Abstract
Uncertainty is unavoidable, and maladaptive responses to uncertainty may underlie the etiology and maintenance of psychopathology. A general tendency to associate uncertainty with aversive consequences, a type of covariation bias, can amplify aversive emotional experiences. To address questions about uncertainty during emotion regulation, we examined the Late Positive Potential (LPP) - an electrocortical marker of attention to and appraisal of motivationally relevant emotional stimuli - during a task designed to measure the effect of covariation bias and its emotional response consequences. Event-related potentials (ERPs) were recorded while participants (N = 52) were presented with a pre-stimulus cue that either conveyed information about the valence of an upcoming emotional image, or left them in ambiguity. We replicated findings that demonstrate expectancy biases in a priori and online expectancies of emotion-eliciting images, as well as in a posteriori estimates for concurrence of uncertainty cues and aversive images. Moreover, we demonstrate a novel finding that uncertainty cues amplify the LPP in response to subsequent aversive emotional stimuli. These findings advance research by conjoining existing emotion regulation research on the LPP with study of the effects of uncertainty on emotional appraisal and highlight the importance of accounting for stimulus uncertainty in emotion regulation research.

Acta Psychol (Amst) 2024; 243:104150.

Abstract
Numerous studies have demonstrated that attention is quickly oriented towards threatening stimuli, and that this attentional bias is difficult to inhibit. The root cause(s) of this bias may be attributable to the affective (e.g., valence) or visual features (e.g., shape) of threats. In two experiments (behavioral, eye-tracking), we tested which features play a bigger role in the salience of threats. In both experiments, participants looked for a neutral target (butterfly, lock) among other neutral objects. In half of the trials a threatening (snake, gun) or nonthreatening (but visually similar; worm, hairdryer) task-irrelevant distractor was also present at a near or far distance from the target. Behavioral results indicate that both distractor types interfered with task performance. Rejecting nonthreatening distractors as nontargets was easier when they were presented further from the target but distance had no effect when the distractor was threatening. Eye-tracking results showed that participants fixated less often (and for less time) on threatening compared to nonthreatening distractors. They also viewed targets for less time when a threatening distractor was present (compared to nonthreatening). Results suggest that visual features of threats are easier to suppress than affective features, and the latter may have a stronger role in eliciting attentional biases.

Abstract
Responses to potentially dangerous stimuli are among the most basic animal behaviors. While research has shown that threats automatically capture the attention of human participants, research has failed to demonstrate automatic behavioral responses to threats in humans. Using a novel naturalistic paradigm, we show that two species of animals humans often report fearing trigger rapid withdrawal responses: participants withdrew their arm from photos of snakes and spiders faster, and with higher acceleration when compared to bird and butterfly stimuli. The behavior was specific to withdrawal as approach movements or button-press/release tasks failed to detect a similar difference. Moreover, between-participant differences in how aversive they found the stimuli predicted the participant's withdrawal speed, indicating that the paradigm was also sensitive to trait-level differences between individuals. Using electroencephalography (EEG), we show that the fast withdrawal was mediated by two attentional processes. First, fast withdrawal responses were associated with early amplification of sensory signals (40-110 ms after stimulus). Second, a later correlate of feature-based attention (early posterior negativity, EPN, 200-240 ms after stimulus) revealed the opposite pattern: Stronger EPN was associated with slower behavioral responses, suggesting that the deployment of attention towards the threatening stimulus features, or failure to "disengage" attention from the stimulus, was detrimental for withdrawal speed. Altogether, the results suggest that rapid behavioral withdrawal from a threatening animal is mediated by reflex-like attentional processing, and later, conscious attention to stimulus features may hinder escaping the treat.

Abstract
The quality of the defensive response to a threat depends on the elements that trigger the fear response. The current classification system of phobias does not account for this. Here, we analyze the fear-eliciting elements and discern the different types of fears that originate from them. We propose Pain, Disgust, Vasovagal response, Visual-vestibular and postural interactions, Movement and Speed, Distance and Size, Low and mid-level visual features, Smell, and Territory and social status. We subdivide phobias according to the fear-eliciting elements most frequently triggered by them and their impact on behavior. We discuss the implications of a clinical conceptualization of phobias in humans by reconsidering the current nosology. This conceptualization will facilitate finding etiological factors in defensive behavior expression, fine-tuning exposure techniques, and challenging preconceived notions of preparedness. This approach to phobias leads to surprising discoveries and shows how specific responses bear little relation to the interpretation we might later give to them. Dividing fears into their potentially fear-eliciting elements can also help in applying the research principles formulated by the Research Domain Criteria initiative.

