Quantity discrimination in fish species: fish use non-numerical continuous quantity traits to select shoals

Fish typically prefer to live in big shoals due to the associated ecological benefits. Shoaling is a behavior that depends on the ability to quantitatively discriminate. The fundamental mechanism involved in quantity discrimination determines whether fish can discriminate a shoal using numerical discrete cues (e.g., number of shoal members), non-numerical continuous traits (e.g., total body surface area) or both; however, the mechanism is currently a controversial topic. In the present study, we used a spontaneous choice experiment to test whether guppy (Poecilia reticulata), zebrafish (Danio rerio), Chinese crucian carp (Carassius auratus) and qingbo (Spinibarbus sinensis) rely on continuous (i.e., body surface area) or discrete (i.e., number of shoal members) information for shoal selection by altering the body surface area (cumulative body surface area ratio of 3:2 or 1:1) between two stimulus shoals with a different number of members (2 individuals vs 3 individuals). All four fish species preferred to shoal with the stimulus shoal with the larger cumulative surface area even if the shoal had fewer members; however, fish showed no shoal preference when the cumulative surface body areas of both stimulus shoals were equal. Furthermore, qingbo did not numerically discriminate between a shoal with 1 individual and a shoal with 3 individuals when the cumulative surface areas of both stimulus shoals were equal; however, qingbo showed a preference for the shoal with the larger cumulative surface area when the two stimulus shoals each had 3 individuals. In conclusion, the present study demonstrated that all four fish species relied only on non-numerical continuous quantity information for shoal selection, at least under a difficult task (i.e., 2 vs 3).     

Gain or non‐loss: The message matching effect of regulatory focus on moral judgements of other‐orientation lies

Previous studies found that individuals with promotion focus are more likely to be persuaded by messages framed in terms of gain‐related words; individuals with prevention focus are more likely to be persuaded by messages framed in terms of loss‐related words. This is known as the message matching effect of regulatory focus. The present study extended this effect into the field of moral judgement of other‐orientation lies. Two experiments were conducted, revealing that (a) individuals with promotion focus judged gain‐framed other‐orientation lies to be more moral, while individuals with prevention focus judged non‐loss‐framed other‐orientation lies to be more moral; and (b) the subjective processing fluency had a partial mediating role in the message matching effect. Theoretical implications and future research directions were discussed.     

Online Module for Carrier Screening in Ashkenazi Jewish Individuals Compared with In-Person Genetics Education: A Randomized Controlled Trial

To increase accessibility to genetics services for low-urgency patients seeking Ashkenazi Jewish (AJ) carrier screening, we designed an interactive computer (IC) module that provides pre-test genetics education and allows genetics professionals to order the test without meeting the patients beforehand. We compared this module with in-person genetic counseling (GC) using a randomized trial. AJ individuals were randomized to undergo genetics education via the IC module (n = 26) or GC (n = 28). We compared post-interventional genetics knowledge, perceived genetic risk, and anxiety between the two groups, after accounting for pre-interventional scores, using ANCOVA. Wilcoxon Rank-Sum test was used to compare post-interventional satisfaction. Post-interventional genetics knowledge, risk perception, or anxiety were not significantly different between the two groups after accounting for baseline scores (p = 0.50–0.54), although the data are inconclusive regarding the module’s non-inferiority at a 5% margin. Post-intervention satisfaction scores were generally higher in the GC group than the IC module group. Our IC module has the potential to improve access to clinical genetics services for patients and staff, but it is not suitable for all AJ patients and cannot completely replace the benefits of in-person consultations.     

成就目标定向与小学生数学学习投入的关系:学业拖延和数学焦虑的中介作用

采用问卷法对708名小学高年级学生进行调查,以考察成就目标定向、学业拖延、数学焦虑与数学学习投入之间的关系,结果显示：（1）掌握定向和表现-接近定向均能直接正向预测数学学习投入,而表现-回避定向的直接预测作用不显著;（2）掌握定向、表现-接近定向和表现-回避定向均能通过学业拖延来间接预测数学学习投入;（3）掌握定向和表现-回避定向均能通过数学焦虑来间接预测数学学习投入,但表现-接近定向不能通过数学焦虑来间接预测数学学习投入;（4）三种成就目标定向均能通过学业拖延经数学焦虑的多重中介作用来预测数学学习投入。这表明成就目标定向不仅能直接预测,还能通过学业拖延和数学焦虑的多重中介作用,来间接预测小学生数学学习投入。     

