Role of laterality in agonistic behaviour of red deer II
Jirsová, Adéla ; Bartoš, Luděk (advisor) ; Kouba, Marek (referee)
The theoretical part of this diploma thesis deals with the role of brain laterality of red deer (Cervus elaphus) in agonistic behaviour. Therefore, the largest part of the review of published scientific outcome is devoted to the agonistic behaviour, namely it focuses on the fights between males during the autumn rut. Battles are strictly ritualized and males adhere to strict rules. The role of laterality in animals is being recently studied and the outcomes so far indicates that, particularly in agonistic interactions the laterality may play a significant role. Brain lateralization is simply a preference for one or the other hemisphere in certain activities. The main topic of this thesis is how laterality affects combat of red deer.
The research part took place in a deer-park Zátoň where the duels between stags in rut were recorded. We also used videos from farms Podlesko and Žalany and a deer-park Milešov. These records were processed in the program Noldus Observes, with emphasis placed on the facts which deer was the initiator of the fight and his position to opponent, or with which eye the opponent was perceived at the beginning, but also during the fight. Data were statistically evaluated in SAS software (version 9.4., SAS Institute Inc.). We observed a strong tendency that the winner also initiates the interaction. Chance, that the winner will be the initiator, was compared to recipient 15 times higher. Initiator estimates his option in the battle to win, so he does not let the duel quit before it comes to physical confrontation. Regardless of the character of the behaviour initiator approached his rival more likely on right eye. There was statistically significant demonstrated initiator access to the recipient from the right side in parallel walk as well as in direct physical engagement. As stags train fights during the whole year, so even in the rut are information processed by the left hemisphere, which controls the routine affairs. We can say, that the deer fights during the rut are so frequent, when applies the routine of using antlers as a weapons and therefore we observe right side preference.

Graphomotorics of preschool children and its development before entering elementary school.
KOCOVÁ, Ilona
This bachelor thesis focuses on the level of graphic motoric skills of children in the pre-school age and elimination of difficulties in this area. The thesis consists of two parts theoretical and practical. The theoretical part characterizes pre-school child, explains the concept of motoric skills and laterality. It is engaged in the development of drawing by pre-school children and by the proper grip of writing instruments including exercise and proper fixation of position at working desk. The second practical part describes the process of graphomotorics course and includes case studies of children and analysis of their drawings and fictitious fonts before and after graphomotorics course.

The Problems in Writing of Left-handed Pupils
HERWIGOVÁ, Kateřina
The thesis "The Problems in Writing of Left-handed Pupils" is focused on the dificulties in the first steps of writing of left-handed children in primary schools. The thesis is divided into two parts. In the theoretic part we deal with the laterality and the left-handness in general. Further we deal with the development of left-handness in the history and nowadays and first of all with the development of motor skills of the left-handed children in the preschool age. The next aim is to chart the difficulties in the preschool period and the potencional problems in writing. The main part of our thesis is focused on the correct methodological help with writing in the first class in primary schools. The other part of our thesis is practical part. In this part we focus on the analysis of the writing edacation for the left-handed pupils in the first classes in the schools in Central Bohemian Region. We studied the quantity of the left-handed boys and the left-handed girls, the correct holding of writing tools, the slope of paper, the slope of letters, the correct sitting, the using of ergonomic tools and the using of pens or pencils.

Laterality and wages: Is there a price premium for the left-handers?
Jakubcová, Klára ; Komrska, Martin (advisor) ; Babin, Jan (referee)
This thesis empirically examines the influence of laterality on wages in the Czech Republic. I gathered cross-sectional data using a questionnaire. In general there is an expectation of the left-handers to be underpaid. The reason for this is the unavailability of specific tools adapted to be used by the left-handed workers which results in lower productivity of work. The first tested hypothesis argues that left-handed men achieve wage premium due to better creative abilities. The second hypothesis suggests that the wages of left-handed women are penalized compared to those of right-handed women. To test the hypotheses the process of estimating regression equations by the method of least squares was used. Neither hypothesis was confirmed using my basic models. On the contrary, the results suggest that the left-handers should have in average 6,6 % lower wages than right-handers and left-handed women about 4 % higher wages than the right-handed women. However, the statistical significance of laterality variables was not confirmed in the basic models. After splitting the dataset according to the highest education achieved the results were as follows: The left-handed male workers with the university degree have 14 % higher hourly wage than the right-handed workers with same attributes. The left-handed male workers with secondary education and lower degree of education have 43 % lower hourly wage than the right-handed (There was no influence observed in case of left-handed women).

