Reading difficulties is one of the most problems that face students when they enter universities. The main purpose of this study was to measure the reading basis of Dyslexia among undergraduate university students. The researchers performed a quantitative research method, also the non-random purposive sampling was used to collect data. The study was conducted with the participation of 414 undergraduate university students which comprising 310 males (74.88 %) and 104 (25.12%) females. After following all psychometric steps (24) (Five- Likert- Scale) for reading basis of Dyslexia was developed. The T. Test result showed a very high level of dyslexia among the participants. Moreover, males show a higher level of dyslexia than females. By using regression, this research found male participants are more dyslexics than female participants. However, this research showed that left handed and right handed has no effect on dyslexia. Also, by using one-way ANOVA, the results indicated that participants who have brain injury show a higher risk of dyslexia. Participants with left hemisphere injury showed a higher level of dyslexia compares to the participants with having an injury in the right hemisphere. In conclusion, some recommendations are presented educational sectors.

When we look at bars flashed against a moving background, we see them displaced in the direction of the upcoming motion (flash-grab illusion). It is still debated whether these motion-induced position shifts are low-level, reflexive consequences of stimulus motion or high-level compensation engaged only when the stimulus is tracked with attention. To investigate whether attention is a causal factor for this striking illusory position shift, we evaluated the flash-grab illusion in six patients with damaged attentional networks in the right hemisphere and signs of left visual neglect and six age-matched controls. With stimuli in the top, right, and bottom visual fields, neglect patients experienced the same amount of illusion as controls. However, patients showed no significant shift when the test was presented in their left hemifield, despite having equally precise judgments. Thus, paradoxically, neglect patients perceived the position of the flash more veridically in their neglected hemifield. These results suggest that impaired attentional processes can reduce the interaction between a moving background and a superimposed stationary flash, and indicate that attention is a critical factor in generating the illusory motion-induced shifts of location.

Objective To investigate somatosensory deficits in the ipsilesional wrist and hand in chronic stroke patients and correlate these deficits with contralesional sensorimotor dysfunctions, functional testing, laterality and handedness.Methods Fifty subjects (twenty-two healthy volunteers and twenty-eight stroke patients) underwent evaluation with Semmes-Weinstein monofilaments, the sensory and motor Fugl-Meyer Assessment, the Nottingham Sensory Assessment in both wrists and hands and functional tests.Results Twenty-five patients had sensory changes in the wrist and hand contralateral to the stroke, and eighteen patients (64%) had sensory deficits in the ipsilesional wrist and hand. The most significant ipsilesional sensory loss was observed in the left-handed patients. We found that the patients with brain damage in the right hemisphere had better scores for ipsilesional tactile sensation.Conclusions A reduction in ipsilesional conscious proprioception, tactile or thermal sensation was found in stroke subjects. Right hemisphere damage and right-handed subjects had better scores in ipsilesional tactile sensation.

Aesthetic preferences for photographs with the main focal content either to the left or right of the photograph's center were examined in right- and left-handed subjects. Verbal responses or manual responses were required. In one experiment with 261 introductory psychology student-subjects, left-handers more often preferred photographs with the more important part on the left (“left-geared”) than did right-handers. Exp. 2, involving 84 right-handed student subjects, showed that left-geared photographs presented on the left side were preferred more often than left-geared photographs presented on the right side, and left-geared photographs presented on the left side were more often chosen when a left-handed manual response was required. Interactions between handedness, position of the stimulus, language hemisphere, and response mode make it extremely difficult to ascertain whether the right hemisphere is really more involved in aesthetic decisions.

The article discusses the features of the manifestation of anxiety in university students and provides the main mechanisms for the correction of anxiety using art therapy. In the system of modern scientific knowledge, the phenomenon of anxiety and its impact on human development and its adaptation to the environment is one of the main issues of biology, medicine, pedagogy, and psychology. The article emphasizes the features of personality formation in adolescence, describes the main psychological mechanisms of the development of the emotional sphere. An analysis of the psychological and pedagogical literature on the use of the art therapy method as a means of correcting adolescents' anxiety levels has been performed. The results of studying the peculiarities of anxiety in university students are demonstrated. Left-handed children were found to be more anxious than right-handed. Thus, the article presents the results of a study that was carried out using a complex of appropriate psychodiagnostic techniques. The students of higher educational institutions took part in it. The article identifies the level of anxiety in the group and major differences among the subjects. It is revealed that the dynamics of the psychoemotional state is affected by the peculiarity of the left and right hemisphere asymmetries. However, with hereditary left-handedness, left-handed people are more neurotic, unlike right-handed people. It was confirmed that Art therapy, as a method of psychological and pedagogical correction, is the most effective means of psychocorrectional influence on the emotional sphere of a person. It has been determined that art therapy helps a person solve internal conflicts, deal with strong emotions, and helps to realize his feelings.

