A system consisting of two Rulkov map-based neurons coupled through reciprocal electrical synapses as a simple phenomenological example is discussed. When the electrical coupling is excitatory, the square-wave bursting can be well predicted by the bifurcation analysis of a comparatively simple low-dimensional subsystem embedded in the invariant manifold. While, when the synapses are inhibitory due to the artificial electrical coupling, a fast–slow analysis is carried out by treating the two slow variables as two different bifurcation parameters. The main result of this paper is to present a mechanism for the occurrence of a kind of special elliptic bursting. The mechanism for this kind of elliptic-like bursting is due to the interaction between two chaotic oscillations with different amplitudes. Moreover, the generation of antiphase synchronization of networks lies in the different switching orders between two pairs of different chaotic oscillations corresponding to the first neuron and the second neuron, respectively. 相似文献

It is a common assumption for multiplication-solving models that single-digit multiplications are automatically retrieved. However, the experimental evidence for this is based on paradigms under suspicion. In this research, we employed a new procedure with the aim of assessing the automatic retrieval of multiplication more directly. In two experiments, multiplication automatism was studied using briefly presented primes (stimulus onset asynchrony = 48 msec) in a number-naming task. In Experiment 1, in the congruent conditions, the target and the prime were the same numbers (e.g., prime, 6; target, 6) or the target was the solution to the multiplication prime (e.g., prime, 2×3=; target, 6). In the incongruent conditions, no relationship existed between the primes and the targets (e.g., prime, 32; target, 6; or prime, 4×8=; target, 6). Experiment 2 explored the relevance of the equal sign for the multiplication-priming effect. Data showed that naming was faster when the solution of the multiplication prime matched the target, as compared with the incongruent condition (multiplication-priming effect), and that these effects were found irrespective of the presence of the equal sign. The fact that this priming effect was found even though the participants were unaware of the presentation of the primes supports the automatic character of single-digit multiplication. We conclude by arguing that this procedure is highly valuable for exploring the mechanisms involved in simple arithmetic solving. 相似文献

Johnson-Laird and Byrne distinguished ten kinds of conditionals. Their framework was the mental models theory and they attributed different combinations of semantic possibilities to those ten types of conditionals. Based on such combinations, the mental models theory has clear predictions for reasoning tasks, including those kinds of conditionals and involving reasoning schemata such as Modus Ponens, Modus Tollens, the affirming the consequent fallacy, and the denying the antecedent fallacy. My aim in this paper is to show that the predictions of the mental logic theory for those reasoning tasks are exactly the same as those of the mental models theory, and that, therefore, such tasks are not useful to decide which of the two theories is correct. 相似文献

Although Arabic is one of the most widely used languages in the world, little is known on the availability of standardized neuropsychological tests in Arabic. We review the literature published before 2016, using the keywords Arab*, cogniti*, and neuropsycholo*, as well as keywords for each Arab country. PubMed, PsycINFO, Education Source, Academic Search Complete, Education Resources Information Center, Shamaa, and Arabpsynet databases were searched, in addition to a selected number of Arabic medical and educational journals. After excluding case reports, studies conducted on Arab groups residing outside the Arab world or Israel, and studies that employed intelligence scales or cognitive screens without standardization, 384 studies were eventually reviewed. Tests with most extensive use, adaptation, validation and norming were identified. The Raven Matrices, with its variants, was the most normed cognitive test for Arab individuals (normed in 16 countries). The rate of neuropsychology publications from the Arab countries combined, per year, was less than half of that of each American journal (top 10 journals pertaining to cognition). Nonetheless, the rate in Arab countries has increased after 2010. Publications were mostly from Egypt and Saudi Arabia, but the ratio of test adaptation-to-publication was the largest in Jordan and Lebanon. Approximately half of these publications did not employ cognitive tests that were developed, translated, adapted, or standardized according to international guidelines of psychological measurement. We provide recommendations on improving clinical neuropsychology to better serve Arab patients. 相似文献

Psychotherapy research suggests that therapeutic change is associated with the emergence and development of innovative moments (IMs)—that is, exceptions to the problematic self-narrative that brought the client to therapy. This study compares two recovered cases of major depression, according to symptom measures, that presented contrasting profiles of evolution of IMs: one typical of successful therapy (Barbara), and another typical of unsuccessful therapy (Claudia). The core conflictual relationship theme (CCRT) was used to study narrative change independently of the innovative moments coding system (IMCS). The results suggest a high congruence between the IMCS and the CCRT profiles. Although Barbara presented changes in the IMCS and the CCRT in a similar way, Claudia's self-narratives (IMs and CCRT), despite symptom change, did not change. The results are discussed, considering the importance of narrative changes in recovery from depression and the maintenance of therapeutic gains. 相似文献

