Isoluminant stimuli are used increasingly often to investigate processes underlying visual word recognition. However, construction of isoluminant stimuli is not straightforward, and inappropriate construction may have the result of misinforming theories that relate word recognition to neurological function. To inform the use of isoluminant stimuli in studies of word recognition, the present article details two experiments in which isoluminant stimuli were constructed using physical onscreen luminance matching and heterochromatic flicker photometry (HFP) with four different stimulus types: disks, squares, rectangles, and letter strings. The findings reveal (1) substantial differences between isoluminance determined by physical onscreen luminance matching and HFP, (2) substantial differences in HFP isoluminance across stimulus types, and (3) substantial differences in HFP isoluminance across participants. These findings indicate that, in contrast to common practice in word recognition research, HFP provides a better indication of isoluminance than physical onscreen matching; but HFP stimuli should match those used in the experiment proper and should be used to assess isoluminance individually for each participant. 相似文献

Previous research on the natural history of smoking has focused on overall group trajectories without considering the possibility of risk subgroup variation. To address this limitation, the authors of the present study aimed to identify subgroups with varying trajectories of smoking behavior. The authors accomplished this within a cohort-sequential study of a large community sample (N = 8,556) with measurements spanning ages 11-31. After removing 2 a priori groups (abstainers and erratics), the authors empirically identified 4 trajectory groups--early stable smokers, late stable smokers, experimenters, and quitters--and psychosocial variables from adolescence and young adulthood were significantly distinguished among them. Given recent advances in quantitative methods, it is now feasible to consider subgroups of trajectories within an overall longitudinal design. 相似文献

The under-representation of women in science, technology, engineering, and math disciplines is of wide interest. In this article we report on the development of new Transtheoretical Model-based measures to assess readiness to take action to advance women scientists. Reliable measures of Stage of Change, Decisional balance, and Self-efficacy were developed with a sample of science faculty from a northeastern university. Theoretical relationships among the constructs were validated and offer support for extending the Transtheoretical Model to this area. These measures are being used as part of a campus-wide initiative to examine the advancement of women scientists before and after a series of interventions. 相似文献

Despite the existence of numerous health-related quality of life (HRQoL) measures, few if any are geared to evaluating the
impact of consumer products. We describe the development and initial implementation of the Farage Quality of Life (FQoL™)
general questionnaire, a self-administered questionnaire to assess the potential impact of a variety of consumer products
on overall well-being and HRQoL. We developed the 27-item FQoL™ measure, scored on a Likert scale and covering Overall Quality
of Life (1 item), Well-Being (12 items), and Energy and Vitality (14 items), and a 3-item Menstrual Module for use with menstruating
women. We assessed test-retest reliability by administering the items twice to a sample of 20 women 3 days apart, calculating
mean absolute differences in responses. Then, in a study of 119 women ages 18–55 years who were randomly assigned to use a
new brand of menstrual pad vs. their usual menstrual pads for 1 menstrual period, we administered the FQoL™ questionnaire
5–7 days before their menstrual period and 5–7 days after the start of their period. We compared changes in responses within
groups and between groups pre- vs. during menstruation. Overall, test-retest reliability was good, with a mean (SD) absolute
difference for the 27 general items of 0.51 (0.31). In the menstrual pad study, the mean (SD) age of responders was 35.3 (7.9)
years; 59 (50%) were age 18–35 and 60 (50%) were age 36–55. Relative to the intervention group, the usual pads group reported
worse HRQoL during vs. pre-menstruation on items addressing self-confidence, managing stress, energy, and fatigue (P ≤ 0.05 for each comparison). In subgroup analyses, relative to intervention patients, women age 18-35 in the usual pads group
reported greater changes for the worse during vs. pre-menstruation in managing stress; energy; and fatigue, but relatively
better work or school attendance during vs. pre-menstruation, and women age 36–55 in the usual pads group reported greater
changes for the worse in self-confidence and in desire to go out in public (P ≤ 0.03 for each comparison). The general FQoL™ is a new measure of HRQoL applicable to consumer product evaluation. It has
good test-retest reliability. The FQoL™ menstrual module detects changes in HRQoL during vs. before the menstrual period associated
with menstrual pad use. Further research is needed to assess the construct validity of the HRQoL. 相似文献

This study compared no-no prompting procedures to simultaneous prompting procedures for 3 children with autism. Using a parallel treatments design, researchers taught rote math skills, receptive labels, or answers to "wh-" questions with both prompting systems. Results indicated that no-no prompting was effective in teaching all skills. By contrast, simultaneous prompting was effective in teaching only one pair of skills to 1 participant in the same amount of teaching time and trials. Researchers conducted a preference assessment to determine which of the two prompting procedures the 3 participants preferred. The participants showed mixed preferences for the two procedures. 相似文献

The present research examines health persuasion from an embodied cognition perspective by proposing that engaging the motor system during health persuasion will lead individuals to engage in healthier behavior and have greater consistency between their intentions and behavior. In two studies, participants watched a health video while either imaging themselves performing the behavior or imaging themselves performing the behavior while also engaging their motor systems with minimal, relevant behaviors. In Study 1, after watching a flossing video, females (but not males) flossed more times in the following week after touching a floss and in Study 2, all participants (males and females) exercised more in the week after watching an exercise video while walking in place. In both experiments, participants who engaged the motor system had stronger intention-behavior consistency than those who merely imagined themselves performing the health behavior. Implications of the findings are discussed for theories of embodied cognition, intention-behavior consistency, and health persuasion. 相似文献
