Self-affirmation may be an effective tool to reduce prejudice and discrimination against minority groups. Its hypothesised mechanism is that prejudice is a defensive act that can be reduced by reinforcing a positive imagine of the self. Such a reinforced self-image is meant to weaken perceived threat to one’s social identity that may be posed by minority groups, such as Muslims in majority Christian countries.

 

To address mixed evidence for the effectiveness of self-affirmation across the literature, this Registered Report (RR) was designed to elucidate conditions under which self-affirmation may reduce prejudice and discrimination. Whether self-affirmation has the desired effect may be moderated by an individual’s internal representation of secularism. That is, as a reaction to self-affirmation, people may flexibly endorse their feelings towards secularism (‘ideological malleability’) to either reduce prejudice, or maintain and justify it. This study is the first to consider whether this effect depends on a participant’s attitude that French citizens should be able to practice their religion in public places (‘historical’ secularism), or that they should hide it in public (‘new’ secularism).

 

Alnajjar et al. present a study design (i.e., three-way mixed ANOVA) in which they self-affirmed French participants (N=602) with differing internal representations of secularism. Study results demonstrated that a historical representation of secularism is associated with less effective and behavioural prejudice towards religious groups compared to a new representation of secularism. Participants’ prejudiced attitudes were larger against Muslims than against Christians. It was unexpected that new secularism was linked to negative attitudes towards religious minority groups given that the French government mandated by law that religion should not be practiced in public. Across three self-affirmation conditions (i.e., self-affirmation on a threat-related value, a threat-unrelated value, and no self-affirmation), the authors found no evidence that self-affirmation affected prejudice against religious groups, and there was no evidence that the effectiveness of self-affirmation depended on a participants representation of secularism, which contradicted their pre-registered hypotheses. This paper adds conclusive and sufficiently-powered results to a body of literature with mixed evidence for the effectiveness of self-affirmation.

 

It increased the robustness of this study that the design considered desirability concerns and employed multiple manipulation checks. By considering nuances of public opinion towards secularism in France specifically, the authors identified a unique opportunity to investigate ideological malleability, which can be challenging to conceive and directly measure.

Self-control has shown to be a trait related to beneficial outcomes, including health, academic achievement and relationship quality. It is mostly understood as the ability to surpress immediate urges in order to achieve long-term goals, such as not watching another episode and therefore reaching a healthy amount of sleep. An emerging perspective on self-control shows that there is broader variety in applied strategies, such as removing oneself from a tempting situation, or reminding oneself of one's long-term goal, or reinterpreting the temptation.

 

Katzir et al. (2021) developed a novel instrument, the Self-Control Strategy Scale, that measured the tendency to engage in eight such strategies. In the current study, Roth et al. (2023) propose to translate the scale into German and assess its psychometric properties. Further, they will determine which strategies are related to particular outcomes that may be beneficial; for example, amount of physical activity engaged in, how healthy the diet is, exam performance and life satisfaction.

 

The Stage 1 manuscript was evaluated over two rounds of in-depth review by the recommender and at least two expert reviewers, before issuing in-principle acceptance.

Surveys that measure self-report are a workhorse in psychology and the social sciences, providing a vital window into beliefs, attitudes and emotions, both at the level of groups and individuals. The validity of self-report data, however, is an enduring methodological concern, with self-reports vulnerable to a range of response biases, including (among others) the risk of social desirability bias in which, rather than responding honestly, participants answer questions in a way that they believe will be viewed favourably by others. One proposed solution to socially desirable responding is the so-called Bayesian Truth Serum (BTS), which aims to incentivise truthfulness by taking into account the relationship between an individual’s response and their belief about the dominant (or most likely) response given by other people, and then assigning a high truthfulness score to answers that are surprisingly common.

 

Although valid in theory (under a variety of assumptions), questions remain regarding the empirical utility of the BTS. One area of concern is participants’ uncertainty regarding incentives for truth-telling – if participants don’t understand the extent to which telling the truth is in their own interests (or they don’t believe that it matters) then the validity of the BTS is undermined. In the current study, Neville and Williams (2024) aim to test the role of clarifying incentives, particularly for addressing social desirability bias when answering sensitive questions. The authors will administer an experimental survey design including sensitive questions, curated from validated scales, that are relevant to current social attitudes and sensitivities (e.g. “Men are not particularly discriminated against”, “Younger people are usually more productive than older people at their jobs”). Three groups of participants will complete the survey under different incentive conditions: the BTS delivered alone in standard format, the BTS with an interim bonus payment that is awarded to participants (based on their BTS score) half-way through the survey to increase certainty in incentives, and a Regular Incentive control group in which participants receive payment without additional incentives.

 

The authors will then address two questions: whether the BTS overall effectively incentivises honesty (the contrast of BTS alone + BTS with interim payment vs the Regular Incentive group), and whether interim payments, specifically, further boost assumed honesty (the contrast of BTS alone vs BTS with interim payment). Regardless of how the results turn out, the study promises to shed light on the effectiveness of the BTS and its dependence on the visibility of incentives, with implications for survey design in psychology and beyond.

