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.

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.

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 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.

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.

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.

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.

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.

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.

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.

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.

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.

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 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.

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.

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.

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).

Article Synopsis
  • Recent research shows that instructions regarding the relationship between a conditioned stimulus (CS) and an unconditioned stimulus (US) can significantly influence human fear conditioning.
  • In a study with 102 participants, three groups were instructed differently about CS-US contingencies: one group received clear instructions, another group was encouraged to discover the relationship, and the third group received no instructions at all.
  • Results indicated that the first two groups exhibited stronger fear responses and better contingency awareness than the third group, suggesting the need for more transparency about instructions in fear conditioning studies.

This special issue celebrates the 100th anniversary of the Little Albert study, published in February 1920, which marked the birth of human fear conditioning research. The collection of papers in this special issue provides a snapshot of the thriving state of this field today. In this Editorial, we first trace the historical roots of the field and then provide a conceptual analysis of the many ways in which human fear conditioning is currently used in theory and treatment development, with special reference to the contributions in this special issue.

The generalization of learned behavior has been extensively investigated, but accounting for variance in generalized responding remains a challenge. Based on recent advances, we demonstrate that the inclusion of perceptual measures in generalization research may lead to a better understanding of both intra- and interindividual differences in generalization. We explore various ways through which perceptual variability can influence generalized responding.

For decades already, the human fear conditioning paradigm has been used to study and develop treatments for anxiety disorders. This research is guided by theoretical assumptions that, in some cases indirectly, stem from the tradition of association formation models (e.g.
