TL;DR: Using a graduated scale, S was required to match with his left hand the depth of three objects of equal physical depth (or thickness) held with the right hand, thus demonstrating visual capture of haptic depth.
Abstract: Using a graduated scale. S was required to match with his left hand the depth of three objects of equal physical depth (or thickness) held with the right hand. While making these haptic depth judgments the objects were viewed. Due to its optical properties. one object was of greater apparent visual depth than the other two, which served as controls. The critical object was judged to be of greater haptic depth than the control objects, thus demonstrating visual capture of haptic depth. This outcome is similar to that noted previously for haptically judged direction, size, and orientation with transformed visual input.

TL;DR: Using Australian records of human births for the first six decades of the twentieth century, the proportions of male and female births are studied in relation to the mother's age, the father's age), the parents' ages in combination, and certain other factors.
Abstract: Using Australian records of human births for the first six decades of the twentieth century, the proportions of male and female births are studied in relation to the mother's age, the father's age, the parents' ages in combination, and certain other factors. The principal data used relate to the years 1931–55, during which over 3 million children were born, yet even so the significant features are not easy to discern. Masculinity tends to fall as the age of either parent increases. But it is only average or below if one parent is old while the other is young. For high masculinity, both parents must be young. The Australian data are available in a form which enables the sex ratio to be studied also in relation to (a) the season of the year; (b) urban and rural areas; (c) the different states of the Commonwealth; (d) births inside and outside marriage; and (e) single and multiple births. When the influence of the parents' ages is eliminated, however, it does not appear as though the sex ratio varies significantly with any of these factors.

TL;DR: In this paper, it was shown that the proportion of multiple births increases with increasing age of mother up to about age 37, turns, and thereafter decreases steadily, and this effect holds for all ages of mother except those over 40.
Abstract: From statistics on Australian confinements during the period 1944–63 it seems that the following conclusions can legitimately be drawn:(1) The proportion of multiple births increases with increasing age of mother up to about age 37, turns, and decreases thereafter.(2) The proportion of multiple births increases with increasing age of father up to about age 34–38 and is fairly constant thereafter.(3) The variation with age of father, however, only arises because of the high correlation with age of mother which is the determining factor.(4) The proportion of multiple confinements increases with birth order. This effect holds for all ages of mother except those over 40 where there is no significant variation.(5) The proportion of multiple confinements decreases from the first year of marriage to the second, then increases steadily to a maximum after about 15 years of marriage and then decreases slightly.(6) The proportion of binovular twins increases steadily with increasing age of mother up to about age 37, turns, and thereafter decreases steadily.(7) The proportion of monovular twins increases slightly with increasing age of mother up to about age 37 and is fairly constant thereafter.(8) From the small amount of data it appears that the proportion of triplets also increases with increasing age of mother.

TL;DR: In this paper, a discrete-time two-sex stochastic population model is developed, where all entities (single males, single females, or couples) are grouped according to their ages, and during a unit time interval, each entity has a choice of several outcomes with fixed conditional probabilities.
Abstract: A discrete-time two-sex stochastic population model is developed. All entities (single males, single females, or couples) are grouped according to their ages, and during a unit time interval, each entity has a choice of several outcomes with fixed conditional probabilities. The model assumes that the number of marriages between men aged x and women aged y is equal to the minimum of the number of men aged x desiring marriage with a woman aged y and the number of women aged y desiring marriage with a man aged x. It follows that if a large excess of males of a11 ages is maintained in the population, the female component grows as a multi-type Galton-Watson process. Under such circumstances, the females have perfect freedom in their choice of marriage partner, and the use of a multi-type Galton-Watson process is very realistic. The same result is true for the male component of the population. Ir there are no males (or females) , no marriages take place, so the model is realistic on this score also. A complex computer program is described, and a detailed numerical example given.

