This study examined the hypothesis that gender differences in eating restraint might mediate previously reported gender differences in cognitive restructuring tasks. Thirty female and 30 male college students matched for dietary restraint were administered two tests that had differentiated females from males and obese from normal-weight individuals in previous research: Luchins' water jar problems, and the Embedded Figures Test. On the water jar problems, use of the initial solution when no longer most efficient was greater for restrained eaters than for unrestrained eaters and no gender differences were found, supporting the hypothesis. On the Embedded Figures Test, males performed better than females, with restrained females tending to perform most poorly.Portions of this paper were presented at the meeting of the Midwestern Psychological Association, Chicago, May 1985. 相似文献

The effects of different arrangements of demonstration and imitation of modeled actions on the learning of the 26 handshapes of the American manual alphabet were investigated. A concurrent group (N =16), which imitated handshapes concurrently with their demonstration, was compared with a delayed group (N = 16), which delayed imitation until 3 handshapes had been displayed, and with a combination group (N = 16), which practiced under a combination of concurrent conditions early in acquisition and delayed conditions later in acquisition. Following acquisition, learning was assessed by means of immediate and long-term recall and recognition tests. The delayed group was superior to the concurrent group in long-term serial recall and in immediate and long-term recognition of 3-letter sequences (in nonserial order); the performance of the combination group was between those of the delayed and concurrent groups. Therefore, delaying imitation in acquisition required subjects to expend more cognitive effort to retain and produce handshapes when requested than did concurrent imitation. This was beneficial to development of task knowledge that could be relied on for postacquisition recall and recognition of handshapes. 相似文献

A quasi-experimental replication of an intervention for promoting tobacco control policies in Northwest Indian tribes is described and the process of intervention including issues of collaboration among research institutions and Indian organizations is discussed. The policy intervention was evaluated using a pretest-posttest design wherein 20 tribes that had served as wait-list controls now received the intervention. The intervention comprised a tribal representative attending a kickoff orientation; follow-up visits to the tribes; distribution of tobacco policy workbooks; and phone call consultations. Policy status and stringency were assessed by means of telephone interviews with two key contacts per tribe, and by a count of enacted policies. There were significant pre-post changes in the primary outcome measure, a composite summary score of tobacco policy stringency, and changes were also reflected in enacted policies. The intervention effects observed were similar to those found in the prior randomized trial and suggest a robust, disseminable intervention. Much of the success achieved was attributed to the role of an Indian organization in planning the project and implementing the intervention and evaluation protocols. 相似文献

This study investigated the relationship between frequency of intrusive thoughts and susceptibility to reminiscent stimuli and consequent distress in parents of children with cancer and parents with healthy children. Cancer-related words embedded in the Stroop task (e.g., “chemo” printed in green ink), served as the reminiscent stimuli. Results indicated that frequency of intrusive thoughts reported 2 months before the experimental session was positively correlated with evoked thoughts and associated distress among parents with ill children. Intrusive thoughts predicted 11–17% of the variance in evoked thoughts and in elicited distress, whereas other symptoms of chronic stress did not predict evoked thoughts and elicited distress. Cognitive and affective task reactivity by parents of children with cancer were not accompanied by behavioral or physiological reactivity. Future research should examine the extent to which more acute and naturalistic intrusive thoughts elicit reactivity across cognitive, affective, behavioral, and physiological dimensions, and long-term physical and mental health effects associated with chronic intrusive thoughts. 相似文献

We investigated potential gender differences in video game (pong) performance in university students. In Experiment 1 men (N = 16) performed significantly better than women (N = 16). Experiment 2 was similar to the first, but used 14 men and 14 women who were matched carefully on previous video game experience. In spite of the matching, results replicated those of the first experiment. In Experiment 3 we evaluated the effect of an audience (male, female, none) on pong performance in 42 men and 42 women. We also assessed trait competition anxiety (Sport Competition Anxiety Test scores), sex role identification (Bem Sex Role Inventory scores), and video game experience. Both genders showed significantly poorer performance when they played pong in the presence of a female audience. Overall, males outperformed females as in the first two experiments. Examination of individuals with low, medium, and high levels of sport competition anxiety and videogame experience reveals persistent gender differences in performance, seemingly independent of levels of anxiety and experience. In all three experiments, both men and women showed significant improvement in performance over trials. 相似文献

The production of the cognitive internal state word know by four 2- to 5-year-old children and their parents was examined. The levels of meaning of cognitive words can be categorized hierarchically along the dimensions of conceptual difficulty and abstractness (see Booth & Hall, 1995). The present study found that children and their parents expressed low levels of meaning less frequently, whereas they expressed high levels of meaning more frequently as a function of age. The children's use of know was also correlated positively with (1) their number of different words produced suggesting that cognitive words are related to more general semantic processes, and (2) with parental use of those same cognitive words suggesting that parental linguistic input may be an important mechanism in cognitive word acquisition. Finally, young children tended to use know more to refer to themselves than to refer to others, whereas their parents tended to use know equally to refer to self and others. The importance of cognitive words in a theory of language acquisition is discussed. 相似文献

Prepubescent boys and girls who had participated for one or more years in a coeducational physical education program were classified by grade (3, 4, and 5) and year (1977, 1978, and 1979). Scores from the AAHPER Youth Fitness Test were analyzed for differences. Results indicated that females at prepubescent ages may be expected to perform at similar levels to boys of the same age on most test items. While differences were not significant, girls in 1979 were actually better than boys of the same age from the two previous years. 相似文献

Authors of almost all learning texts have indicated that unconditional/ stimulus-conditional stimulus (UCS-CS) trials (backward conditioning) utilized in classical conditioning experiments will not result in establishing a conditional response (CR) (excitation). Recently, it has been proposed that backward conditioning can take place although whether UCS-CS trials result in excitation or inhibition has been left unspecified. It is proposed that the diversity of findings can be attributed to inadequate methodology and the use of a classical-instrumental transfer paradigm. When only traditional Pavlovian conditioning studies are examined, the experimental findings suggest that UCS-CS trials will result in inhibition. 相似文献

In two experiments, rats acquired brightness discriminations in a free-operant circular runway with two response alternatives. Both individual and group choice times revealed continuous changes that were not apparent in the discrete measure of choice. Two major assumptions of Spence's discrimination learning theory were confirmed: (a) learning is continuous, and (b) discriminative stimuli in simple discrimination tasks of both simultaneous and successive types are compounds with position elements as well as elements from the relevant visual dimension. The distinctive, consistent pattern of learning revealed by the choice-time measure suggests that position habits reflect a learning strategy in which the complex task is learned as a series of simpler ones. 相似文献
