Bucher, Alica; Voss, Andreas, 2018, "Judging the mood of the crowd: Attention is focused on happy faces [Dataset]",, heiDATA, V1
Previous research on valence biases in face perception revealed inconsistent findings either proposing angry or happy faces to be detected more efficiently. We argue that the typical experimental task in this field, the face-in-the-crowd (FiC) paradigm, lacks ecological validity...

Schwieren, Christiane; Ceccato, Smarandita; Kettner, Sara E. ; Kudielka, Brigitte; Voss, Andreas, 2018, "Social Preferences under Chronic Stress [Dataset]",, heiDATA, V1
Even though chronic stress is a pervasive problem in contemporary societies and is known to potentially precede both adverse psychological as well as physiological conditions, its effects on decision making have not been systematically investigated. In this paper, we focus on the...

Voss, Andreas; Mertens, Ulf K.; Radev, Stefan T., 2018, "Learning the Likelihood: Using DeepInference for the Estimation of Diffusion-Model and Lévy Flight Parameters [Dataset]",, heiDATA, V1
In the corresponding paper, we use the recently develop DeepInference architecture as a general likelihood-free method to estimate parameters of cognitive models. DeepInference is a machine-learning algorithm based on the training of convolutional neural networks. In a first step...

Xu, Yilong; Xu, Xiaogeng; Tucker, Steven, 2018, "Ambiguity Attitudes in the Loss Domain: Decisions for Self versus Others [Dataset]",, heiDATA, V1, UNF:6:SxDjm/HSLtSILr2x39sg5g==
We study whether people’s ambiguity attitudes differ when deciding for themselves or for others in the loss domain. We find no differences in ambiguity attitudes between self- and other-regarding decision-making. Our results are consistent with the loss part of the fourfold patte...

Kocher, Martin G.; Schindler, David; Trautmann, Stefan T.; Xu, Yilong, 2018, "Risk, time pressure, and selection effects [Dataset]", doi:10.11588/data/GBKK4O, heiDATA, V1, UNF:6:pP3XUM9b1UVsjEaoU0RTig==
Time pressure is a central aspect of economic decision making nowadays. It is therefore natural to ask how time pressure affects decisions, and how to detect individual heterogeneity in the ability to successfully cope with time pressure. In the context of risky decisions, we ask...

Kirchmaier, Isadora; Jens Prüfer; Trautmann, Stefan T., 2018, "Religion, moral attitudes and economic behavior [Dataset]", doi:10.11588/data/PJ8CJU, heiDATA, V1, UNF:6:MuyPmqfxkF5LETTP7Zp3OA==
Using data for a representative sample of the Dutch population with information about participants’ religious background, we study the association between religion and moral behavior and attitudes. We find that religious people are less accepting of unethical economic behavior (e...

Trautmann, Stefan T.; Wakker, Peter P., 2018, "Making the Anscombe-Aumann approach to ambiguity suitable for descriptive applications [Dataset]", doi:10.11588/data/HNN1FW, heiDATA, V1
The Anscombe-Aumann (AA) model, originally introduced to give a normative basis to expected utility, is nowadays mostly used for another purpose: to analyze deviations from expected utility due to ambiguity (unknown probabilities). The AA model makes two ancillary assumptions tha...

Apesteguia, Jose; Huck, Steffen; Oechssler, Jörg; Weidenholzer, Elke; Weidenholzer, Simon, 2018, "Imitation of Peers in Children and Adults [Dataset]", doi:10.11588/data/HFTMST, heiDATA, V1, UNF:6:QDuPhtFcF3CPULh+tQIpJQ==
Imitation of the successful choices of others is a simple and superficially attractive learning rule. It has been shown to be an important driving force for the strategic behavior of (young) adults. In this study we examine whether imitation is prevalent in the behavior of childr...

Reischmann, Andreas; Oechssler, Jörg, 2018, "The Binary Conditional Contribution Mechanism for public good provision in dynamic settings - Theory and experimental evidence [Dataset]", doi:10.11588/data/QHN1KT, heiDATA, V1, UNF:6:oGAQOEsaP2z2MtFReyc6Uw==
We present a new and simple mechanism for repeated public good environments. In the Binary Conditional Contribution Mechanism (BCCM), every agent's message has the form, “I am willing to contribute to the public good if at least k agents contribute in total.” This mechanism offer...
