RESUMEN

The affect misattribution procedure (AMP) is a measure of implicit evaluations, designed to index the automatic retrieval of evaluative knowledge. The AMP effect consists in participants evaluating neutral target stimuli positively when preceded by positive primes and negatively when preceded by negative primes. After multiple prior tests of intentionality, Hughes et al. (Behav Res Methods 55(4):1558-1586, 2023) examined the role of awareness in the AMP and found that AMP effects were larger when participants indicated that their response was influenced by the prime than when they did not. Here we report seven experiments (six preregistered; N = 2350) in which we vary the methodological features of the AMP to better understand this awareness effect. In Experiments 1-4, we establish variability in the magnitude of the awareness effect in response to variations in the AMP procedure. By introducing further modifications to the AMP procedure, Experiments 5-7 suggest an alternative explanation of the awareness effect, namely that awareness can be the outcome, rather than the cause, of evaluative congruency between primes and responses: Awareness effects emerged even when awareness could not have contributed to AMP effects, including when participants judged influence awareness for third parties or primes were presented post hoc. Finally, increasing the evaluative strength of the primes increased participants' tendency to misattribute AMP effects to the influence of target stimuli. Together, the present findings suggest that AMP effects can create awareness effects rather than vice versa and support the AMP's construct validity as a measure of unintentional evaluations of which participants are also potentially unaware.

RESUMEN

Although decades of research have identified facial features relating to people's evaluations of faces, specific features have largely been examined in isolation from each other. Recent work shows that considering the relative importance of these features in face evaluations is important to test theoretical assumptions of impression formation. Here, we examined how two facial features of evolutionary interest, facial attractiveness and facial-width-to-height ratio (FWHR), relate to evaluations of faces across two cultures. Because face evaluations are typically directly measured via self-reports, we also examined whether these features exert differential effects on both direct and indirect face evaluations. Evaluations of standardized photos naturally varying in facial attractiveness and FWHR were collected using the Affect Misattribution Procedure in the United States and Turkey. When their relative contributions were considered in the same model, facial attractiveness, but not FWHR, related to face evaluations across cultures. This positive attractiveness effect was stronger for direct versus indirect evaluations across cultures. These findings highlight the importance of considering the relative contributions of facial features to evaluations across cultures and suggest a culturally invariant role of attractiveness when intentionally evaluating faces.

RESUMEN

The Affect Misattribution Procedure (AMP) is used in many areas of psychological science based on the assumption that it not only taps into attitudes and biases but does so without a person's awareness. Across eight preregistered studies (N = 1603) plus meta-analyses, we reexamined the 'implicitness' of AMP effects, and in particular, the idea that people are unaware of the prime's influence on their evaluations. Results indicated that AMP effects and their predictive validity are primarily moderated by a subset of influence-aware trials (within individuals), and high rates of influence awareness (between individuals). Interestingly, an individual's influence-awareness rate on one AMP predicted how they performed on an earlier AMP, even when the two assessed different attitude domains. Taken together, our results suggest that AMP effects are not implicit in the way that has been claimed, a finding that has implications for the procedure, past findings, and theory.

RESUMEN

Our understanding of implicit bias and how to measure it has yet to be settled. Various debates between cognitive scientists are unresolved. Moreover, the public's understanding of implicit bias tests continues to lag behind cognitive scientists'. These discrepancies pose potential problems. After all, a great deal of implicit bias research has been publicly funded. Further, implicit bias tests continue to feature in discourse about public- and private-sector policies surrounding discrimination, inequality, and even the purpose of science. We aim to do our part by reconstructing some of the recent arguments in ordinary language and then revealing some of the operative norms or values that are often hidden beneath the surface of these arguments. This may help the public learn more about the science of implicit bias. It may also help both laypeople and scientists reflect on the values, interests, and stakeholders involved in establishing, justifying, and communicating scientific research. This article is categorized under: Cognitive Biology > Social Development.

