Fancy That

In 2005 Yale psychologists Deena Skolnick and Paul Bloom asked children and adults about the beliefs of fictional characters regarding other characters — both those that exist in the same world, such as Batman and Robin, and those that inhabit different worlds, such as Batman and SpongeBob SquarePants.

They found that while both adults and young children distinguish these two types of relationships, young children “often claim that Batman thinks that Robin is make-believe.”

“This is a surprising result; it seems unlikely that children really believe that Batman thinks Robin is not real,” they wrote. “If they did, they should find stories with these characters incomprehensible.”

One possible explanation is that young children can find it hard to take a character’s perspective, and so might have been answering from their own point of view rather than Batman’s. In a second study, kids acknowledged that characters from the same world can act on each other.

But this is a complex topic even for grownups. “James Bond inhabits a world quite similar to our own, and so his beliefs should resemble those of a real person. Like us, he should think Cinderella is make-believe. On the other hand, Cinderella inhabits a world that is sufficiently dissimilar to our own that its inhabitants should not share many of our beliefs. Our intuition, then, is that Cinderella should not believe that James Bond is make-believe; she should have no views about him at all.”

Does the green dot above flash before, as, or after the red dot reaches it? Most people say after, but in fact the flash occurs before the red dot arrives (below). This anomaly is known as the flash-lag effect, and its cause is unclear. Possibly it’s a sign that the visual system extrapolates the position of a moving object more readily than that of an unpredictably flashing one.

The Spool Paradox

When a thread is pulled horizontally from the underside of a wound spool, the spool rolls in the direction of the pulling force, counter to intuition. When the thread is pulled upward vertically, the spool rolls in the opposite direction.

Why the difference? The spool must rotate about its point of contact with the table, but the direction of torque, clockwise or counterclockwise, varies with the angle of the thread. Interestingly there’s a critical angle at which the spool does not roll but slides.

Voice Flowers

In 1885, seeking a way to depict vocal sounds visually, Welsh singer Megan Watts Hughes invented the eidophone, a chamber capped with an elastic membrane that would resonate when the singer sang into a tube. When she spread the disk with a thin layer of sand or glycerine, standing waves would register as visible patterns resembling forget-me-nots, daisies, marigolds, chrysanthemums, and sunflowers.

“Stepping out of doors,” she wrote, “[I] have seen their parallels living in the flowers, ferns, and trees around me; and … the hope has come to me that these humble experiments may afford some suggestions in regard to nature’s production of her own beautiful forms.”

The field of study she helped to pioneer is now known as cymatics — see Chladni Figures.

Spotted

In a 1963 issue of Bokmakierie, a magazine for birdwatchers, Frank A. Goodliffe described a curiously familiar species he called Clericus polydenominata, the “dog-collared sombre blackbird”:

Identification: Similar to common laity but plumage and behaviour should serve to differentiate. Plumage black with narrow white collar — unbroken at throat. Feet black, of leathery appearance. Beak pink — often with blueish tint during winter months. When in groups are often seen with wings folded behind rump. … Habits: Usually found congregating with flocks of common laity, the females of which are frequently seen with plumage of vivid colours. Nesting: This usually occurs close to old buildings with spires. They are usually very friendly and may be seen around nesting sites of common laity at tea-time. … Call: The voice is distinctive, commencing ‘Brrrrr–rethren’ and continuing low and pleasant — often prolonged. Usually sings in congregations.

In a private booklet published four years later, M.A. Traylor suggested that the species belonged in the family of bishop birds.
