The design of recommendation strategies in the adaptive learning systems focuses on utilizing currently available information to provide learners with individual-specific learning instructions. As a critical motivate for human behaviours, curiosity is essentially the drive to explore knowledge and seek information. In a psychologically inspired view, we propose a curiosity-driven recommendation policy within the reinforcement learning framework, allowing for an efficient and enjoyable personalized learning path. Specifically, a curiosity reward from a well-designed predictive model is generated to model one's familiarity with the knowledge space. Given such curiosity rewards, we apply the actor–critic method to approximate the policy directly through neural networks. Numerical analyses with a large continuous knowledge state space and concrete learning scenarios are provided to further demonstrate the efficiency of the proposed method. 相似文献

Reports linking prenatal testosterone exposure to autistic traits and to a masculinized face structure have motivated research investigating whether autism is associated with facial masculinization. This association has been reported with greater consistency for females than for males, in studies comparing groups with high and low levels of autistic traits. In the present study, we conducted two experiments to examine facial masculinity/femininity in 151 neurotypical adults selected for either low, mid-range, or high levels of autistic traits. In the first experiment, their three-dimensional facial photographs were subjectively rated by 41 raters for masculinity/femininity and were objectively analysed. In the second experiment, we generated 6-face composite images, which were rated by another 36 raters. Across both experiments, findings were consistent for ratings of photographs and composite images. For females, a linear relationship was observed where femininity ratings decreased as a function of higher levels of autistic traits. For males, we found a U-shaped function where males with mid-range levels of traits were rated lowest on masculinity. Objective facial analyses revealed that higher levels of autistic traits were associated with less feminine facial structures in females and less masculine structures in males. These results suggest sex-specific relationships between autistic traits and facial masculinity/femininity. 相似文献

Sleep problems are highly prevalent among school-attending youth, and impact on school performance and outcomes. Sleep-competing behaviours are likely factors in the inadequate sleep time and related functional outcomes observed in this population. We examined a range of sleep-competing behaviours and their associations with sleep variables in Australian school-attending youth. We also assessed whether these behaviours indirectly affected mental health and daytime functioning through poorer sleep quality. A total of 353 school-attending youth (mean age = 14.6 years, 53% female) were recruited from high schools in Australia, and completed a range of self-report measures. Approximately 50% of the youth obtained sub-optimal levels of sleep and reported having a problematically long sleep onset latency. Sleep competing behaviours, related and unrelated to electronic media use, were reported as occurring frequently, and were associated with a range of sleep variables. These behaviours were also related to poorer mental health and daytime sleepiness, with this association explained by indirect effects through sleep quality. Sleep-competing behaviours are prevalent on school nights in Australian youth, and may have adverse associations with mental health and functioning. Prevention and intervention programs might address the risk factors identified in the current study. 相似文献

Social anhedonia is associated with reduced social functioning and diminished reward from social interactions. Individuals expressing social anhedonia are likely to experience reduced social connectedness and feel lonely. Loneliness is also associated with reduced social functioning. Therefore, loneliness could account for the relationship between social anhedonia and social functioning. We aimed to determine whether loneliness mediates the relationship between social anhedonia and reduced social functioning. In total, 824 young adults (M age = 21.03, SD = 5.59; 72.3% female) completed the Revised‐Social Anhedonia Scale (RSAS), University of California Los Angeles (UCLA) Loneliness Scale, and the Social Functioning Scale (SFS). Scores on thee SFS were summed into six subscales: Social Withdrawal, Relationships, Social Activities, Recreational Activities, Independence (Competence), and Independence (Performance). Negative affect (Depression, Anxiety and Stress Scales‐21 [DASS] total score) was included as a covariate. Both the RSAS and the UCLA Loneliness Scale were negatively correlated with overall and all social functioning subscales. The DASS‐21 positively correlated with all variables of interest. Mediation analyses revealed that loneliness partially mediated the relationship between social anhedonia and the social functioning subscales, with the exception of Recreational Activities. However, loneliness was a full mediator for the relationship between social anhedonia and overall social functioning. The study findings suggest that targeting loneliness in interventions may be important for improving various aspects of social functioning in those individuals who express social anhedonia. 相似文献

It is an open question whether social stereotype activation can be distinguished from nonsocial semantic activation. To address this question, gender stereotype activation (GSA) and lexical semantic activation (LSA) were directly compared. EEGs were recorded in 20 participants as they identified the congruence between prime-target word pairs under four different conditions (stereotype congruent, stereotype incongruent, semantic congruent, and semantic incongruent). We found that congruent targets elicited faster and more accurate responses and reduced N400 amplitudes irrespective of priming category types. The N400 congruency effect (i.e., the difference between incongruity and congruity) started earlier and had greater amplitude for GSA than for LSA. Moreover, gender category priming induced a smaller N400 and a larger P600 than lexical category priming. These findings suggest that the brain is not only sensitive to both stereotype and semantic violation in the post-perceptual processing stage but can also differentiate these two information processes. Further, the findings suggest superior processing (i.e., faster and deeper processing) when the words are associated with social category and convey stereotype knowledge. 相似文献

This study provides a better understanding of using visual arts in counselling adults with depressive disorders. Three in-depth case studies were conducted in the counselling unit of a mental health hospital in Malaysia. Both qualitative and quantitative research methods were applied to explore three adult participants’ counselling experiences. They attended six individual counselling sessions, which included four art-making activities, and two after-session interviews, for approximately two months. Interpretative Phenomenological Analysis was used to analyse the qualitative data. The findings showed that through the therapeutic use of visual arts, the participants were able to explore and express various emotions, face their problems, communicate better with themselves and the counsellor, achieve a deeper self-understanding, and make meaningful progress in counselling, even though some of them experienced a sense of uncertainty at the beginning of some art-making activities. 相似文献

The velocities of motor and sensory conduction of median and ulnar nerves were measured on the left and right arms of 33 right-handed and 12 left-handed normal subjects. Contrary to current knowledge there was no statistically significant difference in the velocities of nerve conduction on the left and right sides of these subjects. It was suggested that the differences in the velocities of nerve conduction cannot contribute to the mechanisms of handedness. 相似文献

Chinese philosophy views experience as intrinsically aesthetic. This world view could be elucidated through a consideration of John Dewey's aesthetics and features of Chinese art. Dewey's philosophy of art starts with an understanding of experience as ‘live processes’ of living creatures interacting with their environment. Such processes are autopoietic in being self‐sustaining, ever‐changing, capable of increasing complexity, capable of generating novelty, direction and progress on its own. Its autopoietic character is a precondition of the aesthetic in the process of experience. An aesthetic experience is rhythmic, focused, consummatory, and reaches beyond the transitory boundaries of concrete existence. The aesthetic is not confined to what is conventionally identified as art. Most important, the ethical‐political, the natural and the cosmic all have an aesthetic aspect, as the paper attempts to show by examining classical Confucianism. 相似文献
