Affective super-traits and/or individual patterns: a variable-centered and a person-centered approach of primary emotional aspects of personality.

Theoretical approaches of personality structure are diverse. We examine the primary emotional aspects of personality as the correspondence of two mainstream constructs: the lexically-based Big Five (BIG5) and the biologically-based Affective Neuroscience Theory (ANT) within two approaches. In the variable-centered approach (VCA), our aim is to identify affective super-traits; while in the person-centered approach (PCA) to uncover latent profile patterns. 240 participants (177 women, 63 men) completed the 112-item affective neuroscience personality scales (ANPS), and the 44-item Big Five Inventory (BFI). We identified four super-traits: Negative emotions (FEAR, SADNESS, Emotional instability), Positive emotions and stimulation (SEEK, Extraversion), Affiliation and social bonds (reversed ANGER, CARE, Agreeableness), Self-regulation (PLAY, Conscientiousness. Based on the VCA, we conclude that the four super-traits represent two main affective tendencies (Positive emotions and approaching, Negative emotions and avoidance), interpersonal (Affiliation) and intrapersonal (Self-regulation) dynamics of personality. As a result of Latent Profile Analysis in the PCA, we explored three latent groups with different patterns of primary emotional traits based on their responsiveness (Highly emotional, Balanced, Low emotional). Our findings provide a holistic approach to emotional aspects of personality, and might have further implications for clinical psychology, neuroscience, and cross-cultural studies on emotions.

Psychological well-being, risk factors, and coping strategies with social isolation and new challenges in times of adversity caused by the COVID-19 pandemic.

OBJECTIVE: COVID-19 triggers anxiety and fear due to several reasons, and thus, dealing with it requires prolonged coping mechanisms. When the number of infections soared, to slow the spread, many governments decided to close universities and dormitories and move teaching to online platforms. The majority of the university students decided to move back home to their parents changing their social lives. Here, we aimed to point to risk, as well as protective factors, and understand the influence of these factors on both physical and psychological indicators of well-being. Further, to discover how university students cope with maintaining their social lives during the COVID-19 pandemic. METHOD: We collected online survey data from multiple university sources. Participants (N = 605) completed measures of emotion regulation strategies, knowledge on the disease, contamination fear, perceived social support, worrying and intolerance of uncertainty, quality of sleep, well-being, emotional stability, anxiety, and depression. RESULTS: Our results showed that the most prominent risk and protective factors that were most strongly associated with the indicators of well-being were rumination, catastrophizing, positive refocusing, and social support from family; respectively. CONCLUSION: These results have implications for professionals working with and helping (e.g., as counselors) people during the challenges of an emergency.

Individual differences in the experience of body ownership are related to cortical thickness.

The widely used rubber hand illusion (RHI) paradigm provides insight into how the brain manages conflicting multisensory information regarding bodily self-consciousness. Previous functional neuroimaging studies have revealed that the feeling of body ownership is linked to activity in the premotor cortex, the intraparietal areas, the occipitotemporal cortex, and the insula. The current study investigated whether the individual differences in the sensation of body ownership over a rubber hand, as measured by subjective report and the proprioceptive drift, are associated with structural brain differences in terms of cortical thickness in 67 healthy young adults. We found that individual differences measured by the subjective report of body ownership are associated with the cortical thickness in the somatosensory regions, the temporo-parietal junction, the intraparietal areas, and the occipitotemporal cortex, while the proprioceptive drift is linked to the premotor area and the anterior cingulate cortex. These results are in line with functional neuroimaging studies indicating that these areas are indeed involved in processes such as cognitive-affective perspective taking, visual processing of the body, and the experience of body ownership and bodily awareness. Consequently, these individual differences in the sensation of body ownership are pronounced in both functional and structural differences.

Psychological well-being and coping strategies of elderly people during the COVID-19 pandemic in Hungary.

OBJECTIVE: During COVID-19 lockdown the enforced social isolation and other pandemic-related changes highly increased the risk of mental health problems. We aimed to discover how elderly people coped with the psychological burdens of pandemic and the social isolation in Hungary. METHODS: This study included 589 (441 females) Hungarian individuals, aged 60-83 (M = 68.1, SD = 4.46). We collected online survey data to reach a wide population of elderly. Results of hierarchical linear modelling and structural equation modelling (SEM) analyses established how the current life-changing circumstances, the intolerance of uncertainty, loneliness and social support influence the mental health (e.g. depression, anxiety, well-being) of the elderly. The model was used to explore how adaptive and maladaptive emotion regulation strategies mediated the effects. RESULTS: Findings showed that perceived change in mood, social connectedness, and quality of life was negatively affected by catastrophizing and loneliness; whereas positive refocusing and contamination fear had a positive effect. According to the SEM analysis, intolerance of uncertainty and loneliness directly affected mental health. Further, maladaptive emotion regulation strategies mediated the connection between intolerance of uncertainty, contamination fear, loneliness and mental health. Whereas adaptive emotion regulation strategy mediated the connection between social support from friends, contamination fear, loneliness and mental health. CONCLUSION: Overall, our research might help the understanding of how external and internal factors contributed to the well-being of elderly people during the COVID-19. The model can also be translated into professional interventions to develop coping strategies among elderly for the challenges of COVID-19 pandemic in their lives.

