Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Twin and genomic studies provide robust evidence that short-term memory and working memory capacity are moderately heritable traits influenced by genetic factors.

The analysis

The retrieved literature includes direct empirical evidence from twin studies and genomic structural models (such as papers [3] and [10]) demonstrating that working memory and executive functions are significantly influenced by genetic factors. There are no papers directly refuting the genetic heritability of short-term memory.

This twin study demonstrates significant genetic contributions to working memory capacity, showing that heritability accounts for a substantial portion of the trait's variability.
