Reaction time test Clause Samples

Reaction time test. Participants will be assessed on measures of simple and complex reaction time using a computerised test (programmed on SuperLab software by DMU). For the simple reaction time test, participants will be presented with a stimuli on a laptop screen (an asterix) and will be asked to press the space bar on the keyboard as quickly as the stimuli is presented. Data will be converted into elapsed time in milliseconds. For the complex reaction time test, testing higher order cognitive functions, participants will be asked to only respond when the letter ‘p’ is presented on the screen, not when the letter ‘d’, a distractor stimuli is presented. The tests take around 13 minutes to administer and will be based on those described by ▇▇▇▇▇▇ et al. [20] a full description of the tasks is quoted from the original paper in full below: "For the first ‘simple’ vigilance task, 110 asterisks would sequentially appear on the screen on the same location but with variable and random time intervals of between 1 and 10 s. Prior to the task, there was a brief training session of five targets, allowing the subjects to get acquainted with the task and the screen layout. Subjects were instructed to press the left of the two mouse buttons with their dominant hand as quickly as possible whenever they saw the target. They were told that the task had a duration of approximately 13 min and were asked to maintain their concentration as well as they could throughout the task. In the second task, the ‘complex’ vigilance task, either the target letter ‘p’ or the distracter letter ‘d’ would appear in the middle of the screen. The stimuli were drawn randomly from a list of 10 targets and 10 distracters without replacement, such that the maximum (though very unlikely) number of targets or non-targets appearing consecutively would be 10. The time intervals between successive stimuli changed randomly between 0.5 and 5 s. This ensured that the average interval between targets, the number of targets and the duration of the task would be the same as for the ‘simple’ vigilance task. The target and distracter letters ‘p’ and ‘d’ were chosen because the shape and size of the letters were the same, whereas they differed only in their orientation. There was a brief training session of 10 stimuli (five targets) preceding the task. Subjects were instructed to respond as accurately and as quickly as possible to the targets while ignoring the distracters. A total of 220 stimuli were presented on the screen, of ...

Reaction time test. The healthy elderly control group norm for lapses on the proposed reaction time test is 8.2 (SD = 2.6). Following DOREMI, we would expect values to fall within 1 SD of this healthy range >5.6. For false positives on the reaction time test (control mean =1.9, SD= 0.15) we would expect average false positives to fall with 1 SD of this healthy range <1.75. To ensure reliability of the reaction time computer programmed test, and provide norms for reaction time in milliseconds for people with MCI and healthy controls, the test will be administered to a group of people with MCI and a group of healthy controls (the reference groups from WP5) prior to the intervention. We will take the mean and standard deviation from the healthy control group trial and use this to inform a clinically significant outcome value. Following DOREMI, we would expect participants to fall within 1 standard deviation of the healthy control group reaction time mean. Scores used as cut-off and the final score represent a value adjusted according to age and education, they are not the rough test outcome. For each participant, however, the final test score will be put in relation with the possible health worsening. Age-related frailty is always a factor that must be taken into account within projects dealing with the elderly.

  • Random Testing Notwithstanding any provisions of the Collective Agreement or any special agreements appended thereto, section 4.6 of the Canadian Model will not be applied by agreement. If applied to a worker dispatched by the Union, it will be applied or deemed to be applied unilaterally by the Employer. The Union retains the right to grieve the legality of any imposition of random testing in accordance with the Grievance Procedure set out in this Collective Agreement.

  • Random Drug Testing All employees covered by this Agreement shall be subject to random drug testing in accordance with Appendix D.

  • Drug Testing (A) The state and the PBA agree to drug testing of employees in accordance with section 112.0455, F.S., the Drug-Free Workplace Act. (B) All classes covered by this Agreement are designated special risk classes for drug testing purposes. Special risk means employees who are required as a condition of employment to be certified under Chapter 633 or Chapter 943, F.S. (C) An employee shall have the right to grieve any disciplinary action taken under section 112.0455, the Drug-Free Workplace Act, subject to the limitations on the grievability of disciplinary actions in Article 10. If an employee is not disciplined but is denied a demotion, reassignment, or promotion as a result of a positive confirmed drug test, the employee shall have the right to grieve such action in accordance with Article 6.

  • Meter Testing Company shall provide at least twenty-four (24) hours' notice to Seller prior to any test it may perform on the revenue meters or metering equipment. Seller shall have the right to have a representative present during each such test. Seller may request, and Company shall perform, if requested, tests in addition to the every fifth-year test and Seller shall pay the cost of such tests. Company may, in its sole discretion, perform tests in addition to the fifth year test and Company shall pay the cost of such tests. If any of the revenue meters or metering equipment is found to be inaccurate at any time, as determined by testing in accordance with this Section 10.2 (Meter Testing), Company shall promptly cause such equipment to be made accurate, and the period of inaccuracy, as well as an estimate for correct meter readings, shall be determined in accordance with Section 10.3 (Corrections).

  • Performance Testing (a) All performance tests of the Project, including any Initial Performance Test required in Section 2 of Appendix VIII, will be performed in accordance with the test procedures set forth in Appendix VIII (“Performance Test”), including additional procedures and protocols related to Performance Testing as mutually agreed between Buyer and Seller (“Test Procedures”). Seller shall bear all costs and receive all revenues, if applicable, associated with all Performance Tests. (b) After the Initial Delivery Date and during the Delivery Term, Buyer will have the right to conduct a Performance Test (“Buyer Performance Test”) no more than once a calendar year to demonstrate whether the Project is capable of delivering the Distribution Services at the Contract Capacity. Within 30 calendar days following a Buyer Performance Test, Seller will have the right to retest the Project with a Performance Test (“Seller Retest”). For the avoidance of doubt, the results of any Seller Retest will supersede the results of the preceding Buyer Performance Test. (i) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at or above ninety-nine percent (99%) of the Initial Contract Capacity, the Contract Capacity will remain the Initial Contract Capacity; (ii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is capable of delivering Distribution Services at more than or equal to eighty-five (85%) of the Initial Contract Capacity, but less than ninety-nine percent (99%) of the Initial Contract Capacity (“Testing Band”), the Contract Capacity will be automatically adjusted (upwards or downwards) to the capacity commensurate with the amount of Distribution Services the Project delivered during the Performance Test within the Testing Band. (iii) If a Buyer Performance Test or, if a corresponding Seller Retest has occurred, a Seller Retest demonstrates the Project is not capable of delivering Distribution Services of at least eighty-five percent (85%) of the Initial Contract Capacity, an Event of Default shall occur in accordance with Section 7.1(a)(viii).
