This study explores conceptualisations of same‐ versus different‐sex infidelity in the context of a heterosexual marriage using story completion. A convenience sample of 57 female and male participants completed one of four versions of a story stem featuring a husband who is either emotionally or sexually unfaithful with a woman or a man. A social constructionist thematic analysis found that same‐sex infidelity was conceptualised as the ‘worst case scenario’ and was underpinned by a heteronormative framing of repressed homosexuality. By contrast, heterosexual infidelity was understood in terms of relational deficits and the wife assuming responsibility for these. Overall, the analysis shows that in making sense of same‐sex and heterosexual infidelity, the participants drew on familiar discourses of sexuality and gender, suggesting that despite social psychological theorising related to sexual fluidity, essentialist ideas remain firmly in place. Methodologically, the study demonstrates the usefulness of a rarely used tool—the story completion task—for accessing socio‐cultural discourses and dominant meanings surrounding a particular topic.

There are cells in our motor cortex that fire both when we perform and when we observe similar actions. It has been suggested that these perceptual‐motor couplings in the brain develop through associative learning during correlated sensorimotor experience. Although studies with adult participants have provided support for this hypothesis, there is no direct evidence that associative learning also underlies the initial formation of perceptual–motor couplings in the developing brain. With the present study we addressed this question by manipulating infants’ opportunities to associate the visual and motor representation of a novel action, and by investigating how this influenced their sensorimotor cortex activation when they observed this action performed by others. Pre‐walking 7–9‐month‐old infants performed stepping movements on an infant treadmill while they either observed their own real‐time leg movements (Contingent group) or the previously recorded leg movements of another infant (Non‐contingent control group). Infants in a second control group did not perform any steps and only received visual experience with the stepping actions. Before and after the training period we measured infants’ sensorimotor alpha suppression, as an index of sensorimotor cortex activation, while they watched videos of other infants’ stepping actions. While we did not find greater sensorimotor alpha suppression following training in the Contingent group as a whole, we nevertheless found that the strength of the visuomotor contingency experienced during training predicted the amount of sensorimotor alpha suppression at post‐test in this group. We did not find any effects of motor experience alone. These results suggest that the development of perceptual–motor couplings in the infant brain is likely to be supported by associative learning during correlated visuomotor experience.  相似文献

Psittacines are generally considered to possess cognitive abilities comparable to those of primates. Most psittacine research has evaluated performance on standardized complex cognition tasks, but studies of basic cognitive processes are limited. We tested orange-winged Amazon parrots (Amazona amazonica) on a spatial foraging assessment, the Hamilton search task. This task is a standardized test used in human and non-human primate studies. It has multiple phases, which require trial and error learning, learning set breaking, and spatial memory. We investigated search strategies used to complete the task, cognitive flexibility, and long-term memory for the task. We also assessed the effects of individual strength of motor lateralization (foot preference) and sex on task performance. Almost all (92 %) of the parrots acquired the task. All had significant foot preferences, with 69 % preferring their left foot, and showed side preferences contralateral to their preferred limb during location selection. The parrots were able to alter their search strategies when reward contingencies changed, demonstrating cognitive flexibility. They were also able to remember the task over a 6-month period. Lateralization had a significant influence on learning set acquisition but no effect on cognitive flexibility. There were no sex differences. To our knowledge, this is the first cognitive study using this particular species and one of the few studies of cognitive abilities in any Neotropical parrot species.  相似文献

A key challenge for positive psychology interventions is promoting sustained engagement to improve long-term outcomes. One way to increase engagement is to introduce variety to reduce hedonic adaptation. Here, we propose supplementing intervention prompts with items from a person’s social media archive to add variety. Through a one-week pilot study of six positive psychology activities via a Facebook application, we explore whether Facebook content is useful to keep people engaged in activities and what attributes of content make it most useful. A total of 260 participants used our application, and analysis of usage showed that displaying content is engaging. By looking at which content was marked as useful by participants, we find that useful content is in itself meaningful and engaging (photos, longer texts, and content about close friends). We also find that certain intervention activities are more engaging and better suited for making use of Facebook content than others.  相似文献

