Publication Metadata only Discrete memories of a continuous world: a working memory perspective on event segmentation(Elsevier B.V., 2024) Güler, Berna; Uysal, Bilge; Günseli, Eren; Adıgüzel, Zeynep; Graduate School of Social Sciences and HumanitiesWe perceive the world in a continuum but remember our past as discrete episodic events. Dominant models of event segmentation suggest that prediction errors or contextual changes are the driving factors that parse continuous experiences into segmented events. These models propose working memory to hold a critical role in event segmentation, yet the particular functioning of working memory that underlies segmented episodic memories remains unclear. Here, we first review the literature regarding the factors that result in the segmentation of episodic memories. Next, we discuss the role of working memory under two possible models regarding how it represents information within each event and suggest experimental predictions. Clarifying the contributions of working memory to event segmentation is important to improve our understanding of the structure of episodic memories.Publication Metadata only Vertical individualism orientations and mental health stigma: the mediating role of belief in free will(Springer, 2023) Ozkok, Hazal; Altan-Atalay, Ayse; Department of Psychology; Turan, Bülent; Özkök, Maide Hazal; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and HumanitiesEven though the stigma related to mental health is widespread, stigma related to suicide and substance use are less researched areas. This study investigates whether belief in free will mediates the association between vertical individualism and stigma against those who use substances or attempt suicide. Turkish adult participants (n = 200, M-age = 29.8, SD = 11.9) completed self-report measures of cultural orientation, belief in free will, substance use stigma, and suicide stigma. Results revealed that individuals' belief in free will mediates the association of vertical individualism with both suicide and substance use stigma. This suggests that free will belief may be one of the ways in which cultural orientations are linked to stigma. These results can contribute to the design of sophisticated stigma reduction interventions that take into account belief in free will and cultural orientation.Publication Metadata only Understanding patterns of accumulation: improving forecast-based decisions via nudging(Springer, 2024) Boz-Yilmaz, Hatice Zulal; Department of Psychology; Gököz, Zeynep Ayşecan Boduroğlu; Department of Psychology; College of Social Sciences and HumanitiesIn this study we investigated challenges associated with comprehension of graphical patterns of accumulation (Experiment 1) and how to improve accumulation-based reasoning via nudging (Experiment 2). On each trial participants were presented with two separate graphs, each depicting a linear, saturating, or exponential data trajectory. They were then asked to make a binary decision based on their forecasts of how these trends would evolve. Correct responses were associated with a focus on the rate of increase in graphs; incorrect responses were driven by prior knowledge and beliefs regarding the context and/or selective attention towards the early phases of the line trajectories. To encourage participants to think more critically and accurately about the presented data, in Experiment 2, participants completed a nudge phase: they either made a forecast about a near horizon or read particular values on the studied trajectories prior to making their decisions. Forecasting about how the studied trajectories would progress led to improvements in determining expected accumulation growth. Merely reading values on the existing trajectory did not lead to improvements in decision accuracy. We demonstrate that actively asking participants to make specific forecasts prior to making decisions based on the accumulation trajectories improves decision accuracy.Publication Metadata only Temporal integration of target features across and within trials in the attentional blink(Springer, 2024) Semizer, Yelda; Department of Psychology; Yıldırım, Bugay; Gököz, Zeynep Ayşecan Boduroğlu; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and HumanitiesAttentional blink research has typically investigated attentional limitations in multiple target processing. The current study investigated the temporal integration of target features in the attentional blink. Across two experiments, we demonstrated that the orientation estimations of individual target items in the attentional blink paradigm were systematically biased. Specifically, there was evidence for both within- and across-trial biases, revealing a general bias towards previously presented stimuli. Moreover, both biases were found to be more salient for targets suffering from the attentional blink. The current study is the first to demonstrate an across-trial bias in responses in the attentional blink paradigm. This set of findings is in line with the literature, suggesting that the human visual system can implicitly summarize information presented over time, which may lead to biases. By investigating temporal integration in the attentional blink, we have been able to address the modulatory role of attention on biases imposed by the implicit temporal effects