Reinforcement,Rationality, and Intentions: How Robust Is Automatic Reinforcement Learning in Economic Decision Making?

Reinforcement learning is often observed in economic decision making and may lead to detrimental decisions. Because of its automaticity, it is difficult to avoid. In three experimental studies, we investigated whether this process could be controlled by goal intentions and implementation intentions. Participants' decisions were investigated in a probability‐updating task in which the normative rule to maximize expected payoff (Bayes' rule) conflicted with the reinforcement heuristic as a simple decision rule. Some participants were asked to set goal intentions designated to foster the optimization of rational decision making, while other participants were asked to furnish these goal intentions with implementation intentions. Results showed that controlling automatic processes of reinforcement learning is possible by means of goal intentions or implementation intentions that focus decision makers on the analysis of decision feedback. Importantly, such beneficial effects were not achieved by simply instructing participants to analyze the feedback, without defining a goal as the desired end state from a first‐person perspective. Regarding intentions supposed to shut down reinforcement processes by controlling negative affect, effects were more complex and depended on the specified goal‐directed behavior. The goal intention to suppress the disappointment elicited by negative feedback was not effective in controlling reinforcement processes. Furnishing this goal with an implementation intention even backfired and strengthened unwanted reinforcement processes. In contrast, asking participants to keep cool in response to negative decision outcomes through the use of goal intentions or implementation intentions increased decisions in line with Bayes' rule.

Consumer uncertainty: The influence of anticipatory emotions on ambivalence,attitudes, and intentions

Specific emotions and their combinations have important implications for consumer experiences and decisions. Therefore, emotional response is examined from a future temporal perspective in order to investigate the effect of anticipatory emotions on consumer ambivalence, attitudes, and intentions. In the first study, anticipatory emotions, compared with outcome‐based emotions, are found to be central in prospective consumption situations, and this combination of emotions is most likely to occur when consumers are presented with conflicting information. Furthermore, anticipatory mixed emotions (i.e., anticipatory ambivalence), in contrast to outcome‐based mixed emotions, were the greatest contributor to consumer discomfort and uncertainty regarding future consumption. The second study builds on the first by considering the effect of anticipatory ambivalence on attitudes and intentions in the context of a prospective purchase situation. Ambivalence was found to mediate the effect of evaluative information on intentions, as well as moderate the relationship between attitudes and intentions. Thus, the uncertainty associated with anticipatory emotions negatively affects intentions, as well as the relationship between attitudes and intentions. The theoretical and practical implications are discussed. Copyright © 2013 John Wiley & Sons, Ltd.     

Implementation intentions do not enhance all types of goals: The moderating role of goal difficulty

Three studies tested whether Gollwitzer and Brandst?tter’s (1997) failure to find an implementation effect for easy goals was due to a ceiling effect, to the moderating effect of previously formed habits, or to a moderating effect of earlier implementation intentions. The studies strongly indicated that easy goals did benefit from forming implementation intentions (i.e., specifying where or when one would perform the action). This suggests that Gollwitzer and Brandst?tter’s failure to find significant implementation effects for easy goals was due to a ceiling effect and not to other moderating effects. However, in the three experiments, we found no positive effect of implementation intentions for the enactment of goal-related behavior corresponding to a certain type of difficult goal. More specifically, when the focus was on the outcome of goal-directed action rather than on the goal-directed actions themselves, implementation intentions specifying when or in what conditions the relevant actions were to be performed did not enhance enactment. When the focus was on the goal-directed actions, we replicated the positive effect of forming implementation intentions. We argue that specifying when or where a goal-directed action should be enacted does not enhance enactment when the actor is not aware of the actions that are required to reach the goal. Possibly, implementation intentions specifying what one should do (rather than where or when) might be more helpful to enhance enactment rates of this type of goal.

