Article Peter Shaffer’s Equus and Equine-Assisted Psychotherapy (eap)(2022-12-21) Bal, MustafaPeter Shaffer’s Equus (1973) is a distinctive play in its representation of complex psychological/psychiatric issues on the theatre stage. As such, the play is one of the most notable theatrical works of psychological realism in English theatre. Peter Shaffer achieves this especially through his characterization of the mentally unstable Alan Strang. Since his childhood, Alan has developed an extraordinary attachment to and obsession with horses, and this eventually results in his blinding six horses and his entrustment to the treatment of the psychiatrist Martin Dysart. Accordingly, Equus has been, so far, studied through various – mainly psychological and psychiatric – perspectives. In this sense, the aim of this article is to shed a new light and contribute to these studies by examining the close relations between Peter Shaffer’s Equus and equine-assisted psychotherapy (EAP) – an acknowledged method of psychiatric treatment by means of horses that psychiatrist Dysart of the play neglects (or is unaware of ) while planning his therapies for Alan, who, due to his intimacy with horses, also as a stable-boy, might benefit from the methods of equine-assisted psychotherapy. For this purpose, this article analyses and reveals the ties between the play and equine-assisted psychotherapy mainly through related studies on the therapy, Shaffer’s characterization of Alan, and relevant incidents in the play.Article When Are You Going To Marry? Intention To Marry Through the Lens of Theory of Planned Behavior and Self-Regulatory Focus(Turkish Psychological Counseling and Guidance Association, 2024-03-29) Koçak, Aylin; Mouratidis, A.What makes people to take important decisions in their lives, such as marriage? To answer this question, we relied on theory of planned behavior to examine the degree to which peoples' attitudes, subjective-norms, and behavioral control perceptions predict their intentions to marry. Furthermore, we used self-regulatory focus theory to examine whether such attitudes, norms, and perceptions could be partly explained by peoples' focus on pursuing-gains versus securing non-losses. We conducted a cross-sectional, web-based survey with a sample of 699 Turkish young adults (70.7% females; Mage =24.89 years, SD = 4.31). The results of the structural equation modeling showed that promotion-focus positively and prevention-focus negatively related to perceived behavioral control, which in turn negatively related to intentions to marry. Intentions also related positively to attitudes but not to subjective-norms, which however related positively to promotion-focus and negatively to prevention-focus. Gender and age differences were also found. The results are discussed in light of the two theories. © 2024 The Authors.

Materials and Methods: Twenty-two patients with PD-MCI, 23 with PD-CN, and 23 healthy controls with structural brain magnetic resonance imaging scans and complete neuropsychological tests were enrolled in this study. Cortical thickness analysis was performed using the Statistical Parametric Mapping 12 software package. Correlations with cognitive functions were examined. Results: Cortical thickness was significantly lower in the PD-CN and PD-MCI patient groups than in healthy controls in the left precuneus and isthmus-cingulate cortex, right pars orbitalis, insula, and lateral orbitofrontal cortex. In addition, the PD-MCI group also exhibited cortical thinning in the left superior temporal gyrus, transverse temporal cortex, supramarginal gyrus, and bilateral posterior cingulate cortex compared with healthy controls. Correlation analyses among cortical thickness and cognitive scores of PD also revealed moderate associations between memory and the posterior cingulate cortex; language and the precuneus; and executive functions and the insula and isthmus-posterior cingulate cortices. Conclusion: MCI in PD may be related to cortical alterations in the posterior cingulate cortex and the left temporoparietal cortex, which has been associated with subtle cognitive deficits in PD.Article Citation - WoS: 3Citation - Scopus: 5Psychological Maltreatment of Women Inventory Short Form - Turkish Adaptation(Klinik Psikiyatri Dergisi, 2017) Ersoy, Nevra Cem; Hunler, Olga Selin; Namer, YuditObjective: This study aims to adapt a short form of Psychological Maltreatment of Women Inventory (Tolman 1989) to Turkish and to examine the psychometric properties of the Turkish short form. Method: Participants were 852 women between the ages of 2355 (32.12 +/- 10.97 years), who were either married (48%) or in a romantic relationship (47%) during data collection. The questionnaire was comprised of Psychological Maltreatment of Women Inventory (PMWI), Submissive Acts Scale (SAS) and demographic information form. Principal Components Analysis was used for confirmatory construct validity, and Pearson correlation coefficients between SAS and PMWI total scores were calculated for discriminatory validity. Cronbach-Alpha internal consistency coefficients and split-half reliability were measured to establish internal consistency. Results: The three-factor (Restriction/Blaming/Threat; Emotional-Verbal Violence; Responsibility) structure explained 64.3% of variance. Internal consistency coefficient (Cronbach-Alpha) was found to be .93; split half reliability was found to be .90 and .87 for the first and second halves, respectively, and the correlation between the two halves were found to be .71. Conclusion: The Turkish short form of Psychological Maltreatment of Women Inventory