Information on the Internet: How selective should we be?

Vast amounts of information are available on the Internet, and programs such as Mosaic provide users with easy access to text and multimedia files. Once a user has set up a host system, consideration must be given to what information will be made available. In addition to legal restrictions, the interests of potential users (those accessing the host system) should be considered when determining the kinds of information to be made available. If those maintaining these host systems are somewhat selective when making information availability decisions, the potential information “glut” may be attenuated.     

How do ordered questions bias eyewitnesses?

ABSTRACT

Background: Suggestive techniques can distort eyewitness memory (Wells & Loftus, 2003, Eyewitness memory for people and events. In A. M. Goldstein (Ed.), Handbook of psychology: Forensic Psychology, Vol. 11 (pp. 149–160). Hoboken, NY: John Wiley & Sons Inc). Recently, we found that suggestion is unnecessary: Simply reversing the arrangement of questions put to eyewitnesses changed what they believed (Michael & Garry, 2016, Ordered questions bias eyewitnesses and jurors. Psychonomic Bulletin & Review, 23, 601–608. doi:10.3758/s13423-015-0933-1). But why? One explanation might be that early questions set an anchor that eyewitnesses then adjust away from insufficiently. Methods: We tracked how eyewitness beliefs changed over the course of questioning. We then investigated the influence of people’s need to engage in and enjoy effortful cognition. This factor, “Need for Cognition,” (NFC) affects the degree to which people adjust (Cacioppo, Petty, & Feng Kao, 1984, The efficient assessment of need for cognition. Journal of Personality Assessment, 48, 306–307. doi:10.1207/s15327752jpa4803_13; Epley & Gilovich, 2006, The anchoring-and-adjustment heuristic: Why the adjustments are insufficient. Psychological Science, 17, 311–318. doi:10.1111/j.1467-9280.2006.01704.x). Results: In our first two experiments we found results consistent with an anchoring-and-adjustment account. But in Experiments 3 and 4 we found that NFC provided only partial support for that account. Conclusions: Taken together, these findings have implications for understanding how people form beliefs about the accuracy of their memory.     

Hypnotic interviewing: the best way to interview eyewitnesses?

It has been suggested that hypnosis techniques may have the potential to enhance eyewitness memory in forensic investigations. However, laboratory research shows that increases in recall with hypnosis techniques are often associated with decreases in accuracy, false confidence in incorrect information, and increased suggestibility to leading questions and misleading post-event information. These problems limit the usefulness of hypnosis as an interviewing procedure. However, in practical investigations, many factors associated with hypnosis, apart from the hypnotic induction itself, might lead to memory enhancement compared with standard police interviews. For example, hypnotic interviewers, because of their psychological, clinical, and interpersonal skills, may be better interviewers than police officers. They may use effective interviewing strategies such as those associated with the “cognitive interview”; a procedure which has the potential to enhance recall by approximately 35% without the problems of memory distortion associated with hypnosis. It is concluded, therefore, that a cognitive interview procedure should be used in preference to hypnosis. © 1998 John Wiley & Sons, Ltd.     

How should we revise diagnostic criteria for substance use disorders in the DSM-V?

This article reviews literature on the validity and performance characteristics of the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) diagnostic criteria for substance use disorders (SUDs) and recommends changes in these criteria that should be considered for the next edition of the DSM (DSM-V). Substantial data indicate that DSM-IV substance abuse and substance dependence are not distinct categories and that SUD criteria are best modeled as reflecting a unidimensional continuum of substance-problem severity. The conceptually and empirically problematic substance abuse diagnosis should be abandoned in the DSM-V, with substance dependence defined by a single set of criteria. Data also indicate that various individual SUD criteria should be revised, dropped, or considered for inclusion in the DSM-V. The DSM-V should provide a framework that allows the integration of categorical and dimensional approaches to diagnosis. Important areas for further research are noted.     

How should utilitarians think about the future?

