The relation between the Muller-Lyer illusion and the angle illusion was investigated experimentally. Fifteen university students estimated the apparent angles of the oblique lines and the apparent lengths of the shaft lines of the Muller-Lyer figures. In the case of the in-going Muller-Lyer figure, the angles of the oblique lines were overestimated and the lengths of the shaft lines were underestimated. In the case of the out-going Muller-Lyer figure, the angles of the oblique lines were underestimated and the lengths of the shaft lines were overestimated. It was found that the negative correlation coefficient between the angle illusion magnitudes and the Muller-Lyer illusion magnitudes was significant.

The COVID-19 pandemic has placed significant restrictions on experiments such as those using motion capture suits in the laboratory. On the other hand, the number of users of virtual reality (VR) social network services has been increasing due to the pandemic. Thus, we constructed a laboratory in VRChat, one of the VR social network services, where full-body ownership experiments can be conducted, and validated it. The subjects entered the experimental world in VRChat, changed into the experimental avatar, and participated in the experiment. The subject’s movements and the avatar were synchronized or asynchronized with 1-s delay. After 5-min ball reaching using the avatar, subjective evaluations were made regarding senses of body ownership, agency, and pseudo-haptics. In the synchronous condition, we obtained a stronger sense of body ownership, agency, and pseudo-haptic sensation than in the asynchronous condition, reproducing the results of previous studies. These results suggest that the laboratory in the public VR social network enables us to manipulate experimental conditions, and perform experiments on full-body illusion.

To explore the possibility of conducting online experiments on audiovisual crossmodal interaction, we investigated the temporal accuracy and precision of stimulus presentation in Lab.js. We measured the presentation time as well as the onset and offset timings of audiovisual stimuli in two experiments; we used three operating systems (Windows10, macOS, and iOS), three browsers (Chrome, Firefox, and OS native), and three network environments (external network, internal network, and local host). Results showed that most software environments—with the exception of iOS—provide reasonable precision, irrespective of the network environment. In contrast, the accuracy almost systematically varied depending on the combination of the operating system and the browser. These results suggest that Lab.js is suitable for audiovisual experiments to some extent if audiovisual synchronization lag is corrected based on the information provided by the Lab.js default plug-in, which can detect the user’s OS and browser. However, considering that typical user hardware/software environments are far more complex and diverse than that of this study, effective ways to control users’ experimental environments should be investigated in future studies to obtain reliable data in online experiments.

In this short article, we reviewed out studies about development of perception. At first, we explained the findings about material perception in infants. This study showed that the 3- to 4-month-old infants have a striking ability to discriminate slight image changes due to illumination that are not salient for adults. These young infants lose this ability after 5 months of age and then develop an ability to perceive distal surface properties (glossy or matte) at 7–8 months of age. Second, we discussed the relationship between visual illusion and perceptual development. We defined the concept of “pre-constancy” based on the statements of William James. Finally, we defined the characteristic of visual illusion.

This note is a short report on the activity of the Young Researchers Committee of the Japanese Psychonomic Society (JPS). As the highlighted activity of the committee, we have held the oral session of the annual meeting of JPS seven times. We also have opened a social networking account and created a portal site for psychonomic labs across the country to increase interaction. We continue to update the committee members and their selection process to increase the mobility of the members. We are developing new activities to target a wider range of young or early career researchers. In the future, this committee should become a more open, diverse, and impartial organization.

In this study, we examined the fidelity of online cognitive–behavioral experiments conducted with Japanese crowd workers. Four cognitive tasks (flanker task, mental rotation task, levels-of-processing task, and mood induction task involving the recall of autobiographical memories) were performed by Japanese crowd workers in a web-based setting and by students in a lab-based setting. We found that all task-specific effects were replicated, except mood induction did not affect perceived social support in both crowd workers and students. The present results validate the fidelity of conducting online experiments with Japanese crowd workers.

Almost all the amputees feel the existence of the amputated limb after limb amputation, which is known to be phantom limb. Many amputees can move and control their phantom limb at their will and they report that they receive sensory feedback of the phantom limb while phantom limb moving. Further, approximately 50–80% of them have pain on the amputated limb, phantom limb pain. A possible mechanism for phantom limb is that the information of the body in the amputee's brain is not updated after amputation for some reason, causing this illusory feeling of the amputated limb. This phenomenon suggests that our body perception depends largely on the body information in the brain formed from sensory information of multimodal sensors in the body. For understanding the mechanism of our perceptual system, to examine the mismatch between actual sensory information in the environment and our perception is very useful. Thus, to elucidate the phantom limb will provide us with rich information to help understand the mechanism of our body perception.

