Abstract
The idea of mental imagery has always been a controversial subject in the field of psychology. Many psychologists have argued that such a concept is impossible to measure because it can not be directly observed. Though they are right about this, it is not impossible to measure how quickly mental rotations of images are processed in our brains. Subjects in this experiment were presented two shapes simultaneously, via computer screen, and asked to make judgement, as quickly as possible, as to whether the two shapes presented were the same or mirror images. Two different shapes were used in this experiment, each given as often as the other. During each trial one shape remained stationary and the other was rotated with varying amounts of 0, 60, 120, and 180 degrees. As the angle of rotation increased reaction times were calculated to see if this had any baring on the speed of the reaction. As predicted, reaction times increased along with angular disparity.
Rotation of Mental Images: Measured by Reaction Times
There are a limited number of ways to discover and understand how the human mind works and reacts to things. One can not sit and directly observe the brain and eye working together (James, Schneider & Rodgers, 1994). The concept behind mental rotation of images tries to do this by measuring reaction times as the angular disparity of an object increases. Thus, demonstrating the time it takes for the eye and brain to make a connection when presented with a stimulus. Though our experiment was solely limited to calculating reaction times to mental rotations of images, Wohlschlager and Wohlschlager (1998) took this concept one step further to see if mental object rotation and manual object rotation shared a common thought process in our brain.
Wohlschlager & Wohlschlager (1998) based their ideas for this study on a theory, most impressively demonstrated by Cooper (1976), stating that the resemblance of mental rotation to external physical rotation, calls for a mental process that mimics external physical rotation. However, it is pointed out that there is a principal difference between motion perception and mental rotation. Whereas motion perception is a rather automatic process, mental rotation is strategic and shares some characteristics with voluntary actions (Wohlschlager & Wohlschlager, 1998).

... 4, and 3 & 4, we see no statistical significance at all. The difference in rotational degrees was not as large between these groups.
Another aspect of the results that I would like to point out is that our experiment only used 10 subjects, who were not randomly picked. Only 20 subjects were used in the experiment conducted by Desrocher, smith & Taylor (1995). I don’t feel that these numbers of subjects (20 and 10) are enough to have conclusive results. In order to get an accurate sample of the population more participants should have been used in both experiments. This one fact may have been the reason why part of the results of Desrocher, smith & Taylor (1995) were not concurrent with other findings.
Although the objectives of the two experiments I discussed were different, result were the same regardless as to what the differences might have been. In all experiment including the one I did, results were concurrent. Findings supported the hypothesis that was set forth: As angular rotation increased, reaction time will also increase. Thus, showing reaction times do serve as an appropriate method for analyzing how quickly the brain reacts to mental rotations of images.
Rock n’ roll gave people the voice they did not have in the early years. As the genre of music became more wide spread, people actually began to speak out. Altschuler touches on the exploration of how the rock n' roll culture roughly integrated with replaced and conflicted with preceding cultural values. Many of these values were very touch topics. Besides black civil rights, sexuality were one of the most sensitive t...
Some may choose to do something and change for the positive. Others may not, and conflict can have a negative influence. There was a good amount of conflict throughout this book. One example of this conflict is when T.Ray and Lily fight over Lily’s mother leaving. Lily believes her mother left because of T.Ray, while T.Ray says she left because of Lily. They get into an argument and the following day she decides to leave. This choice and reaction from the conflict brings Lily to a more supportive environment with August, May, and June. Another conflict within the story was when Rosaleen was taken to prison. This showed a different, protective side of Lily that we had not seen yet. This conflict showed her strength and from this point on she started to grow and decided to be stronger. Throughout the story, Lily experiences a lot of conflict. Each of these experiences forced her to make decisions and many of her
In closing, the undoubtable influence of music, more specifically of Rock ‘n’ Roll on American society is responsible for a number of changes to the status quo. These range from sexual liberation and racial desegregation all culminating with other influences to create an intergenerational identity. Despite the desperate attempts of older generations to smother these influences, these changes ultimately shaped the years that followed, molding the country into what it is today. Along the way these changes as well as individual involvement in them has also eased the lives of many through empowerment and a feeling of community and purpose. Despite a lull and renewal Rock ‘n’ Roll continues to serve as an agent of influence and change in today’s youth culture and continues to burn in the heart of past generations of loyal fans.
Although its initial peak of success occurred in 1956, rock and roll had been developing since 1951. The introduction of the 45 rpm disc, transistor radio, and television; and finally, its lively, upbeat sound all contributed to the success of rock and roll(Peterson, 102- 104). The “baby boomer” generation after the Second World War, was a major influence on the success of rock and roll. Unlike their parents, this g...
