Coping with test anxiety using imagery rescripting: A two-session randomized controlled trial.

BACKGROUND: Up to 55 % of students experience test anxiety (TA), which is characterized by intense physiological and psychological symptoms before or during exams, such as anxiety, fear of failure, sweating, or increased heart rate. Furthermore, TA increases graduation times and can result in discontinuance of the graduate program all together. Previous research demonstrated the beneficial effects of combining cognitive behavioral therapy with imagery rescripting, however, treatment programs are comparably long. Hence, they do not account for the students´ time-sensitive schedules. Therefore, the present study investigates a two-session short-intervention using imagery rescripting to treat TA. METHODS: 44 students and pupils were randomly assigned to either the two-session imagery rescripting intervention (22 participants) or the waitlist-control condition (22 participants). One week before the intervention clinical interviews were conducted and self-report questionnaires on TA, self-efficacy, symptoms of depression, and intrusive prospective images were completed (T1). The same questionnaires were completed one week (T2) and six months after the intervention (T3). RESULTS: Test anxiety significantly decreased from T1 to T2, as well as from T1 to T3 within the intervention group. Furthermore, there were medium to large within and between group effects for situational test anxiety, self-efficacy, symptoms of depression, as well as prospective intrusive images, showing significant improvements for the intervention group at six months follow-up. LIMITATIONS: The study is limited to the comparably small sample size, as well as the sole usage of self-report measurements. CONCLUSIONS: The presented short-intervention provides a feasible treatment technique, which can be easily applied within school and university counseling centers.

Health anxiety amplifies fearful responses to illness-related imagery.

Severe health anxiety (HA) is characterized by excessive worry and anxiety about one's health, often accompanied by distressing intrusive imagery of signs of a serious illness or potentially receiving bad news about having a life-threatening disease. However, the emotional responses to these illness-related mental images in relation to HA have not been fully elucidated. Emotional responses to mental imagery of 142 participants were assessed in a well-controlled script-driven imagery task, systematically comparing emotional responses to illness-related imagery with neutral and standard fear imagery. The results revealed that participants reported higher anxiety, aversion, emotional arousal, and a stronger avoidance tendency during imagery of fear and illness-related scenes compared to neutral scenes. Importantly, the emotional modulation varied by the level of HA, indicating that individuals with higher HA experienced stronger emotional responses to illness-related imagery. This association between HA and fearful imagery could not be better accounted for by other psychological factors such as trait anxiety, anxiety sensitivity, somatic symptom severity, or symptoms of depression and anxiety. Fearful responding to standard threat material was not associated with HA. The present findings highlight the importance of considering fear responding to mental imagery in understanding and addressing HA.

Application of the Model of Spots for Inverse Problems.

This article proposes the application of a new mathematical model of spots for solving inverse problems using a learning method, which is similar to using deep learning. In general, the spots represent vague figures in abstract "information spaces" or crisp figures with a lack of information about their shapes. However, crisp figures are regarded as a special and limiting case of spots. A basic mathematical apparatus, based on L4 numbers, has been developed for the representation and processing of qualitative information of elementary spatial relations between spots. Moreover, we defined L4 vectors, L4 matrices, and mathematical operations on them. The developed apparatus can be used in Artificial Intelligence, in particular, for knowledge representation and for modeling qualitative reasoning and learning. Another application area is the solution of inverse problems by learning. For example, this can be applied to image reconstruction using ultrasound, X-ray, magnetic resonance, or radar scan data. The introduced apparatus was verified by solving problems of reconstruction of images, utilizing only qualitative data of its elementary relations with some scanning figures. This article also demonstrates the application of a spot-based inverse Radon algorithm for binary image reconstruction. In both cases, the spot-based algorithms have demonstrated an effective denoising property.

Communication as the Origin of Consciousness.

Since the middle of the 20th century, more and more data have appeared on the limited role of consciousness in determining human behavior. In this opinion paper, we hypothesize that the basis of consciousness is precisely the communicative function, and discuss relations of consciousness to other cognitive processes such sensory detection, decision-making and emotions. Within the framework of the hypothesis, consciousness is considered as a highly specialized function of the brain, which ensures encoding of personal information as communication messages. On a subjective level, mental representation just means the state of information to be shared in a human group. Accordingly, consciousness affects only those components of human behavior that are associated with the transmission of messages. Sensory detection, decision-making, emotions and other processes are only projected into consciousness during the encoding of information of them. The communication hypothesis assumes that consciousness is an adaptation that increases the efficiency of a collective way of life, and the emergence of consciousness is inextricably linked with the development of language in human culture. In the future, our view of consciousness provides an opportunity for an objective analysis of subjective phenomena by means of a directed study of the formation of messages both at the level of brain processes and at the level of interactions between individuals.

