Abstract

BACKGROUND: Inconsistent findings on coupled illumination, accumulated noise and task complexity effects on cognitive-motor performance asked for a more comprehensive analysis by focusing on performance dynamics. OBJECTIVE: The aim was to investigate the effects of illumination, accumulated noise, and task complexity on several average and non-average temporal indicators. METHODS: The research was designed as a mixed factorial quasi-experiment including 83 students of transport (n = 42) and psychology (n = 41) at the University of Zagreb. Participants were assigned to designated experimental conditions defined by illumination (40, 280, 3400 lx), and accumulated noise (0% and 50% of the daily exposure limit) levels and all performed 2- and 8-choice reaction time tests. RESULTS: The findings showed negative effects of accumulated noise and task complexity on all performance indicators, while the effect of illumination reached significance only for maximal speed. Significant Illumination x Task complexity and Illumination x Accumulated noise effects were obtained for average efficiency, while significant Accumulated noise x Task complexity effect was observed for average efficiency and maximal speed. CONCLUSIONS: Various indicators of performance dynamics were diversely affected by external factors, thereby suggesting the effects’ mechanisms, and accentuating different guidelines for design of workplaces that include these environmental stressors.

光照、累积噪声和任务复杂性对认知运动表现动力学的分离和耦合效应

背景:关于光照、累积噪音和任务复杂性对认知运动表现的影响的不一致的研究结果要求通过关注表现动力学进行更全面的分析。目的:研究光照、累积噪声和任务复杂度对几个平均和非平均时间指标的影响。方法:本研究采用混合因子准实验设计，包括萨格勒布大学交通运输专业(n = 42)和心理学专业(n = 41)的83名学生。参与者被分配到指定的实验条件，由照度(40、280、3400 lx)和累积噪音(每日暴露限值的0%和50%)水平定义，并进行2和8个选择的反应时间测试。结果:累积噪声和任务复杂度对所有性能指标均有负面影响，而光照仅对最大速度有显著影响。平均效率得到显著的光照×任务复杂度和光照×累积噪声效应，而平均效率和最大速度得到显著的累积噪声×任务复杂度效应。结论:绩效动态的各种指标受到外部因素的不同影响，从而提示了影响机制，并强调了包括这些环境压力因素的不同工作场所设计指南。

期刊介绍： Human Systems Management (HSM) is an interdisciplinary, international, refereed journal, offering applicable, scientific insight into reinventing business, civil-society and government organizations, through the sustainable development of high-technology processes and structures. Adhering to the highest civic, ethical and moral ideals, the journal promotes the emerging anthropocentric-sociocentric paradigm of societal human systems, rather than the pervasively mechanistic and organismic or medieval corporatism views of humankind’s recent past. Intentionality and scope Their management autonomy, capability, culture, mastery, processes, purposefulness, skills, structure and technology often determine which human organizations truly are societal systems, while others are not. HSM seeks to help transform human organizations into true societal systems, free of bureaucratic ills, along two essential, inseparable, yet complementary aspects of modern management: a) the management of societal human systems: the mastery, science and technology of management, including self management, striving for strategic, business and functional effectiveness, efficiency and productivity, through high quality and high technology, i.e., the capabilities and competences that only truly societal human systems create and use, and b) the societal human systems management: the enabling of human beings to form creative teams, communities and societies through autonomy, mastery and purposefulness, on both a personal and a collegial level, while catalyzing people’s creative, inventive and innovative potential, as people participate in corporate-, business- and functional-level decisions. Appreciably large is the gulf between the innovative ideas that world-class societal human systems create and use, and what some conventional business journals offer. The latter often pertain to already refuted practices, while outmoded business-school curricula reinforce this problematic situation.
