言语工作记忆对视觉工作记忆的影响

工作记忆是当前认知心理学中的一个研究热点,而其言语子系统与视觉子系统之间的关系又是一个颇具争论性的问题。实验1、2采用双任务范式考察了言语工作记忆对视觉工作记忆的影响。结果发现,满负荷言语负载条件下的视觉记忆的成绩显著低于无言语负载条件。这表明,言语工作记忆影响了视觉工作记忆任务的完成。     

Can organizational justice mitigate the negative effects of shift work and fixed-term employment?

The present study examined whether organizational justice moderates the association of shift work and employment type with patient-related stress, stress symptoms, and musculoskeletal symptoms. Cross-sectional survey data from 1270 Finnish female elderly care staff aged 18–69 years was used. Analyses of covariance were used to examine the associations adjusted for age,marital status, education, and tenure. Organizational justice was associated with lower levels of patient-related stress, stress symptoms, and musculoskeletal symptoms. Organizational justice mitigated stress symptoms related to working night shift and three shifts. In addition, organizational justice mitigated the patient-related stress associated with working on fixed-term contracts. Organizational justice was also able to alleviate musculoskeletal symptoms associated with working on permanent contracts. Thus, we found evidence for organizational justice being able to mitigate the negative effects of shift work and employment type. Promoting organizational justice in organizations with shift work and lots of fixed-term contracts is of importance.     

上下意象图式向抽象概念映射的心理现实性研究

通过考察上下意象图式隐喻的映射机制和形成机制,验证其向抽象概念的映射具有心理现实性.实验一中,学龄期儿童阅读与图式一致材料反应时,较阅读与图式不一致材料反应时短,说明上下意象图式存在于概念水平,并在即时阅读中被激活.实验二中,学龄前幼儿表现出物品摆放的上下方位偏好差异,表明幼儿在概念形成过程中,抽象概念与空间上下方位存在体验性联结.研究证明:部分抽象概念表征具有上下方位线索,人们借助上下意象图式建构抽象概念.     

The Effects of Cueing Target Location and Response Mode on Interference and Negative Priming Using a Visual Selection Paradigm

Two experiments are reported that examine the effects of cueing the location of a target in the prime display on interference and subsequent negative priming. The prime and probe displays comprised two words, a target and a distractor. In the prime display, the two words were either the same (response compatible) or different (response incompatible). The target in the probe display was unrelated to the prime distractor (control), the same word as the distractor (ignored repetition), or semantically related to the distractor (ignored semantic repetition). In Experiment 1, cueing the location of the prime target significantly reduced the interference effect but not the subsequent identity negative priming (NP) effect. In contrast, not cueing the prime target resulted in the elimination of the identity NP. There was no evidence of semantic NP in this experiment. In Experiment 2, where a categorization response was required, significant interference was obtained in the prime display that was not influenced by cueing the location of the target. Although there was significant semantic NP, identity NP failed to reach significance. The two experiments were analysed together, and findings are discussed in relation to current models of negative priming.
