Cue-elicited negative affect in impulsive smokers.

Impulsivity is associated with cigarette smoking, but the nature of this relationship and the mechanisms that maintain it are relatively unknown. The relationship has often been thought to reflect appetitive processes, but research suggests that an affective pathway exists as well. The present study tested the effect of impulsivity on affective responses to an environmental smoking cue. Adult smokers (N=62) were exposed to a neutral cue and a smoking cue in separate experimental sessions in a repeated-measures design. Mixed-effects regression analyses showed that larger postexposure increases in negative affect were associated with high scores on 2 facets of impulsivity: urgency, t(179)=6.16, p<.001, and sensation seeking, t(179)=4.75, p<.001. Heightened impulsivity was associated with lower levels of positive affect generally but not with positive affective responses to cue exposure. Findings provide support for the existence of a negative affective pathway linking impulsivity and cigarette smoking, and they suggest that this pathway may be specific to the urgency and sensation-seeking components of impulsivity.     

Individual Differences in Attitudes Relevant to Juror Decision Making: Development and Validation of the Pretrial Juror Attitude Questionnaire (PJAQ)1

This study involves scale development using theoretically derived items from previous measures and a lay consensual approach for generating new items. Confirmatory factor analysis was used to validate the emergent constructs assessing individual differences in attitudes of prospective jurors. Using case summaries, the Pretrial Juror Attitude Questionnaire (PJAQ) demonstrates superior predictive validity over commonly employed measures of pretrial bias. The PJAQ confirms the importance of theoretically derived constructs assessed by other scales and introduces new constructs to the jury decision‐making literature. The attitudes assessed by the PJAQ are conviction proneness, system confidence, cynicism toward the defense, racial bias, social justice, and innate criminality. Implications for assessing such attitudes and for better understanding the decision‐making process of jurors are discussed.     

A survey of the use of facilitated communication in community agencies serving persons with developmental disabilities

Service providers to individuals with developmental disabilities at seven North Dakota agencies were surveyed on their current and past use of facilitated communication (FC). Perceived validity and effectiveness of FC were also assessed. Seventeen percent of the 177 direct care and supervisory staff surveyed reported that they had never heard of FC, 36% were aware of but had never used FC, 28% had previously used FC, and 18% currently used the technique despite overwhelming experimental evidence that FC is not a valid means of communication for people with disabilities. The results indicated that respondents who had previously used FC, but did not do so currently, gave it the lowest ratings of validity, usefulness, and likability, while current users gave FC the highest ratings. Current users had the fewest years of experience in the field of developmental disabilities. The majority of current users said guardian approval should not be required prior to the use of FC, whereas the majority of past users and non-users said that guardian approval should be required. © 1998 John Wiley & Sons, Ltd.     

Forgive and Forget? Forgiveness,Personality, and Wellness Among Counselors‐in‐Training

Forgiveness as a method of addressing “wounds” has been linked to enduring aspects of personality and improved physical and mental health outcomes. The aim of this study was to understand the effects of forgiveness on counseling students’ overall wellness. Counseling students (N= 115) from 5 universities completed self‐report measures of forgiveness, wellness, and personality. Results indicate that, when personality factors are controlled, forgiveness contributes a significant proportion (10%) of the variance in wellness for counseling students. Implications for counselor training and counseling are discussed.     

The resonant dynamics of speech perception: interword integration and duration-dependent backward effects

How do listeners integrate temporally distributed phonemic information into coherent representations of syllables and words? For example, increasing the silence interval between the words "gray chip" may result in the percept "great chip," whereas increasing the duration of fricative noise in "chip" may alter the percept to "great ship" (B. H. Repp, A. M. Liberman, T. Eccardt, & D. Pesetsky, 1978). The ARTWORD neural model quantitatively simulates such context-sensitive speech data. In ARTWORD, sequentially stored phonemic items in working memory provide bottom-up input to unitized list chunks that group together sequences of items of variable length. The list chunks compete with each other. The winning groupings feed back to establish a resonance which temporarily boosts the activation levels of selected items and chunks, thereby creating an emergent conscious percept whose properties match such data.     

The acquisition of an appetite

Unlike older animals, weanling-age rats do not seek water to drink when they are dehydrated, despite the fact that a physiological sensitivity to dehydration is present very soon after birth. We demonstrate here that the appetitive behaviors needed to approach and obtain water become linked to dehydration only as a result of specific postnatal learning experience. Preventing early experience with dehydration retards the developmental emergence of dehydration-induced, water-oriented behavior in young rats. But a single pairing of water with dehydration can establish an appetitive response. These findings reveal a critical role of early learning in the development of goal-oriented behavior. Such a learning process is potentially characteristic of other behavioral systems, from the most basic appetites to complex motives.     

Preferences for involvement in medical decision making: comparing British and German views

Despite beneficial outcomes of patients' involvement in medical decision processes, it has been claimed that patients are generally not interested in medical decision making (MDM). Whereas current research focuses on actual MDM, this research explored the impact of nationality and perceptual processes of MDM. Preferences for involvement in decision making were examined in a sample of 204 German and 143 British university students. Hierarchical multiple regressions were employed to explore the link between socio-demographic information, individuals' perceived relationship with their GP, Health Locus of Control - Powerful Others, perceptions regarding the frequency and sufficiency of information provision and involvement in MDM, and individuals' preferred level of involvement and information. A significant amount of the variance in individuals preferences for involvement could be explained (Adjusted R2 = .59, p < .001). Independent t-test analyses showed that British and German perceptions of care differed significantly on a variety of different measures. Separate analyses for the German and British group highlighted cross-national differences in care and preferences for involvement. The study suggests that preferences to become involved might depend more on perceptual processes than actual involvement in decision making, and that communication and national health policy could play an important role.
