Response time latencies (the amount of time that elapses between the presentation of the stimulus on the screen and the pressing of a key on the keyboard) very reliably measure cognitive processing time, which is at the heart of the IAT.

After you have completed at least one IAT, consider what is being measured. Read the attached introduction to Greenwald et al. (1998) paper describing the method. You may have come away thinking that the method used on the IAT is not very reliable – you would be wrong. Response time latencies (the amount of time that elapses between the presentation of the stimulus on the screen and the pressing of a key on the keyboard) very reliably measure cognitive processing time, which is at the heart of the IAT.

But what is being measured? Don’t worry if your IAT said that you tend to favor one kind of people other another – that’s not exactly what is happening, and it doesn’t mean you are secretly a bigot or homophobic. The IAT seems to be an indication of how well a person knows certain associations (the A in IAT). Write a page (250 words, 12pt font, double spaced) about your observations and thoughts about the IAT using.
