    PsychoPy is an open-source software for creating experiments in behavior science. It is written in Python for the most part and has been actively developed for years. Resent releases of PsychoPy add support for Python3, creating browser-based experiments and sharing experiments on the web. In addition, a new online service named Pavlovia was launched to support browser-based experiment and experiment sharing. This article introduces current status of these new features. PsychoPy now works with Python3 though some hardware incompatibility and bugs remain. Experiments composed of basic components of PsychoPy Builder can be performed on web browsers. Users can search and share experiments registered on Pavlovia if allowed by the owner.

    Eye movement analysis is effective for investigating visual perception and cognition. The cost of conducting eye movement studies has decreased as a result of the recent release of low-cost commercial and open-source eye trackers. However, synchronizing visual stimulus presentation with eye movement recording is still difficult, particularly if the eye tracker does not come with a practical application programming interface. This paper introduces a Matlab/Octave toolbox named Sgttoolbox, which works in conjunction with the widely used experiment control library Psychtoolbox to control a cross-platform open-source eye tracker named SimpleGazeTracker, which is an eye-tracking application of GazeParser software. Hardware and software requirements for Sgttoolbox and its main functions are described. A test of temporal accuracy showed that eye movement sampling frequency was stable when stimulus presentation and recording were performed on a single PC, although better performance was obtained when presentation and recording were performed on separate PCs. Transferring the latest eye position from SimpleGazeTracker to Psychtoolbox script takes 2 to 4 ms on average, which causes a delay in drawing multiple visual stimuli when recording and stimulus presentation were performed on a single PC. When such a transfer delay is not importnat, Sgttoolbox would be a good choice for Psychtoolbox users who wish to conduct eye-tracking studies.

    Eye movement analysis is an effective method for research on visual perception and cognition. However, recordings of eye movements present practical difficulties related to the cost of the recording devices and the programming of device controls for use in experiments. GazeParser is an open-source library for low-cost eye tracking and data analysis; it consists of a video-based eyetracker and libraries for data recording and analysis. The libraries are written in Python and can be used in conjunction with PsychoPy and VisionEgg experimental control libraries. Three eye movement experiments are reported on performance tests of GazeParser. These showed that the means and standard deviations for errors in sampling intervals were less than 1 ms. Spatial accuracy ranged from 0.7 degrees to 1.2 degrees, depending on participant. In gap/overlap tasks and antisaccade tasks, the latency and amplitude of the saccades detected by GazeParser agreed with those detected by a commercial eyetracker. These results showed that the GazeParser demonstrates adequate performance for use in psychological experiments.

    Saccade trajectory often curves away from a previously attended, inhibited location. A recent study of curved saccades showed that an inhibitory effect prevents ineffective reexamination during serial visual search. The time course of this effect differs from that of a similar inhibitory effect, known as inhibition of return (IOR). In the present study, we examined whether this saccade-related inhibitory effect can operate in an object-based manner (similar to IOR). Using a spatial cueing paradigm, we demonstrated that if a cue is presented on a placeholder that is then shifted from its original location, the saccade trajectory curves away from the original (cued) location (Experiment 1), yet the IOR effect is observed on the cued placeholder (Experiment 2). The inhibitory mechanism that causes curved saccades appears to operate in a location-based manner, whereas the mechanism underlying IOR appears to operate in an object-based manner. We propose that these inhibitory mechanisms work in a complementary fashion to guide eye movements efficiently under conditions of a dynamic visual environment.

    A saccade trajectory often curves away from the location of a non-target stimulus that appears before saccade execution. Spatial inhibition may prevent the saccade from moving toward the non-target stimulus. However, little is known about how simultaneous inhibition for multiple locations affects saccade trajectories. In this study, we examined the effects from two inhibited locations on saccade trajectories. The results show that the saccade trajectories depend on the inhibited locations, and the effect of inhibiting two locations on the trajectory was a summation of the effect of inhibiting each location. A simulation study using the initial interference model also suggests that the effect of each inhibition was summed up to modulate the initial saccade direction. (C) 2007 Elsevier Ltd.

