Repeated-Measures for men and women viewing opposite sex visual stimuli?

#1
In advance, thank you for any insight you can provide on the following.

My study:

Men and women viewing different (opposite sex) stimuli (2 levels) and description (2 levels)

Men and women presented with same contextual scenarios (2 levels) before viewing stimuli

2 x DVs


I have read up on studies where men and women view opposite sex stimuli and would welcome guidance/confirmation that a repeated-measures design is appropriate for my study.

The studies I reviewed:

One study ran a repeated-measures ANOVA with
1 x DV
2 x IVs - women viewing male -opposite sex- stimuli (3 levels) and context (2 levels) as within-participant factors.

I’m assuming that if both women and men were in this study, the design would stay the same because they are viewing different stimuli?

Another study ran a within-sex MANOVA with
2 x DVs
2 x IVs - women and men viewing opposite sex stimuli (3 levels each) and partner status (2 levels). Separate analyses were conducted for men and women due to viewing of different stimuli (opposite sex stimuli).
So, in all, 2 x within-sex MANOVAs, one for women and one for men.
Authors’ noted …because different stimuli employed with men and women, a direct across-sex comparison was inappropriate. The authors went on to report on females and males separately. “…… females blah blah blah. Male participants, by contrast….” (significant effects were followed up with within-sex univariate ANOVA and paired t test post hoc analysis).


Am I correct then in adopting a repeated-measures/within-subject design for my study? I’ve been a little thrown off by some mention of a between-subjects design in my study environment.

Much appreciated

Sorry, but I don't quite understand. You have (how many?) men and
women in your study, each reads 1 out of 2 scenarios? Or both? Each
receives 1 out of 2 (or both?) stimuli etc.? What do you mean by "2x DVs"?
Maybe you could describe your experimental design in some more detail?
And what is your actual research question, what do you want to find out?

With kind regards

Thank you K. for your patience. I’ll clarify below:

Research question involves seeking out what information is being prioritized when men and women view opposite-sex stimuli

Sample:
20 men
20 women

Every male will view/read 20 opposite sex profiles - each profile will feature image and written info

Every women will view/read 20 opposite sex profiles – each profile will feature image and written info

(so, men will view profiles featuring women and, women will view profiles featuring men)

IVs:
• attractiveness (images) (2 levels)
• demographic info (written) (2 levels)
• context scenario (2 levels) men and women will be presented with the same context scenarios. Each will read the 1st context before viewing first block of profiles and then read the 2nd context before viewing 2nd block of profiles

DVs:
• eye-tracking metrics
• overall attractiveness ratings

Thank you and Kind regards

IVs:
• attractiveness (images) (2 levels)
• demographic info (written) (2 levels)
• context scenario (2 levels) men and women will be presented with the same context scenarios. Each will read the 1st context before viewing first block of profiles and then read the 2nd context before viewing 2nd block of profiles
So you have 4 combinations (a b c d) of attractiveness and
demographic info, each combination is presented 5 times?
And 10 combinations are presented within context 1 and 10
are presented within context 2? This would mean, for example,
that within context 1 you present a b c d a b c d a b, and within
context 2 you present c d a b c d a b c d?

With kind regards

Thank you K. for helping me to further clarify the study design.

“So you have 4 combinations (a b c d) of attractiveness and
demographic info, each combination is presented 5 times?“

Yes this is correct.
Women will see each opposite-sex combo 5 times
Men will see each opposite-sex combo 5 times


“And 10 combinations are presented within context 1 and 10
are presented within context 2?”


Yes, correct.

This would mean, for example,
that within context 1 you present a b c d a b c d a b, and within
context 2 you present c d a b c d a b c d?


Yes, correct.
But you have just enlightened me that participants will be viewing different/uneven combinations of stimuli between scenarios.

So, alternatively if the 4 combinations (abcd) were presented 4 times
Then I would have
8 combos presented within context 1 (abcd abcd)
8 combos presented within context 2 (abcd abcd)

Or

If the 4 combinations (abcd) were presented 6 times
Then I would have
12 combos presented within context 1 (abcd abcd abcd abcd)
12 combos presented within context 2 (abcd abcd abcd abcd)

I feel like I am developing a clearer understanding of the design

Am I correct to assume a within-subjects design because repeated measures are taken from women and repeated measures are taken from men?

Thank you for your expert teaching

This looks like a repeated-measures design with an additional
between-subjects factor male/female.

Disregarding male/female for the moment, there are 3 within-subject
factors with 2 levels each, so you have 8 cells within your design. If I
am correct, there should be 8 or 16 or 24 (etc.) stimuli (1 or 2 or 3 etc.
replications within each cell of the design) presented to each subject.
Do you want to aggregate a subject's measurements within each
combination (e.g. aggregate attractiveness ratings across all 5
replications of a combination)? It would be easy to perform repeated-
measures ANOVA then.

With kind regards
