The basic question of the present experiment was whether people use a combination of arithmetic problem solving strategies to reject false products to multiplication problems or whether they simply use the single most efficient strategy. People had to verify true and false, five and non-five arithmetic problems. Compared with no-rule violation problems, people were faster with (a) five problems that violated the five rule (i.e., N×5=number with 5 or 0 as the final digit; e.g., 15 × 4=62), (b) problems that violated the parity rule (i.e., to be true, a product must be even if either or both of its multipliers is even; otherwise, it must be odd; 4 × 38=149), and (c) problems that violated both the parity and five rules (e.g., 29 × 5=142). Finally, people were equally fast and accurate when they solved two-rule violation problems than when they solved five-rule violation problems, and faster for those two types of problems than for parity-rule violation problems. Clearly, people use the single most efficient strategy when they reject false product to multiplication problems. This result has implications for our understanding of strategy selection in both arithmetic in particular and human cognition in general.

When, how, and why students use conceptual knowledge during math problem solving is not well understood. We propose that when solving routine problems, students are more likely to recruit conceptual knowledge if their procedural knowledge is weak than if it is strong, and that in this context, metacognitive processes, specifically feelings of doubt, mediate interactions between procedural and conceptual knowledge. To test these hypotheses, in two studies (Ns = 64 and 138), university students solved fraction and decimal arithmetic problems while thinking aloud; verbal protocols and written work were coded for overt uses of conceptual knowledge and displays of doubt. Consistent with the hypotheses, use of conceptual knowledge during calculation was not significantly positively associated with accuracy, but was positively associated with displays of doubt, which were negatively associated with accuracy. In Study 1, participants also explained solutions to rational arithmetic problems; using conceptual knowledge in this context was positively correlated with calculation accuracy, but only among participants who did not use conceptual knowledge during calculation, suggesting that the correlation did not reflect “online” effects of using conceptual knowledge. In Study 2, participants also completed a nonroutine problem-solving task; displays of doubt on this task were positively associated with accuracy, suggesting that metacognitive processes play different roles when solving routine and nonroutine problems. We discuss implications of the results regarding interactions between procedural knowledge, conceptual knowledge, and metacognitive processes in math problem solving.  相似文献

Retrieval of a multiplication fact (2×6 =12) can disrupt retrieval of its addition counterpart (2+6=8). We investigated whether this retrieval-induced forgetting effect applies to rule-governed arithmetic facts (i.e., 0×N=0, 1×N=N). Participants (n=40) practised rule-governed multiplication problems (e.g., 1×4, 0×5) and multiplication facts (e.g., 2×3, 4×5) for four blocks and then were tested on the addition counterparts (e.g., 1+4, 0+5, 2+3, 4+5) and control additions. Increased addition response times and errors relative to controls occurred only for problems corresponding to multiplication facts, with no problem-specific effects on addition counterparts of rule-governed multiplications. In contrast, the rule-governed 0+N problems provided evidence of generalisation of practice across items, whereas the fact-based 1+N problems did not. These findings support the theory that elementary arithmetic rules and facts involve distinct memory processes, and confirmed that previous, seemly inconsistent findings of RIF in arithmetic owed to the inclusion or exclusion of rule-governed problems.  相似文献

The present research investigated a common yet to date unexamined assumption that individuals are unlikely to savor success when they have not yet fully completed a task. In Study 1 (N = 83), we assessed savoring responses of soccer players who were either winning or were tied at the end of the first half (in progress) and at the end of the match (completed). In Study 2 (N = 121 undergraduates), performance feedback (successful vs. average) and task completion (in progress vs. completed) were manipulated and savoring was assessed. In both studies, successful individuals reported savoring their positive experience less when the task was in progress as compared to completed. Results of a third study (N = 152 undergraduates) showed that lower savoring of success was due to individuals’ focus on and worries about future performance as well as the perception that positive emotions have limited utility. We discuss these findings in terms of the consequences for performance and well-being.  相似文献

This study investigated the roles of different executive function (EF) components (inhibition, shifting, and working memory) in 2-step arithmetic word problem solving. A sample of 139 children aged 8 years old and regularly attending the 3rd grade of primary school were tested on 6 EF tasks measuring different EF components, a reading task and a reading comprehension task, an arithmetic facts task evaluating basic knowledge of calculation, and three 2-step arithmetic word problems. Multiple hierarchical regression analyses were conducted to investigate the roles of the different EF components in the various phases of the problem-solving process. The results showed that EF affects the various phases of problem solving differently over and above calculation knowledge and reading abilities. The implications of these findings are discussed in relation to further understanding the role of cognitive skills in mathematical problem solving and in relation to instructional approaches that may increase children’s performance on 2-step arithmetic word problems.  相似文献

