memorable words boosts children’s associative memory

Compute false alarm rates and memory accuracy corrected for false alarm rates

Do memorable stimuli free up resources for encoding other things?

Are more memorable words encoded more holistically, improving memory also for related information?

Subsetting on all of the words that were remembered: people are more likely to remember details associated with highly memorable words than non memorable words

df[mem_acc == 1 & fam_rem_ec==1, .(num_details_recalled = sum_mem), by = .(Age_cat, memorability_median_cat)]%>%

For the top 10% of memorable words, children’s memory performance for details is similar to that of adults

df[mem_acc==1 & fam_rem_ec == 1, .(sum_mem = mean(sum_mem)), by = .(Sub, Age_cat, top10)]%>%
  ggplot(aes(Age_cat, sum_mem, color = as.factor(top10))) +

Do memorable words impact close by words?

Are kids performance up to adults for top 50% of memorable words?
