For both OSPAN and RSPAN, the dependent variable is the total number of words/letters correctly recalled.

Digit span cog lab demo series#

Individuals are tested on three series of each length (12 in total). In both the OSPAN and the RSPAN, each series consists of a random number of strings between two and five. At the end of the series, they write down the sequence of letters. In the RSPAN, individuals read the sentence aloud and are asked to verify whether the sentence makes sense. The RSPAN involves reading a series of sentence–letter strings (e.g., “Walking in the park is a very enjoyable activity.” (Does this make sense?) M). At the end of the series, they write down the sequence of words. Individuals are presented with one equation–word string at a time (e.g., (3 × 4) − 2 = 10? CAT) on a computer and asked to verify aloud whether the equation is correct (hence the question mark). In the OSPAN task, the participants must solve a series of arithmetic equations while attempting to remember a list of unrelated words. Operation span (OSPAN) ( Turner & Engle, 1989) and reading span (RSPAN) ( Daneman & Carpenter, 1980) tests require updating and monitoring of working memory representations.

They come about in the mid-seventies as part of the APA public ethics code for researchers dealing with human subjects.

Who is the IRB, you ask? IRB stands for Institutional Review Board.

The IRB doesn't require that you do this for running yourselves, but we do this so that you get an idea of what writing an informed-consent form is like.

Contact information for the subject should they want any additional information about the experiment.

That the subject may leave the session at any time.

That there are no risks to the participant.

what participation will include (sitting at the computer, whispering color names to yourself as you see them on a screen, etc.).

why it's being run (as part of a class assignment in experimental psych).

what, generally speaking, it is looking at.

what you are calling it/what it is called.

The consent form should be a very brief paragraph that tells the subject:.

Now you'll need to write an informed-consent form for those subjects to sign.

you can do this by entering in each column of information into Matlab as a vector (e.g., 'x = ' and 'Enter'), and taking the mean of that vector ('mean(x)' and 'Enter').

At the end, calculate the mean of each condition/column.

make a column for each condition - 3 columns, 10 data points in eachĮx: Color No color time1 time2 time3 time4.

Record your time for each run of the experiment (two decimal places in is fine).

Don't do them all in a row - go back and forth between the conditions you've chosen.

Once you have chosen your 3 conditions, run yourselves 10 times on each condition.

I should compare the Black & White condition to the same condition in color.' (here's a thinker: which condition(s) would that be?)

A kind of silly example: 'I bet that the presence of color serves as a distraction to subjects, and slows them down.

Note: This is important, since you'll have to explain your selection in your paper!

Before you run yourselves, you must pick 3 conditions (e.g., Same, Different, Missing Letters) that somehow logically relate to each other.