The present review adopts an action control perspective on emotion regulation, contextualising the gap between emotion control goals (e.g., I want to remain calm) and emotional outcomes (e.g., anger, anxiety, and aggression) in terms of the broader literature on goal pursuit. We propose that failure to effectively regulate emotions can result from difficulties with the self-regulatory tasks of (i) identifying the need to regulate, (ii) deciding whether and how to regulate, and (iii) enacting a regulation strategy. Next we review evidence that a technique traditionally associated with regulating behavioural goals (forming implementation intentions or “if-then” planning) can help to overcome these difficulties. Meta-analysis indicated that forming implementation intentions is effective in modifying emotional outcomes, with a large effect relative to no regulation instructions (k = 21, N = 1306 d + = 0.91, 95% CI = 0.61 to 1.20) and a medium-sized effect relative to goal intention instructions (k = 29, N = 1208, d + = 0.53, 95% CI = 0.42 to 0.65). Our conclusion is that research on emotion regulation might benefit from an action control perspective and the interventions that this perspective offers.  相似文献

Attention toward social entrepreneurship has increased worldwide, particularly within younger generations. Based on the identified model of social entrepreneurial intentions, this study proposed a multiple mediation framework to examine the mediating role of entrepreneurial creativity for university students. It also compared the differences between Taiwanese (N = 311) and Hong Kong students (N = 311). Through a survey using both online and offline channels, the results of Study 1 confirmed the factor structures of the 3 scales, involving 5 antecedents of social entrepreneurial intention (i.e., empathy, moral obligation, self-efficacy, perceived social support, and prior experience with social problems), 2 factors of entrepreneurial creativity (i.e., originality and usefulness), and 2 factors of social entrepreneurial intention (i.e. conviction and preparation). The results of Study 2 supported the proposed multiple mediation model across regions. Prior experience with social problems, perceived social support, and originality were identified as the 3 most influential factors affecting the social entrepreneurial intentions of university students. The major differences between Taiwan and Hong Kong involved prior experience, empathy, self-efficacy, perceived social support, and usefulness.  相似文献

Although infants’ cognitions about the world must be influenced by experience, little research has directly assessed the relation between everyday experience and infants’ visual cognition in the laboratory. Eye-tracking procedures were used to measure 4-month-old infants’ eye movements as they visually investigated a series of images. Infants with pet experience (N = 27) directed a greater proportion of their looking at the most informative region of animal stimuli—the head—compared with infants without such experience (N = 21); the two groups of infants did not differ in their scanning of images of human faces or vehicles. Thus, infants’ visual cognitions are influenced by everyday experience, and theories of cognitive development in infancy must account for the effect of experience on development.  相似文献

This study investigated individual differences in cognitive abilities that contribute to solving insight problems. A model is proposed describing three types of cognitive ability that contribute independently to insight: convergent thinking, divergent thinking, and breaking frame. The model was tested in a large sample (N = 108) by regressing insight problem solving performance on measures of these three abilities. This analysis demonstrated that all three abilities predicted insight independently. Convergent thinking was further broken down into verbal intelligence and working memory, which also predicted insight independently of each other and of divergent thinking and breaking frame. Finally, when pitted against noninsight problem solving as a predictor in regression, only insight problem solving was uniquely associated with divergent thinking and breaking frame. The model is suggested as a potentially useful taxonomy for the study of ill-defined problems and cognitive abilities.  相似文献

Psychological factors are known to play an important part in the origin of many medical conditions including hypertension. Recent studies have reported elevated blood pressure (even in the normal range of variation) to be associated with a reduced responsiveness to emotions or ‘emotional dampening’. Our aim was to assess emotional dampening in individuals with more extreme blood pressure levels including prehypertensives (N = 58) and hypertensives (N = 60) by comparing their emotion recognition ability with normotensives (N = 57). Participants completed novel facial emotion matching and facial emotion labelling tasks following blood pressure measurement and their accuracy of emotion recognition and average response times were compared. The normotensives demonstrated a significantly higher accuracy of emotion recognition than the prehypertensives and the hypertensives in labelling of facial emotions. This difference generalised to the task where two facial halves (upper & lower) had to be matched on the basis of emotions. In neither the labelling nor matching emotion conditions did the groups differ in their speed of emotion processing. Findings of the present study extend reports of ‘emotional dampening’ to hypertensives as well as to those at-risk for developing hypertension (i.e. prehypertensives) and have important implications for understanding the psychological component of such medical conditions as hypertension.  相似文献

