It has been widely shown that processing words according to their relevance to a survival scenario leads to a better memory performance for recall and recognition compared to a moving scenario. From an adaptive perspective, the survival processing advantage (the SPA) has been explained, referring to the notion that human memory is selectively tuned for fitness-relevant information. Alternatively, the possible richer and distinctive encoding that the survival scenario provides was suggested as an underlying mechanism. Recently, the SPA was replicated to source memory when the survival scenario was the source itself. In the current study, we aimed to investigate the interaction between intention to learn and survival processing on item and source recognition performance. To do this, an experiment with 2(context: survival vs. moving) x 3(learning: true-incidental, source-incidental, intentional) mixed design was conducted. It was hypothesized that the SPA would be observed for both item and source recognition regardless of the learning manipulations. However, the performance of the words rated with the moving scenario was expected to vary across learning conditions. In other words, the level of the SPA was expected to change with the intention to learn. As expected, we replicated the SPA on item and source recognition. Nevertheless, contrary to our second expectation, we did not observe any effect of learning instructions on both contexts. These results were discussed with possible underlying ultimate and proximate mechanisms of survival processing, and functional differences in the episodic long-term memory.

THE EFFECT OF CRITERION SHIFTS ON FAMILIARITY AND RECOLLECTION IN RECOGNITION MEMORY Erbaş, Zeynep; Kılıç Özhan, Aslı; Department of Psychology (2022-3-17) Familiarity and recollection refer to memory processes that are engaged during recognition judgments. A task that is widely used to operationalize these processes is the remember-know task. In this thesis, it was aimed to examine the effect of different decision criteria on the corresponding “remember” and “know” responses with respect to the signal detection model of recognition memory. In line with this purpose, a standard recognition memory task was applied with a between-subjects criterion manipulation....
The Effects of source presentation and test format on recognition memory for item and source Tanyaş, Hilal; Mısırlısoy, Mine; Department of Psychology (2019) Source monitoring is a cognitive process through which memory records are attributed to their origins. In the literature, source monitoring tasks are used to examine the old/new recognition decisions, as well as decisions for source. However, there is not an agreed on standard for test formats and the way in which source information is presented. In fact, these different methods are used interchangeably despite words of caution from several researchers regarding the confounds they may give rise to when maki...
Source strengthening in recognition memory Aytaç, Sinem; Kılıç Özhan, Aslı; Department of Psychology (2019) This thesis aimed to explore the list-strength paradigm in source recognition memory. Items can be strengthened through repetition, slower representation or deeper encoding either in different lists (pure-list) or within the same list (mixedlist). The strength-based mirror effect is the finding that when items are strengthened in a pure list, hit rates increase and false alarm rates decrease compared to the weakly encoded items. When a mixed-strength list is implemented, weak items’ recognition memory perfo...
Tanıma Belleğinde Kriter Belirleme ve Tepki Yanlılığı Değişimlemeleri Pala, Cavit Deniz; Kılıç Özhan, Aslı (2020-06-01) Tanıma belleği, geçmişte deneyimlenen uyaranları diğerlerinden ayırt etme becerisidir. Tipik bir tanıma belleği görevinde bir dizi uyaranın katılımcıya sunulduğu çalışma aşamasının ardından test aşamasında sorulan maddelerin çalışma listesinde bulunup bulunmadığının ayırt edilmesi beklenir. Sinyal belirleme kuramına (Macmillan ve Creelman, 2005) göre test maddeleri bellek izleriyle kıyaslanarak bir bellek gücü değeri elde edilir. Bu bellek gücü değeri öznel karar kriterini aşıyorsa madde tanınır. Test pefor...
The Relationship between Source Memory and Linguistic Encoding of Source: A Study of 3-6 year-olds Ogel-Balaban, Hale; Aksu-Koc, Ayhan; Alp, I. Ercan (2012-12-01) This study aimed to explore whether the development of source memory is related to the use of linguistic markers of evidentiality. Eighty-seven 3-, 4-, 5-, and 6-year-old Turkish-speaking monolingual children participated in two source memory tasks: (1) Mode of Knowledge Acquisition Task and (2) Source Identification Task, and three language tasks (1) Direct Experience Task, (2) Inference Task and (3) Reportative Task. Results of the source memory tasks revealed lower performance for 3-year-old children com...
