Psychology 9-1 GCSE - 4.2.2 - Sperry (1968) Hemisphere Deconnection and Unity in Conscious Awareness: Aims - To show the independent streams of conscious awareness possessed by each hemisphere and to show how each hemisphere has its own memories. Procedures - It had two visual fields. Left is what we can see on our right, right is what we can see on our right. Information from the left visual field goes to the right hemisphere. Information from the right visual field goes to the left hemisphere. They were given visual tasks and stimuli and tactile tasks. Results - Participants would recognize the stimuli if it was presented again to the same visual field, but if it was presented to a different one from before, they would claim to never have seen it. Objects placed in the right hand could be described in speech or writing, if the same objects were placed in the left hand participants couldn't recognize them. C...

Psychology 9-1 GCSE - 4.1.2 - Understand the lateralisation of function in the hemispheres, including: a) Asymmetrical function - Ellegood et al found that 'autistic' mice showed more symmetry between the left and right hemispheres of the cerebellum when compared to controls without mutations in the autism genes. Interestingly, the 'autistic' mice showed more asymmetry between the left and right hemispheres of the cerebellum. A wide range of studies have found that cerebellum size and functional connectivity is correlated with autism-related functions. Such as emotion, regulation and attention. b) Role of the left hemispheres - c) Role of the right hemispheres - Brain hemispheres and their functions d) Role of the corpus callosum - The corpus callosum consists of about 200 million axons that interconnect the two hemispheres. The primary function of the corpus callosum is to intergrate motor, sensory ...
