A missing stimulus task requires an immediate response to the omission of a regular recurrent stimulus. The task evokes a subclass of event-related potential known as omitted stimulus potential (OSP), which reflects some cognitive processes such as expectancy. The behavioral response to a missing stimulus is referred to as omitted stimulus reaction time (RT). This total RT measure is known to include cognitive and motor components. The cognitive component (premotor RT) is measured by the time from the missing stimulus until the onset of motor action. The motor RT component is measured by the time from the onset of muscle action until the completion of the response. Previous research showed that RT is faster to auditory than to visual stimuli, and that the premotor of RT to a missing auditory stimulus is correlated with the duration of an OSP. Although this observation suggests that similar cognitive processes might underlie these two measures, no research has tested this possibility. If similar cognitive processes are involved in the premotor RT and OSP duration, these two measures should be correlated in visual and somatosensory modalities, and the premotor RT to missing auditory stimuli should be fastest. This hypothesis was tested in 17 young male volunteers who performed a missing stimulus task, who were presented with trains of auditory, visual, and somatosensory stimuli and the OSP and RT measures were recorded. The results showed that premotor RT and OSP duration were consistently related, and that both measures were shorter with respect to auditory stimuli than to visual or somatosensory stimuli. This provides the first evidence that the premotor RT is related to an attribute of the OSP in all three sensory modalities.

The work is devoted to the consideration of improving the quality of teaching students the discipline “Numerical methods” through the development of the cognitive component of computational thinking based on blended learning. The article presents a methodology for the formation of computational thinking of mathematics students, based on the visualization of algorithmic design schemes and the activation of the cognitive independence of students. The characteristic of computational thinking is given, the content and structure of computational thinking are shown. It is argued that a student with such a mind is able to manifest himself in his professional field in the best possible way. The results of the application of the technique are described. To determine the level of development of the cognitive component of computational thinking, a diagnostic model has been developed based on measuring the content, operational and motivational components. It is shown that the proposed method of developing computational thinking of students, taking into account the individual characteristics of students’ thinking, meaningfully based on the theoretical and practical aspects of studying the discipline, increases the effectiveness of learning the course “Numerical methods”. The materials of the article are of practical value for teachers of mathematical disciplines who use information and telecommunication technologies in their professional activities.

Yoga is an ancient practice with Eastern roots that involves both physical postures (Asanas) and breathing techniques (Pranayamas). Yoga therapy for male sexual problems can effectively be treated through Yoga therapy, particularly with the help of Yoga poses and breathing exercises, Yoga has proven itself highly very effective in the treatment of a number of incurable and sometimes terminable diseases. Then again, Yoga's therapeutic effects are just a spin-off and supplementary. Yoga which has proved to be very effective in the treatment of many impossible and incurable diseases, the therapeutic effect of Yoga is only a by product and incidental. Problems related to sex can very well be handled with Yoga as most often these problems are more related to the mind than body. Either they are caused by lack of confidence or stress or fatigue or fear and very few times some physical cause is there. There is also a cognitive component focusing on meditation and concentration, which aids in achieving the goal of union between the self and the spiritual. Although numerous empirical studies have found a beneficial effect of Yoga on different aspects of physical and psychological functioning, claims of Yoga's beneficial effects on sexuality derive from a rich but no empirical literature. The goal of this article is to review the philosophy and forms of Yoga, to review the no empirical and (limited) empirical literatures linking Yoga with enhanced sexuality, and to propose some future research avenues focusing on Yoga as a treatment for sexual disorder.

This chapter aims at identifying the main determinants of earnings and at estimating the private returns to education in Tunisia. The private rate of return to schooling is relatively low by international standards, especially for basic education. It is argued that in addition to the limited capacity of the economy to create high-productivity jobs, institutional factors may explain the low and heterogeneous returns to education in Tunisia. The returns to schooling are found to increase with the level of education. Regional disparities in earnings and returns to higher education may be explained by the lack of economic opportunities and low exposure to market forces in many inland regions, and also by differentiated early-life conditions as well as inequality of opportunity in access to quality education. These results are used to suggest directions to strengthen the role of public policies in reducing inequality of opportunities in both schooling and earnings.

The 15-item Visual Memory Test was proposed by Rey in 1964 as a measure of malingering of visual memory. Among psychiatric patients the task has a significant cognitive component, with IQ accounting for 37% of the variance in scores ( r = .60). Any interpretation of scores on this task should be ability-based. Such ability-based norms are provided in this study of psychiatric patients ( N = 300). Use of a single cut-off score to indicate malingering or any other interpretation is inappropriate given the psychometric properties of the task. In the assessment of immediate visual memory the task has some utility, which is greatly enhanced with the use of ability-based norms.
