Spontaneous trait transference occurs when communicators are perceived as possessing the very traits they describe in others. Study 1 confirmed that communicators become associated with the trait implications of their descriptions of others and that such associations persist over time. Study 2 demonstrated that these associations influence specific trait impressions of communicators. Study 3 suggested that spontaneous trait transference reflects simple associative processes that occur even when there are no logical bases for making inferences. Finally, Study 4 used more naturalistic stimuli and provided additional evidence that the phenomenon reflects mindless associations rather than logical attributions. Together these studies demonstrate that spontaneous trait transference is a reliable phenomenon that plays a previously unrecognized role in social perception and interaction.
