Individual differences and changes in personality during the COVID-19 pandemic

This article reports the results of an eleven-wave longitudinal study of personality change conducted between December 2019 and December 2022 with 1328 participants in Germany. Based on theories of personality change, we investigated trajectories of big five personality factors (i.e., extraversion, agreeableness, conscientiousness, emotional stability, and openness) across the COVID-19 pandemic. In addition, we examined whether demographic characteristics (i.e., age, sex), self-reported health status (i.e., physical, mental), and socioeconomic status (i.e., education, income, industry) moderated these trajectories. There was evidence for increases in extraversion, conscientiousness, and emotional stability and decreases in openness across time. The magnitude of these effects suggests between d = 0.027 to 0.138 standard deviation changes in these personality characteristics across the 3-year timeframe of this study. Evidence for moderating effects of age, sex, health, and socioeconomic status was mixed, but indicates differential patterns of personality change for certain individuals. Overall, findings suggest that changes in big five personality factors across the COVID-19 were present, albeit on average relatively weak, but still higher than anticipated given the timeframe. Moreover, certain demographic and health variables were associated with differential trajectories of personality over time.     

A Cognitive-Interpersonal Approach to Depressive Symptoms in Preadolescent Children

Cognitive and interpersonal aspects of depressive symptoms were investigated in a community sample of children. Eighty-one 8- to 12-year-olds completed scales assessing cognitive representations of social relationships and symptoms of depression and anxiety. Teachers provided ratings of peer rejection. Children with elevated levels of depressive symptoms displayed increased negativity in their beliefs about self, family, and peers, as well as distinct patterns of interpersonal information processing. Anxiety symptoms did not make a unique contribution beyond depression to negative representations of family and peers; in contrast, symptom-specific profiles of self-representations were found. Structural equation analysis supported a model linking negative interpersonal representations, peer rejection, and depressive symptoms. The findings suggest that future studies may benefit from approaches that incorporate both cognitive and interpersonal variables as predictors of child depression.     

A survey of attitudes concerning contraception and the resolution of teenage pregnancy

This study reports the results of a survey of 498 respondents in a large midwestern community concerning their attitudes toward making contraceptive services available to teenagers and the manner in which a teenage pregnancy should be resolved. The results indicated that the large majority of respondents approved of the practice of making contraceptives available to teenagers but there were also significant differences in attitudes expressed which were dependent upon demographic characteristics of the respondent. There was also considerable variability in the attitudes expressed concerning the resolution of a teenage pregnancy. The preferred method of resolution depended again on the demographic characteristics of the respondent. Keeping the baby and placing the baby for adoption were the most frequent choices. These results are discussed with relation to the present strong political conservative movement in the nation.     

Auditory stimulus control in pigeons: Jenkins and Harrison (1960) revisited

Pigeons were trained to peck a key in the presence of a 1000-Hz tone on a variable-interval one-minute schedule of reinforcement. One group was trained with an illuminated key; the other was trained in a totally dark chamber. During a generalization test on tonal frequency, subjects trained and tested with the key illuminated produced rather shallow gradients around the training value; subjects trained and tested in the dark produced steeper generalization gradients. These data replicate Jenkins and Harrison's (1960) finding that tone acquires relatively little control over responding and demonstrate that this absence of control is a function of the presence of the keylight.     

Effects of monochromatic rearing on spectral discrimination learning and the peak shift in chicks

Chicks were hatched and raised in white or monochromatic sodium (589 nm) light. They were trained on a 590 (+) vs. 580 (-) nm successive discrimination. The combined results of two experiments indicated that rearing illumination did not affect discrimination acquisition. All subjects given generalization tests after discrimination training exhibited peak shifts that were equivalent for the two rearing conditions. The peak shifts exhibited by the monochromatically reared subjects represent maximum responding to stimuli they had not previously seen. This result further confirms the notion that behavioral control by the spectral dimension in birds is organized independently of differential early experience on that dimension.     

The Finite-Dimensional Freeman Thesis

I suggest a modification—and mathematization—of Freeman’s thesis on the relations among “perception”, “the finite brain”, and “the world”, based on my recent proposal that the theory of finite topological spaces is both an adequate and a natural mathematical foundation for human psychology.

What are the mechanisms? The black box of neoliberalism

In this response to Bal and Doci's (2018) commentary on neoliberal ideology in work and organizational psychology (Bal, P. M., & Dóci, E. (2018)). Neoliberal ideology in work and organizational psychology. European Journal of Work and Organizational Psychology. Online first publication, https://doi.org/10.1080/1359432X.2018.1449108), we argue that neoliberalism can only be a distal exogenous influence on psychological processes. It remains unclear which mechanisms might translate this ideology into work and organizational psychology science and practice. Researchers need to move beyond black box explanations and provide clarity about the nature of concepts, how they manifest, and the mechanisms that translate ideology into psychological phenomena.     

Talking about appearances: the roles of evaluation and experience in disagreement

Faultless disagreement and faultless retraction have been taken to motivate relativism for predicates of personal taste, like ‘tasty’. Less attention has been devoted to the question of what aspect of their meaning underlies this relativist behavior. This paper illustrates these same phenomena with a new category of expressions: appearance predicates, like ‘tastes vegan’ and ‘looks blue’. Appearance predicates and predicates of personal taste both fall into the broader category of experiential predicates. Approaching predicates of personal taste from this angle suggests that their relativist behavior is due to their experience-sensitivity, rather than their evaluative meaning. Furthermore, appearance predicates hold interest beyond what they can teach us about predicates of personal taste. Examination of a variety of uses of appearance predicates reveals that they give rise to relativist behavior for a variety of reasons—including some that apply also to other types of expressions, such as epistemic modals and comparative terms. This paper thus serves both to probe the source of relativist behavior in discourse about personal taste, as well as to map out this kind of behavior in the rich and under-explored discourse about appearances.
