Aging and Information Technology Use: Potential and Barriers

ABSTRACT— Why are older adults reluctant to adopt new technology, such as the Internet, given its potential to improve the quality of their lives? We review evidence indicating that attitudes and abilities are among the most powerful predictors of technology use. We conclude that normative age-related changes in ability must be taken into account when designing products and training programs for aging adults, and we discuss new tools to support designers. The most promising emerging technologies likely lie in training cognitive abilities and augmenting or substituting for impaired abilities. We discuss reasons to expect that the lag in technology adoption between younger and older adults may lessen but will not disappear in future generations.     

Differential age effects in load-dependent memory processing

This study examined differential age effects in a young and a middle-aged sample by means of a sequential n-back task with increasing memory load. Participants processed two streams of stimuli either separately as a single task, or simultaneously as a dual task. We investigated age effects as a function of memory load in both the single and the dual-task version. In accuracy, we observed differential age effects as a function of load, which were more prominent in the dual-compared to the single-task versions. That is, middle-aged participants performed poorer than young adults in the dual-task conditions, suggesting that early age-related changes become especially apparent in conditions where task coordination and resource sharing come into play. Regarding latencies, we observed no differential age effect, which we believe is due to characteristics of the sequential n-back task.     

Chinese translation norms for 1,429 English words

We present Chinese translation norms for 1,429 English words. Chinese-English bilinguals (N = 28) were asked to provide the first Chinese translation that came to mind for 1,429 English words. The results revealed that 71 % of the English words received more than one correct translation indicating the large amount of translation ambiguity when translating from English to Chinese. The relationship between translation ambiguity and word frequency, concreteness and language proficiency was investigated. Although the significant correlations were not strong, results revealed that English word frequency was positively correlated with the number of alternative translations, whereas English word concreteness was negatively correlated with the number of translations. Importantly, regression analyses showed that the number of Chinese translations was predicted by word frequency and concreteness. Furthermore, an interaction between these predictors revealed that the number of translations was more affected by word frequency for more concrete words than for less concrete words. In addition, mixed-effects modelling showed that word frequency, concreteness and English language proficiency were all significant predictors of whether or not a dominant translation was provided. Finally, correlations between the word frequencies of English words and their Chinese dominant translations were higher for translation-unambiguous pairs than for translation-ambiguous pairs. The translation norms are made available in a database together with lexical information about the words, which will be a useful resource for researchers investigating Chinese-English bilingual language processing.     

The Use of the Racial/Cultural Identity Development Model to Understand a Vietnamese American: A Research Case Study

This article presents the sociohistorical experiences of Vietnamese Americans that contextualize the therapeutic relationship. Using a case study approach, researchers illustrate the use of the Racial/Cultural Identity Development model (D. W. Sue & D. Sue, 2003) in the analysis of an interview with a young, adult, Vietnamese immigrant. Este artículo muestra las experiencias histórico‐sociales de Americanos Vietnamitas que contextualizan la relación terapéutica. Empleando la aproximación de un estudio de caso, investigadores ilustran el uso del modelo de Desarrollo de Identidad Racial/Cultural por sus siglas en inglés, de D.W. Sue & D. Sue, 2003, en el análisis de una entrevista con un inmigrante Vietnamita adulto y joven.     

The effects of inventory on vowel perception in French and Spanish: an MEG study

Production studies have shown that speakers of languages with larger phoneme inventories expand their acoustic space relative to languages with smaller inventories [Bradlow, A. (1995). A comparative acoustic study of English and Spanish vowels. Journal of the Acoustical Society of America, 97(3), 1916-1924; Jongman, A., Fourakis, M., & Sereno, J. (1989). The acoustic vowel space of Modern Greek and German. Language Speech, 32, 221-248]. In this study, we investigated whether this acoustic expansion in production has a perceptual correlate, that is, whether the perceived distance between pairs of sounds separated by equal acoustic distances varies as a function of inventory size or organization. We used magnetoencephalography, specifically the mismatch field response (MMF), and compared two language groups, French and Spanish, whose vowel inventories differ in size and organization. Our results show that the MMF is sensitive to inventory size but not organization, suggesting that speakers of languages with larger inventories perceive the same sounds as less similar than speakers with smaller inventories.     

