Inspired by socioemotional selectivity theory, we investigated age differences in further investment in failing situations by considering goal type and future time perspective. In Experiment 1, 32 younger and 30 older adults reported their likelihood of continued investing following an unsuccessful investment. Older adults were more willing to invest with emotional goals as opposed to knowledge and unspecified goals, while younger adults showed a greater willingness to invest with emotional and knowledge goals rather than unspecified goals. In Experiment 2, another sample of 32 younger and 34 older adults completed the same decision tasks as those in Experiment 1. After future time perspective restriction, the younger adults made decisions resembling Experiment 1's older adults, while after future time perspective expansion, the older adults behaved like Experiment 1's younger adults. These results indicate that future time perspective modification could reverse participants' goal prioritisation, manifesting in differential willingness to pursue further investment in decision scenarios with different goals. Our results represent important steps towards understanding the mechanism of older and younger adults' further investment in failing situations and illustrate that forging connections between the lifespan theory of motivation and further investment decision is critical for understanding adults' decision behaviours. 相似文献

本研究采用游戏使用习惯问卷筛选暴力电子游戏玩家和对照组被试各24名,利用线索探测范式,探讨了暴力电子游戏玩家对攻击性图片的注意偏向机制。结果发现:(1)与对照组相比,暴力电子游戏玩家对攻击性图片线索下探测目标诱发的P1潜伏期提前;(2)暴力电子游戏玩家表现出特定的脑电模式:N1潜伏期延长,P2波幅减小,P300波幅降低;(3)线索的有效性效应表现在早期ERP成分(P1)中。结果表明,暴力电子游戏玩家对攻击性图片表现出注意偏向,其脑电模式揭示暴力电子游戏对玩家的认知功能有消极影响。 相似文献

Socioemotional Selectivity Theory (Carstensen, L. L., Isaacowitz, D. M., & Charles, S. T. (1999). American Psychologist, 54, 155–181) posits that older adults, and anyone else who perceives their time as limited, show a motivational shift toward
emotion regulation which causes them to exhibit a positivity bias and negativity avoidance in attention and memory. We tested
whether such a motivational shift can indeed cause changes in emotional processing by manipulating motivation in a sample
of young adults. After the manipulation, participants looked at real-world images while their eye movements were tracked.
It was found that participants motivated to regulate emotion attended less to negative than positive images and showed less
looking time to all stimulus types compared to the other two conditions. No evidence was found linking the motivational manipulation
to emotional memory.

Computerized adaptive testing for cognitive diagnosis (CD-CAT) needs to be efficient and responsive in real time to meet practical applications' requirements. For high-dimensional data, the number of categories to be recognized in a test grows exponentially as the number of attributes increases, which can easily cause system reaction time to be too long such that it adversely affects the examinees and thus seriously impacts the measurement efficiency. More importantly, the long-time CPU operations and memory usage of item selection in CD-CAT due to intensive computation are impractical and cannot wholly meet practice needs. This paper proposed two new efficient selection strategies (HIA and CEL) for high-dimensional CD-CAT to address this issue by incorporating the max-marginals from the maximum a posteriori query and integrating the ensemble learning approach into the previous efficient selection methods, respectively. The performance of the proposed selection method was compared with the conventional selection method using simulated and real item pools. The results showed that the proposed methods could significantly improve the measurement efficiency with about 1/2–1/200 of the conventional methods' computation time while retaining similar measurement accuracy. With increasing number of attributes and size of the item pool, the computation time advantage of the proposed methods becomes more significant. 相似文献

对三维心理旋转操作任务特性的效应的初步研究 总被引:7,自引:2,他引:5
在认知心理学领域,对心理旋转的研究主要是以反应时范式为基础。本研究试图突破反应时范式,把心理测量学和实验的方法相结合,以现代测量理论——项目反应理论的项目参数(如项目难度、区分度、猜测参数)为指标,对心理旋转测验中,操作任务的若干特性对测验项目特性的影响进行研究,结果发现:对于以Shepard三维旋转材料编制的心理旋转测验、测验材料的复杂程度,标准图形和匹配图形的角度差,以及匹配图形的编排位置等对测验项目的诸特性均无显著影响。 相似文献
