Attentional bias towards happy faces in the dot-probe paradigm: it depends on which task is used.

Two recent articles [Gronchi et al., 2018. Automatic and controlled attentional orienting in the elderly: A dual-process view of the positivity effect. Acta Psychologica, 185, 229-234; Wirth & Wentura, 2020. It occurs after all: Attentional bias towards happy faces in the dot-probe task. Attention, Perception, & Psychophysics, 82(5), 2463-2481] report attentional biases for happy facial expressions in the dot-probe paradigm, albeit in different directions. While Wirth and Wentura report a bias towards happy expressions, Gronchi et al. found a reversed effect. A striking difference between the studies was the task performed by the participants. While in Wirth and Wentura, participants performed a discrimination task, they performed a location task in Gronchi et al. In Experiment 1, we directly compared the two versions of the dot-probe paradigm. With the discrimination task, the bias towards happy faces was replicated. However, the location task yielded a null effect. In Experiment 2, we found a cueing effect with an abrupt onset cue in both tasks. However, for the location task a congruence-sequence effect (a typical characteristic of response-priming processes) occurred. This result suggests that in the location task, attentional processes are confounded with response-priming processes. We recommend to generally use discrimination tasks.

Social processing modulates the initial allocation of attention towards angry faces: evidence from the N2pc component.

Previous research has shown that attentional bias towards angry faces is moderated by the activation of a social processing mode. More specifically, reliable cueing effects for angry face cues in the dot-probe task only occurred when participants performed a task that required social processing of the target stimuli. However, cueing effects are a rather distal measure of covert shifts in spatial attention. Thus, it remains unclear whether the social processing mode modulates initial allocation of attention to or attentional disengagement from angry faces. In the present study, we used the N2pc, an event-related potential component, as an index of attentional shifts towards angry faces. Participants performed a dot-probe task with two different target conditions while the electroencephalogram (EEG) was recorded. In the social target condition, target stimuli were socially meaningful (schematic faces), and in the non-social target condition, they were meaningless (scrambled schematic faces). The amplitude of the N2pc component elicited by angry face cues was significantly larger in the social target condition than in the non-social target condition. This pattern also occurred for behavioural cueing effects. These results suggest that the activation of a social processing mode due to current task demands affects the initial allocation of attention towards angry faces.

Emotional face expressions and group membership: Does affective mismatch induce conflict?

When asked to judge or react to a facial emotional display of a person, people do not only take the emotion into account, but also other socially important features of the face, such as, for example, ethnicity (Kozlik & Fischer, 2020; Paulus & Wentura, 2014). Importantly, the emotion-related and nonemotion-related features are seemingly not (or not always) processed in a simple, additive manner, but are-in a more functional manner-integrated to provide an "amalgamated signal" on which individuals base their judgment and responses. Whereas Paulus and Wentura (2014) put forward a social-message account of this amalgamated signal, Kozlik and Fischer (2020) recently proposed a processing-conflict explanation. The empirical evidence regarding this issue is, however, mixed. In three experiments, we aimed at replicating and extending Kozlik and Fischer's central experiment to gain further insight into the validity of the social-message versus the processing-conflict account. However, we failed to replicate their findings. The implications of the new evidence for the two accounts are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

The Functional Self.

Current research describes a particular component of the self-concept that influences a wide variety of cognitive processes while it depicts a rather basic component of the self-concept. However, this minimal self seems to be anything but simple; in fact, it seems to be highly functional. Based on previous findings on newly formed self-associations, we put the postulated functionality of this minimal self to another test by retesting its protection mechanisms against negative content. In a pilot experiment, we did not find an overall reduction of negative self-assignments against neutral self-assignments. However, the results indicated an initial difference (as hypothesized) between negative and neutral self-assignments, which decreases over the course of the experiment. We put this interactive effect of valence and block to test in our main experiment, which replicated the data pattern of the pilot experiment. In sum, the results indicate a mandatory integration of stimuli into the self-concept and also a reduction of the integration due to negative valence, thereby supporting a robust protection mechanism.

Assessing subjective prime awareness on a trial-by-trial basis interferes with masked semantic priming effects.

