To know where the bodies are buried: The use of the cognitive interview in an environmental scale spatial memory retrieval task

Missing body homicide cases have gained public interest globally due to some high-profile cases. In many of these cases, the task of locating the victim's remains relies on the information investigators can gain through the interviewing of willing suspects. To date, investigative interviewing research has largely focused on the retrieval of episodic memory (events) without focusing on spatial memory, a prominent cognitive task required in locating a victim's remains. The current experiment tests the enhanced cognitive interview (ECI) against a free recall strategy in a mock homicide scenario where participants are required to hide and retrieve an object in a natural bushland setting. The results showed that those in the ECI condition produced more coarse- and fine-grained details of landmarks and their actions at and journeying to the deposition site. This demonstrates the value of using the ECI in generating more valuable information to assist in successive search attempts.     

Executive Career Counselling

Executive career counselling is relatively new. Some of its implications are examined and a three-tiered approach by organisations is advocated. Executives are verbally fluent, and this highlights the importance of the 'opening paragraph' of words they use in counselling. Neuro-linguistic programming offers a useful set of tools to the executive career counsellor. Left-handedness, probably overlooked in most types of counselling, is briefly considered. However, counselling is not only about problems, but also offers executives a welcome chance to review their lives and careers.     

Beliefs and inferences: A test of a rational-emotive hypothesis 1. Performing in an academic seminar

Subjects were asked to imagine that they were going to present an academic seminar. They were further asked to imagine (a) that they adhered to a rational belief or an irrational belief; (b) that they had made or had not made an effort in preparing for the seminar and (c) that their performance counted or did not count towards their final examination grade. Whilst in role, subjects were asked to make inferences about various aspects of their performance and the responses of others. While the results supported the hypothesis that imagining that one is holding an irrational belief leads to more negative inferences than holding a rational belief, it was also found that not making an effort in preparing for the siminar led subjects to make more negative inferences than making an effort. In addition, there were several two-way and three-way significant interactions between the independent variables. The results supported Ellis's (1985) recent formulation concerning the complex relationship between events and inferences (A), beliefs (B) and emotional and behavioral consequences of beliefs (C).Windy Dryden PhD is Senior Lecturer in the Department of Psychology, Goldsmiths' College, University of London, England.

The Role of Intentions, Social Norms, and Attitudes in the Performance of Dental Flossing: A Test of the Theory of Reasoned Action

The theory of reasoned action proposed by Fishbein and Ajzen (1975) was tested as an explanatory model for a preventive dental behavior, dental flossing, in a sample of 65 undergraduate students. Intentions and direct attitudes were found to be the strongest predictors of flossing. Social influences exerted their influence by way of direct attitudes. Flossers (>1/week) and non-flossers (<1/week) were observed to agree with belief statements referring to the health value of flossing. However, statements referring to the social and sensory aspects of flossing were found to effectively discriminate the two groups. Implications for health education strategies are discussed in which a greater focus is placed on more immediate social and sensory benefits of flossing rather than on long-term health benefits.     

Scotching the Dutch Book Argument

Consistent application of coherece arguments shows that fair betting quotients are subject to constraints that are too stringent to allow their identification with either degrees of belief or probabilities. The pivotal role of fair betting quotients in the Dutch Book Argument, which is said to demonstrate that a rational agent's degrees of belief are probabilities, is thus undermined from both sides.     

Classical harmony: Rules of inference and the meaning of the logical constants

The thesis that, in a system of natural deduction, the meaning of a logical constant is given by some or all of its introduction and elimination rules has been developed recently in the work of Dummett, Prawitz, Tennant, and others, by the addition of harmony constraints. Introduction and elimination rules for a logical constant must be in harmony. By deploying harmony constraints, these authors have arrived at logics no stronger than intuitionist propositional logic. Classical logic, they maintain, cannot be justified from this proof-theoretic perspective. This paper argues that, while classical logic can be formulated so as to satisfy a number of harmony constraints, the meanings of the standard logical constants cannot all be given by their introduction and/or elimination rules; negation, in particular, comes under close scrutiny.     

Isobias curves in some detection tasks

Signal/noise ratio was varied in three tone-detection tasks while other conditions were held constant, generating 9 8-point and 12 12-point isobias plots. These plots were compared with the theoretical isobias curves associated with seven proposed bias measures. Each of the proposed measures covaried with signal/noise ratio in at least half of the data. For two of the plots, none of the measures was invariant. It is clear that different subjects respond quite differently to change in discriminability, and the implications of this for bias measurement are discussed.
