Animal trainers working in scent detection programs are responsible for arranging training contingencies as well as for observing and recording animal behavior. We provided behavioral skills training (BST) to animal trainers working with scent detection rats to improve the treatment integrity of scent‐detection research sessions. We evaluated the trainers' behavior at baseline and during the sequential introduction of each component of BST (instructions, modeling, and feedback). We observed incremental improvements in treatment integrity with the introduction of each BST component. Posttraining probes revealed that these improvements were sustained at least 3 weeks post‐BST. As the trainers' behavior was modified during BST, we observed decrements in measures of rat performance. We discuss the nature of these interactions and their implications for the use of BST in scent detection research and in situations in which intervention with one party produces concomitant effects on the behavior of another. 相似文献

According to objectification theory (Fredrickson & Roberts, 1997), being treated as an object leads women to engage in self‐objectification, which in turn increases body surveillance and body shame as well as impairs mental health. However, very little is known about what factors could act as buffers against the detrimental consequences of self‐objectification. This paper seeks to understand the role of self‐compassion (the ability to kindly accept oneself or show self‐directed kindness while suffering) in the perception that women have of their own bodies. Results indicate that self‐compassion moderated the effect of body surveillance on depression and happiness separately among women. More specifically, for women low in self‐compassion, body surveillance was negatively associated with happiness, which was explained by increased depression. In sum, our results indicate that self‐compassion protects against the detrimental consequences of body surveillance. 相似文献

Ratings for age of acquisition (AoA) and subjective frequency were collected for the 1,493 monosyllabic French words that
were most known to French students. AoA ratings were collected by asking participants to estimate in years the age at which
they learned each word. Subjective frequency ratings were collected on a 7-point scale, ranging from never encountered to encountered several times daily. The results were analyzed to address the relationship between AoA and subjective frequency ratings with other psycholinguistic
variables (objective frequency, imageability, number of letters, and number of orthographic neighbors). The results showed
high reliability ratings with other databases. Supplementary materials for this study may be downloaded from the Psychonomic

This study provides new evidence of motives of secondary social sharing of emotions. In a retrospective study, 140 female (Mage = 29.4 yr., SD=12.8) and 116 male (M = 29.5 yr., SD = 13.1) participants were asked to recall a recent situation in which they had talked to a third person about a positive or negative, low or high intensity emotional narrative they had heard. 70% of the respondents reported having secondarily shared the reported event rapidly after the narration with several persons and at several times. Moreover, they not only described the event, the speaker's reaction and their own reactions, but also revealed the identity of their first confidant. Participants reported having spread the emotional narrative more widely in the high negative condition in order to seek emotional support and social comparison. 相似文献

It is shown that restricted solvability need not be required to hold w.r.t. every component for deriving the existence of additive utilities: additive representations can be shown to exist even when restricted solvability holds w.r.t. only two components. In such cases, the uniqueness property of these representations departs from the classical theory in that it is between ordinal and cardinal. 相似文献

We previously showed that 24 h after learning, mice significantly remembered the first (D1) but not the second (D2) discrimination in a serial spatial task and that an acute stress delivered 5 min before the test phase reversed this memory retrieval pattern.A first experiment evaluated the effects of dorsal hippocampus (HPC) or prefrontal cortex (PFC) lesions, these two brain areas being well-known for their involvement in serial and spatial memory processes. For this purpose, six independent groups of mice were used: non-lesioned (controls), PFC or HPC-lesioned animals, submitted or not to an acute stress (electric footshocks; 0.9 mA). Results show that (i) non-stressed controls as well as PFC-lesioned mice (stressed or not) remembered D1 but not D2; (ii) stressed controls and HPC-lesioned mice (stressed or not) remembered D2 but not D1; (iii) stress significantly increased plasma corticosterone in controls and PFC-lesioned mice, but not in HPC-lesioned mice which already showed a significant plasma corticosterone increase in non-stressed condition.Since data from this first experiment showed that stress inhibited the hippocampal-dependent D1 memory retrieval, a second experiment evaluated the behavioral effect of intrahippocampal corticosterone injection in non-stressed mice. Results show that intrahippocampal corticosterone injection induced a reversal of serial memory retrieval pattern similar to that induced by acute stress.Overall, our study shows that (i) in non-stress condition, the emergence of D1 is HPC-dependent; (ii) in stress condition, the emergence of D2 requires the PFC integrity; moreover, intrahippocampal corticosterone injection mimicked the effects of stress in the CSD task. 相似文献

