Beck's (1976) traditional model proposes unidirectional effects from cognitive constructs on depressive symptoms (Pössel, 2011). He identified three mechanisms (Beck and Alford, 2009) that he deemed responsible for depression. The cognitive triad has three forms of negative thinking: negative thoughts about the self, the world and the future (Hodgson, 2000). The interaction between these components interfere with usual cognitive processing. This results in the individual becoming consumed with negative beliefs and thoughts. The second mechanism is a set of beliefs and expectations about yourself that are negative and pessimistic. These negative self-schemas leave the individual predisposed to depression, and therefore someone who has developed…show more content…
They results showed that those women considered to have been high in cognitive vulnerability were most likely to experience post-natal depression. These cognitions can be seen before depression develops, suggesting that Becks theory may be right about cognition causing depression. This research demonstrates that many people suffering from abnormalities exhibit faulty thought patterns. Therefore due to supporting research cognitive explanations appear to offer a valid account of…show more content…
Before these investigations, Scientists commonly took a holistic view over language neurobiology and thought that all areas of the brain were involved in the processing of thought and action. Hemispheres of the brain and the cerebral cortex: The brain is divided into two symmetrical halves called the left and right hemispheres. Some of our physical and psychological functions are dominated by a particular hemisphere (lateralisation). As a general rule activity on the right-hand side of the body is controlled by the left hemisphere and activity on the left-hand side of the body is controlled by right hemisphere of the brain. The outer layer of each of the hemispheres is called the cerebral cortex. It covers the inside of the brain, it is around 3mm thick. This is what separates us from other animals as this is much more developed in humans. The cortex appears grey (hence the term ‘grey matter’) due to the location of cell bodies. visual cortex. This means that damage to the right visual cortex can cause blindness in parts of the left visual field. Finally the temporal lobes house the auditory area. This deals with speech-based information. Damage here my result in hearing loss; the more damage the more the loss of
