How trial correlations and feedback shape sequential decision-making
… decisions. Two-alternative forced choice tasks (2AFC) are often used to characterize strategies subjects use to make decisions. Normative theories, which model ideal observers, have been developed for such tasks when rewards provide the sole evidence (e.g., two-armed bandit tasks). Less is known …

Contrast Sensitivity to One- and Two-Dimensional Luminance Patterns
… compared in a two-alternative forced choice (2AFC) experiment. Space-averaged luminance was also manipulated. Statistical analyses revealed a main effect of stimulus dimension (p < .05) and no effect of space-averaged luminance. The main effect of stimulus dimension was explained in terms of …

Agens-Präferenzen bei der Verarbeitung von satzinitialen Referenten mit Topikmarkierung im Japanischen?
… dadurch begründet, dass sich die Probanden bei 2AFC-Aufgaben signifikant häufiger für das Bild entschieden, auf dem das Agens des gezeigten Ereignisses identisch mit dem satzinitialen Referenten des Teilsatzes ist. Es wird angenommen, dass sich aus diesen Befunden eine allgemeine Präferenz für …

Common or separate summary statistical processes for representing average and variance?
… is called the 2 alternative-forced choice task (2AFC task). Observers had to choose which of the two sets were more similar to the distractors previously presented with. Our results from this study suggest that mean and variance representations are to some extent encoded together in the visual …

Investigating the Relationship Between Subjective Sleep Quality and Statistical Language Learning
… utilised the two-alternative forced choice (2AFC) recognition task, complemented by a confidence judgement rating. The results showed a significant learning effect above chance in both studies, highlighting adults' capability for statistical language learning. Explicit learning mechanisms …

Matching novel face and voice identity using static and dynamic facial images
… a variety of two-alternative forced-choice (2AFC) procedures to isolate the features that support accuracy. In addition, the thesis provides a clearer and more complete picture of face-voice matching ability than that available in the existing literature. Samedifferent procedures are used to …

The Neural Processing of Face-like Stimuli
… performed two-alternative forced-choice (2AFC) tasks tailored to each stimulus type. We examined whether emotional expressions could be decoded from EEG patterns within each stimulus category using leave-one-subject-out decoding, both for 4-class classification and pairwise emotion …

AP pelvis x-ray imaging on a trolley: the impact of trolley design, mattress design and radiographer practices on image quality and radiation dose
… evaluated using a 2 alternative forced choice (2AFC) method with a reference image acquired on the x-ray tabletop using 75kVp, the AEC, broad focus, 110cm SID and 3.2mmAl. Contrast to noise ratio (CNR) was also calculated. Effective dose was established by using Monte Carlo simulation software. …

Optimization of Fast MR Imaging Technologies using the Case-PDM to Quantitatively Assess Image Quality
… human observer experimental methods (DSCQS, FMT, 2AFC) to prove these methods on the contexts of human-model correlation, comparability of model evaluation scores across different image contents, and imperceptible difference threshold discrimination. To date, most objective image quality metrics …

Constraints on phonological statistical learning in adults
… Statistical learning was measured using a 2AFC task. Sixteen experiments contributed to this thesis (guide in Appendix 10). Convergent evidence suggested adults computed the single-feature bias (Experiment 1, Experiment 2, Experiment 3, Experiment 4, Experiment 9, Experiment 10, Experiment …

Perception of prosody by cochlear implant recipients
… was tested in a two-alternatives forced-choice (2AFC) test paradigm using sentences conveying either conditional or unconditional permission, agreement or approval. Word recognition was measured in an open set test paradigm using meaningful sentences. Results indicated that the deterioration …
