When Taekwondo Referees See Red, but It Is an Electronic System That Gives the Points

Previous studies in taekwondo have considered the use of the manual scoring system or the electronic system with only the use of the electronic body protector. The objective of this study was to analyze the relationship between the color protectors and success in 1,327 taekwondo matches from six World Grand Prix Series of two 4-year Olympic periods when electronic body and head protectors are used. In the total sample, the results did not show a relationship between the match outcome and the color of the protectors (p = 0.97, C = 0.001). For the individual six editions, the results showed a positive and strong relationship between wearing blue protectors and winning matches and one between wearing red protectors and winning matches (p = 0.001, C = 0.19; p = 0.001; C = 0.19). Regarding the weight categories, 8 and 5 of 48 showed higher percentages of blue and red winners, respectively. Regarding sex, male competitors showed a positive relationship between blue color and winning the match in 6 of 24 weight categories, and wearing red and winning the match was shown in 2 of 24 weight categories. Female competitors showed a positive relationship between blue color and winning the match in 2 of 24 weight categories, and wearing red and winning the match was shown in 3 of 24 weight categories. When it comes to the influence of being a seeded athlete, the results did show a significant confounding effect on the color of the protectors worn by the winner of the match in 2 of 13 weight categories in which a color effect was observed (p = 0.02, C = 0.28; p = 0.02, C = 0.28). In conclusion, wearing red does not provide a higher chance of winning the match. It seems that seeing red has a stronger effect than wearing red, especially in male contenders. Moreover, being a seeded athlete does not explain the result of the match. It seems that the introduction of the electronic helmet protector, in addition to the electronic body protector, made the scoring system more objective, decreasing the advantage of wearing red in winning matches.

The Rise, Demise, and Reprise of the Increasingly Protracted APA Journal Article?

Are APA journal articles getting longer or shorter over time? Earlier work that examined changes over time in article length in 24 APA journals (1986-2005) found that pages per article increased over time for the average journal, peaking around 2001, and then plateaued thereafter. But have these trends continued during the past 14 years? The current research extends prior work by adding additional years (1986-2019) and four additional journals (28 journals, 34 years, and 865 total observations). Multilevel growth curve analyses revealed a cubic effect of time on average article length, showing an increase in the 1980s and 1990s, a plateau or slight decline in the 2000s, and a slight increase again in the 2010s. Journal impact factors (JIFs) moderated linear growth over time; journals with higher JIFs had larger linear increases in article length. Exploratory multilevel interrupted time-series analyses suggested that the average linear increase in pages per article over time was greater after the start of psychology's credibility crisis (2012-2019) than before it (1986-2011), which may relate to an increased emphasis on reporting details and transparency. We discuss implications for article length in the contexts of publishing and psychology's ongoing credibility crisis.

Pedestrians Accept Shorter Distances to Light Vehicles Than Dark Ones When Crossing the Street

Does the brightness of an approaching vehicle affect a pedestrian's crossing decision? Thirty participants indicated their street-crossing intentions when facing approaching light or dark vehicles. The experiment was conducted in a real daylight environment and, additionally, in a corresponding virtual one. A real road with actual cars provides high face validity, while a virtual environment ensures the scenario's precise reproducibility and repeatability for each participant. In both settings, participants judged dark vehicles to be a more imminent threat-either closer or moving faster-when compared with light ones. Secondary results showed that participants accepted a significantly shorter time-to-contact when crossing the street in the virtual setting than on the real road.

