The Effect of implementation intention on speeding behavior: a simulator study

Tekeş, Burcu
Intention was accepted as the major contributor to driver behaviors in the literature. The present thesis aimed to systematically review the literature on the association between intention and speeding behavior. Based on the results of the review, intention was found as the main contributor of speeding. In the next chapter, intention was aimed to manipulate by implementation intention to reduce speeding. Implementation intentions are self-regulatory ‘if-then’ plans, which are the subordinate concept of goal intentions. Additionally, implementation intention was divided as approach and avoidance goals to compare their impact on the subsequent behavior. A randomized controlled design was used and both self-reported and simulated driver behavior were measured at baseline and follow-up levels. In baseline level, participants in experimental group were manipulated by implementation intentions using a volitional help sheet, which they matched the critical items with appropriate responses, whereas participants in control group received a filler task. After a two-week time-interval, follow-up level of the study was conducted. According to the results, implementation intention can promote a goal attainment in the context of speeding, which is important for road safety. Also, the differentiation between approach and avoidance goals in speeding was found as effective in support of approach goals, but the efficacy of avoidance goals was found as context-specific which covers situations related to pedestrians. Lastly, the previous preferences on speed choices can affect the goal attainment and both reduce or increase the efficacy of implementation intention. The results were discussed in the context of the related literature.
