Source Handler telephone interactions with covert human intelligence sources: An exploration of question types and intelligence yield

Law Enforcement Agencies gather intelligence in order to prevent criminal activity and pursue criminals. In the context of human intelligence collection, intelligence elicitation relies heavily upon the deployment of appropriate evidence-based interviewing techniques (a topic rarely covered in the extant research literature). The present research gained unprecedented access to audio recorded telephone interactions (N = 105) between Source Handlers and Covert Human Intelligence Sources (CHIS) from England and Wales. The research explored the mean use of various question types per interaction and across all questions asked in the sample, as well as comparing the intelligence yield for appropriate and inappropriate questions. Source Handlers were found to utilise vastly more appropriate questions than inappropriate questions, though they rarely used open-ended questions. Across the total interactions, appropriate questions (by far) were associated with the gathering of much of the total intelligence yield. Implications for practise are discussed.     

What is learned from experience in a probabilistic environment?

Three experiments explored what is learned from experience in a probabilistic environment. The task was a simulated medical decision‐making task with each patient having one of two test results and one of two diseases. The test result was highly predictive of the disease for all participants. The base rate of the test result was varied between participants to produce different inverse conditional probabilities of the test result given the disease across conditions. Participants trained using feedback to predict a patient's disease from a test result showed the classic confusion of the inverse error, substituting the forward conditional probability for the inverse conditional probability when tested on it. Additional training on the base rate of the test result did little to improve performance. Training on the joint probabilities, however, produced good performance on either conditional probability. The pattern of results demonstrated that experience with the environment is not always sufficient for good performance. That natural sampling leads to good performance was not supported. Further, because participants not trained on joint probabilities did, however, know them but still committed the confusion of the inverse error, the hypothesis that having joint probabilities would facilitate performance was not supported. The pattern of results supported the conclusion that people learn all the necessary information from experience in a probabilistic environment, but depending upon what the experience was, it may interfere with their ability to recall to memory the appropriate sample set necessary for estimating or using the inverse conditional probability.

John Nash: Three Phases in the Career of a Beautiful Mind

This article is the Helen Flanders Dunbar Lecture presented at Columbia-Presbyterian Hospital in New York City in 2002, the centennial year of her birth. It focuses on three periods in the evolution of Nash’s mental illness, the predelusional, delusional, and postdelusional periods, and provides a psychoanalytic interpretation of each. Donald Capps is Professor of Pastoral Psychology at Princeton Theological Seminary. His books include Men, Religion, and Melancholia (1997), Living Stories: Pastoral Counseling in Congregational Context (1998), Social Phobia: Alleviating Anxiety in an Age of Self-Promotion (1999), Jesus: A Psychological Biography (2000), Giving Counsel: A Minister’s Guidebook (2001), Men and Their Religion: Honor, Hope, and Humor (2002), and A Time to Laugh: The Religion of Humor (2005).

Time course of effects of emotion on item memory and source memory for Chinese words

Although many studies have investigated the effect of emotion on memory, it is unclear whether the effect of emotion extends to all aspects of an event. In addition, it is poorly understood how effects of emotion on item memory and source memory change over time. This study examined the time course of effects of emotion on item memory and source memory. Participants learned intentionally a list of neutral, positive, and negative Chinese words, which were presented twice, and then took test of free recall, followed by recognition and source memory tests, at one of eight delayed points of time. The main findings are (within the time frame of 2 weeks): (1) Negative emotion enhances free recall, whereas there is only a trend that positive emotion enhances free recall. In addition, negative and positive emotions have different points of time at which their effects on free recall reach the greatest magnitude. (2) Negative emotion reduces recognition, whereas positive emotion has no effect on recognition. (3) Neither positive nor negative emotion has any effect on source memory. The above findings indicate that effect of emotion does not necessarily extend to all aspects of an event and that valence is a critical modulating factor in effect of emotion on item memory. Furthermore, emotion does not affect the time course of item memory and source memory, at least with a time frame of 2 weeks. This study has implications for establishing the theoretical model regarding the effect of emotion on memory.     