Abstract
Human visual attention is biased to rapidly detect threats in the environment so that our nervous system can initiate quick reactions. The processes underlying threat detection (and how they operate under cognitive load), however, are still poorly understood. Thus, we sought to test the impact of task-irrelevant threatening stimuli on the salience network and executive control of attention during low and high cognitive load. Participants were exposed to neutral or threatening pictures (with moderate and high arousal levels) as task-irrelevant distractors in near (parafoveal) and far (peripheral) positions while searching for numbers in ascending order in a matrix array. We measured reaction times and recorded eye-movements. Our results showed that task-irrelevant distractors primarily influenced behavioural measures during high cognitive load. The distracting effect of threatening images with moderate arousal level slowed reaction times for finding the first number. However, this slowing was offset by high arousal threatening stimuli, leading to overall shorter search times. Eye-tracking measures showed that participants fixated threatening pictures more later and for shorter durations compared to neutral images. Together, our results indicate a complex relationship between threats and attention that results not in a unitary bias but in a sequence of effects that unfold over time.

Abstract
Recent work has revealed that social support cues are powerful inhibitors of the fear response. They are endowed with a unique combination of inhibitory properties, enabling them to both inhibit fear in the short term and reduce fear in the long term. While these findings had previously been thought to suggest that social support cues belong to a category of prepared safety stimuli, mounting evidence clearly shows that the mechanisms underlying safety signaling cannot account for the unique effects of social support cues. Here, we propose a reclassification of social support cues as members of a prepared fear suppressor category. We present an argument for the prepared fear suppressor classification, discuss potential mechanisms underlying the unique effects of prepared fear suppressors, and outline next steps to build an understanding of this category and its clinical implications. This review is meant to serve as a roadmap for exploring this novel category of prepared fear suppressors, whose never-before-seen range of inhibitory effects makes them an important and impactful discovery with implications for both fear learning theory and clinical application.

Abstract
It has been posited (Öhman, 1986) that the processing of threatening stimuli became prioritized during the course of mammalian evolution and that such objects may still enjoy an advantage in visual processing to this day. It has been well-documented that both mid-level visual features (i.e., conjunctions of low-level features) and the arousal level of threatening stimuli affect attentional allocation (Cisler & Koster, 2010; Wolfe & Horowitz, 2004). Despite this, few studies have investigated the effect these factors have on visual working memory resources. Here, we investigated these factors using a rapid serial visual presentation (RSVP) paradigm, and by manipulating mid-level features (specifically, shape: similar vs. dissimilar) and the arousal level (non-threatening vs threatening) of the stimuli. Participants watched an RSVP stream in preparation for an upcoming memory test. Then, they completed a two-alternative forced-choice recognition memory test (with semantically matched foils) wherein they had to identify which item they had seen in the RSVP stream. Our results showed that when shape was a sufficient feature to discriminate the target from the other items in the stream, there was no effect of arousal (i.e., threat level) on reaction time or accuracy during the memory test. However, when the shapes of all the stimuli in the visual stream were highly similar, an effect of arousal appeared: When the target had a different arousal level than the background items (i.e., non-targets), performance was improved. Together, the results suggest that both mid-level visual features and arousal level can modulate competition for visual working memory resources.

Abstract
AbstractChildren’s nighttime fear is hypothesized as a cognitive relict reflecting a long history of natural selection for anticipating the direction of nighttime predatory attacks on the presumed human ancestor, Australopithecus afarensis, whose small-bodied females nesting in trees would have anticipated predatory attacks from below. Heavier males nesting on the ground would have anticipated nighttime predatory attacks from their sides. Previous research on preschool children and adults supports this cognitive-relict hypothesis by showing developmental consistencies in their remembrances of the location of a “scary thing” relative to their beds. The current study expands this research by investigating whether nighttime fear in childhood, including the effect of parental threats to behave, influenced adult spatial fears in different biotic and abiotic situations. A 25-item questionnaire employing ordinal scales was given to 474 foreign-born Vietnamese and ethnic Chinese adults living in the USA. Univariate analyses of adult remembrances of childhood indicated that females were more fearful of something scary below their beds than males. To examine the influence of childhood nighttime fear on adult fears, exploratory factor analyses supported three factors: (1) indeterminate agents, indicated something scary under the bed, the difficulty locating unspecific threats, and the brief appearances of large apparitions; (2) environmental uncertainty, indicated by potential encounters with unseen animate threats; (3) predictable animals, as the relative comfort of viewing animals in zoo exhibits. Using structural equation modeling, the results suggest that childhood nighttime fear influenced only the latent variable, indeterminate agents, in both groups via the mediating variable, parental threats.

