Validity and reliability of electroencephalographic frontal alpha asymmetry and frontal midline theta as biomarkers for depression

Electroencephalographic (EEG) frontal alpha asymmetry (FAA) and frontal midline (FM) theta have been suggested as biomarkers for depression and anxiety, but have mostly been assessed in small and non‐clinical studies. In a clinical sample of 79 adults with depression (ICD‐10: F32), resting EEG and scales of depression (MADRS) and anxiety (HADS‐A) were measured at intake and after 3 months. FAA and FM theta values were referenced to a normative population database. Internal consistency, test‐retest reliability, and correlations with psychiatric tests were examined. Reliability was sufficient. However, FAA and FM theta values were close to the general population, and correlations with psychiatric tests were mostly small and non‐significant, with the exception of FAA on F7–F8 z‐scores and HADS‐A. We conclude that the validity of FAA and FM theta and therefore their potential as biomarkers for depression and anxiety remain unclear.     

Attentional Bias,Self-consciousness and Perfectionism in Social Phobia Before and After Cognitive-Behaviour Therapy

Attentional bias for threat words (as measured by the emotional Stroop task), selfconsciousness and perfectionism was studied in 24 patients with social phobia before and after cognitive-behaviour treatment. A total of 18 (75%) of the patients were classified as treatment responders on the basis of reduced scores for social anxiety. The treatment responders showed a significant reduction in attentional bias for social threat words, in public self-consciousness and in perfectionism. The non-responders showed an equal reduction in perfectionism; as they had a much higher level of perfectionism before treatment, however, their change only amounted to a lowering of their level of perfectionism to the level that characterized the treatment responders before treatment. The treatment responders, on the other hand, reduced their level of perfectionism to that of non-clinical samples.     

On the universality of language comprehension strategies: evidence from Turkish

A fundamental question in psycholinguistic research concerns the universality of comprehension strategies. We investigated this issue by examining the so-called "subject preference" in Turkish, a language which allows for a natural (unmarked) object reading of an initial ambiguous argument. Using event-related brain potentials (ERPs), we observed increased processing difficulty in the form of a broadly distributed positivity when an initial ambiguous argument was disambiguated towards an object reading. This effect was independent of the animacy (i.e. semantic subject prototypicality) of the ambiguous argument. Our results therefore speak in favour of a universal tendency to interpret the first argument encountered as the "subject" of the clause, even in languages providing no obvious structural motivation for such a strategy. However, we argue that the underlying explanation for this preference must be modified in accordance with cross-linguistic considerations.     

PRIEST AND NAGEL ON BEING SOMEONE: A REFUTATION OF PHYSICALISM

Physicalism entails that a possible world which is a minimal physical duplicate of the actual world be a duplicate simpliciter of the actual world. Because what I really am is not a particular human being, there exists a minimal physical duplicate of the actual world which is not a duplicate simpliciter of the actual world. Therefore, physicalism is false.     

Cross‐group friendships and outgroup attitudes among Turkish–Kurdish ethnic groups: does perceived interethnic conflict moderate the friendship‐attitude link?

We investigated associations between cross‐group friendships, perceived interethnic conflict, and outgroup attitudes in the context of intractable Turkish–Kurdish conflict in Turkey. Measures of cross‐group friendship quantity, perceived conflict, outgroup attitudes, multiculturalism, and outgroup responsibility for conflict were completed by Turkish (N = 320) and Kurdish (N = 153) participants (M_age = 21, 156 males, 317 females). Both cross‐group friendships and perceived conflict were related to outcome variables. While cross‐group friendships were beneficial for both groups’ outgroup attitudes when perceived conflict was lower; when perceived conflict level was higher, positive associations between friendships and attitudes became non‐significant for the Turkish group and negative for the Kurdish group. Implications of the findings for the intergroup contact theory have been discussed.     