This study investigated longitudinal pathways leading from early spatial skills in first-grade girls to their fifth-grade analytical math reasoning abilities (= 138). First-grade assessments included spatial skills, verbal skills, addition/subtraction skills, and frequency of choice of a decomposition or retrieval strategy on the addition/subtraction problems. In fifth grade, girls were given an arithmetic fluency test, a mental rotation spatial task, and a numeric and algebra math reasoning test. Using structural equation modeling, the estimated path model accounted for 87% of the variance in math reasoning. First-grade spatial skills had a direct pathway to fifth-grade math reasoning as well as an indirect pathway through first-grade decomposition strategy use. The total effect of first-grade spatial skills was significantly higher in predicting fifth-grade math reasoning than all other predictors. First-grade decomposition strategy use had the second strongest total effect, while retrieval strategy use did not predict fifth-grade math reasoning. It was first-grade spatial skills (not fifth-grade) that directly predicted fifth-grade math reasoning. Consequently, the results support the importance of early spatial skills in predicting later math. As expected, decomposition strategy use in first grade was linked to fifth-grade math reasoning indirectly through first-grade arithmetic accuracy and fifth-grade arithmetic fluency. However, frequency of first-grade decomposition use also showed a direct pathway to fifth-grade arithmetic reasoning, again stressing the importance of these early cognitive processes on later math reasoning.  相似文献

Religious and spiritual struggles involve tensions, conflicts, and strains pertaining to religious and spiritual life. This research examined whether broad measures of religiousness predicted differences in the development and resolution of struggles over 1 year in a sample of undergraduates (N = 451) from three U.S. universities: secular public (n = 146), secular private (n = 126), and faith-based Christian (n = 179). Latent class growth analyses indicated 4 distinct trajectories of change in struggles. One group reported consistently low levels of struggles (n = 298, 66% of total sample); another developed struggles over a 1-year period (n = 100, 22%); a third reported high levels of struggles during both years (= 19, 4%); and the final group reported resolving their struggles over 1 year (n = 34, 8%). Penalized multinomial logistic regressions indicated that religious belief salience predicted the development of struggles longitudinally. We discuss the implications of these findings.  相似文献

Two studies provide evidence for distinguishing intellectual humility (IH) from general humility (GH). Humility involves (a) an Accurate View of Self and (b) the ability to regulate egotism and cultivate an other-oriented stance; IH is a subdomain of humility that involves (a) having an accurate view of one’s intellectual strengths and limitations and (b) the ability to negotiate ideas in a fair and inoffensive manner. First, we present a theoretical framework for distinguishing these constructs. In Study 1, with a sample of undergraduate students (N = 1097), we used confirmatory factor analysis to provide empirical evidence for this distinction. We also found that IH predicted unique variance in openness to experience relative to GH. In Study 2, we examined additional evidence of discriminant validity with another sample of college students (N = 355). IH also predicted unique variance in need for cognition, objectivism, and religious ethnocentrism relative to GH.  相似文献

Prior knowledge in the domain of mathematics can sometimes interfere with learning and performance in that domain. One of the best examples of this phenomenon is in students’ difficulties solving equations with operations on both sides of the equal sign. Elementary school children in the U.S. typically acquire incorrect, operational schemata rather than correct, relational schemata for interpreting equations. Researchers have argued that these operational schemata are never unlearned and can continue to affect performance for years to come, even after relational schemata are learned. In the present study, we investigated whether and how operational schemata negatively affect undergraduates’ performance on equations. We monitored the eye movements of 64 undergraduate students while they solved a set of equations that are typically used to assess children’s adherence to operational schemata (e.g., 3 + 4 + 5 = 3 + __). Participants did not perform at ceiling on these equations, particularly when under time pressure. Converging evidence from performance and eye movements showed that operational schemata are sometimes activated instead of relational schemata. Eye movement patterns reflective of the activation of relational schemata were specifically lacking when participants solved equations by adding up all the numbers or adding the numbers before the equal sign, but not when they used other types of incorrect strategies. These findings demonstrate that the negative effects of acquiring operational schemata extend far beyond elementary school.  相似文献

The present research investigated different types of social class identification as moderators of the negative relation between social class and mental health problems. Psychology undergraduates (N = 355) completed an online survey that included measures of social class, mental health and well-being, and three aspects of social class identification: importance of identity, salience of identity, and perceived self-class similarity. Perceived self-class similarity buffered the negative association between social class and depressive symptoms. However, importance and salience of social class identity amplified the associations between social class and anxiety and life satisfaction. These findings contribute to a more sophisticated understanding of the way in which social identification may operate as a social cure.  相似文献

