A comparison of the accuracy and reactivity of methods of monitoring male sexual behavior

Two self-report methods of monitoring male sexuality have been compared—an ongoing method in the form of a diary card and one eliciting retrospective reports in the form of a monthly sexuality interview. Male volunteers were assigned at random to three testing conditions: (a) diary card and monthly interview for 3 months (N=29); (b) three monthly interviews (N=18); and (c) pre- and postinterview only, separated by 2 months (N=21). The correspondence among frequency reports, quality ratings, and number of sexual problems as obtained in diary card and interview measures was examined for respondents in the first condition, revealing that coital frequency and quality ratings were generally quite similar in the two modes of assessment. Interview responses for all subjects were examined for the existence of differential reactive effects according to the frequency of the assessment regimen. No differences emerged among conditions, although a trend for all groups over time was identified. Implications of the results are considered for clinical trials monitoring the effects of new contraceptive methods on sexual functioning.This study was supported by the World Health Organization's Special Programme of Research Development and Research Training in Human Reproduction (Project Nos. 76297 and 79003) and was conducted at King's College Hospital, London.     

Negation: A rejoinder to Wales and Grieve

Wales and Grieve (1969) report an experiment in which they show that a factor of “confusability” affects the comprehension of affirmative and negative sentences, and then claim that this is a relevant factor in explaining the difficulty of negatives. The present paper submits arguments and experimental evidence to dispute this claim.     

A comparison of three measures of the motive to avoid failure:

Individual's motive to avoid failure has typically been assessed by one of three different measures, the Hostile Press scoring system, the Test Anxiety Questionnaire, and Resultant Achievement Motivation. The present research tested the ability of these three measures to predict the two major behavioral criteria of the motive to avoid failure: defensiveness on level of aspiration tasks, and choice of extreme (high or low) probability of success tasks rather than intermediate level of difficulty tasks. Subjects completed the Thematic Apperception Test, which was scored for need for Achievement and the Hostile Press measure of fear of failure. Subjects also completed the Test Anxiety Questionnaire, the Achievement Test Preference Questionnaire, and an anagram level of aspiration task. The results demonstrated that only the Hostile Press measure was significantly related to the two behavioral criteria, and led the authors to conclude that the Hostile Press measure should be used in future assessment of the fear-of-failure motive.     

Trading accuracy for speed: gender differences on a Stroop task under mild performance anxiety.

A standard Stroop task was used to examine the effect of performance anxiety on 58 male and 69 female undergraduates. Subjects were approached either by two casually dressed experimenters who did not stress speed or accuracy or by 4 or 5 formally dressed experimenters who stressed quick and accurate performance. Subjects were told the test would assess their "mental acuity"; their responses were visibly tape-recorded. Reaction times did not show differential response by anxiety condition; men and women showed different RTs only in the low-anxiety condition, with women performing significantly more slowly. There were no significant differences for the high-anxiety condition. Analysis of errors showed women were more accurate than men. Men traded accuracy for speed and may have been under equal performance stress in both situations. When performance was not stressed, women were slower and more accurate than men. When performance was stressed, women increased their speed to match that of men while maintaining their greater accuracy.     

In search of explanations: A rejoinder to Borkenau

The main points raised by Borkenau against our challenge of the 'intuitive psychometrics' view of personality judgements are discussed, in particular his example of the link between school grades and intelligence. It is argued that the semantic similarity interpretation advanced in our paper is more adequate and more parsimonious than explanations in terms of psychometric reasoning.     

Relating emotional abilities to social functioning: a comparison of self-report and performance measures of emotional intelligence

Three studies used J. D. Mayer and P. Salovey's (1997) theory of emotional intelligence (EI) as a framework to examine the role of emotional abilities (assessed with both self-report and performance measures) in social functioning. Self-ratings were assessed in ways that mapped onto the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), a validated performance measure of EI. In Study 1, self-ratings and MSCEIT scores were not strongly correlated. In Study 2, men's MSCEIT scores, but not self-ratings, correlated with perceived social competence after personality measures were held constant. In Study 3, only the MSCEIT predicted real-time social competence, again, just for men. Implications for analyzing how emotional abilities contribute to social behavior are discussed, as is the importance of incorporating gender into theoretical frameworks and study designs.     

Agonistic and antagonistic interaction in speed/accuracy tradeoff: A delta-lognormal perspective

This paper reports the results of a model-based analysis of movements gathered in a 4 × 4 experimental design of speed/accuracy tradeoffs with variable target distances and width. Our study was performed on a large (120 participants) and varied sample (both genders, wide age range, various health conditions). The delta-lognormal equation was used for data modeling to investigate the interaction between the output of the agonist and the antagonist neuromuscular systems. Empirical observations show that the subjects must correlate more tightly the impulse commands sent to both neuromuscular systems in order to achieve good performances as the difficulty of the task increases whereas the correlation in the timing of the neuromuscular action co-varies with the size of the geometrical properties of the task. These new phenomena are discussed under the paradigm provided by the Kinematic Theory and new research hypotheses are proposed for further investigation of the speed/accuracy tradeoffs.     

A comparison of the efficiency and accuracy of BILOG and LOGIST

Comparisons are made between BILOG version 2.2 and LOGIST 5.0 Version 2.5 in estimating the item parameters, traits, item characteristic functions (ICFs), and test characteristic functions (TCFs) for the three-parameter logistic model. Data analyzed are simulated item responses for 1000 simulees and one 10-item test, four 20-item tests, and four 40-item tests. LOGIST usually was faster than BILOG in producing maximum likelihood estimates. BILOG almost always produced more accurate estimates of individual item parameters. In estimating ICFs and TCFs BILOG was more accurate for the 10-item test, and the two programs were about equally accurate for the 20- and 40-item tests.I am grateful to Robert J. Mislevy, Martha L. Stocking, and Marilyn S. Wingersky for many helpful comments on an earlier version of this paper. I would also like to thank Hamid Kamrani and Bongmyoung Park for getting LOGIST and BILOG running and keeping them running under changing computer systems at CTB/McGraw-Hill.
