memória implícita foi afetada pela atenção dividida nos testes de completar fragmentos de figura e produção de exemplar da categoria, enquanto completar radical de palavra foi imune aos efeitos da divisão da atenção. Coletivamente, os resultados indicaram que, sob algumas circunstâncias, memória implícita perceptual exige recursos atencionais na recuperação. Recursos atencionais são exigidos pela memória implícita conceitual, tal como hipotetizado na literatura. / The general aim of this thesis was to investigate the role of attention in nonverbal perceptual implicit memory and expand knowledge on perceptual implicit memory and verbal conceptual. Two theoretical studies and one empirical were performed. The first theoretical study systematized research that evaluated the role of attention in implicit memory tests (repetition priming) with the paradigm of divided attention in encoding or retrieval phase. A total of 31 empirical articles based on pre-established criteria. The conclusion was that the primings, perceptual and conceptual, are affected by divided attention in encoding when the secondary task demands more attention, that is, when requires frequent response and it is presented synchronously to the memory target stimulus. Few studies was conducted in the retrieval phase and indicated that the primings are immune to divided attention. The second theoretical study aimed to present and discuss methodological aspects relevant to the elaboration of experiments using repetition priming, with emphasis on the selection of materials (software, standardized stimuli lists for Brazil and relevance of psycholinguistic factors) and variable manipulation (pre-calibration experimental, instructions and exposure time of the stimuli, for example). Recommendations for future research are presented. The empirical paper was the third study and included three experiments. The experiments explored the role of attention in nonverbal perceptual implicit memory and expanded the results with perceptual tests and verbal conceptual, evaluating the effects of divided attention on new experimental conditions. Experiment 1 used the implicit picture fragment completion test with a secondary task of judgment tones; Experiment 2 used word stem completion and the experiment 3, exemplary production category, both with a secondary task of judgment consonant sequences. The results showed that implicit memory was affected by divided attention in picture fragment completion and category exemplar production, while word stem completion was immune to the effects of divided attention. Collectively, the results indicated that, under some circumstances, perceptual implicit memory requires attentional resources in recovery. Attentional resources are required by the conceptual implicit memory, as hypothesized in the literature.

Durante o turno de trabalho em atividades repetitivas, foram avaliados 8 homens com idade entre 20 e 40 anos, com cronotipo moderadamente matutino, e dominância manual e visual direita. Os sujeitos foram submetidos a testes de alocação da atenção visual 6 vezes ao dia, em 9 dias. Os testes consistiam em manter o olhar fixo no centro da tela do computador, e responder o mais rapidamente possível a todos os estímulos que aparecerem. No experimento 1 (atenção explícita) devia-se prestar particular atenção à área de 4ox4o centrada no ponto de fixação, no experimento 2 (atenção dividida) devia-se prestar atenção simultaneamente a duas regiões de 4ox4o centradas lateralmente, a 10 o do centro. Os voluntários executaram a primeira tarefa sem problemas durante todo o turno de trabalho, com TRs médios mais rápidos no início da manhã (7h40min), e no início da tarde (14h20min). Quanto aos testes de atenção dividida, houve uma aparente oscilação no desempenho médio dos sujeitos a cada uma hora e vinte, com TRs mais rápidos nos mesmos horários (7:40 e 14:20). / During their worshift with repetitive activity, we evaluated 8 male subjects between 20 and 40 years old, right eye and hand dominance, and with moderate morningness chronotype. The subjects were submitted to tests of allocation of visual attention on 9 days. Tests consisted of fixing the point center of a computer screen and pressing a key as quickly as possible to any stimulus that they appeared anywhere on the screen. In experiment 1 attentioni should be focussed in a 4ox4o central area, whereas in experiment 2, attention should be divided simultaneously sideways, in two such 4ox4o areas, indicated by two lateral squares frames. Subjects easily focused attention in the center (experiment 1) throughout their workshift, whit quicker average of reaction times (RTs) at the beginning of the morning (7h40min), and at the beginning in the afternoon (14h20min). There was, on the other hand, an apparent oscillation in their ability to divide attentio with period of approximately 80 min. Again, mean RTs were faster at 7:40 and again at 14:20.

