Adults with mental retardation in a group home received popcorn or coffee reinforcers for sorting plastic dinnerware. In Part 1 of the experiment, reinforcers were dispensed according to a variable-interval 60-s schedule for sorting dinnerware of one color and according to a variable-interval 240-s schedule for sorting dinnerware of a different color in successive components of a multiple schedule. Sorting rates were similar in baseline, but when a video program was shown concurrently, sorting of dinnerware was more resistant to distraction when correlated with a higher rate of reinforcement. In Part 2 of the experiment, popcorn or coffee reinforcers were contingent upon sorting both colors of dinnerware according to variable-interval 60-s schedules, but additional reinforcers were given independently of sorting according to a variable-time 30-s schedule during one dinnerware-color component. Baseline sorting rate was lower but resistance to distraction by the video program was greater in the component with additional variable-time reinforcers. These results demonstrate that resistance to distraction depends on the rate of reinforcers obtained in the presence of component stimuli but is independent of baseline response rates and response–reinforcer contingencies. Moreover, these results are similar to those obtained in laboratory studies with pigeons, demonstrating that the determination of resistance to change by stimulus–reinforcer relations is not confined to controlled laboratory settings or unique to the pigeon. 相似文献

We examined the role of Pavlovian and operant relations in behavioral momentum by arranging response-contingent alternative reinforcement in one component of a three-component multiple concurrent schedule with rats. This permitted the simultaneous arranging of different response-reinforcer (operant) and stimulus-reinforcer (Pavlovian) contingencies during three baseline conditions. Auditory or visual stimuli were used as discriminative stimuli within the multiple concurrent schedules. Resistance to change of a target response was assessed during a single session of extinction following each baseline condition. The rate of the target response during baseline varied inversely with the rate of response-contingent reinforcement derived from a concurrent source, regardless of whether the discriminative stimuli were auditory or visual. Resistance to change of the target response, however, did depend on the discriminative-stimulus modality. Resistance to change in the presence of visual stimuli was a positive function of the Pavlovian contingencies, whereas resistance to change was unrelated to either the operant or Pavlovian contingencies when the discriminative stimuli were auditory. Stimulus salience may be a factor in determining the differences in resistance to change across sensory modalities. 相似文献

The information contained in DNA is not definitive, but modifiable. Indeed, the environment has the power to modify the genetic material expression without altering the DNA genes sequence. The principal environmental factors that work in this way, whether in a positive or in a negative way, are diet and stress with their ruling hormones, insulin and cortisol; these hormones are normally antagonists but, when they reach their respective resistances, they become the ubiquitary etiopathogenetic factors in bidirectional convergent relationship, each other causing the disinhibition and development of low grade systemic inflammation that opens the door to a myriad of interconnected sets of problems. Among these problems the greater one is cancer, which represents the extreme junction between hyperinsulinemia and hypercortisolemia, just because cancer cells never become insulin resistant and/or cortisol resistant. 相似文献

Existing research, policy information, and materials intended to teach child safety assumes that certain behaviours will protect children in the event that a stranger tries to abduct them. However, there is little empirical basis for these assumptions. This paper examines the effectiveness of strategies thought to increase the likelihood that a child will be able to resist an attempted stranger child abduction event. Seventy‐eight cases of stranger child abduction that occurred in the UK between 1988 and 2014, including 25 attempted cases and 53 completed cases, were examined in order to ascertain the relative prevalence of various resistance types and to assess their effectiveness of six key resistance strategies based on whether the presence or absence affected the outcome of the abduction. Results show that direct, unequivocal verbal resistance, running away, and a composite approach where the victim runs away, calls for help, and reports the offence were highly effective means of resisting an offender, whereas physical resistance, indirect verbal resistance, and non‐resistance were not effective. Female victims were almost twice as likely to employ any kind of resistance strategy against an offender as male victims were. The implications of these findings for augmenting ways in which children are taught about safety are discussed. Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

应用WHONET5.3软件对2005年1月至2007年12月检出的1749株病原菌种类、分布及其耐药性进行统计分析。结果发现院内感染病原菌以条件致病菌为主,革兰阴性菌检出率61.8%,革兰阳性菌的检出率33%,真菌检出率为5.2%。大肠埃希菌及肺炎克雷伯菌属的ESBLs阳性率分别为34.4%和48.9%,MRSA和MRCNS的检出率分别为40.8%和36.4%。大多数病原菌对抗生素产生多重耐药性。由此可见,由于临床抗生素的广泛使用,病原菌不断变迁且其耐药性逐渐上升,应加强耐药性监测及合理使用抗生素,以有效控制细菌感染和耐药性播散。 相似文献

By taking into account dissident/political and art historical interpretations of Soviet art, I analyze how polemics about
totalitarianism in the West, which generally corresponded with Cold War debates and Eastern European dissident thought, shaped the post-Soviet
evaluations of national artistic legacies. It is argued that the political relationship with the totalitarian past, like in
many post-socialist areas where the immediate past was subjected to radical re-evaluation, affected Lithuanian artists’ and
critics’ attitude towards local Soviet art. Because of an obvious lack of underground art in Soviet Lithuania, however, the
retrospective usage of political categories here became problematic. Especially in international representations, the complexities
of artists’ relationship with officialdom came to be routinely assigned to the phenomenon of non-conformism; this eventually
obfuscated the differences between the Lithuanian Soviet art context as somewhat different from the Russian case.

Mindfulness-based Cognitive Therapy (MBCT) is a class-based programme designed for use in the prevention of relapse of major depression. Its aim is to teach participants to disengage from those cognitive processes that may render them vulnerable to future episodes. These same cognitive processes are also known to maintain depression once established, hence a clinical audit was conducted to explore the use of MBCT in patients who were currently actively depressed, and who had not responded fully to standard treatments. The study showed that it was acceptable to these patients and resulted in an improvement in depression scores (pre-post Effect Size=1.04), with a significant proportion of patients returning to normal or near-normal levels of mood. 相似文献
