Two-bottle tests of solution acceptance were conducted in an outdoor aviary with eight common ravens (Corvus corax). Aqueous concentrations of the following chemicals were used: five common sugars, three salts, two acids, quinine hydrochloride, and sodium saccharin. Solution acceptance, as recorded for the different ravens on each test, was the percentage of preference shown for a test solution over water (comparison solution). Mid-range saccharin concentrations (0.10% to 0.80% [w/w]) were preferred over water in the tests. The preference for saccharin contrasts with all other reports on avian response to the chemical in two-bottle tests. Nonetheless, the ravens nonpreferentially accepted lower concentrations or were averse at higher concentrations to drinking sugar solutions. Similar, though more sharply marked, shifts from indifference to aversion were noted in tests with the other chemicals. The possible relevance of these latter findings to the food habits of ravens is discussed. 相似文献

G. T. scores on the Army General Classification Test (AGCT) as indicants of intelligence were correlated with scores on the Creative Imagination Test (CIT) for two groups of men differing on intelligence. Results supported the prediction of closer correspondence of intelligence and creativity scores in a low intelligence range (r = .437, p < .01) than in a high intelligence range. Intelligence was unrelated statistically to creativity (r = .10) when only the high intelligence range above 111 was considered. Guilford's triagular scatterplot conceptualization of intelligence-creativity relationship seemed most congruent with the present and earlier data. Intelligence was described as allowing the development of creativity, but not insuring such development. Personality and environmental factors may be important in creativity expression especially at upper intelligence ranges. 相似文献

The "spontaneous" tetanic attacks in magnesium (Mg) deficiency resemble those occurring in pyridoxine (Pyr) deficiency. A common mechanism may underlie both seizure patterns. Nine groups (n = 10) of male Mongolian gerbils that were Mg-deprived, Pyr-deprived, or both were used to explore this possibility. The animals were tested for spontaneous seizing in an open field at four-day intervals over 40 days. By the end of the period, 70% of the gerbils that were both Mg- and Pyr-deprived had seized, and 90% had died. One fatality, but no seizures, occurred among Pyr-deprived groups given 500 to 2,000 ppm Mg in the food. No seizures occurred among the Mg-deprived groups fed 20 to 100 ppm Pyr, though several animals given 20 ppm Pyr died. Deaths and seizures occurred within Mg-deprived groups fed more than 100 ppm Pyr. A possible role of Pyr in Mg metabolism is discussed. 相似文献

Harderian gland exudates in the male Meriones unguiculatus regulate female proceptive behavior, aggression, and investigation 总被引:1,自引:0,他引:1

Harderian gland secretions exit from the nose of Meriones unguiculatus during an autogroom (Thiessen, 1977). The exudates act as an attractant pheromone and as a thermoregulatory barrier when spread throughout the pelage. A recent study demonstrated that Harderian exudates in the male guide proceptive behavior in the female (Harriman & Thiessen, 1985). The present study replicated this finding by showing that estrous females direct fewer proceptive acts toward males lacking Harderian glands. In addition, it was found that females are more defensively aggressive toward Harderianectomized males and prefer to spend more time in the vicinity of intact males. It is speculated that Harderian spread allows the female to assess the reproductive competence of the male. 相似文献

Semantically anomolous sentences, which were spoken prosodically or in an even monotone, were presented monaurally and recalled after 5 sec of interpolated counting. Recall was superior in the Prosody condition, and performance in the Monotone condition showed no improvement when subjects were given prior knowledge of the syntactic structure. Also, a right ear advantage was found in the Prosody condition. The influence of prosody was attributed to its role in directing attention and providing continuity during memorization of the sentences, this being more effective when the information was received by the language hemisphere from the right ear. 相似文献
