Pathological gambling and suicidality: an analysis of severity and lethality

Pathological gambling represents a major public health issue. Risk factors for suicide such as major depression, substance abuse, marital breakdown, unemployment, financial crises, and legal difficulties are commonly found in populations of pathological gamblers. The objective of this study was to systematically investigate the nature of suicidal behavior among treatment-seeking pathological gamblers and its relationship to gambling characteristics and depression. Indices of suicidality were assessed in a sample of 85 treatment-seeking diagnosed pathological gamblers. High rates of suicidal ideation, suicidal plans, and attempts were found; however, no clear relationship was observed between suicidality and indices of gambling behavior. Depression rather than gambling specific characteristics, marital difficulties, or the presence of illegal behaviors appear to be related to the risk of suicidality.     

Spatial and nonspatial escape strategies in the Barnes maze

The Barnes maze is a spatial memory task that requires subjects to learn the position of a hole that can be used to escape the brightly lit, open surface of the maze. Two experiments assessed the relative importance of spatial (extra-maze) versus proximal visible cues in solving the maze. In Experiment 1, four groups of mice were trained either with or without a discrete visible cue marking the location of the escape hole, which was either in a fixed or variable location across trials. In Experiment 2, all mice were trained with the discrete visible cue marking the target hole location. Two groups were identical to the cued-target groups from Experiment 1, with either fixed or variable escape locations. For these mice, the discrete cue either was the sole predictor of the target location or was perfectly confounded with the spatial extra-maze cues. The third group also used a cued variable target, but a curtain was drawn around the maze to prevent the use of spatial cues to guide navigation. Probe trials with all escape holes blocked were conducted to dissociate the use of spatial and discrete proximal cues. We conclude that the Barnes maze can be solved efficiently using spatial, visual cue, or serial-search strategies. However, mice showed a strong preference for using the distal room cues, even when a discrete visible cue clearly marked the escape location. Importantly, these data show that the cued-target control version of the Barnes maze as typically conducted does not dissociate spatial from nonspatial abilities.     

Memory on the beach: an Australian memory (and hypnosis) laboratory

The memory (and hypnosis) lab at the University of New South Wales investigates a broad range of memory topics. We try to find innovative methods from cognitive and clinical psychology to address theoretical and empirical questions about memory. We aso use hypnosis as one major methodological tool in our investigations of memory (as well as other cognitive processes). In this paper, we review the projects currently underway in our memory (and hypnosis) lab.     

Categorical perception of familiar objects

We report three experiments where the categorical perception of familiar, three-dimensional objects was investigated. A continuum of shape change between 15 pairs of objects was created and the images along the continuum were used as stimuli. In Experiment 1 participants were first required to discriminate pairs of images of objects that lay along the shape continuum. Then participants were asked to classify each morph-image into one of two pre-specified classes. We found evidence for categorical perception in some but not all of our object pairs. In Experiment 2 we varied the viewpoint of the objects in the discrimination task and found that effects of categorical perception generalized across changes in view. In Experiment 3 similarity ratings for each object pair were collected. These similarity scores correlated with the degree of perceptual categorization found for the object pairs. Our findings suggest that some familiar objects are perceived categorically and that categorical perception is closely tied to inter-object perceptual similarity.     

The subjects as a simple random effect fallacy: subject variability and morphological family effects in the mental lexicon

This is a methodological study addressing the appropriateness of standard by-subject and by-item averaging procedures for the analysis of repeated-measures designs. By means of a reanalysis of published data (Schreuder & Baayen, 1997), using random regression models, we present a proof of existence of systematic variability between participants that is ignored in the standard psycholinguistic analytical procedures. By applying linear mixed effects modeling (Pinheiro & Bates, 2000), we call attention to the potential lack of power of the by-subject and by-item analyses, which in this case study fail to reveal the coexistence of a facilitatory family size effect and an inhibitory family frequency effect in visual and auditory lexical processing.     

Accounting for Violations of the Convict Code

Research over the past several decades shows that those who act in ways inconsistent with desired identities often account for (i.e., excuse or justify) their actions to save face and maintain social identities. While the bulk of research on the use of accounts examines how people make sense of behaviors that go against conventional values, recent research suggests that those who do not adhere to subcultural norms engage in similar talk. The current study builds on the sociology of accounts by exploring whether inmates articulate a convict code; whether they provide accounts for code violations that are comparable to those given by active offenders; and whether incarceration shapes inmates’ use of these accounts. Interviews with 40 inmates residing in a maximum security prison suggest that they rely on linguistic devices to align their actions with subcultural beliefs and that the prison environment structures the pattern of these accounts.     

A Dual Process Model of Attitudes towards Immigration: Person × Residential Area Effects in a National Sample

This research took a person × situation approach to predicting prejudice by looking at how social worldviews interact with real‐world environmental factors to predict how people respond to immigrants within their local area. Taking a Dual Process Motivational approach, we hypothesized that a higher proportion of immigrants in the local community would be associated with negative attitudes toward immigration for respondents high in dangerous world beliefs. Conversely, we hypothesized that living in a highly affluent (as opposed to socioeconomically deprived) community would be associated with negative attitudes toward immigration for respondents high in competitive world beliefs. Both hypotheses were supported using regional information derived from national census data combined with representative survey data from a large telephone sample conducted in New Zealand (N = 6,489). These findings support the proposition that individual differences interact with specific features of the environment to predict people's levels of prejudice in distinct ways.