Ratings of perceptual experience on a trial-by-trial basis are increasingly used in masked priming studies to assess prime awareness. It is argued that such subjective ratings more adequately capture the content of phenomenal consciousness compared to the standard objective psychophysical measures obtained in a session after the priming experiment. However, the concurrent implementation of the ratings within the priming experiment might alter magnitude and processes underlying semantic priming, because participants try to identify the masked prime. In the present study, we therefore compared masked semantic priming effects assessed within the classical sequential procedure, in which prime identification is psychophysically assessed after the priming experiment, with those obtained in a condition, in which prime awareness is rated within the priming experiment. Two groups of participants performed a lexical decision task (LDT) on targets preceded by masked primes of 20, 40, or 60 ms durations, to induce the variability of prime awareness. One group additionally rated prime visibility trials-wise using the Perceptual Awareness Scale (PAS), whereas the other group only performed the LDT. Analysis of reaction times (RTs) as well as drift diffusion modeling revealed general priming effects on RT and drift rate only in the PAS-absent group. In the PAS-present group, residual priming effects on RT and the non-decisional component t0 were obtained for trials with rated prime awareness. This shows that assessing subjective perceptual experience on a trial-by-trial basis heavily interferes with semantic processes underlying masked priming, presumably due to attentional demands associated with concurrent prime identification.

When emotions cannot be efficiently used to guide attention: Flexible, goal-relevant utilization of facial emotions is hindered by social anxiety.

In order to achieve optimal outcomes in diverse situations, emotional information can be used to initiate novel, goal-directed processes that are not inherently related to the emotional meaning. Demonstrating this goal-dependent flexibility, in a recent study, we presented facial emotions as informative spatial cues: Participants could direct their attention to the probable target location based on the expressed emotion with a remarkable efficiency (Folyi, Rohr, & Wentura, 2020). However, as inherent motivational aspects of threat-related facial expressions can be particularly salient to socially anxious individuals (e.g., Staugaard, 2010), they might not be able to use this information flexibly in the pursuit of a context-specific goal. The present study tested this assumption in an endogenous cueing task with anger and fear expressions as informative central cues. Indeed, in Experiment 1 (N = 174), higher social anxiety was associated with reduced cueing at a 600 ms cue-target asynchrony, and this deficit was specific to social as opposed to general anxiety. Furthermore, this effect occurred only when faces were presented upright (Experiment 1), and not under inverted presentation (Experiment 2, N = 90), ruling out a general deficit in attentional control. The results suggest that flexible utilization of threat-related emotional information is sensitive to participants' social anxiety, suggesting an imbalance between using emotional information in the pursuit of a context-dependent goal on the one hand, and processes intrinsically related to the emotional meaning on the other.

Undeserved reward but not inevitable loss biases attention: Personal control moderates evaluative attentional biases in the additional-singleton paradigm.

It is important for organisms to notice signals of opportunities (i.e., chances for performance-dependent reward) and dangers (i.e., performance-dependent risks of loss). Attentional biases towards opportunity and danger signals should therefore be functionally valuable. By contrast, the functional value of attentional biases towards signals of performance-independent (i.e., uncontrollable) rewards or losses is not obvious. The present study compares attentional biases towards positive and negative stimuli, depending on whether the stimuli signal performance-dependent or performance-independent reward or loss. Specifically, we induced colour-valence associations before engaging participants in an additional-singleton task that measures attentional bias. In the valence-induction phase, one colour signalled a potential reward, and another colour signalled a potential loss; importantly, in one group, rewards and losses were performance-dependent, whereas in another group, they were performance-independent (i.e., seemingly random). In the subsequent additional-singleton task, we found increased additional-singleton effects for colours associated with performance-dependent rewards and losses (i.e., opportunities and dangers). If, however, rewards and losses were performance-independent, the singleton effect was enhanced only for reward but not loss stimuli.

Involuntary evaluation of others' emotional expressions depends on the expresser's group membership. Further evidence for the social message account from the extrinsic affective Simon task.

The social message account (SMA) hypothesizes that the evaluation of emotional facial expressions depends on the ethnicity of the expressers. For example, according to SMA, a happy face of a member of a prejudiced ethnicity is immediately interpreted as potentially malevolent. Evidence for this approach was found initially in evaluative priming (EP) and approach-avoidance tasks (AA) by showing an emotion × ethnicity interaction on positivity scores (EP) and approach scores (AA), respectively. Recently, attempts to replicate the EP results failed. Due to the inconclusive EP results, it was important to examine the influence of ethnicity on processing of emotional expression with another task testing involuntary evaluations. The extrinsic affective Simon task was used with stimuli varying on emotion (happy vs. fear) and ethnicity (White-Caucasian vs. Middle-Eastern men). This task was chosen because in contrast to EP (where faces are presented as task-irrelevant primes) faces are task-relevant. Experiment 1 yielded an emotion × ethnicity interaction with regard to positivity scores that fit SMA predictions. The results are also important in challenging a recent theoretical alternative to SMA, namely the processing conflict account. A generalization of the emotion × ethnicity pattern to learned arbitrary in- and out-groups (Experiment 2) failed, suggesting that involuntary processing of (task-irrelevant) group status depends on perceptual features.

