Implicit evaluation bias induced by approach and avoidance

We report a study in which faces with a neutral emotional expression were shown on a computer screen. By means of a joystick, participants pulled half of the faces closer (positive approach movement), and pushed the half away (negative avoidance movement). As a result, an operant evaluative conditioning effect occurred in a subsequent affective priming task: Participants responded more quickly to positive target words if they were preceded by a previously pulled face than a pushed face, and vice versa for negative target words. The effect became stronger the more often the faces had been trained to approach or to avoid. No effect was observed on explicit evaluations of the faces: Pushed faces were rated as sympathetic as pulled ones.     

How farsighted are behavioral tendencies of approach and avoidance? The effect of stimulus valence on immediate vs. ultimate distance change

Research suggests that affective stimuli facilitate behavior that causes a compatible change in distance (i.e., approach positive and avoid negative stimuli). In natural settings, however, behavior often causes different consequences at different points in time. It is unclear whether affective stimuli interact with immediate or ultimate action-consequences (i.e., consequences that are more removed in time). To shed light on this, we tested whether stimulus valence facilitates behavior that ultimately causes a compatible change in distance, even when this behavior immediately causes an incompatible distance change. Participants moved a manikin on a computer screen toward or away from a positive or negative word. On half of the trials, moving the manikin ultimately in one direction required an initial movement in the opposite direction. Results from two studies showed that stimulus valence facilitated ultimate-compatible distance change regardless of the initial direction. This suggests that affective stimuli facilitate behavior that is relatively farsighted.     

Dogmatism and information gathering in personality impression formation

Subjects were assigned the task of forming an impression of another person with information being gathered from two conflicting sources. One half were given a positive first impression, and one half were given a negative first impression before allowing them to select additional information. Final ratings were made when Ss indicated that they had taken sufficient information. Dogmatic Ss took in less information before passing “final judgment,” gave more extreme stability ratings, expressed greater liking for their agreed-with source, and showed a trend toward a preference for explaining away impression-discrepant information rather than to withhold judgment.     

Judging Words at Face Value: Interference in a Word Processing Task Reveals Automatic Processing of Affective Facial Expressions

Earlier research has indicated that some characteristics of facial expressions may be automatically processed. This study investigated automaticity as evidenced by involuntary interference in a word evaluation task. Compound stimuli, consisting of words superimposed on pictures of affective faces, were presented to subjects who were given the task of evaluating the affective valence of the words while disregarding the faces. Results of three experiments showed that word evaluation was influenced by the concurrently shown affective faces. Overall, negative words were found to require longer latencies, indicating that more processing resources are invested in negative than in positive stimuli. This speed advantage for positive words was modified by the faces. Negative words were facilitated, relative to positive ones, when shown with a negative expression (e.g. a sad face). Correspondingly, negative words were inhibited, relative to positive ones, when shown with a positive expression (e.g. a happy face). The results are consistent with automatic, involuntary semantic processing of affective facial expressions.     

高社交焦虑个体对正性面孔的解释偏差

本研究采用情绪启动范式考察社交焦虑个体对正性刺激解释偏差。研究以正性和打碎的面孔为启动项,正性或负性非社交词为目标项,要求高社交焦虑组被试和控制组被试判断目标项的情感色彩,并记录其反应时与准确率。结果发现,两组被试具有不同的情绪启动模式：高焦虑组被试未表现出显著地相容性效应;他们在正性-正性条件下的反应时显著慢于控制组被试。研究结果提示高社交焦虑个体具有对正性社交刺激的解释偏差,他们不能充分理解正性社交刺激的积极含义。     

I like the sound of your voice: Affective learning about vocal signals

This paper provides the first demonstration that the content of a talker’s speech is sufficient to imbue the acoustics of his voice with affective meaning. In two studies, participants listened to male talkers utter positive, negative, or neutral words. Next, participants completed a sequential evaluative priming task where a neutral word spoken by one of talkers was presented before each target word to be evaluated. We predicted, and found, that voices served as evaluative primes influencing the speed with which participants evaluated the target words. These two experiments demonstrate that the human voice can take on affective meaning merely based on the positive or negative value words it has spoken. Implications for affective processing, the pragmatics of communication, and person perception are discussed.     

