An analysis of timeout and response cost in a programmed environment

A group of mildly retarded adolescents with high rates of antisocial behavior was exposed to two parameters of timeout and response cost within the context of a programmed environment. For five of the six subjects, the two higher values (30 tokens response cost or 30 min timeout) were significantly more suppressive than the lower values (five tokens or 5 min). For the one remaining subject, there was a strong relationship in the opposite direction. Also, the timeout and response cost of higher value became increasingly more suppressive over time, whereas those of lower value did not. There were few appreciable differences between the timeout and response cost of similar magnitude. A discussion of these results is presented in support of the notion that the functional aversiveness of timeouts (and response costs) appears to be critically dependent upon interactions with the environmental conditions in which they are implemented and the reinforcement histories of the subjects.     

Divorcing mothers and social support: Testing the specificity of buffering effects

The circumstances under which social support buffers the negative effects of stress have been a subject of much research. The hypothesis that social support is effective only when it matches the needs elicited by particular stressors was studied in a sample of divorcing mothers. Predictions were made regarding which types of support (Parenting, Emotional, and Tangible) would buffer the effects of Parenting, Social, and Tangible stress on depressive symptoms and on general psychological distress of divorcing mothers. Results did not support the specificity of social support buffering effects, though the stress and support scales often showed direct relationships to criterion measures. Implications were discussed for the assessment of support with multiple models, for future research designs, and for planning prevention programs to meet the needs of divorcing mothers.     

Positive and negative social ties among older adults: Measurement models and the prediction of psychological distress and well-being

The factor structure of positive and negative social ties was studied among 246 older adults who were either recently physically disabled, recently conjugally bereaved, or matched controls. Covariance structure analyses were carried out on a network measure to determine whether positive and negative social ties represent independent domains of social experience, and to assess the degree to which their structure is invariant across groups undergoing major loss transitions. Positive and negative social ties were found to be independent and there was substantial similarity in their factor structure across the three groups. Hierarchical regression analyses revealed that, whereas positive social ties were related to psychological well-being, negative social ties were predictive of both psychological well-being and distress. These results demonstrate the importance of assessing both positive and negative ties in explaining the psychological adjustment of older adults.     

The Evolution of Social Ethics: Using Economic History to Understand Economic Ethics

In the development of Roman Catholic social thought from the teachings of the scholastics to the modern social encyclicals, changes in normative economics reflect the transformation of an economic terrain from its feudal roots to the modern industrial economy. The preeminence accorded by the modern market to the allocative over the distributive function of price broke the convenient convergence of commutative and distributive justice in scholastic just price theory. Furthermore, the loss of custom, law, and usage in defining the boundaries of economic behavior led to a depersonalization of economic relationships that had previously provided effective informal means of protecting individual well-being. Hence, recent economic ethics has had to look for nonprice, nonmarket mechanisms for distributive justice. This is reflected, for example, in the shift in attitude from the medieval antipathy toward unions to the contemporary defense of organized labor on moral grounds.     

Signal-centered action patterns of dogs in appetitive classical conditioning

The movements of five unrestrained dogs were monitored during discriminative Pavlovian conditioning. An auditory-visual stimulus from one source (CS+) was followed by meat morsels (US); the same stimulus from another source (CS?) was not. Sources were equidistant from the site of US delivery. Before each trial, animals were required to position themselves at a starting location equidistant from both sources and removed from the US site. The stable behavior pattern in most subjects included approach to and contact or near contact with CS+, followed by approach to the US site. Dogs showed individually distinctive action patterns to CS+, in some cases suggestive of soliciting, in another of sight-pointing. Similar actions were not evoked by CS?. In postacquisition tests, patterns were generally unaffected by increased deprivation or by relocating the starting position next to the US site. The auditory component of CS+ was more effective than the visual. With a response-contingent procedure animals were successfully trained to approach the US site directly, although many trials, and in one case a special procedure, were required. It was proposed that the experimental signaling arrangement mimics a natural signaling sequence and induces appetitive behavior to the CS that corresponds to the behavior induced by certain natural signals of the US.     

The transactional model of early home intervention

This article describes a developmental model for early home intervention and treatment of environmentally and biologically at-risk infants and their parents: The Transactional Model of Home Intervention. The model identifies the development of both infants and parents as targets of intervention and considers their ongoing interactions or transactions within the family context as the vehicle of intervention. The child and his physical/social environment are conceptualized as actively influencing one another in their reciprocal transactions. An early intervention program based on this transactional model is described. The intervention is tailored to suit the needs of both child and parents and, more generally, the needs of the family. The intervention process involves a problem-solving model of education by which parents acquire cognitive strategies that will enable them to assess the needs of their child and to design a program to fulfill these needs.     

Do Internet‐Based Support Interventions Change Perceptions of Social Support?: An Experimental Trial of Approaches for Supporting Diabetes Self‐Management

Internet-based support groups are a rapidly growing segment of mutual aid programs for individuals with chronic illnesses and other challenges. Previous studies have informed us about the content of online exchanges between support group members, but we know little about the ability of these interventions to change participants' perceptions of support. A randomized trial of 160 adult Type 2 diabetes patients provided novice Internet users with computers and Internet access to 1 of 4 conditions: (a) diabetes information only, (b) a personal self-management coach, (c) a social support intervention, or (d) a personal self-management coach and the support intervention. After 3 months, individuals in the 2 support conditions reported significant increases in support on a diabetes-specific support measure and a general support scale. Participants' age was significantly related to change in social support, but intervention effects were still significant after accounting for this relationship. This report is a critical first step in evaluating the long-term effects of Internet-based support for diabetes self-management. The discussion identifies directions for future research.     

Undergraduate students' knowledge of infant and child development in a sample from a religiously-oriented university

Knowledge of child rearing is based on many factors. In the present study, 85 undergraduates (56 women, 46 Catholic) enrolled in psychology classes at a private university completed the Student Knowledge of Child Development Scale. Analysis showed a moderate relationship between scale scores with whether participants had taken a child development class and whether participants stated highest priority was a career or marriage and children.     

Impact of End-of-Life Circumstances on the Adjustment of Bereaved Siblings of Children Who Died from Cancer

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.