"Finding an Emotional Face" Revisited: Differences in Own-Age Bias and the Happiness Superiority Effect in Children and Young Adults.

People seem to differ in their visual search performance involving emotionally expressive faces when these expressions are seen on faces of others close to their age (peers) compared to faces of non-peers, known as the own-age bias (OAB). This study sought to compare search advantages in angry and happy faces detected on faces of adults and children on a pool of children (N = 77, mean age = 5.57) and adults (N = 68, mean age = 21.48). The goals of this study were to (1) examine the developmental trajectory of expression recognition and (2) examine the development of an OAB. Participants were asked to find a target face displaying an emotional expression among eight neutral faces. Results showed that children and adults found happy faces significantly faster than angry and fearful faces regardless of it being present on the faces of peers or non-peers. Adults responded faster to the faces of peers regardless of the expression. Furthermore, while children detected angry faces significantly faster compared to fearful ones, we found no such difference in adults. In contrast, adults detected all expressions significantly faster when they appeared on the faces of other adults compared to the faces of children. In sum, we found evidence for development in detecting facial expressions and also an age-dependent increase in OAB. We suggest that the happy face could have an advantage in visual processing due to its importance in social situations and its overall higher frequency compared to other emotional expressions. Although we only found some evidence on the OAB, using peer or non-peer faces should be a theoretical consideration of future research because the same emotion displayed on non-peers' compared to peers' faces may have different implications and meanings to the perceiver.

Disentangling the facilitating and hindering effects of threat-related stimuli - A visual search study.

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.

Internet addiction and functional brain networks: task-related fMRI study.

A common brain-related feature of addictions is the altered function of higher-order brain networks. Growing evidence suggests that Internet-related addictions are also associated with breakdown of functional brain networks. Taking into consideration the limited number of studies used in previous studies in Internet addiction (IA), our aim was to investigate the functional correlates of IA in the default mode network (DMN) and in the inhibitory control network (ICN). To observe these relationships, task-related fMRI responses to verbal Stroop and non-verbal Stroop-like tasks were measured in 60 healthy university students. The Problematic Internet Use Questionnaire (PIUQ) was used to assess IA. We found significant deactivations in areas related to the DMN (precuneus, posterior cingulate gyrus) and these areas were negatively correlated with PIUQ during incongruent stimuli. In Stroop task the incongruent_minus_congruent contrast showed positive correlation with PIUQ in areas related to the ICN (left inferior frontal gyrus, left frontal pole, left central opercular, left frontal opercular, left frontal orbital and left insular cortex). Altered DMN might explain some comorbid symptoms and might predict treatment outcomes, while altered ICN may be the reason for having difficulties in stopping and controlling overuse.

Does Threat Have an Advantage After All? - Proposing a Novel Experimental Design to Investigate the Advantages of Threat-Relevant Cues in Visual Processing.

The automatic visual attentional procession of threatening stimuli over non-threatening cues has long been a question. The so-called classical visual search task (VST) has quickly become the go-to paradigm to investigate this. However, the latest results showed that the confounding results could originate from the shortcomings of the VST. Thus, here we propose a novel approach to the behavioral testing of the threat superiority effect. We conducted two experiments using evolutionary relevant and modern real-life scenes (e.g., forest or street, respectively) as a background to improve ecological validity. Participants had to find different targets in different spatial positions (close to fovea or periphery) using a touch-screen monitor. In Experiment 1 participants had to find the two most often used exemplar of the evolutionary and modern threatening categories (snake and gun, respectively), or neutral objects of the same category. In Experiment 2 we used more exemplars of each category. All images used were controlled for possible confounding low-level visual features such as contrast, frequency, brightness, and image complexity. In Experiment 1, threatening targets were found faster compared to neutral cues irrespective of the evolutionary relevance. However, in Experiment 2, we did not find an advantage for threatening targets over neutral ones. In contrast, the type of background, and spatial position of the target only affected the detection of neutral targets. Our results might indicate that some stimuli indeed have an advantage in visual processing, however, they are not highlighted based on evolutionary relevance of negative valence alone, but rather through different associational mechanisms.

[Examination of shortened version of spider phobia and snake phobia questionnaire on Hungarian sample].

