3. Yamada, Y., Publish but perish regardless in Japan, Nature Human Behaviour, https://doi.org/10.1038/s41562-019-0729-9, 3, 1035, 2019.10, [URL], Here I contend that perfectionism, nepotism, and a lack of educational opportunities to learn many things required in employment are creating a “publish but perish” situation for current PhD students. The Matthew effect (“the rich get richer”), chaperone effect (“papers of junior researchers with established PIs tend to be published in top journals”), and predatory journals also distort the validity of publication lists. I will argue that proper researcher evaluations and recruitments are based on the diversification of positions and performance indicators..

Zhu, S., Sasaki, K., Jiang, Y., Qian, K., & Yamada, Y., Trypophobia as an urbanized emotion: Comparative research in ethnic minority regions of China, PeerJ, 10.7717/peerj.8837, 8:e8837, 2020.03, Trypophobia is a strong emotion of disgust evoked by clusters of holes or round objects (e.g., lotus seed pod). It has become increasingly popular and been studied since 2010s, mainly in the West and Japan. Considering this, trypophobia might be a modern emotion, and hence urbanization possibly plays key roles in trypophobia. To address this issue, we compared the degree of trypophobia between urban and less urban people in China. In an experiment, we asked participants about their degree of discomfort from trypophobic images. The results showed that trypophobia occurred in both groups, although the effect size was larger in urban than less urban people. Moreover, post-experimental interviews and post-hoc analyses revealed that older people in less urban area did not experience as much trypophobia. Our findings suggest that trypophobia links to urbanization and age-related properties..

9. Ikeda, A., Xu, H., Fuji, N., Zhu, S., & Yamada, Y., Questionable research practices following pre-registration, Japanese Psychological Review, 62(3), 281-295, 2020.02, The credibility of psychological findings can be undermined by a history of questionable research practices (QRPs) by researchers. One remedy for this problem is the pre-registration of a study in which a research protocol is registered before beginning an experiment. However, the current style of pre-registration can be negatively affected by other QRPs. The purpose of this study was to demonstrate that researchers can engage in QRPs, even after a study has been preregistered. In this demonstration study, we used eight QRPs to obtain statistically meaningful results that supported an ad hoc hypothesis. Major system updates such as pre-registration, peer review, and evaluation are required to address these harmful practices. We hope that the present demonstration study provides momentum for further discussions on next-generation
research practices..

However, based on the arbitrary administration of experiments, I point out the risk that malicious researchers will use the benefits conversely for faking the validity of the research. In order to counter this, it is necessary to promote a great consciousness reform in the scientific community, to stop favoring only positive findings. Moreover, this article proposes separating theoretical and experimental parts as independent papers as one of future ways of academic publishing..

M., & Marmolejo-Ramos, F., Manipulating the alpha level cannot cure significance testing., Frontiers in Psychology, , 9:699., 2018.05, We argue that making accept/reject decisions on scientific hypotheses, including a recent call for changing the canonical alpha level from p = 0.05 to p = 0.005, is deleterious for the finding of new discoveries and the progress of science. Given that blanket and variable alpha levels both are problematic, it is sensible to dispense with significance testing altogether. There are alternatives that address study design and sample size much more directly than significance testing does; but none of the statistical tools should be taken as the new magic method giving clear-cut mechanical answers. Inference should not be based on single studies at all, but on cumulative evidence from multiple independent studies. When evaluating the strength of the evidence, we should consider, for example, auxiliary assumptions, the strength of the experimental design, and implications for applications. To boil all this down to a binary decision based on a p-value threshold of 0.05, 0.01, 0.005, or anything else, is not acceptable..

