The purpose of this study was to develop a measure for self‐monitoring and self‐regulation of momentary mood states. The Two‐Dimensional Mood Scale (TDMS), consisting of eight words selected on the basis of pleasure and arousal, was created as an efficient measure of self‐monitoring. In Study 1, the validity and reliability of the TDMS were examined by administering the measure to 904 university students. Structural equation modeling revealed that mood states were constructed of two components, arousal and pleasure, and factor analysis found two factors, vitality and stability. In Study 2, differences between two mood manipulations, activation (exercise) and relaxation techniques were examined in 224 university students. The results showed that exercise induced higher vitality (, ) but no change in stability (, ), while relaxation resulted in an increase in stability (, ) but no change in vitality (, ). The TDMS can be combined with various mood manipulations to enable individuals to self‐regulate and alter negative psychological states.  相似文献

We consider multi‐set data consisting of observations, k = 1,…, K (e.g., subject scores), on J variables in K different samples. We introduce a factor model for the J × J covariance matrices , k = 1,…, K, where the common part is modelled by Parafac2 and the unique variances , k = 1,…, K, are diagonal. The Parafac2 model implies a common loadings matrix that is rescaled for each k, and a common factor correlation matrix. We estimate the unique variances by minimum rank factor analysis on for each k. The factors can be chosen orthogonal or oblique. We present a novel algorithm to estimate the Parafac2 part and demonstrate its performance in a simulation study. Also, we fit our model to a data set in the literature. Our model is easy to estimate and interpret. The unique variances, the factor correlation matrix and the communalities are guaranteed to be proper, and a percentage of explained common variance can be computed for each k. Also, the Parafac2 part is rotationally unique under mild conditions.  相似文献

The relationship between the General Factor of Personality (GFP) and several work‐related outcomes such as job performance and organizational citizenship behavior was examined using meta‐analytic data. Confirmatory factor analyses showed sizeable relationships between the GFP and various performance indicators ( = .34), larger than for any of the Big Five dimensions. Controlling for social desirability did not change the relationship between the GFP and job performance. Moreover, regression analyses showed that the GFP accounted for a larger part of the explained variance in the outcome measures than the unique variances of the Big Five. The results add to the evidence for the GFP as a social effectiveness factor and highlight the validity of the GFP in organizational contexts.  相似文献

Let be the knowledge space derived from an attribution function σ on Q. Under an assumption for σ, this paper gives some necessary and sufficient conditions such that is discriminative. It also discusses the resolubility of σ when Q is an infinite set. More precisely, this paper proves that σ is not resoluble if Q is uncountable, and gives a necessary and sufficient condition such that σ is resoluble when is -well-graded. By way of applications of these results, discriminativeness and resolubility are discussed around the merge of skill multimaps and the meshing of the delineated knowledge spaces.  相似文献

Khemlani et al. (2018) mischaracterize logic in the course of seeking to show that mental model theory (MMT) can accommodate a form of inference (, let us label it) they find in a high percentage of their subjects. We reveal their mischaracterization and, in so doing, lay a landscape for future modeling by cognitive scientists who may wonder whether human reasoning is consistent with, or perhaps even capturable by, reasoning in a logic or family thereof. Along the way, we note that the properties touted by Khemlani et al. as innovative aspects of MMT-based modeling (e.g., nonmonotonicity) have for decades been, in logic, acknowledged and rigorously specified by families of (implemented) logics. Khemlani et al. (2018) further declare that is “invalid in any modal logic.” We demonstrate this to be false by our introduction (Appendix A) of a new propositional modal logic (within a family of such logics) in which is provably valid, and by the implementation of this logic. A second appendix, B, partially answers the two-part question, “What is a formal logic, and what is it for one to capture empirical phenomena?”  相似文献

Several methods are available to estimate the total and residual amount of heterogeneity in meta‐analysis, leading to different alternatives when estimating the predictive power in mixed‐effects meta‐regression models using the formula proposed by Raudenbush (1994, 2009). In this paper, a simulation study was conducted to compare the performance of seven estimators of these parameters under various realistic scenarios in psychology and related fields. Our results suggest that the number of studies (k) exerts the most important influence on the accuracy of the results, and that precise estimates of the heterogeneity variances and the model predictive power can only be expected with at least 20 and 40 studies, respectively. Increases in the average within‐study sample size () also improved the results for all estimators. Some differences among the accuracy of the estimators were observed, especially under adverse (small k and ) conditions, while the results for the different methods tended to convergence for more optimal scenarios.  相似文献

