Collins’s incorrect depiction of Dreyfus’s critique of artificial intelligence

Harry Collins interprets Hubert Dreyfus’s philosophy of embodiment as a criticism of all possible forms of artificial intelligence. I argue that this characterization is inaccurate and predicated upon a misunderstanding of the relevance of phenomenology for empirical scientific research.

汉语中词长效应的初步实验研究

该文以回忆出一个词表的序列呈现顺序的正确率为指标考察汉语中的词长效应(Word-Length Effect)。实验材料为汉语中不同音节数目的词语。实验结果发现,在纯词表中,存在显著的词长效应。但是在混合词表中(包括长短词交替词表以及随机词表),词长效应会消失。研究结果支持词长效应的基于词表的解释,同时,项目的特异性也具有一定的作用。     

言语产生过程中语义、语音激活的ERP研究

使用ERP技术考察了言语产生过程中语音和语义的激活情况。图片上有3种条件的干扰词,分别与目标图片名称形成3种关系:语义相关,语音相同,语义、语音、字形都不相关。结果显示,当被试执行延迟命名任务(实验1)时,与目标图片名称语义相关和控制条件的波形比语音相关的波形更趋于负向。说明在图片命名过程中语音有明显的促进作用。当要求被试对上述图片进行延迟语义判断任务(实验2)时,与目标图片名称语义相关、语音相关及控制条件的波形之间无明显差异。说明在语义提取过程中没有语音的促进作用。综合实验1和实验2,本研究的结果更倾向于支持独立两阶段模型。     

Chatbot-Delivered Psychotherapy for Adults With Depressive and Anxiety Symptoms: A Systematic Review and Meta-Regression

Although psychotherapy is a well-established treatment for depression and anxiety, chatbot-delivered psychotherapy is an emerging field that has yet to be explored in depth. This review aims to (a) examine the effectiveness of chatbot-delivered psychotherapy in improving depressive symptoms among adults with depression or anxiety, and (b) evaluate the preferred features for the design of chatbot-delivered psychotherapy. Eight electronic databases were searched for relevant randomized controlled trials. Meta-analysis and random effects meta-regression was conducted using Comprehensive Meta-Analysis 3.0 software. Overall effect was measured using Hedges’s g and determined using z statistics at significance level p < .05. Assessment of heterogeneity was done using χ² and I² tests. A meta-analysis of 11 trials revealed that chatbot-delivered psychotherapy significantly improved depressive symptoms (g = 0.54, 95% confidence interval [−0.66, −0.42], p < .001). Although no significant subgroup differences were detected, results revealed larger effect sizes for samples of clinically diagnosed anxiety or depression, chatbots with an embodiment, a combination of types of input and output formats, less than 10 sessions, problem-solving therapy, off-line platforms, and in different regions of the United States than their counterparts. Meta-regression did not identify significant covariates that had an impact on depressive symptoms. Chatbot-delivered psychotherapy can be adopted in health care institutions as an alternative treatment for depression and anxiety. More high-quality trials are warranted to confirm the effectiveness of chatbot-delivered psychotherapy on depressive symptoms.PROSPERO registration number: CRD42020153332.     

Personal values and academic achievement

Using data from two studies, we investigate the role of basic values in predicting academic achievement. We focus on self-direction and conformity, two-value domains that have been neglected or understudied in earlier research on academic success. In line with the refined value theory, we split self-direction into independence of thought and of action, and conformity into compliance with rules and formal obligations (Rules), and avoidance of upsetting others (Interpersonal). We obtained grades as measures of academic achievement in two samples of Italian high-school students. In Study 1 (n = 234), we measured values with the PVQ-40 and academic motivation. In Study 2 (n = 215), we measured values with the PVQ-RR and both attendance rates and classroom conduct. Results: Both self-direction–thought and conformity–rules correlated with higher grades. These two values related to grades through a different path. Self-direction thought promoted grades through autonomous forms of academic motivation. Conformity rules promoted grades through better teachers’ evaluations of students’ classroom behaviour. Self-direction–action and conformity–interpersonal were unrelated to grades. Regarding the other values, hedonism and stimulation related negatively to grades. Theoretical and practical implications of results are discussed.     

The happy personality: Mediational role of trait emotional intelligence

This study examined the relationship between the Big Five personality traits (Gosling et al., 2003), trait emotional intelligence (EI) (Petrides & Furnham, 2001) and happiness (Argyle et al., 1989) in a sample of 112 (61 female) student and non-student participants. Strong dispositional determinants of happiness were identified. In line with previous findings, four of the Big Five, namely stability, extraversion, conscientiousness, and agreeableness, were positively correlated with both happiness and trait EI, which explained 18% of unique variance (over and above age and the Big Five) in happiness. Furthermore, a significant amount of shared variance between happiness and the Big Five was explained by trait EI, which partly mediated the paths from stability and conscientiousness to happiness, and fully mediated the link between agreeableness and happiness. Limitations and implications are discussed.     

Aging and strategic retrieval in a cued-recall test: the role of executive functions and fluid intelligence

Cued-recall in episodic memory was investigated in relation to low and high cognitive support at retrieval, executive function level and fluid intelligence level in 81 healthy adults divided first into two age groups (young and elderly adults). The first analyses showed that age-related differences were greater when a low cognitive support was provided to recall the words. An individual index of loss of performance when the number of cues was decreased was then calculated. Hierarchical regression analysis revealed that the executive functions measure (perseverative errors on the Wisconsin Card Sorting Test) was a better candidate than the fluid intelligence measure (Cattell's culture fair test) to account for the age-related variance of the size of performance loss. These findings suggest that age differences in implementing strategic retrieval may be mainly due to a decline in executive functions.     

一般流体智力的脑成像研究述评

对一般流体智力的脑成像研究有助于探明智力的脑机制。从结构成像与功能成像两个方面阐述了相关的研究。已有研究表明,一般流体智力与总的脑体积、额叶或其他多个脑区的灰质体积中等正相关。一般智力（g）因素负荷高的任务比负荷低的任务引发特定脑区更大的激活。较早的研究发现一般智力水平个体差异与脑区的激活呈负相关,但此后的一些研究却得到相反的结论。未来的研究应加强对个体差异的研究,将脑成像技术与EEG或ERP技术结合起来,整合多水平（心理测量、遗传学等）的研究结果,进一步阐明一般流体智力的脑机制     

文化智力研究评述与展望

文化智力是指人们与来自不同文化的其他人打交道时,采取有效措施以适应新文化的能力。文化智力的结构与测量,与其他相关构念的关系,以及不同的开发方法成了现有研究的重点;另外,也有实证研究表明,文化智力对一些结果变量有显著影响,例如认知结果、情感结果以及行为结果。本文对文化智力的相关研究进行了较为全面的总结,并指出了今后的研究趋势与方向     

社会智力研究视角和方法的转变——从社会智力的测量观到人格的社会智力观

在社会智力研究的早期,研究者们运用测量观的视角和方法对社会智力进行了研究,取得了不少的成果。但是随着研究的进行,传统测量观的发展却遇到了极大的困难,如不能对社会智力和学业智力进行有效的区分等。人格的社会智力观强调社会行为的背景具体化和行为的主观意义,主张探询人的一般化的社会认知机制,为社会智力的研究展开了一个新的视角。
