Discriminability of voice onset time was determined for four naive Ss in order to evaluate the relative efficiency of a testing procedure which utilized confidence ratings along with the conventional oddity task. Ss rated their judgments on oddity trials as “very very sure,” “somewhat sure,” or “just guessing.” Each S’s discrimination scores were given weights according to his ratings, yielding functions that were compared with those computed using unweighted percent correct scores. The confidence-rating technique produced readily interpretable results with about one-third as many judgments as are needed when the conventional procedure is used. Possible problems with the interpretation of the functions and the generalizability of the technique are discussed.  相似文献

Taste quality and intensity shifts following adaptation to NaCl, quinine hydrochloride, sucrose and HCl were investigated in 10 Ss. In each of four sessions, Ss were adapted to water and two concentrations of one taste solution and gave magnitude estimates and quality judgments for a series of concentrations of that solution. Adapting to water produced magnitude estimates which increased with increasing concentration. Quality judgments were typical, e.g., “salty” for NaCl. Adapting to moderate concentrations of taste solutions generally produced magnitude estimates of zero at the adapting concentrations and increasing values for higher and lower (sub-adapting) concentrations. Sub-adapting tastes were atypical. Adaptation to NaCl and sucrose produced bitter sub-adapting tastes and adaptation to HCl and quinine hydrochloride produced sweet sub-adapting tastes. Water, as the lowest sub-adapting “concentration”, produced the largest sub-adapting tastes.  相似文献

The Psychological Stress Evaluator (PSE) detects inaudible frequency changes in the human voice, and it is claimed that the pattern of these changes can provide a measure of psychophysiological arousal. A few studies have given some support to this hypothesis, but further clarifica tion is needed. One major technical problem in this research is that the traditional scoring esyStem is unreliable unless considerable numbers of scores are taken and averaged , The paper presents a conveniently brief scoring system which has fair reliahility, and which correlates significantly with a measure of Critical Flicker Fusion Threshold.  相似文献

Based on the work of Van Dyne, Ang, and Botero (2003 Van Dyne, L., Ang, S. and Botero, I. C. 2003. Conceptualizing employee silence and employee voice as multidimensional constructs. Journal of Management Studies, 40: 13591392. [Crossref], [Web of Science ®] [Google Scholar]), the concept of voice, generally defined as speaking up, was expanded to include three types of voice behaviors: prosocial, acquiescent, and defensive. Prosocial voice is a fundamentally positive form of voice, whereas acquiescent and defensive voice behaviors reflect more negative forms of voice. We examined individual-level personality traits of Agreeableness and Extraversion and group-level participative climate as predictors of supervisor ratings of each voice behavior. Testing these ideas with a multilevel design in a sample of Chinese workers and their managers, results demonstrated support for links of Agreeableness, Extraversion, and participative climate with supervisor ratings of voice behaviors. Further, group-level participative climate moderated relationships between individual-level Agreeableness and voice behaviors.  相似文献

This meta-analysis of 24 studies, comprising 35 independent samples with 18,099 participants, examined the factor structure of the Children’s Depression Inventory (CDI). The 5-factor solution involving Somatic Concerns, Externalizing, Negative Self-Concept, Lack of Personal and Social Interest, and Dysphoric Mood was supported for all samples. The 5-factor solution was appropriate for child, adolescent, general, at-risk/clinical, and English-speaking samples, whereas the 4-factor solution was the best for samples using non-English versions of the CDI. As the factor structure varied among study subgroups, the strength of relations between scale items and their underlying depressive symptoms varied. Hence, comparisons of mean CDI scores can be misleading.  相似文献

The Self-Monitoring Analysis System is a set of microcomputer programs that were developed to remove clinical judgment from the task of behavioral assessment using self-monitoring diaries. The program is written in Turbo Pascal and runs on MS-DOS (16-bit) or CP/M (8-bit) microcomputer systems. The program allows the user to custom design data bases with hundreds of binary, categorical, integral, and real variables. Full-screen data-entry forms can be custom designed, and random access files allow for flexible data entry and editing. The program makes extensive utilization of Pascal’s very flexible data structure capabilities. Dynamic allocation of memory allows the program to maximize its use of available RAM. Data from a patient with diabetes is presented as a case study illustrating the system’s utility.  相似文献

The symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) have been linked to dysfunction in numerous life domains for both children and adults. As such, it is likely that individuals with these and other related symptoms (e.g., sluggish cognitive tempo, SCT) may also experience impaired quality of life. The current study examines the association between ADHD and SCT symptoms and quality of life (QOL) in a community sample of adults. Quality of life data collected from 983 participants (M age = 45.6 years) were analyzed primarily through a series of hierarchical multiple regressions employing SCT and ADHD symptom clusters, demographic, and anxiety and depression scale variables as predictors. Results generally supported the hypothesis that ADHD and SCT symptoms would negatively associate with QOL. Amongst the indicators, inattention and SCT emerged as the strongest predictors of low QOL. These findings underscore the negative impact of ADHD symptoms in adulthood, the independent contribution of SCT, and the importance of considering QOL in prospective research and intervention.  相似文献

Assessing and promoting physical activity and health-related quality of life (HRQOL) have become major public health issues, but little is known regarding HRQOL and its relation with physical activity in adolescents. This study attempted to examine relationships among middle school students’ motivation, physical activity, and HRQOL by using the expectancy-value model as a theoretical framework. Participants were 282 middle school students who responded to a previously validated inventory assessing their motivation, physical activity, and HRQOL. Correlation analyses revealed that expectancy-related beliefs and task values were positively related to physical activity and HRQOL. Physical activity was positively associated with physical, emotional, and social functioning of HRQOL. Regression analyses showed a significant relationship between increasing expectancy-related beliefs and increasing degrees of HRQOL. This research line is promising in that it can provide useful information regarding the translation of theory to practice in influencing adolescents’ physical activity and HRQOL.  相似文献

Recent controversies have questioned the quality of scientific practice in the field of psychology, but these concerns are often based on anecdotes and seemingly isolated cases. To gain a broader perspective, this article applies an objective test for excess success to a large set of articles published in the journal Psychological Science between 2009 and 2012. When empirical studies succeed at a rate much higher than is appropriate for the estimated effects and sample sizes, readers should suspect that unsuccessful findings have been suppressed, the experiments or analyses were improper, or the theory does not properly account for the data. In total, problems appeared for 82 % (36 out of 44) of the articles in Psychological Science that had four or more experiments and could be analyzed.  相似文献

Recent investigations have revealed statistically reliable relationships between signal detection by human subjects performing vigilance tasks and changes in the electrophysiologically recorded waveform of the eyeblink. Thus, this relatively simple and easy-to-obtain measure may have potential use as a predictor of impaired performance. This report describes a study in which eyeblink data were recorded on analog tape while subjects (instrument-rated pilots) “flew” a computer-generated flight plan in a General Aviation Trainer (GAT-1). Eyeblink data were reduced and scored with an adaptation of software from the Washington University Behavioral Research Laboratory. Subjects’ “flying” performance was evaluated with the Pilot Performance Evaluating System (PPES) implemented on a Digital Equipment Corporation (DEC), PDP-11/34 computer. The PPES samples each of four primary flight instruments once per second. It scores performance by generating a combined error score for each maneuver it assigns on the flight-plan display in the cockpit. The PPES/GAT-1 linkup has proved to be a valuable research tool with which to realistically evaluate stress effects and physiological correlates of flying performance in a laboratory setting. This study examined the relationships between eyeblink and flying performance scores collected during a pilot-fatigue study. Analysis of the data supports the use of computers cored eye movement measures as predictors of flying performance decrements.  相似文献

