Direction of Effects in Multiple Linear Regression Models

Previous studies analyzed asymmetric properties of the Pearson correlation coefficient using higher than second order moments. These asymmetric properties can be used to determine the direction of dependence in a linear regression setting (i.e., establish which of two variables is more likely to be on the outcome side) within the framework of cross-sectional observational data. Extant approaches are restricted to the bivariate regression case. The present contribution extends the direction of dependence methodology to a multiple linear regression setting by analyzing distributional properties of residuals of competing multiple regression models. It is shown that, under certain conditions, the third central moments of estimated regression residuals can be used to decide upon direction of effects. In addition, three different approaches for statistical inference are discussed: a combined D’Agostino normality test, a skewness difference test, and a bootstrap difference test. Type I error and power of the procedures are assessed using Monte Carlo simulations, and an empirical example is provided for illustrative purposes. In the discussion, issues concerning the quality of psychological data, possible extensions of the proposed methods to the fourth central moment of regression residuals, and potential applications are addressed.     

Varying the response code in the blindness to response-compatible stimuli

Previous work has indicated that action-control processes can specifically influence perceptual processes. The identification of a left- or right-pointing arrow is impaired when it appears during the preparation and execution of a compatible left-right keypress (Müsseler & Hommel, 1997a, b). The present study examines the role of the response-specifying cue in order to manipulate the coding of the action-control processes. Experiment 1 shows that the size of the perceptual impairment is not affected by whether the cue has high or little feature overlap with the to-be-performed response. Cues were omitted in Experiment 2 and participants generated their responses endogenously, but the perceptual impairment still occurred. Experiment 3 examines in more detail which feature of the response contributes to the effect. The results show that it needs both an intended action goal and a corresponding motor activity to bring about the perceptual impairment.     

The real trouble with intentionality

I argue that the project of naturalizing intentionality is misconceived. Intentionality should not be considered as a challenge to our naturalistic world-view, but rather as something which gives rise to a logical problem: how to save the principle of indiscernibility of identicals from apparent counterexamples arising from intensional discourse.     

Editorial Political Cartoons in Australia: Social Representations & and the Visual Depiction of Essentialism

Six million migrants from over 170 countries have resettled in Australia since 1945 ensuring religious diversity is now a hallmark of Australia’s population. However, not all religious groups are perceived in the same way. In this paper, we explore how representational processes differentially essentialise religious groups, in particular how some groups are ascribed an underlying nature that irrevocably defines who they are and how they will behave, whilst other groups are conveyed merely as coherent entities with similarity in goals and structure. We elucidate this through an analysis of the depiction of religious markers in Australian Editorial political cartoons. We mirror the near-exclusive focus on the Muslim and Christian religions, in the religious cartoons we sampled, to present an analysis of 6 exemplar cartoons. Drawing from visual analysis techniques (van Leeuwen 2001) and social representations theory (Moscovici 1984) we highlight how essentialist perceptions of religious groups are unwittingly fostered in everyday media communications. We discuss the implications of our analysis for the transnationalisation of religion.     

Movement-based compatibility in simple response tasks

Previous studies reported that movement observation affected movement execution. Using one and the same set of responses (i.e., lifting or tapping the finger), correspondence effects were observed for simple responses when the go-signals were similar to the responses (i.e., movies of finger movements) but not when they were dissimilar (i.e., moving squares). The difference was attributed to a higher degree of ideomotor compatibility with visible limb movements. We tried to provide further evidence for ideomotor theory by manipulating the degree to which different responses matched one and the same set of stimuli (drifting sine-wave gratings). To this end, we measured simple reaction time of dynamic (hand movements) or static (key presses) movements in response to the onset of object motion. Object motion and dynamic responses showed ideomotor compatibility without looking alike; however, both stimulus and response involved continuous displacements. Correspondence effects were observed for dynamic responses, but not for static responses.     

