“…This is consistent with the literature, which has shown practice effects to be present [Taub, 1973;Otto et al, 1992;Dikmen et al, 1999;Wilson et al, 2000;Farahat et al, 2003]. The orbitofrontal and mid-ventrolateral frontal cortex are very prominent in neuroanatomical studies using digit span tasks [Owen, 2000].…”

Extremely low frequency (ELF, <300 Hz) magnetic fields (MF) have been reported to modulate cognitive performance in humans. However, little research exists with MF exposures comparable to the highest levels experienced in occupations like power line workers and industrial welders. This research aims to evaluate the impact of a 60 Hz, 3 mT MF on human cognitive performance. Ninety-nine participants completed the double-blind protocol, performing a selection of psychometric tests under two consecutive MF exposure conditions dictated by assignment to one of three groups (sham/sham, MF exposure/sham, or sham/MF exposure). Data were analyzed using a 3 × 2 mixed model analysis of variance. Performance between repetitions improved in 11 of 15 psychometric parameters (practice effect). A significant interaction effect on the digit span forward test (F = 5.21, P < 0.05) revealed an absence of practice effects for both exposure groups but not the control group. This memory test indicates MF-induced abolition of the improvement associated with practice. Overall, this study does not establish any clear MF effect on human cognition. It is speculated that an ELF MF may interfere with the neuropsychological processes responsible for this short-term learning effect supported by brain synaptic plasticity.

“…ICCs were used because they provide a better measurement of true agreement than simple Pearson's correlations (for discussion see e.g. Farahat et al, 2003). The ICC depends on inter-subject and intrasubject variability.…”

“…Rohlman, Anger, and colleagues at the Oregon Health Sciences University (Farahat, Rohlman, Storzbach, Ammerman, & Anger, 2003;Rohlman et al, 2003) launched a program of research designed to accomplish testing in a broad array of cultures. This group developed a computerized battery of tests to assess multiple functional domains and examined the tests' reliability, sensitivity, and validity.…”

The heightened public awareness that environmental contaminants can act on the nervous system and have effects that appear in behavior presents a major challenge to behavioral scientists in all areas. They are being asked to conduct both hazard assessment (are there neurobehavioral effects of some chemical at any dose?) and risk assessment (what is the risk to a population at a specific level of exposure?) for behavioral effects that are not always well understood. The heavy metal lead provides an excellent example. Concern over lead poisoning lies in claims that it lowers scores on IQ tests, retards academic performance, and results in disruptive and even criminal behavior. The problems posed are daunting: How easy is it to detect a 5-point drop in scores on IQ tests? Can scientists predict these effects from experimental models using laboratory animals? Can they identify behavioral and neural mechanisms that account for these effects? What economic costs are incurred if the average IQ drops a few points, and how does this cost compare with that of reducing lead in the environment?These concerns are reflected in policymaking. Federal legislation and regulation of toxic substances specifically include behavior, including schedule-controlled operant behavior, as a regulatory endpoint (Tilson, 1990). The inclusion of nervous system damage in general, and its behavioral manifestations in particular, represents a sea change in public concern over unintended exposure to chemicals. Where cancer has been (and still is) a significant concern, the recognition that adverse behavioral effects follow certain types of chemical exposure is increasing. These effects carry over into a large number of domains. Environmental contaminants, even at very low exposure levels, contribute to disorders across the life span, including developmental disabilities and the hastening of age-related impairments. Behavioral scientists' understanding of how this happens not only has public policy implications but can also inform them about the behavior and neurobiology surrounding these disorders.
