The chapter explores the implications of working models of attachment on social perception, emotion, and behavior. Two studies were conducted to examine how attachment styles influence the interpretation and explanation of relationship events. Study 1 found that preoccupied participants explained events more negatively and reported higher emotional distress, while avoidant participants provided negative explanations but did not report emotional distress. Path analysis showed that attachment style differences in behavior were mediated by explanation patterns and emotional distress. Study 2 replicated these findings and found that both attachment style and relationship quality were significant predictors of explanations, but only attachment style predicted emotional responses. These results suggest that adults with different working models of attachment are predisposed to think, feel, and behave differently in their relationships. The chapter also discusses the broader model of social functioning, including cognition, affect, and behavior, and proposes a model linking attachment style, explanation patterns, emotional responses, and behavioral intentions. The findings highlight the importance of attachment theory in understanding social functioning and relationship quality in adulthood.The chapter explores the implications of working models of attachment on social perception, emotion, and behavior.