Effects of evaluative homogeneity in working memory.

In four experiments, a change detection task using emotional (i.e., angry and happy) faces as stimuli was implemented to investigate the effects of evaluative congruency on working-memory performance and to replicate the angry-face benefit (i.e., better performance for angry compared to happy and neutral faces) found in former studies. Although results of the single experiments were heterogeneous, an overall analysis revealed better performance in trials with evaluatively congruent compared to evaluatively incongruent displays and an angry-face benefit. The congruency effect is in line with recent assumptions that evaluative-priming effects might arise from a mutual facilitation of simultaneously active evaluatively congruent concepts. Research on the angry-face benefit is enriched by the finding that the benefit was also found in control experiments using inverted faces. This result suggests that the effect is based on perceptual features of angry faces.

Social Message Account or Processing Conflict Account - Which Processes Trigger Approach/Avoidance Reaction to Emotional Expressions of In- and Out-Group Members?

Faces are characterized by the simultaneous presence of several evaluation-relevant features, for example, emotional expression and (prejudiced) ethnicity. The social message account (SMA) hypothesizes the immediate integration of emotion and ethnicity. According to SMA, happy in-group faces should be interpreted as benevolent, whereas happy out-group faces should be interpreted as potentially malevolent. By contrast, fearful in-group faces should be interpreted as signaling an unsafe environment, whereas fearful out-group faces should be interpreted as signaling inferiority. In contrast, the processing conflict account (PCA) assumes that each face conveys two rather independent evaluative features, emotion and ethnicity. Thus, stimuli might be either affectively congruent or incongruent, and thereby exert influences on behavior. The article reviews the evidence with regard to the two accounts before reporting an experiment that aims at disentangling them. In an approach/avoidance task (AAT), either happy/fearful faces of German and Turks were presented or happy/fearful faces of young and old persons. There are prejudices against Turk/Middle-eastern persons (in Germany) as well as against old persons. For SMA, the two prejudices are of different type; thus prediction for the AAT diverge for the two group conditions. In contrast, for PCA both group features (i.e., Turk ethnicity and old age) are negative features (in comparison to their counterparts) which are affectively congruent or incongruent to the emotional expression. Hence, the results pattern in the AAT should be comparable for the two group conditions. In accordance with SMA but in contrast to PCA, we found different patterns for the two group conditions.

How Emotion Relates to Language and Cognition, Seen Through the Lens of Evaluative Priming Paradigms.

Affect and emotion are essential aspects of human life. These states or feelings signal personally relevant things or situations and color our memories and thoughts. Within the area of affective or emotion processing, evaluation-the assessment of the valence associated with a stimulus or event (i.e., its positivity or negativity)-is considered a fundamental process, representing an early and crucial stage in constructivist emotion theories. Valence evaluation is assumed to occur automatically when encountering a stimulus. But does this really apply always, even if we simply see a word? And if so, what exactly is processed or activated in memory? One approach to investigating this evaluative process uses behavioral priming paradigms and, first and foremost, the evaluative priming paradigm and its variants. In the present review, we delineate the insights gained from this paradigm about the relation of affect and emotion to cognition and language. Specifically, we reviewed the empirical evidence base with regard to this issue as well as the proposed theoretical models of valence evaluation, specifically with regard to the nature of the representations activated via such paradigms. It will become clear that affect and emotion are foremost (and, perhaps, even exclusively) triggered by evaluative priming paradigms in the sense that semantic affective knowledge is activated. This knowledge should be modeled as being active in working memory rather than in long-term memory as was assumed in former models. The emerging evidence concerning the processing of more specific emotion aspects gives rise to the assumption that the activation of these semantic aspects is related to their social importance. In that sense, the fast and (conditionally) automatic activation of valence and other emotion aspects in evaluative priming paradigms reveals something about affect and emotion: Valence and specific emotion aspects are so important for our daily life that encountering almost any stimulus entails the automatic activation of the associated valence and other emotion aspects in memory, when the context requires it.

Emotion misattribution from complex scene pictures: Evidence for affective processing beyond valence.

