Faith-Based Sex Education Programs: What They Look Like and Who Uses Them

The purpose of this study was to explore the kinds of sex education programs for youth available in mainline churches. This research project sought to identify the kinds of programs developed, the ages of the youth involved, the reasons for implementing the programs, the goals of the programs, the topics covered, and the perceived youth response to these programs as identified by youth ministers and leaders. The sample included 92 churches/synagogues with memberships over 300 that were within a 25-mile radius of our small, urban area in southeast Michigan. Findings from this study lay the groundwork for exploring whether these programs have an impact on adolescents’ sexual behaviors.     

The Moderating Effects of Dispositional Affectivity on Performance and Task Attitudes in a Goal‐Setting Context1

This study examined the effects of goal difficulty, negative affectivity (NA), and positive affectivity (PA) on performance and task attitudes on a complex task. Research participants played an air traffic controller (ATC) simulation and were assigned either an easy or difficult goal at 2 different points in time: early during skill acquisition, and after several experimental trials. We hypothesized that the effect of difficult goals would vary depending on whether they were administered early and late during skill acquisition. We also hypothesized that NA and PA would moderate the effect of goal difficulty. Neither the early nor late goal assignments related to performance or task attitudes as hypothesized. Instead, PA and NA both moderated goal‐outcome relationships.     

The Interactive Effects of Dispositional Affectivity, Sex, and a Positive Mood Induction on Student Evaluations of Teachers

This study was designed to examine the effects of disposition, sex, and a positive mood induction on student evaluations of teachers. In 33 laboratory classes, 339 students filled out measures of negative affectivity (NA) and positive affectivity (PA). Several weeks later, participants filled out a research-based teacher evaluation form. Students in half of the classes received a positive mood induction prior to filling out the evaluation form, whereas participants in the other classes received the positive mood induction after filling out the evaluation form. Results indicated that PA and the positive mood induction both related positively with evaluation measures. Moreover, NA and PA moderated the relationship between the positive mood induction and teacher evaluations for males, but not for females. Implications for organizations and suggestions for future research are discussed.     

Associations between respiratory sinus arrhythmia reactivity and internalizing and externalizing symptoms are emotion specific

Internalizing and externalizing disorders are often, though inconsistently in studies of young children, associated with low baseline levels of respiratory sinus arrhythmia (RSA). RSA is thus considered to reflect the capacity for flexible and regulated affective reactivity and a general propensity for psychopathology. However, studies assessing RSA reactivity to emotional challenges tend to report more consistent associations with internalizing than with externalizing disorders, although it is unclear whether this is a function of the type of emotion challenges used. In the present study, we examined whether baseline RSA was associated with internalizing and/or externalizing severity in a sample of 273 young children (ages 5–6) with elevated symptoms of psychopathology. Following motivation-based models of emotion, we also tested whether RSA reactivity during withdrawal-based (fear, sadness) and approach-based (happiness, anger) emotion inductions was differentially associated with internalizing and externalizing symptoms, respectively. Baseline RSA was not associated with externalizing or internalizing symptom severity. However, RSA reactivity to specific emotional challenges was associated differentially with each symptom domain. As expected, internalizing symptom severity was associated with greater RSA withdrawal (increased arousal) during fearful and sad film segments. Conversely, externalizing symptom severity was related to blunted RSA withdrawal during a happy film segment. The use of theoretically derived stimuli may be important in characterizing the nature of the deficits in emotion processing that differentiate the internalizing and externalizing domains of psychopathology.     

Examining the Incremental Validity and Adverse Impact of Cognitive Ability and Conscientiousness on Job Performance

Using archival data from a large home improvement organization, the current study examined the incremental validity of conscientiousness over cognitive ability in predicting different performance criteria. Also, the study examined the effects of conscientiousness and cognitive ability on adverse impact. Results indicated that conscientiousness provided incremental validity over cognitive ability in the prediction of several performance criteria. Specifically, conscientiousness had the highest increases in validity over cognitive ability in the prediction of contextual performance factors (e.g., contextual performance, customer service orientation, dealing with others). However, the addition of conscientiousness failed to ameliorate the adverse impact associated with cognitive ability. In addition, limitations of the study and future directions of research are addressed.     

Short-term limb immobilization affects motor performance

C. Ghez, J. Gordon, and M. R Ghilardi (1995; J. Gordon, M. R Ghilardi, & C. Ghez, 1995; R. L. Sainburg, M. R Ghilardi, H. Poizner, & C. Ghez, 1995) have found that proprio-ceptive deafferentation impairs feedforward and feedback mechanisms that control reaching movements. In the present study, the authors found immobilization-induced changes in limb kinematics, including joint motion, in 32 healthy participants who performed out-and-back movements before and after 0, 6, or 12 hr of immobilization of the left arm. Control participants did not undergo the arm immobilization procedure. Immobilization for 12 hr, but not 6 hr, caused trajectories with increased hand-path areas and altered interjoint coordination. The abnormalities were smaller in amplitude but similar in quality to those reported in deafferented patients (R. L. Sainburg et al.). In addition, movement onset point significantly drifted after immobilization. Thus, short-term limb disuse can affect interjoint coordination by acting on feedforward mechanisms. These behavioral alterations are potentially related to cortical plastic changes.     

Cueing the interpretation of a Necker Cube: a way to inspect fundamental cognitive processes

The term perceptual bistability refers to all those conditions in which an observer looks at an ambiguous stimulus that can have two or more distinct but equally reliable interpretations. In this work, we investigate perception of Necker Cube in which bistability consists of the possibility to interpret the cube depth in two different ways. We manipulated the cube ambiguity by darkening one of the cube faces (cue) to provide a clear cube interpretation due to the occlusion depth index. When the position of the cue is stationary the cube perceived perspective is steady and driven by the cue position. However, when we alternated in time the cue position (i.e. we changed the position of the darkened cube face) two different perceptual phenomena occurred: for low frequencies the cube perspective alternated in line with the position of the cue; however for high frequencies the cue was no longer able to bias the perception but it appears as a floating feature traveling across the solid with the cube whole perspective that returns to be bistable as in the conventional, bias-free, case.     

Positive Affectivity as a Moderator of the Objective-Task Characteristics/Perceived-Task Characteristics Relationship

Data from a randomized experimental study were used to examine whether the dispositions of negative affectivity (NA) and positive affectivity (PA) moderated the relationships between task enrichment, task perceptions (job scope), and task satisfaction. Participants performed tasks that were low, moderate, or high in terms of enrichment. Results of regression analyses show that the task-enrichment manipulations explained a greater proportion of variance in job scope and task satisfaction than did the dispositions. Furthermore, PA, but not NA, moderated the relationship between task enrichment and job scope. Consistent with previous theory and research, our findings suggest that dispositions may play a role in individuals' perceptions of situational characteristics, but only when such characteristics are ambiguous.
