Is imagery better than reality? Performance in imagined dart throwing

We investigated whether deviations from optimal performance are predicted in motor imagery. In Experiment 1, novices and experts imagined and executed dart throws. In imagination, they reported the final position of the dart. Experts performed better than novices in execution and imagination. Distance to the target and bias were smaller in imagination than in execution. In Experiment 2, we dissociated the roles of feedback from proximal and distal action elements for predictions. Three groups of novices estimated the dart’s final position in imagination, in execution without visual feedback, or in execution with delayed visual feedback. Estimates did not differ significantly between groups, indicating that (the lack of) feedback did not influence predictions. Deviations from optimal performance were lower in estimated than in actual performance. In conclusion, although predictive mechanisms may be similar in imagination and execution, the full extent of deviation from optimal performance is not predicted.     

社会认知基本维度与主观幸福感：未来时间洞察力的中介作用

基于社会认知双视角模型和人类适应机制,探讨能动性和表达性与主观幸福感的关系及其作用机制,采用社会认知基本维度形容词词库、未来时间洞察力问卷和幸福感指数量表对全国21个省市居民进行调查,共回收有效问卷4071份,其中男性1714人（42.1%）,女性2342人（57.5%）。结果表明：（1）能动性、表达性显著正向预测主观幸福,且能动性的预测效力大于表达性;未来时间洞察力显著正向预测主观幸福感;（2）能动性、表达性能通过未来时间洞察力的中介作用间接预测个人主观幸福感。本研究结果有利于揭示能动性、表达性如何影响个体主观幸福感体验,以及能动性、表达性对主观幸福感的影响程度,对于提升个人主观幸福感有一定启示意义。     

视频游戏中的化身认同

化身认同是个体在使用和体验游戏化身的过程中,自我知觉发生暂时性改变,并与化身在情绪和认知上的联系暂时加强的心理现象,它为理解化身效应提供了新视角。目前,化身认同的测量模型主要有三维和四维结构模型,其神经机制也得到初步揭示。影响化身认同的因素主要包括游戏自身特点和个体因素。影响效果方面,化身认同与游戏体验、游戏成瘾、攻击行为和自我同一性的关系是目前关注的焦点。未来的研究,仍需深入探讨化身认同的概念与结构,研发更加有效的测量工具,拓展研究方法,丰富研究变量,并加强应用研究。     

Comparing positive and negative reinforcement: A fantasy experiment

We propose quantitative experimental approaches to the question of whether positive and negative reinforcement are functionally different, and discuss scientific and ethical concerns that would arise if these approaches were pursued.     

Impact of age-relevant goals on future thinking in younger and older adults

This study investigated how personal goals influence age differences in episodic future thinking. Research suggests that personal goals change with age and like autobiographical memory, future thinking is thought to be organised and impacted by personal goals. It was hypothesised that cueing older adults with age-relevant goals should modulate age differences in episodic details and may also influence phenomenological characteristics of imagined scenarios. Healthy younger and older adults completed the Future Thinking Interview [Addis, D. R., Wong, A. T., & Schacter, D. L. (2008). Age-related changes in the episodic simulation of future events. Psychological Science, 19(1), 33–41. doi:10.1111/j.1467-9280.2008.02043.x] adapted to activate age-appropriate goals. Narratives were scored with an established protocol to obtain objective measures of episodic and semantic details. Subjective features such as emotionality and personal significance showed age differences as a function of goal domain while other features (e.g., vividness) were unaffected. However, consistent with prior reports, older adults produced fewer episodic details than younger adults and this was not modulated by goal domain. The results do not indicate that goal activation affects level of episodic detail. With respect to phenomenological aspects of future thinking, however, younger adults show more sensitivity to goal activation, compared with older adults.     