How formulating implementation plans and remembering past actions facilitate the enactment of effortful decisions

Building on prior research studying effortful decision making and enactment processes (Bagozzi, Dholakia, & Basuroy, 2003; BDB), we identify and provide an in‐depth understanding of two specific self‐regulatory strategies: (1) formulating an implementation plan, and (2) remembering past actions, that decision makers can use in facilitating enactment of effortful decisions. The results of three experiments, in which the decision maker's goal and self‐regulatory strategy were manipulated, showed that for goals that decision makers chose volitionally, the motivational effects of both these strategies lay in increasing levels of proximal implementation‐related variables (implementation intentions, plan completeness, plan enactment, and goal realization) significantly. In contrast, for goals that were assigned to participants, these strategies' motivational effects additionally extended to significantly increasing distal goal‐related variables (goal desire, goal intentions, perceived self‐efficacy, and implementation desires). The theoretical implications of our findings are discussed, and future research opportunities are explored. Copyright © 2007 John Wiley & Sons, Ltd.     

Consumer decisions in relationships

Most research on consumer choice assumes that decisions are usually made by individuals, and that these decisions are based on an individual's personal attitudes, beliefs, and preferences. Yet, much consumer behavior—from joint decisions to individual choices—is directly or indirectly shaped by people with whom we have some relationship. In this target article, we examine how each member in a relationship can affect how consumer decisions are made. After reviewing foundational work in the area, we introduce a powerful and statistically sophisticated methodology to study decisions within relationships—a dyadic framework of decision-making. We then discuss how the study of consumer decisions in relationships can be informed by different theories in the relationships field, including attachment, interdependence, social power, communal/exchange orientations, relationship norms, and evolutionary principles. By building on the seminal foundations of prior joint-decision making research with theories and methods from contemporary relationship science, we hope to facilitate the integration of the consumer and relationships literature to better understand and generate novel hypotheses about consumer decisions in relationships.     

Motivational and Volitional Processes in Action Initiation: A Field Study of the Role of Implementation Intentions1

A field study tested Gollwitzer's (1993) proposition that the formation of implementation intentions specifying action opportunities accounts for the speed with which intentions are translated into action. Motivation to resume functional activity was assessed among a general population sample of patients prior to joint replacement surgery. At 3 months following surgery. people who had formed implementation intentions were found to have initiated 18 out of 32 activities sooner than people who had not formed implementation intentions. This difference could not be attributed to differences in motivation between the 2 groups. Evidence also showed that the formation of implementation intentions mediated the effects of behavioral expectation on speed of action initiation.     

What Do We Do Unconsciously? And How?

In this reply, we endorse Chartrand's (2005) taxonomy of conscious awareness for different stages of consumer decisions affected by environmental cues. In addition, we attempt to broaden the scope of this taxonomy by discussing its usefulness for consumer decisions in general. We generally support Simonson's (2005) claim that research based on consumers as conscious decision makers is indeed predictive of a wide variety of behavior. However, we also argue that the importance of consciousness should not be overstated. Conscious processes observed in a research laboratory are not representative of conscious processes in real life. The alternative model to describe effects of the environment on behavior by Janiszewski and van Osselaer (2005) may be useful to explain automaticity in goal‐directed behavior, but it poorly describes other automatic behaviors.     

Planning what not to eat: ironic effects of implementation intentions negating unhealthy habits

The present studies tested the effectiveness of implementation intentions with an "if [situation], then not [habitual response]" structure. Based on ironic process theory and the literature on the processing of negations, it was expected that these "negation implementation intentions" would, ironically, strengthen the habit (situation-response association) one aims to break. In line with the hypotheses, forming negation implementation intentions resulted in cognitive ironic rebound effects as well as behavioral ironic rebound effects compared to an intention only condition or a replacement implementation intention. Additionally, it was found that negation implementation intentions are most likely to result in ironic rebound effects when the habit to be negated is strong. Although implementation intentions are generally highly effective in facilitating behavior change even when this involves breaking unwanted habits, the present research suggests that they are ineffective when they have a negating structure.     

