控制幻觉与人格、动机关系研究

目的本研究考察了人格、动机强弱分别与心理控制幻觉之间的关系。方法采用被试内实验设计的方法,用艾森克人格问卷进行测量。结果与结论动机水平的高低与控制幻觉的形成之间存在明确的关系,即前后动机水平的发生变化,信心分差异显著(t=-3.1,p=0.006<0.05),动机越强则产生控制幻觉的倾向性越大;人格中的外倾性,精神质与心理控制幻觉的产生存在显著的正相关(r=0.766,P<0.01;r=0.827,P<0.01);外倾性这一心理特质对控制幻觉的产生有较强的预测作用。     

Money enhances memory consolidation--but only for boring material

Money’s ability to enhance memory has received increased attention in recent research. However, previous studies have not directly addressed the time-dependent nature of monetary effects on memory, which are suggested to exist by research in cognitive neuroscience, and the possible detrimental effects of monetary rewards on learning interesting material, as indicated by studies in motivational psychology. By utilizing a trivia question paradigm, the current study incorporated these perspectives and examined the effect of monetary rewards on immediate and delayed memory performance for answers to uninteresting and interesting questions. Results showed that monetary rewards promote memory performance only after a delay. In addition, the memory enhancement effect of monetary rewards was only observed for uninteresting questions. These results are consistent with both the hippocampus-dependent memory consolidation model of reward learning and previous findings documenting the ineffectiveness of monetary rewards on tasks that have intrinsic value.     

The ideal self at play: the appeal of video games that let you be all you can be

Video games constitute a popular form of entertainment that allows millions of people to adopt virtual identities. In our research, we explored the idea that the appeal of games is due in part to their ability to provide players with novel experiences that let them "try on" ideal aspects of their selves that might not find expression in everyday life. We found that video games were most intrinsically motivating and had the greatest influence on emotions when players' experiences of themselves during play were congruent with players' conceptions of their ideal selves. Additionally, we found that high levels of immersion in gaming environments, as well as large discrepancies between players' actual-self and ideal-self characteristics, magnified the link between intrinsic motivation and the experience of ideal-self characteristics during play.     

Dynamic and quasi-static mechanical properties of fibre-reinforced metallic glass at different temperatures

We have investigated the dynamic and quasi-static mechanical properties of a tungsten fibre-reinforced Zr_41.25Ti_13.75Ni₁₀Cu_12.5Be_22.5 bulk metallic glass composite (W/BMG) at temperatures ranging from 77 to 473?K. It was found that the yield stress and elastic modulus of the composite increase while strain-to-failure decreases with decreasing temperature. Tests under uniaxial dynamic compression showed that the W/BMG has a higher yield stress than under quasi-static compression. It was shown that yielding of the composite material is dominated by a shear banding process in the glass matrix, which is essentially a viscous flow as a consequence of local adiabatic heating. The interval between the nominal testing temperature and the temperature at which shear bands initiate is a key factor affecting the shear banding process, rendering the properties of the W/BMG very sensitive to temperature.

Time-specific Errors in Growth Curve Modeling: Type-1 Error Inflation and a Possible Solution with Mixed-Effects Models

Growth curve modeling (GCM) has been one of the most popular statistical methods to examine participants’ growth trajectories using longitudinal data. In spite of the popularity of GCM, little attention has been paid to the possible influence of time-specific errors, which influence all participants at each timepoint. In this article, we demonstrate that the failure to take into account such time-specific errors in GCM produces considerable inflation of type-1 error rates in statistical tests of fixed effects (e.g., coefficients for the linear and quadratic terms). We propose a GCM that appropriately incorporates time-specific errors using mixed-effects models to address the problem. We also provide an applied example to illustrate that GCM with and without time-specific errors would lead to different substantive conclusions about the true growth trajectories. Comparisons with other models in longitudinal data analysis and potential issues of model misspecification are discussed.

Chinese adolescents with higher social dominance orientation are less prosocial and less happy: A value‐environment fit analysis

This study aims to investigate the relationship between social dominance orientation (SDO) and subjective well‐being among Chinese adolescents (N = 4246), and to examine the mediating role of prosocial behaviour in this relationship. The structural equation model's results showed that SDO was negatively associated with prosocial behaviour and subjective well‐being, that prosocial behaviour was positively associated with subjective well‐being, and also that (low) prosocial behaviour partially mediated the negative relationship between SDO and subjective well‐being. Multi‐group analyses showed that the mediation model was generally similar between boys and girls, but that the negative relationship between SDO and prosocial behaviour was somewhat stronger among girls than boys. This study sheds light on how SDO is associated with positive outcomes among Chinese adolescents and highlights the mediating role of prosocial behaviour as an underlying mechanism between SDO and subjective well‐being. Future studies are needed to further discover the role of culture values in the association between SDO and subjective well‐being.     

Temperament and self‐based correlates of cooperative,competitive and individualistic learning preferences

People vary in the extent to which they prefer cooperative, competitive or individualistic achievement tasks. In this research, we conducted two studies designed to investigate correlates and possible roots of these social interdependence orientations, namely approach and avoidance temperament, general self‐efficacy, implicit theories of intelligence, and contingencies of self‐worth based in others' approval, competition and academic competence. The results indicated that approach temperament, general self‐efficacy and incremental theory were positively related, and entity theory was negatively related to cooperative preferences (|r| range from .11 to .41); approach temperament, general self‐efficacy, competition contingencies and academic competence contingencies were positively related to competitive preferences (|r| range from .16 to .46); and avoidance temperament, entity theory, competitive contingencies and academic competence contingencies were positively related, and incremental theory was negatively related to individualistic preferences (|r| range from .09 to .15). The findings are discussed with regard to the meaning of each of the three social interdependence orientations, cultural differences among the observed relations and implications for practitioners.     

Metacognition and proofreading: the roles of aging,motivation, and interest

The current study examined younger and older adults’ error detection accuracy, prediction calibration, and postdiction calibration on a proofreading task, to determine if age-related differences would be present in this type of common error detection task. Participants were given text passages, and were first asked to predict the percentage of errors they would detect in the passage. They then read the passage and circled errors (which varied in complexity and locality), and made postdictions regarding their performance, before repeating this with another passage and answering a comprehension test of both passages. There were no age-related differences in error detection accuracy, text comprehension, or metacognitive calibration, though participants in both age groups were overconfident overall in their metacognitive judgments. Both groups gave similar ratings of motivation to complete the task. The older adults rated the passages as more interesting than younger adults did, although this level of interest did not appear to influence error-detection performance. The age equivalence in both proofreading ability and calibration suggests that the ability to proofread text passages and the associated metacognitive monitoring used in judging one’s own performance are maintained in aging. These age-related similarities persisted when younger adults completed the proofreading tasks on a computer screen, rather than with paper and pencil. The findings provide novel insights regarding the influence that cognitive aging may have on metacognitive accuracy and text processing in an everyday task.
