A follow-up developmental study of hypothesis behavior among mentally retarded and nonretarded children

To clarify the roles of IQ and mental age (MA) in hypothesis behavior, MA-matched subjects at three levels of IQ (70, 100, and 130) and three levels of MA ($\text{5}\text{1}\text{2}\text{, 7}\text{1}\text{2}\text{,}\text{and}\text{9}\text{1}\text{2}\text{years}$) received blank-trial discrimination learning problems using procedures designed to discourage position-oriented responding. With position responding discouraged, earlier findings were contradicted in that no hypothesis measure showed a main effect of IQ. This suggest that previously reported IQ group differences in hypothesis behavior may not reflect cognitive deficits inherently linked to low IQ, but instead may reflect the influence of specific methodological factors. The finding and interpretation are consistent with Zigler's (American Journal of Mental Deficiency, 1969, 73, 536–556) “developmental” theory of retardation and inconsistent with the general “difference” position. In additional findings, the predictions that subjects at all three MA levels would use hypotheses, and that retarded children from special-education classes would use hypotheses more often than retarded children “mainstreamed” in classes for the nonretarded were confirmed.

Parents’ Intelligence Mindsets Relate to Child Internalizing Problems: Moderation Through Child Gender

Parental belief systems can strongly influence children’s affect, behavior, and mental health. However, associations between specific kinds of parental beliefs and children’s mental health have not been thoroughly explored. One relevant belief system is parental intelligence mindset: beliefs about the malleability of intelligence. Children of parents who view intelligence as static (known as a fixed intelligence mindset), rather than malleable through effort (known as a growth intelligence mindset), experience more academic, self-regulatory, and motivational difficulty. However, associations between parental intelligence mindset and child mental health problems are unclear. Accordingly, we tested whether parents’ intelligence mindsets related to internalizing problems in their children (N?=?131, ages 5–8). Overall, parents with stronger fixed intelligence mindsets had children with greater internalizing problems, particularly social anxiety (characterized by fear of negative evaluation). Results further revealed that parents’ fixed intelligence mindsets were associated with overall internalizing problems and depressive symptoms in boys, but not girls. Results are the first to suggest and parse direct links between parents’ intelligence mindsets and youth internalizing problems.     

The lab versus the clinic. Effects of child and adolescent psychotherapy.

Four recent meta-analyses, involving more than 200 controlled outcome studies, have shown consistent evidence of beneficial therapy effects with children and adolescents. However, most of the studies involved experimental procedures, nonreferred subjects, specially trained therapists with small caseloads, and other features that may not represent conventional clinic therapy. Research focused on more representative treatment of referred clients in clinics has shown more modest effects; in fact, most clinic studies have not shown significant effects. Interpretation studies have not shown significant effects. Interpretation of these findings requires caution; such studies are few and most could profit from improved methodology. The clinic studies do raise questions as to whether the positive lab findings can be generalized to the clinics where most therapy occurs; however, the lab interventions that have worked so well may point the way to enhanced therapy effects in clinics.     

Relations among self-reported depressive symptoms in clinic-referred children versus adolescents.

Although there is consensus regarding the existence of childhood depression, disagreement remains as to whether symptoms are developmentally isomorphic. Previous studies focused on developmental differences in symptom levels; analyses of relations among symptoms may be more appropriate, however. Here both approaches were used to compare the Children's Depression Inventory responses from 1,030 clinic-referred children and adolescents. Four of nine symptom categories showed significant developmental differences in their correlations with total score. Externalizing behavior and guilt were more strongly related to depression in children than adolescents; affective symptoms and concerns about the future showed the reverse pattern. Results illustrate the importance of considering relations among symptoms as well as differences in symptom levels when evaluating theoretical claims about developmental differences in the nature of clinical syndromes.     

The Rorschach and structured tests of perception as indices of intellectual development in mentally retarded and nonretarded children

In a study of the developmental significance of certain perceptual activities, the Rorschach and four structured tests of perception were administered to five groups of children at various CA, MA, and IQ levels. All three Rorschach measures were significantly related to MA, as were all four of the structured tests. The Childrens' Embedded Figures Test was the best predictor of MA; it accounted for 52% of the variance, while the six remaining measures yielded nonsignificant increments to a multiple regression equation. In a factor analysis the four structured tests loaded on one factor (51% of total variance), while the three Rorschach variables loaded on a second (17%); MA loaded on both (.669 and .447, respectively). In an additional finding, Zigler's “developmental” hypothesis that level of development and not IQ determines cognitive competence, received partial support from 13 of 14 statistical tests.     

Colonic sensitivity in irritable bowel syndrome and normal subjects according to their hemispheric preference and cognitive style.

According to our earlier results, non-painful, weak afferent visceral signals may exert a steady influence on brain processes, including cognitive functions. In the present series colonic impulses of irritable bowel syndrome (IBS) subjects served as a model of chronic impact from the gut. Hemispheric preference, as well as cognitive style of information processing served as indicators of covert changes in brain functions. In twenty-one IBS patients and in ten control subjects of both sexes, the thresholds of minimal colonic distension sensitivity has been measured following the determination of hemispheric preference and of advantage in verbal or spatial information processing of the subjects. In IBS patients distension thresholds proved to be higher in verbals than in spatials, whereas in healthy controls the relationship of colonic thresholds and verbal versus spatial advantage was reversed. Among the normal controls with left hemisphere preference a significantly higher distension threshold has been observed than in those with right hemisphere preference, whereas in the IBS group such threshold-differences were not observable.
