Stimuli associated with less effort or with shorter delays to reinforcement are generally preferred over those associated with greater effort or longer delays to reinforcement. However, the opposite appears to be true of stimuli thatfollow greater effort or longer delays. In training, a simple simultaneous discrimination followed a single peck to an initial stimulus (S+FR1 S−FR1) and a different simple simultaneous discrimination followed 20 pecks to the initial stimulus (S+FR20 S−FR20). On test trials, pigeons preferred S+FR20 over S+FR1 and S−FR20 over S−FR1. These data support the view that the state of the animal immediately prior to presentation of the discrimination affects the value of the reinforcement that follows it. This contrast effect is analogous to effects that when they occur in humans have been attributed to more complex cognitive and social factors. 相似文献

We reflect on which traditional texts are suitable for the introduction into psychodynamic thinking for bachelor students in the faculty of psychology. We come to the conclusion that the use of works known and individually valued by the students from the world and/or trivial literature are suitable to allow students to carry out fictive preliminary conversations with their heroes from novels or films. 相似文献

The present study aims to further develop the General Ecological Behavior (GEB) scale in order to apply it cross‐culturally. The scale is proposed to be relatively open, neither bound to a particular set of ecological behaviors nor to a particular questionnaire response format. Questionnaire data from 686 California students were compared with the original Swiss calibration data. Reliability, internal consistency, and discriminant validity revcal that the GEB could be applied to the California students as well as to the Swiss sample, which consisted of older adults. Because the GEB measure makes use of behavior difficulties–caused by situational influences‐the proposed approach also guides the search for political actions that could promote changes in more ecologically behaving societies. 相似文献

The goal of this article was to outline issues critical to evaluating the literature on incremental benefit of multiple effective treatments used together, vs. a single effective treatment, for childhood ADHD. These issues include: (1) sequencing and dosage of treatments being combined and compared; (2) difficulty drawing valid conclusions about individual components of treatment when treatment packages are employed; (3) differing results emerging from measurement tools that purportedly measure the same domain; and (4) the resultant difficulty in reaching a summary conclusion when multiple outcome measures yielding conflicting results are used. The implications of these issues for the design and conduct of future studies are discussed, and recommendations are made for future research. 相似文献

A tool that is commonly used to investigate selection among different alternatives in a changing environment is the task-switching
paradigm. Functional neuroimaging has pointed out a role for the posterior medial frontal cortex and the posterior parietal
cortex in the voluntary selection of task sets. In the present study, we set out to investigate the temporal dynamics of these
agency-related processes (in task choice vs. no-choice conditions) using event-related brain potentials (ERPs). The results
revealed agency-related modulations of a series of ERP components, including (1) an early parieto-occipital activation, taken
to reflect the evaluation of choice versus no choice; (2) a subsequent medial frontal expression of the voluntary selection
between task sets; (3) a CNV-like sustained negativity in preparation for the target; (4) a target-induced N210—P210 complex,
taken to reflect early sensory-perceptual processing; and (5) a target-induced P3, associated with the evaluation of the stimulus
and its designated response vis-à-vis the chosen versus competing task sets. Together, these results indicate that the opportunity
to choose between tasks invokes activity originating from the medial frontal cortex, associated with voluntary task set selection,
but also activation at different time points in a number of other brain areas, not necessarily captured by functional neuroimaging. 相似文献

Die Verhaltensmedizin ist das Arbeits- und Forschungsgebiet, in dem empirisch geprüfte Methoden der Verhaltenstherapie in unterschiedlichsten medizinischen Disziplinen eingesetzt werden. Biopsychosoziale Erklärungsansätze für körperliche Gesundheit und Krankheit werden zur Ableitung präventiver, diagnostischer, therapeutischer und rehabilitativer Maßnahmen herangezogen. Dieses interdisziplinäre Arbeitsgebiet ist im Rahmen der psychotherapeutischen Weiterbildung etabliert. In diesem Beitrag wird ein Weiterbildungscurriculum mit den Schwerpunkten Verhaltensmedizin und Kognitive Verhaltenstherapie vorgestellt. 相似文献

Environmental knowledge and conservation behavior: exploring prevalence and structure in a representative sample 总被引:5,自引:0,他引:5

Knowledge is commonly seen as a necessary precondition for a person’s behavior. Consistent with this, most educational interventions rely on knowledge transfer. However, for the most efficient informational strategies for education, it is essential that we identify the types of knowledge that promote behavior effectively and investigate their structure. A questionnaire consisting of three environmental knowledge scales and a conservation behavior measure was sent to 5000 randomly selected Swiss adults. A completed questionnaire was returned by 55% of them (N=2736). A series of structural equation analyses indicates that the three knowledge forms exert different influences on conservation behavior: Action-related knowledge and effectiveness knowledge have a direct effect on performance. In contrast, system knowledge is more remote from behavior, exerting only a mediated influence on it by way of affecting the other two knowledge types. 相似文献

To advise policy‐makers about possible courses of action in the environmental domain, psychological science should employ a support system that allows for evidence‐based decisions with respect to the three generic policy questions: what, where, and how. The key to such a system is a measurement instrument in which environmental motivation becomes tangible in individual actions. In this article, we provide empirical examples of such a decision support system in the environmental domain. It consists of (a) evidence about environmental motivation of persons, (b) evidence about motivation's spatial distribution, (c) knowledge about the socio‐cultural conditions that affect individuals when they translate motivation into action (i.e. structural information), and (d) a forecast of the environmental impact—the concrete conservation potential of various behaviors. Pour conseiller les décideurs à propos de lignes de conduite possibles dans le domaine de l’environnement, la science psychologique devrait utiliser un système qui tienne compte des décisions provenant des trois questions génériques suivantes: quoi, ou et comment? La clé d’un tel système consiste en un instrument de mesure dans lequel la motivation environnementale devient tangible dans les actions individuelles. Dans cet article, nous prenons des exemples empiriques de telles aides à la décision dans le domaine de l’environnement. Peut être ainsi montré a) la motivation environnementale des personnes, b) la distribution spatiale de la motivation, c) l’influence de la connaissance des conditions socioculturelles des individus quand ils transforment motivation en action (i.e. information structurale) et (d) la prévision de l’impact environnemental sur le maintien potentiel de divers comportements. 相似文献
