Abstract： A growing body of evidence suggested that time can be represented separately either on the lateral, sagittal or vertical axis. However, how these mental time lines originate and be activated remains controversial. Recent evidence supports that the lateral mental time line mainly originates from sensorimotor experience associated with reading/writing habits, and the activation may be a low-level sensorimotor mechanism. In contrast, the sagittal/vertical mental time line mainly originates from spatial metaphor in language, and the activation may be a high-level semantic mechanism. The future study should focus more on the diversity of origins, the gene basis, the neural mechanism and the analogy between mental time lines and mental number lines.

Abstract： The Gradedness of consciousness refers to whether conscious processing follows an “all-or-none” or “gradual” mode. The Richness of consciousness refers to whether conscious representations are “rich” or “sparse”. Our consciousness experience is explored from these two perspectives, i.e., the quality and the scope of processing, respectively. These two topics represent two important pathways toward decoding one of the basic scientific inquiries of mankind, i.e., Consciousness, in that any theory of consciousness formation must provide comprehensive, accurate, and reasonable explanations to them. In this review article, we first performed a thorough analysis of recent research progress for these two topics, aiming to clarify existing contradictions and ongoing debates between different explanatory views. Next, we indicated that these two research topics are intrinsically connected since each can be traced back to the long-standing disputations on whether cognitive access is necessary for the formation of consciousness. Finally, we carried out detailed analyses and discussions on how to advance the studies of the Gradedness and Richness of consciousness, and on how to provide an integrated interpretation to the complex performance of them under different experimental situations.

Abstract： Shared and private aesthetic tastes represent universal and idiosyncratic aesthetic processing, respectively. The new trending that combines both aesthetic tastes are challenging pre-existing “universal” aesthetic principles. Previous research focused mainly on whether aesthetic principles were statistically universal, neglecting the fact that aesthetic attributes can cause different reactions among individuals. This contradictory relationship between generality and particularity concerns one long-standing but essential topic in aesthetics: is beauty universal and objective or idiosyncratic and highly subjective? If an aesthetic principle is only based on the average aesthetic judgment and is able to ignore the differences of aesthetic experience among individuals, can such an aesthetic principle support the proposition that "beauty is universal"? This is a reflection on empirical aesthetics brought by research on aesthetic tastes. Therefore, if private taste does play a role in aesthetic tastes, then there's no doubt that future studies on empirical aesthetics will have to take into consideration both dependent variables: the average aesthetic reactions and the extent to which such aesthetic reactions differ among individuals. Recent studies on aesthetic tastes have revealed many factors that can modulate the relative weights between shared and private tastes, the most typical of which is stimulus domain. Studies have shown that the proportion of shared taste in artificial stimuli (such as architecture and art) is less than that in natural stimuli (such as faces and landscapes). Other studies further demonstrated that high-level object categories (e.g., faces vs landscapes) can override aesthetic principles based on low-level stimulus features (e.g., symmetry). Besides stimulus domain, other factors, including expertise, cultural backgrounds, previous experience and age, can affect the relative weights between shared and private tastes. Recent fMRI and EEG studies have explored the neural mechanisms of shared and private aesthetic tastes, the basis of which includes sensory pathways and the reward system. Similar sensory “impressions” among individuals triggered by the same aesthetic stimuli may be the prerequisite that aesthetic responses share some commonality among individuals. Meanwhile, the reward system, especially medial orbitofrontal cortex(mOFC), shows homologous activation patterns across different stimulus domains. Therefore, both sensory pathways and the reward system might be the neural basis of shared aesthetic taste. What’s more, studies found that default-mode network (DMN) are suppressed in a task requiring external focus, and are engaged in tasks requiring internally directed thought, such as autobiographical memory and autistic thinking. Given that DMN is typically activated in self-directed thinking, it is possible that DMN is more related to individual differences in aesthetic responses, and plays a more important role in private aesthetic tastes. Furthermore, take example for the PIA model and the VIMAP model, contemporary aesthetic processing models still owe an explanation for aesthetic tastes. And it is yet to clear how different aesthetic processing stages lead to changes in relative weights between shared and private tastes. Two completely opposite predictions and explanations can be reached by these models. The first one is that early stages in aesthetic models are driven more by stimuli, thus leading to more homogeneity in aesthetic responses and greater proportion of shared taste due to the objectivity of stimulus characteristics; in contrast, late aesthetic stages are driven more by perceivers, leading to more proportion of private taste. The other one also makes some sense: in stimulus-driven stages, the general “gist” formed by different perceivers can also be heterogeneous because at these stages individuals process the stimuli incompletely and insufficiently. However, in perceiver-driven stages, individuals process stimuli more intactly and sufficiently, thus it is possible that in these stages perceivers have more similar impressions of the targeted stimuli, resulting in higher proportions of shared taste. In the future, more relevant studies are required to expand stimulus domain of aesthetic evaluation and to explore the corresponding relationship between aesthetic tastes and different aesthetic processing stages.

