Recent studies demonstrating that multiple meanings of an ambiguous word are initially accessed even when only one reading is syntactically appropriate with the preceding context can be criticized on at least two grounds. First, many of the syntactic contexts used were not truly restrictive, and, secondly, subjects may not have had time to integrate the context before processing the ambiguous word. In the present study, subjects listened to a sentence ending in an ambiguous word and then made a lexical decision to a target related to either the appropriate or inappropriate reading. Contexts were completely restrictive, and a pause was introduced between the context and the ambiguous word. Multiple access still obtained, providing further support for the claim that lexical access is not guided by syntactic context. 相似文献

This study examined information communication technologies and workplace friendship dynamics. Employees reported factors that influenced their initiation of friendship with a coworker and reported patterns and perceptions of communication with their workplace friend via different communication methods. Results indicated that personality, shared tasks, and perceived similarity are the most important factors to coworker friendship initiation, and the importance of physical proximity to workplace friendship is diminishing in the electronically connected workplace. Results confirm the primacy of face‐to‐face interaction for workplace friendship initiation and maintenance. E‐mail, phone, and texting were also central to communication among workplace friends. The amount of time spent telecommuting affected workplace friendship initiation and communication. Finally, generational differences were identified with respect to Internet‐based communication methods. 相似文献

The purpose of this paper is to study the convergent validity of the four most widely used burnout measures in a sample of Chinese nurses (N= 717). First, Structural Equation Modeling was used to investigate the factor structure of scores produced by the Maslach Burnout Inventory‐General Survey (MBI‐GS), the Burnout Measure (BM), the Shirom‐Melamed Burnout Measure (SMBM), and the Oldenburg Burnout Inventory (OLBI). Next, several competing models were tested to investigate the convergent validity of these four burnout instruments. The final results suggest that burnout is best conceived of as a multidimensional construct consisting of exhaustion and withdrawal, which are two related but conceptually distinct aspects. In addition, positively phrased items should be dropped from burnout measures for they constitute a separate factor that is considered to be an artifact. 相似文献
