A wealth of data demonstrating that monkeys and apes represent number have been interpreted as suggesting that sensitivity to number emerged early in primate evolution, if not before. Here we examine the numerical capacities of the mongoose lemur (Eulemur mongoz), a member of the prosimian suborder of primates that split from the common ancestor of monkeys, apes and humans approximately 47–54 million years ago. Subjects observed as an experimenter sequentially placed grapes into an opaque bucket. On half of the trials the experimenter placed a subset of the grapes into a false bottom such that they were inaccessible to the lemur. The critical question was whether lemurs would spend more time searching the bucket when food should have remained in the bucket, compared to when they had retrieved all of the food. We found that the amount of time lemurs spent searching was indicative of whether grapes should have remained in the bucket, and furthermore that lemur search time reliably differentiated numerosities that differed by a 1:2 ratio, but not those that differed by a 2:3 or 3:4 ratio. Finally, two control conditions determined that lemurs represented the number of food items, and neither the odor of the grapes, nor the amount of grape (e.g., area) in the bucket. These results suggest that mongoose lemurs have numerical representations that are modulated by Webers Law. 相似文献

This study investigated family interaction patterns associated with adolescent depression. Twenty adolescent–mother dyads with clinically depressed adolescents participated in the study. Twenty dyads with externalizing youths and 20 nonclinic dyads were included as controls. Dimensions of autonomy and relatedness were rated during a videotaped mother–adolescent problem-solving task. Adolescent perceptions of parent attachment were also evaluated. Results indicated that depressed adolescents and their mothers did not differ in their behavior compared with nonclinic adolescents. Dyads with externalizing adolescents showed the highest impairment in autonomy and relatedness. Depressed adolescents perceived the quality of their relationships with their parents to be impaired relative to nonclinic dyads, as did externalizing adolescents. 相似文献

Young children's everyday scientific thinking often occurs in the context of parent-child interactions. In a study of naturally occurring family conversation, parents were three times more likely to explain science to boys than to girls while using interactive science exhibits in a museum. This difference in explanation occurred despite the fact that parents were equally likely to talk to their male and female children about how to use the exhibits and about the evidence generated by the exhibits. The findings suggest that parents engaged in informal science activities with their children may be unintentionally contributing to a gender gap in children's scientific literacy well before children encounter formal science instruction in grade school. 相似文献

Why Don't Moral People Act Morally? Motivational Considerations 总被引:2,自引:0,他引:2
C. Daniel Batson & Elizabeth R. Thompson 《Current directions in psychological science》2001,10(2):54-57
Failure of moral people to act morally is usually attributed to either learning deficits or situational pressures. We believe that it is also important to consider the nature of moral motivation. Is the goal actually to be moral (moral integrity) or only to appear moral while, if possible, avoiding the cost of being moral (moral hypocrisy)? Do people initially intend to be moral, only to surrender this goal when the costs of being moral become clear (overpowered integrity)? We have found evidence of both moral hypocrisy and overpowered integrity. Each can lead ostensibly moral people to act immorally. These findings raise important questions for future research on the role of moral principles as guides to behavior. 相似文献

Within psychology there is a longstanding debate concerning whether large, fundamental differences between races and genders exist. Much of this research involves comparisons that are invidious (offensively discriminating) and supports a political ideology in which members of different groups are held to be fundamentally different, alien, and therefore destined to different spheres. In this paper, specific factors are identified that make research on group differences more likely to produce distorted and partial findings. In addition, studies are cited whose methodological strategies offer insight into the processes that create and maintain group differences. Such research may illuminate not only the differences between groups, but also the very meaning of group categories. The process of scholarly peer review should become sensitive to the features that make comparisons invidious, so as to incorporate them into the criteria used to evaluate research. 相似文献

This study investigates the use of communication technology (CT) by therapists in private practice. CT has exploded in the last decade and therapists have begun to implement this technology in their work. It is important to understand better the types of technology therapists are using and how they decide which devices are most useful for clinical practice. Additionally, the availability of the therapist has long been debated and CT provides media to make therapists readily available. Results show that therapists have boundary concerns and ethical dilemmas regarding CT and often feel unprepared to handle inappropriate out-of-session contacts when they occur. 相似文献

A modified Asch (1951) conformity paradigm was used to study the impact of social influence on reality-monitoring decisions about new items. Subjects studied pictures of some objects and imagined others. In a later test phase, they judged whether items had been perceived in the study phase, had been imagined, or were new. Critically, for some items, the subjects were informed of a confederate's response before rendering a judgment. Although the confederate was always correct when they responded to old items, for new items, the confederate responded perceived, imagined, or new, or did not respond (baseline). In two experiments, we show that memory for new items was influenced by an erroneous response of the confederate. Social conformity was reduced by undermining the credibility of the confederate (Experiments 1A and 1B), and the confederate's influence was evident even after there was only a 20-min delay between study and test (Experiment 2), when the subjects were 87% accurate on new baseline items. These experiments reveal the power of social influence on reality-monitoring accuracy and confidence. 相似文献

Friendsickness in the Transition to College: Precollege Predictors and College Adjustment Correlates
In this study friendsickness (preoccupation with and concern for the loss of or change in precollege friendships) is seen as a significant source of distress for college students, affecting college adjustment. A short‐term longitudinal study of college students (N = 70) examined associations between friendsickness, precollege predictors, and dimensions of college adjustment 10 weeks into the first semester. As hypothesized, friendsickness was associated with precollege social concerns, discrepancy between precollege expectations and college experiences, more precollege friends in the college social network, and loneliness and poor self‐esteem in college. Implications for precollege prevention of and college intervention efforts for friendsickness are discussed. 相似文献

This article offers an overview of the adjustment concerns of international students in the United States and explores venues for inclusion of this population in multicultural training and counselor competency development opportunities for graduate students. Counselor educators need to provide awareness and knowledge about the issues faced by international students within graduate course work and training models. This will ensure that counselor trainees are competent within a multicultural framework to understand the unique issues of international students and respond by providing culturally sensitive counseling services and programming. A model of programming implemented at a private university that provided a training opportunity for counselors‐in‐training is highlighted. Considerations in designing collaborative programs are also discussed. Este artículo da un resumen de las preocupaciones de ajustamiento de estudiantes intemacionales en los Estados Unidos y explora avenidas para incluir esta población en el entrenamiento y desarollo multicultural de estudiantes de consejería. Educadores de consejeros necesitan proveer consciencia e información sobre las situaciones enfrentadas por estudiantes intemacionales en el entrenamiento de estudiantes graduados. Esto asegurara la competencia multicultural de los estudiantes para que así entiendan las necesidades unicas de los estudiantes intemacionales y puedan proveer sensibilidad cultural en la consejería y programación de servicios. Este artículo describe un modelo de programación implementado en una universidad privada que entrenó a estudiantes de consejería. Además se discuten consideraciones para el diseño de programas colaborativos. 相似文献
