We assess four common claims concerning the two-interval forced choice (2-IFC) procedure and the standard Difference Model of 2-IFC performance. The first two are (1) that it is unbiased and (2) that the structure of the 2-IFC task does not in itself alter sensitivity. The remaining two concern a claimed root 2 enhancement in sensitivity in 2-IFC relative to that measured in a Yes-No task. We review relevant past research and re-analyze seventeen experiments from previous studies across three laboratories. We then report an experiment comparing 2-IFC performance with performance in a second task designed to elucidate observers' decision processes. This second task is simply two successive Yes-No signal detection tasks with the same timing as in the 2-IFC experiment. We find little evidence supporting the claims that 2-IFC is unbiased and that it does not alter sensitivity and we also reject the two claims associated with the Difference Model as a model of performance in our own experiment.

Superior Parietal Lobule: A Role in Relative Localization of Multiple Different Elements

A. Vialatte, Y. Yeshurun, A. Z. Khan, R. Rosenholtz, L. Pisella

Summary: Simultanagnosia is a deficit in processing multiple visual elements simultaneously due to bilateral posterior parietal damage. Research found that patients with focal and bilateral SPL lesions performed slower in visual search tasks involving separable lines. When surrounded by distracters, the patient's ability to identify objects dropped, but improved when given specific search instructions.

The Effects of Spatial Attention on Temporal Integration Measured With the Ternus Display

Ilanit Hochmitz, Elisabeth Hein, Yaffa Yeshurun

Summary: This study investigates the effects of endogenous attention on temporal integration using the Ternus display, finding that directing attention to object locations in advance prolongs the period over which information is integrated, as evidenced by an increased perception of element motion.

Temporal crowding is a unique phenomenon reflecting impaired target encoding over large temporal intervals

Shira Tkacz-Domb, Yaffa Yeshurun

Summary: Temporal crowding impairs target encoding and increases substitution errors without reducing signal-to-noise ratio. It is a unique phenomenon different from ordinary masking and spatial crowding, affecting the precision of target encoding even with relatively long interitem intervals.

Inter-individual variations in internal noise predict the effects of spatial attention

Felipe Luzardo, Yaffa Yeshurun

Summary: This study found that individual levels of internal noise are correlated with the effects of sustained attention and transient attention, although in opposite directions. This highlights the intricate relations between perception and attention.

Temporal Crowding With Central Vision Reveals the Fragility of Visual Representations

Tomer Sahar, Yaffa Yeshurun

Summary: This study investigated temporal crowding, the impaired object identification when distracting objects precede and succeed the target. The study found clear evidence of temporal crowding in central vision, with reduced encoding precision as a unique characteristic. The magnitude of temporal crowding was similar in central and peripheral vision, indicating the involvement of higher visual areas. The impairment of precision emerged even when only the target contained orientation information, underscoring the importance of orientation-selective mechanisms.

The time-course of endogenous temporal attention - Super fast voluntary allocation of attention

Yaffa Yeshurun, Shira Tkacz-Domb

Summary: Voluntary temporal attention has a significant impact on perceptual processing, showing high effectiveness and a twofold faster mechanism than voluntary spatial attention. These findings challenge the common assumption that voluntary processes are inherently slow, highlighting the flexibility and dynamic nature of voluntary mechanisms.

Mapping the daily rhythmic transcriptome in the diabetic retina

Ryan P. Silk, Hanagh R. Winter, Ouria Dkhissi-Benyahya, Carmella Evans -Molina, Alan W. Stitt, Vijay K. Tiwari, David A. Simpson, Eleni Beli

Summary: This study investigates whether diabetes affects the daily rhythm of gene expression in the retina. The results show that diabetic mice exhibited phase advancement in the expression of certain genes compared to non-diabetic mice. The study also identified oxygen-sensing mechanisms and HIF1alpha as potential upstream regulators. These findings provide important insights into the development of diabetic retinopathy.

Alterations to foveal crowding with microsaccade preparation

Krishnamachari S. Prahalad, Daniel R. Coates

Summary: Visual stimuli presented around the time of a saccade can be perceived differently by the visual system, including a reduction in the harmful impact of flankers. This study investigated the effects of microsaccades on crowded stimuli placed 20 arc minutes from the center of gaze. The findings suggest two separate pre-saccadic benefits, one that regularizes the crowding zone and another that specifically benefits microsaccade targets surrounded by tangential flankers.

Success rates, near-response patterns, and learning trends with free-fusion stereograms

Chandrika Ravisankar, Christopher W. Tyler, Clifton M. Schor, Shrikant R. Bharadwaj

Summary: This study revealed that less than one-third of adults with normal binocular vision were able to successfully free-fuse random-dot image pairs and identify the embedded stereoscopic shapes. The successful participants showed a dissociation of vergence and accommodative responses, while the unsuccessful ones either exhibited strong vergence and accommodation or weak vergence and strong accommodation. Task performance of the unsuccessful cluster improved significantly with pharmacological paralysis of accommodation. A minority of participants also learned to dissociate one direction of their vergence and accommodation crosslinks with repeated free-fusion trials, optimizing their task performance.