Abstract： Serial dependence effect (SDE) refers to a stable and systematic attractive bias in which cognitive processing of the current stimuli is pulled toward the stimuli presented moments ago. Existing studies have revealed many factors modulating serial dependence effects. The first one is attention. Only stimuli that are consciously perceived can produce serial dependence effects. Secondly, sensory uncertainty of stimuli also affects serial dependence effects. Particularly, previous studies had found that stimuli with higher sensory uncertainty produced higher SDE intensity. The physical characteristics of stimuli also affect serial dependence effects. In addition, the spatial and temporal distances between the neighboring stimuli also have a tuning effect on serial dependence effects. All these distinctive features and special effects (caused perception bias, but did not influence reaction times) showed that the serial dependence effect is a brand new "history effect" (the influence of past stimuli on the current stimulus). The cognitive and neural mechanisms of serial dependence effects have received much attention. There are currently several mainstream views since 2014. The earliest view, i.e., the “continuity field” theory, believes that serial dependence is an effect purely at the perceptual level and occurs before the stage at which sensory signals are transformed into conscious representations. Some researchers also believe that serial dependence effects occur at the perceptual level and further they are modulated by neural feedback signals from higher levels. Another view attributes serial dependence effects to dynamic biases in working memory, while some researchers believe that serial dependence effects stem from decision-making processes. Finally, some researchers propose that serial dependence effects may exist at multiple cognitive processing stages and cannot be explained by a single mechanism. Recently, empirical progress had been made upon the neural mechanism of serial dependence effects. For example, Electroencephalogram (EEG) studies had revealed electrophysiological signals that can represent serial dependence effects starting from early stages of perceptual processing in adaptation paradigms. Evidence from fMRI studies also demonstrated an attractive bias at the level of early sensory representation imposed by previous perceptions. The latest research had discovered abnormal serial dependence effects in patients with brain injury. In addition, it was found that the dorsal premotor cortex had significant influence on visual movement-based serial dependence. The underlying mechanism of serial dependence effects is being uncovered gradually. Since been proposed, the serial dependence effect is thought to be a mechanism that promotes stability for visual processing by integrating visual input along the temporal dimension. However, some results are still controversial. Thus, there is still large space left for studies on serial dependence effects. In the future research, it is necessary to tackle the origin of serial dependence effects with multiple strategies, including innovation of experimental paradigms, data analysis approaches, and various cognitive neuroscience technologies. Further, future studies can focus on the modulating factors on serial dependence effects, and provide explanations to inconsistent results and individual differences of serial dependence effects in previous studies. Finally, it is also important to note that any psychological experimental design involving sequential visual stimuli in the future will have to consider the potential effects of serial dependence that may exist between past and current stimuli.

Abstract：
A novel “History effect”, i.e., the Serial Dependence Effect (SDE), was introduced into vision research since 2014. The SDE is an attractive bias in cognitive processing, referring to the phenomenon that the representation of a current stimulus is pulled toward the stimuli presented moments ago. Serial dependence has been observed in many substrates of visual processing, spanning from low-level features, such as orientation, spatial location, and numerosity, to high-level attributes, such as identity, attractiveness, and aesthetic judgment. Recent studies have revealed profound origins for this effect, including sensory coding, feedback regulation of high-level cortex, working memory, decision template, cascade of perception and decision, etc., which reflect projections of recent processing traces to current cognition from different levels. Abundant progress has been made on typical characteristics, modulating factors, cognitive and neural mechanisms, and theoretical explanations of the serial dependence effect. However, there are still many contradictions and ongoing debates that need to be explored and clarified by future researches.

Abstract： 近期研究发现时间可以分别在三个空间维度（左右、前后和上下）进行表征，但不同维度心理时间线的起源和激活机制尚存争议。最新证据表明，左右维度时间线主要起源于阅读/书写习惯所伴随的感觉运动经验，其激活可能是一种低水平的感觉运动机制；前后和上下维度时间线主要起源于语言中的空间隐喻，其激活可能是一种高水平的语义机制。未来研究应更关注心理时间线的起源多样性、先天基础、神经机制以及时间线和数字线的类比。