Exploring the experience of episodic past,future, and counterfactual thinking in younger and older adults: A study of a Colombian sample

Although extant evidence suggests that many neural and cognitive mechanisms underlying episodic past, future, and counterfactual thinking overlap, recent results have uncovered differences among these three processes. However, the extent to which there may be age-related differences in the phenomenological characteristics associated with episodic past, future and counterfactual thinking remains unclear. This study used adapted versions of the Memory Characteristics Questionnaire and the Autobiographical Interview in younger and older adults to investigate the subjective experience of episodic past, future and counterfactual thinking. The results suggest that, across all conditions, younger adults generated more internal details than older adults. However, older adults generated more external details for episodic future and counterfactual thinking than younger adults. Additionally, younger and older adults generated more internal details, and gave higher sensory and contextual ratings, for memories rather than future and counterfactual thoughts. Methodological and theoretical consequences for extant theories of mental simulation are discussed.     

Using accelerator pedal force to increase seat belt use of service vehicle drivers

This study evaluated a device that applied a sustained increase in accelerator pedal back force whenever drivers exceeded a preset speed criterion without buckling their seat belts. This force was removed once the belt was fastened. Participants were 6 commercial drivers who operated carpet-cleaning vans. During baseline, no contingency was in place for unbuckled trips. The pedal resistance was introduced via a multiple baseline design across groups. On the first day of treatment, the device was explained and demonstrated for all drivers of the vehicle. The treatment was associated with an immediate sustained increase in seat belt compliance to 100%. Occasionally, drivers initially did not buckle during a trip and encountered the force. In all instances, they buckled within less than 25 s. These results suggest that the increased force was sufficient to set up an establishing operation to reinforce seat belt buckling negatively. Drivers indicated that they were impressed with the device and would not drive very long unbelted with the pedal force in place.     

Prospective and positive mental imagery deficits in dysphoria

We know less about positive mental imagery than we do about negative mental imagery in depression. This study examined the relationship between depressed mood and the subjective experience of emotion in imagined events; specifically, prospective imagery, and imagery in response to emotionally ambiguous stimuli. One hundred and twenty-six undergraduates completed measures of depression, imagery vividness for future events, and a homograph interpretation task in which they generated images and subsequently rated image pleasantness and vividness. As predicted, compared to low dysphoria, high dysphoria was associated with poorer ability to vividly imagine positive (but not negative) future events. These findings were augmented by the observation that high dysphorics provided lower pleasantness ratings of images generated in response to homographs they interpreted as positive. We suggest that an imbalance in the inability to vividly imagine positive but not negative future events may curtail the ability of high dysphorics to be optimistic. High dysphoric individuals are further disadvantaged: even when they interpret ambiguity positively, the resulting images they generate are associated with less positive affect. Therapeutic strategies that address both such positive-specific imagery biases hold promise for depression treatment innovation.     

开端、裂缝与未来——海德格尔与德里达对"阿那克西曼德之箴言"的双重解读

该文考察了海德格尔与德里达对阿那克西曼德的一条箴言的两种不同解读。海氏从其存在论视野出发,认为该箴言所传达的是古希腊人对于在场与在场者的基本经验。海氏的解读赋予了“聚集”、“嵌合”、“一”以优先性,认为开端处的“裂缝”是消极的、派生的,必须要被克服。但德里达认为海氏的解读错失了另一种本源意义上的“裂缝”。这种“裂缝”不仅不应当被克服,反而应当在开端处就予以保持,如此才能给他者、未来和正义的到来保有一线机会。这两种不同的解读实质上反映了关于开端、历史与未来的两种不同思想。     

New job market entrants' future work self,career adaptability and job search outcomes: Examining mediating and moderating models

Based on career construction theory and the model of proactive motivation, the current research examined the mediating and moderating models for the relations among future work self, career adaptability, job search self-efficacy and employment status. A survey study was conducted among Chinese university graduates (N = 270). The results showed that future work self (measured at wave 1) had positive effect on employment status (measured at wave 3), with this relationship partially mediated by career adaptability (measured at wave 1) and job search self-efficacy (measured at wave 2). In addition, the results further revealed that the positive effect of future work self on job search self-efficacy was stronger among the graduates who had a higher level of career adaptability. In support of the hypothesized moderated mediation model, for individuals with a higher level of career adaptability, the indirect effect of future work self on employment status through job search self-efficacy was stronger. These findings carry implications for research on job search behavior, career education and career counseling.
