While the study of nationalism has received much attention throughout the social sciences and humanities, the experimental investigation of it lags behind. In this paper we review recent advances in the examination of implicit nationalism. In the first set of experiments we survey, the Palestinian, Israeli, Italian, and Russian flags were primed (or not, in the control conditions) and their effects on political thought and behavior were tested. In the second set the American or the Israeli flag was primed (or not) and prejudice toward African‐Americans or Palestinians (respectively) was examined. The results of all experiments suggest that the implicit activation of national cues has far‐reaching implications on political thought and behavior as well as on attitudes toward minorities. Under the assumption that the image of national flags is associated in memory with national ideologies, these results suggest that national ideologies can be implicitly pursued in a way that significantly affects our thoughts and behaviors.

This investigation used a newly developed artificial grammar learning (AGL) paradigm in which participants were exposed to sequences of stimuli that varied in two dimensions (colours and letters) that were superimposed on each other. Variation within each dimension was determined by a different grammar. The results of two studies strongly suggest that implicit learning in AGL depends on the goal relevance of the to-be-learned dimension. Specifically, when only one of the two stimulus dimensions was relevant for their task (Experiment 1) participants learned the structure underlying the relevant, but not that of the irrelevant dimension. However, when both dimensions were relevant, both structures were learned (Experiment 2). These findings suggest that implicit learning occurs only in dimensions to which we are attuned. Based on the present results and on those of Eitam, Hassin, and Schul (2008) we suggest that focusing on goal relevance may provide new insights into the mechanisms underlying implicit learning.

Current theories of emotion perception posit that basic facial expressions signal categorically discrete emotions or affective dimensions of valence and arousal. In both cases, the information is thought to be directly “read out” from the face in a way that is largely immune to context. In contrast, the three studies reported here demonstrated that identical facial configurations convey strikingly different emotions and dimensional values depending on the affective context in which they are embedded. This effect is modulated by the similarity between the target facial expression and the facial expression typically associated with the context. Moreover, by monitoring eye movements, we demonstrated that characteristic fixation patterns previously thought to be determined solely by the facial expression are systematically modulated by emotional context already at very early stages of visual processing, even by the first time the face is fixated. Our results indicate that the perception of basic facial expressions is not context invariant and can be categorically altered by context at early perceptual levels.

Is nonconscious goal pursuit useful in novel environments? The prevalent view of automaticity and control implies that an unconscious mode of goal pursuit can only reproduce formerly learned actions, and therefore that its usefulness in novel environments is very limited. Our results demonstrate that this conclusion is not always warranted, as nonconscious goal pursuit facilitated participants' learning of the structure of completely novel environments. Specifically, two experiments, using markedly different implicit-learning paradigms, demonstrated facilitation of implicit learning when the goal of achievement was primed. We propose that nonconscious goal pursuit can facilitate not only reproductive operations, but also productive ones, and that implicit learning is sensitive to the organism's nonconscious goals.

Across three experiments, the nonconscious perception of American cues increase the accessibility of aggressive constructs in memory, aggressive and negative judgments of other people, and aggressive displays of behavior following a mild provocation. These effects emerge only for American participants who regularly follow the American political news media. For American participants who do not follow the news, these effects are absent or tend to be in the opposite direction. Participants' political party orientation (Republican vs. Democratic) does not moderate any of the results. Interpretations and implications of the findings are discussed.
