Luria's tapping test (tap once when E taps twice, tap twice when E taps once) was administered to 160 children (80 males, 80 females) between 3 1/2 to 7 years old. Older children were faster and more accurate than younger children, with most of the improvement occurring by the age of 6. All children tested demonstrated understanding of the instructions during the pretest, and most started out performing well, but younger subjects could not sustain this. Over the 16 trials, percentage of correct responses decreased, especially among younger subjects. Performance here was compared with performance on the day-night Stroop-like task. The most common error on both tasks was to comply with only one of the two rules. Other errors included tapping many times regardless of what the experimenter did and doing the same thing as the experimenter, rather than the opposite. It is suggested that the tapping task requires both the ability to hold two rules in mind and the ability to inhibit a strong response tendency, that these abilities improve between 3-6 years of age, and that this improvement may reflect important changes within frontal cortex during this period of life.
PURPOSE: To examine the relationship between the objective premedical credentials and performances on Step 2 on the United States Medical Licensing Examination (USMLE) of 480 students in three classes at the Virginia Commonwealth University Medical College of Virginia School of Medicine. The purpose of the study was to seek those selection criteria that might best predict performance on an examination designed to assess problem-solving skills, the essence of clinical medicine. METHOD: Premedical data from two classes (1193, 1994) were analyzed, and a regression equation was used to calculate theoretical USMLE Step 2 scores for the students in the class of 1995, who had not yet taken this examination. The premedical variables were scores on the verbal and math section on the Scholastic Aptitude Test (SAT), scores on the six sections of the pre-1991 Medical College Admission Test (MCAT), grade-point average (GPA) in science courses required of premedical students, and undergraduate major. Once the class of 1995 had taken the USMLE Step 2, the equation was cross validated, and the theoretical and actual scores of the class of 1995 were correlated. RESULTS: The correlation between theoretical and actual scores was r = .443. In the analysis for the classes of 1993 and 1994, the single variables most highly predictive of USMLE Step 2 performance were scores on the verbal section of the SAT (r = .317) and the Skills Analysis: Reading section of the MCAT (r = .331). However, the MCAT scores were excluded from the final regression analysis because of the pre-1991 MCAT cannot be useful in predicting the performances of present medical school applicants. The resulting regression equation (using the SAT verbal section and premedical GPA) was able to account for 21.2% of the variance for the class of 1995. CONCLUSION: The use of the verbal section of the SAT as a predictive factor is unique. It is significant that this variable was strongly related to premedical GPA, suggesting that high verbal aptitude serves one well, even when coping with complex scientific concepts.
The diagnosis and management of many oculomotor anomalies is within the domain of optometry. Thus, a thorough understanding of these systems and their relation to reading performance is vital. Efficient reading requires accurate eye movements and continuous integration of the information obtained from each fixation by the brain. A relation between oculomotor efficiency and reading skill has been shown in the literature. Frequently, these visual difficulties can be treated successfully with vision therapy.