RESUMEN

OBJECTIVE: The purpose of this study was to examine implicit affect toward suicide (i.e., how good/bad suicide is perceived). Some people might be more likely to think about/choose suicide because they perceive it as a good option (to gain relief) relative to available alternatives. METHOD: Implicit affect toward suicide among adults (N = 72) and adolescents (N = 174) with and without suicidal thoughts was examined using first-person (FP) perspective suicide pictures in the affect misattribution procedure (AMP). RESULTS: Suicidal adults' implicit positive affect toward suicide was associated with STB variables, such as explicit valence (r = 0.34) and arousal (r = 0.44) ratings of suicide pictures, and implicit affect differentiated groups above and beyond explicit valence ratings. Contrary to our hypothesis, suicidal participants did not display higher implicit positive affect toward suicide than nonsuicidal participants. However, suicidal participants displayed consistent implicit affect toward different suicide pictures, whereas nonsuicidal participants evaluated some pictures as more pleasant than others (ORs = 1.92-2.27). CONCLUSIONS: Implicit affect toward suicide may relate to STB, but stimuli characteristics (e.g., color) likely influence the accuracy of assessment with the AMP and should be a focus of future research involving this and other implicit measures.

RESUMEN

The current study investigated pre-adolescent children's (N = 140, Mage = 10.11 years, SD = 1.48, 59.5% girls) implicit evaluations of and explicit expectancies about alcohol-related cues as a function of their mothers' drinking behaviors and their exposure to alcohol. Children's implicit evaluative responses were measured using the Affect Misattribution Procedure (AMP), which consisted of trials that depicted pictures of either alcoholic or non-alcoholic beverages, half of which were presented alone (inactive) and half of which were presented with a human interacting with the beverage (active). In addition, children's explicit expectancies, whether they had ever tasted alcohol, and their mothers' alcohol dependency and escape drinking motivations were measured. Results indicated that overall children's implicit evaluations were less positive for alcohol- than for non-alcohol-related cues, and those whose mothers reported higher alcohol dependency evaluated inactive alcohol-related cues more negatively. Moreover, those who had previously tasted alcohol endorsed positive expectancies more than negative expectancies. These findings contribute to our understanding of the processes through which implicit associations are learned in the context of addiction. Understanding cognitive as well as other potential biological and environmental factors that may predict drinking behaviors in youth will aid in the development of more effective evidence-based strategies for the prevention of alcoholism.

RESUMEN

Explicit (directly measured) evaluations are widely assumed to be sensitive to logical structure. However, whether implicit (indirectly measured) evaluations are uniquely sensitive to co-occurrence information or can also reflect logical structure has been a matter of theoretical debate. To test these competing ideas, participants (N = 3928) completed a learning phase consisting of a series of two-step trials. In step 1, one or more conditional statements (A â†’ B) containing novel targets co-occurring with valenced adjectives (e.g., "if you see a blue square, Ibbonif is sincere") were presented. In step 2, a disambiguating stimulus, e.g., blue square (A) or gray blob (¬A) was revealed. Co-occurrence information, disambiguating stimuli, or both were varied between conditions to enable investigating the unique and joint effects of each. Across studies, the combination of conditional statements and disambiguating stimuli licensed different normatively accurate inferences. In Study 1, participants were prompted to use modus ponens (inferring B from A â†’ B and A). In Studies 2-4, the information did not license accurate inferences, but some participants made inferential errors: affirming the consequent (inferring A from A â†’ B and B; Study 2) or denying the antecedent (inferring ¬B from A â†’ B and ¬A; Studies 3A, 3B, and 4). Bayesian modeling using ordinal constraints on condition means yielded consistent evidence for the sensitivity of both explicit (self-report) and implicit (IAT and AMP) evaluations to the (correctly or erroneously) inferred truth value of propositions. Together, these data suggest that implicit evaluations, similar to their explicit counterparts, can reflect logical structure.

RESUMEN

This study examined implicit attitudes towards different eating disorder (ED) relevant stimuli- emaciation, hard-exercise, the self, and eating related stimuli-and their relationship with explicit ED symptoms in two symptomatic samples of college-aged women. Study 1 found that positive implicit attitudes towards eating and self-relevant images were associated with greater state body image satisfaction and self-esteem and with less ED-related intentions. Study 2 found that positive implicit attitudes towards eating and self-relevant images were associated with less trait global ED psychopathology and distress and greater self-esteem. Overall, positive implicit evaluations of eating and self-related stimuli were negatively associated with ED symptoms and related psychopathology and positively related to self-esteem. However, implicit attitudes towards emaciation and hard exercise were not associated with explicit ED symptoms in either sample. These findings suggest that implicit attitudes towards eating and self-related stimuli, in particular, may be viable targets for reconditioning in novel treatment paradigms such as therapeutic evaluative conditioning interventions.

