RESUMO

Many researchers have tackled the question of how behavior is influenced by its outcomes. Some have adopted a nonmechanistic (functional) perspective that attempts to describe the influence of outcomes on behavior. Others have adopted a mechanistic (cognitive) perspective that attempts to explain the influence of outcomes on behavior. Orthogonal to this distinction, some have focused on the influence of outcomes that a behavior had in the past, whereas others also consider the influence of outcomes that a behavior might have in the future. In this article, we relate these different perspectives with the goal of reducing misunderstandings and fostering collaborations between researchers who adopt different perspectives on the common question of how behavior is influenced by its outcomes.

RESUMO

We applaud De Neys for drawing attention to the interaction between intuiting and deliberating without committing to single- or dual process models. It remains unclear, however, how he conceptualizes the distinction between intuiting and deliberating. We propose several levels at which the distinction can be made and discuss the merits of defining intuiting and deliberating as different types of behavior.

RESUMO

Pairing a cue (e.g., an image of a geometrical figure) with an outcome (e.g., an image with aversive content) can result in the cue eliciting thoughts of that outcome (i.e., thought conditioning). Previous research suggests an advantage of counterconditioning over extinction in reducing thoughts of (aversive) outcomes. However, it is unclear how robust this effect is. This study aimed to (1) replicate the previously observed advantage of counterconditioning over extinction and (2) test whether counterconditioning leads to less reinstatement of thoughts of an aversive outcome relative to extinction. Participants (N = 118) underwent a differential conditioning procedure and were then assigned to one of three conditions: extinction (i.e., the aversive outcome was no longer presented), no extinction (i.e., the aversive outcome continued to be presented) and counterconditioning (i.e., the aversive outcome was replaced with positive images). After three unsignaled outcome presentations, participants indicated in a return of fear test the extent to which they thought of the aversive outcome. As predicted, counterconditioning was more successful in reducing thinking of the aversive outcome than extinction. Yet, there were no differences in return of thoughts of the aversive outcome between the two conditions. Future research should consider other return of fear procedures.

RESUMO

BACKGROUND AND OBJECTIVES: Models are omnipresent in science. We introduce a novel framework to achieve more effective modelling practices in general psychology and experimental psychopathology. METHOD: We analyze three types of models that are common in psychology: laboratory models, computational models, and cognitive models. We then evaluate two common ways to assess the translational value of models (phenomenological similarity and deep similarity) as well as an arguably underappreciated way (functional similarity). Functional similarity is based on an assessment of whether variables (e.g., the administration of a pharmacological substance) have a similar effect (a) in the model (e.g., in a fear conditioning procedure) and (b) on the real-life target phenomenon (e.g., on real-life anxiety complaints). CONCLUSIONS: We argue that the assessment of functional similarity is a powerful tool to assess the translational value of models in the field of experimental psychopathology and beyond.

RESUMO

We explore the idea that some learning phenomena can be thought of as instances of relational behavior-more specifically, arbitrarily applicable relational responding (AARR). After explaining the nature of AARR, we discuss what it means to say that learning phenomena such as evaluative and fear conditioning are instances of AARR. We then list several implications of this perspective for empirical and theoretical research on learning, as well as for how learning phenomena relate to other psychological phenomena in human and nonhuman animals.

RESUMO

People are more likely to engage in various suboptimal behaviors such as overeating, addictive behaviors, and short-sighted financial decision-making when they are under stress. Traditional dual-process models propose that stress can impair the ability to engage in goal-directed behavior so that people have to rely on habitual behavior. Support for this idea comes from a study by Schwabe and Wolf (2010), in which stressed participants continued to perform a learned instrumental behavior leading to a liquid after the liquid was devalued with a satiation procedure. Based on these findings, suboptimal behavior under stress is often seen as habitual. In the present study, we conducted a conceptual replication of the study by Schwabe and Wolf (2010). Instead of using a satiation procedure to achieve the outcome devaluation, we devalued outcomes through taste aversion. We did not replicate the pattern of findings by Schwabe and Wolf (2010). Our results indicate instead that stressed participants were sensitive to outcome values when the outcomes became truly aversive and hence that their behavior was goal-directed. This suggests either that (a) habitual processes are subject to boundary conditions or (b) the processes responsible for the findings of Schwabe and Wolf (2010) were never habitual to begin with. This may have far-reaching implications for explaining suboptimal behavior under stress in general. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMO

People often keep engaging in behaviors that used to be successful in the past but which are knowingly no longer effective in the current situation, so-called "action slips." Such action slips are often explained with stimulus-driven processes in which behavior is caused by a stimulus-response association and without information about the outcome of the behavior. This process is contrasted with a goal-directed process in which behavior is selected because it is expected to lead to a desired outcome. Failing to act in line with changes in the outcome is taken as evidence for stimulus-driven processes. Stimulus-driven processes are assumed to get installed after overtraining and to be deployed under poor operating conditions. In line with this, previous research has found that action slips are more likely to occur after extensive training and when under time pressure. We propose an alternative goal-directed explanation according to which action slips are caused by a goal-directed process that relies on old, no longer accurate, outcome information. In the current study, participants learned four stimulus-response-outcome contingencies during a single (i.e., moderate training) or a 4-day training schedule (i.e., extensive training). Afterward, two contingencies were reversed and performance was assessed under time pressure. Results show that after extensive training, participants not only committed more action slips but also reported more old response-outcome contingencies in line with these action slips. This is consistent with the goal-directed explanation that action slips result from a reliance on old, no longer accurate outcome information.

RESUMO

Wood et al. (2022) reviewed arguments in support of the idea that much of human behavior is habitual. In this commentary, we first point at ambiguities in the way Wood et al. referred to habits. This allows us to clarify the question that lies at the core of the debate on habits: To what extent is habitual behavior mediated by stimulus-response associations or by goal representations? We then argue that Wood et al. dismissed goal-directed explanations of habitual behavior too easily. Finally, we point out that Wood et al.'s reanalysis of our data is misleading in that a more fine-grained analysis supports rather than questions goal-directed accounts.

RESUMO

We develop a new perspective on various forms of psychological suffering - including attachment issues, burn-out, and fatigue complaints - by drawing on the construct of learned helplessness. We conceptualise learned helplessness in operant terms as the behavioural effects of a lack of reinforcement and in goal-directed terms as the dysregulation of goal-directed behaviour. Our central claim is that if one fails to reach a goal (e.g. the goal to secure a job), then not only this goal but also other related goals (e.g. the goal to maintain social relationships) may lose their motivating effects. The similarity relation between goal stimuli can therefore shed light on how failure in one life domain can come to affect various other life domains. We detail the relation between our proposal and existing theories and discuss new research and clinical directions.

RESUMO

Effective behavioral interventions are essential to address urgent societal challenges. Over the past decade, nudging interventions (i.e., arranging the environment to promote adaptive behavioral choices) have surged in popularity. Importantly, effective application of the nudging approach requires clear guiding principles with a firm basis in behavioral science. We present a framework for nudging interventions that builds on evidence about the goal-directed inferential processes underlying behavior (i.e., processes that involve context-dependent inferences about goals and the actions available to achieve these goals). We used this framework to develop nudging interventions that target context-relevant cognitive inferences. We examined the effectiveness of these inference nudging interventions for promoting two important types of societal behavior: pro-environmental actions and adherence to COVID-19 guidelines. As predicted, two online studies revealed that inference nudging interventions successfully increased energy conservation (Study 1) as well as social distancing during the COVID-19 crisis (Study 2). A field experiment found that inference nudging interventions increased hand disinfection in a real-life store during the COVID-19 crisis (Study 3). Our findings highlight the importance of applying state-of-the-art insights about the (inferential) determinants of behavior in behavior change interventions.

RESUMO

Background: Learning tasks have been used to predict why some, and not others, develop posttraumatic stress disorder (PTSD) after exposure to a traumatic event. There is some evidence from prospective studies in high risk profession samples that reduced extinction learning might represent a marker or even a vulnerability factor for PTSD development. Objective: Since the evidence is scarce, the aim of this study was to perform a conceptual replication of an earlier prospective study, testing whether pretrauma extinction learning predicts later PTSD symptom severity. Method: A sample of 529 fire fighters performed a conditioning task at baseline and filled out questionnaires to assess PTSD symptom severity and neuroticism. At six and 12 months follow-up, exposure to stressful events and PTSD symptom severity were measured. Results: Results indicate that previous findings were not replicated: although reduced extinction learning was associated with higher PTSD symptom severity at baseline, extinction learning did not predict PTSD symptom severity at follow-up. Only PTSD symptom severity at baseline and stressor severity predicted PTSD symptom severity at follow-up. Conclusions: Since earlier findings on the predictive value of pre-trauma extinction learning on PTSD symptom severity were not replicated, extinction learning might not be a general risk factor PTSD for all individuals. More prospective studies including multiple factors seem needed to unravel the complex relationships of these factors influencing PTSD development. HIGHLIGHTS: Reduced extinction learning correlated with higher PTSD symptom severity at baseline.Reduced extinction learning did not predict PTSD symptom severity at follow-up.The predictive effect of pre-trauma extinction learning on PTSD was not replicated.