Abstract
Supernatural fears, although common, are not as well-understood as natural fears and phobias (e.g., social, blood, and animal phobias) which are prepared by evolution, such that they are easily acquired through direct experience and relatively immune to cognitive mediation. In contrast, supernatural fears do not involve direct experience but seem to be related to sensory or cognitive biases in the interpretation of stimuli as well as culturally driven cognitions and beliefs. In this multidisciplinary synthesis and collaborative review, we claim that supernatural beliefs are "super natural." That is, they occur spontaneously and are easy to acquire, possibly because such beliefs rest on intuitive concepts such as mind-body dualism and animism, and may inspire fear in believers as well as non-believers. As suggested by psychological and neuroscientific evidence, they tap into an evolutionarily prepared fear of potential impending dangers or unknown objects and have their roots in "prepared fears" as well as "cognitively prepared beliefs," making fear of supernatural agents a fruitful research avenue for social, anthropological, and psychological inquires.

Abstract
In allergic conditions, trigger identification is often inaccurate, and may be influenced by pre-existing beliefs. In this study, we investigated the acquisition and generalization of symptom trigger beliefs in individuals with allergic rhinitis (n = 24) and control participants (n = 24). In a lab-based trigger acquisition task, unique exemplars of two trigger categories were either paired with saline inhalation (CS- category) or citric acid inhalation (CS+ category). The next day, we tested recognition and symptom expectancy for CS category exemplars and exemplars of novel trigger categories. Participants acquired differential symptom expectancies for CS+ compared to CS- exemplars, with faster acquisition in participants with rhinitis. Differential symptom expectancies persisted the next day, and generalized to novel trigger categories, with stronger generalization in rhinitis vs. control participants. These patterns of acquisition and generalization suggest that overgeneralization of trigger beliefs may complicate trigger identification in participants with allergic conditions.

Abstract
Across three experiments, we investigated whether electrodermal responses conditioned to ontogenetic fear-relevant (pointed guns) and phylogenetic fear-relevant stimuli (snakes and spiders) would resist instructed extinction in a within-participant differential fear conditioning paradigm. Instructed extinction involves informing participants before extinction that the unconditional stimulus (US) will no longer be presented. This manipulation has been shown to abolish fear conditioned to fear-irrelevant conditional stimuli, but is said to leave fear conditioned to images of snakes and spiders intact. The latter finding, however, has only been demonstrated when fear-relevance is manipulated between-groups. It is also not known whether instructed extinction affects fear conditioned to ontogenetic fear-relevant stimuli, such as pointed guns. In Experiment 1, we demonstrated that fear conditioned to images of pointed guns does not resist instructed extinction. In Experiment 2, we detected some evidence to suggest that fear conditioned to images of snakes and spiders survives instructed extinction but this evidence was not conclusive. In Experiment 3, we directly compared the effects of instructed extinction on fear conditioned to snakes and spiders and to guns and provide strong evidence that fear conditioned to both classes of stimuli is reduced after instructed extinction with no differences between ontogenetic and phylogenetic stimuli. The current results suggest that when fear relevance is manipulated within-participants fear conditioned to both phylogenetic and ontogenetic, fear-relevant stimuli responds to instructed extinction providing evidence in favor of a socio-cultural explanation for "preparedness" effects.

Abstract
Although large body of research has demonstrated the attention-grabbing nature of threat-related stimuli, threat could also facilitate attentional processes. Previous studies suggest a linear relationship between the facilitating effect of the arousal level conveyed by threat and performance on visual search tasks. Due to the temporal competition bias favouring stimuli with higher arousal level, this could be more pronounced for shorter onset times. Here, through two experiments we aimed to disentangle the two effects by using a visual search paradigm that allowed us to separate the emotional stimuli and the cognitive task. We manipulated stimulus onset time and threat intensity. Participants saw neutral and threatening pictures as priming stimuli, and then, they had to find numbers in ascending order in a matrix array. We measured the reaction time for finding the first number, and search time for finding all the numbers. Our results showed that when the priming stimulus is presented, longer threatening pictures produced longer reaction times compared to neutral ones, which was reversed with increase in arousal. We did not find any significant effects for the shorter onset time. Further theoretical and methodological implications are discussed.

Abstract
Since Seligman (1971) statement that the vast majority of phobias are about objects essential to the survival of a species, a multitude of laboratory studies followed, supporting the finding that humans learn to fear and detect snakes (and other animals) faster than other stimuli. Most of these studies used schematic drawings, images, or pictures of snakes, and only a small amount of fieldwork in naturalistic environments was done. We address fear preparedness theories and automatic fast detection data from mainstream laboratory data and compare it with ethobehavioral information relative to snakes, predator-prey interaction, and snakes' defensive kinematics strikes in order to analyze their potential matching. From this analysis, four main findings arose, namely that (1) snakebites occur when people are very close to the snake and are unaware or unable to escape the bite; (2) human visual detection and escape response is slow compared to the speed of snake strikes; (3) in natural environments, snake experts are often unable to see snakes existing nearby; (4) animate objects in general capture more attention over other stimuli and dangerous, but recent objects in evolutionary terms are also able to be detected fast. The issues mentioned above pose several challenges to evolutionary psychology-based theories expecting to find special-purpose neural modules. The older selective habituation hypothesis (Schleidt, 1961) that prey animals start with a rather general predator image from which specific harmless cues are removed by habituation might deserve reconsideration.

