Problematic and unhealthy personality characteristics have typically been the focus of researchers interested in the possible causes of substance use/abuse. Recent research has begun to identify differences between individuals based upon frequency of use, with indications that moderate users may have "healthier" characteristics than either abstainers or regular users. The present study was conducted in a rural setting and compared personality structure (based on the California Psychological Inventory) among three groups of college students: abstainers, experimenters, and regular users. The comparisons were conducted as a function of all illicit substance use (excluding alcohol) and for alcohol use only. Minimal support was obtained for the above hypothesis when comparing the three groups on illicit substance use. When comparing the three groups on alcohol use only, support for the theory was identified, with fewer differences found between the experimenters and the abstainers than between the experimenters and the regular users. It is suggested that rural use of psychoactive substances may be more limited to alcohol due to easier availability and less stigma. Data supporting the "healthier" personality structure of moderate users of alcohol would thus be more likely in rural settings even though such use would still be "risky" behavior given its illegality for individuals under age 21. The need for adaptations to current treatment approaches is suggested. 相似文献

The primary purpose of the study was to identify event-based prospective-memory tasks that provide sensitive and reliable tools for assessing effects of normal aging in prospective-memory performance. Four prospective-memory tasks were selected from the literature or were newly developed, with the tasks differing on various dimensions that, for theoretical reasons or based on previous evidence, might determine task sensitivity to age effects on prospective-memory performance: perceptual saliency of prospective target events, frequency of occurrence of prospective target events, complexity of prospective-memory instructions, and provision of feedback after prospective-memory errors. Two of the four tasks yielded large and robust age effects on prospective-memory performance. Correlational analyses suggested that these age effects on prospective-memory performance were mediated, at least in part, by a reduced ability of older adults to maintain prospective intentions in a highly activated state and not by age effects on basic mental speed alone. 相似文献

Two models of metaphor processing are contrasted. The structure-mapping model postulates an initially role-neutral alignment process, followed by directional projection of inferences. The attributive categorization model postulates role-specific processing throughout comprehension. To test between these models, the early stages of metaphor comprehension were probed using a technique based on S. Glucksberg, P. Gildea, and H. Bookin's (1982) finding that metaphorical meaning interferes with literal truthfulness judgments. In Experiment 1, interference effects did not differ between normal metaphors and metaphors with reversed terms, suggesting that initial processing is role-neutral. In Experiment 2, we again found no role dependence in interference effects, even for highly conventional metaphors. In Experiment 3, it was verified that (a) full comprehension is role-sensitive and (b) full comprehension reaction times (RTs) are far longer than interference RTs, buttressing the claim that interference is an early-stage effect. Overall, the results support the structure-mapping model of metaphor processing. 相似文献

Zusammenfassung Es war das Ziel der Untersuchung, ein System der Gefühlsqualitäten zu finden, das im Unterschied zu früheren Klassifikationsversuchen nicht auf der Anwendung formaler Kategorien oder anderer, gewissermaßen von außen an den Gegenstand herangetragener Gesichtspunkte beruhte, sondern aus den Erlebnisinhalten selbst hervorging.Nach verschiedenen Methoden wurden drei Versuche unternommen, in denen die Versuchspersonen auf Grund der Vergegenwärtigung des Erlebnisses Urteile über die Ähnlichkeit und über bestimmte Eigenschaften von Gefühlsqualitäten abzugeben hatten.Aus den Ergebnissen aller drei Versuche konnten Ordnungssysteme der verwendeten Gefühlsqualitäten gebildet werden. Trotz der Verschiedenheit der angewendeten Methoden besteht zwischen den drei Systemen in den vergleichbaren Punkten eine nahezu vollkommene Übereinstimmung.Die Gesamtheit der Gefühlsqualitäten ordnet sich nach dem Resultat dieser Untersuchung in drei Dimensionen an, denen die Bezeichnungen Angenehm—Unangenehm, Unterwerfung—Überhebung und Grad der Motivierung gegeben wurden.Nach einigen Betrachtungen über die der Beurteilung von Gefühlsqualitäten zugrunde liegenden subjektiven Prozesse werden methodische Folgerungen gezogen, die besagen, daß die Voraussetzungen für die Untersuchung der Gefühle weit günstiger sind, als dies nach der vorherrschenden Meinung der Fall ist. Schließlich wird die Anwendungsmöglichkeit der Resultate auf einige Fragestellungen der Gefühlsforschung an Hand von Beispielen erörtert. 相似文献

To investigate whether learning to discriminate between visual compound stimuli depends on decomposing them into constituting features, hens were first trained to discriminate four features (red, green, horizontal, vertical) from two dimensions (colour, line orientation). After acquisition, hens were trained with compound stimuli made up from these dimensions in two ways: a separable (line on a coloured background) stimulus and an integral one (coloured line). This compound training included a reversal of reinforcement of only one of the two dimensions (half-reversal). After having achieved the compound stimulus discrimination, a second dimensional training identical to the first was performed. Finally, in the second compound training the other dimension was reversed. Two major results were found: (1) an interaction between the dimension reversed and the type of compound stimulus: in compound training with colour reversal, separable compound stimuli were discriminated worse than integral compounds and vice versa in compound training with line orientation reversed. (2) Performance in the second compound training was worse than in the first one. The first result points to a similar mode of processing for separable and integral compounds, whereas the second result shows that the whole stimulus is psychologically superior to its constituting features. Experiment 2 repeated experiment 1 using line orientation stimuli of reversed line and background brightness. Nevertheless, the results were similar to experiment 1. Results are discussed in the framework of a configural exemplar theory of discrimination that assumes the representation of the whole stimulus situation combined with transfer based on a measure of overall similarity. 相似文献

This article reports on the feasibility of using interactive voice response (IVR) technology to obtain daily reports of attitudes
toward alcohol and tobacco use among children 9–13 years of age. Two studies were conducted. The first was an investigation
of the use of IVR technology to obtain daily data from a sample of primary school children over a period of 8 weeks. The second
was an extension of the research to a large sample of primary and secondary school children in urban and rural areas who provided
daily data over a 4-week period. Retention and compliance rates comparable to those obtained with adults were evident in both
studies, supporting the feasibility of this technology with children. The results are discussed in relation to the benefits
of this methodology for health research, particularly for studies of sensitive topics conducted with children and adolescents. 相似文献