The Character of Yhwh and the Ethics of the Old Testament: is Imitatio Dei Appropriate?

The aim is to examine the character of the God of the Old Testament,principally in the Pentateuch, to discover whether it providesan appropriate basis for the imitatio dei that a number of writershave argued is prominent in Old Testament ethics. The articlebegins with a survey of this literature and opposing arguments.Texts then, first, that explicitly recommend the imitation ofGod are studied, then ones that imply it, mainly concerningdistributive justice. It is shown that the moral role of YHWHmay reflect one of two roles in human society, as king (of theworld) or as patron (of Israel), thus providing models for humanbeings playing such roles. A discussion of Exod. 34:5–6shows that forgiveness is for human beings as for God a rightrather than an obligation in the Old Testament. It is finallyshown that YHWH behaves in the story of the Exodus in ways which,whether justifiable (in the role of king) or not, would be inappropriatefor imitation. It is concluded that while YHWH may often beunderstood as offering a role for imitation, imitatio dei isnot the key to all Old Testament ethics.     

Listeners' cognitive and affective reactions to English speakers with standard American English and Asian Accents

Using a 2 (speaker accent: standard American, Asian) x 2 (speakers' sex: male, female) between-subjects design, the present study examined the effects of accent and sex on listeners' cognitive and affective reactions towards speakers with standard American English accents and Asian accents. 70 female and 27 male college students (M = 21.8 yr., SD = 4.7) listened to the audio recording of a monologue by one of the speakers in the early 20s who differed in accent and sex. Standard American English was operationalized as nonaccented English, typical of the western part of the USA, and Vietnamese-accented English was used as an exemplar of Asian-accented English. Results showed that relative to standard American-accented English speakers, Asian-accented English speakers were perceived as poorer communicators who were less potent, less threatening, and more concerned about others. These cognitive reactions to Asian-accented English speakers include (a) the general stereotype associated with an accent, status and solidarity, as well as (b) the stereotype unique to Asians as an ethnic group, being concerned for others and poorer communicators. Analysis also showed that speakers with an Asian accent evoked more negative affect and required more attention from listeners than did speakers with a standard American English accent. Implications of the study are discussed.     

Decomposing intuitive components in a conceptual problem solving task

Research into intuitive problem solving has shown that objective closeness of participants' hypotheses were closer to the accurate solution than their subjective ratings of closeness. After separating conceptually intuitive problem solving from the solutions of rational incremental tasks and of sudden insight tasks, we replicated this finding by using more precise measures in a conceptual problem-solving task. In a second study, we distinguished performance level, processing style, implicit knowledge and subjective feeling of closeness to the solution within the problem-solving task and examined the relationships of these different components with measures of intelligence and personality. Verbal intelligence correlated with performance level in problem solving, but not with processing style and implicit knowledge. Faith in intuition, openness to experience, and conscientiousness correlated with processing style, but not with implicit knowledge. These findings suggest that one needs to decompose processing style and intuitive components in problem solving to make predictions on effects of intelligence and personality measures.     

Multimodal Treatments for Childhood Attention-deficit/Hyperactivity Disorder: Interpreting Outcomes in the Context of Study Designs

The goal of this article was to outline issues critical to evaluating the literature on incremental benefit of multiple effective treatments used together, vs. a single effective treatment, for childhood ADHD. These issues include: (1) sequencing and dosage of treatments being combined and compared; (2) difficulty drawing valid conclusions about individual components of treatment when treatment packages are employed; (3) differing results emerging from measurement tools that purportedly measure the same domain; and (4) the resultant difficulty in reaching a summary conclusion when multiple outcome measures yielding conflicting results are used. The implications of these issues for the design and conduct of future studies are discussed, and recommendations are made for future research.
