What is so frightening about spiders? Self‐rated and self‐disclosed impact of different characteristics and associations with phobia symptoms

Spider phobia is a common and impairing mental disorder, yet little is known about what characteristics of spiders that spider phobic individuals find frightening. Using screening data from a clinical trial, we explored which characteristics that spider‐fearful individuals (n = 194) rated as having the greatest impact on fear, used factor analysis to group specific characteristics, and explored linear associations with self‐reported phobia symptoms. Second, a guided text‐mining approach was used to extract the most common words in free‐text responses to the question: “What is it about spiders that you find frightening?” Both analysis types suggested that movement‐related characteristics of spiders were the most important, followed by appearance characteristics. There were, however, no linear associations with degree of phobia symptoms. Our findings reveal the importance of targeting movement‐related fears in in‐vivo exposure therapy for spider phobia and using realistically animated spider stimuli in computer‐based experimental paradigms and clinical interventions such as Virtual Reality exposure therapy.     

AUGMENTED REALITY,ARTIFICIAL INTELLIGENCE,AND THE RE‐ENCHANTMENT OF THE WORLD

There has recently been a surge of development in augmented reality (AR) technologies that has led to an ecosystem of hardware and software for AR, including tools for artists and designers to accelerate the design of AR content and experiences without requiring complex programming. AR is viewed as a key “disruptive technology” and future display technologies (such as digital eyewear) will provide seamless continuity between reality and the digitally augmented. This article will argue that the technologization of human perception and experience of reality, coupled with the development of artificial intelligence (AI)–based natural language assistants, may lead to a secular re‐enchantment of the world, in the sense outlined by Charles Taylor, where human existence is shaped through AR inhabited by advanced personal and social AI agents in the form of digital avatars and daemons, and that enchantment has been persistent throughout the formation of modernity and is being rekindled by the integration of AI in the plane of AR.     

Children's recall and source monitoring of a repeated event using a timeline as an interview aid

Investigators sometimes use timelines (visual depictions of time) to help children identify temporal information from experienced events or details from a particular instance of a repeated event. However, little is actually known about the efficacy of this visual aid on children's memories. Six‐ to 9‐year‐olds participated in four occurrences of a repeated event and were later interviewed with or without the use of a timeline. Children in the timeline condition were less accurate and made more source‐monitoring errors than those in the control condition. For items that appeared consistently throughout the events, a suggestibility effect was more evident for older children who used the timeline than those who did not. Overall, there was no clear evidence in support of the visual aid. Despite its popularity, our findings suggest that timelines should be further examined to establish whether, and under what circumstances, they might be used in investigative contexts.     

Did you wash your hands? Evaluating memory for objects touched by healthy individuals and individuals with contagious and noncontagious diseases

Prior research suggests that individuals recruit a disease‐avoidance system designed to avoid sources of illness through threat detection and memory. Our study evaluated whether disease‐related memory benefits reflect the distinctive/salient nature of a diseased state versus the infectious nature of a disease by comparing memory for objects touched by healthy individuals or those with a contagious or noncontagious disease. Participants studied videos depicting an actor interacting with objects in which the actor was described as diagnosed with influenza, an infectious disease, cancer, a noninfectious disease, or was healthy, followed by free‐recall and source‐recognition tests. Correct recall and source recognition were greater overall for touched versus nontouched items, but source recognition was particularly elevated for items touched by the infectious influenza actor. Further, touched‐item recognition was positively related to participants' assessed germ aversion—supplemental evidence that disease concerns may facilitate source recollections for touched objects.     

The impact of surface projection on military tactics comprehension

This experiment assessed how displaying information onto different surfaces (flat vs. raised) influenced the performance, workload, and engagement of cadets answering questions on military tactics. Sixty-two cadets in a within-subjects design each answered 24 tactics-related questions across 2 conditions (12 on flat, 12 on raised) which were measured by accuracy and time on task. After each set of 12 questions, the cadets took postsurveys assessing engagement, measured by a modified User Engagement Scale and the System Usability Scale, and workload measured by the NASA-TLX. Findings indicated that raised terrain surface led to reduced workload and increased engagement and time on task as compared to the flat terrain surface. A practice effect drove performance metrics (time on task and accuracy), where the learner performed better on the second surface type displayed. This research contributes to expanding the literature base that supports alternative display methods to increase engagement and augment instruction of military tactics tasks.

The predicting brain: Unconscious repetition, conscious reflection and therapeutic change

Neuroscience indicates that 'repetition' is fundamental to brain function. The brain non-consciously predicts what is most likely to happen and sets in motion perceptions, emotions, behaviors and interpersonal responses best adapted to what is expected-before events occur. Predictions enable individuals to be ready 'ahead of time' so reactions occur rapidly and smoothly when events occur. The brain uses past learning as the guide for what to expect in the future. Because of prediction, present experience and responses are shaped by the past. Predictions from early life can be deeply encoded and enduring. Predictions based on the past allow for more efficient brain function in the present, but can lead to mistakes. When what is predicted does not occur, consciousness can be engaged to monitor and correct the situation. But if a perception or emotion seems reasonable for the situation, a person might not notice an error, and a maladaptive 'repetition' may remain unchanged. The author discusses how predictions contribute to psychological defenses and transference repetition, and how conscious self-reflection facilitates therapeutic change. The neuroscience of prediction indicates why, in certain cases, active engagement by the analyst may be necessary. The author makes the argument for use of a 'neuroscience interpretation'.     

Impact of a comprehensive safety program on bicycle helmet use among middle-school children

A bicycle helmet program was evaluated in three middle schools using a multiple baseline across schools design. Two of the three schools had histories of enforcement of helmet use. During baseline many students riding their bikes to and from school did not wear their helmets or wore them incorrectly. A program that consisted of peer data collection of correct helmet use, education on how to wear a bicycle helmet correctly, peer goal setting, public posting of the percentage of correct helmet use, and shared reinforcers, all of which were implemented by the school resource officer, increased afternoon helmet use and afternoon correct helmet use in all three schools. Probe data collected a distance from all three schools indicated that students did not remove their helmets once they were no longer in close proximity to the school, and probe data collected in the morning at two of the schools showed that the behavior change transferred to the morning.
