Using pavlovian higher-order conditioning paradigms to investigate the neural substrates of emotional learning and memory

In first-order Pavlovian conditioning, learning is acquired by pairing a conditioned stimulus (CS) with an intrinsically motivating unconditioned stimulus (US; e.g., food or shock). In higher-order Pavlovian conditioning (sensory preconditioning and second-order conditioning), the CS is paired with a stimulus that has motivational value that is acquired rather than intrinsic. This review describes some of the ways higher-order conditioning paradigms can be used to elucidate substrates of learning and memory, primarily focusing on fear conditioning. First-order conditioning, second-order conditioning, and sensory preconditioning allow for the controlled demonstration of three distinct forms of memory, the neural substrates of which can thus be analyzed. Higher-order conditioning phenomena allow one to distinguish more precisely between processes involved in transmission of sensory or motor information and processes involved in the plasticity underlying learning. Finally, higher-order conditioning paradigms may also allow one to distinguish between processes involved in behavioral expression of memory retrieval versus processes involved in memory retrieval itself.     

‘So Help Me God’? Does oath swearing in courtroom scenarios impact trial outcomes?

In countries such as Britain and the US, court witnesses must declare they will provide truthful evidence and are often compelled to publicly choose between religious (“oath”) and secular (“affirmation”) versions of this declaration. Might defendants who opt to swear an oath enjoy more favourable outcomes than those who choose to affirm? Two preliminary, pre-registered survey studies using minimal vignettes (Study 1, N = 443; Study 2, N = 913) indicated that people associate choice of the oath with credible testimony; and that participants, especially religious participants, discriminate against defendants who affirm. In a third, Registered Report study (Study 3, N = 1821), we used a more elaborate audiovisual mock trial paradigm to better estimate the real-world influence of declaration choice. Participants were asked to render a verdict for a defendant who either swore or affirmed, and were themselves required to swear or affirm that they would try the defendant in good faith. Overall, the defendant was not considered guiltier when affirming rather than swearing, nor did mock-juror belief in God moderate this effect. However, jurors who themselves swore an oath did discriminate against the affirming defendant. Exploratory analyses suggest this effect may be driven by authoritarianism, perhaps because high-authoritarian jurors consider the oath the traditional (and therefore correct) declaration to choose. We discuss the real-world implications of these findings and conclude the religious oath is an antiquated legal ritual that needs reform.     

Controlling the Past to Control the Future: Christian Nationalism and Mandatory Patriotic Education in Public Schools

Recent debates about whether educators should teach America's racist history have sparked activism and legislation to ensure students are taught American history in such a way that promotes “patriotism,” amplifying cherished national myths, emphasizing American exceptionalism, and erasing negative historical facts. Building on insights from both social dominance theory and Christian nationalism research, we propose Christian nationalism combines legitimizing myths that whitewash America's past with authoritarian impulses and thus seeks to enforce “patriotic” content in public school classrooms. We also theorize this connection varies across racial, partisan, and ideological identities. Data from a nationally-representative survey of Americans affirm Christian nationalism is by far the leading predictor Americans believe “We should require public school teachers to teach history in a way that promotes patriotism.” This association is consistent across race (possibly due to divergent meanings of both “Christian nationalism” and “patriotism” across groups), but varies by partisanship and ideological identity for whites. Specifically, Christian nationalism brings whites who identify with the ideological and political left into complete alignment with their conservative counterparts who are already more likely to support mandatory patriotic education. Our findings provide critical context for ongoing battles over public-school curricula and education's role in perpetuating social privilege.     

Emotional,motivational and attitudinal consequences of autonomous prosocial behaviour

When do prosocial actors experience positive versus negative psychological outcomes from helping others? In four studies and an internal meta-analysis, we tested the hypothesis that autonomy shapes the psychological consequences of helping others. In Study 1, prosocial behaviour was associated with a robust pattern of negative well-being outcomes (i.e., depression, anxiety, stress) for individuals low but not high in autonomy. In Studies 2–4, relative to reflecting on a neutral interpersonal experience, reflecting on an autonomous helping experience increased sadness and happiness, strengthened intentions to help in the future and raised support for social welfare. By contrast, reflecting on a controlled helping experience increased negative emotions and decreased positive emotions, but did not affect attitudes or behavioural intentions. Collectively, the findings indicate that autonomy (or lack thereof) shapes the emotional, motivational and attitudinal consequences of helping behaviour.     

