To what extent is it true that the brain is a sophisticated information processor? The human brain is the most important part of the nervous system. The brain together with the spinal cord constitutes the central nervous system and together they control all important functions of the body, such as motor functions, speech, vision, hearing and even involuntary functions such as breathing. Many of these functions are localized to a specific area of ​​the brain. The brain is divided into four lobes; the frontal, parietal, temporal, and occipital lobes, which are specialized to perform their different roles. The cortex is divided into two hemispheres; the left hemisphere is associated with motor control, speech and language functions, and logic; while the right hemisphere is linked to spatial perception and creativity. Communication in the brain occurs via neurons that transmit electrical impulses to other neurons via neural conduction (Wickens, 2009). They are connected by synapses which are small spaces between two nerve cells. There are approximately one billion neurons in the brain (Wickens, 2009), which means there are even more synapses. Synapses allow electrical impulses to pass from neuron to neuron as chemical messages in the form of neurotransmitters, since electrical messages cannot cross the synapse. Cognitivism was developed in the 1960s to help explain what behaviorism and the biological perspective could not. It aims to discover how conscious thought processes can influence behaviors. The theory compares the processes of the mind to the way a computer processes information. The modularity of theory of mind was mentioned by Jerry Fodor in his 1983 book "Modularity of Mind". It suggests that the mind is composed... in the center of a paper... spread out on the screen. However, the brain is not as fast as a computer at completing tasks that involve calculations or retrieving information from stores. However, it is capable of understanding emotions and storing data through depth of processing. It can encode semantically, which requires no rehearsal and allows memories to be easily retrieved without cues. Works Cited Baddeley, A. (2000).
