There have been two studies of the neurodevelop-mental effects of cocaine during the first 48 hours of life. In the first, 23 cocaine-exposed and 29 non-exposed infants were prospectively assessed within the first 48 hours of life infant meconium was used to detect cocaine and the BNBA Scale was used for clinical assessment (214). One-third of the cocaine-exposed neonates were born to women who denied cocaine use. In six of the seven clusters assessed, cocaine-exposed infants fared badly compared with control infants. The cocaine-exposed infants had poor autonomic stability and there was a dose-response relation between meconium cocaine concentration and poor performance in relation to orientation and so-called regulation of state, which refers to how the infant responds when aroused. The authors concluded that cocaine exposure is independently related to poor behavioral performance in areas that are central to optimal infant development. They emphasized the value of the identification and quantification of cocaine in infants. 

From the 1960s onward, there was a greater interest in psychological issues, dominated by the concept of the human as a single-channel processor of information. This stimulated research into a number of areas. Studies of mental workload were concerned with the ability of humans to cope with extremely high levels of information in situations such as air traffic control. Vigilance studies, which focused on the human s role in situations with very low levels of stimulation such as radar monitoring, represented the other extreme of human performance that was considered. 

Although there are several ethical concerns with biobanks and other large-scale research repositories (Rothstein, 2002), the most important issue is informed consent. Participants in research involving human subjects must be advised of the intended research to be performed with their specimens. With biobanks, however, the future research uses of the samples are unknown at the time of collection. It would be infeasible to contact each of the donors to obtain consent every time a new research use is contemplated, yet IRBs are reluctant to approve the use of blanket consent for unspecified uses. One way to avoid this problem is for prospective sample donors to be given a menu of possible uses of their samples. Such a list might include research in mental health, HIV/AIDS, cancer, cardiovascular disease, or other areas. The donors would then have the opportunity to approve the use of their specimens for all or some of the listed uses. Other disclosures necessary to obtain informed consent include the financial interests of the biobank and researchers, whether individuals may elect to be notified of research findings, and whether it is possible for an individual to withdraw his or her sample from the bank (Rothstein, 2002). 

In the following paragraphs the emphasis has consequently been laid on studies using a variety of performance tests. There are many ways to classify such methods, e.g. by the specific mental function a task is thought to tap or simply by test duration. Similar to a classification used by Deutsch Lezak (1995) for neuropsychological tests, we will distinguish the following areas of mental performance ... 

There are no sharp borderlines between some of these areas of mental performance (elements of attention, perception and some motor function are involved in all forms of performance), and allocation to a specific area is debatable for man tests. When studies are planned in practice this will be considered by compiling a battery of tests containing some redundancy while still retaining parameters from various areas of performance. 

A CT scan or MRI of the brain following a strokelike episode reveals a lucency (an area of luminosity) that is consistent with infarction. Later, cerebral atrophy and calcifications may be observed on brain imaging studies. The vascular territories of focal brain lesions and the prior medical history of these patients differ substantially from those of typical patients with stroke. Serial MRI studies often demonstrate lesion resolution, differentiating these lesions from typical ischemic strokes. An electroencephalogram is often performed when seizures are a concern. This is especially necessary in MELAS since patients occasionally have intractable status epilepticus as a terminal condition. Mental deterioration usually progresses after repeated episodic attacks. Psychiatric abnormalities (e.g., altered mental status, schizophrenia) may accompany the strokelike episodes. The encephalopathy may progress to... 

Once it is determined that a person has one of the many types of mental or developmental disabilities, the most important point is to assure the person that he or she is now in a safe environment—to the extent such a declaration actually can be made. Any hospital or shelter will be full of sound and loud conversation, but if any more quiet areas exist, these people should be directed to them. Make sure the person has clearly understood instructions and don t hesitate to repeat. If you must perform a procedure on the individual, explain what you need to do and seek the person s permission. He or she may have established a safe boundary around him or herself that cannot be penetrated without his or her consent. 

In the simple example given above, automatization seems desirable. It makes you happier. If your mental activities unrelated to the job are used for, say, planning to improve other areas of your life, you are even being more efficient. You have more sensing and intellectual capacity than you need to perform the job efficiently, so you use only as much as you need and devote the rest to furthering your own ends. 

The beliefs and evaluations of a person s over health in general, rather than a particular mental or physical aspect, constitute their general health perceptions. Questions in this area reflect each person s own health preferences, values, needs, and attitudes, and thereby discriminate between individuals whose objective levels of physical and mental health, as defined by other measures, appear identical. Such self-perceptions are important for two reasons 1) reports of behavioral performance do not capture important subject manifestations of differences in... 

To assess the mental and psychomotor development of infants exposed to PCBs both pre- and postnatally, the Dutch standardized version of the Bayley Scales of Infant Development were administered at 3, 7, and 18 months of age. Both the MDI and the PDI were included in the assessments. The tests were performed at the infant s home in the presence of the parent(s) (Koopman-Esseboom et al. 1996). The evaluations of the infants using the Bayley Scales of Infant Development were undertaken only for the 207 children from Rotterdam. Rotterdam is an urban area thought to have higher exposures to PCBs than Groningen, a semi-urban area in northern Holland. 

I Mini-Mental State Examination (MMSE) screening instrument briefly tests several areas of cognition but not in depth. Score 0 (low performance) to 30 (high performance). 

Third, in the test-taking environment, it can be difficult to switch gears from regular math questions to quantitative comparisons completing the exercises in this book will make these mental gymnastics more comfortable as you grow familiar with the question format. Also, your performance on these questions will help you assess your overall math skill level. Because the quantitative comparison questions assess a wide variety of math topics, these exercises will help you pinpoint the areas of math for which you need further study.
