The Astonishing Magic Of The LDK378
79, p?Quetiapine it is apparent in Fig. 3 (Bottom Panel), more first looks to color changes occurred earlier during scene viewing in the single-task condition compared to the dual-task condition. The effect of ordinal fixation position was significant for both the single-task condition, F (3,?33)?=?22.37, p?learn more p?=?.44, t (11)?=?1.00, p?=?.33, t (11)?=??.32, p?=?.75, respectively. While the frequency analysis above failed to produce a significant interaction of load and ordinal fixation position, the speed analysis showed a significant interaction of load and ordinal fixation position. This pattern suggests that the observers re-fixated the color change more often than the onset; however, as it will be reported in the later between-experiments analysis, this difference did not reach significance. These results indicate that, as in Experiment 1, color-induced oculomotor capture occurs slower under higher cognitive load. The results of Experiment 2 are consistent with those of Experiment 1. Both the likelihood and speed AG-014699 supplier of oculomotor capture in the face of sudden color changes were reduced in the dual-task condition. These results provide strong converging evidence that oculomotor capture in real-world scenes is not immune to observers�� cognitive load. To obtain a clearer picture of likelihood and speed of oculomotor capture caused by different types of visual events (i.e., a sudden appearance of a new object vs. an abrupt color change of the existing object in a scene), we conducted a mixed-model ANOVA that contrasted the patterns of results obtained in Experiments 1 and 2. A mixed-model ANOVA with within-subjects factors of load and ordinal fixation position and a between-subjects factor of change type (onset vs. color change) was conducted to determine whether the frequency of fixating the critical object varied as a function of load (single-task vs. dual-task), ordinal fixation position (Fixations 1�C4), and change type (onset vs. color change). The observers fixated the critical object more often when they were engaged in the viewing task only than when they were engaged in both the viewing and auditory tasks, F (1,?22)?=?35.81, p?
