The connection between prenatal substance use and infant outcomes is a good example: although experimentation on humans is difficult medicine zalim lotion purchase 110 mg sinemet with amex, convergent evidence from a variety of animal and human studies supports quite strong conclusions about effects xerostomia medications side effects cheap 300mg sinemet mastercard. Intervention studies can provide an especially strong means for testing theories about the developmental significance of early experiences medications related to the blood trusted 110 mg sinemet. Government-subsidized early childhood intervention programs, nutritional supplements, home visitation programs, and parent training programs are but a few examples. Program evaluations enable policy makers to assess how program funds are being spent, whether and to what extent programs are being implemented as planned, and, ultimately, whether program par- of Sciences. Knowing that an intervention met its goals is a step in the right direction, but the real need is to move from this general conclusion to specific conclusions about which aspects of the intervention have which effects, to what degree, and under which circumstances (Rutter et al. Selection bias occurs when characteristics that predict program participation are also associated with outcomes. Simultaneity bias can also occur, especially when program activities and outcomes are studied over time. There is, however, an important distinction between the kinds of causal questions that arise in basic research and those that arise in program evaluations. Basic developmental science typically assesses causal connections between events that unfold naturally over time. In contrast, program evaluations assess the effects of deliberately planned interventions-activities that would not occur in the absence of a new policy. For this reason, it is often more plausible, both ethically and logistically, to conduct experiments in program evaluation than in basic developmental science. Such experimentation not only provides strong causal inferences about the impact of the program, but it can also provide new insights of great relevance to basic research. Experimental evaluations have also shown that some promising ideas do not appear to translate into better childhood outcomes, a result that requires a deeper reflection on the validity of the theory behind the program, as well as on program implementation. This interplay between basic and applied research is essential to the vitality of the field. This discussion may seem to imply that all program evaluations should be randomized experiments. Although we strongly suspect that randomized experiments are underutilized in program evaluation research, they are not the right tool for addressing all questions about interventions and special conditions must hold before a randomized experiment is feasible or desirable. Randomized experiments are of use when a clearly stated causal question is on the table. A test of the impact of the program generally makes sense only when the program is based on sound theory regarding modifiable mechanisms that are associated with the outcomes of interest. A premature and expensive test of impact can be a waste of money and can demoralize those who are trying to invent promising new programs. The results from such an evaluation are difficult to interpret, creating confusion rather than clarification about policy and theory. A randomized experiment often becomes an attractive option, yet the decision about how to design a causal-comparative study must be made on a case-by-case basis. For example, when funds become available for a promising new intervention, there will often be considerable interest among parents in participating but insufficient resources to accommodate all interested families. In this setting, a lottery can be used to select who will participate-in effect, a randomized selection. If the results of the randomized experiment are promising, resources may then become available to accommodate more families. However, in other cases, randomized experiments may not be feasible or desirable for logistical or political reasons. In still other cases, it may already be known from previous experimentation that a program works under the special conditions of the experiment. The question then may be whether the program produces significant effects in a routine (nonexperimental) setting. Nonexperimental methods are then required to cope with selection and simultaneity biases. It is also important to recognize that an initially randomized experiment can deteriorate under the impact of noncompliance, becoming a nonrandomized experiment, also called a "quasi-experiment. The same processes are not at work with the comparable set of control families not receiving the program.
