Effects of verbal information on fear-related reasoning biases in children

Disconfirmation of confirmation bias: the influence of counter-attitudinal information

The current experiment investigated whether counter-attitudinal information can alter a pre-existing attitude and the accompanying confirmation bias. Sixty-three non-clinical children (9–12 years) were shown pictures of a positive animal (quokka) or a dangerous-looking animal (aye aye). For both animals attitudes and information seeking patterns were obtained. Next, they received counter-attitudinal information of each animal; attitudes and seeking patterns were reassessed. We found that the aye aye was perceived as more dangerous and less kind compared to the quokka. A negative confirmation bias was observed for the aye aye, more negative than positive or neutral information was requested. For the quokka this pattern was absent, more positive and negative than neutral information was selected. The counter-attitudinal information decreased the scariness of the aye aye, but did marginally alter that of the quokka. Additionally, for the aye aye counter-attitudinal information increased search for positive and neutral information and decreased search for negative information. For the quokka the counter-attitudinal information only increased search for neutral information. The animals no longer differed from each other and no clear confirmation bias patterns were present. These results indicate that it is possible to change pre-existing values and their accompanying information search patterns.

The social learning of threat and safety in the family: Parent-to-child transmission of social fears via verbal information

Parental verbal threat (vs. safety) information regarding the social world may impact a child's fear responses, evident in subjective, behavioral, cognitive, and physiological indices of fear. In this study, primary caregivers provided standardized verbal threat or safety information to their child (N = 68, M = 5.27 years; 34 girls) regarding two strangers in the lab. Following this manipulation, children reported fear beliefs for each stranger. Physiological and behavioral reactions were recorded as children engaged with the two strangers (who were blind to their characterization) in a social interaction task. Child attention to the strangers was measured in a visual search task. Parents also reported their own, and their child's, social anxiety symptoms. Children reported more fear for the stranger paired with threat information, but no significant differences were found in observed child fear, attention, or heart rate. Higher social anxiety symptoms on the side of the parents and the children exacerbated the effect of parental verbal threat on observed fear. Our findings reveal a causal influence of parental verbal threat information only for child-reported fear and highlight the need to further refine the conditions under which acquired fear beliefs persist and generalize to behavior/physiology or get overruled by nonaversive real-life encounters.

Preventing and reducing fear using positive modelling: A systematic review of experimental research with children

Fear of specific stimuli is thought to develop through associative learning mechanisms and research indicates that a form of observational (vicarious) learning known as positive modelling can counter these effects. This systematic review examined and synthesised the experimental positive modelling literature to establish its efficacy for reducing fear. Psych Info, Medline and the Psychology and Behavioural Science Collection databases were systematically searched until August 2021. Of the 1,677 papers identified, 18 experiments across 14 articles met the inclusion criteria. In the majority of these, positive modelling was found to lower fear levels in one or more of three procedures: fear prevention, fear reduction and fear reversal. Procedures inform prevention and treatment initiatives for specific phobias in several ways. The overall efficacy of positive modelling techniques and the ease in which they can be implemented highlight the importance of further research to evaluate their inclusion in prevention and treatment interventions. More research is required to establish the longevity and transferability of positive modelling.

Filthy fruit! Confirmation bias and novel food

Fruit and vegetable consumption is worldwide too low, resulting in poor diet quality and health-related problems. A cognitive factor that might contribute to this low consumption is confirmation bias. Confirmation bias has been established in anxiety research and comprises the tendency to search for reinforcing negative information, while ignoring counter attitudinal information. If applicable to food, asking for negative food information reinforces the negative attitude and decreases the willingness to try (novel) food. The aim of the current study was twofold. First, to examine if confirmation bias translates to food stimuli. Second, to investigate if this bias is exaggerated in persons with higher levels of food neophobia. To this end, 117 participants (age M = 21.45, SD = 4.48) carried out an online study. They filled in the food neophobia scale (FNS) and performed a search for additional information scale (SAIS) task. Four novel fruits were used, two looking tasteful (pomelo and rose apple) and two looking non-tasteful (black sapote and noni fruit). Participants rated their willingness to eat these fruits and subsequently could indicate how eager they were to receive positive or negative information regarding that fruit. The results indicated that the participants were more willing to try the tasteful looking fruits than the non-tasteful. Additionally, higher levels of food neophobia coincided with less willingness to eat all fruits. Confirmation bias was observed, more negative information was requested for the non-tasteful than for the tasteful fruits. This bias was not related to levels of food neophobia. These results are important as confirmation bias might make people even more negative towards novel foods and could contribute to even less fruit and vegetable consumption, especially when they look less appetizing.

