    • Negative social comparisons and psychosis proneness in a healthy adolescent population 

      Cotier, F. A.; Toulopoulou, T. (Elsevier Masson, 2017)
      There is growing evidence of an association between negative social comparisons (NSC) and both psychosis, and psychosis proneness. The majority of the work thus far, however, has focused largely on one type of NSC, namely, ...

      The world’s population is aging at an increasing rate. Even in the absence of neurodegenerative disorders, healthy aging affects perception and cognition. In the context of cognition, common factors are well established. ...
    • Not all perceptual difficulties lower memory predictions: testing the perceptual fluency hypothesis with rotated and inverted object images 

      Beşken, Miri; Solmaz, Elif Cemre; Karaca, Meltem; Atılgan, Nilsu (Springer, 2019-02)
      Studies typically show that perceptual difficulties at the time of encoding lower memory predictions. One potential exception to this is the inverted-word manipulation, in which participants produce equivalent memory ...
    • Novel object recognition is not affected by age despite age-related brain changes 

      Aktoprak, İlay; Dinç, Pelin; Günay, Gizem; Adams, Michelle M. (Scientific Research Publishing, 2013)
      Age-related memory impairments show a progressive decline across lifespan. Studies have demonstrated equivocal results in biological and behavioral outcomes of aging. Thus, in the present study we examined the novel object ...
    • A novel, low-cost Anesthesia and injection system for Zebrafish Researchers

      In this study, we designed and developed a novel low-cost system for anesthetizing and injecting adult zebrafish. The system utilizes a gradual cooling method for the anesthesia and maintains the fish in a stable anesthetic ...
    • Object rigidity and reflectivity identification based on motion analysis 

      Zang, D.; Schrater P.R.; Doerschner, Katja (IEEE, 2010)
      Rigidity and reflectivity are important properties of objects, identifying these properties is a fundamental problem for many computer vision applications like motion and tracking. In this paper, we extend our previous ...
    • The openness-calibration hypothesis 

      Lewis, D. M. G.; Al-Shawaf, L.; Yilmaz, C. (Elsevier Ltd, 2015)
      The current study tested the hypotheses that (1) psychological adaptations calibrate Openness to Experience to facilitate or deter pursuit of short-term mating, and (2) this calibration varies as a function of mating ...
    • Optimizing electrode montages of transcranial direct current stimulation for attentional bias modification in early abstinent methamphetamine users 

      Shahbabaie, A.; Hatami, J.; Farhoudian, A.; Ekhtiari, H.; Khatibi, A.; Nitsche, M. A. (Frontiers Media S.A., 2018)
      Introduction: Chronic use of most psychoactive drugs may lead to substance dependence and drug addiction. Drug addiction is a chronically relapsing disorder, and current pharmacological and behavioral therapies are not ...
    • Oscillatory synchronization model of attention to moving objects 

      Yilmaz, O. (Elsevier, 2012)
      The world is a dynamic environment hence it is important for the visual system to be able to deploy attention on moving objects and attentively track them. Psychophysical experiments indicate that processes of both attentional ...
    • Parasite stress and pathogen avoidance relate to distinct dimensions of political ideology across 30 nations 

      Tybur J.M.; Inbar Y.; Aarøe L.; Barclay P.; Barlowe F.K.; De Barra M.; Beckerh D.V.; Borovoi L.; Choi I.; Choik J.A.; Consedine N.S.; Conway A.; Conway J.R.; Conway P.; Adoric V.C.; Demirci D.E.; Fernández A.M.; Ferreirat D.C.S.; Ishii K.; Jakšic I.; Ji T.; Van Leeuwen F.; Lewis D.M.G.; Li N.P.; McIntyre J.C.; Mukherjee S.; Park J.H.; Pawlowski B.; Petersen M.B.; Pizarro D.; Prodromitis G.; Prokop P.; Rantala M.J.; Reynolds L.M.; Sandin B.; Sevi, Barış; De Smet D.; Srinivasan N.; Tewari S.; Wilson C.; Yong J.C.; Žezelj I. (National Academy of Sciences, 2016)
      People who are more avoidant of pathogens are more politically conservative, as are nations with greater parasite stress. In the current research, we test two prominent hypotheses that have been proposed as explanations ...
    • Patterns of perceived partner responsiveness and well-being in Japan and the United States 

      Tasfiliz, D.; Selcuk, E.; Gunaydin, G.; Slatcher, R. B.; Corriero, E. F.; Ong, A. D. (American Psychological Association, 2018)

    • Picture-perfect is not perfect for metamemory: testing the perceptual fluency hypothesis with degraded images 

      Besken, M. (American Psychological Association, 2016)
      The perceptual fluency hypothesis claims that items that are easy to perceive at encoding induce an illusion that they will be easier to remember, despite the finding that perception does not generally affect recall. The ...
