老年人智力与年龄关系研究述评

介绍关于老年人智力发展的三种理论观点，以及影响老年人智力发展的因素。讨论了三种常见的研究方法。最后，指出了当前老年人智力研究领域中存在的一些问题，并对将来的研究进行了展望。     

Photograph method fosters direct access to second-language word meaning: Direct evidence from a word-picture matching task

This experiment was designed to investigate conceptual links directly through a word–picture matching task in children. Participants were asked to indicate between two pictures the one depicting the same concept as the newly learned L2 word (target). One of the two pictures was the target, while the other was either semantically related to it or was unrelated. To investigate whether learning methods modulate L2 word processing, two learning methods were compared: an L2-photograph method and an L1-L2 method. Results showed a semantic interference effect only with the L2-photograph method: Children responded more slowly in the related condition than in the unrelated one. The learning method modulated L2 word processing and L2 word meaning was not necessarily accessed through L1 mediation in the first steps of learning. The method used paves the way for the direct investigation of conceptual links.     

Low-literates’ support needs for societal participation learning: Empirical grounding of theory- and model-based design

Specialized learning support software can address the low societal participation of low-literate Dutch citizens. We use the situated Cognitive Engineering method to iteratively create a design specification for the envisioned system VESSEL: a Virtual Environment to Support the Societal participation Education of Low-literates. An initial high-level specification for this system is refined by incorporating the societal participation experiences of low-literate citizens into the design. In two series of user studies, the participant workshop and cultural probe methods were used with 23 low-literate participants. The Grounded Theory method was used to process the rich user data from these studies into the Societal Participation Experience of Low-Literates (SPELL) model. Using this experience model, the existing VESSEL specification was refined: requirements were empirically situated in the daily practice of low-literate societal participation, and new claims were written to explicate the learning effectiveness of the proposed VESSEL system. In conclusion, this study provides a comprehensive, theoretically and empirically grounded set of requirements and claims for the proposed VESSEL system, as well as the underlying SPELL model, which captures the societal participation experiences of low-literates citizens. The research methods used in this study are shown to be effective for requirements engineering with low-literate users.     

Asian American Female College Students' Subjective Femininity Conceptualizations: Using a Mixed‐Methods Approach

This mixed‐methods study explored 184 Asian American female college students' subjective femininity conceptualizations and their associations with family conflict. A direct content analysis of responses identified 5 categories of subjective femininity conceptualizations: model minority, physical attributes, traditional femininity, subordinate roles, and modern femininity. Conceptualizations of subordinate roles were positively related to intensity of family conflict. Interdependent self‐construal moderated the relationship between subjective conceptualizations of subordinate roles, modern femininity, and intensity of family conflict. Clinical implications of these findings are discussed. Este estudio de métodos combinados exploró las conceptualizaciones subjetivas de feminidad y sus asociaciones con conflictos familiares entre 184 estudiantes universitarias asiático‐americanas. Un análisis directo del contenido de las respuestas identificó 5 categorías de conceptualizaciones subjetivas de feminidad: modelo de minoría, atributos físicos, feminidad tradicional, roles subordinados y feminidad moderna. Las conceptualizaciones de roles subordinados se relacionaron de forma positiva con la intensidad de los conflictos familiares. La autoconstrucción interdependiente moderó la relación entre las conceptualizaciones subjetivas de roles subordinados, la feminidad moderna y la intensidad de los conflictos familiares. Se discuten las implicaciones clínicas de estos hallazgos.     

Stopping Rules for Computer Adaptive Testing When Item Banks Have Nonuniform Information

The standard error (SE) stopping rule, which terminates a computer adaptive test (CAT) when the SE is less than a threshold, is effective when there are informative questions for all trait levels. However, in domains such as patient-reported outcomes, the items in a bank might all target one end of the trait continuum (e.g., negative symptoms), and the bank may lack depth for many individuals. In such cases, the predicted standard error reduction (PSER) stopping rule will stop the CAT even if the SE threshold has not been reached and can avoid administering excessive questions that provide little additional information. By tuning the parameters of the PSER algorithm, a practitioner can specify a desired tradeoff between accuracy and efficiency. Using simulated data for the Patient-Reported Outcomes Measurement Information System Anxiety and Physical Function banks, we demonstrate that these parameters can substantially impact CAT performance. When the parameters were optimally tuned, the PSER stopping rule was found to outperform the SE stopping rule overall, particularly for individuals not targeted by the bank, and presented roughly the same number of items across the trait continuum. Therefore, the PSER stopping rule provides an effective method for balancing the precision and efficiency of a CAT.
