Does Bullying Affect Work-to-Private-Life Interference? Testing the Mediating Role of Resilience

Objectives. The present study, using the conservation of resources theory as a theoretical framework, aims to establish whether work-related bullying is associated with the development of two different types of work-to-private-life interference, i.e., time based and strain based. The study also aims to test whether these relationships are mediated by resilience. Method. In total, 333 nurses filled out a self-report questionnaire. Data analyses were performed by using structural equation model. Results. Results confirmed the hypothesized model: work-related bullying is associated with both strain-based and time-based work-to-private-life interferences. The bootstrap test indicated the presence of an indirect effect of bullying on both types of work-to-private-life interference via resilience. Originality/Value. The present study contributes to improve the understanding on the mechanisms linking work-related bullying and worker well-being, by providing evidence for the mediating role of resilience between bullying and both time-based and strain-based work–life interferences. Practical implications. The present study suggests that the intervention programs, in order to be effectiveness in sustaining work–life balance among nurses, should take into great account the social climate in the organizational context, e.g., the quality of the social climate with particular reference to the bullying prevention.     

Age-related changes in frequency of mind-wandering and task-related interferences during memory encoding and their impact on retrieval

During the performance of cognitive tasks such as memory encoding, attention can become decoupled from the external environment and instead focused on internal thoughts related to the appraisal of the current task (task-related interferences; TRI), or personal thoughts unrelated to the task at hand (mind-wandering; MW). However, the association between the frequency of these thoughts experienced at encoding and retrieval accuracy in young and older adults remains poorly understood. In this study young and older adults encoded lists of words using one of two encoding tasks: judging whether words are man-made/natural (objective task), or whether they are pleasant/neutral (subjective task). We measured the frequency of TRI and MW at encoding, and related them to retrieval accuracy in both age groups. We found that encoding task influenced the type of internal thoughts experienced by young, but not older, adults: young exhibited greater MW in the subjective vs the objective task, and greater TRI in the objective vs subjective encoding task. Second, across both tasks we found marked age-related decreases in both MW and TRI at encoding, and frequency of these thoughts negatively impacted memory retrieval in young adults only. We discuss these findings in relation to current theories of ageing, attention and memory.     

Testing improves true recall and protects against the build-up of proactive interference without increasing false recall

Retrieval practice has been shown to protect against the negative effects of previously learned information on the learning of subsequent information, while increasing retention of new information. We report three experiments investigating the impact of retrieval practice on false recall in a multiple list paradigm. In three different experimental designs participants studied blocks of interrelated words that converged on non-presented associates. Participants were tested either after every study block or only after the fifth study block, and both groups received a cumulative test on all five study blocks. Overall the results from all three different experimental designs point to a benefit of testing in increasing long-term veridical recall on the cumulative test. More importantly, this improvement in veridical recall did not come at a cost: False recall on the cumulative test did not increase from retrieval practice.     

Postsurgical physical activity and fatigue-related daily interference in women with non-metastatic breast cancer

Purpose: Women undergoing surgery for breast cancer experience side effects, such as fatigue, reduced quality of life (QOL) and depression. Physical activity (PA) is associated with improved psychological adjustment during treatment and survivorship, yet little is known about how PA relates to fatigue, depression and QOL in the period following surgery for breast cancer. The purpose of the study was to examine the relationships between these constructs in women who recently underwent surgery for breast cancer.

Methods: At 2–10 weeks post-surgery, 240 women with non-metastatic breast cancer reported intensity and duration of moderate and vigorous PA (MVPA), fatigue (intensity and interference), depressed mood, clinician-rated depression and functional QOL.

Results: In the path analysis models tested, women that reported greater weekly MVPA reported less fatigue interference, greater functional QOL, less depressed mood, and lower clinician-rated depression. Tests of indirect effects suggested that fatigue interference may be an intermediate pathway by which MVPA relates to functional QOL, clinician-rated depression and depressed mood.

Conclusion: Women who are more physically active in the months after breast cancer surgery show greater psychological adaptation in the initial phases of their treatment.     

Curvilinear relationship between phonological working memory load and social-emotional modulation

Evaluative conditioning refers to the changes in liking of an evaluatively neutral stimulus (the conditional stimulus or CS) as a result of merely pairing it with another, already liked or disliked stimulus (the unconditional stimulus or US). We examined whether other, non‐evaluative stimulus properties of a US can also be associatively transferred to a CS. In a series of experiments, we tried to transfer perceptions of the gender of children and the gender of first names. We found evidence for the associative transfer of these properties but only when participants were aware of the contingencies.     

Cognition and Emotion,Volume 24, 2010, List of Reviewers

The tendency for anxious individuals to selectively attend to threatening information is believed to cause and exacerbate anxious emotional responding in a self-perpetuating cycle. The present study sought to examine the relation between differential interoceptive conditioning (IC) using carbon dioxide inhalation as a panicogenic unconditioned stimulus (US) and the development of Stroop colour-naming interference to various non-word conditioned stimuli (CSs). Healthy university students (N = 27) underwent the assessment of colour-naming interference to reinforced CS+ and non-reinforced CS? non-words prior to and following differential fear conditioning. Participants showed greater magnitude electrodermal and verbal-evaluative responses to the CS+ over the CS? non-word following IC, and demonstrated the expected slower colour-naming latencies to the CS+ compared to the CS? non-word from baseline to post-conditioning. We discuss the relation between fear learning and the emergence of attentional bias for threat to further understand the maintenance of anxiety disorders.

Impaired inhibition of prepotent motor tendencies in Friedreich ataxia demonstrated by the Simon interference task

Friedreich ataxia (FRDA) is the most common of the genetically inherited ataxias. We recently demonstrated that people with FRDA have impairment in motor planning - most likely because of pathology affecting the cerebral cortex and/or cerebello-cortical projections. We used the Simon interference task to examine how effective 13 individuals with FRDA were at inhibiting inappropriate automatic responses associated with stimulus-response incompatibility in comparison with control participants. Participants had to respond to arrow targets according to two features which were either congruent or incongruent. We found that individuals with FRDA were differentially affected in reaction time to incongruent, compared with congruent stimuli, when compared with control participants. There was a significant negative correlation between age of onset and the incongruency effect, suggesting an impact of FRDA on the developmental unfolding of motor cognition, independent of the effect of disease duration. Future neuroimaging studies will be required to establish whether this dysfunction is due to cerebellar impairment disrupting cerebro-ponto-cerebello-thalamo-cerebral loops (and thus cortical function), direct primary cortical pathology, or a possible combination of the two.     

空白间隔对汉字知觉干扰效应的影响

采用辨认残缺汉字的方法考察空白间隔对汉字知觉干扰效应的影响。两个实验分别考察了空白间隔的长短和不同的插入位置对汉字知觉干扰效应的影响,结果发现:(1)适当长度的空白间隔(大于等于600ms)能导致干扰效应的消失;(2)该空白间隔的位置越接近递进进程最后阶段,残缺汉字的辨认成绩越好,越不容易出现干扰。实验结果支持竞争激活假说,不支持失匹配假说。
