Two experiments tested a hypothesis that reducing demands on executive control in a Dimensional Change Card Sort task will lead to improved performance in 3-year-olds. In Experiment 1, the shape dimension was represented by two dissimilar values (stars and flowers), and the color dimension was represented by two similar values (red and pink). This configuration of stimuli rendered shape more sa...

This is my world now. It's all I have left. You see, I'm old. And I'm not as healthy as I used to be. I'm not necessarily happy with it but I accept it. Occasionally, a member of my family will stop in to see me. He or she will bring me some flowers or a little present, maybe a set of slippers I've got 8 pair. We'll visit for a while and then they will return to the outside world and I'll be al...

“Those who have handled sciences have been either men of experiment or men of dogmas. The men of experiment are like ants; they only collect and use: the reasoners resemble spiders, which make cobwebs out of their own substance. But the bee takes a middle course, it gathers its materials from the flowers of the garden and of the field, but transforms and digests it by a power of its own.” –Sir ...

Naïve hawkmoths (Manduca sexta) learn from a single trial to approach and attempt to feed from an artificial flower of an innately unpreferred green colour even when a distractor flower with a preferred yellow colour is present. In some of the animals, the choice of the innately unpreferred colour during free-flight testing persists for several days despite not being rewarded and eventually lea...

Herein, we report a facile synthesis, characterization and dye sensitized solar cell (DSSC) application of flower-shaped ZnO nanostructures. The flower-shaped ZnO nanostructures were synthesized by low-temperature hydrothermal process and characterized in detail by several techniques. The detailed morphological studies confirmed that the flower-shaped structures are formed by the accumulation o...

by several observers for other rusts (2) has often been dletected in the distillates derived from stem rust uredospores. The fishy odor of fresh distillates frequently gives place upon dilution or storage to an odor more like the fragrance of flowers. If the odors and the biological activities of the preparations discussed in this paper are properties of the same compound(s), then the widesprea...

In this Quick Guide, Johnson introduces the reader to carrion flowers, which evolved to mimic rotting flesh. This adaptation attracts insects that facilitate pollination.

The purpose of this study is to examine the effect of direct and indirect monitoring on generosity among five-year-old preschoolers and to reveal the primary motivation for their generosity. Forty-two preschoolers completed one-shot dictator games in Condition 1 while being monitored by the experimenter (the direct monitoring condition). In Condition 2, an image of staring eyes was displayed on...

THE BATTLE FOR INFANT LIFE. To assist the Infants' Hospital, Vincent Square, in its battle for infant life, Princess Mary, its President, paid a visit on April 14 to inaugurate the pound scheme, which is an appeal to the nation for money for the general extension of the hospital, greater facilities for research, and many other improvements of which this excellent and progressive institution sta...

The flower-visiting behaviors of pollinator species are affected not only by flower traits but also by cues of predators and resident pollinators. There is extensive research into the effects of predator cues and resident pollinators on the flower-visiting behaviors of bee pollinators. However, there is relatively little research into their effects on butterfly pollinators probably because of t...
