THE EFFECT OF INFORMATIONAL FEEDBACK ON FOOD INTAKE OF ADULT BURN PATIENTS

The effect of informational feedback on the protein and caloric consumption of burn patients was investigated using a multiple-baseline across subjects. The patients were four severely burned adult males who failed to consume sufficient foods to achieve prescribed levels of protein or kilocalories via standard burn unit procedures during recovery. Feedback consisted of informing patients of (a) their prescribed levels of protein and kilocalories, (b) the protein and kilocalorie content of hospital foods and beverages, and (c) their actual intake of protein and kilocalories. Following the provision of feedback, there was an increase in protein and kilocalorie intakes and in the number of days during which prescribed levels for protein and kilocalories were achieved. These results suggest that the informational feedback was effective for improving the oral caloric intake of burn patients.     

Investigations of the reinstatement of extinguished fear

In two experiments, fear was conditioned to the situational cues in one compartment of a hurdle-jumping apparatus and was then extinguished. Subsequently, either one shock (Experiment 1) or three or nine shocks (Experiment 2) were given in a situation distinctively different from that in which conditioning and extinction had taken place. Although some associative strength between the situational cues and fear was shown to have remained after extinction, in neither experiment did the postextinction-shock treatment increase the fear elicited by these cues: Escape-from-fear performance was no better in the shocked groups than in control groups given no additional shock. Thus, the nonassociative hypothesis which postulates that inflating the value of the representation of the UCS with shock-alone presentations can reinstate the extinguished fear of a stimulus was not supported. Rather, the results showed that, after extinction, an increase in fear of a simulus depended on further conditioning to that stimulus. The data also indicated that the nonvisual components of the situational cues predominated over the visual component.     

John Henry Newman on the presence of God in the Eucharist; an inspiration for reflecting on the truth of dogma1

John Henry Newman is known for his consistent, coherent, and sincere thought on the questions of faith that were important to him and his communities. Newman shares philosophical and theological reflections in many works, such as, a complex analysis of philosophical and theological aspects of faith and a subtle articulation of infallibility. Yet, Newman provides relatively little on the Eucharist. As a Tractarian, Newman raises the philosophical issue of presence in the Eucharist, distinguishes between local and real presence, and articulates his faith in the latter. As an Oratorian, Newman does not write a treatise on the Eucharist. Instead, Newman's thoughts on the Eucharist are mostly contained within prayers, devotions, meditations, and some passing commentary on the liturgy, rites, and practices of the Roman Catholic Church. Through a close reading of these texts, it is suggested that Newman provides a case study for the reflecting on the truth of dogma because of his incisive articulation of the sacramental presence of God in the Eucharist and his response to the use of the philosophical notion of transubstantiation.     

Reducing intergroup anxiety: Applying an imagined contact intervention with counselors-in-training

This study assessed the impacts of an (elaborated) imagined contact intervention (eICI) with graduate-level counseling students (N = 38) in a multicultural counseling course. Participant levels of intergroup anxiety were assessed, comparing those who completed an eICI versus those who did not. Intergroup anxiety decreased for both groups over time, albeit with a greater immediate reduction for those who received the ICI. Qualitative commentary suggests specific student learning from the activity.     

A signal detection analysis of the effects of hearing on the visual recognition of two-digit numbers

A signal detection measure of visual recognition was used to assess the visual recognition of two-digit numbers in three different conditions: (1) voicing of the number as it was presented visually; (2) voicing of a different number than the one presented; and (3) no voicing. The three treatment means were significantly different, with matched voicing resulting in the best performance and no voicing, in the worst. There was no evidence that the treatments differentially affected response criteria.     

Stimulus control and the growth of the infant’s effective visual field*

The size of the infant’s effective visual field was studied weekly in infants starting at 2 weeks of age until they were 10 weeks old, The field was initially quite small, 15 deg to either side of their line of regard. Over the 2-month period of the study, it more than doubled for stimulus conditions in which the peripheral event was in motion and the fixation object static, and it remained approximately the same size when motion was present in the fixation event and the peripheral object was static. As with adults, the infant’s effective visual field is directly related to the stimuli available.     

Response latencies in human matching-to-sample

Optimum characterization of individual information-processing skills requires isolation of assessable components. In matching-to-sample, three elementary processes might be separated if a proposed model of serial, selfterminating search were supported: registration of the stimulus in short-term memory, comparison of the two registered stimuli, and execution of the identifying response. Support for the model was obtained when response latencies were examined as a function of left-to-right position of the target stimulus in a display, but quantitative estimates of components could not be made because of interactions between tasks and the linearity of the scanning process. A second experiment, which varied the number of comparison stimuli, yielded highly linear functions whose slopes and intercepts violated certain aspects of the model. Data on eye movements obtained in a third experiment again supported the basic model but indicated that median response latencies represent a confounding of optimal and suboptimal performances.     

A suit for protecting chronically implanted devices in monkeys

The plastic barrel suit provides complete protection of chronically implanted fistulas and electrical connectors. The lost time, expense, and the frustrations of having these devices damaged was avoided.     

Humanness: A Therapeutic Variable

Since attempts by adherents to various psychotherapeutic orientations have failed to demonstrate the efficacy of any one of them, this paper tries to explicate the single variable—humanness—that seems to underlie all therapeutic approaches, and may account for the positive results obtained by all approaches. Many investigators have emphasized the importance of a positive relationship as a factor in counseling; but an influential force, behavior modification therapy, has attempted to once again place the role of technique in the spotlight. Their results have not been striking. A second aim, therefore, of this paper is to offer a critique of this position in the light of humanistic and research considerations. The implications of a technique-oriented therapeutic approach are also discussed. A plea is entered for emphasis being placed on, and an investigation of, the role of humanness as the most important variable in the counseling process.
