Does first-hand evidence undermine young children's initial trust in positive gossip? Evidence from 5- to 6-year-old children.

What happens when children have formed an impression of a peer based on prior gossip, but later learn from direct observation that the gossip is untrue? We interviewed seventy 5- and 6-year-old children in Zhejiang, China. They first heard conflicting positive and negative gossip about an absent third party, and subsequently learned which piece of gossip was true. Initially, both 5- and 6-year-old children tended to endorse the positive rather than the negative gossip. However, when they learned about the inaccuracy of the positive gossip based on their own direct observation, 6-year-old children subsequently doubted it, whereas 5-year-old children showed no such shift. Taken together, the results show that when children decide what gossip to believe, they are initially swayed by its valence but with age they increasingly weigh gossip in relation to their own direct observation.

Development and Reliability and Validity Test to the Parenting Stress Questionnaire for Two-Child Mothers.

China is getting old before it gets rich. Among women of childbearing age, there seems to be little interest in having multiple children, and parenting stress may be one of the reasons. There are differences in the parenting stress felt by mothers with one child and those with two, but there is no questionnaire specifically aimed at the parenting stress felt by mothers of multiples in China. The purpose of the present study is to develop and verify a questionnaire specifically aimed at measuring the stress of two-child mothers in the Chinese context. We chose mothers as participants who were younger than 50 years old and their second child were younger than 18 years old as participants. The initial questionnaire was created after analyzing the results of 83 participants' open questionnaires and 16 participants' qualitative interviews. Item analysis and exploratory factor analysis were conducted with 279 participants. The final questionnaire was created after conducting reliability and validity tests on the responses of 263 participants to 23 items on the questionnaire covering four factors: characteristics of mother, environmental factor, characteristics of child, and relationship between the two siblings. The results of confirmatory factor analysis indicated that the four-factor model fit well (χ2/df = 2.00, CFI = 0.91, TLI = 0.90, SRMR = 0.06, RMSEA = 0.06). McDonald's omega coefficients and split-half reliability coefficients both ranged from 0.50 to 0.95. The questionnaire scores were significantly positively correlated with parental burnout, the regret of having a second child and parenting stress, and were significantly negatively correlated with the intention of having a third child and support for the three-child policy. Overall, the present study confirmed the reliability and validity of the parenting stress questionnaire for two-child mothers, which can be used to measure the parenting stress experienced by mothers of multiples in China.

Optogenetic Dissection of Neural Circuits Underlying Stress-Induced Mood Disorders.

Objectives: This review aims to (i) summarize the literature on optogenetic applications of different stress-induced mood disorder models of the medial prefrontal cortex (mPFC) and its projection circuits, and (ii) examine methodological variability across the literature and how such variations may influence the underlying circuits of stress-induced mood disorders. Methods: A variety of databases (PubMed, Web of Science, Elsevier, Springer, and Wiley) were systematically searched to identify optogenetic studies that applied to mood disorders in the context of stress. Results: Eleven studies on optogenetic stimulation of the mPFC and the effect of its efferent circuitry on anxiety- and depression-like behaviors in different rodent models were selected. The results showed that the optogenetics (i) can provide insights into the underlying circuits of mood disorders in the context of stress (ii) and also points out new therapeutic strategies for treating mood disorders. Conclusions: These findings indicate a clear role for the mPFC in social avoidance, and highlight the central role of stress reactivity circuitry that may be targeted for the treatment of stress-induced mood disorders.
