Working memory

Beside repeated questioning, another procedure that eyewitness most likely will have to go through is face identification. There has been a debate whether it is more accurate to identify suspect through photograph or in person. A study by Megreya and Burton examined the effect of method used in identification process (2008). The study consists of two experiments; experiment 1 assessed how accurate people can remember unfamiliar face immediately after the presence. The study involved 92…

1. This experiment compared the spatial selective attention between “neurologically normal young adults” and split-brain subjects by measuring response times when presented unilateral and bilateral visual arrays. 2. The purpose for this experiment was to gather information about spatial selective attention, and to investigate whether “an independent focus of attention is deployed by each surgically separated hemisphere in a visual search task, such that bilateral stimulus arrays can be scanned…

Proactive Inhibition shows that Short-Term Memory and Long-Term Memory are not as different as once believed. – Author’s Goal: The author wanted to isolate components within the primary memory and secondary memory to decipher if either were susceptible to Proactive Inhibition. – Hypotheses: If there were more than seven obstacles then the recall is believed to be from the secondary memory, but if less than seven obstacles recall would be from the primary memory. • Experiment 1 (5 pts.) –…

In an article written by Alan Kingstone, Chris Friesen, and Michael Gazzaniga they are discussing a study about gaze reflection and reflexive joint attention. They used two similar people to conduct multiple experiments to test out their hypothesis. In the article, Reflexive Joint Attention Depends on Lateralized Cortical Connections, their hypothesis was that the reflexive attention in response to gaze direction correlates with the hemisphere specialized for processing faces. The people used…

Recently Bournemouth University's Doctor Sarah Bates and Anna Bobak have found that people called "super-recognizers" outperformed control participants in a face matching test. The two researchers believe that super-recognizers could play a large role in security settings and jobs such as border control. Super-recognizers have exceptional face recognition skills, just as the name implies. Matching faces with old documents, or spotting a specific face in a crowd can be difficult and error-filled…

My average adjacent length was about 4.5% less than the correct length, so it concludes that the illusion had a small impact on my perception of line. 2A: How is this illusion related to depth perception? When we see the two lines to be at different distance, our brain try to figure out that which is near to our vision by showing the visible distance. So the line which form near edge of an exterior corner, we think that this line looks shorter…

Magician’s exploit the limitations of attentional and perceptual systems. They manipulate a process of selective attention; priming, resulting in inattentional blindness. Inattentional blindness describes the inability of a person to notice an unexpected object that is fully visible (Carpenter, 2001). Priming is an alteration in the identification or production of an item due to prior exposure (Tulving & Schacter, 1990). There are many different types of priming. This essay examines selective…

The potentials of neuroimaging technologies are vast. During his lecture on the principles of neuroimaging data, Dr. Lindquist highlighted “emerging applications” of functional magnetic resonance imaging (fMRI) as a means to predict not only health status, but also human behavior (Lindquist, 2016). But, does this mean that neuroimaging has the ability to predict or even influence the success of political campaigns? Neuropolitics, an arising field, posits that it can. In “Neuropolitics, Where…

Changes in body systems and organs with age are highly variable and may be results of disease, which in turn may be affected by lifestyle. Most body systems generally continue to function fairly well, but the heart becomes more susceptible to disease. Reserve capacity declines. Although the brain changes with age, the changes are usually modest. They include loss or shrinkage of nerve cells and a general slowing of responses. However, the brain also seems able to grow new neurons and build new…

In this study, we selected to study power of alpha frequency due to the accumulated data from previous studies that alpha power changes reflect cognitive processes related to attention and semantic memory (Krause et al., 2008). Moreover, Higashima et al. (2007) reported that event-related alpha attenuation may not be a unitary cognitive phenomenon, desynchronization of the lower alpha activity is topographically widespread on the entire scalp and…
