We compared the effects of two antecedent strategies commonly used in early childhood settings to increase compliance during activity transitions: a warning condition, in which children were informed of the transition 2 min before it began, and a condition in which children were allowed access to a toy during the transition. Both antecedent interventions were ineffective when implemented alone; however, when these strategies were combined with extinction, improvements in compliance were observed for all children. 相似文献

Previous research (Andersen, 1989) has suggested that the recovery of 3-D shape from nonsmooth optic flow (motion transparency) can be performed by segregating surfaces according to the distributions of velocities present in the flow field. Five experiments were conducted to examine this hypothesis in a surface detection paradigm and to determine the limitations of human observers to detect 3-D surfaces in the presence of noise. Two display types were examined: a flow field that simulateda surface corrugated in depth and a flow field-that simulated a random volume. In addition, two types of noise were examined: a distribution of noise velocities that overlapped or did not overlap the velocity distribution that defined the -surface. Corrugation frequency and surface density were also examined. Detection performance increased with decreasing corrugation frequency, decreasing noise density, and decreasing surface density. Overall, the subjects demonstrated remarkable tolerance to the presence of noise and, for some conditions, could discriminate surface from random conditions when noise density was twice the-surface density. Discrimination accuracy was greater for the nonoverlapping than for the overlapping noise, providing support for an analysis based on the distribution of velocities. 相似文献

The word-frequency mirror effect (more hits and fewer false alarms for low-frequency than for high-frequency words) has intrigued memory researchers, and multiple accounts have been offered to explain the result. In this study, participants were differentially familiarized to various pseudowords in a familiarization phase that spanned multiple weeks. Recognition tests given during the first week of familiarization replicated a result of W. T. Maddox and W. K. Estes (1997) that failed to show the classic word-frequency mirror effect for pseudowords; however, recognition tests given toward the end of training showed the classic mirror pattern. In addition, a stimulus-frequency mirror effect for "remember" vs. "know" judgments was obtained. These data are consistent with an account of the mirror effect that posits the involvement of dual processes for episodic recognition. 相似文献

Recent data have shown that parallel processing by the cerebral hemispheres can expand the capacity of visual working memory for spatial locations (J. F. Delvenne, 2005) and attentional tracking (G. A. Alvarez & P. Cavanagh, 2005). Evidence that parallel processing by the cerebral hemispheres can improve item identification has remained elusive. The authors used a novel variant of the attentional blink paradigm to show that the attentional blink is reduced if targets are divided between the hemispheres rather than directed to a single hemisphere. Parallel processing by the cerebral hemispheres can thus expand the capacity of processes involved in item identification. The authors also show that prior engagement of the attentional system may compromise the processing of items directed to the right visual field. This pseudoextinction may explain the failures of previous attempts to demonstrate that parallel processing can improve item identification (J. F. Delvenne, 2005; S. J. Luck, S. A. Hillyard, G. R. Mangun, & M. S. Gazzaniga, 1989). 相似文献

A recent line of research has suggested that memory systems evolved to encode fitness-relevant information more effectively
than other types of information—a phenomenon known as the “survival processing effect” (Nairne, Thompson, & Pandeirada Journal
of Experimental Psychology: Learning, Memory, and Cognition 33:263–273, 2007). However, the basis for the effect has been debated. In addition, it is unknown whether or not individuals will adjust their
judgments of learning (JOLs) to reflect the survival processing effect. In three experiments, participants rated 16 words
for their relevance to a survival scenario and another 16 words for their relevance to a bank robbery scenario. In Experiment
1A (with no JOLs), the survival processing effect emerged; in Experiment 1B (with JOLs), no survival processing effect emerged,
but JOLs were higher in the survival condition. In both cases, these findings were confounded by higher relevance ratings
in the survival condition. In Experiment 2, relevance was manipulated within each list, and the survival processing effect
was eliminated. Instead, both recall and JOL magnitude were related to level of congruity between the words and type of processing.
Together, these results provide further evidence for the role of congruity in the survival processing effect and JOLs. 相似文献

Relations between children’s imaginary companion status and their engagement in private speech during free play were investigated in a socially diverse sample of 5-year-olds (N = 148). Controlling for socioeconomic status, receptive verbal ability, total number of utterances, and duration of observation, there was a main effect of imaginary companion status on type of private speech. Children who had imaginary companions were more likely to engage in covert private speech compared with their peers who did not have imaginary companions. These results suggest that the private speech of children with imaginary companions is more internalized than that of their peers who do not have imaginary companions and that social engagement with imaginary beings may fulfill a similar role to social engagement with real-life partners in the developmental progression of private speech. 相似文献

Despite advancements in health behavior theory and practice, less than half of the United States population meets physical activity recommendations. Two cross-sectional studies (n = 432; n = 1455) were conducted to explore associations between body satisfaction and Transtheoretical Model (TTM) constructs proposed to explain the physical activity behavior change process. A series of regression analyses were conducted, controlling for demographic and TTM variables, as appropriate. Results indicate that body satisfaction significantly explains 2–8% of variance in the TTM constructs responsible for promoting stage movement. Furthermore, body satisfaction was significantly associated with stages of change representing short (>6 months) and long-term (>5 years) maintenance of physical activity. Future research should continue to examine these construct relationships using more rigorous research designs, with the ultimate goal of implementing body satisfaction components alongside traditionally effective TTM interventions to improve physical activity maintenance. 相似文献