Brain and Behavior Correlates of Risk Taking in Pediatric Anxiety Disorders

Avoidant behavior is a defining feature of pediatric anxiety disorders. Although prior research has examined it from the perspective of early information processing events, there has been relatively less consideration of the processes by which anxious youth make avoidant decisions and how these choices are reinforced over time. Studies of risk taking are valuable in this regard because they consider how individuals identify the pros and cons of their choices, how they weigh potential gains and losses and estimate their respective probabilities, and how they tolerate the uncertainty intrinsic to any decision. In this review, we place risk taking within existing models of information processing in pediatric anxiety disorders and highlight the particular value of this construct for informing models of developmental psychopathology and individual differences in outcome over time. We review existing behavioral and neurobiological studies of risk taking in anxious youth and conclude by identifying directions for future research.

A Longitudinal Study on the Relations Among Fear-Enhancing Parenting, Cognitive Biases, and Anxiety Symptoms in Non-clinical Children

This longitudinal study explored the relations between fear-enhancing parenting behaviors (modeling and threat information transmission) and children's cognitive biases and anxiety symptoms on three subsequent time points over a one-year period. Participants were 216 children aged 7-12 years (114 boys and 102 girls), and their mothers (n = 199) and/or fathers (n = 117). On each time point, children and parents completed the Parental Enhancement of Anxious Cognitions scale, which measures parental modeling and threat information transmission. Furthermore, children filled in a measure of anxiety disorder symptoms. In addition, confirmation bias and interpretation bias were measured by means of a number of computerized tasks. The results yielded support for a circular model in which cognitive biases enhanced anxiety symptoms, which in turn promoted cognitive biases on each of the three time points. However, no evidence was found for longitudinal effects of cognitive biases on anxiety or vice versa. In contrast to what we expected, cognitive biases and anxiety appeared to promote parental modeling and threat information rather than the other way around. These findings extend research on the relations between parenting behaviors, cognitive biases, and childhood anxiety symptoms, and suggest valuable leads for assessment and intervention.

The influence of stimulus valence on confirmation bias in children

BACKGROUND AND OBJECTIVES

The aim of the present study was to replicate our previous study and to further examine the relation between fear and positive and negative confirmation bias in children.

METHODS

Fifty-three non-clinical children (9-13 years) were shown pictures of a kindly-perceived (quokka) and a dangerous-looking (aye aye) animal. For each animal, levels of fear and information seeking patterns were obtained.

RESULTS

The results indicated that the aye aye was rated as more threatening and less kind than the quokka. For the aye aye more negative than neutral or positive information was selected; no differences were observed for the quokka. Regardless of type of animal, higher fear levels coincided with more search for negative information. Positive confirmation bias in the quokka was indirectly observed as low fear levels were associated with an increased search for positive information. Finally, for the quokka searching negative information coincided with an increase in the scariness of the quokka; this pattern was absent for the aye aye.

LIMITATIONS

Though the results are informative, no clinically anxious children were tested, a positive beliefs questionnaire was lacking and children were forced to select one of the presented answer alternatives.

CONCLUSIONS

The present study indicates that the mere perception of danger can trigger confirmation bias; a positive view can, in case of low fear levels, result in increased search for positive information. Additionally, a relation was observed between increased negative attitude and search for negative information. The results, implications and suggestions for future research are discussed.

Cognitive Bias as a Mediator in the Relation Between Fear-Enhancing Parental Behaviors and Anxiety Symptoms in Children: A Cross-Sectional Study

The present cross-sectional study explored the relations between fear-enhancing parenting behaviors (modeling and threat information transmission) and children's cognitive biases and anxiety symptoms. Participants were 258 children aged 7-12 years (132 boys and 126 girls), and their mothers (n = 199) and/or fathers (n = 117). Children and parents completed the Parental Enhancement of Anxious Cognitions questionnaire, which measures parental modeling and threat information transmission, while children also filled in a scale for assessing anxiety symptoms. In addition, children conducted a number of computerized tasks for measuring confirmation and interpretation bias. The data indicated that both biases mediated the relationship between threat information transmission (of both parents) and children's anxiety symptoms. Only interpretation bias significantly mediated the relationship between modeling (of mothers) and anxiety symptoms. These findings give partial support for the hypothesis that cognitive biases play a mediating role in the relation between fear-enhancing parental behaviors and children's anxiety symptoms.

