Extreme Response Style and the Measurement of Intra-Individual Variability in Affect

Extreme response style (ERS) has the potential to bias the measurement of intra-individual variability in psychological constructs. This paper explores such bias through a multilevel extension of a latent trait model for modeling response styles applied to repeated measures rating scale data. Modeling responses to multi-item scales of positive and negative affect collected from smokers at clinic visits following a smoking cessation attempt revealed considerable ERS bias in the intra-individual sum score variances. In addition, simulation studies suggest the magnitude and direction of bias due to ERS is heavily dependent on the mean affect level, supporting a model-based approach to the study and control of ERS effects. Application of the proposed model-based adjustment is found to improve intra-individual variability as a predictor of smoking cessation.     

Discouraging unethicality versus encouraging ethicality: Unraveling the differential effects of prevention‐ and promotion‐focused ethical leadership

Theory on the impact of ethical leadership has traditionally been based on a deontological approach to morality. Underlying this perspective is the assumption that all leader behaviors that encourage “normatively appropriate conduct” will influence followers in a similar fashion. Put differently, the current consensus seems to suggest that actions that focus on preventing unethical behavior—attending to “the wrong”—will have the same impact as actions that focus on promoting ethical behavior—attending to “the right.” Taking a within‐person approach, we draw upon social exchange theory to challenge this consensus and build theory that suggests a follower's felt trust from their leader will be differentially impacted by prevention‐ versus promotion‐focused ethical leadership. We also explore how these different types of ethical leadership may indirectly, through felt trust, impact citizenship behavior and counterproductive work behavior. Finally, we consider how the role of the “moral manager” may interact with the “moral person” by identifying leader moral hypocrisy as an important between‐person moderator of these effects. Given the importance of ethical decision‐making in organizations and the calls for increased ethical leadership, our findings have important implications for both theory and practice.     

Different coordination and flexibility of the spine and pelvis during lateral bending between young and older adults

This study examined coordination of the spine and pelvis during lateral bending of the trunk in older adults. Thirty-four healthy subjects (17 young and 17 older adults) demonstrated lateral bending at a controlled speed while holding a bar at approximately 180 degrees of shoulder flexion. Kinematic data collection was completed on the thoracic spine, lumbar spine, and pelvis. The coupling angle was calculated to examine the thorax–lumbar, lumbar–pelvis, and thorax–pelvis coordination patterns. The older adults demonstrated a reduced range of motion (ROM) of the lumbar spine, while both groups revealed similar ROM in the thorax and in the pelvis. The coupling angle between the straightening and bending phases was different only for the older adults in the thorax–lumbar (23.4 ± 8.0 vs. −1.6 ± 4.4, p = 0.004) and the lumbar–pelvis (65.4 ± 7.2 vs. 86.1 ± 7.8, p = 0.001) coordination. However, there was no group difference in the thorax–pelvis coordination. These findings indicate that age-related changes in the lumbar region affect coordination patterns only during the bending phase. The older adults preserved a similar pattern of movement to the young adults during the straightening phase, but the coordination variability of the coupling angles was greater for the older adults than for the young adults. This movement pattern suggests that the older adults lacked consistent trunk control in an attempt to optimize lateral bending coordination.     

EXTENDING THE GLOBAL ACADEMIC TABLE: AN INTRODUCTION

Before commenting on the papers from a recent interdisciplinary gathering of scholars from China, Japan, Korea, and Taiwan, a case is made for regional academia conversations today, because international conferences, especially in the humanities and social sciences, are still dominated by “Western” traditions, discourse, and protocols. After touching on the relative stability or variability of phenomena and procedures in the natural sciences, humanities, and social sciences, political and cultural questions are considered along with some of the ongoing consequences of the East Asian adoption of the European model of the modern research university.     

Experiences of father carers of children with Autism Spectrum Disorder: An exploratory study

This study aimed to explore the carer experiences of fathers of children with Autism Spectrum Disorder (ASD). A total of eight South African fathers between the ages of 38 and 45 years were the interview informants. They cared for at least one child with ASD each and their children with ASD were within the age range of five to nine years (n=9, males=7, females=2, Low functioning=4, Moderately functioning=4, High functioning=1).The father carers completed a semi-structured interview. The data were analysed thematically. Four primary themes emerged from the analysis pertaining to aspects of rescoping their futures to include the care of a child with ASD, relationship issues, access to and management of resources, information and support, and carer compassion and satisfaction. The fathers shared a view that caring for their children with ASD was both stimulating and enriching, and that with time, they were able to adapt, and better respond, to the specific needs of their child.     

When repeating aloud enhances episodic memory for spoken words: interactions between production- and perception-derived variability

We demonstrate that the phonetic detail of an original speaker’s pronunciation for a word can be detected with a memory measure even when a participant listens to and then repeats that word aloud (production). At study, native English participants heard English words pronounced by a native speaker of American-English or by a Chinese national. For half of the words they listened. For the others, they produced it. In both recall and old/new recognition tests in Experiment 1, production improved performance relative to listening alone. Effects of accent were present only in recognition and only in interaction with production. In Experiment 2, a source-monitoring recognition test where participants identified whether the speaker of a word changed from study to test, effects of accent and production were additive indicating that hearing an unfamiliar accent increased memory irrespective of production. An exemplar account including both production- as well as perception-derived experience describes the outcome.     

The distribution matters: two types of sample-size tasks

Different studies on how well people take sample size into account have found a wide range of solution rates. In a recent review, Sedlmeier and Gigerenzer (1997) suggested that a substantial part of the variation in results can be explained by the fact that experimenters have used two different types of sample-size tasks, one involving frequency distributions and the other sampling distributions. This suggestion rested on an analysis of studies that, with one exception, did not systematically manipulate type of distribution. In the research reported in this paper, well-known sample-size tasks were used to examine the hypothesis that frequency distribution versions of sample-size tasks yield higher solution rates than corresponding sampling distribution versions. In Study 1, a substantial difference between solution rates for the two types of task was found. Study 2 replicated this finding and ruled out an alternative explanation for it, namely, that the solution rate for sampling distribution tasks was lower because the information they contained was harder to extract than that in frequency distribution tasks. Finally, in Study 3 an attempt was made to reduce the gap between the solution rates for the two types of tasks by giving participants as many hints as possible for solving a sampling distribution task. Even with hints, the gap in performance remained. A new computational model of statistical reasoning specifies cognitive processes that might explain why people are better at solving frequency than sampling distribution tasks.

The Dynamics of Personality Approach (DPA): 20 Tenets for Uncovering the Causal Mechanisms of Personality

Over the last few decades, most personality psychology research has been focused on assessing personality via scores on a few broad traits and investigating how these scores predict various behaviours and outcomes. This approach does not seek to explain the causal mechanisms underlying human personality and thus falls short of explaining the proximal sources of traits as well as the variation of individuals' behaviour over time and across situations. On the basis of the commonalities shared by influential process-oriented personality theories and models, we describe a general dynamics of personality approach (DPA). The DPA relies heavily on theoretical principles applicable to complex adaptive systems that self-regulate via feedback mechanisms, and it parses the sources of personality in terms of various psychological functions relevant in different phases of self-regulation. Thus, we consider personality to be rooted in individual differences in various cognitive, emotional–motivational, and volitional functions, as well as their causal interactions. In this article, we lay out 20 tenets for the DPA that may serve as a guideline for integrative research in personality science. © 2020 The Authors.
