Blocked goals, persistent action: Implementation intentions engender tenacious goal striving

Research on goal attainment has demonstrated that people are more likely to reach their goals when they form implementation intentions. Three experiments tested whether implementation intentions lead to tenacious goal striving following blockage of an initial attempt to reach the goal. In all three experiments some participants were instructed to form an implementation intention and other participants were not. Subsequently, the initial goal-directed attempt of all participants was unexpectedly blocked. Experiment 1 found that implementation intentions resulted in more attempts to realize one’s goal. Experiment 2 showed that when participants formed an implementation intention their repeated attempt was acted out as intensely as their first, blocked attempt. Experiment 3 found that implementation intentions still allow people to seize an alternative, more onerous means to realize their intention. These results imply that implementation intention conserve self-regulatory strength. After goal blockage, the remaining strength can be used to continue goal-directed action.     

"Instant success": turning temptations into cues for goal-directed behavior

Contrary to lay intuition, counteractive control theory posits that tempting food cues can help individuals to act in accordance with their long-term dieting goal. However, studies have shown that temptations trigger goal-directed behavior only in successful but not in unsuccessful self-regulators. The aim of the present study was to test whether it is possible to create facilitated temptation-goal associations in unsuccessful dieters using implementation intentions (e.g., "If I see or smell chocolate then I will follow my goal to diet") and whether this indeed stimulates more successful self-regulation. It was found that implementation intentions linking a temptation to a dieting goal lead to self-perceived improved resistance to (Study 1) as well as reduced consumption (Study 2) of tempting snacks compared to a control condition. Moreover, Study 2 revealed that the reduced snack consumption was indeed related to facilitated temptation-goal associations in participants who had formed implementation intentions.     

Effects of implementation intentions on the self-reported frequency of drivers' compliance with speed limits

This study tested the efficacy of implementation intentions in the context of drivers' speeding behavior. Participants (N = 300) completed self-report measures of goal intention and behavior, and they were randomly assigned to an experimental condition, which required them to specify an implementation intention, or a control condition. One month post-baseline, self-reported compliance with speed limits significantly increased for experimental participants but not for control participants. The effects of specifying an implementation intention on behavior increased with the strength of drivers' goal intentions. Finally, analysis of participants' implementation intentions revealed that specifying more behavioral strategies increased the frequency with which participants reported complying with the speed limit. Implications of the findings are discussed in relation to enhancing road safety interventions.     

Staying on track: Planned goal striving is protected from disruptive internal states

Past implementation intention research focused on shielding goal striving from disruptive internal states (e.g., being anxious) by forming if-then plans that link these very states to instrumental coping responses. In the present line of research, we investigated whether planning out goal striving by means of if-then plans specifying opportunities to initiate goal-directed responses also protects goal striving from the negative impact of disruptive internal states. Indeed, in the face of disruptive internal states, participants who had been asked to form implementation intentions that targeted opportunities for initiating goal-directed responses outperformed participants with a mere goal intention to do well on a focal task goal. Actually, implementation intention participants performed as well as control participants who were not burdened by disruptive internal states such as being in a certain mood (Study 1), ego-depleted (Study 2), or self-definitionally incomplete (Study 3). Results are discussed by pointing to the importance of hypo-egoic self-regulation.     

The interplay between goal intentions and implementation intentions

Two studies tested whether action control by implementation intentions is sensitive to the activation and strength of participants' underlying goal intentions. In Study 1, participants formed implementation intentions (or did not) and their goal intentions were measured. Findings revealed a significant interaction between implementation intentions and the strength of respective goal intentions. Implementation intentions benefited the rate of goal attainment when participants had strong goal intentions but not when goal intentions were weak. Study 2 activated either a task-relevant or a neutral goal outside of participants' conscious awareness and found that implementation intentions affected performance only when the relevant goal had been activated. These findings indicate that the rate of goal attainment engendered by implementation intentions takes account of the state (strength, activation) of people's superordinate goal intentions.     

Overcoming the planning fallacy through willpower: effects of implementation intentions on actual and predicted task‐completion times

Previous work has shown that people often underestimate their task‐completion times (Buehler, Griffin, & Ross, 1994 ). The present research examined whether this optimistic bias may be reduced through the formation of implementation intentions. In an experimental study, participants were requested to complete an assignment within a specified time period. Half of these participants made implementation intentions about where and when they would complete the assignment. The remaining participants were simply given the goal of completing the assignment. The results showed that furnishing participants' goals with implementation intentions led to (a) more optimistic completion predictions, (b) an even greater increase in actual rates of goal completion, and, consequently, (c) a significant reduction in optimistic bias in completion predictions. Furthermore, the reduction in optimistic bias among implementation–intention participants was found to be mediated by a smaller number of interruptions while working on the assignment. Together, these findings attest to the importance of implementation planning in overcoming unrealistic optimism in task‐completion predictions. Copyright © 2000 John Wiley & Sons, Ltd.     