Abstract
A growing body of research has implicated disgust in various psychopathologies, especially anxiety-related disorders. Although the observed role of disgust in many disorders is robust, the mechanisms that may explain this role are unclear. Cutting-edge research in cognitive science has the potential to elucidate such mechanisms and consequently improve our understanding of how disgust contributes to the etiology and maintenance of psychopathology. In this qualitative review, we systematically assess cognitive bias mechanisms that have been linked to disgust and its disorders. This review suggests that disgust-related biases may be observed in memory, interpretation, judgment of expectancies, and attention, as well as at implicit levels. Of these cognitive domains, the most robust bias appears to be observed at the level of attention. However, reliable moderators of attentional biases for disgust have not yet been identified, and this bias has not been systematically linked to other levels of analysis. Despite these limitations, the available research indicates that attentional avoidance rather than orienting or maintenance may be the most characteristic of disgust. Attentional avoidance of disgust may have important implications for etiological and treatment models of disorders characterized by excessive disgust reactions. The implications for advancing such models are discussed in the context of a combined cognitive bias hypothesis.

Investigating evolutionary constraints on the detection of threatening stimuli in preschool children. Acta Psychol (Amst) 2018; 185:166-171.

Abstract
Numerous objects and animals could be threatening, and thus, children learn to avoid them early. Spiders and syringes are among the most common targets of fears and phobias of the modern word. However, they are of different origins: while the former is evolutionary relevant, the latter is not. We sought to investigate the underlying mechanisms that make the quick detection of such stimuli possible and enable the impulse to avoid them in the future. The respective categories of threatening and non-threatening targets were similar in shape, while low-level visual features were controlled. Our results showed that children found threatening cues faster, irrespective of the evolutionary age of the cues. However, they detected non-threatening evolutionary targets faster than non-evolutionary ones. We suggest that the underlying mechanism may be different: general feature detection can account for finding evolutionary threatening cues quickly, while specific features detection is more appropriate for modern threatening stimuli.

Abstract
Danger is a fundamental aspect of the lives of most animals. Adaptive behavior therefore requires avoiding actions, objects, and environments associated with danger. Previous research has shown that humans and non-human animals can avoid such dangers through two types of behavioral adaptions, (i) genetic preparedness to avoid certain stimuli or actions, and (ii) social learning. These adaptive mechanisms reduce the fitness costs associated with danger but still allow flexible behavior. Despite the empirical prevalence and importance of both these mechanisms, it is unclear when they evolve and how they interact. We used evolutionary agent-based simulations, incorporating empirically based learning mechanisms, to clarify if preparedness and social learning typically both evolve in dangerous environments, and if these mechanisms generally interact synergistically or antagonistically. Our simulations showed that preparedness and social learning often co-evolve because they provide complimentary benefits: genetic preparedness reduced foraging efficiency, but resulted in a higher rate of survival in dangerous environments, while social learning generally came to dominate the population, especially when the environment was stochastic. However, even in this case, genetic preparedness reliably evolved. Broadly, our results indicate that the relationship between preparedness and social learning is important as it can result in trade-offs between behavioral flexibility and safety, which can lead to seemingly suboptimal behavior if the evolutionary environment of the organism is not taken into account.

Abstract
Fearful individuals often overestimate the relationship between fear-relevant stimuli and aversive consequences. Such fear-relevant illusory correlations (ICs) might be involved in the maintenance of anxiety disorders. In this literature review, we found clear evidence that ICs are present and enhanced in fear of animals. We also revealed some evidence for ICs related to fear of flying, social anxiety, contamination fear, panic disorder, and post-traumatic stress disorder, but with considerably less clarity. Fear-relevant ICs seem to be best explained by both a priori expectancies and biased encoding of the experienced associations. Studies to date suggest that one important biased encoding process is the enhanced aversiveness/salience of fear-relevant outcomes. Future studies may improve insight by developing more reliable IC measures and testing the effect of encoding processes on treatment outcomes.

