Figure 1
Illustration of the stimulus sequence in Experiment 1. The first target (T1) was a Landholt C and subjects had to determine whether it was open to the left or right. The second target (T2) was the only boldfaced stimulus in the stream. The response feature of T2 (identity or color) was manipulated between subjects.
Figure 2
Average T2 accuracy rates, for correct T1 responses, as a function of task and T1–T2 lag in Experiment 1. The AB was deeper in the report-identity than in the report-color task. Error bars denote between-subject standard errors.
Table 1
Mean percentage of correct responses to T1 in Experiments 1–2, as a function of task and T1–T2 Lag (standard errors are presented in parentheses). Standard errors are between subjects in Experiment 1 and within subject (Morey, 2008) in Experiment 2.
| Report-color | Report-identity | |||
|---|---|---|---|---|
| Lag 3 | Lag 7 | Lag 3 | Lag 7 | |
| Experiment 1 | 91.0 (2.3) | 89.6 (2.6) | 91.9 (1.7) | 90.8 (2.3) |
| Report-color | Report-category | |||
| Lag 3 | Lag 7 | Lag 3 | Lag 7 | |
| Experiment 2 | 93.3 (0.7) | 93.0 (0.9) | 90.9 (1.0) | 91.1 (1.0) |
Figure 3
Schematic illustration of the sequence of events in Experiment 2. The first target (T1) was a gray string of eight repetitions of the same digit, and subjects had to determine whether this digit was smaller or larger than 5. The second target (T2) was the only boldfaced stimulus in the stream. The response feature of T2 (category or color) was manipulated within subjects. The actual stimuli were written in Hebrew.

Results of Experiment 2. Average T2 accuracy rates for correct T1 responses, as a function of task and T1–T2 lag. The AB was larger in the report-category than in the report-color task. Error bars denote within-subject standard errors (Morey, 2008).
