    Positional priming of visual pop-out search is supported by multiple spatial reference frames
    (Frontiers Media S.A., 2015) Gökçe, Ahu; Müller,H.J.; Geyer,T.
    The present study investigates the representations(s) underlying positional priming of visual ‘pop-out’ search (Maljkovic 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 – RTs– when 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. © Copyright © 2015 Gokce, Müller and Geyer.

    Emotional Word Processing Within Configural Representations
    (ISTANBUL UNIV, 2020) Memiş, Elif; Gökçe, Ahu; Güney, Çiçek; Gökçe, Ahu
    The impact of emotions on cognitive processes has been studied intensively in the last years. The aim of the present study is to investigate the relationship between visuospatial attention processes and emotions. Visuospatial attention processes were investigated by using a localization task which required processing of the words that formed the configuration. In the localization task, participants were asked to indicate the position of the target word which matched the color of the fixation cross ("+") by pressing the relevant keyboard button. In each trial, four words in different colors were positioned to form a square configuration. In different experimental conditions, words that formed the configuration varied in their valence (neutral, positive and negative words). The intertrial transitions (trial 1 -> trial 2) consisted of changes in the target's location within the configuration (e.g. top right corner), size of configuration (big/small square) and type of word (emotional/neutral). The main goal of the present study is to investigate the interaction between the processing of emotional and neutral words and certain variables. The variables were the size of the attended area and localizing the target word that was repeated or changed across trials. By changing the size of the configuration (small / big sized square) across trials, the size of the attended area was determined. The results revealed that changes in word valence and size of the configuration led to differences in the localization task performance. It was found that neutral and negative words led to target location repetition cost. Different location targets were processed faster suggesting that word processing was easier. Additionally, bigger, compared to smaller configurations, led to better performance only when emotional words were used. Overall findings of the present study suggest that configural representations are formed automatically by using the word stimuli, and they influence the processing of emotional and neutral words differently.