Abstract
Healthy individuals often exhibit prioritized processing of aversive information, as manifested in enhanced orientation of attention to threatening stimuli compared with neutral items. In contrast to this adaptive behavior, anxious, fearful, and phobic individuals show exaggerated attention biases to threat. In addition, they overestimate the likelihood of encountering their feared stimulus and the severity of the consequences; both are examples of expectancy biases. The co-occurrence of attention and expectancy biases in fear and anxiety raises the question about causal influences. Herein, we summarize findings related to expectancy biases in fear and anxiety, and their association with attention biases. We suggest that evidence calls for more comprehensive research strategies in the investigation of mutual influences between expectancy and attention biases, as well as their combined effects on fear and anxiety. Moreover, both types of bias need to be related to other types of distorted information processing commonly observed in fear and anxiety (e.g., memory and interpretation biases). Finally, we propose new research directions that may be worth considering in developing more effective treatments for anxiety disorders.

Abstract
We review issues associated with the phenomenology, etiology, assessment, and treatment of specific phobias in children and adolescents and provide suggestions for future research and clinical practice. In doing so, we highlight the early case studies of Little Hans and Little Albert and the advances that have been made following the publication of these seminal cases. In recent years, we have witnessed a deeper understanding of the etiology of specific phobias and developed a rich array of evidence-based assessments and treatments with which to address specific phobias in youth. Although much has been accomplished in this area of inquiry, we also note that much remains to be done before we can advance more fully our understanding, assessment, and treatment of specific phobias in youth. It will be important for future work to build more firmly on these developments and to better determine the moderators and mediators of change with our evidence-based treatments and to more vigorously pursue their dissemination in real-word settings.

Abstract
Inquiry into evolutionary adaptations has flourished since the modern synthesis of evolutionary biology. Comparative methods, genetic techniques, and various experimental and modeling approaches are used to test adaptive hypotheses. In psychology, the concept of adaptation is broadly applied and is central to comparative psychology and cognition. The concept of an adaptive specialization of learning is a proposed account for exceptions to general learning processes, as seen in studies of Pavlovian conditioning of taste aversions, sexual responses, and fear. The evidence generally consists of selective associations forming between biologically relevant conditioned and unconditioned stimuli, with conditioned responses differing in magnitude, persistence, or other measures relative to non-biologically relevant stimuli. Selective associations for biologically relevant stimuli may suggest adaptive specializations of learning, but do not necessarily confirm adaptive hypotheses as conceived of in evolutionary biology. Exceptions to general learning processes do not necessarily default to an adaptive specialization explanation, even if experimental results "make biological sense". This paper examines the degree to which hypotheses of adaptive specializations of learning in sexual and fear response systems have been tested using methodologies developed in evolutionary biology (e.g., comparative methods, quantitative and molecular genetics, survival experiments). A broader aim is to offer perspectives from evolutionary biology for testing adaptive hypotheses in psychological science.

Abstract
Anxiety disorder patients were repeatedly found to overestimate the association between disorder-relevant stimuli and aversive outcomes despite random contingencies. Such an illusory correlation (IC) might play an important role in the return of fear after extinction learning; yet, little is known about how this cognitive bias emerges in the brain. In a functional magnetic resonance imaging study, 18 female patients with spider phobia and 18 healthy controls were exposed to pictures of spiders, mushrooms and puppies followed randomly by either a painful electrical shock or nothing. In advance, both patients and healthy controls expected more shocks after spider pictures. Importantly, only patients with spider phobia continued to overestimate this association after the experiment. The strength of this IC was predicted by increased outcome aversiveness ratings and primary sensory motor cortex activity in response to the shock after spider pictures. Moreover, increased activation of the left dorsolateral prefrontal cortex (dlPFC) to spider pictures predicted the IC. These results support the theory that phobia-relevant stimuli amplify unpleasantness and sensory motor representations of aversive stimuli, which in turn may promote their overestimation. Hyper-activity in dlPFC possibly reflects a pre-occupation of executive resources with phobia-relevant stimuli, thus complicating the accurate monitoring of objective contingencies and the unlearning of fear.

Abstract
Adequate asthma management depends on an accurate identification of asthma triggers. A review of the literature on trigger perception in asthma shows that individuals vary in their perception of asthma triggers and that the correlation between self-reported asthma triggers and allergy tests is only modest. In this article, we provide an overview of psychological mechanisms involved in the process of asthma triggers identification. We identify sources of errors in trigger identification and targets for behavioural interventions that aim to improve the accuracy of asthma trigger identification and thereby enhance asthma control.