    Neuropsychological studies of patients with damage to either the temporal or parietal region have suggested that these areas can be broadly divided into two functionally different pathways, a ventral what pathway for feature-related object vision and a dorsal where pathway for motor-oriented spatial vision (Milner and Goodale 1995 Mishkin and Ungerleider 1982). This is a reasonable separation since humans must resolve what an object is regardless of where it is to achieve object recognition, and vice versa to plan body actions in relation to the object. Neuroanatomical studies in the monkey cerebral cortex have demonstrated that parietal and temporal cortical areas are heavily connected with each other (Felleman and Van Essen 1991). Given the similarity between human and monkey cortical architecture (Van Essen 2003), it is expected that human temporal and parietal areas also have similar inter-connections. Such interconnections would imply potential interactions between the temporal and parietal areas. However, it remains unclear how deeply these areas actually interact with each other. Concerning this question, we report recent studies suggesting that illusory perception of an object location called saccadic compression of visual space affects the perception of object shapes.

    A recent study proposed that saccade trajectories often curve away from previously fixated locations during visual search because of the inhibitory mechanism which prevents inefficient reexamination of rejected distractors. In the present study, we examined whether visual contexts influence saccade trajectories as is the case with other inhibitory effects in visual search (e.g., inhibition of return). Computer-generated natural scenes were used as search stimuli and participants were required to look for a toy car in the scene. The results showed that the saccade trajectories were affected by at least three previous fixations and the effect decreased exponentially with the number of intervening fixations. These results are consistent with the findings in the previous study using abstract stimuli (the O among Cs search task). The relationships between saccade curvature and other inhibitory effects in visual search are discussed.

    Perisaccadic mislocalization' is an illusion in which a stimulus presented briefly near the time of saccade onset is mislocalized. The amount of mislocalization depends on the stimulus location and the stimulus onset time relative to saccade onset. It is unclear whether perisaccadic mislocalization distorts the shape perception of a single object. To investigate this problem, we asked participants to report whether the apparent shape of a triangle presented for 10 ins before saccade was slanted in the same direction or the opposite direction as the saccade. The results showed that the apparent shape of the triangle was distorted in the direction opposite to the saccade. We compared this apparent distortion with the mislocalization of a perisaccadic vertical bar, and found that the time-course and direction of the distortion were similar, although the amount of distortion was smaller for the triangle. A hypothetical explanation for these results based on the forward/inverse optics model was discussed.

    Recent studies have shown that the saccade trajectory often curved away from an object that was previously attended but irrelevant to the current saccade goal. We investigated whether such curved saccades occur during serial visual search, which requires sequential saccades possibly controlled by inhibition to multiple locations. The results show that the saccade trajectories were affected by at least three previous fixations. Furthermore, the effect of the previous fixations on saccade trajectories decreased exponentially with time or the number of intervening saccades. The relationship between the curved saccade trajectory and inhibition of return during serial visual search was discussed. (c) 2006 Elsevier Ltd. All rights reserved.

    Recent studies have suggested that the apparent shape of a perceptually organized object flashed immediately before saccade is not distorted although a perisaccadic flash is mislocalized as if the visual space is compressed toward the goal of the saccade. We report that the apparent width of a Kanizsa illusory rectangle flashed in the perisaccadic period was compressed as much as that of a control stimulus that did not induce illusory rectangle, while that of a rectangle with real contour was less compressed. Our results imply that the process of saccadic compression of visual space completes faster than the interpolation process of illusory contours. (C) 2004 Elsevier Ltd. All rights reserved.

    We investigated the perceived locations of two stimuli flashed successively near the time of saccade execution in a dark room. The inter-stimulus interval (ISI) between the flashes ranged from 80 to 240 ms. The results show that when the ISI was 120 ms or shorter, perceived locations of the flashes interacted with each other so that the perceived distance between them was equal to the distance between these flashes on the retina. When the ISI was 240 ms, this interaction was weak. These results suggest two hypotheses. Firstly, the relation of retinal locations of flashes is a strong cue for perceiving the flash locations when the ISI is shorter than about 120 ms. Secondly, the process of perceiving or memorizing a flash location requires some time. Therefore, the perceived location of the succeeding flash affects that of the preceding flash when the ISI as shorter than about 120 ms. (C) 2002 Elsevier Science Ltd. All rights reserved.

