Affect intensity contributes to perfectionistic self-presentation in adolescents beyond perfectionism

Perfectionistic self-presentation in adolescents is associated with psychological maladjustment and distress. Yet, no study so far has investigated what personality characteristics contribute to perfectionistic self-presentation in adolescence. Using a cross-sectional correlational design with 119 adolescents aged 11-16 years, this study investigated how perfectionism (self-oriented and socially prescribed perfectionism) and affect intensity (positive affectivity, negative intensity, and negative reactivity) predicted individual differences in three modes of perfectionistic self-presentation: perfectionistic self-promotion, nondisplay of imperfection, and nondisclosure of imperfection. Results showed a unique prediction pattern for all three modes of perfectionistic self-presentation. Moreover, affect intensity contributed to perfectionistic self-presentation beyond perfectionism in two of the three modes: Perfectionistic self-promotion was predicted by high self-oriented perfectionism, high socially prescribed perfectionism, high positive affectivity, and low negative reactivity. In contrast, nondisplay of imperfection was predicted by high self-oriented perfectionism, high negative reactivity, and low positive affectivity. Nondisclosure of perfectionism was predicted by high socially prescribed perfectionism only. The findings suggest that affect intensity is a personality characteristic contributing to perfectionistic self-presentation in adolescence beyond perfectionism

Searching for inhibition of return in the rat using the covert orienting of attention task

Inhibition of return (IOR) is an important psychological construct describing inhibited responses to previously attended locations. In humans, it is investigated using Posner’s cueing paradigm. This paradigm requires central visual fixation and detection of cued stimuli to the left or right of the fixation point. Stimuli can be validly or invalidly cued, appearing in the same or opposite location to the cue. Although a rat version of the spatial cueing paradigm (the covert orienting of attention task) does exist, IOR has so far not been demonstrated. We therefore investigated whether IOR could be robustly demonstrated in adult male rats using the covert orienting of attention task. This task is conducted in holed wall operant chambers with the central three holes mimicking the set-up for Posner cueing. Across four samples of rats (overall n = 84), we manipulated the following task parameters: stimulus onset asynchronies (Experiments 1–3), cue brightness (Experiment 1b) and the presence of a central reorienting event (Experiment 4). In Experiment 1, we also investigated strain differences by comparing Lister Hooded rats to Sprague–Dawley rats. Although Lister Hooded rats briefly showed evidence of IOR (Experiment 1a, and see Online Resource 1 data), we were unable to replicate this finding in our other experiments using different samples of this strain. Taken together, our findings suggest that IOR cannot be robustly demonstrated in the rat using the covert orienting of attention task conducted in holed wall operant chambers
