Fwd: My type (1) questions on my design of the experiment

Prof. Tsai

I got my pics modified, removed the status bar and anything unnecessary.
But I still have questions about drawing ROIs
I got a sample PDF for you to make clear of my doubts.
I am not sure if I shall give dozens of ROI color blocks according to my need. Or shall I use only one color to draw my ROIs.
Yet if I only use one ROI color, it would be useless to draw ROI.

My research question focus on the parsing of the sentences, esp. on the predicates. I assume the participants would quickly get the keys of parsing a sentences after I put on the mnemonic devices for them.

I also have to simplify the condition: setting up this as a t-test, assuming the participants have the same habits and ability on reading.
Due to this issue, I can't get ROI map of index color for research if I don't have these questions clarified.

So can I meet you up tomorrow morning?
I guess it'd be alright if I use the people in the lab as participants?
Since some of our classmates may not be able to be in the lab tomorrow morning.
My hands still hurt badly. I can hardly type. 
But let's keep in touch

Thank you for the clarification.
I am not sure if I shall use ANOVA or tTest in this case. This is my methodological question.

My hands and fingers are wounded due to overuse of computer in the library work.
Maybe I shall try voice recognition or sending a recording voice file on writing a letter next time.

Hi, prof. Tsai

I got some problems for my experiment design. I am not sure if this belongs to t-test or something else.  
I am still learning statics from udacity https://www.udacity.com/course/statistics--st095 
I wish to be familiar with these methods

My questions can be classified into two types:  technical and methodological

Let me describe my technical problems first. 
There're four of them in total.
  1. ppt ratio
  2. How about the background color? (Mine is like grey mixed with a little bit of yellow)
  3. shall I remove the bookmark and the status bar?
  4. And after all, is ROI the suitable tool to detect such a subtle process on syntax parsing / clause parsing? 

On Thursday you mentioned the way we use to make ROI map in powerpoint/ keynote
But I found that our monitor is wide-screen with different ratio (16:9 or 16:10)
If we export the ppt file to PDF, the background (and the foreground pics )would be in different ration.
We should decide the ratio of the ppt before we export it to PDF.
I suppose we shall fix it to 4:3 ? Even if ti's exported to PDF and display on a wide-screen monitor like iMac, it will remain the ration 4:3 instead of being stretched.

Since we need to do color indexing, the color of the background shall be taken into account.
(I just knew this on this Thursday. )
But I guess it's ok to assign the background a color number since What we're interested in are only the ROIs.
To make the background color not white is quite important, this will make the reader blink less or read better on the monitor.
So I think I would keep the background, is that ok, prof. Tsai? 
For ROI files, the background has to be black with the index number 0. For the passage to be read, you are right about the white color that would makes the readers' eyes uncomfortable.
We use grey (120,120,120) for the background color when presenting the text.

Finally for the ROIs:
I am looking for the parsing pattern change in the help of mnemonic devices in sentences. I suppose the readers will find that the main idea in each sentence lies after the verb, the so called "depiction part" of a sentence. These m-devices are there to help them figure this out. 
I assume they will speed up after a few pages of training. They will go directly to the red underline parts of the sentences, which are located at the rear part of sentences (after the main verbs).

If we put ROIs on the main verbs, can we detect their eye movement to the rear part of main verbs? 
What shall I do to do such detection? 
You may simply make another ROI to include the critical word(s) at the rear part of the sentence. Therefore, there is one ROI for the main verb and the other for the clause.

As for the additional elements: 
I am not sure if the bar at the bottom of the pic will effect the reader. Maybe I should remove it, or just let the reader know that there's an unimportant bar so they won't look at it at all. The pictures are captured from my cellphone (as an E-reader) so it has a bar there.  
I found you notice Zuzana's page number at the bottom right. So I think I might have the same issue.
