A mixed-methods process evaluation of a goal management intervention for patients with polyarthritis
Roos Y. Arends Christina Bode Erik Taal Mart A.F.J. Van de Laar 《Psychology & health》2017,32(1):38-60
Process evaluations of newly developed interventions are necessary to identify effective and less effective intervention components. First aim of this study was to identify key components of a psychosocial goal management intervention from the perspective of participants, and second aim was to evaluate the intervention’s fidelity. A mixed-methods approach was applied to 24 interviews with participants post-intervention and 16 audio recordings of random training sessions. Participants experienced three key components: (1) the content, in which specific exercises helped to raise awareness and (intention to) change goal management behaviour, (2) person-focused approach, specifically, the nurse as trainer and personal fit of the approach, and (3) social mechanisms, including facilitating group processes and interpersonal processes. Adherence to the protocol by the trainers was high, while differences were found in the degree to which they were able to apply the intended collaborative approach and psychological communication skills. The applied design provided valuable insights into the processes that took place. Both the effects experienced by participants in relationship to the content, approach and social mechanisms as well as the strengths and weaknesses found with regard to fidelity provide insights that can inform the development and implementation of person-focused interventions. 相似文献

Adults automatically infer a person’s social disposition and future behavior based on the many properties they observe about how they look and sound. The goal of the current study is to explore the developmental origins of this bias. We tested whether 12-month-old infants automatically infer a character’s social disposition (e.g., whether they are likely to “help” or “hinder” another character’s goal) based on the sounds and visual features those characters display. Infants were habituated to 2 characters, 1 that possessed more positive properties (e.g., a soft, fluffy appearance and a happy-sounding laugh) or more negative properties (e.g., a sharp, pointy appearance and a deep, ominous laugh). During test trials, we observed that infants looked longer at events that involved characters engaging in social actions toward another that were inconsistent rather than consistent with the valence of how they looked and sounded during habituation. Two control conditions support the interpretation that infants’ responses were based on an inferred causal relationship between a character’s features and its disposition rather than on some noncausal associations between the positive and negative valences of the characteristics and actions. Together, these studies suggest that infants are biased to connect an agent’s audiovisual features to their social behavior. 相似文献

Across a variety of tasks, adults respond differently to syllables with multiple stress cues than to syllables with only one cue to stress. This series of experiments was designed to explore how infants and adults use partial stress as a cue to word boundaries. In the first experiment, 9-month-old infants treated syllables with only one cue to stress (spectral tilt) as a strong cue to word boundaries. The second experiment shows that whereas adults treat syllables with multiple cues to stress as word onsets, they do not consider syllables marked only by spectral tilt to be strong indicators of word boundaries. Thethird experiment shows that 1-year-old infants are more adultlike than 9-month-olds in their use of stress cues. Taken together, these results suggest a rapid development of stress cue knowledge in infancy, perhaps due to infants' experience with word segmentation. 相似文献

The preparation effect in task switching: Carryover of SOA 总被引:3,自引:0,他引:3
Altmann EM 《Memory & cognition》2004,32(1):153-163
A common finding in task-switching studies is switch preparation (commonly known as the preparation effect), in which a longer interval between task cue and trial stimulus (i.e., a longer stimulus onset asynchrony, or SOA) reduces the cost of switching to a different task. Three experiments link switch preparation to within-subjects manipulations of SOA. In Experiment 1, SOA was randomized within subjects, producing switch preparation that was more pronounced when the SOA switched from the previous trial than when the SOA repeated. In Experiment 2, SOA was blocked within subjects, producing switch preparation but not on the first block of trials. In Experiment 3, SOA was manipulated between subjects with sufficient statistical power to detect switch preparation, but the effect was absent. The results favor an encoding view of cognitive control, but show that any putative switching mechanism reacts lazily when exposed to only one SOA. 相似文献

The preparation effect in task switching is usually interpreted to mean that a switching process makes use of the interval between task-cue onset and trial-stimulus onset (the cue-stimulus interval, or CSI) to accomplish some of its work ahead of time. This study undermines the empirical basis for this interpretation and suggests that task activation, not task switching, is the functional process in cognitive control. Experiments 1 and 2 used an explicit cuing paradigm, and Experiments 3 and 4 used a variation in which the trial after a task cue was followed by several cueless trials, requiring retention of the cue in memory. Experiments 1 and 3 replicated the preparation effect on switch cost, and Experiments 2 and 4 showed that this effect vanishes when CSI is manipulated between subjects, leaving only a main effect of CSI when the task cue is a memory load. 相似文献

Three fear-conditioning experiments with rat subjects examined the effects of extinction in multiple contexts on a final relapse (renewal) effect that occurred when the extinguished fear cue was tested in a new context (Experiments 1 and 3) or in the context in which fear conditioning had first occurred (Experiment 2). Rats that received extinction in three contexts demonstrated more fear during extinction than rats that received the same number and temporal distribution of extinction trials in one context; extinction was partially lost with each context switch. Although extinction in multiple contexts thus had an impact on extinction behavior, it did not reduce the size of the final renewal effect. Fear during extinction was occasionally positively correlated with fear during final testing, but the two were never negatively correlated. The results suggest that extinction in multiple contexts does not necessarily weaken fear renewal, and that extinction procedures that generate high levels of responding in extinction do not necessarily make extinction learning less context-specific. 相似文献

The purpose of the current study was twofold: (a) to investigate if it was possible to train three different games (both as a leader and as a participant) to a child with developmental disabilities through interaction with 4 typically developing peers, and (b) to examine if correct responding would be maintained after the training was faded. A multiple probe design across three games was used. The results showed that the child learned both skills as a leader and as a participant in all three games, and that skills were maintained for a period of 3 weeks after the training had stopped. 相似文献

To investigate interpersonal theory, the authors examined the social behavior of 112 previously unacquainted male-female pairs collaborating on a joint task. Structural equation modeling analyses provided clear evidence of complementarity: In addition to trait affiliation and dominance both predicting situational behavior, each interaction partner's behavior influenced the other's in accordance with the theory, eliciting similar levels of affiliation and opposite levels of dominance. There were also clear biases related to participants' interpersonal traits: When behavior, as indexed by observers, was held constant, more trait affiliative participants tended to view themselves and their partner as warmer during the interaction; likewise, more trait dominant participants perceived themselves to act more dominantly than they actually did. Throughout, there were no sex differences. 相似文献

With the aim of reducing cognitive control in task switching to simpler processes, researchers have proposed in a series of recent studies that there is little more to switching tasks than switching cues. The present study addresses three questions concerning this reduction hypothesis. First, does switching cues account for all relevant variance associated with switching tasks? Second, how well does this hypothesis generalize beyond the experimental procedure from which it was developed? Third, how well does this new procedure preserve relevant measures such as task-switch cost? The answers (no; not very; not very) suggest that task switching does not reduce to cue switching. 相似文献
