Identifying strongly with a salient future self increases future-oriented behaviour. Self-report measures can detect variations in future self-identification within and between individuals on the dimensions of vividness, similarity, and positivity. We adapted the Self Association Task (SAT) to detect preconscious perceptual processing biases towards future self-related information. Participants were instructed to imagine different versions of their future selves, constructed using one of the three dimensions mentioned above. These imaginations were followed by the implicit SAT and explicit self-report measures of future self-identification. The similar and positive future self-imaginations led to increased subjective future self-identification. While a classic self-prioritisation effect was prominent throughout, similarity constructs of the future self also elicited processing biases on accuracy but not response time. As suggested by philosophical theories on self-continuity, the construct of a future self can influence future self-identification and direct future-oriented cognitions and behaviours.

The self, like the concept of central "gravity", facilitates the processing of information that is directly relevant to the self. This phenomenon is known as the self-prioritization effect. However, it remains unclear whether the self-prioritization effect extends to the processing of emotional facial expressions. To fill this gap, we used a self-association paradigm to investigate the impact of self-relevance on the recognition of emotional facial expressions while controlling for confounding factors such as familiarity and overlearning. Using a large and diverse sample, we replicated the effect of self-relevance on face processing but found no evidence for a modulation of self-relevance on facial emotion recognition. We propose two potential theoretical explanations to account for these findings and emphasize that further research with different experimental designs and a multitasks measurement approach is needed to understand this mechanism fully. Overall, our study contributes to the literature on the parallel cognitive processing of self-relevance and facial emotion recognition, with implications for both social and cognitive psychology.

Photothermoelectric (PTE) detectors combine photothermal and thermoelectric conversion, surmounting material band gap restrictions and limitations related to matching light wavelengths, have been widely used in telecommunication band detection. Two‐dimensional (2D) materials with gate‐tunable Seebeck coefficient can induce the generation of photothermal currents under illumination by the asymmetric Seebeck coefficient, making them promising candidate for PTE detectors in the telecommunication band. In this work, we report that a newly explored van der Waals (vdW) layered material, SnP2Se6, possessing excellent field regulation capabilities and behaviors as an ideal candidate for PTE detector implementation. With the assistance of temperature‐dependent Raman characterization, the suspended atomic thin SnP2Se6 nanosheets reveal thickness‐dependent thermal conductivity of 1.4–5.7 W m−1 K−1 at room temperature. The 2D SnP2Se6 demonstrates high Seebeck coefficient (S) and power factor (PF), which are estimated to be −506 μV K−1 and 207 μW m−1 K−2, respectively. By effectively modulating the SnP2Se6 localized carrier concentration, which in turn leads to inhomogeneous Seebeck coefficients, the designed dual‐gate PTE detector with 2D SnP2Se6 channel demonstrates wide spectral photoresponse in telecommunication bands, yielding high responsivity (R = 1.2 mA W−1) and detectivity (D* = 6 × 109 Jones) under 1550 nm light illumination. Our findings provide a new material platform and device configuration for the telecommunication band detection. [ABSTRACT FROM AUTHOR]

With the increasing popularity of social media represented by Weibo,rumors spread rapidly through social media,which is more likely to cause serious consequences.The problem of automatic rumor detection has attracted widespread attention from academic and industrial circles at home and abroad.We have noticed that more and more users use pictures to post Weibo,not just text.Weibo usually consists of text,images and social context.Therefore,a multi-modal network rumor detection method DCNN based on deep neural network for the text content,image and user attribute information of the accompanying text is proposed.This method consists of a multi-modal feature extractor and a rumor detector.The multi-modal feature extractor is divided into three parts:a text feature extractor based on TextCNN,a picture feature extractor based on VGG-19,and a user social feature extractor based on DeepFM algorithm.These three parts learn feature representations on different modalities of Weibo to form re-parameterized multi-modal features,which are fused as input to the rumor detector classification detection.This algorithm has carried out a large number of experiments on the Weibo data set,and the experimental results show that the recognition accuracy of DCNN algorithm is improved from 78.1% to 80.3%,which verifies the feasibility and effectiveness of DCNN algorithm and feature interaction method for social characteristics.

Examining the pollination biology of plant species is not only crucial for enhancing our understanding of their reproductive biology, but also essential for elucidating their adaptation and evolutionary history. Here, we investigated the breeding system and pollination biology of two closely related species in Actaea. The flower of A. purpurea is unique in the genus with purple and chartaceous (paper-like) sepals, fewer stamens with yellow anthers and purple filaments. Through three seasons of field observation and exclusion experiments, we determined that A. purpurea was primarily pollinated by a hornet species, Vespa bicolor , which also served as the most efficient pollinator. In contrast, A. japonica was primarily pollinated by large flies. Actaea purpurea exhibited a significantly higher cumulative nectar volume than A. japonica , which could be a crucial factor in attracting V. bicolor. A control experiment further demonstrated that removing the nectar leaf (petal) significantly decreased the visiting frequency of V. bicolor. Breeding system studies revealed that both species were self-compatible, yet they primarily underwent outcrossing in natural habitats. Our study presents a compelling case of possible pollinator shift in A. purpurea accompanied by morphological divergence. A more in-depth investigation of this system would offer crucial insights into the extent to which pollinators are involved in the plant speciation process and whether they contribute to reproductive isolation between closely related species.