Asymmetries in the processing of emotionally valenced words

Earlier research has shown a valence dependent encoding asymmetry of emotional words (e.g., Pratto & John, 1991; White, 1996; Stenberg, Wiking & Dahl, 1998). To further study this asymmetry, two word detection experiments were performed based on the following hypothesis: when there is a more thoroughly processing of the valence, in this case a valence categorisation, there will be, in a subsequent task, prolonged latencies for negative words, compared to positive words. The result gave significantly prolonged response latencies for negative words compared to positive ones in the subsequent detection task when using an affective orienting task, something not found using a non-affective orienting task. The results support the Mobilization-Minimization hypothesis (Taylor, 1991), according to which negative events and stimuli occupy more cognitive resources, but with some limitation: the affective asymmetry, with prolonged latencies for negative words, occurs only when there is a deepened encoding of the affective component of the words.     

情绪名词的具体性效应：来自ERP的证据

词汇的具体性和情绪性是影响词汇加工的不同因素, 高具体性和情绪性都能够促进词汇的加工。本研究同时操纵词汇的具体性和情绪性, 使用词汇判定任务和愉悦度判断任务, 探讨了情绪名词的具体性效应及其具体性效应是否受词汇情绪信息的影响。结果发现：情绪名词的具体性效应受内隐或外显情绪条件的影响, 具体的情绪词比抽象的情绪词反应时间更短、正确率更高, 诱发了更大的N400和减小的LPC, 但LPC的具体性效应只表现在内隐情绪任务中。词汇的具体性和情绪性的相互影响发生在内隐情绪任务中的语义加工阶段, 正性、负性的具体词和抽象词的加工在N400成分上差异不显著, 而中性具体词和抽象词在N400成分上差异显著, 说明词汇的情绪信息为抽象词的加工提供了充分的语境, 因此消除了具体词的加工优势。     

Shifts in attention biases in response to acute pain induction: examination of a model of "conversion" among repressors

Unlike most people, those who are characterized by a repressive coping style report high levels of physical (sensory) pain but low levels of emotional distress (affective pain), which is a discrepancy that may suggest a "conversion" process. In two studies, we tested an attention allocation model, proposing that repressors direct attention away from threatening negative affective information and toward nonthreatening physical pain information during emotionally arousing (painful) situations. In Study 1, 84 participants underwent a cold pressor and then recovered. Repressors reported greater pain during recovery than low- and high-anxious participants, but they reported lower distress than high-anxious participants. Repressors reported significant and large discrepancies between high pain and low distress, whereas these differences were less pronounced for other groups. In Study 2, 77 participants underwent an ischemic pain task while performing a modified dot-probe task with sensory and negative affective pain words as stimuli. Repressors showed increasing biases away from affective pain words and toward sensory pain words as the pain task continued, whereas low- and high-anxious participants did not show these shifts in attention. The results support the notion that conversion among repressors may involve a process by which attention is directed away from emotional distress during noxious stimulation and is focused instead on sensory information from pain.     

On wildebeests and humans: the preferential detection of negative stimuli

On the basis of a functional perspective, we hypothesized that negative stimuli are detected faster than positive stimuli. In Experiment 1, participants were subliminally presented with positive and negative words or with no words at all. After each presentation, participants were asked whether they had seen a word. They detected negative words more accurately than positive words. In Experiment 2, participants were subliminally presented with negative or positive words. After each presentation, they were asked whether the presented word was positive or negative. Negative words were correctly categorized more often than positive words. Experiment 3 showed that although participants correctly categorized negative words more often than positive words, they could not guess the meaning of the words better than would be expected by chance. The results are discussed against the background of recent findings on basic affective processes.     

