Power Differentials in Relationships

Abstract

The issue of sharing power affects many relationships. Many couple theorists and therapists believe that most marital distress is the result of power imbalances between the partners yet the influence of perceived power differentials in relationships is largely ignored in the therapy journals. The focus of this paper is on power differentials in couples. Different types of power are explored and assessment issues are examined. Therapeutic considerations are then presented and illustrated by case material. These issues are explored against a backdrop of gender sensitivity.     

Exploring the forgetting mechanisms in working memory: Evidence from a reasoning span test

In working memory (WM) span tests participants have to maintain to-be-remembered information while processing other, potentially distracting, information. Previous studies have shown that WM span scores are greater when span lists start with a long processing task and end with a short processing task than when these processing tasks are presented in the reverse order (e.g., Towse, Hitch, & Hutton, 2000). In Experiment 1, we obtained a similar stimulus order effect in a reasoning span test, using reasoning sentences that were equated for length in terms of the number of constituent words, but which differed in processing complexity; span scores were greater when lists began with a complex sentence and ended with a simple sentence than when this stimulus order was reversed. In Experiment 2, the stimulus order effect was not found when processing duration was held constant while sentence complexity was varied using a computer-paced moving window presentation paradigm. These results suggest that duration-based constraints can affect degree of forgetting independently of the load generated during processing phases in WM span performance and therefore imply that time-related forgetting can occur in WM span tests, particularly when the difficulty of the processing component blocks active maintenance of to-be-remembered material.     

Your words are my words: Effects of acting together on encoding

Social influences on action and memory are well established. However, it is unknown how acting together affects the incidental encoding of information. The present study asked whether coactors encode information that is relevant to a partner's task, but irrelevant to their own task. In Experiment 1, participants performed a categorization task alone and together, followed by a surprise free recall test where they were asked to recall items from the categorization task. Recall was better not only for items that participants had responded to themselves, but also for items that their coactor had responded to, than for items that had not required a response. The same results were found in Experiment 2, even though financial incentives motivated participants to only encode words they had responded to themselves. Together, the findings suggest that performing tasks together can modulate how information relevant to coactors is processed. Shared task representations may act as a vehicle for establishing shared memories.     

Networking In Organizations: Developing A Social Practice Perspective For Innovation And Knowledge Sharing In Emerging Work Contexts

This article focuses on the micro-level phenomena related to emergent ways of organizing. It explores how new ways of organizing might be enabled or inhibited through the networking activities and knowledge flows that organizational members engage in within a multinational business organization after the set-up of an innovative Internet business unit. The article considers innovation and networking as social practices mediated in this particular case study through knowledge-sharing activities. This perspective on innovation, networking, and knowledge leads to a conceptualization of organizations that stresses their inherent complexity and their interactive and co-evolving nature with their environments.     

The relation between social sharing and the duration of emotional experience

People often socially share their emotions to regulate them. Two-mode theory of social sharing states that cognitive sharing will contribute to emotional recovery, whereas socio-affective sharing will only temporarily alleviate emotional distress. Previous studies supporting this theory, measured emotional recovery in terms of residual emotional intensity. Until now, another important time-dynamic aspect of emotions, emotion duration, has been largely ignored. In two experience sampling studies we addressed this gap. In Study 1, participants reported on the duration of anger, fear, and sadness episodes; additionally time-varying information on the occurrence and mode of sharing was collected. This study revealed that sharing led to a shortening in emotion duration, in particular when it was socio-affective in nature. In Study 2 we investigated whether this result could be interpreted in terms of our measure of duration primarily reflecting emotional relief rather than recovery. In this study, the same method as in Study 1 was used; additionally, residual emotional intensity was measured three days after emotion onset. Study 2 largely replicated the findings from Study 1. Furthermore, duration appeared to be empirically distinct from residual intensity. Finally, no relation between sharing and residual intensity was found, even when considering the sharing mode.     