Adversarial attacks against profile HMM website fingerprinting detection model

People are accustomed to using an anonymous network to protect their private information. The Profile HMM (Hidden Markov Model) Website Fingerprinting Detection algorithm can detect the website that the data stream accesses by pattern matching the captured data traffic. This makes the anonymous network lose its effect. In order to bypass the detection of this model, we propose a method based on genetic algorithm to generate adversarial samples. By migrating the problem of adversarial samples in deep learning, our approach is used for the broader machine learning detection model to do traffic confusion, and then achieves the purpose of bypassing the Profile HMM model detection. The key challenge is how to construct a suitable fitness function to generate an effective adversarial sample at minimal cost. The experimental results show that the success rate of our traffic confusion method is as high as 97%. At the same time, we only need to add less perturbation traffic than the traditional traffic confusion method.     

The relationship between theory of mind and episodic memory: evidence for the development of autonoetic consciousness

The study investigated a link between theory of mind and episodic memory involving autonoetic consciousness (). Eighty-nine Japanese 4- to 6-year-olds received two versions of a false belief task, a task of aspectuality or knowledge origins, and four memory tests. After controlling for age, most theory of mind abilities showed no interrelations, and own and other's belief understandings in deceptive appearance tasks were solely related to source memory, but not to free recall, temporal ordering, or working memory. Moreover, even when age and verbal intelligence were controlled, the association between representational change and source memory was highly significant in 6-year-olds but not in 4- and 5-year-olds. Results suggest that during development only a particular kind of theory of mind ability is integrated with episodic memory.     

A close-up comparison of the misclassification error distance and the adjusted Rand index for external clustering evaluation

The misclassification error distance and the adjusted Rand index are two of the most common criteria used to evaluate the performance of clustering algorithms. This paper provides an in-depth comparison of the two criteria, with the aim of better understand exactly what they measure, their properties and their differences. Starting from their population origins, the investigation includes many data analysis examples and the study of particular cases in great detail. An exhaustive simulation study provides insight into the criteria distributions and reveals some previous misconceptions.     

The development of automatic associative processes and children’s false memories

We investigated children’s ability to generate associations and how automaticity of associative activation unfolds developmentally. Children generated associative responses using a single associate paradigm (Experiment 1) or a Deese/Roediger–McDermott (DRM)-like multiple associates paradigm (Experiment 2). The results indicated that children’s ability to generate meaningful word associates, and the automaticity with which they were generated, increased between 5, 7, and 11 years of age. These findings suggest that children’s domain-specific knowledge base and the associative connections among related concepts are present and continue to develop from a very early age. Moreover, there is an increase in how these concepts are automatically activated with age, something that results from domain-general developments in speed of processing. These changes are consistent with the neurodevelopmental literature and together may provide a more complete explanation of the development of memory illusions.     

SPIRITUAL TRANSFORMATION AS THE AWAKENING OF GLOBAL CONSCIOUSNESS: A DIMENSIONAL SHIFT IN THE TECHNOLOGY OF MIND

Abstract. Great spiritual and philosophical traditions through the ages have sought to tap and articulate the grammar or logic of the fundamental unified field that is the common generative ground of our diverse worldviews, religions, cultures, ideologies, and disciplinary languages. I suggest that we are in the midst of a profound dimensional shift in our rational capacity to process reality, and I seek to articulate the implications of this evolutionary shift to global reason and awakened consciousness for all aspects of our human and rational enterprise. It is clear that we are in the midst of an unprecedented shift in the human condition—a global renaissance that affects every aspect of our cultural lives, self‐understanding, experience, and world making. This evolutionary transformation, when seen through the dilated global lens, has been emerging through the ages on a global scale. I suggest that this advance in our technology of mind is of an order of magnitude that is so radical and comprehensive that the very concept of a person, of what it means to be human, of our encounter with Reality, and of all our hermeneutical arts including the sciences are likewise taken to a higher, global, dimension. I explore this emergent grammar of spiritual transformation to global, dialogic, integral, and holistic consciousness, the global awakening of reason, scientific knowing, and the holistic worldview.     

Negative emotion elicited in high school students enhances consolidation of item memory,but not source memory

The study examined the effect of negative emotion on consolidation of both item and source memory. Participants learned words read by either a male or female. Then they watched either a negative or a neutral video clip. Memory tests were carried out either 25 min or 24 h after learning. The study yielded the following findings. First, negative emotion enhanced consolidation of item memory as measured by recognition memory in the 25-min delay, and enhanced consolidation of item memory as measured by free recall in both the 25-min and the 24-h delay. Second, negative emotion had little effect on consolidation of source memory, either in the 25-min or the 24-h delay. These findings provide evidence for the differential effects of negative emotion on item memory and source memory and have implications for using emotion as a strategy to intervene memory consolidation.