Temporospatial analysis of explicit and implicit processing of negative content during word comprehension

Although divergences between explicit and implicit processing of affective content during word comprehension have been reported, the underlying nature of those differences remains in dispute. Prior studies focused on either the timing or the spatial location of the effects. The present study examined the precise dynamics of the processing of negative words when attention is directed to affective content or to non-emotional properties by capitalizing on fine temporal resolution of the event-related potentials (ERPs) and recent advances in source localization. Tasks were used that required accessing knowledge about different semantic properties of negative and neutral words. In the direct task, participants’ attention was directed towards emotional information. By contrast, subjects had to decide whether the words’ referent could be touched or not in the indirect task. Regardless of being processed explicitly or implicitly, negative compared to neutral words were associated with more errors and greater key pressure responses. Electrophysiologically, affective processing was reflected in larger amplitudes to negative words in a late positive component (LPC) at the scalp level, and in increased activity in the pre-supplementary motor area (pre-SMA) at the voxel level. Interestingly, an interaction between emotion and type of task was observed. Negative words were associated with more errors, larger anterior distributed LPC amplitudes and increased activity in the posterior cingulate cortex (PCC) in the direct compared to the indirect task. This LPC effect was modulated by the concreteness of the words. Finally, a task effect was found in a posterior negativity around 220 ms, with enhanced amplitudes to words in the direct compared to the indirect task. The present results suggest that negative information contained in written language is processed irrespective of controlled attention is directed to it or not, but that this processing is reinforced in the former case.     

Approach–avoidance actions or categorization? A matching account of reference valence effects in affective S–R compatibility

Theories from diverse areas of psychology assume a compatibility relation between affective stimuli and approach–avoidance actions and imply that the reference object (self vs. other) for the movement determines the direction of the compatibility effect. However, studies on the influence of reference valence are still sparse. We conducted three experiments to test a matching account of actions that move targets toward or away from a centrally located referent. When the referent was positive (Albert Einstein), participants were faster to move positive words toward and negative words away from the referent than to move negative words toward and positive words away from the referent. When the referent was negative (Adolf Hitler), these relations reversed. These results cannot be interpreted with current motivational or cognitive accounts but are in accord with the matching account.

Effects of displayed emotion on attitude and impression formation in visual speech-reading

In two experiments on visual speech-reading, with a total of 132 normal-hearing participants, the effects of displayed emotion and task specificity on speech-reading performance, on attitude toward the task and on person impression were explored, as well as associations between speech-reading performance, attitude, and person impression. The results show that displayed emotion increased speech-reading performance and attitude ratings, and that the actor was perceived as more extraverted both when displaying emotions, and when his speech was high in specificity The main conclusion was that displayed emotion enhances speech-reading performance by providing information that is useful to the speech-reader.     

Temperamental contributions to children's performance in an emotion-word processing task: a behavioral and electrophysiological study

Seven-year-old children (N=65) participating in a study of the influence of infant temperament on socioemotional development performed an auditory selective attention task involving words that varied in both affective (positive vs. negative) and social (social vs. nonsocial) content. Parent report of contemporaneous child temperament was also collected, and individual differences in self-regulation in the affective (soothability) and cognitive (attentional control) domains were noted. Overall, children showed slower responses to stimuli that were either social or negative in content, with the largest effect elicited by words that possessed both traits. Children rated high in soothability and attentional control showed slower responses to social negative words. The other children showed little to no differential response patterns across the word categories. ERPs collected during the task indicated that processing differences were evident in the later more cognitive components of the ERP, especially in children low in attentional control. These findings indicate that performance on an auditory selective attention task can assist in identifying underlying patterns of affective processing.     