Syftet med följande arbete är att undersöka hur elever i årskurs 9 ser på sam- och särundervisning i ämnet idrott och hälsa med fokus på genus. Undersökningen har genomförts i form av en kvantitativ enkätundersökning (N=80). Denna undersökning visar att elever i årskurs 9 har olika tankar om hur de skall bli indelade i ämnet idrott och hälsa där en andel av eleverna anser att de skall delas in i samundervisning vid vissa moment medan andra elever anser att de skall delas in i särundervisning i vissa moment. Eleverna anser att de skall delas in i sam- eller särundervisning i olika områden i ämnet idrott och hälsa. Vissa elever anser att de skall ha samundervisning i området friluftsliv och en stor del av eleverna vill bli indelade i särundervisning när de skall ha simning i ämnet idrott och hälsa. Ett annat resultat som kom fram i undersökningen var att större delen av eleverna anser att de inte skall delas in i ämnet idrott och hälsa utefter kompetens medan en mindre del av eleverna anser att de skall delas in efter kompetens. I fortsatt forskning föreslås att man skulle kunna intervjua elever för att få djupare kunskap om varför de till exempel anser att de skall ha särundervisning i ämnet idrott och hälsa medan andra anser att de skall ha samundervisning. / This work is about how pupils in grade 9 look at cooperative education and divided education with focus on gender in the subject of physical education in school where a quantitative survey (N=80) was conducted. The purpose of the study was to investigate how pupils in grade 9 are looking at interpersonal education in the subject physical education with a gender perspective. The study is conducted in the form of quantitative survey. This study shows that pupils in grade 9 have different thoughts of how they should be divided in the physical education, where a proportion of the students in the study think that it should be a divided education at some points while other students consider that it should be cooperative education in some events. Some of the pupils in grade 9 consider that they should have cooperative education in outdoor education, while the results show that a large proportion of the students want to be divided when swimming is on the schedule. Another aspect that emerged from the survey was that most of the students consider that they should not be divided in terms of competence, while a minority of the students want to be divided according to competence. I am suggest that further research could interview students to get deeper answers to why they, for an example, will have cooperative education in physical education while other will have divided education. By conducting an interview , the investigator receives more specific answers than was done in this survey.

Název disertační práce v anglickém jazyce, abstrakt v anglickém jazyce a tři klíčová slova v anglickém jazyce Title: Legal aspects of state property management Abstract: When acting in the field of private law, State has the quality of a legal entity. However, State is a legal entity of its own kind. It has an immanent double nature and consequently it doesn't cease to stand on the border of private and public law. The principle of legality doesn't apply to State as a private law actor, which means that it can do even what is not explicitly permitted by the law. On the other hand, State cannot fully exploit autonomy of its will because its legal actions are rigorously predestined by the rules setting clear limits to it. Those limits in form of restrictive dispositions are addressed directly to organizational units of the state and state organizations and their purpose is to ensure efficient and economical management of state property as it is in the public interest. This dissertation aims to analyse the individual elements of property relations of the State. The most important subject in those relations is State itself. Nevertheless State cannot be regarded as one compact and confluent unity. On the contrary, its internal structure is crucial. The effects of internal structure of the State on the property...

This thesis will focus on split ticket voting. Split ticket voting refers to an aspect of voting behavior where the individual will cast votes for different political parties for different offices. Through the development of countless theories and utilizing data, political scientists have managed to shed some light as to why an individual may engage in split-ticket voting. However, many of these studies have been too narrow in their focus, for instance, relying on a specific election without taking into account some major variables that provide the foundation for voting behavior. The purpose of this study is to provide scholars with an idea of what characteristics exist most commonly among split-ticket voters compared with straight-ticket voters. What variables work together to cause an individual to engage in split ticket voting? Specifically, this thesis will examine the contribution of variables in explaining ticket splitting. Despite studies of the causes of split-ticket voting, the field is still unclear as to what causes an individual to engage in split-ticket voting. What individual variables cause an individual to engage in ticket splitting?

The concept of attention is complex and multifaceted and can be approached from many perspectives. One such perspective is of attention as a limited pool of resources. Kahneman’s (1973) model of limited capacity provides a basis for understanding constraints on attention, including the costs of divided attention. In the same vein as Kahneman’s model, the Framework for Understanding Effortful Listening (FUEL; Pichora-Fuller et al., 2016) applies the concept of limited attentional capacity to the demands of listening in a variety of contexts. The current work examines novel combinations of the methods commonly used in the field of Cognitive Hearing Science to address questions about the nature of attention allocation when listening in noise and under the constraints of divided attention. I first combined listening in noise with a secondary continuous working memory task and measured pupillary response as an index of cognitive work and listening effort. Here, I found that listening task demands affect performance on the working memory task. The shared demands of listening and working memory were not, however, evident in the pupil dilation patterns. As a result, I followed these findings by employing a different divided attention method. With the use of a temporally discrete secondary task that either closely overlapped with the listening task or did not closely overlap, I found the same carryover effects of listening demands on secondary task. Most importantly, I found that these demands interacted and were clearly present in the pupil dilation patterns, demonstrating the importance of the timing of the task demands. Together, the studies in this thesis provide evidence that these two secondary tasks access the same attentional resources as those accessed in the primary listening task and that this overlapping demand for resources can be seen in the pupillary response. / Thesis / Doctor of Philosophy (PhD) / Listening to speech in a noisy environment is a cognitively difficult and effortful task. Attending to more than one task at a time is similarly demanding and effortful. These two kinds of tasks are assumed to use the same limited pool of cognitive resources that we have available to us. This thesis combines listening in noise with divided attention tasks to demonstrate this overlap in demands for cognitive resources using novel combinations of these kinds of tasks. Additionally, this thesis uses the pupillary response—a well-studied index of cognitive effort—to further examine the nature of these overlapping task demands. These studies found that the demands of these tasks do, in fact, overlap, and contribute evidence to the current literature supporting the underlying assumption that these two tasks, and the pupillary response as a measure of effort, are accessing the same pool of limited resources.