How fear-relevant illusory correlations might develop and persist in anxiety disorders: A model of contributing factors

Fear-relevant illusory correlations (ICs) are defined as the overestimation of the relationship between a fear-relevant stimulus and aversive consequences. ICs reflect biased cognitions affecting the learning and unlearning of fear in anxiety disorders, and a deeper understanding might help to improve treatment. A model for the maintenance of ICs is proposed that highlights the importance of amplified aversiveness and salience of fear-relevant outcomes, impaired executive contingency monitoring and an availability heuristic. The model explains why ICs are enhanced in high fearful individuals and allows for some implications that might be applied to augment the effectiveness of cognitive behavior therapy, such as emotion regulation and the direction of attention to non-aversive experiences. Finally, we suggest possible future research directions and an alternative measure of ICs.

Adaptation of a paradigm for examining the development of fear beliefs through the verbal information pathway in preschool-age children

Verbal threat information has been shown to induce fear beliefs in school-age children (i.e. 6-12 years; for a review see Muris & Field, 2010). The current study adapted an existing paradigm (Field & Lawson, 2003) to examine the impact of verbal threat information on self-report and behavioral measures of fear in preschool-age children. Thirty children (aged 3-5) were provided with threat, positive, or no information about three novel Australian marsupials. There was a significant increase in fear belief for the animal associated with threat information compared to the animal associated with positive or no information. Verbal threat information did not impact behavioral avoidance in the complete sample; however, findings from an exploratory subgroup analysis excluding three-year-olds indicated that children demonstrated significant behavioral avoidance for the threat condition compared to the positive condition. These findings provide additional support for Rachman's theory of fear acquisition (1977, 1991) and suggest this paradigm may be used to examine the age at which verbal threat information becomes a relevant mode of fear acquisition for young children.

Do you think I should be scared? The effect of peer discussion on children's fears

This study investigated whether close friends affect each other's fear responses (fear beliefs and avoidance) when they discuss fear-related issues together. Children (N = 242) aged 7-10 years were first presented with ambiguous and threatening information about two novel animals respectively, after which their fear responses towards each animal were assessed (T1). Next, dyads of close friends had a discussion about their feelings regarding the animals, and their fear responses were measured again (T2). Results showed that children influenced each other's cognitions following the discussion; from T1 to T2 their fear responses became more similar and close friends' fear responses at T1 significantly predicted children's fear responses at T2. Gender pair type predicted change in children's fear responses over time. Children in boy-boy pairs showed a significant increase in fear responses following the discussion; their fear level became more in line with that of other gender pairs at T2, while those in girl-girl pairs showed a significant decrease in their fear beliefs, at least when threatening information was given. Differences in anxiety level between close friends did not affect change in fear responses over time. Altogether, the results indicate that children may affect each other's fears.

Caregiver-reports of Internet Exposure and Posttraumatic Stress Among Boston-Area Youth Following the 2013 Marathon Bombing

Although practitioners and researchers have considered children's television-based terrorism exposure, Internet-based exposure has not been sufficiently examined. We examined the scope and correlates of children's Internet-based exposure following the Boston Marathon bombing among Boston-area youth (N=460; 4-19 years), and the potential moderating role of age. Further exploratory analyses examined patterns of caregiver attempts to regulate child Internet exposure. Caregivers reported on child Internet-based and direct exposure to traumatic bombing-related events, and youth posttraumatic stress (PTS). Online youth consumed on average over two daily hours of Internet coverage, and roughly one-third consumed over three daily hours of coverage. Internet exposure was particularly high among children over 12. Greater Internet-based exposure was associated with PTS, and 12-15 year olds were particularly vulnerable. Further exploratory analyses found that although most caregivers reported believing media exposure can cause children further trauma, a considerable proportion of caregivers made no attempt to restrict or regulate their child's Internet-based exposure. These findings help practitioners clarify forms of indirect exposure that can place youth at risk following terrorism. Future work is needed to examine the important roles caregivers play as media regulators and as promoters of child coping and media literacy following terrorism.

Fear-related confirmation bias in children: a comparison between neutral- and dangerous-looking animals

The purpose of this study was to examine confirmation bias in children without explicitly inducing fear. Eighty non-clinical children (7-13 years) were shown pictures of a neutral animal (quokka) and two dangerous-looking animals (aye aye and possum). For each animal, levels of perceived fear, threat and request for additional threatening or non-threatening information were obtained. A behavioral approach test (BAT) was included as behavioral measure of fear. The results indicated that the aye aye and possum were rated as more threatening and fearful than the quokka. For the aye aye and possum higher fear levels coincided with search for more threatening than non-threatening information. This pattern was absent in non-fearful children and for the non-threatening quokka. During the BAT the quokka was more often approached first compared to the aye aye and possum. Our findings suggest that confirmation bias in children can be observed without using verbal fear induction.