Sweating the connection of uniform colours and success in sport: No evidence for the red win effect in elite women's NCAA basketball

Efforts to research the link between uniform colours and performance in sport have gained momentum in recent years demonstrating a red superiority effect. The current investigation identified a gender gap in participation between laboratory experimental studies of performance, which are dominated by women participants, and archival game analysis research, which is almost exclusively conducted in elite men's sports. To address this disparity, we conducted the first dedicated exploration of uniform colours with women's American collegiate basketball teams during the national annual tournament (NCAA) in a period spanning eight seasons (2012-19). In contrast to the evidence from experimental research, we failed to detect an effect and the results remained null when several colours were tested and ranking was considered. Based on the findings, we conclude with mounting confidence that uniform colours do not exert influence over winning in relatively long-duration, low aggression team sports with substantial physical contact. We discuss the results in relationship to the colour-in-context theory (Elliot, A. J., & Maier, M. A. (2012). Colour-in-context theory. In Advances in experimental social psychology (Vol. 45, pp. 61-125). Academic Press.) and highlight its shortcomings pertaining to sex as a moderator.

Colours' Impact on Morality: Evidence from Event-related Potentials

Black and white have been shown to be representations of moral concepts. The purpose of this study was to investigate whether colours other than black and white have similar effects on words related to morality and to determine the time course of these effects. We presented moral and immoral words in three colours (red, green and blue) in a Moral Stroop task and used the event-related potential (ERP) technique to identify the temporal dynamics of the impact of colours on moral judgement. The behavioural results showed that it took longer for people to judge immoral words than moral words when the words were coloured green than when they were red or blue. The ERP results revealed the time course of these effects. Three stages were identified in the significant effects of P200, N300 and LPC. These findings suggest a metaphorical association between the colour green and moral information.

Black and White as Valence Cues

Replication efforts involving large samples are recommended in helping to determine the reliability of an effect. This approach was taken for a study from Meier, Robinson, and Clore (2004) , one of the first papers in social cognition guided by conceptual metaphor theory, which reported that evaluations were faster when word valence metaphorically matched (e.g., a word with a negative meaning in black) rather than mismatched (e.g., a word with a negative meaning in white) font color. The present investigation was a direct large-scale replication attempt involving 980 participants who completed an experiment using web-based software and were diverse in terms of race, age, and geographical location. Words with a positive meaning were evaluated faster when font color was white rather than black and words with a negative meaning were evaluated faster when font color was black rather than white, replicating the main results of Meier et al. (2004) .

Does Recalling Moral Behavior Change the Perception of Brightness?

Banerjee, Chatterjee, and Sinha (2012) recently reported that recalling unethical behavior led participants to see the room as darker and to desire more light-emitting products (e.g., a flashlight) compared to recalling ethical behavior. We replicated the methods of these two original studies with four high-powered replication studies (two online and two in the laboratory). Our results did not differ significantly from zero, 9 out of 10 of the effects were significantly smaller than the originally reported effects, and the effects were not consistently moderated by individual difference measures of potential discrepancies between the original and the replication samples. A meta-analysis that includes both the original and replication effects of moral recall on perceptions of brightness find a small, marginally significant effect (d = 0.14 CL95 −0.002 to 0.28). A meta-analysis that includes both the original and replication effects of moral recall on preferences for light-emitting products finds a small effect that did not differ from zero (d = 0.13 CL95 −0.04 to 0.29).

Color psychology: effects of perceiving color on psychological functioning in humans

Color is a ubiquitous perceptual stimulus that is often considered in terms of aesthetics. Here we review theoretical and empirical work that looks beyond color aesthetics to the link between color and psychological functioning in humans. We begin by setting a historical context for research in this area, particularly highlighting methodological issues that hampered earlier empirical work. We proceed to overview theoretical and methodological advances during the past decade and conduct a review of emerging empirical findings. Our empirical review focuses especially on color in achievement and affiliation/attraction contexts, but it also covers work on consumer behavior as well as food and beverage evaluation and consumption. The review clearly shows that color can carry important meaning and can have an important impact on people's affect, cognition, and behavior. The literature remains at a nascent stage of development, however, and we note that considerable work on boundary conditions, moderators, and real-world generalizability is needed before strong conceptual statements and recommendations for application are warranted. We provide suggestions for future research and conclude by emphasizing the broad promise of research in this area.
