This study examined a gratitude intervention repeating Emmons and McCullough study (2003) in a Spanish sample, Participants were randomly assigned to one of three conditions (gratitude, hassles and any event) and kept daily records during 2 weeks of gratitude, affect, quality of relationships, physical and subjective well-being. We added design features to assess the intervention long-term impact (follow-up measures), and to improve the design control (pre-treatment measures). Following the cited authors' analysis, i.e., comparing groups only in the post-test, we replicated their results, finding differences in positive affect and gratitude between the gratitude condition and the hassles condition. However, when including both the pre and the follow-up measures in the analysis, results were replicated only partially, as the difference in gratitude disappeared. Moreover, the difference in positive affect between groups in the post-test seemed to be influenced mainly by a decrease in positive affect in the hassles group. Post-test differences between groups in positive affect disappeared in the follow-up. Gratitude interventions may have an effect on well-being, but we consider other methods to promote gratitude besides gratitude journals should be tested. 相似文献

A course in professional ethics for civil engineers was taught for the first time in Spain during the academic year 2007/08.
In this paper a survey on the satisfaction and expectation of the course is presented. Surprisingly the students sought moral
and ethical principles for their own ordinary lives as well as for their profession. Students were concerned about the law,
but in their actions they were more concerned with their conscience, aware that it can be separate from the law. 相似文献

A decline in the frequency or intensity of a conditioned behavior following the withdrawal of the reinforcement is called
experimental extinction. However, the experimental manipulation necessary to trigger memory reconsolidation or extinction
is to expose the animal to the conditioned stimulus in the absence of reinforcement. Recovery protocols were used to reveal
which of these two processes was developed. By using the crab contextual memory model (a visual danger stimulus associated
with the training context), we investigated the dynamics of extinction memory in Chasmagnathus. Here, we reveal the presence of three recovery protocols that restore the original memory: the old memory comes back 4 days
after the extinction training, or when a weak training is administered later, or once the VDS is presented in a novel context
24 h after the extinction session. Another objective was to evaluate whether the administration of multi-trial extinction
training could trigger an extinction memory in Chasmagnathus. The results evince that the extinction memory appears only when the total re-exposure time is around 90 min independently
of the number of trials employed to accumulate it. Thus, it is feasible that the mechanisms described for the case of the
extinction memory acquired through a single training trial are valid for multi-trial extinction protocols. Finally, these
results are in agreement with those reports obtained with models phylogenetically far apart from the crab. Behind this attempt
is the idea that in the domain of studies on memory, some principles of behavior organization and basic mechanisms have universal
validity. 相似文献

Animal innovations have far-reaching ecological and evolutionary consequences. The occurrence and persistence of an innovation
require several processes, including exploration, social and asocial learning, and low neophobia. In addition, the identity
of the innovator may determine how these new behaviours are socially transmitted. Taking into account inter-individual and
age differences, we investigated three correlates of animal innovation: object exploration, neophobia level and novel problem-solving
ability in an opportunistic generalist raptor, the Chimango Caracara (Milvago chimango). Eighteen individuals (7 adults and 11 juveniles) were caught during the non-breeding period and housed in individual cages
in outdoor aviaries. Each bird was given three tests: exploration, neophobia and problem-solving. Individuals differed in
their response to novel situations both within and between age groups. Most of the juveniles were more explorative and had
a lower neophobic response to a strange object than adult birds, but both age groups were able to solve a novel problem when
given a food reward. In juveniles, neophobia level and problem-solving performance were inversely related; however, we found
no relationship between these behaviours in adults. Exploration did not correlate with neophobia or problem-solving ability
for either age group. This research is one of the few studies exploring the inter-individual and age differences in behavioural
innovation and their correlates in a bird of prey. The explorative tendency, low neophobia and ability to innovate showed
by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological
success. 相似文献

