The relation between smoking-specific parenting and smoking trajectories of adolescents: How are changes in parenting related to changes in smoking?

In this study, we tested to what extent smoking-specific parenting and changes in parenting are related to adolescents’ smoking trajectories. Data were used from a four-wave prospective study including 428 adolescents (aged M = 15.2; SD = 0.60). Latent Class Growth Analyses were conducted to identify trajectories. Multinomial Logistic Regression Analyses were executed to examine the relations between parenting and class membership. Longitudinal cross-lagged models were tested to examine causal predominance between parenting and smoking. Four trajectories were found, consisting of Non-smokers, Increasers, Stable smokers and Decreasers. Quality of parental smoking-specific communication was strongly related to the membership in different trajectories. Along with the cross-lagged associations demonstrating that the quality of communication was predominantly related to future smoking rather than vice versa, these findings indicate that parents who talked about smoking in a constructive and respectful manner were more likely to have non-smoking children. In contrast, parents who talked often about smoking-related issues and increased these discussions over time were more likely to have smoking children; cross-lagged associations indicated that these findings could be best explained by children changing their parents. Having a non-smoking agreement was related to a lower risk in becoming a regular smoker.     

Implications of attachment theory for working in psychoanalytic psychotherapy

John Bowlby's Attachment Theory is being increasingly operationalised in the world of developmental research, but as yet its implications for clinical work are relatively less discussed. This paper addresses the issue of the measurement of attachment patterns and how knowledge of these can inform psychoanalysts’ work with their patients. It looks at the implications of Attachment Theory at all stages of the therapeutic process, but concentrates particularly on how it can help with the crucial phase of building the working alliance.     

HIV-protection through condom use: Testing the theory of planned behaviour in a community sample of heterosexual men in a high-income country

Given the increasing importance of heterosexual HIV-transmission in Europe and Switzerland, the present study tested the theory of planned behaviour (TPB) in a prospective study on the HIV-protection behaviour in a community sample of heterosexual men. The study focused on condom use in sexual encounters with new partners. Participants were 982 Swiss men between the ages of 25 and 65 who were surveyed using standardised questionnaires in two computer-assisted telephone interviews that took place in autumn 2002 and spring 2003. The TPB was able to predict condom use in sexual encounters with new and casual partners. In accordance with the theory, condom use was predicted by intention. Perceived behavioural control and attitude were significant predictors of intention, whereas subjective norm was not. Thus, in line with other studies, the present study highlighted the somewhat limited explanatory power of the theory. Further theoretical and empirical work is needed to develop extensions to the theory.     

The effects of source trustworthiness and inference type on human belief revision

We investigated whether people revise their beliefs as a function of inference type or source trustworthiness. By doing so we aimed to find out if belief revision is better explained by mental model theory (Johnson-Laird & Byrne, 2002 Johnson-Laird, P. N. and Byrne, R. M. J. 2002. Conditionals: A theory of meaning, pragmatics, and inference. Psychological Review, 109: 211–228. [Crossref], [Web of Science ®] , [Google Scholar]) or by a conditional probability view (Evans, Handley, & Over, 2003 Over, D. E. and Evans, J. St. B. T. 2003. The probability of conditionals: The psychological evidence. Mind & Language, 18: 340–358. [Crossref], [Web of Science ®] , [Google Scholar]; Oaksford & Chater, 2001 Oaksford, M. and Chater, N. 2001. The probabilistic approach to human reasoning. Trends in Cognitive Science, 5: 349–357. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). We used modified modes ponens (MP) and modus tollens (MT) problems in which the first two premises were uttered by persons with varying degrees of trustworthiness. A third statement was presented as a fact and established inconsistency in the set of propositions. The participants' task was to indicate which of the first two premises they believed more after receiving the fact. We found that the belief in the conditional premise dropped significantly when this premise was stated by a low- rather than a high-trustworthy source. Moreover we found that the conditional premise was believed more in MT than in MP problems. Both findings are best explained by the conditional probability hypothesis (e.g., Evans et al., 2003 Evans, J. St. B. T., Handley, S. J. and Over, D. E. 2003. Conditionals and conditional probability. Journal of Experimental Psychology: Learning, Memory, and Cognition, 29, : 321–335. [Crossref] , [Google Scholar]).     

Is the truth table task mistaken?

