Clicking on the ‘Reveal discussion’ link will include a graph, Figure 3. This figure is a bar-graph with ‘Type of word’ on the horizontal axis and ‘time’ in milliseconds on the vertical axis, starting with minus 120 milliseconds at the bottom moving to plus 20 milliseconds at the top moving in increments of 20 milliseconds.

The graph shows two pairs of bars. The two left hand bars represent ‘Positive’ type of word and the two on the right represent ‘Negative’ type of word. The bars are colour coded blue for ‘black photo’ and yellow for ‘white photo’ as indicated in the key at the top of the graph.

For a positive word and a black photo the mean facilitation score is approximately minus 110 milliseconds. For a positive word and a white photo the mean facilitation score is approximately minus 45 milliseconds. For a negative word and a black photo the mean facilitation score is approximately plus 10 milliseconds. For a negative word and a white photo the mean facilitation score is approximately minus 25 milliseconds.