RESUMEN

Voluntary forgetting of unwanted memories is an adaptive cognitive function. However, it remains unknown how voluntary forgetting of unwanted social feedback may influence subsequent memories and evaluations, and what the underlying neurocognitive processes are. Here, we presented participants with peer photos together with feedback indicating social acceptance or rejection, followed by "remember" or "forget" instructive cues, while electroencephalograms were recorded during the experiment. We examined the Directed Forgetting (DF) effect in a recognition memory test, and tested participants' explicit and implicit attitudes toward the peers using a social evaluation task and an affect misattribution procedure (AMP). Both the memory test and the AMP were examined immediately and 3 days after the DF task so to estimate both the instant and the long-term effects of memory control. Behaviorally, immediate memory test showed smaller DF effect for positive than negative social feedback, which suggests that forgetting positive social feedback was more difficult than forgetting negative social feedback. Regarding the ERP results, although participants showed comparable frontal N2 amplitudes (reflecting inhibitory control efforts) following the instruction of forgetting positive and negative social feedback, positive feedback elicited larger late positive potential (LPP) amplitudes than negative feedback during initial encoding phase, suggesting an encoding bias for positive self-relevant information. Intriguingly, voluntary efforts to forget negative social feedback enhanced people's explicit and implicit evaluations toward the feedback senders. These findings provide new evidence for the adaptive function of memory control, which broadens the influence of voluntary forgetting in the context of social interaction and social evaluation.

RESUMEN

In the present study, we measured whether competence-related high and low social status attributed to two unknown individuals affects participants' implicit reactivity to abstract stimuli associated to the identity of the same individuals. During a status-inducing procedure, participants were asked to play an interactive game with two (fake) players coded as high vs low status based on their game competence. Before and after the game, a modified version of the Affective Misattribution Procedure (AMP) was administered in which the players' faces were used as primes. The evaluation target, as is typical to AMP, was a Chinese ideogram. There were two different presentation timings for the prime image: 75 ms and 17 ms. After the status-inducing procedure, the evaluation targets preceded by the high-status prime (i.e. best player's face) were rated as more pleasant than those preceded by the low-status prime (i.e. worst player's face). This effect was only found, however, for the 75 ms lasting prime. Moreover, explicit ratings of the primes showed that the high-status player was rated as more intelligent, competent and dominant than the low status one. These results indicate that implicit preference and explicit evaluation of unacquainted individuals are rapidly modulated by competence-based social status attribution, thus hinting at the plastic nature of social categorization and, relatedly, the malleability of visual preference.

RESUMEN

Feelings and cognitions influence judgment through attribution. For instance, the attribution of positive feelings and cognitions to a stimulus leads to a positive judgment of that stimulus. We examined whether misattribution is moderated by the applicability of a distractor to the judgment question. For instance, when are people more likely to attribute to a target person the affective and cognitive experiences triggered by a kitten - when trying to judge the person's cuteness or trustworthiness? The kitten triggers experiences specifically relevant to cuteness, but people might more easily suspect the kitten's potential influence when judging cuteness rather than trustworthiness. Using the Affect Misattribution Procedure, we found that applicability increases the effect of misattribution on valenced judgments. The results emphasise the importance of specific information (rather than only general valence) in attribution and suggest that high applicability of distractors to the judgment question does not elicit effective correction.

RESUMEN

OBJECTIVE: The current study tested whether people with and without eating disorders (EDs) varied in their implicit attitudes toward ED-relevant stimuli. Additionally, the study tested whether implicit evaluations of ED-relevant stimuli predicted ED symptoms and behaviors over a 4-week interval. METHOD: Participants were people without EDs (N = 85) and people seeking treatment for EDs (N = 92). All participants completed self-report questionnaires and a version of the affect misattribution procedure (AMP) at baseline. The AMP indexed implicit evaluations of average body stimuli, eating stimuli, and ED-symptom stimuli. Participants with EDs completed weekly follow-up measures of ED symptoms and behaviors for 4 weeks. RESULTS: Contrary to predictions, the anorexia nervosa (AN) group did not differ from the no ED group on implicit attitudes toward ED-symptom stimuli, and the bulimia nervosa (BN) group had less positive implicit attitudes toward ED-symptom stimuli relative to the no ED group. In line with predictions, people with AN and BN had more negative implicit attitudes toward average body and eating stimuli relative to the no ED group. In addition, among the ED group more negative implicit attitudes toward eating stimuli predicted ED symptoms and behaviors 4 weeks later, over and above baseline ED symptoms and behaviors. DISCUSSION: Taken together, implicit evaluations of eating stimuli differentiated people with AN and BN from people without EDs and longitudinally predicted ED symptoms and behaviors. Interventions that increase implicit liking of eating-related stimuli may reduce ED behaviors.

