Svobodová, Libuše ; Vančata, Václav (advisor) ; Ehler, Edvard (referee)
TITLE: Left-handedness and its acceptance in contemporary education system and families AUTHOR: Libuše Svobodová DEPARTMENT: Department of Biology and Environmental Studies SUPERVISOR: doc. RNDr. Václav Vančata, CSc. ABSTRACT: The diploma thesis entitled Left-handedness and its acceptance in contemporary education system and families follows up and complements the bachelor thesis entitled The issue of left- handedness in the development of children and youth - history, present and perspectives. The first and second chapters of the theoretical part of the diploma thesis focus more deeply on the characteristics of left-handed writing styles, advantages and disadvantages of left-handed writing, suitable writing aids, classroom order, organization of work environment and writing methodology. The third chapter is devoted to laterality tests with a focus on the upper limb, lower limb, eye and ear, test tasks, their conditions and evaluation. The last fourth chapter of the theoretical part deals with the central nervous system, more precisely the brain and its asymmetric anatomy, function, control of upper limb movements and motor development of the upper limb. The practical part of the diploma thesis consists of five researches. The first research verifies the occurrence of left-handers in primary schools and...

Evolutionary aspects of (epi)genetic determination of laterality with a special focus on upper limb
Holoubková, Tereza ; Daňková, Pavlína (advisor) ; Struška, Michal (referee)
Handedness is one of the most distinct asymmetries of the human body. There is approximately 90 % of right-handers in the population, which is the strongest bias in handedness among all primates. Handedness is connected with lateralization of brain for language and is determined both genetically and by the environment. Genetic determination of the handedness has not been yet figured out, although there are many candidate genes and regions. In addition to candidate genes, the genetic determination is shaped by the epigenetic mechanisms and the role of testosterone. Handedness occurred alongside the beginning of the human population development, approximately in the Middle Pleistocene, with the same percentage of left-handers as today. Handedness polymorphism is maintained in the population based on the frequency-dependent model because of the advantages and disadvantages associated with left-handedness.

Forced laterality changes in childhood and their influence on the overall development of personality
Ťupová, Tereza ; Klenková, Jiřina (advisor) ; Kopečný, Petr (referee)
The diploma thesis deals with laterality, the research presents analysis of laterality of six adult people with forced changes in laterality. Then it describes the development of laterality and its types, degrees, types and diagnostics. There is also a historical approach to the left-hand side from the Stone Age to the present. The work focuses on forced changes in laterality in childhood and their influence on the overall development of personality. Six adult respondents, three men and three women aged thirty- eight to seventy-two years were tested for qualitative research. The effects of laterality change were observed in speech, psyche, state of laterality, reading and written speech. The aim of the work was to describe the difficulties that may arise as a result of a forced change in laterality, to find out whether the respondents have to face and to discover their possible survival to adulthood. For all respondents, the laterality and type determined by the test was tested, which was a partial goal. For all respondents, during the interviews, problems related to forced changes in laterality in childhood were manifested or discussed.

Hygienic and Working Habits of Left-handed Pupils at Primary School
KOLÁŘOVÁ, Lucie
The diploma thesis deals with the hygienic and working habits of left-handed pupils at the first level of elementary schools. The thesis is divided into two main parts, theoretical and research. The theoretical part of the thesis deals with basic information about laterality, brain hemispheres and school maturity. The main focus is on leftist and writing, where we focus on preparation for writing and individual hygiene and working habits of pupils. Problems of written speech and famous leftists are also mentioned. The research part is focused on the survey of the level of hygienic and working habits of primary school pupils. The research was conducted in the form of observations. The obtained results are graphically processed and interpreted. In conclusion, there is a recommendation for working with left-handers in practice.

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.

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.
