The biomotometer, an electronic device that simultaneously measures activity and provides auditory feedback to the subject, was used in combination with material reinforcers in two experiments attempting to modify activity level in children. In the first study the activity level of an 11-year-old highly active boy was decreased below mean baseline during conditioning in a classroom setting. His level of activity returned to baseline when feedback was withdrawn. In the second study, activity level of a 10-year-old hypoactive boy was increased over mean baseline level during conditioning in a free-play setting, and returned to slightly below baseline during five extinction trials. Results of these studies indicate that the biomotometer is a useful instrument for modification of activity level.  相似文献

Activity level of 13 boys (aged 9–13) from a day hospital program was measured using actometers in classroom, gym, woodshop, and group therapy settings. Ratings of Ss' activity were obtained from mothers using the Werry scale, and from six clinical staff familiar with the Ss using the Davids scale. It was predicted that activity ratings would have situationally specific relationships with actometermeasured activity level according to the rater's opportunities for observation. Comparisons between measures indicated that all clinical staff ratings correlated significantly with actometer activity in the classroom (r=.49 to r=.73), while mothers' ratings correlated significantly with actometer activity in gym (r=.67), and woodshop (r=.77), and with overall activity (r=.65), a combined measure derived from actometer scores in the four conditions tested. Five of six clinical staff raters showed significant interrater reliability (r=.58 to r=.83). Results are discussed in terms of their implications for solution of current problems in assessment of activity level and hyperactivity.  相似文献

This article examines associations among representations of physical, name, and category information by determining effects of category repetition on and following physical, name, and category match trials. Subjects decided whether two letters were from the same half of the alphabet. Category repetition effects were evidenced by faster ~nd more accurate responses when letters from the same half of the alphabet were used on successive trials. Although physical matches showed no effect of category repetition, name and category matches did. Trials following physical matches were less affected by category repetition than were trials following name or category matches. The results suggested that these category repetition effects were mediated by interletter associations: Reaction time increased with the alphabetic distance between preceding and current letters. However, these distance effects held only for forward (A → B) and not backward (B → A) alphabetic sequences, suggesting that the alphabetic representation is ordinal and unidirectional.  相似文献

The aim of this study was to examine the impact of end-of-life (EoL) circumstances on grief and internalizing symptoms among bereaved siblings. Bereaved families (N?=?88) were recruited from three sites 3–12 months (M?=?11.57, SD?=?3.48) after their child’s death from cancer. One sibling per family aged 8–17 years (M?=?12.41, SD?=?2.64) was randomly selected to participate. Families completed measures of siblings’ grief and internalizing symptoms, as well as a structured interview about circumstances surrounding the death. Mother and sibling reports of EoL circumstances were generally concordant, except there was a discrepancy between mothers and children about whether or not children expected their sibling’s death (t(75)?=?1.52, p?=?.018). Mother reports of sibling internalizing symptoms were above the normative mean (t(83)?=?4.44, p?≤?.001 (M?=?56.01?±?12.48), with 39% (n?=?33) in the borderline/clinical range. Sibling opportunity to say goodbye was associated with greater grief-related growth (t(79)?=?? 1.95, p?=?.05). Presence at the death and wishing they had done something differently were both associated with greater grief (t(80)?=?? 2.08, p?=?.04 and t(80)?=?? 2.24, p?=?.028, respectively) and grief-related growth (t(80)?=?? 2.01, p?=?.048 and t(80)?=?? 2.31, p?=?.024, respectively). However, findings were primarily unique to sibling report, with few mother-reported effects. The adjustment of bereaved siblings may be affected by certain modifiable circumstances surrounding the death of their brother or sister. A proportion of bereaved siblings had elevated internalizing symptoms irrespective of circumstances at EoL. Further work is needed to understand predictors of adjustment among bereaved siblings to provide better support and optimize their outcomes.

Why do people change in therapy? A preliminary study. This work represents the beginning of a new way to study the processes that can explain the therapeutic change. The method used is the observation and analysis of therapeutic sessions directly recorded and developed inside a behavioural approach. The category system tries to carry out a functional analysis of the therapist-client interaction which enables the identification of learning processes that work in clinical setting and explain success in therapy. Outcomes are provisional but show the utility of this initial trend of investigation to the comprehension of clinical phenomenon. Conclusions also emphasize the importance of associative learning processes on the therapeutic change.  相似文献

Recent studies confirm that dispositional pessimism is related with a worse state of physical health, in comparison with dispositional optimism . The efficacy of stress coping strategies has been considered as a mediating mechanism in this relationship. The aim of the present study is to analyze in a sample of university students (n = 200) the association between dispositional optimism/pessimism and different categories of self-reported somatic symptoms , and evaluate the possible mediation of the stress coping strategies in this relationship. The results indicate that: 1) pessimism is positively related with the report of physical symptoms, whereas optimism is negatively associated to somatic complaints; and 2) this relationship can be mainly explained by the differential utilization of the coping strategy denominated self-criticism (characteristic of pessimism).  相似文献
