A comparison of flooding and thought stopping in the treatment of obsessional neurosis

Flooding in vivo and thought stopping were compared in patients with obsessional neurosis, in a cross-over design. It was hypothesized that the two techniques would have different effects on symptomatology. However, although both seemed to be effective treatments, there were no significant differences between them. Reasons for this finding are discussed. There was, however, a slight tendency for flooding to produce more overall improvement, and a greater reduction in avoidance behaviour. There was also a tendency for the first treatment to produce more effect. A worthwhile clinical finding was that a fair amount of improvement occurred after only eight out-patient sessions.     

Progressive elaboration and memory for order in children

Three experiments were conducted investigating memory for items and order in a progressive elaboration paired-associates task. For all subjects retention of item information was improved by the use of progressively elaborated interactions relative to a no-elaboration control condition. For second and fourth graders, retention of order information depended upon the type of elaboration. If successive interactions were added in a logical temporal order, retention (of order information) was superior to the case where the successive interactions were added in a random order. This effect was not obtained with kindergarten children. In the second and third experiments, kindergarteners were instructed regarding the sequencing of the successive items, and results similar to those obtained with older children ensued. The data were discussed in terms of Tulving's distinction between episodic and semantic memory.     

Memory for instances and categories in children and adults

College subjects and 7-year-olds were trained in sorting 16 words into two conceptual categories. Training consisted of either three list presentations (Experiment I) or training to solution (Experiment II). Then either immediately or after a 3 to 4 week delay subjects received a recognition test which assessed memory for the instance vs categorical properties of the task stimuli by embedding words from the original list and from the list categories with confusion items from either the same or different categories as those on the original list. The data indicated that learning and memory were controlled primarily by categorical properties of the task items in adults and by specific instance properties in children. However, there was evidence that children had learned the categorical attributes of the task and may have differed from adults chiefly in their failure to utilize these attributes to assist learning and memory performance. The age differences in learning and memory were independent of the degree of initial training.     

The effectiveness of a simulation technique as an integral part of a school psychology training program

A modified Solomon design was employed to study the effects of a school psychology simulation package on the enacted and written response of a group of school psychology preservice students. Fifty-two school psychology students from five training programs enrolled in the last quarter of school psychology training prior to internship were divided into two groups. The experimental group (N=20) received the simulation experience, whereas the control group (N=32) did not. Results generally indicated the superiority of the experimental group and suggested that simulation as an integral part of a school psychology training program is an effective method of instruction. Pretesting in combination with the simulation training improved posttest performance more than simulation training alone.     

The effects of elimination of hand gestures and of verbal codability on speech performance

Subjects were required to describe line drawings of two-dimensional shapes at two levels of verbal codability, with and without using hand gestures. Elimination of gesture affected speech performance by changing the semantic content of utterances and the proportion of speaking time spent pausing; numbers of words, numbers of pauses, mean pause length and semantic content were found to be related to the verbal codability of the stimulus material; and the number of hesitations was related to both gesture and level of codability.     

The effect of modeling and vicarious reinforcement upon the subsequent imitation of a socially approved response

This study tested whether modeling and positive vicarious reinforcement produced imitation of a socially approved behavior. Eighty-eight fourth-grade girls were divided into four groups: three experimental and one control. The experimental groups watched a video tape of a peer model drawing. In one condition the model was praised; in the second, no praise was given and a short interval elapsed before the S could model the behavior; in the third, no praise was given and the S could model the behavior immediately. The control group watched a blank screen. Significant modeling effects occurred among those Ss exposed to the tapes (p < .001). Positive vicarious reinforcement, however, did not further facilitate the modeling effect. The data were discussed in light of the practicality and feasibility of using modeling procedures in the schools.     

THE APPLICATION OF GENERALIZED CORRECT SOCIAL CONTINGENCIES: AN EVALUATION OF A TRAINING PROGRAM1

Two aides operating a kindergarten-style program for institutionalized mental retardates were trained, using observer feedback, to apply generalized “correct” social contingencies to 10 defined classes of appropriate and inappropriate child behaviors. A multiple baseline design was used to demonstrate, sequentially, the effects of the training procedure upon the attending behavior of each teacher. After withdrawal of feedback, a posttraining follow-up served to assess the durability of training. For both aides, the effect of training was to increase the proportion of appropriate child behaviors attended to, compared with baseline data, and a follow-up over a number of weeks indicated that the effects of training were apparently durable.     

The role of overt activity in children's sentence production

Nursery schooler's abilityto associate pairs of toys was assessed under four experimental conditions: (1) control, (2) S manipulating the toys, (3) S generating a sentence, and (4) S generating a sentence while manipulating the toys. All three S-involvement conditions produced significantly better recognition performance than the control but contrary to initial predictions, the difference between the sentence-only and sentence-plus-manipulation conditions was not significant. In contrast to previous research, Ss in the sentence-only conditions had little difficulty producing sentences when asked. Of interest was the finding that the quality of sentence production was poorer in the sentence-plus-manipulation condition than in the sentence-only condition. Results are discussed in terms of the possible “conflict” produced when the child is required to engage in more than one overt activity simultaneously.     

Using visual codes for comparisons of pictures

In two experiments, Ss indicated for a series of trials whether or not two pictures of common objects had the same name (a positive or negative response, respectively). The pictures were separated by one of three interstimulus intervals (ISis), and reaction time (RT) was recorded. In Experiment I, positive trials involved pictures that were identical (identity match), mirror images (mirror match), or physically different but had the same name (name match). The stimuli came from either an S set, in which name-match pairs were physically similar, or a D set, in which name-match pairs were physically dissimilar. The mean RTs for mirror and identity matches were virtually the same but faster than name-match RTs, an advantage that decreased with increasing ISI. It was expected that name-match RT for the S set would be less than for the D set, indicating a facilitative effect of physical similarity; however, the identity-match RTs showed the expected difference. These results were extended in Experiment II, which involved only the identity and name matches, in pure sessions (which included positive trials of just one type) or mixed sessions (which included both types of positive trials). For mixed sessions, name- as well as identity-match RTs differed between the S and D sets. These results provide evidence for the use of visual codes in comparing nonidentical pictures, codes that apparently vary with experimental context and task demands.
