However, little is known about the quality of life (QoL) of this group of parents. Therefore, this cross-sectional study aimed to provide a comprehensive analysis of parental QoL among parents seeking treatment for their child's abdominal pain. Methods: 133 parents of 7-13-year-old children diagnosed with FAP reported on their health-related QoL (HRQoL), as assessed by the SF-12, and on caregiver-related QoL, as assessed by two CHQ-PF50 scales (emotional impact, time impact). T tests were used to compare the parents' scores on these measures with reference scores. Subgroups which were at risk of impairment were defined by cut-off scores. Determinants of parental QoL were identified by hierarchical regression analyses. Results: While the parents showed significantly poorer mental health compared to population-based reference samples (d = 0.33-0.58), their physical health did not differ. However, parents were severely strained with respect to the time impact and emotional impact of their child's health (d = 0.33-1.58). While 12.7-27.9\% of the parents were at risk of poor HRQoL, 60.6-70.1\% were highly strained due to the demands of their role as caregivers. Physical and mental health were best explained by parents' psychiatric symptoms, while parents' perception of their child's impairment additionally determined the high time and emotional impact. Conclusions: Physical HRQoL is not impaired in the majority of parents seeking treatment for their child's functional abdominal pain. However, the time demands and worries due to the child's pain deserve specific attention. Psychosocial interventions for a child's FAP should include information provided to the parents about coping with time constraints and emotional impact.

The present study focused on the relation between negative emotions and arithmetical performance in children with and without developmental dyscalculia (DD) using an affective priming task. Previous findings suggested that arithmetic performance is influenced if an affective prime precedes the presentation of an arithmetic problem. In children with DD specifically, responses to arithmetic operations are supposed to be facilitated by both negative and mathematics-related primes (= negative math priming effect). We investigated mathematical performance, math anxiety, and the domain-general abilities of 172 primary school children (76 with DD and 96 controls). All participants also underwent an affective priming task which consisted of the decision whether a simple arithmetic operation (addition or subtraction) that was preceded by a prime (positive/negative/neutral or mathematics-related) was true or false. Our findings did not reveal a negative math priming effect in children with DD. Furthermore, when considering accuracy levels, gender, or math anxiety, the negative math priming effect could not be replicated. However, children with DD showed more math anxiety when explicitly assessed by a specific math anxiety interview and showed lower mathematical performance compared to controls. Moreover, math anxiety was equally present in boys and girls, even in the earliest stages of schooling, and interfered negatively with performance. In conclusion, mathematics is often associated with negative emotions that can be manifested in specific math anxiety, particularly in children with DD. Importantly, present findings suggest that in the assessed age group, it is more reliable to judge math anxiety and investigate its effects on mathematical performance explicitly by adequate questionnaires than by an affective math priming task.}, language = {en} } @misc{GropalisBailerWecketal.2018, author = {Gropalis, Maria and Bailer, Josef and Weck, Florian and Witth{\"o}ft, Michael}, title = {Optimierung von Expositionstherapie bei pathologischen Krankheits{\"a}ngsten}, series = {Psychotherapeut}, volume = {63}, journal = {Psychotherapeut}, number = {3}, publisher = {Springer}, address = {New York}, issn = {0935-6185}, doi = {10.1007/s00278-018-0285-1}, pages = {188 -- 193}, year = {2018}, abstract = {Pathologische Krankheits{\"a}ngste wurden bislang nach ICD und DSM prim{\"a}r als somatoforme St{\"o}rung bzw. als somatische Belastungsst{\"o}rung klassifiziert.

Baseline empathy scores were obtained before consultation, relational empathy was rated by SP after consultation. Multilevel logistic regression modelled the probability of mimicry occurrence, controlling for baseline empathy and clinical experience. ANCOVA compared group differences on relational empathy and consultation smoothness. Results: Instructed mimicry lasted longer than spontaneous mimicry. Mimicry was marginally related to improved relational empathy. SP felt being treated more like a whole person during consultations with spontaneous mimicry. Clinicians who displayed spontaneous mimicry felt consultations went more smoothly. Conclusion: The experimental approach improved our understanding of how non-verbal emotional mimicry contributed to relational empathy development during consultations.

