Givenness, complexity, and the Danish dative alternation

In this study, we investigated the interaction between givenness and complexity on the choice of syntactic structure, via two experiments using speeded acceptability judgments. Experiment 1 showed that for the Danish dative alternation, given–new orders are only easier to process for double-object or NP constructions, whereas PP constructions are unaffected. This replicates previous findings for the English dative alternation. Experiment 2 revealed that when a long NP precedes a short NP—a suboptimal complexity relation—the effect of givenness is neutralized, whereas givenness remains influential when the complexity relation between the NPs in the sentence is optimal. This is consistent with the view that in online parsing, the actual syntactic structure-building process is primary, whereas any higher-order computations such as discourse linking are secondary. The relative complexity of the NPs in the double-object construction directly affects the structure-building process, whereas the decoding of the discourse structure is a later and less crucial phenomenon, resulting in neutralization of the givenness effect in cases in which the complexity relation is suboptimal.     

Evidence for Implicit Learning in Syntactic Comprehension

This study provides evidence for implicit learning in syntactic comprehension. By reanalyzing data from a syntactic priming experiment (Thothathiri & Snedeker, 2008), we find that the error signal associated with a syntactic prime influences comprehenders' subsequent syntactic expectations. This follows directly from error‐based implicit learning accounts of syntactic priming, but it is unexpected under accounts that consider syntactic priming a consequence of temporary increases in base‐level activation. More generally, the results raise questions about the principles underlying the maintenance of implicit statistical knowledge relevant to language processing, and about possible functional motivations for syntactic priming.     

Visual image retention does not contribute to modulation of event-related potentials by mental rotation

Rotation of a visual image in mind is associated with a slow posterior negative deflection of the event-related potential (ERP), termed rotation-related negativity (RRN). Retention of a visual image in short-term memory is also associated with a slow posterior negative ERP, termed negative slow wave (NSW). We tested whether short-term memory retention, indexed by the NSW, contributes to the RRN. ERPs were recorded in the same subjects in two tasks, a mental rotation task, eliciting the RRN, and a visual short-term memory task, eliciting the NSW. Over both right and left parietal scalp, no association was found between the NSW and the RRN amplitudes. Furthermore, adjusting for the effect of the NSW had no influence on a significant association between the RRN amplitude and response time, an index of mental rotation performance. Our data indicate that the RRN reflects manipulation of a visual image but not its retention in short-term memory.     

Does habit strength moderate the intention–behaviour relationship in the Theory of Planned Behaviour? The case of fruit consumption

The present study examined if habit strength moderated the influence of intention on fruit consumption in a Dutch adult sample (N?=?521, 46.3% males, mean age?=?34.50, SD?=?10.87), using the theoretical relations of the Theory of Planned Behaviour (TPB). TPB variables and habit strength were assessed at baseline. Fruit consumption was assessed with a validated questionnaire five weeks later. Three groups were created: low habit strength (n?=?180), medium habit strength (n?=?185) and high habit strength (n?=?156). Confirmatory factor analyses and multi-group path analyses were performed using AMOS 4.0. A good fit was obtained for the overall measurement model and the structural models. Multi-group path analyses showed that intention was a significant predictor of fruit consumption in the low habit (β?=?0.36, p?<?0.001) and medium habit group (β?=?0.30, p?<?0.001), but a non-significant predictor in the high habit group (β?=?0.05, p?=?0.596). Implications for information-based and motivation-based interventions are discussed.     

Adolescents’ movement towards cessation of smoking: Role and relative value of the processes of change and nicotine dependence

The present study addresses the applicability of the Transtheoretical Model's processes of change in explaining adolescents’ readiness to quit smoking. Furthermore, the association between nicotine dependence and readiness to quit was assessed both directly, as well as indirectly through the processes of change. A cross-sectional survey was conducted, identifying 1547 weekly smokers aged 14–18 years. Structural equation modelling showed that the processes of change were only marginally associated with readiness to quit. Adding nicotine dependence to the model showed a direct association between nicotine dependence and readiness to quit. Only one process of change, self-liberation (i.e. choice/commitment to change and belief in the ability to change), was found to mediate this association. Nicotine dependence appeared to be highly important in adolescents’ readiness to quit.     

