The effects of stimulus complexity on the preattentive processing of self-generated and nonself voices: An ERP study

The ability to differentiate one’s own voice from the voice of somebody else plays a critical role in successful verbal self-monitoring processes and in communication. However, most of the existing studies have only focused on the sensory correlates of self-generated voice processing, whereas the effects of attentional demands and stimulus complexity on self-generated voice processing remain largely unknown. In this study, we investigated the effects of stimulus complexity on the preattentive processing of self and nonself voice stimuli. Event-related potentials (ERPs) were recorded from 17 healthy males who watched a silent movie while ignoring prerecorded self-generated (SGV) and nonself (NSV) voice stimuli, consisting of a vocalization (vocalization category condition: VCC) or of a disyllabic word (word category condition: WCC). All voice stimuli were presented as standard and deviant events in four distinct oddball sequences. The mismatch negativity (MMN) ERP component peaked earlier for NSV than for SGV stimuli. Moreover, when compared with SGV stimuli, the P3a amplitude was increased for NSV stimuli in the VCC only, whereas in the WCC no significant differences were found between the two voice types. These findings suggest differences in the time course of automatic detection of a change in voice identity. In addition, they suggest that stimulus complexity modulates the magnitude of the orienting response to SGV and NSV stimuli, extending previous findings on self-voice processing.     

It’s up to you: The Influence of Sports Participation,Academic Performances and Demo-Behavioral Characteristics on University students’ Life Satisfaction

This paper investigates university students’ life satisfaction by measuring six life satisfaction components (family life satisfaction, social life satisfaction, satisfaction with the university experience, satisfaction with oneself, satisfaction with the place of residence, satisfaction with the overall life) among different students’ groups. Life satisfaction is measured using Brief Multi-Dimensional Students’ Life Satisfaction Scale (BMSLSS). A cross-sectional approach was taken to examine differences among identified students’ groups according to: academic performance (by GPA and status of funding), demographic and behavioral characteristics (by gender, body mass index, smoking and alcohol consumption) and features related to physical activity (by weekly time spent in physical activity in hours and group of sport engaged in). Research is conducted among 507 students at the Faculty of Organizational Sciences, University of Belgrade, Serbia. Man Whitney and Kruskal Wallis test were performed for pairwise comparison using Bonferroni correction. The results show statistically significant differences in the following components: satisfaction with family life (within gender group), satisfaction with social life (within sex and smoking groups), satisfaction with the university experience (within sex, smoking, alcohol consumption, GPA and scholarship/funding status groups), satisfaction with oneself (within GPA, financial status, alcohol consumption and type of sport groups), satisfaction with the place of residence (within GPA, scholarship/funding status, time spent in physical activities and body mass index) and satisfaction with the overall life (within gender and alcohol consumption groups). This paper has both theoretical and practical influence on contemporary life satisfaction field of knowledge, particularly in university students’ population.     

Are go/no-go tasks preferable to two-choice tasks in response time experiments with older adults?

Recent research has shown that, in response time (RT) tasks, the go/no-go response procedure produces faster (and less noisy) RTs and fewer errors than the two-choice response procedure in children, although these differences are substantially smaller in college-aged adults. Here we examined whether the go/no-go procedure can be preferred to the two-choice procedure in RT experiments with older adults (i.e. another population with slower and more error-prone responding than college-aged individuals). To that end, we compared these response procedures in two experiments with older adults (M_age?=?83 years): a visual word recognition task (lexical decision) and a perceptual task (numerosity discrimination). A group of young adults (M_age?=?31 years) served as a control. In the lexical decision experiment, results showed a go/no-go advantage in the mean RTs and in the error rates for words; however, this was not accompanied by less noisy RT data. The magnitude of the word-frequency effect was similar in the two response procedures. The numerosity discrimination experiment did not reveal any clear differences across response procedures, except that the RTs were noisier in the go/no-go procedure. Therefore, we found no compelling reasons why the go/no-go procedure should be preferred over the two-choice procedure in RT experiments with older adults.     

Multiproblem Families Referred to Youth Mental Health: What's in a Name?

The purpose of this study was threefold, namely (1) to differentiate between multiproblem families and control families on characteristics and processes within the family based on a theoretical framework, (2) to identify multiproblem families by establishing cut‐off scores on various questionnaires, and (3) to categorize multiproblem families into subtypes by cluster analyses. Various questionnaires were administered to multiproblem families (n = 85) and control families (n = 150). Results showed that what we propose to refer to as multiproblem families present a broad range of problems on seven domains: (1) child factors, (2) parental factors, (3) childrearing problems (inadequate or inconsistent parenting), (4) family functioning problems, (5) contextual problems, (6) social network problems, and (7) mental health care problems. Further, reliable cut‐off scores were established for various questionnaires. Finally, three types of families were found: (1) community‐problem families, (2) multiproblem families, and (3) child‐focused mild‐problem families. This paper looks to advance an evidence‐based definition and assessment of “multiproblem families” suggesting the possible value of defining and assessing multiproblem families in relation to these seven dimensions. Moreover, the classification of multiproblem families stresses the importance of providing tailored treatments.

