Catching Rulers and Reaction Times The reaction time of ten subjects was measured. The subjects were asked to catch a ruler ten times under five different conditions. The first condition measured the subject's simple reaction time. Each further condition added an additional stimulus and the reaction times were measured. There was a clear increase in reaction time with the addition of further stimulus, however the expected result of a steady increase in response time with the addition of each condition did not occur. The third condition displayed the highest response time where as the final condition displayed the second lowest (after condition 1). Assuming that no design problems in the experiment affected the results, it cannot be concluded that cognitive processes occur in separate order and do not overlap. Given the average reaction time of condition five was lower than condition three, some cognitive adaption may have occurred to lower the response time of the subjects or another reason may exist. One aspect not covered by the experiment, but important to the results was the error factor. Pre-guessing the experimenter caused a high rate of error, however it lowered the overall results. Why measure response times? As the world moves forward with technology, increasing pressure is placed upon humans to be quicker, be smarter and to operate more efficiently. As the population increases systems are being put in place to reduce incidences and accidents occurring. An example of this is a study conducted by Cameron, 1995 examining the influence of specific light colors, motor vehicle braking and the reaction time of the drivers to these specific clouds and conditions to avoid rear end collisions. Donders subtractive method holds that reaction times can be obtained by subtracting the simple reaction time; or subtracting type A from type B etc. (Cameron, 1995). Given this, it stands that the more stimulus provided (or thought processes required), the longer the response time of the subjects. This theory is tested in the measurement of ten responses to five test conditions. The trial provides preliminary information to participants and it is expected that reaction times will be shorter than if no information was supplied. (Rosenbaum, 1980.) Method Participants Ten participants were selected, four female and six male. Ages ranged from twenty-two to fifty three. All were fully able bodied and from English speaking backgrounds.
1.There will be two groups, the control and experimental groups. Each group will have the same amount of participants with equal numbers of boys and girls. The first group will be the control group(rest). The second group will be the experimental group(exercise).
Participants had to meet certain criteria. They set up an interview day with the first hour being the section of the workshop that contained personal results such as scores on lower body strength and problem solving. Next they attended three 30-minute sessions that gave them information on topics such as nutrition and stress management. There were a group of participants that participated in the actual interview. They were taken to a private room where they sat at a table. Questions were asked and the person being interviewed would respond with an answer. The interview started with questions such as how life was living with FM and then questions became more detailed such as how to maintain
The number of individuals in my targeted population is six. The genders of these six were 5 females and 1 male. The participants are within the age group of 15+. I intend to recruit my participants through finding people that I am regularly with. My participants will be interviewed personally.
We hypothesized that the more an image is rotated, the longer the reaction time will be because of the additional mental processes that must take place in order to correctly complete the object recognition. We further hypothesized that the angle will overall have a greater impact on the 2-dimensional pictures than the letters. Additionally, we hypothesized that the combination of both the object type and the angle together will affect reaction time more significantly overall.
Applicable populations: The assessment is designed to be utilized with individuals between the ages of 18-73 (SASSI, 2001).
...e up from the unconscious - from behind a locked door inside of our brain - but just because something is outside of awareness doesn't mean it's outside of control." (Gladwell, Blink: The Power of Thinking Without Thinking , 2005) While rapid cognition is a subconscious process that has been created within us throughout our lives, it is possible to increase that reaction time to allow for more analysis of the information we are given. Being able to do so can increase the effectiveness of a leader, and improve change management on any level of an organization.
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. ...
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...
The relation of automaticity and the brain can be seen by performing tasks and examining brain activity before and after automaticity training. Before the training of automaticity, the sections of the brain used when performing serial reaction time (SRT) tasks are an activation of a wide network of frontal and striatal regions, as well as parietal lobe (Poldrack et al. 2005). After the training of a...
Many factors can influence the results of testing this hypothesis. All variables have been controlled except for the variable gender. Both the male and female subjects are close in age (< two years difference), both are nonsmokers, both possess small body builds for their respective gender, and both have no debilitating medical conditions (e.g., asthma, diabetes, heart condition). Controlling these factors allowed for the testing of the hypothesis, which is focused strictly on gender.
The experiments were quite simple, in that there was a seemingly harmless task to be performed, and the participants were instructed to choose the estimation of the lengths of a line when compared to two ...

Although, there was no field called cognitive psychology during the 19th century, Donders and Ebbinghaus were referred to as cognitive psychologists because both of their experiments dealt with the studying of the mind. Donder’s experiment focuses on a person’s Reaction-time in order
No matter what someone is doing they are relying on assumptions, allowing them to react faster and more consistently. All of the assumptions our mind makes stem from the overarching assumption that the world around us is fairly predictable and reactions to similar situations will elicit similar results. There are basic assumptions such as, objects have consistent mass, small objects have less mass than large ones, and objects fall down, which allow us to move around and manipulate objects in a predictable manner. An example of an automatic assumption that our brain makes is location tagging where we bind features based on their physical location, meaning if the features orange and round are in the same location, then then they are assumed to be on the same object which is both orange and round. An example of how this assumption can be incorrect can ...
