The following passage explores the scientific debate surrounding cognitive abilities in primates.
Paragraph 1
For decades, comparative psychologists maintained that the ability to attribute mental states—beliefs, intents, desires, pretending, knowledge, etc.—to oneself and others was a uniquely human cognitive milestone, typically developing around age four. This "theory of mind" was conceptualized as a monolithic cognitive leap, separating human social reasoning from that of even our closest evolutionary relatives, the chimpanzees. Early experiments in the 1980s seemed to confirm this divide, showing that while chimpanzees could anticipate actions based on physical cues, they consistently failed tasks requiring them to understand that another agent could hold a false belief about the location of an object.
Paragraph 2
However, this paradigm began to shift with the implementation of eye-tracking technologies that measure anticipatory looking rather than active choice. When presented with scenarios where an actor was misled about the location of a hidden treat, chimpanzees consistently looked toward the location where the actor believed the food to be, rather than its actual current location. This subtle shift in experimental methodology revealed a level of implicit social cognition that went undetected by older, explicit choice paradigms, suggesting that the cognitive divide between humans and non-human primates might be a gradient of complexity rather than an absolute, qualitative barrier.
Paragraph 3
Despite these findings, several cognitive theorists remain skeptical, arguing that anticipatory looking does not necessarily equate to a representation of another's mental state. They propose that chimpanzees may simply be executing sophisticated behavioral rules—such as "people look for things where they last saw them"—without engaging in any internal simulation of the actor’s mind. Thus, the debate has shifted from whether primates possess theory of mind to how we can conclusively distinguish true mentalizing from highly complex behaviorist heuristics.
Which of the following best describes the relationship between Paragraph 2 and Paragraph 1?
- AParagraph 2 provides empirical data that validates and reinforces the traditional behavioral model introduced in Paragraph 1.
- BParagraph 2 contrasts the actions of chimpanzees with those of human subjects to support the developmental divide established in Paragraph 1.
- Paragraph 2 presents new experimental evidence that challenges the established scientific consensus described in Paragraph 1.Answer
- DParagraph 2 offers a speculative explanation for the evolutionary origin of the primate capabilities outlined in Paragraph 1.
