Dopamine D1 receptors are responsible for stress-induced emotional memory deficit in mice

It is established that stress impairs spatial learning and memory via the hypothalamus-pituitary-adrenal axis response. Dopamine D1 receptors were also shown to be responsible for a stress-induced deficit of working memory. However, whether stress affects the subsequent emotional learning and memory is not elucidated yet. Here, we employed the well-established one-trial step-through task to study the effect of an acute psychological stress (induced by tail hanging for 5, 10, or 20?min) on emotional learning and memory, and the possible mechanisms as well. We demonstrated that tail hanging induced an obvious stress response. Either an acute tail-hanging stress or a single dose of intraperitoneally injected dopamine D1 receptor antagonist (SCH23390) significantly decreased the step-through latency in the one-trial step-through task. However, SCH23390 prevented the acute tail-hanging stress-induced decrease in the step-through latency. In addition, the effects of tail-hanging stress and/or SCH23390 on the changes in step-through latency were not through non-memory factors such as nociceptive perception and motor function. Our data indicate that the hyperactivation of dopamine D1 receptors mediated the stress-induced deficit of emotional learning and memory. This study may have clinical significance given that psychological stress is considered to play a role in susceptibility to some mental diseases such as depression and post-traumatic stress disorder.     

Non-target language processing in Chinese-English bilinguals: a study of event-related potential

The event-related brain potential (ERP) technique was used to investigate the neural mechanism of non-target language processing in Chinese-English bilinguals. Participants were presented with a mixed list of Chinese and English words and required to make conceptual decisions for words in one language and ignore words in the other non-target language. Regardless of whether the nontarget word was in Chinese or English, the ERPs they elicited were modulated by word frequency, suggesting that their meaning had been accessed. The N400 peak was delayed in the English as the non-target language condition, probably because participants were less proficient in English. The results suggest that the non-target language can be processed during conceptual tasks with participants' proficiency in this language being a critical factor.     

Exploratory and confirmatory factor analysis of a short-form of the EMBU among Chinese adolescents

The present study used a sample of Chinese adolescents and validated a short-form of the Egna Minnen Betr?ffande Uppfostran: One's Memories of Upbringing (s-EMBU) assessing perceived parental rearing styles. A Chinese revision of the s-EMBU by the authors was administered to a total of 779 high school students, ages 11 to 19 years. Exploratory factor analysis with half of the sample yielded a three-factor solution of Rejection, Emotional Warmth, and Overprotection, accounting for 47.1% of the total variance onthe father form and 48.8% of the total variance on the mother form. Then, confirmatory factor analysis indicated a good fit of the three-factor model to the data in the other half of the sample. The three subscales consisted of 6, 6, and 7 items, respectively. Scores on these subscales had Cronbach alphas ranging from .71 to .81, indicating adequate internal consistency. These psychometric properties suggest its applicability for research with Chinese adolescents.     

Neural correlates of audiovisual integration of semantic category information

Previous studies have found a late frontal-central audiovisual interaction during the time period about 150-220 ms post-stimulus. However, it is unclear to which process is this audiovisual interaction related: to processing of acoustical features or to classification of stimuli? To investigate this question, event-related potentials were recorded during a words-categorization task with stimuli presented in the auditory-visual modality. In the experiment, congruency of the visual and auditory stimuli was manipulated. Results showed that within the window of about 180-210 ms post-stimulus more positive values were elicited by category-congruent audiovisual stimuli than category-incongruent audiovisual stimuli. This indicates that the late frontal-central audiovisual interaction is related to audiovisual integration of semantic category information.     

Gender Differences in Covert Fidelity Management among Dating Individuals in China

This study examined gender differences in covert fidelity management among dating individuals in China. Fidelity management refers to tactics and behaviors people use to monitor their partners’ fidelity. Two hundred and thirty two young adults (18–26?years old, M?=?23.44, SD?=?1.93) primarily from the cities of Beijing, Wuhan, Dalian, and Guangzhou in mainland China completed a questionnaire designed to measure self-esteem, trust, peer influence, relationship satisfaction and covert fidelity management. Consistent with our hypothesis, women were found to engage in more covert fidelity management than men. Regression results revealed that for both women and men, trust and peer influence were significant predictors of covert fidelity management behavior. However, self-esteem was a significant predictor of men’s covert fidelity management, not women’s. Furthermore, covert fidelity management was found not related to women’s relationship satisfaction, but was significantly associated with men’s satisfaction in a negative direction. These findings have interesting implications for understanding romantic partners’ behaviors in infidelity-related situations.     

Age-related and situation-related social desirability responding among Chinese teachers

Social desirability responding (SDR) was affected by situation and age. However, most research is only concerned with overall SDR without considering the separation of impression management and self-deception. The purpose of this article is to explore the possible different effects of age and situation on the different components of SDR. A total of 158 teachers completed the BIDR at a 2 (high vs. low SDR situation) x 2 (20-29 vs. 30-39 years old) between-group experiment. The results of multivariate analyses, with gender and tenure controlled, suggested that the effects of age and situation on the four specific components were mixed. Impression management enhancement (IME) and denial (IMD) were significantly affected by situations. The older group had significantly higher self-deception enhancement (SDE) and IME scores than the younger one. Females had significantly higher IME scores than males. More age stages and the main effect of gender should be considered in the future.     

Role of self-esteem in the relationship between stress and ingratiation

The relations among self-esteem, stress, and ingratiatory behaviors in the workplace were examined. Competing models for moderating and mediating effects of self-esteem on the relationship between stress and ingratiation were presented. Data from a sample of 136 employees at a state lottery organization were used to test the competing models. Support was found for the full mediation model, wherein self-esteem completely mediated the relationship between stress and ingratiation.     

Promoting exercise behavior among Chinese youth with hearing loss: a randomized controlled trial based on the transtheoretical model

The transtheoretical model proposes that behavior change is experienced as a series of stages. Interventions tailored to these stages are most likely to be effective in progressing people through the model's hypothesized behavior change continuum. In this study, a stage-tailored, 12-week, exercise behavior intervention based on the transtheoretical model was conducted among a sample of 150 Chinese youth with hearing loss. Participants were randomized into an intervention or control group with all the core transtheoretical model constructs assessed pre- and post-intervention. Participants in the intervention group showed greater advances in their stage of exercise behavior change, decisional balance, and processes of change use compared to those in the control group. The intervention, however, was insufficient for increasing participants' self-efficacy for exercise behavior. The findings partially support the utility of the theory-based intervention for improving the exercise behavior of Chinese youth with hearing loss, while simultaneously helping to identify areas in need of improvement for future applications.
