Sexual selection: Darwin
- Psychical characteristics aid survival
Anisogamy
- Refers to the differences between male and female sex cells
- Male gametes: highly mobile, vast numbers, little energy needed
- Female gametes: large, static, produced at intervals, limited
- Gives rise to two types of sexual selection
Inter-sexual selection
- Strategies that male use to select females
- Preferred strategies of female
- Trivers: said female make a greater investment of time and commitment-
females choose mate who is genetically fit and will provide resources

Clark and Hatfield- research support
- Sent male and female psychology students across Uni campus
- Asked question ‘’would you like to go to bed with me’’
- No females agreed but 75% men did
- Supports- female pickier then men
Runaway process: females select the tallest males- characteristics become
exaggerated
Fisher: sexy sons hypothesis
- Female who mates with male has characteristics they want there sons to
inherit
Intra-sexual selection
- Male preferred strategy
- Mate competition

+) Sprecher and Hendrick
- Studied heterosexual dating
- Found strong correlations between measures of stratification and self-
disclosure
- If both partners self-disclosure= more satisfied
- Increase validity of theory
Real world application:
- Helps people improve communication
- Increase intimacy and strengthen bond
- 2 psychologists found- 57% of homosexual men and women said that open
and honest self-disclosure was the main way they maintained and
deepened relationships
