The Prevalence of Serious Emotional Disturbance: A Re-Analysis of Community Studies

The goal of these analyses was to use existing data to provide an empirically-based estimate of the prevalence in the population of Serious Emotional Disturbance (SED) in children and adolescents, to assist States in their task, required under PL 102-321, of including such estimates in their applications for Block Grant funds. Seven data sets were identified that could provide estimates of SED. The principal investigators agreed on common definitions of the key components of SED: a psychiatric diagnosis and significant functional impairment. Two definitions of impairment were used: domain-specific (impairment in one or more of three areas of functioning) and global (in the worst 10% over all). They also defined a set of correlates and risk factors for SED: age, gender, race/ethnicity, and poverty. Investigators then reanalyzed their own data, using these standard definitions, and calculated the proportion of SED youth who received mental health care. The median estimate of SED with global impairment was 5.4%, with a range from 4.3% to 7.4%. Estimates of SED with domain-specific impairment ranged from 5.5% to 16.9% (median 7.7%). Rates were slightly higher in boys. There were no clear ethnic differences. Poverty doubled the risk of SED. Only one SED child in four had recently received mental health care. Estimates of SED are critically dependent on the method used to define diagnosis and functional impairment. Using common definitions, seven studies produced fairly consistent estimates, which were similar to the estimate of prevalence of Serious Mental Illness (SMI) in adults. Implications for the estimate of State-by-State prevalence rates are discussed.     

Dispositions and Antidotes

C.B. Martin has shown that the simple conditional analysis of disposition concepts (x is disposed at time t to give response r to stimulus s) is in error. This is due to finkish dispositions which are caused to disappear by the stimulus s. David Lewis has proposed an improved analysis which takes account of finkish dispositions by requiring that the appropriate causal basis remains for a sufficiently long time. I argue that Lewis' analysis also fails, because of the existence of antidotes. An antidote to a disposition interferes with its normal operation so that the stimulus does not bring about the usual response. I consider several possible defences of Lewis' analysis and a plausible repair, but find these unsatisfactory. I conclude by suggesting that an analysis of disposition concepts is not available because an unavoidable indexical element (e.g., reference to normal circumstances) is present in explanations of these concepts. In this regard they may be thought of as akin to theoretical or natural kind concepts.     

Age at menarche and digit ratio (2D:4D): relationships with body dissatisfaction, drive for thinness, and bulimia symptoms in women

This study examined the hypothesis that lower prenatal androgen exposure and earlier puberty are associated with more dysfunctional eating attitudes and behaviors. Relationships between both age at menarche (AAM) and 2D:4D (a marker of prenatal androgen exposure), and EDI-2-Body Dissatisfaction, EDI-2-Drive for Thinness, and EDI-2-Bulimia scores, were examined in women using correlations and regressions. Earlier menarche was associated with higher drive for thinness after controlling for BMI and negative affect, but only in women who were not exclusively heterosexual. Higher 2D:4D was associated with higher Bulimia and Body Dissatisfaction scores, but only in exclusively heterosexual women, and relationships disappeared when covariates were controlled. Later AAM and higher 2D:4D were unique predictors of higher Bulimia scores for exclusive heterosexuals when BMI was controlled. These findings suggest future research should examine sexual orientation as a mediator or moderator of prenatal and postnatal organizational hormonal effects on women's disordered eating attitudes and behaviors.     

Can people strategically control the encoding and retrieval of some morphologic and typographic details of words?

This study investigated whether the encoding and retrieval of plurality information and letter-case information of words in recognition memory can be inhibited. Response-deadline experiments (Hintzman & Curran, 1994) using single words have indicted a controlled processing mode, whereas studies using meaningful sentences (e.g., Jou & Harris, 1991) have indicated an automatic mode of processing plurality information. Two similar opposing views have existed on the processing of letter-case information. The abstractionist view contends that we retain the abstract lexical information and discard the superficial perceptual case information. The proceduralist view holds that perceptual details cannot be separated from the lexical information. Using an intentional and an attention-diverted learning procedure and instructions to ignore plurality and case, we found that subjects experienced a consistent interference effect of changed plurality from study to test but slightly less interference from changed case, suggesting strong automaticity for plurality, and comparatively less automaticity, for case processing.     

“Test-Tube Baby” procedures: Stress and judgements under uncertainty

Patients participating in an in vim fertilisation with embryo transfer (IVF and ET) programme face uncertainty at each stage of the procedure. Research on heuristics and on stress lead to predictions about behaviour in situations of uncertainty. It was predicted that IVF and ET participants would overestimate the likelihood of success, due to publicity the process has received, and would underestimate the likelihood of an earlier, less publicised. stage in the procedure. Both predictions were confirmed in a total of 70 participants (26 women at out-patient clines, 23 of their partners and 21 surgical in-patients). All the men and all but one woman overestimated the likelihood of becoming pregnant and having a baby. and most of the surgical patients underestimated the likelihood of egg recovery. Estimates were not related to patients' confidence about their information, confirming previous evidence about confidence in inaccurate judgements based on heuristics. Data on patients' distress as indicated by mood rating show high anxiety at points of uncertainty and Pailure, as found in other studies of stress. While the couples shared their inaccurate judgements. they did not necessarily share their distress. The results are discussed in terms of patients' decision making. coping strategies and the implications for doctor-patient communication.     

Social attitudes modulate automatic imitation

In naturalistic interpersonal settings, mimicry or “automatic imitation” generates liking, affiliation, cooperation and other positive social attitudes. The purpose of this study was to find out whether the relationship between social attitudes and mimicry is bidirectional: Do social attitudes have a direct and specific effect on mimicry? Participants were primed with pro-social, neutral or anti-social words in a scrambled sentence task. They were then tested for mimicry using a stimulus-response compatibility procedure. In this procedure, participants were required to perform a pre-specified movement (e.g. opening their hand) on presentation of a compatible (open) or incompatible (close) hand movement. Reaction time data were collected using electromyography (EMG) and the magnitude of the mimicry/automatic imitation effect was calculated by subtracting reaction times on compatible trials from those on incompatible trials. Pro-social priming produced a larger automatic imitation effect than anti-social priming, indicating that the relationship between mimicry and social attitudes is bidirectional, and that social attitudes have a direct and specific effect on the tendency to imitate behavior without intention or conscious awareness.     

Responsible Research: What is Expected?

"Responsible research" and "good science" are concepts with various meanings depending on one's perspective and assumptions. Fellow researchers, research participants, policy makers and the general public also have differing expectations of the benefits of research ranging from accurate and reliable data that extend the body of knowledge, to solutions to societal concerns. Unless these differing constituencies articulate their differing views they may fail to communicate and undermine the value of research to society.
