Few would argue that the unique insights brought by studying the typical and atypical development of psychological processes are essential to building a comprehensive understanding of the brain. Often, however, the associated challenges of working with non-standard adult populations results in the more complex psychophysical paradigms being rejected as too complex. Recently we created a child- (and clinical group) friendly implementation of one such technique – the reverse-correlation Bubbles approach – and noted an associated performance boost in adult participants. Here, we compare the administration of three different versions of this participant-friendly task in the same adult participants to empirically confirm that introducing elements in the experiment with the sole purpose of improving the participant experience, not only boosts the participant’s engagement and motivation for the task but results in a significantly improved objective task performance and stronger statistical results. 相似文献

Little is known about how posttraumatic growth (PTG) can be fostered and controversy surrounds how it is best measured. We designed and tested an intervention, prospective writing, to facilitate PTG by encouraging people to explore new possibilities after adversity. Adults (N = 188) with recent adverse experiences were randomly assigned to do prospective writing, factual writing, or no writing weekly for one month. PTG was assessed with both retrospective and current-standing measures. Hierarchical linear modeling and response profile analysis were used to assess the intervention’s impact, and latent growth curve modeling was used to test mediation. Prospective writing participants showed the greatest gains in PTG as assessed by the current-standing measure, but did not reliably show greater retrospective PTG than controls. Although large effect sizes for the mediation paths suggested that engagement with new possibilities may be a plausible mechanism, this result fell short of statistical significance. Prospection-based interventions merit further investigation. 相似文献

The most recent edition of the American Psychological Association (APA) Manual states that two spaces should follow the punctuation at the end of a sentence. This is in contrast to the one-space requirement from previous editions. However, to date, there has been no empirical support for either convention. In the current study, participants performed (1) a typing task to assess spacing usage and (2) an eye-tracking experiment to assess the effect that punctuation spacing has on reading performance. Although comprehension was not affected by punctuation spacing, the eye movement record suggested that initial processing of the text was facilitated when periods were followed by two spaces, supporting the change made to the APA Manual. Individuals’ typing usage also influenced these effects such that those who use two spaces following a period showed the greatest overall facilitation from reading with two spaces. 相似文献

Interest in mindfulness-based interventions for children and adolescents is burgeoning, bringing with it the need for validated instruments to assess mindfulness in youths. The present studies were designed to validate among adolescents a measure of mindfulness previously validated for adults (e.g., Brown & Ryan, 2003), which we herein call the Mindful Attention Awareness Scale-Adolescent (MAAS-A). In 2 large samples of healthy 14- to 18-year-olds (N = 595), Study 1 supported a single-factor MAAS-A structure, along with acceptably high internal consistency, test-retest reliability, and both concurrent and incremental validity. In Study 2, with a sample of 102 psychiatric outpatient adolescents age 14-18 years, participants randomized to a mindfulness-based stress reduction intervention showed significant increases in MAAS-A scores from baseline to 3-month follow-up, relative to nonsignificant score changes among treatment-as-usual participants. Increases in MAAS-A scores among mindfulness-based stress reduction participants were significantly related to beneficial changes in numerous mental health indicators. The findings support the reliability and validity of the MAAS-A in normative and mixed psychiatric adolescent populations and suggest that the MAAS-A has utility in mindfulness intervention research. 相似文献

In this study we explored elicitation and habituation of the orienting reflex (OR) in the context of indifferent and significant stimuli, particularly aiming to clarify the mechanism driving dishabituation. An in-depth analysis of the mechanisms of electrodermal habituation and dishabituation was conducted, focusing on the role of state measures as determinants of the phasic response profile. Twenty-four young adult participants completed an auditory dishabituation task while electrodermal activity was recorded. Participants listened to a series of 10 innocuous tones of the same frequency (standards), followed by a deviant tone of a different frequency, and succeeded by 2-4 tones of the same frequency as the initial 10 stimuli. All stimuli had a random stimulus onset asynchrony of 5-7 s. Participants completed an indifferent condition in which there was no task in relation to the stimuli, and a significant condition where instruction was given to count the stimuli silently; order was counterbalanced between participants. As predicted, both skin conductance responses (SCRs) and skin conductance levels (SCLs) were larger for the significant than the indifferent condition. The initial phasic ORs were dependent on pre-stimulus arousal level, and there were significant decreases in both SCR and SCL over the first 10 standards in both conditions. Phasic response recovery was apparent to the deviant stimulus, and dishabituation to the following standard stimulus; both effects were enhanced in the significant condition. Sensitisation was apparent in SCL following the initial and deviant stimuli, but the extent of this was confounded with incomplete resolution of the preceding phasic OR in the significant condition. In the indifferent condition, dishabituation was independent of deviant-related sensitisation; this could not be tested in the significant condition. These findings suggest that dishabituation is not a process of sensitisation, but rather, a disruption of the habituation process. 相似文献

