An irrelevant sequence of discrete auditory tokens disrupts serial recall markedly if successive tokens differ, but the disruption is less marked if the sound is repeated. However, the relation of stimulus mismatch and degree of disruption with serial recall seems to be modulated by organizational principles such as streaming by pitch and streaming by location. The current empirical work replicates the finding that the impact of changing sequences can be reduced if tokens are assigned to different locations in such a way as to form separate streams, each containing sequences of repeated tokens. This study shows that this phenomenon is not a consequence of reducing the number of tokens per stream. 相似文献

To determine whether detailed testimony has equivalent effects on judgments of stereotyped and nonstereotyped defendants, subjects read a synopsis of a criminal court case in which the defendant either was a stereotyped offender or was not. Additionally, the degree of detail in the prosecution testimony and defense testimony was varied. Results indicated that defendant stereotypicality had a greater impact under conditions in which witnesses provided equal amounts of detail in their testimony. When witnesses differed in the degree of detail in their testimony, the stereotypicality of the defendant was disregarded and judgments favored the witness who provided greater detail. These findings suggest that stereotype application is not inevitable; rather, stereotypes may bias jurors' decision-making processes when the quality and quantity of the evidence does not easily lead to a confident judgment. 相似文献

This study investigated auditory discrimination as a function of ethnic group membership within the same socioeconomic status (SES). Subjects were 126 randomly selected six-year-old students attending schools in the lower SES community of southeast San Diego. Only students with no known speech or hearing defects and of normal intelligence were included. They were assigned to one of three categories: Black, Chicano, or Anglo.Subjects were administered four tests in a counterbalanced design: the Wepman, the Gross, and the Ott. The latter two were developed for use with Black dialect and Spanish-speaking youngsters, respectively. The ANOVA results indicated a reliable difference between the main effects of the groups (F=40.34,p<.001) and tests (F=72.82, p<.001), with a significant interaction between tests and groups (F=44.91, p<.001). Interaction effects were evaluated with the Dunn theorem. Significant differences were found among Anglo, Black, and Chicano students on the discrimination list for Spanish sounds (Ott) and a significant Anglo/Black difference on the discrimination test for Black dialect (Gross). Contrary to previous findings, there were no differences between the groups on the Wepman Test of Auditory Discrimination (WTAD). However, there are significant differences between groups on separate items of this test. 相似文献

Three experiments were conducted using a repetition priming paradigm: Auditory word or environmental sound stimuli were identified by subjects in a pre-test phase, which was followed by a perceptual identification task using either sounds or words in the test phase. Identification of an environmental sound was facilitated by prior presentation of the same sound, but not by prior presentation of a spoken label (Experiments 1 and 2). Similarly, spoken word identification was facilitated by previous presentation of the same word, but not when the word had been used to label an environmental sound (Experiment 1). A degree of abstraction was demonstrated in Experiment 3, which revealed a facilitation effect between similar sounds produced by the same type of source. These results are discussed in terms of the Transfer Appropriate Processing, activation, and systems approaches. 相似文献

The open field is a common test of fear, but the apparatus varies widely. Lines painted on the floor facilitate measurement of locomotion (areas entered), but, though some animals balk at lines, this variable has received little attention. In Experiment 1, 10-day-old female chicks were tested individually in an open field with an unmarked floor or one delineated into areas by 1- or 3-mm-wide black lines. In Experiment 2, chicks were tested in pairs in the presence or absence of 3-mm-wide lines. Strong intraindividual correlations demonstrated that both paces and areas entered are effective measures of locomotion. Chicks tested individually were unaffected by the presence or width of lines. Conversely, pair-tested chicks paced and pecked more when the floor was delineated. Given the latter findings, some standardization is recommended. 相似文献

Varying risk factors for both incarceration and mental health diagnoses have been identified for female juveniles, highlighting the need for gender-specific assessments and treatment protocols. The purpose of this study is to determine how the prevalence rates of mental health symptoms differ in male and female juvenile offenders. It was hypothesized that the prevalence rates would be greater for females than males. This study found significant differences between males and females on several clinical scales. These findings are consistent with past studies that have identified differences in mental health symptoms between genders. 相似文献
