Abstract The main approach to rectifying the well documented poor basic life support (BLS) skills of doctors and nurses, based on a Skills Model, has met with only partial success. This study compares the utility of a Skills Model with one that incorporates a cognitive component in predicting BLS skills. Outcome-expectancy, self-efficacy, training and experience of BLS, and BLS ability were assessed in 53 trained nurses. Ability was unrelated to training or experience of BLS. Nurses who scored highest on the BLS skills assessment perceived the procedure as significantly more successful than those with lower scores. Self-efficacy was unrelated to ability, but was related to status: senior nurses were significantly more confident but no more competent in performing BLS than junior nurses. Nurses who had attended more arrests, while more confident, were no more competent than those who had attended fewer. Assessment of BLS skills reduced self-efficacy beliefs. A model for predicting the relationship between self-assessed ability and objectively assessed skill is outlined. 相似文献

Humor tends to predict romantic attraction, but does the style in which it is communicated matter? This study uses experimental methods to test the effects of positive and negative humor styles on short‐term and long‐term romantic interest. The authors randomly assigned 251 participants to read 1 of 4 relationship initiation vignettes depicting either an affiliative or aggressive humor style. Participants reported their short‐term and long‐term interest and made judgments of the relationship initiator's competence and warmth. Results support a fitness indicator model of humor style's role in relationship initiation; positive styles were preferred for long‐term relationships while competence and warmth inferences predicted long‐term attraction. The findings are discussed within the broader context of mate selection goals and challenges. 相似文献

The present research examined whether gender–science stereotypes were associated with science identification and, in turn, science career aspirations among women and men undergraduate science majors. More than 1,700 students enrolled in introductory science courses completed measures of gender–science stereotypes (implicit associations and endorsement of male superiority in science), science identification, and science career aspirations. Results were consistent with theoretically based predictions. Among women, stronger gender–science stereotypes were associated with weaker science identification and, in turn, weaker science career aspirations. By contrast, among men stronger gender–science stereotypes were associated with stronger science identification and, in turn, stronger science career aspirations, particularly among men who were highly gender identified. These two sets of modest but significant findings can accumulate over large populations and across critical time points within a leaky pipeline to meaningfully contribute to gender disparities in STEM domains. 相似文献

Cystic fibrosis (CF) is the most common recessive condition affecting the White British population. Facilitating reproductive
decision making for couples at genetic risk for CF is an important aspect of genetic counseling practice in the UK. The purpose
of this study was to explore the reproductive decision making process for 31 members of CF carrier couples (15 men and 16
women) with or without an affected child. The design involved a qualitative approach consisting of semi-structured interviews
and data analysis informed by grounded theory methodology. Sex and personal experience of CF were identified as factors that
may influence reproductive decision making. Findings suggest these hypotheses: (1) CF carrier couples who have an affected
child/pregnancy, are more likely to embark on another pregnancy than couples who have a healthy child from an at-risk pregnancy,
and (2) men and women play different roles in the reproductive decision making process. Data analysis resulted in development
of a structured framework modeling the reproductive decision making process, which may be helpful in guiding genetic counseling
with CF carrier couples and other at risk couples making reproductive decisions. 相似文献

Fish live in three-dimensional environments, through which they swim with three translational and three rotational degrees
of freedom. Navigating through such environments is recognised as a difficult problem, yet fish, and other animals that swim
and fly, achieve this regularly. Despite this, the vast majority of research has considered how animals navigate horizontally
from place to place and has ignored the vertical component. Here, we test the importance of the vertical axis of space for
fish solving a three-dimensional spatial cognition task. We trained banded tetras (Astyanax fasciatus) to learn the route towards a goal in a rotating Y-maze in which the arms led either up and left or down and right in an
environment that allowed access to visual landmarks providing horizontal and vertical information. Our results revealed that
the landmarks increased navigational efficiency during training. However, these landmarks were ignored when the horizontal
and vertical components were placed in conflict with each other by rotating the maze 90° during testing. From this surprising
result, we conclude that the cues that are present in the vertical axis (presumably hydrostatic pressure) override landmark
cues that have been shown to be salient in experiments that only consider the horizontal component of space. 相似文献

In this research, we test the hypothesis that social status will be an orienting cue to the identification of facial expressions of emotion, particularly angry expressions, especially for those who dispositionally believe that some societal groups should dominate others (Social dominance orientation; Pratto, Sidanius, Stallworth, & Malle, 1994). Using an emotion identification task, the expression of anger was identified with greater accuracy on high-status faces than low-status faces, but only for people who endorsed rigid social hierarchies (i.e., high SDO). Furthermore, people who did not endorse social hierarchies (i.e., low SDO) did not show a preference for high-status anger. Thus, the current findings provide a novel account of how social status can be an informative cue to the expression of anger in online perceptions, especially for those who view social dominance as an important framework for society. 相似文献

