The effect of adults' eating on young children's acceptance of unfamiliar foods

Adults presented unfamiliar foods to 14- to 20- and 42- to 48-month-old children individually in their homes. More children put the food in their mouths when the adults also were eating than when the adults simply were offering the food. More children put food in their mouths when their mothers were the source than when the source was a friendly adult “visitor”. However, even when alone with a child, the visitor's eating elicited reliably more tasting. Analysis of requesting behavior indicated that the adults' eating aroused a desire to eat in the children. There were no consistent sex differences or interactions between sex of visitor and sex of child in children's food acceptance. There was a suggestion that younger children were more affected by repeated offerings than were older children. It is concluded that a relatively “low level” form of observational learning—“social facilitation”—can account for the data.     

On microprocessor-based computers

Economical microprocessor-based computers have been recently developed by Motorola and Control Logic, Inc. Apparently, in response to the price competition, DEC has introduced the PDP-8/A, incorporating the memory characteristics of the microprocessor-based computers. Relative to older minicomputers, the microprocessor-based systems and the PDP-8/A “miniprocessor” require more time to execute an experimentally useful task. However, their real-time operating characteristics would appear to be sufficient for on-line use in behavioral control and data acquisition. The PDP-8/A’s compatibility with older models of the PDP-8 series enables it to use previously developed software, but, for purposes of software development, the microprocessor systems offer a more powerful architecture and instruction set.     

Isolation of massed- and distributed-practice items

In four experiments, massed-practice (MP) or distributed-practice (DP) items were isolated from other items in a list presented either visually or auditorially for free recall. For three independent groups, the first, second, or both presentations of an item were isolated. Locus of isolation had a marginal influence on recall. When MP items were isolated, they were recalled better than DP items. Isolating the DP items enhanced the MP-DP effect. The results are congruent with the idea that the MP-DP effect in free recall results, in part, from differential rehearsal.     

Sensitivity to sucrose in smokers and nonsmokers: A comparison of TSD and percent correct measures

Ten smokers and 10 nonsmokers were compared for taste sensitivity to sucrose on two discrimination tasks, one at near-threshold (NT) concentration level and one at suprathreshold (ST) concentration level. The data were analyzed using the d_s and area under ROC curve measures based on the theory of signal detection (TSD). and by using the percentage correct responses. Analysis of both TSD measures showed smokers to be significantly more sensitive than nonsmokers on the NT .task and more sensitive on the ST task, but not significantly so. Comparison of mean percent correct responses showed no significant differences. A reflexive enhancement phenomenon was suggested as a possible interpretation. A decreased sensitivity to the bitter taste in smokers apparently results in an increased sensitivity to the sweet taste.     

Acceptability and Feasibility of Peer Assisted Supervision and Support for Intervention Practitioners: A Q-methodology Evaluation

Evidence-based interventions often include quality improvement methods to support fidelity and improve client outcomes. Clinical supervision is promoted as an effective way of developing practitioner confidence and competence in delivery; however, supervision is often inconsistent and embedded in hierarchical line management structures that may limit the opportunity for reflective learning. The Peer Assisted Supervision and Support (PASS) supervision model uses peer relationships to promote the self-regulatory capacity of practitioners to improve intervention delivery. The aim of the present study was to assess the acceptability and feasibility of PASS amongst parenting intervention practitioners. A Q-methodology approach was used to generate data and 30 practitioners volunteered to participate in the study. Data were analyzed and interpreted using standard Q-methodology procedures and by-person factor analysis yielded three factors. There was consensus that PASS was acceptable. Participants shared the view that PASS facilitated an environment of support where negative aspects of interpersonal relationships that might develop in supervision were not evident. Two factors represented the viewpoint that PASS was also a feasible model of supervision. However, the third factor was comprised of practitioners who reported that PASS could be time consuming and difficult to fit into existing work demands. There were differences across the three factors in the extent to which practitioners considered PASS impacted on their intervention delivery. The findings highlight the importance of organizational mechanisms that support practitioner engagement in supervision.     

Children’s Maternal Support-Seeking: Relations to Maternal Emotion Socialization Responses and Children’s Emotion Management

The present study examined children’s support-seeking of mothers (SSM) as a moderator of the association between maternal emotion socialization responses and children’s emotion management. Participants included 119 mother–child dyads (63 boys, M age = 9.61 years, 73.1 % Caucasian). Maternal emotion socialization was assessed via observed mother–child interactions and child report. Analyses indicated several main effects such that child-reported maternal reward responses were associated with stronger child emotion management, whereas perceived maternal punishment and neglect were associated with poorer child emotion management. Regarding the significant interactions, observed maternal general unsupportive socialization responses were negatively associated with emotion management. Additionally, for children low in SSM, child-reported maternal overriding of children’s emotions was positively associated with better emotion management. Support-seeking of mothers may mitigate the risk of some unsupportive maternal socialization responses and may be an adaptive strategy in middle childhood in particular contexts.
