Pediatric Predispositional Genetic Risk Communication: Potential Utility for Prevention and Control of Melanoma Risk as an Exemplar

Predispositional genetic testing among minor children is intensely debated due to the potential benefits and harms of providing this type of genetic information to children and their families. Existing guidelines on pediatric genetic testing state that predispositional testing could be appropriate for minors if preventive services exist that mitigate children’s risk for or severity of the health condition in question. We use the example of hereditary melanoma to illustrate the rationale for and potential application of genetic risk communication for an adult-onset cancer to a pediatric population where childhood behaviors may reduce risk of disease later in life. We draw from the adult melanoma genetic risk communication and pediatric health behavior change literatures to suggest ways in which genetic test reporting and complementary education could be delivered to children who carry a hereditary risk for melanoma and their families in order to foster children’s engagement in melanoma preventive behaviors. Genetic discoveries will continue to yield new opportunities to provide predispositional genetic risk information to unaffected individuals, including children, and could be delivered within programs that provide personalized and translational approaches to cancer prevention.     

Teaching children with autism to follow gaze shift: A brief report on three cases

This study evaluated the extent to which prompting and reinforcement increased three participants' correct selections of items following a therapist's gaze shift using a non‐concurrent multiple baseline design for two participants and an ABCD design for one participant. Results show that each participant learned to discriminate an adult's gaze direction to make a correct selection and each participant's responding generalized to selections with non‐reinforcing stimuli. Two participants also displayed the skill during probe sessions with their parents; however, the third participant required tangible reinforcement for correct selections to demonstrate the skill with a parent.     

Validation of the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Chinese adolescents

We sought to validate the Dutch Eating Behavior Questionnaire (DEBQ) in a sample of Chinese adolescents and investigate differences in eating behaviors among Chinese normal weight, overweight, and obese adolescents. Chinese middle and high school students completed the DEBQ, Eating Disorder Inventory-1, and the Self-Control Scale. Result showed that the DEBQ had good internal consistency, test–retest reliability and criterion validity. Furthermore, the obese and overweight adolescents scored significantly higher than normal weight adolescents on three subscales. The DEBQ is effective for assessing eating behaviors in Chinese adolescents.     

Norms of valence,arousal, concreteness,familiarity, imageability,and context availability for 1,100 Chinese words

In the present study, we collected valence, arousal, concreteness, familiarity, imageability, and context availability ratings for a total of 1,100 Chinese words. The ratings for all variables were collected with 9-point Likert scales. We tested the reliability of the present database by comparing it to the extant Chinese Affective Word System, and performed split-half correlations for all six variables. We then evaluated the relationships between all variables. Regarding the affective variables, we found a typical quadratic relation between valence and arousal, in line with previous findings. Likewise, significant correlations were found between the semantic variables. Importantly, we explored the relationships between ratings for the affective variables (i.e., valence and arousal) and concreteness ratings, suggesting that valence and arousal ratings can predict concreteness ratings. This database of affective norms will be a valuable source of information for emotion research that makes use of Chinese words, and will enable researchers to use highly controlled Chinese verbal stimuli to more reliably investigate the relation between cognition and emotion.     

自然关联性:概念、测量、功能及干预

自然关联性是指人们主观上感到与自然融为一体的程度,包括对自然的认知、情感和行为三个维度。自然关联性的测量主要采用自陈式量表和内隐联系测验从外显和内隐两个层面进行。已有理论与实证研究发现,与自然接触能够帮助恢复心理疲劳、改善认知表现、缓解身心症状、提升幸福感、促进亲社会行为。研究者采用了多种干预方式提升自然关联性。未来的研究需要进一步探究自然关联性的概念、研究方法、积极效应的条件、以及文化的影响等。     

语法性别对认知的影响及其机制

语法性是许多语言中普遍存在的现象。它本质上属于句法属性,但是一定程度上关联着语义,而且会影响个体对物体的分类、知觉、认知加工,以及对二语的学习等认知活动,其对认知的影响程度受任务、语言、语法性透明度等因素调节。语法性影响认知的机制主要有概念水平上的相似性假设;生物性假设;词汇水平上的双选择模型。未来的研究要进一步探究语法性的认知机制、二语学习中语法性习得的认知过程、语法性不同形式性别差异影响的机制。     

汉字部件水平的重复知盲效应

本研究采用不同部件特点的汉字材料考察在汉字部件水平的重复知盲效应。实验1探究在一组刺激序列中,当两个关键刺激R1和R2的相同部件在不同位置时对重复知盲效应的影响。实验1结果表明,不同条件的重复知盲效应存在显著差异,但其中两个关键字中相同部件的位置相同时与部件位置不同时之间的重复知盲效应无显著差异,这表明部件位置对重复知盲现象无显著影响。实验2探究当关键刺激R1和R2为部件包含关系时的重复知盲效应。实验2结果表明,当一个关键刺激为独体字,且是另一个关键刺激的部件时存在重复知盲效应,其效应的大小会受到具有包含关系的两个关键字（合体字和独体字）在刺激序列中出现顺序的影响,当第二个关键刺激为独体字时的重复知盲效应要显著强于第二个关键刺激为合体字条件。研究结论是不同的汉字部件特点会影响重复之盲效应,这表明重复知盲现象很可能发生在在线的知觉加工过程。     

美术专业与普通专业学生对中西方绘画作品的审美认知差异

审美认知是人类最高级最复杂的心理活动之一,在美育中具有重要的作用。本研究采用不同艺术类别及情绪效价的作品图片,考察美术专业与普通专业大学生对中西方绘画作品的审美认知差异。结果发现：美术专业学生与普通学生对西方画的审美认知差异极其显著,且美术专业学生对西方画产生的美感显著强于普通学生;而两类学生对中国画的审美认知差异并不显著;对于不同风格的绘画作品,两类学生都存在着审美偏好,且审美偏好一致,都对中国画产生的美感更为强烈;两类学生的审美认知反应时间差异极其显著,专业学生总体上要比普通学生进行更多更复杂的审美认知加工活动。研究表明,审美认知具有较强的可塑性,对于美育心理学的发展具有重要的价值。

追求积极情绪可能导致消极后果及其机制探讨

近年来有关研究发现了追求积极情绪可能给个体带来消极后果, 即个体越追求积极情绪, 他们很可能越体验不到幸福, 并称之为“追求积极情绪的悖论”。当个体把追求积极情绪作为目标时, 可能会(1)为个人的快乐设定过高的标准; (2)通过不恰当的活动去获得快乐; (3)监控获得快乐的过程, 妨碍了沉浸体验。这三个心理过程导致了“追求积极情绪的悖论”。未来的研究应该进一步关注：(1)全面揭示追求积极情绪的后果; (2)揭示追求积极情绪导致消极后果的生理神经机制; (3)追求积极情绪的跨文化研究; (4)探索正确追求积极情绪的方式。
