Factors affecting utilization of evaluation findings by direct service staff

Simulated evaluation report abstracts were used to determine whether factors previously identified as enhancing utilization of evaluation findings by policy level decisionmakers and agency directors also enhance utilization by direct service staff. Respondents were 238 direct service staff members in mental health agencies. Dependent variables were perceived usefulness and perceived truthfulness. The predictor variables were relevance of the evaluation, staff participation, quality of research design and specificity of recommendations. All predictor variables except the last were significant but relevance explained almost all the variance. The two dependent variables were highly correlated and virtually could not be distinguished from each other. Rosemary Holland is currently working as a private consultant to mental health agencies for program development and program evaluation. She has extensive experience in the administration and planning of mental health services. Dr. Holland's primary interest is in user-initiated evaluations. She is on leave this year from the social work department of the University of Detroit.     

Use of semantic context by patients with Alzheimer's disease

In this study we used semantic-priming procedures to examine limitations in the use of semantic context by patients with Alzheimer's disease. We also tried to determine whether any such contextual effects were mediated solely through automatic processes or whether attentional processes were also involved. Three tasks were applied to examine the effect of semantic context on the performance of 18 normal elderly and 18 normal young subjects, and on 18 patients with Alzheimer's disease. When normal and demented subjects were asked to decide whether a given item was a member of a certain category, results showed that their response times were equally affected by the item's dominance in the category. The time that demented patients took to recognize a word was actually affected more by the semantic context provided by a priming sentence than was that of normal subjects. When asked to generate the final word of an incomplete sentence, demented subjects performed very poorly unless potential responses were highly constrained by sentence context.     

Control by stimulus features during fading.

Sixteen children were given four successive circle-size discrimination problems with luminance as the fading stimulus. Children who were first presented with a difficult size discrimination failed to acquire this discrimination. Those who first received an easy discrimination learned the difficult discrimination. At the end of each 10-trial block, two probe stimuli were presented to monitor any shift in control from luminance to size. One probe was the same size as the positive stimulus but of different luminance; the other was the same luminance but of different size. If, in the course of fading, size and luminance both controlled responding, fading was successful. If luminance alone controlled responding until the end of fading, the size discrimination was not established. Dual control, and thus successful fading, resulted when the target stimuli were very discriminable, or when the target stimuli were subtly different provided that previous fading series had first established less subtle discriminations.     

Canonical versus factor analytic perspectives on the structure of associations between the MMPI and the Buss-Durkee Hostility Inventory

A canonical correlational analysis of MMPI profiles versus Buss-Durkee hostility and aggression scales was conducted, resulting in the identification of a general hostility-aggression-maladjustment dimension and three relatively specific aggression-personality relationships. These findings were contrasted with those obtained from a factor analysis of the combination of both sets of scores. Though often used in previous studies of associations between the Buss-Durkee Hostility Inventory and other measures, factor analysis was seen to be less than optimally suited to such a purpose. It was concluded that canonical correlation is preferable to factor analysis when seeking to clarify the multivariate structure of relationships between two sets of variables.     

A clarification of continuous repertoire development

The key-peck response of five pigeons was reinforced on a schedule whenever the interval between pecks at two response keys was between 1.0 and 2.33 seconds in the presence of a 2,500-Hertz tone or between 4.66 and 6.0 seconds in the presence of a 1250-Hertz tone. There was no tendency for responses of intermediate duration to occur when test tones of intermediate frequency were presented. This result clarifies a previous finding using a similar procedure but with a visual intensity stimulus dimension.     

Forgiveness and its associations with prosocial thinking, feeling, and doing beyond the relationship with the offender

Past research has revealed that forgiveness promotes prosocial cognition, feeling, and behavior toward the offender. The present research extends this research by examining whether forgiveness may spill over beyond the relationship with the offender, promoting generalized prosocial orientation. Consistent with hypotheses, three studies revealed that forgiveness compared to unforgiveness is generally associated with higher levels of a generalized prosocial orientation, as indicated by higher levels of a we frame of mind (as indicated by a greater use of first-person plural pronouns, e.g., we, us, in a language task) and greater feelings of relatedness toward others in general. Moreover, forgiveness (vs. unforgiveness) was even associated with greater probability of donating to charity and greater willingness to engage in volunteering. Finally, the authors found that unforgiveness reduces tendencies toward generalized prosocial orientation, whereas forgiveness restores generalized prosocial orientation to baseline levels within the relationship.     

Validation of the Clance Imposter Phenomenon Scale

The Clance Impostor Phenomenon Scale (CIPS; Clance, 1985) was compared to the newly developed Perceived Fraudulence Scale (Kolligian & Sternberg, 1991). The two scales were found to have high internal consistency and to correlate in a similar manner with other measures. Further, discriminant validity evidence for the Impostor Phenomenon (IP) was provided by comparing the CIPS to measures of depression, self-esteem, social anxiety, and self-monitoring. The IP was related to, but substantially discriminable from, these constructs. Finally, construct validity evidence for the CIPS was provided through principal components analysis that yielded three stable factors: Fake, Discount, and Luck.     

A remark on Bower's estimate for the one-element Markov learning model

For the case of the one-element Markov learning model for which the guessing parameterp is assumed known the efficiency of Bower's method of moments estimatorc ⁺ for the learning parameter,c, is found. It seems that althoughc ⁺ is not eficient, for some practical value ofc it is not very inefficient. Ifp andc are small,, the maximum likelihood estimate, andc ⁺ have approximately the same first term when expanded in powers ofp.This work was facilitated by a grant from the National Science Foundation (GS-341)
