We evaluated the effects of tact and listener instruction on the emergence of bidirectional intraverbal relations with 6 typically developing Brazilian children, using an adapted alternating treatment design with pretest and posttest probes. In listener instruction, participants selected pictures that corresponded to spoken foreign-language words. For tact instruction, children had to vocalize foreign words in the presence of the corresponding pictures. After meeting mastery criteria, bidirectional intraverbal tests assessed vocalizations in Portuguese (native language) following the presentation of the equivalent words in English (foreign language) and vice versa. Tact instruction consistently produced higher levels of emergent intraverbal responding compared to listener instruction, confirming results from previous studies. 相似文献

Although perseverative speech is a common characteristic of individuals with high-functioning neurodevelopmental disabilities, little is known about the operant functions of these verbalizations. We conducted analogue functional analyses of perseverative speech for 2 students using reinforcement contingencies that included alone, attention, control, escape, and tangible conditions. Results showed the following patterns: attention only (Charlotte) or multiply determined including an attention function (Paul). We then tested an intervention for perseverative speech maintained by social positive reinforcement that included differential reinforcement of alternative behavior and extinction of perseverative speech for 1 participant. The intervention reduced perseverative speech, but did not increase appropriate speech until we added a prompting component. We then replicated this three-component intervention with Paul. The results showed moderate to high decreases in levels of perseverative speech and increased appropriate verbalizations in both cases. The results systematically replicated the interventions of previous studies by adding a prompting component to the intervention. 相似文献

Attitudes toward hiring people with disabilities are becoming critical for promoting diversity and egalitarianism within organizations. The few interventions designed to promote positive attitudes toward people with disabilities have relied on changing either the direction and/or the amount of thoughts people generate with regard to this discriminated, understudied group. In the present research, we examine the impact of a different psychological process of attitude change based on meta-cognition, or thinking about thinking. We used a meta-cognitive approach to changing prejudiced attitudes because thoughtful processes are often overlooked or denied with regard to this particular group. Specifically, we explored the impact of thought confidence on attitude change across two studies designed to change attitudes toward the incorporation of people with disabilities in companies. In each study, participants first generated either positive or negative thoughts about the proposal (thought valence manipulation). Then, the confidence in those thoughts was measured (Study 1) or manipulated (Study 2). In concert with the self-validation hypothesis, results showed that when thought confidence was relatively high (vs. low), thought valence had a greater impact on attitudes. Thus, thought valence was more predictive of attitudes when participants were confident in their thoughts. Specifically, confidence in thoughts enhanced persuasion for positive thoughts but reduced persuasion for negative thoughts. These findings provide insights into assessing effects of interventions aiming at improving attitudes toward the inclusion of minority groups in organizations. 相似文献

The role of landmarks in cotton-top tamarin spatial foraging: evidence for geometric and non-geometric features 总被引:4,自引:4,他引:0
We report experiments on captive cotton-top tamarins (Saguinus oedipus) designed to explore two components of spatial foraging. First, do tamarins have the capacity to extract geometric information
concerning the spatial relationship between a landmark and a piece of food located above or below it? Second, when tamarins
use a landmark to find a target location, what non-geometric features of the landmark do they encode? To explore these problems,
we created an artificial jungle environment and trained subjects to find food either above or below a target object (i.e.,
landmark). Once subjects successfully located the food, we transformed various features associated with the landmark, including
its color, orientation, and shape; we also manipulated the landmark-food reward distance, the overall shape of the jungle,
and the number and position of landmarks. Results showed that the tamarins' success in finding the food reward was not affected
by landmark color, orientation, number, or overall shape of the jungle, suggesting that with respect to the particular test
conditions, these features are not relevant to the representation of a landmark. Subjects also generalized to novel landmark-food
distances, suggesting that they had integrated geometric (i.e., above/below) with non-geometric (i.e., color/shape) features.
Performance was negatively affected by changes to the shape of the landmark, indicating that this feature is critical to the
representation of a landmark.

We explored whether rhesus monkeys (Macaca mulatta) share one important feature of human essentialist reasoning: the capacity to track category membership across radical featural transformations. Specifically, we examined whether monkeys – like children ( Keil, 1989 ) – expect a transformed object to have the internal properties of its original category. In two experiments, monkeys watched as an experimenter visually transformed a familiar fruit (e.g. apple) into a new kind of fruit (e.g. coconut) either by placing a fruit exterior over the original, or by removing an exterior shell and revealing the inside kind of fruit. The experimenter then pretended to place an inside piece of the transformed fruit into a box which the monkey was allowed to search. Results indicated that monkeys searched the box longer when they found a piece of fruit inconsistent with the inside kind, suggesting that the monkeys expected that the inside of the transformed fruit would taste like the innermost kind they saw. These results suggest that monkeys may share at least one aspect of psychological essentialism: They maintain category‐specific expectations about an object’s internal properties even when that object’s external properties change. These results therefore suggest that some essentialist expectations may emerge in the absence of language, and thus raise the possibility that such tendencies may emerge earlier in human development than has previously been considered. 相似文献

Transformations in family and work life have led to profound changes in the articulation of both spheres. The massive entry of women into the labor market, the decline of a family model based on the male provider, increasing job demands, and persistent gender inequality are factors that can generate work-family conflict and lead to feelings of guilt. Work-family guilt is a topic still rarely studied, particularly in Portugal. Given the importance of understanding the complexity of the relationships underlying the work-family interface and the lack of instruments in Portuguese to assess the feeling of guilt as it pertains to the work-family interface, our goal was to adapt the Work-Family Guilt Scale (WFGS) to the Portuguese population. Our results confirmed the two-dimensional structure of the scale with good reliability and validity. The WFGS was invariant between genders, with no significant mean differences between men and women. Convergent validity with the variables of work-to-family and family-to-work conflict and discriminant validity between the two dimensions of the WFGS was demonstrated. Use of this scale will allow the identification of feelings of guilt, which pose risks to the physical, emotional and psychological well-being of workers. Guilt feelings should, like conflict, be considered as a psychosocial risk that must be mitigated through policies and practices aimed at promoting a balance between family and working life. 相似文献

The authors examined how 2 lemur species (Eulemur fulvus and Lemur catta) reason about tools. Experiment 1 allowed subjects to use 1 of 2 canes to retrieve an inaccessible food reward. Lemurs learned to solve this problem as quickly as other primates. Experiment 2 then presented subjects with novel tools differing from the originals along one featural dimension. Subjects attended more to tools' sizes than to their colors and made no distinction between tools' shapes and textures. Experiments 3 and 4 presented problems in which some of the tools' orientations had to be modified relative to the food. Subjects performed well on these problems, sometimes modifying the position of the tool. These results are discussed in light of the performance of other primates on this task. 相似文献
