Test Retest Reliability

The visuospatial working memory plays a crucial role in the occupational performance of children including daily living and academic achievement. Unfortunately, relevant visuospatial working memory tests in the occupational therapy setting are lacking. Therefore, it is of clinical interest to develop new assessment tools in this area. The present study is aimed at summarizing the development of the visuospatial working memory assessment (VWMA) and assessing its psychometric properties. The results revealed that the score of item-objective congruence index (IOC) was 1.0 in overall items of assessment. The Cronbach alpha test confirmed that the internal consistency of VWMA showed good reliability in both types of the assessment, with the total score of computerized tests being .88 and the tabletop tests being .81. The computerized test was found to have excellent test-retest reliability with intraclass correlation coefficient (ICC) values ranging from .88 to .99. The tabletop test was found to have a fair to good test-retest reliability with the ICC values ranging from .51 to .63. As regards construct validity, the results revealed that the tasks in the computerized test identified a significant difference between the control group, normal children, and children with attention deficit/hyperactivity disorder (ADHD) group. The exception to this was the N-back task in which the independent sample t-test of computerized test ranged from 1.61 to 6.23. The results of the tabletop test revealed a significant difference between normal children and the children in the ADHD group over all tasks in which the independent sample t-test ranged from 3.05 to 8.40. In conclusion, good psychometric properties established as regards content validity, internal consistency, test-retest reliability, and construct validity provide evidence to support the position that the new VWMA is appropriate for children.

Related Potentials

This study is to investigate the Event-Related Potentials (ERP) from the background of Electroencephalograph (EEG) signal for working memory retention by using visual stimuli. The proposed analysis of ERP signal is to predict the performance of working memory retention for various frequency bands such as gamma, beta, alpha, theta and delta. This study is intended to process the EEG data into ERP data and analyze the ERP signal based on power spectrum density. This method is applied to data of normal children with age between 7 to 12 years old. Result showed that alpha power band increases during working memory retention towards visual stimuli compared to the other frequency band. 9 years old has the highest amplitude alpha power compared to the other group of age. Therefore, the alpha power band at the prefrontal cortex will be used for the next analysis of the working memory retention.

The Subject

A procedure for assessing children's recall of lexical items in the presence of a competing language task is described. The Competing Language Processing Task was designed to reflect the dynamic processes carried out in working memory during language comprehension and production by requiring that the subject hold words in temporary storage while analyzing and responding as true or false to statements. The development of the procedure is described and results of testing of 68 normal children ages 6, 8, 10, and 12 years are presented.

Use Of Knowledge

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.
