Tachistoscopic studies of lateralization in bilinguals suggest that there is a greater degree of right hemisphere involvement in their processing of language than is typically found in monolinguals. However, most of the studies reviewed failed to control the sex, handedness, and degree of fluency of the subjects and did not include a monolingual comparison group. The present study used adult right-handed males (Portuguese-English bilinguals and English-speaking monolinguals) in a tachistoscopic word-reading task. In Experiment 1, the words from the bilinguals’ two languages were presented in mixed blocks, while in Experiment 2, they were presented in separate blocks. The results were: (1) a similar level of left hemisphere advantage for language in the bilingual and the monolingual groups, (2) no evidence of greater heterogeneity of asymmetry patterns in bilinguals, and (3) a significant correlation (r=.61) for lateralization levels of the bilinguals’ two languages. These results indicate that language is processed primarily in the left hemisphere of both bilinguals and monolinguals. 相似文献

In the United States, there is a National Registry of Evidence-Based Programs and Practices (NREPP), which is a listing of treatments and interventions in psychotherapy. In 2012, NREPP invited our research team to submit an application for registration of our short-term interpretive group therapy for patients experiencing complicated grief, which we had used since 1986. From the beginning, we experienced difficulties that seemed to be largely attributable to a lack of professional skills required of the director. The director and her team used the metaphor of American football to describe parts of application process. Despite continuing difficulties, we finally completed the application process on time. Eventually, the reviews of the application were completed and the application was approved. The information we provide in this article mainly concerns the trials and tribulations associated with the application process. Overall, the process was frustrating and time-consuming. Consideration of additional variables, such as patient personality characteristics, would likely have provided a more useful set of findings. 相似文献

The resurgence of time allocation with pigeons was studied in three experiments. In Phase 1 of each experiment, response‐independent food occurred with different probabilities in the presence of two different keylights. Each peck on the key changed its color and the food probability in effect. In Phase 2, the food probabilities associated with each keylight were reversed and, in Phase 3, food was discontinued in the presence of either keylight. The food probabilities were .25 and .75, in Experiment 1, and 0.0 and 1.0 in Experiment 2. More time was allocated to the keylight correlated with more probable food in Phases 1 and 2, and in Phase 3 resurgence of time allocation occurred for two of three pigeons in Experiment 1, and for each of four pigeons in Experiment 2. Because time had to be allocated to either of the two alternatives in Experiments 1 and 2, however, it was difficult to characterize the time allocation patterns in Phase 3 as resurgence when changeover responding approached zero. In Experiment 3 this issue was addressed by providing a third alternative uncorrelated with food such that in each phase, after 30 s in the presence of either keylight correlated with food, the third alternative always was reinstated, requiring a response to access either of the two keylights correlated with food. In this experiment, the food probabilities were similar to those in Experiment 1. Resurgence of time allocation occurred for each of three pigeons under this procedure. The results of these experiments suggest that patterns of time allocation resurge similarly to discrete responses and to spatial and temporal patterns of responding. 相似文献

Due to limited research on the experiences of students of colour in counselling programmes, counsellor educators are ill-equipped to implement strategies to promote the graduation of students of colour. In this case study, we explored the protective and risk factors for students of colour enrolled in a counselling programme in the Western U.S. Participants identified three protective factors (diversity, faculty support, and family and friends) and three risk factors (balancing family and school, disconnect from programme, and White dominance) that impacted their post-graduate experience. Implications for the retention of students of colour are discussed. 相似文献

Although primates have often been found to co-orient visually with other individuals, members of these same species have usually failed to use co-orientation to find hidden food in object-choice experiments. This presents an evolutionary puzzle: what is the function of co-orientation if it is not used for a function as basic as locating resources? Co-orientation responses have not been systematically investigated in object-choice experiments, and requiring co-orientation with humans (as is typical in object-choice tasks) may underestimate other species’ abilities. Using an object-choice task with conspecific models depicted in photographs, we provide experimental evidence that two lemur species (Eulemur fulvus, n = 4, and Eulemur macaco, n = 2) co-orient with conspecifics. Secondly, by analysing together two measures that have traditionally been examined separately, we show that lemurs’ gaze following behaviour and ultimate choice are closely linked. Individuals were more likely to choose correctly after having looked in the same direction as the model, and thus chose objects correctly more often than chance. We propose a candidate system for the evolutionary origins of more complex gaze following: ‘gaze priming.’ 相似文献

In this paper, we propose a critical classification of contemporary constructivist orientations. Our fundamental theoretical
reference is the notion of genesis, understood as the construction of reality in a way that is neither relativist nor positivist-realist.
We identify a nucleus of classic, genetic constructivism that revolves around the ideas of Baldwin, Piaget and Vygotsky and
discuss two tendencies that distort the spirit of that nucleus: objectivism and subjectivism. Objectivism rules out the psychological,
constructive activity of the subject, subordinating (or just reducing) it to objective structures either from nature (like
genetic endowment or neural functioning), or from culture (like language or social practices). Subjectivism completely detaches
the objectivity of knowledge from its construction on the part of the subject, reducing it to the mere product of individual
interest, view, or irrationality. Thus, subjectivism is the non-constructive way to conceive the subject. Then, we attempt
to show the dialectics that exists between these two tendencies and the scope of our criteria by analysing a representative
(non exhaustive) group of authors who are defined as constructivists or who bring important elements to the debate about constructivism. 相似文献

DYNAMICS OF CHOICE: RELATIVE RATE AND AMOUNT AFFECT LOCAL PREFERENCE AT THREE DIFFERENT TIME SCALES 下载免费PDF全文
Carlos F. Aparicio William M. Baum 《Journal of the experimental analysis of behavior》2009,91(3):293-317
To examine extended control over local choice, the present study investigated preference in transition as food‐rate ratio provided by two levers changed across seven components within daily sessions, and food‐amount ratio changed across phases. Phase 1 arranged a food‐amount ratio of 4:1 (i.e., the left lever delivered four pellets and the right lever one pellet); Phase 2 reversed the food‐amount ratio to 1:4, and in Phase 3 the food‐amount ratio was 3:2. At a relatively extended time scale, preference was described well by a linear relation between log response ratio and log rate ratio (the generalized matching law). A small amount of carryover occurred from one rate ratio to the next but disappeared after four food deliveries. Estimates of sensitivity to food‐amount ratio were around 1.0 and were independent of rate ratio. Analysis across food deliveries within rate‐ratio components showed that the effect of a small amount was diminished by the presence of a large amount—that is, when a larger amount was present in the situation (three or four pellets), the value of a small amount (one or two pellets) became paltry. More local analysis of visits to the levers between food deliveries showed that postfood visits following a large amount were disproportionately longer than following a small amount. Continuing food deliveries from the same source tended to make visits less dependent on relative amount, but a discontinuation (i.e., food from the other lever) reinstated dependence on relative amount. Analysis at a still smaller time scale revealed preference pulses following food deliveries that confirmed the tendency toward dependence on absolute amount with continuing deliveries, and toward dependence on relative amount following discontinuations. A mathematical model based on a linear‐operator equation accounts for many of the results. The larger and longer preference following a switch to a larger amount is consistent with the idea that local preference depends on relatively extended variables even on short time scales. 相似文献