15. Gobara, A., Yoshimura, N., & Yamada, Y., Arousing emoticons edit stream/bounce perception of objects moving past each other., Scientific Reports, 8:5752., 2018.02, When two identical objects move toward each other, overlap completely, and continue toward opposite ends of a space, observers might perceive them as streaming through or bouncing off each other. This phenomenon is known as ‘stream/bounce perception’. In this study, we investigated the effect of the presentation of emoticons on stream/bounce perception in five experiments. In Experiment 1, we used emoticons representing anger (‘(‘∧’)’), a smile (‘(^_^)’), and a sober face (‘(°_°)’, as a control), and observers were asked to judge whether two objects unrelated to the emoticon had streamed through or bounced off each other. The anger emoticon biased perception toward bouncing when compared with the smile or sober face emoticon. In Experiments 2 and 3, we controlled for the valence and arousal of emoticons, and found that arousal influenced stream/bounce perception but valence did not. Experiments 4 and 5 ruled out the possibility of attentional capture and response bias for the emoticon with higher arousal. Taken together, the findings indicate that emoticons with higher arousal evoke a mental image of a ‘collision’ in observers, thereby eliciting the bounce perception..
16. Yamada, Y., & Sasaki, K., Involuntary protection against dermatosis: A preliminary observation on trypophobia., BMC Research Notes, 10:658. , 2017.12, Objective

Trypophobia refers to the intense negative emotions evoked by exposure to repeated visual patterns like a honeycomb. We propose a cognitive mechanism that can explain why such negative emotions are triggered by trypophobic objects, primarily through automatic and involuntary avoidance of skin diseases, which is also called as the Involuntary Protection Against Dermatosis (IPAD) hypothesis.
Results

We asked 856 participants to evaluate the discomfort evoked by trypophobic images and to report their past and current skin-related medical problems. Results showed that participants with a history of skin problems rated the pictures as evoking high discomfort as compared to those without skin problems. We conducted another survey to replicate the original survey using additional 690 participants, which confirmed the reliability of the current findings. The current study presents preliminary observational data that supports the IPAD hypothesis and suggests ways to reduce maladaptive emotional reactions toward trypophobic objects..

18. Sasaki, K., Ihaya, K., & Yamada, Y., Avoidance of novelty contributes to the uncanny valley., Frontiers in Psychology, 8:1792., 2017.09, A hypothesis suggests that objects with a high degree of visual similarity to real humans trigger negative impressions (i.e., the uncanny valley). Previous studies have suggested that difficulty in object categorization elicits negative emotional reactions to enable the avoidance of potential threats. The present study further investigated this categorization-difficulty hypothesis. In an experiment, observers categorized morphed images of photographs and human doll faces as “photograph” or “doll” and evaluated the perceived eeriness of the images. Additionally, we asked the observers to answer questionnaires on behavioral inhibition systems (BIS). The results indicated that individual differences in the BIS score were associated with enhanced eeriness in the objects with a specific human likeness. These findings suggest that the tendency to avoid a potentially threatening novel experience contributes to promoting the perceived eeriness of objects with some degree of visual similarity to real humans..

21. Okazaki, Y. S., Asakawa, A., Ishii, K., Yamada, Y., The stuffed animal sleepover: Enhancement of reading activity and the duration of effect, Heliyon, 3, e00252, 2017.02, Stuffed animal sleepover programs have been conducted by libraries worldwide. This study sought to (1) determine whether the stuffed animal sleepover program increased children’s reading and (2) examine the duration of the effect. Forty-two children who attended preschool participated in the study. The results indicated that the number of children who read picture books to stuffed animals increased following the program, but the program’s effect decreased within three days. One month later, the children were reminded of the stuffed animal sleepover program. The number of children who read picture books to stuffed animals increased again after the reminder. The results suggest that (1) stuffed animal sleepover programs can positively affect children’s reading of picture books, (2) the duration of the program’s effect can be short, and (3) reminding children of the program can be an effective strategy to revive and sustain their interest in picture books. These results are discussed in terms of the psychological characteristics of childhood..

In the present study, we examined whether visible and invisible emotional stimuli could also modulate voluntary action. After observing an emotional image (e.g., positive, neutral, or negative), partici- pants used a joystick to arbitrarily position a dot stimulus in a display. The emotional image was either masked (masked condition) or not (unmasked condition) via a continuous flash suppression technique, i.e., dynamic interocular masking. We found that in the unmasked condition, the placed position of the dot was significantly higher after observing the positive image compared with the negative image, but this difference was not present in the masked condition. Our findings suggest that conscious emotional information is necessary for activating sensorimotor representations of vertical directions, and voluntary action is performed based on these activations..
