The Influence of Delay and Item Difficulty in Criminal Justice Systems on Eyewitness Confidence and Accuracy
There is international concern about the negative effects of delays in Criminal Justice Systems. Problems include the deleterious effects that delay can have on witnesses' memory accuracy and witnesses' ability to calibrate their memories accurately. Little empirical work has been conducted on these issues combined with item difficulty and the relationship between accuracy and confidence. This paper investigates these issues. 21 witnesses were in…
Specialist police interviewer perceptions of the enhanced cognitive interview: Usefulness, confidence and witness reliability
Cognitive Interviews are recognised as best practise for investigative interviews of witnesses across relevant jurisdictions worldwide; though police officers’ perceptions of the usefulness of some Enhanced Cognitive Interview (ECI) components sit awkwardly with empirical findings. This paper examines 33 ECI specialist trained police officers’ views which showed ‘build rapport’ and ‘report everything’ perceived as most useful. Furthermore, the st…

What is hypnosis
Traditionally hypnosis has been viewed as an altered state of consciousness or trance, perhaps similar to sleep. However, recently a number of psychologists have questioned this view. Non-state theorists have argued that hypnosis can be adequately explained in terms of more ordinary psychological processes such as role enactment, imagination, relaxation, compliance, obedience, attention, distraction, and attitudes and expectations, without the ne…
Equality ratio equity, general linear equity and framing effects in judgments of allocation divisions
It is argued here that there is not necessarily a contradiction between the general linear and equal ratio approaches to equity, and the two may be integrated to make more precise predictions. It was hypothesized that, (a) equity is best represented by a limited equal ratio rule; (b) the more a linear distribution systematically deviates from equal input/outcome ratios, the more unfair it will be judged, but (c) subjects will prefer a distributio…
The influence of item difficulty on the relationship between eyewitness confidence and accuracy
Research indicates that the confidence eyewitnesses express in information heavily influences both the investigative process and the credence which jurors give to eyewitness testimony. However, studies in this area suggest that there is either no relationship or only a small positive relationship between eyewitness confidence and accuracy. Nevertheless, it is argued here that researchers may have paid insufficient attention to the issue of item d…
On the Roles of Control and Outcomes in Procedural Justice
Previous research has indicated that, in legal situations, regardless of trial outcome, an adversarial procedure may be preferred to an inquisitorial procedure because the former promotes a greater sense of control. This might suggest that fairness in procedures and fairness in outcomes are independent. Results presented here, however, indicated that, although an adversarial procedure was preferred to an inquisitorial one, when the specific issue…
Lay Causal Perceptions of Third World Poverty and the Just World Theory
This study investigated the factor analytic properties of Rubin and Peplau's (1975) Just World Scale and a questionnaire of possible causes of Third World poverty. Three Just World factors emerged in contrast to Hyland and Dann's (1987) four factor solution. They were interpreted as ‘Pro Just World’, Anti Just World' and 'Cynical or Reserved Just World Belief. Four poverty factors emerged, interpreted as ‘Blame the Poor; ‘Blame Third World Govern…
Conservatism and Achievement in Higher Education
A number of resarchers have suggested that measures of conservatism are significantly related to education, such that those with fewer years of education tend to hold more conservative values ( 1, 3). However, no research has yet been conducted to determine whether there is a plateau effect in those who are highly educated by conventional standards or whether discriminations can still be made. The present study was done to relate conservative val…
Political Ideology, Intelligence, Heredity and Social Justice: Is There a Paradox
Beliefs concerning the heritability of intelligence have long been associated with political views (1). However, if, as is sometimes claimed, political rightists tend to endorse the hereditarian position more than liberals or leftists, this appears to present a paradox, as rightists are also more likely to agree with notions such as most who don't succeed in life are just lazy, by and large, what they get, and almost anyone can be successful if h…
Attitudes to Poverty, the Protestant Ethic, and Political Affiliation: A Preliminary Investigation
This study investigated attitudes to the poor as measured by MacDonald's Poverty Scale and the Protestant Ethic Scale. Supporters of the British Conservative Party were found to have more negative attitudes to the poor, and were more likely to blame the poor for their fate than supporters of the British Labour Party. Supporters of the Liberal/SDP Alliance occupied position between the other two parties on this issue. These results accord with oth…
Attitudes to Sex-Roles, Political Conservatism and Belief in a Just World
The relationships between support of the traditional role of women in society, political conservatism, and the belief in a just world were investigated by means of a questionnaire given to 93 British undergraduate students. Significant positive relationships were found
Disorganized Recall, Suggested Amnesia, and Compliance
Spanos, Radtke-Bodorik, and Stam (1980) proposed that the phenomenon of disorganized recall in suggested amnesia cannot be accounted for in terms of behavioural compliance with task demands, as subjects simulating partial amnesia fail to show disorganization in recall. However, Spanos, et al. used a procedure which required simulators to recall specific numbers of items, and this may have required subjects to organize material to reach their targ…
Goal-Directed Fantasy, the Experience of Nonvolition, and Compliance
In a study of suggested arm levitation, Spanos and Barber (1972) concluded that subjects tended to experience suggestions as more non-volitional when instructed to engage in goal-directed fantasy. An attempt was made to test the viability of an interpretation of their findings in terms of compliance. A group of 48 subjects was instructed to simulate a response to an arm levitation suggestion. The suggestion was worded in one of four different way…

The Effects of Repression‐sensitization on a Brightness Scaling Measure of Perceptual Defence
The relationship between perceptual sensitivity and stimulus emotionality was investigated employing a methodology aimed to preclude the intervention of response variables. Forty‐six subjects estimated the relative brightness of pairs of physically identical light signals superimposed on subliminal words presented below the awareness threshold. Byrne's Repression‐Sensitization scale was used as a possible personality correlate. Results supported …
