A beverage-specific measure of expectancies for malt liquor: development and initial testing

Malt liquor (ML) is a unique, high alcohol content beverage marketed to encourage heavy drinking. We developed the Malt Liquor Expectancy Questionnaire (MLEQ), a beverage-specific measure of alcohol expectancies, and examined its association with typical weekly ML use, typical weekly alcohol use, and alcohol problems. Forty positive and 40 negative expectancy items were administered to a sample of 639 young adults who regularly consumed ML. Exploratory and confirmatory factor analyses led to the development of the 30-item MLEQ. The MLEQ consists of two positive (i.e., Social Facilitation and Enjoyment, Enhanced Sexuality) and two negative factors (i.e., Aggression and Negative Consequences; Impairment and Physical Symptoms) that possess good internal consistency, test-retest reliability, and convergent validity. The psychometrically sound MLEQ contributes to the limited research on beverage-specific expectancies and heavy drinking.     

Mechanisms underlying skilled anticipation and recognition in a dynamic and temporally constrained domain

We examined the mechanisms underlying skilled anticipation and recognition in a dynamic, interactive, and temporally constrained domain. Skilled and less-skilled participants viewed dynamic film stimuli, anticipated event outcome, and provided immediate retrospective verbal reports. Previously viewed and novel sequences were then presented in film or point-light display format. Participants made recognition judgements and again gave retrospective verbal reports on their thought processes. Skilled participants demonstrated superior anticipation accuracy and were more sensitive in distinguishing previously seen from novel stimuli than less-skilled participants. Skilled participants utilised more complex memory representations than less-skilled individuals, as indicated by references in their retrospective reports to more evaluation and prediction statements. The representations activated during anticipation were more complex than those for recognition judgements in both groups. Findings are discussed with reference to long-term working memory theory.     

Contrasting effects of feature-based statistics on the categorisation and basic-level identification of visual objects

Conceptual representations are at the heart of our mental lives, involved in every aspect of cognitive functioning. Despite their centrality, a long-standing debate persists as to how the meanings of concepts are represented and processed. Many accounts agree that the meanings of concrete concepts are represented by their individual features, but disagree about the importance of different feature-based variables: some views stress the importance of the information carried by distinctive features in conceptual processing, others the features which are shared over many concepts, and still others the extent to which features co-occur. We suggest that previously disparate theoretical positions and experimental findings can be unified by an account which claims that task demands determine how concepts are processed in addition to the effects of feature distinctiveness and co-occurrence. We tested these predictions in a basic-level naming task which relies on distinctive feature information (Experiment 1) and a domain decision task which relies on shared feature information (Experiment 2). Both used large-scale regression designs with the same visual objects, and mixed-effects models incorporating participant, session, stimulus-related and feature statistic variables to model the performance. We found that concepts with relatively more distinctive and more highly correlated distinctive relative to shared features facilitated basic-level naming latencies, while concepts with relatively more shared and more highly correlated shared relative to distinctive features speeded domain decisions. These findings demonstrate that the feature statistics of distinctiveness (shared vs. distinctive) and correlational strength, as well as the task demands, determine how concept meaning is processed in the conceptual system.

Real-time comprehension processes in agrammatism: A case study

The ability of an agrammatic patient to construct structural syntactic and interpretative representations on-line was tested in two experiments. The first focused on global representations spanning an entire utterance, while the second examined lexical syntactic and semantic constraints on verb-argument relations. An off-line version of the second experiment was also carried out. There were two major findings. First, the patient could construct a semantic, but not syntactic, representation of an utterance. Second, he was much more dependent than normal upon pragmatic information. These results are discussed with respect to current claims about the nature of agrammatic comprehension deficits.     

Inattentive and noninattentive ADHD children: Do they constitute a unitary group?

