The monkey’s capacity to extract tonal pattern from a sequence of tones was assessed in four subjects that had the benefit of substantial past experience in discriminating, matching, and remembering acoustic stimuli. In Experiment 1, the monkeys failed to transfer their well-established matching behavior to the matching of two structured sequences of tones that differed primarily in tonal pattern, indicating that for them tonal pattern was not a salient feature of the acoustic stimuli. Experiment 2 was an attempt to encourage tonal pattern perception by employing, within a discrimination paradigm, very simple tonal patterns and multiple exemplars of the positive and negative patterns; the transfer design, borrowed from Hulse and Cynx (1985), was a powerful one for revealing tonal pattern perception. Verifying earlier results from our laboratory, there was little in the monkeys’ transfer performance to indicate that they had extracted tonal pattern from the acoustic stimuli. Major discriminative control seemed to be vested in the first tone of each exemplar. This apparent cognitive limitation may be rather general among animals, perhaps reflecting an intimate connection between the capacity for tonal pattern perception and that for acoustically based language. 相似文献

We examined the effectiveness of a tactile self‐monitoring prompt to increase on‐task behaviors among 3 elementary‐aged students in a special education classroom. Students were taught to self‐monitor their attention by using the MotivAider (MotivAider, 2000), an electronic beeper that vibrates to provide a tactile cue to self‐monitor. An ABAB reversal design was used for each participant. Results indicated that upon implementation of the self‐monitoring intervention, students increased on‐task behavior from a mean of 55% to more than 90% of the intervals observed. Additionally, teachers and students provided high ratings of treatment acceptability of this self‐monitoring intervention. Limitations, implications, and future directions of these findings are discussed. © 2006 Wiley Periodicals, Inc. Psychol Schs 43: 211–221, 2006. 相似文献

Poverty, Social Support, and Parental Behavior 总被引：9，自引：0，他引：9
The associations among poverty, measures of social support, and parents' reports of punitive and unsupportive behaviors were examined using the National Survey of Families and Households. Analyses revealed a significant interaction between perceived social support and household income: perceived social support was negatively associated with parents' reports of punitive behavior, but mainly when income was low. The amount of help received from others was negatively associated with parents' reports of unsupportive behavior. The study suggests that some forms of social support lower levels of problematic behavior among all parents, whereas other forms of social support are particularly beneficial to parents living in poverty. 相似文献

Targeting Native Hawaiian and other Pacific Islander (NHOPI) children based on their physical activity (PA) stages of change (SOC) may improve intervention effectiveness. No known SOC surveillance system exists for NHOPI jurisdictions. The purpose was to determine the PA SOC prevalence over 5 years in children living in Hawai?i. Self-reported PA SOC from 5 cohorts (3–6 grade students) in Hawai?i were compared between cohorts and sex. The combined PA SOC distribution (n = 1726, 50.7% female) was: Precontemplation, 7.5%; Contemplation, 7.6%; Preparation, 9.9%; Action, 33.4%; Maintenance, 41.5%. There were no significant difference between cohorts 1 and 2 (n = 258), χ2 (16) = 21.75, p = 0.15; 2 and 3 (n = 129), χ2 (16) = 17.51, p = 0.35; 3 and 4 (n = 171), χ2 (16) = 17.28, p = 0.77; 4 and 5 (n = 129), χ2 (16) = 17.51, p = 0.35; and for all cohorts between males and females (p > 0.05). Most participants were in Action and Maintenance. Prevention efforts should emphasize maintaining PA levels. Extending PA behavior surveillance systems to include intention in NHOPI jurisdictions is warranted. 相似文献

Objective. The aims of this article were to test the measurement invariance of the Italian and American versions of the Adult Parental Acceptance–Rejection Questionnaire and to compare adults’ remembrances of parental acceptance–rejection across the two nations. Design. The Adult Parental Acceptance–Rejection Questionnaire was administered to 564 Italian adults (M = 23.04 years) and 509 U.S. American adults (M = 22.09 years), matched by gender and age. The measurement invariance of the Parental Acceptance–Rejection Questionnaire was first established by means of multi-group confirmatory factor analyses. Results. The Parental Acceptance–Rejection Questionnaire is fully invariant across the two cultures, and adults organize their remembrances of mothers’ and fathers’ parenting around the same four classes of behavior in both nations. Italian and American adults tend to remember their parents as having been quite loving, with Italian parents being remembered as slightly less warm and more hostile than American parents. Conclusions. The full invariance of the Parental Acceptance–Rejection Questionnaire across the two populations represents additional strong evidence for the universality of interpersonal acceptance–rejection theory. Measurement invariance also confirmed that the Adult Parental Acceptance–Rejection Questionnaire (short form) can be used to measure adult remembrances of parental acceptance–rejection across these two populations. 相似文献

In making comparative judgments about pairs of stimuli that are linearly ordered, human subjects usually respond faster the greater the separation between-the-items of a test pair—the symbolic distance effect. A similar result has been obtained for associatively related items, such as the alphabet. We report evidence for a distance effect in monkeys tested with pairs of items drawn from a five-item series with which they had considerable previous experience-in a serial learning setting. This finding provides independent evidence that in learning a serial list of items, monkeys acquire knowledge about the ordinal positions of the items. Analysis of the positive results obtained in Experiment 2 and of the failure to find a distance effect in Experiment 1 suggested that in learning a serial list, monkeys construct both an associative chain representation of the series and a spatial representation, with the latter supplying the spatial markers that convey positional information. This dual coding of sequential events, which may be rather general among mammals, probably supports a variety of cognitive competencies. 相似文献
