    Attachment Anxiety Benefits From Security Priming: Evidence From Working Memory Performance
    (Public Library Science, 2018) Gökçe, Ahu; Harma, Mehmet
    The present study investigates the relationship between the attachment dimensions (anxious vs. avoidance) and the cognitive performance of individuals specifically whether the attachment dimensions would predict the working memory (WM) performance. In the n-back task reflecting the WM capacity both attachment related and non-attachment related words were used. Participants were randomly assigned into two groups that received either the secure or the neutral subliminal priming. In the secure priming condition the aim was to induce sense of security by presenting secure attachment words prior to the n-back task performance. In neutral priming condition neutral words that did not elicit sense of security were presented. Structural equation modeling revealed divergent patterns for attachment anxiety and avoidance dimensions under the different priming conditions. In neutral priming condition WM performance declined in terms of capacity in the n-back task for individuals who rated higher levels of attachment anxiety. However in the secure priming condition WM performance was boosted in the n-back task for individuals who rated higher levels of attachment anxiety. In other words the subliminal priming of the security led to increased WM capacity of individuals who rated higher levels of attachment anxiety. This effect however was not observed for higher levels of attachment avoidance. Results are discussed along the lines of hyperactivation and deactivation strategies of the attachment system.

    Positional Priming of Visual Pop-Out Search Is Supported by Multiple Spatial Reference Frames
    (Frontiers Media, 2015) Gökçe, Ahu; Mueller, Hermann J.; Geyer, Thomas
    The present study investigates the representations(s) underlying positional priming of visual pop-out' search (Maljkodc and Nakayama 1996). Three search items (one target and two distractors) were presented at different locations in invariant (Experiment 1) or random (Experiment 2) cross-trial sequences. By these manipulations it was possible to disentangle retinotopic spatiotopic and object-centered priming representations. Two forms of priming were tested: target location facilitation (i.e. faster reaction times - RTswhen the trial n target is presented at a trial n-1 target relative to n-1 blank location) and distractor location inhibition (i.e. slower RTs for n targets presented at n-1 distractor compared to n-1 blank locations). It was found that target locations were coded in positional short-term memory with reference to both spatiotopic and object-centered representations (Experiment 1 vs. 2). In contrast distractor locations were maintained in an object-centered reference frame (Experiments 1 and 2). We put forward the idea that the uncertainty induced by the experiment manipulation (predictable versus random cross-trial item displacements) modulates the transition from object- to space-based representations in cross-trial memory for target positions.

    Psikoloji ve Açık Bilim
    (İstanbul Bilgi Üniversitesi, 2022) Gökçe, Ahu; Akirmak, Umit; Cem Tüzün
    Bu kitap yaklaşık son on yıldır var olan, üzerinde daha fazla düşünülerek evirilmiş ve gelişen teknolojinin desteğini de alarak daha önce var olmayan birçok imkân sunan açık bilim pratikleri üzerine yazılmıştır. Açık bilim ve pratikleri birçok araştırmacı tarafından bilinmemektedir ve tecrübeli araştırmacılara dahi yabancı bir kavram olabilmektedir. Açık bilim prensiplerini teorik olarak bilen ama nasıl uygulanacağı konusunda tereddütte olan araştırmacılar da vardır ki çok kısa bir geçmişi olan bir kavram olduğu düşünüldüğünde bu pek şaşırtıcı değildir. Bu kitabı yazma amacımız açık bilim prensip ve uygulamalarını hem teorik hem de pratik olarak tanıtmak ve bu sayede araştırmacıların kendi bilimsel araştırmalarında bu pratiklerden faydalanmasını sağlamaktır. Bu kitap yüksek lisans ve üzeri eğitim almış tüm araştırmacıların faydalanabileceği bir kaynaktır.