Affective pictures drive the activity of brain networks and impact behavior. We showed previously that viewing unpleasant
pictures interfered in the performance of a basic nonemotional visual detection task. In the present study, we employed functional
magnetic resonance imaging to test the hypothesis that behavioral interference may result from the interaction between negatively
valenced and motor-related signals in the brain. As in our previous study (Pereira et al., 2006), participants performed a
simple target detection task that followed the presentation of unpleasant or neutral pictures. Our results revealed that an
unpleasant emotional context modulated evoked responses in several regions engaged by the simple target detection task. In
particular, the midcingulate cortex was recruited when participants performed target detection trials during the unpleasant
context, and signal responses in this region closely mirrored the pattern of behavioral interference (as revealed via reaction
time). Our findings suggest that the midcingulate cortex may be an important site for the interaction between negatively valenced
signals and motor signals in the brain and that it may be involved in the implementation of defensive responses, such as freezing. 相似文献

This study reports on outcomes from a behavioral obesity treatment program, evaluating if treatment-related changes in body image and psychological well-being are predictors of weight change during treatment and after follow-up. Participants were 142 overweight/obese women (BMI = 30.2 ± 3.7 kg/m2; age = 38.3 ± 5.8 years) participants in a behavioral treatment program consisting of a 4-month treatment period and a 12-month follow-up. Psychosocial variables improved during treatment and these changes were correlated with 4-month weight reduction. Short-term changes in body size dissatisfaction (p = .002) and mood (p = .003) predicted long-term weight loss. Additional results suggest that there might be a predictive role of short-term changes in body size dissatisfaction and self-esteem on long-term weight loss after accounting for initial weight change (p < .028). We conclude that, along with weight changes, cognitive and affect-related processes influenced during obesity treatment may be related long-term success, in some cases independently of initial weight loss. 相似文献

It would be possible to be affirmed that the most of the educational goals that modernity assumes, they settled down from
the Renaissance. The postmodern age, in its critic to the modern period, demands the recovery of some losses. At the time
of fast changes as it happens in the Renaissance, the Humanism originates a fruitful debate. According to the authors protagonists,
the controversy became a dialogue plenty of common questions to which we find in the contemporary discussion. The reflection
on the thought of one of the most representative and well-known authors, Comenio, it serves to think on the encounter of traditions
in Philosophy of Education. He is a thinker who supplies the basis for his educational practice on a Philosophy of education
and projects a reform to confront some problems that in the essential are repeated today.

According to an increasing number of authors, the best, if not the only, argument in favour of physicalism is the so‐called ‘overdetermination argument’. This argument, if sound, establishes that all the entities that enter into causal interactions with the physical world are physical. One key premise in the overdetermination argument is the principle of the causal closure of the physical world, said to be supported by contemporary physics. In this paper, I examine various ways in which physics may support the principle, either as a methodological guide or as depending on some other laws and principles of physics. 相似文献

Personality tests often consist of a set of dichotomous or Likert items. These response formats are known to be susceptible
to an agreeing-response bias called acquiescence. The common assumption in balanced scales is that the sum of appropriately
reversed responses should be reasonably free of acquiescence. However, inter-item correlation (or covariance) matrices can
still be affected by the presence of variance due to acquiescence. To analyse these correlation matrices, we propose a method
that is based on an unrestricted factor analysis and can be applied to multidimensional scales. This method obtains a factor
solution in which acquiescence response variance is isolated in an independent factor. It is therefore possible, without the
potentially confounding effect of acquiescence, to: (a) examine the dominant factors related to content latent variables;
and (b) estimate participants’ factor scores on content latent variables. This method, which is illustrated by two empirical
data examples, has proved to be useful for improving the simplicity of the factor structure.

Background/Objective: Cancer and its treatment can have a detrimental impact on psychological well-being. Acceptance as the basis of acceptance and commitment therapy (ACT) has shown beneficial effects on depression and anxiety. However, its relationship to fatigue and cognitive impairment has not been investigated. A protective effect of acceptance may open up a new target for psychological intervention.Method: A cross-sectional postal survey was undertaken. 922 hematological cancer survivors (≥ 2.5 years post diagnosis) were recruited through two regional cancer registries in Germany. Acceptance (AAQ-II), fatigue (BFI) and subjective cognitive impairment (AFI) were assessed.Results: Higher levels of acceptance were negatively associated with fatigue and subjective cognitive impairment (R2= .34 and R2= .26, respectively). The relationship between fatigue and fatigue-related impairment of daily life was weaker for survivors with high acceptance.Conclusions: Acceptance is strongly associated with fatigue and subjective cognitive impairment. ACT may be useful to reduce symptoms of fatigue and subjective cognitive impairment in cancer survivors. 相似文献
