Long-term memory

nature of working memory (Baddeley 2000; Repovs & Baddeley 2006). The concept of working memory was first introduced in a paper by Baddeley & Hitch (1974). Following on from this, Baddeley (1986, 1990, 1992) proposed that the main neural network that forms working memory includes the phonological loop, the visuospatial sketch pad and the central executive. From his research, Baddeley concluded that, under certain conditions, subjects are able to carry out two tasks simultaneously as long as the…

Alzheimer’s disease is an affliction that many families and individuals all over the world have to endure. As the individual slowly loses their memory and their ability to recognize themselves and others, they succumb to the disease soon after. Elderly people are most often associated with this disease, but a significant population under the age of 40 has shown symptoms of this disease. The good news is that people, especially young people, can take precautionary measures to avoid being…

called a memory. Memories are the contents that a person can recall; whether it be something that happened when they were young, or remembering the sequence to a number pattern. A memory is the recalling of past events in life and remembering what has been learned. However, memories can be distorted. Memories may not always be accurate; a person can create false memories. While memories are not always precise, it does not mean that a person has altered their memories on purpose. Memories can…

Neuroplasticity changes in children are a common observation since children are still developing and growing. However, changes due to musical effects have been observed to take place across a life span. Adolescents (teenage years between 12 and 19) brain plasticity have been shown to be affected through musical training, even though typical plasticity changes are less likely to occur as you get older (Tierney, et al., 2015). Changes in plasticity can even be observed in adults who begin musical…

Early visual experience is essential for the maturation of visual functions. For example, behavioral studies have demonstrated that visual acuity is low at the time of eye opening and visual experience is indispensable for its developmental improvement (Maurer et al., 1999; Prusky et al., 2000; Kang et al., 2013). Visual cortical neurons selectively respond with a higher rate of action potentials to particular features of visual stimuli (Hubel, 1982), which is considered to be a fundamental…

Suggestibility, as it pertains to memory, is a person’s unknown tendency to incorporate incorrect or misleading information into his or her own personal recollection of an event. Some contest that suggestion is a subset of misattribution, but this is not this case. Misattribution can occur without the presence of overt suggestion; this is not the case for suggestion. This finding places suggestion and its effects in a distinct class of its own. While the power of suggestion can be hard to…

After watching the videos supplied, there are valuable lessons and techniques that are learned about questioning eye witnesses. Learning about the specific questions to ask an eye witness can be a curtail asset to an investigation. When someone witnesses a crime for the fist time, it can be shocking on that person. What they have seen and what they believe they saw can be totally different. In the interview stage with that witness, I learned that is is sometimes important to being with open…

Even though many research findings have found that age-related changes do not differ too much between DPOAES and TEOAES, I would use DPOAEs to test the adult population because of other factors, such as comfort of presentation level, frequency specific information, and more manual control options for the examiner. First, DPOAEs are presented at a moderate intensity level (70dB) compared to TEOAEs which are presented at a higher presentation level (78-80dB). Furthermore, to check for test-rest…

Mrs. Bell is a pleasant lady of 71 years old in extended leave, diagnosed with schizophrenia, hypertension, tremor and asthma. Client was referred by Dr. Kevin Wong from CRESST on February 16, 2017 for a cognitive assessment due to difficulty with memory skills. Dr. Wijeyesinghe also referred on February 1 for independent living skills assessment. Client provided informed consented to complete the evaluation process. Methods of Assessment 1. Standardized Mini-Mental State Examination (SMMSE)…

episodic memory (EM) – a contribution in which researchers have recently made efforts to delineate. Here I will evaluate the notion that frontal lobes contribute to EM, and suggest reasons as to how it might do this. Lesion studies We can look at lesion studies to assess the contribution of the frontal lobes to EM. Unlike cued-recall and recognition tasks (which offer cues to motivate retrieval), free-recall tasks require participants to recruit tactical processing to search for memory items…