Using Implementation Intentions in Shopping Situations: How Arousal Can Help Shield Consumers Against Temptation

Previous research has suggested that individuals who repeatedly experience self‐regulatory failure in purchasing behaviour have trouble shielding themselves against temptations. Because shopping is often accompanied by increased arousal, we examined whether attending to affective arousal could help people keep their attention focused. Before participants completed a visual distraction task embedded in a shopping context, we (i) instructed them to formulate an implementation intention with affective arousal as the eliciting cue and concentrating on the task as the intention; (ii) instructed them to formulate the goal intention of concentrating on the task without mentioning an eliciting cue; or (iii) gave them no further instructions. During the task, we recorded eye movements to measure the time they looked at the target products. The findings suggest that implementation intentions with affective arousal as an eliciting cue enable consumers who repeatedly perceive self‐regulatory failure to focus their attention on their initial shopping goal.

The Promotion of New Behavior by Forming an Implementation Intention: Results of a Field Experiment in the Domain of Travel Mode Choice1

In the context of an experimental field study, it is analyzed whether furnishing a goal intention with an implementation intention (Gollwitzer, 1993) increases the probability that a new behavior is enacted. For this purpose, 90 students who did not normally use public transportation were asked to test (just one time) a special public transportation offer they had never used before. With a nonobstrusive questionnaire manipulation, the subjects of the experimental group were stimulated to form an implementation intention. The results show that forming an implementation intention significantly increases the probability of enacting the goal intention; that is, testing the public transportation offer. The theoretical and practical implications of this finding are discussed.     

When planning is needed: Implementation intentions and attainment of approach versus avoidance health goals

OBJECTIVE: This study tested whether forming implementation intentions is an effective strategy for attaining health goals focused on trying to avoid a negative state. DESIGN: Participants chose to either eat more healthy snacks (i.e., an approach goal) or eat fewer unhealthy snacks (i.e., an avoidance goal) over two weeks and were randomly assigned to create an implementation intention to do this or not. MAIN OUTCOME MEASURES: The authors measured fat and calorie intake after one week and after two weeks. RESULTS: After two weeks, the participants who ate most unhealthily were those who pursued an avoidance goal and did not form an implementation intention. CONCLUSION: These results suggest that forming implementation intentions for avoidance goal pursuit can help people attain important health goals.

Identifying the ‘if’ for ‘if-then’ plans: Combining implementation intentions with cue-monitoring targeting unhealthy snacking behaviour

Implementation intentions aimed at changing unwanted habits require the identification of personally relevant cues triggering the habitual response in order to be effective. To facilitate successful implementation intention formation, in the present study, planning was combined with cue-monitoring, a novel way to gain insight into triggers for unhealthy snacking. It was tested whether keeping a cue-monitoring diary and tailoring implementation intentions accordingly improves plan effectiveness. A 2 Monitoring (cue-monitoring, control)?×?2 Planning (implementation intention, goal intention) between subjects design was adopted. Participants (N = 161) monitored their unhealthy snacking behaviour for a week using either a cue-monitoring or a control diary. Participants then formulated a goal intention or an implementation intention tailored to their personal cue. Snacking frequency and caloric intake from unhealthy snacks were examined using a seven-day snack diary. The results did not indicate an interaction but yielded a main effect of Monitoring. Cue-monitoring either or not combined with implementation intentions reduced unhealthy snacking behaviour compared with control. Findings emphasise the effectiveness of cue-monitoring, suggesting that on the short term, cue-monitoring suffices to decrease unhealthy snacking, without additional benefit from planning. Future research should examine whether supplementing cue-monitoring with implementation intentions is required to establish long-term behaviour change maintenance.     

7–0? That is awful! Should I trust my national team again?: The role of mindsets in team trust

This investigation examined the role of mindsets in team trust after a major loss. It is proposed that individuals can believe that personal characteristics are fixed and that there is not much one can do about it (a fixed mindset) or that personal characteristics are malleable and that one can improve (a growth mindset). The participants, self-identified football fans, were shown a picture of a major loss experienced by the Mexican national team and then answered questions that assessed the participants' team trust, intention to provide future support, and mindsets. We conceptualised mindsets as latent variables and classes to test our hypotheses. The results from the latent variable model showed a significant, positive influence of a growth mindset on team trust. Similarly, the results from the latent class model showed that the class characterised by high levels of a growth mindset was more likely to trust the national team. Regarding intentions to provide future support to the national team, a growth mindset had an indirect, positive effect through its influence on team trust. Similarly, the class with high levels of a growth mindset was more likely to support the national team in the future. The implications for social psychology and consumer behaviour are discussed.     

