Video : The Selective Attention Test

“75-second video, by the psychologists Daniel Simons and Christopher Chabris, that shows six male and female students, in black or white T-shirts, passing basketballs to one another. The observer is asked to count the number of passes. About 45 seconds in, a person in a gorilla suit walks onscreen. She strolls between passers to the center of the screen, faces the camera, beats

In the article “Divided Attention”, author David Glenn presents the problem of multitasking and the inefficiencies it causes to students and average day people, arguing that multitasking and the overconfidence that goes with it limits the abilities of the students without them realizing it. The author is able to successfully argue his point by using studies ran by credible sources as evidence to support his claims and by being able to connect to his intended audience by making it easier for the reader to understand more complex topics in humorous ways.

In early observation of change blindness was made in 19th century when the film was edited and introduced. The editor came to realize that those watching it were not noticing the changed background (Norman, 2006). This made Williams James to become the first person to mention the lack of ability to detect the changes according to principles of psychology.

Change blindness occurs when the observer does not noticed any changes in their visual field.

From liking, to posting, to tweeting, internet fads spread in a matter of minutes. Soon enough, this attention-grabbing media is seen all over the internet and sometimes even makes its way into the books. “Gorillas in Our Midst” is an experiment done by a student professor and a graduate student that caught the attention of millions. Eventually, their findings inspired them to write a book, The Invisible Gorilla by Christopher Chabris and Daniel Simons. Chabris and Simons made a daring decision bringing their internet sensation to the publishing world. The purpose of writing this book was not just another explanation about the experiment. On the contrary, it is about the outcome and the discoveries made when comparing the results. It is about

Snyder and Posner’s study demonstrates that the use of resources inhibits other detectors. In their experiment, there were three conditions. In each one a warning signal appeared, prior to a pair of letters. The participants’ identified whether the pairs of letters were the same or different, as quickly as possible. For example, AA may appear. In the neutral condition, the signal was a +. In the primed condition, the signal was an A, for example. In the mislead condition the signal was an H, for example. The results of the study demonstrated that accuracy rates for all groups were high; however, the reaction time of participants differed. The mislead condition had the slowest reaction times, meaning they took the longest to be identified as the same or different (Posner & Snyder, 1975). This is because the wrong detectors were primed; thus inhibiting the correct detectors. Therefore, inattentional blindness occurs because the wrong detectors were primed, and the right detectors were inhibited, because the attentional and perceptual systems have a limited capacity.

Each trial begins with the presentation of a fixation cross in the center of the screen, visible for 500 milliseconds. The fixation cross is removed and immediately followed by the word and color stimulus; this

In the abstract the authors Daniel. J. Simmons and Daniel. T. Levin, document that the aim of the study was to determine the detection of change blindness for objects in still images and motion pictures, but their focus was to use people in the real world. In the abstract it is pointed out that the research was divided into two similar experiments only changing specific details in which the surrounding objects, such as; clothing, accessories and their general approach to the randomly selected subjects were changed or modified slightly. They would then continue by asking the participants whether or not they noticed the swap. If yes, they would follow up with asking about what tipped them off to the change and if no, they would retort to explaining what had just occurred by explaining the experiment.

Auditory selective attention modulates the cortical responses. Because of the corticofugal feedback from the auditory cortex to the brainstem level, the brainstem responses are affected by higher order mechanisms. Auditory selective attention increases selectivity and shifts the responses to the target sound. In this study in order to evaluate selectivity at the brainstem level during auditory selective attention, the cross-phasogram method was used. The responses were obtained in 15 normal hearing subjects. In this study, the cross-phasogram method was applied to the brainstem responses to the diotically-presented /ba/ and /da/ stimuli. Then it was applied to the brainstem responses to the dichotically-presented /ba/ and /da/ stimuli while

In 1935, John Ridley Stroop conducted an experiment at George Peabody College for teachers in the United States. Stroop used 70 college undergraduates as subject in his experiment, he compared times for reading names of colours and naming colours themselves. The aim was to determine if the colour of the word affected the ability to read it. In the experiment, there was three different conditions. In the first condition participants were asked to read words as quickly as possible whereas participants had to name the ink colour in which each word were printed as quickly as possible in second condition. In a third condition (the incongruent condition), participants had to name the ink colour in which each word was printed, but in this condition the words themselves were colour names. For example, the word ‘GREEN’ was presented in the colour orange and you were required to read this colour instead of the word itself. Stroop found that the participants were much slower at naming the ink colours when the stimuli were themselves colours as (third condition), indicating that a possible explanation for the Stroop effect is that people quickly and automatically process the meaning of the word.

The video was not that interesting because there was way too much going on in this video for me to get immersed. There are seven people all reacting in a panicked state at the same time and it is very overwhelming. It also is tiring because of the angle of the camera. We are all stuck in the middle of this table of giants as they pass on a bag of chips. The last problem

Eight years ago, in 2007, Cynthia Stafford was a 53-year-old software account executive living in California. She had a good life, but she imagined it could be so much better.

The gorilla was sad. so he started to move a bit more when he started to move people started to pile up more the

Another thing that really made me pay attention was the 911 phone call. I don’t think this was supposed to be such a big impact in the video but it was for me. The phone call was about an attack on a girl and she had called 911 for help. Being that she spoke another language, she needed translation (which is where I think it comes in handy with this video). Usually 911 translation operators don’t get these kinds of calls often. Most are questions about what we might think are “easy.” So this was kind of a shock. The phone call

The video starts off talking about a man who had a stroke and he is cognitively functioning well, but does not have use of his left upper extremity. They are trying to help him regain strength in his left hand by not letting him use his right hand. The key to help regain strength in the extremity that is not strong is to keep repeating exercises. You have to keep using the limb to help your brain revert back to how it was before it was affected. Another topic that the video talks about is how age affects mental performance, as you age you become slower with processing information and recalling less information. Physical activity and the other part is genetics have a big part on how fast the brain ages. The video also goes on to talk about parkinson's
