Linking sight and sound: fMRI evidence of primary auditory cortex activation during visual word recognition

We describe two studies that used repetition priming paradigms to investigate brain activity during the reading of single words. Functional magnetic resonance images were collected during a visual lexical decision task in which nonword stimuli were manipulated with regard to phonological properties and compared to genuine English words. We observed a region in left-hemisphere primary auditory cortex linked to a repetition priming effect. The priming effect activity was observed only for stimuli that sound like known words; moreover, this region was sensitive to strategic task differences. Thus, a brain region involved in the most basic aspects of auditory processing appears to be engaged in reading even when there is no environmental oral or auditory component.     

Is Disciplinary Culture a Moderator Between Materialism and Subjective Well-being? A Three-Wave Longitudinal Study

To clarify the influence of disciplinary culture on the materialism–subjective well-being (SWB) relationship, as well as the relationship between changes in materialism and changes in SWB, the current longitudinal study tracked the levels of materialism and SWB among first-year undergraduates for 12 months. A total of 218 participants from a congruent disciplinary culture (i.e., business school) and 210 participants from an incongruent disciplinary culture (i.e., engineering school) provided ratings on the Material Values Scale, the Satisfaction with Life Scale, and the Positive and Negative Affect Schedule in three waves. The following results were obtained: (1) the interaction effect of disciplinary culture and time was significant. In Wave 3, the level of materialism in business school was significantly higher than that in engineering school, but this difference was not found in Waves 1 and 2; (2) the negative relationship between materialism and SWB remained stable over time and was not moderated by disciplinary culture. Moreover, disciplinary culture did not moderate the relationship between changes in materialism and changes in SWB. The above findings indicate that disciplinary culture influences the development of materialism but not the materialism–SWB relationship in the long term.     

Making Sense of Climate Change: How Story Frames Shape Cognition

In 2006, Adam J. Berinsky and Donald R. Kinder published findings in the Journal of Politics that demonstrated that framing news as a story influences how individuals cognitively organize concepts and information. The study presented here moves forward in this tradition. This research combines samples obtained in the springs of 2009 and 2010 while conducting online experiments. In these experiments, slightly over 2,000 respondents are asked to organize concepts presented in one of three culturally nuanced stories about climate change or where information is presented as a list. Hierarchical cluster analysis indicates that when respondents are exposed to culturally congruent stories, respondent organizational patterns are more likely to mirror the story. We discuss the implications of these findings.     

Detecting Curvilinear Relationships: A Comparison of Scoring Approaches Based on Different Item Response Models

There is a growing use of noncognitive assessments around the world, and recent research has posited an ideal point response process underlying such measures. A critical issue is whether the typical use of dominance approaches (e.g., average scores, factor analysis, and the Samejima's graded response model) in scoring such measures is adequate. This study examined the performance of an ideal point scoring approach (e.g., the generalized graded unfolding model) as compared to the typical dominance scoring approaches in detecting curvilinear relationships between scored trait and external variable. Simulation results showed that when data followed the ideal point model, the ideal point approach generally exhibited more power and provided more accurate estimates of curvilinear effects than the dominance approaches. No substantial difference was found between ideal point and dominance scoring approaches in terms of Type I error rate and bias across different sample sizes and scale lengths, although skewness in the distribution of trait and external variable can potentially reduce statistical power. For dominance data, the ideal point scoring approach exhibited convergence problems in most conditions and failed to perform as well as the dominance scoring approaches. Practical implications for scoring responses to Likert-type surveys to examine curvilinear effects are discussed.     

青少年公正世界信念对抑郁的影响:感恩和自尊的序列中介作用

为探讨青少年公正世界信念与抑郁的关系,以及感恩和自尊在二者关系中的作用机制,采用公正世界信念问卷(BJW)、感恩问卷(GQ-6)、自尊量表(SES)和流调中心用抑郁量表(CES-D)对1049名高中学生进行调查。结果发现:(1)青少年公正世界信念、感恩和自尊两两之间呈显著正相关,且三者均与抑郁呈显著负相关。(2)青少年公正世界信念通过感恩和自尊的中介作用对抑郁产生影响,且该中介效应包含了三条中介路径——感恩的简单中介效应,自尊的简单中介效应,以及感恩→自尊的链式中介作用。研究结果揭示了青少年公正世界信念对抑郁产生影响的内部心理机制,为引导青少年更好地利用公正世界信念提升感恩和自尊的水平以及更好地促进心理健康发展提供了有益建议。     

Bayesian active probabilistic classification for psychometric field estimation

Psychometric functions are typically estimated by fitting a parametric model to categorical subject responses. Procedures to estimate unidimensional psychometric functions (i.e., psychometric curves) have been subjected to the most research, with modern adaptive methods capable of quickly obtaining accurate estimates. These capabilities have been extended to some multidimensional psychometric functions (i.e., psychometric fields) that are easily parameterizable, but flexible procedures for general psychometric field estimation are lacking. This study introduces a nonparametric Bayesian psychometric field estimator operating on subject queries sequentially selected to improve the estimate in some targeted way. This estimator implements probabilistic classification using Gaussian processes trained by active learning. The accuracy and efficiency of two different actively sampled estimators were compared to two non-actively sampled estimators for simulations of one of the simplest psychometric fields in common use: the pure-tone audiogram. The actively sampled methods achieved estimate accuracy equivalent to the non-actively sampled methods with fewer observations. This trend held for a variety of audiogram phenotypes representative of the range of human auditory perception. Gaussian process classification is a general estimation procedure capable of extending to multiple input variables and response classes. Its success with a two-dimensional psychometric field informed by binary subject responses holds great promise for extension to complex perceptual models currently inaccessible to practical estimation.

     

Attitude Towards Persons with Intellectual Disability Scale: Further Development

The purpose of this study is to revise and further develop an attitude towards person with intellectual disability scale (APIDs). The further development of this scale was mainly based on Community Living Attitude Scale (CLAS) and Attitude towards Intellectual Disability Questionnaire (ATTID). The study examined the psychometric properties of the proposed measuring instrument in terms of its factorial validity and internal consistency reliability. The confirmatory factor analysis showed that the proposed five-factor model did not fit the data well. Exploratory factorial analysis was then conducted to re-examine the structure. The results suggested a three-factor structure, i.e. sociality, capacity, and protection. The internal consistency reliability was good for sociality and capacity but needs further improvement for protection. The cultural and social landscape within a population affects the factorial structure an attitude scale. The use of APIDs was also discussed.

The Satisfaction with Life Scale in Adolescent Samples: Measurement Invariance across 24 Countries and Regions,Age, and Gender

Measurement of adolescent life satisfaction across cultures has not received much attention in previous empirical research. The present study evaluated measurement invariance of the Satisfaction with Life Scale (SWLS) among adolescents in 24 countries and regions (N = 22,710; age range = 13–19 years; 53% female). A single-factor model with residual covariance between a pair of items tapping past life satisfaction fitted well in 19 countries and regions and showed a partial metric invariance. In a subset of nine countries and regions, partial scalar invariance was supported. Partial metric invariance across all 24 countries and regions was achieved when custom model modifications in five countries and regions were included. Three SWLS items showed evidence of noninvariance across cultures. The measurement model was found to operate similarly across gender and age. Our findings suggest that caution is needed when using the SWLS for measuring life satisfaction among adolescents from different cultures.
