Recent experiments have indicated that contrast effects can be obtained with vowels by anchoring a test series with one of the endpoint vowels. These contextual effects cannot be attributed to feature detector fatigue or to the induction of an overt response bias. In the present studies, anchored ABX discrimination functions and signal detection analyses of identification data (before and after anchoring) for an [i]-[I] vowel series were used to demonstrate that [i] and [I] anchoring produce contrast effects by affecting different perceptual mechanisms. The effects of [i] anchoring were to increase within-[i] category sensitivity, while [I] anchoring shifted criterion placements. When vowels were placed in CVC syllables to reduce available auditory memory, there was a significant decrease in the size of the [I]-anchor contrast effects. The magnitude of the [i]-anchor effect was unaffected by the reduction in vowel information available in auditory memory. These results suggest that [i] and [I] anchors affect mechanisms at different levels of processing. The [i] anchoring results may reflect normalization processes in speech perception that operate at an early level of perceptual processing, while the [I] anchoring results represent changes in response criterion mediated by auditory memory for vowel information. 相似文献

Three linguists reliably judged the accentedness of 32 Mexican-Americans and four Anglo male readers using a 7-point Preliminary Accentedness Scale. Next, the judges provided reliable assessments of the relative frequency of 18 types of accented pronunciation for nine of the speakers. An Accentedness Index was developed by averaging the relative frequencies over the 18 pronunciations. Accentedness measures produced by the linguists for the nine test speakers were compared with ratings of status, solidarity, and accent given by naive raters in another experiment (Brennan and Brennan, 1978). The Accentedness Index was a significant predictor of the Preliminary Accentedness Scale, of accentedness assessments by the naive listeners, and of status judgments. Pronunciation types were significant predictors both of accent and of status. Results are discussed in terms of validation of the concept of accentedness. Future use of accentedness measures to investigate spontaneous speech and attitudes of listeners toward their own speech is suggested.The present investigation is based upon data collected by the first author for her doctoral dissertation at the university of Notre Dame, and was partially supported by a grant from the National Institutes of Health under Grant NICHD-06921. A preliminary version of this paper was presented at the Linguistic Attitudes Session of the Ninth World Congress of Sociology, Uppsala, Sweden, in August 1978. 相似文献

To assess the development of dichotic ear asymmetries and handedness, 208 male school children were evaluated in kindergarten and at Grades 2 and 5 (ages 66, 92, and 130 months of age, respectively) with a dichotic listening task and a hand preference test. The Wide Range Achievement Test (WRAT) also was administered at each of the three grade levels. There was significant variability in handedness scores over time only for those subjects whose scores at initial testing, that is, in kindergarten, identified them as non-right-handers. Both right and left handers had a significant increase in dichotic listening scores over time; however, only right handers had a significant right ear advantage at each evaluation. Regression analyses showed that combined hand preference scores and ear recall scores at each probe when combined accounted for almost 44% of the variance in WRAT achievement scores at Grade 5. Ear asymmetry scores, however, were not predictive of school achievement. 相似文献

This research examined gender differences in orientations toward autonomous and social achievement. Three independent samples of subjects (total N= 359 males and 574 females) completed measures of achievement orientation (including Strumpfer's [1975] Autonomous Achievement Values and Social Achievement Values scales) and relevant cognitive, affective, and behavioral variables. Correlational and factor analyses clearly identified distinct autonomous and social achievement factors for both men and women in each of the samples. Examination of the correlates of achievement orientation indicated that whereas an autonomous achievement orientation is similarly expressed in males and females, there are considerable sex differences in the expression of an orientation toward social achievement. In particular, a social achievement orientation was associated with concerns over social approval and responsiveness to social influence among males, but was generally unrelated to these factors among females. Findings are discussed in terms of several recent hypotheses concerning the effects of sex role norms on the development and expression of achievement needs in men and women. 相似文献

