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

This paper investigates the possible impact of C.G. Jung’s Tavistock Lectures on Bion’s concept of the living container. In the first part of the paper the author argues for clues pointing to such an essential impact, by means of text passages as well as the facts of the Bion-Beckett case, up to and including issues of Bion’s first publication The imaginary twin. The second part investigates the fate of the assumed cryptomnesia. From this point of view Bion’s concept of the container appears to be the result of growth in the container-contained mode. Finally the author deals with the question whether cryptomnesia in psychoanalytical literature can frequently be seen as the result of psychic growth. 相似文献

Analogue Mental Transformations in 3‐Year‐Olds: Introducing a New Mental Rotation Paradigm Suitable for Young Children

Until now, a successful application of the mental rotation paradigm was restricted to children 5 years or older. By contrast, recent findings suggest that even infants can perform mental rotation. Unlike the methods used in infant studies (looking time), our new research paradigm allows for the measurement and interpretation of reaction times. Kindergartners (aged 3–6 years) were presented with a stimulus configuration on a touchscreen and asked to bring a rotated stimulus into an upright position using the shortest path. Mean reaction time (RT) increased linearly with angular disparity. The ensuing linear trend was significant not only for the entire sample but also for the youngest age group analysed separately. To exclude the possibility that linearity was due to movement planning, 3‐year‐olds had to manually rotate a stimulus about the same trajectory without the need for a corresponding mental transformation in a second experiment. Here, no linear trend was observed. These results are interpreted as evidence for an analogue mental transformation in 3‐year‐olds, equal to the transformation processes in older children's and adults' mental rotation.

When performing jointly on a task, human agents are assumed to represent their coactor’s share of this task, and research in various joint action paradigms has focused on representing the coactor’s stimulus–response assignments. Here we show that the response–effect (R–E) contingencies exploited by a coactor also affect performance, and thus might be represented as if they were used by oneself. Participants performed an R–E compatibility task, with keypresses producing spatially compatible or incompatible action effects. We did not observe any R–E compatibility effects when the task was performed in isolation (individual go–no-go). By contrast, small but reliable R–E compatibility effects emerged when the same task was performed in a joint setting. These results indicate that the knowledge of a coactor’s R–E contingencies can influence whether self-produced action effects are used for one’s own motor control. 相似文献

The article shows that the registered juvenile delinquency has decreased in recent years. Serious violent crime partially exists, but this is only a small part of the overall juvenile delinquency. Forms of appearance of these violent crimes are outlined. With the help of a dark field study it is illustrated that there is a great variety of delinquency among young people. There are young people showing mostly law-abiding behavior, infrequent offenders and a group with a significant burden of crimes. 相似文献

In order to yield equal loudness, different studies using scaling or matching methods have found binaural level differences between monaural and diotic presentations ranging from less than 2 dB to as much as 10 dB. In the present study, a reaction time methodology was employed to measure the binaural level difference producing equal reaction time (BLDERT). Participants had to respond to the onset of 1-kHz pure tones with sound pressure levels ranging from 45 to 85 dB, and being presented to the right, the left, or both ears. Equal RTs for monaural and diotic presentation (BLDERTs) were obtained with a level difference of approximately 5 dB. A second experiment showed that different results obtained for the left and right ear are largely due to the responding hand, with ipsilateral responses being faster than contralateral ones. A third experiment investigated the BLDERT for dichotic stimuli, tracing the transition between binaural and monaural stimulation. The results of all three RT experiments are consistent with current models of binaural loudness and contradict earlier claims of perfect binaural summation. 相似文献
