Yayın Does everyone benefit equally from self-efficacy beliefs? The moderating role of perceived social support on motivation(Sage Publications Inc, 2018-02) Bağcı Hemşinlioğlu, Sabahat ÇiğdemThis study investigated whether perceived goal support from family and friends may moderate the relationship between academic self-efficacy and motivational outcomes among early adolescent students recruited from a low-middle socio-economic status(SES) background school in Turkey (N = 319, Xa(ge) = 13.13, SD = .80). Self-report questionnaires included measures of academic self-efficacy, perceived family and friend support, and academic and career motivations. Academic self-efficacy and perceived support from family related positively to both types of motivation. Children who perceived lower family support benefited more from the positive effects of self-efficacy on motivations, whereas children with higher family support seemed to gain less (or not gain at all) from self-enhancing functions of self-efficacy. Same findings were found for peer support, but only when family support was excluded from analyses. Findings implied the need to study larger family and peer contexts under which self-efficacy beliefs may be more or less effective on motivation.Yayın Towards enhancing happiness at work with the lenses of positive organizational behavior: The roles of psychological capital, social capital and organizational trust(Lumen Publishing House, 2020-06) Taştan, Seçil; Küçük, Burcu Aydın; İşiaçık, SerinIn this study, based on the approach of humanization of the postmodern organizations and depending on the conceptual background, it was suggested that psychological capital and social capital could be the significant antecedents of employee happiness at workplace. Further, it was proposed that organizational trust has a moderating role on the impact of psychological capital on happiness at workplace. Thereby, a cross-sectional research study has been performed in Turkey with the participation of 222 employees from a variety of sectors including sales, marketing, health, banking, finance and education. According to the findings, it was reported that the psychological capital construct (beta=,778; t=18,370, p<,05) and social capital (beta=,746; t=16,621, p<,05) had significant positive impacts on employees' happiness at workplace. These findings supported the proposed hypothesis 1 and hypothesis 2. In addition, it was demonstrated that organizational trust has significant positive impact on happiness at workplace (beta=,544, t=9,590, p<,05). However, the results indicated that organizational trust has no significant moderating role (p>0,05), thus hypothesis 3 was not confirmed. Further research direction and the need for research on organizational trust's moderating role are discussed. The conceptual and practical implications of the study are provided along with the concluding remarks and discussions.Yayın Alzheimer hastalığında olağan durum ağı bağlantısallığı(Türkiye Sinir Ve Ruh Sağlığı Derneği, 2019-12) Yıldırım, Elif; Soncu Büyükişcan, EzgiAmaç: Alzheimer hastalığı (AH) beyinde yapısal ve işlevsel değişimler meydana getiren nörodejeneratif bir hastalıktır. Gelişen beyin görüntüleme yöntemleri sayesinde AH patolojisine eşlik eden yapısal ve işlevsel bağlantılardaki bozulmalar gitgide daha görünür hale gelmiştir. AH’de dinlenim durumu bağlantısallığında, özellikle de olağan durum ağı (default mode network - DMN) olarak adlandırılan içsel bağlantısallık ağında farklılaşmalar görülmektedir. Bu çalışmada DMN bağlantısallık bulgularının incelenmesi ve tartışılması amaçlanmıştır. Yöntem: İşlevsel manyetik rezonans görüntüleme (fMRI) çalışmalarında en yaygın kullanılan 2 temel metodoloji (tohum temelli ve bağımsız bileşen analizi) temel alınarak alanda yapılan çalışmalar incelenmiştir. Bulgular: Çalışmalar genel olarak, DMN bağlantısallığının AH süreci boyunca ilerleyici bir şekilde bozulduğunu göstermektedir. DMN alt sistemlerinin AH’nin preklinik ve prodromal evrelerinde farklı bağlantısallık örüntüleri gösterdiği de belirtilmektedir. DMN’deki bozulmanın diğer bağlantısallık ağlarındaki farklılaşma ile ilişkili olabileceğini öne süren kanıtlar da mevcuttur. Buna ek olarak, bulgular DMN’nin AH ile ilişkili nöropatoloji ve genetik risk faktörleri ile olan ilişkisine de işaret etmektedir. Sonuç: AH’nin beyinde başta DMN olmak üzere diğer dinlenim durumu ağlarında işlevsel bozulmalara yol açan yaygın bir diskonneksiyon sendromu olduğu öne sürülebilir. Buna ek olarak, preklinik vakalarda ve risk taşıyan kişilerde de saptanabilen AH ile ilişkili işlevsel bağlantısallık değişimleri AH için muhtemel bir biyo-belirteç olabilir.Yayın Affective theory of mind in human aging: is there any relation with executive functioning?(Routledge, 2019-04) Yıldırım, Elif; Soncu Büyükişcan, Ezgi; Gürvit, İbrahim HakanTheory of Mind (ToM) refers to the ability to make inferences on other’s mental or emotional states. Although there is evidence suggesting that impaired executive functions due to aging could have a negative impact on cognitive ToM, there is still controversy about the effect of age and age-related executive dysfunctions on affective ToM. To investigate affective ToM in healthy aging and its relationship with executive functions, we examined Reading Mind in the Eyes Test (RMET) performance and executive functions among young and older adults. There was no significant difference between age groups regarding their RMET scores. While affective ToM was correlated to executive functioning within the younger group, short term memory was found to be associated with RMET performance among older participants. Furthermore, within the older group, women performed better than men. Our findings suggest a preserved ability of affective ToM in healthy aging, which appears to be independent of executive functioning.