Burn-out

At first the concept of burnout will be critically reflected in the context of the discussion in a position paper of the German Society for Psychiatry Psychotherapy and Neurology. An investigation of preventive stress management interventions at the workplace will be reported. The treatment concept of the day clinic of the Department for Psychosomatic Medicine and Psychotherapy of the Munich-Harlaching hospital for occupational stress-related disorders will be presented. An empirical study of the effectiveness of this treatment will be reported comparing patients with occupational stress-related disorders (n?=?95) to other patients treated in the day clinic during the same time interval (n?=?154). Furthermore, a qualitative analysis of 102 patient charts with occupational stress-related disorders will be described. Two case histories typical for mental health disease with burnout syndrome are presented to illustrate the conclusions.     

Doubts about One’s Own Existence

The aim of this paper is to show that it is not irrational to doubt one’s own existence, even in the face of introspective evidence to the effect that one is currently in a certain mental state. For this purpose, I will outline a situation in which I do not exist, but which cannot be ruled out on the basis of any evidence available to me—including introspective evidence about my current mental states. I use this ‘superskeptical scenario,’ as I will call it, to formulate an argument to the conclusion that I do not know that I exist. In order to substantiate my argument, I draw upon Terence Parsons’ theory of non-existent objects. I conclude that, inasmuch as Parsons’ theory is reasonable, doubts about one’s own existence are reasonable as well.     

Warning: You are being primed! The effect of a warning on the impact of subliminal ads

As it has been demonstrated that subliminal advertising can affect consumers' decisions – if the ad is goal relevant – the question rises whether consumers are able to shield themselves from subliminal influences. In the present research it was examined whether warning people of the presence of subliminal ads could decrease subliminal advertising effects. In Study 1, it was demonstrated that warning people of subliminal ads indeed diminished priming effects on consumer choice, whereas subliminal advertising effects were replicated for people who were not warned (i.e., people for whom the primed brand was goal relevant were more likely to select it when primed). Study 2 extended these findings, revealing that both participants warned before and after the priming manipulation were less influenced by subliminal brand primes than controls. This suggests that the warning does not decrease participants' sensitivity to the prime, but instead affects the influence of the prime at the behavioral level. Several explanations and implications are discussed.     

Understanding dieting: A social cognitive analysis of hedonic processes in self-regulation

The present paper introduces a novel approach to understanding failures of self-regulation in chronic dieters. Traditional approaches to this problem have focused on consciously controlled processes of eating regulation, such as the realisation that one has overeaten, or the experience of food cravings. We argue, however, that dieters' problem might rather lie in their sensitivity to the hedonic aspects of food and the resulting inhibition of their dieting goal. We present a goal-conflict model that integrates recent findings on hedonic sensitivity in eating regulation with social cognition research on nonconscious goal pursuit. We show that the perception of attractive food triggers hedonic thoughts about food in chronic dieters and leads to the inhibition of their dieting goal. These processes make subsequent overeating more likely, while bypassing dieters' conscious awareness. We discuss how our model can accommodate earlier research findings in this area, and we consider its implications for dieting behaviour and for our attempts to resist temptations more generally.     

Cross‐cultural evidence of value structures and priorities in childhood

We broaden the developmental focus of the theory of universals in basic human values (Schwartz, 1992, Advances in Experimental Social Psychology) by presenting supportive evidence on children's values from six countries: Germany, Italy, Poland, Bulgaria, the United States, and New Zealand. 3,088 7–11‐year‐old children completed the Picture‐Based Value Survey for Children (PBVS‐C, Döring et al., 2010, J. Pers. Assess., 92, 439). Grade 5 children also completed the Portrait Values Questionnaire (PVQ, Schwartz, 2003, A proposal for measuring value orientations across nations. Chapter 7 in the Questionnaire Development Package of the European Social Survey). Findings reveal that the broad value structures, sex differences in value priorities and pan‐cultural value hierarchies typical of adults have already taken form at this early age. We discuss the conceptual implications of these findings for the new field of children's basic values by embedding them in the recent developmental literature.
