Functional fixedness (FF) consists in focusing on some function of an object while overlooking another necessary for problem
solving. Assuming that FF occurs when too few meanings are assigned to the major problem aspects, it was hypothesized that
widening the scope of meaning would reduce FF, particularly in subjects providing more responses. The task was completing
two electrical circuits. Meaning training consisted in requesting the subjects to provide responses to questions reflecting
11 meaning variables concerning three referents of the task. The subjects were 64 high school girls about 15 years old, only
half of whom got meaning training. The results showed that meaning training reduced FF: the experimental subjects solved the
target task faster, especially if they assigned more direct or indirect function responses to the target referents. Discussion
centered on the effects of specific and nonspecific meaning training on different phases of problem solving.
This study is based partly on the data presented by the first author in partial fulfillment of the requirements for a master’s
degree at the Department of Psychology, Tel Aviv University. 相似文献

Psychometric functions generated by single eleetroeutaneous stimuli yielded a median coefficient of variation ( σ/μ ) of 0.23. These data are consistent with other psychometric data recently reported by us which yielded σ/μ ratios of this size. The data are discussed and related to conflicting data reported in the recent literature indicating coefficients of variation for this mode of stimulation which are only 1/3 as large. Evidence is presented for partial temporal summation (time-intensity reciprocity) for electrocutaneous stimuli ranging from 175 to 610 microseconds. The data are best fitted by the equation I x ta = k, where a is approximately 0.57. This equation and exponent also fit summation data reported by the same authors who report finding steep psychometric functions. Clearly, then, the mechanism responsible for the very limited temporal summation found for eleetrocutaneous stimulation and the mechanism responsible for very steep psychometric functions are not identical. The discussion also includes speculation regarding possible mechanisms and suggestions for research. 相似文献

In order (1) to study the relationship between complexity and preference for slides of the physical environment and (2) to test the hypothesis that the content of slides (in particular, whether nature or urban) will influence preference, independent of the rated complexity, 88 Ss were asked to rate 56 slides, both for preference and for complexity. Based on dimensional analyses, a nature and an urban dimension were identified. Three major results were obtained: (1) Nature scenes were greatly preferred to urban scenes (p < .001). (2) Complexity predicted preference within the nature domain (r = .69) and within the urban domain (r = .78). (3) Complexity did not account for the preference for nature over urban slides; the greatly preferred nature slides were, in fact, judged on the average less complex than the urban slides. The possibility is raised that the domain-specific character of the preference/complexity relationship found in this study may be general; that is, it may not be a special property of environmentally generated arrays. 相似文献

Emotion regulation and psychopathological symptoms of Chinese school‐age children: A person‐centred and multi‐informant approach 下载免费PDF全文
Emotion regulation (ER) is a critical component of children's development. Many previous studies have utilised a single‐assessment method to reflect child ER, which might result in losing important information regarding the unique contribution of each informant. With a person‐centred approach and multi‐informant reports (mother, teacher and child), the current study examined 196 children's (age M = 9.21, SD = 1.10, range = 7–11 years; 51% girls) ER patterns and their associations with psychopathological symptoms in a Chinese sample. A model‐based clustering procedure resulted in 3 ER groups: the poor family ER group (n = 36), poor school ER group (n = 120), and overall good ER group (n = 40). Significant differences were found among ER clusters on teacher‐reported child psychopathological symptoms compared on the levels of withdrawn depression, somatic complain, thought problems and attention problems. No significant differences were found on the mother‐reported psychopathological symptoms. Compared with children in the poor school or poor family ER clusters, children in the overall good ER group demonstrated fewer psychopathological symptoms at school. Our results confirmed the advantage of adopting multi‐informant assessments to fully capture children's emotional profiles and linked these profiles with children's emotional and behavioural functioning at school. 相似文献

The satisfaction of individuals’ psychological needs for autonomy, competence, and relatedness, as conceived from a self-determination theory perspective, is said to be conducive to personal growth and well-being. What has been unexamined is whether psychological need-based experiences, either their satisfaction or frustration, manifests in people’s self-reported dream themes as well as their emotional interpretation of their dreams. A cross-sectional study (N?=?200; M age?=?21.09) focusing on individuals’ recurrent dreams and a three-day diary study (N?=?110; M age?=?25.09) focusing on daily dreams indicated that individuals experiencing psychological need frustration, either more enduringly or on a day-to-day basis, reported more negative dream themes and interpreted their dreams more negatively. The contribution of psychological need satisfaction was more modest, although it related to more positive interpretation of dreams. The discussion focuses on the role of dreams in the processing and integration of psychological need-frustrating experiences. 相似文献

During exam periods university students are at risk for poor sleep. To understand variability in this vulnerability for poor sleep, the role of the satisfaction of the basic psychological needs for autonomy, competence, and relatedness was examined by assessing university students (N?=?121; 78% female; Mage?=?21.69, SD?=?1.39, range 19–25) before, during, and after an exam period. Need-based and sleep-related functioning deteriorated during the exam period and then improved after the exam period. As need satisfaction decreased (i.e., from pre-exam to exam period) sleep quality, sleep quantity and daytime functioning deteriorated, while subsequent increases in need satisfaction (i.e., from exam to the post-exam period) were accompanied by improvements in sleep quality and daytime functioning. These correlated changes in need-based experiences and the sleep-related outcomes were largely accounted for by changes in stress, suggesting that stress may play an explanatory role in these associations. 相似文献