Antecedentes: Las tareas del aprendizaje se han utilizado para predecir por qué algunos, y no otros, desarrollan trastorno de estrés postraumático (TEPT) después de la exposición a un evento traumático. Existe cierta evidencia de estudios prospectivos en muestras de profesiones de alto riesgo de que el aprendizaje de extinción diminuido podría representar un marcador o incluso un factor de vulnerabilidad para el desarrollo del TEPT. Objetivo: Dado que la evidencia es escasa, el objetivo de este estudio fue realizar una replicación conceptual de un estudio prospectivo anterior, probando si el aprendizaje de extinción pretraumático predice la gravedad posterior de los síntomas de TEPT. Método: Una muestra de 529 bomberos realizó una tarea de condicionamiento al inicio del estudio y llenó cuestionarios para evaluar la gravedad de los síntomas del TEPT y neuroticismo. A los 6 y 12 meses de seguimiento, se midió la exposición a eventos estresantes y la gravedad de los síntomas de TEPT. Resultados: Los resultados indican que los hallazgos anteriores no se replicaron. Aunque el aprendizaje de extinción disminuido se asoció con una mayor gravedad de los síntomas de TEPT al inicio del estudio, el aprendizaje de extinción no predijo la gravedad de los síntomas de TEPT en el seguimiento. Solo la gravedad de los síntomas de TEPT al inicio y la gravedad del factor estresante predijeron la gravedad de los síntomas de TEPT en el seguimiento. Conclusiones: Dado que los hallazgos anteriores sobre el valor predictivo del aprendizaje de extinción pretraumático sobre la gravedad de los síntomas de TEPT no se replicaron, el aprendizaje de extinción podría no ser un factor de riesgo general de TEPT para todos los individuos. Parece que se necesitan más estudios prospectivos que incluyan múltiples factores para desentrañar las complejas relaciones de estos factores que influyen en el desarrollo del TEPT.

RESUMO

To date, the phenomenological and functional aspects of autobiographical memory have by and large been studied separately. This is quite remarkable, given that both can inform each other, and that investigating their interaction can add to the understanding of the (in)adaptivity of certain memory characteristics for our well-being. In other words, examining how particular features of autobiographical memory are adept or inept at serving specific functions, could help us to better comprehend and explain relations between memory and psychological well-being. We discuss previous attempts to integrate phenomenology with functionality and formulate three main directions for future research based on the current state of the art. The directions concern (1) focusing on functionality (adaptivity) and not merely on the use of memories in phenomenological work, (2) attention for the bidirectionality of the relation between phenomenology and functionality, and (3) the addition of narrative constructs like coherence to the traditional range of phenomenological features. We will illustrate our directions for the reintegration of phenomenology with functionality through the social function of coherent autobiographical memories. This framework could help to stimulate future empirical studies and pave the road for new clinical interventions to improve psychological well-being.

RESUMO

Little is known about why people behave the way they do in threatening situations. Some theories invoke a transfer of responses from unconditioned stimuli (US) to conditioned stimuli (CS), but this principle goes astray because responses to the US and CS can differ substantially. The idea that we introduce here is that the pattern of responses to a newly established CS does not come from the US but (at least partly) transfers from how one (learned to) respond(s) to previously encountered stimuli with threat value. So, we conceptualize threat value as a stimulus feature that allows responses to transfer between stimuli that share this feature (in the same way as, for example, overlap in color or shape can support transfer). In contrast to prevailing views, this new perspective focuses on the relation between the CS and already established threat signals rather than on the relation between the CS and the US. We discuss how this shared features perspective on human fear responding can inspire future directions in both the laboratory and clinical practice.

RESUMO

A common assumption in human fear conditioning research is that findings are informative for the etiology and treatment of clinical anxiety. One way to empirically evaluate the external validity of fear conditioning is by prospective studies. We review available prospective research investigating whether individual performance in fear conditioning predicts individual differences in anxiety levels and exposure-based treatment outcome. We focus on fear extinction, generalization, acquisition, and avoidance. Results suggest that reduced extinction and broader generalization predict higher anxiety levels. Results with respect to the predictive value of acquisition for anxiety levels are mixed. With regard to predicting exposure-based treatment outcome, some studies do find an association with extinction whereas others do not. The majority of studies does not find an association with acquisition. Evidence on extinction recall is limited and not consistent. The interpretation of these results requires caution. The number of available studies is limited. It is possible that not all work, in particular studies with only null effects, has found its way to publication. Future research on this topic will benefit from large sample sizes, preregistered hypotheses, full transparency about the conducted analyses and the publication of high-quality studies with null effects.

