Factors affecting attraction in romantic relationships

Attraction plays a crucial role in the formation of romantic relationships. Various elements influence whether individuals are drawn to each other, ranging from physical appearance to personal interactions.

Key elements influencing attraction

• Physical attractiveness:
  • Often a primary factor, physical features can significantly impact initial attraction.
  • Research, such as Cunningham's 1986 study, highlights specific traits like large eyes, small noses, and prominent cheekbones as being associated with attractiveness in women. Additionally, a lower waist-to-hip ratio is generally considered appealing.
• Gender differences in preference:
  • Studies, including work by Buss, suggest that men tend to prioritise physical appearance more than women when considering a partner.
  • However, both genders value attractiveness highly for short-term relationships, as demonstrated by Li and Kenrick's 2006 research where participants prioritised looks for casual partnerships.
• Self-disclosure:
  • Sharing personal thoughts and feelings can enhance attraction.
  • Collins and Miller's 1994 meta-analysis found that individuals tend to feel closer to someone who reveals personal information to them, and disclosing personal details often increases mutual liking.

Filter theory and the stages of relationship development

Filter theory, proposed by Kerckhoff and Davis in 1962, explains how relationships evolve through a series of stages, each narrowing down potential partners based on specific criteria. This model suggests that different factors become important at different points in the relationship timeline.

Stages of filter theory

• Social demographic filter - At the initial stage, individuals form a 'field of availables', which includes potential partners based on shared social and demographic characteristics such as age, location, or religious background. This filter helps identify a broad group of possible matches.
• Similarity in attitudes filter - As relationships progress, the focus shifts to a 'field of desirables'. This stage prioritises shared values, interests, and attitudes, narrowing down the pool to those with whom a deeper connection is more likely.
• Complementarity filter - In longer-term relationships, the emphasis moves to how well partners meet each other's needs. Complementary traits and abilities become crucial, ensuring that both individuals contribute to a balanced and supportive partnership.

Research on filter theory - Kerckhoff and Davis (1962) study

• Method - Surveyed female university students and their male partners who were contemplating marriage, focusing on their personalities, attitudes, and relationship dynamics. A follow-up survey was conducted after 7 months to assess relationship progression.
• Results - Couples together for less than 18 months were more likely to move towards a permanent partnership if they shared similar values. For those together longer than 18 months, complementary needs were a stronger predictor of progression.
• Conclusions - The study supports filter theory by showing that different factors (similarity initially, complementarity later) are critical at various relationship stages.
• Evaluation - While insightful, the theory's applicability was questioned by Levinger et al. (1970), whose replication across other universities found no significant shift in importance between shared values and complementary needs over time.

Supporting evidence - Winch (1958)

• Surveyed 25 recently married couples and found a strong correlation between complementary needs (e.g., one partner needing to nurture and the other needing care).
• This reinforces the complementarity aspect of filter theory.

The matching hypothesis and partner selection

The matching hypothesis, developed by Walster et al. in 1966, suggests that individuals are more likely to form relationships with partners who match their own level of attractiveness. This theory proposes that people seek balance in partnerships based on perceived physical appeal.

Core idea of the matching hypothesis

• Attraction balance - Individuals tend to select partners who are similarly attractive to themselves, avoiding rejection by aiming for someone within their own 'league' of attractiveness.
• Preference vs. reality - While people might desire highly attractive partners, the hypothesis argues that they ultimately settle for someone of comparable attractiveness to ensure mutual interest.

Research on the matching hypothesis - Walster et al. (1966) computer dance study

Method:

• Organised a 'Computer Dance' for 752 university students (378 men and 374 women).
• Ticket sellers secretly rated participants' attractiveness.
• Participants were told a computer matched them based on interests, but pairings were random (except no men were matched with taller women).
• During the event, participants rated their dates, and follow-up contact after 4-6 months checked for further dating interest.

Results:

• Contrary to the hypothesis, similarity in attractiveness did not predict liking or subsequent date requests.
• Instead, more attractive participants were generally more liked and received more follow-up date invitations, regardless of their partner's attractiveness level.

Conclusions:

• The study did not support the matching hypothesis.
• Instead, it indicated a preference for highly attractive partners over matched attractiveness.

Evaluation:

• The artificial setting of the dance lowers ecological validity, as participants did not choose their partners or face typical dating risks.
• Quick attractiveness ratings by ticket sellers may not align with participants' perceptions during the event, affecting reliability.

Research evidence supporting and challenging these theories

Both filter theory and the matching hypothesis have been tested through various studies, with mixed results that provide both support and criticism for their claims about attraction and relationship formation.

Evidence supporting the matching hypothesis

• Murstein (1972) study - Examined 99 real couples and 98 fake couples, asking participants and an independent judge to rate attractiveness. Real couples showed a strong positive correlation in attractiveness levels, supporting the idea of matching.
• White (1980) study - Followed 123 dating couples over 9 months. Those with similar attractiveness at the start were more likely to progress to serious relationships, reinforcing the matching hypothesis.

Evidence challenging the matching hypothesis

• Limitation in focus - Much of the supporting evidence comes from established relationships rather than initial partner selection, which is the primary focus of the hypothesis.
• Walster et al. (1966) findings - As previously discussed, this study found no link between matched attractiveness and relationship success, suggesting a universal preference for high attractiveness over similarity.

Broader implications for filter theory

• Mixed outcomes - While Kerckhoff and Davis's original findings support the staged importance of similarity and complementarity, the lack of consistent replication (e.g., Levinger et al., 1970) suggests that individual differences or cultural factors may also influence relationship progression.
• Practical relevance - Filter theory provides a framework for understanding how relationships evolve over time, highlighting the shift from surface-level similarities to deeper mutual support as partnerships mature.