This study focused on investigating the factors that affect the entrepreneurial intention of final year undergraduate students at a South African university. It aimed to achieve the following objectives, (1) to assess the entrepreneurial intention of final year university students, (2) to investigate the effect of psychological and contextual factors on entrepreneurial intention of final year university students and (3) to examine if there is a gender difference in the effect of psychological and contextual factors on entrepreneurial intention of final year university students. The study examined the effect of psychological and contextual factors on the entrepreneurial intention of final year undergraduate students. The study used the quantitative research method with a descriptive research design. 140 students participated in the survey and data was collected through the use of self-administered questionnaire in a survey. The participants in the study were final year undergraduate business management students. The convenience sampling technique was used in the study. Data analysis included descriptive statistics and the T-test. The results indicated that business students have a high level of entrepreneurial intention. Both psychological and contextual factors positively impact on entrepreneurial intention. There is no significant gender difference. Recommendations to improve the entrepreneurial intention of students are suggested.

We previously reported decreased mean CBF between consecutive resting conditions, ascribed to habituation. Here we address the regional specificity of habituation over three consecutive flow studies. Regional CBF (rCBF) was measured in 55 adults (12 right-handed men, 12 right-handed women, 14 left-handed men, 17 left-handed women), with the 133Xe inhalation technique, during three conditions: Resting, verbal tasks (analogies), and spatial tasks (line orientation). Changes in rCBF attributable to the cognitive tasks were eliminated by correcting these values to a resting equivalent. There was a progressive decrease in mean rCBF over time, reflecting habituation. This effect differed by region, with specificity at frontal (prefrontal, inferior frontal, midfrontal, superior frontal) and inferior parietal regions. In the inferior parietal region, habituation was more marked in the left than the right hemisphere. Right-handers showed greater habituation than did left-handers. There was no sex difference in global habituation, but males showed greater left whereas females showed greater right hemispheric habituation. The results suggest that habituation to the experimental setting has measurable effects on rCBF, which are differently lateralized for men and women. These effects are superimposed on task activation and are most pronounced in regions that have been implicated in attentional processes. Thus, regional decrement in brain activity related to habituation seems to complement attentional effects, suggesting a neural network for habituation reciprocating that for attention.

Left handers and women show less anatomical brain asymmetry, larger corpus callosum and more bilateral representation of specific functions. Sensory and cognitive components of cortical auditory evoked potentials (AEF) have been shown to be asymmetric in right handed males and to be influenced by stimulus intensity. In this study the influence of sex, handedness and stimulus intensity upon AEP components is investigated under basal conditions of passive attention. 14 right handed males, 14 right handed females, 14 left handed males, and 14 left handed females were studied while lying awake and paying passive attention to auditory stimulation (series of 100 binaural clicks, duration 1 msec, rate 1/sec, at four intensities). Cz, C3 and C4 referenced to linked mastoids and right EOG were recorded. Analysis time was 400 msec, average evoked potentials were based on 100 clicks. Stimulus intensity and gender affect early sensory components (P1N1 and N1P2) at central leads, asymmetry is influenced only by handedness, right handers showing larger P1N1 amplitudes over the right hemisphere.

Two studies tested the hypothesis that the right hemisphere engages in relatively coarse semantic coding that aids high-level language tasks such as joke comprehension. Scalp-recorded event-related brain potentials (ERPs) were collected as healthy adults read probe words (CRAZY) preceded either by jokes or nonfunny controls (“Everyone had so much fun jumping into the swimming pool, we decided to put in a littlewater/platform”). Probes were related to the meaning of the jokes, but not the controls. In Experiment 1a, with central presentation, probes following jokes (related) elicited less negative ERPs 300–700 msec postonset (N400) than did probes following nonfunny controls (unrelated). This finding suggests related probes were primed by the jokes. In addition, unrelated probes elicited a larger anterior positivity 700– 900 msec than did related, as irrelevant stimuli impacted control processes invoked by task demands. In Experiment 1b, probes (CRAZY) were preceded only by sentence-final words from jokes (water) or controls (platform). No ERP effects were observed in Experiment 1b, suggesting the N400 priming effect and the anterior positivity observed in Experiment 1a reflect semantic activations at the discourse level. To assess hemispheric differences in semantic activations, in Experiment 2, ERPs were recorded as participants read probe words presented in their left and right visual fields (LVF and RVF, respectively). Probes elicited a smaller N400 component when preceded by jokes than controls. This N400 priming effect was larger with presentation to the LVF, suggesting joke-relevant information was more active in the right hemisphere. The anterior positivity was observed with RVF but not LVF presentation, suggesting an important role for the left hemisphere in controlled retrieval in language comprehension.

