Research on gender differences in the ability to represent horizontality in the water-level task has suggested that failure in some women may be connected with responding while envisioning the upright container as shifting to a tilted position and holding liquid in motion, rather than imaging that the container has reached the tilted position and holds(More)
Research on gender differences in visuo-spatial tasks has been mostly limited to samples of preadolescents, adolescents, and young adults. In a life span perspective, the present study attempted to complete the available information by submitting mature and elderly men and women to three tasks involving the Euclidean spatial system. Aged 40 to 61, 62 to 72,(More)
In the water-level task, it has been repeatedly shown that, compared with men, women more often fail to represent the surface of a liquid as horizontal regardless of the tilt of the container. An attempt was made to reduce this robust gender gap through the manipulation of relevant upright references conveyed both by the position of the stimuli and the(More)
The present experiment studied horizontality representation among men and women performing the water-level task either in visual conditions (the subjects saw outlines of tilted containers in which they respectively drew or set the water line) or in partially and totally haptic conditions (respectively, the subjects both saw and felt or merely felt the(More)
In comparison between male and female psychology students, a greater proportion of female students fail to represent liquid surfaces and plumb-line objects as invariably horizontal and vertical, respectively. However, the occurrence of this perplexing gender difference has not been ascertained among young adults enrolled in science programs, who should(More)
This study examines contemporary (1977-82) trapping activities in the vicinity of Kaiyuh Flats by residents of Nulato, Kaltag, Koyukuk, and Galena. It identifies which species are trapped, the scheduling of trapping activities during the season, the geographic location of trapping areas, trapping techniques as related to local ecology, and sociocultural(More)
The purpose of the present experiment was to document the cognitive processes mediating the observational learning of conservation. Two formats for measuring certainty were contrasted among nonconservers assigned to one of give groups. Under a public format, two groups used a certainty rating scale and showed the experimenter how sure they were about the(More)
