In evaluative conditioning, a neutral conditional stimulus (CS) acquires the valence of a pleasant or unpleasant unconditional stimulus (US) after the CS and US are paired (acquisition). Valence acquired by the CS can generalise to other stimuli from the same category. Presenting the CS alone can reduce evaluative conditioning (extinction), but evaluations can return after the US is presented alone (reinstatement). The current research investigated whether extinction and reinstatement generalise to other category members (generalisation stimuli, GS). In Experiment 1, evaluations generalised in acquisition after conditioning with one category exemplar, but GS evaluations were unaffected by extinction and reinstatement. In Experiment 2, we aimed to enhance generalisation by presenting multiple category exemplars during conditioning. This strengthened the generalisation of evaluations in extinction but not reinstatement. In Experiment 3, conditioning with multiple exemplars caused explicit and implicit evaluations (measured using an affective priming task) to generalise in acquisition but not in extinction or reinstatement. The acquisition and extinction of US expectancy generalised in all experiments, but the reinstatement generalised in Experiment 3 only. Overall, we found partial evidence of evaluative generalisation during extinction (but not reinstatement) and demonstrated that the extinction and reinstatement of US expectancy generalises in evaluative conditioning.

Emojis are frequently used in digital communication to supplement the lack of non-verbal cues, but their integration during reading has not been thoroughly examined. This study explores the interplay between language and emotion by testing the influence of emotional valence and face-status of emojis on visual word recognition. Two online experiments were conducted with 92 native English-speaking university students, examining priming effects between congruent (e.g. [Formula: see text] delicious) and incongruent (e.g. [Formula: see text] hate) prime-target pairs, varying the face-status of the emoji prime (face vs. non-face) and the valence (positive vs. negative) of the word target. Irrespective of valence, face emojis demonstrated a processing advantage over non-face emojis, implying automatic attention capture. Additionally, the results revealed an interaction between prime-target congruency and valence, with a facilitatory effect for positive, but not negative, items, suggesting a valence-specific mechanism of affective priming in the lexical decision task. The research suggests that the rapid integration of emoji content occurs during the early stages of visual word recognition, with heightened attentional sensitivity to both face-like and positive stimuli when reading digital communications.

The current study explores the differences in conceptualisation of the prototypical basic emotion lexicalisations (anger, disgust, fear, joy, sadness, surprise) in English and in Polish. Measures of concreteness, imageability and context availability were collected and analysed across the six semantic categories of basic emotions, across different parts of speech and between the self-determined genders of the study participants. The initial results indicate that within these cognitive dimensions the conceptualisations of basic emotions in English and in Polish are only similar on the more general but not the higher levels of conceptualisation. The folk-psychological division between positive and negative emotions and the grammatical parts of speech reveal similar patterns in basic emotion concepts in both Polish and in English. However, on the higher levels of conceptualisations that include specific basic emotion semantic categories and self-identified gender, marked language-specific differences become apparent. Different negative emotions drive the statistical differences in Polish and in English, and the gender effects on the measures of concreteness, imageability and context availability are opposite from one language to the other. In other words, basic emotions may be broadly mutually intelligible, but not exactly the same when communicated across languages and cultures.

The ability to notice and reflect on distressing internal experiences from an objective perspective, often called psychological decentering, has been posited to be protective against mental health difficulties. However, little is known about how this skill relates to age across adolescence, its relationship with mental health, and how it may impact key domains such as affective executive control and social cognition. This study analysed a pre-existing dataset including mental health measures and cognitive tasks, administered to adolescents in Greater London and Cambridge (mean age (SD) = 14.4 (1.77) years, N = 553). A self-report index of decentering based on available questionnaire items in the dataset was developed. Multiple linear regression was used to examine associations between decentering and mental health, affective executive control (measured using an affective Stroop Task, affective Working Memory Task, and affective Sustained Attention to Response Task) and social cognition. Higher decentering was significantly associated with lower depression and anxiety scores and higher psychological wellbeing. Results did not indicate significant relationships between decentering, affective executive control and social cognition. Further research is needed to discover cognitive mechanisms associated with this process, which could allow for optimisation of existing psychological therapy and reveal new avenues of intervention.

