Learning new word meanings from context: a study of eye movements

This study examined how readers establish the meaning of a new word from the sentence context during silent reading. Readers' eye movements were monitored while they read pairs of sentences containing a target word, context, and a word related to the target word. The target word varied in familiarity (high, low, or novel). The context varied in informativeness about the meaning of the target word (informative or neutral). The amount of time readers spent on the context depended on both the familiarity of the target word and the informativeness of the context. Readers spent additional time on the related word only when the context was neutral and the target was novel. These results indicate that readers were able to determine which areas of text were relevant and used the information to infer a meaning for the novel word.     

The premack principle, response deprivation, and establishing operations

This paper describes response deprivation as an establishing operation. In this context, we review the concept of establishing operation, in particular, its reinforcer-establishing and evocative effects; we place response deprivation in the literature on the reinforcing effects of behavioral activity, wherein response deprivation subsumes the Premack principle; we describe the reinforcer-altering and evocative effects of response deprivation; and we address a methodological concern about the evocative effect. In closing, we discuss some conceptual and empirical implications of the foregoing analyses.     

A sublexical locus for repetition blindness: evidence from illusory words.

Six experiments used an illusory words paradigm to demonstrate that repetition blindness (RB) in orthographically similar words affects only the words' shared letters. Rapid serial visual presentation streams of words and word fragments allowed the unique letters of the 2nd critical word to combine with a subsequent fragment to create a word, as in rock shock ell. The illusory word shell was reported 2-3 times as frequently in RB conditions as in control conditions. Further experiments ruled out letter migration, contour summation, and differences in processing load as explanations for the results. These findings are inconsistent with current proposals that orthographic RB represents similarity inhibition or lexical competition or that it reflects problems with word-level token individuation.     

An Analysis on the Research Ethics Cases Managed by the Committee on Publication Ethics (COPE) Between 1997 and 2010

The growing emphasis on the importance of publishing scientific findings in the academic world has led to increasing prevalence of potentially significant publications in which scientific and ethical rigour may be questioned. This has not only hindered research progress, but also eroded public trust in all scientific advances. In view of the increasing concern and the complexity of research misconduct, the Committee on Publication Ethics (COPE) was established in 1997 to manage cases with ethical implications. In order to review the outcomes of cases investigated by COPE, a total of 408 cases that had been managed by COPE were successfully extracted and analysed with respect to 7 distinct criteria. The results obtained indicate that the number of ethical implications per case has not changed significantly (p?>?0.01) since the year COPE was instigated. Interestingly, the number of ethical cases, and to some extent, research misconduct, is not diminishing. Therefore, journal editors and publishers need to work closely together with COPE to inculcate adoption of appropriate research ethics and values in younger researchers while discouraging others from lowering standards. It is hoped that with a more concerted effort from the academic community and better public awareness, there will be fewer incidences of ethically and scientifically challenged publications. The ultimate aim being to enhance the quality of published works with concomittant public trust in the results.     

“Practical Divine Influence”: Socioeconomic Status and Belief in the Prosperity Gospel

The “prosperity gospel” is an understudied feature of the religious landscape of the United States. Little is known about the social patterning of prosperity gospel beliefs. We focus on two core dimensions of socioeconomic status (SES)—education and income—as potential influences. Our analyses of data from the Pew Forum on Religion & Public Life's 2006 Survey of Pentecostals produce three findings. First, education and income have negative and mostly independent associations with prosperity gospel beliefs. Second, SES‐based patterns remain after accounting for other attributes of the religious role. Third, while most education‐based differences are contingent upon the attributes of the religious role, these contingencies are not replicated for income‐based differences. These observations reinforce the long‐standing claim that SES plays a pivotal—and complex—role in the social patterning of religious beliefs.     

Cross-national differences in older adult loneliness

Loneliness concerns the subjective evaluation that the number of relationships is smaller than the individual considers desirable or that the intimacy that the individual wishes for has not been realized. The aim of this study was to assess variations in levels of late-life loneliness and its determinants across Europe. Data came from the SHARE surveys, Wave 2 (Borsch-Supan et al., 2008), encompassing adults aged 50 years and over in Austria, Belgium, the Czech Republic, Denmark, France, Germany, Greece, Ireland, Italy, the Netherlands, Poland, Spain, Sweden, and Switzerland (N = 12,248). Loneliness was measured by a single item derived from the CES-D (depression) scale. Using logistic models, the present authors tested several types of explanations for country differences: differences in demographic characteristics, wealth and health, and social networks. Older adults in the southern and central European countries were generally lonelier than their peers in the northern and western European countries. In the southern and central European countries, loneliness was largely attributable to not being married, economic deprivation, and poor health. Frequent contacts with parents and adult children, social participation, and providing support to family members were important in preventing and alleviating loneliness in almost all countries. To combat loneliness among older adults, the findings suggest both (a) generic approaches aimed at improving social embeddedness and (b) country-tailored approaches aimed at improving health and wealth.
