In two experiments, thirsty rats consumed a compound of sucrose and a non-preferred flavor. In Experiment 1, a conditioned preference was observed in the experimental group when animals were tested both thirsty and hungry, but not when they were tested just thirsty. Animals in the control group, which experienced the flavor and the sucrose unpaired, never showed a preference. Experiment 2 replicated the absence of a preference in the experimental group when rats were tested thirsty, but provided evidence that a flavor-taste association had been formed during training. After conditioning, sucrose was paired with LiCl in group Dev whereas it was unpaired in group NonDev. The sucrose devaluation produced a decrease in CS preference in group Dev, and an increment in group NonDev. Taken together, these results show that preference for a non-preferred flavor can be readily observed after pairings with the positive consequences of the US (calories or absence of an expected illness) rather than with a palatable flavor.  相似文献

This research aims to analyze the relationship between sociocultural values and human food preferences. The latter, as shown in this paper, are greatly influenced by cultural identity. This work stems from a theoretical context that originated in Europe and the United States towards the mid‐twentieth century, within the field of the anthropology of food. A qualitative and quantitative analysis has been performed in the Comunidad Autónoma de Aragón (Spain). Research methods include focus groups, in‐depth interviews, participant observation, and a questionnaire that was handed out to a representative sample of the Aragonese population (816 people over 21 years of age; confidence level of 95.5% and error margin of ±3.5). Regarding the research outcome, a highly significant qualitative and quantitative connection has been found between food selection and cultural identity. In other words, people prefer to consume foods that are symbolically associated with their own culture, in order to reinforce their sense of belonging. Although this study has been carried out in Aragón, it is our belief that the results can be generalized to other areas. The originality and interest of our findings are notable considering that, to date, few works have analyzed the sociocultural factors motivating food behavior. Moreover, these results could be used by public and private organizations to meet objectives such as health promotion and product marketing.  相似文献

In previous studies of rapid elbow movements in young healthy men, characteristic task-dependent changes in the patterns of muscle activation when movement speed or distance was varied have been reported. In the present study, the authors investigated whether age or gender is associated with changes in the patterns of muscle activity previously reported in young men. Arm movements of 10 healthy older and 10 healthy younger participants (5 men and 5 women in each group) were studied. Surface electromyograms (EMGs) from agonist (biceps) and antagonist (triceps) muscles, kinematic and kinetic parameters, as well as anthropometric and strength measures were recorded. All 4 groups of participants showed similar task- (distance or speed) dependent changes in biphasic EMG activity. Similar modulation of the initial rate of rise of the EMG, integrated agonist and antagonist EMG activity, as well as their relative timing were observed in all 4 groups. Those results suggest that older individuals of both genders retain the control strategies for elbow movements used by young individuals. Despite the qualitative similarities in the patterns of muscle activation, the men moved more quickly than the women, and younger participants moved more quickly than older participants. Those performance differences could not be explained in terms of differences in body size and strength alone.  相似文献

The relationship between defense mechanisms and symptoms was assessed in a group of 196 psychiatrically hospitalized adolescents. Defense mechanisms were measured through the use of the Defense Mechanisms inventory (DMI); symptoms and problem behaviors were measured with the Youth Self-Report. Univariate and multivariate analyses indicated that externalizing symptoms are associated with defenses that locate the conflict outside of the self, whereas internalizing symptoms are associated with defenses that locate the conflict within the self. In contrast to previous reports, no gender differences, were found in defense preference, though gender differences were found in the relation of defenses to symptoms. The findings are consistent with clinical theory of defense processes and support the distinction between internalizing/externalizing behaviors and personality dimensions for both symptoms and defenses. The study supports the validity of the adolescent form of the DML.  相似文献