RESUMEN

The affect misattribution procedure (AMP) is widely used to measure sensitive attitudes towards classes of stimuli, by estimating the effect that affectively charged prime images have on subsequent judgements of neutral target images. We test its resistance to efforts to conceal one's attitudes, by replicating the standard AMP design while offering small incentives to conceal attitudes towards the prime images. We find that although the average AMP effect remains positive, it decreases significantly in magnitude. Moreover, this reduction in the mean AMP effect under incentives masks large heterogeneity: one subset of individuals continues to experience the 'full' AMP effect, while another reduces their effect to approximately zero. The AMP thus appears to be resistant to efforts to conceal one's attitudes for some individuals but is highly controllable for others. We further find that those individuals with high self-reported effort to avoid the influence of the prime are more often able to eliminate their AMP effect. We conclude by discussing possible mechanisms.

RESUMEN

Implicit measures of racial attitudes often assess reactions to images of individuals to infer attitudes toward an entire social category. However, an increasing amount of research indicates that responses to individuals are highly dependent on context and idiosyncratic features of individual exemplars. Thus, using images of individuals to assess beliefs about a whole social category may not be ideal. Across three time points, we predicted that using images of groups would mitigate the influence of idiosyncratic features of individual targets and, thus, provide a better measurement tool to assess beliefs about a category to which all group members belong. Results revealed that an implicit measure that presented images of Black and White groups had greater construct validity, test-retest reliability, and predictive validity as compared with an implicit measure that presented the same exemplars individually. We conclude that groups provide a window into existing beliefs about social categories.

RESUMEN

Diet failures are often attributed to an increase in cravings for attractive foods. However, accumulating evidence shows that food cravings actually decrease during energy-restricting weight-loss interventions. The current study aimed at elucidating possible mechanisms that may explain how and under which circumstances food cravings in- or decrease during dieting. Specifically, decreases in food cravings during weight-loss diets may be due to effects of energy restriction (homeostatic changes) and to effects of avoiding specific foods (hedonic changes). Thus, we used a selective, hedonic deprivation (i.e., restricting intake of a specific food in the absence of an energy deficit) that precludes homeostatic changes due to energy restriction. Furthermore, interindividual differences in food craving experiences might affect why some individuals are more prone to experience cravings during dieting than others. Thus, we investigated whether a selective deprivation of chocolate would in- or decrease craving and implicit preference for chocolate as a function of trait-level differences in chocolate craving. Participants with high and low trait chocolate craving (HC, LC) refrained from consuming chocolate for 2 weeks but otherwise maintained their usual food intake. Both groups underwent laboratory assessments before and after deprivation, each including explicit (i.e., state chocolate craving) and implicit measures (i.e., Single Category Implicit Association Test, SC-IAT; Affect Misattribution Procedure, AMP). Results showed that hedonic deprivation increased state chocolate craving in HCs only. HCs also showed more positive implicit attitudes toward chocolate than LCs on the SC-IAT and the AMP irrespective of deprivation. Results help to disambiguate previous studies on the effects of dieting on food cravings. Specifically, while previous studies showed that energy-restricting diets appear to decrease food cravings, the current study showed that a selective, hedonic deprivation in the absence of an energy deficit increases food cravings. However, this effect can only be observed for individuals with high trait craving levels. Thus, if attractive foods are strictly avoided through a selective deprivation, HCs are at risk to experience craving bouts in the absence of an energy deficit. As implicit preference was unaffected by chocolate deprivation, strong implicit preference for chocolate likely characterize a stable mechanism that drives consumption in HCs.

