Academic dishonesty occurs at alarming rates in higher education. In the present study, we examined predictors of academic cheating behaviors, and beliefs in the acceptability of cheating, in disliked courses at two large universities, using structural equation modeling. Perceived mastery and extrinsic goal structures were related to beliefs about cheating but not cheating behaviors. Beliefs in the acceptability of cheating were more likely to be endorsed in math and science courses. College students were more likely to cheat and to believe in the acceptability of cheating when they reported a high need for sensation. 相似文献

Circumplex structures are elements of various psychological domains. Most work focuses on assessing the circular ordering of circumplex indicators and their relationships with covariates. In this article, an extension procedure for Browne’s circumplex model is presented. Our approach models the relationships among circumplex indicators and the relationships of covariates with a latent circumplex simultaneously without affecting the circumplex indicators’ positions on the circumplex. The approach builds upon Browne’s Fourier series parameterization of a correlation function, which is used to model the latent circumplex correlation structure. It extends the shape of the correlation function to the profile of each covariate’s correlations with the circumplex. The model is specified in the framework of structural equation modeling, thereby making it possible to test various hypotheses. Procedures are presented for deriving interval estimates for the parameters that relate the covariates to the circumplex. The model is compared to other approaches for assessing the relationships of a circumplex with covariates. The results of the exemplary applications and a simulation study were in favor of the suggested model. The approach is furthermore illustrated with a real-data example, focusing on the relationships between the interpersonal circumplex and the rivalry and admiration aspects of narcissism. 相似文献

Alzheimer’s disease, the most common form of dementia is a neurodegenerative brain order that has currently no cure for it. Hence, early diagnosis of such disease using computer-aided systems is a subject of great importance and extensive research amongst researchers. Nowadays, deep learning or particularly convolutional neural network (CNN) is getting more attention due to its state-of-the-art performances in variety of computer vision tasks such as visual object classification, detection and segmentation. Several recent studies, that have used brain MRI scans and deep learning have shown promising results for diagnosis of Alzheimer’s disease. However, most common issue with deep learning architectures such as CNN is that they require large amount of data for training. In this paper, a mathematical model PFSECTL based on transfer learning is used in which a CNN architecture, VGG-16 trained on ImageNet dataset is used as a feature extractor for the classification task. Experimentation is performed on data collected from Alzheimer’s Disease Neuroimaging Initiative (ADNI) database. The accuracy of the 3-way classification using the described method is 95.73% for the validation set. 相似文献

Cognitive impairments seen in people living with HIV (PLWH) are associated with difficulties in everyday functioning, specifically driving. This study utilized speed of processing cognitive remediation therapy (SOP-CRT) with transcranial direct current stimulation (tDCS) to gauge the feasibility and impact on simulated driving. Thirty PLWH (Mage = 54.53, SD = 3.33) were randomly assigned to either: sham tDCS SOP-CRT or active tDCS SOP-CRT. Seven indicators of simulated driving performance and safety were obtained. Repeated measures ANOVAs controlling for driver’s license status (valid and current license or expired/no license) revealed a large training effect on average driving speed. Participants who received active tDCS SOP-CRT showed a slower average driving speed (p = 0.020, d = 0.972) than those who received sham tDCS SOP-CRT. Non-significant small-to-medium effects were seen for driving violations, collisions, variability in lane positioning, and lane deviations. Combination tDCS SOP-CRT was found to increase indices of cautionary simulated driving behavior. Findings reveal a potential avenue of intervention and rehabilitation for improving driving safety among vulnerable at-risk populations, such as those aging with chronic disease. 相似文献

How is beauty embodied? According to the viewpoint of embodied cognition, the aesthetic processing of words or pictographs has roots in their referential archetypes. Four experiments tested whether the beauty of referential archetypes was routinely activated during the explicit and implicit aesthetic evaluations of the font structures of concrete Chinese words and pictographs in congruent or incongruent font colour. Results showed font structures of simplified Chinese words and pictographs were judged to be more beautiful when they referred to beautiful archetypes; and this pattern was reversed when they referred to ugly archetypes. Moreover, judgement was facilitated when font colour was congruent for Chinese words and pictographs referred to beautiful archetypes. For those referred to ugly archetypes, judgement was inhibited in congruent font colour but facilitated in incongruent font colour, suggesting aesthetic perceptions of the font structures of Chinese words and pictographs were derived from their referential natural objects. The spontaneous generation hypothesis of beauty is proposed to account for these findings. 相似文献