Methods: The behavior of 164 mother-infant dyads during the still-face situation was filmed at six months postpartum and coded into three dyadic patterns: 1) both positive, 2) infant protesting-mother positive, and 3) infant protesting-mother negative. PS exposure was assessed prenatally according to psychological measures (i.e., psychopathological, perceived and psychosocial PS; n = 164) and HPA axis activity measures (maternal salivary cortisol, i.e., cortisol decline and area under the curve with respect to ground (AUCg); n = 134). Results: Mother-infant dyads in both the high- and low-stress groups showed decreasing positive and increasing negative dyadic behavior in the reunion episode, which is associated with the well-known "still-face" and "carry-over" effect. Furthermore, mother-infant dyads with higher psychosocial PS exhibited significantly more positive dyadic behavior than the low psychosocial PS group in the first play episode, but not in the reunion episode. Similarly, mother-infant dyads with high HPA axis activity (i.e. high AUCg) but steeper diurnal cortisol decline (i.e. cortisol decline) displayed significantly less negative behavior in the reunion episode than dyads with low HPA axis activity.

Using five nonclinical samples in two studies (total N = 602), we investigated the effect of facets of grandiose narcissism on aspects of socioemotional cognition across measures of affective and cognitive empathy, Theory of Mind, and emotional intelligence, while also controlling for general reasoning ability. Across both studies, agentic facets of narcissism were found to be positively related to perceived SECA, whereas antagonistic facets of narcissism were found to be negatively related to perceived SECA. However, both narcissism facets were negatively related to actual SECA. Exploratory condition-based regression analyses further showed that agentic narcissists had a higher directed discrepancy between perceived and actual SECA: They self-enhanced their socio-emotional capacities.

The present study examined parental mental health and single parenthood using data from family law proceedings. The role of the fathers has been understudied and the few existing studies yielded contradictory results with respect to fathers' involvement as risk or protective factor. Therefore, the study included both fathers' data and mothers' data. A total of 220 child protection court files with 343 affected children were coded using a category system. Parental mental health was coded as parental functioning in daily life and was significantly associated with the court outcome. Multilevel mediation analyses showed a significant indirect effect of maternal functioning on the intrusiveness of the court decisions via child maltreatment. Single motherhood moderated the effect: The indirect effect was more pronounced for single mothers. This study contributes to a better understanding of the population getting before court and the judicial process.

The goal of the present study was to thoroughly disentangle different conceptualizations of self-esteem and test opposing classical theories on (i) the stability and (ii) the direction of mutual influence of these different forms of self-esteem. We analysed two-year longitudinal data from participants (N=644 at T1, N=241 at T2) with an average age of 47.0years (SD=12.4). Analyses using a latent variable approach revealed that the domains of self-esteem were relatively stable in terms of rank order and mean levels. In fact, the size of the stability coefficients was comparable to that of other trait measures that have been reported in the literature and paralleled the stability observed for global self-esteem. Results did not provide support for either top-down or bottom-up effects between domain-specific and global self-esteem.

