School Achievement of Immigrant Children: The Decreasing Influence of Ethnic Concentration

There is an ongoing debate in many countries about the assumed negative influence of ethnically concentrated schools on pupils’ cognitive development. This paper addresses the influence of concentrations of ethnic minority children in schools on the school achievement of their pupils. The analysis covers the period 1988–2004 and is based on a very large (60,000 pupils in each edition) longitudinal survey of the school achievement of primary school pupils, which was held every 2 years in the Netherlands. It reveals that the educational achievements of pupils from ethnic minority groups are improving, more so in arithmetic than in language. The paper examines whether ethnically concentrated schools make up the gap. We find that ethnically concentrated schools appear to become more and more adept at dealing with the educational disadvantage of ethnic minority children: they are making greater progress in educational achievement than schools with few ethnic minority children. Over the 15-year period studied, ethnically concentrated schools have removed around half the language disadvantage compared to ‘white’ schools, and as much as even three-quarters of the gap in arithmetic.     

Effect of interaction type on the characteristics of pet-directed speech in female dog owners

Recent studies focusing on the interspecific communicative interactions between humans and dogs show that owners use a special speech register when addressing their dog. This register, called pet-directed speech (PDS), has prosodic and syntactic features similar to that of infant-directed speech (IDS). While IDS prosody is known to vary according to the context of the communication with babies, we still know little about the way owners adjust acoustic and verbal PDS features according to the type of interaction with their dog. The aim of the study was therefore to explore whether the characteristics of women’s speech depend on the nature of interaction with their dog. We recorded 34 adult women interacting with their dog in four conditions: before a brief separation, after reuniting, during play and while giving commands. Our results show that before separation women used a low pitch, few modulations, high intensity variations and very few affective sentences. In contrast, the reunion interactions were characterized by a very high pitch, few imperatives and a high frequency of affectionate nicknames. During play, women used mainly questions and attention-getting devices. Finally when commanding, women mainly used imperatives as well as attention-getting devices. Thus, like mothers using IDS, female owners adapt the verbal as well as the non-verbal characteristics of their PDS to the nature of the interaction with their dog, suggesting that the intended function of these vocal utterances remains to provide dogs with information about their intentions and emotions.     

Parental Empowerment: Construct Validity and Reliability of a Dutch Empowerment Questionnaire (EMPO)

In this study, the construct validity and reliability of the Empowerment questionnaire (EMPO) that was developed in Dutch youth care was examined. The 12-item EMPO focuses on measuring parental empowerment in raising their children. The three components of psychological empowerment (intrapersonal, interactional, and behavioral) form the rationale for the EMPO. Non-clinical (n?=?673) and clinical (n?=?1,212) data were used. Construct validity was tested by the factorial structure, measurement invariance, correlations with other instruments (PSQ-S and SDQ), and empowerment differences between the two groups. Reliability was determined by testing the internal consistency and test-retest reliability. The results show that the factorial validity of the EMPO was sufficient to good, the EMPO was measurement invariant for various subgroups, and the EMPO scales were negatively correlated with parenting stress (PSQ-S) and child behavioral problems scales (SDQ). Furthermore, the clinical group was less empowered, and the correlation between parental empowerment and child behavioral problems was stronger in this group. In addition, both groups of parents had relatively high scores on the interactional component. In the clinical group, however, parental scores on the interactional component were less correlated with scores on the intrapersonal and behavioral components. Finally, reliability analyses showed a largely sufficient to good internal consistency and test-retest reliability. The EMPO seems to be an instrument with sufficient to good construct validity and reliability. Further research is recommended regarding the underlying assumptions, other aspects of validity, representativeness, and the way it should be used as a tool by professionals for supporting parental empowerment.     

Timing a week later: The role of long-term memory in temporal preparation

Temporal preparation has been investigated extensively by manipulating the foreperiod, the interval between a warning stimulus and target stimulus requiring a speeded response. Although such research has revealed many effects of both the duration and distribution of foreperiods on reaction times, the underlying cognitive mechanism is still largely unknown. Here, we test a recent proposal that temporal preparation is driven by the retrieval of memory traces of past experiences from long-term memory rather than by knowledge about upcoming events. Two groups of participants received different foreperiod distributions in an acquisition phase, which was followed a week later by a transfer phase, in which both groups received the same distribution of foreperiods. We found that the effects of the different foreperiod distributions presented in the acquisition phase were still apparent a week later during the transfer phase, as the reaction time patterns of both groups reflected the old distributions. This occurred even though both groups were provided with full information about the change in the distribution of foreperiods at the start of the transfer phase. These findings provide compelling evidence that long-term memory plays an important role in temporal preparation.     

Arthur’s advice: comparing Arthur Schopenhauer’s advice on happiness with contemporary research

The German philosopher Arthur Schopenhauer (1788–1860) is well known for his pessimism. He did not believe in real happiness. In his view, the best a person can achieve is to reduce misery. At the end of his career, he wrote a book on how to live the most bearable life. This is a practical guide based on his personal experiences and illustrated by quotations from other thinkers subscribing to his views. In this paper, we summarize his recommendations and compare these with conditions for happiness as observed in present day empirical research. Little of the advice appears to fit current research on conditions for happiness. Following Schopenhauer’s advice would probably make us unhappier, even if we had the same neurotic personality.
