Hi!

I am just getting started with the fMRi data analysis. Have very little programing experience. As there are few GUI based software packages available what package(s) is/are best for a newbie like me?

Thanks

HI!

I was wondering if it is possible and to a certain extent viable program a normal webcamera to be used as an eyetracker? This can be a great tool for those who may not have funds to procure a professional eyetracking hardware.

Also, are there any opensource softwares available that can do the abovementioned task?

Regards

Thanks

Rather than getting a study published in a journal can we publish that empirical study as a book chapter in a book???

Is it normal?

Hi!

I am working on a patient group that has mood and affect related changes. I want to know if there is a paradigm (cognitive task) that can see the effect of mood or affect on working memory performance?

Apart from ICSSR, DST, and UGC what are the other funding agencies (private or government) which can be approached. Apparently, the aforementioned funding agencies are very competitive.

Thanks

The study aims to find whether three types of depression (mild, moderate, severe) affects memory differently. Also, there will be a control group. Thus there are 4 groups.

There are three types of memory tests to assess three types of memory namely:

Long term memory

Working memory

Visual memory

For each of these memory functions three different tests have been administered with each test yielding a single score that. Thus we have 3 different DVs corresponding to each memories i.e., long term memory, working memory, visual memory.

Coming to the hypothesis I have 3 hypothesis. Whereby predictions are made regarding performance of each group on these 3 measures. So:

H1: severe group will perform poorly in comparison to other groups on visual, working memory and long term memory measures.

H2: Moderate group will perform poorly in comparison to mild group and the control group on long term memory measure.

H3: Mild group will perform poorly in comparison to the control group on measure of working memory.

Now in such a situation should I go for

MANOVA or ANOVA?

I get pretty confused when people say that I should use ANOVA as each ANOVA will be testing each hypothesis and thus chances of rejecting a true null hypothesis will not be their.

PS: I am assuming that my data is following the basic assumptions required to conduct both of these tests.

Thanks

I am looking for a valid measure of time perception? Are there any computerized tasks available??

Deleting outlier can be a daunting task. However, I have been using the box plot method from the SPSS and the z-score method. However, I am not sure when and which of the two method I should go for? Is there a text that details guidelines to the usage of these measures?

Thanks

I am planning to do a study on procrastination and l am looking for a scale that has been considered to be an industry standard to assess procrastination.

Hi!

I am trying to segregate different components of verbal working memory and visuospatial working memory.

In order to assess verbal working memory I am using an auditory version of n-back task with a load level from 1 to 2. The task requires the participant to respond when they here the same consonant repeatedly (1-back condition) or when they hear the same consonant at an interval of another consonant (2-back condition)

In order to assess visuopatial working memory I am using a spatial n-back task. The memory load ranges from 1 to 2. A set of cards are shown to the subjects sequentially, each card has a small back color dot on a white background. The position of the dot changes from card-to-card. The subject has to respond when they saw the dot appearing on the same location in comparison to the previous card (1-back condition) or after an interval of one card (2-back condition).

I am not sure whether it can segregate the components of verbal and visuospatial working memory.

Is there an article that might give me a clue as what component is tapped in the 1 n-back load level and 2 n-back load level?

Thanks

I am thinking to do a study on looking at the relationship between prospective memory and academic procrastination. Rationale is that procrastinator might delay a task intentionally but might forget to get back to the task a result of poor prospective memory?

is it possible?

Thanks
