Endocrinology - Testos & digit ratio
3 important questions on Endocrinology - Testos & digit ratio
Explain finger ration measurement.
- 2nd (point finger)/4th (ring finger)
- prenatale testosterone makes your pointer finger shorter
- estradiol makes your ring finger shorter
=> there is some evidence that digit ratio of homosexual men is mor similar to digit ratio of women.
Explain cognitive empathy task. (Baron Cohen; reading the mind in the eye task)
- Oxytocine improved "mind-reading" tasks
- Testosterone does the exact opposite
- Females impair in cog-empathy when administered with testos
How is digit ration used in the cognitive empathy task?
- Used as a predictor
- low digit ratio (=prenatal primed with testos) show strongest effect of testos manipulation
- translates to rodents' studies with prenatale testos manipulation: in later life more sensitive to testos
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
