TL;DR: The results show that the LVF advantage disappeared when involvement of stimulus‐driven spatial orienting was eliminated, whereas the manipulation of temporal attention had no effect on the asymmetry, and fit evidence that temporal attention is implemented by bilateral parietal areas and spatial attention by the right‐lateralized ventral frontoparietal network.

TL;DR: Three experiments used an emotion-induced blindness task to examine whether this prioritisation of emotional faces occurs in a purely stimulus-driven fashion or whether it emerges only when the faces are task-relevant, and found that reward-related faces impaired subsequent target identification.
Abstract: Facial emotion constitutes an important source of information, and rapid processing of this information may bring adaptive advantages. Previous evidence suggests that emotional faces are sometimes prioritised for cognitive processing. Three experiments used an emotion-induced blindness task to examine whether this prioritisation occurs in a purely stimulus-driven fashion or whether it emerges only when the faces are task-relevant. Angry or neutral faces appeared as distractors in a rapid serial visual presentation sequence, shortly before a target that participants were required to identify. Either the emotion (Experiment 1) or gender (Experiments 2 and 3) of the distractor face indicated whether a correct/incorrect response to the target would produce reward/punishment, or not. The three experiments found that reward-related faces impaired subsequent target identification, replicating previous results. Target identification accuracy was also impaired following angry faces, compared with neutral faces, demonstrating an emotion-induced attentional bias. Importantly, this impairment was observed even when face emotion was entirely irrelevant to the participants' ongoing task (in Experiments 2 and 3), suggesting that rapid processing of the facial emotion might arise (at least in part) from the operation of relatively automatic cognitive-perceptual processes.

TL;DR: The result indicates that failure to identify the target does nevertheless mobilize attentional resources sufficiently to prevent detection of a second target stimulus.
Abstract: The attentional blink has been attributed to capacity limitations at a central level of processing. We tested whether failure to identify the target would eliminate the blink. Two agnostic patients were presented with streams of letters, which they were able to identify, and streams of pictures, which they were unable to identify. The dual-task involved identification of a target and detection of a probe. With letters the duration of the blink was equivalent to that of the control subjects. A prolonged blink was observed in both patients for pictures irrespective of whether the target was identified. This result indicates that failure to identify the target does nevertheless mobilize attentional resources sufficiently to prevent detection of a second target stimulus.

TL;DR: The time course of semantic-only and associate–semantic priming effects during an AB task is examined, suggesting that priming in anAB task is driven by conceptual overlap facilitating lexical access at short SOAs and with longer SOAs lexicalAccess benefits from word associations links between targets.
Abstract: When two targets are presented using rapid serial visual presentation (RSVP) and the interval between the targets is 200-500 ms, report of the second target is impaired, a phenomena known as the attentional blink (AB). This study examined the time course of semantic-only and associate-semantic priming effects during an AB task. Three RSVP experiments were conducted using targets that shared either a semantic-only or an associative-semantic relationship. The results of the three experiments demonstrated semantic-only priming effects at the shortest stimulus onset asynchronies (SOAs). Associative-semantic priming was evident at shorter and longer SOAs. This suggests that priming in an AB task is driven by conceptual overlap facilitating lexical access at short SOAs and with longer SOAs lexical access benefits from word associations links between targets.

TL;DR: The findings show that some core emotional content is implicitly processed from the LSF of hybrid T1s since the effects on temporal selective attention are emotion specific.