Don’t Talk About the Elephant: Silence and Ethnic Boundaries in Postwar Bosnia-Herzegovina

In December 1995, the guns fell silent on Bosnia-Herzegovina and so did much dialogue. Silence is omnipresent in this postwar society: People conceal their suffering; they remain silent about their potential responsibility and guilt and—in interethnic encounters—the violent past is often wholly screened out. Drawing on a literature analysis as well as own interviews and ethnographic observations conducted in Bosnia-Herzegovina since 2007, the article focuses on the interplay between silence and the constitution of ethnic boundaries. In accordance with the literature, it argues that silencing in-group atrocities reinforces the boundaries between former enemies by strengthening ethnically biased collective memories. However, existing research also suggest that not speaking about war in interethnic encounters most likely contributes to the integration of Bosnian society because it enables members of different ethnic communities to interact ‘peacefully’ in everyday life, thereby creating ‘new’ realities within which ethnic boundaries become less important. This conclusion assumes that silencing necessarily leads to forgetting. The following paper challenges this perception and argues that silence about war and the avoidance of conflict in interethnic communication can, in fact, also promote a further consolidation of ethnic boundaries. When conversations about past realities only take place between like-minded people, the likely result is that their pre-existing shared perspective on this reality will become solidified. In other words, silencing war in interethnic encounters impedes any potential revision or restructuring of interethnic relations and therefore stabilises the boundaries between ethnic groups.     

The Relation Between Factual and Counterfactual Conditionals

What is the relation between factual conditionals: If A happened then B happened, and counterfactual conditionals: If A had happened then B would have happened? Some theorists propose quite different semantics for the two. In contrast, the theory of mental models and its computer implementation interrelates them. It postulates that both can have a priori truth values, and that the semantic bases of both are possibilities: states that are possible for factual conditionals, and that were once possible but that did not happen for counterfactual conditionals. Two experiments supported these relations. Experiment 1 showed that, like factual conditionals, certain counterfactuals are true a priori, and others are false a priori. Experiment 2 replicated this result and showed that participants selected appropriate paraphrases, referring, respectively, to real and to counterfactual possibilities, for the two sorts of conditional. These results are contrary to alternative accounts of conditionals.     

Are brand names special words? Letter visual-similarity affects the identification of brand names,but not common words

Brand names are often considered a special type of words of special relevance to examine the role of visual codes during reading: unlike common words, brand names are typically presented with the same letter-case configuration (e.g., IKEA, adidas). Recently, Pathak et al. (European Journal of Marketing, 2019, 53 , 2109) found an effect of visual similarity for misspelled brand names when the participants had to decide whether the brand name was spelled correctly or not (e.g., tacebook [baseword: facebook] was responded more slowly and less accurately than xacebook). This finding is at odds with both orthographically based visual-word recognition models and prior experiments using misspelled common words (e.g., viotin [baseword: violin ] is identified as fast as viocin ). To solve this puzzle, we designed two experiments in which the participants had to decide whether the presented item was written correctly. In Experiment 1, following a procedure similar to Pathak et al. (European Journal of Marketing, 2019, 53 , 2109), we examined the effect of visual similarity on misspelled brand names with/without graphical information (e.g., anazon vs. atazon [baseword: amazon ]). Experiment 2 was parallel to Experiment 1, but we focused on misspelled common words (e.g., anarillo vs. atarillo ; baseword: amarillo [yellow in Spanish]). Results showed a sizeable effect of visual similarity on misspelled brand names – regardless of their graphical information, but not on misspelled common words. These findings suggest that visual codes play a greater role when identifying brand names than common words. We examined how models of visual-word recognition can account for this dissociation.     

Attentional Processing of Threat in Bipolar Disorder: Going Beyond Mood-Congruency

Emotional processing in bipolar disorder (BD) entails a complex attentional pattern not merely restricted to happy or sad biases, but also directed towards threatening information. This study examined threat-related bias on attentional orienting when participants were not instructed about the presentation of emotional stimuli (i.e., implicit instructions). An emotional dot-probe task in which an emotional face (i.e., threat, sad, happy) is simultaneously displayed with a neutral face was applied to BD individuals in their different episodes: mania (n?=?26), depression (n?=?24), and euthymia (n?=?28) as well as to a group of healthy controls (n?=?28). Symptomatic BD patients (i.e., in a manic or depressive episode) showed an attentional orienting bias toward threatening faces but not for happy or sad faces, while euthymic BD patients did not exhibit any attentional bias for emotional stimuli. A bias toward happy faces was found in the control group. Threat-related bias was not related to the severity of affective and anxiety symptoms in BD. When attention is not explicitly directed to emotional information, threat-related bias may characterize attentional orienting during mania and depression, but may be attenuated during euthymia.
