Oral health and dental well‐being: testing a self‐determination theory model

This study tested a self‐determination theory (SDT) process model of oral health and subjective dental well‐being. The results showed that: (1) patients' perceptions of autonomy‐supportive dental professionals were significantly positively predictive of patients' psychological needs satisfaction in treatment; (2) needs satisfaction was significantly related to perceived dental competence (positive), autonomous motivation (positive), and controlled motivation (negative) for dental care; (3) perceived competence was significantly positively, and controlled motivation was significantly negatively associated with self‐rated oral health and oral‐health‐related quality of life; (4) autonomous motivation for dental treatment was significantly positively associated with valuing continued dental treatment; and (5) the three oral‐health‐related variables were all significantly positively linked to subjective dental well‐being. A structural equation model supported the SDT process model.     

Profile of cognitive deficits and associations with depressive symptoms and intelligence in chronic early‐onset schizophrenia patients

Cognitive deficits in several domains have been demonstrated in early‐onset schizophrenia patients but their profile and relation to depressive symptoms and intelligence need further characterization. The purpose was to characterize the profile of cognitive deficits in chronic, early‐onset schizophrenia patients, assess the potential associations with depressive symptom severity, and examine whether cognitive deficits within several domains reflect intelligence impairments. This study compared attention, visual‐construction, aspects of visual and verbal memory, and executive functions in chronic, early‐onset schizophrenia patients (mean age = 20.7 years) (N = 18) and healthy controls (N = 38). Schizophrenia diagnoses were established at the time of the patients' first clinical presentation during childhood or adolescence and were confirmed five years later. In the chronic phase of early‐onset schizophrenia, significant deficits were observed in all specific cognitive functions. The profile of cognitive deficits was jagged, and visual‐construction, attention, and one aspect of verbal memory (verbal stories recall) were differentially impaired. Deficits of visual recall, visual recognition, and executive functions were accounted for by deficits in intelligence, while this was not the case for deficits of verbal recall of stories or attention. No significant associations were observed between the severity of cognitive deficits and that of depressive symptoms. Chronic, early‐onset schizophrenia is characterized by a broad and jagged profile of cognitive deficits. Deficits of attention and verbal recall of stories appear not to be accounted for by deficits in intelligence, and the severity of cognitive deficits seems independent from that of depressive symptoms     

Prevalence of auditory verbal hallucinations in a general population: A group comparison study

The present study was specifically designed to investigate the prevalence of auditory verbal hallucinations (AVH) in the general population, and sought to compare similarities and differences regarding socio‐demographics, mental health and severe life events between individuals who have never experienced AVH with those who had. The study also aimed to compare those who sought professional help for their experience of AVH with those who had not sought help. Through a postal questionnaire, 2,533 participants ages 18 and over from a national survey completed the Launay‐Slade Hallucinations Scale and other measures examining AVH characteristics and other areas related to AVH. In total, 7.3% of the sample reported a life‐time prevalence of AVH. Those with AVH were more likely to be single and unemployed, reported higher levels of depression and anxiety, and experienced a higher number of severe life events compared with those without AVH. Only 16% of those who experienced AVH in the general population sought professional help for these experiences. Compared to those who did not seek professional help, participants that had were more likely to experience AVH with a negative content, experience them on a daily basis, undergo negative reactions when experiencing AVH, and resist AVH. In conclusion, the prevalence of AVH was found to be relatively high. The results also revealed higher levels of reduced mental health for individuals who sought professional help, followed by those who did not, compared with those who had never experienced AVH.     

