The importance of work and love for healthy functioning is well documented. This article addresses the relationship between them. The authors argue, based on a psychoanalytic‐existential perspective, that people's choice of work and love is related to similar unresolved childhood issues and that career burnout and couple burnout are related to failure in the existential quest aimed at solving these issues. The existence of a relationship between career burnout and couple burnout is demonstrated by several clinical examples and the results of an exploratory cross‐cultural study involving Israeli, Spanish, Portuguese, American, British, and Finnish students. Implications for career and couple counseling are drawn. 相似文献

Behavior maintained with 2-component concurrent variable interval schedules of reinforcement (CONC VIVI) is described well by the matching law. Deviations from matching behavior have been handled by adding free parameters to the matching law equation. With CONC VIVI schedules there are infinitely many solutions to the matching law equation at each value of the procedural parameters. However, at each value of the procedural parameters, only one combination of durations of intervals spent in each VI component (dwell times) yields the combined maximum reinforcement rate. The equations that yield the optimal dwell times solution for CONC VIVI schedules are mathematically incompatible with the matching law. Optimal performance and matching coincide only when the parameter values of the two VI components are equal. It seems reasonable to use optimal behavior to assess performance in these schedules. Researchers have not compared optimal and empirical performances in CONC VIVI possibly because the equations for optimal dwell times (ODT) can be solved only numerically. We present a table of ODT for a wide range of VIs and changeover delays. We also derive a function m that can be used to compare matching data and the matching behavior predictions of optimization. We prove that 0.5<m<1.003502, and we describe some of the more nteresting properties of the function. 相似文献

We look at two fundamental logical processes, often intertwined in planning and problem solving: inference and update. Inference
is an internal process with which we uncover what is implicit in the information we already have. Update, on the other hand,
is produced by external communication, usually in the form of announcements and in general in the form of observations, giving
us information that might not have been available (even implicitly) before. Both processes have received attention from the
logic community, usually separately. In this work, we develop a logical language that allows us to describe them together.
We present syntax, semantics and a complete axiom system; we discuss similarities and differences with other approaches and
mention how the work can be extended. 相似文献

Previous work demonstrated that there were differences between literate and comparable illiterate adult subjects. These differences were found in the performance on several tests and on patterns of activation on PET and fMRI. In the present study subjects that learned to read and to write in adulthood (being previously completely illiterate) were compared to controls, that is subjects that learned at school at the proper age. Magnetoencephalography was done while subjects were reading words. Results showed that, although the reading performance was the same in both groups while performing the task, the pattern of source distribution was different between groups. There were more late sources in right temporo‐parietal areas of late literates compared to controls and more late sources in left inferior frontal cortex in control subjects. It is concluded that learning to read in adulthood is a process supported by different brain structures from the ones used when learning occurs at the proper age. This may suggest that the same task can be similarly performed by relying on diverse functional brain anatomic networks. 相似文献

AbstractRelaxation techniques have evidence-based support in the research community. However, not all relaxation techniques have the same effectiveness or generate the same states of relaxation. For this reason, indications should be established for each of them. Studies into Self-Applied Relaxation Therapy (SART) show that they can decrease anxiety, stress, blood pressure and craving. This study explores to what extent each SART component is responsible for the results found, which is the most appropriate depending on the target variable to be controlled and whether any of the components are dispensable. Ninety-three university volunteer students participated in the study, aged between 18 and 45; 81.70% were female. Results showed that each of the components had similar efficacy and paradoxical effects on certain participants (8% to 26%). From a clinical perspective, this study concludes that SART can be adapted to the user, and a specific combination of components should be designed for each patient. 相似文献

Previous studies have demonstrated that older adults can use visually distinctive cues to enhance their spatial memory performance
and their recall of the identities of items located in space. Other research has shown that older adults can also use relational
information to enhance recall. The relationship between relational and visuospatial support for memory across the adult lifespan
is complex and has been little explored. In the present study, this relationship was examined in tasks that measured free
recall for item sets possessing different degrees of visuospatial and relational support for recall. It was predicted that
both types of support would enhance older adult recall relative to that of the young, and that the two types of support would
synergize. The results were generally consistent with these predictions. These findings show that older adults can use relatively
simple relational or visuospatial support systems to enhance free recall significantly.

We present new Spanish norms for object familiarity and rated age of acquisition for 140 pictures taken from Snodgrass and Vanderwart (1980), together with data on visual complexity, image agreement, name agreement, word length (in syllables and phonemes), and five measures of word frequency. The pictures were presented to a group of 64 Spanish subjects, and oral naming latencies were recorded. In a multiple regression analysis, age of acquisition, object familiarity, name agreement, word frequency, and word length made significant independent contributions to predicting naming latency. 相似文献

The present study manipulated the number of responses in a modified fixed-interval schedule by imposing a blackout after each unreinforced response during the interval. The blackout duration was varied, and the duration of the fixed interval was held constant. The subjects were initially exposed to a fixed-interval 300-sec schedule. Blackout durations of 0, 10, and 50 sec were used. Following this, a fixed-interval 30-sec schedule was used with blackout durations of 0, 1, and 5 sec. Under the fixed-interval 300-sec schedule, the number of interreinforcement responses varied over a wider range than occurred under the fixed-interval 30-sec schedule. The duration of the postreinforcement pause decreased as blackout durations were increased and number of responses decreased on the fixed-interval 300-sec schedule, but pause length did not vary with changes in blackout duration and number of responses for the fixed-interval 30-sec schedule. The differences in the effects of blackout duration and response manipulation on the two fixed-interval schedules were attributed to relatively greater changes in the number of interreinforcement responses for the fixed-interval 300-sec schedule. 相似文献

Attention deficit hyperactive disorder (ADHD) is associated with elevated levels of substance abuse, but the cognitive linkages
involved have been little explored. The present study builds upon earlier work showing that more gestalt, as opposed to feature-intensive,
styles of processing are conductive to substance abuse, especially in those with ADHD symptoms. The work reported here indicates
that a protective factor against substance abuse may lie in relatively efficient heuristic processing, especially synthetic
or inferential heuristic processing, but further demonstrates that those with ADHD symptoms tend to have poorer abilities
in this regard, even at the subclinical, nondiagnosed level. Results are discussed in terms of the gestalt/featureintensive
processing theory of cognition. 相似文献

Blocking occurs when previous training with a stimulus A reduces (blocks) subsequent learning about a stimulus B, when A and B are trained in compound. The question of whether blocking exists in olfactory conditioning of proboscis extension reflex (PER) in honeybees is under debate. The last published accounts on blocking in honeybees state that blocking occurs when odors A and B are similar (the "similarity hypothesis"). We have tested this hypothesis using four odors (1-octanol, 1-nonanol, eugenol, and limonene) chosen on the basis of their chemical and physiological similarity (experiment 1). We established a generalization matrix that measured perceptual similarity. Bees in the "block group" were first trained with an odor A and, in the second phase, with the mixture AB. Bees in the "novel group" (control group) were first trained with an odor N and, in the second phase, with the mixture AB. After conditioning, bees in both groups were tested for their response to B. We assayed all 24 possible combinations for the four odors standing for A, B, and N. We found blocking in four cases, augmentation in two cases, and no difference in 18 cases; odor similarity could not account for these results. We also repeated the experiments with those six odor combinations that gave rise to the similarity hypothesis (experiment 2: 1-hexanol, 1-octanol, geraniol) and found augmentation in one and no effect in five cases. Thus, blocking is not a consistent phenomenon, nor does it depend on odor similarity. 相似文献
