Rats were allowed to forage in a simulated natural environment made up of eight food sources (patches) each containing a fixed number of pellets. Two of the eight contained an extra supply of peanuts. The peanut patches were signaled by an olfactory/visual cue located at the bottom of the ladder leading to the patch. In successive phases the number of sessions per day, height of the patches, and availability of peanuts were manipulated. Subjects showed evidence of discrimination learning under these conditions, although the degree of discriminatory behavior varied as a function of environmental manipulations. Assessment of behavior within foraging sessions showed that subjects systematically changed their patterns of utilization of patches across time. Sampling or exploration, as well as food reinforcement, seem implicated in these results. 相似文献

The effects of a graduated prompting treatment procedure were analyzed in three phases of an experiment on the training and generalization of reaching-grasp responding in 2- to 4-year-old blind, severely or profoundly retarded children. In Phase 1, we used a multiple-baseline across-subjects design to investigate the effectiveness of the treatment on midline reach-grasp responding. In Phase 2, we used a reversal design to investigate the effects of repeated implementations and withdrawals of the treatment. In both phases, generalization to right and left positions was measured. In Phase 3, in a multiple-baseline across-responses design, the treatment was implemented in right and left positions. Also in Phase 3, shift of stimulus control from toy-sound to verbal instructions was measured. The results showed that (a) the graduated prompting procedure was effective in training reach-grasp responding in all three children; (b) for one child, the effects were durable over repeated applications of the treatment procedure, but were not maintained during withdrawals; (c) for another child, the treatment procedure was effective in teaching reach-grasp responding in all three positions; and (d) for the same child, training of reach-grasp responding generalized to toys presented without sound, given only the verbal instruction. 相似文献

New theological understanding can emerge with the advancement of scientific knowledge and the use of new concepts, or older concepts in new ways. Here, the authors present a proposal to extend the concept of “rescue and recovery” found in the United Nations Law of the High Seas, off-world and within a broader purview of other intelligent and self-aware species that humans may someday encounter. The notion of a morality that extends to off-world species is not new, but in this analysis, rescue and recovery become an imperative when any intelligent and self-aware species is in harm's way. Rescue and recovery encompass a necessary action component except perhaps in those cases where rescuers are in danger. The authors explore three biblical examples of rescue and recovery to derive a fundamental meaning of the concept. 相似文献

We applied a narrative identity approach to the study of romantic infidelity. In Study 1, participants provided narratives of the moment they discovered their partners' infidelity. In Study 2, participants were prompted for narratives of their unfaithful actions. In both studies, measures of personality traits, forgiveness, empathy, and self‐esteem were administered. Narratives were coded for themes of redemption (bad beginnings, positive endings) and exploration (engaging with the experience's emotional implications). After controlling for relevant covariates (e.g., story length), participants who formed redemptive stories of their partner's infidelity evinced higher levels of forgiveness and lower levels of empathy (Study 1), whereas participants who disclosed redemptive stories about their own infidelity demonstrated decreased forgiveness (Study 2). Across studies, exploratory narratives corresponded positively with conscientiousness. 相似文献

In this paper, the relationships between the HEXACO personality model and socio-political attitudes were investigated. It was hypothesized that the relationship between Honesty-Humility and Social Dominance Orientation (SDO) and that between Openness and Right Wing Authoritarianism (RWA) were moderated by interest in politics. Three hundred and forty-four individuals participated in the study. Results showed that Honesty-Humility affected SDO and Openness affected RWA more strongly among individuals with a higher level of interest in politics. Facet-level analyses revealed that Humility and Experiential Openness were uniquely connected to ideology. These effects were also moderated by interest in politics. 相似文献

The presence of the general factor in interest and self-efficacy assessment and its meaning are reviewed. The general factor is found in all interest and self-efficacy assessment and has been viewed as (a) a nuisance factor with little effect on assessment, (b) a variable having substantive meaning and thus worthy of including in interpretation, and (c) as systematic bias that distorts the interpretation of the meaning of assessments. The premise of this article is that each interpretation is correct but only depending upon the context of the assessment. The main implication is that narrow single content interest scales are very subject to contaminating effects of the general factor making interpretation very difficult. Methods of correcting this contamination are presented. 相似文献

The centennial exploration of the Chinese road started with the founding of the Communist Party of China (CPC). This road is essentially characterized by modernization and adapting Marxism to the Chinese context. The fundamental correlation between China’s modernization and Marxism lies in the fact that China must go through a thorough social revolution to lay the foundation for its modernization cause, which charted a historical course from new democracy to socialism. However, only adapting Marxism to the Chinese context can help China’s modernization, because it is this philosophy that is intrinsically related to China’s practice in revolution, construction and reform. The contemporary form of adapting Marxism to the Chinese context is socialism with Chinese characteristics, which holds great significance for both the Chinese nation and international socialism and the overall development of human society in the new historical phase. This is a kind of “significance for world history” because the great rejuvenation of the Chinese nation lies not only in its own development into a modern power, but also in the fact that it is actively opening up the possibility of a new type of civilization besides completing the modernization mission and obtaining achievements from modern civilization. 相似文献

Space appears today as one of the major limits of human knowledge and experience. It offers a challenge for philosophy and theology to offer answers to the questions of the other, of origins, of faith, of image of God. 相似文献

Stereotype threat—a situational context in which individuals are concerned about confirming a negative stereotype—is often shown to impact test performance, with one hypothesized mechanism being that cognitive resources are temporarily co‐opted by intrusive thoughts and worries, leading individuals to underperform despite high content knowledge and ability (see Schmader & Beilock, 2012 ). We test here whether stereotype threat may also impact initial student learning and knowledge formation when experienced prior to instruction. Predominantly African American fifth‐grade students provided either their race or the date before a videotaped, conceptually demanding mathematics lesson. Students who gave their race retained less learning over time, enjoyed the lesson less, reported a diminished desire to learn more, and were less likely to choose to engage in an optional math activity. The detrimental impact was greatest among students with high baseline cognitive resources. While stereotype threat has been well documented to harm test performance, the finding that effects extend to initial learning suggests that stereotype threat's contribution to achievement gaps may be greatly underestimated. 相似文献