In the previous article (Kosaki, Shi, Matsui, Shimbo, & Fujimaki, 2015) we reviewed studies regarding how animals represent temporal information in classical conditioning. In this article, we first review various issues pertaining to interval timing in operant conditioning, with the main goal of providing a concise summary of procedural and theoretical developments in interval timing research. In the remainder of the article, we will review recent empirical findings and theories about the neural substrates underlying timing mechanisms both in classical and operant conditioning, and discuss how the hippocampus and striatum might contribute to different aspects of temporal information processing during conditioning. We then argue that the potentially different timing mechanisms implemented by the hippocampus and the striatum, as evidenced by the recent discovery of time cells in the hippocampus and consistent findings regarding involvement of the striatum in interval timing, might each be considered to constitute a part of functionally dissociable multiple memory systems that have been described elsewhere in the literature, particularly in the context of spatial learning and the organisation of voluntary behaviour.

Brief introduction about current trends in deep learning was intended, including such as convolutional neural networks, and regions with convolutional neural networks. They have features as end-to-end, general purposes, and implementable based on recent advances in computer science. Object recognition of convolutional neural networks overwhelmed human performance. This tidal wave might give deep impact on all the areas in psychology.

An EEG-based brain–machine interface (BMI), “Neurocommunicator” has been developed by the author's research group in AIST in order to support communication of patients with severer motor deficits. The user can select one of registered messages in real time from electroencephalography (EEG) data and express it via his/her avatar. Integration of neuroscience and psychology will contribute to the future development, at hardware, software and service levels, of Neurocommunicator toward a commercial product.

This research note reviews experimental methods to elucidate the visual processing underlying material perception, and considers how to generate experimental stimuli of three-dimensional shapes for the experiments. For generation of a computer graphics image of a three-dimensional object, it has been widely known that its shape features can affect the material appearance of the object. However, it is not established how to systematically control the shape features to investigate the effect. Here we suggest to utilize texture synthesis algorithms. Specifically, we used a height map of a three-dimensional object as a source image, and synthesized a novel height map by using a texture synthesis algorithm. We tested three algorithms to generate the height maps; i) synthesis based on image statistics, ii) example-based synthesis, and iii) synthesis using a convolutional neural network. We discuss how effective the texture synthesis algorithms are to investigate the effect of the shape features on the material perception.

Some studies have found that a neutral stimulus can become associated with caffeine or alcohol through classical conditioning. Further, several studies have shown that the taste, smell, and sight of caffeine or alcohol (e.g., decaffeinated coffee, non-alcoholic drinks) can acquire the properties of a conditioned stimulus. In human classical conditioning, a conditioning procedure (i.e., the pairing of a conditioned stimulus and unconditioned stimulus) and other factors (e.g., verbal information) are the sources of learning. In the present context, verbal information refers to whether participants are told that their drink is decaffeinated or non-alcoholic. The taste, smell, and sight of decaffeinated coffee (caffeine cue) or non-alcoholic beer (alcohol cue) can induce a conditioned response, even when participants know that the drink is decaffeinated or non-alcoholic. Therefore, in everyday life, decaffeinated coffee and non-alcoholic beer may change performance in coffee or alcohol drinkers.

Visual perception is somehow related to the function of our brain to understand the outer world where we are living. This brain function has biological significance because it successfully reconstructs the outer world in an ecologically meaningful manner: In other words, it reconstructs ‘Umwelt’ by von Uexkull. Essential components of our Umwelt are objects and their surfaces. In this article, I will introduce some of the works done by our group that are related to the neural representation of visual surfaces of objects such as color and Shitsukan, as well as the formation of visual surfaces.

Psychologists have analyzed response time data by their rules of thumb. Modern advances of statistical methods promote to create a new practice. Traditionally, outliers were discarded prior to statistical test and skewed data were converted by logarithms. Fitting approach reminds that analyzers intend to estimate parameters for RT distributions. In statistical tests, psychologists often conducted ANOVA by aggregating data across different trials in the same condition. This practice loss precision information of measurement. Linear mixed models is changing the situation. While practical issues are remain for several aspects of applying linear mixed model, consensus among psychologists would be increasingly required.

Judgments of facial impressions such as attractiveness, trustworthiness, and dominance affect wide-ranging social outcomes. Research on perceptual mechanisms in forming such impressions is therefore central to the understanding of social cognition. This article provides a brief overview of two disparate approaches to understand how people form impressions from faces: computational modeling and experimental psychological approaches. The computational modeling approach allows for identifying the links between facial features and impressions in a data-driven manner, and thus for manipulating a face along an arbitrary impression dimension. The experimental psychological approach contributes to an understanding of how we perceive facial impressions in our cognitive systems by adopting perceptual and cognitive psychological experimental paradigms. In future studies, increased theoretical and methodological cross-talk between the computational modeling and the experimental approach would benefit progress in both fields.