The present study focused on the relation between negative emotions and arithmetical performance in children with and without developmental dyscalculia (DD) using an affective priming task. Previous findings suggested that arithmetic performance is influenced if an affective prime precedes the presentation of an arithmetic problem. In children with DD specifically, responses to arithmetic operations are supposed to be facilitated by both negative and mathematics-related primes (= negative math priming effect). We investigated mathematical performance, math anxiety, and the domain-general abilities of 172 primary school children (76 with DD and 96 controls). All participants also underwent an affective priming task which consisted of the decision whether a simple arithmetic operation (addition or subtraction) that was preceded by a prime (positive/negative/neutral or mathematics-related) was true or false. Our findings did not reveal a negative math priming effect in children with DD. Furthermore, when considering accuracy levels, gender, or math anxiety, the negative math priming effect could not be replicated. However, children with DD showed more math anxiety when explicitly assessed by a specific math anxiety interview and showed lower mathematical performance compared to controls. Moreover, math anxiety was equally present in boys and girls, even in the earliest stages of schooling, and interfered negatively with performance. In conclusion, mathematics is often associated with negative emotions that can be manifested in specific math anxiety, particularly in children with DD. Importantly, present findings suggest that in the assessed age group, it is more reliable to judge math anxiety and investigate its effects on mathematical performance explicitly by adequate questionnaires than by an affective math priming task.}, language = {en} } @misc{MoraskeWyschkonPoltzetal.2018, author = {Moraske, Svenja and Wyschkon, Anne and Poltz, Nadine and Kucian, Karin and Aster, Michael and Esser, G{\"u}nter}, title = {LRS-Pr{\"a}vention bei Risikokindern}, series = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, journal = {Postprints der Universit{\"a}t Potsdam : Humanwissenschaftliche Reihe}, number = {672}, issn = {1866-8364}, doi = {10.25932/publishup-44142}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-441426}, pages = {171 -- 183}, year = {2018}, abstract = {Fragestellung: Ziel der Studie war die {\"U}berpr{\"u}fung der Wirksamkeit einer vorschulischen F{\"o}rderung der phonologischen Bewusstheit und der Buchstaben-Laut-Verkn{\"u}pfung bei Kindern mit einem Risiko f{\"u}r die Entwicklung einer Lese-Rechtschreibst{\"o}rung (LRS) unter Bedingungen, die sich am Alltag der Kindertagesst{\"a}tten orientierten und somit auch bei einem breiten Einsatz des Programms eine relativ {\"o}konomische Variante darstellen.

The similarity in time-frames during which perceptual narrowing seems to occur in the domains of speech and face perception has led some researchers to hypothesize that the perceptual narrowing in these domains could be driven by shared domain-general processes. To explore this hypothesis, we tested 53 Caucasian 9-month-old infants from monolingual German households on their ability to discriminate among non-native Cantonese speech tones, as well among same-race German faces and other-race Chinese faces. We tested the infants using an infant-controlled habituation-dishabituation paradigm, with infants' preferences for looking at novel stimuli versus the habituated stimuli (dishabituation scores) acting as indicators of discrimination ability. As expected for their age, infants were able to discriminate between same-race faces, but not between other-race faces or non-native speech tones. Most interestingly, we found that infants' dishabituation scores for the non-native speech tones and other-race faces showed significant positive correlations, while the dishabituation scores for non-native speech tones and same-race faces did not.

For example, adding repeated numbers (so-called tie problems, e.g., 2 + 2) not only has a speed and accuracy advantage over adding different numbers (e.g., 1 + 3) but may also lead to under-representation of the result relative to a standard value (Charras et al., 2012, 2014). Does the tie advantage merely reflect easier encoding or retrieval compared to non-ties, or also a distorted result representation? To answer this question, 47 healthy adults performed two tasks, both of which indicated under-representation of tie results: In a result-to-position pointing task (Experiment 1) we measured the spatial mapping of numbers and found a left-bias for tie compared to non-tie problems. In a result-to-line-length production task (Experiment 2) we measured the underlying magnitude representation directly and obtained shorter lines for tie-compared to non-tie problems. These observations suggest that the processing benefit of tie problems comes at the cost of representational reduction of result meaning.