Polarity correspondence in metaphor congruency effects: structural overlap predicts categorization times for bipolar concepts presented in vertical space

Previous research has shown that words presented on metaphor congruent locations (e.g., positive words UP on the screen and negative words DOWN on the screen) are categorized faster than words presented on metaphor incongruent locations (e.g., positive words DOWN and negative words UP). These findings have been explained in terms of an interference effect: The meaning associated with UP and DOWN vertical space can automatically interfere with the categorization of words with a metaphorically incongruent meaning. The current studies test an alternative explanation for the interaction between the vertical position of abstract concepts and the speed with which these stimuli are categorized. Research on polarity differences (basic asymmetries in the way dimensions are processed) predicts that +polar endpoints of dimensions (e.g., positive, moral, UP) are categorized faster than -polar endpoints of dimensions (e.g., negative, immoral, DOWN). Furthermore, the polarity correspondence principle predicts that stimuli where polarities correspond (e.g., positive words presented UP) provide an additional processing benefit compared to stimuli where polarities do not correspond (e.g., negative words presented UP). A meta-analysis (Study 1) shows that a polarity account provides a better explanation of reaction time patterns in previous studies than an interference explanation. An experiment (Study 2) reveals that controlling for the polarity benefit of +polar words compared to -polar words did not only remove the main effect of word polarity but also the interaction between word meaning and vertical position due to polarity correspondence. These results reveal that metaphor congruency effects should not be interpreted as automatic associations between vertical locations and word meaning but instead are more parsimoniously explained by their structural overlap in polarities.     

The effects of the concreteness of differently valenced words on affective priming

This study aimed to determine whether affective priming is influenced by the concreteness of emotional words. To address this question, we conducted three experiments using lexical decision-priming task. In Experiment 1, positive-abstract (PA) and positive-concrete (PC) words were used as primes to examine the effect of the concreteness of positive words on affective priming, and in Experiment 2, negative-abstract (NA) and negative-concrete (NC) words were used as primes to examine the effect of the concreteness of negative words on affective priming. Results showed that participants responded faster to affectively congruent-abstract trails than incongruent-abstract trails in PA prime conditions, but for PC or negative word (NC and NA) prime conditions, there were no differences between the response times of congruent trails and incongruent trails. To examine the reliability of the priming effects observed in Experiments 1 and 2, we set up a neutral condition as a baseline in Experiment 3, through which we confirmed the difference in the affective priming effect between positive and negative primes in a concrete–abstract dimension. PA words were found to have the tendency to possess more emotional load and facilitate affective association between the prime and the target. The study finding suggests that aside from arousal and valence, the concreteness of positive words also has an impact on affective priming effect.     

Primacy of emotional vs. semantic scene recognition in peripheral vision

Emotional scenes were presented peripherally (5.2° away from fixation) or foveally (at fixation) for 150 ms. In affective evaluation tasks viewers judged whether a scene was unpleasant or not, or whether it was pleasant or not. In semantic categorisation tasks viewers judged whether a scene involved animals or humans (superordinate-level task), or whether it portrayed females or males (subordinate-level task). The same stimuli were used for the affective and the semantic task. Results indicated that in peripheral vision affective evaluation was less accurate and slower than animal/human discrimination, and did not show any advantage over gender discrimination. In addition, performance impairment in the peripheral relative to the foveal condition was greater or equivalent for affective than for semantic categorisation. These findings cast doubts on the specialness and the primacy of affective over semantic recognition. The findings are also relevant when considering the role of the subcortical “low route” in emotional processing.     

The evaluation-behavior link: Direct and beyond valence

The present research tests the hypothesis that affective stimuli automatically trigger approach/avoidance tendencies. A first experiment showed that in a vigilance task participants responded faster with an approach behavior (i.e., arm flexion) to happy words than to sad words and faster with an avoidance behavior (i.e., arm extension) to sad than to happy words that were presented outside of conscious awareness. These findings were replicated and extended in a second experiment. In this experiment, emotion words presented outside of conscious awareness were responded faster by arm flexion when they were associated with approach than when they were associated with avoidance, irrespective of their valence. Conversely, emotion words associated with avoidance were responded faster by arm extension. Globally, these findings suggest that the implicit perception of affective stimuli automatically triggers the behavioral responses that are associated with them.