is a valid and reliable tool to measure psychological maltreatment experienced by married women, or women in romantic relationships.Article Citation - WoS: 1Increased Serum Levels of Nmda Receptor Antibodies in Female Patients With Bipolar Disorder(Klinik Psikiyatri Dergisi, 2018) Ceylan, Deniz; Akan, Pinar; Doyuran, Kerim; Can, Gunes; Ersen, Ayca; Misir, Emre; Ozerdem, Aysegul; Acar, Can M. Güneş; Özalp, Deniz Ceylan TufanObjective: Glutamatergic/GABAergic imbalance due to autoimmune antibodies targeting N-methyl-D-aspartate receptors (NMDA-R) is considered to be one of the shared pathways between bipolar disorder (BD) and autoimmune diseases. Evidence shows female vulnerability to autoimmune disorders, and suggests a sex-specific approach in autoimmunity research in BD. We aimed to assess serum concentrations of NMDA-R antibodies and density of NMDA and GABA receptors on platelets in euthymic patients with BD in comparison to healthy individuals; and to determine the impact of sex on serum concentrations of NMDA-R antibodies and the density of NMDA and GABA receptors on platelets. Method: NMDA antibody IgG were detected in serum samples of 27 DSM IV euthymic patients with bipolar disorder (16 females, 11 males) and 33 healthy individuals (17 females, 16 males), using ELISA method. The densities of NMDA and GABA receptors on platelets were investigated using immunocytochemical methods. Results: Patients with BD presented higher serum levels of NMDA-R antibodies in comparison to healthy individuals (p < 0.001). The densities of NMDA and GABA receptor on platelets were similar in both groups. The NMDA-R antibody levels were influenced by both diagnosis and sex (F = 5.813, df = 1, p = 0.020). Tserum lithium levels showed a significant linear association with the serum NMDA-R antibody levels even adjusting for age, sex, body mass index (F = -56.26, t = -2.52, p = 0.015, CI: -101.12/-11.40). Discussion: Our findings support a potential role of NMDA-R antibodies in the underlying pathophysiology of BD, particularly for females.Article Citation - Scopus: 2Behavioral Immune System and Trypophobia(Klinik Psikiyatri Dergisi, 2022) Ozturk, Suleyman; Ceylan, Deniz; Demir, Ayse Banu; Kazdagli, Hasan; Erdeniz, BurakPathogens, which are the source of infectious diseases, have imposed a strong selection pressure on human evo-lution as one of the most important causes of human death during the natural selection process. As a result of this, it is assumed that a variety of adaptations have evolved against infection threats and one of these adap-tations is the physiological immune system. However, activation of the physiological immune system can be quite costly for organisms in some cases, and therefore it has been recently proposed in evolutionary psychology that an adaptive system called behavioral immune sys-tem may have evolved in association with the proactive functional processes against pathogen threats. Furthermore, it was hypothesized that a number of psy-chopathologies might develop as a result of maladaptive processes affecting the functionality of this system, and one of these psychopathologies might be trypophobia. Trypophobia refers to a psychological disorder in which individuals experience aversion and disgust at excessive levels toward clusters of small objects such as holes and bumps. Following this, the current review was estab-lished within the framework of three distinct goals. Firstly, this review aimed to discuss the evolutionary basis and mechanisms of the behavioral immune system. Secondly, the review aimed to discuss the characteristic features and the etiological explanations of trypophobia. Finally, the review aimed to discuss how potential changes in the behavioral immune system might lead to the development of trypophobia.Article Turkish Adaptation and Validation of Behavioral Inhibition Questionnaire Parent Form(Aves, 2023-01-02) Kilinc, Saliha; Bilgiç, Ayhan; Gormez, VahdetBackground: Behavioral inhibition has been proposed as a temperamental risk factor for the development of childhood anxiety disorders universally; however, there is no validated instrument for, especially, its evaluation in Turkish children. This study aimed to examine reliability and validity of the Turkish version of Behavioral Inhibition Questionnaire parent form for children aged 3-7 years. Methods: Around 250 mothers or fathers of 3-7 years old children were recruited from non-clinical population to collect responses to the questionnaires. The sample was created by reaching 3 schools at preschool or elementary grade for the purpose of providing the questionnaires filled about the student and/or his/her little sisters and brothers by their parents; questionnaires were sent out to parents and then gathered. Parents were asked to fill sociodemographic data form, Behavioral Inhibition Questionnaire parent form, Children Behavior Questionnaire, and Strengths and Difficulties Questionaire parent form in order to perform convergent and divergent validity analyses. Results: As a result of reliability analysis, total Cronbach alpha coefficient for Behavioral Inhibition Questionnaire was determined as 0.92 with strong reliability. The internal consistency coefficients for Behavioral Inhibition Questionnaire subscales also showed strong reliability with alphas ranging between 0.81 and 0.87 except for the performance (a = 0.69) and physical challenges (a = 0.19) subscales of which some items were excluded due to item-total correlations and confirmatory factor analysis results. In the validity assessment analyses, confirmatory factor analysis demonstrated that