汉代中常侍考论

汉承秦制,设中常侍。元、成之后中常侍为加官,因"得入禁中",与皇帝关系十分密切,有代宣皇帝诏命、代表皇帝责问大臣的权力,事实上中常侍是皇帝意志的代表。东汉初,光武帝参用士人、宦官。和熹邓太后以女主称制,改用宦官为中常侍,其权力进一步扩大,甚至左右皇帝的废立和皇位的继承,对东汉的政治造成十分恶劣的影响。     

Implicit happiness and sadness are associated with ease and difficulty: evidence from sequential priming

Psychological Research - Three experiments tested the hypothesis of implicit associations between happiness and the performance ease concept and between sadness and the performance difficulty...     

PROGRAMMED INSTRUCTION AS A SOURCE OF GAIN IN COUNSELOR COMMUNICATION

This study investigated the effectiveness of programmed materials in interpersonal relations in improving the facilitation levels of counselor communication. Thirty Employment Service counselors were pre-tested by assessing response levels to representative client stimuli expression. The subjects were then given 10 hours of written, programmed instruction. Post-test scores indicated that statistically significant gains were realized in the communication of empathy and respect.     

Artificial syntactic violations activate Broca’s region

In the present study, using event-related functional magnetic resonance imaging, we investigated a group of participants on a grammaticality classification task after they had been exposed to well-formed consonant strings generated from an artificial regular grammar. We used an implicit acquisition paradigm in which the participants were exposed to positive examples. The objective of this study was to investigate whether brain regions related to language processing overlap with the brain regions activated by the grammaticality classification task used in the present study. Recent meta-analyses of functional neuroimaging studies indicate that syntactic processing is related to the left inferior frontal gyrus (Brodmann’s areas 44 and 45) or Broca’s region. In the present study, we observed that artificial grammaticality violations activated Broca’s region in all participants. This observation lends some support to the suggestions that artificial grammar learning represents a model for investigating aspects of language learning in infants [TICS 4 (2000) 178] and adults [Proceedings of the National Academy of Sciences of United States of America 99 (2002) 529].     

Self-Regulation Failure Reduces the Effect Alcohol Portrayals in Movies on Indirect Attitudes toward Alcohol

Abstract

We investigated the cognitive mechanisms underlying change in implicit cognitions following exposure to alcohol portrayals. More precisely, we tested in an experimental study whether this change depends on controlled or automatic processes by putting participants in a state of self-regulatory fatigue prior to being exposed to alcohol portrayals. Ninety participants were randomly assigned to a 2 (attitude measure: before vs after) × 2 (alcohol portrayal: yes vs no) × 2 (ego depletion: yes vs no) mixed design to assess whether the effects of alcohol portrayals affected cognitive resources. It was hypothesized that alcohol portrayals would have more of an impact on participants submitted to an ego-depletion task. We found a change in attitudes toward alcohol only for participants that had been exposed to alcohol portrayals, and who had not been cognitively depleted. These results suggest that these changes rely on controlled, resource-dependent processes rather than on purely associative and automatic processes. Implications regarding alcohol advertising effects on public health are discussed.     

Illusory motions induced by rapid displacements of the observer

Some illusory effects of movement are described that are easily observable when the subject is in rapid locomotion (driving a car or travelling on a train) and gazes fixedly at a particular point of the scene. These effects are essentially characterized by deformations and displacements of parts of the environment. It is suggested that the phenomenon responsible for them is the loss of size and position constancy, respectively. Experimental evidence indirectly validates this hypothesis, and a program of studies is now under way to further corroborate it.
