Language access differentially alters functional connectivity during emotion perception across cultures.

Introduction: It is often assumed that the ability to recognize the emotions of others is reflexive and automatic, driven only by observable facial muscle configurations. However, research suggests that accumulated emotion concept knowledge shapes the way people perceive the emotional meaning of others' facial muscle movements. Cultural upbringing can shape an individual's concept knowledge, such as expectations about which facial muscle configurations convey anger, disgust, or sadness. Additionally, growing evidence suggests that access to emotion category words, such as "anger," facilitates access to such emotion concept knowledge and in turn facilitates emotion perception. Methods: To investigate the impact of cultural influence and emotion concept accessibility on emotion perception, participants from two cultural groups (Chinese and White Americans) completed a functional magnetic resonance imaging scanning session to assess functional connectivity between brain regions during emotion perception. Across four blocks, participants were primed with either English emotion category words ("anger," "disgust") or control text (XXXXXX) before viewing images of White American actors posing facial muscle configurations that are stereotypical of anger and disgust in the United States. Results: We found that when primed with "disgust" versus control text prior to seeing disgusted facial expressions, Chinese participants showed a significant decrease in functional connectivity between a region associated with semantic retrieval (the inferior frontal gyrus) and regions associated with semantic processing, visual perception, and social cognition. Priming the word "anger" did not impact functional connectivity for Chinese participants relative to control text, and priming neither "disgust" nor "anger" impacted functional connectivity for White American participants. Discussion: These findings provide preliminary evidence that emotion concept accessibility differentially impacts perception based on participants' cultural background.

Unsupervised classification reveals consistency and degeneracy in neural network patterns of emotion.

In the present study, we used an unsupervised classification algorithm to reveal both consistency and degeneracy in neural network connectivity during anger and anxiety. Degeneracy refers to the ability of different biological pathways to produce the same outcomes. Previous research is suggestive of degeneracy in emotion, but little research has explicitly examined whether degenerate functional connectivity patterns exist for emotion categories such as anger and anxiety. Twenty-four subjects underwent functional magnetic resonance imaging (fMRI) while listening to unpleasant music and self-generating experiences of anger and anxiety. A data-driven model building algorithm with unsupervised classification (subgrouping Group Iterative Multiple Model Estimation) identified patterns of connectivity among 11 intrinsic networks that were associated with anger vs anxiety. As predicted, degenerate functional connectivity patterns existed within these overarching consistent patterns. Degenerate patterns were not attributable to differences in emotional experience or other individual-level factors. These findings are consistent with the constructionist account that emotions emerge from flexible functional neuronal assemblies and that emotion categories such as anger and anxiety each describe populations of highly variable instances.

Language Is a Unique Context for Emotion Perception.

Access to words used to label emotion concepts (e.g., "disgust") facilitates perceptions of facial muscle movements as instances of specific emotions (see Lindquist & Gendron, 2013). However, it remains unclear whether the effect of language on emotion perception is unique or whether it is driven by language's tendency to evoke situational context. In two studies, we used a priming and perceptual matching task to test the hypothesis that the effect of language on emotion perception is unique to that of situational context. We found that participants were more accurate to perceptually match facial portrayals of emotion after being primed with emotion labels as compared to situational context or control stimuli. These findings add to growing evidence that language serves as context for emotion perception and demonstrates for the first time that the effect of language on emotion perception is not merely a consequence of evoked situational context.

How people perceive the minds of the dead: The importance of consciousness at the moment of death.

Immortality is thought to be achieved through heroic deeds, reincarnation, and the afterlife. The present studies reveal an alternative path to transcending death: dying while conscious. Seven studies demonstrate that dying while more awake, aware and/or lucid leads people to see a richer postmortem mind-an effect we call conservation of consciousness. People see more mind in the deceased when they die with their eyes open (Study 1), and while awake (vs. in a coma), while suffering from ALS (vs. from Alzheimer's), while on hallucinogens (vs. sedatives), and while dreaming (vs. in a deep sleep; Study 2). This effect is robust, holding even in a between-subjects design, and even when participants are explicitly encouraged to interpret the mind perception items literally (Study 3). Perceived conservation of consciousness after death is driven more by general perceived awareness than by fear of death (Study 4) and predicts perceptions of mind beyond having a vivid (vs. dull) life (Study 5). The last wishes of the dying are also given more moral weight if made by those who ultimately die while conscious (Study 6). Perceived conservation of consciousness also occurs in the real-world context of a historic cemetery (Study 7). These results reveal a simple way to increase your influence after death and highlight both the power of endings and the subjective nature of mind.

To Be Immortal, Do Good or Evil.

Many people believe in immortality, but who is perceived to live on and how exactly do they live on? Seven studies reveal that good- and evil-doers are perceived to possess more immortality-albeit different kinds. Good-doers have "transcendent" immortality, with their souls persisting beyond space and time; evil-doers have "trapped" immortality, with their souls persisting on Earth, bound to a physical location. Studies 1 to 4 reveal bidirectional links between perceptions of morality and type of immortality. Studies 5 to 7 reveal how these links explain paranormal perceptions. People generally tie paranormal events to evil spirits (Study 5), but this depends upon location: Evil spirits are perceived to haunt houses and dense forests, whereas good spirits are perceived in expansive locations such as mountaintops (Study 6). However, even good spirits may be seen as trapped on Earth given extenuating circumstances (Study 7). Materials include a scale for measuring trapped and transcendent immorality.

When a word is worth a thousand pictures: Language shapes perceptual memory for emotion.

Across 3 studies we show that emotion words support the acquisition of conceptual knowledge for emotional facial actions that then biases subsequent perceptual memory for later emotional facial actions. In all studies, participants first associated emotional facial actions with a word during a learning phase or completed a control task. In a target phase, participants studied slightly different category exemplars. During a final test phase, participants identified which face the individual had been making during the target phase (i.e., the learned face, the target face, or a morphed combination). Studies 1 and 2 demonstrate that pairing never-before-seen "alien" facial actions with nonsense words during the learning phase biases perceptual memory for facial actions subsequently viewed during the target phase. Study 3 replicates these findings with the familiar emotion categories fear and anger. Across all 3 studies, participants were more likely to choose the face that had been linked with a word during the learning phase than the face actually studied in the target phase. These findings suggest that pairing facial actions with words can shape later perceptual memory for emotional facial actions. (PsycINFO Database Record