in estimation tasks. Our findings may inform future research on attentional blink, serial dependence, and ensemble perception.Publication Metadata only Characteristics and functions of predictive and directive memories and forecasts(Wiley, 2024) Department of Psychology; Ay, Demet; Gülgöz, Sami; Department of Psychology; College of Social Sciences and HumanitiesEarlier research focused on three functions of recollecting the past self, social, and directive functions, but few studies examined the characteristics of events serving these functions. Moreover, research has neglected the function of prediction, which refers to predicting the future by recollecting the past. The current study distinguished the predictive function from the directive function and aimed to characterize memories and future events serving different functions by employing function prompts as cues. In addition, the frequency of using function-cued memories for the other functions was measured. Results showed that predictive and directive function ratings of the predictive function cued events were significantly different. However, directive events served the predictive function as frequently as the directive function, indicating that the predictive function is a prerequisite for future planning conceptualized under the directive function. The results are indicative of a distinct predictive function and considerable overlap between functions of memories.Publication Metadata only Autobiographical remembering regulates emotions: a functional perspective(Routledge Journals, Taylor & Francis Ltd, 2018) N/A; N/A; Department of Psychology; Öner, Sezin; Gülgöz, Sami; PhD Student; Faculty Member; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; 181122; 49200Emotional deviation has been considered an essential factor in emotion regulation, in that, attempts to compensate for the deviation is reflected on cognitive processes. In the present study, we focused on autobiographical remembering and tested the functional role of memory on emotion regulation. We specifically examined the congruence effect in individuals' subsequent memory reports after recalling emotional events. Individuals were randomly assigned to three groups to report either sadness or anger evoking events or emotionally unspecified events that they experienced in the last five years. Results supported mood-incongruence, but only for the emotional memory groups. Despite highly negative memories reported in the initial recall, individuals in anger- and sad-memory groups revealed an up-regulation trend in subsequent recall. Furthermore, sadness and anger induction affected phenomenological features of the subsequently reported memory. Overall, our findings supported for the emotion regulation function of remembering that serves counter-regulation of the negative emotion. We discuss potential mechanisms in the light of explanations by a functional approach to autobiographical memory.Publication Metadata only The roles of stimulating parenting and verbal development throughout early childhood in the development of mathematics skills(Elsevier Science Inc, 2021) N/A; N/A; Department of Psychology; Özkan, Deniz; Baydar, Nazlı; PhD Student; Faculty Member; Department of Psychology; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; 366989; 50769This study investigated the unique contributions of mothers' stimulating parenting practices and children's verbal skills throughout early childhood to the prediction of their mathematics skills at age 7, using data from a 5-year longitudinal study of a nationally representative cohort of 3-year-old children in Turkey (N = 1,052, 55.4 % male). Structural models were estimated and systematically tested in order to arrive at a parsimonious model including children's initial verbal and mathematics skills, and stimulating parenting behaviors throughout early childhood. Broadly defined stimulating parenting at ages 3, 4, and 5 had substantial continuity, nevertheless uniquely and significantly predicted the mathematics skills at age 7. The predictive associations of stimulating parenting with children's mathematics skills at age 7 were mediated by the children's verbal skills at age 6. The contributions of specific stimulating parenting behaviors and specific verbal skills to early elementary mathematics skills were discussed.Publication Metadata only Sequential temporal discrimination in humans and mice(The Regents of the University of California, 2015) Department of Psychology; N/A; Department of Psychology; N/A; Balcı, Fuat; Berkay, Dilara; Sayalı, Zeynep Ceyda; Çoşkun, Filiz; Faculty Member; Master Student; Undergraduate Student; Master Student; Department of Psychology; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; College of Social Sciences and Humanities; Graduate School of Social Sciences and Humanities; 51269; N/A; N/A; N/APrevious studies showed that humans and mice can maximize their rewards in two alternative temporal discrimination tasks by incorporating exogenous probabilities and endogenous timing uncertainty into their decisions. The current study investigated whether the probabilistic relations modulated the temporal discrimination performance in scenarios with more than two temporal options. In order to address this question, we tested humans (Experiment 1) and mice (Experiment 