Abstract
Whereas research has demonstrated that phobic or fearful individuals overestimate the likelihood of incurring aversive consequences from an encounter with feared stimuli, it has not yet been systematically investigated whether these individuals also overestimate the likelihood (i.e., the frequency) of such encounters. In the current study, spider-fearful and control participants were presented with background information that allowed them to estimate the overall likelihood that different kinds of animals (spiders, snakes, or birds) would be encountered. Spider-fearful participants systematically overestimated the likelihood of encountering a spider with respect to the likelihood of encountering a snake or a bird. No such expectancy bias was observed in control participants. The results thus strengthen our idea that there indeed exist two different types of expectancy bias in high fear and phobia that can be related to different components of the fear response. A conscientious distinction and examination of these two types of expectancy bias are of potential interest for therapeutic applications.

Abstract
Fears are quick and adaptive responses that permit powerful reply to imminent threats. Less adaptive, phobias are extreme manifestations of fear to objects or situations in the absence of a proportional danger. Although the utility of fear is accepted, the nature of phobias is controversial. Initial theories favored a fear conditioning-based explanation, with vicarious and information learning pathways subsequently included as additional routes to the development of specific phobias. More recently, an important group of investigations strengthened the case for a nonassociative account of fear acquisition proposing that evolutionarily relevant fears can occur without any need of critical learning experiences. In parallel, there is some evidence for a dedicated fear module in the detection of threats, involving the amygdala, which is relatively independent from conscious cognitive control. Nonetheless, cognitive models stress learning and developmental factors and their role in the etiology and maintenance of phobic behavior. This article critically reviews each of these views and theories stressing their recent developments, weaknesses, and controversies with an aim to provide the groundwork for the construction of a more integrated position. Finally, the authors suggest encouraging trends in recent research.

Abstract
Inaccurate perception of respiratory symptoms is often found in asthma patients. Typically, patients who inaccurately perceive asthma symptoms are divided into underperceivers and overperceivers. In this paper we point out that this division is problematic. We argue that little evidence exists for a trait-like stability of under- and overperception and that accuracy of respiratory symptom perception is highly variable within persons and strongly influenced by contextual information. Particularly, expectancy and affective cues appear to have a powerful influence on symptom accuracy. Based on these findings and incorporating recent work on associative learning, attention and mental representations in anxiety and symptom perception, we propose a cognitive-affective model of symptom perception in asthma. The model can act as a framework to understand both normal perception as well as under- and overperception of asthma symptoms and can guide the development of affect-related interventions to improve perceptual accuracy, asthma control and quality of life in asthma patients.

Abstract
The research aimed at examining attentional selectivity in a visual search paradigm using pictures of animals that have provided a recurrent threat in an evolutionary perspective (i.e., snakes and spiders) and pictures of animals that have supposedly posed no such threat (i.e., cats and fish). Experiment 1 showed no advantage of fear-relevant stimuli over non-fear-relevant animal stimuli. However, an attentional capture seemed to emerge as a delay in the disengagement of attention, specifically when there was a massive presentation of fear-relevant stimuli in the array. The results from Experiment 2, where participants were selected based specifically on their fear of either snakes or spiders (but not both), showed a preferential processing of the congruent feared stimulus, when compared with non-fearful participants, which strengthens the notion that fear significance may be an important factor drawing attention to a particular spatial location.

Abstract
Forty years on from the initial idea that fears could be learnt vicariously through observing other people's responses to a situation or stimulus, this review looks at the evidence for this theory as an explanatory model of clinical fear. First, we review early experimental evidence that fears can be learnt vicariously before turning to the evidence from both primate and human research that clinical fears can be acquired in this way. Finally, we review recent evidence from research on non-anxious children. Throughout the review we highlight problems and areas for future research. We conclude by exploring the likely underlying mechanisms in the vicarious learning of fear and the resulting clinical implications.

Abstract
Terror management theory (TMT) posits that cultural worldviews and self-esteem function to buffer humans from mortality-related anxiety. TMT research has shown that important behaviors are influenced by mortality salience (MS) even when they have no obvious connection to death. However, there has been no attempt to investigate TMT processes in anxious responding. The present research examines that question. In Study 1, compared to a control condition, MS increased anxious responding to spider-related stimuli, but only for participants who met criteria for specific phobia. In Study 2, compared to an aversive control condition, MS increased time spent washing hands, but only for those scoring high on a measure of compulsive hand washing (CHW). In Study 3, compared to a different aversive control condition, MS increased avoidance of a social interaction, but only for those scoring high on a measure of social interaction anxiety. The relevance of TMT in anxious responding is discussed.

Abstract
Affect and cognition have long been treated as independent entities, but in the current review we suggest that affect and cognition are in fact highly interdependent. We open the article by discussing three classic views for the independence of affect. These are (i) the affective independence hypothesis, that emotion is processed independently from cognition, (ii) the affective primacy hypothesis, that evaluative processing precedes semantic processing, and (iii) the affective automaticity hypothesis, that affectively potent stimuli commandeer attention and evaluation is automatic. We argue that affect is not independent from cognition, that affect is not primary to cognition, nor is affect automatically elicited. The second half of the paper discusses several instances of how affect influences cognition. We review experiments showing affective involvement in perception, semantic activation, and attitude activation. We conclude that one function of affect is to regulate cognitive processing.