Although a demand analysis is helpful for identifying potential establishing operations for the functional analysis (FA) demand condition, it may not always be practical due to time constraints. A potential alternative is the Negative Reinforcement Rating Scale (NRRS), an indirect assessment tool that may serve as a time efficient alternative to a demand analysis. The experimenter assessed the reliability and validity of the NRRS for 5 individuals with autism spectrum disorder who exhibited problem behavior. Multiple types of interrater reliability were assessed across 2 informants, and NRRS outcomes were compared to a subsequent demand analysis and FA to assess its validity. Reliability was high (M = 84%) for NRRS numerical ratings of categories but low (M = 32.9%) for specific examples provided. NRRS-identified highly aversive tasks yielded better correspondence with demand analysis outcomes than did NRRS-identified less aversive tasks. 相似文献

A comparison of differential reinforcement procedures for treating automatically reinforced behavior
Children diagnosed with autism spectrum disorder (ASD) often exhibit stereotypy, which can be socially stigmatizing, interfere with daily living skills, and affect skill acquisition. We compared differential reinforcement of alternative behavior (DRA) and differential reinforcement of other behavior (DRO) when neither procedure included response blocking or interruption for (a) reducing stereotypy, (b) increasing task engagement, and (c) increasing task completion. DRA contingencies yielded superior outcomes across each measure when evaluated with 3 individuals with autism spectrum disorder. 相似文献

Social diffusion theory has recently been recognized as a promising approach for large-scale disease prevention and health promotion efforts. This paper describes how principles and tactics from social cognitive theory, operant psychology, social psychology, social marketing, and the overarching stages of change model can be used to further develop the conceptual and strategic (technological) bases of social diffusion theory. Within an integrative framework, we discuss in detail more effective ways to train peer mediators of behavior change as one example of how social diffusion theory can benefit from this conceptual and strategic reformulation. We then further illustrate the use of peer mediators of change in human immunodeficiency virus (HIV) and cancer prevention intervention studies with both interventions training peer mediators to diffuse information, norms, and risk reduction strategies. Although the results of these studies showed reductions in high-risk behaviors across population segments, more closely following the framework discussed in this article should further increase the behavior change potential of future interventions based on social diffusion theory. 相似文献

It has been hypothesized that an evolutionarily ancient mechanism underlies the ability of human infants to detect and act upon the direction of eye gaze of another human face. However, the evidence from behavioral studies with infants is also consistent with a more domain-general system responsive to the lateral motion of stimuli regardless of whether or not eyes are involved. To address this issue three experiments with 4-month-old infants are reported that utilize a standard face-cueing paradigm. In the first experiment an inverted face was used to investigate whether the motion of the pupils elicits the cueing effect regardless of the surrounding face context. In the second experiment pupil motion and eye gaze direction were opposed, allowing us to assess their relative importance. In a third experiment, a more complex gaze shift sequence allowed us to analyse the importance of beginning with a period of mutual gaze. Overall, the results were consistent with the importance of the perceived direction of motion of pupils. However, to be effective in cueing spatial locations this motion needs to be preceded by a period of direct mutual gaze (eye contact). We suggest that evolution results in information-processing biases that shape and constrain the outcome of individual development to eventually result in adult adaptive specializations. 相似文献

This study examined ethnic differences in attachment styles and depression among African American and European American college women. African American women reported less favorable views of others, which suggests that attachment styles emphasizing caution in relationships may be normative and adaptive for these women. There were no differences between groups in views of self or reports of depressive symptoms. Implications for long‐term relationships and counseling are discussed. Este estudio examinó las diferencias étnicas en estilos de apego y depresión entre estudiantes universitarias Afroamericanas y Euroamericanas. Las mujeres Afroamericanas expresaron una visión menos favorable sobre los demás, lo que sugiere que los estilos de apego que enfatizan la precaución en las relaciones pueden ser normativos para estas mujeres, y el resultado de su adaptación. No hubo diferencias entre los grupos en cuanto a la visión de sí mismas o expresión de síntomas depresivos. Se discuten las implicaciones para las relaciones a largo plazo y la consejería. 相似文献
