Manipulating an Independent Variable through Embodiment

Przegląd

In any experiment, the researcher attempts to manipulate participants in one group to have different thoughts, experiences, or feelings than the other groups in the study.  Some manipulations are overt, while others can be quite subtle. Embodiment is a growing research area focused on the theory that subtle physical experiences can unconsciously influence a person’s thoughts. For example if a person physically smiles, it often leads to elevated mood. That is, the physical experience of smiling changes the way a person feels.

This video uses a two-group experiment to see if the physical sensation of weight will lead people to be stricter by giving harsher forms of discipline to fellow students who violated campus policies. 

Procedura

1. Define key variables.

  1. Create an operational definition (i.e., a clear description of exactly what a researcher means by a concept) of embodiment, or embodied cognition.
    1. For the purposes of this experiment, embodiment, or embodied cognition, involves the participant directly experiencing the physical sensation of weight in a non-obvious way that can unconsciously influence cognitions.

The data were collected from 122 participants. Recall that the discipline scale is calculated on the number assigned to each of the levels of discipline (e.g., 1 = verbal warning, etc.). To determine if there were differences between the heavy and light clipboard conditions on discipline levels, we performed a t-test for independent means.

The results indicated that participants who held the heavy clipboard gave stricter levels of discipline for 6 of the 7 violations (Figure 2). The only exception wa

Wniosek i Podsumowanie

This two-group experiment shows how researchers can manipulate participants’ cognition in a subtle way that participants are not aware of through embodiment. 

This study replicates and extends previous research on embodiment by Jostman et al., which showed that holding a weighted clipboard made participants think that fair decision-making through listening to students’ opinions was more important.1 

Embodiment effects are in