The Effects of Sales Message and Suspicion of Ulterior Motives on Salesperson Evaluation

This research investigates the extent to which a salesperson's presentation and consumer suspicion of ulterior motive affect salesperson evaluations and purchase intentions. Study 1 indicates that a salesperson's presentation plays an essential role in confirming or discontinuing consumer suspicion and that this process has important implications in the formation of salesperson attitudes. Evidence from Study 2 demonstrates that these interaction effects are mediated by persuasion‐motive attributions. The findings also support a direct link between attitude toward the salesperson and purchase intentions. Collectively, these results extend the persuasion literature by demonstrating that suspicion of motive is a dynamic state in which consumers entertain rival hypotheses about the salesperson (e.g., is the salesperson truly motivated to help me, or motivated to make his or her commission?) and that, depending on the degree of suspicion, the same salesperson's tactics will be processed very differently by consumers.     

Nudge to Health: Harnessing Decision Research to Promote Health Behavior

We review selected literature that examines how biases in decision making can be utilized to encourage individual health behavior, such as vaccination, and promote policy decisions, such as resource allocation. These studies use simple interventions to nudge people towards more optimal health decisions without restricting decision‐makers’ freedom of choice. Examples include framing effects, defaults, implementation intentions, position effects, social norm, incentives, and emotions. We suggest that nudges are an effective way to promote healthy behavior.     

Implementation intentions and disengagement from a failing course of action

We explored the consequences of forming implementation intentions that call for action (adjustment of chosen course of action) versus reflection (assessment of the appropriateness of chosen course of action) in situations that activate people's tendency to remain committed to failing courses of action. In Study 1, when negative experiences preceded failure, action and reflection implementation intention participants showed higher rates of disengagement than mere goal intention and no intention participants. However, when positive experiences preceded failure, only action implementation intention participants maintained this high disengagement rate. In Study 2, we observed that time pressure moderated the facilitating effects of action and reflection implementation intentions on disengagement when negative experiences preceded failure. Whereas the effect of action implementation intentions benefited from time pressure, the effect of reflection implementation intentions did not. The present studies construe disengagement as a self-regulation process and highlight the benefits of implementation intentions as a self-regulation tool.

Better to Decide Together: Shared Consumer Decision Making,Perceived Power,and Relationship Satisfaction

Shared consumer decisions, particularly those made with a relationship partner, can be very different from decisions that are made alone. Across multiple studies, we investigate how shared consumer decision making affects perceptions of power and relationship satisfaction. We integrate two streams of research to create a novel theory about consumer decision making and perceived power. Specifically, we suggest that shared consumer decision making combines two necessary components of power—an individual's influence over and a partner's engagement in the decision—and that these combined components drive power perceptions. In other words, individuals who relinquish some control and make a decision with their partner, ironically, perceive having greater power than if they had made the decision alone. We further find that shared decision making and greater perceived power lead to greater satisfaction with the relationship in which the decisions are made. By focusing on consumer decision making within relationships, the current research contributes to the literatures on decision making, social influences in consumer behavior, close relationships, consumer well-being, and power.     

Can implementation intentions help to overcome ego-depletion?

Research on ego-depletion suggests that the ability to self-regulate one’s behavior is limited: Exerting self-control on an initial task reduces performance on a subsequent task that also requires self-control. Two experiments tested whether forming implementation intentions could prevent ego-depletion and/or offset the effects of ego-depletion. Experiment 1 found that participants who formed implementation intentions during an initial ego-depleting task subsequently showed greater persistence on an unsolvable puzzles task compared to participants who did not form implementation intentions. Experiment 2 found that among participants who had been ego-depleted during an initial task, forming implementation intentions improved subsequent performance on a Stroop task to the level exhibited by non-depleted controls. Thus, implementation intentions help to enhance people’s ability to self-regulate their behavior.     

Ambivalence and attitudes in consumer replacement decisions

This research examines consumer replacement decisions and the ambivalence that may accompany such decisions. Durable goods replacement decisions are complex in that they involve two interconnected but distinct subdecisions: whether to replace the good, and what to do with the incumbent possession. This research proposes and tests a decision model that incorporates both of these subdecisions. It also examines sources of conflict associated with the ambivalence that may accompany replacement decisions. In so doing, it describes some potential problems associated with conflict measures that have been previously used in the ambivalence literature and describes methods to avoid these problems. Findings from a longitudinal study demonstrate that a model incorporating elements of both replacement subdecisions offers superior prediction of intentions over a traditional decision model. Findings also reveal that ambivalence may have effects at both the pre- and post-purchase stages of the decision process, and that the relationship between conflict and ambivalence may be more complex than previously recognized.     

