Left ear (right temporal hemisphere) advantage and left temporal hemispheric dysfunction in schizophrenia.

In this study, to investigate the right or left ear advantages in psychiatric patients. the durations of hearing for right and left ears were assessed in 61 psychiatric patients, 26 with schizophrenia, 17 with depressive disorder, 13 with bipolar affective disorder, and 5 with brief psychotic disorder, plus 24 controls. Diagnoses were made on the basis of information provided from clinical interviews and the Structured Clinical Interview for DSM-IV (SCID). Schizophrenia was associated with a left ear advantage, and both depressive disorder and brief psychotic disorder were associated with right ear advantage as well as controls. These results suggest that their schizophrenia may be associated with a left temporal lobe dysfunction.

Lesion-symptom mapping of language impairments in people with brain tumours: The influence of linguistic stimuli

People with tumours in specific brain sites might face difficulties in tasks with different linguistic material. Previous lesion-symptom mapping studies (VLSM) demonstrated that people with tumours in posterior temporal regions have more severe linguistic impairments. However, to the best of our knowledge, preoperative performance and lesion location on tasks with different linguistic stimuli have not been examined. In the present study, we performed VLSM on 52 people with left gliomas to examine whether tumour distribution differs depending on the tasks of the Aachen Aphasia Test. The VLSM analysis revealed that single-word production (e.g. object naming) was associated with the inferior parietal lobe and that compound and sentence production were additionally associated with posterior temporal gyri. Word repetition was affected in people with tumours in inferior parietal areas, whereas sentence repetition was the only task to be associated with frontal regions. Subcortically, word and sentence production were found to be affected in people with tumours reaching the arcuate fasciculus, and compound production was primarily associated with tumours affecting the inferior longitudinal and inferior fronto-occipital fasciculus. Our work shows that tasks with linguistic stimuli other than single-word naming (e.g. compound and sentence production) relate to additional cortical and subcortical brain areas. At a clinical level, we show that tasks that target the same processes (e.g. repetition) can have different neural correlates depending on the linguistic stimuli used. Also, we highlight the importance of left temporoparietal areas.     

Culture and Social Structure: Identity in Turkey

Using a historical and biographical perspective, this paper examines the structural elements and cultural signs of contemporary social events and problems in Turkey in order to understand their basic features. Hermeneutics is used in order to understand contemporary Turkey by way of its historical background and prominent biographies. Two basic epic texts were interpreted using Gadamarian hermeneutics with the help of key concepts such as gaza¹ and gaza cult. Semiotics is used to examine key concepts as binary opposites. Dialectics is used to understand these concepts as the unity of binary opposites coexisting at the same time and place. It is concluded that the contemporary cultural values and biographies explored are linked to their historical past and Islam seems to be more influential on hybrid identities than on ethnic status.     

Whatever? The effect of social exclusion on adopting persuasive messages

The aversive state of social exclusion can result in a broad range of cognitive deficits. Being unable or unmotivated to process relevant information, we assumed that social exclusion would also affect the success of persuasive attempts. We hypothesized that socially excluded people would adopt attitudes regardless of persuasion quality. In three studies using different manipulations of social exclusion and persuasion, we showed that participants who were socially excluded adopted persuasive messages regardless of argument quality. In contrast, this undifferentiated response was not shown by socially included participants who were more persuaded by high- compared to low-quality arguments. In Study 3, we moreover revealed that this pattern could only be replicated in reliable situations—that is, when the communicator appeared credible. These findings support the assumption that social exclusion can lead to reduced processing of information.     

A Picture Database for Verbs and Nouns with Different Action Content in Turkish

In this study we present a picture database of 160 nouns and 160 verbs. All verbs and nouns are divided into two groups as action and non-action words. Age of acquisition, familiarity, imageability, name agreement and complexity norms are reported alongside frequency, word length and morpheme count for each word. Data were collected from 600 native Turkish adults in total. The results show that although several measures have weak correlations with each other, only age of acquisition had moderate downhill relationships with familiarity and frequency with familiarity and frequency having a rather strong positive correlation with each other. The norms and the picture database are available as supplemental materials for use in psycholinguistic studies in Turkish.     

Self‐Regulation: Relations with Theory of Mind and Social Behaviour

It is argued that self‐regulation skill is necessary both for displaying constructive behaviour and for controlling negative social behaviour, and self‐regulation might affect social behaviours by increasing the ability to understand others' minds. In this research, in order to examine different aspects of self‐regulation and their similarities and differences in terms of their relations with other constructs, we focused on both effortful control and executive function and investigated their concurrent associations with socially competent and aggressive behaviours and theory of mind (ToM). The participants were 212 preschool children in Turkey. We assessed executive functions with behavioural measures and effortful control with mother reports. We used six tasks for comprehensive assessment of mental state understanding. Children's social competency and aggressive behaviour were assessed with teacher reports. Structural equation modelling results showed that when age and receptive language were controlled, ToM was significantly associated with social competence but not aggressive behaviour. Both effortful control and executive functions were significantly related to social competency and ToM; the pathways from each self‐regulation skill were similar in strength. ToM was linked with social competence, but it did not have a mediating role in the relations of self‐regulation with social competence. The findings highlighted the importance of self‐regulation for socio‐cognitive and social development in the preschool years. Copyright © 2016 John Wiley & Sons, Ltd.     

Operationalizing the "vulnerability" and "stress" components of the hopelessness theory of depression: a multi-wave longitudinal study

The current study tested of the diathesis-stress component of the hopelessness theory (HT) using (1) a "weakest link" approach towards operationalizing vulnerability (e.g., an individual is as vulnerable to depression as his/her most depressogenic inferential style-DIS) and (2) an idiographic approach towards operationalizing high levels of stress. The procedure involved an initial assessment during which participants completed measures assessing DISs and depressive symptoms. The procedure also involved a series of eight follow-up assessments, occurring every 6 weeks, during which depressive symptoms and hassles were assessed. Hypotheses were tested in two samples of adults (i.e., adults diagnosed with a current MDE and adults diagnosed with a past MDE at Time 1). In line with hypotheses, in both samples, depressogenic weakest links were associated with greater elevations in depressive symptoms following elevations in hassles. At the same time, equally strong support was obtained for the HT when stress was operationalized from a nomothetic perspective and when vulnerability was operationalized as a DIS about causes (but not consequences or self).     

Detecting olfactory rivalry

Olfactory rivalry can occur when a binary mixture is sniffed repeatedly, with one percept dominating then the other. Experiment 1 demonstrated olfactory rivalry using several new techniques. Experiments 2 and 3 examined whether participants can notice rivalry. Participants received trials composed of odor pairs: either a mixture followed by the same mixture; or a pure odor followed by the same pure odor. On some trials participants judged whether the two stimuli were the same or different, to see if they could detect rivalry. On other trials participants judged the quality of each odor, allowing us to determine whether rivalry occurred. We found evidence for rivalry when we compared reports of odor quality for one stimulus and then the other, but no evidence that participants could detect this change. These findings are consistent with the idea that people can experience olfactory illusions, but may not know they have occurred.