    Based on localization error for a single perisaccadic flash, eye position signal is supposed to change more slowly than physical eye position. Nevertheless, a flicker is not perceived as moving in accordance with localization error for a single flash. We carried out two experiments to investigate this problem. Experiment 1 examined how a single flash or a flicker presented before saccade was perceived. The results showed that the flicker was not perceived as moving, although mislocalization for the single flash increases gradually before saccade. Experiment 2 was a vernier test of two stimuli successively hashed before the saccade. The results showed that the point of subjective equality shifted in accordance with the mislocalization for a single perisaccadic flash when the interstimulus interval (ISI) was about 2 s; however, it did not shift when the ISI was 78 ms. Comparison between these results and previous studies suggests that the relation of the locations of successive hashes before saccade is perceived exocentrically when the ISI and stimulus onset asynchrony between flashes was short.

    視覚探索、すなわち視覚によって特定の対象を探し出す行動は、私達の日常生活において重要な行動のひとつである。視覚探索中の眼球運動は、視覚探索中に私達がどのように注意を制御しているのかを調べる重要な指標である。本研究では、眼球運動の新たな分析方法を確立するために、探索中に行われた注視に含まれる微小眼球運動の一種であるマイクロサッカードの検出を試みた。空間上の一点を注視するように求められている時のマイクロサッカードの性質については先行研究があるが、それらの研究で用いられているマイクロサッカード検出方法は本研究の対象である視覚探索課題のように自由に注視位置を変更できる状況には利用できない。そこで、本研究では自由な眼球運動の中から注視を検出するアルゴリズムと注視中のマイクロサッカードを検出するアルゴリズムを組み合わせた新たな方法を考案した。この方法を用いて「画面上に指定された対象が存在するか否か」を判断する視覚探索中に生じるマイクロサッカードを検出した結果、探索対象が存在する条件より存在しない条件の方がマイクロサッカードの発生頻度が高いという結果が得られた。両条件の課題遂行に要する時間差等を考慮しつつ詳細に分析する必要があるが、この結果は探索中の注意制御に関する重要な手掛かりがマイクロサッカードから得られる可能性を示している。次年度は実験参加者数を増やしながらさらに分析を進める予定である。

    人間の視覚において、眼球運動によって網膜像が変化しても安定した空間が知覚されることを「位置の恒常性」と呼ぶ。位置の恒常性を実現するためには、外眼筋の固有受容感覚や運動指令の遠心性コピーなどに基づいた眼球位置情報と、網膜からの視覚情報を適切に統合する必要がある。我々の日常生活において、位置の恒常性のメカニズムは正しく機能しているように感じられる。しかし、実際にはサッカードと呼ばれる随意的な眼球運動時に瞬間提示された物体が実際に提示された位置と異なる位置に知覚されるという錯視が起こることが知られている。では、人間の位置の恒常性のメカニズムが実際にはどのようなものであり、なぜ日常生活においてそのメカニズムが正しく機能するのだろうか。これらの疑問に関して、本研究ではサッカード実行直前に瞬間提示された図形がどのような形に知覚されるかを心理実験によって詳細に検証した。それらの実験の結果、「サッカード実行直前に瞬間提示された図形の形状知覚はサッカードに伴う位置の錯視の影響を受けない」という先行研究の結果がKanizsaの主観的輪郭図形の知覚については当てはまらないことが明らかになった。この結果より、サッカードに伴う位置の錯視はKanizsaの主観的輪郭図形の知覚に時間的に先行することが示唆された。また、Kanizsaの主観的輪郭図形の知覚を含む高次の形状知覚処理過程は、網膜からの視覚情報を...
