Data of Emotional Responses to Visual Stimuli in Mexico

The data file includes the valence and arousal values per image. The next descriptive data per image: Arithmetic mean of valence, Valence standard deviation, Arithmetic mean of valence in women, Arithmetic mean of valence in men, Arithmetic mean of activation, Activation standard deviation, Arithmetic mean of activation in women and Arithmetic mean of activation in men. Also, the number of participants before and after the POMS filter.

PARTICIPANTS

Participants were recruited through an online study web application and
provided informed consent. No compensation was offered for their participation. The
National Council of Humanities, Science and Technology (CONAHCyT) fellowship
network of Mexico was utilized to distribute invitations for the online study. To ensure
spatial diversity in our sample, we adopted an unbiased sampling approach, as
recommended by Wang. This method involved random selection
from the population within the CONAHCyT fellowship network of Mexico.
CROSS-CULTURAL ANALYSIS OF EMOTIONAL RESPONSES 6
A total of 1540 adult participants, including university students pursuing
bachelor’s, master’s, and doctoral degrees, as well as academic staff, took part in the
study. Of the participants, 64.9% were male, and 35.1% were female. The distribution
of participants across different states of Mexico is detailed in Table 1.

MATERIALS
Mood Disturbance Filter
To minimize the potential influence of mood disturbances on our results, we implemented a mood filter. Participants exhibiting high mood disturbance were excluded from the analysis. This filter relied on the Profile Of Mood States (POMS) Questionnaire, specifically, a brief Spanish version of the research. There are six factors and their associated parameters, rated on a five-point Likert scoring system.
ANGER:
Angry
Grumpy
Irritable
Upset
Resentful
FATIGUE:
Exhausted
Tired
Weary
Weak
Exhausted
VIGOR:
Full of energy
Energetic
Active
Animated
Vigorous
FRIENDLINESS:
Kind
Comprehensive
Helpful
Friendly
Considered
TENSION:
Frayed nerves
Nervous
Uptight
Agitated
DEPRESSED:
Unhappy
Sad
Hopeless
Alone
Melancholic

IAPS Images
The visual stimuli were drawn from the International Affective Picture System (IAPS) database. A key strength of this study lies in the size of the
sample per image. We selected a total of 60 IAPS images, categorized as follows: 15 highly positive, 15 positive, 15 negative, and 15 highly negative.

Self-Assessment Manikin
The Self-Assessment Manikin (SAM) was used as the pictorial instrument to assess the IAPS images. SAM allowed us to measure the dimensions of valence, arousal, and dominance. Specifically: Affective valence, associated with pleasure, hedonism, or valence (SAM-Val), was rated on a scale ranging from a smiling figure (max. score of 9) to an unhappy one (min. score of 1). Arousal, reflecting activation or excitement (SAM-Act), was evaluated on a scale from a figure with open eyes (max. score of 9) to a very relaxed one (min. score of 1).