Adoption of measures to mitigate the impact of COVID-19: In search of a Hofstedian explanation for patterns among individual countries and country clusters.

We consider multiple safety measures in relation to the COVID-19 virus and look at their adoption levels for a variety of 15 individual countries, based on data from Yougov.co.uk. Subsequently, we establish correlation coefficients between measure-specific uptake levels and Hofstede dimension scores for all countries considered. We notably find that Power Distance Index (PDI) and Individualism (IDV) have a considerable explanatory power. In addition, we carried out a Principal Components Analysis (PCA) and a cluster analysis to see whether the behavioural patterns across countries can be grouped, and which Hofstede dimensions correlate strongest with the two main components that follow from the PCA. The PCA provides further confirmation of PDI and IDV being the most important explanatory factors for the uptake of measures across countries. The cluster analysis, in turn, reveals four broad groups, which only partly coincide with the way that the mental image clustering scheme by Wursten (2019) allots countries into its respective clusters. Hence, this provides a basis to suggest that data-driven exercises like the ones from our paper can serve to adjust Wursten's intuitive scheme.

Mental imagery in adolescent PTSD patients after child abuse: a comparison with matched healthy controls.

BACKGROUND: Intrusive mental imagery (MI) plays a crucial role in the maintenance of posttraumatic stress disorder (PTSD) in adults. Evidence on the characteristics of MI in adolescents suffering from PTSD is sparse. The aim of this study was to thoroughly assess MI in an adolescent sample suffering from PTSD after the experience of childhood sexual abuse and/or childhood physical abuse (CA). METHODS: Thirty-two adolescents with a primary diagnosis of PTSD after CA and 32 adolescents without any mental disorder and without a history of CA, matched for age and gender, completed questionnaires assessing the characteristics of negative and positive MI, as well as images of injury and death that lead to positive emotions (ID-images). RESULTS: The PTSD group reported significantly more frequent, more vivid, more distressing and more strongly autobiographically linked negative MI compared to the control group. Although positive MI was highly present in both groups (PTSD: 65.6%; controls: 71.9%), no significant differences emerged between the two groups regarding the distinct characteristics of positive MI. The frequency of the ID-images did not significantly differ between the two groups (PTSD: 21.9%; controls: 9.4%), although the ID-images were more vivid in the PTSD group. DISCUSSION: Negative MI appears to be crucial in adolescent PTSD, whilst positive MI are unexpectedly common in both the PTSD and the control group. The role of positive MI as well as that of ID-images remain unclear. Specific interventions for changing negative MI that are tailored to the developmental challenges in adolescents with PTSD should be developed. TRIAL REGISTRATION: Some of the PTSD patients in this study were also part of a randomized controlled trial on Developmentally adapted Cognitive Processing Therapy (D-CPT). This trial was registered at the German Clinical Trial Registry (GCTR), DRKS00004787 , 18 March 2013.

Health anxiety is associated with fearful imagery of contracting COVID-19: An experimental study.

BACKGROUND: Aversive mental images of contracting or having a severe disease are assumed to contribute to the development and maintenance of health anxiety (HA) via the elicitation of fear, arousal and defensive mobilization. The current COVID-19 pandemic is known to trigger fears of contracting COVID-19. METHODS: In this study, we used an experimental approach to investigate whether COVID-19-related mental images lead to a fearful response and whether this is associated with levels of HA. 139 participants vividly imagined neutral, standard fear and COVID-19 related narrative scenes. RESULTS: Standard fear and COVID-19 scripts prompted higher anxiety, arousal, displeasure and avoidance tendencies as compared to neutral scripts. HA was associated with higher anxiety, arousal, displeasure, imagery vividness and stronger avoidance tendencies during imagery of COVID-19 scenes. No associations were found for anxiety sensitivity, trait anxiety as well as depressive and anxiety symptoms. Moreover, there was no association of HA with emotional responses during imagery of standard fear scenes. LIMITATIONS: Fear responses were assessed via verbal reports. Future studies should also assess behavioral and physiological correlates of fear. CONCLUSIONS: The present results indicate that individuals with high levels of HA are prone to fearful mental imagery of contracting COVID-19 which might be crucial factor contributing to the exacerbation and chronicity of excessive HA in times of a pandemic.

