Later research on short-term memory and working memory revealed that memory span is not a constant even when measured in a number of chunks. The number of chunks a human can recall immediately after presentation depends on the category of chunks used (e.g., span is around seven for digits, around six for letters, and around five for words), and even on features of the chunks within a category.
Grammatical abbreviations are generally written in full or small caps to visually distinguish them from the translations of lexical words. For instance, capital or small-cap PAST (frequently abbreviated to PST) glosses a grammatical past-tense morpheme, while lower-case 'past' would be a literal translation of a word with that meaning.

As such, Richard J.C. Brown (who proposed the prefixes adopted for 10 ±27 and 10 ±30) has proposed a reintroduction of compound prefixes (e.g. kiloquetta-for 10 33) if a driver for prefixes at such scales ever materialises, with a restriction that the last prefix must always be quetta-or quecto-. This usage has not been approved by the BIPM ...
Anhedonia is a diverse array of deficits in hedonic function, including reduced motivation or ability to experience pleasure. [1] While earlier definitions emphasized the inability to experience pleasure, anhedonia is currently used by researchers to refer to reduced motivation, reduced anticipatory pleasure (wanting), reduced consummatory pleasure (liking), and deficits in reinforcement learning.
