Comparing latent distributions

We consider the problem of comparingm latent population distributions when the observed values are scores on a test battery with binary items. The latent densities are assumed to be normal densities, and we consider a test for equality of the means as well as a test equality of the variances. In addition, we consider a longitudinal model, where the test battery has been applied to the same individuals at different points in time. This model allows for correlations between the latent variable at different time points, and methods are discussed for estimating the correlation coefficient.This work was supported in part by a grant from the Danish Social Science Research Council.     

COVID-19 and Its Lockdown in Belgium: How Limited Access to Environmental Satisfaction Impacts Emotions?

The COVID-19 pandemic has been shown to induce several psychological consequences (e.g., increases in anxiety and stress). Accordingly, it seems relevant to investigate how individuals cope with their emotions. Indeed, when facing negative emotions, individuals need to rely on adaptive emotion regulation strategies to alleviate their negative impacts (e.g., decrease in quality of life, increase in sleep disturbances). Moreover, lockdown’s measures led to a restriction of the access to activities which, in turn, might have decreased the “environmental satisfaction”. Then, this research investigates the pandemic’s psychological impacts on emotions and regulation strategies, intolerance of uncertainty, and environmental satisfaction. Our approach’s originality relies on comparing one’s actual psychological functioning (i.e., since the pandemic) to one’s general psychological functioning (i.e., before the pandemic). This study also assesses the relationships between both negative and positive emotions and (1) emotion regulation strategies, (2) intolerance of uncertainty and, (3) environmental satisfaction since the pandemic and its lockdown. The total sample comprised 948 adults from the general population. Results show that, since the pandemic, individuals experience higher levels of negative emotions, lower levels of positive emotions and environmental satisfaction. They also tend to worry less and to resort to acceptance more often. Also, environmental satisfaction is the most important predictor of both negative emotions and positive ones. Overall, findings confirm previous ones and seem to indicate that environmental satisfaction should be addressed more thoroughly.     

Sex-role typing as related to acceptance of self, acceptance of others, and discriminatory attitudes toward women

This study examines four hypotheses relating sex-role typing to self-acceptance, acceptance of others, and sexist attitudes toward women. University students completed the Bem Sex-Role Inventory, the Berger Self-Acceptance Scale, and the Macho Scale. Findings showed more self-acceptance than acceptance of others among masculine-typed subjects and more acceptance of others than self-acceptance among feminine-typed subjects. Feminine-typed males and masculine-type females showed least self-acceptance among the six groups, while androgynous subjects showed highest self-acceptance. Masculine-typed males were least accepting of others and scored highest in discriminatory attitudes toward women. Male subjects showed greater variability than did female subjects on all scales, and Bem's measure of sex-role typing proved a more efficient moderator of scores of males than of those of females. Additional personality and behavioral research with sex-role typing variables is proposed.     

Interpersonal feedback in everyday life: Empirical studies in Germany and the United States

The present research examines occurrences of interpersonal feedback in everyday life. Drawing upon retrospective self-reports from three student samples in Germany and the US, we investigate why, how, and with what effect such feedback is shared. We found that feedback was common, occurring mostly within stable interpersonal relationships, and that positive feedback was reported to occur more often than negative feedback. Positive and negative feedback was provided to achieve different goals (acknowledgement vs. behavioral change), and feedback senders perceived negative feedback as less successful than positive feedback. Negative feedback was withheld primarily when potential senders perceived it as futile or potentially dangerous to their relationship with the recipient. However, negative feedback that was shared was not seen as particularly harmful in that regard. We discuss potential barriers to feedback effectiveness, whether and how the exchange of interpersonal feedback in everyday life may be promoted, and give recommendations for future research.     

Does Attention Modulate the Perception of Luminance Changes?

In a previous study assessing the modulation of visual processing by attention, Bonnel, Possami, and Schmitt showed that, when discriminating line-length, subjects precisely shared processing resources between two pairs of lines presented to the left and right of fixation. In a close replication requiring the detection of luminance increments instead of line-length differences, subjects were unable to follow the instructions and to allocate attention differentially, thus supporting the claim that light detection is fundamentally different from shape discrimination. In a subsequent experiment, we tested and rejected the possibility that luminance perception was not open to modulation by attention due to its physical nature. Replacing brightness detection by brightness identification allowed voluntary control on the quality of processing to be evidenced. The similarity between the latter results and the data from line-length discrimination suggests that task requirements may be crucial in determining the distribution of attention.     

Syllogistic reasoning and belief-bias inhibition in school children: evidence from a negative priming paradigm

Research on deductive reasoning in adolescents and adults has shown that errors in deductive logic are not necessarily due to a lack of logical ability but can stem from an executive failure to inhibit biases. Few studies have examined this dissociation in children. Here, we used a negative priming paradigm with 64 children (8-10 years old) to test the role of cognitive inhibition in syllogisms with belief-bias effects. On trials where negative priming was predicted, results were as follows: For the first syllogism (A), the strategy 'unbelievable-equals-invalid' had to be inhibited. The logic of the syllogism led to affirming a conclusion inconsistent with one's knowledge of the world, such as 'All elephants are light.' For the second syllogism (B), one's real-world knowledge and the syllogism's logic were congruent but the latter required affirming exactly what had been inhibited for A (i.e. that elephants are heavy). A negative priming effect on the A-B sequence was reflected in a significant drop in reasoning performance on B. This supports the idea that during cognitive development, inhibitory control is required for success on syllogisms where beliefs and logic interfere.     

Theological Ethics, Moral Philosophy, and Natural Law

The article deals with the relationship between theological ethics and moral philosophy. The former is seen as a theoretical reflection on Christian ethics, the latter as one on secular ethics. The main questions asked are: (1) Is there one and only one pre-theoretical knowledge about acting rightly? (2) Does philosophy provide us with the theoretical framework for understanding both Christian and secular ethics? Both questions are answered in the negative. In the course of argument, four positions are presented: theological ‘unificationism’, philosophical ‘unificationism’, theological ‘separationism’ and Lutheran ‘dualism’. It is argued that the latter position is most convincing. It is dual in the sense of being both a theory of Christian ethics and of including a recognition of natural law. Hence, it unites a particularistic and a universalistic point of view. In the last section a reformulation of the Lutheran position is attempted in making use of the ethical theory of Knud E. Løgstrup's The Ethical Demand.     

Identity and expression memory for happy and angry faces in social anxiety

We examined the influence of social anxiety on memory for both identity and emotional expressions of unfamiliar faces. Participants high and low in social anxiety were presented with happy and angry faces and were later asked to recognise the same faces displaying a neutral expression. They also had to remember what the initial expressions of the faces had been. Remember/know/guess judgements were asked both for identity and expression memory. For participants low in social anxiety, both identity and expression memory were more often associated with "remember" responses when the faces were previously seen with a happy rather than an angry expression. In contrast, the initial expression of the faces did not affect either identity or expression memory for participants high in social anxiety. We interpreted these findings by arguing that most people tend to preferentially elaborate positive rather than negative social stimuli that are important to the self and that this tendency may be reduced in high socially anxious individuals because of the negative meaning they tend to ascribe to positive social information.
