Escalation of commitment denotes decision makers' increased reinvestment of resources in a losing course of action. Despite the relevance of this topic, little is known about how information is processed in escalation situations, that is, whether decision makers who receive negative outcome feedback on their initial decision search for and/or process information biasedly and whether these biases contribute to escalating commitment. Contrary to a widely cited study by E. J. Conlon and J. M. Parks (1987), in 3 experiments, the authors found that biases do not occur on the level of information search. Neither in a direct replication and extension of the original study with largely increased test power (Experiment 1) nor under methodologically improved conditions (Experiments 2 and 3) did decision makers responsible for failure differ from nonresponsible decision makers with regards to information search, and no selective search for information supporting the initial decision or voting for further reinvestment was observed. However, Experiments 3 and 4 show that the evaluation of the previously sought information is biased among participants who were responsible for initiating the course of action. Mediation analyses show that this evaluation bias in favor of reinvestment partially mediated the responsibility effect on escalation of commitment. 相似文献

The purpose of the study was to analyze the physical activity and the determinants of sedentary behavior in 1,268 Brazilian adolescents (638 girls, 630 boys) between the ages of 15 and 18 years, randomly selected from a relatively underdeveloped region. Data were collected from a community-based survey in the city of Jo?o Pessoa, Paraiba, Brazil. Information related to physical activity was derived on the short version of the International Physical Activity Questionnaire. The prevalence of sedentary behavior was 28.2% for girls and 19.1% for boys, whilst 28.9% of the girls and 36.7% of the boys showed high physical activity. The sedentary behavior varied by sociodemographic and environmental determinants studied. Parents' education, socioeconomic status, school's characteristics, transport to school, paid work, smoking, alcohol use, and BMI scores were significantly related to sedentary behavior for boys and girls. 相似文献

Attachment-related strategies are thought to be critical for regulation and processing of emotional information. This study examined biases in selective attention to emotional stimuli as a function of insecure attachment. Participants searched for a single target image preceded by to-be-ignored distracters depicting emotional images varying in valence and arousal. Results revealed that, in general, negative distracters affected accuracy levels, and that the anxious attached participants showed a clear interference of the emotional distracters. In contrast, the avoidant group evinced a higher control on such interference. In addition, arousal ratings to distracter images indicated superior emotional activation only for anxious attached participants. Consistent with the evolutionary-based attachment theory threat-related stimuli prompted priority attentional responses. Present findings are in line with evidence showing the deployment of distinct strategies in insecurely attached individuals for the regulation of attention to emotional information. 相似文献

Operant response rate changes within the course of a typical free-operant experimental session. These changes are orderly, and reliably demonstrated with subjects from different species, responding under different experimental conditions. Killeen (1995) postulated that the response rate changes are a function of the interplay between arousal and satiation and offered a mathematical model for this hypothesis. Here we analyze Killeen's model, demonstrating that, although solid in its principles, it presents some flaws in its implementation. Then, based on the same principles, we build and test a new model of within-session motivation dynamics. We also demonstrate that, by representing arousal as a variable that ranges between 0 and 1, we can obtain a surprisingly simple model of free-operant response rate. 相似文献

Husserl left many unpublished drafts explaining (or trying to) his views on spatial representation and geometry, such as,
particularly, those collected in the second part of Studien zur Arithmetik und Geometrie (Hua XXI), but no completely articulate work on the subject. In this paper, I put forward an interpretation of what those
views might have been. Husserl, I claim, distinguished among different conceptions of space, the space of perception (constituted
from sensorial data by intentionally motivated psychic functions), that of physical geometry (or idealized perceptual space),
the space of the mathematical science of physical nature (in which science, not only raw perception has a word) and the abstract
spaces of mathematics (free creations of the mathematical mind), each of them with its peculiar geometrical structure. Perceptual
space is proto-Euclidean and the space of physical geometry Euclidean, but mathematical physics, Husserl allowed, may find
it convenient to represent physical space with a non-Euclidean structure. Mathematical spaces, on their turn, can be endowed,
he thinks, with any geometry mathematicians may find interesting. Many other related questions are addressed here, in particular
those concerning the a priori or a posteriori character of the many geometric features of perceptual space (bearing in mind
that there are at least two different notions of a priori in Husserl, which we may call the conceptual and the transcendental
a priori). I conclude with an overview of Weyl’s ideas on the matter, since his philosophical conceptions are often traceable
back to his former master, Husserl. 相似文献

ABSTRACT We examined the effect of a semantic orienting task during encoding on free recall and recognition of simple line drawings and matching words in middle-aged (44-59 years), older (60-89 years), and oldest-old (90+ years) adults. Participants studied line drawings and matching words presented in blocked order. Half of the participants were given a semantic orienting task and the other half received standard intentional learning instructions. Results confirmed that the pictorial superiority effect was greater in magnitude following semantic encoding compared to the control condition. Analyses of clustering in free recall revealed that oldest-old adults' encoding and retrieval strategies were generally similar to the two younger groups. Self-reported strategy use was less frequent among the oldest-old adults. These data strongly suggest that semantic elaboration is an effective compensatory mechanism underlying preserved episodic memory performance that persists well into the ninth decade of life. 相似文献

The main aim of this research is to study the patterns of narrative change in a case of life design counseling (LDC). The innovative moments coding system (IMCS) was used to conduct an intensive analysis of the career counseling sessions. This coding system is grounded in a narrative conception of the self, and suggests that narrative change results from the elaboration and development of narrative exceptions to a client's core problematic self-narrative. The results supports the adequacy of the IMCS to the study of change in career counseling and reveal that the intervention promotes a pattern of change characterized by three types of innovative moments: action, reflection, and protest. The results are discussed taking into account their implications for career counseling theory, research and practice. 相似文献

The effect of color on the production of responses to the Rorschach task has been considered by investigators from 2 different positions: (a) that color has little effect on the production of responses, and (b) that color increases the number of responses. Some previous results found by the current investigators have supported the first position for the last 3 fully colored Rorschach cards (VIII, IX, and X), in children from 5 to 12 years old. Other studies of ours, however, have confirmed the second position for these same cards with a group of young adults 17 to 23 years old. As there was no increase of responses up to age 12, for this study we hypothesized a developmental effect in adolescence such that there would be an increase in the production of responses to the colored Rorschach cards at the age of 15 to 16 years, and this is what the results indicate. From a pragmatic standpoint, these results imply a revision of interpretive meaning for the Color and Affective Ratio variables in children's protocols. Our results also indicate that color cannot be regarded as a means of expression of affect at age 11 to 12 like it will be from age 15 to 16 and on. 相似文献
