Findings are presented from an Icelandic randomized control trial (RCT) evaluating parent management training – Oregon model (PMTO?), a parent training intervention designed to improve parenting practices and reduce child behavior problems. In a prior report from this effectiveness study that focused on child outcomes, children in the PMTO condition showed greater reductions in reported child adjustment problems relative to the comparison group. The present report focuses on observed parenting practices as the targeted outcome, with risk by treatment moderators also tested. It was hypothesized that mothers assigned to the PMTO condition would show greater gains in pre‐post parenting practices relative to controls. The sample was recruited from five municipalities throughout Iceland and included 102 participating families of children with behavior problems. Cases were referred by community professionals and randomly assigned to either PMTO (n = 51) or community services usually offered (n = 51). Child age ranged from 5 to 12 years; 73% were boys. Contrary to expectations, findings showed no main effects for changes in maternal parenting. However, evaluation of risk by treatment moderators showed greater gains in parenting practices for mothers who increased in depressed mood within the PMTO group relative to their counterparts in the comparison group. This finding suggests that PMTO prevented the expected damaging effects of depression on maternal parenting. Failure to find hypothesized main effects may indicate that there were some unobserved factors regarding the measurement and a need to further adapt the global observational procedures to Icelandic culture. 相似文献

A selective prevention design was applied to 238 recently separated families. Of these, 153 mothers randomly assigned to the experimental (E) group participated in 14 group sessions focused on Parent Management Treatment (PMT). Prior analyses showed that, over time, the group of families in the untreated group deteriorated in both parenting practices and in child outcomes. In keeping with the classic prevention pattern, families in the E group showed modest improvements in parenting and in child outcomes. Improvements in parenting were associated with significant reductions in problem behavior. The data showed that those mothers who improved their parenting skills during the first 12 months also showed significant reductions in maternal depression during that same interval. A cross-lagged panel analysis showed that a reduction in maternal depression during the first year of the study was a significant predictor of maintenance or improvements over the next 18 months. The findings are consistent with the concept of the family as a system. 相似文献

In a recent paper, Clahsen and Almazan (1998) reported a dissociation between unimpaired regular and impaired irregular past tense morphology in English Williams syndrome (WS). Our aim is to investigate whether these findings carry over to another language with different morphological systems. We present data on regular and irregular participles and noun plurals from 2 German WS subjects and 10 controls matching in mental age. For noun plurals, regular morphology is intact in WS, whereas irregular forms are impaired. A similar dissociation is observed for participles: while regular inflection is unimpaired, WS subjects, unlike controls, apply the regular suffix incorrectly to frequent irregular verbs. We discuss our findings against the current debate between connectionist and dualistic approaches to the language faculty. 相似文献

Rats have been shown to avoid consuming a flavor, but prefer a location, previously paired with amphetamine or morphine. A series of 4 experiments evaluated the hedonic properties of amphetamine and morphine in the house musk shrew (Suncus murinus), an insectivore that (unlike rats) is capable of vomiting when exposed to toxins. Unlike rats, amphetamine (20 mg/kg) and morphine (20 mg/kg) produced both a conditioned sucrose (0.3 M) and saccharin (0.1%) preference in shrews (administered intraperitoneally), when measured by both a 1- and a 2-bottle test. At the same dose, both drugs also produced a place preference in shrews. These results suggest that the potential of rewarding drugs to produce taste avoidance may vary on the basis of the ability of the species to vomit. 相似文献

In a mental rotation task, children 5 and 6 years of age and adults had to decide as quickly as possible if a photograph of a hand showed a left or a right limb. The visually presented hands were left and right hands in palm or in back view, presented in four different angles of rotation. Participants had to give their responses with their own hands either in a regular, palms-down posture or in an inverted, palms-up posture. For both children and adults, variation of the posture of their own hand had a significant effect. Reaction times were longer the more awkward it was to bring their own hand into the position shown in the stimulus photograph. These results, together with other converging evidence, strongly suggest that young children's kinetic imagery is guided by motor processes, even more so than adults'. 相似文献

To understand how children manage anger and engage in various forms of aggression, it is important to observe children responding to peer provocation. Observing children's anger and aggression poses serious ethical and practical challenges, especially with samples of older children and adolescents. This article describes 2 laboratory methods for observing children's responses to peer provocation: 1 involves participants playing a game with a provoking child actor, and the other involves a pair of close friends responding to an actor posing as a difficult play partner. Both methods are described in detail, ethical safeguards are discussed, and evidence is presented to show that children understand their research rights in these types of investigations. 相似文献
