Temporal order psychometric functions based on confidence-rating data

Psychophysical tasks involving confidence judgments allow the simultaneous generation of a family of psychometric functions. Sternberg, Knoll, and Mallows (1975) have demonstrated the power of the multiple-function approach in evaluating models concerned with specifying the source of errors in judgments of simultaneity and temporal order. In the present paper, data from a temporal order task requiring confidence ratings are examined, and a number of models for successiveness and order judgments evaluated.

     

Some aspects of perceptual coding of duration in visual duration discrimination

Data are presented which indicate two major differences between duration discrimination performance and discrimination performance usually observed in other psychophysical tasks. A decrement in duration discrimination performance with increasing temporal delays between the presentation of two successive stimuli was not found, and the usual difference in level of performance between forced-choice and single-stimulus tasks was not observed. The time-order error in duration discrimination is also discussed.     

Feature Statistics Modulate the Activation of Meaning During Spoken Word Processing

Understanding spoken words involves a rapid mapping from speech to conceptual representations. One distributed feature‐based conceptual account assumes that the statistical characteristics of concepts’ features—the number of concepts they occur in (distinctiveness/sharedness) and likelihood of co‐occurrence (correlational strength)—determine conceptual activation. To test these claims, we investigated the role of distinctiveness/sharedness and correlational strength in speech‐to‐meaning mapping, using a lexical decision task and computational simulations. Responses were faster for concepts with higher sharedness, suggesting that shared features are facilitatory in tasks like lexical decision that require access to them. Correlational strength facilitated responses for slower participants, suggesting a time‐sensitive co‐occurrence‐driven settling mechanism. The computational simulation showed similar effects, with early effects of shared features and later effects of correlational strength. These results support a general‐to‐specific account of conceptual processing, whereby early activation of shared features is followed by the gradual emergence of a specific target representation.     

No Sissy Boys Here: A Content Analysis of the Representation of Masculinity in Elementary School Reading Textbooks

In this study, we investigate the portrayal of gender characteristics in elementary school reading textbooks. Over the past 25 years, most of the research on textbooks has focused on female roles and characteristics. In this research, we focus particularly on how males are portrayed. Using an evaluative instrument based on the Bem Sex Role Inventory, we examine first, third, and fifth grade literature textbooks. In particular, we analyze traits pertaining to masculine and feminine stereotypes. Our results show that despite publisher's guidelines and Title IX, males are still primarily portrayed in a stereotypical light. Males are overwhelming shown to be aggressive, argumentative, and competitive.     

Field and observer viewpoint in remember-know memories of personal childhood events

This experiment examined the viewpoint and other phenomenal characteristics of childhood memories based on both personal recollections and self-knowledge. Participants were asked to provide examples of remember, know, and uncertain memories, and to rate each memory on a number of dimensions. Remembered events were generally viewed from a field perspective, while known-about events were generally viewed from an observer perspective. In line with earlier research, remembered events received the highest ratings for sensory and contextual detail, emotional content, and memory accuracy, while known-about events were given the lowest ratings. The results are discussed with reference to their possible implications for memory recovery or enhancement techniques that ask people to adopt a different viewpoint. Consideration is given as to whether a switch to a field perspective might encourage the acceptance of suggested details or events.     

Perceived Risks and Benefits in a Text Message Study of Substance Abuse and Sexual Behavior

To inform ethical procedures for human subjects research using mobile health (mHealth), we examined perceived risks and benefits of study participation among emerging adults (N = 54) with drug use who completed text message assessments of substance use and sexual behaviors. Most participants reported comfort with participation and some reported perceived benefits, such as improved relationships. Perceived risks were infrequently reported, including negative emotions and legal or financial concerns. In conclusion, participants from a vulnerable population reported few perceived harms of participation in longitudinal mHealth assessments of sensitive behaviors. Researchers should continue characterizing participants’ perspectives on ethical aspects of mHealth research.     

A Review of “Trauma and Human Existence: Autobiographical,Psychoanalytic and Philosophical Reflections”

Abstract

The author sets out to locate Bion's model of the mind within the developmental history of psychoanalysis, from Freud to Klein to Bion, using biographical material and clinical case examples, to illustrate Bion's concepts of container/contained, his understanding and use of projective identification, his extension of the use of the countertransference, and his differentiation between the psychotic and non-psychotic aspects of the mind. Links, and attacks against linking are discussed, as well as Bion's thoughts about learning versus knowing, being versus becoming and his emphasis on the essential importance of the development of the capacity to think.     

数学应用题中语言成分模型的构建—— 多元随机效应项目反应理论模型的运用

数学应用题中的语言成分可能对被试问题解决过程产生复杂影响。通常, 这种影响对所有被试并非完全一致, 而是具体数学题目特征与特定被试的认知特性之间交互作用的结果。本研究采用多元随机效应项目反应理论模型的建模方法, 分析了数学应用题中语言成分对问题解决过程的影响。该方法的优势在于它不仅分析了语言成分对数学问题解决过程的平均效应, 同时给出了相应的随机效应, 揭示了相应成分对不同个体问题解决过程的具体影响程度。结果表明, 较难的项目倾向于单词更多, 命题密度更高, 要求对图/表信息进行编码和转译, 或者根据问题表述生成数学公式。项目命题密度影响效应存在着显著的个别差异。项目命题密度对能力较低的被试的影响高于对能力较高的被试的影响。