The role of leadership perception as a mediator between managers’ self-monitoring and subordinate attitudes

Although the role of social cognition in leadership perception has been emphasized frequently in recent years, research using this approach in an organizational context is rare. This study investigated subordinates’ perceptions of their managers as leaders (that is, to what extent they perceive their manager as a leader) as a potential mediating factor explaining the relationship between managers’ self-monitoring and their subordinates’ attitudes toward their organizations. The study was carried out with middle-level managers (N = 64) and their subordinates (N = 210) from various business organizations in Turkey. Results indicate that subordinates’ leadership perceptions of their managers mediate the relationship between managers’ self-monitoring and their subordinates’ affective and normative organizational commitment. These results provide insight into some of the antecedents and outcomes of leadership perception.     

Mothers' Reactions to Preschoolers' Proactive and Reactive Aggressive Behaviours

The present study was designed to examine mothers' emotional reactions, causal attributions, and socialization strategies in response to preschool children's engagement in proactive and reactive physical aggression with peers during free play at school. Participants were 84 mothers (M_age = 31.83, SD = 4.48) with preschool‐aged children (M_age = 4.92, SD = 0. 97), residing in Ankara, Turkey. Supporting our expectations, mothers reacted with negative emotions to both functions of aggressive behaviours, with less anxiety, disappointment, embarrassment, and guilt for reactive aggression. They also believed that reactive aggression is more contextually dependent and intentional and reported more indirect (e.g., asking the child, teacher, or other children to find out more about the situation and aggressive episode) and other‐oriented strategies (e.g., telling the other child to behave properly) to address these behaviours. Overall, our findings suggest that Turkish mothers' feelings, perceptions, and socialization approaches to childhood aggression vary depending on the functions of aggression, and mothers perceive preschool‐aged children's engagement in reactive aggression in the school setting as relatively more acceptable than proactive aggression.

Factor solutions of the Social Phobia Scale (SPS) and the Social Interaction Anxiety Scale (SIAS) in a Swedish population

Culturally validated rating scales for social anxiety disorder (SAD) are of significant importance when screening for the disorder, as well as for evaluating treatment efficacy. This study examined construct validity and additional psychometric properties of two commonly used scales, the Social Phobia Scale and the Social Interaction Anxiety Scale, in a clinical SAD population (n?=?180) and in a normal population (n?=?614) in Sweden. Confirmatory factor analyses of previously reported factor solutions were tested but did not reveal acceptable fit. Exploratory factor analyses (EFA) of the joint structure of the scales in the total population yielded a two-factor model (performance anxiety and social interaction anxiety), whereas EFA in the clinical sample revealed a three-factor solution, a social interaction anxiety factor and two performance anxiety factors. The SPS and SIAS showed good to excellent internal consistency, and discriminated well between patients with SAD and a normal population sample. Both scales showed good convergent validity with an established measure of SAD, whereas the discriminant validity of symptoms of social anxiety and depression could not be confirmed. The optimal cut-off score for SPS and SIAS were 18 and 22 points, respectively. It is concluded that the factor structure and the additional psychometric properties of SPS and SIAS support the use of the scales for assessment in a Swedish population.     

The Impact of Perceived Social Norms,Gender, and Intergroup Anxiety on the Relationship Between Intergroup Contact and Ethnic Attitudes of Adolescents1

This study addressed the impact of perceived familial and peer norms, gender, and intergroup anxiety on the relationship between the quality of inter‐ethnic contact and blatant and subtle ethnic attitudes of adolescents. With regard to the main focus of the study—the moderating effect of perceived norms—familial norms had a gender‐specific impact on the relationship between contact quality and subtle attitudes. Further, both familial and peer norms predicted the blatant and subtle attitudes of youth. Contact quantity had no effect, but contact quality had strong effects on both attitudes. Intergroup anxiety had direct and mediating effects on both kinds of attitudes. The results are discussed in relation to social‐contextual and developmental factors affecting the formation of ethnic attitudes.
