Re-examining Citizenship: How the Control of Measurement Artifacts Affects Observed Relationships of Organizational Citizenship Behavior and Organizational Variables

We examined the impact that measurement artifacts (antithetical items that overlap counterproductive work behavior (CWB), agreement response, halo in supervisor ratings) in organizational citizenship behavior (OCB) measures has on observed relationships between OCB and 15 predictors. Respondents were 146 employees and their supervisors who completed surveys that included OCB measures with and without artifacts. Predictors (conscientiousness, emotional stability, empathy, distributive justice, procedural justice, role ambiguity, role conflict, leader–member exchange, affective organizational commitment, job satisfaction, negative and positive emotion, turnover intention, CWB, and task performance) were chosen that related to OCB in prior meta-analyses. Results with the OCB scale with artifacts were consistent with meta-analyses, whereas results with the artifact-controlled OCB scale were not, suggesting that accepted conclusions about OCB’s relationships with many other variables should be reexamined.

An internet survey of emotional health,treatment seeking and barriers to accessing mental health treatment among Chinese-speaking international students in Australia

The present internet survey examined the demographic characteristics of Chinese-speaking international students in Australia, psychological distress levels as measured by the Kessler-10 (K-10) Item scale, help-seeking history and preferences, as well as treatment barriers. Of the 144 respondents, 54% reported high psychological distress (mean K-10 score?=?23.96; SD?=?9.03). However, only 9% of those who were highly distressed reported they had sought mental health services in the past year. While the majority preferred help from informal social networks, they tended to favour mental health services over traditional culture-specific forms of help. Common barriers to accessing mental health services reported by respondents with high psychological distress included costs or transportation concerns, limited knowledge of available services, time constraints, the perception that symptoms were not severe enough to warrant treatment, language difficulties and lack of knowledge of symptoms of psychological distress. Although the majority preferred face-to-face treatments over internet treatments, a considerable percentage of respondents were willing to try either treatment modality. Chinese-speaking international students are a high risk group for developing psychological distress, yet they tend to underuse mental health services. Education about the effectiveness of face-to-face and online treatments may increase treatment seeking by this population.     

Effects of self–other decision-making on time-based intertemporal choice

The effects of self–other decision-making on intertemporal choice have been revealed in many studies using a monetary outcome. However, the outcome of intertemporal choice is not restricted to money; time is also a scarce and nonrenewable resource outcome. Thus, we conducted a series of experiments to address the effects of self–other decision-making on time-based intertemporal choice, a type of intertemporal choice that uses time as an outcome. Over the course of three experiments, differences in self–other decision-making were evidenced. Participants who made decisions for others were more likely to prefer the smaller but sooner (SS) option over the larger but later (LL) option and considered the gain of the SS option to be significantly greater than that of the LL option. Participants who made decisions for themselves were likely to prefer the LL option over the SS option. However, they considered the gains of the LL and the SS option to be indifferent. Changing the role of decision-making could affect the ability of individuals to consider the future consequences of their decisions. The effects of self–other decision-making on time-based intertemporal choice could be explained by the accounts of economic reasoning and construal level theory. The findings indicated that the effects of self–other decision-making on time-based intertemporal choice, which could be generated simply by rewording questions, can help individuals make optimal long-term choices without the need for increased control.     

崇尚科学拒绝伪科学

伪科学(Pseudoscience)一词出现于1844年。我们今天称之为伪科学的许多东西在历史上与科学曾有着千丝万缕的联系,如占星术之于天文学,炼金术之于化学。但是历史上的占星术和炼金术都不是伪科学,只有在科学值得冒充之后,它们有意识地冒充科学才可算是伪科学。面对社会上的日渐泛滥的伪科学,我们不得不提高警惕,利用科学的方法揭露伪科学的真面目。我们迫在眉睫的任务是提高全民族的科学文化素质,提倡科学精神,拒绝伪科学。     

An empirical and computational investigation of perceiving and remembering event temporal relations

Events have beginnings, ends, and often overlap in time. A major question is how perceivers come to parse a stream of multimodal information into meaningful units and how different event boundaries may vary event processing. This work investigates the roles of these three types of event boundaries in constructing event temporal relations. Predictions were made based on how people would err according to the beginning state, end state, and overlap heuristic hypotheses. Participants viewed animated events that include all the logical possibilities of event temporal relations, and then made temporal relation judgments. The results showed that people make use of the overlap between events and take into account the ends and beginnings, but they weight ends more than beginnings. Neural network simulations showed a self-organized distinction when learning temporal relations between events with overlap versus those without.     

Altering element interactivity and variability in example-practice sequences to enhance learning to write Chinese characters

The isolated elements and variability effects of cognitive load theory were used to alter the element interactivity of Chinese characters when instructing novice learners (72 overseas students at a Chinese university) in writing characters using worked examples-practice procedures. A group of characters with more than eight strokes was disassembled into three individual components. Students were required to trace examples and practice writing of either similar sequences of isolated components followed by integrated components of full characters (Isolated–Integrated sequences); variable sequences of isolated followed by integrated components (Variability–Integrated sequences); or conventional Integrated–Integrated sequences of full characters. It was hypothesized that the fully integrated stroke-movements form of example-practice sequences would result in less learning due to a greater cognitive load. The results demonstrated that the participants in both the Isolated–Integrated and Variable–Integrated groups performed significantly better than the Integrated–Integrated group with the Variable–Integrated group outperforming the Isolated–Integrated group.