‘When my mummy and daddy aren't looking at me when I do my maths she helps me’; Children can be taught to create imaginary companions: An exploratory study

Spontaneous imaginary companion (SIC) creation in childhood is a typical imaginative play behaviour associated with advanced sociocognitive skills; however, the direction of causality has not been established. To investigate this experimentally, researchers must determine whether children can create, on request, qualitatively equivalent imaginary companions (ICs) to those created spontaneously. We examined whether children could create ICs, and how these compared to SICs. Nine elementary school children were encouraged to create ICs in a 3-month intervention. Accounts of elicited ICs were compared with an age-matched sample of interviewees with SICs. Seven children maintained ICs for 6 months post intervention. Template analysis of IC interviews found four themes: Realistic Play, Multifaceted IC Mind, Utility of the IC, and Elicited IC Across Time. Analysis suggests elicited and SICs were similar in nature and utility, although intervention ICs tended to have animal rather than human appearances. Findings support the argument that children can be encouraged to create ICs similar to SICs.     

Emotional reactions to dramatic film stimuli: the influence of cognitive and emotional empathy

The idea that empathy may best be considered a multidimensional construct, consisting of both cognitive and emotional facets, has recently been gaining in popularity. To date, however, little research explicitly based on such a view has been carried out. We conducted the present experiment to explore the different influences of cognitive and emotional empathy on two types of responses to dramatic stimuli: positive and negative emotional reactions. Consistent with a multidimensional view of empathy, the two types of empathy exhibited different effects; positive emotional reactions were affected primarily by cognitive empathy, and negative emotional reactions were most heavily influenced by emotional empathy. The results are discussed in terms of their relevance to a multidimensional approach to the study of empathic responding.     

Repression and the inaccessibility of affective memories

The fundamental assumption that repression involves an inaccessibility to affective memories has not been directly addressed in empirical research. In the present study we examined three groups of subjects (repressors, low anxious, and high anxious) under six conditions of recall (general, happy, sad, anger, fear, and wonder). Subjects were asked to recall personal experiences from childhood and to rate their current mood and the affective intensity of the memories. The results indicated that repressors recalled significantly fewer negative memories than did low-anxious and high-anxious subjects and, furthermore, that they were substantially older at the time of the earliest negative memory recalled. Compared with low-anxious subjects, repressors also recalled fewer positive affective memories as well. This pattern of findings is consistent with the hypothesis that repression involves an inaccessibility to negative emotional memories and indicates further that repression is associated in some way with the suppression or inhibition of emotional experiences in general. The concept of repression as a process involving limited access to negative affective memories appears to be valid.     

Behavioural interventions in coping with cancer-related pain

Pain is one of the most feared consequences of cancer, often causing significant psychological distress to the patient. The purposes of this paper are (a) to discuss the psychological implications of cancer-related pain, (b) to offer conceptual explanations of the roles behavioural interventions mayplay in reducing cancer-related pain, and (c) to review studies examining the effectiveness of behavioural interventions in reducing cancer-related pain. Clinical issues raised by recent research are addressed, and suggestions for future research are offered. It is concluded that behavioural techniques may serve as a useful adjunct to traditional medical interventions for cancer pain, although considerably more methodologically rigorous research is needed to determine the nature and extent of treatment efficacy.     

The reconstruction of static visual forms from sparse dotted samples

This study explored the ability of observers to recognize very sparsely sampled, stereoscopic, dotted surfaces. The observers’ performance exceeded that of a simple surface-fitting algorithm that served as a first approximation model to the solution of the perceptual problem. We explored various attributes ofthe stimulus surfaces, but were unable to find any single attribute that could account for the measured performance. Therefore, we propose that the observers used several global surface attributes jointly to distinguish one form from another. Collectively, these attributes define what is meant by form in this study. We suggest that our results argue for a globally precedent, multidimensional model of form reconstruction as opposed to a local-feature, unidimensional interpretation.
