文化与人格研究中的几个问题

“文化与人格”包含着“文化中的人格”和“人格中的文化”两个命题。当今人格与文化研究中存在几个问题:人格特质的跨文化普遍性问题;人格与文化研究中的文化问题;人格与文化的作用机制问题。要解决这些问题:1.将主位研究与客位研究结合起来;2.将文化看作动态的过程;3.考虑到文化与人格之间起作用的中间机制;4.加强人格心理学与其它学科的联系。     

Dissociation and association of the embodied representation of tool-use verbs and hand verbs: An fMRI study

Embodied semantic theories suppose that representation of word meaning and actual sensory-motor processing are implemented in overlapping systems. According to this view, association and dissociation of different word meaning should correspond to dissociation and association of the described sensory-motor processing. Previous studies demonstrate that although tool-use actions and hand actions have overlapping neural substrates, tool-use actions show greater activations in frontal–parietal–temporal regions that are responsible for motor control and tool knowledge processing. In the present study, we examined the association and the dissociation of the semantic representation of tool-use verbs and hand action verbs. Chinese verbs describing tool-use or hand actions without tools were included, and a passive reading task was employed. All verb conditions showed common activations in areas of left middle frontal gyrus, left inferior frontal gyrus (BA 44/45) and left inferior parietal lobule relative to rest, and all conditions showed significant effects in premotor areas within the mask of hand motion effects. Contrasts between tool-use verbs and hand verbs demonstrated that tool verbs elicited stronger activity in left superior parietal lobule, left middle frontal gyrus and left posterior middle temporal gyrus. Additionally, psychophysiological interaction analyses demonstrated that tool verbs indicated greater connectivity among these regions. These results suggest that the brain regions involved in tool-use action processing also play more important roles in tool-use verb processing and that similar systems may be responsible for word meaning representation and actual sensory-motor processing.     

错误记忆研究范式评介

文章概括评介了当前错误记忆研究的几种主要范式及其各自可能的认知机制。联想研究范式(包括集中联想研究范式与类别联想研究范式)和无意识知觉范式描述了人们对单词的错误记忆,而误导信息干扰范式和KK研究范式则描述了人们对持续事件的错误记忆。这两类不同的研究范式证实了可能存在不同类型的错误记忆,且可能具有不同的认知加工机制。它们都从一定层面上揭示了错误记忆现象的本质和特征,并为人们进行更深入的研究提供了有效的方法。     

Decreased parahippocampal activity in associative priming: evidence from an event-related fMRI study

In recent years, there has been intense debate on the neural basis of associative priming, particularly on the role of the medial temporal lobe (MTL) in retrieving associative information without awareness. In this study, event-related fMRI was used while healthy subjects performed a perceptual identification task on briefly presented unrelated word pairs and an associative recognition memory task. Contamination of priming by explicit memory was successfully controlled, as associative priming and explicit memory were dissociated on the behavioral level. The fMRI results showed a functional dissociation within the MTL with respect to associative priming effects. The right parahippocampal cortex, but not the hippocampus, showed decreased activation for old vs. new pairs and old vs. recombined pairs (associative priming). The bilateral hippocampus and the right parahippocampal cortex were involved in explicit associative memory. These data provide evidence that subregions of the MTL participate in associative priming even when explicit involvement was controlled. Thus, different regions within the MTL play distinct roles in explicit and implicit associative memory.     

探寻理论化的德性伦理思想的复兴之路

20世纪五六十年代之后,西方德性伦理的复兴成为当代伦理学发展的前沿领域。在德性伦理思想的复兴中,主张理论化的德性伦理思想与早期反理论化的伦理思想有着重要的区别。努斯鲍姆、斯洛特、赫斯特豪斯等人认为,自近代以来,德性的失落与现代道德哲学中理性没有真正地充分发挥其本来作用有关。他们就此批判功利主义,力主伦理理论化的思想,开创了理论化的德性伦理思想的复兴之路。     

Ethical Academic Judgments and Behaviors: Applying a Multidimensional Ethics Scale to Measure the Ethical Academic Behavior of Graduate Students

Using Reidenbach and Robin's Multidimensional Ethics Scale, this study investigated the relationships between background variables and students' ethical evaluations, judgments, and behavioral intentions using 3 scenarios involving dilemmas related to academic dishonesty. The sample included 436 master's students and 142 doctoral students. The study found that the participants used a combination of ethical philosophies to make ethical decisions. The respondents judged improper citations more harshly than acts of inappropriate authorship or the falsification of data. The doctoral students generally considered behaviors related to plagiarism and falsification to be more unethical than the master's students did, though no gender differences were found.

Bias in longitudinal data analysis with missing data using typical linear mixed‐effects modelling and pattern‐mixture approach: An analytical illustration

We analytically derive the fixed‐effects estimates in unconditional linear growth curve models by typical linear mixed‐effects modelling (TLME) and by a pattern‐mixture (PM) approach with random‐slope‐dependent two‐missing‐pattern missing not at random (MNAR) longitudinal data. Results showed that when the missingness mechanism is random‐slope‐dependent MNAR, TLME estimates of both the mean intercept and mean slope are biased because of incorrect weights used in the estimation. More specifically, the estimate of the mean slope is biased towards the mean slope for completers, whereas the estimate of the mean intercept is biased towards the opposite direction as compared to the estimate of the mean slope. We also discuss why the PM approach can provide unbiased fixed‐effects estimates for random‐coefficients‐dependent MNAR data but does not work well for missing at random or outcome‐dependent MNAR data. A small simulation study was conducted to illustrate the results and to compare results from TLME and PM. Results from an empirical data analysis showed that the conceptual finding can be generalized to other real conditions even when some assumptions for the analytical derivation cannot be met. Implications from the analytical and empirical results were discussed and sensitivity analysis was suggested for longitudinal data analysis with missing data.
