Memory access: The effects of fact-oriented versus problem-oriented acquisition

This study examined the effects of similarity between the processing of acquisition and the processing of test materials on performance in a problem solving task. Previous work by Perfetto, Bransford, and Franks (1983) demonstrated that uninformed subjects’ failure to utilize relevant acquisition information in a later problem solving task is the result of a failure to spontaneously access such information. The present study demonstrated that spontaneous access can be enhanced when both acquisition and test materials are processed in a similar manner, that is, in a problem-oriented manner. Furthermore, the present findings indicate that the processing similarity leading to enhanced access is specific to particular acquisition and test items, rather than a general problem solving set induced at acquisition and the subsequent testing situation. Results are interpreted within a transfer-appropriate processing perspective.     

A comparison of the effects of child management and planned activities training in five parenting environments

This study compared the effects of two procedures designd to enhance the extratraining effects of behavioral parents training. Twenty parents of oppositianal children were randomly assign to either a child manangment training condition or a combined child management plus planned activity condition. A further 10 nonproblem children and their parents serve as a social validation group. Observation of both parents and children behavior were conducted in each of five home observation setting (breakfirst time, kindy (kindergarten) or school exit, a structured playtime, bathtime, and bedtime). Both training procedures result in change in both child oppositional and parents oversive behaviosr in all observation settings. In addition, desire positive parents behaviour also improve in all setting. Treatment effect were maintained in all setting at 3-month follow up. Composition between oppositional children following treatment and children in the social validation group showed that they each displayed similarly low lavels of oppositional behaviour in all settings. The inplecation of the results for faciliating generalised changes in behavioral parent training are discusssd.This study was supported by a grant from the National Health and Medical Research Council (NHMRC324 82 579049). We wish to thank all families, therapists, and observers who participated in the project.     

PSYCHOLOGY IN THE AUSTRALIAN CONTEXT*

Psychology formally entered the Australian arena via university departments of Philosophy, commencing last century and taking its initial direction largely from Britain. The previous pattern of development of Australian psychology was more distinctive than is its present state. Although the influences of Germany and the United States have supplemented that of the parent country, it is difficult to discern any locally blended colouration in the discipline or the profession as they now appear. Somewhat distanced from the universities, applied psychology has flourished especially in the public sector beginning with the initial close liaison formed between psychology and education in a developing colonial society. The public impact of research and practice is by no means as apparent as in the United States or Britain. After a burgeoning in the ‘sixties and early ‘seventies, the present state is one of limited growth concurrent with the general recession.     

Can genetic risk information enhance motivation for smoking cessation? An analogue study.

Protection motivation theory and the extended parallel processing model are used to predict the motivational impact of information regarding a genetic susceptibility to heart disease. One hundred ninety-eight smokers read 1 of 3 vignettes: gene positive, gene negative, or standard smoking risk information. Analyses examined whether the impact of type of risk information was moderated by smokers' self-efficacy (SE) levels. Key outcomes were intention to quit and intention to attend an information session about quitting. There were significant main effects of SE and of receiving gene-positive risk information on intentions to quit. There was a significant Risk x SE interaction on intentions to attend an information session. SE was not associated with intentions to attend the information session for smokers in the gene-positive group. Intentions to attend the session were negatively associated with SE for smokers in the lower risk groups. Implications for using genetic risk information to motivate smoking cessation are discussed.     

Goal-relevant situations facilitate memory of neutral faces

Emotional situations are typically better remembered than neutral situations, but the psychological conditions and brain mechanisms underlying this effect remain debated. Stimulus valence and affective arousal have been suggested to explain the major role of emotional stimuli in memory facilitation. However, neither valence nor arousal are sufficient affective dimensions to explain the effect of memory facilitation. Several studies showed that negative and positive details are better remembered than neutral details. However, other studies showed that neutral information encoded and coupled with arousal did not result in a memory advantage compared with neutral information not coupled with arousal. Therefore, we suggest that the fundamental affective dimension responsible for memory facilitation is goal relevance. To test this hypothesis at behavioral and neural levels, we conducted a functional magnetic resonance imaging study and used neutral faces embedded in goal-relevant or goal-irrelevant daily life situations. At the behavioral level, we found that neutral faces encountered in goal-relevant situations were better remembered than those encountered in goal-irrelevant situations. To explain this effect, we studied neural activations involved in goal-relevant processing at encoding and in subsequent neutral face recognition. At encoding, activation of emotional brain regions (anterior cingulate, ventral striatum, ventral tegmental area, and substantia nigra) was greater for processing of goal-relevant situations than for processing of goal-irrelevant situations. At the recognition phase, despite the presentation of neutral faces, brain activation involved in social processing (superior temporal sulcus) to successfully remember identities was greater for previously encountered faces in goal-relevant than in goal-irrelevant situations.     

How honest are the signals? A protocol for validating wearable sensors

There is growing interest among organizational researchers in tapping into alternative sources of data beyond self-reports to provide a new avenue for measuring behavioral constructs. Use of alternative data sources such as wearable sensors is necessary for developing theory and enhancing organizational practice. Although wearable sensors are now commercially available, the veracity of the data they capture is largely unknown and mostly based on manufacturers’ claims. The goal of this research is to test the validity and reliability of data captured by one such wearable badge (by Humanyze) in the context of structured meetings where all individuals wear a badge for the duration of the encounter. We developed a series of studies, each targeting a specific sensor of this badge that is relevant for structured meetings, and we make specific recommendations for badge data usage based on our validation results. We have incorporated the insights from our studies on a website that researchers can use to conduct validation tests for their badges, upload their data, and assess the validity of the data. We discuss this website in the corresponding studies.