Abstract
RésuméDans ce texte, nous proposons un cadre, qui vise à intégrer les contributions des approches constructionnistes et biologiques dans un domaine précis, celui des maladies mentales. Pour ce faire, nous utiliserons quelques propositions récentes faites par des philosophes de la biologie — plus spécifiquement les idées avancées par les tenants de la « théorie des systèmes développementaux » (TSD dans ce qui suit ; Griffiths et Gray, 1994 ; Griffiths et Stoltz, 2000 ; Oyama, 1999) ainsi que la notion d’« enracinement génératif » (generative entrenchment ; Wimsatt, 1986, 1999, 2000).

Abstract
Discriminative fear learning and fear generalization were examined in animal-fearful individuals and in control participants. Electrical shocks were administered contingent upon discriminative pictures of spiders or snakes, respectively, in a generalization-after-discrimination paradigm. Neither discriminative fear learning nor extinction was affected by the individual fear status of the animal categories. Novel feared stimuli, which resembled discriminative stimuli, were treated as more shock predictive than novel non-feared stimuli during generalization testing. Neither preparedness theory nor selective sensitization theory was capable to account for these observations. The findings are commensurable with the hypothesis that phobic fear interferes with the retrieval of memory traces.

Abstract
Zusammenfassung. Theoretischer Hintergrund: Die Unzulänglichkeiten traditioneller Konditionierungsmodelle zur Erklärung der Pathogenese von Angststörungen erfordern eine Erweiterung der lerntheoretischen Erklärungsansätze. Fragestellung: Untersucht wird, ob die Evozierung eines Angstzustandes Aspekte der Reizgeneralisierung beeinflußt. Methode: Je 16 Schlangen- oder Spinnenphobikerinnen werden mit zwei unterschiedlichen Stimulus-Serien (Kobras bzw. Kreuzspinnen) konfrontiert, aufbauend auf einem Peak-Shift-Paradigma. In einer Lernphase erfolgt durch aversive klassische Konditionierung ein Diskriminations-Training zwischen zwei Hinweisreizen einer Stimulus-Serie, anschließend wird die Reizgeneralisierung erfaßt. Ergebnisse: Für phobierelevante Reize zeigt sich eine Verschiebung des Maximums der Generalisations-Gradienten (Peak-Shift). Schlussfolgerung: Dieser angstinduzierte Peak-Shift kann im Sinne einer eingeschränkten Fähigkeit interpretiert werden, bereits gelernte Sicherheitsinformationen (Ausbleiben aversiver Konsequenzen) über phobische Reize auf weitere Konfrontationen mit ähnlichen Reizen zu generalisieren. Derartige Prozesse könnten zur Pathogenese spezifischer Phobien beitragen, indem sie die Bildung eines abweichenden emotionalen Gedächtnisses begünstigen.

Abstract
There is now considerable evidence that phobic responding is associated with a bias towards expecting aversive or traumatic outcomes following encounters with the phobic stimulus (e.g. Behavioural Brain Sci. 18 (1995) 289-325; Phobias: A Handbook of Theory, Research and Treatment. Wiley, Chichester, 1997). In terms of conditioning contingencies, this can be described as a bias towards expecting an aversive unconditioned stimulus (UCS) following a phobic conditioned stimulus (CS). The disease-avoidance model of animal fears (Anxiety Res. 4 (1992a) 314; Matchett and Davey, 1991) suggests that common animal fears may be mediated by at least two kinds of selective associations: (1) a bias towards expecting physically harmful consequences associated with predatory animals, and (2) a bias towards expecting disgust or disease-relevant consequences associated with animals that are fear-relevant (FR) but normally physically harmless. The present study investigated this model of selective associations by comparing the UCS expectations elicited by high-predation FR, low-predation FR and safe (fear-irrelevant) animals. The results indicate that high-predation animals are selectively associated with a pain relevant UCS, whilst low-predation animals are selectively associated with a disgust-relevant UCS. Safe animals were not strongly associated with either class of UCS. These findings provide evidence for a possible associative mechanism by which changes in nonspecific levels of disgust sensitivity may directly affect levels of fear to low-predation FR animals.

