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…
An issue with the localisation of brain function is generalisability. E. This is because the pattern of activation observed in response to various behaviours can vary from individual to individual. E. For example, Harasty et al (1987) found that women have proportionally larger Broca’s and Wernicke’s areas than men. L. This is problematic because it suggests that there are gender differences in the localisation of the brain which affects the generalisability of the theory. P. An issue with location as an explanation of brain function is the use of case study evidence E. For example, that of Phineas Gage who damaged his frontal lobe in an accident and consequently suffered from impaired motor control. E. This was a unique case which means that it would be hard to replicate the situation – i.e. the chances of someone having exactly the same damage as Gage’s would be unlikely ever to occur. L. Therefore, the case study evidence localisation relies on fails to actually provide solid evidence due to lack of