Words have served as stimuli in memory experiments for over a century. What makes some words stand out in memory compared to others? One plausible answer is that semantically rich words are more distinctive and therefore exhibit a mirror effect in recognition memory experiments where they are likely to be correctly endorsed and also less likely to be confused with other words (Glanzer & Adams, 1985). Semantic richness can arise due to extensive prior experience with the word in multiple contexts but can also arise due to sensorimotor grounding, i.e., direct perceptual and action-based experience with the concepts represented by the words (e.g. pillow, cuddle). However, previous experiments have revealed inconsistent recognition memory performance patterns for words based on different types of sensorimotor grounding (Dymarska et al., 2023). Most surprisingly, body-related words such as cuddle and fitness exhibited greater false alarm rates. 

In the current study, Dymarska and Connell (2023) propose to test two competing theories that can explain the increased confusability of body-related words: 1) the adaptive account - contextual elaboration-based strategies activate other concepts related to body and survival, increasing confusability; and 2) the attentional account - somatic attentional mechanisms automatically induce similar tactile and interoceptive experiences upon seeing body-related words leading to less distinctive memory traces. The adaptive account leads to different predictions under intentional and incidental memory conditions. Specifically, contextual elaboration strategies are unlikely to be employed when participants do not expect a memory test and therefore in an incidental memory task, body-related words should not lead to inflated false alarm rates (see Hintzman (2011) for a discussion on incidental memory tasks and the importance of how material is processed during memory tasks). However, the attentional account is not dependent on the task instructions or the knowledge about an upcoming memory test. 

Here, Dymarska and Connell (2023) have designed an incidental recognition memory experiment with over 5000 words, disguised as a lexical decision task using carefully matched pseudowords during the encoding phase. The sample size will be determined by using a sequential hypothesis testing plan with Bayes Factors. To test the predictions of the adaptive and attentional accounts, the authors derive a set of lexical and sensorimotor variables (including a body-component) after dimensionality reduction of a comprehensive set of lexical and semantic word features. The analysis will involve running both Bayesian and frequentist hierarchical linear regression to explain four different measures of recognition memory performance based on the key sensorimotor variables and other baseline/confounding variables. While this analysis plan enables a comparison with the earlier results from an expected memory test (Dymarska et al., 2023), the current study is self-contained in that it is possible to distinguish the adaptive and attentional accounts based on the effect of body component scores on hit rate and false alarm rate.

The study plan was refined across two rounds of review, with input from two external reviewers after which the recommender judged that the study satisfied the Stage 1 criteria for in-principle acceptance (IPA).

For nearly a century, rhythmic patterns in electrical brain activity have been of major interest in neuroscience and electrophysiology, but much remains to be discovered about their causal contribution to cognition and behaviour. Low-frequency oscillations in the alpha band (~8-13 Hz) have been suggested to facilitate the organisation and delivery of visual information to higher-level systems, including those involved in perception and decision-making. If so, visual perception should also operate in cycles that are synchronous with – and determined by – the phase of ongoing low-frequency oscillatory activity.

 

In this #EEGManyLabs study, Ruzzoli et al. (2023) propose a large-scale, multi-lab investigation (9 labs; N=315 human participants) of the relationship between the phase of alpha oscillations and visual perception. The authors focus in particular on replicating a formative study by Mathewson et al. (2009) which reported that during high-amplitude alpha fluctuations, stimulus visibility depended on the time the stimulus was presented relative to the phase of the pre-stimulus alpha activity. In addition, the amplitude of visual evoked potentials recorded with EEG was larger when the target was presented at peaks in pre-stimulus alpha. To explain their findings, Mathewson proposed an influential pulsed inhibition hypothesis in which low alpha power boosts both cortical excitability and stimulus processing (and hence perception), while high alpha power makes stimulus processing dependent on the phase during the alpha cycle at which the stimulus is presented.

 

In the first of (up to) two studies, the authors will seek to directly replicate the key finding of Mathewson et al: that when alpha power is high, the oscillatory phase determines perceptual performance and event-related electrophysiological correlates in a masked visual detection task. Specifically, (a) alpha oscillations are predicted to modulate the probability of perceiving a target stimulus within a single oscillatory cycle, with detection rate associated with separated (and potentially opposite) phase angles, and (b) alpha phase at the onset of the stimulus should drive electrophysiological correlates of stimulus processing (including the amplitude and/or latency of the N1 ERP component).

 

Provided the results of this first study do not conclusively disconfirm these hypotheses, the authors will then conduct a follow-up study in which the temporal predictability of the target onset (in relation to a fixation stimulus) is reduced to test the more severe hypothesis that the observed correlations between alpha phase and perception are linked directly to ongoing oscillations, independent of temporal expectations.