The Association Between Test Anxiety, Self-Efficacy, and Mental Images Among University Students: Results From an Online Survey.

Background and Objectives: A substantial portion of students report test anxiety, and those reporting low levels of self-efficacy seem to be especially affected. Previous research has indicated the relevance of mental images in the maintenance of anxiety disorders, however, no data are available with respect to test anxiety. In order to close this gap, the present study investigates the association between test anxiety, self-efficacy and mental images. Method: One hundred sixty-three university students completed an online survey. Test anxiety (PAF), general self-efficacy (WIRKALL-r), study-related self-efficacy (WIRK_STUD), intrusiveness of mental images (IFES), spontaneous use of imagery (SUIS) and vividness of imagery (VVIQ) were examined. Results: Test-related mental images were frequently reported among the surveyed students. Test anxiety showed a positive correlation with IFES and a negative correlation with self-efficacy. Mediation analyses showed that about one fifth of the influence of self-efficacy on test anxiety is mediated by IFES. Discussion: The present study gives first indication about an association between test anxiety, self-efficacy and mental images, even though the results are limited with respect to generalizability. Further investigations with respect to the impact of test-related mental images on the self-efficacy/test-anxiety linkage are needed.

Mental imagery rotation and graph comprehension of IS-LM macroeconomic models.

The aim of this study was to determine if the ability to rotate mental imagery influenced the comprehension of graphs in economics. A sample of 140 Business Administration undergraduates familiar with economic analysis using graphs were administered the Measure of the Ability to Rotate Mental Images (MARMI). Moreover, participants completed an ad hoc graph comprehension test consisting of six exercises of increasing difficulty with graphs developing the IS-LM model described in conventional macroeconomic textbooks. Both the ability to rotate mental imagery and graph complexity (the number of quadrants in each graph) were found to significantly influence the number of correct graph comprehension responses.

Neural representations underlying mental imagery as unveiled by representation similarity analysis.

It is commonly acknowledged that visual imagery and perception rely on the same content-dependent brain areas in the high-level visual cortex (HVC). However, the way in which our brain processes and organizes previous acquired knowledge to allow the generation of mental images is still a matter of debate. Here, we performed a representation similarity analysis of three previous fMRI experiments conducted in our laboratory to characterize the neural representation underlying imagery and perception of objects, buildings and faces and to disclose possible dissimilarities in the neural structure of such representations. To this aim, we built representational dissimilarity matrices (RDMs) by computing multivariate distances between the activity patterns associated with each pair of stimuli in the content-dependent areas of the HVC and HC. We found that spatial information is widely coded in the HVC during perception (i.e. RSC, PPA and OPA) and imagery (OPA and PPA). Also, visual information seems to be coded in both preferred and non-preferred regions of the HVC, supporting a distributed view of encoding. Overall, the present results shed light upon the spatial coding of imagined and perceived exemplars in the HVC.

Profiles of Perfectionistic Ruminations in Undergraduates: Impact on the Spontaneous Use of Mental Images.

Perfectionistic Automatic Thoughts (PAT) negatively affects people who present it. Hence the importance of their study to determine possible ways of reduction. The current study tried to identify PAT profiles and specify the statistically significant differences in the Spontaneous Use of Mental Imaging in 647 undergraduates. For this the Perfectionism Cognitions Inventory and the Spontaneous Use of Imagery Scale were used. The cluster analyses showed three groups of PATs; low (LPAT), moderate (MPAT) and high (HPAT). An analysis of variance revealed moderate size differences in the visual-spatial capacity as well as in the total of the Spontaneous Use of Mental Images for MPAT and LPAT. Implications for the training of future teachers related to the use of mental imagery that can reduce maladaptive PAT are discussed.

Imagery Rescripting: Exploratory Evaluation of a Short Intervention to Reduce Test Anxiety in University Students.