The present experiments employed an emotion misattribution procedure to investigate if, and to what extent, emotional pictures are automatically processed on an emotion-specific level. We employed emotional pictures from the International Affective Picture System (Lang, Bradley, & Cuthbert, 2008) depicting joy-, anger-, fear-, and sadness-related contents as prime stimuli in the four-category emotion misattribution procedure (Rohr, Degner, & Wentura, 2015). Pictures were presented briefly and masked to avoid intentional responding. The pattern of results across all experiments provides evidence for an unfolding of emotion specificity along with the degree of visibility of primes. When presentation duration allowed for relatively good prime visibility (40 ms; Experiment 1), we observed emotion-specific misattribution effects for each prime category. With shorter prime presentation reducing prime visibility (30 ms; Experiment 2a and 2b), misattribution effects became less specific: While anger-related emotional scenes were clearly differentiated from fear and sadness-associated scenes, the latter two were not differentiated from one another. This pattern cannot be explained by simple semantic processing, but fits to an early appraisal of the coping ability associated with the emotion triggered by the pictorial content highlighting that specific, emotion-related processes are involved at the very early stages of emotional information processing.

Corrigendum: Degree and Complexity of Non-conscious Emotional Information Processing - A Review of Masked Priming Studies.

[This corrects the article DOI: 10.3389/fnhum.2021.689369.].

Degree and Complexity of Non-conscious Emotional Information Processing - A Review of Masked Priming Studies.

Whether and to what degree information can be processed non-consciously has been a matter of debate since the emergence of psychology as a science. Emotional information, in particular, has often been assumed to have a privileged status because of its relevance for well-being and survival (e.g., to detect a threat). Indeed, many studies have explored non-conscious processing of evaluative (i.e., "emotional" in a broad sense) or emotional (e.g., facial expressions) features using the "silver bullet" of non-consciousness research - the masked sequential priming paradigm. In its prototypical form, this paradigm involves the categorization of target stimuli according to valence (e.g., is the target positive or negative?). Each target is preceded by a briefly presented prime that is followed by a mask to constrain awareness. Non-conscious processing is inferred from subtle influences of the prime on target processing, that is, whether responses are faster if prime and target are valence-congruent or not. We will review this research with a focus on three questions: first, which methods are used in this area to establish non-conscious processing? Second, is there evidence for non-conscious extraction of evaluative information? Third, is there evidence for non-conscious processing beyond a simple valence (positive/negative) discrimination, for example, processing of emotion-specific information? We will highlight important current debates and potential directions in which the field will move in the future.

Creating a network of importance: The particular effects of self-relevance on stimulus processing.

Several factors guide our attention and the way we process our surroundings. In that regard, there is an ongoing debate about the way we are influenced by stimuli that have a particular self-relevance for us. Recent findings suggest that self-relevance does not always capture our attention automatically. Instead, an interpretation of the literature might be that self-relevance serves as an associative advantage facilitating the integration of relevant stimuli into the self-concept. We compared the effect of self-relevant stimuli with the effect of negative stimuli in three tasks measuring different aspects of cognitive processing. We found a first dissociation suggesting that negative valence attracts attention while self-relevance does not, a second dissociation suggesting that self-relevance influences stimulus processing beyond attention-grabbing mechanisms and in the form of an "associative glue," while negative valence does not, and, last but not least, a third dissociation suggesting that self-relevance influences stimulus processing at a later stage than negative valence does.

It occurs after all: Attentional bias towards happy faces in the dot-probe task.

Many studies have shown that not only threatening but also positive stimuli capture visual attention. However, in the dot-probe task, a common paradigm to assess attention to emotional stimuli, usually no bias towards happy faces occurs. Here, we investigated whether such a bias can occur and, if so, under which conditions. In Experiment 1, we investigated whether the bias is contingent on the simultaneous presentation of distractor stimuli with the targets. Participants performed a dot-probe task with either stand-alone targets or targets that were accompanied by distractors. We found an attentional bias towards happy faces that was not moderated by target type. To rule out perceptual low-level confounds as the cause of the bias towards happy faces, Experiments 2a and 2b comprised dot-probe tasks with inverted face cues. No attentional bias towards inverted happy faces occurred. In Experiment 3, we investigated whether a bias towards happy faces is contingent on a social-processing mode. Participants performed a dot-probe task with socially meaningful (schematic faces) or socially meaningless (scrambled schematic faces) targets. Again, a bias towards happy faces, which was not moderated by target type, occurred. In Experiment 4, we investigated the attentional bias towards happy faces when another highly relevant expression was present. Participants performed a dot-probe task with both happy and angry face cues. A significant attentional bias towards emotional faces occurred that did not differ between both cue emotions. These results suggest that happy faces are sufficiently relevant for observers to capture attention in the dot-probe task.

When emotions guide your attention in line with a context-specific goal: Rapid utilization of visible and masked emotional faces for anticipatory attentional orienting.

