Prefrontal cortex dysfunction and income: a study in neuroeconomics

In four samples of adults, individual income was negatively associated with a measure of prefrontal cortex dysfunction even after implementing controls for age, sex, and education. The small association was stronger for men than for women. These results provide support for a neuroeconomic approach to the study of micro-economic variables.     

Digital access and national character

A digital access index was associated with measures of national character (such as extraversion and individualism) for 18 industrialized nations, but statistical controls for gross domestic product per capita eliminated these associations.

Infants’ recognition of objects using canonical color

We explored infants’ ability to recognize the canonical colors of daily objects, including two color-specific objects (human face and fruit) and a non-color-specific object (flower), by using a preferential looking technique. A total of 58 infants between 5 and 8 months of age were tested with a stimulus composed of two color pictures of an object placed side by side: a correctly colored picture (e.g., red strawberry) and an inappropriately colored picture (e.g., green-blue strawberry). The results showed that, overall, the 6- to 8-month-olds showed preference for the correctly colored pictures for color-specific objects, whereas they did not show preference for the correctly colored pictures for the non-color-specific object. The 5-month-olds showed no significant preference for the correctly colored pictures for all object conditions. These findings imply that the recognition of canonical color for objects emerges at 6 months of age.     

Using State-Space Model with Regime Switching to Represent the Dynamics of Facial Electromyography (EMG) Data

Facial electromyography (EMG) is a useful physiological measure for detecting subtle affective changes in real time. A time series of EMG data contains bursts of electrical activity that increase in magnitude when the pertinent facial muscles are activated. Whereas previous methods for detecting EMG activation are often based on deterministic or externally imposed thresholds, we used regime-switching models to probabilistically classify each individual’s time series into latent “regimes” characterized by similar error variance and dynamic patterns. We also allowed the association between EMG signals and self-reported affect ratings to vary between regimes and found that the relationship between these two markers did in fact vary over time. The potential utility of using regime-switching models to detect activation patterns in EMG data and to summarize the temporal characteristics of EMG activities is discussed.     

On Luo Congyan’s Ethics

Luo Congyan put forward the idea that benevolence is the substance while righteousness is its function, which placed the intrinsic value of human beings on a more fundamental position and affirmed the unity of benevolent principle and universal norms from the perspective of the relationship between substance and function. The unity of benevolence and righteousness involves the connection between value and norms, and the latter relate to the relationship between morality and law in the broader sense. On the basis of the idea of using both benevolence and righteousness, Luo Congyan examined the relationship between morality and law. Corresponding to the emphasis on the role of both law and political power, Luo Congyan concerned himself with how to establish rational interpersonal relationships in various ways. Furthermore, Luo Congyan emphasized the significance of behavior in everyday life, while he affirmed that the universal principle should be followed. In this way, he developed the earlier Confucian thought. Translated from Studies in Ethics by Xiao Mo     

《大学生主观幸福感量表》的编制

根据国内外关于主观幸福感的文献和已有的研究经验,编制了大学生主观幸福感问卷。以往大多数研究认为,主观幸福感由生活满意度和情绪体验两个基本成分构成,本研究认为主观幸福感还应包括社会性行为和人际关系等成分。对376名大学生进行初测,通过探索性因素分析,表明大学生主观幸福感由自我满意、家庭满意、消极情绪、积极情绪、精力、生活满意、社会性行为和人际关系8个维度构成,共41个项目。对511名大学生施测41个项目的主观幸福感问卷,进行验证性因素分析,结果表明,上述结构是合理的。     

The effect of emotion-focused orientation at retrieval on emotional memory in young and older adults

This study examines how emotion-focused orientation at retrieval affects memory for emotional versus neutral images in young and older adults. A total of 44 older adults (ages 61–84 years, M=70.00, SD=5.54) and 43 young adults (ages 17–33 years, M=20.58, SD=3.72) were tested on their free recall and forced-choice recognition of images. At retrieval the emotion-focused orientation was manipulated by instructing participants to focus on emotion-related information (i.e., emotional content of images and the emotional reactions evoked by the images). In the control conditions participants were either instructed to focus on visual information or not provided any specific orientation instruction. In free recall but not forced-choice recognition, the emotion-focused orientation increased young adults’ positivity bias and thus wiped out their superior negativity bias. However, the emotion-focused orientation did not affect older adults’ emotional memory. The data suggest that young adults activate and prioritise emotional goals in response to external demand during intentional information processing whereas older adults seem to spontaneously tune themselves to emotional goals.