BACKGROUND: Test anxiety is common in university students. Demanding schedules may contribute to the relatively low utilization of professional counseling, when compared to other anxiety disorders. A possible solution could be a psychotherapeutic short-term intervention. The present exploratory study implemented a short-term psychotherapeutic treatment, consisting of two imagery rescripting (IR) sessions. The efficacy of IR techniques has already been demonstrated in the treatment of various anxiety disorders including test anxiety. METHODS: Nine students suffering from test anxiety (m = 3, f = 6) underwent two weekly applied sessions of IR. Outcome variables were examined one week prior to (t1), immediately after (t2) and three months after (t3) the intervention, using self-evaluation questionnaires on test anxiety (PAF), depressive symptoms (BDI II), life satisfaction (FLZ), general self-efficacy and study-specific self-efficacy (WIRKALL; WIRK_STUD), intrusiveness of mental images (IFES), and change and acceptance (VEV; ZUF; BFTB). RESULTS: There were no dropouts. According to results from ZUF and BFTB, the participants where highly satisfied with the intervention. PAF scores decreased significantly over time (t1 to t3), whereas WIRKALL scores (t1 to t3) and WIRK_STUD scores (t1 to t3 and t2 to t3) increased significantly. IFES scores decreased immediately after the intervention (t1 compared to t2) and further after the follow-up (t1 to t3). No changes in BDI-II scores were observed. DISCUSSION: The findings indicate a high acceptance and efficacy of the two-session IR-intervention. Limits are the lack of a control group, and the small sample size. Further evaluation in future controlled studies is needed.

Mental images, entrapment and affect in young adults meeting criteria of nonsuicidal self-injury disorder (NSSID) - a daily diary study.

BACKGROUND: Incidents of nonsuicidal self-injury (NSSI) are often accompanied by mental images which could be perceived as distressing and/or soothing; yet existing data is derived from participants with a history of NSSI using retrospective methods. This study investigated mental images related to NSSI ("NSSI-images"), and their relationship to the proposed Nonsuicidal Self-Injury Disorder (NSSID). METHODS: An e-mail was sent to all female students of the local University providing the link to an online screening and 201 students with a history of repetitive NSSI responded. Nineteen eligible participants meeting criteria of NSSID (mean age = 25; 32% with migrant background) further completed a baseline interview and a ten-day-diary protocol. RESULTS: Among the sample of N = 201, 83.6% reported NSSI-images. In the subsample of n = 19 diagnosed with NSSID, the frequencies of NSSI and NSSI-images were correlated; about 80% of the most significant NSSI-images were either of NSSI or of an instrument associated with NSSI (i.e., a razorblade). In the diary, 53% of the sample self-injured. NSSI-images were reported on 94% of NSSI-days, and on days with NSSI and NSSI-images, the images almost always occurred first; the images were overall perceived as twice more distressing than comforting. Images on NSSI-days were characterized by more comfort, intrusiveness and compellingness yet less vividness, and increased subsequent positive and negative affect compared to non-NSSI days. NSSI-days were further marked by increased entrapment beliefs and increased negative yet decreased positive affect at night. These results were non-significant. LIMITATIONS: Due to non-significant results among a small sample size and a low rate of NSSI among the NSSID-group, results remain preliminary. CONCLUSIONS: The study provides information on feasibility and methodological challenges such as intervention effects of the diary. NSSI-images may be common among individuals who engage in NSSI; they may capture ambivalent (positive and negative) appraisals of NSSI and thus play a role in NSSI and possibly a disorder such as NSSID. The preoccupation with NSSI (Criterion C of NSSID in DSM-5) may as well be imagery-based. REGISTRATION: The study was retrospectively registered with the DRKS under the number DRKS00011854.

The dynamic contribution of the high-level visual cortex to imagery and perception.

Mental imagery and visual perception rely on the same content-dependent brain areas in the high-level visual cortex (HVC). However, little is known about dynamic mechanisms in these areas during imagery and perception. Here we disentangled local and inter-regional dynamic mechanisms underlying imagery and perception in the HVC and the hippocampus (HC), a key region for memory retrieval during imagery. Nineteen healthy participants watched or imagined a familiar scene or face during fMRI acquisition. The neural code for familiar landmarks and faces was distributed across the HVC and the HC, although with a different representational structure, and generalized across imagery and perception. However, different regional adaptation effects and inter-regional functional couplings were detected for faces and landmarks during imagery and perception. The left PPA showed opposite adaptation effects, with activity suppression following repeated observation of landmarks, but enhancement following repeated imagery of landmarks. Also, functional coupling between content-dependent brain areas of the HVC and HC changed as a function of task and content. These findings provide important information about the dynamic networks underlying imagery and perception in the HVC and shed some light upon the thin line between imagery and perception which has characterized the neuropsychological debates on mental imagery.

Linguistic Conceptualizations of Disease Among the Luo of Kenya.