The effects of long-term social isolation on the content and metabolism of dopamine and serotonin systems were studied in symmetrical brain structures of BALB/c male mice. With HPLC the contents of dopamine (DA), serotonin (5-HT) and their metabolites dihydroxyphenylacetic acid (DOPAC) and 5-hydroxyindolacetic acid (5-HIAA) were measured in the cortex, hippocampus and striatum of both the right and the left hemispheres of the brain in mice reared in groups and social isolation. The isolated mice were characterized by reduced level of DA in the left striatum and elevated level of 5-HIAA and ratio 5-HIAA/5-HT in the right striatum. In the hippocampus of isolated mice, the activation of both DA-ergic and 5-HT-ergic systems was observed, that is the high level of DA and DOPAC in the left hippocampus and the elevated level of 5-HT in both hemispheres and of 5-HIAA in the right hippocampus were registered. On the other hand, the reduction of both DA-ergic and 5-HT-ergic systems activity was shown to be in the right hemisphere. The decreased concentration of DOPAC and ratio DOPAC/DA in the right cortex were observed as well. As to 5-HT-ergic system, the reduced level of 5-HT in the both cortex of the hemispheres as well as 5-HIAA in the right hemisphere of isolated mice was determined. The phenomenon of interhemispheric asymmetry was revealed in the hippocampus only, which was characterized by the increased DA-ergic activity in the left hippocampus but not in the striatum and the cortex.

The article depicts the peculiarities of St. Vladimir University students’ nutrition in the years 1834-1863. The main aim of the research to show how nutrition differentiated among students community and how different types of diet influenced everyday life of them. That’s why the types of nutrition of two main students’ groups (who were educated and maintained by the state and students who studied at their own expense) are analyzed in the article. Special attention is paid to the question of the diet, the peculiarities of the regime, organization, and nutrition value of products for students. For example, budget students had a fixed schedule of eating. Their breakfast started at 7 am. It was only a small loaf and a cup of tea. The students had completely the same dinner at 6 or 7 pm. The main portion of the food they received for a lunch. Typical lunch included primarily liquid food (soup with beetroots, beans, peas, meat or fish), then students received the main dish. Usually, it was roasted meat or fish with potatoes or other side dishes. The university administration hired special servants for questions connected with budget students’ nutrition. The main role of supplying food for students’ table played a provisor. He also hired all staff (cooks, bakers, lackeys), who cooked and served food for students. Presence of servants was a special reason to approach students to noble culture because it was thought that the main ideal for student behavior was connected with noble traditions. It was defined that budget students had well-organized nutrition system, nevertheless, the quality of products and quantity of food weren’t at a high level. That’s why students often complain about tasteless, little nutritious food. Calculation count of calories in budget students’ food showed that they hadn’t received the right amount of calories. From time to time the university administration tried to improve students’ nutrition, but it hadn’t worked because they couldn’t raise the level of funding. At the result, in 1858 the university administration stopped to supply students with food and started to pay scholarships. After this decision, the specificity of nutrition for all students became the same. The majority of students in 1863 had problems with nutrition this shows statistics from that year. The author points out that except typical diet students had a special hospital and disciplinary cell diets. If the hospital diet was pretty much the same as the normal meal, the disciplinary cell diet included only a piece of bread and water. It is also important to emphasize that students had to follow all religious rules. That’s why they kept all fasts. During that fasting time eating meat and fats were forbidden and students’ nutrition becomes worse. At the same time, a lot of students who studied at their own expense had another system of nutrition. For example, rich students had perfect food and they visited restaurants and had their own cooks and lackeys, next to them it was easy to find a student who didn’t eat for a few days. Very often the meal was included in a price of apartment rent or students cooked by themselves. Typical price for an apartment with nutrition started from 3-4 rubles per month, in comparing lunch in ordinary Kyiv hotel cost around 10 rubles per month. Sometimes parents of students sent them food because prices in Kyiv were higher than in the region. It was also common among students to feed on in special canteen organized by Kyivan hostess. Usually, it was an old lady who served a cheap meal and sometimes students could get some food in debt. Nevertheless, a lot of students who studies at their own expanse suffered from pure nutrition. Very often bad food was the reason for bad results in studying. However, the reason for bad nutrition helped students to unite to overcome life's difficulties. It was common among students to settle together and share all food. Sometimes students organized parties where they shared all meals, this activity contributed to the merger of the student corporation.
