Working memory in school-aged children: Exhibition intervals and distracters effects in Memonum computerized test

This study assessed visual working memory through Memonum computerized test in schoolchildren. The effects of three exposure times (1, 4 and 8 seconds) have been evaluated, and the presentation of a distractor on the mnemonic performance in the test Memonum in 72 children from a college in the metropolitan area of Bucaramanga, Colombia, aged between 8 and 11 in grades third, fourth and fifth grade. It has been found significant difference regarding the exposure time in the variables number of hits and successes accumulated, showing a better mnemonic performance in participants who took the test during 8 seconds compared to children who took the test during 1 second; in addition, the presence of a distractor showed a significant difference regarding the strengths and successes accumulated. Such distractor is considered a stimulus generator interference that disrupts the storage capacity of working memory in children. Additionally, a significant difference was found with respect to the use of mental rehearsal strategy, indicating that participants who took the test in 4 and 8 seconds, respectively, assigned higher scores than children who took the test in 1 second. A long exposure time to stimuli during Memonum test increases the holding capacity. Also, the use of a distractor affects the storage capacity and this, at the same time, increases the school progression due to the use of mnemonic strategies that children use to ensure the memory of the numerical series

The current study arose from previous studies made by McClelland (1972), Namam; Slevin (1993), Kuratko; Hornsby; Naffziger (1997), Hoeltgebaum; Kato (2002); Hoeltgebaum;Debastini (2003), Hoeltgebaum; Santos; Loesch (2003) and Hoeltgebaum; Santos (2003). Its objective is to understand the reasons that that lead an entrepreneur to open his ownbusiness, his degree of satisfaction and to perceive if there is a relation between entrepreneurial motivation and the performance of companies. In order to concretize the objective, a descriptive qualitative/quantitative research was realized, amounting to 88 questions of a closed type, statistically ordered. Data collection was achieved by means of a questionnaire divided into 4 parts. Once responses to the questionnaires were obtained, analysis was performed on them, using LHSTAT software. Among the principal results, it was evident in the analysis of the questionnaires that there were a variety of motivations for opening a new business present among the interviewed, with a small, distinct difference in the frequency of the responses. When the satisfaction of the respondents regarding the performance of the company was analyzed, it was perceived that the greatest satisfaction derived from gross and net profit margin and return on investment. Several interdependencies between motivation and satisfactionand performance were evident in the research, with three in particular being the strongest. It was decided to include a category regarding behavioral characteristics of entrepreneurs tothe objectives of the project in which, according to the interviewees, these have a strong entrepreneurial profile; results showed that all the characteristics are well developed. It wasconcluded that the intrinsic motivations are more evident in the entrepreneurs interviewed and that the greatest satisfaction among them lies in the area of gross and net profit margin andin return over investment. It was perceived that there are clear relationships between the motivation of entrepreneurs and satisfaction with the performance of companies.
