Meeting people like you.. I don't know whether it's inspiring or depressing hahaha
I need to manage my time better :S

I think it's a bit of both. I just get distracted so easily

What is the difference between short term memory and working memory?

[avcestudent]

Short term memory and working memory are just different names for the same thing. Short term memory (STM) is the term used in Atkinson-Shiffrin's multi-store model of memory, whereas working memory is the term used in Baddeley and Hitch's model. The term working memory just emphasises the fact that it is the part of memory where information is temporarily held and actively 'worked on' as we undertake our everyday tasks.

[Vermilliona]

The Oxford textbook says baddeley and hitch see "working memory as part of LTM, which includes the knowledge of facts and procedures that become activated in memory at any given time when brought into conscious awareness" but at the same time it doesn't really make sense, because in another part it refers to the interaction of working memory and LTM, thereby qualifying them as two different things?

How exactly do context and state dependent cues enhance memory? I know what the two are but i just can't seem to understand how being in the same context or state as the original experience help us remember what happened?

That's exactly what's confused me! I initially thought they were the same thing but I was given a table to fill in where short term and working memory were sorted into two different categories

This is the script given for our ERA:


Participants must be aged 13-18 years old and not a Psychology student.
You must test two separate participants. You can randomly pick one to be in the
Recognition group (Group 1)and one to be in the Recall group (group 2).
Script
1. Ask participant if they would be happy to take part in a memory study for your Y12
Psychology class. It will take aprox 5 min.
2. Read: “You will be given a list of nonsense syllables. You will have 4 minutes to
memories this list as best you can”
3. Present participants with list A and time them for 4 minutes.
4. After 4 minutes cover list A.
5. Group 1 is then given list B and asked to “please circle as many syllables you can
recognise from the original list”
Group 2 is then given a response sheet C and asked “please write down as many
items from the list as you can remember, they can be written in any order”
6. Participants are given as much time as the need.
7. After they are done thank them for their time and debrief them on the aim of the
study.
8. Score the lists and collate the results with your class.

Is it safe to say that:
Dv: Amount of time given to each participant
IV: prescence of the list of non syllables

[Paulrus]

i'd go with iv: whether the participants used recall or recognition as a measure of retention, and dv: the amount of nonsense syllables retained/remembered
i think where you're getting confused is you might be remembering the dv as 'the thing being measured', and so you went for amount of time because it's a numerical value. remember that an experiment is testing a relationship between variables - you want to see whether the independent variable seems to have an effect on the dependent variable.

you change the IV to see if it has any effect on the DV. the thing being changed between the groups is the measure of retention being used (i.e. recall or recognition), so that's your IV. and you'll notice that it asks you to 'score the lists' by counting how many nonsense syllables they retained. and bam, there's your DV!

hopefully that helped a bit, feel free to ask if you need anything cleared up

You are a god among men! If i could give you more up votes i would.
Thank you so much,I seem to always get confused with the iv and dv and research emthods in general.I will definitely seek you for any advice.

I'm confused a bit because people in my class said the dv was the scores.

no worries! research methods is the biggest pain in the arse in psych haha. feel free to inbox me if you ever need anything!

I'm confused a bit because people in my class said the dv was the scores.

the tests you're doing are measuring the amount of syllables they can retain, which is shown as their score on the test. like if on the first test they retained and wrote down 21 of the 30 syllables (or however many there were on the original list), their score for that test would be 21. so if you said 'score on the test' or 'amount of nonsense syllables retained', both should really be considered correct cos they're essentially the same thing. your teacher miiight be a bit pedantic though so it could be a good idea to check with them

[millie96]

could somebody help me rephrase this hypothesis?

That VCE students aged 16-18, whom are asked to free recall from a list of 15 words they were shown for 30 seconds, will recall a higher percentage letters from short term memory when they are chunked, compared to those letters that are not chunked.

I don't think you should talk about short term memory in your hypothesis because that's part of the discussion section. Maybe something more like:
VCE students aged 16-18 who are shown a list of 15 words for 30 seconds will be able to free recall more words that are chunked than words which are not chunked.

And I'm assuming this is a repeated-measures design and operationalised right?
