Color Images More Memorable Than Black and White

07.05.2002


Psychologists have found that colors enhance an individual’s visual memory. From a series of experiments, researchers learned that subjects were more likely to recall the color version of an image than the same scene in black and white. The results, which appear in the May issue of the journal Experimental Psychology: Learning, Memory and Cognition, also indicate that natural colors make a difference. A photo of a landscape with a green sky, for example, will not lodge as effectively in the brain as the same scene with a blue sky.



Felix Wichmann of the Max Planck Institute for Biological Cybernetics and his colleagues conducted five experiments, using subjects with normal vision. Participants initially viewed 48 images, half in color and half in black and white. The picture subjects fell into four different categories: landscapes, flowers, rock formations and man-made objects. Each category provided a different check on the results. For example, the flower pictures varied in terms of color, not shape, but those of rock formations offered the opposite. After presenting these images, the team mixed in 48 new scenes, showed the entire set of 96, and then recorded whether the subjects remembered the originals. The color images, they found, made much longer-lasting impressions than did the black-and-white ones.

To assess whether the visual memory system treats natural color and false color differently, the researchers presented subjects with altered images, such as scenes with reddish grass. They found that people did not remember these scenes any better than they did the black-and-white versions. According to study co-author Karl Gegenfurtner, this indicates that the visual memory system is tuned to the color schemes of the natural world. "If stimuli are too strange," Gegenfurtner says, "the system simply doesn’t engage them as well." Advertising or design industries might do well to take note of the findings. To catch someone’s eye, bright colors might be best, but if "the aim is more to have an image ’stick’ in the viewer’s memory," Wichmann suggests, "unnatural colors may not be suitable.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
