Similar to the arousal data, the realness data contains a mixture of responses ranging from extreme values (0 and 1) to intermediate values between 0 and 1. Consequently, an ordered beta model was used for this data, as it is the most suitable for bounded data (e.g., survey sliders).For more information on these models see (Kubinec, 2022).

Here, we are examining the effect of various physical characteristics of the images to evaluate whether they influence the perceived realness of the images. Neither Entropy, Complexity, Contrast, nor Luminance significantly influence the perceived realness of the images, nor the likelihood of realness being above 0.5 (“RealnessBelief”), as indicated by the lack of significant effects.

This model examines the influence of sex, relevance, and condition on ratings of realness, incorporating random effects for participants and items.
Both genders significantly rate AI-generated images as less real than images labeled as photographs.
For males, this reduction in realness is consistent across all relevance categories. Specifically, males rate irrelevant images as significantly less real compared to relevant images. Additionally, males rate relevant AI-generated images as significantly less real compared to relevant photographs and rate irrelevant AI-generated images as significantly less real compared to irrelevant photographs.
For females, while they also rate AI-generated images as less real, the reduction is smaller. Females rate irrelevant AI-generated images as significantly less real compared to irrelevant photographs.
Both genders rate non-erotic images as more real than relevant images, with this difference being significant for females. For non-erotic images, males rate AI-generated images as significantly less real than photographs, but for females, this difference is not significant.

Here we look at whether the findings above are moderated by AI-Attitudes, Porn usage, or feedback.
This model examines how ratings of realness, predicted by sex, condition, and relevance, are moderated by beliefs about AI’s visual and textual capacities, self-reported knowledge of AI, as well as positive and negative attitudes towards AI (note that these results are relative to a baseline of male participants viewing relevant images labelled as photographs). Additionally, the model includes relevance and items as random effects.
Beliefs about AI’s visual capacity played a pivotal role in moderating realness ratings, showing nuanced effects across genders and image contexts. Both males and females generally rated images as more real as their beliefs in AI’s visual capabilities increased. However, this relationship varied significantly depending on the relevance of the images. For males, increased beliefs in AI’s visual capacity were associated with decreased realness ratings specifically when presented with irrelevant images. In contrast, females tended to rate both irrelevant and non-erotic images higher in realness as their beliefs in AI’s visual abilities increased. Notably, for females viewing irrelevant images labeled as AI-generated, higher beliefs in AI’s visual capacity led to decreased realness ratings, indicating a complex interaction.
Beliefs in AI’s textual abilities also influenced realness ratings, but the effects differed between genders and image contexts. Females showed lower realness ratings for irrelevant images labeled as AI-generated as their beliefs in AI’s textual abilities increased. Conversely, males demonstrated increased realness ratings only for non-erotic images labeled as AI-generated with higher beliefs in AI’s textual capabilities.
Self-reported knowledge of AI had distinct effects on realness ratings as well. Males rated non-erotic images lower in realness as their self-reported AI knowledge increased. In contrast, females rated irrelevant images labeled as AI-generated as more real with higher self-reported AI knowledge, suggesting divergent perceptions based on their understanding of AI.
Attitudes towards AI, whether positive or negative, further moderated ratings of realness. Positive attitudes generally enhanced realness ratings across genders. However, this effect was notably diminished for males when viewing irrelevant or non-erotic images labeled as AI-generated. Conversely, negative attitudes towards AI tended to decrease realness ratings for females, except when they viewed relevant images labeled as AI-generated, where negative attitudes paradoxically increased perceptions of realness.

This graph depicts differences in realness ratings based on beliefs about AI’s visual abilities for both genders when presented with images labeled as photographs or AI-generated. Notably, images labeled as photographs consistently receive higher realness ratings compared to those labeled as AI-generated, even at lower levels of belief in AI’s visual capacity. As beliefs in AI’s ability to generate realistic images increase, both genders show higher realness scores. However, for females with strong beliefs in AI’s visual capabilities, the difference in realness ratings between photographs and AI-generated labeled images becomes minimal.

This model examines how ratings of realness, predicted by sex, condition, and relevance, are moderated by porn usage.
Porn usage moderates the relationship between sex, relevance, condition, and realness ratings, but for males only. As porn usage increases, there is a significant decrease in realness ratings for non-erotic images labelled as AI-generated.

This model evaluates how ratings of realness, predicted by sex, condition, and relevance, are moderated by participants’ feedback.
Self-reported capacity to discriminate or not discriminate AI-generated images moderated realness ratings. Females who reported being able to discriminate AI-generated images tended to rate non-erotic images and relevant images labeled as AI-generated as more real.
In contrast, males who reported an inability to discriminate AI-generated images tended to rate images labeled as AI-generated as more real, regardless of the relevance of these images. Females who reported an inability to discriminate AI-generated images showed a different pattern, with realness ratings for images labeled as AI-generated decreasing for irrelevant images but increasing for relevant images.
Additionally, arousal ratings of AI-generated images also moderated realness ratings. Both genders rated AI-generated images as less real when reporting AI-generated images as being less arousing, with males showing a stronger effect, especially for relevant AI-generated labeled images.
Beliefs about the nature of labels as being reversed or incorrect also moderated realness ratings. Males’ realness ratings were lower when they believed that the labels were incorrect and lower when they believed the labels were reversed for non-erotic images. For females, lower realness ratings for AI-generated images were associated with believing the labels were reversed for relevant images

This graph depicts differences in realness ratings based on participants’ self-reported capacity to discriminate between AI-generated and real images, for both genders when presented with images labeled as photographs or AI-generated. The ability to discriminate AI-generated images is associated with higher realness ratings for both genders. However, females generally rate the realness of images lower than males across all conditions. The distinction between photographs and AI-generated images remains clear, with photographs being perceived as more real than AI-generated images. This difference is less pronounced for females who report an ability to discriminate AI-generated images.

Findings indicate a consistent perception across both genders that AI-generated images are perceived as less realistic compared to photographs. Interestingly, both genders rated non-erotic images as more realistic than relevant and irrelevant images.
As beliefs in AI’s ability to generate realistic images increases, both genders show higher realness scores.
Porn usage moderated realness ratings, only for men presented with AI-generated non-erotic images.
Males who reported an inability to discriminate AI-generated images perceived both relevant and irrelevant AI-generated images as more real, whereas females who reported this inability showed increased realness ratings only for relevant AI-generated images.
