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 extend these previous findings to a picture-word Stroop task. Results showed that the ISPC effect changed as a function of SOA, supporting our previous results. Specifically, the ISPC effect was observed for the -200 ms and 0 ms conditions, but not when the word came too late (+200 ms). Taken together, these results suggest that the ISPC effects observed with color-word and picture-word Stroop tasks might have similar underlying mechanisms.

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...
ISPC effect is not observed when the word comes too late: a time course analysis
ATALAY, NART BEDİN; Mısırlısoy, Mine (2014-12-05)
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...
The possible effects of non-universal extra dimensions on t -> cl(i)(-)l(j)(+) and H-0 -> h(0)(A(0))l(i)(-)l(j)(+) decays in the general two Higgs doublet model
Iltan, E. O. (IOP Publishing, 2006-06-01)
We study the effects of non-universal extra dimensions on the decay widths of the lepton flavour violating (LFV) processes, t --> c l(i)(-) i l(j)(+) and H-0 --> h(0)(A(0)) l(i)(-)l(j)(+) in the general two Higgs doublet model. We consider that the extra dimensions are accessible to the standard model gauge fields and the new Higgs doublet. We observe that the LFV H-0 --> h(0)(tau(+) mu(-) + mu(+)) and H-0 --> A(0)(tau(+)mu(-) + tau(-) mu(+)) Higgs decays are sensitive to the extra dimensions, especially in...
The polarization properties of the final state partyicles in the rare radiative b-meson decays
Yılmaz, Ümit Oktay; Turan, Gürsevil; Department of Physics (2005)
A general analysis of the photon and lepton polarizations in the rare Bs ? ?l+l- decay by using the most general model independent form of the effective Hamiltonian is presented. The total and the differential branching ratios for these decays, when photon is in the positive and negative helicity states, are studied. The sensitivity of "photon polarization asymmetry" and the longitudinal, transverse and normal polarization asymmetries of final state leptons, as well as lepton-antilepton combined asymmetries...
The effect of substitutional impurities on the evolution of FeAl diffusion layer
Akdeniz, Mahmut Vedat; Mehrabov, Amdulla (Elsevier BV, 1998-2-13)
The formation and growth characteristics of Fe based aluminide diffusion layers at the Fe-Al interface have been analysed in terms of interfacial interaction potentials based on the statistico-thermodynamical theory of multicomponent alloys combined with electronic theory in the pseudopotential approximation. The pairwise interatomic interaction potentials and partial ordering energies have been calculated to predict the effect of various alloying additions on the activity coefficient of Al atoms in α-Fe0.9...
