Increased hedonic differences despite increases in hedonic range

Viewing hedonically negative paintings increased the hedonic ratings of subsequently viewed test paintings (positive hedonic contrast; Experiment 1) and also increased the degree of preference between the test paintings (Experiments 2 and 3). This result differs from the reduction in hedonic preference (hedonic condensation) that accompanies negative hedonic contrast. It also differs from the reduction in perceived differences that usually accompanies expansion of stimulus range and that is predicted by numerous theories.     

Having Our Say: African American Women,Diversity, and Counseling

African American female counseling professionals contribute greatly to the multicultural growth of the counseling profession by spurring the profession's evolution and defining new paradigms and counseling activities. Despite their contributions, they face serious organizational, intrapersonal, and interpersonal challenges to their success in academia. This article seeks to elucidate the challenges to African American female counseling professionals and offers systemic and personal strategies that will facilitate the profession's evolution to culturally competent, ethical, and intentional helping orientations and worldviews.     

Psychometric Properties of Parent–Child (0–5 years) Interaction Outcome Measures as Used in Randomized Controlled Trials of Parent Programs: A Systematic Review

This systematic review sought to identify observational measures of parent–child interactions commonly implemented in parenting program research, and to assess the level of psychometric evidence available for their use with this age group. Two separate searches of the same databases were conducted; firstly, to identify eligible instruments, and secondly to identify studies reporting on the psychometric properties of the identified measures. Five commercial platforms hosting 19 electronic databases were searched from their inception to conducted search dates. Fourteen measures were identified from Search 1; a systematic search of randomized controlled trial evaluations of parenting programs. For Search 2, inclusion/exclusion criteria were applied to 1327 retrieved papers that described the development and/or validation of the 14 measures identified in Search 1. Seventeen articles met the inclusion criteria, resulting in five observational measures for the final review. Data were extracted and synthesized using the COSMIN rating system to describe the methodological quality of each article alongside the overall quality rating of the psychometric property reported for each measure using the Terwee checklist. Measure reliability was categorized into four domains (internal consistency, test-re-test, inter-rater, and intra-rater). Measure validity was categorized into four domains (content, structural, convergent/divergent, and discriminant). Results indicated that the majority of psychometric evidence related to children aged from birth the three with internal consistency, inter-rater reliability, and structural validity the most commonly reported properties, although this evidence was often weak. The findings suggest further validation of the included measures is required to establish acceptability for the whole target age group.

     

Effects of Performance Context on Processing Speed and Performance Ratings

The present study demonstrated that the presence of evaluatively polarized context performances not only produces contrast and halo effects on judgments of a target performance, but also causes judgments to be made much faster. Processing speed and positive halo were highly correlated, supporting the notion that halo in performance ratings results from raters' recall and use of a single, general impression. Furthermore, regression analyses demonstrated that processing speed mediates the relationship between context and halo. The relationship between these findings, halo, processing speed, and general impressions, as well as implications for performance appraisals, are discussed.     

From sharing to dividing: young children’s understanding of division

Children have particular difficulty with division problems, as compared to sharing problems. An inability to discriminate between the dividend, divisor and quotient might contribute to their difficulty with division. This study investigates whether young children (5–9 years) were able to discriminate between the divisor and quotient in simple division problems that were modeled for them. Children were presented with partitive and quotitive division problems in which the dividend was grouped either by the divisor or by the quotient. The children showed a very different pattern of results in the partitive and quotitive problems; they found it easier to identify the answer (quotient) when the dividend was grouped by the divisor in partitive problems and by the quotient in quotitive problems. It is argued that children rely on a schema of action of creating ‘portions’ when they first learn about division, and that the ‘portions’ produced by sharing are different in partitive and quotitive problems. We discuss this finding in terms of the importance of problem representation, children’s schemas of action and mental models.     

Reliability and Validity of the Complex Postformal Thought Questionnaire: Assessing Adults’ Cognitive Development

Three studies investigated the psychometric properties of the complex postformal thought (PFT) questionnaire (Sinnott, unpublished scale, 1998; Sinnott and Johnson 1997), which is a measure of adult cognitive development. The scale was found to be moderately reliable (α = .63). To assess construct validity, a comparison of participants’ performance on the PFT scale to their performance on the Need for Cognition scale was conducted, which indicated the PFT scale is valid measure of complex thought. Factor analysis reduced the scale to three factors, which correspond to important components of PFT: Multiple Elements, Subjective Choice, and Underlying Complexities. Implications for understanding the nature of adult cognitive development and the usefulness of this new measure for research in this area are discussed.     

Stereoscopic shape discrimination is well preserved across changes in object size

A single experiment evaluated human observers’ ability to discriminate the shape of solid objects that varied in size and orientation in depth. The object shapes were defined by binocular disparity, Lambertian shading, and texture. The object surfaces were smoothly curved and had naturalistic shapes, resembling those of water-smoothed granite rocks. On any given trial, two objects were presented that were either the same or different in terms of shape. When the “same” objects were presented, they differed in their orientation in depth by 25°, 45°, or 65°. The observers were required to judge whether any given pair of objects was the “same” or “different” in terms of shape. The size of the objects was also varied by amounts up to ±40% relative to the standard size. The observers’ shape discrimination performance was strongly affected by the magnitude of the orientation changes in depth - thus, their performance was viewpoint dependent. In contrast, the observers’ shape discrimination abilities were only slightly affected by changes in the overall size of the objects. It appears that human observers can recognize the three-dimensional shape of objects in a manner that is relatively independent of size.     

VERB™ Summer Scorecard: Findings from a Multi-level Community-based Physical Activity Intervention for Tweens

The benefits of physical activity for adolescents are well established. Multi-level interventions may be especially effective in establishing and sustaining health-enhancing behaviors. This study explored the influences of a multi-level community intervention aimed at increasing physical activity among tweens (youth 9–13). Two Florida school districts far apart served as intervention and comparison sites in a quasi-experimental post-test design. Youth in grades 5 through 8 in the intervention community (n = 1,253) and comparison community (n = 866) completed an anonymous post-intervention survey. An intent-to-treat analysis did not show any statistically significant group differences for the physical activity outcomes examined. However, a subset analysis revealed that students who reported participating in the intervention were more likely to be physically active than youth in the comparison group, as well as youth in the intervention community who reported not participating. Participating in the intervention was significantly related to meeting recommendations for vigorous physical activity (OR = 2.08, P = 0.0259), being physically active on weekends (OR = 1.84, P = 0.0017), and reporting more days of trying a new game or sport (OR = 1.49, P = 0.046) after controlling for grade, gender, race/ethnicity, and SES. These findings support the efficacy of multi-level interventions to create effective health behavior change, especially when linkages among community, media, schools, and the home are present.     

How business professionals view their stress.

Differences in stress for business professionals by sex, age, marital status, stress levels, job classification, having children and pets were investigated. Subjects were 80 business professionals who responded to the Tennessee Stress Scale-L inventory which provides three subscales (Stress Producers, Coping Mechanisms, and Stress Symptoms) and Total Stress. Significant differences were found between 40 men and 40 women and among stress level groups on Stress Producers, Stress Symptoms, and Total Stress scores.