Laterality as a pedagogical issue
OBSELKOVÁ, Gabriela
The bachelor thesis is focused on pre school and early school children education, considering their laterality. The work investigates activities that are mostly affected by children's laterality and attempts to determine where the biggest laterality concerning pedagogical issue lies. Theoretical part of this thesis brings basic information about the laterality issue and education. The concept of laterality is explained first in terms of etymology and then the division of laterality is discussed. Further, there is a description of mutual relationship between laterality and cerebral dominance, evolution of laterality and the process of its diagnosis, including the quantification of the right-handedness quotient and assessment of particular kinds, degrees and types of laterality. The work also introduces the term right-handed society, possible reasons of its creation and its historical evolution. Further, the work focuses on pre-school and early school children education, therefore a characteristic of the particular period in child development is defined and then a right- and left-handed children education itself is described. In relation with the thesis' aim, students writing education is discussed, along with its principles, possible used methods, particular education phases and also the new font Comenia Script is mentioned together with differences in writing education at alternative schools. The work also describes the specifics of left-hand writing. Goal of the empiric part of the thesis was to find out the way upbringing, education and methodology of graphomotorics development in child writing is implemented in the early school years, taking into account their laterality. Three questions were defined for this research. Question no. 1: How is the graphomotorics development and right- and left-handed child writing education implemented during pre-school and early school years? Q. no. 2: What part do the teachers in pre-schools and primary school attribute to the methodology and didactics of graphomotoric development? Q. no. 3: What are the results of right- and left-handed pupils during initial writing? During the practical part of the thesis, a qualitative research strategy was used. In order to obtain necessary data, a laterality test, structured observation technique and half-standardized interview were used. The research was held in the school year 2013/2014 in three schools in the city of Světlá nad Sázavou. There were 54 pre-school children, 51 primary school pupils and 7 teachers participating in the research. Results of this work bring processed data from all the techniques used in the research and give the information about functional laterality of respondents and also about the way left- and right-handed children education is conducted during the pre school and early school age. The results show that the number of right-handed exceeds the number of left-handed and also an experts´ opinion on the children laterality development was confirmed. The research also brings knowledge about the importance of children's and pupils' work habits education, improving writing skills, which is not yet fixed even in the first grade pupils. Finally, the research also describes the process of writing education in first grade in the selected primary schools, which differentiates most in the way of left-handed education, where 2 teachers accept the so called top way of writing and one teacher encourages pupils to write only using the bottom way of writing. According to interviews with teachers, right- and left-handed pupils have the same results in writing in all of the classes. Interviews also bring the teachers´ opinions on the new Comenia Script font. This thesis brings findings about right- and left-handed children and pupils´ education in selected pre-schools and primary schools. Results can be used as topics for discussions centered around methodology and didactics of writing education considering pupils' laterality.

The issue of left-handedness
GROBHEISEROVÁ, Petra
The theses The issue of left-handedness focuses on left-handedness at its complexity. The theoretical part is focused on laterality and the left-handedness in general, the place of left-handed people in society and the changing view on laterality during times. It focuses on the differences between left and right-handed people and points out possible difficulties the left-handed might face. At the end I dealt with testing laterality and focused on possible ways to guide left-handed pupils. The practical research part is based on finding out the number of left-handed pupils in 1st grades on schools in the Karlovy Vary region. I farther focused on how aware of the lefthanded pupils problems the teachers are and how they guide them. The research took part in 16 randomly picked schools.

Laterality and other factors affecting wages in PR agencies
Borovská, Radka ; Houdek, Petr (advisor) ; Brožová, Dagmar (referee)
Left-handed persons are expected to earn less as a penalty for their unstandard hand orientation. However, it was discovered, that the reality is opposite (Denny, O'Sullivan 2007). This thesis examines on a sample of employees of PR agencies in the Czech republic success of left-handed persons in work according to their wage, frequency of promotions and working position. There was no correlation with laterality observed. Another tested part is their alcohol consumption and frequency of their visits in pubs, which should positively influence their wages, if their consumption is moderate (Peters, Stringham 2006). However, it was discovered, that wages are influenced by sex, but not by laterality, even alcohol consumption does not influence wages. Smoking influence amount of wages in a negative way (Levine et al. 1997) and is more common between left-handed persons (Ernest Harburg, Anna Feldstein, James Papsdorf 1978). There is a relationship between laterality and smoking, but there is no effect of smoking on wages at all.
