Investigations of speech often involve the identification of inspiratory loci in continuous recordings of speech. The present
study investigates the accuracy of perceptually determined and acoustically determined inspiratory loci. While wearing a circumferentially
vented mask connected to a pneumotach, 16 participants read two passages. The perceptually determined and acoustically determined
inspiratory loci were compared with the actual loci of inspiration, which were determined aerodynamically. The results showed
that (1) agreement across all three judges was the most accurate of the approaches considered here for detecting inspiratory
loci based on listening; (2) the most accurate pause duration threshold for detecting inspiratory loci was 250 msec; and (3)
the perceptually based breath-group determination was more accurate than the acoustically based determination of pause duration.
Inconsistencies among perceptually determined, acoustically determined, and aerodynamically determined inspiratory loci are
not negligible and, therefore, need to be considered when researchers design experiments on breath groups in speech. 相似文献
The authors review an article (J. Yamamoto & F. Tagami, 2004) published in the Japanese Journal of Counseling Science that described changes in contemporary Japanese family structures and illustrated a therapy process with a father to enhance the father‐son relationship. Implications for the counseling profession in working with men on fathering, including single fatherhood, are shared based on the literature from both the United States and Japan. 相似文献
Counseling can be a vulnerable process for clients and counselors alike. Counselors-in-training often find their early development to be an ambiguous and anxiety-provoking process. Both metaphors and experiential activities are effective methods in counselor training for addressing the ambiguity of counseling and the concerns experienced by counseling students. This article describes how counselor educators can use photography as a metaphor to support counselor development. We also outline four creative photography activities designed to foster self-reflection, professional identity development, and multicultural awareness among counselors-in-training. 相似文献
This paper is concerned with the implication from value to fittingness. I shall argue that those committed to this implication face a serious explanatory challenge. This argument is not intended as a knock-down argument against FA but it will, I think, show that those who endorse the theory incur a particular explanatory burden: to explain how counterfactual (dis)favouring of actual (dis)value is possible. After making two important preliminary points (about one of the primary motivations behind the theory and what this implies, respectively) I briefly discuss an objection to FA made by Krister Bykvist a few years ago. The point of discussing this objection is to enable me to more easily present my own, and I believe stronger, version of that objection. The overall argument takes the form of, simply, a counterexample which can be constructed on the back of (an acceptance) of my two preliminary points. Throughout the paper I try to respond to various objections.
This research introduces the Social Support Opinion Survey (SSOS), the first measure of social support from the provider's perspective. Studies 1–3 developed the SSOS and confirmed that support opinions can be reliably characterized as directive (attempting to govern how others cope) and nondirective (facilitating without governing how others cope). Studies 4–6 showed that social support opinions relate to more basic cognitive, emotional, and interpersonal styles. Directive opinions were related to cognitive rigidity (need for structure, need for certainty, and just‐world beliefs) and to an exchange orientation. Nondirective opinions, in contrast, were related to emotional differentiation, use of emotions as information, empathy, and a communal orientation. Thus, people may reveal who they are by how they help. 相似文献
The visual perception of geographical slant is influenced by physiological resources, such as physical fitness, age, and being physically refreshed. In two studies we tested whether a psychosocial resource, social support, can also affect the visual perception of slants. Participants accompanied by a friend estimated a hill to be less steep when compared to participants who were alone (Study 1). Similarly, participants who thought of a supportive friend during an imagery task saw a hill as less steep than participants who either thought of a neutral person or a disliked person (Study 2). In both studies, the effects of social relationships on visual perception appear to be mediated by relationship quality (i.e., relationship duration, interpersonal closeness, warmth). Artifacts such as mood, social desirability, and social facilitation did not account for these effects. This research demonstrates that an interpersonal phenomenon, social support, can influence visual perception. 相似文献
Recent research has suggested that alterations in mesolimbic dopamine neurotransmission are central to the development and expression of craving for alcohol. Because the D4 dopamine receptor gene, variable numbers of tandem repeats (DRD4 VNTR) polymorphism putatively expresses functional differences in dopamine receptors, the present study tested whether this polymorphism influences the effects of a priming dose of alcohol on craving. Participants consumed 3 alcoholic drinks or 3 control drinks and completed measures of craving after each drink. Participants who were homozygous or heterozygous for the 7 (or longer) repeat allele were classified as DRD4 L, whereas the other participants were classified as DRD4 S. Results suggested that DRD4 L participants demonstrated significantly higher craving after consumption of alcohol as compared with the control beverage. 相似文献
This study examined whether adolescent females with attention-deficit/hyperactivity disorder (ADHD) are differentially responsive
than their male counterparts to extended-release stimulant medications. This investigation may bear special importance for
an adolescent (as opposed to child) population, because hormonal and metabolism differences between sexes are most likely
to emerge at this time. Male (n = 19) and female (n = 16) adolescents, ages 16–19 with ADHD, participated in a randomized, double-blind crossover study evaluating the effectiveness
of osmotic-release methylphenidate, extended release amphetamine salts, placebo, and routine limited medication regimen. Medication
efficacy was evaluated using ADHD symptom ratings from adolescent self-report and parent report, along with objective measures
of inattention and hyperactivity/impulsivity during driving performance and neuropsychological tasks. Males and females were
largely equivalent in impairment, and medication was similarly effective in reducing symptoms. No interactions were found
between sex and medication on any measure of effectiveness or side effects. This finding suggests that the efficacy and tolerability
of extended-release stimulant medications is equivalent for male and female adolescents with ADHD. 相似文献
A real-world open-field search task was implemented with humans as an analogue of Blaisdell and Cook’s (Anim Cogn 8:7–16,
2005) pigeon foraging task and Sturz, Bodily, and Katz’s (Anim Cogn 9:207–217, 2006) human virtual foraging task to 1) determine whether humans were capable of integrating independently learned spatial maps
and 2) make explicit comparisons of mechanisms used by humans to navigate real and virtual environments. Participants searched
for a hidden goal located in one of 16 bins arranged in a 4 × 4 grid. In Phase 1, the goal was hidden between two landmarks
(blue T and red L). In Phase 2, the goal was hidden to the left and in front of a single landmark (blue T). Following training,
goal-absent trials were conducted in which the red L from Phase 1 was presented alone. Bin choices during goal-absent trials
assessed participants’ strategies: association (from Phase 1), generalization (from Phase 2), or integration (combination of Phase 1 and 2). Results were inconsistent with those obtained with pigeons but were consistent with those
obtained with humans in a virtual environment. Specifically, during testing, participants did not integrate independently
learned spatial maps but used a generalization strategy followed by a shift in search behavior away from the test landmark.
These results were confirmed by a control condition in which a novel landmark was presented during testing. Results are consistent
with the bulk of recent findings suggesting the use of alternative navigational strategies to cognitive mapping. Results also
add to a growing body of literature suggesting that virtual environment approaches to the study of spatial learning and memory
have external validity and that spatial mechanisms used by human participants in navigating virtual environments are similar
to those used in navigating real-world environments. 相似文献
