What are some phenomena related to the functioning of phonological loop?

Phonological loop consists of a phonological store (holds information for few seconds) and articulatory rehearsal process (responsible for rehearsal). The different phenomena related to the functioning of phonological loop are similarity effect, the word length effect and articulatory suppression.

1.Phonological Similarity Effect: is the confusion of letters/words that sound similar and this happens when words are processed in the phonological store.
2.Word Length Effect: memory for lists of words is better for short words than for long words.
3.Articulatory Suppression: this is when a person repeats some kind of an irrelevant sound or counts backwards so that he/she is prevented from rehearsing items to be remembered.

The basic idea behind the phonological loop is that it allows us to repeat (rehearse) auditory information in our minds. There are three phenomena that are related to the functioning of the phonological loop- phonological similarity, word length and articulatory suppression.
The phonological similarity effect occurs when we confuse sounds that sound familiar. For example we confuse the letter F with S rather than with E because we rehearse it in our minds based on the sound not visual properties.
The second phenomenon, the word length effect, is based on the fact that it's easier to remember short words than long words. This is rather obvious but it's a good example of how the phonological loop functions. This effect occurs because it takes more time to repeat longer words in our phonological loop than shorter words(repetition in the loop happens in the same time it would repeating out loud). Since it takes longer we have less time to rehearse each word and in addition to this it takes longer to recall each of them. Because of these two things retention is worse for longer words.
Articulatory suppression occurs when the work of the phonological loops is disturbed. Participants are given an auditory element to remember and then are asked to repeat irrelevant sounds before recall. The repetition of the irrelevant sound makes the participant unable to rehearse the auditory element and therefore causes recall to be poor.
