In immediate serial recall, high‐frequency words are better recalled than low‐frequency words. A prevalent interpretation of this effect suggests that, at the point of recall, degraded representations undergo a reconstruction process calling upon long‐term knowledge of the to‐be‐remembered items. Recently, Stuart and Hulme () following Deese (), suggested that high‐frequency items are better recalled due to their better long‐term associative links. Their results revealed that a familiarisation procedure involving repeated presentations of the to‐be‐remembered items in pairs abolished the usual frequency effect. In the experiment reported here, an alternative interpretation of this result is examined. Prior to the memory task, subjects received either no familiarisation, item familiarisation, or pair familiarisation. Both item and pair familiarisation improved the item recall of low‐frequency items to the same extent, suggesting that increased familiarity can account for the co‐occurrence effect.  相似文献

Research on prayer and posttraumatic growth (PTG) indicates that those who pray report more PTG. Research is beginning to identify which types of prayer may be operating in this relationship. We sought to identify specific prayer functions related to PTG while considering differences due to the types of trauma experienced. Participants were trauma survivors from diverse, Midwestern Christian churches (N = 327). Participants completed questionnaires assessing trauma history, prayer coping functions, and PTG. Multiple linear regression analyses found that praying for calm and focus was independently related to higher levels of PTG. When considering all variables in the model, the relationship between prayer for calm and focus and PTG was not significant for those whose most significant trauma was interpersonal in nature, but significant for those with noninterpersonal trauma.  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

ABSTRACT

This qualitative study focuses on the ways in which existential themes were understood and addressed in therapeutic relationships with patients who had attempted suicide. Health care professionals (HCP) from Norway specialist healthcare participated in focus groups. The interviews were transcribed and analysed by systematic text-condensation through a four-step procedure. We found that the HCPs emphasised the context-specific functions of their departments. They considered these conversations essential but demanding. They indicated existential themes of hope/hopelessness, loneliness, meaning, life/death, shame, religion and suicide. The HCPs’ understandings of themes deemed to be existential and how they should be addressed were primarily based on clinical experience. This appeared to exacerbate the pressure on their personal involvement, leading to the question of whether patients’ existential needs are tackled or instead disappear into a conversational vacuum. The study suggests that HCPs' professional competence of existential themes pertaining to patients at suicide risk needs to be strengthened.  相似文献

The study explored and described the lived experiences of single mothers and described guidelines for psychiatric nurses to facilitate the mental health of single mothers subjected to aggression by their adolescent sons. Participants were a purposive sample of 8 (single mothers, aged between 40 and 50 years, 7 mothers were employed and 3 were professionally trained, 4 mothers were domestic workers and 1 earned living by selling vegetables). The mothers attended the outpatient department at the National Psychiatric Hospital in Swaziland because of being exposed to aggression by their adolescent sons and had adolescent sons living with them 6 months prior to as well as during the study. Data were collected using individual in-depth phenomenological interviews, direct observation and field notes. Analyses used thematic coding. Results reflected that single mothers experienced their adolescent sons as disrespectful and violent, they had negative experiences about their adolescent sons which resulted in anxiety related symptoms, they had negative experiences of self and experienced poor relationships with their neighbours. Guidelines concerning intra- and interpersonal challenges were formulated for the psychiatric nurse to facilitate the mental health of these mothers.  相似文献

Are individuals willing to intervene in public violence? Half a century of research on the “bystander effect” suggests that the more bystanders present at an emergency, the less likely each of them is to provide help. However, recent meta-analytical evidence questions whether this effect generalizes to violent emergencies. Besides the number of bystanders present, an alternative line of research suggests that pre-existing social relations between bystanders and conflict participants are important for explaining whether bystanders provide help. The current paper offers a rare comparison of both factors—social relations and the number of bystanders present—as predictors of bystander intervention in real-life violent emergencies. We systematically observed the behavior of 764 bystanders across 81 violent incidents recorded by surveillance cameras in Copenhagen, Denmark. Bystanders were sampled with a case–control design, their behavior was observed and coded, and the probability of intervention was estimated with multilevel regression analyses. The results confirm our predicted association between social relations and intervention. However, rather than the expected reversed bystander effect, we found a classical bystander effect, as bystanders were less likely to intervene with increasing bystander presence. The effect of social relations on intervention was larger in magnitude than the effect of the number of bystanders. We assess these findings in light of recent discussions about the influence of group size and social relations in human helping. Further, we discuss the utility of video data for the assessment of real-life bystander behavior.  相似文献

There has been much speculation regarding the influence of cultural norms on the acceptance and use of personnel selection testing. This study examined the cross‐level direct effects of four societal cultural variables (performance orientation, future orientation, uncertainty avoidance, and tightness–looseness) on selection practices of organisations in 23 countries. A total of 1,153 HR professionals responded to a survey regarding testing practices in hiring contexts. Overall, little evidence of a connection between cultural practices and selection practices emerged. Implications of these findings for personnel selection and cross‐cultural research as well as directions for future work in this area are described.  相似文献