The emotional value of a stimulus influences how the stimulus itself is perceived, and can "automatically" give rise to processes whose characteristics are inherently related to the emotional content of the stimuli (e.g., emotion-specific action tendencies). However, to provide optimal contextual flexibility, we propose that emotional information can be utilized in an "automatic" manner for novel, goal-directed processes that are not inherently signaled by the emotional meaning of the stimulus. We investigated this question using the endogenous cueing paradigm: Specifically, we asked how rapidly, efficiently, and to what degree of specificity emotional expressions can be utilized to anticipate the location of targets. We tested the specificity of the utilized emotional information by presenting emotional faces with contrasting affective valence (i.e., joy and anger) or pairs of negative expressions (e.g., anger and fear) as informative central cues. By presenting both masked and visible face cues, we tested whether and to what degree of specificity facial expressions can be utilized to orient attention under conditions of limited cue awareness. Cue validity effects emerged consistently in all experiments, and cuing effects built up fast, already at 300 ms cue-target asynchrony, and-at least partly-on the basis of holistic face representation. These results indicate that emotional faces can be utilized in line with a context-specific goal, with high specificity, rapidly, and even on the basis of limited perceptual input, suggesting that the utilization of emotional information can combine remarkable efficiency and situational flexibility in order to achieve optimal outcomes in various critical situations.

Manipulating the depth of processing reveals the relevance of second eye fixations for recollection but not familiarity.

It is well known that memory affects eye movements. However, the role of individual eye fixations for recognition memory processes has hardly been investigated. Recent findings show that second fixations are especially relevant for recollection, a process associated with the retrieval of context information, but less for recognition based solely on item familiarity. The aim of the present study was to overcome limitations of a previous study (Schwedes and Wentura in Memory, 2019. https://doi.org/10.1080/09658211.2019.1567789 ) and to provide further evidence that second fixations are especially relevant for recollection-based recognition. Whereas recollection- and familiarity-based recognition was an unconstrained quasi-experimental variable in a previous study, here we manipulated the depth of stimulus processing in the encoding phase to experimentally manipulate the probability of subsequent item recollection. In the old/new recognition memory test, presentation of test probes was terminated after one or two stimulus fixations. "Old" responses in the recognition test were followed by a remember/know/guess procedure to assess recollection-based versus familiarity-based recognition. We found the expected depth of processing effect, with better recognition and more recollection-based responses after deep encoding. This effect, however, was significantly larger if two fixations instead of just one were allowed. There were no corresponding effects for familiarity-based recognition. Thus, a second fixation seems to play an important role only for recollection-based recognition.

The natural egocenter: An experimental account of locating the self.

A lot of research suggests that people have an understanding of what they consider their 'self' and where it is located, namely near the head and upper torso. We assess whether these interpretations of the location of the self, which are based on subjective ratings, can be confirmed with an objective measure. Therefore, we used a paradigm in which neutral stimuli are associated with the self and a prioritization of the newly self-associated stimuli is interpreted as an integration of the stimuli into the self. Remarkably, only when the to-be-associated stimuli were presented close to the head and upper torso they were integrated and prioritized, but not when the stimuli were presented far away from these regions. The results indicate an influence of the distance between to-be-associated stimuli and the head/upper torso, thereby suggesting an implicit location of the self in this area, which does not depend on external beliefs.

Involuntary sensory enhancement of gain- and loss-associated tones: A general relevance principle.

In a recent event-related potential (ERP) study (Folyi et al., 2016), we have demonstrated that sensory processing of task-irrelevant tones is enhanced when they were previously associated with positive or negative (by the means of monetary gains and losses, respectively) affective meaning relative to tones with neutral meaning, as indexed by the enhancement of the auditory N1-amplitude. In the present study, (1) in line with the hypothesis of affective counter-regulation, we investigated whether positive versus negative tones can receive differential attentional enhancement, depending on motivational context (Experiment 1); and (2) whether the early facilitation of positive and negative tones can operate strictly outside of the focus of voluntary attention (Experiment 2). In Experiment 1, we replicated the basic N1 valence effect, but found no moderation by motivational context. In Experiment 2, we found a small valence effect on the N1. By combining data from the three experiments (i.e., our previous experiment and the present ones; N = 72), we found a clear enhancement of N1-amplitudes for valenced tones without moderation by experiment. This pattern of results suggests comparable early attentional enhancement of valenced tones in general: (a) despite different level of concurrent task-relevant attentional and motivational demands in these experiments; and (b) without prioritizing one valence category over another, supporting our claim that the general relevance of the tones with high motivational value that governs early attentional facilitation.
