The enhancement of psychological wellness: Challenges and opportunities

Developed the concept of psychological wellness and made the case that proportionally more resources should be directed to the pursuit of this goal. Five pathways to wellness are considered, implicating aspects of individual development and the impact of contexts, settings, and policies. The five pathways are: forming wholesome early attachments; acquiring age- and ability-appropriate competencies; engineering settings that promote adaptive outcomes; fostering empowerment; and acquiring skills needed to cope effectively with life stressors. Although these noncompeting pathways have differential salience at different ages and for different groups and life conditions, each is an essential element in any comprehensive social plan to advance wellness. Examples of effective programs are cited in all five areas, including recent comprehensive, long-term programs embodying multiple pathways to wellness. Some ideas in this paper were first presented in a talk at the W. T. Grant Foundation-sponsored conference on “Risk, Resiliency and Development,” Kiawah Island, S. Carolina, May 30, 1992.

A transfer of functions through derived arbitrary and nonarbitrary stimulus relations

During Experiments 1 and 2, subjects were trained in a series of related conditional discriminations in a matching-to-sample format (A1-B1, A1-C1 and A2-B2, A2-C2). A low-rate performance was then explicitly trained in the presence of B1, and a high-rate performance was explicitly trained in the presence of B2. The two types of schedule performance transferred to the C stimuli for all subjects in both experiments, in the absence of explicit reinforcement through equivalence (i.e., C1 = low rate and C2 = high rate). In Experiment 2, it was also shown that these discriminative functions transferred from the C1-C2 stimuli to two novel stimuli that were physically similar to the C stimuli (SC1 and SC2, respectively). For both these experiments, subjects demonstrated the predicted equivalence responding during matching-to-sample equivalence tests. In Experiments 3 and 4, the conditional discrimination training from the first two experiments was modified in that two further conditional discrimination tasks were trained (C1-D1 and C2-D2). However, for these tasks the D stimuli served only as positive comparisons, and ND1 and ND2 stimuli served as negative comparisons (i.e., C1 × ND1 and C2 × ND2). Subsequent to training, the negatively related stimuli (ND1 and ND2) did not become discriminative for the schedule performances explicitly trained in the presence of B1 and B2, respectively. Instead, the ND1 stimulus became discriminative for the schedule performance trained in the presence of B2, and ND2 became discriminative for the schedule performance trained in the presence of B1. All subjects from Experiment 4 showed that the novel stimulus SND1, which was physically similar to ND1, became discriminative for the same response pattern as that controlled by ND1. Similarly, SND2, which was physically similar to ND2, became discriminative for the same response pattern as that controlled by ND2. Subjects from both Experiments 3 and 4 also produced equivalence responding on matching-to-sample equivalence tests that corresponded perfectly to the derived performances shown on the transfer of discriminative control tests.     

Cross-modal transfer of conditioned suppression in rats: Effects of US intensity and extinction of the initial conditioning task

In conditioned suppression of water licking behavior by rats, we obtained data indicating general transfer of fear conditioning. A series of experiments resulted in two major findings. First, pairing of a neutral stimulus with a shock in the initial conditioning task facilitated acquisition of subsequent fear conditioning to another neutral stimulus, if the conditioned fear of the initial task was extinguished prior to the second task and if equally strong shocks were employed in both conditioning tasks. Second, omission of the extinction treatment or employment of weaker shocks in the initial task resulted in retardation, rather than facilitation, of the second conditioning task. An application to human clinical settings is discussed.     

小学生阅读迁移机制的初步研究--字词表征还是内容表征

探讨文章字词与内容在小学生篇章阅读迁移中的作用。结果发现,阅读水平和阅读条件均对阅读迁移效果有显著主效应。阅读水平低的被试的阅读准确性提高得更大;完全重复条件和词汇重复条件在阅读时间和准确性上都没有显著差异,完全重复条件下的阅读时间和准确性均比意义重复及无相关条件的阅读时间和准确性提高得更多;词汇重复条件下的阅读时间和准确性显著高于意义重复条件下的成绩;词汇相同的阅读准确性也显著高于无相关条件下的阅读准确性。据此,我们可以初步得出小学生的篇章阅读迁移主要依赖词汇表征,即词汇表征是小学生篇章阅读迁移的主要机制。

