A Predictor Response Process model (see Ployhart, 2006) and research findings were leveraged to formulate research questions about, and generate construct validity evidence for, a new situational judgment test (SJT) designed to measure declarative and strategic knowledge. The first question asked if SJT response instructions (i.e., 'Should Do', 'Would Do') moderated the validity of an SJT in a maximum performance context. The second question asked what the upper-bound criterion-related validity coefficient is for SJTs in talent selection contexts in which typical performance is the criterion of interest. The third question asked whether the SJT used in the present study was fair for gender and ethnic-based subgroups according to Cleary's (1968) definition of test fairness. Participants were randomly assigned to complete an SJT with either 'Should Do' or 'Would Do' response instructions and their maximum decision making performance outcomes were captured during a moderate fidelity poker simulation. The findings of this study suggested knowledge, as measured by the SJT, interacted with response instructions when predicting aggregate and average performance outcomes such that the 'Should Do' SJT had stronger criterion-related validity coefficients than the 'Would Do' version. The findings also suggested the uncorrected upper-bound criterion-related validity coefficient for SJTs in selection contexts is at least moderate to strong ([beta] = .478). Moreover, the SJT was fair according to Cleary's definition of test fairness. The implications of these findings are discussed.

This dissertation examined the relationship between personality, individual values, work values and conditions of performance. The objective of this study was to determine what motivational constructs predict a smaller differential between performance outcomes under typical conditions of performance versus maximum conditions of performance. This study examined four research questions. 1) Is there a relationship between personality traits and conditions of performance? 2) Is there a relationship between individual values and conditions of performance? 3) Is there a relationship between work values and conditions of performance? 4) Which of the overall relationships are more highly correlated? Sackett et al. (1988) characterized maximum performance as evidenced when three conditions are met: 1) there must be explicit awareness that one is being evaluated, 2) there must be awareness of and acceptance of implicit or explicit instructions to maximize effort, and 3) performance must be measured over a short enough duration that the performer's attention remains focused on achieving maximum performance. Conversely, typical performance would be characterized by situations in which individuals were not cognizant of any performance evaluation, were not attempting to perform to the best of their ability, and in which performance was monitored over an extended period of time (Sackett et al., 1988). In this study, FFM personality traits of were proposed to correlate with a differential in performance outcomes between the two conditions of performance. Similarly, individual values of conformity, stimulation, hedonism, benevolence and achievement were proposed to correlate with a similar differential in performance. A specific set of work Values drawn from the Protestant Work Ethic were also proposed to correlate with a performance differential. The results of this research suggested performance outcomes do significantly vary under each performance condition, but that the results are highly correlated (.620 with p-value < .05). Individuals who perform at a superior level under conditions of typical performance also perform at a higher level under conditions of maximum performance as well. The study did not find support for the expected relationships between personality traits, individual values or work values and outcomes between conditions of typical and maximum performance.

This thesis analyzes the physical predispositions of students from the first grade of the physical education who attended a ski course. This course took place in France. This fact is quite important for the thesis because the course took place in a higher altitude. The main aim of the thesis is to compare results of tested probands before and after the course. At first, there was an information meeting where we provided more information about the aim of this thesis and about the testing. After this meeting we went to KTVS laboratory where the first measuring happened. After that all probands and other students left for the ski course to France for a week. The accommodation was in an Alpe d´Huez center which is situated 1860 meters and the highest point of it which is 3330 meters above the sea level. Probands were practicing in very high altitude all week. In this thesis we also look at how hard it is to work in this altitude, what kind of advantages and disadvantages it might have and which danger might come up. It is also necessary to think about the process of how probands should prepare themselves not to underestimate anything. The second measuring happened after the return to the Czech Republic. It also took place in KTVS laboratory. After the measuring we started analyzing all measured data of probands. We compared this data. After that we realised what this course brought to the students. We wanted to know what happens in following parts: body composition, Wingate test, spiroergometry and spirometry. In each part we were interested in some specific parameters that are related to this topic. We included specific parameters like: body fat, muscle mass, body water, maximum performance, average performance, maximum 5 seconds performance, fatigue index, VO2max, oxygen pulse, minute respiratory volume and vigorous vital capacity.
