“…To be more confident in concluding higher levels of social vigilantism are related to counterarguing against attitude-incongruent positions, future research could also assess whether higher levels of social vigilantism are associated with paying more attention to attitude-incongruent information. For example, eye movement or eye blink measures (e.g., Nakano et al, 2009 ; Andreu-Sánchez et al, 2021a , b ) would be more direct measures of attention.…”

When people see political advertisements on a polarized issue they take a stance on, what factors influence how they respond to and remember the adverts contents? Across three studies, we tested competing hypotheses about how individual differences in social vigilantism (i.e., attitude superiority) and need for cognition relate to intentions to resist attitude change and memory for political advertisements concerning abortion. In Experiments 1 and 2, we examined participants’ intentions to use resistance strategies to preserve their pre-existing attitudes about abortion, by either engaging against opposing opinions or disengaging from them. In Experiment 3, we examined participants’ memory for information about both sides of the controversy presented in political advertisements. Our results suggest higher levels of social vigilantism are related to greater intentions to counterargue and better memory for attitude-incongruent information. These findings extend our understanding of individual differences in how people process and respond to controversial social and political discourse.

“…In primates, including human, eye blink rate has been shown to be associated with attention, cognitive engagement and performance of complex behaviors (Jongkees and Colzato 2016;Ranti et al 2020;Andreu-Sánchez et al 2021;Dave et al 2021). Central dopaminergic inputs to the frontal cortex and basal ganglia modulate voluntary and spontaneous eye blink mechanisms during cognitive processes (Maffei and Angrilli 2018;Pajkossy et al 2018;Imburgio et al 2021).…”

Rationale Dopamine (DA) signaling through the D1 receptor has been shown to be integral to multiple aspects of cognition, including the core process of working memory. The discovery of positive allosteric modulators (PAMs) of the D1 receptor has enabled treatment modalities that may have alternative benefits to orthosteric D1 agonists arising from a synergism of action with functional D1 receptor signaling. Objectives To investigate this potential, we have studied the effects of the novel D1 PAM DPTQ on a spatial delayed response working memory task in the rhesus monkey. Initial studies indicated that DPTQ binds to primate D1R with high affinity and selectivity and elevates spontaneous eye blink rate in rhesus monkeys in a dose-dependent manner consistent with plasma ligand exposures and central D1activation. Results Based on those results, DPTQ was tested at 2.5 mg/kg IM in the working memory task. No acute effect was observed 1 h after dosing, but performance was impaired 48 h later. Remarkably, this deficit was immediately followed by a significant enhancement in cognition over the next 3 days. In a second experiment in which DPTQ was administered on days 1 and 5, the early impairment was smaller and did not reach statistical significance, but statistically significant enhancement of performance was observed over the following week. Lower doses of 0.1 and 1.0 mg/kg were also capable of producing this protracted enhancement without inducing any transient impairment. Conclusions DPTQ exemplifies a class of D1PAMs that may be capable of providing long-term improvements in working memory.

“…Similarly, it is not obvious why a blink modulation is observed around perceptual switches of ambiguous stimuli where perception is not based on external sensory changes (Brych, Murali, & Händel, 2021b;Ito et al, 2003; van Dam & van Ee, 2005, 2006. Recent work suggests that indeed the content of information is more relevant for modulating blinking than the visual input specifics (Andreu-Sánchez, Martín-Pascual, Gruart, & Delgado-García, 2021). The presented visual and auditory studies on ambiguous percept serve to understand the function of spontaneous blink reduction.…”

Spontaneous Eye Blinks Map the Probability of Perceptual Reinterpretation During Visual and Auditory Ambiguity

Spontaneous eye blinks are modulated around perceptual events. Our previous study, using a visual ambiguous stimulus, indicated that blink probability decreases before a reported perceptual switch. In the current study, we tested our hypothesis that an absence of blinks marks a time in which perceptual switches are facilitated in‐ and outside the visual domain. In three experiments, presenting either a visual motion quartet in light or darkness or a bistable auditory streaming stimulus, we found a co‐occurrence of blink rate reduction with increased perceptual switch probability. In the visual domain, perceptual switches induced by a short interruption of visual input (blank) allowed an estimate of the timing of the perceptual event with respect to the motor response. This provided the first evidence that the blink reduction was not a consequence of the perceptual switch. Importantly, by showing that the time between switches and the previous blink was significantly longer than the inter‐blink interval, our studies allowed to conclude that perceptual switches did not happen at random but followed a prolonged period of nonblinking. Correspondingly, blink rate and switch rate showed an inverse relationship. Our study supports the idea that the absence or presence of blinks maps perceptual processes independent of the sensory modality.
