Can somebody provide a standard test to measure ones working memory & short term memory I suffer from memory problem but find it difficult to undrstand whether it is more belief based or real, need a standard test to confirm.
It might be difficult to distinguish between belief-based and actual memory difficulties, especially in a self-administered test. The most objective measure would be a computerised assessment, e.g. the Automatic Working Memory Assessment, which contains measures of short-term and working memory in the verbal and spatial domain [1]. Some commonly used assessments of these constructs are [2]:

Verbal short-term memory: digit span, running span
Verbal working memory: backward digit span, n-back span
Spatial short-term memory: dot matrix, forward Corsi block task
Spatial working memory: backward Corsi block task