Conceptualizing and measuring functional impairment related to childhood ADHD, particularly within the rapidly growing, yet
underserved, Latino population, is an important area of research that is in its infancy in the field of psychology. The functional
impairments related to academic achievement, social competence, and familial relations experienced by children with ADHD lead
to long-lasting and debilitating difficulties that adversely affect the individuals themselves, their families, and society.
In addition, limited available research suggests that Latino children are at a great or greater risk for developing ADHD,
although they are much less likely to be identified by their parents as displaying problematic behavior and subsequently are
less likely to receive proper assessment and treatment due to several practical and cultural factors. Fortunately, initial
evidence suggests that the construct of functional impairment may be a more universal notion than the potentially culturally
biased measurement of symptomatology. Therefore, in order to provide the best possible outcomes for all children with ADHD,
research needs to be expanded to include examination of functional impairment related to ADHD, particularly when working with
Latino children and their families. Thus, the primary aim of the current review is to examine and critique how the field of
psychology has understood and measured functional impairment in school-aged Latino children with ADHD to date. Based on information
reviewed, suggestions for moving toward a culturally modified assessment of functional impairment related to ADHD in Latino
children will be proposed. This work is a necessary step toward providing culturally appropriate services for a currently
underserved, yet rapidly growing, Latino population in our country. 相似文献

The association between overall life satisfaction (LS) and relationship satisfaction (RS) was investigated longitudinally
among mothers (N=67,355), using data from the Norwegian Mother and Child Cohort Study (MoBa), conducted by the Norwegian Institute
of Public Health. Data were collected twice during pregnancy, and at 6 and 36 months postpartum. Satisfaction increased during
pregnancy, with RS decreasing immediately following birth and LS showing an initial increase followed by a decrease postpartum.
The results showed that LS and RS levels were quite stable over time (.46-.75), as was their cross-sectional associations
(.42-.59). Structural equation modeling using a cross-lagged longitudinal model evidenced cross-concept cross-time effects
for both LS and RS. The strengths of the cross-effects were asymmetrical and life-phase specific, with RS predicting change
in LS more than LS predicted changes in RS during pregnancy and infancy. Having a satisfying romantic relationship is important
for retaining and increasing future life satisfaction. 相似文献

Male-male competition can shape some behavioral or morphological traits of males. Here we investigate if this competition could play a role in the persistence of the polymorphism of handedness in human populations. A negative frequency-dependent selection mechanism has been hypothesized, based on the fact that left-handed men may benefit from a "surprise" advantage during fighting interactions because they are rare in human populations. This advantage may thereby enhance the probability of survival of left- handed men and/or their reproductive success through an increase in social status. In this study, we first explored the association between hand preference and lifetime fighting behavior in a population of 1,161 French men. No effect of hand preference on the probability of fighting was detected, suggesting that the innate propensity to fight does not differ between left- and right-handers. However, among men who had been involved in at least one fight during their lifetime, left-handers reported significantly more fights than right-handers. To explore the biological basis of this behavior, we also investigated the testosterone concentration in saliva samples from 64 French university students. Consistent with frequencies of fights, we found a significantly higher average testosterone concentration in left-handers than in right-handers. We suggest that these behavioral and hormonal differences may be acquired throughout life due to previous experiences in a social context and may favor the persistence of left-handers in humans. 相似文献
