Infants' perception of directional alignment of texture elements on a spherical surface

By appropriately compressing texture elements on a circular surface, one can evoke the impression of being confronted with the depiction of a spherical object in the picture plane. According to Todd and Akerstrom (1987), the 3D perception of such an object can be eliminated if the optical elements are not sufficiently elongated or if they are not aligned with one another. In the current investigation, 4‐month‐old infants were tested for their ability to react to a disruption of the directional alignment variable. They were habituated to either a spherical surface or a surface the spatial layout of which was destroyed by reorienting the texture elements, and were afterwards tested with a further ellipsoid object and with a further flat surface. Data analysis revealed that the female infants, but not the male participants, preferred the novel posthabituation display, that is, the test stimulus which included a change in the orientational alignment of texture elements. These findings are discussed within the context of development of sensitivity to pictorial depth cues. It is possible that infants as young as 4 months of age respond to manipulations of the directional alignment factor per se, while older infants are capable of using this factor as a cue for 3D object shape.

Who's controlling whom? Infant contributions to maternal play behavior

Because the way mothers play with their children may have significant impacts on children's social, cognitive, and linguistic development, researchers have become interested in potential predictors of maternal play. In the present study, 40 mother–infant dyads were followed from child age 5–20 months. Five‐month habituation rate and 13 and 20 month temperamental difficulty were found to be predictive of maternal play quality at 20 months. The most parsimonious theoretical model was one in which habituation was mediated by temperamental difficulty in predicting mother play. Consistent with prior speculation in the literature, these data support the possibility that mothers adjust some aspects of their play behaviors to fit their children's cognitive and temperamental capabilities.

Perception of correlated attributes involving African–American and white females' faces by 10‐month‐old infants

Thirty‐two 10‐month‐olds were habituated to stimuli containing an African–American female face or a white female face paired with a specific object. Test stimuli maintained or violated habituation stimuli pairings (i.e. categories). Results add to an emerging literature showing that 10‐month‐olds perceive categories of social information based on detection of correlated attributes. Copyright © 2003 John Wiley & Sons, Ltd.     

家庭游戏中的母亲控制策略与儿童顺从行为

以42个3岁儿童及其母亲为被试,考察在家庭自由游戏中母亲的控制策略和儿童的顺从行为之间的关系。结果表明：（1）在亲子交往中,母亲使用直接命令的频次最多,间接命令次之,否定控制最少。（2）3岁儿童对母亲控制的顺从率为56．1％;在儿童的不顺从行为中,无技巧不顺从占优势,其中消极不顺从的频次最多。（3）母亲的弱控制策略与儿童的顺从行为相关最高;强控制策略与儿童的无技巧不顺从相关最高。（4）在儿童不顺从时,母亲的弱控制策略容易导致儿童的顺从行为,强控制策略则容易导致儿童的情境性顺从行为。     

Behavioral and environmental correlates of infant abuse in group- living pigtail macaques

The present study investigated the context of occurrence of infant abuse and the behavior of abusive mothers and their infants in pigtail macaques (Macaca nemestrina). Subjects were 8 abusive mothers with their infants and 8 control mother-infant pairs living in 3 captive social groups. The most common forms of abuse were infant crushing and dragging and the most common context of occurrence was social stress. Severe and mild abuse differed in the frequency but not in the type of abuse patterns. Abusive mothers had controlling parenting styles relative to nonabusive mothers, and abused infants played at a later age and less frequently than controls. This study replicates previous findings on the parenting styles of abusive macaque mothers and provides new evidence on the context of occurrence of abuse and its consequences for infant health and social development.     

记忆自然恢复的多高峰现象与记忆保持的生理节律论

以５．５～６岁幼儿为对象,自１９８９—１９９１年用三种不同性质学习材料,进行三次实验。有效被试人数为２６８,５７３,３６６人。表明学习后４０天内多次呈现记忆自然恢复高峰。１９９２年数学实验表明学习后第７天复习（高峰期）的长时记忆效果优于第５天（低谷期）。现有记忆理论无法解释本现象。提出了以学习为始点的生理活动节律对保持材料自动加固的理论。     

TEACHING GENERATIVE USE OF SENTENCE ANSWERS TO THREE FORMS OF QUESTIONS1

Three retarded and four economically disadvantaged children were taught, through modelling and reinforcement procedures, to produce complete sentences in response to three types of questions involving changes in verb inflections. To evaluate generalization of training, new but similar questions were periodically asked, answers to which were never modelled or reinforced. Modelling and reinforcement effectively taught correct sentence answers to training questions and produced new sentence answers to questions for which no specific training had been given.     

MODIFICATION OF HUMAN GASTRIC ACID SECRETION WITH OPERANT-CONDITIONING PROCEDURES1

In an attempt to control gastric acid secretion with operant-conditioning techniques, four normal women were given visual feedback on gastric pH plus money reinforcers. When money was made dependent on increased secretion in a differential-reinforcement-of-high-rates schedule, the rate of secretion of three of the four subjects increased to three times baseline. When money was then made dependent on decreased secretion in a differential-reinforcement-of-other-behaviors schedule, the rate of secretion of these three subjects returned to baseline levels. Heart rate, respiratory frequency, abdominal electromyographic activity, and stomach motility (measured by the electrogastrogram method) were not consistently correlated with acid secretion across subjects, although individual subjects showed substantial correlations between acid secretion and one or more other physiological response.     

Detection of differential item functioning in Rasch models by boosting techniques

Methods for the identification of differential item functioning (DIF) in Rasch models are typically restricted to the case of two subgroups. A boosting algorithm is proposed that is able to handle the more general setting where DIF can be induced by several covariates at the same time. The covariates can be both continuous and (multi‐)categorical, and interactions between covariates can also be considered. The method works for a general parametric model for DIF in Rasch models. Since the boosting algorithm selects variables automatically, it is able to detect the items which induce DIF. It is demonstrated that boosting competes well with traditional methods in the case of subgroups. The method is illustrated by an extensive simulation study and an application to real data.
