Sternberg's Triangular Theory of Love

We typically love the people with whom we form relationships, but the type of love we have for our family, friends, and lovers differs. Robert Sternberg (1986) proposed that there are three components of love: intimacy, passion, and commitment. These three components form a triangle that defines multiple types of love: this is known as Sternberg’s triangular theory of love. Intimacy is the sharing of details and intimate thoughts and emotions. Passion is the physical attraction—the...

This distress often intensifies in romantic breakups, where the initiator may experience greater turmoil than the rejected partner. Contributing factors include residual attachment, guilt over causing pain, and uncertainty about how to manage the situation. The stress is further...

Pharmacokinetic–Pharmacodynamic Relationship: Duration of Dose-Effect Relationship

24
For drugs producing a quantal response, onset occurs when plasma concentration reaches a minimum effective level (Cmin). The drug's action duration depends on how long the plasma concentration remains above Cmin.Two primary factors influence this duration: dose size and the rate of drug removal from the action site. Both depend on the drug's redistribution to poorly perfused tissues and elimination processes. A larger dose promotes rapid onset and prolongs the effect's duration.Consider a...

Relationship Growth

Interpersonal relationships progress through stages, beginning with awareness and moving toward mutuality, where emotional connections deepen. While many relationships remain at moderate levels of mutuality, deeper connections form through self-disclosure, trust, and interdependence.Self-DisclosureSelf-disclosure involves revealing personal information, starting with surface-level details and gradually progressing to more intimate content. As trust grows, individuals feel more comfortable...

Area of Science:

  • Psychology
  • Social Psychology
  • Relationship Science

Background:

  • Intimacy and passion are key components of romantic relationships.
  • Previous research suggests a connection, but the causal direction is debated.

Purpose of the Study:

  • To investigate the association between intimacy and passion in couples.
  • To test if increases in intimacy generate passion.
  • To examine partner effects in the intimacy-passion dynamic.

Main Methods:

  • Diary study with 75 couples over 14 days.
  • Dyadic multilevel analyses were employed.
  • Residualized change scores were used to analyze intimacy and passion.

Main Results:

  • Both actor's and partner's intimacy change positively predicted actor's passion.
  • Residualized passion change also positively predicted intimacy.
  • A bidirectional relationship between intimacy and passion was observed.

Conclusions:

  • Findings provide empirical support for the intimacy change model.
  • The study highlights a reciprocal relationship between intimacy and passion.
  • It remains challenging to definitively determine whether intimacy drives passion or vice versa.