Anhedonia, or a deficit in the liking, wanting, and seeking of rewards, is typically assessed via self-reported "in-the-moment" emotional and motivational responses to reward stimuli and activities. Given that mental imagery is known to evoke emotion and motivational responses, we conducted two studies to investigate the relationship between mental imagery use and self-reported anhedonia. Using a novel Reward Response Scale (adapted from the Dimensional Anhedonia Rating Scale, DARS; Rizvi et al., 2015) modified to assess deliberate and spontaneous mental imagery use, Study 1 (N = 394) compared uninstructed and instructed mental imagery use, and Study 2 (N = 586) conducted a test of replication of uninstructed mental imagery use. Results showed that greater mental imagery use was associated with higher reward response scores (Study 1 & 2), and this relationship was not moderated by whether imagery use was uninstructed or instructed (Study 1). Importantly, mental imagery use moderated the convergence between reward response and depression scale measures of anhedonia, with lower convergence for those reporting higher mental imagery use (Study 1 & 2). Results suggest that higher spontaneous mental imagery use may increase self-reported reward response and reduce the convergence between reward response scale and depression questionnaire measures of anhedonia.

Pride has rarely been explored in the context of moral disengagement and unethical decision-making. Although some research has examined the associations between "authentic" and "hubristic" pride and unethical behaviour, little attention has been paid to potential mechanisms. Across two correlational studies (N = 379), we explore the associations between two facets of pride rooted on comparisons - social comparison-based pride, and self-based pride, moral disengagement, and unethical decision-making. Results show that social comparison-based pride consistently (positively) relates to moral disengagement, and that moral disengagement accounts for the association between social comparison-based pride and unethical decision-making. In sum, our findings contribute in novel ways to the understanding of how pride based in different comparison frames may lead to antisocial decision-making.

Working memory capacity (WMC) refers to the ability to maintain information in short-term memory while attending to the immediate environment, and has been associated with emotional states. Yet, research on the link between WMC and emotion in naturalistic settings is growing and inconsistencies have been observed. In the current study (N = 109), we directly replicated the procedures of a prior experience sampling study (Garrison & Schmeichel, 2022), which found that higher WMC attenuates the relationship between stressful events in daily life and negative affect. We measured WMC in the laboratory and then measured the occurrence of stressful events, momentary emotional states, and coping responses to stress several times a day for six days. Higher WMC was associated with reduced momentary negative emotion, but this relationship did not depend on the occurrence of a stressful event. Exploratory analyses found that higher WMC was associated with a greater likelihood of planning as a coping response to stress and greater number of coping strategies reported per stressful event. However, coping did not mediate the link between WMC and momentary negative emotion. Our results contribute to the robustness and ecological validity of the link between WMC and reduced negative emotion in daily life.

Emotional false memory findings using the DRM paradigm have been marked by higher false alarms to negatively arousing compared to neutral critical lure items. Explanations for these findings have mainly focused on false memory-based accounts. However, here we address the question of whether a response bias for emotional stimuli can, at least in part, explain this phenomenon. Participants viewed both neutral and negative arousing DRM lists and completed a recognition test in speeded or self-paced conditions. Speeded test reduces the opportunity to adjust response bias. Analysis showed no significant difference in false recognition across critical lure types for the speeded condition, but false recognition was higher for negative compared to neutral critical lures in the self-paced condition. We argue that when retrieval does not allow for shifts in response criteria, false alarms to negative emotional critical lures appear more similar to neutral equivalents. The discussion explores memory-based and criterion-shift explanations for the enhanced emotional false memory finding.

Repetitive thinking is a common phenomenon, also implicated in a variety of mental disorders. The content of repetitive thoughts can take the form of prediction of aversive events (in worry) or evoking negatively valenced information (in rumination), for instance. Investigating the influence of repetitive thinking through the lens of associative learning could help deepen our understanding of the mechanisms involved in its effects.In two experiments, non-clinical participants were exposed to CS-US pairings with the aim of creating non-threatening expectancy learning (Experiment 1) or evaluative conditioning (Experiment 2). After each conditioning trial, participants were instructed to initiate repetitive thoughts about the pairing (i.e. rehearse) or follow control instructions.Experiment 1 (N = 64) showed that such intervention strengthen the association between the mental representations of the CS and the US, leading to a stronger US expectancy in response to the CS. In Experiment 2 (N = 107), an evaluative conditioning effect was observed; however, it was not influenced by instructions.The study demonstrated that simulated repetitive thinking strengthens the CS-US association and leads to greater US expectancy in expectancy learning, despite appearing not to influence the evaluative conditioning effect. The potential implications of these findings on repetitive thinking are discussed.
