The Effect of Expectation and Temporal Attention on Visual Perception
Two experiments were undertaken to explore the interaction between temporal attention and expectations rooted in conditional probabilities concerning visual perception by using the attentional blink paradigm.The results showed that visual sensitivity was higher for expected stimuli whereas it was lower for unexpected stimuli when the stimuli were in the attentional blank phase compared to the neutral condition.Additionally,the decision criteria was lower for expected stimuli and the subjective visibility was higher for unexpected stimuli,regardless of whether the stimuli were in the blink phase or not.These findings provide support to a synergistic model of expectation and attention within the framework of predictive coding theory.
