Solving problems by analogy: The benefits and detriments of hints and depressed moods

In Experiment 1, mildly depressed (dysphoric) and nondysphoric subjects tried to solve logic problems that were analogous to subsequent target problems; then they attempted target solutions with or without hints in the form of the anologues’ themes. Target solutions were impaired by the hints in the nondysphoric group alone. Experiment 2A was a no-training control to verify that transfer did indeed occur. In Experiment 2B, all subjects received hints in the transfer phase; the training phase was either problem oriented (as in Experiment 1) or memory oriented. Again, nondysphoric subjects solved fewer problems following problem-oriented training than did both dysphoric subjects in that condition and nondysphoric subjects with memory-oriented training. Experiment 3 replicated the previous results in the nondysphoric samples. We interpret these findings within the transferappropriate processing framework.     

Detoxification at Home: A Brief Solution-Oriented Family Systems Approach

The authors propose an outpatient, solution-oriented, family systems approach to detoxification from alcohol and/or drugs. Research indicates that outpatient detoxification is a viable option, one that will likely be utilized even more frequently as health care costs continue to rise. Nontraditional assumptions about the process of detoxification are suggested that challenge traditional notions about detoxification being only a biomedical, pretreatment event. Criteria are provided for determining the appropriateness of clients for outpatient detoxification and offer information about typical withdrawal symptoms and guidelines for the detoxification environment at home. A case example illustrates the application of this approach in a community mental health program. Suggestions for adapting this approach to various settings are also offered.     

Application of four procedures for detecting differential item functioning in polytomous items

The authors describe and use four methods for detecting Differential Item Functioning in polytomous items: Mantel, Generalized Mantel-Haenszel (GMH), Ordinal Logistic Regression (RLO), and Discriminant Logistic Regression (RLD). For each procedure, the theoretical model and the measure of effect size are described. The data from the "Reading Comprehension Test" from the PISA2000 evaluation program were analyzed using a cross-validation design. Two booklets were independently evaluated in the American and Spanish samples. Adopting as decision rule the significance of the statistical test and the measurement of the effect size, agreement among the evaluated procedures was total for two of the analyzed items.     

Discourse after Closed Head Injury in Young Children

This study examined narrative discourse in 23 children, ages 6 to 8 years, who sustained a severe closed head injury (CHI) at least 1 year prior to assessment. Narratives were analyzed at multiple levels using language and information structure measures. Results revealed significant discourse impairments in the CHI group on all measures of information structure, whereas differences in the linguistic domain failed to reach significance. In addition, effects of age at injury and lateralization of lesion on discourse were considered. Although no significant differences were found according to age at injury, a consistent pattern of generally poorer discourse scores was found for the early injured group (<5 years). With regard to lesion focus, the group findings were unimpressive. However, preliminary examination of individual CHI cases with relatively large lateralized lesions suggested that the late injured children may show the language–brain patterns reported in brain-injured adults, whereas early injured children may not.