<p>The psychological refractory period (PRP) paradigm has been used extensively to investigate the cognitive processing stages involved in dual-task performance. Interpretations of PRP data have often attributed the difficulty in simultaneously performing two cognitive tasks to a strict serial processing bottleneck in the response selection stage. However, a number of studies have also demonstrated backward response compatibility effects (BCEs) on Task 1 reaction time in dual-task performance, which suggest that response information for Task 2 may be activated in parallel with Task 1 response selection. The goal of this thesis was to examine the nature of the Task 2 processing that operates in parallel with Task 1 response selection in a PRP task, and to consider the implications of this parallel processing for models of dual-task performance. The results of the empirical studies presented here provide converging evidence that the BCE represents automatically activated response information for Task 2 acting on Task 1 response selection. This Task 2 response information can also contribute to Task 2 performance. Models of dual-task performance must account for both the parallel activation of response information and the serial selection of a response for each task.</p> / Doctor of Philosophy (PhD)

Listening ability is affected by external factors such as background noise and internal factors such as attention-allocation. I varied listening conditions and cognitive load and evaluated auditory word recognition and ratings of listening effort. Additionally, I investigated how individual differences in working memory capacity affected word recognition, recall, listening effort, and how working memory capacity interacted with other factors. Rönnberg et al.’s (2013) Ease of Language Understanding (ELU) model states that individual differences in working memory capacity will lead to differences in language comprehension in challenging listening conditions, where those with higher working memory capacity will be better at speech recognition. Using a dual-task experiment, participants heard and repeated words presented in three listening conditions: masked with pink noise, masked with babble, and processed through a hearing loss simulator. To manipulate cognitive load, participants completed the speech recognition task in both single- and dual-task paradigms. In the dual-task paradigm, participants continuously tracked a pseudo-randomly moving target on a screen for half the experiment. Participants reported perceived listening effort for each combination of listening condition and tracking condition. Additionally, memory for correctly heard words was tested with a recognition memory test. Word recognition performance and listening effort rating data agreed with my hypotheses that difficult listening conditions would produce poorer word recognition performance and increased listening effort. Interesting effects of cognitive load are discussed. The relation between working memory capacity and performance on various measures is also discussed in the context of the ELU model and theories of working memory capacity. Internal and external factors clearly interact to affect listening, and this interaction varies across individuals. / Thesis / Master of Science (MSc) / The ability to hear is affected by many factors, including attention and memory. The goal of this research is to investigate the cognitive factors (attention and memory) that affect hearing and how these effects differ on an individual level. My findings contribute to a better understanding of how background noise and mental demand affect hearing ability and listening effort, as well as how individual differences in cognitive ability further influence these factors. Results suggest that background noise and increased mental demand will decrease listening ability and increase listening effort. These changes in listening differ according to individual cognitive ability.

Dual task studies have found that Task 2 response information is activated during Task 1 response selection, and can have a priming effect on Task 1. This is called the backward compatibility effect (BCE). Giammarco et al. (2016) found that single-task practice of Task 2 in the context of a random, filler task (Practice-T2 condition) extinguished BCE development in a subsequent dual-task. On the other hand, practicing Task 2 in the context of Task 1 (Practice-Both condition) promoted BCE development in subsequent dual-tasks. Experiment 1a sought to replicate this context-specific disruption of BCE development by presenting participants with a single-task practice phase where they practiced Task 2 along with a filler task, and then observed BCE development in a subsequent dual-task phase. Experiment 1b addressed a counterbalancing issue in Experiment 1a. Experiment 2 was an exact replication of the Practice-T2 condition used in Giammarco et al. (2016). Overall, we conceptually replicated the context-specific disruption of BCE in Experiment 2, but not in Experiments 1a and 1b. Further study is warranted to determine the effect of specific response features on the learning context of Task 2. / Thesis / Master of Science (MSc) / Backward compatibility effects (BCEs) have been consistently observed in dual task paradigms. BCEs occur when Task 1 and Task 2 response information are congruent: participants respond faster to Task 1 when the two tasks require congruent responses than when they require incongruent ones. This suggests that there is some parallel processing of Task 2 while performing Task 1. The purpose of this study was to explore the episodic account of BCE development. Since episodic memories are context-specific, BCEs should also be context-specific, according to the episodic account. By manipulating the context of Task 2 learning, we tested whether this affected subsequent BCE development. Our findings suggest that context-specific disruption of BCE development is possible, but depends on other factors as well.