RESUMO

Individual differences in extinction learning have attracted ample attention of researchers and are under investigation as a marker for the onset of anxiety disorders and treatment response. Unfortunately, the common paradigm for obtaining the extinction rate, which entails aversive stimulus pairings, is subject to practical limitations. Therefore, the present study assessed whether the use of an aversive stimulus is actually needed to get a good estimate of the extinction rate. A total of 161 undergraduate students completed a conditioning task with both an aversive and a non-aversive stimulus. Using latent class growth analysis (LCGA), distinct trajectories, representing normal and stunted extinction learning, were identified for both these stimulus types. Participants' membership in these classes largely overlapped for aversive and non-aversive stimulus pairings and respective extinction indices were significantly correlated. Thereby, findings suggest that the use of a non-aversive stimulus could suffice for successfully capturing individual differences in extinction learning. However, future studies are needed to confirm that conditioning with a non-aversive stimulus may serve to predict clinically relevant outcomes.

RESUMO

Memory is under investigation as one of the core mechanisms of psychopathology. The traditional cognitive view of memory as a stable structure with a range of set characteristics can be complemented with a perspective that considers remembering as a behaviour that varies fluidly across contexts. Remembering may serve adaptation to the environment by fulfilling a directive function, a self-function and a social function. A failure to fulfil these functions may be a risk factor for psychopathology. Implications of the discussed functionalist perspective include the importance of reinforcing adaptive ways of remembering during early development, the possibility of treating maladaptive ways of remembering through contextual interventions and the added ecological validity of using ambulatory assessment methods.

RESUMO

As an alternative to biological reductionist and network approaches to psychopathology, we propose a nonreductionist mental-mechanistic approach. To illustrate this approach, we work out the implications of the goal-directed framework of Moors et al., which has the potential to explain the heterogeneous manifestations of psychopathology with a restricted set of broad theoretical principles.

RESUMO

Current theories propose that our sense of curiosity is determined by the learning progress or information gain that our cognitive system expects to make. However, few studies have explicitly tried to quantify subjective information gain and link it to measures of curiosity. Here, we asked people to report their curiosity about the intrinsically engaging perceptual 'puzzles' known as Mooney images, and to report on the strength of their aha experience upon revealing the solution image (curiosity relief). We also asked our participants (279) to make a guess concerning the solution of the image, and used the distribution of these guesses to compute the crowdsourced semantic entropy (or ambiguity) of the images, as a measure of the potential for information gain. Our results confirm that curiosity and, even more so, aha experience is substantially associated with this semantic information gain measure. These findings support the expected information gain theory of curiosity and suggest that the aha experience or intrinsic reward is driven by the actual information gain. In an unannounced memory part, we also established that the often reported influence of curiosity on memory is fully mediated by the aha experience or curiosity relief. We discuss the implications of our results for the burgeoning fields of curiosity and psychoaesthetics.

RESUMO

BACKGROUND AND OBJECTIVES: Fatigue is an adaptive state after prolonged effort and often goes hand in hand with changes in behavior and motivation, such as the urge to stop exerting further effort. However, fatigue may become chronic in nature, as seen in multiple psychiatric disorders and chronic diseases, thereby losing its adaptive function. The etiology of fatigue symptoms remains poorly understood. We aimed to investigate whether nocebo information about the fatigue inducing nature of a cognitive task may contribute to the experience of fatigue and the motivational urge to stop. METHODS: Participants (N = 46) repeatedly rated currently experienced fatigue while engaging in cognitive effort (working memory task). Crucially, half of participants received nocebo instructions prior to this task, whereas the other half only received neutral information. RESULTS: Over the entire sample, results showed an increase in fatigue and urge to stop as the task progressed. Crucially, participants in the nocebo condition reported a higher urge to stop throughout the task relative to participants in the neutral condition. No significant effects were found for fatigue. Interestingly however, after controlling for baseline differences between conditions in negative affect, there was a significant Condition*Task block interaction effect on fatigue. LIMITATIONS: Limitations include the relatively short experimental protocol and the underrepresentation of male relative to female participants. CONCLUSIONS: These findings suggest that heightened awareness among clinicians and therapists about potential nocebo effects in their communication is warranted.
