Priming the semantic neighbourhood during the attentional blink.

<h4>Background</h4>When two targets are presented in close temporal proximity amongst a rapid serial visual stream of distractors, a period of disrupted attention and attenuated awareness lasting 200-500 ms follows identification of the first target (T1). This phenomenon is known as the...
