How we choose one over another: predicting trial-by-trial preference decision.

ABSTRACT: Preference formation is a complex problem as it is subjective, involves emotion, is led by implicit processes, and changes depending on the context even within the same individual. Thus, scientific attempts to predict preference are challenging, yet quite important for basic understanding of human decision making mechanisms, but prediction in a group-average sense has only a limited significance. In this study, we predicted preferential decisions on a trial by trial basis based on brain responses occurring before the individuals made their decisions explicit. Participants made a binary preference decision of approachability based on faces while their electrophysiological responses were recorded. An artificial neural network based pattern-classifier was used with time-frequency resolved patterns of a functional connectivity measure as features for the classifier. We were able to predict preference decisions with a mean accuracy of 74.3 ± 2.79% at participant-independent level and of 91.4 ± 3.8% at participant-dependent level. Further, we revealed a causal role of the first impression on final decision and demonstrated the temporal trajectory of preference decision formation.

Project description:Currently, almost every third child in Germany is delivered by caesarean section. Apart from straightforward and clear indications for caesarean section which account for approx. 10%, the large proportion of relative indications in particular needs to be critically reviewed if the current C-section rate is to be effectively lowered. It is more than doubtful, however, whether this can be a realistic goal in Germany, especially in the context of international developments. All studies on this topic demonstrate that the personal attitude of the obstetric team has a considerable influence on the pregnant woman's personally preferred mode of delivery. Therefore, in the first part of the DECISION study, the personal preferences of urogynaecologists were evaluated regarding the best suitable mode of delivery.All 432 delegates at the 9th German Urogynaecology Congress in Stuttgart in April 2017 were invited to participate in an online questionnaire study. The questionnaire was developed especially for this study.Of the 432 registered delegates, 189 (43.8%) participated in the survey. 84.7% (n?=?160) of the study participants would prefer a vaginal delivery, in an otherwise uncomplicated pregnancy. Only 12.2% (n?=?23) opted for an elective caesarean section. The main reasons stated for this decision were concerns about incontinence (87.5%) and pelvic floor trauma (79.2%). Amongst the study participants, 83.6% would like to be part of a risk stratification system presented in the questionnaire which, with the aid of specific parameters, is intended to allow early identification of a population with a high risk of developing pelvic floor disorders. There was also great interest in postpartum pelvic floor recovery (97.8%) and an associated optional pessary therapy (64.4%). The type of delivery already experienced (vaginal delivery vs. primary caesarean section) and parity also reveals to have a significant influence on the personal preferred mode of delivery as well.Urogynaecologists prefer vaginal delivery for themselves. There is a great interest to participate in a risk stratification process in order to approach childbirth in an individualized and risk-adapted manner.

Project description:For more than 60 years, it has been known that people report higher (lower) subjective values for items after having selected (rejected) them during a choice task. This phenomenon is coined "choice-induced preference change" or CIPC, and its established interpretation is that of "cognitive dissonance" theory. In brief, if people feel uneasy about their choice, they later convince themselves, albeit not always consciously, that the chosen (rejected) item was actually better (worse) than they had originally estimated. While this might make sense from an intuitive psychological standpoint, it is challenging from a theoretical evolutionary perspective. This is because such a cognitive mechanism might yield irrational biases, whose adaptive fitness would be unclear. In this work, we consider an alternative possibility, namely that CIPC is -at least partially- due to the refinement of option value representations that occurs while people are pondering about choice options. For example, contemplating competing possibilities during a choice may highlight aspects of the alternative options that were not considered before. In the context of difficult decisions, this would enable people to reassess option values until they reach a satisfactory level of confidence. This makes CIPC the epiphenomenal outcome of a cognitive process that is instrumental to the decision. Critically, our hypothesis implies novel predictions about how observed CIPC should relate to two specific meta-cognitive processes, namely: choice confidence and subjective certainty regarding pre-choice value judgments. We test these predictions in a behavioral experiment where participants rate the subjective value of food items both before and after choosing between equally valued items; we augment this traditional design with both reports of choice confidence and subjective certainty about value judgments. The results confirm our predictions and provide evidence that many quantitative features of CIPC (in particular: its relationship with metacognitive judgments) may be explained without ever invoking post-choice cognitive dissonance reduction explanation. We then discuss the relevance of our work in the context of the existing debate regarding the putative cognitive mechanisms underlying CIPC.

Project description:High-dimensional biological data collection across heterogeneous groups of samples has become increasingly common, creating high demand for dimensionality reduction techniques that capture underlying structure of the data. Discovering low-dimensional embeddings that describe the separation of any underlying discrete latent structure in data is an important motivation for applying these techniques since these latent classes can represent important sources of unwanted variability, such as batch effects, or interesting sources of signal such as unknown cell types. The features that define this discrete latent structure are often hard to identify in high-dimensional data. Principal component analysis (PCA) is one of the most widely used methods as an unsupervised step for dimensionality reduction. This reduction technique finds linear transformations of the data which explain total variance. When the goal is detecting discrete structure, PCA is applied with the assumption that classes will be separated in directions of maximum variance. However, PCA will fail to accurately find discrete latent structure if this assumption does not hold. Visualization techniques, such as t-Distributed Stochastic Neighbor Embedding (t-SNE) and Uniform Manifold Approximation and Projection (UMAP), attempt to mitigate these problems with PCA by creating a low-dimensional space where similar objects are modeled by nearby points in the low-dimensional embedding and dissimilar objects are modeled by distant points with high probability. However, since t-SNE and UMAP are computationally expensive, often a PCA reduction is done before applying them which makes it sensitive to PCAs downfalls. Also, tSNE is limited to only two or three dimensions as a visualization tool, which may not be adequate for retaining discriminatory information. The linear transformations of PCA are preferable to non-linear transformations provided by methods like t-SNE and UMAP for interpretable feature weights. Here, we propose iterative discriminant analysis (iDA), a dimensionality reduction technique designed to mitigate these limitations. iDA produces an embedding that carries discriminatory information which optimally separates latent clusters using linear transformations that permit post hoc analysis to determine features that define these latent structures.