This developmental pattern again suggests that certain components of language may be resilient-here in the face of variations in the timing of acquisition-while other components may be relatively fragile symptoms joint pain and tiredness discount sinemet 125mg with visa. The ability to medicine runny nose buy sinemet amex learn the fragile components of language does not drop off precipitously medicine 4 times a day buy cheap sinemet 300mg online. Rather, there appears to be a decline after age 6 or 7-a decline that begins to plateau and become less steep in late adolescence. Importantly, unlike early learners who tend to follow the same developmental trajectory (that is, there is strikingly little variability across them), late learners vary quite a bit. Some achieve native-like competence even on the fragile properties of language, while others do not. This research is providing a much more refined understanding of the ways in which early language experience provides a foundation for later language facility. For example, Neville and her colleagues have found, in normal, right-handed, monolingual adults, that nouns and verbs (words that provide semantic information-that is, about meaning) elicit a markedly different pattern of brain activity than do prepositions and conjunctions (functional words that provide grammatical information). These findings suggest that different neural systems mediate the processing of semantic and grammatical information in adults (in particular, a greater role for more posterior temporal-parietal systems in semantic processing and for anterior temporal systems within the left hemisphere in grammatical processing). Impressively, these findings are robust across languages, including sign languages (although there appears to be more right-hemisphere involvement in processing a sign language like American Sign Language than in processing a spoken language like English). The work of Neville and her colleagues also bears on issues of the timing of environmental inputs. In studies of cerebral organization in individuals who learned English at different times in the life span, Neville and colleagues have found that aspects of semantic and grammatical processing differ markedly in the degree to which they depend on the timing of lan- of Sciences. In particular, in a group of ChineseEnglish bilinguals, delays as long as 16 years in exposure to English had very little effect on the organization of the brain systems important in lexical semantics. That is, the brain system underlying the organization of nouns and verbs was disrupted very little. However, delays of only 4 years had significant effects on aspects of brain organization linked to grammatical processing. Brain organization underlying function words, such as prepositions and conjunctions, was severely disrupted. Similar patterns have been found in studies of congenitally deaf individuals who learned English late and as a second language (American Sign Language was their first language). These findings suggest that the systems that mediate the processing of at least some types of grammatical information are much more modifiable by-and therefore vulnerable to-variations in language experience. This is demonstrated again below, in the discussion of interventions with children with specific language disorder. In general, it seems important that practitioners consider the data generated from studies of the effects-and noneffects-of exceptional circumstances on language learning, for they provide important information on the boundary conditions of language learning. Moreover, these phenomena are the anchor points for theories of language development that take into account the resilience of language learning within more normal ranges of both environmental and organic variation. The Impact of Linguistic Input on Language Learning and Language Production As noted earlier, conventional language input is not essential for a young child to develop a language-like system and use it to communicate with others. However, a language model may play a central role in determining how often and when those linguistic properties are used. We noted above, for example, the infrequent use of language to express emotions among children who had been institutionalized. Another example concerns the ability to communicate about objects and events in other than the here and now. Deaf children who are not exposed to usable linguistic input (because their parents do not know American Sign Language, for example) not only use gesture to convey information about the here and now, but they also use it to converse about past, future, and hypothetical events (Morford and Goldin-Meadow, 1997). Linguistic input is thus not essential for a child to communicate about the nonpresent. And the amount and type of talk children hear, in turn, can influence how well they remember events in the past (Reese et al. For example, during the period from 11 to 18 months, children in one study heard, on average, 325 utterances addressed to them per hour (Hart and Risley, 1995). But the range was enormous-one child heard as many as 793 utterances per hours, another as few as 56. The amount of speech children heard from their parents at 18 months was strongly correlated with the amount of speech they heard at age 3. Moreover, these differences tended to be associated with socioeconomic status, although it is important to recognize that the sample of 42 participating families was small and not representative and so cannot provide firm evidence regarding social class differences. Often researchers videotape mothers and their young children to explore parental verbal input and child output.