TL;DR: The GA3 response in excised γ coleoptiles is not inhibited by FUDR, confirming that DNA synthesis is not required for GA3-induced elongation in γColeoptile, and is remarkably similar to that in normal coleOptiles.
Abstract: γ-irradiated wheat seed (500 kr) produces coleoptiles that grow without cell division or DNA synthesis. Apart from an initial 24-hr delay in growth, intact γ coleoptiles have a pattern of cell elongation similar to normal coleoptiles. The elongation of coleoptiles excised at a size of 2 mm, when the cells are small and just prior to entering a rapid elongation phase, is promoted by kinetin and gibberellic acid (GA3). Elongation of coleoptiles excised at 8 mm, when the cells are larger and in the rapid elongation phase, is promoted by indoleacetic acid (IAA). This sequential response to growth substances in γ coleoptiles is remarkably similar to that in normal coleoptiles. The GA3 response in excised γ coleoptiles is not inhibited by FUDR, confirming that DNA synthesis is not required for GA3-induced elongation in γ coleoptiles.
TL;DR: Bis-ligand cobalt(II) complexes of 2,4,6-tris(2-pyridyl)-1,3,5-triazine and 2, 3,5,6.tetrakis(1,2,5)-pyrazine have been prepared in this paper.
Abstract: Bis-ligand cobalt(II) complexes of 2,4,6-tris(2-pyridyl)-1,3,5-triazine and 2,3,5,6.tetrakis(2-pyridyl)pyrazine have been prepared. The conductivities of the complexes in nitromethane solution correspond to values expected for bi-unielectrolytes. The temperature dependence of their magnetism has shown that in some instances there exists a spin-state equilibrium in the metal atom while in others the metal atom is spin-free and Curie-Weiss laws are obeyed.
TL;DR: It is shown that central regulation of food and water intake in the rat is, at least partly, under the control of two separate, if anatomically overlapping, neural circuits.
Abstract: IT is generally considered that central regulation of food and water intake in the rat is, at least partly, under the control of two separate, if anatomically overlapping, neural circuits. The feeding circuit is selectively sensitive to adrenergic stimulation and the drinking circuit is activated by cholinergic stimulation1,2.
TL;DR: An experiment shows that earlier exposure to a similarly tilted room produces the same direction of change in apparent verticality when a luminous bar is adjusted in darkness, suggesting that illusory effects persist after the conditions inducing them are removed.
Abstract: Asch and Witkin showed that when an observer adjusted a bar on the far wall of a miniature room tilted at 22° laterally, the apparent vertical of the bar was displaced about 10°–14° in the direction of room tilt1. We report here an experiment which shows that earlier exposure to a similarly tilted room produces the same direction of change in apparent verticality when a luminous bar is adjusted in darkness. This experiment included appropriate controls for the occurrence of a spatial after-effect2,3, and so the data suggest that illusory effects persist after the conditions inducing them are removed.
TL;DR: In this article, an investigation was made of pupillary reactions to word stimuli presented both visually and auditorily, and the ability to discriminate between groups on this basis was explored, together with the relationships between pupil reactivity and neuroticism scores.
Abstract: An investigation was made of pupillary reactions to word stimuli presented both visually and auditorily. The ability to discriminate between groups on this basis was explored, together with the relationships between pupil reactivity and neuroticism scores. The study showed that repetition results in diminution of response; that the choice of words is critical but it does appear possible to discriminate between groups; that neuroticism seems to bear some relationship to response manner and that serial order of visual/auditory presentation of stimuli does not appear to affect the direction of the response. It is suggested that the findings might find an application in clinical psychology.

TL;DR: In this paper, a simple relation between error rates using multiple t-tests and Scheffe's multiple-comparison procedure is pointed out, and an experimental error rate approach using a flexible error rate is advocated.
Abstract: A simple relation between error rates using multiple t-tests and Scheffe's multiple-comparison procedure is pointed out. Errors in the development of some new multiple-comparison procedures are indicated. An experimental error rate approach using a flexible error rate is advocated.
TL;DR: In this article, the authors reduced the equation y n = x 1-m y m to a quadratic autonomous system of differential equations in the plane and determined the main geometric features of this autonomous system.
Abstract: In the present note the equation y n = x 1-m y m is reduced, under appropriate conditions, to a quadratic autonomous system of differential equations in the plane. In pursuance of this new approach, the main geometric features of this autonomous system are determined and a method of solving it is outlined.
TL;DR: In this article, the effects of body, neck, and trunk tilt on judgments of kinesthetic verticality were compared using 104 Ss. The results showed that head tilt and body tilt produced equal and significant E effects and that trunk tilt produced no significant E effect.
Abstract: The effects of body, neck, and trunk tilt on judgments of kinesthetic verticality were compared using 104 Ss. The results showed that head tilt and body tilt produced equal and significant E effects and that trunk tilt produced no significant E effect. The data were interpreted as showing that otolith information is an important determinant of the kinesthetic E effect.
TL;DR: In this paper, Hintikka's conception of epistemic logic is discussed and a discussion of the relation between epistemic logics and epistemic reasoning is presented in the Australasian Journal of Philosophy: Vol. 47, No. 2, pp 205-208.

TL;DR: Shor's personal experiences questionnaire was given to 600 teachers' college students as discussed by the authors, and a high correspondence was found between Shor measure, the body sway test, and a measure of ease of eyeblink conditioning.
Abstract: Shor's personal experiences questionnaire was given to 600 teachers' college students. The test/retest correlation was low, and item analyses showed no consistent trends. No significant association was found between scores of the Shor measure, Eysenck's neuroticism, Eysenck's introversion/extraversion, Rorschach neuroticism, or B40 intelligence scores. A high correspondence was found between Shor measure, the body sway test, and a measure of ease of eyeblink conditioning, and an interesting but puzzling relationship was found between the Shor and achievement in teachers' college examinations at the end of first year.
