Decision making usually involves uncertainty and risk. Understanding which parts of the human brain are activated during decisions under risk and which neural processes underly (risky) investment decisions are important goals in neuroeconomics. Here, we analyze functional magnetic resonance imaging (fMRI) data on 17 subjects who were exposed to an investment decision task from Mohr, Biele, Krugel, Li, and Heekeren (in NeuroImage 49, 2556–2563, 2010b). We obtain a time series of three-dimensional images of the blood-oxygen-level dependent (BOLD) fMRI signals. We apply a panel version of the dynamic semiparametric factor model (DSFM) presented in Park, Mammen, Wolfgang, and Borak (in Journal of the American Statistical Association 104(485), 284–298, 2009) and identify task-related activations in space and dynamics in time. With the panel DSFM (PDSFM) we can capture the dynamic behavior of the specific brain regions common for all subjects and represent the high-dimensional time-series data in easily interpretable low-dimensional dynamic factors without large loss of variability. Further, we classify the risk attitudes of all subjects based on the estimated low-dimensional time series. Our classification analysis successfully confirms the estimated risk attitudes derived directly from subjects’ decision behavior. 相似文献

Previous studies have found that ego depletion increases dishonesty. However, it remains unclear whether ego depletion makes participants unable to exert self‐control or unwilling to exert self‐control when it increases dishonesty. The present study aimed to clarify this. Based on the process model, ego depletion causes individuals to pay more attention to material rewards and increases the motivation to act on impulse. Therefore, it is possible that ego‐depleted participants are unwilling, rather than unable, to be honest. We conducted two experiments to examine this hypothesis. Results showed that ego depletion increased material‐based dishonesty even when the dishonest behavior was more complicated and effortful than was the honest behavior. However, participants were reluctant to cheat just for convenience, and ego depletion had no apparent effect on convenience‐based dishonesty without any material rewards. The theoretical implications and future directions of these results are discussed. 相似文献

本文是用纵向法,对一个儿童(三周岁至四周岁)掌握数概念的过程,进行追踪研究提出的报告。 研究结果表明:三周岁至四周岁儿童有可能、有必要掌握最初的数概念。数概念广度的发展,是有一定程序的;数概念水平的深化,是通过对计数、取物、比较、运算和读写诸环节的训练而实现的,是从计数活动开始的。掌握数概念,不是自发的、生理成熟的表现,是后天训练、学习的结果。认读数字表,在突破难点时,起相当大的作用。掌握数概念就是掌握有关数的知识,是认识过程,其中动作和记忆具有特别突出的地位。 相似文献

听写困难是指儿童能够认读不能听写的现象。本研究以部件启动和整字启动任务中的探测字命名反应时差值,作为整体字形加工水平的指标,间接考察了听写困难儿童的整体字形加工特点。结果发现,听写对照组被试的整体字形加工在呈现时间为75 ms和300 ms时发生,而在150 ms时没有发生;听写困难组被试的整体字形加工仅在75 ms时发生,而在150 ms和300 ms时未发生。两组被试在75 ms时的整体字形加工水平之间没有显著差异。结果表明,听写困难被试仅仅在早期知觉阶段存在整体字形加工,而在词汇加工阶段的整体字形加工缺乏或延迟。 相似文献

It has been unclear whether an associations of child ADHD with socio-economic disadvantage (SES) could be accounted for by (a) parental ADHD explaining both low SES and child ADHD, and/or (b) the joint overlap of ODD or CD with low SES and ADHD. Study 1 used a community-recruited case-control sample with detailed evaluation of SES indicators, child ADHD, child externalizing, and parent ADHD symptoms (n = 931 children, 521 ADHD, 577 boys, 354 girls) in a path modeling analysis with latent variables. Study 2 evaluated ADHD and externalizing behavior in a regression model using a poverty index for SES, in 70,927 children (48.2% female) aged 5–17 years from the US 2011–2012 National Survey of Children’s Health (NSCH). In Study 1, lower SES was related to the ADHD latent variable, β = ?.18, p < .001; 95%CI [?.25,-.12]. This effect held when parent ADHD and child ODD and CD were in the model, β = ?.11, p < .01, 95% CI [?.09,-.03], equivalent to OR = 1.50, 95% CI[1.12–2.04]). In Study 2, these results replicated. Adjusting only for age and sex, children from families who were below 200% of the federal poverty line were more likely to have moderate or severe ADHD than no ADHD, versus children above that line, OR = 2.13, 95% CI[1.79,2.54], p < .001. The effect held after adjusting for disruptive/externalizing problems, OR = 1.61, p < .01, 95%CI [1.32,1.96]. The effect size for comparable models was similar across both studies, lending higher confidence to the results. It is concluded that the SES association with child ADHD is not explained by artifact and requires a mechanistic explanation. 相似文献
