Option 1: Relationships Flashcards
What is anisogamy?
Anisogamy refers to the differences between male and female sex cells.
Describe male sex cells.
Male cells (sperm) are small, mobile, and continuously produced from puberty to old age.
Describe female sex cells.
Female cells (ova) are larger, static, and produced at intervals for a limited number of years.
What are the consequences of anisogamy?
There are plenty of fertile males but fewer females, leading to different mating strategies.
What is inter-sexual selection?
Inter-sexual selection is the selection of mates between sexes (e.g., females selecting males or males selecting females).
What is the female strategy in mating?
Females prioritize quality over quantity, making a greater investment of time, commitment, and resources.
Why do females need to be choosier than males?
Females seek a male who will provide healthy offspring and support them with resources.
How do mating preferences impact behaviour?
Preferences of both sexes determine attributes that are passed on, such as height being a marker of fitness in males.
Females who choose the tallest mates will have greater reproductive success and innate preferences are passed on.
What is intra-sexual selection?
Selection of mates within sexes, e.g. males competing with other males for mates.
What is the male reproductive strategy?
Quantity over quality; males do best by reproducing as frequently as possible.
Why is competition necessary for males?
Females are a limited resource and are choosy.
What happens to males who compete successfully?
They pass on their genes to the next generation, perpetuating those traits.
What impact does intra-sexual selection have on mating behavior?
The pressures of intra-sexual selection leads to patterns such as male aggression — the most aggressive males are more likely to reproduce and a male preference for youthful, fertile women because these are signs of fertility leading to reproductive success.
What is self-disclosure?
Self-disclosure refers to revealing intimate information to another person, such as likes, dislikes, hopes, fears, interests, and attitudes.
Why is self-disclosure important in a relationship?
Self-disclosure plays an important role in the development of a relationship as most people are careful about disclosing too much too soon.
What is social penetration theory?
Social penetration theory (Altman and Taylor 1973) describes self-disclosure as a gradual process of revealing your inner self to someone else.
What does revealing personal information signify?
Revealing personal information is a sign of trust.
What happens as romantic partners disclose more information?
They ‘penetrate’ more deeply into each other’s lives, gaining a greater understanding of each other.
What are the two aspects of social penetration theory?
Breadth and Depth
Why is breadth narrow at the start of a relationship?
Breadth is narrow at the start because revealing too much information may be off-putting and lead to one partner quitting the relationship.
What happens to depth of self-disclosure as a relationship develops?
As a relationship develops, more layers are gradually revealed, including intimate information and painful memories.
What is the need for reciprocity in relationships?
Reciprocity is essential for a relationship to develop.
What do Reis and Shaver (1988) suggest about self-disclosure?
They suggest that successful relationships require both broadening and deepening of self-disclosure, along with reciprocity.
What is involved in successful relationships regarding self-disclosure?
Successful relationships involve disclosure from one partner that is received sensitively by the other partner.
