![]() ![]() The empty string is the identity element of the concatenation operation. The empty string has several properties: 0. a set of strings) that contains no strings, not even the empty string. The conclusion of the study was the MLD students couldn’t finish the tasks with high loaded working memory demand, but they were capable to finish some simple cognitive tasks such as short-term memory task, which meant that the counter interference and attention control abilities deficit was the core deficit in the MLD. The empty string should not be confused with the empty language, which is a formal language (i.e. (4) The developmental trend of memory span among the junior school students was no significant. E-Prime was used to create a platform for viewing these pictures on a computerized. (3) The regression analysis indicated that the backward digit span task which measured the digit working memory can better predict math achievement than the other two tasks which measured the short-term memory and reading working memory. the State Trait Anxiety Inventory (Form Y-1), Backwards Digit Span. The results of the study showed: (1) there was no significant difference between two groups in word series task (t=-1.59, p>.05), but significant difference between two groups in reading span tasks (t=-2.38, p.05) and backward digit span task (r=.05, p>.05). Each participant spent 30 minutes finishing the experiments with the guide of psychological graduate students. The stimuli of the forward and backward digit-span task were recorded in e-prime in order to make sure that the presentation duration and time between digit. The reading span task was designed on the computer by E-prime software, while the other two tasks were oral tests. The study designed the three experiments such as the word series task to measure short-term memory, reading span task to measure phonological working memory, and backward digit span task to measure digit working memory. There are 103 students participating the study, with 49 MLD students and 54 students who are good at math (with average age is 12.57-year-old). This goes on until the person can not longer repeat. If the person can repeat the sequence, the a longer sequence is presented. The basic idea of this task is this: A person is presented with a sequence of two digits. The criteria for defining the MLD or math learning disorder of this study is: the math score was lower than 20% of the total score, with normal IQ, and without the obvious organic deficit, emotional disorder and learning motivation disorder. The digit span task is an absolute classic for anyone interested in short term memory. The study was designed to find out whether the MLD students have deficit on short-term memory span or the working memory span. Recent Presentations Content Topics Updated Contents Featured Contents. Now there emerges a leading paradigm for carrying out research on MLD from the viewpoint of information processing. Collection of Digit span backwards slideshows. Math learning disability (MLD) is an important area of learning disability, accounting for large percentage of students in the middle school. This study tested the alternative hypotheses of Weinberg et al. The study was supposed to discover the cognitive processing mechanism of MLD. ![]()