Teacher-rated ADHD and normal control children were administered a continuous performance test (CPT), and were then further subdivided based upon the presence or absence of objectively assessed attentional deficits. In addition, children were assessed using several measures of cognitive and behavioral functioning. Attentional deficits were signficantly more prevalent among the ADHD group, but about half of the ADHD children showed no evidence of objectively assessed attentional dysfunction. Further group analyses indicated that ADHD children with objectively assessed attentional dysfunction appeared cognitively impaired, while ADHD children without objective evidence of attentional dysfunction had more conduct problems. CPT inattention was not related to the presence of cognitive impairments or conduct problems in the control group. These data must be considered preliminary because teacher ratings were the only source of diagnosis and a single measure of inattention was used. However, they suggest that two subtypes of ADHD children can be identified, one characterized by inattention and learning problems, and the other by conduct problems.The authors gratefully acknowledge the assistance of Sister Hildegard Kogler and the St. Francis DeSales School, and the parents and children who participated in this study.     

Sexual behaviour,condom use and prediction in attenders at sexually transmitted disease clinics—implications for counselling

A cohort of 260 clinic attenders completed an inventory to examine sexual behaviour, condom use and appraisal and to determine whether situational factors in their last sexual encounters were predictive of condom use. Response to health education compaigns promoting condoms in the light of HIV were also examined. It was found that risk exposure was consistently high. A subsample induldged in anal intercourse, which was unprotected in over two-thirds of instances. Condom uptake was varied Difficulties with condoms were widespread and fell into physical and psychological categories. The only predictor of condom use was the desire for unprotected sex. This data seems to indicate that sex is not a drive out of conscious control, but that individuals weigh up costs and benefits which may be marginally influenced by some situational variables such as alcohol. This has profound implications for counselling which can be aimed at addressing the misconceptions and beliefs that some individuals hold. Such misconceptions may result in risky behaviour which may potentially expose them to HIV. Such understanding is an important prerequisite for effective interventions. Differences between responses for heterosexual and homosexual men and women were examined.     

A comparison of UFO and near-death experiences as vehicles for the evolution of human consciousness

This study compares unidentified flying object experiencers (UFOErs) with near-death experiencers (NDErs) in regard to changes in attitudes toward self, others, and life in general, toward religious or spiritual orientation, and toward psychic abilities and beliefs. Kenneth Ring's questionnaires administered to NDErs (1984) were given in this study to 93 persons whose UFOE included either a light experience, an object experience, or a close encounter. The author concludes that the UFOE, like the NDE, provides impetus toward spiritual growth, but neither as consistently nor as strongly.This paper was derived in part from her M.A. thesis submitted to John F. Kennedy University.     

Infants' intermodal perception of two levels of temporal structure in natural events

Infants' intermodal perception of two levels of temporal structure uniting the visual and acoustic stimulation from natural, complex events was investigated in four experiments. Films depicting a single object (single, large marble) and a compound object (group of smaller marbles) colliding against a surface in an erratic pattern were presented to infants between 3 and months of age using an intermodal preference and search method. These stimulus events portrayed two levels of invariant temporal structure: (a) temporal synchrony united the sights and sounds of object impact, and (b) temporal microstructure, the internal temporal structure of each impact sound and motion, specified the composition of the object (single vs. compound). Experiment 1 demonstrated that by 6 months infants detected a relation between the audible and visible stimulation from these events when both levels of invariant temporal structure guided their intermodal exploration. Experiment 2 revealed that by 6 months infants detected the bimodal temporal microstructure specifying object composition. They looked predominantly to the film whose natural soundtrack was played even though the motions of objects in both films were synchronized with the soundtrack. Experiment 3 assessed infants' sensitivity to temporal synchrony relations. Two films depicting objects of the same composition were presented while the motions of only one of them was synchronized with the appropriate soundtrack. Both 6-month-olds showed evidence of detecting temporal synchrony relations under some conditions. Experiment 4 examined how temporal synchrony and temporal microstructure interact in directing intermodal exploration. The natural soundtrack to one of the objects was played out-of-synchrony with the motions of both. In contrast with the results of Experiment 2, infants at 6 months showed no evidence of detecting a relationship between the film and its appropriate soundtrack. This suggests that the temporal asynchrony disrupted their detection of the temporal microstructure specifying object composition. Results of these studies support on invariant-detection view of the development of intermodal perception.
