The effects of feature identity in an operant serial feature-negative discrimination (F1 T1−, T1+) were examined in two experiments with rats. In Experiment 1, rats were trained with two operant serial feature-negative discriminations in which different operants were reinforced during two auditory target cues (T1 and T2). The features (F1 and F2) were two neutral cues (visual or auditory stimuli), two motivationally significant cues (flavored sucrose solutions, also used as the operant reinforcers), or one neutral and one motivationally significant cue. Experiment 1 showed that discrimination acquisition, transfer performance, and feature–target interval testing were facilitated with a flavored sucrose feature. Experiment 2 showed that flavored sucrose-alone presentations, more than flavored sucrose trained in a pseudodiscrimination (F1 T1+, T1+), shared several similarities with a standard flavored sucrose feature. The results suggest flavored sucrose rapidly acquires inhibitory properties, which facilitates operant serial feature-negative discrimination performance. 相似文献

Data for nine different indicators of regret were collected from 213 married women with a tubal sterilization and 137 wives of men with a vasectomy at 1,2, and 3 years following surgical sterilization. Relationships between the indicators across the 3 years and within each year were analyzed, using two psychological models. A final, combined model was synthesized and fitted to the data. This model addresses many of the important issues of reliability and validity that have plagued the literature on post-sterilization regret for years. 相似文献

Responses of college students (16 men and 16 women) to the Baldwin illusion showed a significant effect for size of square but not for sex. Findings are consistent with those reported previously by Porac, Coren, Girgus, and Verde for adults and for the oldest group of children tested by Pressey and Wilson. 相似文献

The Dutch Identity is a useful way to reexpress the basic equations of item response models that relate the manifest probabilities to the item response functions (IRFs) and the latent trait distribution. The identity may be exploited in several ways. For example: (a) to suggest how item response models behave for large numbers of items—they are approximate submodels of second-order loglinear models for 2
J
tables; (b) to suggest new ways to assess the dimensionality of the latent trait—principle components analysis of matrices composed of second-order interactions from loglinear models; (c) to give insight into the structure of latent class models; and (d) to illuminate the problem of identifying the IRFs and the latent trait distribution from sample data.This research was supported in part by contract number N00014-87-K-0730 from the Cognitive Science Program of the Office of Naval Research. I realized the usefulness of the identity in Theorem 1 while lecturing in the Netherlands during October, 1986. Because this was in no small part due to the stimulating psychometric atmosphere there, I call the result the Dutch Identity. 相似文献

The effects of a career course taught by 11 instructors (two sections each) for college students, who were undecided about a major field or career, were evaluated in a pre-post design using the Vocational Identity, Occupational Information, and Barrier scales of the My Vocational Situation (J. A. Holland, D. C. Daiger, & P. G. Power, Palo Alto, Calif.: Consulting Psychologists Press, 1980). Large main effects were observed for the Identity and Occupational Information scales, but not for the Barriers scale. No interactions by instructor or student characteristics were found by using a simple ANOVA procedure or by using a split plot factorial design. The implications for new research and career instructors were discussed. 相似文献

The problem of characterizing the manifest probabilities of a latent trait model is considered. The item characteristic curve
is transformed to the item passing-odds curve and a corresponding transformation is made on the distribution of ability. This
results in a useful expression for the manifest probabilities of any latent trait model. The result is then applied to give
a characterization of the Rasch model as a log-linear model for a 2
J
-contingency table. Partial results are also obtained for other models. The question of the identifiability of “guessing”
parameters is also discussed.

A typology was used to organize Census data about kinds of employment, survey data about people's aspirations, and the results of vocational assessments made with and without norms for men and women at two educational levels-some high school or above, and some college or above. Results indicate that kinds of employment differ greatly for different educational levels and between the sexes. The distribution of people's aspirations resembles the distribution of actual employment with some notable exceptions. Results also indicate that the use of sex-based interest inventory norms is unrealistic because they create distributions that diverge greatly from the distribution of actual employment. Some implications of the congruence between kinds of people and their employment are discussed for vocational guidance, test development, and career development research and theory. 相似文献

The psychological meaning and predictive value of a person's vocational aspirations were examined by applying Holland's typology to the vocational aspirations of high school juniors (N = 1005), college juniors (N = 692), employed adults (N = 140), and a second sample of college students studied over a one-year interval (N = 624). The aspirational data were obtained from the Daydreams section of the Self-Directed Search (Holland, 1972). Categorical and correlational analyses show that a person's retrospective vocational aspirations have coherence and yield efficient predictions of subsequently expressed choice. In addition, the degree of coherence or similarity among a person's vocational aspirations provides a potentially useful index of a person's decision-making ability. 相似文献

The author reviews the evidence for the beneficial effects of the Self-Directed Search (SDS), indicates that Hanson and Prediger have misinterpreted the theory, that their evidence is misleading, and that other evidence indicates that males and females of the same type are similar. The virtues of raw scores are summarized. The author recalls some methodological adventures and outlines where we are now in this controversy about the measurement of interests for special groups. 相似文献
