Aphantasia And Mental Perceptions

Improved Essays
Helen Thomson of the BBC reported on aphantasia, which is a condition where a person is unable to form mental imagery, or imagine things. Aphantasia fits into cognitive neuroscience, because it related to people’s mental perceptions. Cognition plays a role, but more in a lack of there of sense because people with aphantasia have the inability to creat images with their mind. In the article, Thomson reports about a person named Philip, who had no idea that people had the ability to create mental images. He believed that everyone did not have an imagination, and if he was told to imagine something he thought that they were just using a figure of speech. To provide information on aphantasia, Thomson interviewed Adam Zeman and Joel Pearson. Zeman …show more content…
His main area of research is cognitive neuroscience, which includes visual perception, which most likely led him to research aphantasia and people’s perceptions. The research conducted was basic research, looking into manipulating people’s imagination. This was done by using binocular rivalry, which was also able measure mental images. Pearson also looked into brain mechanisms and how they function when a person is using their imagination to create mental images. Pearson’s research found that when the visual cortex is less active, than their imagination and mental images will be stronger. This led to further research based on the correlation between the visual cortex and the strength of the images. The technique Pearson and his team used was non-invasive brain stimulation and expanded on mental images to PTSD and anxiety, in hopes that decreasing mental imagery associated with it. Animals were not tested, but humans were, which is helpful due to the ability to receive self-reports from case studies. Pearson and his team first went into research aphantasia by trying to pinpoint any correlations, which is when they discovered the correlations with the visual cortex. This led to further research that led to the hypothesis that manipulating a person’s mental image can ease PTSD and related mental imagery. They also hypothesized that manipulating mental images can enhance a person’s

    By understanding the functionality of the brain allows for psychologists to explore new ideas in understanding behaviorism and motivations of humans. They can learn these aspects by examining the way people learn behaviors. Therefore studying these factors helps explore the way cognitive ability and unconscious function in order to work with one another. Combining these functions help an organism learn different behavioral and survival aspects in order to evolve and survive. Studies have been conducted to stimulate this connection by observing two different types of conditioning: classical conditioning developed by Ivan Pavlov and operant conditioning developed by B.F. Skinner.…

    The mental processes were the software and the nervous system was the hardware. Under this model cognitive psychologists focused on the functions rather than the content. During a controlled experiment researchers were able to observe “inputs” and “outputs” of the mental system. This led them to believe internal mechanisms must be the key to mental functioning. This field continues to be influential in the study of memory, perception, and consciousness.…

    Initially, I thought that the idea of a placebo was clever and safer process than taking drugs and medication. Regardless, reading more into the placebo is interesting to think of it being based on the person unaware of the sugar pills or false surgery being done. It is scary to think that there is a chance that you may not get better might be because the proper medication was given and a doctor chose to prescribe a placebo instead. It is always interesting to see both sides of an issue in order to better understand the true effect that this process would have on patients. In the end, the placebo effect is an interesting psychological concept that has proven to be both effective and hazardous.…

    It is a form of psychotherapy that is intended to improve and understand one’s self. The final approach to anxiety disorder is cognitive therapy. Cognitive neuroscience is the mechanisms of the brain and nervous system when involved in memory, thinking, and other cognitive processes. Jake’s anxiety comes from the way he thinks. Scientist under this field use things like magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and positron emission tomography (PET) to record the activity of the brain.…

    However, Watson makes it clear that he feels psychology has failed to project itself as such due to the false idea that its array of facts are “conscious phenomena” (Kimble and Thompson, 1994) and that introspection is the only straightforward confirmation of these facts. He notes that its theoretical goal is the prediction and control of behavior. He continues to discuss introspection and how it does not form any essential portion of its methods, “nor is the scientific value of its…

    Model Of Consciousness

    In order to scientifically and systematically give explanation to consciousness, it must be seen as an objective occurrence and consciousness currently is not considered an objective state according to most neuroscientists (Searle, 2000). In fact, Searle (2000) infers that consciousness has been an avoided topic of research for the most part because it is different from other biological phenomenon in which the subjective first-person process of consciousness cannot be removed during research testing. This should indicate to the majority of the public that neuroscience cannot truly explain consciousness because of the fact that it cannot be accurately measured. It seems impossible to measure something that cannot be visibly seen by the researcher and expect the results to have high validity. As explained previously, the subjective nature of consciousness produces participant answers to researcher questions that are first-person oriented.…

    Primarily, John Locke questions Descartes theory of innate ideas. Innate ideas, in Descartes eyes, cannot be learned by experience, but rather they are inbeded in everyone’s minds. These ideas include, God and mathamatics. When speakng about these ideas, Locke states, “But yet I take the liberty to say that these propositions are so far from having an universal assent, that there are a great part of mankind to whom they are not so much as known”. Locke claimes that people are not born with these innate ideas, but instead people start off with a blank slate, and they form ideas from sense perception and from reflection upon those senses.…
