Previous research has demonstrated a retrieval-induced forgetting effect for verbal material (Anderson & Spellman, 1995), colours and shapes (Ciranni & Shimamura,1999), eyewitness testimony (MacLeod, 2002), and images of novel actions (Koutstaal et al., 1999). However, little research has been conducted into retrieval-induced forgetting and self-performed actions. A recent study by Sharman (2011) demonstrated retrieval-induced forgetting for familiar and bizarre self-performed actions. The current thesis aims to examine retrieval-induced forgetting and actions including self-performed and observed actions, and combinations of self-performed and observed actions. The first experiment demonstrated retrieval-induced forgetting for novel motor sequences. In addition, retrieval-induced forgetting was also found for less novel actions (Experiments 3 and 4) for both typical and non-typical self-performed actions (Experiment 3) and memorable self-performed actions (Experiment 4). Experiment 2 demonstrated a retrieval-induced forgetting effect for objects associated with actions suggesting that retrieval-induced forgetting effects occur both for the action and the object. However the findings of experiment 5 suggest that retrieval-induced forgetting may not occur for goal-orientated actions. These experiments may suggest that retrieval-induced forgetting occurs for non goal-orientated actions, but may not occur for goal-orientated actions. These findings are discussed in terms of the inhibitory account.

<p>Fizička aktivnost u velikoj meri može pozitivno uticati na zdravstveni status i psihosocijalno stanje, pa je glavni cilj istraživanja bio usmeren na analizu fizičke aktivnosti pred&scaron;kolske dece. Teorijski deo rada obuhvata sve &scaron;to je bitno za razumevanje postavljene teme, dok je empirijski deo podeljen na četiri dela. U prvom delu su izloženi rezultati dobijeni anketom i dnevnikom aktivnosti koje su popunjavali roditelji, a analizirana je dečja aktivnost radnim danima i vikendom. Drugi deo se odnosi na obim kretne aktivnosti dece tokom boravka u vrtiću, gde je statističkom obradom podataka utvrđeno kakav je obim kretne aktivnosti dečaka i devojčica i od čega zavisi. U okviru plana i programa koji se sprovodi u pred&scaron;kolskoj ustanovi, predviđeno je da se upražnjavaju usmerene aktivnosti s motoričkim sadržajem, &scaron;to je analizirano u trećem i četvrtom delu (trajanje, struktura i sadržaj aktivnosti, kao i motorička&nbsp; angažovanost dece na aktivnostima).</p> / <p>Physical activity can have a positive impact on the health status and psychosocial condition; therefore the main aim of this research was focused on the analysis of physical activities of preschool children. The theoretical part of the study includes all important matters essential for understanding the subject, while the empirical part is divided into four sections. The first section presents the results obtained from a questionnaire and a diary of activities completed by parents, and it analyzes the children&#39;s activity on weekdays and weekends. The second section relates to the extent of motor activity of children during their stay in the kindergarten. The statistical analysis in this section shows the scope of motor activity of boys and girls and what it depends on. According to the plan implemented in preschool institution, it is expected to have directed activities with motor content. This part is analyzed in the third and fourth section (duration, structure and content of activities as well as motor<br />involvement of children in activities).</p>

Title: The evaluation of gross motor function and coordination in primary school children Defining the issue: The physical activity and sport are highly discussed topics in current time. The physical activity itself has a positive effect on our body in many ways, on the contrary the lack of it has a negative effect. In the younger school age there should be a diversity of physical activity and it should often vary. If, in this period of age, the physical activity would be in the form of specialized sport training with dominant asymetric load without any compensating activity, the effect of that training would be probably negative and even harming for the growing body of young children, who are not prepared for that type of burden. To ensure an adequate development of specific skills and gaits the appropriate level of gross motor function and coordination is required. The evaluation of such movement features after reaching bipedal locometion is mediocre at best and the current test batteries are limited in application. For these reasons the goal was to create new battery of tests and use it to evaluate the gross motor function and coordination in primary school children and assessment of the impact of gender and extracurricular activity on the results. The purpose of the study: The purpose of this...

Name of the thesis: Testing of motor performance of high school students in Kadaň and their relationship to physical activities Objectives of the thesis: The objective of the thesis is to analyze the level of basic motor performance of high school students in Kadaň and find out their relationship to physical activities Method: This thesis is processed in the form of empirical quantitative research. The research is realized in the type of environment where is possible to eliminate influences of external environment, that is in a gym. The research subject were students of two chosen high schools, both male and female. Of the total number of 232 students, 143 were female and 89 male aged 15-17. To find out the level of motor performance of the students the test battery UNIFITTEST (6-60) was used. To gather information about the relationship of students to physical activities and competitiveness, a short poll of eight items was made. These were focused on the gathering of basic anamnestic data like name and surname, date of birth, the name of the school they attend to and grade in physical education. Furthermore, it was important to find out if and how often the student takes part in physical activity in his or her free time. Specifically, these questions were divided into involvement of a student in a...