Evidence that implementation intentions reduce drivers’ use of mobile phones while driving

Implementation intentions are IF-THEN plans that have the potential to reduce mobile phone use while driving and thus contribute towards the prevention of road traffic crashes. We tested whether an intervention, designed to promote the formation of implementation intentions, could reduce drivers’ use of mobile phones. A randomized controlled design was used. The participants (N = 136) were randomised to an implementation intention or a control condition. Self-report questionnaires were administered to all participants at both pre- and one-month post-intervention to measure the use of mobile phones while driving, goal intentions and the theoretically derived motivational pre-cursors of goal intentions (attitudes, subjective norm and perceived behavioural control). Immediately following the pre-intervention questionnaire, the participants in the implementation intention condition (n = 67) were given a volitional help sheet, which asked them to form implementation intentions by specifying target driving situations that tempted them the most to use a mobile phone and linking them with goal-directed responses that could be used to resist the temptation. The participants in the control condition (n = 69) were asked to specify target situations that tempted them the most to use a mobile phone while driving and to generally try to avoid using a mobile phone in those situations. One-month post-intervention, the participants in the implementation intention condition reported using a mobile phone less often while driving in their specified target driving situations than did the participants in the control condition. As expected, no differences were found between the conditions in the reported frequency of mobile phone use in unspecified driving situations, goal intentions or any motivational pre-cursor of goal intentions. The implementation intention intervention that was tested in this study is a potentially effective tool for reducing mobile phone use while driving in target driving situations, where behaviour-change is most needed.     

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.

Preferred Difficulty and Subjective Probability in Different Action Phases

Drawing on Gollwitzer's deliberative–implemental mindset distinction (P. M. Gollwitzer, 1990), it was predicted that people who are deliberating on different actions or goals would be more cautious or more realistic in their expectation of success in subsequent tasks than people who are going to implement a chosen action or goal. Participants were given a choice between different test-materials. They were interrupted before (deliberative) or immediately after decision-making (implemental). They then either had to choose between various levels of difficulty within one type of task (Experiment 1) or they had to predict their own future performance (Experiment 2). The results showed that deliberative participants preferred less difficult tasks and overestimated their probability of success less than implemental participants. In addition, deliberative participants referred more than implemental participants to their past performance when selecting levels of difficulty or predicting future performance; however, the two groups did not differ in actual performance. Taken together, the findings suggest that people are more realistic in a deliberative than in an implemental state of mind. The present studies extend prior research because for the first time they document mindset effects on peoples' estimates concerning their future performance in the achievement domain.     

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.     

Committing to implementation intentions: Attention and memory effects for selected situational cues

Two studies tested whether forming implementation intentions (Gollwitzer, Am Psychol 54:493?C503 in 1999) results in a heightened activation of specified situational cues. Going beyond prior studies, participants of the present studies specified these opportunities on their own (i.e., the action cues were not assigned by the experimenter), and activation level was assessed by attraction of attention and recall performance rather than lexical decisions. In Study 1, situational cues associated with the where and when to act on an everyday life goal attracted more attention than non-specified cues when presented to the non-attended channel in a dichotic listening task. In Study 2, the recall of specified cues was better than that of non-specified cues both 15?min after forming implementation intentions and after a delay of 2?days. Importantly, goal commitment and implementation intention commitment moderated this effect.     

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.     

The effects of implementation intention strategies on prospective memory cue encoding

Implementation intentions, which include a structured verbal statement and mental imagery, improve prospective memory performance (i.e. remembering to execute delayed intentions). To investigate whether, and how, implementation intention strategies affect encoding processes we had participants complete a thought probe procedure immediately after forming the intention to remember to press Q when seeing fruit words. In Experiment 1, an implementation intention verbal statement (relative to control statement) significantly increased generation of high typicality exemplars (apple, banana, orange). In Experiment 2, an implementation intention imagery procedure (relative to control imagery) produced similar outcomes. In Experiment 3, combining the statement and imagery components of the implementation intention (relative to control statement and imagery) demonstrated even more potent effects (e.g. three-fold increase in fruit exemplars generated). In Experiment 4, we tested whether the control statement versus control imagery procedure differentially affected encoding, but these control procedures showed no significant differences. An interesting, unanticipated finding was that there was significantly less mind wandering in the implementation intention conditions relative to the control conditions. The current experiments provide novel information on the processes operating during intention encoding, and support the classic view that implementation intentions increase the encoding of specific retrieval cues.
