This work evaluated the prospect that organizational accounts of the retention of list information by monkeys might be an
artifact of familiarity with conditional relationships. Seven sophisticated macaques were trained on four five-item lists.
Each acquisition selectively excluded one of the internal conditional pairs of the typical four-problem sequence (AB,BC,CD,DE)
that defines a five-item serially ordered list. Then, all possible novel pairings and the trained pairs appeared together
in a test. After this, the previously omitted pair was trained and animals were retested. On all tasks, initial tests revealed
little organization and much intersubject variability of characteristic choice strategies, but subsequent inclusion of all
four conditional pairs always yielded organized serial choice. On both the four-problem tests and in a later retention, errors
were directly related to interitem distance between the objects paired on test trials. These results helped to specify the
conditions required for demonstration of non-human primate analogs of transitivity, and showed that even sophisticated monkeys
organize information in retention only if they know all interitem relationships.

Starting with Sigmund Freud, psychoanalysts have written on a variety of topics relating to the diplomatic and political realms; but thus far their contributions primarily have been theoretical in nature, and have offered little of practical use to most diplomats and politicians. Various psychoanalytic theories have been applied, resulting in diverse conceptualizations: Wars are inevitable because of our inherent aggressive drives; a nation-state serves a maternal function for its members; certain large groups exhibit behaviors similar to those of adolescents. Yet these ideas do not significantly help us understand day-to-day events around the world, practical political issues, or international relations and diplomatic decisions. 相似文献

Children of HIV-infected mothers have more psychosocial adjustment difficulties than do those of noninfected mothers. In this study, child psychosocial adjustment in children of HIV-infected women is examined across the three stages of HIV-infected: asymptomatic, symptomatic and AIDS. Participants were 99 HIV-infected women and 148 noninfected women. Children were not identified as being HIV infected. Mother and child reports of behavioral difficulties are compared, and competing hypotheses about mother report of child behavior difficulties are tested. Results indicate an ascending linear trend for child report of internalizing and externalizing difficulties from the noninfected stage through increasingly severe stages of HIV-infection. According to mother report, child externalizing and internalizing difficulties are nonlinear, as mothers report an increase through the infected symptomatic stage, then a decrease in the AIDS stage. Implications for assessment, prevention and intervention in families with maternal HIV infection are discussed. 相似文献

This article deals with the development of numeracy among young children of the four to seven year age group. The research investigation described had two aims: to see how early numeracy develops in children of different ages; and to see whether there are fixed points which might serve as milestones in the development of infant numeracy. The results of this investigation involving 96 children indicate a strong development of numeracy skills during this period. With reference to the literature, it is also shown that certain items of a test previously developed for this purpose may be taken as core items that do indeed represent milestones in the development of infant numeracy. 相似文献

The ability to code location in continuous space is fundamental to spatial behavior. Existing evidence indicates a robust ability for such coding by 12 months, but systematic evidence on earlier origins is lacking. A series of studies investigated 5-month-olds’ ability to code the location of an object hidden in a sandbox, using a looking-time paradigm. In Experiment 1, after familiarization with a hiding-and-finding sequence at one location, infants looked longer at an object being disclosed from a location 12 inches (30 cm) away than at an object emerging from the hiding location, showing they were able to code location in continuous space. In Experiment 2, infants reacted with greater looking when objects emerged from locations 8 inches (20 cm) away from the hiding location, showing that location coding was more finely grained than could be inferred based on the first study. In Experiment 3, infants were familiarized with an object shown in hiding-and-finding sequences at two different locations. Infants looked longer at objects emerging 12 inches (30 cm) away from the most recent hiding location than to emergence from the other location, showing that infants could code location even when events had previously occurred at each location. In Experiment 4, after familiarization with two objects with different shapes, colors, and sounding characteristics, shown in hiding-and-finding sequences in two locations, infants reacted to location violations as they had in Experiment 3. However, they did not react to object violations, that is, events in which the wrong object emerged from a hiding location. Experiment 5 also found no effect of object violation, even when the infants initially saw the two objects side by side. Spatiotemporal characteristics may play a more central role in early object individuation than they do later, although further study is required. 相似文献

