If you are going to pay within the next 24 hours, press 1: automatic planning prompt reduces credit card delinquency

People often form intentions but fail to follow through on them. Mounting evidence suggests that such intention-action gaps can be narrowed with prompts to make concrete plans about when, where and how to act to achieve the intention. In this paper we pushed the notion of plan-concreteness to test the efficacy of a prompt under a minimalist automated calling setting, where respondents were only prompted to indicate a narrower duration within which they intent to act. In a field experiment this planning prompt significantly helped people to pay their past dues and get out of debt delinquency. These results suggest that minimalist automatic planning prompts are a scalable, cost-effective intervention.https://onlinelibrary.wiley.com/doi/epdf/10.1002/jcpy.1031Published versio

Giraffes, religion and conflict : essays in behavioral decision making

Thesis (Ph. D.)--Massachusetts Institute of Technology, Sloan School of Management, 2008.Includes bibliographical references.Essay 1: Objective Scale Anchoring in Sequential Judgments We explore the scope and boundary conditions for anchoring when respondents render sequential judgments in the absence of an explicit comparative standard. We show that previous judgments can anchor subsequent ones, even when these are not explicitly compared. We then demonstrate that the effect is caused by the reinterpretation of objective response scales. Much like the use of the label 'very heavy' will depend on its context, we show that the use of labels such as '1000 pounds' will also depend on context. Even though the pounds scale is objectively defined, psychologically it still must be interpreted, and is subject to similar effects as those that influence subjective scales. Essay 2: The Impact of Regular Activities on Well-being Because of people's tendency to adapt, few events in life have a lasting impact on subjective well-being. We suggest that while major events may not provide lasting increases in well-being, certain seemingly minor events - such as attending religious services or exercising - may do so by providing small but frequent boosts. In two studies we demonstrate the existence of such boosts to well-being, and provide evidence that these boosts may be cumulative. We suggest that shifting focus from the impact of major life changes on well-being to the impact of seemingly minor repeated behaviors is crucial for understanding how best to improve well-being. Essay 3: The Doomsday Device: A Mechanism for Avoiding Conflict Arms races are a common occurrence in the business world. In the current paper, we propose that such arms races can be avoided by the use of commitment to an extreme response, and we test this idea experimentally.(cont.) Our findings suggest that actual commitment is an effective but underused tool for avoiding the escalation of conflict. We also find that while cheap talk is not effective in the short run, it is useful for establishing a reputation for future interactions.by Daniel Mochon.Ph.D

Bolstering and Restoring Feelings of Competence via the IKEA Effect

We examine the underlying process behind the IKEA effect, which is defined as consumers' willingness to pay more for self-created products than for identical products made by others, and explore the factors that influence both consumers' willingness to engage in self-creation and the utility that they derive from such activities. We propose that creating products fulfills consumers' psychological need to signal competence to themselves and to others, and that feelings of competence associated with self-created products lead to their increased valuation. We demonstrate that the feelings of competence that arise from assembling products mediate their increased value (Experiment 1), that affirming consumers' sense of self decreases the value they derive from their creations (Experiment 2), and that threatening consumers' sense of self increases their propensity to make things themselves (Experiments 3A and 3B)

The IKEA effect: When labor leads to love

In four studies in which consumers assembled IKEA boxes, folded origami, and built sets of Legos, we demonstrate and investigate boundary conditions for the IKEA effect—the increase in valuation of self-made products. Participants saw their amateurish creations as similar in value to experts' creations, and expected others to share their opinions. We show that labor leads to love only when labor results in successful completion of tasks; when participants built and then destroyed their creations, or failed to complete them, the IKEA effect dissipated. Finally, we show that labor increases valuation for both “do-it-yourselfers” and novices

The Individual Dynamics of Online Reviews

We examine the individual level dynamics of online reviews, using a unique data set of real consumer app reviews. We find that a consumer's review is positively related to their rating of the prior app reviewed, while it is negatively related to the quality of the prior app reviewed

High throughput methods applied in biomaterial development and discovery

The high throughput discovery of new materials can be achieved by rapidly screening many different materials synthesised by a combinatorial approach to identify the optimal material that fulfils a particular biomedical application. Here we review the literature in this area and conclude that for polymers, this process is best achieved in a microarray format, which enable thousands of cell-material interactions to be monitored on a single chip. Polymer microarrays can be formed by printing pre-synthesised polymers or by printing monomers onto the chip where on-slide polymerisation is initiated. The surface properties of the material can be analysed and correlated to the biological performance using high throughput surface analysis, including time-of-flight secondary ion mass spectrometry (ToF-SIMS), X-ray photoelectron spectroscopy (XPS) and water contact angle (WCA) measurements. This approach enables the surface properties responsible for the success of a material to be understood, which in turn provides the foundations of future material design. The high throughput discovery of materials using polymer microarrays has been explored for many cell-based applications including the isolation of specific cells from heterogeneous populations, the attachment and differentiation of stem cells and the controlled transfection of cells. Further development of polymerisation techniques and high throughput biological assays amenable to the polymer microarray format will broaden the combinatorial space and biological phenomenon that polymer microarrays can explore, and increase their efficacy. This will, in turn, result in the discovery of optimised polymeric materials for many biomaterial applications

Overview of recent TJ-II stellarator results

The main results obtained in the TJ-II stellarator in the last two years are reported. The most important topics investigated have been modelling and validation of impurity transport, validation of gyrokinetic simulations, turbulence characterisation, effect of magnetic configuration on transport, fuelling with pellet injection, fast particles and liquid metal plasma facing components. As regards impurity transport research, a number of working lines exploring several recently discovered effects have been developed: the effect of tangential drifts on stellarator neoclassical transport, the impurity flux driven by electric fields tangent to magnetic surfaces and attempts of experimental validation with Doppler reflectometry of the variation of the radial electric field on the flux surface. Concerning gyrokinetic simulations, two validation activities have been performed, the comparison with measurements of zonal flow relaxation in pellet-induced fast transients and the comparison with experimental poloidal variation of fluctuations amplitude. The impact of radial electric fields on turbulence spreading in the edge and scrape-off layer has been also experimentally characterized using a 2D Langmuir probe array. Another remarkable piece of work has been the investigation of the radial propagation of small temperature perturbations using transfer entropy. Research on the physics and modelling of plasma core fuelling with pellet and tracer-encapsulated solid-pellet injection has produced also relevant results. Neutral beam injection driven Alfvénic activity and its possible control by electron cyclotron current drive has been examined as well in TJ-II. Finally, recent results on alternative plasma facing components based on liquid metals are also presentedThis work has been carried out within the framework of the EUROfusion Consortium and has received funding from the Euratom research and training programme 2014–2018 under Grant Agreement No. 633053.

Single Option Aversion

Single Option Aversion Daniel Mochon, Tulane University, USA Single option aversion is a context effect whereby consumers are unwilling to choose an attractive option when no competing options are included in the choice set. Consequently, an option may be chosen more often when competing options are added. This effect has unique practical and theoretical implications for consumer search
