This review considers the origins of the errorless learning (EL) concept, its application in memory rehabilitation, the evidence
for its effectiveness, and the theoretical basis for the observed findings. The evidence suggests that EL offers valuable
benefits for at least some people with memory impairments when teaching certain types of tasks. However, the benefits are
not evident for all groups, some findings are equivocal, and there are some limitations associated with this approach. We
discuss methodological issues impacting on these mixed findings, consider which theoretical explanations might account for
the findings regarding benefits and limitations of EL, and comment on the implications for rehabilitation practitioners of
the current state of evidence in this area. 相似文献

The evolutionary neurological foundations of religious experience are detailed. Human beings have been burying and preparing their dead for the Hereafter for more than 100,000 years. These behaviors and beliefs are related to activation of the amygdala, hippocampus, and temporal lobe, which are responsible for religious, spiritual, and mystical trancelike states, dreaming, astral projection, near-death and out-of-body experiences, and the hallucination of ghosts, demons, angels, and gods. Abraham, Moses, Muhammad, and Jesus Christ, and others who have communed with angels or gods display limbic system hyperactivity, whereas patients report religious hallucinations or out-of-body experiences when limbic structures are stimulated or excessively activated. It is postulated that limbic and temporal lobe structures account for the sexual and violent aspects of religious behavior and also serve as a "transmitter to God," and that the evolution of these structures made spiritual experience possible. 相似文献

Respiration influences heart rate variability, leading to the suggestion that respiration should be controlled to assess autonomic
function by using heart rate variability. Clearly, control of respiration is advantageous or even essential in several experimental
circumstances. However, control of respiration, by itself, produces a small, but significant, increase in mean heart rate
and a decrease in respiratory synchronous variation in heart rate. We tested whether, in some experimental situations, it
may be possible to arrive at similar interpretation about autonomic function with and without using control of respiratory
rate. heart rate spectral powers from nine subjects were compared between spontaneous and metronomic breathing during two
sympatho-excitatory stresses, lower body negative pressure (LBNP) and head up tilt (HUT). The normalized spectral powers in
supine and HUT during spontaneous breathing were: 0.43 and 0.75 in very low (VLF) and 0.28 and 0.09 in high frequency (HF)
regions. The powers during metronomic breathing were: 0.36 and 0.82 (VLF) and 0.36 and 0.09 (HF). The powers in supine and
LBNP during spontaneous breathing were: 0.43 and 0.81 (VLF) and 0.28 and 0.06 (HF). The powers during metronomic breathing
were: 0.36 and 0.80 (VLF) and 0.36 and 0.07 (HF). All p values were <0.05. Therefore, changes in heart rate spectral powers
during HUT and LBNP were similar during metronomic breathing and spontaneous breathing. These results suggest that in experimental
designs such as in our study, using metronomic breathing may not provide any additional insight into autonomic function than
that can be obtained during spontaneous breathing. 相似文献

The use of quantum mechanical concepts in social science is a fairly new phenomenon. This paper uses one of quantum mechanics’ most basic concepts, probability interference, to explain the violation of an important decision theory principle (the ‘sure-thing principle’). We also attempt to introduce other quantum mechanical concepts in relation to the sure-thing principle violation. 相似文献

Most papers using experimental data find that a significant number of agents are not utility function maximizers. Using three experimental datasets, we provide empirical evidence that these violations of utility function maximizing behavior are simply generated by a violation of the preference transitivity axiom. Moreover, we find that 97% of agents’ behavior is consistent with maximization of a generalized utility function called a variable intervals function (which corresponds to a numerical representation of complete-acyclic preferences). 相似文献

A linked perceptual class consists of two distinct perceptual classes, A′ and B′, the members of which have become related to each other. For example, a linked perceptual class might be composed of many pictures of a woman (one perceptual class) and the sounds of that woman's voice (the other perceptual class). In this case, any sound of the woman's voice would occasion the selection of any picture of the woman and vice versa. In addition, after learning to name the woman in the presence of one picture, that name would be uttered when presented with all of the images of the woman's face and all of the sounds of her voice. This study involved 15 participants and sought to (a) maximize the percentage of participants who formed linked perceptual classes, and (b) determine whether those classes acted as transfer networks, that is, whether the discriminative function of one class member would generalize to other members of the class and not to members of a different class. The rate of emergence of each linked perceptual class was maximized by establishing a single class‐linking conditional relation between the clearest member of one class used as a sample stimulus and the most ambiguous member of the other class used as a comparison stimulus. Class formation was demonstrated using the serial and programmed presentation of A′–B′ probes that consisted of untrained pairs of stimuli drawn from the A′ and B′ classes. Most participants showed immediate emergence of the two linked perceptual classes. The remaining participants showed delayed emergence following a second exposure to each originally error‐producing probes. Once the linked perceptual classes had emerged, a differential response to a specific member of one perceptual class generalized mostly or completely to the other members of that linked class and rarely, if ever, to members of the other linked class. Thus, generalization did not depend on the specific class members that had been used for discrimination training. 相似文献

The present study investigates the transfer of aversively conditioned respondent elicitation through equivalence classes, using skin conductance as the measure of conditioning. The first experiment is an attempt to replicate Experiment 1 in Dougher, Augustson, Markham, Greenway, and Wulfert (1994), with different temporal parameters in the aversive conditioning procedure employed. Match‐to‐sample procedures were used to teach 17 participants two 4‐member equivalence classes. Then, one member of one class was paired with electric shock and one member of the other class was presented without shock. The remaining stimuli from each class were presented in transfer tests. Unlike the findings in the original study, transfer of conditioning was not achieved. In Experiment 2, similar procedures were used with 30 participants, although several modifications were introduced (formation of five‐member classes, direct conditioning with several elements of each class, random sequences of stimulus presentation in transfer tests, reversal in aversive conditioning contingencies). More than 80% of participants who had shown differential conditioning also showed the transfer of function effect. Moreover, this effect was replicated within subjects for 3 participants. This is the first demonstration of the transfer of aversive respondent elicitation through stimulus equivalence classes with the presentation of transfer test trials in random order. The latter prevents the possibility that transfer effects are an artefact of transfer test presentation order. 相似文献
