Paranormal belief, thinking style preference and susceptibility to confirmatory conjunction errors
Paranormal belief and errors of probabilistic reasoning
Measures of Bayesian Reasoning Performance on ‘Normal’ and ‘Natural’ Frequency Tasks
While the majority of similar studies examining Bayesian reasoning investigate how participants avoid common errors such as base-rate neglect, the current research also examines whether different formats (frequency and probability) lead to a difference in levels of absolute accuracy. In Study One, older (≥60 years) and younger (18 to 29 years) participants completed tasks in probability and normalized frequency formats. In Study 2, participants c…
How does the extraversion personality trait influence false recall with the Deese–Roediger–McDermott (DRM) paradigm
Age and probabilistic reasoning
Probabilistic reasoning plays an essential part in many aspects of our daily routine and it has been argued that as we grow older, the need to make judgements under uncertainty becomes increasingly important. Two studies were conducted to establish whether the propensity to commit probabilistic reasoning errors increased with age. Young (aged 16–24), middle aged (25–54), and older persons (55 years and above) were included. Study 1 revealed syste…
Evidence for executive deficits among users of MDMA (Ecstasy)
Random letter generation and computation span are tasks known to load on executive, prefrontal resources. Previous research suggests that Ecstasy users are impaired on random letter generation. The current study, employing a larger sample (44 current Ecstasy users, and 59 non‐Ecstasy users), together with more effective statistical controls for other drug use, failed to replicate previous findings. Ecstasy users were unimpaired on all measures of…
Judgments under uncertainty
Tversky and Kahneman's (1983) account of conjunctive probability judgment in terms of the representativeness heuristic is questioned. Instead, potential surprise (Shackle, 1969) is proposed as an important mechanism underlying subjective probability judgment. Study 1 reveals that, consistent with Shackle's theory, probabilities assigned to conjunctions are predominantly determined by the magnitude of the smaller component event probability. Also …
Working memory deficits in current and previous users of MDMA (‘ecstasy’)
Current and previous users of the drug MDMA (‘ecstasy’) were tested on measures of central executive functioning, information processing speed, and on self‐report measures of arousal and anxiety. The results were compared with those for a control group who did not use MDMA. Relative to the control group, both user groups were found to be impaired in some aspects of central executive functioning. Also, there were significant group differences on t…
Associative Learning and Short-Term Forgetting as a Function of Age, Perceptual Speed, and Central Executive Functioning
In a study of two components of associative learning, it was found that during acquisition older people were more likely to forget material on which they were previously correct, but only for associations which were not well learned. Older people also formed fewer correct associations in the course of the task. Differences in learners' perceptual speed were found to account for some of the age deficit in the number of learning attempts, but speed…
The conjunction fallacy
A study was conducted to evaluate the effects of training on the incidence of the conjunction fallacy. One group received training in the extension rule (normative), the other training which stressed that judgments should be based on similarity or representativeness (non‐normative). Participants receiving the former made fewer errors, those receiving the latter made more errors. However, multiple regression analysis showed that under both trainin…
