A new look at selective exposure

The relevance of the personality dimension “repression-sensitization” (D. Byrne in B. A. Maher (Ed.), Progress in experimental personality research, Vol. 1, NY: Academic Press, 1964, pp. 169–219) to selective exposure processes was investigated. Experimental repressors (who typically employ “avoidance” strategies in dealing with threatening stimuli) and experimental sensitizers (who generally “approach” threatening stimuli) were allowed to choose and keep one of two pairs of painting reproductions, each pair containing one positively and one negatively valued painting. After the decision, which experimental subjects believed terminated the experiment, subjects were allowed to inspect the alternatives ad libitum for 75 sec. Eye gaze during this period was unobtrusively videotaped. Compared to their matched controls, who were simply asked to inspect the paintings in order to decide which ones they liked best, experimental repressors inspected paintings that were consonant with their choices and avoided looking at paintings that were dissonant with their decisions. Experimental sensitizers did not manifest such postdecisional selective exposure. The implications of these results for past and future research on dissonance-produced selective exposure were discussed.     

Spatial memory in the rat on a hierarchical maze

Rats were trained and tested on a hierarchical radial maze, which consisted of eight primary alleys radiating from a central platform and three secondary alleys which branched off the end of each primary alley. In four experiments, rats in groups 1, 2, and 3 were tested on maze configurations consisting of one, two, or three secondary alleys, respectively, at the end of each primary alley. In Experiment 1, each group was trained to collect food pellets in the secondary alleys. By the end of training, rats in each group collected all pellets efficiently, with little repetition of entrances into either primary or secondary alleys. In Experiments 2 and 3, tests were carried out which required retention of entrances into secondary alleys, as well as primary alleys. Two trials were run in succession, with selected secondary alleys blocked on trial 1 but open and baited with food on trial 2. Animals in groups 2 and 3 showed very accurate retention of blocked secondary alleys, regardless of variation in pattern and number of alleys blocked. A fourth experiment controlled for the possible use of food cues in Experiments 2 and 3 by rebaiting all secondary alleys between trials 1 and 2. Subjects continued to choose previously blocked alleys on trial 2, thus demonstrating that choice of blocked alleys was based on memory and not on a tendency to approach visual or olfactory food cues. Several findings of these experiments suggest that memories for primary and secondary alley choices are encoded and stored within separate memory systems. Possible coding mechanisms for these systems are discussed with reference to a process of cognitive mapping.

Atmospheric memories: Affect and minor politics at the ten-year anniversary of the London bombings

This paper addresses how the ten-year anniversary of the London bombings was made present through political affects and atmospheres on 7 July 2015. Although the anniversary of a terrorist event forms an opportune moment for invoking the nation as united in feeling, we are interested in how people attune to political atmospheres of memory and trauma in multiple ways, which do not always cohere to sovereign narratives about unity and certainty. By focusing on these events through an attentiveness to the atmospheric and affective, we examine how these events were recalled, memorialised, felt and sensed in the small-scale ceremonies taking place across London on that morning, by way of a multi-authored sensory auto-ethnography. As such, we are led towards various moments of encounter, which involve ‘minor gestures’ (Manning, 2016), and imply ways of responding to acts of terror that rub against the unifying forces of the state. In contrast to the ‘rolling maelstroms of affect’ (Thrift 2004: 57) pursued by the state and media following a terrorist attack, this project is attentive to multiple, uncertain and ambivalent encounters. These matter because they suggest other ways of being political and of responding to both terrorist and state-led violence.     

Thinking around the corner: the development of planning abilities

The ability to plan and search ahead is essential for problem solving in most situations in everyday life. To investigate the development of planning and related processes, a sample of four- and five-year-old children was examined in a variant of the Tower of London, a frequently used neuropsychological assessment tool of planning abilities. The applied problems either required searching ahead for optimal solution or were solvable by pure step-by-step forward processing. Furthermore, the ambiguity of subgoal ordering was varied.Results revealed an age-related effect of search depth: the four-year olds’ planning accuracy was particularly decreased in problems demanding search ahead, while five-year olds mastered both problem types equally well. Interestingly, this interaction between age and search depth could not be accounted for by measures of working memory and inhibition. Differential effects of age were also found for subgoal ordering with respect to initial planning and movement execution times. In sum, planning abilities showed considerable development during late kindergarten age that appeared to be specifically associated with the integration and back-validation of the anticipated consequences of internally modeled actions. The present study demonstrates that a careful consideration of problem structure may greatly enhance the insights gained from the application of a routinely used assessment tool, the Tower of London. This may be especially advantageous when addressing specific subpopulations such as children or clinical samples.     

Silent No Longer

This article, arising from the work of the Council for World Mission's Legacies of Slavery project, investigates the historical roots of racism present in the work of the London Missionary Society (LMS). It offers an analysis of the ways in which a missionary society colluded with Empire in constructing a racist hierarchy that it imposed on White people at home in the United Kingdom as much as it did on African and African descendant peoples. It acknowledges the personal and structural benefits that the LMS and its officers made from enslavement and their efforts to silence calls for emancipation, and offers a class and gender perspective on the forces shaping this distinctively British organization.     

INTRODUCTION to Special Edition of JAP on the ‘Who is My Jung?’ conference held at the British Library in October 2017 to mark the 40th Anniversary of the foundation of the Association of Jungian Analysts (AJA)

The paper reviews the processes which went into the creation of an exceptionally comprehensive conference on Jungian analysis and psychology. The conference brought together all five of the constituent societies based in London of the International Association for Analytical Psychology (IAAP). The personal nature of the conference contributions is highlighted together with observations about the passage from spoken to written modes. The idea of ‘conference space’ is reviewed and this leads to a discussion of the often overlooked benign role of conferences in professional life.

The immediate and sustained effects of acute exercise on planning aspect of executive function

ObjectiveThe purpose of this study was to clarify the immediate and sustained effects of an acute bout of exercise on the planning aspects of executive function.DesignThis study used a 2 × 4 true experimental design.MethodForty participants were randomly assigned to either the exercise or control groups and completed the Tower of London task prior to, immediately following, 30 min after, and 60 min after cessation of a 30 min, moderate intensity cycling exercise.ResultsAcute exercise positively impacted the total move score, which reflects planning efficiency, immediately after the cessation of exercise. Acute exercise also led to longer total initiation times, which were linked to better response inhibition of planning at 30 and 60 min after the cessation of exercise.ConclusionAcute exercise benefits planning, and the types of planning and the time points at which they were assessed modulate the relationship between acute exercise and executive function. Exercise-induced physiological and biological fluctuations have been proposed to explain the effects present immediately after exercise, and the mechanisms of such effects warrant further exploration.
