The current study provides evidence that individuals tend to adopt an integrative choice strategy when making sequential decisions under conditions of uncertainty. This contrasts with prior literature which proposes that decisions are made one at a time in isolation from one another (Camerer et al., 1997). By creating an experimental work task where only wage quality and feedback are manipulated, the resulting changes in intertemporal substitution between work and leisure are observed. In Experiments 1-3, a positive relationship between wages and time spent working that did not depend on task experience was observed. These results suggest that decisions are being made in consideration of other decisions, as isolated decisions would yield a negative relationship between wages and time spent working. In Experiment 4 these results were mitigated by the difficulty in differentiating between low and high wage quality days. These findings are taken to suggest that the results of prior studies are primarily due to self-control issues that subjects faced, which are not present in the present study.

There are currently many good methods for solving sequential decision-making problems under certain assumptions on the structure of the incoming data. However, when the avail- able data fails to meet such assumptions, such as when it involves surrogate or proxy signals, involves measuring survival times, or is unstructured such as in the case of image data, these methods fall short. In this dissertation, we aim to address this discrepancy for specific types of complex data, inspired by healthcare settings in which we might encounter such data. We introduce new methods to better learn from incoming and limited data sources in order to make more efficient decisions.The goal of this work is to develop methods that medical professionals can use to better leverage data in order to determine efficacy or necessity of treatment. All three projects included in this dissertation focus on developing adaptive methods that leverage information as it becomes available to update predictions, to ensure that medical professionals can better balance providing effective healthcare with using available resources efficiently. We also focus on quantifying the performance of these algorithms, and identifying the conditions under which it is most beneficial to use these novel strategies instead of currently employed methods.

There are basically two categories of books on decision-making. One tells stories of how intuition guides decision-making. The other delineates a formal approach, based on decision-trees or matrices, often impenetrable to real-life decision makers. This book combines the best elements of both perspectives in a way that can be easily understood by all who are struggling with complex decisions, either as individuals or as organisations. It demonstrates how intuition and psychological insights can be harnessed to design relevant models and decision strategies, and describes how goals can be adequately formed and operationalised. Finally, the book integrates these processes in an analytical framework for decision-making.

Over the past ten years, there has been growing interest in the process of strategic decision-making among both managers and researchers. Strategic decisions are important for five main reasons: They are large-scale, risky and hard to reverse; they are a bridge between deliberate and emerging strategies; they can be a major source of organizational learning; they play an important part in the development of individual managers and they cut accross functions and academic disciplines. Strategic Decisions summarizes the current state of the art in research on strategic decision-making, with chapters prepared by leading strategy researchers. The editors also present implications for current application and proposed directions for future research.

Making strategic decisions is a fundamental skill for leaders and managers. However, in a business environment that is in a constant state of change, making strategic decisions has never been more difficult. Strategic Decision Making addresses this challenge by providing a framework that can be used to make sound decisions in an uncertain world. Structured around the core concepts of framing, experimenting and scaling, this book will ensure that efforts are focused where the need is greatest, that interventions are tested, evaluated and revised if necessary and that successful initiatives are effectively rolled out across the business. Packed with real world examples and backed up by academic research, Strategic Decision Making will allow today's leaders and the leaders of tomorrow to make successful and defensible business choices. It shows how to: avoid decision-making bias, overcome organizational inertia, manage the difficulties of rigid organizational structures and avoid being side tracked by outdated or irrelevant experience. Essential reading for business practitioners and management students alike, this comprehensive guide provides a robust approach to achieving strategic success.

Difficult decisions often require evaluation of samples of evidence that are acquired sequentially. If samples of evidence differ in their reliability and an unlimited number of samples can be acquired sequentially, the optimal decision strategy is to accumulate evidence in units of log likelihood ratio (logLR) until the accumulated evidence exceeds a predefined threshold, or bound. For this dissertation, I hypothesized that the brain makes probabilistic inferences and decisions by such bonded accumulation of evidence. I trained monkeys to make decisions based on a sequential presentation of visual shapes. Shapes conferred probabilistic evidence that differed in predicting which target would furnish a reward. The stream of shape presentation continued until the monkeys indicated their decisions by eye movements. I found that the monkeys terminated their decisions when the cumulative logLR reached a stereotyped bound, on average. Firing rates of neurons in the lateral intraparietal area (LIP) reflected the accumulated evidence (i.e., the cumulative logLR) and also reached a stereotyped level before the monkeys committed to a decision. LIP activity explained the monkeys' choices and reaction times that reasonably approximated those expected by the optimal strategy. Psychophysical bounds for decision termination often decline in a time-dependent manner, which has been hypothesized to reflect a decision-making strategy that incorporates the cost of elapsed time. In the second part of my dissertation, I tested this hypothesis by manipulating time-cost in a perceptual choice reaction-time task. Specifically, I introduced provisional deadlines while human subjects made decisions about the direction of a random-dot motion stimulus. The pattern of choices and reaction times were explained by bounded accumulation of evidence. Termination bounds were found to decline as a function of time, which was exaggerated in response to the time-cost manipulation. In most of the previous studies of decision making in LIP, the monkeys were aware of the specific eye movement that would result from their decisions while they deliberated on the decision. Thus, it remained unknown whether evidence accumulation in LIP neurons was an abstract representation of the decision itself or a reflection of the impending eye movement. I modified the sequential sampling task, by preventing the monkey from planning a specific eye movement while it accumulated evidence. LIP neurons did not show evidence-dependent activity during the early phase of evidence accumulation period although the evidence provided in this phase affected the monkey's ultimate choice. The result suggests that LIP activity does not represent accumulated evidence per se, but only in preparation for an impending saccade. These experiments demonstrate that a bounded accumulation of evidence explains various types of decision-making such as probabilistic inference and perceptual discrimination. For monkeys, the bounded accumulation of evidence is represented in LIP activity when decisions are formed in parallel with a preparation for a specific eye movement.
