Multinational data show that conspiracy beliefs are associated with the perception (and reality) of poor national economic performance

While a great deal is known about the individual difference factors associated with conspiracy beliefs, much less is known about the country-level factors that shape people's willingness to believe conspiracy theories. In the current article we discuss the possibility that willingness to believe conspiracy theories might be shaped by the perception (and reality) of poor economic performance at the national level. To test this notion, we surveyed 6723 participants from 36 countries. In line with predictions, propensity to believe conspiracy theories was negatively associated with perceptions of current and future national economic vitality. Furthermore, countries with higher GDP per capita tended to have lower belief in conspiracy theories. The data suggest that conspiracy beliefs are not just caused by intrapsychic factors but are also shaped by difficult economic circumstances for which distrust might have a rational basis.

Visual discrimination learning with a 1-min delay of reward

Eight rats were successfully trained in a black-white discrimination with a 1-min delay of reward. The procedure was unusual in that the rat spent the delay outside the apparatus in its home cage. Immediately after the rat responded, whether correctly or incorrectly, it was removed from the choice compartment and placed in its home cage. When the delay ended, it was returned to the startbox. If the preceding response had been correct, the rat received a reward of sugar water; otherwise, it was allowed to make another choice response. Mediation by external cues was excluded because there was no difference in the way the rats were treated after a correct or an incorrect response until the delay interval ended. Mediation by proprioceptive stimuli was excluded because position was an irrelevant cue.     

Distraction and time estimation

It is argued that events which occur during an interval of time which is being judged may be classified in terms of their effects on the alertness of the subject, and in terms of the degree to which they distract him from the task of detecting and processing time-relevant cues. A distracting task, defined by the number of arithmetical operations a subject was required to perform, was presented while reproductions of an interval were being made. The data support the prediction that the higher the level of distraction, the less time a subject will judge to have elapsed during an objective period.     

Bayesian Modal Estimation for the One-Parameter Logistic Ability-Based Guessing (1PL-AG) Model

The calibration of the one-parameter logistic ability-based guessing (1PL-AG) model in item response theory (IRT) with a modest sample size remains a challenge for its implausible estimates and difficulty in obtaining standard errors of estimates. This article proposes an alternative Bayesian modal estimation (BME) method, the Bayesian Expectation-Maximization-Maximization (BEMM) method, which is developed by combining an augmented variable formulation of the 1PL-AG model and a mixture model conceptualization of the three-parameter logistic model (3PLM). By comparing with marginal maximum likelihood estimation (MMLE) and Markov Chain Monte Carlo (MCMC) in JAGS, the simulation shows that BEMM can produce stable and accurate estimates in the modest sample size. A real data example and the MATLAB codes of BEMM are also provided.     

Which types of income matter most for well‐being in China: Absolute,relative or income aspirations?

China has experienced remarkable economic growth, but that has not been associated with increases in individual well‐being, implying that well‐being may not be sensitive to increases in absolute income (AI). Thus, the relationship between well‐being and other types of income is worth investigating. This study employed a national sample of 5471 respondents from 31 provinces of China (excluding Hong Kong, Macao and Taiwan) to compare the effects of AI, relative income (RI) and income aspirations (IA) on individual well‐being in China. The results of a hierarchical regression analysis found that, compared to AI and RI, IA explained more variation in well‐being. These findings highlight the importance of IA for well‐being among the Chinese.     

Conformity: moods matter

This study examined the hypotheses that positive mood enhances conformity and that negative mood reduces it. Participants were induced to feel positive, neutral, or negative moods and then answered, in private, six mathematical questions. They observed that wrong answers were unanimously given by five bogus participants for three of the questions. Conformity was measured by whether they indicated the erroneous answers given by these bogus participants in these three questions. The results were supportive of the hypothesis. The current results are consistent with past findings about mood differences in heuristic versus elaborative processing. Copyright © 2007 John Wiley & Sons, Ltd.     

Mobile Cultures of Migrant Workers in Southern China: Informal Literacies in the Negotiation of (New) Social Relations of the New Working Women

In this paper, we analyze the data collected through in-depth interviews of migrant workers in Southern China about their mobile cultures. In particular, we focus on understanding the role that mobile cultures play in female workers’ negotiation of their social and romantic relations and leisure space and how these negotiations are directly or indirectly facilitated by development of informal literacies through their frequent short message service communicative practices. These will help us understand the lifestyle aspirations and life trajectories of the new young working women in China who are experiencing the most rapid socioeconomic changes in society and negotiating their ways of life amidst much tension between old and new values governing lifestyle aspirations, familial, and gender relations.