There is ample evidence that in classical truth table task experiments false antecedents are judged as “irrelevant”. Instead of interpreting this in support of a suppositional representation of conditionals, Schroyens (2010a Schroyens, W. 2010a. Mistaking the instance for the rule: A critical analysis of the truth-table evaluation paradigm. Quarterly Journal of Experimental Psychology, 63: 246–259. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar], 2010b Schroyens, W. 2010b. A meta-analytic review of thinking about what is true, possible, and irrelevant in reasoning from or reasoning about conditional propositions. European Journal of Cognitive Psychology, 22: 897–921. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) attributes it to the induction problem: the impossibility of establishing the truth of a universal claim on the basis of a single case. In the first experiment a truth table task with four options is administered and the correlation with intelligence is inspected. It is observed that “undetermined” is chosen in one third of the judgements and “irrelevant” in another third. A positive correlation is revealed between intelligence and the number of “irrelevant” and “undetermined” judgements. The data do not exclude that a part of the “irrelevant” judgements in classical truth table task experiments might be caused by the induction problem. In the second experiment participants are presented with a simplified four-option truth table task and asked for a justification of their judgements. These justifications show the induction problem is not the reason for choosing the “irrelevant” or “undetermined” option, which is supportive for a suppositional representation of conditionals.     

Divergent viewpoints about lineups: What policy for the identification of criminals?

IntroductionA fair lineup is needed to maximize the likelihood of correct identification of the criminal and minimize the likelihood of mistaken identification. Fairness depends on distractor plausibility and the lineup method (i.e., simultaneous or sequential).ObjectiveThis paper aims to evaluate the advantages and the limits of distractor plausibility and the presentation of the lineup members, and thus show the best method to ensure correct identification.MethodOur conclusions are based on the major experiments published in the field and on recent debates in the scientific community.Results and conclusionIn addition to distractor plausibility, our conclusions, which are based on previous work by Malpass (2006), suggest that sequential and simultaneous lineups are complementary rather than opposed. The paper argues that two tools specifically designed for and adapted to particular situations are better than one.     

How Much Older Do You Get When a Wrinkle Appears on Your Face? Modifying Age Estimates by Number of Wrinkles

ABSTRACT

The present study investigated the influence of wrinkles on facial age judgments. In Experiment 1, preadolescents, young adults, and middle-aged adults made categorical age judgments for male and female faces. The qualitative (type of wrinkle) and quantitative (density of wrinkles and depth of furrows) contributions of wrinkles were analyzed. Results indicated that the greater the number of wrinkles and the depth of furrows, the older a face was rated. The roles of the gender of the face and the age of the participants were discussed. In Experiment 2, participants performed relative age judgments by comparing pairs of faces. Results revealed that the number of wrinkles had more influence on the perceived facial age than the type of wrinkle. A MDS analysis showed the main dimensions on which participants based their judgments, namely, the number of wrinkles and the depth of furrows. We conclude that the quantitative component is more likely to increase perceived facial age. Nevertheless, other variables, such as the gender of the face and the age of the participants, also seem to be involved in the age estimation process.     

Group work in general practice

In this article, consideration is given to a problem often experienced in relation to courses offering psychodynamic understanding to front-line workers with troubled clients – the complexity for the student in taking the learning ‘home’ in a productive manner and the potential isolation of the student in, or alienation from, their workplace. A model of course delivery is described in which an active three-way partnership between student, course and workplace is fostered which enhances the students' learning, enables the workplace to benefit more fully from the course and enhances the effectiveness of the course in improving service to the ultimate client – the service user.     

Ecclesiological Research and Natural and Human Sciences: Some Observations of an Unconventional Phenomenon

This article is motivated by the absence of published material dealing with the rapprochement between ecclesiology and the sciences. It presupposes that there is a need to broaden the scope of ecclesiological research in order to integrate into it theories and methods from the social and natural sciences. Ecclesiological research in this wider sense has as its object, church, as a broad concept. The article suggests a threefold aspect for ecclesiology, conceiving it as the ecclesiology of the researcher, and the ecclesiology of both the object and of the result of the research. Furthermore, its purpose is to identify transparent ecclesiological theories which are able to engage with and integrate scientific theories and methods. An inventory of examples of modes of collaboration used between ecclesiology and different sciences is then offered as an illustration of the context in which ecclesiology may integrate or relate to science in different ways. Finally, the article concludes that there is a need for further clarificatory research into the possibilities which exist for ecclesiology to be made more fully the science of being Christian in community or church.     

Conditional estimation of exponential random graph models from snowball sampling designs

A complete survey of a network in a large population may be prohibitively difficult and costly. So it is important to estimate models for networks using data from various network sampling designs, such as link-tracing designs. We focus here on snowball sampling designs, designs in which the members of an initial sample of network members are asked to nominate their network partners, their network partners are then traced and asked to nominate their network partners, and so on. We assume an exponential random graph model (ERGM) of a particular parametric form and outline a conditional maximum likelihood estimation procedure for obtaining estimates of ERGM parameters. This procedure is intended to complement the likelihood approach developed by  Handcock and Gile (2010) by providing a practical means of estimation when the size of the complete network is unknown and/or the complete network is very large. We report the outcome of a simulation study with a known model designed to assess the impact of initial sample size, population size, and number of sampling waves on properties of the estimates. We conclude with a discussion of the potential applications and further developments of the approach.
