The present study investigated potential sex differences in preferences for spicy, hot or unusual foods and in food aversions or neophobia. This study also reexamined the issue of a gender difference in preference for sweet foods. Questionnaires concerning past and current food use and preferences as well as food and condiment use in one actual meal were completed by 148 people between 17 and 32 years of age. Their responses clearly support the prediction that men tend to have a stronger preference than women for spicy, hot foods. The results also support the prediction that men are more likely than women to seek unusual and new foods. Both sexes showed the same degree of preference for condiment use. 相似文献

We examined the relative quality of different types of information and its effects on accuracy in personality judgment. Three hundred and forty-four unacquainted undergraduates participated in a small group round-robin rating scheme. In one condition, participants were asked to disclose three things that were very important to them in life. In a second condition, participants were asked to disclose three distinctive personal facts: things that differentiated them from others. We found that (a) people believed values information was more personality-relevant than facts information and (b) although there was no clear advantage for one condition over the other in terms of generalized accuracy, there were some differences across conditions for specific traits. Implications for the study of information quality in personality judgment are discussed. 相似文献

Self/observer agreement on HEXACO-PI-R scale scores was examined as a function of observers’ subjective ratings of acquaintanceship. For each participant (N = 2199), personality self-reports were obtained along with observer reports from a friend. Each factor-level scale displayed a different pattern of upward accuracy (agreement) trends in personality judgment. Self/observer agreement for Extraversion, Emotionality, and Openness was noticeably stronger at lower acquaintanceship than that for Conscientiousness, Agreeableness, and Honesty-Humility. Conscientiousness showed a steep upward accuracy trend across acquaintanceship levels, reaching a level of accuracy comparable to that of Extraversion and Emotionality. Self/observer agreement for Honesty-Humility and Agreeableness showed slower upward trends than that of Conscientiousness. In several cases, facet-level traits within the same broad factor differed in their accuracy trends. 相似文献

Over the past decade, Mokken scale analysis (MSA) has rapidly grown in popularity among researchers from many different research areas. This tutorial provides researchers with a set of techniques and a procedure for their application, such that the construction of scales that have superior measurement properties is further optimized, taking full advantage of the properties of MSA. First, we define the conceptual context of MSA, discuss the two item response theory (IRT) models that constitute the basis of MSA, and discuss how these models differ from other IRT models. Second, we discuss dos and don'ts for MSA; the don'ts include misunderstandings we have frequently encountered with researchers in our three decades of experience with real‐data MSA. Third, we discuss a methodology for MSA on real data that consist of a sample of persons who have provided scores on a set of items that, depending on the composition of the item set, constitute the basis for one or more scales, and we use the methodology to analyse an example real‐data set. 相似文献

This study investigated the agreement between parent and teacher ratings of DSM-IV symptoms of Attention Deficit Hyperactivity Disorder (ADHD) and related disorders: Oppositional Defiant Disorder (ODD) and Conduct Disorder (CD). A sample of 55 children in the age range of 6–12 years with clinically diagnosed ADHD participated in the study. Parents and teachers were asked to complete the Disruptive Behavior Disorder Rating Scale (DBDRS; W. E., Pelham, E. M., Gnagy, K. E., Greenslade, & R. Milich, 1992). No association was found between parent and teacher ratings of inattention and hyperactivity/impulsivity. However, moderate to high levels of agreement were obtained for ratings of symptoms that characterized ODD and CD. The observed low levels of agreement between parent and teacher ratings of ADHD symptoms may be attributed to different perceptions of the problem behavior by parents and teachers, medication effects, or the situation specificity of children's behavior. It is recommended that the diagnostic criterion of symptom pervasiveness for the diagnosis of ADHD be operationalized more clearly. 相似文献

De Vries (1993) discusses Pearson's product-moment correlation, Spearman's rank correlation, and Kendall's rank-correlation coefficient for assessing the association between the rows of two proximity matrices. For each of these he introduces a weighted average variant and a rowwise variant. In this note it is shown that for all three types, the absolute value of the first variant is greater than or equal to the absolute value of the second.The author is obliged to Frits E. Zegers for useful comments on an earlier version of this paper. 相似文献

The separate questions on an essay test or the individual judges on a rater panel may constitute congeneric parts rather than
tau-equivalent parts. Also, it may be necessary to infer the lengths of the congeneric parts from their variances and covariances,
rather than from some obvious feature of each part, such as the range of possible scores. Cronbach's alpha coefficient applied
to such part-tests data will underestimate total score reliability. Several reliability coefficients are developed for such
instruments. They may be regarded as extensions of the coefficient developed by Kristof for a three-part test. 相似文献

Although the quality of observational data is generally evaluated by observer agreement, measures of both observer agreement and accuracy were available in the present study. Videotapes with a criterion protocol were coded by 16 observers. All observers calculated agreement scores both on their own and their partner's data and on a contrived data set misrepresented as data collected by other observers. Compared with agreement scores calculated by the experimenter, observers erroneously inflated their own agreement scores and deflated the agreement scores on the contrived data. Half of the observers (n = 8) had been given instructions emphasizing the importance of accuracy during observation while the other half had been given instructions emphasizing interobserver agreement. Accuracy exceeded agreement for the former group, whereas agreement exceeded accuracy for the latter group. The implications are that agreement should be calculated by the experimenter and that the accuracy-agreement relationship can be altered by differential observer instructions. 相似文献