Abstract
Probabilistic learning was studied in spider-fearful and in panic-prone individuals. Participants learned to predict the occurrence of aversive outcomes on the basis of relevant and irrelevant stimuli. The salience of irrelevant stimuli was manipulated by the use of threat-related objects, i.e. pictures of spiders and pictures of emergency situations. In spider-fearful individuals, the presence of irrelevant pictures of spiders interfered with the adequate acquisition of the association between neutral relevant stimuli and aversive outcomes. Salient, i.e. threat-related, irrelevant stimuli exerted competitive effects on the accruing of associative strengths between neutral stimuli and aversive outcomes in spider-fearful, but not in panic-prone, individuals.

Abstract
The present study reports results from a study of the self-reported fears of identical twins and their spouses and offspring. Factor analysis with oblique rotation of questionnaire responses yielded four correlated fear dimensions: situational fears, illness-injury fears, social fears, and fear of small animals. Models allowing for genetic and cultural transmission, together with specially correlated environments for twins, were fitted, both for separate fears and across fears. Simple models with only genetic and uncorrelated environments were sufficient to account for each the fear dimensions considered separately. The cross-dimensional analyses revealed a genetic and an environmental factor common to the four fear dimensions, together with fear-specific genetic and environmental factors. The impact of the common genetic and common environmental factor varied across dimensions. No evidence of cultural transmission or specially correlated twin environments of the cross-dimensional environments was detected. It is concluded that both common and fear-specific genes and (individual-specific) common and fear-specific environments are necessary to account for the data. The results are discussed in terms of the prepared learning hypothesis and the expectancy bias hypothesis.

Abstract
We describe evidence for an evolved module for fear elicitation and fear learning with four primary characteristics. First, it is preferentially activated by stimuli related to survival threats in evolutionary history. Thus, fear-relevant stimuli lead to superior conditioning of aversive associations compared with fear-irrelevant stimuli. Second, the module is automatically activated by fear-relevant stimuli, meaning that fear activation occurs before conscious cognitive analysis of the stimulus can occur. Third, the fear module is relatively impenetrable to conscious cognitive control, and fear conditioning with fear-relevant stimuli can occur even with subliminal conditioned stimuli. Fourth, the amygdala seems to be the central brain area dedicated to the fear module. Finally, we propose that there are two levels of fear conditioning, with an emotional level that is relatively independent of the cognitive contingency level, each mediated by different brain areas.

Abstract
This article examines evolutionary mechanisms in human fear and anxiety, with a particular focus on specific phobias and social phobia. The contribution of evolutionary factors to the development of specific phobias has led to refinements and modifications of earlier conditioning theories. Evolutionary mechanisms further affect cognitive factors of fear and anxiety, such as self-related processes and social comparisons, as in the case of social phobia. Although not without controversy, an evolutionary theory of human fear and anxiety adds a unique perspective that could potentially lead to improved psychopathology models, nosological systems, and treatment strategies for anxiety disorders.

Abstract
A covariation bias (CB) reflects the overestimation of an objectively random covariation between fear-relevant picture stimuli (e.g., spiders) and aversive consequences (e.g., electric shocks). The affect-modulated startle (AMS) paradigm is similar to it because aversive reflex probes are delivered in the context of unpleasant, neutral or pleasant picture stimuli. The present study explored if a covariation bias is present in the affect-modulated startle paradigm. There was a covariation bias for unpleasant and pleasant compared to neutral pictures probably due to differences in arousal. Startle reflexes were modulated by picture valence. No correlation between a covariation bias index and the startle response modulation was found. It is concluded that both phenomena are mediated by different underlying mechanisms.

Abstract
The growth of evolutionary psychology as a theoretical framework for the study of human behavior has been spectacular. However, evolutionary psychology has been largely ignored by clinical psychology. This article is an attempt to encourage greater dialogue between the two. First, some of the major principles of evolutionary psychology are outlined, followed by consideration of some of the criticisms that have been made of this approach. Second, an attempt is made to trace the influence of evolutionary theory on the history and development of clinical psychology. Third, the authors describe how an evolutionary perspective has enhanced the understanding and study of autism and depression. Finally, some implications of an evolutionary perspective for etiological theory, assessment, treatment, and ethics are discussed.

Abstract
Symptom episodes often show a spatio-temporal structure, that is, they occur in a specific context for a certain duration. Repeated experiences may therefore be construed as associative learning trials, in which context elements are turned into predictive cues, triggering anticipatory processes conducive to subjective health complaints. A series of experiments, using inhalations of air enriched with CO2 and external (odors) or internal (mental images) stimuli as cues, is discussed to show that subjective health complaints may occur upon presenting the cue alone. Learned symptoms may be unrelated to bodily responses and easily generalize to new related cues. Better learning occurs to cues with a negative affective valence and in participants scoring high for negative affectivity. Our findings are relevant to the understanding of medically unexplained ("functional") syndromes and the poor relationship between objective and subjective health indicators in general.
