Differences in the oscillatory EEG dynamics of reading open class (OC) and closed class (CC) words have previously been found (Bastiaansen et al., 2005) and are thought to reflect differences in lexical-semantic content between these word classes. In particu-lar, the theta-band (4-7 Hz) seems to play a prominent role in lexical-semantic retrieval. We tested whether this theta effect is robust in an older population of subjects. Additionally, we examined how the context of a word can modulate the oscillatory dynamics underly-ing retrieval for the two different classes of words. Older participants (mean age 55) read words presented in either syntactically correct sentences or in a scrambled order ("scram-bled sentence") while their EEG was recorded. We performed time-frequency analysis to examine how power varied based on the context or class of the word. We observed larger power decreases in the alpha (8-12 Hz) band between 200-700 ms for the OC compared to CC words, but this was true only for the scrambled sentence context. We did not observe differences in theta power between these conditions. Context exerted an effect on the alpha and low beta (13-18 Hz) bands between 0 and 700 ms. These results suggest that the previously observed word class effects on theta power changes in a younger participant sample do not seem to be a robust effect in this older population. Though this is an indi-rect comparison between studies, it may suggest the existence of aging effects on word retrieval dynamics for different populations. Additionally, the interaction between word class and context suggests that word retrieval mechanisms interact with sentence-level comprehension mechanisms in the alpha-band.

Students in higher professional education are prepared for high level professional practice. To be able to fulfil their future roles, their educational programs aid them in developing their professionalism. This paper presents the conceptual and empirical search for a measurement model on professionalism. Professionalism is a multifaceted construct which is at best vaguely described in previous research. It is here conceptualized through the conceptual model by Griffioen (2019) as a personal integration of professional identity, professional knowledge and professional action that transforms over time through accommodation and assimilation practices. These practices imply the development of the (future) professional. Additionally, initial findings of the development of professionalism in students during their 4 year undergraduate degree are discussed.
In this article, the outcomes of a survey aimed to investigate how aware of and how capable coaches in higher vocational Dutch education perceive themselves to assist students displaying mental health and well-being issues are presented. Additionally, the article explores coaches’ perceptions regarding the frequency, form of help offered, topics to be tackled and the preferred form in which this help should be provided. The author conducted a survey that gathered qualitative and quantitative data from coaches (N 5 82) at a Dutch University of Applied Sciences in the north of the Netherlands. A differentiation in coaches’ number of years of teaching and coaching experience was considered.
