Memory and Biology
Memory and Biology There are many events in a person’s life that leave an impression or may “change” a person’s perspective or path. From birth to death the mind is recording lessons and adding to the infinite storage space known as memory. Classical conditioning Lives are filled with many lessons; some of these are learned through classical conditioning, operant conditioning, and behavioral observation. A simple example of classical conditioning would be whenever walking into the kitchen the feeling of hunger begins to present itself. The unconditioned stimulus is the kitchen; by itself the kitchen provides no stimulus. The unconditioned response is hunger, hunger is an involuntary response. The conditioned stimulus is the food that is prepared and eaten while in the kitchen. The conditioned response is becoming hungry each time the individual walks into the kitchen. This is a simple example of how classical conditioning works. Other examples could be a loved one wears a certain perfume, each time you smell that scent you smile and feel happy. This is also classical conditioning Operant conditioning Another way of learning life’s many lessons is through operant conditioning. In operant conditioning there is a positive or a negative reinforcement. If an individual spends the night singing Karaoke and fellow patrons clap and cheer, this is a positive reinforcement. If they boo and recommend getting off the stage, than this is a negative reinforcement. Singing is the control behavior, the consequence or reinforcement is the response of the crowd, depending on the response of the fans, positive cheering, or negative jeering this is a clear example of operant conditioning. The individual will either return again and again for an evening of idled worship or never again in fear of humiliation. In operant conditioning the individual is making an aware choice to stimuli whereas in classic

    Severe emotional trauma causes lasting changes in the ventromedial prefrontal cortex region of the brain that is responsible for regulating emotional responses triggered by the amygdala. Specifically, this region regulates negative emotions like fear that occur when confronted with specific stimuli. PTSD patients show a marked decrease in the volume of ventromedial prefrontal cortex and the functional ability of this region. This explains why people suffering from PTSD tend to exhibit fear, anxiety, and extreme stress responses even when faced with stimuli not connected – or only remotely connected – to their experiences from the…

    First, Oehen et al. (2013) briefly outlined a current neurocircuitry model for PTSD. Oehen et al. (2013) stated that individuals with PTSD experience exaggerated and uncontrolled fear responses in the amygdala, as a result of the individual experiencing trauma specific stimuli. In addition, Oehen et al. (2013) stated there is a deficient…

    Post-traumatic stress disorder was first introduced into the Diagnostic and Statistical Manual of Mental Disorders in 1980. Although the PTSD criteria was revised twice previously, research in the field of traumatic stress brought to light a number of concerns regarding the conceptualization of trauma and PTSD. These concerns motivated a revision process for the recently published DSM-5 that culminated in a number of significant changes to the PTSD criteria. The most notable of these changes included moving PTSD out of the anxiety disorders and into a new diagnostic category named “Trauma and Stressor-related Disorders.” As in adults, PTSD in children and adolescents requires the presence of re-experiencing, avoidance and numbing, and arousal…

    A Review of PTSD

    Post traumatic stress disorder (PTSD) is an anxiety based disorder that can be developed after witnessing or experiencing a dangerous event associated with serious personal injury or death. PTSD is a relatively new term that was first described in 1980 in the Diagnostic and Statistical Manual of Mental Disorders vol. 3 (DSM III) for what had widely been known as “shell shock”. The term shell shock was coined during World War I and was used to describe the actions and behaviors of soldiers who expressed fear, panic, an inability to walk, talk, fight, or make rational decisions during or after battle. This term developed into PTSD as time went on due to the fact that other traumatic events outside of warfare seemed to cause similar effects in the general public. It was found that not only war and battle related trauma exposure caused PTSD but other traumatic events such as sexual assault, serious or life threatening injury, natural disasters, and intimate contact with danger could also spur the onset of PTSD (American Psychiatric Association, 1980). The bridging of a disorder only seen in combat veterans to members of the general public has sparked great interest in the fields of clinical neuroscience and psychology that has led to further research of the disorder. Due to this increased interest advances have been made in the understanding, identification, diagnosis, categorization and treatment of PTSD.…

    Not all individuals who are exposed to a traumatic event develop PTSD; researches hypothesized that biological and environmental factors contribute simultaneously to the development of PTSD. In order to better understand the disorder, this paper focuses on the possible risk and resilience factors of PTSD, its symptoms, its biological environmental contribution and types of treatment. In conclusion, the paper advocates the interrelated nature of the disorder and suggests the next steps needed in research to better prevent and overcome the disorder.…

    Operant conditioning, although similar to classical conditioning, has many different aspects. Operant conditioning is another behavioral training technique that was coined by B.F Skinner. Operant conditioning basically states that behavior is influenced by the consequences that follow. Seems simple, right? That’s because it is. Operant conditioning applies to many aspects of our everyday life even without our knowledge. For instance, we’re in class and a teacher asks a question. You answer it and happen to get it right. The teacher then gives you 5 points extra credit as a reward. That’s going to make you want to answer more questions correctly, right? That’s exactly what operant conditioning is based upon. This helps us better understand human behavior because it tells us…

    When a memory of a past experience is not activated for days or months, forgetting tends to occur. Yet it is erroneous to think that memories simply fade over time—the steps involved are far more complex. In seeking to understand forgetting in the context of memory, such auxiliary phenomena as differences in the rates of forgetting for different kinds of information also must be taken into account.…
