Summarizing scrambled stories

Subjects read stories 1,400 words long and wrote 60- to 80-word summaries of these stores. Reading time was either unrestricted or limited, and the stories were either presented in natural order or with their paragraphs scrambled. Reading times were longer for the scrambled stories, but the same kind of summaries were produced whether stories were presented in natural or scrambled order. When a well-structured story was used, judges were unable to distinguish the two types of summaries and rated the adequacy of summaries based upon the scrambled version about as high as that of summaries based upon normal stories. For a less well-structured story, judges could differentiate between the summaries from natural and scrambled stories. These results demonstrate the effectiveness of the story schema which permits subjects to comprehend scrambled stories by reorganizing them.     

Relevance of physical environment influences for toddler temperament

The present study investigated the relation of the physical environment to toddler and parent temperament. Measurement of the physical environment offers a unique way of disentangling environmental influences on temperament from child influences on the environment. Subjects were 82 12-month-old toddlers. The physical environment was assessed during six separate home observations, using codes from the Purdue Home Stimulation Inventory. Toddler temperament was measured by the Toddler Temperament Scale, and maternal temperament was assessed with the revised Dimensions of Temperament Scale. Results indicated that measures of crowding and availability of objects and visual stimuli were most consistently related to specific dimensions of toddler temperament. Relations between physical environment and maternal temperament were inconsistent. Partialling out maternal temperament did not substantially change observed relations between the physical environment and toddler temperament. Implications of these findings for our understanding of environmental contributions to the expression of temperament are discussed.     

Communicator Similarity,Fear Arousing Communications,and Compliance with Health Care Recommendations1

Using a pretest-treatment-multiple posttest design, two studies were conducted to investigate the effects of race of communicator and different levels of fear-arousing dental health appeals on reported anxiety, attitudes, information retention, and behavior change among 304 black, junior high school students. In addition to paper-and-pencil measures, a chemical dye (erythrosin), which stains red the bacteria concentrations on teeth, was used to measure changes of actual toothbrushing behavior. The results of the two studies for behavior change were reasonably consistent. Irrespective of the fear level of the message, the similar communicator produced more immediate behavior change than the dissimilar communicator, and correlations showed that anxiety reports were unrelated to behavior change. Overall, fear communications positively influenced anxiety and attitudes but did not affect behavior. The findings suggest that caution be exercised in using self reports as measures of effectiveness of persuasive communications and additional factors need to be incorporated into existing theories to account for differential reactions to threat appeals.     

Confirmatory factor analyses of DSM-IV Cluster C personality disorder criteria

Notwithstanding its research and clinical relevance, the dimensionality and validity of the DSM-IV avoidant, dependent, and obsessive-compulsive personality disorders (PDs) criteria is still a largely unexplored topic. The aim of this study was to test the factor structure for DSM-IV Cluster C PD criteria in a sample of 641 consecutively admitted outpatients. Factor analysis results suggested that avoidant, dependent, and obsessive-compulsive PDs share a common latent dimension, and supported the three-factor structure of both observer and self-report ratings of DSM-IV Cluster C PD criteria. The pattern of factor loadings, however, was different from the one expected according to the DSM-IV classification.     

Sex differences on a measure of conformity: comments on a recent study

Reysen and Reysen's recent article made a contribution to understanding of sex differences by interpreting the results through the lens of conformity research. Reinterpretation could refer to differences in perceptual sensitivity. The results, then, are theoretically and empirically consistent with the literature.     

Auditory--visual cross-modal perception of communicative stimuli in tufted capuchin monkeys (Cebus apella)

Research on cross-modal performance in nonhuman primates is limited to a small number of sensory modalities and testing methods. To broaden the scope of this research, the authors tested capuchin monkeys (Cebus apella) for a seldom-studied cross-modal capacity in nonhuman primates, auditory-visual recognition. Monkeys were simultaneously played 2 video recordings of a face producing different vocalizations and a sound recording of 1 of the vocalizations. Stimulus sets varied from naturally occurring conspecific vocalizations to experimentally controlled human speech stimuli. The authors found that monkeys preferred to view face recordings that matched presented vocal stimuli. Their preference did not differ significantly across stimulus species or other stimulus features. However, the reliability of the latter set of results may have been limited by sample size. From these results, the authors concluded that capuchin monkeys exhibit auditory-visual cross-modal perception of conspecific vocalizations.
