Following the view that individual future time perspective is an outcome of the socialization process, it was hypothesized that good contraceptors would display significantly longer future time extension than poor contraceptors. In a Planned Parenthood agency, 25 subjects from each group, constituting nearly the whole clinic population in these categories for a 3-month period, were given the Future Events Test during their clinic visits. The major hypothesis was confirmed, and also a significant tendency towards viewing future events more negatively was found among the poor contraceptors. Demographic data did not discriminate clearly between the two groups, though the poor contraceptors were somewhat younger and had a somewhat higher weekly family income. Use of personality variables in predicting birth-planning success or failure seems more promising than continued reliance solely on the sociocultural approach. Implications for screening and prevention in the interest of the individual, the family, and the community are discussed. 相似文献

Summary Acquisition of a manipulative response under contingent and non-contingent maternal social stimulation was examined in seven- and ten-month-old infants. Response acquisition was reliably deomonstrated in the case of the ten-month-old infants, but not in the case of the seven-month-old infants. However, despite no acquisition, the performance of the younger infants did differ from that obtained under non-contingent scheduling Examination of visual behaviour to the manipulandum and the feedback source revealed comparable profiles for both ages. The findings are interpreted in terms of the greater difficulty of mixed social/non-social contingency situations and discussed in the context of cognitive constraints on response acquisition in infancy.The conduct of this study was supported by a grant from the United Kingdom Social Science Research Council to H.R. Schaffer, and undertaken whilst the author was a Research Fellow in Psychology at the University of Strathclyde, Glasgow, Scotland.The author is grateful to W.M. Cheyne for advice and to Norman Sharp and Margaret Hunter who assisted with the data collection and analysis. 相似文献

Four experiments investigated the effects of labelling on the encoding and recognition of schematic faces. In Experiments I and II, hard-to-label (H) faces were recognized better after labelling than after observing, whereas easy-to-label (E) faces were not significantly affected. However, E faces were recognized better after labelling when subjects were instructed to attend carefully to all features of the faces during viewing. In Experiments III and IV, which dealt with each kind of face separately, both E and H faces were recognized better after labelling than after observing. An additional improvement in recognition all of faces was found when labelling subjects knew which label was relevant on each recognition trial and were instructed to use it. It was concluded that (a) a verbal label functions mainly to direct attention to specific facial features during viewing, (b)the effect of the label on recognition is positive or negative depending on whether or not it directs attention to features which are functional for the recognition test, (c) the label also forms part of the representation of the face in memory, and (d) a label may serve as a mediator at the time of testing, but only in the presence of specific cues. 相似文献

The “oblique effect” was studied using an embedded figures task in which complex patterns and hidden forms were rotated into different orientations. One set of stimuli (Series I) used patterns consisting either entirely of depending on rotation) horizontal and vertical line segments or entirely of obliques. A second set of stimuli (Series II) used patterns composed of horizontal, vertical, and oblique segments in equal proportions. With Series I, both form and complex pattern orientations changed with rotation. In Series II, rotation changed the orientation of the hidden forms, but not the relative proportion of contour orientations in the complex patterns. Significantly longer search times were required to find forms embedded within the obliquely oriented patterns of Series I. There were no significant differences in Series II. These results are discussed in terms of the role contextual contours may play in the detection of differently oriented form. 相似文献

Three theories of analogy have been proposed that are supported by computational models and data from experiments on human analogical abilities. In this article we show how these theories can be unified within a common metatheoretical framework that distinguishes among levels of informational, behavioral, and hardware constraints. This framework clarifies the distinctions among three computational models in the literature: the Analogical Constraint Mapping Engine (ACME), the Structure-Mapping Engine (SME), and the Incremental Analogy Machine (IAM). We then go on to develop a methodology for the comparative testing of these models. In two different manipulations of an analogical mapping task we compare the results of computational experiments with these models against the results of psychological experiments. In the first experiment we show that increasing the number of similar elements in two analogical domains decreases the response time taken to reach the correct mapping for an analogy problem. In the second psychological experiment we find that the order in which the elements of the two domains are presented has significant facilitative effects on the ease of analogical mapping. Of the three models, only IAM embodies behavioral constraints and predicts both of these results. Finally, the immediate implications of these results for analogy research are discussed, along with the wider implications the research has for cognitive science methodology. 相似文献