Cognitive bias in action: evidence for a reciprocal relation between confirmation bias and fear in children

BACKGROUND AND OBJECTIVES

Some cognitive models propose that information processing biases and fear are reciprocally related. This idea has never been formally tested. Therefore, this study investigated the existence of a vicious circle by which confirmation bias and fear exacerbate each other.

METHODS

One-hundred-and-seventy-one school children (8-13 years) were first provided with threatening, ambiguous, or positive information about an unknown animal. Then they completed a computerized information search task during which they could collect additional (negative, positive, or neutral) information about the novel animal. Because fear levels were repeatedly assessed during the task, it was possible to examine the reciprocal relationship between confirmation bias and fear.

RESULTS

A reciprocal relation of mutual reinforcement was found between confirmation bias and fear over the course of the experiment: increases in fear predicted subsequent increases in the search for negative information, and increases in the search for negative information further enhanced fear on a later point-in-time. In addition, the initial information given about the animals successfully induced diverging fear levels in the children, and determined their first inclination to search for additional information.

LIMITATIONS

As this study employed a community sample of primary school children, future research should test whether these results can be generalized to clinically anxious youth.

CONCLUSIONS

These findings provide first support for the notion that fearful individuals may become trapped in a vicious circle in which fear and a fear-related confirmation bias mutually strengthen each other, thereby maintaining the anxiety pathology.

Evaluating and approaching a strange animal: children's trust in informant testimony

This study examined 3- to 7-year-old children's reliance on informant testimony to learn about a novel animal. Sixty participants were given positive or negative information about an Australian marsupial from an informant described as a maternal figure or a zookeeper. Children were asked which informant was correct and were invited to touch the animal, which was a stuffed toy hidden in a crate. Overall, younger children endorsed the zookeeper's testimony about the animal, but touched the animal more readily when the maternal figure provided positive information. Older children endorsed the informant who provided positive information, but showed some sensitivity to zookeeper expertise. Age differences were obtained in the association between participant characteristics and informant selection and animal approach behavior.

The differential effects of written and spoken presentation for the modification of interpretation and judgmental bias in children

BACKGROUND

Interpretation training programs, in which individuals are trained to interpret ambiguous scenarios in either a negative or benign way, have proven effective in altering anxiety-related cognitive biases in both children and adults.

AIMS

The current study investigated whether the effects of the interpretation training procedure in children are differentiated according to the mode of presentation of the training.

METHOD

Ninety-four primary school children (aged 10-12 years) scoring above the mean on a social anxiety scale were randomly allocated to four groups, in which they were trained using written or spoken presentation of training materials in either the negative or benign direction.

RESULTS

For the negative training, children who heard the training material spoken aloud (spoken presentation) made more negative interpretations of ambiguous social events, compared to children who read the training material (written presentation). However, for the benign training, there was less clear evidence for a differentiation of the effects between the two modes of presentation, although children in the spoken presentation group performed better in a stressful task and showed a trend to rate their mood as more positive after the task than children in the written presentation group.

CONCLUSIONS

These results not only forward our understanding of the mechanism of the genesis of cognitive bias in children, but also highlight the need for further investigation of how to optimize the effectiveness of interpretation training in children.

Comparing imagery and verbal instructions for the experimental modification of interpretation and judgmental bias in children

BACKGROUND AND OBJECTIVES

Using an interpretation training paradigm, previous research has demonstrated that it is possible to modify interpretation biases in socially anxious children and that trained interpretation bias affects important aspects of social anxiety (Vassilopoulos, Banerjee, & Prantzalou, 2009). The current experiment was designed to replicate and extend the results reported by Vassilopoulos et al. (2009).

METHODS

In a benign interpretation training paradigm, descriptions of ambiguous hypothetical events were presented in a form requiring participants to endorse the more benign of two interpretations. Ninety-four primary school children aged between 10 and 12 years were asked to either imagine these hypothetical events or to read the same descriptions while thinking about their verbal meaning.

RESULTS

Participants in the verbal instructions condition showed greater decreases in negative interpretations and negative emotional consequences of ambiguous events from pre-training to post-training than did those in the imagery instructions condition. Additionally, children in the verbal instructions condition reported a significant decrease in trait social anxiety as well as in their self-reported tendency to discount positive information compared with children in the imagery instructions condition.

