How native-like is non-native language processing?

Following several decades of research on native language (L1) processing, psycholinguists have more recently begun to investigate how non-native language (L2) speakers comprehend and process language in real time. Regarding the traditional assumption that L2 learners have 'difficulty with grammar', this new research has revealed some unexpected similarities and differences between L1 and L2 processing. Specifically, it appears that L2 processing can become native-like in some linguistic subdomains (including certain aspects of grammar) but that L1 and L2 processing differences persist in the domain of complex syntax, even in highly proficient L2 speakers. Thus, more subtle linguistic distinctions seem to be required to understand the nature of non-native language processing.     

I haven't thought about this for years! Dating recent recalls of vivid memories

In three studies, we examined memories for previous recall. In Studies 1 and 2, undergraduates were asked whether they had vivid memories about various childhood events. After a one‐hour (Study 1) or 2‐week (Study 2) interval, they completed a second questionnaire containing new, but also previously presented childhood items. Participants estimated how recently they had thought about old and new items. A non‐trivial proportion of recent recalls of vivid childhood memories was dated incorrectly. In Study 3, women with recovered and continuous memories of childhood sexual abuse (CSA) completed the childhood events questionnaires used in studies 1 and 2. After a one‐hour interval, they indicated how recently they had thought about new, but also previously presented childhood items. Compared to women with continuous CSA memories, women with recovered memories underestimated their prior remembering. Copyright © 2005 John Wiley & Sons, Ltd.     

Antecedent Priming at Trace Positions in Children’s Sentence Processing

The present study examines whether children reactivate a moved constituent at its gap position and how children’s more limited working memory span affects the way they process filler-gap dependencies. 46 5–7 year-old children and 54 adult controls participated in a cross-modal picture priming experiment and underwent a standardized working memory test. The results revealed a statistically significant interaction between the participants’ working memory span and antecedent reactivation: High-span children (n = 19) and high-span adults (n = 22) showed evidence of antecedent priming at the gap site, while for low-span children and adults, there was no such effect. The antecedent priming effect in the high-span participants indicates that in both children and adults, dislocated arguments access their antecedents at gap positions. The absence of an antecedent reactivation effect in the low-span participants could mean that these participants required more time to integrate the dislocated constituent and reactivated the filler later during the sentence.     

A pilot study of urinary peptides as biomarkers for intelligence in old age

Intelligence is an important indicator of physical, mental and social well-being. In old age, intelligence is also associated with a higher quality of life and better health. Heritability studies have shown that there are strong genetic influences, yet unknown, on intelligence, including in old age. Other approaches may be useful to investigate the biological foundations of intelligence differences. Proteomics is a proven technique in revealing biomarkers for certain illnesses. In this pilot study, forty individuals were selected as the cognitive extremes from over 750 people in the Lothian Birth Cohort 1936 (age ~ 72 years) based on their high and low intelligence scores, as measured by a general cognitive ability factor. Urine samples were used as a stable, reliable and abundant source of proteins. Using capillary electrophoresis coupled to mass spectrometry (CE-MS) technology, the proteome of the high and low intelligence groups was determined. Data were calibrated and matched against the human urinary database, to enable comparative assessment. At a nominal significance level (P < 0.05), there were several candidate proteins for association with intelligence, including a zinc finger protein (ZNF653) that has been associated with cognitive deficits, and complement C3 and collagen fragments that have been associated with Alzheimer's disease. Results are preliminary, do not survive multiple testing correction, and require validation. This pilot study shows the potential of this novel proteomics approach, and its applicability to understanding the biological foundations of intelligence differences.     

Typical performance measures of emotion regulation and emotion perception and frontal EEG asymmetry in an emotional contagion paradigm

In order to replicate and extend previous observations of validity of the self-reported habitual regulation of one’s affect and the perception of other people’s emotions, prefrontal electroencephalographic (EEG) asymmetry was recorded during and after social-emotional stimulation. After stimulation with other people’s vocal expression of anxiety, individuals with lower scores on emotion regulation did not show recovery of asymmetry changes but even increased changes in the direction that had been adopted during the stimulation. Whether this was to the right or to the left depended on their scores on emotion perception. Participants high on perception showed the expected changes to the right during the anxiety stimulation (indicating increased withdrawal motivation) and to the left during the cheerfulness stimulation (indicating increased approach motivation), whereas individuals low on perception showed the opposite pattern. During the anxiety stimulation, participants low on perception only showed the unexpected change to the left if they were also low on regulation. Individual differences in regulation did not play a role when participants were confronted with other people’s laughter. The findings demonstrate the validity of the self-report measures by using EEG measures, and moreover support the usefulness of differentiated and process-oriented approaches in the field of trait emotional intelligence.     

The staff observation aggression scale–revised (SOAS‐R)

Proper assessment of aggressive behavior is essential for an understanding of its causes. In 1987, Palmstierna and Wistedt [Acta Psychiatr Scand 76:657‐663] introduced the Staff Observation Aggression Scale (SOAS), an instrument for monitoring the frequency, nature, and severity of aggressive incidents. In the present study, the validity of the SOAS severity scoring system was examined, and the severity scores were refined. The SOAS was used to record aggression on six closed wards of three psychiatric hospitals. The SOAS severity scores of 556 aggressive incidents were compared with severity estimates given on Visual Analogue Scales (VASs) by staff members. The original SOAS scores were found to be moderately correlated with the estimates of severity given by staff on the VAS. The SOAS severity scoring system was refined on the basis of the staff severity estimates. The revised scoring method and other refinements in the contents of the instrument led to the construction of the SOAS‐R. The SOAS‐R seems to be a promising tool for monitoring a wide range of (self‐) destructive acts on psychiatric wards. Aggr. Behav. 25:197–209, 1999. © 1999 Wiley‐Liss, Inc.     

Personal values and political activism: A cross‐national study

Using data from 28 countries in four continents, the present research addresses the question of how basic values may account for political activism. Study (N = 35,116) analyses data from representative samples in 20 countries that responded to the 21‐item version of the Portrait Values Questionnaire (PVQ‐21) in the European Social Survey. Study (N = 7,773) analyses data from adult samples in six of the same countries (Finland, Germany, Greece, Israel, Poland, and United Kingdom) and eight other countries (Australia, Brazil, Chile, Italy, Slovakia, Turkey, Ukraine, and United States) that completed the full 40‐item PVQ. Across both studies, political activism relates positively to self‐transcendence and openness to change values, especially to universalism and autonomy of thought, a subtype of self‐direction. Political activism relates negatively to conservation values, especially to conformity and personal security. National differences in the strength of the associations between individual values and political activism are linked to level of democratization.     

The recognition of reduced word forms

This article addresses the recognition of reduced word forms, which are frequent in casual speech. We describe two experiments on Dutch showing that listeners only recognize highly reduced forms well when these forms are presented in their full context and that the probability that a listener recognizes a word form in limited context is strongly correlated with the degree of reduction of the form. Moreover, we show that the effect of degree of reduction can only partly be interpreted as the effect of the intelligibility of the acoustic signal, which is negatively correlated with degree of reduction. We discuss the consequences of our findings for models of spoken word recognition and especially for the role that storage plays in these models.