差异化变革型领导对知识分享与团队创造力的影响:社会网络机制的解释

差异化变革型领导是团队领导领域的最新议题,现有的研究局限于探讨其社会心理方面的作用机制。本文从社会网络机制出发解释差异化变革型领导对团队知识分享及团队创造力的影响。基于65家企业的225个工作团队样本的结构方程模型分析表明,团队一致性变革型领导正向影响团队交流网络密度从而提高团队知识分享;个体差异性变革型领导正向影响团队成员交流网络密度差异性从而降低团队知识分享;团队知识分享正向影响团队创造力。本文的证据表明,在中国情境下,差异性团队领导行为不利于创造稠密的团队交流网络,以及团队知识分享,从而不利于提升团队创造力水平。     

The psychological costs of knowledge specialization in groups: Unique expertise leaves you out of the loop

Knowledge specialization, such as that present in cross-functional teams, produces both positive and negative outcomes. Our research investigated how unique expertise can lead to feelings of ostracism in the form of being out of the loop. Compared to group members with shared expertise, members with unique expertise felt out of the loop and experienced decreased fulfillment of fundamental needs, particularly when their expertise was to be given less weight in the group’s decision. Possessing unique expertise did not inhibit leadership emergence, even when that expertise should not have been used in the decision-making process. So, although knowledge specialization can have positive consequences for teams and task performance, it also has some negative psychological consequences that need to be understood.     

Spatial correspondence between onsets and offsets of stimuli and responses

The Simon effect denotes faster responses when the task-irrelevant stimulus position corresponds to response position than when it does not. A common explanation is that a spatial stimulus code is formed automatically and activates a spatially corresponding response code. Previous research on stimulus–response (S–R) compatibility has focused on the ability to initiate movements to stimulus onsets. The present study investigates spatial-compatibility effects (i.e., the Simon effect) in the ability to initiate and to terminate actions both to stimulus onsets and to stimulus offsets. There were four major results. Firstly, offset stimuli produced normal Simon effects suggesting that stimulus offsets can automatically produce spatial codes. Secondly, onset stimuli produced larger Simon effects than offset stimuli, which is consistent with the attention-shift account of spatial coding. Thirdly, Simon effects were also observed in action termination. Fourthly, Simon effects in action initiation and in action termination were of similar size.     

SOCIAL SHARING IN ANTICIPATION OF CARDIAC SURGERY: WHO TALKS MORE AND WHY

This study presents the stress and sharing model, which was developed in order to predict the extent to which patients anticipating cardiac surgery, share their emotions. The model hypothesizes that preoperative sharing of emotions mediated by need, is positively related to surgery-related stress measured independently, and in comparison to the roommates. The model was tested for surgery-related and surgery-unrelated feelings. One hundred and fifty-seven Greek patients participated in the study. The variables included in the model were measured daily, using self-reports. Results show a good fit of the model only for surgery-related feelings (χ²=4.688, p=0.321). The study shows that patients anticipating surgery share their emotions in the same way as patients recovering from stressful or traumatic events. Stressed patients experience the need to focus on the threat (verbally) and not to be ‘distracted’ by talking about irrelevant topics. These findings have important implications for the design of preparatory interventions for surgical patients.     

Is the principle of minimization of secondary moments validated during various fingertip force production conditions?

During the application of fingertip forces with simultaneous flexion of the four fingers, namely index, middle, ring, and little fingers, a stable force sharing among fingers is adopted. Several studies have hypothesized that this stable force sharing is established to minimize unnecessary rotational moments (different from the main flexion moments). This principle labeled "minimization of secondary moments" is presented in the literature as a principle used by the central nervous system to solve musculoskeletal redundancy. However, this principle has only been tested with one solicited degree of freedom and in one finger posture. Our study tests this principle with various degrees of freedom solicited as secondary moments and in two different finger postures. Participants (n=6) were asked to apply a downward vertical force using their four fingers with the forearm placed in two different configurations: a "horizontal" condition (involving flexion/extension and pronation/supination at the wrist joint) and a "vertical" condition (involving flexion/extension and radial/ulnar deviation at the wrist joint). Additionally, two finger postures were tested in each forearm configuration: in the first, the distal inter-phalangeal joints (DIP) were extended and the proximal inter-phalangeal joints (PIP) highly flexed. In the second finger posture, both DIP and PIP joints were flexed. The resultant four-finger force and the relative involvement of each finger in the resultant four-finger force (force sharing) were analyzed. Results showed that the finger postures did not influence the finger force sharing, showing that the minimization of the secondary moment principle was stable among the finger joint angle configurations. Nonetheless, the relative involvement of each finger was dependent on the secondary degree of freedom solicited (pronation/supination vs. radial/ulnar). The modifications of the finger force sharing between the "horizontal" and "vertical" conditions were in accordance with the principle of minimization of the secondary moments.