Behavioral Inhibition Questionnaire has a construct validity with 5 factors loaded on the 2-second order main factors and one third-order final factor (root mean square error = 0.032, root mean square residual = 0.153, Comparative Fit Index = 0.978, Goodness of Fit Index = 0.915, and Turker-Lewis Index = 0.970). While the strongest correlations with the overall Behavioral Inhibition Questionnaire score were found for 2 main subscales, inhibition to social novelties (r = 0.926, P <.001) and situational novelties (r = 0.928, P <.001), similarly peers (r = 0.848, P <.001) and new situations (r = 0.898, P <.001) subscales, had strong correlations with the overall Behavioral Inhibition Questionnaire score. The weakest correlation with overall Behavioral Inhibition Questionnaire score was observed for physical challenges subscale even though this subscale displayed moderate association (r = 0.454, P <.001). A good convergent validity was determined accompanied by significant moderate positive correlations with Children Behavior Questionnaire shyness and Strengths and Difficulties Questionnaire internalizing scales. An adequate divergent validity was also demonstrated based on significant positive mild to moderate correlations with Children Behavior Questionnaire impulsivity, Children Behavior Questionnaire smiling/laugh, Strengths and Difficulties Questionnaire prosocial scales, and nonsignificant correlation with Strengths and Difficulties Questionnaire externalizing scale. Conclusion: The study demonstrated that the Turkish version of the Behavioral Inhibition Questionnaire parent form is an effective tool with good reliability and validity among 3-7 years old children.Review Article Citation - WoS: 2Citation - Scopus: 4Innovations in Neurophysiology and Their Use in Neuropsychiatry(Turkish Neuropsychiatry Assoc-Turk Noropsikiyatri Dernegi, 2022) Yener, Görsev; Öz, DidemMany structural and functional tests are used to explore the nature of neurodevelopmental and neurodegenerative diseases. Cognitive involvement has become more and more remarkable in many neurological and psychiatric disorders. This condition evoked a paradigm shift, and today disorders are addressed from a neuroscientific perspective, including silent symptoms. The spatial resolution of structural studies is lacking and is combined with the unique temporal resolution of EEG methods. In our current clinical practice, EEG does not have definitive diagnostic value in psychiatric disorders, but it helps to make a correct diagnosis by excluding other neurological diseases. However, the use of EEG for research purposes is promising in both groups. In this review; there is up-to-date information on the use of electrophysiological examinations in neurological diseases, especially Alzheimer's disease, Parkinson's disease, Frontotemporal dementia, and psychiatric disorders such as schizophrenia, mood disorders, attention deficit and hyperactivity disorder, and obsessive-compulsive disorder, to define the point we have reached in our journey to understand these disorders.Article Citation - WoS: 2Citation - Scopus: 1Towards Automaticity in Reinforcement Learning: a Model-Based Functional Magnetic Resonance Imaging Study(Turkish Neuropsychiatry Assoc-Turk Noropsikiyatri Dernegi, 2019) Erdeniz, Burak; Done, JohnIntroduction: Previous studies showed that over the course of learning many neurons in the medial prefrontal cortex adapt their firing rate towards the options with highest predicted value reward but it was showed that during later learning trials the brain switches to a more automatic processing mode governed by the basal ganglia. Based on this evidence, we hypothesized that during the early learning trials the predicted values of chosen options will be coded by a goal directed system in the medial frontal cortex but during the late trials the predicted values will be coded by the habitual learning system in the dorsal striatum. Methods: In this study, using a 3 Tesla functional magnetic resonance imaging scanner (fMRI), blood oxygen level dependent signal (BOLD) data was collected whilst participants (N=12) performed a reinforcement learning task. The task consisted of instrumental conditioning trials wherein each trial a participant choose one of the two available options in order to win or avoid losing money. In addition to that, depending on the experimental condition, participants received either monetary reward (gain money), monetary penalty (lose money) or neural outcome. Results: Using model-based analysis for functional magnetic resonance imaging (fMRI) event related designs; region of interest (ROI) analysis was performed to nucleus accumbens, medial frontal cortex, caudate nucleus, putamen and globus pallidus internal and external segments. In order to compare the difference in brain activity for early (goal directed) versus late learning (habitual, automatic) trials, separate ROI analyses were performed for each anatomical sub-region. For the reward condition, we found significant activity in the medial frontal cortex (p<0.05) only for early learning trials but activity is shifted to bilateral putamen (p<0.05) during later trials. However, for the loss condition no significant activity was found for early trials except globus pallidus internal segment showed a significant activity (p<0.05) for later trials. Conclusion: We found that during reinforcement learning activation in the brain shifted from the medial frontal regions to dorsal regions of the striatum. These findings suggest that there are two separable (early goal directed and late habitual) learning systems in the brain.
