Perceptual Impact of Two Syllabification Procedures in English
Šturm, Pavel ; Volín, Jan (advisor) ; Skarnitzl, Radek (referee)
The subject of the thesis is the determination of syllable boundaries in English with respect to its perceptual relevance. The hypothesis is based on two different theoretical conceptions. The Maximum Onset Principle (MOP), a traditional approach widespread among linguists, assigns intervocalic consonants to neighbouring syllables in such a way that the longest possible onsets are created in the syllables that follow. An alternative view, advocated by John Wells, advises to utilize more complex parameters, such as morphological structure, prosodic structure or, most importantly, the allophonic realization of phonemes as determined by position within the syllable. A word monitoring experiment measuring reaction times, in which listeners pressed a key if they heard a given word in the auditory stimulus, yielded data about listeners' performance in two conditions: in one the items were divided into syllables according to the MOP, in the other according to Wells. The latter was associated with faster reactions, which might be interpreted as cognitively less strenuous. However, the difference between the two conditions was not robust, mainly because of the limited number of listeners.

Physical profile of judo athletes and its changes due to body weight reduction
Coufalová, Klára ; Heller, Jan (advisor) ; Harsa, Pavel (referee) ; Vomela, Jindřich (referee)
Title: Physical profile of judo athletes and its changes due to body weight reduction Aim of work: The aim of this study was to determine the effect of intensive pre-competitive body weight reduction on body composition, anthropometric parameters, postural stability, reaction time, maximal isometric muscle strength and biochemical parameters in the blood of elite judo athletes. Methods: The work compares the results of laboratory testing at the beginning and at the end of body weight reduction. Nine male judo athletes (age 22.3 ± 2.4 years) from the Czech national team participated in the research. For laboratory testing we used bioelectrical impedance analyser InBody 720, anthropometric equipment, pressure plate FootScan, dynamometer and apparatus for measuring reaction times of Biomedical laboratory UK FTVS and equipment for the collection of capillary and venous blood. We created a survey to gather more information about pre-competitive weight loss, attended by 53 competitors (37 men and 16 women, mean age 23.7 ± 3.2 years) who practise judo, wrestling Greco-Roman and freestyle, boxing, kickboxing, thaibox, taekwondo or karate. Results: We found a statistically significant (p<0.01) reduction of body weight, average weight loss was 4.6 % (on average 3.4 ± 1.6 kg). This reduction was reflected in...

Analysis of the Reaction Time of a Driver Influenced by Selected Distracting Stimuli
Černohorská, Magda ; Semela, Marek (referee) ; Bucsuházy, Kateřina (advisor)
The diploma thesis deals with the analyses of food consumption influence on driver´s perception reaction time. It describes the food and drink consumption while driving, factors influencing driver´s performance, activities disturbing the driver, foreign researches and studies aimed at distracting stimuli. Practical part of the thesis is focused on driving tests of chosen driver of certain age group in current traffic, interpretation and evaluation of reaction times while driving with no distracting stimuli comparing to driving influenced by food consumption. All the data are concluded in the summary where it´s confirmed that reaction times are significantly prolonged when drivers have a snack while driving a vehicle.

Characteristics of Old-Age Drivers in Terms of Road Traffic Safety
Lukesová, Dominika ; Drahotský, Ivo (referee) ; Schmeidler, Karel (advisor)
The aim of this work is to evaluate current procedures and to refine assessment of impact connected to the drivers' age and traffic accidents. The theoretical part describes senior drivers, traffic accident rate of seniors and decreased ability to drive influenced by age. The practical part is case report of traffic accidents caused by senior drivers, measuring reaction time and the evaluation of these measurements. I have developed some proposals for seniors to prevent the risk of the occurrence of traffic accidents.

THE MEASUREMENT OF THE REACTION TIME ON THE AUDITORY STIMULI CONCERNING THE PLAYERS OF GOALBALL.
Hakenová, Pavlína ; Hendl, Jan (advisor) ; Kovařovic, Karel (referee)
Title: THE MEASUREMENT OF THE REACTION TIME ON THE AUDITORY STIMULI CONCERNING THE PLAYERS OF GOALBALL. Objectives: The main objective of this paper is the measurement of the reaction time on the auditory stimuli concerning the players of goalball. Another objective is to analyze acquired data and to compare measured values with those measured within the healthy population. The last objective is to compare health groups B1, B2, B3 and productive groups within the premiere league and the players of the goalball representation. Methods: Measurement and analyzing of the acquired data's methods were used in this paper. The reactometer, earphones and the computer with the software that enables to automatically analyze measured data were the main tools used. Acquired data were displayed in the measured values' chart and within the graph on the axis displaying the course of measurement as well. The analyzing method was used to analyze the individual measured outcomes of the reaction time. Results: The final part of this work was based on the three hypotheses. The first hypothesis assumed that the goalball players' reaction speed is faster than within the healthy population. This hypothesis was confirmed. According to measured outcome, from the sample of the healthy population there was not a person who...

The impact analysis of the technical devices used by the driver on the reaction time
Kubánek, Ondřej ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
This master‘s thesis analyzes the impact of the use of technical equipment for the driver reaction time. There are described the legal requirements for the use of technical devices by the driver in the vehicle. There are analyzed the types of technical devices used by drivers and mainly discussed the issue of drivers' reaction times. They assessed factors affecting reaction time, ways of measuring the reaction time and the type of reaction times. They discussed earlier research from the beginning of the measurement of reaction times to the latest research, dealing with the measurement of reaction times when using a mobile phone. The practical part is devoted to perform road tests on a sample of drivers and evaluate their reaction times during normal driving and during a call. The measured and evaluated data are commented with respect to the benefits of expert activities in the field of transport.

Influence of the reaction time on neuronal response amplitude after the uncommon stimuli in fMRI images
Klimeš, Filip ; Bartoň, Marek (referee) ; Lamoš, Martin (advisor)
The goal of my bachelor’s thesis is to provide basic idea of the functional magnetic resonance imaging. The theoretical part deals with general principles, methods of measurement and analysis of fMRI data. The partial and also key objective is to design ways of modelling reaction time within the concept of general linear model. The goal of the practical part was to become familiar with SPM toolbox and then to implement designed ways on group data. The implementation was carried out at two levels: preprocessing and analysis of measured data. Preprocessed data were subjected to the first level analysis and second level analysis. Next aim is to evaluate the results of both analysis and thus different approaches to the modelling of reaction time and its influence on neuronal response amplitude after uncommon stimuli in functional magnetic resonance images.

Device for measuring of the reaction time
Bohuš, Michal ; Kolářová, Jana (referee) ; Balogh, Jaroslav (advisor)
The aim of this bachelor thesis was become acquainted with human reaction time,its measurements and use. Part of the project was to build a device that measures reaction time of audio-visual stimulus. The device consists of stimulating and controlling parts. Audio-visual stimuli are scanned and controlled by microcontroler ATmega 16. Based on the obtained reaction time evaluate reaction time of measured entity.