父母体罚、学校参与与青少年网络游戏成瘾:亲子关系的调节作用

采用问卷法对1389名初中生进行调查,考察了学校参与在父母体罚与青少年网络游戏成瘾（Internet Gaming Addiction,IGA）关系间的中介效应,以及父子关系和母子关系在其中的调节效应。结果发现：（1）在控制了性别、年龄、家庭人均月收入和父母受教育水平后,父母体罚可显著正向预测青少年IGA;（2）学校参与显著部分中介父母体罚与青少年IGA的关系;（3）母子关系显著调节中介路径"父母体罚→学校参与→IGA",即父母体罚通过侵蚀青少年的学校参与进而增加其IGA的中介效应在高母子关系青少年群体中显著,但在低母子关系青少年群体中不显著。     

知觉与表象过程中不同线索表情的启动效应研究

探讨情绪性面孔的知觉和表象过程中,不同类型线索表情的启动效应,并关注不同类型表情表象难易的差异。选取NimStim数据库中20位演员的愉快、愤怒和中性表情作为启动刺激,随后呈现同一演员不同表情的图片,或通过颜色提示被试对不同表情进行表象,并同时进行表情类型判断。研究发现,情绪性面孔知觉与表象任务中均存在启动效应,之前呈现的线索面孔将会对接下来呈现的相同效价的面孔产生启动效应,对相反效价及中性面孔产生抑制; 在平衡不同类型面孔可能存在的启动效应后,正性、负性及中性表情是同样易于表象的。     

技艺与德性中的实践智慧——基于亚里士多德伦理学与当代伦理学自然主义的比较

亚里士多德在其古典伦理学中讨论了作为制作活动的技艺与作为实践活动的德性以及二者所依赖的实践智慧的联系与区别。基于亚里士多德的思想以及当代认知科学,这一类比研究延续到当代自然主义伦理学及其反思中。自然主义伦理学主张技艺与德性及其实践智慧之间存在着某种类同关系,源于亚里士多德德性伦理学的辩护者则主张技艺行为与德性行为的实践智慧在诸多方面存在区别。更进一步的研究表明,技艺行为和德性行为的实践智慧应当有效地整合,即技艺行为的实践智慧可能使人们对整体生活目标的反思更为正确,同时,技艺行为的实践智慧也同时应当遵从基于"好的人类生活"的更高规范标准。     

Filial piety dilemma solutions in Chinese adult children: The role of contextual theme,filial piety beliefs,and generation

Although some studies have revealed that traditional filial piety belief is weakening, few have explored whether and how the role of the belief in social life has changed correspondingly. The present study used questionnaires to examine solutions to filial piety dilemmas and the roles of contextual theme, filial piety beliefs, and generation in a sample of 123 young and 92 middle‐aged Chinese adults. With respect to the solutions adopted to solve parent?child conflicts, preferences varied depending on the dilemma themes. Specifically, participants were more likely to select a self‐sacrifice (rather than an ego‐centered) solution for respect dilemmas than for caring dilemmas, and least likely to do so for obedience dilemmas. Participants were also likely to select a balancing (rather than an ego‐centered) solution for respect or caring dilemmas than for obedience dilemmas. In addition, the concordance between beliefs and solutions was exhibited in reciprocal, but not authoritarian, filial piety beliefs. Individuals with stronger reciprocal filial piety beliefs were more likely to select self‐sacrifice or balancing solutions than ego‐centered solutions whereas authoritarian filial piety showed no influence on solutions for either young or middle‐aged adults. Furthermore, the generation effect was not significant, and the solution selection did not differ between young and middle‐aged adults.     

亲子支持与老年人抑郁情绪的关系:安全感和情绪表达的作用

采用问卷调查法,以362名老年人为研究对象,考察亲子支持与老年人抑郁情绪的关系,同时探讨安全感的中介作用以及情绪表达的调节作用。结果发现：（1）亲子支持显著负向预测老年人抑郁情绪;（2）安全感在亲子支持与老年人抑郁情绪的关系中起部分中介作用;（3）情绪表达调节亲子支持与老年人安全感的关系,相较于高情绪表达能力老年人,低情绪表达能力老年人的安全感更易受亲子支持的影响。本研究的发现表明,增强老年人的安全感以及情绪表达能力有助于减缓老年期抑郁情绪和维护老年人心理健康。     

论海德格尔对康德实践哲学的解读

海德格尔对康德实践哲学的解读是他阐释康德哲学的重要组成部分。本文围绕着道德情感、实践理性、实践自由等问题分析了海德格尔在这一方面的解读内容,并且指出海德格尔的解读是定向于存在论的,属于基础存在论筹划,人的存在问题是关注的核心。他力图发掘康德思想中的存在论-生存论的内涵,这反而丧失了原初的伦理学意义。
