Cognitive correlates of depressive symptoms in 11-year-old children

Self-reports of depressive symptoms were obtained for 792 11-year-old New Zealand children using a structured interview. The aim of the present study was to test the hypothesis that depressive symptomatology in children is associated with impairment on cognitive tasks. The results did not support this hypothesis. Depression was unrelated to performance on various subscales of the WISCR, whereas self-reported inattention was associated with poor performance. Depressive symptoms, however, were significantly related to lower self-esteem and a poorer self-perception of scholastic ability.The Dunedin Multidisciplinary Health and Development Research Unit is supported by the Medical Research Council of New Zealand and the Departments of Education and Health, and involves several departments of the University of Otago. Much of the data are gathered by voluntary workers from the Dunedin community. The authors are indebted to the many people whose contributions make this ongoing study possible.     

Speech act conditions as tools for reconstructing argumentative discourse

According to the pragma-dialectical approach to argumentation, for analysing argumentative discourse, a normative reconstruction is required which encompasses four kinds of transformations. It is explained in this paper how speech act conditions can play a part in carrying out such a reconstruction. It is argued that integrating Searlean insights concerning speech acts with Gricean insights concerning conversational maxims can provide us with the necessary tools. For this, the standard theory of speech acts has to be amended in several respects and the conversational maxims have to be translated into speech act conditions. Making use of the rules for communication thus arrived at, and starting from the distribution of speech acts in a critical discussion as specified in the pragma-dialectical model, it is then demonstrated how indirect speech acts are to be transformed when reconstructing argumentative discourse.     

Doors for memory: A searchable database

The study of human long-term memory has for over 50 years been dominated by research on words. This is partly due to lack of suitable nonverbal materials. Experience in developing a clinical test suggested that door scenes can provide an ecologically relevant and sensitive alternative to the faces and geometrical figures traditionally used to study visual memory. In pursuing this line of research, we have accumulated over 2000 door scenes providing a database that is categorized on a range of variables including building type, colour, age, condition, glazing, and a range of other physical characteristics. We describe an illustrative study of recognition memory for 100 doors tested by yes/no, two-alternative, or four-alternative forced-choice paradigms. These stimuli, together with the full categorized database, are available through a dedicated website. We suggest that door scenes provide an ecologically relevant and participant-friendly source of material for studying the comparatively neglected field of visual long-term memory.     

Modulation of auditory spatial attention by visual emotional cues: differential effects of attentional engagement and disengagement for pleasant and unpleasant cues

Previous research has demonstrated that threatening, compared to neutral pictures, can bias attention towards non-emotional auditory targets. Here we investigated which subcomponents of attention contributed to the influence of emotional visual stimuli on auditory spatial attention. Participants indicated the location of an auditory target, after brief (250 ms) presentation of a spatially non-predictive peripheral visual cue. Responses to targets were faster at the location of the preceding visual cue, compared to at the opposite location (cue validity effect). The cue validity effect was larger for targets following pleasant and unpleasant cues compared to neutral cues, for right-sided targets. For unpleasant cues, the crossmodal cue validity effect was driven by delayed attentional disengagement, and for pleasant cues, it was driven by enhanced engagement. We conclude that both pleasant and unpleasant visual cues influence the distribution of attention across modalities and that the associated attentional mechanisms depend on the valence of the visual cue.     

An Examination of the Relationships Between Personality,Attitudes, and Cognitions Relevant to Alcohol-Impaired Driving Tendencies1

Previous research has explored the domain of legal and educational prevention in regard to the phenomena of accidents and injuries caused by drinking and driving. Most investigations of psychological factors attempt to distinguish characteristics of drunk drivers relative to the general driving population or controls matched on driving risk variables. In contrast, the present research concentrated on the examination of the process by which empirically derived personality and general attitudinal constructs operate within a cognitive framework to influence the decision to drive. Four conceptual models were proposed that suggested the presence of direct, indirect, and moderated effects of personality and general attitudinal constructs on cognitions relevant to drunk-driving tendencies. Support was observed for a model suggesting the presence of indirect, direct, and moderating effects for the general attitudinal construct driving aggression, and support for an indirect effects model for the personality variable emotional control. The implications of these findings are discussed in the context of utilizing personality and general attitudinal constructs to improve short term cognitive-based interventions.     

