Attention versus memory in prefrontal cortex

Nicholas Carr 's argument is based on the work of scientist studying online reading, the memory and attention that our brains are very capable of. This experiment was the first one launched in 2008 by small and two…

Memory is a process of encoding, storing, and retrieving information. It is the total sum of who we are and what we know. It is also absolutely crucial in everything we do and affects how well we do it. A large variety of studies have already been conducted on memory and show that there are different types of memory. In their study, Luo and Craik (2008) looked at the effects of age on memory and found that aging contributes to increasing difficulty to complete complex memory tasks. There’s a…

subconscious mind and memory quite a bit. The hippocampus is the base of where memories are formed and stored. So, when subjects are given a list of words to remember, they are using that part of the brain to store is in their short-term memory. During a study at Stanford University, hypnotized subjects were first put in the emotional state of either happy or sad, and then had to learn a set of words while in that emotion (Bower). The results that were found deemed to be quite interesting. The…

are certain changes in gray and white matter densities, brain volume, as well as endocannabinoid concentrations. This creates aberrations in cognition and memory performance. Cannabinoid’s structures consist of a terpene joined to an alkyl-substituted resorcinol. The leading psychoactive component of cannabis is Delta-9-Tetrahydrocannabinol (THC). Cannabidiol (CBD) and cannabinol(CBN) are cannabinoids that make up cannabis (Perrine, 1996, p. 347-349). Gray and white matter are subsets of…

information gets in the way of when one is trying to recall older information. This new material interferes with remembering old information already stored in the long term memory (LTM). An example of this would be if an individual were to call his/her ex-girlfriend/boyfriend the new boyfriend/girlfriend’s name. This example shows that the recent name retroactively interferes with the previous name, which is evidently problematic for recall. b. A distorted or false memory is a contrived…

dynamic inter-relationship between genetic, brain, cognitive, emotional, and behavioral processes across the developmental lifespan [1].” Neurodevelopmental disorders are defined as a group of conditions caused by damage to the neurological development process which cause long term delays in development. These disorders normally begin in infancy, when development is most crucial, and remain fairly consistent throughout adulthood. Neurodevelopmental disorders include but are not limited to the…

psychiatrist and neuroscientist at the University of Pennsylvania, ran an experiment involving twenty-three healthy patients from the UPenn community and performed the Guilty Knowledge Test on them (Langleben et al., 2002). This lie-detection test seeks to interrogate participants through knowledge of the crime that would only be known by the criminal. By using four categories of cards as “Lie”, “Nontarget”, “Truth”, and “Control”, Langleben et al. suggests three areas of your brain are…

attention, and although they are good at helping to expand on some biological explanations, the scientific evidence found by other biological theories seems to outweigh that found by environmental explanations. Consequently, it seems that there is a constant struggle between biological factors versus environmental factors, when it could even be a mix of the two. However, on the other hand there are psychological explanations, which falls into a different category entirely. So, the other side of…