Abstract

Utilitarians must think collectively about the future because many contemporary moral issues require collective responses to avoid possible future harms. But current rule utilitarianism does not accommodate the distant future. Drawing on my recent books Future People and Ethics for a Broken World, I defend a new utilitarianism whose central ethical question is: What moral code should we teach the next generation? This new theory honours utilitarianism’s past and provides the flexibility to adapt to the full range of credible futures – from futures broken by climate change to the digital, virtual and predictable futures produced by various possible technologies.     

What should we expect after the next attack?

A test of any science is its ability to predict events under specified conditions. A test for the psychology represented in this special issue of the American Psychologist is its ability to predict individual and social behavior in the aftermath of a next terror attack. This article draws on that science to make such predictions. These predictions are conditioned on both the nature of the attack and our institutional preparations for it. Some attacks will test our resilience more than others. Whatever the attack, we will reduce its impacts if our institutions take advantage of psychological science. That science can reduce the scope of attacks by limiting terrorists' ability to organize their operations and by enhancing our ability to restrain them. It can reduce the impacts of any attacks that do occur by strengthening the institutions and civil society that must respond to them. Realizing these possibilities will require our social institutions to rely on science, rather than intuition, in dealing with these threats. It will require our profession to provide psychologists with rewards for public service, applied research, and interdisciplinary collaboration, as demanded by complex problems. Responding to these challenges could strengthen society and psychology.     

The computer psychiatrist: How far have we come? Where are we heading? How far dare we go?

The use of computers in psychiatry and psychology is reviewed. It is noted that computers are already being used successfully for consultation, interviewing, and continuing education. Issues related to the usage of computers in mental health are discussed. Guidelines for future work in the area are suggested.     

Change: How do we recognize it?

The paper seeks to examine the working assumptions that guide us as therapists engaged in the attempt to facilitate change in families. It summarizes a piece of preliminary research based on the responses of a group of therapists working in different agencies. A questionnaire on change was developed and given to the therapists followed by a group discussion.
The results suggest that therapy teams, and families, have common sense ideas about:

• the beginning, and end of a period of change;

• types of change—those falling into four categories; of behavioural, structural, communication and experiential.

Our results suggest that difficulties in therapy may be associated with a failure amongst the therapists in a team to negotiate their mutual assumptions about change. In addition the process of therapeutic change is seen as involving a negotiation between the family and the therapists about what will count as change.
The data were gathered from a group of therapists attending a local meeting of the Association for Family Therapy in Plymouth.     

Wrestling with the future: should we test children for adult-onset genetic conditions?

Genetics professionals have been reluctant to test children for adult-onset conditions because they believe this would create psychosocial harm to children not counterbalanced by significant benefits. An additional concern they express is that such testing would violate the autonomy of these children as adults. Yet weighing the harms and benefits of such testing results in a draw, with no substantial harms proven. Moreover, such testing can enhance, rather than violate the adult autonomy of these children. In deciding whether to proceed with predictive testing of children, parents, mature children, and health care professionals should consider a complex of factors relevant to the particular child. The importance of these factors will vary depending on the condition at issue, the age and stage of development of the child, family dynamics, and the concerns, values, and objectives of the parents and mature child. The final decision whether to test a child for an adult-onset condition should rest with the parents and the mature child.     

Concerted Creativity in the Digital Age: How do we Crack the Code…?

The purpose of the present article is to contribute to the development of a socio-material, situated conceptualization of creativity, in exploring music making as it becomes meaningful in performative emergence processes of the digital age. It uses the creative practices of musicians to analyse and discuss the qualities of ‘digital materials’ in a creative setting, today very often playing a critical role in the production and performance of music. Methodologically, the analysis is based on interviews with professional musicians performing at Roskilde Festival and observations inspired by the autoethnographic approach. The study concludes that creative musical emergence in performance situations of the digital age depends on an openness towards a fragility, imperilling the situation and ‘cracking’ the digital materiality.