Our study aimed to assess the quality of life (QoL) of patients with congestive heart failure (CHF) and to correlate the different aspects of QoL with relevant socio-demographic variables, CHF severity, somatic comorbidities, other clinical variables and depressive symptomatology. In a cross-sectional study design, a community sample of 103 adult patients with CHF (mean age 68 years, 73 % male) was recruited from an outpatient cardiology practice. CHF severity was assessed with physician ratings of the New York Heart Association (NYHA) functional class and measurement of brain natriuretic peptide (BNP) levels. The psychometric evaluation of quality of life was made using the Medical Outcomes Study Short Form-36 (SF-36) and the Kansas City Cardiomyopathy Questionnaire (KCCQ). The Beck Depression Inventory Second Edition (BDI-II) assessed depressive symptoms. Using multiple linear regression, predictors of poorer QoL included being a female, being older, living alone, NYHA functional class ≥ II, higher levels of BNP comorbidity (such as renal insufficiency and cerebrovascular disease), fluid retention, depressive symptomatology (assessed by BDI-II) and treatment with anti-dyslipidemics, diuretics and β-blockers. Among these correlates, psychological distress was the most strongly related to QoL. Also, functional status measured by NYHA demonstrated a high impact on QoL. Our findings suggest the need to address such factors in developing effective care to improve psychological and functional status in order to enhance QoL in these patients.  相似文献

Cattell's latest version of the 16PF (16PF5) was completed by a random sample of 580 male Anglican clergy whose names and addresses were provided by the Church Commissioners' payroll. These data demonstrate a distinctive profile for clergy that differs significantly from that of the general male population on 12 personality factors. In addition, these data indicate agreement on seven scales, and disagreement on eight scales, between the profiles of male clergy as measured on the old study using the 16PF4 and this study using the new version.  相似文献

Taste profiles were obtained for 16 compounds after adaptation to sucrose, saccharin, and water. Sucrose adaptation reduced the sweetness of all sweet compounds. Saccharin adaptation, when analyzed over all compounds, also reduced sweetness, but the effect was less than that of sucrose. It is concluded that there may be a single receptor mechanism for the sweet quality. Adaptation to sucrose also increased the saltiness, sourness, and bitterness of the other compounds slightly. This increase should be attributed to the taste : induced in water by adaptation to sucrose rather than a potentiation of the other compounds per se.  相似文献

This study investigated the relationship of quality of adolescent’s attachment to mother, father, and peers with depression. 785 high school students (49.7 % male and 50.3 % female) aged between 15 and 17 years completed the Inventory of Parent and Peer Attachment (IPPA) as well as the Beck Depression Inventory (BDI-II). In case of boys the results showed that their attachment to mother, father, and peers were meaningful predictors of depression during adolescence. Similar trend was noted for girls. Attachment to mother across both genders accounted for greater variance in depression in comparison to attachment to father and/or attachment to peers. Cultural implications are addressed.  相似文献

It has been demonstrated that death certificates do not accurately record the actual cause of death in up to one-fourth of cases, as determined from subsequent autopsy findings. The purpose of this study was to explore the use of natural language autopsy data bases as an automated quality assurance mechanism. We translated the account of the major process leading to death, or the primary diagnosis, from all 45,564 narrative autopsy reports obtained at The Johns Hopkins Hospital between May 28, 1889, and June 30, 1987, into the hierarchical system of Medical Subject Heading (MeSH) titles. We obtained a total of 125,772 MeSH title translations, 1,563 of them distinct (average 2.8 per case), ranging in frequency from 6,029 occurrences of LUNG to 1 occurrence apiece of 357 MeSH titles. The natural-language-to-MeSH translations showed expected trends over the past century: fewer infectious diseases; more cardiovascular and neoplastic disease among adults; and more respiratory diseases and congenital malformations in the pediatric age group. The greater availability of autopsy documents in electronic form should increase the value of this resource for quality assurance.  相似文献

We describe the software and hardware of a laboratory running under UCSD Pascal on an Apple II computer. The system includes: two random-access projectors and two standard projectors, all equipped with tachistoscopic shutters; two filter wheels; a voice key; a tone generator; and eight response boxes. The laboratory can be used for any experiment in which visual stimuli are to be presented and in which precise display times, reaction times, and luminances are required. It is particularly well suited to picture-perception and picture-memory experiments.  相似文献

Psychology users of the Unix operating system responded to questionnaire items concerning the use of Unix, the ease of learning and using Unix, and the value and quality of the system for their research needs. The data suggest that Unix is poor according to human-factors criteria, but good according to programming and systems criteria.  相似文献
