摘要: Frick成功地增加了混合通道的广度,其必要条件是同时呈现视觉刺激和反序报告。该文采用干扰更少的Corsi视空间测验,即序列呈现视觉刺激,并用正序报告,进行混合广度的新实验。发现在分离通道报告的条件下其混合广度都明显地高于单一通道的广度,因此Frick的两个必要条件不总是必需的。这种新的混合广度实验可能对研究工作记忆的中央执行系统有益。比较了刺激呈现模式和被试反应方式对混合广度的影响

Abstract: Frick (1984) found that using both an auditory and a visual short-term store increased digit span, but only under conditions that the visual stimuli were simultaneously presented, and the report order was inverted. ln the present new 4 experiments Corsi ' s Block tapping in which the stimuli were serially displayed and auditory digits were used to measure the mixed-modality span under normal report- Order Condition. lt is clear that the mixed-mode span was significantly higher than digit span or Corsi ' s span in Experiments 1, 2, and 4 and it is higher than that of Frick, s, it suggested that the two necessary conditions in Frick ' s experiments were not always needed and the new method may he useful for exploring the central executive of Working memory The effects of patterns of display of the stimuli of two modalities and the manner of report (separated vs mixed modalities) were compared.

Key words: mixed-modality span, working memory, central executive system, pattent of presentation of stimuli, manner of report
