Some adrenal correlates of aggression in isolated female mice

Forty-six female mice (CFW) were isolated for a period of 23 weeks. The effect of isolation on fighting behavior was tested weekly by introducing a naive brown female mouse into the subject's home cage. Total leucocyte counts were obtained at 8 and 14 weeks of isolation. The appearance of leucopenia was used as an index of elevated adrenocortical activity. After 23 weeks of isolation all animals were sacrificed by decapitation. Plasma was collected for corticosterone assay, and paired adrenals were used to assay catecholamine levels. On the basis of the frequency and/or the absence of fighting, the mice were segregated into fighters (n = 22) and non-fighters (n = 17). Analysis of the data by Pearson's product moment correlation and Student's t-test showed that elevated sympathetic-adrenal activity was positively correlated with aggression and that elevated adrenocortical activity was negatively correlated with aggression.     

COVID-19, precarity and loneliness

In this paper I discuss Jungian psychological work of the trauma and loss experienced in reaction to COVID-19 with a man who represents a clinical composite. The issues of precarity, a concept used by the philosopher Judith Butler, are combined with the notions of lack and absence of French psychoanalyst André Green. The psychological and societal situation of precarity aroused the man’s childhood issues that were long repressed. The loneliness, isolation and death from COVID-19 mirrored his personal and the collective responses to the disaster from this global pandemic. He felt on the edge of collapse as what he knew of his world crashed and he found himself unable to cope. The subsequent Jungian work taking place through the virtual computer screen was taxing and restorative simultaneously for both analyst and analysand.     

Efficacy and social validity of procedures for improving conversational skills of college students with autism

Better conversational skills correspond to a higher quality of life for adults diagnosed with autism spectrum disorder (ASD). In this study, we taught vocal–verbal responses discriminated by compound arrangements of concealed conversation partner mands to two college students with ASD. Participants learned to engage in self-questioning about their conversation partner's behavior and to reinforce three concealed mands for termination of an aversive conversation scenario. We assessed generalization to conversation probes with trained confederates and to interactions with untrained conversational partners (e.g., peers, professors). Finally, we collected peer ratings of the social validity of changes in conversational behavior as well as participants' ratings of study goals, procedures, and outcomes.     

Narrative access and production in preschoolers' false belief reasoning

False belief tests seem to show the apparent acquisition at around age 4 of an ability to understand the representational status of mind. In this article, preschoolers' performance on a false belief task was manipulated in terms of their grasp of its narrative base. Five experiments are reported in which 3-year-olds were helped to become familiar with the events that comprise the false belief procedure by going through a picture book version of the task, before being asked to judge the protagonist's mental state. In Experiment 1, children who had failed a traditional task succeeded if they narrated the book version back to the experimenter, particularly if they were fluent in their story recall. Experiment 2 showed that this success occurred either if the child recited the story or if she or he was taken through each page twice in succession. Experiment 3 combined the most effective procedures with a younger group of children (mean age 3;3) and revealed 95% success as long as they could recall the prerequisite events. Experiments 4 and 5 probed possible limiting conditions for success by inserting an extra episode in the story and changing the format of the test question. The results suggest that the structure of 3-year-olds' event memories is central to their poor performance in the traditional false belief task—a clear grasp of the false belief “narrative” is necessary for successful performance. When they are given the opportunity to link discrete events into a coherent narrative, they have no problem demonstrating an understanding of others' minds—being able to recount the narrative is sufficient for successful performance.     

The Importance of Construct Validity in Consumer Research

Vosgerau, Scopelliti, and Huh (2020) question the construct validity of the most commonly used measures of self‐control and argue that many studies that claim to be examining self‐control may in fact be examining something else. In this comment, we generalize this argument and propose that this criticism could be leveraged against many other areas of consumer research. Indeed, many studies fail to properly establish the construct validity of their measures. Consequently, they may not be examining the construct they purport to be studying, which can lead to unreliable and conflicting findings.     

Effects of Stimulant Medication Treatment on Mothers' and Children's Attributions for the Behavior of Children with Attention Deficit Hyperactivity Disorder

Participants were 55 children with attention deficit hyperactivity disorder (ADHD) who were receiving ongoing treatment with stimulant medications and their mothers, and 31 children with ADHD who were beginning stimulant medication and their mothers. Mothers and children offered attributions for child behaviors that occurred when the child was medicated and not medicated. Mothers rated child compliance and prosocial behavior as more global and stable when the child was medicated and rated noncompliance, ADHD symptoms, and oppositional behavior as more externally caused, less global and stable, but more controllable by the child when the child was medicated. Children rated both their compliance and noncompliance as more controllable in the medicated condition. On a forced-choice measure, both mothers and children selected ability, effort, and task attributions for compliance more in the not-medicated condition, and pill-taking attributions more in the medicated condition. This was reversed for noncompliance, which was attributed more to effort, task, or ability in the medicated condition and more to not taking a pill in the not-medicated condition. The potential risks and benefits for parent–child interactions and children's self-perceptions of these medication-related differences in attributions are discussed.
