The effect of footwear on locomotor skill performance was examined. 12 children (4 boys, 8 girls; M age = 56.3 mo., SD = 3.3) served as participants. Participants were randomly assigned to perform the locomotor subscale of Ulrich's Test of Gross Motor Development in two shoe conditions (Condition 1: Stride Rite athletic shoes, and Condition 2: flip flop sandals). Children scored significantly higher when wearing athletic shoes than flip-flop sandals. This finding is relevant for motor performance and safety in physical education and movement programs. 相似文献

Most clinicians concede the benefits of conceptualizing children in systemic terms. Yet, many child assessments involve parents only on a limited basis. The Therapeutic Assessment model for children and families (TA-C) emphasizes parental involvement and family-driven collaboration throughout the intervention. Child TA has shown promise as an effective brief intervention (e.g., Smith, Handler, & Nash, 2010; Tharinger et al., 2009). Family intervention sessions (Finn, 2007; Tharinger, Finn, Austin, et al., 2008) are an integral component of the child TA model in facilitating familial changes. However, TA-C research has yet to empirically examine the potential impact of a family session on treatment trajectory. This case study includes an extended presentation of the development and execution of a family session. The authors use a daily measures time-series experiment to empirically examine the clinical effectiveness of the TA-C and the hypothesis that the family session was a tipping point in the trajectory of improvement. 相似文献

Social dominance theory (Sidanius & Pratto, 1999) contends that institutional-level mechanisms exist that reinforce and perpetuate existing group-based inequalities, but very few such mechanisms have been empirically demonstrated. We propose that gendered wording (i.e., masculine- and feminine-themed words, such as those associated with gender stereotypes) may be a heretofore unacknowledged, institutional-level mechanism of inequality maintenance. Employing both archival and experimental analyses, the present research demonstrates that gendered wording commonly employed in job recruitment materials can maintain gender inequality in traditionally male-dominated occupations. Studies 1 and 2 demonstrated the existence of subtle but systematic wording differences within a randomly sampled set of job advertisements. Results indicated that job advertisements for male-dominated areas employed greater masculine wording (i.e., words associated with male stereotypes, such as leader, competitive, dominant) than advertisements within female-dominated areas. No difference in the presence of feminine wording (i.e., words associated with female stereotypes, such as support, understand, interpersonal) emerged across male- and female-dominated areas. Next, the consequences of highly masculine wording were tested across 3 experimental studies. When job advertisements were constructed to include more masculine than feminine wording, participants perceived more men within these occupations (Study 3), and importantly, women found these jobs less appealing (Studies 4 and 5). Results confirmed that perceptions of belongingness (but not perceived skills) mediated the effect of gendered wording on job appeal (Study 5). The function of gendered wording in maintaining traditional gender divisions, implications for gender parity, and theoretical models of inequality are discussed. 相似文献

It is often assumed that observers seek to maximize correct responding during recognition testing by actively adjusting a
decision criterion. However, early research by Wallace (Journal of Experimental Psychology: Human Learning and Memory 4:441–452,
1978) suggested that recognition rates for studied items remained similar, regardless of whether or not the tests contained distractor
items. We extended these findings across three experiments, addressing whether detection rates or observer confidence changed
when participants were presented standard tests (targets and distractors) versus “pure-list” tests (lists composed entirely
of targets or distractors). Even when observers were made aware of the composition of the pure-list test, the endorsement
rates and confidence patterns remained largely similar to those observed during standard testing, suggesting that observers
are typically not striving to maximize the likelihood of success across the test. We discuss the implications for decision
models that assume a likelihood ratio versus a strength decision axis, as well as the implications for prior findings demonstrating
large criterion shifts using target probability manipulations. 相似文献

A novel "field" study recently published in Aggressive Behavior found that individual differences in baseline testosterone concentrations were positively correlated with endorsement of political aggression and that baseline cortisol concentrations were negatively correlated with self-reported aggression among Palestinian boys living in Gaza. Here, we discuss recent evidence indicating that testosterone and cortisol interact to predict competitive, aggressive, and dominant behaviors and urge researchers collecting both hormones to perform and report analyses that formally test for such interaction effects. 相似文献