Knowing the place-value of digits in multi-digit numbers allows us to identify, understand and distinguish between numbers with the same digits (e.g., 1492 vs. 1942). Research using the size congruency task has shown that the place-value in a string of three zeros and a non-zero digit (e.g., 0090) is processed automatically. In the present study, we explored whether place-value is also automatically activated when more complex numbers (e.g., 2795) are presented. Twenty-five participants were exposed to pairs of four-digit numbers that differed regarding the position of some digits and their physical size. Participants had to decide which of the two numbers was presented in a larger font size. In the congruent condition, the number shown in a bigger font size was numerically larger. In the incongruent condition, the number shown in a smaller font size was numerically larger. Two types of numbers were employed: numbers composed of three zeros and one non-zero digit (e.g., 0040–0400) and numbers composed of four non-zero digits (e.g., 2795–2759). Results showed larger congruency effects in more distant pairs in both type of numbers. Interestingly, this effect was considerably stronger in the strings composed of zeros. These results indicate that place-value coding is partially automatic, as it depends on the perceptual and numerical properties of the numbers to be processed. 相似文献

Representations are not only used in our folk-psychological explanations of behaviour, but are also fruitfully postulated, for example, in cognitive science. The mainstream view in cognitive science maintains that our mind is a representational system. This popular view requires an understanding of the nature of the entities they are postulating. Teleosemantic theories face this challenge, unpacking the normativity in the relation of representation by appealing to the teleological function of the representing state. It has been argued that, if intentionality is to be explained in teleological terms, then the function of a state cannot depend on its phylogenetical history, given the metaphysical possibility of a duplicate of an intentional being that lacks an evolutionary history (Swampman). In this paper, I present a method to produce, according to our current knowledge in genetic engineering, human-like individuals who are not the product of natural selection in the required sense. This variation will be used to shed light on the main replies that have been offered in the literature to the Swampman thought experiment. I argue that these replies are not satisfactory: representations should better not depend on natural selection. I conclude that a non-etiological notion of function is to be preferred for characterizing the relation of representation. 相似文献

U.S. Latino parents can face cultural stressors in the form of acculturative stress, perceived discrimination, and a negative context of reception. It stands to reason that these cultural stressors may negatively impact Latino youth's emotional well‐being and health risk behaviors by increasing parents' depressive symptoms and compromising the overall functioning of the family. To test this possibility, we analyzed data from a six‐wave longitudinal study with 302 recently immigrated (<5 years in the United States) Latino parents (74% mothers, Mage = 41.09 years) and their adolescent children (47% female, Mage = 14.51 years). Results of a cross‐lagged analysis indicated that parent cultural stress predicted greater parent depressive symptoms (and not vice versa). Both parent cultural stress and depressive symptoms, in turn, predicted lower parent‐reported family functioning, which mediated the links from parent cultural stress and depressive symptoms to youth alcohol and cigarette use. Parent cultural stress also predicted lower youth‐reported family functioning, which mediated the link from parent cultural stress to youth self‐esteem. Finally, mediation analyses indicated that parent cultural stress predicted youth alcohol use by a way of parent depressive symptoms and parent‐reported family functioning. Our findings point to parent depressive symptoms and family functioning as key mediators in the links from parent cultural stress to youth emotional well‐being and health risk behaviors. We discuss implications for research and preventive interventions. 相似文献

The present research examines the relationship between the infrahumanization approach and the two-dimensional model of humanness: an issue that has received very little empirical attention. In Study 1, we created three unknown groups (Humanized, Animalized, and Mechanized) granting/denying them Human Nature (HN) and Human Uniqueness (HU) traits. The attribution of primary/secondary emotions was measured. As expected, participants attributed more secondary emotions to the humanized compared to dehumanized groups. Importantly, both animalized and mechanized groups were attributed similar amounts of secondary emotions. In Study 2, the groups were described in terms of their capacity to express secondary emotions. We measured the attribution of HN/HU traits. Results showed that the infrahumanized group was denied both HU/HN traits. The results highlight the importance of considering the common aspects of both approaches in understanding processes of dehumanization. 相似文献

The purpose of this study was to evaluate the effects of tact and intraverbal training on the establishment of generalized equivalence classes. Seventeen college students were exposed to tact training, listener testing, and intraverbal training (A'B’ and B'C’) in two experiments. Visual–visual matching‐to‐sample and intraverbal tests measured performances consistent with the formation of equivalence classes. Generalization was assessed with four novel sets of stimuli. In the second experiment, matching‐to‐sample tests for baseline relations (AB, BC) were eliminated to control for the possibility that equivalence classes were developed through exposure to these visual stimulus–stimulus relations. Thirteen of 17 participants passed all matching‐to‐sample and intraverbal posttests. Results suggest that when trained and emergent intraverbal relations were not maintained or were faulty, participants did not respond correctly during matching‐to‐sample posttests. 相似文献
