With regard to visual activity, four types of eye movements—fixations, saccades, smooth pursuits and blinks—can be distinguished. Fixations—the number and distribution, total fixation time or average fixation duration are among the most common measures. The capabilities of this research method also allow the determination of scanpaths that track gaze on the image as well as heat- and focus maps, which visually represent points of gaze focus. A key concept in eye-tracking that allows for more in-depth analysis is areas of interest (AOI)—measures can then be taken for selected parts of the visual stimulus. On the other hand, the area of gaze outside the scope of analysis is called white space. The software allows for comparisons of static and non-static stimuli and provides a choice of template, dataset, metrics or data format. In conducting eye-tracking research, proper calibration is crucial, which means that the participant’s gaze should be adjusted to the internal model of the eye-tracking software. In addition, attention should be paid to such aspects as time and spatial control. The exposure time for each participant should be identical. The testing space should be well-lit and at a comfortable temperature.","PeriodicalId":426942,"journal":{"name":"Experimental design and biometric research.

Conducting experiments can take place in laboratory conditions, but also in natural environments. The main objective of an experiment is always to test what the researcher actually wants and to obtain results that can be generalised to the entire population. In other words, planning experiments requires considering many aspects related to their internal and external validity. The key aspect that needs to be considered in conducting experiments is proper problem defining, as well as the concepts of causality, manipulation or null and alternative hypotheses. It is also worth bearing in mind that in social sciences, when engaging participants in research, caution must be exercised. Depending on whether each participant of the experiment is exposed to all conditions or different people test different ones, the classification of experiments is distinguished into within-subjects and between- subjects design. In this chapter, the most commonly used experimental designs in this division are presented. However, the experimental method offers more complex schemes such as randomised block design or Latin square design. Finally, the obtained findings should be properly presented—in the form of a report following APA standards.","PeriodicalId":426942,"journal":{"name":"Experimental design and biometric research.

It is believed that the excretion of sweat, which is regulated by the nervous system acting independently of human will, is an indicator of a person’s emotional arousal as a result of specific stimuli. Hence, the electrodermal reaction can be used in diagnosing emotional arousal caused by, e.g. specific products, advertisements or elements of the in-store space. Electrical activity of the skin is caused by two types of stimuli: sustained and one-off. Sustained stimuli have a continuous effect on the body over a relatively long period of time. On the other hand, one-off stimuli have a relatively strong and very short-lasting effect. This type is defined as novel, unexpected, significant or aversive. Electrodermal activity is measured on the skin surface (Strelau, 2006). Generally speaking, the measurement of electrodermal activity is one of the biometric measurements. Biometrics is a universal term that represents measurements of the body’s physiological responses—not directly of the brain—to external stimuli that are felt through the senses (Pradeep, 2010; Berčík & Rybanská, 2017). The electrodermal method allows to measure either electrical resistance or its inverse, i.e. the electrical conductivity of the skin. These measurements are carried out while a small current flows through the skin from an external source. Electrodermal activity measurement is performed with the use of special electrodes, electrode gels and recording devices. The available equipment for the analysis of electordermal activity is characterised by relatively low cost (compared to other devices for physiological measurements)of purchase and operation. Moreover, the electrodermal activity measurement is non-invasive and carries no risk to the health or life of the test subjects.","PeriodicalId":426942,"journal":{"name":"Experimental design and biometric research.