The current study examined concurrent and longitudinal relations between maternal negative affective behaviour and child negative emotional expression in preschool age children with (n=96) or without (n=126) an early developmental risk, as well as the predictions of later behaviour problems. Maternal negative affective behaviour, child externalizing emotional expression, and child internalizing emotional expression were observed during a number of lab tasks at child ages 4 and 5, and child externalizing and internalizing behaviour problems were assessed via maternal questionnaire at age 6. Path analyses using structural equation modeling were utilized to test the relations among the variables at ages 4, 5, and 6. A parent‐driven model of emotion socialization emerged, wherein stronger relations were found among maternal negative affect and child externalizing emotions and behaviours than among maternal negative affect and child internalizing emotions and behaviours. Early child risk did not appear to alter the overall emotion socialization process, although higher levels of maternal and child negativity were observed for the children with a developmental risk. Results underscore the complexity of emotion socialization processes throughout the preschool period. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

Giftedness can be both an asset and a burden when gifted students respond to developmental challenges. Characteristics associated with high intellectual ability likely affect how gifted students experience social, emotional, and career development, regardless of level of academic achievement. Counselors' lack of awareness of such qualitative differences, as well as positive and negative biases, may interfere with the therapeutic relationship. Characteristics related to giftedness, vulnerabilities, concerns, and counseling strategies are the focus of this article. 相似文献

Three-generation households that include parents and grandparents raising children together have become increasingly common in China. This study examined the relations among depressive symptoms, parenting stress, and caregiver–child relationships in the mother–grandmother dyadic context. Participants were mothers and grandmothers from 136 three-generation households. Results from Actor–Partner Interdependence Mediation Modeling indicated that mothers’ depressive symptoms were indirectly related to mother–child conflict/closeness through own parenting stress; grandmothers’ depressive symptoms were indirectly related to grandmother–child conflict through own parenting stress. Mothers’ depressive symptoms were indirectly related to grandmothers’ conflict with children through grandmothers’ parenting stress, and grandmothers’ depressive symptoms were indirectly related to mothers’ conflict/closeness with children through mothers’ parenting stress. The relation between mothers’ parenting stress and mother–child closeness was stronger than the relation between grandmothers’ parenting stress and grandmother–child closeness. Findings highlight the implications of using a family system perspective and the dyadic approach in understanding and improving family functioning in Chinese three-generation households. 相似文献

The Still-Face Paradigm (SFP) designed by Tronick, Als, Adamson, Wise, and Brazelton (Tronick, E., Als, H., Adamson, L., Wise, S., & Brazelton, T. B. (1978). Infants response to entrapment between contradictory messages in face-to-face interaction. Journal of the American Academy of Child and Adolescent Psychiatry, 17, 1–13) has been used for many different purposes in over 80 empirical studies. In the current paper, the nature and correlates of infant behavior in the SFP were examined in a systematic narrative review and a series of meta-analyses. The results of the meta-analyses confirmed the classic still-face effect of reduced positive affect and gaze, and increased negative affect, as well as a partial carry-over effect into the reunion episode consisting of lower positive and higher negative affect compared to baseline. The still-face effect is very robust as it was found regardless of most sample variations such as infant gender and risk status, and regardless of most procedural variations, such as the length of the SFP episodes and the use of intervals between episodes. The few moderator effects that were found in the meta-analyses tended to put findings from the narrative review in a new perspective. Additional meta-analyses confirmed the narrative review in finding that higher maternal sensitivity predicted more infant positive affect during the still-face. Infants’ higher positive affect and lower negative affect during the still-face were predictive of secure attachment at age 1 year. The meta-analytic results for maternal depression were equivocal. Implications for future research include a need for studies testing the role of the adults’ identity (parent versus stranger, mother versus father) to elucidate the relationship-specificity of the still-face effect. Also, the role of maternal sensitivity and temperament as potential moderators of the still-face effect need to be examined further. On a procedural level, the effects of the timing of the still-face and of the duration of the reunion on infant responses deserve future research attention. 相似文献
