Journal of Dynamic Decision Making https://journals.ub.uni-heidelberg.de/index.php/jddm Journal of Dynamic Decision Making (JDDM) offers a peer-reviewed interdisciplinary open-access publication outlet for research on cognitive and behavioral processes involved in dynamic decision making and complex problem solving.

In this paper, we present a universal frame for understanding stock-flow reasoning in terms of the theory of force dynamics. This deep-level analysis is then applied to two different presentation formats of SF tasks in the context of climate change. We can explain why in a coordinate-graphic presentation misunderstandings occur (“SF failure”), whereas in a verbal presentation a better understanding is found. We end up with recommendations for presentation formats that will help people to better understand SF dynamics. Better public SF understanding might in turn also enhance corresponding public action – such as enhancing pro-environmental actions in relation to climate change.</p> Kurt Stocker Joachim Funke Copyright (c) 2019 Kurt Stocker, Joachim Funke http://creativecommons.org/licenses/by-nc-nd/4.0/ 2019-05-07 2019-05-07 (1) 1 10 10.11588/jddm.2019.1.51357 Collective Risk Social Dilemma: Role of information availability in achieving cooperation against climate change https://journals.ub.uni-heidelberg.de/index.php/jddm/article/view/57360 <p>Behaviour change via monetary investments is a way to fighting climate change. Prior research has investigated the role of climate-change investments using a Collective-Risk-Social-Dilemma (CRSD) game, where players have to collectively reach a target by contributing to a climate fund; failing which they lose their investments with a probability. However, little is known on how variability in the availability of information about players’ investments influences investment decisions in CRSD. In an experiment involving CRSD, 480 participants were randomly assigned to different conditions that differed in the availability of investment information among players. Half of the players possessed a higher starting endowment (rich) compared to other players (poor). Results revealed that investments against climate change were higher when investment information was available to all players compared to when this information was available only to a few players or to no one. Similarly, investments were higher among rich players compared to poor players when information was available among all players compared to when it was available only to a few players or to no one. Again, the average investment was significantly greater compared to the Nash investment when investment information was available to all players compared to when this information was available only to a few players or to no one. We highlight some implications of our laboratory experiment for human decision-making against climate change.</p> Medha Kumar Varun Dutt Copyright (c) 2019 Medha Kumar, Varun Dutt http://creativecommons.org/licenses/by-nc-nd/4.0/ 2019-05-17 2019-05-17 (2) 1 12 10.11588/jddm.2019.1.57360 Evidence for the dynamic human ability to judge another's sex from ambiguous or unfamiliar signals https://journals.ub.uni-heidelberg.de/index.php/jddm/article/view/61118 <p>Humans make decisions about social information efficiently, despite – or perhaps because of – the sheer scale of data available. Of these various signals, sex cues are vitally important, yet understanding whether participants perceive them as static or dynamic is unknown. The present study addressed the related question of how expertise impinges on sex judgements. Participants were asked to target female and male exemplars from a set of own- or other-race hand images. Data show: (1) that the own-race sex categorisation advantage observed previously using face stimuli can occur in relation to hands, and (2) sensitivity of Asian participants, but not Caucasian participants, is dynamic relative to how many fe/males there are in a set. Implications of these findings are discussed as further evidence that there exists a pan-stimulus sex processor, and as fresh evidence that human sex perception can change probabilistically.</p> Justin Michael Gaetano Copyright (c) 2019 Justin Michael Gaetano http://creativecommons.org/licenses/by-nc-nd/4.0/ 2019-07-09 2019-07-09 (3) 1 14 10.11588/jddm.2019.1.61118 Dynamic MouselabWEB: Individualized Information Display Matrixes https://journals.ub.uni-heidelberg.de/index.php/jddm/article/view/63149 <pre style="-qt-block-indent: 0;