To represent the state‐of‐the‐art in an effort to understand the relation between personality and risk taking, we selected a popular decision task with characteristics that parallel risk taking in the real world and two personality traits commonly believed to influence risk taking. A meta‐analysis is presented based on 22 studies of the Balloon Analogue Risk Task from which correlations with sensation seeking and impulsivity assessments could be obtained. Results calculated on a total of 2120 participants showed that effect size for the relation of sensation seeking with risk taking was in the small–moderate range ( = .14), whereas the effect size for impulsivity was just around the small effect size threshold ( = .10). Although we considered participants' demographics as moderators, we found only significantly larger effect sizes for the older adolescents and young adults compared with other ages. The findings of the present review supported the view that inconsistencies in personality–risk research were mostly due to random fluctuations of specific effect sizes, rather than to lack of theoretical ties or to measurement unreliability. It is also concluded that studies aimed at relating individual differences in personality to performance in experimental decision tasks need an appropriate sample size to achieve the power to produce significant results.

Research into factors for suicide has revealed relations between trauma exposure and suicidality (e.g., Bridge, Goldstein, & Brent, 2006 ; Joiner, Sachs‐Ericson, Wingate, Brown, Anestis, & Selby, 2007 ) wherein painful and provocative experiences (e.g., nonsuicidal self‐injury [NSSI]) are an important link (e.g., Van Orden, Witte, Cukrowicz, Braithwaite, Selby, & Joiner, 2010 ; Smith, 2013 ). No prior research has assessed the relationship between functions of NSSI and suicidality among childhood trauma survivors. Participants who endorsed childhood trauma exposure (N = 121; Mage = 18.69, range 18–22) completed measures of posttraumatic stress disorder (PTSD) symptoms, NSSI, and suicidality. Multiple regressions assessing whether the four functions of NSSI predicted suicide ideation and past attempts after controlling for PTSD symptom severity found that only social negative reinforcement was associated with SI ( = .304, SE = .243, t = 2.23, p = .028), while only automatic negative reinforcement was associated with past attempts ( = .470, SE = .066, t = 2.25, p = .028). Findings highlight the importance of assessing NSSI functions when assessing suicidality among trauma survivors.  相似文献

Fischer's (1973) linear logistic test model can be used to test hypotheses regarding the effect of covariates on item difficulty and to predict the difficulty of newly constructed test items. However, its assumptions of equal discriminatory power across items and a perfect prediction of item difficulty are never absolutely met. The amount of misfit in an application of a Bayesian version of the model to two subtests of the SON‐R –17 is investigated by means of item fit statistics in the framework of posterior predictive checks and by means of a comparison with a model that allows for residual (co)variance in the item parameters. The effect of the degree of residual (co)variance on the robustness of inferences is investigated in a simulation study.  相似文献

A commonly shared assumption in the field of visual‐word recognition is that retinotopic representations are rapidly converted into abstract representations. Here we examine the role of visual form vs. abstract representations during the early stages of word processing – as measured by masked priming – in young children (3rd and 6th Graders) and adult readers. To maximize the chances of detecting an effect of visual form, we employed a language with a very intricate orthography, Arabic. If visual form plays a role in the early stages of processing, greater benefit would be expected from related primes that have the same visual form (in terms of the ligation pattern between a word's letters) as the target word (e.g.– [ktz b–ktA b] – note that the three initial letters are connected in prime and target) than for those that do not (– [ktxb–ktA b]). Results showed that the magnitude of priming effect relative to an unrelated condition (e.g. –) was remarkably similar for both types of prime. Thus, despite the visual complexity of Arabic orthography, there is fast access to the abstract letter representations not only in adult readers by also in developing readers.  相似文献

