Herbert Clark argues that language use is more than the sum of a speaker speaking and a listener listening. It is the joint action that emerges when speakers and listeners, writers and readers perform their individual actions in coordination, as ensembles. In contrast to work within the cognitive sciences, which has seen language use as an individual process, and to work within the social sciences, which has seen it as a social process, the author argues strongly that language use embodies (...) both individual and social processes.

I examine the phenomenon of implicit learning, the process by which knowledge about the rule-governed complexities of the stimulus environment is acquired independently of conscious attempts to do so. Our research with the two seemingly disparate experimental paradigms of synthetic grammar learning and probability learning, is reviewed and integrated with other approaches to the general problem of unconscious cognition. The conclusions reached are as follows: Implicit learning produces a tacit knowledge base that is abstract and representative of the structure of (...) the environment; such knowledge is optimally acquired independently of conscious efforts to learn; and it can be used implicitly to solve problems and make accurate decisions about novel stimulus circumstances. Various epistemological issues and related problems such as intuition, neuroclinical disorders of learning and memory, and the relationship of evolutionary processes to cognitive science are also discussed.

The uncanny valley—the unnerving nature of humanlike robots—is an intriguing idea, but both its existence and its underlying cause are debated. We propose that humanlike robots are not only unnerving, but are so because their appearance prompts attributions of mind. In particular, we suggest that machines become unnerving when people ascribe to them experience, rather than agency. Experiment 1 examined whether a machine’s humanlike appearance prompts both ascriptions of experience and feelings of unease. Experiment 2 tested whether a machine capable (...) of experience remains unnerving, even without a humanlike appearance. Experiment 3 investigated whether the perceived lack of experience can also help explain the creepiness of unfeeling humans and philosophical zombies. These experiments demonstrate that feelings of uncanniness are tied to perceptions of experience, and also suggest that experience—but not agency—is seen as fundamental to humans, and fundamentally lacking in machines.

When someone steps on your toe on purpose, it seems to hurt more than when the person does the same thing unintentionally. The physical parameters of the harm may not differ—your toe is flattened in both cases—but the psychological experience of pain is changed nonetheless. Intentional harms are premeditated by another person and have the specific purpose of causing pain. In a sense, intended harms are events initiated by one mind to communicate meaning (malice) to another, and this could shape (...) the recipient’s experience. This study examined whether self-reported pain is indeed higher when the events producing the pain are understood as intentionally (as opposed to unintentionally) caused by another person. Although pain was traditionally conceived to be solely physical in nature (Aydede, 2005), its experience varies substantially with psychological context. The placebo analgesia effect, for example, is the reduction of pain without a change in physical stimulation when context, expectations, or sugar pills challenge the interpretation of a sensation as painful (e.g., Fields, 2008). The nocebo effect, in turn, is the experience of pain without any physical stimulation—as when participants report headaches when told that a (nonexistent) electric current is passing through their heads (Schweiger & Parducci, 1981). These variations in pain experience seem to depend on the meaning of the stimulus: A sugar pill is meant to decrease pain, whereas electric current is meant to increase pain. In an interpersonal context, the meaning of an action is derived from the would complete. perceiver’s perceptions of the actor’s intention (Clark, 1996). (shrink)
