TL;DR: Investigating whether RB is affected by online response selection, a cognitive operation that requires central processing, indicates that it does not result from central resource limitations, and indicates that temporal attentional limits to conscious perception can occur at multiple stages of information processing.
Abstract: Theattentional blink (AB) andrepetition blindness (RB) phenomena refer to subjects’ impaired ability to detect the second of two different (AB) or identical (RB) target stimuli in a rapid serial visual presentation stream if they appear within 500 msec of one another. Despite the fact that the AB reveals a failure of conscious visual perception, it is at least partly due to limitations at central stages of information processing. Do all attentional limits to conscious perception have their locus at this central bottleneck? To address this question, here we investigated whether RB is affected by online response selection, a cognitive operation that requires central processing. The results indicate that, unlike the AB, RB does not result from central resource limitations. Evidently, temporal attentional limits to conscious perception can occur at multiple stages of information processing.

TL;DR: The processing and clearance of information was largely preserved in nondemented Parkinson's patients, without evidence of bradyphrenia, and perseveration of earlier RSVP items in short-term memory was thought to explain the different pattern of errors.
Abstract: In healthy adults, deficits in identifying a second target following a previously attended target in Rapid Serial Visual Presentation (RSVP) occur between intertarget intervals of approximately 100-500 ms. This Attentional Blink (AB) is investigated in nondemented medicated Parkinson's patients using a modification of the standard paradigm that required the identification of two red letters embedded in a black letter distractor stream. Parkinson's patients and controls produced an equivalent AB, although with a different pattern of errors. Thus, the processing and clearance of information was largely preserved in nondemented Parkinson's patients, without evidence of bradyphrenia. However, perseveration of earlier RSVP items in short-term memory was thought to explain the different pattern of errors.

TL;DR: The importance for threat-prioritisation research to heed both the type of threat and prioritisation investigated is highlighted, as it is commonly assumed that threatening expressions are perceptually prioritised, possessing the ability to automatically capture and hold attention.
Abstract: It is commonly assumed that threatening expressions are perceptually prioritised, possessing the ability to automatically capture and hold attention. Recent evidence suggests that this prioritisation depends on the task relevance of emotion in the case of attention holding and for fearful expressions. Using a hybrid attentional blink (AB) and repetition blindness (RB) paradigm we investigated whether task relevance also impacts on prioritisation through attention capture and perceptual salience, and if these effects generalise to angry expressions. Participants judged either the emotion (relevant condition) or gender (irrelevant condition) of two target facial stimuli (fearful, angry or neutral) imbedded in a stream of distractors. Attention holding and capturing was operationalised as modulation of AB deficits by first target (T1) and second target (T2) expression. Perceptual salience was operationalised as RB modulation. When emotion was task-relevant (Experiment 1; N = 29) fearful expressions captured and held attention, and were more perceptually salient than neutral expressions. Angry expressions captured attention, but were less perceptually salient and capable of holding attention than fearful and neutral expressions. When emotion was task-irrelevant (Experiment 2; N = 30), only fearful attention capture and perceptual salience effects remained significant. Our findings highlight the importance for threat-prioritisation research to heed both the type of threat and prioritisation investigated.

TL;DR: It is demonstrated that attentional conditioned responses can occur without CA and advance the understanding of the mechanisms by which implicit conditioning can occur and becomes observable, which can highlight how addictive behaviours might develop.

TL;DR: This paper found that selective visual attention towards or away from climate-related information would be associated with climate concern, and the degree of selective inattention to climate related words correlated with self-rated climate concern.
Abstract: Despite the scientific consensus, there is widespread public controversy about climate change Previous explanations focused on interpretations hampered by political bias or insufficient knowledge of climate facts We propose that public views of climate change may also be related to an attentional bias at a more basic level of cognitive processing We hypothesized that selective visual attention towards or away from climate-related information would be associated with climate concern To test prioritization of climate-related stimuli under conditions of limited attention, we asked participants to identify climate-related and neutral words within a rapid stream of stimuli Undergraduate students attended to climate-related words more readily than neutral words This attentional prioritization correlated with self-rated climate concern We then examined this relationship in a more diverse community sample Principal component analysis of survey data in the community sample revealed a component indexing a relationship between climate concern and political orientation That component was correlated with the degree of selective inattention to climate-related words Our findings suggest that climate-related communications may be most effective if tailored in a manner accounting for how attentional priorities differ between audiences—particularly those with different political orientations