Are there psychoanalytic ideas about what it means to be fully and creatively alive? Thoughts about this are prompted by Winnicott’s account of living by compliance or by creative apperception. A necessary aspect of independent, creative aliveness is a capacity to be interested in what disturbs our usual thought processes. Clinical examples show the truth of this for therapists in the clinical situation and it applies to life in general as well. Being fully alive involves a particular use of memory so as to move actively up and down one’s life experiences between past and present and also the ability to extend this imaginatively into the future, including particularly the experience of one’s own death which is ultimately and inescapably ‘uncanny’. Such freedom of internal movement makes it possible to see the present as a point of encounter between the past and the future. The past is bounded by the primal scene and the future by death, which represent the beginning and end of time. The present is thus also an encounter between time and timelessness. To tell a dream in an analytical session is to bring the timelessness of the unconscious into a time-bound framework. A clinical example shows how a sense of this crossover between time and timelessness helped a patient use his dream experience to develop a greater sense of aliveness. Vermeer’s painting of ‘The Kitchen Maid’ pouring milk is analysed as a visual representation of the intersection of time and timelessness. A case in a clinical seminar is described, which produced a disorienting sense of timelessness in the seminar group. The seminar leader then needed to help the discussion stay poised at a crossing-point between timelessness and time. A discussion of the myth of Orpheus considers Orpheus’ compulsion to look back at Eurydice as a failure of aliveness because he could not dream Eurydice at the intersection between the timelessness of the underworld and the linear temporality of everyday existence.  相似文献

RESUMEN

El trabajo de investigación desarrollado en este artículo representa un intento de extender los principios y técnicas de evaluación conductual a uno de los ámbitos aplicados de la educación especial, la deficiencia mental, ámbito en el que existía una carencia práctica. El objetivo fundamental de esta investigación ha consistido en diseñar un procedimiento que satisfaciera los aspectos de Evaluación, Diagnóstico Conductual y Seguimiento o Evaluación Continua. Se pretendió elaborar un procedimiento: a) que abarque todas y cada una de las áreas o repertorios comportamentales que resultan necesarios para proveer una estimación completa del nivel comportamental de un sujeto con retraso mental, b) que cumpliera con los requisitos psicométricos fundamentales, además de permitir una evaluación continua. Respecto a los objetivos planteados, se consiguió elaborar un sistema conductual de evaluación y diagnóstico del retraso mental que cumplía con los principales requisitos, quedando por estudiar en profundidad la validez de tratamiento del Sistema.  相似文献

ABSTRACT

Over the last 10 years, Web-based surveys have developed a reputation as an easy and economical method of collecting data. However, as with all research methods, there is a need for careful design and planning. This article reviews the literature on the use and effectiveness of Web surveys. It explores the similarities and differences between Web surveys and postal or telephone surveys, the opportunities and limitations of Web surveys, and the use of Web surveys in visitor studies research. Design tips are provided to assist users to make the best possible use of this important new tool.  相似文献

The more replicated findings about gender difference in cognitive performance suggest female superiority on visuomotor speed and language ability and male superiority on mechanical and visuospatial tasks. Generally, group strengths found in the early school years become more established at adolescence and remain stable through adulthood. The current study tested whether the patterns established in the early years remained among 30 adult subjects. We also utilized a series of exploratory analyses to determine if observed gender differences were impacted by the covariance present between all cognitive tests. Results suggest that although the patterns established in the early years remain stable through time for males, the established patterns for females are altered with age. Our findings are compelling in supporting a male advantage on visuospatial tasks among older adults. These findings are discussed in terms of common variance between test instruments as a possible source of difference. Our finding that the gender effect tended to increase when common variance was controlled argues that this methodology may enhance the ability to detect domain specific effects.  相似文献

I attempt to characterize the A-theory of time in such a way as to avoid certain standard objections to it, like those derived from McTaggart's paradox. These objections often arise from conflation of the A-theory with other doctrines which are not entailed by it, but which happen to be held by individual A-theorists. In my view, the A-theory is most defensible when combined with a certain analysis of tense (which I call 'the counterfactual theory of tense'), and with realism about the past and future.  相似文献
