Source strengthening in recognition memory

Aytaç, Sinem
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 performance is not harmed by the presence of strong list items and strong items do not benefit from the accompaniment of weak items. This finding is defined as the null list-strength effect. The current thesis extended the strength-based mirror effect and the null liststrength effect to source recognition memory.


Does survival processing have an advantage over intentional learning for recognition and source recognition performance?
Oker, Kumsal İpek; Mısırlısoy, Mine; Department of Psychology (2022-8)
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 ...
Behavior Categorization Using Correlation Based Adaptive Resonance Theory
YAVAŞ, mustafa; Alpaslan, Ferda Nur (2009-06-26)
This paper presents a new method of categorizing robot behavior, which is based on a variation of Correlation Based Adaptive Resonance Theory (CobART) learning. CobART is a type of ART 2 network and its main contribution is the usage of correlation analysis methods for category matching. This study uses derivation based correspondence and Euclidian distance as correlation analysis methods for behavior categorization. Tests show that the proposed method generates better results than ART 2 categorization even...
Feature repetition effects on object familiarity: Evidence from an old/new recognition task
Eren, Selda; Hohenberger, Annette Edeltraud (2010-08-14)
We performed an old/new study/test recognition task to investigate feature repetition effects on object familiarity. The results showed that repeated features increased "old" responses during the test phase for new objects. This increase was linear with the number of repeated features on the object. Old objects, which had been among the study phase stimuli, were not affected by the number of repeated features on the object. We also analyzed the effect of feature type (colour, shape, border and pattern) on f...
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...
Face classification with support vector machine
Kepenekci, B; Akar, Gözde (2004-04-30)
A new approach to feature based frontal face recognition with Gabor wavelets and support vector machines is presented in this paper. The feature points are automatically extracted using the local characteristics of each individual face. A kernel that computes the similarity between two feature vectors, is used to map the face features to a space with higher dimension. To find the identity of a test face, the possible labels of each feature vector of that face is found with support vector machines, then the ...
