Effects of aging on action-intentional programming

Background: Action-intentional programs control “when” we initiate, inhibit, continue, and stop motor actions. The purpose of this study was to learn if there are changes in the action-intentional system with healthy aging, and if these changes are asymmetrical (right versus left upper limb) or related to impaired interhemispheric communication. Methods: We administered tests of action-intention to 41 middle-aged and older adults (61.9 ± 12.3 years). Results: Regression analyses revealed that older age predicted a decrement in performance for tests of crossed motor response inhibition as well as slower motor initiation with the left hand. Conclusion: Changes in action-intention with aging appear to be related to alterations of interhemispheric communication and/or age-related right hemisphere dysfunction; however, further research is needed to identify the mechanisms for age-related changes in the brain networks that mediate action-intention.     

Does Character Similarity Increase Identification and Persuasion?

The identity of protagonists in persuasive narratives was varied to test the impact of audience-character demographic similarity on identification. In Study 1, sex and nationality, both traits that were pretested to be important to participants’ self-identity, were varied, but demographic similarity did not increase perceived similarity, identification or persuasion. In Study 2, age and city of residence, traits that were central to the story, were varied, but again similarity on these demographic traits had no effects. Given previous research, these were surprising findings. The failure to find the expected effect of demographic similarity on identification and its implications for the understanding of the mechanisms underlying the development of identification are discussed within the framework of narrative response theory.     

Presurgery distress and specific response expectancies predict postsurgery outcomes in surgery patients confronting breast cancer.

Prior to scheduled surgery, patients frequently experience particularly high levels of distress and expect a variety of postsurgery symptoms. Surgery patients who confront breast cancer are no exception. It has been suggested that such presurgery distress and response expectancies are predictive of postsurgery outcomes. To test the contribution of presurgery distress and expectancies to common postsurgery symptom outcomes (pain, nausea, fatigue, and discomfort), 63 female patients undergoing breast cancer surgery were recruited to a prospective study. Results indicated that presurgery distress uniquely contributed to patients' postsurgery nausea, fatigue, and discomfort; specific expectancies uniquely contributed to pain intensity, pain unpleasantness, and fatigue (ps < .05). Consistent with expectancy theory, associations between response expectancies and postsurgery outcomes were not due to presurgery distress.     

Collective Efficacy as a Key Context in Neighborhood Support for Urban Youth

Neighborhood context, including the physical and social environment, has been implicated as important contributors to positive youth development. A transactional approach to neighborhood asserts that place and people are mutually constitutive; negative perceptions of place are intrinsically bound with negative portrayals of stigmatized groups, including youth. Adult perceptions of neighborhood youth may contribute to an increased sense of alienation and youth antisocial behavior. This study uses street‐intercept interviews with adults (N = 408) to examine the relationship between neighborhood conditions and adult support for neighborhood youth. A path model was used to examine the direct and indirect relationship of neighborhood constructs (safety, aesthetic quality, and walkability) on adult support for neighborhood youth. Neighborhood aesthetic quality and the walking environment were directly associated with adult support for youth, whereas perceived safety was indirectly associated. Collective efficacy partially explained these relationships. Findings support theorized relationships between people and places; improvements to neighborhood physical environment may directly impact resident adults’ perceptions of neighborhood young people.     

Attachment Theory and Affect Regulation: The Dynamics,Development, and Cognitive Consequences of Attachment-Related Strategies

Attachment theory (J. Bowlby, 1982/1969, 1973) is one of the most useful and generative frameworks for understanding both normative and individual-differences aspects of the process of affect regulation. In this article we focus mainly on the different attachment-related strategies of affect regulation that result from different patterns of interactions with significant others. Specifically, we pursue 3 main goals: First, we elaborate the dynamics and functioning of these affect-regulation strategies using a recent integrative model of attachment-system activation and dynamics (P. R. Shaver & M. Mikulincer, 2002). Second, we review recent findings concerning the cognitive consequences of attachment-related strategies following the arousal of positive and negative affect. Third, we propose some integrative ideas concerning the formation and development of the different attachment-related strategies.     

Teaching a simple meal preparation skill to adults with moderate and severe mental retardation using video modeling

We evaluated whether adults with mental retardation in the moderate or severe range would acquire simple meal preparation skills via video modeling. Training was conducted in the kitchen of the participants' day treatment setting. The intervention consisted of (i) watching a video of an adult with a developmental disability making a peanut butter and jelly sandwich and (ii) receiving verbal praise for each step of the task that was performed correctly. All three participants mastered the task and demonstrated generalization across settings. All three participants also demonstrated maintenance of the skill one month following mastery.

The role of executive function and social‐emotional skills in the development of literacy and numeracy during preschool: a cross‐lagged longitudinal study

The majority of evidence on the interplay between academic and non‐academic skills comes from high‐income countries. The aim of this study was to examine the bidirectional associations between Ghanaian children's executive function, social‐emotional, literacy, and numeracy skills longitudinally. Children (N = 3,862; M age = 5.2 years at time 1) were assessed using direct assessment at three time points over the course of two school years. Controlling for earlier levels of the same skill, early executive function predicted higher subsequent literacy and numeracy skills, and early literacy and numeracy skills predicted higher subsequent executive function, indicating that the development of executive function and academic skills is inter‐related and complementary over time. Early literacy and numeracy predicted subsequent social‐emotional skills, but early social‐emotional skills did not predict subsequent literacy and numeracy skills. The findings provide longitudinal evidence on children's learning and development in West Africa and contribute to a global understanding of the relations between various developmental skills over time.     

The Effects of Features of Survey Measurement on Self-Rated Health: Response Option Order and Scale Orientation

Self-rated health (SRH) is widely used to study health across a range of disciplines. However, relatively little research examines how features of its measurement in surveys influence respondents’ answers and the overall quality of the resulting measurement. Manipulations of response option order and scale orientation are particularly relevant to assess for SRH given the increasing prominence of web-based survey data collection and since these factors are often outside of the control of the researcher who is analyzing data collected by other investigators. We examine how the interplay of two features of SRH influence respondents’ answers in a 2-by-3 factorial experiment that varies (1) the order in which the response options are presented (“excellent” to “poor” or “poor” to “excellent”) and (2) the orientation of the response option scale (vertical, horizontal, or banked). The experiment was conducted online using workers from Amazon Mechanical Turk (N = 2945). We find no main effects of response scale orientation and no interaction between response option order and scale orientation. However, we find main effects of response option order: mean SRH and the proportion in “excellent” or “very good” health are higher (better) and the proportion in “fair” or “poor” health lower when the response options are ordered from “excellent” to “poor” compared to “poor” to “excellent.” We also see heterogeneous treatment effects of response option ordering across respondents’ characteristics associated with ability. Overall, the implications for the validity and cross-survey comparability of SRH are likely considerable for response option ordering and minimal for scale orientation.