Despite the popularity of the ‘pay it forward’ (PIF) concept in textbooks and popular culture, to date, no study has tested the effectiveness of a brief, one-time PIF activity on the well-being of those who do good and those who receive good. To test this, 83 undergraduates (‘givers’) performed random kind acts for 1.5 h. PIF resulted in a wide range of well-being benefits for givers (e.g. greater positive and lower negative affect), with females showing greater positive affect benefits. Receivers of kindness (N = 1014) also benefited as evidenced by greater smiling behavior and more sincere smiles vs. controls (N = 251). Of the 48 receivers who completed a follow-up online questionnaire, the majority indicated that they would also PIF, with almost 40% indicating that they already had. Results indicate that a one-time brief PIF intervention can have broad benefits for those involved.  相似文献

ABSTRACT

In samples of Americans (N = 273) and Indians (N = 194) paid through Mechanical Turk (Study 1) and British (N = 132) volunteers contacted through Reddit (Study 2), we examined how the Dark Triad traits (i.e., psychopathy, narcissism, and Machiavellianism) were associated with happiness expectations when participants imagined solving adaptive tasks. In Study 1, the traits were linked to forecasted happiness in achieving status and power and mate-seeking, with psychopathy demonstrating less happiness when pursuing slow life history tasks (e.g., avoiding diseases), whereas the other two traits led to expectations of happiness when forming social bonds, retaining mates, and avoiding pathogens. In Study 2, the traits were associated with choosing to pursue mating opportunities to induce happiness. Women expected more happiness in response to ensuring their safety over pursuing mating opportunities. We suggest happiness might be an affective feedback system that rewards people for pursuing their life history goals.  相似文献

When families migrate the new culture and culture of origin may conflict, with possible consequences for parenting and children's development. Turks form one of the largest immigrant groups in Western Europe, and there is also much movement within Turkey. This study compares three groups; Turkish immigrants to the UK (N = 142), migrants within Turkey (N = 229), and Turkish non-migrants (locals, N = 396). The children were 39–71 months old (M = 58 months, SD = 6.5), 392 were boys and 375 were girls. Parents supplied data on family characteristics and parenting, and teachers supplied data on children's behaviour. Using Baumrind's parenting model and allowing for background effects, compared to non-migrants and migrants, the immigrant parents were less permissive and more authoritarian. Children in immigrant families had more externalizing problems, internalizing problems and emotional dysregulation and less social competence than migrant and non-migrant children. Multilevel models and structural equation models both found that these effects upon child behaviour were evident after taking into account demographic factors and were not eliminated by taking into account parenting style differences, and thus suggest that immigration and migration are risk factors for child behaviour. Effects of immigrant and migrant status were partly direct and partly indirect via their effects on parenting.  相似文献

Neurodevelopmental delays are known to occur in children with metopic synostosis, but it is presently unclear whether the cognitive, behavioral and psychological outcomes of children with metopic synostosis differ to those of their healthy peers. This meta-analysis consolidated data from 17 studies (published prior to August 2017) that examined the cognitive, behavioral and psychological outcomes of children (n = 666; aged ≤19 yrs) with metopic synostosis. Hedges’g (gw) effect sizes compared the outcomes of samples with metopic synostosis (unoperated, operated) to healthy controls or normative data and, where available, the prevalence of problems/disorders was calculated. Children with unoperated metopic synostosis performed significantly worse than their healthy peers on measures of: general cognition (gw = ?.38), motor functioning, (gw = ?.81), and verbal (gw = ?.82) and visuospatial (gw = ?.92) abilities. Children with operated metopic synostosis performed significantly worse on measures of motor functioning (gw = ?.45), visuospatial skills (gw = ?.32), attention (gw = ?.50), executive functioning (gw = ?.36), arithmetic ability (gw = ?.37), and behavior (gw = ?.34). Cognitive, behavioral, and psychological problems were prevalent, but variable. Overall, the cognitive, behavioral, and psychological outcomes of children with metopic synostosis are generally worse than their healthy peers, regardless of surgical status. However, research is sparse, samples small, controls are rarely recruited, and the severity of metopic synostosis often not stated. Nevertheless, the findings suggest that children with metopic synostosis are likely to experience a variety of negative outcomes and should therefore receive ongoing monitoring and support.  相似文献

Humility is marked by the regulation of selfish impulses for the sake of others, including holding a modest view of one’s beliefs (and their relative strengths and weaknesses). In three studies, we evaluated the extent to which humility attenuates negative attitudes, behavioral intentions, and behaviors toward religious out-group members. In Study 1 (N = 159), humility regarding religious beliefs was associated with positive attitudes toward religiously different individuals. In Study 2 (N = 149), relational and intellectual humility were associated with less aggressive behavioral intentions in a hypothetical situation in which their cherished beliefs were criticized. In Study 3 (N = 62), participants implicitly primed with humility administered significantly less hot sauce (a behavioral measure of aggression) to a religious out-group member who criticized their cherished views relative to participants in the neutral prime condition. We highlight the importance of humility in promoting positive attitudes and behaviors toward religious out-group members.  相似文献
