The Role of Worldviews in Predicting Support for Recreational Cannabis.

We studied the role of worldviews in the endorsement of proposals for the legalisation of recreational cannabis. Drawing on literature on generalised belief structures, we developed categorical measures for five worldviews drawing on commonalities in the typologies reviewed (Orthodox, Localised, Reward, Pragmatist, and Survivor). We proceeded to study the relative influence of worldviews in support of a range of items concerned with the legalisation of recreational cannabis amongst a randomly generated sample ( = 1000) in Malta.

Introspective Projection: Prototypical Representations of Policing in the Service of Rule of Law.

Mass protests that have taken place over the past decade in various Western democracies have called into question the role of police in society, as officers have employed measures to contain rallies protesting for or against various issues. A number of these protests have resorted to violent means, resisting the police or protesting directly against their role and methods. The present study sought to investigate the prototypical representations of the police that lay citizens use to forge or desist identification with police officers.

Developing a model of perceptions of security and insecurity in the context of crime.

The current study was carried out as part of the CITYCOP project exploring fear of crime, risk perception and feelings of security and insecurity. Participants ( = 272) from 11 European countries answered a questionnaire exploring measures of risk perception, fear of crime, anxiety, trust in police and related behaviours. A seven-factor structure is proposed incorporating 'Signs of Social and Physical Disorder', 'Trust in Police', 'Trait Anxiety', 'Collective Efficacy', 'Perceived Risk of Victimisation', 'Fear of Personal Harm' and 'Fear of Property Theft'.

Disaster preparedness and cultural factors: a comparative study in Romania and Malta.

This exploratory study investigates the relationships between the disaster preparedness of citizens and cultural factors in Romania and Malta. With regard to methodology, quantitative and qualitative data were collected during two Citizen Summits, which consisted of a real-time survey and focus group discussions. The results point to two specific cultural factors that may bridge this 'gap' and be operationalised to enhance people's readiness for a disaster event.

Perceptual similarity in autism.

People with autism have consistently been found to outperform controls on visuo-spatial tasks such as block design, embedded figures, and visual search tasks. Plaisted, O'Riordan, and others (Bonnel et al., 2003; O'Riordan & Plaisted, 2001; O'Riordan, Plaisted, Driver, & Baron-Cohen, 2001; Plaisted, O'Riordan, & Baron-Cohen, 1998a, 1998b) have suggested that these findings might be explained in terms of reduced perceptual similarity in autism, and that reduced perceptual similarity could also account for the difficulties that people with autism have in making generalizations to novel situations.

Strategic processes in false recognition memory.

In two experiments, the response signal technique (Reed, 1973) was combined with the DRM paradigm (e.g., McDermott & Roediger, 1998) to investigate the time course of false recognition memory--in particular, how this effect varies along the time course of generating a recognition judgment.

Adaptive changes of response criterion in recognition memory.

An experiment was conducted to investigate people's ability to vary a response criterion strategically, in a recognition memory task, as a function of the length of time given to process the test stimuli (from 100 to 1,500 msec). The experiment used the response signal procedure, in which the participants responded after a signal that came at a variable time delay from stimulus onset. The proportion of new versus old test items was varied systematically with the time of the response signal, with the proportion of new test items rising, falling, or staying constant at later signals.

Feature-sampling and random-walk models of individual-stimulus recognition.

Traditional process models of old-new recognition have not addressed differences in accuracy and response time between individual stimuli. Two new process models of recognition are presented and applied to response time and accuracy data from 3 old-new recognition experiments. The 1st model is derived from a feature-sampling account of the time course of categorization, whereas the 2nd model is a generalization of a random-walk model of categorization.

Perceptual processes in matching and recognition of complex pictures.

The role of perceptual feature sampling in speeded matching and recognition was explored in 4 experiments. Experiments 1-3 involved a perceptual matching task with pictures of various objects and scenes. In Experiments 2 and 3, same-different judgments were given under time pressure.