2) in the dual-switch task, which required subjects to discriminate three time intervals (short, medium, and long durations) in a sequential fashion. The latencies of switches from short to medium and from medium to long option were the main units of analysis. The results revealed that the timing of switches between the first two options (short-to-medium) were sensitive to probabilistic information in both humans and mice. Mice but not humans adapted the timing of their subsequent switches between the last two options (medium-to-long) based on the probabilistic information associated with these latter options. These results point at a suboptimal tendency in the temporal decisions of humans with multiple options.Publication Metadata only Effect of maternal education on Turkish mother' styles of reminiscing with their children(Türk Psikologlar Derneği, 2004) Department of Psychology; Department of Psychology; Küntay, Aylin C.; Ahtam, Banu; Faculty Member; Undergraduate Student; Department of Psychology; College of Social Sciences and Humanities; College of Social Sciences and Humanities; 178879; N/AThis study investigates the relationship of maternal education to the style of mother-child conversations about past events. Previous research conducted in the US has identified two distinct styles of communication that mothers use to elicit talk about past events from their children (i.e., elaborative style and repetitive style), but the relationship of these patterns of talk to mothers’ education level has not been investigated. In this study, we recorded 22 mother-child pairs. of these, half included mothers of high educational background, and the other half had mothers of low educational background. Mothers’ child-directed utterances were coded in terms of their forms, contents, and relationships to the child’s responses. Results show that high-education mothers addressed more utterances per event to their children than low-education mothers. Also, child-directed speech of high-education mothers tended to be more elaborative and less repetitive than the speech of low-education mothers. One major contributor to this overall difference was that high-education mothers offered more elaborative statements than low-education mothers. The proportions of questioning behavior, on the other hand, were the same across the two groups of mothers. The pattern of differences found in the study could be explained by the longer exposure of high-education mothers to "classroom discourse" in addition to the potential facilitative effects of schooling on their communicative and narrative skills. / Öz: Bu çalışma, annelerin çocuklarıyla geçmişteki olaylar hakkında konuşma davranışlarıyla anne eğitim düzeyinin ilişkisini araştırmaktad›r. ABD’de yapılan araştırmalar, annelerin çocuklarıyla anıları hakkında konuşurken kullandığı ayrıntıcı (elaborative) ve tekrarcı (repetitive) olmak üzere iki ayrı konuşma biçimi belirlemiş, fakat bu stillerin annelerin eğitim düzeyleriyle ilişkisini incelememiştir. 11 yüksek ve 11 düşük eğitim düzeyli annenin, çocuklarına geçmiş olayları hatırlatmaya çalışırken geçen konuşmaları teybe kaydedilmiştir. Annelerin çocuklarına yönelik sözceleri (utterance), biçim, içerik ve çocuktan gelen yanıtla ilişkili olarak kodlanmıştır. Bulgularda, her iki gruptaki anneler de aynı sayıda olaydan bahsederken, yüksek eğitimli annelerin olay başına daha fazla sayıda sözce oluşturduğu görülmüştür. Ayrıca eğitim düzeyi yüksek annelerin, eğitim düzeyi düşük annelerle karşılaştırılınca, daha fazla ayrıntıcı ve daha az tekrarcı bir konuşma stili kullanma eğilimi gösterdikleri bulunmuştur. Bu farkın en önemli kaynağı kullanılan farklı soru oranları ve biçimleri değil, yüksek eğitimli anneler tarafından daha sıklıkla kullanılan olayların detaylarını betimleyen bildirim cümleleridir. Bulunan farklılıkların nedenleri olarak, annelerin eğitimlerinin uzunluğuyla ilişkili olarak geliştirdikleri "okul söylemiyle" tanıklıkkları ve bunun sonucunda edindikleri ayrıntıcı anlatı ve iletişim becerileri düşünülebilinir.Publication Metadata only Gaze-based prediction of pen-based virtual interaction tasks(Academic Press Ltd- Elsevier Science Ltd, 2015) Department of Computer Engineering; Department of Computer Engineering; Çiğ, Çağla; Sezgin, Tevfik Metin; PhD Student; Faculty Member; Department of Computer Engineering; College of Engineering; College of Engineering; N/A; 18632In typical human-computer interaction, users convey their intentions through traditional input devices (e.g. keyboards, mice, joysticks) coupled with standard graphical user interface elements. Recently, pen-based interaction has emerged as a more intuitive alternative to these traditional means. However, existing pen-based systems are limited by the fact that they rely heavily on auxiliary mode switching mechanisms during interaction (e.g. hard or soft modifier keys, buttons, menus). In this paper, we describe how eye gaze movements that naturally occur during pen-based interaction can be used to reduce dependency on explicit mode selection mechanisms in pen-based systems. In particular, we show that a range of virtual manipulation commands, that would otherwise require auxiliary mode switching elements, can be issued with an 88% success rate with the aid of users' natural eye gaze behavior during pen-only interaction.
