Factors affecting Attraction: Self-Disclosure

Why do human romantic relationships endure?

Child-rearing purposes

Relationship definition

The way 2(+) people, groups, or things are connected, interact, and behave towards one another. Includes interpersonal bonds e.g. friendships and romantic partnerships.

Self-disclosure definition

The process of deliberately revealing significant information about oneself that would not normally be known by others. Can be verbal or non-verbal.

Risks of Self-disclosure

• Info can be spread non-consensually

• Leads to a power imbalance

• Can lead to rejection or disapproval

All lead to vulnerability for the sharer

2. (Non-threatening) facts and biological information

Social Penetration Theory

• Altman & Taylor (1973)

• Proposes that relationships develop over time through gradual, reciprocal self-disclosure, moving from surface-level exchanges to deeper intimacy (the 'onion' model).

Onion Analogy (Depth)

1. Superficial Layers- Likes & dislikes

2. Middle Layers- Opinions (e.g. political opinions)

3. Inner Layers- Hopes and fears

4. Core Personality

Breadth and depth aren’t sufficient, there must be a reciprocal element

Strengths of Self Disclosure Theory

• Sprecher and Hendrick (2004) studied heterosexual dating couples and found a strong positive correlation between high levels of self-disclosure and higher relationship satisfaction and commitment.

• Laurenceau et al. (2005) found that self-disclosure and the perception of a partner's disclosure were linked to higher levels of intimacy in long-term married couples, adding concurrent validity to the theory

• Relationship Counselling: The theory has practical applications for improving troubled relationships. Couples who struggle with superficial "small talk" can be taught to gradually increase reciprocal self-disclosure to deepen their mutual satisfaction and emotional commitment

• Clear Framework: Altman and Taylor’s Social Penetration Theory provides a clear, structured model (the "onion metaphor") breaking down how relationships progress through different levels of breadth and depth.

• Reciprocity Concept: It accounts for the dynamic nature of early attraction by highlighting reciprocity—the idea that balanced, mutual sharing builds the trust necessary for a relationship to grow

Weaknesses of Self-disclosure theory

• Cultural Bias: The theory assumes that increasing the depth and breadth of self-disclosure always leads to more satisfying intimate relationships. This reflects Western, individualistic cultural norms and is not universal. Research by Tang et al. (2013) found that individualist and collectivist cultures view and use self-disclosure differently, meaning the theory lacks cross-cultural validity.

• Issues of Causality: Much of the evidence supporting the theory (such as work by Sprecher and Hendrick) is correlational. This means researchers cannot prove that high self-disclosure causes greater relationship satisfaction. It is equally possible that a pre-existing high level of attraction causes people to disclose more, or that a third variable (like time spent together) influences both.

• Reductionist Approach: The theory reduces romantic attraction and relationship satisfaction down to a single main factor. It ignores other important influences on relationship formation, such as physical attractiveness, attitude similarity, and complementarity.

• Nomothetic Limitation: By trying to create a universal law of how relationships develop through peeling back layers of disclosure, the theory takes a nomothetic approach. It ignores individual differences in personality and personal boundaries, as some people are naturally more private or cautious about when and how they share personal details
