Visual selection for external stimuli, guided by a cue that prioritizes goal-related as well as feature matching stimuli, is modulated by stimulus onset asynchrony (SOA) after the cue. However, whether or not the modulation effect of SOA can occur when attention is directed to internal representations in working memory remains unclear. In two experiments, we explored the influences of SOA after a retrospective cue (retro-cue) that simultaneously incurs goal-directed and stimulus-driven priority on internal attention to working memory representations during orientation (Experiment 1) and color (Experiment 2) reproducing tasks.

The cognitive process underlying creative thinking is often conceptualized within a dual-state model, dividing it into generation and evaluation sub-processes. The generation process primarily involves the reorganization of existing knowledge to foster novel ideas, which are subsequently assessed for novelty and appropriateness during the evaluation process. Although these processes likely engage distinct cognitive components and neural mechanisms, there is a paucity of neuroimaging studies directly comparing them.

Cellulose is long-chain glucose polymer, which is linked by β-1,4-glycosidic bond. Its degradation relies on the synergistic action of multi-component cellulase system, including endoglucanase, exoglucanase and β-glucosidase. Cellulase hydrolyzes cellulose to produce glucose through the sequential reactions.

Compelling evidence indicated shared cognitive mechanisms underpinning attention in both the external and internal domains. Typically, both external attention and internal attention are vulnerable to biases from intended goals and stimulus features. However, it is still unclear whether the temporal characteristics of the relationship between goal-directed and stimulus-driven external attention could be observed in internal attention.

The visual perception system of humans is susceptible to cognitive influence, which implies the existence of cognitive perception. However, the specifical trigger for cognitive penetration is still a matter of controversy. The current study proposed that the cognitive processing priority over perceptual processing might be critical for inducing cognitive penetration.

Assertion is the use of declarative sentences to convey information, which necessitates meeting the "justified-belief norm" as a prerequisite. However, a significant amount of misinformation that did not meet these conditions was spread during COVID-19, leading to a reintroduction of the assertion norm. One possible hypothesis is that the threatening content of the misinformation influenced the perception of the norm.

Affective feelings naturally infuse individuals' perceptions, serving as valid windows onto the real world. The further explains how these feelings work: as properties of individuals' perceptual experiences, these feelings influence perception. Notably, this hypothesis based on affective feelings with different valences has been substantiated, whereas the existing evidence is not compelling enough.

When simultaneously confronted with multiple attentional targets, visual system employs a time-multiplexing approach in which each target alternates for prioritized access, a mechanism broadly known as rhythmic attentional sampling. For the past decade, rhythmic attentional sampling has received mounting support from converging behavioral and neural findings. However, so compelling are these findings that a critical test ground has been long overshadowed, namely the 3-D visual space where attention is complicated by extraction of the spatial layout of surfaces extending beyond 2-D planes.

In this study, we compared two experimental methods of selecting terms in expository text to generate reading representations and tested how well these reading representations predicted reading comprehension. The two experimental methods were the traditional method of using all terms (all keywords) to create participants' representation networks, and the terms categorization (TC) method of using only important terms (core and branch words). Representation networks were assessed using participants' adjacency scores, ratings of relatedness in pairs of terms, and using summary (summary writing) by all turms.

Time perception has been known to depend on the temporal frequency of the stimulus. Previously, the effect of temporal frequency modulation was assumed to be monotonically lengthening or shortening. However, this study shows that temporal frequency affects time perception in a non-monotonic and modality-dependent manner.

Photodynamic therapy (PDT), as a non-invasive and spatiotemporally controllable modality, exhibits great potential in cancer treatment. However, the efficiency of reactive oxygen species (ROS) production was restricted to the hydrophobic characteristics and aggregation-caused quenching (ACQ) of photosensitizers. Herein, we designed a ROS self-activatable nano system (denoted as PTKPa) based on poly(thioketal) conjugated with photosensitizers (PSs) pheophorbide A (Ppa) on the polymer side chains for suppressing ACQ and enhancing PDT.

Introduction: Parallel distributed processing theory (PDP theory) holds that all brain regions involved in conceptual representation perform a series of activities at the same time. However, the role of emotional experience information in concrete conceptual representation is still unknown. This study further explores whether the emotional experience will also affect the semantic processing of concrete concept representations.

Achievement emotions, defined as the emotions generated in the academic process or by achievement results, are critical for an individual's mental health, personality development, and academic productivity. Referring to the well-known big-fish-little-pond effect on academic self-concept, which describes the well-known phenomenon that students in selective schools/classes tend to have lower academic self-concepts than those who are comparably competent but attend regular schools/classes, Pekrun and colleagues focused on German students and proposed a similar happy-fish-little-pond effect on achievement emotions in 2019. In our paper, we examined whether this effect exists in extreme cases.