Here we apply this rationale to the domain of numerical cognition in order to explore the differences between fast and slow arithmetic performance, and to further study the role of spatial-numerical associations during mental arithmetic. We presented 30 healthy adults simultaneously with visual displays containing four numbers and with auditory addition and subtraction problems. Analysis of eye movements revealed that participants look spontaneously at the numbers they currently process (operands, solution). Faster performance was characterized by shorter latencies prior to fixating the relevant numbers and fewer revisits to the first operand while computing the solution. These signatures of superior task performance were more pronounced for addition and visual numbers arranged in ascending order, and for subtraction and numbers arranged in descending order (compared to the opposite pairings). Our results show that the visual number world-paradigm provides on-line access to the mind during mental arithmetic, is able to capture variability in arithmetic performance, and is sensitive to visual layout manipulations that are otherwise not reflected in response time measurements.}, language = {en} } @article{LiWangMoetal.2018, author = {Li, Nan and Wang, Suiping and Mo, Luxi and Kliegl, Reinhold}, title = {Contextual constraint and preview time modulate the semantic preview effect}, series = {The quarterly journal of experimental psychology}, volume = {71}, journal = {The quarterly journal of experimental psychology}, number = {1}, publisher = {Sage Publ.}, address = {London}, issn = {1747-0218}, doi = {10.1080/17470218.2017.1310914}, pages = {241 -- 249}, year = {2018}, abstract = {Word recognition in sentence reading is influenced by information from both preview and context. Recently, semantic preview effect (SPE) was observed being modulated by the constraint of context, indicating that context might accelerate the processing of semantically related preview words. Besides, SPE was found to depend on preview time, which suggests that SPE may change with different processing stages of preview words. Therefore, it raises the question of whether preview time-dependent SPE would be modulated by contextual constraint. In this study, we not only investigated the impact of contextual constraint on SPE in Chinese reading but also examined its dependency on preview time. The preview word and the target word were identical, semantically related or unrelated to the target word. The results showed a significant three-way interaction: The SPE depended on contextual constraint and preview time. In separate analyses for low and high contextual constraint of target words, the SPE significantly decreased with an increase in preview duration when the target word was of low constraint in the sentence. The effect was numerically in the same direction but weaker and statistically nonsignificant when the target word was highly constrained in the sentence. The results indicate that word processing in sentences is a dynamic process of integrating information from both preview (bottom-up) and context (top-down).}, language = {en} } @article{SelenkoBerkersCarteretal.2018, author = {Selenko, Eva and Berkers, Hannah and Carter, Angela and Woods, Stephen A. and Otto, Kathleen and Urbach, Tina and De Witte, Hans}, title = {On the dynamics of work identity in atypical employment}, series = {European journal of work and organizational psychology : the official journal of The European Association of Work and Organizational Psychology}, volume = {27}, journal = {European journal of work and organizational psychology : the official journal of The European Association of Work and Organizational Psychology}, number = {3}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {1359-432X}, doi = {10.1080/1359432X.2018.1444605}, pages = {324 -- 334}, year = {2018}, abstract = {Starting from the notion that work is an important part of who we are, we extend existing theory making on the interplay of work and identity by applying them to (so called) atypical work situations. Without the contextual stability of a permanent organizational position, the question "who one is" will be more difficult to answer. At the same time, a stable occupational identity might provide an even more important orientation to one's career attitudes and goals in atypical employment situations. So, although atypical employment might pose different challenges on identity, identity can still be a valid concept to assist the understanding of behaviour, attitudes, and well-being in these situations. Our analysis does not attempt to "reinvent" the concept of identity, but will elaborate how existing conceptualizations of identity as being a multiple (albeit perceived as singular), fluid (albeit perceived as stable), and actively forged (as well as passively influenced) construct that can be adapted to understand the effects of atypical employment contexts. Furthermore, we suggest three specific ways to understand the longitudinal dynamics of the interplay between atypical employment and identity over time: passive incremental, active incremental, and transformative change. We conclude with key learning points and outline a few practical recommendations for more research into identity as an explanatory mechanism for the effects of atypical employment situations.}, language = {en} } @article{SchwarzReike2018, author = {Schwarz, Wolfgang and Reike, Dennis}, title = {The number-weight illusion}, series = {Psychonomic bulletin \& review : a journal of the Psychonomic Society}, volume = {26}, journal = {Psychonomic bulletin \& review : a journal of the Psychonomic Society}, number = {1}, publisher = {Springer}, address = {New York}, issn = {1069-9384}, doi = {10.3758/s13423-018-1484-z}, pages = {332 -- 339}, year = {2018}, abstract = {When objects are manually lifted to compare their weight, then smaller objects are judged to be heavier than larger objects of the same physical weights: the classical size-weight illusion (Gregory, 2004).

A dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis in offspring has been suggested as an important mechanism. However, the impact of prenatal stress on stress reactivity in preschool-aged children is not yet well understood. This is partly due to the fact that for this age group there is no stress test as well established as for older children and adults. In the present work a previously published stress test (Kryski et al., 2011) was evaluated in a large sample of 45-month-old children (n = 339). Furthermore, the relation between measures of prenatal maternal stress and cortisol reactivity was investigated. Prenatal stress was defined as psychopathology (self-report available for n = 339; expert-rating available for a subsample of n = 246) and perceived stress (n = 244) during pregnancy. The stress paradigm elicited significant increases in salivary cortisol 30 and 40 min after the test, and 60.8\% of the children were classified as responders. Lower cortisol levels after the stress test were observed in the group of children with prenatal stress defined as maternal psychopathology (both self-reported and expert-rated). Maternal perceived stress as a continuous measure was not significantly associated with cortisol levels. However, when comparing children in the highest quartile of maternal perceived stress to all other children, significantly lower cortisol values were observed in the prenatally stressed group. The present study confirms the paradigm by Kryski et al. as an effective stress test for preschool-aged children. Moreover, it provides further evidence that prenatal stress impacts HPA axis reactivity.

From our perspective of motivational competence, affective and cognitive processes work together rather than oppose each other in self-regulation, rendering effortless rather than effortful goal pursuit as the hallmark of efficient human action. A precondition for such motive- and self-congruent goal pursuits is that individuals have insight into their basic preferences and (can) act accordingly.

To further study the potential association, we applied a novel technique, the non-invasive transcutaneous vagus nerve stimulation (tVNS), which is speculated to increase noradrenaline levels. Using a within-subject cross-over design, 20 healthy participants received continuous tVNS and sham stimulation on two consecutive days (stimulation counterbalanced across participants) while performing a visual oddball task. During stimulation, oval non-targets (standard), normal-head (easy) and rotated-head (difficult) targets, as well as novel stimuli (scenes) were presented. As an indirect marker of noradrenergic activation we also collected salivary alpha-amylase (sAA) before and after stimulation. Results showed larger P3b amplitudes for target, relative to standard stimuli, irrespective of stimulation condition. Exploratory post hoc analyses, however, revealed that, in comparison to standard stimuli, easy (but not difficult) targets produced larger P3b (but not P3a) amplitudes during active tVNS, compared to sham stimulation. For sAA levels, although main analyses did not show differential effects of stimulation, direct testing revealed that tVNS (but not sham stimulation) increased sAA levels after stimulation. Additionally, larger differences between tVNS and sham stimulation in P3b magnitudes for easy targets were associated with larger increase in sAA levels after tVNS, but not after sham stimulation. Despite preliminary evidence for a modulatory influence of tVNS on the P3b, which may be partly mediated by activation of the noradrenergic system, additional research in this field is clearly warranted. Future studies need to clarify whether tVNS also facilitates other processes, such as learning and memory, and whether tVNS can be used as therapeutic tool.}, language = {en} } @article{SixtusLindemannFischer2018, author = {Sixtus, Elena and Lindemann, Oliver and Fischer, Martin H.}, title = {Stimulating numbers}, series = {Psychological research : an international journal of perception, attention, memory, and action}, volume = {84}, journal = {Psychological research : an international journal of perception, attention, memory, and action}, number = {1}, publisher = {Springer}, address = {Heidelberg}, issn = {0340-0727}, doi = {10.1007/s00426-018-0982-y}, pages = {152 -- 167}, year = {2018}, abstract = {Finger counting is one of the first steps in the development of mature number concepts.