Music and mathematics require abstract thinking and using symbolic notations. Controversy exists regarding transfer from musical training to math achievements. The current study examined the effect of two integrated intervention programs representing holistic versus acoustic approaches, on fraction knowledge. Three classes of fourth graders attended 12 lessons on fractions: One class attended the ‘MusiMath’ holistic program (n = 30) focusing on rhythm within the melody. Another class attended the ‘Academic Music’ acoustic program (Courey et al., Educ Stud Math 81:251, 2012) (n = 25) which uses rhythm only. The third class received regular fraction lessons (comparison group, n = 22). Students in both music programs learned to write musical notes and perform rhythmic patterns through clapping and drumming as part of their fraction lessons. They worked toward adding musical notes to produce a number (fraction), and created addition/subtraction problems with musical notes. The music programs used a 4/4 time signature with whole, half, quarter and eighth notes. In the math lessons, the students learned the analogy between musical durations and fractions, but also practiced fractions other than . Music and math were assessed before, immediately following, and 3‐ and 6‐months post‐intervention. Pre‐ to post‐intervention analyses indicated that only the ‘MusiMath’ group showed greater transfer to intervention‐trained and untrained fractions than the comparison group. The ‘Academic Music’ group showed a trend on trained fractions. Although both music groups outperformed the comparison group 3‐ and 6‐months post‐intervention on trained fractions, only the ‘MusiMath’ group demonstrated greater gains in untrained fractions. Gains were more evident in trained than in untrained fractions. A video abstract of this article can be viewed at https://youtu.be/uJ_KWWDO624  相似文献

A probabilistic model is presented for the phase durations in binocular rivalry experiments. The hypothetical construct of inhibition or reaction inhibition is used to account for the length of the successive phases of left‐eye dominance and right‐eye dominance. In accordance with Hull's Postulate X.B. it is assumed that the inhibition increases linearly at rate a1 during periods of left‐eye dominance and decreases linearly at rate a0 during periods of right‐eye dominance. Two different versions of the proposed model are presented: the beta and the Bessel inhibition models. Inhibition fluctuates between the boundaries 0 and 1 in the beta inhibition model and between ?∞ and +∞ in the Bessel inhibition model. The transition rates λ1(t) for switches from a state of left‐eye dominance to a state of right‐eye dominance, and λ0(t) for switches from a state of right‐eye dominance to a state of left‐eye dominance depend on inhibition: , , where l1 is a non‐decreasing function and l0 is a non‐increasing function. In the beta inhibition model and . In the Bessel inhibition model and . Special attention is given to the derivation of the expectation of the stationary phase durations.  相似文献

This study examined the effect of a prior bout of exercise on implicit cognition. Specifically, we examined whether a prior bout of moderate intensity exercise affected performance on a statistical learning task in healthy adults. A total of 42 participants were allocated to one of three conditions—a control group, a group that exercised for 15 min prior to the statistical learning task, and a group that exercised for 30 min prior to the statistical learning task. The participants in the exercise groups cycled at 60% of their respective O2max. Each group demonstrated significant statistical learning, with similar levels of learning among the three groups. Contrary to previous research that has shown that a prior bout of exercise can affect performance on explicit cognitive tasks, the results of the current study suggest that the physiological stress induced by moderate‐intensity exercise does not affect implicit cognition as measured by statistical learning.  相似文献

Mathematical cognition research has largely emphasized concepts that can be directly perceived or grounded in visuospatial referents. These include concrete number systems like natural numbers, integers, and rational numbers. Here, we investigate how a more abstract number system, the irrationals denoted by radical expressions like , is understood across three tasks. Performance on a magnitude comparison task suggests that people interpret irrational numbers (specifically, the radicands of radical expressions) as natural numbers. Strategy self‐reports during a number line estimation task reveal that the spatial locations of irrationals are determined by referencing neighboring perfect squares. Finally, perfect squares facilitate the evaluation of arithmetic expressions. These converging results align with a constellation of related phenomena spanning tasks and number systems of varying complexity. Accordingly, we propose that the task‐specific recruitment of more concrete representations to make sense of more abstract concepts (referential processing) is an important mechanism for teaching and learning mathematics.  相似文献

The most rigorous research on the causal effects of assisted housing on children's outcomes finds no such effects. The present study uses rich longitudinal data from the Panel Study of Income Dynamics, augmented with Census, American Community Survey and U.S. Department of Housing and Urban Development administrative data, to unpack these nil effects. Analyses include 194 children ( age = 6.2 years) living in assisted housing in 1995 or later who were 13–17 years old in 2002 or 2007, and an unassisted comparison group of 215 children who were income‐eligible for, but never received, housing assistance. Results suggested no mean effects of living in assisted housing during childhood on adolescent cognitive, behavior, and health outcomes, addressing selection through propensity score matching and instrumental variables. However, quantile regressions suggest assisted housing provides an added boost for children with the best cognitive performance and fewest behavior problems but has opposite effects on children with the lowest cognitive scores and most behavior problems. Further tests indicate that these differences are not explained either by neighborhood effects or housing quality. A potentially fruitful avenue for future research investigates differences in how parents take advantage of the housing affordability provided by assisted housing to benefit their children.  相似文献

