CHARACTERISTICS OF SUCCESSFUL AND DROPOUT MDTA TRAINEES1

A study was designed to compare several variables of Manpower Development Training Act (MDTA) clients who dropped out of the program with those of clients who completed the program. A random sample of application cards was drawn for individuals enrolled in MDTA adult classes in Milwaukee, Wisconsin. Trainees who completed the program were more likely to be married, older, characterized by a more stable employment history prior to entering the program, and slightly more educated than were program dropouts. Clients who completed the program versus those who did not were not significantly different on the following variables: (1) sex; (2) counseling versus no counseling; (3) race; and (4) client reported physical disability.     

Stress-induced Fos-like Immunoreactivity in the Pons and the Medulla Oblongata of Rats

Immunoreactivity of the immediate early gene c-fos was used to investigate changes in the activity of brainstem neurons in response to acute stressors like immobilization, formalin-induced pain, cold exposure, hemorrhage and insulin-induced hypoglycemia. Different stressors induced Fos-like immunoreactivity in different pontine and medullary neurons. A single, 3 hour immobilization was found to be a very strong stimulus that activated brainstem catecholaminergic (tyrosine hydroxylase-immunopositive) neurons and cells in the raphe and certain pontine tegmental nuclei, as well as in the reticular formation. Pain, induced by a subcutaneous injection of formalin was also effective on catecholamine-synthesizing neurons and on others cells in the nucleus of the solitary tract. Cold exposure activated cells mainly in the sensory spinal trigeminal and parabrachial nuclei and in the so-called "pontine thermoregulatory area". Moderate Fos-like immunoreactivity was induced by a hypotonic (25%) hemorrhage in medullary catecholaminergic neurons, the nucleus of the solitary tract and the Barrington nucleus. Among stressful stimuli used, insulin-induced hypoglycemia elicited the smallest Fos activation in the lower brainstem. The present observations indicate that different stressors may use different neuronal pathways in the central organization of the stress response.     

Children's self-presentations with infants: Gender and ethnic comparisons

The assumption of differential socialization experiences lead to the hypothesis that African American children would be less stereotyped in their responses to infants than White American children. This study of fifty-three 8–10-year-old children from African American and White American working-to-middle class families supported the hypothesis. The children were photographed with a peer, an infant, and with an infant while acting as a parent. All children stood significantly closer to the infant in the role condition and exhibited more attraction behavior. As predicted, gender differences were evident between White girls and boys, but not between African American girls and boys. Findings suggested that social preferences for infants cannot be necessarily linked to gender. Discussion of the findings from earlier study with younger children (Reid et al., 1989) supported this conclusion.We gratefully acknowledge Carol S.

Pointing and the interference effect in obsessive‐compulsive disorder (OCD)

The interference effect in obsessive‐compulsive disorder (OCD) was investigated in order to analyze cognitive aspects of motor stereotypy in OCD‐related compulsions. So far, the domain of cognitive control in compulsive behavior has been under‐investigated. Twelve participants (OCD patients and healthy controls) completed a newly created computer‐based pointing task as well as standard clinical and psychological background measures. Findings showed that the patients displayed a larger visual interference effect compared to the controls and pointing paths were longer in time as well as distance when a distractor stimulus was present. It is concluded that, for compensation, patients would need to generate excessive amounts of attentional resources not available to overcome motor rigidity on the one side and visual distraction on the other side.     

Developmental origins of perfectionism among African American youth

The present study used a person-centered latent variable approach to classify types of perfectionism among 6th-grade African American children living in an urban setting. In particular, the authors were interested in determining whether an adaptive subtype could be found and validated against external criteria. The authors also attempted to identify any developmental precursors that could reliably differentiate the perfectionist subtypes. A social learning and competence framework was used to select potential 1st-grade risk and protective factors for future perfectionism profiles. Four classes best described the children's perfectionism scores in 6th grade. Three of these classes resembled the profiles most commonly seen in prior perfectionism research (Non-Critical/Adaptive, Critical/Maladaptive, and Non-Perfectionist). The fourth class, Non-Striving, was characterized by extremely low levels of reported personal standards. Sixth-grade correlates confirmed the distinctiveness of these classes. In particular, the Critical/Maladaptive and Non-Striving classes had higher rates of internalizing symptoms and disorders. Additionally, several 1st-grade predictors suggested unique developmental origins of these classes. The Critical/Maladaptive class was characterized by lower academic skills and elevated teacher-rated attention problems, hyperactivity, shyness, and peer rejection. The Non-Striving class had higher rates of family alcohol problems and lower levels of parent praise. Implications regarding the universal and culture-specific origins and effects of perfectionism are discussed.
