Assertion (A) : Lesions of the amyqdala decrease people’s emotional responses.
Reason (R) : Memory of frightening event is poor in people with damaged amyqdala
Codes :
Assertion (A) states that lesions of the amygdala decrease people’s emotional responses. The amygdala is a key brain region involved in processing emotions, especially fear and threat detection. Research shows that damage to the amygdala often leads to a reduced ability to experience or express emotions, particularly negative ones like fear. Therefore, Assertion (A) is considered true.
Reason (R) states that memory of frightening events is poor in people with damaged amygdala. The amygdala plays a critical role in the formation and consolidation of emotional memories, particularly those related to fear. Damage to this area can impair the ability to create lasting memories of aversive or frightening experiences. Thus, Reason (R) is also considered true.
The question asks if Reason (R) correctly explains Assertion (A).
Therefore, both statements are true, but the poor memory is not the correct explanation for the decreased emotional response.
Based on the analysis, both Assertion (A) and Reason (R) are factually correct statements regarding the function of the amygdala. However, the reason (impaired fear memory) does not directly explain the assertion (decreased emotional responses). The decreased emotional response is a consequence of impaired emotional processing, while impaired memory is another consequence related to memory consolidation.
Correct Option: Both (A) and (R) are true, but (R) is not the correct explanation of (A).