Background: Humans perceive and interpret the world through the lens of self-reference processes, typically facilitating enhanced performance for the task at hand. However, this research has predominantly emphasized the automatic facet of self-reference processing, overlooking how it interacts with control processes affecting everyday situations. Methods: We investigated this relationship between automatic and control self-reference processing in neuropsychological patients performing self-face perception tasks and the Birmingham frontal task measuring executive functions. Results: Principal component analysis across tasks revealed two components: one loaded on familiarity/orientation judgments reflecting automatic self-reference processing, and the other linked to the cross task and executive function indicating control processing requirements. Voxel-based morphometry and track-wise lesion-mapping analyses showed that impairments in automatic self-reference were associated with reduced grey matter in the ventromedial prefrontal cortex and right inferior temporal gyrus, and white matter damage in the right inferior fronto-occipital fasciculus. Deficits in executive control were linked to reduced grey matter in the bilateral inferior parietal lobule and left anterior insula, and white matter disconnections in the left superior longitudinal fasciculus and arcuate fasciculus. Conclusions: The causal evidence suggests that automatic and control facets of self-reference processes are subserved by distinct yet integrated ventral prefrontal–temporal and dorsal frontal–parietal networks, respectively.

Using electroencephalogram (EEG), we tested the hypothesis that the association of a neutral stimulus with the self would elicit ultra-fast neural responses from early top-down feedback modulation to late feedforward periods for cognitive processing, resulting in self-prioritization in information processing. In two experiments, participants first learned three associations between personal labels (self, friend, stranger) and geometric shapes (Experiment 1) and three colors (Experiment 2), and then they judged whether the shape/color–label pairings matched. Stimuli in Experiment 2 were shown in a social communicative setting with two avatars facing each other, one aligned with the participant's view (first-person perspective) and the other with a third-person perspective. The color was present on the t-shirt of one avatar. This setup allowed for an examination of how social contexts (i.e., perspective taking) affect neural connectivity mediating self-related processing. Functional connectivity analyses in the alpha band (8–12 Hz) revealed that self–other discrimination was mediated by two distinct phases of neural couplings between frontal and occipital regions, involving an early phase of top-down feedback modulation from frontal to occipital areas followed by a later phase of feedforward signaling from occipital to frontal regions. Moreover, while social communicative settings influenced the later feedforward connectivity phase, they did not alter the early feedback coupling. The results indicate that regardless of stimulus type and social context, the early phase of neural connectivity represents an enhanced state of awareness towards self-related stimuli, whereas the later phase of neural connectivity may be associated with cognitive processing of socially meaningful stimuli.

Aim: To understand why some parents are less sensitive to infant cues than others, we need to understand how healthy parents respond, and how this is influenced by factors such as sleep deprivation. Here, we examined whether sleep deprivation alters the self‐infant‐prioritisation effect in a population of first‐time mothers within their first year of motherhood. Methods: The study took place at Aarhus University Hospital in Denmark from August 2018 until February 2020. First‐time mothers were recruited through Midwife clinics, national and social media. All women completed a perceptual matching task including an infant category. The mothers were divided into two groups depending on their sleep status: below or above 7 h of average night‐time sleep, measured with actigraphy. Results: Forty‐eight first‐time mothers at the age of 29.13 ± 3.87 years were included. In the sleep‐deprived group, the infant category was statistically significantly higher in accuracy (p = 0.005) and faster in reaction time (p < 0.001) than all other categories. In contrast, in the non‐sleep‐deprived group, there was no statistically significant difference between self and infant, neither in accuracy, nor reaction time. Conclusion: Sleep‐deprived new mothers strongly prioritised infants over self, while non‐sleep‐deprived new mothers showed no prioritisation of the self over the infant. [ABSTRACT FROM AUTHOR]

Aim: This study used a screen‐based perceptual matching task to see how non‐parents, people trying to get pregnant, and those who had given birth prioritised shapes and labels relating to self or infant conditions. Methods: The study took place at Aarhus University Hospital in Denmark from December 2016 to November 2021. Recruitment methods included family planning clinics, social media, online recruitment systems and local bulletin boards. The modified perceptual matching task linked five shapes to five labels, including self and infant. Results: We found that 67 males and females with a mean age of 24.4 ± 3 years, who had no plans to become parents in the near future, reacted faster and more accurately to self‐shapes and labels (p < 0.001), which validated the experiment. The 56 participants aged 27.1 ± 4.4 years who were actively trying to become parents showed no statistically significant prioritisation. A subset of 21 participants aged 28.7 ± 4.4 years showed faster response times to infant than self‐shapes and labels 1 year after giving birth (p < 0.001). Conclusion: Healthy first‐time parents showed faster reactions to infant than self‐conditions 1 year after giving birth, in contrast to the other two groups. [ABSTRACT FROM AUTHOR]
