The biological approach uses many different methods to investigate human behaviour and these are classified as invasive and non-invasive which in other terms means that they involve the introduction of instruments into the body or that they don’t involve the introductions of instruments into …show more content…
The idea is that the more active a neuron is the more glucose it will require as energy.” This makes sure that that the scanners’ computing software can generate a 3D image “of the different levels of radioactivity across the brain” and this also makes sure that areas of activity in the brain are highlighted and shows which areas are more active than others. Additionally, the use of brain scanning is not ethical because it does not require to be carried out invasively. Furthermore, PET scanning reduces the need to experiment on animals. However, it can be still be uncomfortable to participate in this activity because they are required to be in a scanner for a long period of time. Moreover, it is expensive for the procedure to be carried out because it needs advanced technology. Another non-invasive technique is the “recording of the brain’s electrical activity.” Here, electrodes are attached to various locations on the scalp and sophisticated technology then converts the electrode signals to …show more content…
Cognitive Psychology relates to developments, which can be from both past and the present, in the investigation of the memory process, verbal communication, discernment, the ability to solve problems and the way we think. Furthermore, cognitive psychology looks at the ways in which individuals behave in operations when they are given data or information that they have been given from different sources. “Cognitive Psychology revolves around the nation that if we want to know what makes people tick then we need to understand the internal processes of their mind.” Cognition simply means “knowing”. In other words, cognitive psychology refers to the study of human mental processes and their role in thinking, feeling, and behaving. Cognitive psychology focuses on the way humans process information, looking at how we treat information that comes in to the person (what behaviorists would call stimuli), and how this treatment leads to responses. In other words, they are interested in the variables that “mediate between stimulus/input and
