The importance of supportive parent–child interactions and the development of regulatory abilities with regard to growth in children's cognitive abilities has been established. This study investigated the longitudinal relations among parental supportiveness, child task-oriented regulation, and cognitive development for low-income children facing developmental risks. Interlocking growth models were fit to these variables based on measurements made when the children were 14, 24, and 36 months of age. Results showed that growth rates of child cognition were related to baseline (14 months) parental supportiveness and changes in child task-oriented regulation. We additionally found that baseline levels of cognition were related to the baseline levels of child task-oriented regulation. This study suggests that both parental supportiveness during infancy and the concurrent development of child task-oriented regulation are related to cognitive development among children facing developmental risks.  相似文献

Although pregnancy clearly evokes many positive reactions, women's pregnant bodies sometimes inspire negative responses. However, little if any empirical attention has been devoted to understanding the psychological reasons for such ambivalence. In this article we tried to fill this gap by using a conceptual analysis grounded in terror management theory. According to this perspective, because people are motivated to deny their similarity to animals (and the mortal vulnerability that entails), when such concerns are salient, they will react negatively to that which has the potential to highlight the creaturely aspects of humanity (i.e., pregnancy). In two experiments, priming the similarity between humans and animals led participants to respond more negatively to a pregnant compared to non-pregnant Demi Moore magazine cover (Study 1) and to perceive Gwyneth Paltrow as less competent when she was portrayed as pregnant (Study 2). We consider implications for understanding objectification and derogation of women.  相似文献

The mental health literacy (MHL) of rural adolescents has rarely been investigated. This study examined the MHL of 122 rural‐based adolescents (49 males, 73 females) aged 12–18 years (M = 16, SD = 1) using written vignettes and short films to examine knowledge about depression. For the written vignettes, 68% of the rural adolescents were able to correctly identify someone with depression, which is similar to the findings for metropolitan adolescents; however, knowledge about recovery times and avenues of assistance were below that of their metropolitan peers. Participants were less likely to correctly diagnose depression when suicidal intent was not expressed and when the scenario was presented in the more naturalistic form of a film. This finding raises questions about the place of films and written vignettes in future MHL research.  相似文献

Sequential multiple assignment randomized trials (SMARTs) are a useful and increasingly popular approach for gathering information to inform the construction of adaptive interventions to treat psychological and behavioral health conditions. Until recently, analysis methods for data from SMART designs considered only a single measurement of the outcome of interest when comparing the efficacy of adaptive interventions. Lu et al. proposed a method for considering repeated outcome measurements to incorporate information about the longitudinal trajectory of change. While their proposed method can be applied to many kinds of outcome variables, they focused mainly on linear models for normally distributed outcomes. Practical guidelines and extensions are required to implement this methodology with other types of repeated outcome measures common in behavioral research. In this article, we discuss implementation of this method with repeated binary outcomes. We explain how to compare adaptive interventions in terms of various summaries of repeated binary outcome measures, including average outcome (area under the curve) and delayed effects. The method is illustrated using an empirical example from a SMART study to develop an adaptive intervention for engaging alcohol- and cocaine-dependent patients in treatment. Monte Carlo simulations are provided to demonstrate the good performance of the proposed technique.  相似文献

Whereas capture experiments typically repeat a single task many times, real world cognition is characterized by frequent switching. Lien, Ruthruff, and Johnston (2010) reported that the attentional control system can rapidly and fully switch between different search settings (e.g., red to green), with no carryover and no intertrial priming. The present study examined whether this impressive flexibility is possible even when the switch is not between different features along the same dimension, but between mutually incompatible search modes. On each trial, participants were prompted to find and identify the letter that was in a specific colour (feature search mode) or was uniquely coloured (singleton search mode). Within each block, search mode was either pure or mixed; the mixed blocks contained a fixed AABB search sequence (singleton-singleton-feature-feature) in Experiment 1 and a random sequence in Experiment 2. The target display was preceded by a noninformative cue display containing a nontarget colour singleton. In pure feature search blocks, these irrelevant singleton cues were generally unable to capture attention, replicating previous findings of “contingent capture”. In mixed blocks, however, irrelevant colour singletons captured attention on feature search trials. This breakdown indicates a limitation in the sharpness of attentional control following mode switches, which might be common in the real world.  相似文献

