The item-specific proportion congruency (ISPC) effect is demonstrated by a smaller Stroop effect observed for mostly incongruent items compared to mostly congruent items. Currently, there is a continuing debate on whether conflict driven item-specific control processes or stimulus-response contingency learning account for the ISPC effect. In the present study, we conducted two experiments to investigate the time course of the ISPC effect with a stimulus onset asynchrony (SOA) manipulation. Both negative and positive SOAs were used in order to manipulate the contingency learning between the word and the color dimensions. We also combined this SOA manipulation with a set size manipulation (Bugg and Hutchison, 2013) to moderate the contribution of contingency learning and item-specific processes to the observed ISPC effect. We expected that the change in the magnitude of the ISPC effect as a result of SOA would follow different patterns for the 2-item and 4-item set conditions. Results showed that the SOA manipulation influenced the ISPC effect. Specifically, when the word followed the color with a 200 ms delay, the observed ISPC effect was smaller, if at all present, than the ISPC effects in other negative and positive SOA conditions, regardless of set size. In conclusion, our results showed that the ISPC effect was not observed if the word arrived too late. We also conducted additional awareness and RT distribution analyses (delta plots) to further investigate the ISPC effect. These analyses showed that a higher percentage of participants were aware of the ISPC manipulation in the 2-item set condition compared to the 4-item set condition. Delta plots revealed that the ISPC effect was smaller for fastest responses and increased as the responses got slower.

The item-specific proportion congruency effect is observed with a color-word verification task: ımplications for ıtem-specific control and stimulus-response contingency learning explanations Mısırlısoy, Mine (null; 2017-11-12) The item-specific proportion congruency (ISPC) effect is demonstrated by a smaller Stroop effect for mostly incongruent (MI) items compared to mostly congruent (MC) items. Currently, there is an ongoing debate regarding the contribution of automatic control processes and stimulus-response contingency learning processes to the ISPC effect. The aim of the present study was to further explore the cognitive processes underlying the ISPC effect. Specifically, the ISPC effect was investigated by using a color-wo...
The effects of stimulus onset asynchrony on the item-specific proportion congruency effect in a picture-word stroop task Mısırlısoy, Mine; Bozkurt, Özge; Tanyaş, Hilal (null; 2019-09-28) The item-specific proportion congruency (ISPC) effect is demonstrated by a larger Stroop effect for mostly congruent (MC) items compared to mostly incongruent (MI) items. In previous studies, we showed that the ISPC effect changed as a function of stimulus onset asynchrony (SOA). Specifically, the ISPC effect was observed for the -200 ms (word-first), and 0 ms (simultaneous) conditions, but disappeared in the +200 ms (color-first) condition. The aim of the current study was to conceptually replicate and ext...
Can Contingency Learning Alone Account for Item-Specific Control? Evidence From Within- and Between-Language ISPC Effects ATALAY, NART BEDİN; Mısırlısoy, Mine (2012-11-01) The item-specific proportion congruence (ISPC) manipulation (Jacoby, Lindsay, & Hessels, 2003) produces larger Stroop interference for mostly congruent items than mostly incongruent items. This effect has been attributed to dynamic control over word-reading processes. However, proportion congruence of an item in the ISPC manipulation is completely confounded with response contingency, suggesting the alternative hypothesis, that the ISPC effect is a result of learning response contingencies (Schmidt & Besner...
Uyarıcı-tepki izlerliği bulunduğunda bağlam tekrar sıralı uyumluluk etkisini değiştirmez İnan, Aslı Bahar; Atalay, Nart Bedin; Mısırlısoy, Mine (2018-06-01) Sıralı Uyumluluk Etkisi (SUE) uyumlu denemelere kıyasla, uyumsuz denemeleri izleyen uyumluluk etkisinin daha düşük olması olarak tanımlanır. Bağlam tekrarının SUE üzerindeki etkisi iki deneyde incelenmiştir. İki deneyde de dört renkli Stroop görevi kullanılmıştır. Uyarıcılar iki kümeye ayrılmıştır. Birinci kümedeki uyarıcılar için uyarıcı ve bağlam arasında bir izlerlik yoktur. İkinci kümedeki uyarıcılar için ise bu türden bir izlerlik vardır. Bağlamsal özellik olarak, birinci deneyde büyük ve küçük harf, i...
Is spatial uncertainty necessary for the context specific proportion congruency effect? Bozkurt, Özge; Mısırlısoy, Mine; Department of Psychology (2019) Cognitive control is generally measured with the Stroop effect which is signified by slow responses in the incongruent (the word and color mismatch) items. The magnitude of the Stroop effect is modulated by experimental manipulations, for instance it is reduced by presenting items in mostly incongruent contexts as compared to mostly congruent contexts. The difference between the Stroop effects observed in these contexts is called the context specific proportion congruency (CSPC) effect. A large number of CS...
