Easy to Make, Hard to Revise: Updating Spontaneous Trait Inferences in the Presence of Trait-Inconsistent Information

Previous research has shown that perceivers spontaneously form trait inferences from others' behaviors received at a single point in time. The present work examined the persistence of spontaneous trait inferences (STIs) in the presence of trait-inconsistent information about others. We hypothesized that STIs should be resistant to change over time and in the presence of new trait-inconsistent information due to perceivers forming and storing multiple STIs independently in memory. Consistently, Experiments 1a and 1b showed that initial STIs were not affected by new trait-inconsistent information. Experiments 2 and 3 revealed that STIs were persistent over 48 hours. Two experiments also tested memory reconsolidation as a possible mechanism of updating first impressions. While STIs were not substantially affected, spontaneous goal inferences (SGIs) were elevated among those with a better explicit memory of behaviors after learning trait-inconsistent information following a memory reactivation procedure. Implications of these findings on impression formation and updating processes are discussed.

The effect of stereotype activation on spontaneous inferences

We adopted the probe recognition paradigm to examine the effect of stereotype activation on spontaneous inferences among Chinese undergraduates (N = 48). First, behavioral sentences involving trait-implying behavior and corresponding situational information were simultaneously presented. We then selected stereotype labels of the actor's behavior that were consistent or inconsistent with the behavior, and which were activated either supraliminally or subliminally. The results showed that whether a stereotype was activated supraliminally or subliminally, the influence on spontaneous inferences was the same. Specifically, when the stereotype was inconsistent with the actor's behavior, spontaneous situational inferences were facilitated, and when the stereotype was consistent with the actor's behavior, spontaneous trait inferences were not facilitated. As Chinese people may be more prone to spontaneous (vs. trait) inferences, this indicates that human inferences are deeply influenced by culture.

Consequences of being unable to categorize: Racial ambiguity and spontaneous trait inferences

Limited research has examined impression formation in the context of dual or ambiguous group membership. This research examined the consequences of being unable to categorize by investigating the influence of racial ambiguity on spontaneous trait inferences (STIs). Participants (N = 112) completed a savings-in-relearning paradigm, designed to measure the formation of STIs (Carlston & Skowronski, 1994). STI formation for racially ambiguous and racially unambiguous (i.e., easily categorizable) faces was compared. Results suggest that racial ambiguity impaired perceiver’s ability to form STIs, a basic impression formation process. Implications of these findings for social perception and social interaction are discussed.

On the Assumptions That We Make About the World Around Us: A Conceptual Framework for Feature Transformation Effects

Various phenomena such as halo effects, spontaneous trait inferences, and evaluative conditioning have in common that assumptions about object features (e.g., whether a person is intelligent or likeable) are influenced by other object features (e.g., whether that person is attractive or co-occurs with other liked persons). Surprisingly, these phenomena have rarely been related to each other, most likely because different phenomena are described using different terms. To overcome this barrier, we put forward a conceptual framework that can be used to describe a wide range of these phenomena. After introducing the four core concepts of the framework, we illustrate how it can be applied to various phenomena. Doing so helps to reveal similarities and differences between those phenomena, thus improving communication and promoting interactions between different areas of research. Finally, we illustrate the generative power of the framework by discussing some of the new research questions that it highlights.

Multiple Behavior Descriptions Affect the Acquisitions of STI and STT

Four studies pursued the idea that spontaneous trait inferences (STIs) involve the formation of both inferential knowledge and associative knowledge while spontaneous trait transferences (STTs) involve only the formation of associative knowledge. These studies varied the type and amount of behavioral information from which perceivers could extract trait information. Experiments 1a and 1b used a modified savings-in-relearning paradigm and demonstrated that repeated presentations of an individual and a behavior description increased the strength of association between the target and implied trait, and this effect did not depend on whether the repeated presentations involved redundant information or new information. In comparison, Experiments 2a and 2b used a trait ratings dependent variable and demonstrated that the effects of repetition were stronger for STI, but not STT, when the added information differed from information that was previously encountered, but not when it was redundant with the previously encountered information.
