Online feedback and the regulation of degrees of freedom in motor control

We tested the hypothesis that the degree to which online feedback is used to control movement influences the regulation of degrees of freedom in a task. Ten participants performed an isometric force production task with their two index fingers with the goal of matching the total force to a target waveform. The role of online feedback was manipulated by changing three factors - the tracking mode, the profile of the target waveform, and the visual gain. The results showed that the coupling between the finger forces was lower in conditions where participants used online feedback to correct their movements compared to conditions where more feedforward strategies were used. The availability of online feedback is dependent on the nature of the task and this contributes to task-dependent changes in the regulation of the degrees of freedom.

Performance goals: The moderating roles of context and achievement orientation

Past research has yielded mixed findings for performance achievement goals. To help resolve this inconsistency, two experiments explored the moderating role of context and individual differences in achievement orientation. Participants in Study 1 pursued either a performance goal or no goal while solving enjoyable puzzles. They did so within either an evaluative or non-evaluative context, and received positive feedback after task completion. Results show that performance goals did not affect performance on the puzzles and undermined interest only when pursued within evaluative contexts by people low in achievement orientation. Study 2 replicated Study 1 and extended it by manipulating outcome feedback valence. Negative feedback given in an evaluative context undermined interest for people high in achievement orientation, but had no effect on those low in achievement orientation. The findings are related to classic achievement motivation findings and current approach-avoidant models of achievement goal theory.     

Personality factors as predictors of pathological gambling

The aim of this study was to investigate the relationship between different personality variables and pathological gambling (PG). The NEO-FFI and measures of impulsivity and sensation-seeking were administered to a sample of pathological gamblers (n = 90) and to a contrast group of non-pathological gamblers (n = 66) matched on sex and age. Gender, age, education level and the personality variables were entered into crude and adjusted logistic regression analyses with PG-status as the dependent variable. The results showed that educational level and all personality variables were significant predictors of PG in the crude analyses, however only four of the 12 significant predictor variables (Neuroticism, Openness, Impulsivity, and need for Stimulus Intensity) remained significant in the adjusted analysis. All predictor variables accounted for 71% of the variance in PG-status. Clinical implications of the findings are discussed.     

Myopic regret avoidance: Feedback avoidance and learning in repeated decision making

Decision makers can become trapped by myopic regret avoidance in which rejecting feedback to avoid short-term outcome regret (regret associated with counterfactual outcome comparisons) leads to reduced learning and greater long-term regret over continuing poor decisions. In a series of laboratory experiments involving repeated choices among uncertain monetary prospects, participants primed with outcome regret tended to decline feedback, learned the task slowly or not at all, and performed poorly. This pattern was reversed when decision makers were primed with self-blame regret (regret over an unjustified decision). Further, in a final experiment in which task learning was unnecessary, feedback was more often rejected in the self-blame regret condition than in the outcome regret condition. We discuss the findings in terms of a distinction between two regret components, one associated with outcome evaluation, the other with the justifiability of the decision process used in making the choice.

Jumping to Conclusions bias,BADE and Feedback Sensitivity in schizophrenia and schizotypy

Several studies about schizophrenia have shown a cognitive bias named “Jumping to Conclusions” (JTC), defined as a decision made quickly on the basis of little evidence that occurs in these patients when performing probabilistic reasoning paradigms. The main objective of this study is to compare JTC bias and BADE (Bias Against Disconfirmatory Evidence) in patients with schizophrenia vs. participants with high/low schizotypy to understand the underlying mechanism of these cognitive biases. Probabilistic reasoning was assessed using a modified version of Drawing to Decision task. In addition to the traditional parameters of this task (Plausibility Rating (PR), Draws to Decision (DTD), BADE) we also calculated new parameters, overall accuracy and one named Feedback Sensitivity (FS) which lower scores shows greater use of feedback. The results of the study suggest a context effect: in the cued condition, there were not main differences between groups. In the uncued condition, we found higher JTC bias at stage 1 for patients. At the same time, PR at first stages related positively with Feedback Sensitivity and negatively with accuracy for patients and high schizotypy participants (high confidence is associated with worse performance and lower feedback use). BADE seems unrelated to JTC bias and FS. The results are discussed in terms of JTC like as a clinical bias and whether patients with schizophrenia are less able to use feedback.     

情绪感染理论研究述评

情绪是一种具有组织性, 深刻内涵, 并且持续变化的心理状态。人们可以通过捕捉他人的情绪来感知周边人的情感变化, 这一交互过程被称为情绪感染。当前关于情绪感染形成机制的理论假设主要包括模仿-回馈机制、联想-学习机制、语言调节联想机制、认知机制、直接诱导机制等, 其中模仿-回馈机制得到了大多数学者们的接受。在情绪感染的形成过程中, 个体差异性、性别、文化构成了主要的调节变量, 它们影响着个体情绪感染的强度变化。近年来, 情绪感染理论研究从个体情绪感染的机制研究转向群体内部个体间的情绪感染交互作用研究, 循环效应被用于解释成员间的情绪感染过程。在未来的研究中, 应注意以下方面：1)个体差异性对情绪感染的感知程度的系统研究; 2)群体成员间的情绪感染机制研究, 特别是群体负面情绪的交互作用研究; 3)情绪感染理论在服务管理等人员交互性强的行业内的实践应用问题。     

Daily and long-term consequences of support seeking in Chinese couples: Between-person differences and within-person processes

It is widely accepted that support-seeking behaviour is culture-specific, such that Asians are less likely to seek support when stressed compared with Westerners. However, mounting evidence is based on the vignette methodology or the cross-sectional survey and utilised students sample. Little is known about how such behaviour manifests in real life and incurs relational consequences. Moreover, psychological theories predict both differences in support-seeking behaviour between persons and the variability of such behaviour within persons. The current study aims to explore between-and within-person associations between support seeking and relationship satisfaction in Chinese couples. Eighty-four Chinese couples reported their daily stressors, support seeking behaviour, and relationship satisfaction every evening for 7 days and overall relationship satisfaction before the diary study and 1 year later. We found that support seeking matters in Asian couples: On days when couples sought more support, they would be more satisfied with their relationship. Notably, no negative associations between couples' own support seeking and partners' relationship satisfaction were found. This study advances our understanding of general and temporal support-seeking processes in Asian couples in the course of everyday life and over time. Results entail important theoretical and practical implications.     

Self‐Stigma,Mental Health Literacy,and Attitudes Toward Seeking Psychological Help

This study examined self‐stigma of seeking psychological help and mental health literacy as predictors of college students’ (N = 1,535) help‐seeking attitudes, with additional attention to psychological and demographic correlates. Results indicated that mental health literacy predicted help‐seeking attitudes above and beyond self‐stigma. Asian American race/ethnicity, male gender, current psychological distress, and help‐seeking history were also significant predictors. Implications for addressing mental health literacy and self‐stigma while attending to demographic and psychological variations in help seeking are discussed.