Three experiments used delay conditioning of magazine approach in rats to examine the summation of responding when two conditioned stimuli (CSs) are presented together as a compound. The duration of each CS varied randomly from trial-to-trial around a mean that differed between the CSs. This meant that the rats' response rate to each CS was systematically related to the reinforcement rate of that CS, but remained steady as time elapsed during the CS (Harris & Carpenter, 2011; Harris, Gharaei, & Pincham, 2011). When the rats were presented with a compound of two CSs that had been conditioned separately, they responded more during the compound than during either of the CSs individually. More significantly, however, in all three experiments, the rats responded to the compound at the same rate as they responded to a third CS that had been reinforced at a rate equal to the sum of the reinforcement rates of the two CSs in compound. We discuss the implications of this finding for associative models (e.g., Rescorla & Wagner, 1972) and rate-based models (Gallistel & Gibbon, 2000) of conditioning. 相似文献

This study examined black-white differences in growth of depressive affect using a longitudinal sample of middle-class, suburban US subjects (n = 956) that spanned from adolescence to early adulthood. Specifically, this study examined whether black-white differences in growth of depressive affect shift over time, and the extent to which that shift, if any, was associated with racial differences in the rate and mental health consequences of early adult social roles (e.g., living arrangements, work/college status, and single-parenthood) and socio-economic status (SES). As expected, growth in depressive affect pivoted around the onset of early adulthood, with the trajectory pivoting upward for Black Americans and downward for White Americans. Due to deficits in SES, the relation between challenging early adult social roles - under/unemployment in particular - and growth in depressive affect was more positive for Black Americans. This differential "vulnerability" appears to underlie racial differences in early adult growth (and by connection contribute to racial differences in growth pivot). The extent to which Black Americans were at a greater risk (relative to White Americans) for an upward pivot increased as the number of challenging roles increased. Black Americans facing only optimal early adult social roles were not at a greater risk, while those facing only challenging social roles were at the greatest risk. 相似文献

Two experiments investigated the effects of interval duration ratio on perception of local timing perturbations, accuracy
of rhythm production, and phase correction in musicians listening to or tapping in synchrony with cyclically repeated auditory
two-interval rhythms. Ratios ranged from simple (1:2) to complex (7:11, 5:13), and from small (5:13 = 0.38) to large (6:7 = 0.86).
Rhythm production and perception exhibited similar ratio-dependent biases: rhythms with small ratios were produced with increased
ratios, and timing perturbations in these rhythms tended to be harder to detect when they locally increased the ratio than
when they reduced it. The opposite held for rhythms with large ratios. This demonstrates a close relation between rhythm perception
and production. Unexpectedly, however, the neutral “attractor” was not the simplest ratio (1:2 = 0.50) but a complex ratio
near 4:7 (= 0.57). Phase correction in response to perturbations was generally rapid and did not show the ratio-dependent
biases observed in rhythm perception and production. Thus, phase correction operates efficiently and autonomously even in
synchronization with rhythms exhibiting complex interval ratios. 相似文献

The case-based time-series design is a viable methodology for treatment outcome research. However, the literature has not fully addressed the problem of missing observations with such autocorrelated data streams. Mainly, to what extent do missing observations compromise inference when observations are not independent? Do the available missing data replacement procedures preserve inferential integrity? Does the extent of autocorrelation matter? We use Monte Carlo simulation modeling of a single-subject intervention study to address these questions. We find power sensitivity to be within acceptable limits across four proportions of missing observations (10%, 20%, 30%, and 40%) when missing data are replaced using the Expectation-Maximization Algorithm, more commonly known as the EM Procedure (Dempster, Laird, &; Rubin, 1977). This applies to data streams with lag-1 autocorrelation estimates under 0.80. As autocorrelation estimates approach 0.80, the replacement procedure yields an unacceptable power profile. The implications of these findings and directions for future research are discussed. 相似文献
