A general on-line eye-movement recording system is described which consists basically of (a) some on-line instrument capable of displaying a visual scene, (b) a device to measure eye position and output position information in the form of electrical signals (c) an analogue-to-digital converter, and (d) a computer. General software for such a system is discussed with emphasis on subroutines which perform calibration and which continuously monitor eye position. 相似文献

Ethical issues in genetic counseling: A comparison of M.S. counselor and medical geneticist perspectives 总被引:1,自引:0,他引:1
New technologies available in the field of medical genetics have increased the importance of responsible ethical decision-making among genetic counselors. A 1985 national survey of M.D. and Ph.D. genetic counselors assessed ethical attitudes using case scenarios designed to simulate dilemmas faced in genetic counseling (Wertz and Fletcher, 1988b). The current study focuses on attitudes of M.S. genetic counselors using similar scenarios, allowing for effective comparisons. M.S. counselors were more willing than M.D. and Ph.D. counselors to maintain patient confidentiality when screening for Huntington's Disease and occupational diseases, and a greater number would agree to counsel patients pursuing prenatal testing for sex selection. A majority of M.S. counselors would disclose an XY karyotype to a phenotypically female patient. M.S. counselors reasoned that respect for patient autonomy and patient confidentiality justified their decisions in many cases. The importance of these principles is discussed and questioned. 相似文献

The impact of mothers' trait anxiety on their expectations of approach‐avoidance behaviour in anxious and non‐anxious children 下载免费PDF全文
Clare M. Bell Allison M. Waters Melanie J. Zimmer‐Gembeck 《Australian journal of psychology》2015,67(1):55-64
This study investigated estimates of approach and avoidance behaviour in clinically anxious and non‐anxious children, and whether mothers' expectations of their children's avoidance differed as a function of high trait anxiety (HTA) versus low trait anxiety (LTA). Participants were 62 clinically anxious and 60 non‐anxious children aged 7–12 years and their mothers. Estimates of avoidance were obtained using an analogue task in which children and mothers were given threat and pleasant information about two novel animals and were asked to estimate children's avoidance of the threat animal's habitat when the threat animal was present (threat condition) and absent (safe condition) from the habitat and when its presence was uncertain (ambiguous condition). Contrary to expectation, anxious children did not differ from controls in estimates of avoidance in any condition. However, relative to HTA mothers of anxious children and LTA mothers of non‐anxious children, HTA mothers estimated greater approach behaviour by their non‐anxious children in the threat condition. Findings suggest that mothers' expectations of children's approach‐avoidance behaviour is influenced by both maternal and child factors. 相似文献

Women are often believed to be more cooperative and less egoistic than men. In the present study, we examined whether people punish women for failing to live up to these benevolent gender stereotypes. Participants played a prisoner's dilemma game with female and male partners who either cooperated or defected. Participants were offered a costly punishment option. They could spend money to decrease the payment of their partners. In Experiment 1, participants spent more money to punish the defection of female in comparison to male partners, but this effect of partner gender on punishment was indirect rather than direct: Participants were more likely to cooperate with female partners than with male partners, which gave them more opportunity for moralistic punishment. In Experiments 2 and 3, we examined the effects of the participants' own gender on cooperation and punishment of female and male partners. Female participants cooperated more with female partners than with male partners while male participants treated female and male partners equally. We conclude that the effect of facial gender on punishment are indirect rather than direct. The results also showed that women, in contrast to men, tended to make decisions that can be considered more social and less rational from an economic point of view, consistent with social‐role theory and evolutionary accounts.