Predictors of willingness to register as an organ donor among dutch adolescents

Abstract

In order to identify relevant determinants of organ donor registration among Dutch adolescents, a school-based cross-sectional survey was conducted among 145 high school students. Fifty-one percent of respondents indicated they were willing to register as organ donors and 80% reported a positive general attitude towards registration. Various misconceptions about the registration and donation procedure were identified. On average only moderate knowledge levels related to organ donation were found. In order of strongest association, negative outcome expectancies, past behaviour and experience, positive outcome expectancies, and social outcome expectancies proved to be significant predictors of willingness to register as organ donors. Self-efficacy was indirectly associated with willingness via outcome expectancies. Knowledge about organ donation was not significantly associated with willingness. The results suggest that in order to persuade adolescents to register as organ donors, refutational messages will have to be developed to counterargue the prevailing negative outcome expectancies related to organ donation and registration as an organ donor.     

What Harmony Could and Could Not Be

The notion of harmony has played a pivotal role in a number of debates in the philosophy of logic. Yet there is little agreement as to how the requirement of harmony should be spelled out in detail or even what purpose it is to serve. Most, if not all, conceptions of harmony can already be found in Michael Dummett's seminal discussion of the matter in The Logical Basis of Metaphysics. Hence, if we wish to gain a better understanding of the notion of harmony, we do well to start here. Unfortunately, however, Dummett's discussion is not always easy to follow. The following is an attempt to disentangle the main strands of Dummett's treatment of harmony. The different variants of harmony as well as their interrelations are clarified and their individual shortcomings qua interpretations of harmony are demonstrated. Though no attempt is made to give a detailed alternative account of harmony here, it is hoped that our discussion will lay the ground for an adequate rigorous treatment of this central notion.     

Infants' Developing Sensitivity to Object Function: Attention to Features and Feature Correlations

In this research we examine the relation between executive function (EF) and false-belief (FB) understanding in young children. Specifically, we proposed that performance on tasks combining 2 executive demands: (a) working memory and (b) inhibitory control would be most predictive of performance on FB tasks. Forty-eight children between the ages of 3 and 5 years were given a battery of EF and FB measures. As predicted we found that performance on executive tasks that combined demands for memory and inhibitory control were highly predictive of performance on FB tasks. To further test the relation of EF and FB understanding we also introduced an experimental manipulation designed to reduce the working memory demands of FB tasks. This manipulation did not significantly improve performance. The results from this study provide support for the relation between EF and FB understanding, although the exact nature of the relation requires further clarification.     

Substitutes for leadership in anaesthesia teams and their impact on leadership effectiveness

In this study we aim to increase our understanding of leadership in anaesthesia teams by investigating the relationship between substitutes for leadership, leadership behaviour, and team performance in situations with varying levels of routine and standardization. The present study relied on video recordings of 12 anaesthesia teams in a simulated setting with the occurrence of a nonroutine event. Clinical team performance was measured by the speed of adequate team reaction to this event. The leadership behaviours observed were coded either as content oriented (e.g., information transmission) or structuring (e.g., assigning tasks). Results showed that leadership behaviour changed depending upon the level of routine of a situation, the degree of standardization, and, to some extent, on the experience of team members. Leadership tends to be positively related to team performance during nonroutine and low standardized situations but negatively related to team performance in routine and highly standardized situations. Furthermore, leadership is only slightly related to team member experience. This study improves our understanding of influences of substitutes for leadership on successful leadership behaviour in anaesthesia teams. The findings also lead to suggestions for both further research and the enhancement of team leadership in critical care.     

A Group of Sexually Abused Adolescents' Perceptions of their Future Life-Roles: An Exploratory Study

Sexual abuse of adolescents can have detrimental effects on their perceptions of their different future life-roles. We investigated such perceptions of students with a history of sexual abuse (n=163) as well as typically developing others (n=237). Participants completed the Life-role Inventory of the then called Human Sciences Research Council (Langley, 1990). Between-group comparisons were carried out. Adolescents with a history of sexual abuse reported negative perceptions of themselves fulfilling some of their roles in the future, being committed to these roles and attaching value to them, compared to typically developing others.