Parole, as defined by the Bureau of Justice Statistics, “refers to criminal offenders who are conditionally released from prison to serve the remaining portion of their sentence in the community” (Terms & Definitions: Corrections, 2014). On the other hand, the Bureau of Justice Statistics states that “probation refers to adult offenders whom courts place on supervision in the community through a probation agency, generally in lieu of incarceration” (Terms & Definitions: Corrections, 2014). Regardless of their similarities and/or differences, both of these serve as a valuable alternative to incarceration. The impact of community correction programs such as probation and parole minimize recidivism without the need of rehabilitation or reintegration

Following many researches, in 1971 at McGill University failed to find a statistical difference to confirm his theory. Many came to the conclusion that the theory is not true.(Cepuk, 2014)
The researchers had the participants’ complete three parts of the experiment: the learning phase, the TNT phase and the final memory phase. In the learning phase, the participants were presented forty eight object image pairs and asked to recall them. The participants were asked to learn a behavioral response for each item. The participants were then shown one of the forty eight objects and asked to press a key indicating left or right depending on the strength of the associated picture. After this, participants were then shown the correct related picture for two seconds as response. ...
Although considered the day Rock ‘n’ Roll was born, many other events in American history have given foundation to this much loved idea. Rock ‘n’ Roll is much more than just music, rather it is the movement which underlines cultural imperialism. Rock had been promoting a culture of comfort and freedom from social constraints as well. Although the style of ‘Rock music’ is easily adaptable into many different sounds, it is still thoroughly identified by its definingly amplified rhythm. The sudden worldwide popularity of rock and roll resulted in an unparalleled social impact. Rock ‘n’ Roll influenced lifestyles, fashion, attitudes, and language in a way few other social developments have equaled. The social impact is so large that rock stars are worshipped worldwide. In its early years, many adults condemned the style of music, placing a stigma on its name, and forbid their children from listening and following its ways. Many considered Rock ‘n’ Roll culture as a bad influence to all people, but as the genre aged and the now not-so-young crowds had matured, Rock was respected and
As with the mental map experiments, the fact that reaction time depends directly on the degree of rotation has been taken as evidence that we solve the...
Constructivism represents a paradigm shift form education based on cognitive theories. This concept assumes that learners construct their own knowledge on the basis of interaction with their environment. (Gagnon & Collay, 200?) The role of the teacher as a constructor of the learning experience to ensure authentic curriculum and assessment which is responsive to the skills, needs and experiences of the learner, within established curriculum framework and with the reference to the achievement of literacy, numeracy, retention and attainment of outcomes. Krause, Bochner and Duchesne (p.157) comment that “as learners interact with their environment, they link information learned through experience to previous knowledge, and so construct new understandings and knowledge.” Constructivism then inturn encourages Teachers and Learning Managers to recognise the value of prior knowledge and experiences that each child brings with them into the classroom, and help them (the students) build on their understandings of the world by providing appropriate learning experience plans.
The widely popular research on mirror neurons and various applications of the research findings began with an important, but unexpected finding in the brains of macaque monkeys. The original studies did not intend to look at mirror neurons and in fact the existence of mirror neurons was found by accident. Neuroscientist Giacomo Rizzolatti and his colleagues found a group of cells that fired whenever a monkey prepared to act on a stimulus as well as when it watched another monkey act on the stimulus (Winerman, 2005). For example, the monkeys showed a similar pattern of activation when they were performing a simple motor action like grasping a peanut and when they watched another monkey perform the same action (Winerman, 2005). In other words, monkey see, monkey fire -- monkey do, monkey fire. This grouping of cells was called "mirror neurons." The ...
Our entire lives have been shaped by the events happening around us. Along with us many factors in our day to day lives have evolved too, including musical genre. One such genre is rock. Rock is a genre for the youth, by the youth, it has evolved to stay with the times and stand up for what’s right. In this essay I will prove why rock is a good example to show how genre has been defined, maintained, constructed and negotiated through the past 60-70 years since the very first Proto Rock song came out.
Constructivism is a method that says students learn by building their schema by adding to their prior knowledge by the use of scaffolding (Rhinehart Neas). Because the students are basically teaching themselves new information, the teacher is there mainly for support and guidance for the students.
Among many teaching styles and learning theories, there is one that is becoming more popular, the constructivist theory. The constructivist theory focuses on the way a person learns, a constructivist believes that the person will learn better when he/she is actively engaged. The person acts or views objects and events in their environment, in the process, this person then understands and learns from the object or events(P. Johnson, 2004). When we encounter a certain experience in our life, we think back to other things that have occurred in our life and use that to tackle this experience. In a lot of cases, we are creators of our own knowledge. In a classroom, the constructivist theory encourages more hands-on assignments or real-world situations, such as, experiments in science and math real-world problem solving. A constructivist teacher constantly checks up on the student, asking them to reflect what they are learning from this activity. The teacher should be keeping track on how they approached similar situations and help them build on that. The students can actually learning how to learn in a well-planned classroom. Many people look at this learning style as a spiral, the student is constantly learning from each new experience and their ideas become more complex and develop stronger abilities to integrate this information(P. Johnson, 2004). An example of a constructivist classroom would be, the student is in science class and everyone is asking questions, although the teacher knows the answer, instead of just giving it to them, she attempts to get the students to think through their knowledge and try to come up with a logical answer. A problem with this method of learning is that people believe that it is excusing the role of...