RESUMEN

The Affect Misattribution Procedure (AMP) has been forwarded as one of the most promising alternatives to the Implicit Association Test and the evaluative-priming task for measuring attitudes such as prejudice indirectly. We investigated whether the AMP is indeed able to detect an evaluative out-group bias. In contrast to recent conclusions about the robustness of AMP effects, six out of seven pilot studies indicated that participants did not show any prejudice effects in the AMP. Yet, these pilot studies were not fully conclusive with regard to our research question because they investigated different domains of prejudice, used small sample sizes, and employed a modified AMP version. In a preregistered, high-powered AMP study, we therefore examined whether the standard AMP does reveal prejudice against Turks, the biggest minority in Germany, and found a significant, albeit very small prejudice effect. We discuss possible reasons for the AMP's weak sensitivity to evaluations in socially sensitive domains.

RESUMEN

The present study aimed to develop and validate an instrument for measuring implicit attitudes towards speeding, based on the Affect Misattribution Procedure (AMP). The data collected from 140 drivers supported the reliability of the AMP (α=0.80). Results provided some support for the construct validity of the AMP, through its convergence with explicit attitudes towards speeding (r=0.22). Also, the AMP incrementally predicted driving violations (ΔR2=0.034) and traffic accidents (ΔR2=0.022), above and beyond demographic variables and explicit attitudes towards speeding, thus providing initial evidence for its criterion validity. The multiplicative interaction effect between implicit and explicit attitudes (in predicting the same criterion variables) was not supported. Overall, our results provide support for Speeding-AMP's validity and reliability, which can be successfully used in research concerning risky driving behavior.

RESUMEN

The construct validity of the affect misattribution procedure (AMP) has been challenged by theories proposing that the task does not actually measure affect misattribution. The current study tested the validity of the AMP as a measure of affect misattribution by examining three components of the ERP known to be associated with the allocation of motivated attention. Results revealed that ERP amplitudes varied in response to affectively ambiguous targets as a function of the valence of preceding primes. Furthermore, differences in ERP responses to the targets were largely similar to differences in ERPs elicited by the primes. The existence of valence differentiation in both the prime-locked and the target-locked ERPs, along with the similarity in this differentiation, provides evidence that the affective content of the primes is psychologically registered, and that this content influences the processing of the subsequent, evaluatively ambiguous targets, both of which are required if the priming effects found in the AMP are the result of affect misattribution. However, the behavioral priming effect was uncorrelated with ERP amplitudes, leaving some question as to the locus of this effect in the information-processing system. Findings are discussed in light of the strengths and weaknesses of using ERPs to understand the priming effects in the AMP.

RESUMEN

BACKGROUND AND OBJECTIVES: Previous studies using modified versions of the Affect Misattribution Procedure (AMP; Payne, Cheng, Govorun, & Stewart, 2005) have revealed that there is an implicit negative evaluation bias of illness-related information in patients with hypochondriasis (HYP), which might be a maintaining feature of HYP. However, there is no evidence on whether this bias might be targeted successfully by effective treatments, such as exposure therapy (ET) or cognitive therapy (CT). This is the first study to examine the change in negative implicit evaluations in a randomized controlled trial, including individual CT and ET, compared to a wait-list control group for HYP. METHODS: An AMP with illness, symptom and neutral primes was used in 70 patients with HYP before and after treatment (wait-list respectively). RESULTS: There was no significant change in negative implicit affective evaluations in both CT and ET, compared to wait-list. However, comparisons between the two active treatments revealed an interaction effect, that only for CT were the affective reactions on illness-as well as symptom-related prime trials (but not neutral primes) significantly more positive at post-compared to pre-treatment. In CT but not in ET, the reduction of implicit negative evaluation bias regarding symptom-related primes was significantly related to the reduction of self-reported health anxiety. LIMITATIONS: The small subsample sizes for CT and ET, in comparison to wait-list, prohibit the detection of smaller effects. CONCLUSIONS: Formal cognitive restructuring is necessary for reducing implicit negative evaluation bias in HYP, but the latter is not a prerequisite for reducing health anxiety. Thus, the importance of the negative implicit evaluation bias for the maintenance of HYP remains questionable.

RESUMEN

In two experiments, the impact of faking on the affect misattribution procedure (AMP) was examined. Results revealed that faking influences both the overall means and the convergent validity of AMP effects in terms of correlations with self-report measures. Faking effects were very selective in that they affected fake-prime trials only, for which AMP effects were significant, but reversed in direction, while AMP effects for non-fake trials remained intact. Importantly, neither strategic advice nor prior task experience was a necessary prerequisite for successful faking. The discussion focuses on possible processes underlying successful faking in the AMP.