Tipping represents a form of compensation valued at over $50 billion a year in the United States alone. Tipping can be used as an incentive mechanism to reduce a principal–agent problem. An agency problem occurs when the interests of a principal and agent are misaligned, and it is challenging for the principal to monitor or control the activities of the agent. However, past research has been limited in the investigation of the extent to which tipping is effective at addressing this problem. Following an examination of 74 independent studies with 12,271 individuals, meta‐analytic results indicate that there is a small, positive relation between service quality and percentage of a bill tipped ( = .15 without outliers). Yet, in support of the idea behind tipping, relative weights analyses illustrate that service quality was a stronger predictor of percentage of the bill tipped than food quality, frequency of patronage, and dining party size. Evidence also suggests that racial minority servers tend to be tipped less than White servers (Cohen's d = .17), and women tend to be tipped more than men (Cohen's d = .15). Still, given the magnitude of the effect, one might question if tipping is an effective compensation practice to reduce the principal–agent problem. We discuss theoretical and practical implications for future research.  相似文献

We examined the process by which punishment enables forgiveness, testing the proposition that punishment restores a sense of justice to victims, an experience that is empowering. In Study 1 (N = 69), university students received insulting feedback and were given the opportunity (or not) to sanction the offender. In Study 2 (N = 91), participants imagined having the opportunity (or not) to recommend punishment for a person who had vandalized their house. A two‐step mediation model (punishment justice restoration empowerment forgiveness) was supported in these two studies. In Study 3 (N = 227), punishment options were expanded to test the role of victim voice in the context of third‐party and personal retributive and restorative justice responses to workplace bullying, as well as taking into account revenge as an alternative to justice restoration. When victims had voice, empowerment again played a central indirect role in relations between punishment and forgiveness.  相似文献

The Golden Rule, a core precept of many religions, emphasizes the importance of treating others with compassion. We examined whether priming Golden Rule messages would influence Buddhists’ and Christians’ attitudes toward gay people and perceptions that homosexuality is a choice. In a priming task, participants filled in missing words for popular quotations including two Golden Rule messages that were attributed to either Buddha or Jesus. Christians ( N = 585) in the Buddha‐attributed Golden Rule condition showed stronger explicit anti‐gay attitudes and were more likely to agree that homosexuality is a choice than Christians in the Jesus‐attributed or control conditions, = .012, = .035, even after controlling for political orientation and religiosity. Buddhists ( = 394) showed no variation in attitudes across priming conditions, = .001, = .78. Our results suggest that although the Golden Rule has an important influence on believers, its message of compassion may produce more prejudice if it comes from an outgroup source compared to an ingroup source.  相似文献

Previous research has focused on understanding when, why, and how sex differences in creativity occur, as results vary across samples, measures, and methodologies. In the current study we investigated sex differences in creativity among 984 high achieving adolescents in three expertise areas: Sciences, Arts, and Sports. Eight creativity indicators were analyzed: Alternative uses task (AUT) fluency; creative self-efficacy (CSE); intraindividual strengths (difference between CSE and AUT Fluency); five self-reported creativity scales: Self/everyday, scholarly, performance, mechanical/scientific, artistic. The results showed negligible sex differences ( n p 2 = .01), with females performing better in AUT Fluency and males self-rating their CSE higher. No sex differences were found in self/everyday, scholarly and performance creativity. Males self-rated their mechanical/scientific creativity ( n p 2 = .06) higher than females; while females self-rated their artistic creativity ( n p 2 = .02) higher in comparison to males. Our results extend the existing literature by finding negligible sex differences in adolescent expert groups. However, some stereotypical differences emerged, for example, females with Sciences expertise rated their mechanical/scientific creativity lower than males with and even without Sciences expertise. Results call for further investigation into the links between sex differences, expertise, and specific creativity domains.  相似文献