While structured as an autobiography, this memoir exemplifies ways in which classic contributions to cybernetics (e.g., by Wiener, McCulloch & Pitts, and von Neumann) have fed into a diversity of current research areas, including the mathematical theory of systems and computation, artificial intelligence and robotics, computational neuroscience, linguistics, and cognitive science. The challenges of brain theory receive special emphasis. Action-oriented perception and schema theory complement neural network modeling in analyzing cerebral cortex, cerebellum, hippocampus, and basal ganglia. Comparative studies of frog, rat, monkey, ape and human not only deepen insights into the human brain but also ground an EvoDevoSocio view of “how the brain got language.” The rapprochement between neuroscience and architecture provides a recent challenge. The essay also assesses some of the social and theological implications of this broad perspective. 相似文献

Prior research has demonstrated the reliability and validity of the Neurological Predictor Scale (NPS) in relation to childhood brain tumor survivor outcomes; however, its use has not been examined in adult long-term survivors. The current study examines the concurrent validity of the NPS with long-term intellectual and adaptive outcomes in adult survivors of childhood brain tumors relative to individual variables alone. A total of 68 adult survivors of childhood brain tumors (M = 24 years old, SD = 4) almost 16 years post diagnosis (SD = 6) completed intellectual evaluations using the Wechsler Abbreviated Scale of Intelligence (WASI). Survivors’ adaptive functioning skills were assessed via informant structured clinical interviews (SIB-R). NPS scores were computed from data acquired from medical records. The NPS was significantly associated with intellectual (R2 = 0.208, p < .05) and adaptive outcomes (R2 = 0.30, p < .05) over and above individual risk factors. Approximately 18% of long-term survivors were identified as impaired in intellectual outcomes, and 29% were identified as impaired in adaptive functioning in everyday life skills. The NPS quantifies the cumulative effects of treatment and neurological sequelae experienced by both short- and long-term survivors of childhood brain tumors. It is a useful and easy measure to employ in clinical research that focuses on quantifying the neurological risk factors associated with long-term intellectual and adaptive functioning outcomes in adult survivors of childhood brain tumors. 相似文献

The aim of this article is to strengthen links between cognitive brain research and formal logic. The work covers three fundamental
sorts of logical inferences: reasoning in the propositional calculus, i.e. inferences with the conditional “if...then”, reasoning
in the predicate calculus, i.e. inferences based on quantifiers such as “all”, “some”, “none”, and reasoning with n-place
relations. Studies with brain-damaged patients and neuroimaging experiments indicate that such logical inferences are implemented
in overlapping but different bilateral cortical networks, including parts of the fronto-temporal cortex, the posterior parietal
cortex, and the visual cortices. I argue that these findings show that we do not use a single deterministic strategy for solving
logical reasoning problems. This account resolves many disputes about how humans reason logically and why we sometimes deviate
from the norms of formal logic.

To speak of cognitive regulation versus emotion regulation may be misleading. However, some forms of regulation are carried out by executive processes, subject to voluntary control, while others are carried out by “automatic” processes that are far more primitive. Both sets of processes are in constant interaction, and that interaction gives rise to a stream of activity that is both cognitive and emotional. Studying the brain helps us understand these reciprocal regulatory influences in some detail. Cortical activities regulate subcortical activities through executive modulation of prepotent appraisals and emotional responses. Subcortical systems regulate the cortex by tuning its activities to the demands or opportunities provided by the environment. Cortical controls buy us time, as needed for planning and intelligent action. Subcortical controls provide energy, focus, and direction, as needed for relevant emotion-guided behaviour. We review the neural processes at work in both directions of regulatory activity, looking at the anterior cingulate cortex (ACC) as a hub of cortical systems mediating downward control, and discussing limbic, hypothalamic, and brainstem systems that mediate upward control. A macrosystem that displays both directions of control includes the ACC and the amygdala within a feedback circuit whose features vary with clinical-personality differences. Developmental changes in ACC-mediated self-regulation support advances in directed attention, response inhibition, and self-monitoring. Developmental changes in amygdala-mediated self-regulation involve the compilation of meanings that direct thought and behaviour, thus consolidating individual differences over the lifespan. In this way, the capacity to exert voluntary control develops alongside the accumulation of associations that trigger the responses that demand control. The balance between these developmental progressions has implications for personality formation and mental health. 相似文献

An overview of the following three related papers in this issue presents the Emergence of Highly Complex Systems such as living
organisms, man, society and the human mind from the viewpoint of the current Ontological Theory of Levels. The ontology of
spacetime structures in the Universe is discussed beginning with the quantum level; then, the striking emergence of the higher
levels of reality is examined from a categorical—relational and logical viewpoint. The ontological problems and methodology
aspects discussed in the first two papers are followed by a rigorous paper based on Category Theory, Algebraic Topology and
Logic that provides a conceptual and mathematical basis for a Categorical Ontology Theory of Levels. The essential links and
relationships between the following three papers of this issue are pointed out, and further possible developments are being
considered. 相似文献
