Declarative memory Declarative memory requires conscious recallin that some conscious process must call back the information.
Physiology[ edit ] When a stressful situation is encountered, stress hormones are released into the blood stream. Adrenaline is released by the adrenal glands to begin the response in the body.
Adrenaline acts as a catalyst for the fight-or-flight response which is a response of the sympathetic nervous system to encourage the body to react to the apparent stressor. This response causes an increase in heart-rate, blood pressure, and accelerated breathing.
The kidneys release glucoseproviding energy to combat or flee the stressor. Cortisol Adrenocorticotropic hormone axis[ edit ] When a receptor within the body senses a stressor, a signal is sent to the anterior hypothalamus. At the reception of the signal, corticotrophin-releasing factor CRF acts on the anterior pituitary.
The anterior pituitary in turn releases adrenocorticotropic hormone ACTH. These substances are the main factors responsible for the stress response in humans.
Cortisol for example stimulates the mobilization of free fatty acids and proteins and the breakdown of amino acidsand increases serum glucose level and blood pressure,  among other effects. As a result of cells retaining sodium and eliminating potassiumwater is retained and blood pressure is increased by increasing the blood volume.
Vasopressin axis[ edit ] A second physiological response in relation to stress occurs via the vasopressin axis. Vasopressinalso known as antidiuretic hormone ADHis synthesized[where, when and how? ADH has the greatest[greatest among what? Under normal circumstances, ADH will regulate the blood pressure and increase or decrease the blood volume when needed.
Vasopressin is released and causes a static increase in blood pressure. This increase in blood pressure under stressful conditions ensures that muscles receive the oxygen that they need to be active and respond accordingly. Thyroxine axis[ edit ] The third physiological response results in the release of thyrotropic hormone-release factor TRF [Where, when and how?
Chronic stress[ edit ] Chronic stress is a stressor that is ongoing for a long period of time. When chronic stress is experienced, our body is in a state of continuous physiological arousal.
When chronic stress is perceived, however, the body is in a continuous state of fight-or-flight response and never reaches a state of homeostasis.
The physiological effects of chronic stress can negatively affect memory and learning. In the RAWM, rats are taught the place of a platform that is placed below the surface of the water.
They must recall this later to discover the platform to exit the water. It was found that the rats exposed to chronic psychosocial stress could not learn to adapt to new situations and environments, and had impaired memory on the RAWM. The participants were between 65 and 97 years old.
Any patient that suffered from signs or conditions that would affect their cortisol level or cognitive functioning was exempt from participating. However, participants with greater cortisol levels showed signs of slower decline.
Neither of these effects held for the non-cognitively-impaired group. There are mixed findings on the effects of acute stress on memory.
One view is that acute stress can impair memory, while others believe that acute stress can actually enhance memory. First, the context in which the stress is being perceived must match the context of the information or material being encoded.
In some cases neutral stimuli tend to be remembered, while emotionally charged salient stimuli tend to be forgotten.
In other cases the opposite effect is obtained. When a person is under stress, the sympathetic system will shift to a constantly tonically active state. To further study how acute stress affect memory formation, a study would appropriate to add examine.
All participants were right-handed and had no history of a head injury, or of any medication that could affect a person central nervous system or endocrine system. All of the volunteers participated in two different sessions a month apart.
The study consisted on the participants viewing movie clips and pictures that belonged to two different categories: The participants had to memorize then rate each movie clip or picture by pressing a button with their right hand.
They were also monitored in other areas such as their heart rate, pupil diameter, and stress measures by collection of saliva throughout the experiment.
The participants mood was assessed by using the Positive and Negative Affect Schedule.The researchers found that Japanese participants were more likely to evaluate the emotions of those surrounding the central person when trying to judge their emotion than Western participants did (Masuda et al, ).
7 This indicates the influence of a collectivist culture in taking into account the emotions of the whole group, rather than focussing on an individual's emotional state.
The effect of teaching methods on cognitive achievement in biology studying December · Procedia - Social and Behavioral Sciences The purpose of this paper is to determine the effects of usage of sequential teaching method on the academic achievement and retention level of students.
Test your short-term memory and learn memory improvement techniques. There are several techniques that you can use to improve your memory. Try the following exercise to see how well you normally remember things, then move onto the next section to learn one of the skills of retention.
