Disjunctive Reaction Time as it Relates to Complexity Level
The reaction time for subject with increase complexity is the focus of this study. The ten respondents were randomly selected on the campus of University Wisconsin at Milwaukee. Ten subjects reaction time was evaluated with a computer simulation program using one, two, or four choice trails, which lasted forty to sixty minutes. The data were analyzed using t test and ANOVA. The t test showed no significance as far as practice effects were concerned, but inferences can be made. Also the ANOVA showed a significant difference with reaction time as it relates to complexity. I found that as the level of complexity increase so does the reaction time.
Disjunctive Reaction Time Measure as it relates to Complexity of Task
This study was conducted to prove that reaction time increases as the level of complexity increases. Disjunctive reaction time was measured to eliminate subject reacting too early to the stimulus. Also make the tack more complicated and for subject to uses discrimination before responding to stimulus. Postman and Egan (1949) defines disjunctive reaction time as "two or more different stimuli are presented in random order…the subject is instructed to react to one but not to the other stimuli"(p 240). Rikli and Busch (1986) defined reaction time "as the latency from the onset of the visual stimulus to the depression of the microswitch"(p 646). Although a joystick was used to respond to the visual stimulus the same principle applies. For the purposes of this study both definition of reaction time were incorporated to facilitate proper measurement.

Relative to the normative sample, Ay’Yahri was less able to differentiate targets from non-targets. She made more omission errors. She made more perseverative errors. Ay’Yahri responded more slowly and displayed less consistency in response speed. She displayed more of a reduction in response speed at longer enter-stimulus intervals.

There will be men and women within the study, along with various races, including Caucasians, Hispanics, African Americans, Native Americans, and Asians. More women may participate in the study because women tend to retire earlier than men do. With the approval from three separate retirement communities, a flyer will be passed out to all of the residents among these communities about the study with further contact information. There will be 100 randomly selected participants from a compiled list of all of the residents who voluntarily decided to participate. These participants will come from Westminster Village, Digby Place, and Rosewalk Village, retirement communities within Lafayette, Indiana. I will include a fairly large and diverse sample of randomly selected older adults for a better representation of the general
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.

Fatigue, decreased mobility and impaired balance from the rheumatoid and osteoarthritis pain also increases the risk of falls (Stanmore et al., 2013). Age related changes such as sarcopenia causes muscle tone and strength to decrease, especially in the lower limbs and as a result, balance and gait become impaired (Culross, 2008). These factors significantly influence the risk of falls and also affect the ability to carry out daily activities therefore, with a physiotherapists assistance, the nurse could introduce a personalised exercise regime to enhance muscle tone and strength (Culross, 2008). According to Neuberger et al (1997), exercise lessens fatigue and improves muscle tone and balance in older people. Recommending an exercise programme for Mrs Jones that incorporates strength training exercises and aerobics, could potentially improve muscle tone and strength and as a result improve mobility, balance and lessen the risk of falls (Bird, Pittaway, Cuisick, Rattray & Ahuja, 2013). The nurse could also suggest safety precautions such as advising Mrs Jones to use a mobility aid (Gooberman-Hill & Ebrahim,
This study was conducted to determine the validity of the mobility subscale of the Braden scale. The subscale of mobility is defined as the patients ability to change and control body positions. The research was conducted in a veteran hospital, and participants ranged in age from 45-95 years. The tools that were used were the Braden scale and actigraphy which measures movement. It was placed on the patient’s non-dominant ankle in order to observe the larger movements of the patient. The researcher defined each score in relation to movement. They hypothesized that the increase in movement would cause an increase in score of the mobility subscale. As predicted, the mobility subscale scores increased as movement increased.