ArtWare: Macintosh multimedia software for aesthetics research

This paper describes ArtWare, a HyperCard stack for the Apple Macintosh that allows researchers to configure and run simple experiments in visual aesthetics. ArtWare allows researchers to (1) choose paintings or other works of art from commercially available laser discs to use as stimuli, (2) create and edit sets of semantic differential response scales, and (3) create an experiment stack that randomizes the presentation of stimuli and scales as well as collects data from subjects. In addition, the paper discusses revisions planned for the current software to broaden its utility to areas beyond visual aesthetics.     

Deconfessionalisation in the Netherlands, 1964–1992

Using data from 1098 national Dutch surveys, this paper explores trends in the influence of religious denomination on votes for confessional political parties in the Netherlands from 1964 to 1992. The broad question is whether confessional voting has declined over this 29‐year period; the narrow issue is whether the declines vary with religious denomination and time. Logit analysis of the overall effect allows a downward trend in the influence of denomination. The most spectacular decays occurred in the 1960s and 1970s, among Catholics and Rereformed Protestants. Many of the shifts slowed down appreciably in the late 1970s and subsequently abated in the mid‐1980s. Possible explanations for these findings are discussed.     

Integrating the ethical and social context of computing into the computer science curriculum

This paper describes the major components of ImpactCS, a program to develop strategies and curriculum materials for integrating social and ethical considerations into the computer science curriculum. It presents, in particular, the content recommendations of a subcommittee of ImpactCS; and it illustrates the interdisciplinary nature of the field, drawing upon concepts from computer science, sociology, philosophy, psychology, history and economics.     

Agoraphobia and the hyperventilation syndrome

One of the causes of agoraphobic complaints is the fear of having an attack of physical complaints in public places. The Hyperventilation Syndrome (HVS) with its diverse symptoms seems to fit well in this model. Hyperventilation symptoms are threatening, because for most subjects they occur unexpectedly and without a clear reason. An investigation was made into how often the HVS and the agoraphobic syndrome appeared together and into the causal relationship between both syndromes. About 60% of the agoraphobic patients suffered from hyperventilation complaints and about 60% of the HVS patients were agoraphobic. Most patients mentioned the fear of having an attack as an important reason for their agoraphobic complaints, and this applied especially in the case of the HVS.     

The Psychometric Properties of an Internet-Administered Version of the Depression Anxiety and Stress Scales (DASS) in a Sample of Dutch Adults

Psychometric work on the widely used Depression Anxiety and Stress Scales (DASS) has mostly used classical psychometrics and ignored common internet-administered versions. Therefore, the present study used not only classical, but also modern psychometrics based on item response theory (IRT) to evaluate an internet-administered version of the DASS (Dutch translation). Internet-administered DASS data were collected as part of a large internet-based study in the Dutch adult population (n = 7972). Initially, external correlates (i.e. demographics other measures) and some classical psychometrics (internal consistency, convergent/divergent validity) of the DASS scales were evaluated. Next, IRT was used to investigate the scales’ dimensionality, discrimination and item-functioning. Finally, the DASS depression scale was further investigated by linking it to the more clinically-oriented Quick Inventory of Depressive Symptomatology (QIDS) using item response theory (IRT). Initial classical psychometric analyses supported the scales’ internal consistency (alpha = 0.94–0.98) and convergent/divergent validity. IRT analyses showed that each of the DASS scales was only suitable to measure variations in a very narrow and rather mild severity range. Linking the DASS depression scale with the QIDS also showed that the DASS depression scale discriminated best in the mild-moderate severity range, but not at higher severity levels that were covered by the QIDS. In conclusion, the scales of the internet-administered DASS show good internal consistency and validity. However, users should be aware that the scales discriminate best at mild-moderate severity ranges in the general population.
