详细信息----------Details----------
The mean interaction contrast (MIC) indicates the architecture of a process. Serial processes result in MIC equal to zero. Parallel-OR and Coactive process have a positive MIC. Parallel-AND process have a negative MIC. A test for a significant MIC can be done with a nonparametric adjusted rank transform test (described below) or an ANOVA.
的平均的相互作用对比度(MIC)表示的结构的一个过程。串行进程的结果在MIC等于零。并联或与共同作用的过程,有一个积极的MIC。并行和过程有负面的MIC。的重大MIC可以做的测试与调整后的非参数秩变换测试(如下所述)或方差分析。
The Adjusted Rank Transform is a nonparametric test for an interaction between two discrete variables. The test is carried out by first subtracting the mean effect of the salience level on each channel. Suppose, m_{H,\cdot} = E[RT; Level of Channel 1 is Fast], m_{L,\cdot} = E[RT; Level of Channel 1 is Slow], m_{\cdot, H} = E[RT; Level of Channel 2 is Fast], m_{\cdot, L} = E[RT; Level of Channel 2 is Slow]. Then for each response time from the fast–fast condition, m_{H, \cdot} and m_{\cdot,H} are subtracted. Likewise, for each of the other conditions, the appropriate m is subtracted. Next, each mean subtracted response time is replaced with its rank across all conditions (e.g., the fastest time of all conditions would be replaced with a 1). In this implementation, tied response times are assigned using the average rank. Finally, a standard ANOVA on the ranks is done on the ranks and the p-value of that test is returned. This test was recommended by Sawilowsky (1990) based on a survey of a number of nonparametric tests for interactions. He credits Reinach (1965) for first developing the test.
调整后的排名变换是一种非参数检验,两个独立的变量之间的相互作用。该测试是通过先减去在每个通道上的显着性水平的平均效果。假设,m_{H,\cdot} =E [RT通道1的水平是快速,m_{L,\cdot} =E [RT通道1的水平速度很慢,m_{\cdot, H} =E [RT通道2的水平快],m_{\cdot, L} =E [RT通道2级的速度很慢]。然后,对于每个响应时间快 - 快条件,m_{H, \cdot}和m_{\cdot,H}中减去。同样地,对于每个其他条件,适当的m减去。接下来,每个均值减去响应时间被替换其排名在所有条件下(例如,在最快的时间将被替换的所有条件,用1)。在此实现中,并列的响应时间被分配使用的平均等级。最后,标准方差分析的职级的职级,p值,则返回该测试。推荐Sawilowsky(1990)这个测试是根据一项调查显示,一些非参数检验的互动。他相信雷纳克(1965年),第一个开发测试。
