Hemispheric Lateralisation A03 Flashcards
Support - adaptive role
Robert’s et al
Found in lateralised chickens could perform two tasks simultaneously (finding food + being vigilant for predators)
Provides evidence that Brian lat enhances brain efficiency in cog tasks, different use of both hemispheres = adaptive
Allows us to process upright faces friend/not
Research support (fink et al)
Fink et al
Used pet scans during visual processing tasks, global elements (forests) dominated RH
Fine details such as individual tress - dominated LH
Supports idea that LH is analyzer and RH is synthesiser
Lim - Nielsen et al
Found no evidence from 1000 brain spaces aged 7-29 years that there was a dominant side that could create a different personality
Refutes idea of LH and rh being diff
Lim
Chicken study - cannot generalise to humans
Strength
Luck et al
Showed sb patients pefiremed better than normal on some tasks such as being faster at finding odd one out
Because unlike norm - left hemisphere is able to direct analytical tasks better because strategies are tied watered often by inferior rh
