The text "The Perfect Murder" by J. Archer describes the story of Carla, who wants to get rid of her abusive husband. Carla's behaviour towards problem-solving is complex and can be analysed in terms of different psychological theories and concepts. Firstly, it is evident that Carla has a strong motivation to solve her problem. According to Maslow's hierarchy of needs, human beings are motivated by a hierarchy of needs, with basic physiological needs like food and safety at the bottom. At the top of the hierarchy are self-actualization needs, such as achieving personal goals and fulfilling potential. Carla's desire to get rid of her abusive husband can be seen as an attempt to achieve safety, as well as to gain control over her life and fulfil her potential. Secondly, Carla's approach to problem-solving is characterized by planning and strategic thinking. This can be seen in her preparation for the murder, including researching poisons and creating an alibi. However, this also reflects her flawed thinking process. Carla's planning is based on the assumption that murder is the best solution to her problem, rather than seeking help or considering other options. This can be seen as an example of confirmation bias, where an individual focuses on information that confirms their pre-existing beliefs, rather than considering alternative perspectives. Thirdly, Carla's involvement with her lover demonstrates the concept of emotional intelligence. Emotional intelligence is the ability to regulate one's emotional responses and understand the emotions of others. Carla's lover is fond of her and is willing to help her, which makes her feel secure and understood. Carla's emotional intelligence allows her to manipulate her lover's emotions to achieve her goal more effectively. For instance, she uses her sexual attractiveness to keep her lover committed to the plan, and avoids showing any emotional attachment to him, which could increase the risk of discovery. In conclusion, Carla's behaviour towards problem-solving is driven by her motivation to achieve personal goals, strategic thinking and emotional intelligence. However, her flawed thinking processes may lead her to an ineffective solution like murder. Analyzing Carla's behaviour in the context of psychological theories allows us to understand her motivations and thinking processes, and helps prevent individuals from following a similar path.