Heavy drinking and the consequent incidence of fetal alcohol syndrome are much higher among black Americans than among white Americans (Abel treatment brown recluse spider bite buy sinemet once a day, 1995; Faden et al medicine jokes buy sinemet 110 mg fast delivery. Defined by a specific pattern of facial and other physical deformities accompanied by growth retardation treatment ibs generic sinemet 125mg without a prescription, fetal alcohol syndrome identifies a relatively small proportion of children prenatally affected by alcohol. The Institute of Medicine (1996) recently suggested that the term "alcoholrelated neurodevelopmental disorder" be used to focus specifically on brain dysfunctions in the presence of significant prenatal alcohol exposure but without physical deformities. Fetal alcohol syndrome is estimated to occur at a rate of 1-3 per 1,000 live births; alcohol-related neurodevelopmental disorder is estimated to be at least 10 times more prevalent. Brain dysfunctions in alcohol-exposed children without fetal alcohol syndrome are often as severe as those in children with the full impairment. A variety of neurobehavioral changes have been observed in children exposed to alcohol prenatally. These effects range from problems with attention and memory to poor motor coordination to difficulty with problem solving and abstract thinking. Infants and toddlers may be delayed in reaching important milestones, may have difficulty tuning out excess sensory stimuli, and often are hyperactive. Both severely and more mildly affected children demonstrate slower information processing and longer reaction times and appear to have specific problems with arithmetic (Jacobson et al. These effects have been documented through the early adolescent years and into adulthood. In addition, more specific and sensitive measures may indicate differing effects of various developmental neurotoxins (Jacobson, 1998). The importance of considering timing (when a condition occurs during development), severity (degree or dose), and chronicity (how long it lasts) in attempting to understand the effects of early biological insults is well illustrated by prenatal alcohol exposure. In general, the prenatal period appears to be distinguished by its sensitivity to a large array of harmful conditions. For instance, alcohol exposure early in gestation has different effects on the developing brain from similar exposure later on. However, animal models-with experimental manipulation of alcohol exposure and direct examination of brain tissue-continue to provide crucial information. In the mouse, for example, exposure to alcohol on days 7 and 8 of gestation results in not only the typical facial deformities of fetal alcohol syndrome but also brain anomalies, such as small overall size and deficiencies in cerebral hemispheres, striatum, olfactory bulbs, limbic structures, the corpus callosum, and lateral ventricles. Research with humans also shows that the timing of prenatal alcohol exposure has differential effects (Connor and Streissguth, 1996; Institute of Medicine, 1996; Jacobson et al. Fetal exposure to alcohol during the second and especially the third trimester of pregnancy appears to be a time of particular vulnerability for the impaired neurobehavioral development, although some data suggest that these effects extend throughout pregnancy. Dividing cells appear to be particularly sensitive to the toxic effects of alcohol, and hence a period during which extensive neurogenesis occurs would be a time of acute sensitivity to the effects of alcohol. The cognitive effects associated with exposure to alcohol later in pregnancy, for example, may be associated with the high level of neuronal cell division in pertinent parts of the brain that occurs during the third trimester. The severity of exposure is another important factor in understanding ill effects, perhaps as important as the timing. In addition, episodic binge drinking appears to be more harmful to the developing brain than equivalent levels of alcohol consumed steadily. Experimental animal studies indicate that ingestion of a given dose of alcohol over a short period of time generates a greater peak blood alcohol concentration than the same dose ingested over several days (Bonthius and West, 1990). Thus, the developing fetus is actually exposed to a higher level of alcohol in binge drinking and has been found in animal research to experience greater neuronal (Bonthius and West, 1990) and behavioral (Goodlett et al. In humans, binge drinking is more of a problem than is usually recognized, because moderate drinkers, who consume 1-2 drinks of Sciences. When juxtaposed with evidence on the timing of alcohol exposure, the detrimental effects of binge drinking suggest that any bouts of drinking during pregnancy run the risk of damaging some aspect of the developing brain. Chronicity is another important factor in understanding the effects of early biological insults. In the case of prenatal alcohol exposure, it appears that the effects on the fetus worsen with successive pregnancies. Specifically, older mothers who are moderate-to-heavy drinkers are at higher risk for having an affected offspring (Institute of Medicine, 1996). This may be due to reduced ability to metabolize alcohol by women who have been drinking heavily for several years (Jacobson et al. In the case of alcohol exposure, chronicity should thus be thought of as a dimension of risk both within and between pregnancies. Research on early biological insults has also yielded information on modifiability or brain plasticity.
