Relationships among hand preference, nonverbal intelligence, and the monocular shifts of binocular focal point were studied in 33 men and 12 women university mathematics students. Ocular dominance was assessed with the Miles test. The monocular shift of binocular focal point for each eye was assessed with a modified Miles test. Hand preference was assessed on the Edinburg Handedness Inventory. Nonverbal intelligence was assessed with Cattell's Culture Fair Intelligence Test. In a prior study, the percentage of left-eye preference had been reported to be greater for mathematics students than for nonmathematics students. In the present study there were positive correlations between hand preference and the sum of the monocular shifts of two eyes. In addition, there was a negative correlation between nonverbal intelligence and the sum of the monocular shifts of two eyes. As these resultssuggest that the sum of the monocular shifts of two eyes may be related to mathematical ability and nonverbal intelligence, further research with a larger sample including non-mathematics students is needed.

In this present study, it was aimed to investigate whether the hierarchical structure of mathematics emerged in university students' minds or not, considering the concepts of limit, continuity derivative and integral from the perspective of students in the department of secondary school mathematics teacher training and the department of mathematics in the faculty of science and letters. The study, designed with the case study methodology, was carried out with 100 participants. Data were collected with the research group via a survey form including totally five questions; one of which is conceptual the other four are operational and analysed with the descriptive analysis. From the results of the research, it was found out that the participants could not learn the concepts of limit-continuity-derivative-integral conceptually and could not constitute the hierarchical structures among these concepts in their minds. Nevertheless, it was determined that the participants learned the procedural knowledge of each concept independent from the other. From these results, it can be recommended that placing activities emphasizing on the relationships among the concepts in teaching the concepts should be applied more.

Relations between the hearing durations of right and left ears and points on the introductory examination for entrance to the Science School of Ataturk University in Erzurum were investigated in 31 male and 13 female students. The hearing duration of the left ear was significantly associated with the scores of the examination for the university entrance, the hearing duration for the right ear being not significantly related to the examination scores. The results suggest that the right brain would be beneficial for the students' achievements in science.

In this study, we aimed to re-examine sex-related differences in mathematics anxiety and to investigate the effects of two different programs associated with mathematics education applied in Turkish universities on mathematics anxiety. Mathematics anxiety scores were assessed in 221 male and 142 female students, 238 in the education faculty and 125 in the science faculty. There were no sex-related mean differences for mathematics anxiety scores, and scores were not related to faculty program. The lower mean mathematics performance on the university entry examination of the students of science faculty may be associated with the mathematics anxiety.