Contribution of ankle, knee, and hip joints to the perception threshold for support surface rotation

The purpose of the present experiment was to investigate the extent to which subjects can perceive, at very slow velocities, an angular rotation of the support surface about the medio-lateral axis of the ankle, knee, hip, or neck joint when visual cues are not available. Subjects were passively displaced on a slowly rotating platform at .01, .03, and .05 deg/sec. The subjects’ task was to detect movements of the platform in four different postural conditions allowing body oscillations about the ankle, knee, hip, or neck joint. In Experiment 1, subjects had to detect backward and forward rotation (pitching). In Experiment 2, they had to detect left and right rotations of the platform (rolling). In Experiment 3, subjects had to detect both backward/forward and left/right rotations of the platform, with the body fixed and the head either fixed or free to move. Overall, when the body was free to oscillate about the ankle, knee, or hip joints, a similar threshold for movement perception was observed. This threshold was lower for rolling than for pitching. Interestingly, in these postural conditions, an unconscious compensation in the direction opposite to the platform rotation was observed on most trials. The threshold for movement perception was much higher when the head was the only segment free to oscillate about the neck joint. These results suggest that, in static conditions, the otoliths are poor detectors of the direction of gravity forces. They also suggest that accurate perception of body orientation is improved when proprioceptive information can be dynamically integrated. 相似文献

Reexamining the word length effect in visual word recognition: New evidence from the English Lexicon Project 总被引:1,自引:0,他引:1
In the present study, we reexamined the effect of word length (number of letters in a word) on lexical decision. Using the
English Lexicon Project, which is based on a large data set of over 40,481 words (Balota et al., 2002), we performed simultaneous
multiple regression analyses on a selection of 33,006 English words (ranging from 3 to 13 letters in length). Our analyses
revealed an unexpected pattern of results taking the form of a U-shaped curve. The effect of number of letters was facilitatory
for words of 3–5 letters, null for words of 5–8 letters, and inhibitory for words of 8–13 letters. We also showed that printed
frequency, number of syllables, and number of orthographic neighbors all made independent contributions. The length effects
were replicated in a new analysis of a subset of 3,833 monomorphemic nouns (ranging from 3 to 10 letters), and also in another
analysis based on 12,987 bisyllabic items (ranging from 3 to 9 letters). These effects were independent of printed frequency,
number of syllables, and number of orthographic neighbors. Furthermore, we also observed robust linear inhibitory effects
of number of syllables. Implications for models of visual word recognition are discussed. 相似文献

Shame is considered a social emotion with action tendencies that elicit socially beneficial behavior. Yet, unlike other social emotions, prior experimental studies do not indicate that incidental shame boosts prosocial behavior. Based on the affect as information theory, we hypothesize that incidental feelings of shame can increase cooperation, but only for self-interested individuals, and only in a context where shame is relevant with regards to its action tendency. To test this hypothesis, cooperation levels are compared between a simultaneous prisoner's dilemma (where “defect” may result from multiple motives) and a sequential prisoner's dilemma (where “second player defect” is the result of intentional greediness). As hypothesized, shame positively affected proselfs in a sequential prisoner's dilemma. Hence ashamed proselfs become inclined to cooperate when they believe they have no way to hide their greediness, and not necessarily because they want to make up for earlier wrong-doing. 相似文献
