The purpose of the current study was to examine the impact of item parameter drift (IPD) occurring in context questionnaires from an international large-scale assessment and determine the most appropriate way to address IPD. Focusing on the context of psychometric and educational research where scores from context questionnaires composed of polytomous items were employed for the classification of examinees, the current research investigated the impacts of IPD on the estimation of questionnaire scores and classification accuracy with five manipulated factors: the length of a questionnaire, the proportion of items exhibiting IPD, the direction and magnitude of IPD, and three decisions about IPD. The results indicated that the impact of IPD occurring in a short context questionnaire on the accuracy of score estimation and classification of examinees was substantial. The accuracy in classification considerably decreased especially at the lowest and highest categories of a trait. Unlike the recommendation from literature in educational testing, the current study demonstrated that keeping items exhibiting IPD and removing them only for transformation were appropriate when IPD occurred in relatively short context questionnaires. Using 2011 TIMSS data from Iran, an applied example demonstrated the application of provided guidance in making appropriate decisions about IPD. 相似文献

Two well documented but still neglected blind spots of often‐used study designs limit a researcher's ability to make inferences about psychological phenomenon. First, typical designs focus on effects of conditions at the group level and are not able to assess the extent to which effects characterize each participant in the study. This blind spot can lead to erroneous (or incomplete) conclusions about the effects of manipulations both for a given participant and at the group level. Second, commonly used research designs often use a limited sample of stimuli, constraining conclusions to the particular stimuli. This blind spot can lead to non‐replication when different stimuli are used. We propose that the Highly‐Repeated Within‐Person (HRWP) approach helps mitigate these limitations. Using a study on the effects of anti‐smoking messages, we illustrate how the HRWP approach helps alert researchers when the conclusions at the group level may not apply to all (or any) participant, quantifies the heterogeneity of effects of manipulations across people, and increases confidence regarding the generalizability of the effects. We discuss how the HRWP approach may help conceptualize issues of replicability in a new light. 相似文献

Chronic parental maltreatment has been associated with lower levels of interpersonal trust, and depriving environments have been shown to predict short‐sighted, risk‐averse decision‐making. The present study examined whether a circumscribed period of adverse care occurring only early in life was associated with biases in trust behavior. Fifty‐three post‐institutionalized (PI) youth, adopted internationally on average by 1 year of age, and 33 never‐institutionalized, non‐adopted youth (Mage = 12.9 years) played a trust game. Participants decided whether or not to share coins with a different anonymous peer in each trial with the potential to receive a larger number of coins in return. Trials were presented in blocks that varied in the degree to which the peers behaved in a trustworthy (reciprocal) or untrustworthy (non‐reciprocal) manner. A comparison condition consisted of a computerized lottery with the same choices and probabilistic risk as the peer trials. Non‐adopted comparison youth showed a tendency to share more with peers than to invest in the lottery and tended to maintain their level of sharing across trials despite experiencing trials in which peers failed to reciprocate. In contrast, PI children, particularly those who were adopted over 1 year of age, shared less with peers than they invested in the lottery and quickly adapted their sharing behavior to peers’ responses. These results suggest that PI youth were more mistrusting, more sensitive to both defection and reciprocation, and potentially more accurate in their trusting decisions than comparison youth. Results support the presence of a sensitive period for the development of trust in others, whereby conditions early in life may set long‐term biases in decision‐making. 相似文献

Although electronic devices may enhance the effectiveness of some behavioral interventions for children with autism spectrum disorders, such devices may also give rise to problem behavior such as repetitious button pressing (i.e., object stereotypy). Results of this study showed that a child with autism spectrum disorder only displayed high levels of object stereotypy on an iPad? when presses generated auditory output. Subsequently, results showed that when the participant used the iPad? without auditory output, his stereotypical behavior decreased and his manding for various items simultaneously increased. 相似文献

Functional communication training (FCT) is a procedure used to teach a communicative response that results in the same reinforcer found to maintain problem behavior. Previous research has demonstrated that high levels of problem behavior may be observed during FCT when reinforcing an existing response due to a history of reinforcement for both existing responses and problem behavior. This study compared the effects of reinforcing an existing and novel communicative response during FCT on the rate of problem behavior for two children diagnosed with autism. Additionally, we assessed preference for either the existing or novel response using a concurrent schedules arrangement. The results demonstrated that the existing and novel communication responses were associated with low levels of problem behavior for both participants. Also, both participants preferred the novel response. We conclude with a discussion of practical applications of the analysis and avenues for future research. 相似文献

We examined the effectiveness of intraverbal prompts to increase the number of divergent responses to categorical questions composed of compound stimuli (e.g., Name some red things) for a 6‐year‐old child with autism. The intraverbal prompts involved providing the function, feature, and class of the target responses. A multiple probe across behaviors design was used. Results indicated that the child's total number of divergent responses was increased and maintained during 2‐week follow‐up probe trials. Novel responses were observed across conditions. 相似文献

Distorted negative self-images and impressions appear to play a key role in maintaining Social Anxiety Disorder (SAD). In previous research, McManus et al. (2009) found that video feedback can help people undergoing cognitive therapy for SAD (CT-SAD) to develop a more realistic impression of how they appear to others, and this was associated with significant improvement in their social anxiety. In this paper we first present new data from 47 patients that confirms the value of video feedback. Ninety-eighty percent of the patients indicated that they came across more favorably than they had predicted after viewing a video of their social interactions. Significant reductions in social anxiety were observed during the following week and these reductions were larger than those observed after control periods. Comparison with our earlier data (McManus et al., 2009) suggests we may have improved the effectiveness of video feedback by refining and developing our procedures over time. The second part of the paper outlines our current strategies for maximizing the impact of video feedback. The strategies have evolved in order to help patients with SAD overcome a range of processing biases that could otherwise make it difficult for them to spot discrepancies between their negative self-imagery and the way they appear on video. 相似文献

This study is the first to expand the investigation of study-abroad risks to include a range of traumatic experiences for male and female students and to examine effects of institutional betrayal (i.e., an institution’s failure to prevent trauma or support survivors). In an online survey of 173 university students who had studied abroad, many respondents (45.44%, n = 79) reported exposure to at least 1 traumatic experience while abroad, most frequently natural disasters, sexual assault, and unwanted sexual experiences. Of students exposed to potentially traumatic events, more than one third (35.44%, n = 28) also reported at least 1 form of related institutional betrayal, which uniquely correlated with posttraumatic distress in some participants, when controlling for lifetime trauma history. 相似文献

Over the last decade authors have critiqued the hegemonic structures that perpetuate knowledge hierarchies in the dominant research regimes that foster privilege across the globe. The authors in this article use collective biography to reflectively engage with knowledge production in the academy. They explore the nature of prudentia as an affective shame that surfaces through reflexive engagement with the politics of research cultures. Collective biography, as a ‘grassroots’ form of deliberate and collaborative interrogation, produces insight from ‘difficult knowledge’ that sheds light on power imbalance in North/South relations in research practice. In endeavouring to grapple with Southern Theory, the authors surface ‘unwelcome truths’. These disquieting ruptures reveal the power of prudentia for academics who are desirous to unsettle the complacency of Northern assumptions as they engage in an ongoing struggle with doing Southern Theory. 相似文献
