A multiple baseline across settings was used to evaluate the effects of differential reinforcement of alternative behavior, nonremoval of the fork ( Hoch, Babbitt, Coe, Krell, & Hackbert, 1994 ), and stimulus fading on consumption of food rejected previously. The study was conducted in two separate settings, and caregivers were trained in the intervention technique to increase generalization to natural settings. Food variety increased in both settings. 相似文献

In January of 2007, freezing temperatures destroyed citrus and vegetable crops in California. By May 2007, more than 9,000 freeze‐related unemployment applications had been filed. Through face‐to‐face interviews, this study documents the experience of 63 farmworkers to find out how they survived the freeze and accessed services. Findings revealed that more than half of the interviewees did not seek benefits from the governmental One‐Stop centers set up to help them. Less than 10% of interviewees stated the benefits had covered their needs. Creating simple, nonbureaucratic guidelines for assisting affected individuals emerged as a need. 相似文献

The goal of the present paper was to demonstrate the influence of general evaluations and stereotype associations on emotion recognition. Earlier research has shown that evaluative connotations between social category members and emotional expression predict whether recognition of positive or negative emotional expressions will be facilitated (e.g. Hugenberg, 2005). In the current paper we tested the hypothesis that stereotype associations influence emotion recognition processes, especially when the difference between valences of emotional expressions does not come into play. In line with this notion, when participants in the present two studies were asked to classify positive versus negative emotional expressions (i.e. happy versus anger, or happy versus sadness), valence congruency effects were found. Importantly, however, in a comparative context without differences in valence in which participants were asked to classify two distinct negative emotions (i.e. anger versus sadness) we found that recognition facilitation occurred for stereotypically associated discrete emotional expressions. With this, the current results indicate that a distinction between general evaluative and cognitive routes can be made in emotion recognition processes. 相似文献

Roy Sorensen has argued that a certain technical use of quotation marks to name the empty string supports a revised version
of Davidson’s theory of quotation. I point out that Sorensen’s considerations provide no support for Davidson’s original theory,
and I show that at best they support the revised Davidsonian theory only to the same extent that they support a simpler revised
version of a Tarskian theory. 相似文献

Heuristics and cognitive biases can occur in reasoning and decision making. Some of them are very common in gamblers (illusion of control, representativeness, availability, etc.). Structural characteristics and functioning of games of chance favor the appearance of these biases. Two experiments were conducted with nonpathological gamblers. The first experiment was a game of dice with wagers. In the second experiment, the participants played two bingo games. Specific rules of the games favored the appearance of cognitive bias (illusion of control) and heuristics (representativeness and availability) and influence on the bets. Results and implications for gambling are discussed. 相似文献

Daniel Ellsberg presented in Ellsberg (The Quarterly Journal of Economics 75:643–669, 1961) various examples questioning the
thesis that decision making under uncertainty can be reduced to decision making under risk. These examples constitute one
of the main challenges to the received view on the foundations of decision theory offered by Leonard Savage in Savage (1972).
Craig Fox and Amos Tversky have, nevertheless, offered an indirect defense of Savage. They provided in Fox and Tversky (1995)
an explanation of Ellsberg’s two-color problem in terms of a psychological effect: ambiguity aversion. The ‘comparative ignorance’ hypothesis articulates how this effect works and explains why it is important to an understanding
of the typical pattern of responses associated with Ellsberg’s two-color problem. In the first part of this article we challenge
Fox and Tversky’s explanation. We present first an experiment that extends Ellsberg’s two-color problem where certain predictions
of the comparative ignorance hypothesis are not confirmed. In addition the hypothesis seems unable to explain how the subjects
resolve trade-offs between security and expected pay-off when vagueness is present. Ellsberg offered an explanation of the
typical behavior elicited by his examples in terms of these trade-offs and in section three we offer a model of Ellsberg’s
trade-offs. The model takes seriously the role of imprecise probabilities in explaining Ellsberg’s phenomenon. The so-called
three-color problem was also considered in Fox and Tversky (1995). We argue that Fox and Tversky’s analysis of this case breaks
a symmetry with their analysis of the two-color problem. We propose a unified treatment of both problems and we present a
experiment that confirms our hypothesis. 相似文献

Internal sets and the Boolean algebras of the collection of the internal sets are of central importance in non-standard analysis.
Boolean algebras are the algebraization of propositional logic while the logic applied in non-standard analysis (in non-standard
stochastics) is the first order or the higher order logic (type theory). We present here a first order logic algebraization
for the collection of internal sets rather than the Boolean one. Further, we define an unusual probability on this algebraization. 相似文献

The principal aim of this study is to determine why police officers are generally found to be more prejudiced towards disadvantaged groups than are the standard population. Two independent processes were expected to account for this effect: Selection and group socialisation. Using a cross‐sectional design (N = 170), firstly, we compared, newly recruited police officers with a control population (selection effect), and secondly, police officers with 1 year of training with the newly recruited ones (group socialisation effect). Results reveal a significant effect of both selection and group socialisation, the two being underlined by distinct processes; right‐wing authoritarianism (RWA) in the case of the former and internalisation of a prejudice norm in the case of the latter. Finally, the results show that group identification moderates the change in internalisation of the prejudice norm. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

The metallic glass Pd40Cu30Ni10P20 in as-cast or pre-annealed states was shot-peened successively at room temperature or at 77 K. The structural state of the glass was characterized by the relaxation spectrum measured in a differential scanning calorimeter. Mechanically induced relaxation of the as-cast glass and mechanically induced rejuvenation of pre-annealed samples are both more evident at 77 K than at 298 K, enabling deductions about the underlying mechanisms. The relaxation spectrum of the glass as a function of temperature displays two broad maxima, which occurring at the higher temperature is attributed to the part of the free-volume distribution associated with flow defects. In samples shot-peened at 77 K, the stored energy after deformation can be as high as 20% of the cold work. Shot-peening simultaneously generates flow defects within shear bands and destroys them in the matrix between bands: whose effect dominates is principally dependent on the initial state of relaxation of the glass. Shot-peening of partially crystallized samples appears capable of breaking up and dispersing crystallites without inducing any further significant crystallization. 相似文献