INTRODUCTION: One of the most common mental disorders is the specific phobia. Within this, the prevalence of animal phobia, such as the fear from spiders and snakes, is very high. In case of irrational fears, beyond the change in behavior (for example avoidance of the situation), a specific brain activation pattern can also be observed. However, if animal phobia is detected, it can be treated through several different therapeutic methods. There is a great need for reliable questionnaires to examine the subtypes of animal phobia. The SNAQ-12 and SPQ-12 can be used for this purpose, furthermore these questionnaires have good psychometric properties and clinical cut-off scores. The aim of the present study is therefore to examine the psychometric properties of the two questionnaires' Hungarian version. METHOD AND RESULTS: The SNAQ-12 (12 item long Snake Questionnaire, SNAQ) and the SPQ-12 (12 item long Spider Phobia Questionnaire), according to the measured sample (1071 Hungarian subject) have excellent psychometric properties (Snake Questionnaire: Cronbach alpha=0.912. Spider Questionnaire: Cronbach alpha=0.909), and are suitable for reliable testing of fear from snake and spider. CONCLUSION: The questionnaires are useful in phobia related researches and studies and can promote the clinical work, to recognize phobias and to monitor the effectiveness of therapy.

Differentiation between young adult Internet addicts, smokers, and healthy controls by the interaction between impulsivity and temporal lobe thickness.

BACKGROUND AND AIMS: Internet addiction is a non-substance-related addiction disorder with progressively growing prevalence. Internet addiction, like substance-related addictions, has been linked with high impulsivity, low inhibitory control, and poor decision-making abilities. Cortical thickness measurements and trait impulsivity have been shown to have a distinct relationship in addicts compared to healthy controls. Thus, we test whether the cortical correlates of trait impulsivity are different in Internet addicts and healthy controls, using an impulsive control group (smokers). METHODS: Thirty Internet addicts (15 females) and 60 age- and gender-matched controls (30 smokers, all young adults aged 19-28 years) were scanned using a 3T MRI scanner and completed the Barratt Impulsiveness Scale. RESULTS: Internet addicts had a thinner left superior temporal cortex than controls. Impulsivity had a significant main effect on the left pars orbitalis and bilateral insula, regardless of group membership. We identified divergent relationships between trait impulsivity and thicknesses of the bilateral middle temporal, right superior temporal, left inferior temporal, and left transverse temporal cortices between Internet addicts and healthy controls. Further analysis with smokers revealed that the left middle temporal and left transverse temporal cortical thickness change might be exclusive to Internet addiction. DISCUSSION: The effects of impulsivity, combined with a long-term exposure to some specific substance or stimuli, might result in different natures of relationships between impulsivity and brain structure when compared to healthy controls. CONCLUSION: These results may indicate that Internet addiction is similar to substance-related addictions, such that inefficient self-control could result in maladaptive behavior and inability to resist Internet use.

Internet addiction associated with right pars opercularis in females.

BACKGROUND AND AIMS: Structural differences in higher-order brain areas are common features of behavioral addictions, including Internet addiction (IA) as well. Taking into consideration the limited number of studies and methods used in previous studies on IA, our aim was to investigate the correlates of IA and the morphometry of the frontal lobes. METHODS: To observe these relationships, the high-resolution T1-weighted MR images of 144 healthy, Caucasian, university students were analyzed with volumetry and voxel-based morphometry. The Problematic Internet Use Questionnaire (PIUQ) was used to assess IA. RESULTS: We found significant correlations between PIUQ subscales and the volume of the right pars opercularis volume and gray matter mass in women. DISCUSSION AND CONCLUSION: The increased gray matter measures of this structure might be explained with the extended effort to control for the impulsive behavior in addiction, and with the increased number of social interactions via the Internet.

Short versions of two specific phobia measures: The snake and the spider questionnaires.

Zoophobias are the most prevalent form of specific phobia worldwide. Two of the most widely used measures, the Snake Questionnaire (SNAQ) and Spider Questionnaire (SPQ) are good indicators of specific fears, but researchers have recognised that shorter, yet nevertheless reliable measures are needed. Hence the aims of this research were to develop short forms of the SNAQ and SPQ using item response theory and to use receiver operating characteristic (ROC) curve analyses to determine cut-offs for use in future research. Twelve-item versions of both scales (SNAQ-12 and SPQ-12) demonstrated excellent discrimination along the latent continuum in a sample of 1354 people. The SNAQ-12 and SPQ-12 showed excellent reliability and were highly correlated with the corresponding full-length scale. The scales discriminated between participants who reported snake (3.25%) or spider (8.05%) phobia and those who did not. Further analyses revealed that non-phobic women report higher fear of both snakes and spiders than do men, but this difference was not present in phobics. These findings suggest that the SNAQ-12 and SPQ-12 have considerable strengths, including shorter assessment and scoring times, whilst retaining high reliability and potential utility as a clinical screening tool.