Social Welfare and the Psychology of Food Sharing: Short‐Term Hunger Increases Support for Social Welfare

Do politically irrelevant events influence important policy opinions? Previous research on social welfare attitudes has emphasized the role of political factors such as economic self‐interest and ideology. Here, we demonstrate that attitudes to social welfare are also influenced by short‐term fluctuations in hunger. Using theories in evolutionary psychology, we predict that hungry individuals will be greedier and take more resources from others while also attempting to induce others to share by signaling cooperative intentions and expressing support for sharing, including evolutionarily novel forms of sharing such as social welfare. We test these predictions using self‐reported hunger data as well as comparisons of subjects who participated in relevant online studies before and after eating lunch. Across four studies collected in two different welfare regimes—the United Kingdom and Denmark—we consistently find that hungry individuals act in a greedier manner but describe themselves as more cooperative and express greater support for social welfare.     

Early drinking onset: A study of prevalence and determinants among 13‐year‐old adolescents in Norway

Early drinking onset is associated with different psychosocial adjustment problems among adolescents. The aim of this study was to assess determinants associated with early drinking and to identify factors predicting early drinking onset among adolescents. The study included 1,550 eighth‐graders with a mean age of 13.5 years from 41 schools. A total of 24% (boys 29%, girls 19%) had ever drunk alcohol, while 14% had drunk some alcohol in the last 30 days. Further, early drinking was associated with gender, religion, school performance, smoking and bullying in the bivariate tests. Predictors of early drinking onset were identified by generalized linear mixed models with two multivariable models created. The first model included social and environmental variables. Entering intentions, expectancies, attitudes and norms into the multivariable analysis resulted in a significant improvement of the model fit constituting 86% in the second model. The percentage correctly classified those (56%) who had been drinking in the second model which was two times higher compared to the first model. Gender, religion and smoking emerged as significant predictors of drinking in both models.     

Is conscious perception gradual or dichotomous? A comparison of report methodologies during a visual task

In a recent article, [Sergent, C. &; Dehaene, S. (2004). Is consciousness a gradual phenomenon? Evidence for an all-or-none bifurcation during the attentional blink, Psychological Science, 15(11), 720–729] claim to give experimental support to the thesis that there is a clear transition between conscious and unconscious perception. This idea is opposed to theoretical arguments that we should think of conscious perception as a continuum of clarity, with e.g., fringe conscious states [Mangan, B. (2001). Sensation’s ghost—the non-sensory “fringe” of consciousness, Psyche, 7, 18]. In the experimental study described in this article, we find support for this opposite notion that we should have a parsimonious account of conscious perception. Our reported finding relates to the hypothesis that there is more than one perceptual threshold [Merikle, P.M., Smilek, D. &; Eastwood, J.D. (2001). Perception without awareness: perspectives from cognitive psychology, Cognition, 79, 115–134], but goes further to argue that there are different “levels” of conscious perception.     

Exposing the conjuring trick: Wittgenstein on subjectivity

Since the publication of the Philosophical Investigations in 1953, Wittgenstein's later philosophy of mind has been the subject of numerous books and articles. Although most commentators agree that Wittgenstein was neither a behaviorist nor a Cartesian dualist, many continue to ascribe to him a position that strongly resembles one of the alternatives. In contrast, this paper argues that Wittgenstein was strongly opposed to behaviorism and Cartesianism, and that he was concerned to show that these positions implicitly share a problematic assumption. This assumption is a seemingly innocent idea that subjectivity, or mind, is some kind of object or thing. The paper provides a detailed survey of Wittgenstein's critique of Cartesianism and behaviorism, as well as an outline of Wittgenstein's alternative account of subjectivity.     

Methodological individualism

The doctrine of methodological individualism is clarified and different versions of it are distinguished. The main thesis of the article is that methodological individualism is either a false doctrine or else a doctrine compatible with functionalism, structuralism, and Marxism. Positively it is maintained that, for all we know, collective entities such as power structures may shape our beliefs and values; these beliefs and values may explain some of our actions and expectations. These actions and expectations, together with similar actions and expectations of other people, caused in a similar fashion, may in turn constitute social phenomena. This means that, for all we know, in our best explanations of some social phenomena we may well need to have recourse to collective entities.