The region inhabited by the Luo ethnic group in Kenya is disease endemic. However, disease awareness initiatives register low acceptance due to the sociocultural images of disease and illness conceptualized in the local Dholuo language in ways that may contradict modern biomedical knowledge and practice. This article evaluates the sociocultural basis of encoding descriptions of disease in the Luo indigenous knowledge system and their implications for modern medical practice. The methodology entailed use of qualitative interviews of purposively sampled Dholuo-speaking patient escorts in a provincial referral hospital. Nonparticipant observation was also conducted at funerals to monitor contextualized usage of the discourse of disease, illness, and death. The data were analyzed using qualitative content analysis and categorized into emergent themes and categories. The results revealed that Dholuo is replete with expressions that emphasize the vulnerability and discrimination of the sick. Such attitudes cause rejection of interventions and negatively influence health-seeking behavior. The expressions were relevant and acceptable to cultural insiders; hence, they could determine their understanding of health conditions thereby influencing how they make medical decisions. It emerges that the unique Luo worldview controls their perceptions on the causes of disease and prescribes community-driven remedies which may depart from the expectations of the biomedical model.

Treating women with perinatal mood and anxiety disorders (PMADs) with a hybrid cognitive behavioural and art therapy treatment (CB-ART).

This paper presents an overview of a combined, evaluated protocol, cognitive behavioural and art therapy treatment (CB-ART), for the treatment of women with perinatal mood and anxiety disorders (PMADs). The protocol integrates cognitive behavioural interventions and art therapy. CB-ART focuses on changing distressing image, symptom or memory (ISM) that interferes with functioning. The method directs clients to identify compositional elements that characterize their stressful ISM and to alter the element in their imagination, in bodily sensations and on the page. Examples are provided to illustrate the therapeutic process.

Imagining Change: An Integrative Approach toward Explaining the Motivational Role of Mental Imagery in Pro-environmental Behavior.

Climate change and other long-term environmental issues are often perceived as abstract and difficult to imagine. The images a person associates with environmental change, i.e., a person's environmental mental images, can be influenced by the visual information they come across in the public domain. This paper reviews the literature on this topic across social, environmental, and cognitive psychology, and the wider social sciences; thereby responding to a call for more critical investigations into people's responses to visual information. By integrating the literature we come to a better understanding of the lack in vivid and concrete environmental mental imagery reported by the public, the link between environmental mental images and goals, and how affectively charged external images could help in making mental imagery less abstract. Preliminary research reports on the development of a new measure of environmental mental imagery and three tests of the relationship between environmental mental imagery, pro-environmental goals and behavior. Furthermore, the paper provides a program of research, drawing upon approaches from different disciplines, to set out the next steps needed to examine how and why we should encourage the public to imagine environmental change.

Distressing visual mental images in depressed patients and healthy controls - Are they one and the same?

Negative mental images are common in a range of mental disorders. So far, only inconclusive evidence has been obtained for depression specificity. We assessed the disparities and similarities of a variety of imagery characteristics in 17 patients suffering from depressive disorders and 17 healthy matched controls who all reported negative mental images. The number of intrusive images, their frequency, and the associated distress were significantly greater for the depressed individuals. Compared with non-depressed controls, negative images during depression were more frequently triggered by internal factors and led to depression-related emotions. Approximately 30% of the images in the depressed group did not consist of actual memories of real-life events. No significant differences in vividness or perceived controllability were observed, but the depressed patients experienced significantly more bodily symptoms during the intrusions than the healthy controls. The results indicate that the central characteristics of the negative mental images of depressed and non-depressed individuals are distinguishable, despite some similarities, and may contribute to depressive symptoms.

Age effect in generating mental images of buildings but not common objects.

Imagining a familiar environment is different from imagining an environmental map and clinical evidence demonstrated the existence of double dissociations in brain-damaged patients due to the contents of mental images. Here, we assessed a large sample of young and old participants by considering their ability to generate different kinds of mental images, namely, buildings or common objects. As buildings are environmental stimuli that have an important role in human navigation, we expected that elderly participants would have greater difficulty in generating images of buildings than common objects. We found that young and older participants differed in generating both buildings and common objects. For young participants there were no differences between buildings and common objects, but older participants found easier to generate common objects than buildings. Buildings are a special type of visual stimuli because in urban environments they are commonly used as landmarks for navigational purposes. Considering that topographical orientation is one of the abilities mostly affected in normal and pathological aging, the present data throw some light on the impaired processes underlying human navigation.
