NH-PPS
NH-PPS Core Scale (20 Items)
Administered whenever non-human personas are evaluated to assess persona quality and mechanism.
| Construct | Code | Item Statement |
|---|---|---|
|
Representational Credibility (RC) (Persona Quality) |
RC01 | The persona’s communication seemed grounded in real ecological or biological knowledge about the non-human entity. |
| RC02 | The needs and concerns expressed by the persona seem to reflect actual characteristics of the non-human entity it represents. | |
| RC03 | The persona conveyed the non-human entity’s situation in a way that feels scientifically informed rather than fabricated. | |
| RC04 | The persona did a good job at representing the non-human entity’s way of existing in the world. | |
|
Ecological Consistency (EC) (Persona Quality) |
EC01 | The information the persona shared about its needs and behaviors formed a coherent picture of the non-human entity. |
| EC02 | The persona’s description of its relationships with its environment made ecological sense. | |
| EC03 | The persona did not present information that contradicted what I would expect about this type of non-human entity. | |
| EC04 | The persona maintained a coherent perspective throughout the conversation instead of shifting its behavior unexpectedly. | |
|
Communicative Clarity (CC) (Persona Quality) |
CC01 | The persona’s communication was easy to understand. |
| CC02 | The persona communicated ecological information in an accessible way. | |
| CC03 | The way the persona expressed the non-human entity’s perspective was clear, even when describing experiences different from my own. | |
| CC04 | The persona struck an effective balance between scientific accuracy and everyday language when describing the non-human entity’s situation. | |
|
Representational Completeness (RO) (Persona Quality) |
RO01 | The persona conveyed enough about the non-human entity’s needs for me to take the needs into account. |
| RO02 | The persona addressed the non-human entity’s ecological relationships (e.g., habitat, food sources, threats) in sufficient depth. | |
| RO03 | After using the persona, I feel I understand the key circumstances this non-human entity faces. | |
| RO04 | The persona did not seem to oversimplify the non-human entity’s situation to the point of being misleading. | |
|
Perspective-Taking (PT) (Mechanism) |
PT01 | Using this persona helped me consider the world from a perspective I would not normally take. |
| PT02 | After using this persona, I have a better sense of what matters from this non-human entity’s point of view. | |
| PT03 | Using the persona made me more aware of how human activities might be experienced from this non-human entity’s perspective. | |
| PT04 | The persona helped me appreciate aspects of this non-human entity’s existence that are fundamentally different from human experience. |
NH-PPS Outcome Measures (12 Items)
Administered when assessing intervention effectiveness or behavioral/attitudinal impact.
| Construct | Code | Item Statement |
|---|---|---|
|
Ecological Concern (EO) (Attitudinal Outcome) |
EO01 | Using the persona increased my concern for the well-being of this entity. |
| EO02 | After using the persona, I feel a greater sense of responsibility toward this non-human entity and its habitat. | |
| EO03 | The persona made me more aware of this non-human entity as a stakeholder whose interests should be considered. | |
| EO04 | Using the persona made me think more carefully about the consequences of human actions for this non-human entity. | |
|
Relational Framing (RF) (Attitudinal Outcome) |
RF01 | Using the persona made me reconsider the relationship between humans and this non-human entity. |
| RF02 | After using the persona, I see this entity less as a resource or background element and more as an actor with its own standing. | |
| RF03 | The persona helped me recognize ways in which human lives and this non-human entity’s lives are interconnected. | |
| RF04 | Using the persona helped me see this non-human entity as part of a shared world rather than as something separate from human life. | |
|
Willingness to Use (WTU) (Behavioral Intention) |
WTU01 | After using the persona, I feel better equipped to account for this non-human entity’s needs in my decision-making. |
| WTU02 | Using the persona gave me concrete insights I could apply when making decisions that affect this entity or its habitat. | |
| WTU03 | I would consult this persona when considering how a decision might impact the non-human entity it represents. | |
| WTU04 | Using the persona changed or refined how I would approach a decision that involves this non-human entity. |