The puberty has not been a stage of life few studied, except for researches in human adolescents, that presents phase delay in sleep-wake cycle. However, few studies have focused on the basis of this circadian change due to methodological difficulties. Thus, an animal model to study the sleep-wake cycle at puberty is essential. In the common marmoset, a social primate, the circadian activity periodicity stabilizes around 4 months (juvenile stage) and the 8h period component has a seasonal variation. Puberty stage of this species begins near the 8th month of age in males and near the 7th month in females with 7 months of duration. With the aim to characterize the circadian motor activity rhythm during puberty in marmosets (Callithrix jacchus) the motor activity was continuous registered by actiwatches in 6 animals between 5-12 months. Since the social factor influence the behavior of this specie, behavioral observations were realized in 30 minutes windows twice/week to a general evaluation of the influence social interactions dynamic across experiment. Determination of puberty onset was done by fecal progesterone and estrogens in females, and androgens in males. From the analysis of the multiple regression test was selected a model that evaluate age and seasonal variables effect on the activity rhythm according to the higher explanation coefficient. The total activity was the only parameter influenced by age. Moreover, the activity onset was the parameter more explained by the model, and the sunrise was the factor that most influenced it. After the puberty onset, 2 dyads advanced the activity onset. The activity total decreased in 1 dyad and increased in 2 dyads. This increase may be related to the birth of infants in these families. The motor activity circadian component stabilized later in 1 dyad, coinciding with the puberty onset of these animals, while bimodality, caused by the 8 h component, was modulated by seasonality. The agonistic behavior was not evaluated due to reduced number of events. There were changes across ages in affiliative behavior of contact in 1 dyad, grooming done in 1 animal and grooming received in 2 animals. Although there is evidence of puberty effect on the activity motor rhythm, the photoperiodic fluctuations influenced the rhythm. Therefore is not possible to affirm if the puberty modulate the activity rhythm in marmosets / &#65279;A maioria dos estudos sobre o sistema de temporiza??o circadiana s?o desenvolvidos em animais adultos, infantes e idosos. A puberdade se tornou uma fase da vida pouco estudada, com exce??o dos trabalhos realizados em adolescentes humanos, que apresentam um atraso de fase no ciclo sono e vig?lia. No entanto, poucos estudos enfocam a base circadiana envolvida nesta mudan?a devido ?s dificuldades metodol?gicas. Dessa forma, um modelo animal para o estudo do ciclo sono e vig?lia na puberdade ? essencial. Em sag?is (Callithrix jacchus), um primata social, a periodicidade circadiana estabiliza em torno dos 4 meses (est?gio juvenil) e o componente ultradiano de 8 horas apresenta varia??o sazonal. A puberdade come?a pr?ximo dos 8 meses nos machos e dos 7 meses nas f?meas, com dura??o de aproximadamente 7 meses. Com o objetivo de caracterizar o ritmo de atividade motora em sag?is na puberdade foi registrada continuamente a atividade motora por act?metros em 6 animais dos 5 a 12 meses de idade. Como os fatores sociais podem influenciar os comportamentos desta esp?cie foram realizadas observa??es comportamentais em janelas de 30 minutos duas vezes/semana para uma avalia??o geral da influencia das intera??es sociais ao longo do experimento. A entrada na puberdade foi determinada a partir dos n?veis fecais de progesterona e estr?genos nas f?meas, e andr?genos nos machos. A partir da an?lise do teste de regress?o m?ltipla foi selecionado um modelo que avaliava o efeito da idade e de vari?veis sazonais sobre os par?metros do ritmo de acordo com o maior coeficiente de explica??o. O total da atividade foi o ?nico par?metro influenciado pela idade. Por outro lado, o in?cio da atividade foi o par?metro mais explicado pelo modelo, sendo o nascer do sol o fator que mais o influencia. Ap?s a entrada na puberdade, 2 d?ades iniciaram a atividade mais cedo. Em rela??o ao total da atividade, houve redu??o em 1 d?ade e aumento em 2 d?ades. Este aumento pode estar relacionado com o nascimento de filhotes nessas fam?lias. O componente circadiano da atividade motora estabilizou mais tarde em 1 d?ade, coincidindo com a entrada na puberdade desses animais. Enquanto que a bimodalidade, decorrente do componente ultradiano de 8 horas, sofreu uma modula??o sazonal. Os comportamentos agon?sticos n?o foram analisados em decorr?ncia do n?mero reduzido de eventos. Os comportamentos afiliativos de contato em 1 d?ade, de cata??o realizada em 1 animal e de cata??o recebida em 2 animais modificaram entre as idades. Embora existam evid?ncias do efeito da puberdade sobre o ritmo de atividade motora, as flutua??es fotoperi?dicas influenciaram o ritmo. Portanto, n?o ? poss?vel afirmar se a puberdade modula o ritmo de atividade motora em sag?is
