Attitudes as propositional representations

Highlights

  • Attitude research was for a long time dominated by an associative perspective that views attitudes as associations between representations in memory.

  • New theories have argued that attitudes constitute propositional representations, which, in contrast to associations, specify relational information and have a truth value.

  • Recent research on evaluative conditioning and implicit evaluation, two phenomena that were originally thought to be underpinned by associations, supports the propositional perspective on attitudes.

  • The propositional perspective on attitudes has inspired new ways to measure, predict, and influence (evaluative) behavior.

Attitudes are mental representations that help to explain why stimuli evoke positive or negative responses. Until recently, attitudes were often thought of as associations in memory. This idea inspired extensive research on evaluative conditioning (EC) and implicit evaluation. However, attitudes can also be seen as propositional representations, which, unlike associations, specify relational information and have a truth value. We review research on EC and implicit evaluation that tested the basic tenets of the propositional perspective on attitudes. In line with this perspective, studies show that both phenomena are moderated by relational and truth information. We discuss implications for the prediction and influencing of seemingly irrational behavior such as excessive alcohol intake and implicit racial bias.

Attitudes: a brief history

From a cognitive perspective, attitudes (see Glossary) can be conceptualized as mental representations that determine how we evaluate stimuli; that is, whether we respond in positive or negative ways to stimuli in our environment (evaluation). Thus, attitudes are assumed to be a crucial driving force behind much of what we do, think, and feel [1]. It is therefore unsurprising that cognitive researchers have spent considerable effort trying to understand the nature of attitudinal

A propositional perspective on attitudes

Rather than thinking of attitudinal representations as associations, they also can be conceived of as propositional representations. For instance, a positive attitude toward a particular brand of coffee (e.g., Brand X) could be seen as a representation that specifies the information ‘Brand X is good’ (Figure 1, Key figure). In contrast to (simple) associative representations, propositional representations can specify information about how concepts are related. For instance, unlike an

Relational information moderates EC

If EC occurs because beliefs about stimulus valence (e.g., Brand X is good) are inferred from beliefs about the relation between stimuli (e.g., Brand X co-occurs with Actor Y, Actor Y likes Brand X), information about the specific relation between stimuli could influence beliefs about stimulus valence and thus the strength and direction of EC effects. In line with this reasoning, EC has been found to depend heavily on information about how a CS and a US are related (see [24,25] for reviews). In

Relational information moderates implicit evaluation

From a propositional perspective, pre-existing propositional representations in memory can be activated under suboptimal conditions and novel propositional representations can be formed as the result of inferences that are made under suboptimal conditions. Both processes can give rise to implicit evaluation [20,21]. For instance, if the belief ‘Brand X is good’ has been entertained in the past, it is represented in memory and can thus be retrieved from memory, also under suboptimal conditions.

Concluding remarks

We hope to have shown that the propositional perspective on attitudes provides a viable and useful alternative to the associative perspective on attitudes. It not only offers a potential explanation for phenomena like EC and implicit evaluation but also inspired many new studies on these phenomena. The results of these studies have drastically changed the way we think about EC and implicit evaluation: rather than being simple phenomena based on an primitive associative mechanism, EC and

Glossary

Association
a link between nodes in memory via which activation can spread.
Attitude
a mental representation that mediates stimulus evaluation; that is, that allows stimuli to evoke evaluative responses.
Automatic
an umbrella concept that can refer to the different ways in which conditions are suboptimal for cognitive processing (synonym of implicit).
Believability
the extent to which information is considered to be true or false.
Diagnosticity
the extent to which information allows conclusions.
