Attachment Style Questionnaire
The same scale used in the previous studies was used to assess attachment style. The items measuring anxious attachment showed good internal reliability, α=.91. The items measuring avoidant attachment also showed good internal reliability, α = .87.
Filler task
Participants then completed a filler task between the questionnaires and the moral dilemma. The purpose of this task was to clear working memory, thereby reducing potential contamination between the Adult Attachment Scale and participants' moral judgments. On this task, participants unscrambled 10 incoherent letter strings into actual words. Participants were given five minutes to complete this task. Whether or not the participant had completed all ten word puzzles, the experiment continued once the five minutes had elapsed. Next, participants were randomly assigned to one of three experimental conditions in which the content of the moral dilemma was altered.
