Image generated with Nightcafe. Prompt: "A texture of multiple colorful synth waves with gold accents."
See your stimuli move a little (or a lot!) using the RAISE methodology.

The RAISE method can manipulate fine body movement. We focus on inducing a smile. Research shows that observing a smile can influence consumer perceptions. While the physical characteristics of a smile must sometimes be tightly controlled (e.g., measuring a Duchenne smile: Ilicic, Kulczynski, and Baxter, 2018), in other situations, the mere presence, or the intensity, of a smile is sufficient for experimental manipulation.
We focus on this latter approach – an example is Chang et al. (2021), who manipulate smile intensity. In our case, we will manipulate the presence or absence of a smile. RAISE can be applied to manipulate smile presence. Similar to the services marketing and waiter gender example, the process begins with an initial prompt indicating the desired features of Stimulus A –in this case, the smiling condition:

The desired image is generated. Per the RAISE methodology, Stimulus B is then generated conditional on the image of Stimulus A, a suitable image strength (40%), and an updated text prompt:
Below is a handy summary card outlining the process you just learned:
As can be seen, the presence or absence of a smile is evident across stimuli. However, even though the text prompt required a white background, our Stimulus A (and, thus, B as well) instead depicts a blurred background. Head to the Technical Details section for more information on how to refine stimuli backgrounds.