LIMITATIONS

The results should be considered in the light of the exclusive use of self-report measures and the small effect sizes observed in some analyses.

CONCLUSIONS

These findings suggest that interpretation training in children can be effective with verbal instructions and highlight the need for further investigation of how to optimize the effectiveness of interpretation training in children.

Facing the Beast Apart Together: Fear in Boys and Girls after Processing Information about Novel Animals Individually or in a Duo

In this experimental study, we made an attempt to examine gender-related peer influences on childhood fear. Nine- to 12-year-old boys and girls were provided with ambiguous and positive information about novel animals and then asked to provide a subjective fear rating of the animals under two conditions: fear of one animal was assessed individually by the child on its own, whereas fear of the other animal was measured after a brief discussion on fear-related issues with a same-gender peer. Results indicated that children who completed the FBQ after a discussion with a same-gender peer displayed lower fear beliefs scores than children who completed the questionnaire fully on their own. This fear-suppression effect was mainly evident in boys after hearing ambiguous information about the novel animals. The implications of these findings are briefly discussed.

Reduction of verbally learned fear in children: a comparison between positive information, imagery, and a control condition

This study explored the effects of positive information and imagery as ways of reducing a verbally installed fear in children. Seventy-two primary school children aged 9-13 years were first exposed to negative information to induce fear of a novel animal, and were then randomly assigned to three interventions: positive information, imagery, or a control condition. Outcome of various interventions was assessed by means of a standardized scale of fear beliefs and an index of confirmation bias (defined as the tendency to search for threat information in relation to the feared stimulus). Results indicated that both positive information and imagery were more effective in reducing fear than the control condition. Some evidence was also obtained showing that positive information was more effective than imagery, which suggests that this intervention represents the most optimal treatment approach when dealing with verbally acquired fears in children.

The role of verbal threat information in the development of childhood fear. "Beware the Jabberwock!"

Rachman's (Behaviour Research and Therapy 15:372-387, 1977; Clinical Psychology Review 11:155-173, 1991) three pathways theory proposed that childhood fears not only arise as a consequence of direct learning experiences, but can also be elicited by means of threat information transmission. This review looks at the scientific evidence for this idea, which has accumulated during the past three decades. We review research on the influences of media exposure on children's fears, retrospective parent and child reports on the role of threat information in fear acquisition, and experimental studies that explored the causal effects of threat information on childhood fears. We also discuss possible mechanisms by which threat information exerts its influence and the processes relevant to understand the role of this type of learning experience in the origins of fear. Finally, implications for the prevention and intervention of childhood fears are briefly explored, and potential leads for future research will be highlighted.

"Will a Cuscus bite you, if he shows his teeth?" Inducing a fear-related confirmation bias in children by providing verbal threat information to their mothers

Confirmation bias refers to the inclination to selectively search for information that confirms the view that one holds. Research has shown that fearful individuals mainly seek information that confirms dangerousness of the dreaded stimulus or situation (i.e., verification), whereas they have less an eye for information that invalidates threat (i.e., falsification). It has been demonstrated that fear-related reasoning biases also occur in children, but little is known about where these biases originate from. The present study examined the role of mothers in the development of a fear-related confirmation bias in children. More precisely, it was tested whether mothers install such a reasoning bias in their children via verbal threat information. For this purpose, mothers of 52 children aged 9-12 years were provided with either threatening or positive information about a novel animal and then instructed to describe the animal to their child on the basis of a number of open-ended vignettes. Results indicated that mothers who received threat information about the novel animal displayed a fear-related confirmation bias: that is, they relied less on a falsification strategy than mothers who had heard the positive information. Most importantly, mothers passed the bias on to their children. More precisely, after the vignettes task, children of mothers who had received threat information also sought less information to invalidate the dangerousness of the animal than children of mothers who had received positive information.

Mom told me scary things about this animal: parents installing fear beliefs in their children via the verbal information pathway

This study investigated whether fear beliefs can be installed in children after parents had received negatively tinted information about a novel stimulus. Parents of children aged 8-13 years (N = 88) were presented with negative, positive, or ambiguous information about an unknown animal and then given a number of open-ended vignettes describing confrontations with the animal with the instruction to tell their children what would happen in these situations. Results indicated that children's fear beliefs were influenced by the information that was provided to the parent. That is, parents who had received negative information provided more threatening narratives about the animal and hence installed higher levels of fear beliefs in their children than parents who had received positive information. In the case of ambiguous information, the transmission of fear was dependent on parents' trait anxiety levels. More precisely, high trait anxious parents told more negative stories about the unknown animal, which produced higher fear levels in children.
