Relative frequency of attribute relevance and response times in visual search

Two experiments, one using a between-Ss and one a within-Ss design, showed that response latencies to single attribute probe stimuli were longer when the target stimulus embodied two attributes (form and color) rather than a single attribute. The magnitude of this "mixed attribute effect" was influenced by the probability of attribute relevance, but the "probability effect" was mostly due to a "repetition effect," such that latencies on trials involving repetitions of the same attribute were shorter than when the relevant attribute was shifted. Implications of these results are drawn for the issues of holistic vs attributized representation of the target stimulus and serial vs parallel search of a set of attributes. Although no class of models can be ruled out on the basis of these experiments, constraints can be imposed on the versions of each that are compatible with the data presented.     

Cue-type manipulation dissociates two types of task set inhibition: backward inhibition and competitor rule suppression

Backward inhibition (BI) reflects the suppression of a recently abandoned task set to allow for smooth transition to a new task even when the rules do not generate a response conflict. Competitor rule suppression (CRS) reflects the inhibition/suppression of irrelevant task rules when these rules generate a response conflict even if they have not recently been abandoned. We assessed whether BI and CRS are differentially affected by the difficulty in retrieving category-response mappings from memory. Retrieval demands were manipulated via the information provided by the task cues, which either indicated the relevant dimension (dimension cues; “color”) or the relevant dimension with its category-to-key mapping (mapping cues; “red green”, indicating that “red” and “green” go with the left/right responses, respectively). CRS was larger with dimension compared to mapping cues when cue-type varied between groups and was larger after trials involving dimension cues when cue-type varied on a trial-by-trial basis. In contrast, BI was not influenced by cue-type. These results suggest that task switching involve at least two distinct inhibitory processes, with CRS being related to the ease of retrieval of category-response mappings from memory.     

Using Implementation Intentions in Shopping Situations: How Arousal Can Help Shield Consumers Against Temptation

Previous research has suggested that individuals who repeatedly experience self‐regulatory failure in purchasing behaviour have trouble shielding themselves against temptations. Because shopping is often accompanied by increased arousal, we examined whether attending to affective arousal could help people keep their attention focused. Before participants completed a visual distraction task embedded in a shopping context, we (i) instructed them to formulate an implementation intention with affective arousal as the eliciting cue and concentrating on the task as the intention; (ii) instructed them to formulate the goal intention of concentrating on the task without mentioning an eliciting cue; or (iii) gave them no further instructions. During the task, we recorded eye movements to measure the time they looked at the target products. The findings suggest that implementation intentions with affective arousal as an eliciting cue enable consumers who repeatedly perceive self‐regulatory failure to focus their attention on their initial shopping goal.

Factors Influencing Level of Stress During the Nursing Home Decision Process

This investigation examined whether characteristics of elders and their caregivers and facets of the nursing home decision-making context were associated with recalled levels of stress during nursing home decision-making. Employing a conceptual framework based upon the literature on caregiver stress and nursing home decision-making, we considered a number of factors that might influence sponsors' stress as decisions were being made about nursing home placements. We examined data from telephone interviews with a sample of 142 sponsors (responsible parties) of first-time, recently admitted nursing home residents. Higher levels of reported stress were directly associated with more factors triggering the decision to admit, higher levels of competing demands, and limited time. Employment was indirectly related to higher stress through its impact on demands. Hospitalization and being the spouse or an adult child of the resident were indirectly related to stress because they were associated with limited available time. The results offer some insights into the types of individuals who may be vulnerable to higher levels of stress and the kinds of interventions that might avert high stress in the nursing home decision process.     

Deviations in the emergence of representations: a neuroconstructivist framework for analysing developmental disorders

A common way of studying developmental disorders is to adopt a static neuropsychological deficit approach, in which the brain is characterized in terms of a normal brain with some parts or ‘modules’ impaired. In this paper we outline a neuroconstructivist approach in which developmental disorders are viewed as alternative developmental trajectories in the emergence of representations within neural networks. As a concrete instantiation of the assumptions underlying this general approach, we present a number of simulations in an artificial neural network model. The representations that emerge under different architectural, input and developmental timing conditions are then analysed within a multi‐dimensional state space. We explore alternative developmental trajectories in these simulations, demonstrating how initial differences in the same parameter can lead to very different outcomes, and conversely how different starting states can sometimes result in similar end states (phenotypes). We conclude that the assumptions of the neuroconstructivist approach are likely to be more appropriate for analysing developmental deviations in complex dynamic neural networks, such as the human brain.     

On the Vicarious Humanity of Christ

In the recent literature there has been a spate of essays, articles and books discussing the question of whether Christ had a ‘fallen’ human nature. This article offers a new argument for the conclusion that Christ had a fallen but not sinful human nature that was ‘healed’ of its fallenness at the moment of assumption by the Word – what we shall call, the vicarious humanity of Christ view. This account concedes to the defender of Christ's ‘fallen’ humanity that his human nature is generated in a fallen state (and immediately cleansed of fallenness in the act of assumption). And it concedes to the defender of Christ's sinlessness the claim that Christ is without sin from the first moment of incarnation. This represents an important via media in the contemporary debate about this vexed christological topic.     

Peer-mediated social-skills training and generalization in group homes

A multiple baseline across subjects design was used to evaluate generalization effects of a peer-tutoring procedure to teach social skills for individuals with developmental disabilities. Three residents with poor social skills living in community-based group homes served as participants in this study. Generalization data were collected during four conditions: (i) baseline (ii) social-skills training by therapist (iii) social-skills training by peer-tutor, and (iv) follow-up. Results demonstrated that participants did not generalize trained social skills to untrained settings (i.e., living room of a group home and community bowling alley) until the first participant was trained as a peer-tutor to train two other participants. These results were maintained 6 months after training was withdrawn. © 1998 John Wiley & Sons, Ltd.     

Divorce mediation: the impact of mediation on the psychological well‐being of children and parents

This study evaluated levels of psychological distress experienced by children (aged 4–16) and parents at the beginning of and one month after mediation for child‐related disputes. In contrast to previous research, this study employed both child‐ and parent‐reports of child outcome. Mediation was associated with reductions in child‐reported, though not parent‐reported, child psychological distress and with reductions in parent‐reports of their own psychological distress. The negotiation of successful agreements in mediation was not related to improved psychological well‐being of family members. The difficulties encountered (i.e. small numbers, low response rate) render the results tentative. Implications of the findings for future research are discussed.
