This study investigates the effect of text type (humorous, positive, neutral) and relatedness (related, unrelated) and their possible interaction on memory of visual objects (chocolate bars) associated with those texts, using recognition memory and on-line eye-tracking methodologies. After studying object-text pairs during which their eye-gaze was monitored, participants performed an immediate and a delayed (2 weeks later) recognition memory task for the visual objects. Recognition memory results (hits, d') replicated the previously found “humor effect” in the literature, i.e., objects associated with humorous texts were recognized less as compared to positive and neutral texts. Relatedness had no effect. Furthermore, there was no interaction. Eye-tracking results confirmed the effect of text type in parallel with the recognition memory results, thus supporting the attention hypothesis which states that objects attended longer in the study phase are recognized better in the test phase. Contrary to recognition, eye-tracking results revealed an interaction between humor and relatedness, as hypothesized: while objects related with humorous texts were looked at longer and caused more switches between text and object, those unrelated with humorous texts were looked at shorter and caused fewer switches, a pattern that was not observed for the other text types (positive, neutral). This finding suggests that while attentional differences exist for objects associated with related vs. unrelated humorous texts, they were not reflected in recognition memory performance, possibly because the semantic relation was not explicit enough. The study also shows how behavioral performance measures (recognition memory) can be complemented by on-line measures (eye-tracking).

Hybrid statistical and machine learning modeling of cognitive neuroscience data Çakar, Serenay; Gökalp Yavuz, Fulya (2023-01-01) The nested data structure is prevalent for cognitive measure experiments due to repeatedly taken observations from different brain locations within subjects. The analysis methods used for this data type should consider the dependency structure among the repeated measurements. However, the dependency assumption is mainly ignored in the cognitive neuroscience data analysis literature. We consider both statistical, and machine learning methods extended to repeated data analysis and compare distinct algorithms ...
Eye tracking in multimodal comprehension of graphs Acartürk, Cengiz (2012-07-31) Eye tracking methodology has been a major empirical research approach for the study of online comprehension processes in reading and scene viewing. The use of eye tracking methodology for the study of diagrammatic representations, however, has been relatively limited so far. The investigation of specific types of diagrammatic representations, such as statistical graphs is even scarce. In this study, we propose eye tracking as an empirical research approach for a systematic analysis of multimodal comprehensi...
IMPULSIVE SICNNS WITH CHAOTIC POSTSYNAPTIC CURRENTS Fen, Mehmet Onur; Akhmet, Marat (2016-06-01) In the present study, we investigate the dynamics of shunting inhibitory cellular neural networks (SICNNs) with impulsive effects. We give a mathematical description of the chaos for the multidimensional dynamics of impulsive SICNNs, and prove its existence rigorously by taking advantage of the external inputs. The Li-Yorke definition of chaos is used in our theoretical discussions. In the considered model, the impacts satisfy the cell and shunting principles. This enriches the applications of SICNNs and ma...
RESPONSE BIAS SHIFT FOR POSITIVE WORDS IN OLDER ADULTS IN A SURPRISE RECOGNITION MEMORY TASK: AN INCIDENTAL ENCODING STUDY KAYNAK, HANDE; Gökçay, Didem (2017-01-01) Introduction: Although the advantages of positive words on memory enhancement have been documented, the specific effects of the two prominent emotional dimensions (valence and arousal) under incidental encoding require further investigation. The objective is to study memory accuracy and response bias for positive/negative and highly/medium arousing words in a surprise old/new recognition memory paradigm under incidental encoding.
Visual object representations: effects of feature frequency and similarity Eren Kanat, Selda; Hohenberger, Annette Edeltraud; Department of Cognitive Sciences (2011) The effects of feature frequency and similarity on object recognition have been examined through behavioral experiments, and a model of the formation of visual object representations and old/new recognition has been proposed. A number of experiments were conducted to test the hypothesis that frequency and similarity of object features affect the old/new responses to test stimuli in a later recognition task. In the first experiment, when the feature frequencies are controlled, there was a significant increas...
