Homophonic context effects when naming Japanese kanji: evidence for processing costs?

The current study investigated the effects of phonologically related context pictures on the naming latencies of target words in Japanese and Chinese. Reading bare words in alphabetic languages has been shown to be rather immune to effects of context stimuli, even when these stimuli are presented in advance of the target word (e.g., Glaser & Düngelhoff, 1984 ; Roelofs, 2003 ). However, recently, semantic context effects of distractor pictures on the naming latencies of Japanese kanji (but not Chinese hànzì) words have been observed (Verdonschot, La Heij, & Schiller, 2010 ). In the present study, we further investigated this issue using phonologically related (i.e., homophonic) context pictures when naming target words in either Chinese or Japanese. We found that pronouncing bare nouns in Japanese is sensitive to phonologically related context pictures, whereas this is not the case in Chinese. The difference between these two languages is attributed to processing costs caused by multiple pronunciations for Japanese kanji.     

Nanotechnologies and Novel Foods in European Law

Food is a big business in the EU and nanofood products are beginning to be placed on the market. It is still unclear whether the absence of minimum regulation at a global level promotes or prevents the growth of a market in nanofood. However, the development of an adequate risk management policy in relation to food safety is a key concern for consumers. Importantly, the European Parliament in its 2009 Resolution on “Legal aspects on nanomaterials” called for more in-depth scientific research on the toxicity of compounds in nanomaterials, and for the adoption of an EU definition of nanomaterials for regulatory purposes. Unfortunately, in 2011, nanotechnology led to inconclusive debates in the context of the revision of Novel Food Regulation. General Food Law applies to nanofood in terms of safety requirements, and specific rules also apply to food contact materials containing nanoparticles as well as to to additives, vitamins and minerals. The EU legislator also introduced mandatory labelling in respect of products derived from nanotechnologies. The legal framework is evolving according to the so-called “incremental approach”, a governance model that creates the risk of fragmentation. But the main problem is the inconsistent definition of the terms “nanotechnology” and “nanomaterials” when looking at the enforcement of regulations and the provision of a wide range of specific tools for different nanofoods: for example the use of positive lists of authorised substances applying only to food contact materials, additives and supplements. This contribution aims to review the regulations in force in respect to nanofood and novel foods and to highlight the problems that are still unresolved.     

Do humans and nonhuman animals share the grouping principles of the iambic–trochaic law?

The iambic–trochaic law describes humans’ tendency to form trochaic groups over sequences varying in pitch or intensity (i.e., the loudest or highest sounds mark group beginnings), and iambic groups over sequences varying in duration (i.e., the longest sounds mark group endings). The extent to which these perceptual biases are shared by humans and nonhuman animals is yet unclear. In Experiment 1, we trained rats to discriminate pitch-alternating sequences of tones from sequences randomly varying in pitch. In Experiment 2, rats were trained to discriminate duration-alternating sequences of tones from sequences randomly varying in duration. We found that nonhuman animals group sequences based on pitch variations as trochees, but they do not group sequences varying in duration as iambs. Importantly, humans grouped the same stimuli following the principles of the iambic–trochaic law (Exp. 3). These results suggest the early emergence of the trochaic rhythmic grouping bias based on pitch, possibly relying on perceptual abilities shared by humans and other mammals, whereas the iambic rhythmic grouping bias based on duration might depend on language experience.     

Opinion‐based group membership as a predictor of commitment to political action

Research on group identification has shown it to be a surprisingly weak predictor of intentions to take large‐scale social action. The weak links may exist because researchers have not always examined identification with the type of group that is most relevant for predicting action. Our focus in two studies (one in Romania and one in Australia, both Ns = 101) was on opinion‐based groups (i.e. groups formed around shared opinions). We found that social identification with opinion‐based groups was an excellent predictor of political behavioural intentions, particularly when items measuring identity certainty were included. The results provide clear evidence of the role of social identity constructs for predicting commitment to social action and complement analyses of politicised collective identity and crowd behaviour.

Quality of Life (QoL) in a Brazilian Sample of Older Adults: The Role of Sociodemographic Variables and Depression Symptoms

The aim of the present study was to identify relevant variables associated with Quality of Life (QoL) in older adults. Older adults, up to 60 years old, were interviewed. Subjects were recruited through convenience sampling. 339 paticipants, who were stratified by gender, age, and subjective perception of health and illness, answered questions on sociodemographic issues, QoL (WHOQOL-100) and depressive symptomathology (Beck Depression Inventory—BDI). The multiple linear regression analysis showed associations of overall perception of QoL with depression levels, subjective perception of health status and gender. The individual analysis of each domain concluded that depression levels are correlated to all QoL domains, while health status was associated with physical, psychological, independence level and social relationship domains. Other variables were also assessed. The assessment of older adults concerning their QoL perceptions is associated with gender, age, marital status, social class, literacy rate, perception of health, and more substantially associated with depressive symptoms levels. Nevertheless, some limitations of this study and further ones are suggested.     

British English norms for the spontaneous completion of three-letter word stems

Word stem completion tasks involve showing participants a number of words and then later asking them to complete word stems to make a full word. If the stem is completed with one of the studied words, it indicates memory. It is a test widely used to assess both implicit and explicit forms of memory. An important aspect of stimulus selection is that target words should not frequently be generated spontaneously from the word stem, to ensure that production of the word really represents memory. In this article, we present a database of spontaneous stem completion rates for 395 stems from a group of 80 British undergraduate psychology students. It includes information on other characteristics of the words (word frequency, concreteness, imageability, age of acquisition, common part of speech, and number of letters) and, as such, can be used to select suitable words to include in a stem completion task.