Inspiration is a concept of longstanding interest in diverse areas of academia, but it has only recently become the subject of rigorous scientific investigation. In this article, we review the emerging scientific literature on inspiration, with a focus on both theory and findings. First, we present a general definition of inspiration based on an integrative literature review, and we outline approaches to differentiating the general inspiration construct into specific types. Second, we review the literature on construct validity. Third, we present substantive theory and findings, with an emphasis on the role of inspiration in promoting attainment of elusive goods, such as creativity, productivity, and happiness. Finally, we respond to frequent questions and misconceptions about inspiration, and we offer recommendations about how to promote inspiration in others or oneself.  相似文献

This paper focuses on the divergence behaviour of the successive geometric mean (SGM) method used to generate pairwise comparison matrices while solving a multiple stage, multiple objective (MSMO) optimization problem. The SGM method can be used in the matrix generation phase of our three‐phase methodology to obtain pairwise comparison matrix at each stage of an MSMO optimization problem, which can be subsequently used to obtain the weight vector at the corresponding stage. The weight vectors across the stages can be used to convert an MSMO problem into a multiple stage, single objective (MSSO) problem, which can be solved using dynamic programming‐based approaches. To obtain a practical set of non‐dominated solutions (also referred to as Pareto optimal solutions) to the MSMO optimization problem, it is important to use a solution approach that has the potential to allow for a better exploration of the Pareto optimal solution space. To accomplish a more exhaustive exploration of the Pareto optimal solution space, the weight vectors that are used to scalarize the MSMO optimization problem into its corresponding MSSO optimization problem should vary across the stages. Distinct weight vectors across the stages are tied directly with distinct pairwise comparison matrices across the stages. A pairwise comparison matrix generation method is said to diverge if it can generate distinct pairwise comparison matrices across the stages of an MSMO optimization problem. In this paper, we demonstrate the SGM method's divergence behaviour when the three‐phase methodology is used in conjunction with an augmented high‐dimensional, continuous‐state stochastic dynamic programming method to solve a large‐scale MSMO optimization problem.

We examined co-parenting alliance based on information provided by 57 incarcerated parents and their corresponding child caregivers who took part in the Messages Project, in which incarcerated parents video recorded greetings to children that were then mailed home. We assessed perceptions of co-parenting alliance, measured by the Parenting Alliance Measure, and levels of child contact from both parents and caregivers. We also observed expressions of positive and negative attitudes that prisoners expressed regarding the home caregiver during the video recording. Incarcerated parents reported more frequent phone contact with children and more frequent letter-writing to children than did home caregivers. Incarcerated parents likewise reported higher levels of co-parenting alliance with the home caregiver in comparison to the assessment of co-parenting alliance reported by the home caregiver. Among children observing the video recorded message, a more positive co-parenting alliance between their parent and home caregiver was associated with increased positive mood. More frequent displays of negative attitudes toward caregivers during the recordings were associated with more negative mood indicators among children. Results suggest the importance of a strong co-parenting alliance between incarcerated parents and home caregivers, but imply that incarcerated parents may have a more optimistic view of their connection home than is the case for collaborating caregivers.  相似文献

In an eye movement experiment, we assessed the performance of young (18–30 years) and older (65 + years) adult readers when sentences contained conventional interword spaces, when interword spaces were removed, or when interword spaces were replaced by nonlinguistic symbols. The replacement symbol was either a closed square (■) that provided a salient (low-spatial-frequency) cue to word boundaries, or an open square (□) that provided a less salient cue and included features (vertical and horizontal lines) similar to those found in letters. Removing or replacing interword spaces slowed reading times and impaired normal eye movement behavior for both age groups. However, this disruption was greater for the older readers, particularly when the replacement symbol did not provide a salient cue as to word boundaries. Specific influences of this manipulation on word identification during reading were assessed by examining eye movements for a high- or low-frequency target word in each sentence. Standard word frequency effects were obtained for both age groups when text was spaced normally, and although the word frequency effect was larger when spaces were removed or filled, the increases were similar across age groups. Therefore, whereas older adults’ normal eye movements were substantially disrupted when text lacked conventional interword spaces, the process of lexical access associated with the word frequency effect was no more difficult for older than for young adults. The indication, therefore, is that although older adults struggle from the loss of conventional cues to word boundaries, this is not due to additional difficulties in word recognition.  相似文献