For collective action to evolve and be maintained by selection, the mind must be equipped with mechanisms designed to identify free riders--individuals who do not contribute to a collective project but still benefit from it. Once identified, free riders must be either punished or excluded from future collective actions. But what criteria does the mind use to categorize someone as a free rider? An evolutionary analysis suggests that failure to contribute is not sufficient. Failure to contribute can occur by intention or accident, but the adaptive threat is posed by those who are motivated to benefit themselves at the expense of cooperators. In 6 experiments, we show that only individuals with exploitive intentions were categorized as free riders, even when holding their actual level of contribution constant (Studies 1 and 2). In contrast to an evolutionary model, rational choice and reinforcement theory suggest that different contribution levels (leading to different payoffs for their cooperative partners) should be key. When intentions were held constant, however, differences in contribution level were not used to categorize individuals as free riders, although some categorization occurred along a competence dimension (Study 3). Free rider categorization was not due to general tendencies to categorize (Study 4) or to mechanisms that track a broader class of intentional moral violations (Studies 5A and 5B). The results reveal the operation of an evolved concept with features tailored for solving the collective action problems faced by ancestral hunter-gatherers. 相似文献

Little research has been conducted on the psychometrics of the very short scale (36 items) of the Children's Behavior Questionnaire, and no one-item temperament scale has been tested for use in applied work. In this study, 237 United States caregivers completed a survey to define their child's behavioral patterns (i.e., Surgency, Negative Affectivity Effortful Control) using both scales. Psychometrics of the 36-item Children's Behavior Questionnaire were examined using classical test theory, principal factor analysis, and item response modeling. Classical test theory analysis demonstrated adequate internal consistency and factor analysis confirmed a three-factor structure. Potential improvements to the measure were identified using item response modeling. A one-item (three response categories) temperament scale was validated against the three temperament factors of the 36-item scale. The temperament response categories correlated with the temperament factors of the 36-item scale, as expected. The one-item temperament scale may be applicable for clinical use. 相似文献

Circadian rhythms influence a variety of physiological and behavioral processes; however, little is known about how circadian rhythms interact with the organisms' ability to acquire and retain information about their environment. These experiments tested whether rats trained outside their endogenous active period demonstrate the same rate of acquisition, daily performance, and remote memory ability as their nocturnally trained counterparts in tasks of sustained attention and spatial memory. Furthermore, we explored how daily task training influenced circadian patterns of activity. We found that rats demonstrate better acquisition and performance on an operant task requiring attentional effort when trained during the dark-phase. Time of day did not affect acquisition or performance on the Morris water maze; however, when animals were retested 2 wk after their last day of training, they showed better remote memory if training originally occurred during the dark-phase. Finally, attentional, but not spatial, task performance during the light-phase promotes a shift toward diurnality and the synchronization of activity to the time of daily training; this shift was most robust when the demands on the cognitive control of attention were highest. Our findings support a theory of bidirectional interactions between cognitive performance and circadian processes and are consistent with the view that the circadian abnormalities associated with shift-work, aging, and neuropsychiatric illnesses may contribute to the deleterious effects on cognition often present in these populations. Furthermore, these findings suggest that time of day should be an important consideration for a variety of cognitive tasks principally used in psychological and neuroscience research. 相似文献

The assessment and treatment of adults who set fires deliberately are underdeveloped relative to other areas of forensic-clinical psychology. From a scientist–practitioner perspective, all clinical assessment and treatment should be guided by a theoretical and empirically based understanding of the presenting clinical phenomena. In this paper, we critically review current typologies, motives, and theories regarding the etiological features of deliberate adult firesetting. Then, using a theory knitting perspective, we synthesize the prime parts of this information into a comprehensive multifactorial framework of deliberate firesetting. The resulting Multi-Trajectory Theory of Adult Firesetting (M-TTAF) is an integration of current theory, typological, and research knowledge into a comprehensive etiological theory of firesetting along with its maintenance, and desistence. In addition to this overall theoretical framework, we summarize five associated prototypical firesetting trajectories (or patterns of characteristics leading to the firesetting behavior) that stem from our theoretical work. We examine this new theory according to key evaluative components associated with theory construction and conclude by highlighting the M-TTAF's potential application in future research and practice innovation with adult firesetters. 相似文献
