TL;DR: It is shown that the type of stimulus used in rapid serial visual presentation streams has a significant effect on the extent of lag-1 sparing, without a commensurate influence on the AB, and that multiple consecutive targets produce strikingly different patterns of sparing for objects and letters.
Abstract: In a typical attentional blink (AB) experiment, recognition of the second of two serially presented targets is impaired if it occurs around 200-500 ms after the first. However, recognition for the second item is often intact if the two targets occur consecutively (lag-1 sparing). Recent theories of the AB have placed great emphasis on the presence of lag-1 sparing and protracted sparing effects, where accurate performance is seemingly maintained across three or more targets, provided that they are presented consecutively. Here, we show that the type of stimulus (objects vs. letters) used in rapid serial visual presentation streams has a significant effect on the extent of lag-1 sparing, without a commensurate influence on the AB. In addition, multiple consecutive targets produce strikingly different patterns of sparing for objects and letters. These findings suggest that the processes mediating lag-1 sparing are independent of those underlying the AB.

TL;DR: Results show that selective attention to modalities increases over this age range, and showed an increasing tendency to occur between 8 and 26 weeks of age.
Abstract: This study examined the effect of level of attention engagement on the modification of the blink reflex in young infants. Infants at 8, 14, 20, or 26 weeks of age were presented with interesting visual or auditory stimuli. At delays defined by changes in heart rate known to be associated with sustained attention or attention disengagement, blink reflexes were elicited by visual or auditory blink reflex stimuli. Blink amplitude varied according to the level of attention, and the match between the foreground and blink reflex stimulus. If the infant was attending to the foreground stimulus, a blink reflex stimulus in the same modality resulted in enhanced blink reflex magnitude. A blink reflex stimulus in the other modality resulted in an attenuated blink reflex magnitude. If attention was not engaged with the foreground stimulus, this modulation of the blink reflex did not occur. This ‘selective modality effect’ showed an increasing tendency to occur between 8 and 26 weeks of age. These results show that selective attention to modalities increases over this age range.

TL;DR: It is questioned whether the RSVP images can elicit a response in adolescent sexual offenders indicative of DSI, and the clinical utility of applying theRSVP assessment with adolescents rather than adults is queried.
Abstract: Attentional bias toward child images is assessed among adolescent sexual offenders and nonsexual offenders using the rapid serial visual presentation (RSVP) method, which measures the effects of “attentional blink.” Twenty adolescent sexual offenders against children and 26 nonsexual offenders are asked to identify a child or animal image and then a second image in streams of 10 images. A stronger attentional blink effect is expected for offenders against children after viewing child rather than animal images. However, the expected differences between offender groups are not found. It is questioned whether the RSVP images can elicit a response in adolescent sexual offenders indicative of DSI. The clinical utility of applying the RSVP assessment with adolescents rather than adults is also queried because (a) adolescents' cognitive abilities may not allow them to conceptualize and concentrate on the assessment in its present form and (b) deviant sexual interest may be evident to different degrees in adolesc...

TL;DR: Results suggest that early increase in sensory processing at the EPN level for negative words is not automatic, but bound to specific combinations of low-level features, occurring presumably via attentional control processes.
Abstract: Processing affectively charged visual stimuli typically results in increased amplitude of specific event-related potential (ERP) components. Low-level features similarly modulate electrophysiological responses, with amplitude changes proportional to variations in stimulus size and contrast. However, it remains unclear whether emotion-related amplifications during visual word processing are necessarily intertwined with changes in specific low-level features or, instead, may act independently. In this pre-registered electrophysiological study, we varied font size and contrast of neutral and negative words while participants were monitoring their semantic content. We examined ERP responses associated with early sensory and attentional processes as well as later stages of stimulus processing. Results showed amplitude modulations by low-level visual features early on following stimulus onset - i.e., P1 and N1 components -, while the LPP was independently modulated by these visual features. Independent effects of size and emotion were observed only at the level of the EPN. Here, larger EPN amplitudes for negative were observed only for small high contrast and large low contrast words. These results suggest that early increase in sensory processing at the EPN level for negative words is not automatic, but bound to specific combinations of low-level features, occurring presumably via attentional control processes.