Properties of intermodal transfer after dual visuo- and auditory-motor adaptation

Previous work documented that sensorimotor adaptation transfers between sensory modalities: When subjects adapt with one arm to a visuomotor distortion while responding to visual targets, they also appear to be adapted when they are subsequently tested with auditory targets. Vice versa, when they adapt to an auditory-motor distortion while pointing to auditory targets, they appear to be adapted when they are subsequently tested with visual targets. Therefore, it was concluded that visuomotor as well as auditory-motor adaptation use the same adaptation mechanism. Furthermore, it has been proposed that sensory information from the trained modality is weighted larger than sensory information from an untrained one, because transfer between sensory modalities is incomplete. The present study tested these hypotheses for dual arm adaptation. One arm adapted to an auditory-motor distortion and the other either to an opposite directed auditory-motor or visuomotor distortion. We found that both arms adapted significantly. However, compared to reference data on single arm adaptation, adaptation in the dominant arm was reduced indicating interference from the non-dominant to the dominant arm. We further found that arm-specific aftereffects of adaptation, which reflect recalibration of sensorimotor transformation rules, were stronger or equally strong when targets were presented in the previously adapted compared to the non-adapted sensory modality, even when one arm adapted visually and the other auditorily. The findings are discussed with respect to a recently published schematic model on sensorimotor adaptation.     

The postural control can be optimized by the first movement initiation condition encountered when submitted to muscle fatigue

We investigated whether and how the movement initiation condition (IC) encountered during the early movements performed following focal muscle fatigue affects the postural control of discrete ballistic movements. For this purpose, subjects performed shoulder flexions in a standing posture at maximal velocity under two movement IC, i.e., in self-paced conditions and submitted to a Stroop-like task in which participants had to trigger fast shoulder flexions at the presentation of incongruent colors. Shoulder flexion kinematics, surface muscle activity of focal and postural muscles as well as center-of-pressure kinematics were recorded. The initial IC and the order in which subjects were submitted to these two conditions were varied within two separate experimental sessions. IC schedule was repeated before and after fatigue protocols involving shoulder flexors. The aim of this fatigue procedure was to affect acceleration-generating capacities of focal muscles. In such conditions, the postural muscle activity preceding and accompanying movement execution is expected to decrease. Following fatigue, when subjects initially moved in self-paced conditions, postural muscle activity decreased and scaled to the lower focal peak acceleration. This postural strategy then transferred to the Stroop-like task. In contrast, when subjects initially moved submitted to the Stroop-like task, postural muscle activity did not decrease and this transferred to self-paced movements. Regarding the center-of-pressure peak velocity, which is indicative of the efficiency of the postural actions generated in stabilizing posture, no difference appeared between the two sessions post-fatigue. This highlights an optimization of the postural actions when subjects first moved in self-paced conditions, smaller postural muscle activation levels resulting in similar postural consequences. In conclusion, the level of neuromuscular activity associated with the postural control is affected and can be optimized by the initial movement IC experienced post-fatigue. Beyond the fundamental contributions arising from these results, we point out potential applications for trainers and sports instructors.

Effects of self‐enhancement on agreement on personality profiles

Effects of self‐enhancement and socially desirable responding (SDR) on rater agreement for personality profiles were studied in 304 students. Dyads of participants described themselves and their peer on the Revised NEO Personality Inventory (NEO‐PI‐R) that measures 30 facets of personality. In addition, participants filled in six scales measuring self‐enhancement or SDR. Data analyses focussed on moderator and suppressor effects of SDR on the similarity between self‐reported and other reported NEO‐PI‐R profiles. Three kinds of profile agreement were distinguished: (a) normative agreement; (b) distinctive agreement and (c) profile normativeness, that is, how strongly a self‐reported personality profile resembled the average profile of all participants. There were no moderator or suppressor effects on distinctive agreement, but SDR predicted profile normativeness quite strongly. Copyright © 2009 John Wiley & Sons, Ltd.
