Do Sequential Lineups Impair Underlying Discriminability?, Matthew Kaesler, John C. Dunn, Keith Ransom, Carolyn Semmler

Research outputs 2014 to 2021

© 2020, The Author(s). Debate regarding the best way to test and measure eyewitness memory has dominated the eyewitness literature for more than 30 years. We argue that resolution of this debate requires the development and application of appropriate measurement models. In this study we developed models of simultaneous and sequential lineup presentations and used these to compare these procedures in terms of underlying discriminability and response bias, thereby testing a key prediction of diagnostic feature detection theory, that underlying discriminability should be greater for simultaneous than for stopping-rule sequential lineups. We fit the models to the corpus of studies …

Trajectories Of Quality Of Life, Life Satisfaction, And Psychological Adjustment After Prostate Cancer, Suzanne K. Chambers, Shu K. Ng, Peter C. Baad, Joanne F. Aitken, Melissa K. Hyde

Research outputs 2014 to 2021

Background

To describe trajectories of health-related quality of life (QoL), life satisfaction, and psychological adjustment for men with prostate cancer over the medium to long term and identify predictors of poorer outcomes using growth mixture models.

Methods

One-thousand sixty-four (82.4 % response) men diagnosed with prostate cancer were recruited close to diagnosis and assessed over a 72-month (6-year) period with self-report assessment of health-related QoL, life satisfaction, cancer-related distress, and prostate specific antigen anxiety. Urinary, bowel, and sexual function were also assessed using validated questionnaires.

Results

Poorer physical QOL was predicted by older age, lower education, lower income, comorbidities, and …

Answering Research Questions Without Calculating The Mean, Guillermo J. Campitelli

Research outputs 2014 to 2021

In an important theoretical article Speelman and McGann (2013) indicated that psychological researchers tend to use statistical procedures that involve calculating the mean of a variable in an uncritical manner. A typical procedure in psychological research consists of calculating the mean of some dependent variable in two or more samples and to present those means as summaries of the samples. The next step is to use some statistical technique (e.g., t -test, ANOVA) in order to be able to determine the probability of finding the observed differences between means in those samples given that the difference between the means of …

Attaining Automaticity In The Visual Numerosity Task Is Not Automatic, Craig P. Speelman, Katrina L. Muller-Townsend

Research outputs 2014 to 2021

This experiment is a replication of experiments reported by Lassaline and Logan (1993) using the visual numerosity task. The aim was to replicate the transition from controlled to automatic processing reported by Lassaline and Logan (1993), and to examine the extent to which this result, reported with average group results, can be observed in the results of individuals within a group. The group results in this experiment did replicate those reported by Lassaline and Logan (1993) ; however, one half of the sample did not attain automaticity with the task, and one-third did not exhibit a transition from controlled to …

Editorial: Neural Implementation Of Expertise, Merim Bilalic, Robert Langner, Guillermo J. Campitelli, Luca Turella, Wolfgang Grodd

Research outputs 2014 to 2021

How the brain enables humans to reach an outstanding level of performance typical of expertise is of great interest to cognitive neuroscience, as demonstrated by the number and diversity of the articles in this Research Topic (RT). The RT presents a collection of 23 articles written by 80 authors on traditional expertise topics such as sport, board games, and music, but also on the expertise aspects of everyday skills, such as language and the perception of faces and objects. Just as the topics in the RT are diverse, so are the neuroimaging techniques employed and the article formats. Here we …

Memory Behaviour Requires Knowledge Structures, Not Memory Stores, Guillermo J. Campitelli

Research outputs 2014 to 2021

Since the inception of cognitive psychology dominant theories of memory behavior have used the storage metaphor. In the multi-store models (e.g., Broadbent, 1958; Atkinson and Shiffrin, 1968; Baddeley and Hitch, 1974) the memory system comprises one or more short-term memory (STM) stores and a long-term memory (LTM) store. These stores are places where information is located for varying periods of time (i.e., seconds in the STM stores, and minutes to lifetime in the LTM store) and they have varying capacity limits: large for the LTM store, very limited for the STM store—4 to 7 items, see Miller (1956), Broadbent (1958), …
