Processing ordinality and quantity: ERP evidence of separate mechanisms

We report an event-related potential (ERP) experiment of ordinal processing exploring the relationship between ordinal and numerical information.     

Women Inmate Substance Abusers’ Reactivity to Visual Alcohol, Cigarette, Marijuana, and Crack-Cocaine Cues: Approach and Avoidance as Separate Dimensions of Reactivity

Despite the growing recognition for multidimensional assessments of cue-elicited craving, few studies have attempted to measure multiple response domains associated with craving. The present study evaluated the Ambivalence Model of Craving (Breiner et al. Alcohol Research and Health 23:197–206, 1999; Stritzke et al. 2007) using a unique cue reactivity methodology designed to capture both the desire to use (approach inclination) and desire to not consume (avoidance inclination) in a clinical sample of incarcerated female substance abusers. Participants were 155 incarcerated women who were participating in or waiting to begin participation in a nine-month drug treatment program. Results indicated that all four substance cue-types (alcohol, cigarette, marijuana, and crack cocaine) had good reliability and showed high specificity. Also, the validity of measuring approach and avoidance as separate dimensions was supported, as demonstrated by meaningful clinical distinctions between groups evincing different reactivity patterns and incremental prediction of avoidance inclinations on measures of stages of change readiness. Taken together, results continue to highlight the importance of measuring both approach and avoidance inclinations in the study of cue-elicited craving.     

Work Meaning Patterns in Early Career

Abstract

Work meaning patterns combine dimensions such as work centrality, expressive versus economic work goals, and entitlement versus obligation societal norms into a holistic picture of the evolution over time of the meaning of work. Data from a longitudinal study in eight countries are used to establish major work meaning patterns and to study their stability during early career paths. Further, some potential determinants of these work meaning patterns are analysed and their consequences for later careers are considered. Statistical analyses include: cluster analysis, multiple discriminant analysis, analysis of covariance combined with multiple classification analysis, analysis of variance, and chi-square analysis. Five cross-national work meaning patterns are identified for machine operators in their third year in the labour market. One-third of the sample had remained in the same work meaning pattern for 2 years, while two-thirds had changed their work pattern. Respondents' age, country, prior work environment, and prior work socialization behaviours and outcomes have an impact on work meanings held 2 years later. In addition the respondent's work meaning pattern allows subsequent career enhancing strategies and effort expenditure at the job to be predicted.     

Driving experience, attentional focusing, and the recall of recently inspected events

How does a driver’s perception of roadway events change with experience? A laboratory study addressed this question by comparing novice and experienced drivers as they watched video recordings taken from a moving vehicle. While watching the recordings, the drivers had their eye movements monitored. When the recording was paused, memory for immediately prior events was tested, and recall performance related to what the viewer had been inspecting. The recordings were taken from a vehicle as it travelled along a series of roads, and questions were asked about other road users and about roadway features. The experiment asked about the relationship between driving experience and attentional capture, and about the recall of events recently seen. What attracted attention were objects of central interest such as other road users appearing close to the camera, and moving objects. When the memory test was administered immediately after a hazardous event had occurred, such as a pedestrian stepping into the path of the camera vehicle, then there was evidence of attentional focussing and reduced availability of details about incidental objects. Recall performance generally reflected the pattern of eye fixations, but viewers did not always recall details about fixated objects, and were sometimes able to recall information about objects that were not fixated. Experienced drivers recalled more of the incidental events than the novices, but they were similar in their recall of central events. This supports the association between driving experience and the extent of the effective perceptual field.     

Exploring the edges: boundaries and breaks

In this article, we examine conceptual and practical issues pertaining to relationship boundaries within the helping profession. Although our focus is primarily on relationships between mental health professionals and clients, there are considerable implications for a new approach to ethically structuring and understanding the construct of "required distance" in many human-interactive professions, such as teaching, religious leadership, public administration, and others. We define the concept of boundary as applied to human relationships, provide examples of boundary breaks, and raise questions regarding how to evaluate the significance and morality issues raised by specific boundary breaks. Questions and dilemmas are presented regarding boundary setting and accidental or deliberate boundary breaking. Representative dangers present in boundary breaks are identified, and examples are provided. Possible beneficial outcomes are also discussed. Finally, a suggested protocol for assessing a proposed boundary break is provided, much of which is drawn from the work and thinking of Laura Brown, applied more generally in this article, with additions from our perspectives.
