内隐学习潜在机制研究的某些新进展

内隐学习需要一定的注意和工作记忆参与,但关于它们影响内隐学习过程的潜在机制尚存在争议;随着内隐序列学习研究的深入,研究们开始关注序列知识的表征问题,这为揭示内隐知识的潜在表征机制开辟了新的途径;有关内隐学习神经机制的研究表明,基底神经节、联合区、额叶在内隐学习中起重要作用。     

股价和性别对模拟选股决策的影响

该模拟研究考察了股价和性别因素对股票新手选股决策的影响。股价为组内变量,分高低两个水平。被试是48名大学生,男女各半,均无股票操作经验。实验结果表明,股价对股票选择时间没有显著影响,但对被试体验到的冲突强度有明显影响,被试选择高价股时感受到的冲突强度显著高于选择低价股时感受到的冲突强度;在股票选择时间上存在显著的性别差异,女性选择时间明显长于男性的选择时间。     

Affective bias in visual working memory is associated with capacity

How does the affective nature of task stimuli modulate working memory (WM)? This study investigates whether WM maintains emotional information in a biased manner to meet the motivational principle of approaching positivity and avoiding negativity by retaining more approach-related positive content over avoidance-related negative content. This bias may exist regardless of individual differences in WM functionality, as indexed by WM capacity (overall bias hypothesis). Alternatively, this bias may be contingent on WM capacity (capacity-based hypothesis), in which a better WM system may be more likely to reveal an adaptive bias. In two experiments, participants performed change localisation tasks with emotional and non-emotional stimuli to estimate the number of items that they could retain for each of those stimuli. Although participants did not seem to remember one type of emotional content (e.g. happy faces) better than the other type of emotional content (e.g. sad faces), there was a significant correlation between WM capacity and affective bias. Specifically, participants with higher WM capacity for non-emotional stimuli (colours or line-drawing symbols) tended to maintain more happy faces over sad faces. These findings demonstrated the presence of a “built-in” affective bias in WM as a function of its systematic limitations, favouring the capacity-based hypothesis.     

Effortful semantic decision-making boosts memory performance in older adults

A major concern in age-related cognitive decline is episodic memory (EM). Previous studies indicate that both resource and binding deficits contribute to EM decline. Environmental support by task manipulations encouraging stronger cognitive effort and deeper levels of processing may facilitate compensation for these two deficits. To clarify factors that can counteract age-related EM decline, we assessed effects of cognitive effort (four levels) and level of processing (LoP, shallow/deep) during encoding on subsequent retrieval. Young (YAs, N?=?23) and older (OAs, N?=?23) adults performed two incidental encoding tasks, deep/semantic and shallow/perceptual. Cognitive effort was manipulated by varying decision-making demands. EM performance, indexed by d-prime, was later tested using a recognition task. Results showed that regardless of LoP, increased cognitive effort caused higher d-primes in both age groups. Compared to YAs, OAs showed a lower d-prime after shallow encoding across all cognitive effort levels, and after deep encoding with low cognitive effort. Deep encoding with higher levels of cognitive effort completely eliminated these age differences. Our findings support an environmental-compensatory account of cognitive ageing and can have important therapeutic implications.     

浅论《性命圭旨》中的性命观

"性命"是中国传统哲学的一对基本范畴,是儒、释、道、三家都关注的重要问题,但各家对其的理解和解释却不尽相同.<性命主旨>通过三教合通来阐释道教内丹学,融合中国传统文化中儒、释、道三家性命学的精髓,力倡性命双修,坚持性功、命功并重亦即精、气、神兼炼的原则,反对孤修一物.道教内丹是从后天的神气入手,其目的是修先天的元神、元气,最后神气合炼,提炼出元神.正是在这层意义上,该书尤其重视修心,并认为儒、释、道三家得以融合的核心就是"心性".     

Time course of effects of emotion on item memory and source memory for Chinese words

Although many studies have investigated the effect of emotion on memory, it is unclear whether the effect of emotion extends to all aspects of an event. In addition, it is poorly understood how effects of emotion on item memory and source memory change over time. This study examined the time course of effects of emotion on item memory and source memory. Participants learned intentionally a list of neutral, positive, and negative Chinese words, which were presented twice, and then took test of free recall, followed by recognition and source memory tests, at one of eight delayed points of time. The main findings are (within the time frame of 2 weeks): (1) Negative emotion enhances free recall, whereas there is only a trend that positive emotion enhances free recall. In addition, negative and positive emotions have different points of time at which their effects on free recall reach the greatest magnitude. (2) Negative emotion reduces recognition, whereas positive emotion has no effect on recognition. (3) Neither positive nor negative emotion has any effect on source memory. The above findings indicate that effect of emotion does not necessarily extend to all aspects of an event and that valence is a critical modulating factor in effect of emotion on item memory. Furthermore, emotion does not affect the time course of item memory and source memory, at least with a time frame of 2 weeks. This study has implications for establishing the theoretical model regarding the effect of emotion on memory.     

Motivating protégés' personal learning in teams: a multilevel investigation of autonomy support and autonomy orientation

This study examined the roles of 3 multilevel motivational predictors in protégés' personal learning in teams: an autonomy-supportive team climate, mentors' autonomy support, and protégés' autonomy orientation. The authors followed 305 protégés in 58 teams for 12 weeks and found that all 3 predictors were positively related to the protégés' personal learning in teams and that an autonomy-supportive team climate augmented the effects of mentors' autonomy support and protégés' autonomy orientation on protégés' personal learning in teams. Protégés' personal learning in teams mediated the interactive effects of an autonomy-supportive team climate with mentors' autonomy support or protégés' autonomy orientation on protégés' behavioral and attitudinal outcomes, including their organizational citizenship behaviors and job involvement. The findings of this study provide business researchers and practitioners with valuable insights into the management of autonomy.

道教在海南黎族地区的传播与民族化

黎族是我国唯一聚居在海南省内的少数民族,信仰以自然崇拜、祖先崇拜为主。汉元封元年(公元前110年),武帝在海南建郡立县,汉文化开始传入海南。由于长期汉、黎民族的历史交往与融汇,汉族本土宗教道教对黎族产生了历史性的影响。道教在黎族地区自唐、宋传入,经元、明两朝,至清代
