The left-brain interpreter attempts to rationalize, reason and generalize new information it receives in order to relate the past to the present. [4] Left-brain interpretation is a case of the lateralization of brain function that applies to "explanation generation" rather than other lateralized activities. [5]
One of the experiments carried out by Gazzaniga involved a split-brain male patient sitting in front of a computer screen while having words and images presented on either side of the screen, and the visual stimuli would go to either the right or left visual field, and thus the left or right brain, respectively.
The English word "left" comes from the Anglo-Saxon word lyft which means "weak" or "useless". Similarly, the French word for left, gauche, is also used to mean "awkward" or "tactless", and sinistra, the Latin word from which the English word "sinister" was derived, means "left". Similarly, in many cultures the word for "right" also means "correct".
a) The right hemisphere has more control over emotion than left hemisphere. [n 2] b) The right hemisphere is dominant in emotional expression in a similar way that the left hemisphere is dominant in language. c) The right hemisphere is dominant in the perception of facial expression, body posture, and prosody.
The brain activity is tied to one thing, like a specific object or task. The goal is to figure out how the brain represents specific things (like seeing a face or recognizing a word) when you're actively engaging with something. For example, with fMRI scans, researchers can track brain activity while people look at different objects or images.
This isn’t your typical quiz filled with random facts—this is a logic, common sense, and outside-the-box thinking challenge, inspired by questions from The 1% Club TV game show.
The idea first began circulating in the neuroscience community after some split-brain patients exhibited alien hand syndrome (AHS), which led some scientists to believe that there must be two separate consciousnesses within the brain's left and right hemispheres in competition with one another once the corpus callosum is severed.
Convergent thinking is a term coined by Joy Paul Guilford as the opposite of divergent thinking. It generally means the ability to give the "correct" answer to questions that do not require novel ideas, for instance on standardized multiple-choice tests for intelligence .