The present study examined the influence of perfectionism and religious motivation on help-seeking and attitudes towards mental health services (ATMHS) in a Latter-Day Saint sample of 119 undergraduates. Increased levels of perfectionism significantly predicted more negative ATMHS. Higher intrinsic religious motivation was significantly and positively related to help-seeking from religious sources, but not from mental health professionals. Intrinsic religious motivation was also related to perfectionism, but only for adaptive subscales. The implications for focusing utilisation interventions towards religious populations are discussed.  相似文献

This study examined associations among resource loss, religiousness (including general religiousness, religious comfort, and religious strain), posttraumatic growth (PTG), and physical and mental health among a sample of Mississippi university students soon after Hurricane Katrina hit the Gulf coast in 2005. Resource loss was negatively associated with health, but positively associated with PTG. Religious comfort was associated with positive outcomes, and religious strain was associated with negative outcomes. Religious comfort buffered the negative effects of resource loss on emotional health. Ancillary analyses indicated that associations between resource loss and health were mediated by religious strain. Implications of this research are described for mental health practitioners engaged in disaster recovery work.  相似文献

Are adults’ decisions to use direct memory retrieval for simple addition influenced by the familiarity of problem operands? We manipulated the familiarity of a subset of operands by having adults repeatedly practise specific additions (two+five=?; Experiment 1) or magnitude comparisons (two five, choose the larger; Experiment 2). Both experiments provided evidence that pre-exposure to single-digit operands increased reported use of direct retrieval for new combinations of the familiarised operands. RT and error patterns across experiments also supported the conclusion that increased use of retrieval facilitated performance. These results show that operand familiarity potentially plays a significant role in adults’ strategy choices for simple addition.  相似文献

Some models of memory for arithmetic facts (e.g., 5+2=7, 6×7=42) assume that only the max-left order is stored in memory (e.g., 5+2=7 is stored but not 2+5=7). These models further assume an initial comparison of the two operands so that either operand order (5+2 or 2+5) can be mapped to the common internal representation. We sought evidence of number comparison in simple addition and multiplication by manipulating size congruity. In number comparison tasks, performance costs occur when the physical and numerical size of numerals are incongruent (8 3) relative to when they are congruent (8 3). Sixty-four volunteers completed a number comparison task, an addition task, and a multiplication task with both size congruent and size incongruent stimuli. The comparison task demonstrated that our stimuli were capable of producing robust size congruity and split effects. In the addition and multiplication task, however, we were unable to detect any of the RT signatures of comparison or reordering processes despite ample statistical power: Specifically, there was no evidence of size congruity, split, or order effects in either the addition or multiplication data. We conclude that our participants did not routinely engage a comparison operation and did not consistently reorder the operands to a preferred orientation.  相似文献

Miller and Paredes (1990) found that both children's and adults' performance of simple addition and multiplication tested in mixed-operation blocks was slower and more susceptible to operation errors (e.g., 6 + 2=12 or 6×2=8) compared to pure-operation blocks; but mixed-operation costs were greater for addition than for multiplication. We pursued the source of these effects in adults (n=96) by examining effects of operation switching and cueing. We replicated the asymmetrical costs of mixing addition and multiplication and demonstrated that these owed, in part, to asymmetrical task switching costs. Operation foreknowledge (a visual cue appearing 2 s before the problem) moderated both mixing and switch costs. This suggests that an asymmetry between addition and multiplication in the utility of preparation contributed to asymmetric mixing costs. Miller and Paredes proposed that the asymmetric costs of mixing operations observed in adults echoed an asymmetry developed in childhood when multiplication is initially learned. This might be correct, but our results raise the possibility that the asymmetry reflects operation-specific costs and interference effects that arise during the experiment.  相似文献