Self-regulation of priming effects on behavior

In three experiments, we tested whether people can protect their ongoing goal pursuits from antagonistic priming effects by using if-then plans (i.e., implementation intentions). In Experiment 1, concept priming did not influence lexical decision time for a critical stimulus when participants had formed if-then plans to make fast responses to that stimulus. In Experiment 2, participants who were primed with a prosocial goal allowed a confederate who asked for help to interrupt their work on a focal task for a longer time if they had merely formed goal intentions to perform well than if they had also formed implementation intentions for concentrating on the task. In Experiment 3, priming the goal of being fast increased driving speed and errors for participants who had formed mere goal intentions to drive only as fast as safety allowed or who had formed no goal intentions, whereas the driving of participants who had formed such goal intentions as well as implementation intentions showed no such priming effects. Our findings indicate that implementation intentions are an effective self-regulatory tool for shielding actions from disruptive concept- or goal-priming effects.     

How can the impact of implementation intentions as a behaviour change intervention be improved?

Interventions requesting individuals to form implementation intentions, specific plans regarding how and when to enact behaviour, have been shown to be effective in changing a wide range of health, social, and organisational behaviours. A small proportion of studies have sought to identify, within full-factorial designs, under what circumstances and for whom implementation intention-based interventions are most effective. This review covers this issue. A number of potential moderators of the effects of implementation intentions on behaviour were identified (intentions, motivation type, collaboration, plan reminders, goal type, plan type, conscientiousness, perfectionism, procrastination, stress). Of these, the strength of one's intentions have been tested, and supported, most often as a moderator of implementation intention effects. For some of these moderators (e.g., conscientiousness, goal difficulty) the results were contradictory but for others the results were more consistent (e.g., motivation type, plan reminders). Additional moderators might be identified by comparing effects of implementation intentions across studies.     

Social Influence on consumer decisions: Motives,modes, and consequences

Research on consumer decision making has long recognized the influence of others. In this comment on Simpson, Griskevicius, and Rothman (this issue), we agree with them that consumer decisions are best understood in the social contexts in which these decisions are made. We explain how research on consumer social influence incorporates social motives, and we trace the effects of these motives on consumers’ information processing and their purchase and consumption decisions.     

Implementation intentions, perfectionism, and goal progress: perhaps the road to hell is paved with good intentions

Two studies explored whether perfectionism moderates the impact of implementation intentions on goal progress. Study 1 used an implementation intention manipulation to examine the effects of these plans in interaction with perfectionism on the progress of New Year's resolutions. Study 2 added a repeated implementation intention condition and monitored affect and monthly goal progress. The results of both studies revealed a significant backfire effect of the implementation intentions on goal progress for participants high on a particular dimension of perfectionism (socially prescribed perfectionism). These perfectionists reported doing significantly worse at reaching their personal goals when they were asked to formulate implementation intentions than when they completed a control exercise. There also was evidence that implementation planning aroused negative affect for socially prescribed perfectionists. These results are the first to suggest that implementation planning may be contra-indicated for individuals with self-critical tendencies.     

What goes around comes around: The integrated role of emotions on consumer ethical decision‐making

The current study aims to further our understanding of the integrated role of emotions on consumer decision‐making involving ethical issues, by considering the influence of both positive and negative emotions on ethical decision‐making process. It considers not only the emotions experienced prior to ethical decision‐making (pre‐decision emotions) but also those resulting from the course of action chosen (post‐decision emotions). Scenarios are used, and the results of the structural modelling analyses support the proposed relationships between current emotions, consumers' ethical decision‐making, post‐decision emotions and future ethical behavioural intentions. The data suggest the possible existence of a “virtuous ethical cycle”, whereby positive emotions lead to more ethical consumer decisions and behaviours; and these in turn lead to more positive (post‐decision) emotions, which have a positive and significant effect on future ethical behavioural intentions. In addition, happiness emerges as exerting a pivotal role in predicting consumer ethical decisions.
