We analyzed family dynamics and coping behaviors of parents with a child with an autistic spectrum disorder. Previous research
suggests that moderate levels of cohesion and adaptability are associated with higher levels of positive coping, and that
the more coping strategies a family implements, the greater their satisfaction with family functioning. Using a family systems
approach, the relationships among the familial variables of cohesion, adaptability, and social support were evaluated for
their contributions to coping in the family unit. We also compared the responses of mothers and fathers. Surprisingly, for
these parents of children with autism, those who rated their family as enmeshed implemented more positive coping strategies
than did those from other cohesion styles. This finding suggests that the enmeshed style may be more adaptive for a family
that encounters extreme challenges. Notably, mothers and fathers agreed on all variables except for perception of social support
from family and friends. Mothers perceived more social support from family and friends. The results lead to several interesting
suggestions for future research. 相似文献

Standardized sets of films have been shown to be effective for eliciting emotional states in adults, but no comparable validated stimuli are available for children. We therefore examined the effects of three pre-selected film clips each of 3-min duration in eliciting a pleasant, neutral and unpleasant emotional state in 297 children aged between 6 and 12 years. After the films were presented on a video projector, affective ratings were obtained with the Self-Assessment-Manikin on the emotional dimensions of valence and arousal. Increasing pleasure ratings were observed from the unpleasant to the neutral to the pleasant film. Associated arousal ratings were stronger for the unpleasant and pleasant films compared to the neutral film. Overall, results showed successful elicitation of targeted emotional states only marginally influenced by age, gender or prior experience with the films. The use of these films is therefore suggested for future studies on emotions in children. 相似文献

The present study developed word lists describing three categories of body build—fat, thin, and muscular— for
use in investigating cognitive risk factors for body dissatisfaction. Fifty-one men and 51 women rated the categorization,
valence, and familiarity of 284 body-related adjectives in order to develop the final lists. The normative frequency of each
of the 284 words was determined using an index of American English. The final 19- to 26-item word lists were constructed so
that the average number of syllables, word length, word frequency, and mean percentage of categorization agreement were comparable.
The availability of these word lists will facilitate future cognitive research into a key risk factor for eating disorders. 相似文献

Stiles-Davis proposes that the infants in our experiments (Hofsten & Spelke, 1985) did not reach for perceived objects in order to manipulate them, but rather touched perceived surfaces in order to explore their boundaries. Her commentary raises questions about infants' perception of the boundaries, the unity, and the manipulability of objects. More deeply, it raises the question of what an object is for an infant. We consider each of these questions in turn, in light of our own findings and those of other studies of object-directed reaching, object perception, and the object concept. We suggest that young infants organize the visual world into entities that are bounded, unitary, and manipulable and that infants endow those entities with the core properties of physical objects. 相似文献

Summary Three experiments were conducted to investigate dual-code theory and the levels-of-processing approach in discourse processing. Three concrete and three abstract tests were constructed to be equivalent in the degree to which they were perceived as concrete vs. abstract. All experiments presented concrete and abstract texts under three orienting tasks. Results of the first experiment showed main effects for both text concreteness and orienting tasks and an interaction that can be described by the lack of a difference between the recall rates for the concrete and the abstract texts under the intentional-learning condition. In the second experiment, longer texts were used and a second trial was introduced. The interaction was not replicated. There were main effects for concreteness, orienting tasks, and trials. The third experiment replicated Experiment 2 with subjects in their late 40s and over 70. Main effects were obtained as before. Age interacted with both orienting task and concreteness, indicating that older adults gain less than middle-aged adults from intentional-learning instructions and benefit less from highly concrete texts. The discussion focuses on the relation of Materials and Subjects as factors to dual-code theory and levels of processing approach. 相似文献

The role of binocular vision in a ball-catching task involving spatial uncertainty was examined in three experiments. In all three experiments, subjects' catching performance was evaluated during monocular and binocular viewing, in normal room lighting and in complete darkness with a luminescent ball. Subjects' performance was found to be significantly better with binocular than with monocular vision, especially under normal lighting conditions. In the second and third experiments, catching performance was evaluated in the presence of minimal visual frames, consisting of a series of light-emitting diodes (LEDs). In Experiment 2, the visual frame consisted of a single plane of LEDs, whereas in Experiment 3, the visual frame consisted of two planes of LEDs. Catching performance was found to be significantly better with the visual frame than in complete darkness, but this was true only for binocular viewing. This result supports the hypothesis that binocular convergence is used to scale perceived space and that this information enables subjects to contact the ball successfully. It was further found that postural sway varied between lighting conditions and that less sway was accompanied by higher performance. There was no effect of binocular viewing in this respect. In general, the results suggest two additive effects of viewing conditions: a direct effect of binocular vision on ball catching and an indirect effect of lighting on postural stability, which, in turn, affects catching performance. 相似文献

Syracuse high- and low-avoidance Long-Evans rats (Rattus norvegicus; SHA/Bru and SLA/Bru) were selectively bred for good and poor active-avoidance learning. However, SLA/Bru animals are superior to SHA/Bru rats in conditioned suppression and passive avoidance learning. In this experiment, saccharin taste and almond odor were the components of a compound conditioned stimulus (flavor) in an illness-induced aversive conditioning paradigm. SLA/Bru rats (n = 17) showed stronger conditioned flavor, taste, and odor aversion than did SHA/Bru animals (n = 18). Unselected Long-Evans rats (n = 18) were intermediate between the selected strains. SLA/Bru and Long-Evans rats showed taste-potentiated odor aversions in this experiment, whereas SHA/Bru animals did not. The results provide evidence that genetic factors, as exemplified by the different strains, are importantly involved in the mechanisms underlying interoceptive and exteroceptive aversive conditioning. 相似文献
