Although sex differences in verbal learning and memory have been reported in adults, much less is known about when these sex differences emerge and how they develop. In this study, 401 boys and 410 girls between the ages of 5 and 16 years were administered the California Verbal Learning Test--Children's Version. Sex differences were found at all age levels. Girls performed better than boys on all of the immediate and delayed recall trials and on the delayed recognition trial. Girls were also more likely than boys to use a semantic clustering strategy and displayed more effective long-term memory mechanisms. Boys made more intrusion errors and displayed greater vulnerability to interference between the 2 test lists. Because boys had higher mean scores on Wechsler Intelligence Scale for Children--Revised Vocabulary, the observed female superiority in verbal learning could not be attributed to sex differences in overall word knowledge.

The past decade has witnessed a rapid expansion of the Internet. This revolutionary communication network has significantly changed the way people conduct business, communicate, and live. In this report we have focused on how the Internet influences the practice of psychology as it relates to testing and assessment. The report includes topics such as test security, how technical issues may compromise test validity and reliability, and hardware issues. Special attention is paid to ethical and legal issues, with particular emphasis on implications for people with disabling conditions and culturally and linguistically diverse persons. The report also covers issues specific to areas of practice such as neuropsychology, industrialorganizational, educational, and personality. Illustrative examples of Internet test use concretize the implications of this new medium of testing and its assessment limitations and potential. The most salient conclusion from this report is that the current psychometric standards, particularly those regarding test reliability and validity, apply even though the way in which the tests are developed and used may be quite different. Still, new methods made possible by emerging technologies will push the boundaries of existing psychometric theory and it is up to psychologists to test and expand the limits of psychometrics to keep pace with these innovations.The Internet provides a tremendous opportunity for testing but with opportunity there is a corresponding need for the ethical and professional use of test results. We encourage psychologists to think creatively about how their research and practice can be improved by Internet testing. Although there are many issues that await resolution, psychologists should look forward to this new medium with excitement and enthusiasm.

We tested a hypothesis that children with sickle cell disease who are completely normal by magnetic resonance imaging can still be cognitively impaired, as predicted by a model of diffuse brain injury. Fifty-four patients with hemoglobin SS (average age 10.9 years +/- 2.9 years SD) were examined with the Wechsler Intelligence Scale for Children-III (WISC-III) and were randomly matched by age, race, and gender with healthy children from the Wechsler normative database. Patients were also imaged at 1.5 Tesla with standard imaging sequences. Among 30 patients who were normal by magnetic resonance imaging, there were substantial deficits in Wechsler Full-Scale IQ, Verbal IQ, and Performance IQ (all P < .01) compared with African-American controls. The patient Wechsler Full-Scale IQ was 12.9 points lower than that of controls and decreased as a function of age (probability = .014). The findings suggest that there is diffuse brain injury in patients and that patient deficits increase with age.

Investigated performance on the Rey Auditory Verbal Learning Test (AVLT) of 92 psychiatric and neurological patients classified as memory‐impaired (N = 45) or non‐memory‐impaired (N = 47). The groups were comparable on age and education. Relative to the non‐memory‐impaired Ss, performance of the memory‐impaired patients was significantly lower on all AVLT scores, ps < 0.01. The AVLT appears to hold promise as a quick screening measure for the clinical evaluation of patients with suspected verbal learning and memory impairments.