Responses to the Zung Self-Rating Anxiety Scale (SAS: Zung, W. (1971). A rating instrument for anxiety disorders. Psychosomatics, 12, 371–379), the Self-Rating Depression Scale (SDS: Zung, W. (1973). From art to science: The diagnosis and treatment of depression. Archives of General Psychiatry, 29, 328–337) and the Fatigue Severity Scale (FSS) developed by Krupp and colleagues (Krupp, L.B., LaRocca, N.G., Muir-Nash, J., & Steinberg, A.D. (1989). The fatigue severity scale: Application to patients with multiple sclerosis and systemic lupus erythematosus. Archives of Neurology, 46, 1121–1123) were collected from 200 Australian university students to explore the links between these three disorders. Reliability data were satisfactory for all three scales and there were no significant gender or age-related differences between total scale scores. Factor analyses revealed a 5-factor solution for the SAS, a 6-factor solution for the SDS and a single factor for the FSS. There were 8 major and meaningful correlations found and these were entered into a regression of the SAS and SDS factor scores upon the single factor of the FSS. Fatigue factor scores were most powerfully predicted by psychomotor agitation, pain and resultant fatigue and cognitive and emotional arousal factor scores from the SAS and SDS. These data argue for an arousal/anxiety-fatigue-depression progression in disease that may be developmental or accumulative, with extreme levels of psychomotor arousal, resultant muscle fatigue and pain, plus concurrent elevated emotional state and cognitive arousal contributing to an eventual depletion of physical resources, leaving the individual in extreme fatigue. Implications for diagnosis and treatment by counsellors are discussed. 相似文献

Hierarchical clustering is a common way to analyze repertory grid data, as it allows visual identification of homogeneous groups of elements and constructs. This article explores a bootstrap approach to clustering that additionally allows significance testing of dendrogram structures. Given that the choice of the specific clustering method and distance measure can be justified, the method yields indications of closely related element or construct structures. Closely integrated groups of constructs link to the concept of cognitive complexity. Several new complexity indexes are derived from the bootstrap solution. The behavior of the indexes is compared (a) across the most common clustering methods and distance measures and (b) to standard complexity measures. The derived measures reflect a different aspect of complexity than standard measures. 相似文献

The choice behavior of primates, including humans, displays a distance effect: Latency to choose between alternatives appears to increase with smaller differences in value. There is, so far, no demonstration of this effect in birds. Tests of distance effects in birds have been conducted in binary choice situations with a dominant alternative, where one alternative is superior to the other in all aspects that meaningfully contribute to value (e.g., provides access to the same reinforcer, but with a shorter delay). The present study considers the possibility that including dominant alternatives in choice tests precludes distance effects. Four pigeons were presented with binary choices between alternatives that varied in amount and delay. Some choices had a dominant alternative (smaller–sooner or larger–later vs. smaller–later) and some did not (smaller–sooner vs. larger–later). Across phases, only the delay to the smaller–sooner reinforcer varied. Distance effects were expected to be expressed as longer latencies as choice between smaller–sooner and larger–later reinforcers approached indifference. Despite the sensitivity of choice to differences in amount and delay, no distance effect was observed. Alternative explanations for the failure to find a distance effect in pigeon choice, including the Sequential Choice Model (SCM), are discussed. 相似文献

This article presents family-level results from an ongoing study examining the impact of the CHAMP (Chicago HIV prevention and Adolescent Mental health Project) Family Program, a family-based HIV preventative intervention meant to reduce the amount of time spent in situations of sexual possibility and delay initiation of sexual activity for urban youth in the 4th and 5th grades living in neighborhoods with high rates of HIV infection. The CHAMP Family Program has been developed, delivered, and overseen by a collaborative partnership, consisting of community parents, school staff, community-based agency representatives, and university-based researchers. Design of the program was informed by input from this collaborative partnership, child developmental theory of sexual risk, and empirical data gathered from the targeted community. This article presents findings that suggest CHAMP Family Program impact on family communication, family decision-making, and family-level influences hypothesized to be related to later adolescent HIV risk. Implications for future family-based HIV prevention research are discussed here. 相似文献

The use of person-organization fit in employment decision making: an assessment of its criterion-related validity 总被引:3,自引:0,他引:3
Because measures of person-organization (P-O) fit are accountable to the same psychometric and legal standards used for other employment tests when they are used for personnel decision making, the authors assessed the criterion-related validity of P-O fit as a predictor of job performance and turnover. Meta-analyses resulted in estimated true criterion-related validities of .15 (k = 36, N = 5,377) for P-O fit as a predictor of job performance and .24 (k = 8, N = 2,476) as a predictor of turnover, compared with a stronger effect of .31 (k = 109, N = 108,328) for the more commonly studied relation between P-O fit and work attitudes. In contrast to the relations between P-O fit and work attitudes, the lower 95% credibility values for the job performance and turnover relations included zero. In addition, P-O fit's relations with job performance and turnover were partially mediated by work attitudes. Potential concerns pertaining to the use of P-O fit in employment decision making are discussed in light of these results. 相似文献
