Simple and complex span tasks are widely thought to measure related but separable memory constructs. Recently, however, research
has demonstrated that simple and complex span tasks may tap, in part, the same construct because both similarly predict performance
on measures of fluid intelligence (Gf) when the number of items retrieved from secondary memory (SM) is equated (Unsworth
& Engle, Journal of Memory and Language 54:68–80 2006). Two studies (n = 105 and n = 152) evaluated whether retrieval from SM is influenced by individual differences in the use of encoding strategies during
span tasks. Results demonstrated that, after equating the number of items retrieved from SM, simple and complex span performance
similarly predicted Gf performance, but rates of effective strategy use did not mediate the span-Gf relationships. Moreover,
at the level of individual differences, effective strategy use was more highly related to complex span performance than to
simple span performance. Thus, even though individual differences in effective strategy use influenced span performance on
trials that required retrieval from SM, strategic behavior at encoding cannot account for the similarities between simple
and complex span tasks. 相似文献

The goal of this paper is to introduce community gardening as a promising method of furthering well-being and resilience on multiple levels: individual, social group, and natural environment. We examine empirical evidence for the benefits of gardening, and we advocate the development and testing of social ecological models of community resilience through examination of the impact of community gardens, especially in urban areas. The definition of community is extended beyond human social ties to include connections with other species and the earth itself, what Berry (1988) has called an Earth community. We discuss the potential contribution of an extensive network of community gardens to easing the global climate change crisis and address the role of community psychologists in community gardening research and policy-oriented action. 相似文献

Several studies have used the lexical decision task (LDT) with the Deese-Roediger-McDermott (DRM) false-memory paradigm to investigate whether long-term semantic priming (LTSP) occurs following presentation of lists of items (e.g., bed, dream, snore) for related non-presented lure words (e.g., sleep). However, results have been mixed, with some studies observing priming, whilst others have not. The present study had four goals: (i) to investigate the existence of LTSP in the LDT; (ii) to investigate effects of LTSP on standard effects of word frequency on LDT performance; (iii) to investigate the effect, if any, of word frequency on true and false recall; and (iv) to compare LDT performance with performance on a subsequent free-recall task. The findings showed (i) a significant effect of LTSP on LDT performance; (ii) no effect of LTSP on standard effects of word frequency on LDT performance; (iii) no effect of word frequency on either true or false free recall; and (iv) a significant relationship between LDT and free-recall performance. Implications of these findings for understanding LTSP and false memories are discussed. 相似文献

Psychological trauma in childhood has been shown to increase a variety of psychological disturbances and psychiatric disorders. Although evidence-based treatments for children who have been traumatized exist, they are infrequently used by clinicians treating children. The present paper describes the creation of the Treatment Collaborative for Traumatized Youth (TCTY) which is a statewide partnership in North Dakota designed to disseminate efficacious treatments for traumatized children and monitor outcomes across a broad, rural, geographic expanse. The paper reviews the dissemination strategy developed by the TCTY, reports outcomes regarding both clinicians and child participants, and highlights problems identified in the project and solutions that were generated. 相似文献

This study assessed whether infant-directed videos designed to promote parent-child interactions actually support such engagement. Parents watched videos from the Baby Einstein or the Sesame Beginnings series for 2 weeks at home with their 12- or 18-month-old infants. Baby Einstein encourages parents to label objects and actions; Sesame Beginnings models activities in which parents can engage with their children. A control group was not provided videos for home viewing. In laboratory sessions, parent-child interactions were recorded during free play without TV, during the presentation of one of the videos, and immediately after watching. During viewing, interactions decreased in quantity and quality across groups; however, parents used video content as a basis for interaction. Coviewing Sesame Beginnings at home was positively associated with quantity of parent-child interaction during the initial free-play session. Furthermore, the quantity and quality of interactions were greater immediately following viewing of Sesame Beginnings than with Baby Einstein. 相似文献

Individuals with highly active behavioral activation (BAS) motivational systems are at increased risk for disordered eating behaviors (Bijttebier et al. 2009). The current study examined gender differences in the relationship between motivational tendencies and disordered eating behaviors by administering self-report measures to a sample of 352 college undergraduate students from a Midwestern university in the United States. The goal-driven facet of BAS (BAS-Drive) was a stronger predictor of muscle development behaviors for men than for women. In addition, higher levels of BAS-Drive were associated with greater dietary restraint among males, but not among females. Findings from the current study suggest that gender plays an important role in the relationship between BAS-Drive tendencies and eating disorder behaviors. 相似文献

The mere-exposure literature has shown that familiar objects are preferred to novel objects. However, no work has definitively
shown that mere exposure can direct and facilitate approach movements. In Experiment 1, participants were shown stimuli and
were later re-exposed to them along with novel stimuli. Participants were directed to make an approach or avoidant motion
to each and response times were recorded. As predicted, participants were quicker to approach and slower to avoid familiar
relative to novel stimuli. In Experiment 2, participants were shown mere-exposed and novel symbols and were asked to “push”
or “pull” a joystick in response to each, based on their intuition. Extending Experiment 1’s findings, participants freely
selected an approach response more frequently for familiar compared to novel stimuli. Moreover, in this same experiment, familiar
stimuli were judged as more likeable than were novel stimuli, and participants’ liking for familiar stimuli correlated with
the frequency with which they were approached. Implications of these findings are discussed. 相似文献

Four studies used experimental and correlational methods to investigate the effect of a "partner-achievement goal," or a personal goal for a relationship partner's successful achievement. This goal led support providers to offer unhelpful support about how to play a computer game (Study 1). It also predicted poor achievement for dieting support recipients (Study 2). The effects of partner-achievement goals were moderated by recipient expectations of success and mediated by recipient effort. Recipients with low expectations of their own success requested that their provider partners with partner-achievement goals refrain from offering them support (Study 3); they also invested less time studying Latin grammar and learned fewer Latin words over one week (Study 4). Together, these findings highlight the unique behavioral consequences of partner-achievement goals for both members of a relationship. 相似文献

There are significant gaps in the literature regarding the behavioural consequences of health anxiety. Although past research indicates that health anxiety is associated with distinctive maladaptive behaviours, such as reassurance seeking, the relationship between health anxiety and wellness-related behaviours, such as physical activity, has not been adequately examined. Given that health anxiety is associated with excessive attempts to ensure health and avoid illness, health anxiety could be potentially related to extreme physical activity, known as exercise dependence. Using the cognitive behavioural model of health anxiety as a framework, this exploratory study investigated the relationships between health anxiety, exercise desire, physical activity, and exercise dependence.Undergraduate university students (n = 144) completed a battery of online measures. Results indicated that only the perceptual component of health anxiety, namely hypervigilance to somatic symptoms, was related to exercise desire and components of exercise dependence. Implications of the findings are discussed and future research avenues are explored. 相似文献
