Heterogeneity among specific phobia types in DSM-IV

Recently, it has been suggested that situational specific phobias (e.g., phobias of driving, flying, enclosed places) are more closely related to agorophobia than are other specific phobia types. The present study investigated this hypothesis by examining heterogeneity among the four main DSM-IV specific phobia types, particularly with respect to variables believed to be associated with agoraphobia. Using interviews and behavioral testing, 60 patients with specific phobias of animals, heights, blood/injections, or driving were compared with respect to etiology, age of onset, physiological response, predictability of panic attacks, and focus of apprehension. Fifteen patients suffering from panic disorder with agoraphobia served as a comparison group for some measures. Relative to the other specific phobias, driving phobias were most strongly associated with a later age of onset, similar to that of individuals with agoraphobia. Height phobias were also associated with a late age of onset as well as a more internal focus of apprehension, relative to other groups. Finally, individuals in the blood/injection phobia group reported a more internal focus of apprehension than those in other groups and were the only group to report a history of fainting in the phobic situation. Overall, the results did not support the hypothesis that situational phobias are a variant of agoraphobia. In fact, on several of the variables for which groups did differ, individuals with height phobias (a phobia from the natural environment type) showed a pattern most similar to individuals with agoraphobia. The implications of these results for the classification of specific phobias are discussed.     

School-Wide Behavioral Support: Starting the Year Off Right

Two years of office referral data are presented in evaluation of a school-wide behavioral support program designed to define, teach, and reward appropriate student behavior in a rural middle school (grades 6, 7, and 8). During 1994-95, the school had 530 students and recorded 2,628 office referrals. The 1995-96 school year began with a full day in which students were taught five school expectations. Throughout the year, students also received rewards for appropriate behavior and office referrals for infractions. Results during 1995-96 document a 42% reduction in office referrals from the previous year. While the evaluation results do not document functional relationship, they suggest an efficient process for evaluating school-wide behavioral support, teaching appropriate behaviors, and changing the overall climate of the school. Implications for future research, and the use of schools as a unit of analysis, are discussed.

Individual Differences in visual imagery and spatial ability

Spatial ability is generally assumed to involve construction, transformation, and interpretation of mental images. To explore the relationship between spatial ability and both image quality and image process efficiency, 79 subjects performed eight spatial tests, completed three imagery questionnaires, and participated in six laboratory tasks. These laboratory tasks were devised to measure image quality and the efficiency of image generation, image rotation, image scanning, adding and subtracting detail in images, and integration of images. Although ratings of imagery control and vividness were unrelated to spatial test performance, laboratory measures of process efficiency and image quality were strongly related to spatial test performance and weakly related to one another. A structural equation model identified a single spatial factor, Visualization ability, that can be decomposed into unique variance plus a linear combination of measures of image quality and image process efficiency. An interpretation of this model is that successful performance on spatial tests requires maintenance of a high-quality image and efficient image transformation and inspection processes.     

The role of plausibility in influencing environmental attributions

The aim of the study was to examine how plausibility influences attributions about the cause of perceived arousal. Subjects watched one of three arousing (humorous, sexual, aggressive) or a nonarousing televised program under conditions of appropriate or inappropriate interpersonal spacing. The subjects then completed a questionnaire indicating how crowded they felt and rating the movie on a number of dimensions. The results indicated that under close interpersonal distances, subjects felt less crowded while watching the arousing movies than while viewing the nonarousing movie. There were no differences in the experience of crowding between the movie conditions under the far interpersonal distance conditions. In addition, subjects rated the arousing movies as more arousing under close as opposed to far interpersonal distance conditions. Further, the humorous movie was viewed as more funny, and the violent movie was rated more violent under the close as opposed to the far conditions. Finally, there was a tendency to enjoy the arousing movies more under the close conditions, while the reverse effect was found for the nonarousing movie. It was argued that the arousing movies reduced the experience of crowding under close interpersonal conditions because subjects attributed their arousal to the movies rather than to the spatial restrictions. It was further suggested that the results showed that individuals will attribute their arousal to salient stimuli in their environment that could plausibly be sources of arousal. The results not only offer support for an attribution model of crowding, but they also show that depending on the individual's attribution, spatial conditions that can give rise to crowding may increase enjoyment of events in the environment.     

STM Experimenter: Using HyperCard and MacRecorder in short-term memory experiments

We describe a Macintosh program for the presentation of spoken word lists in short-term memory (STM) experiments. The program was developed with the use of HyperCard and MacRecorder. Parameters such as rate of item presentation, number of items per trial, and number of trials per block may be adjusted by the experimenter. The program features high-quality digitized sound, trial-to-trial word list randomization, and data logging. Computer-based experimentation offers several advantages over traditional approaches that involve tape recordings or lists read aloud by the experimenter. Methodological improvements afforded by computer-controlled item administration are discussed.     

Aerobic exercise in the psychological treatment of adolescents.

A small group of psychiatrically institutionalized adolescents (16 boys, 11 girls) were assigned to a three-day-per-week running/aerobic exercise program or a regular physical activity class. The complete program continued over 9 weeks, with 11 subjects remaining throughout the program. Dependent measures of body-mass index, timed performance on a one-mile run, resting, exercise, and recovery heart rates, and measures of depression, mood-states, and self-efficacy were assessed pre-, mid-, and post-9-wk. treatment and at a 4-wk. follow-up. Improvements in depression, anxiety, hostility, confused thinking, and fatigue were shown in treated girls, with increases in vigor and self-efficacy for all treated subjects.     

Ethnic differences in adolescent achievement. An ecological perspective.

Using data collected from a large sample of high school students, the authors challenge three widely held explanations for the superior school performance of Asian-American adolescents, and the inferior performance of African- and Hispanic-American adolescents: group differences in (a) parenting practices, (b) familial values about education, and (c) youngsters' beliefs about the occupational rewards of academic success. They found that White youngsters benefit from the combination of authoritative parenting and peer support for achievement, whereas Hispanic youngsters suffer from a combination of parental authoritarianism and low peer support. Among Asian-American students, peer support for academic excellence offsets the negative consequences of authoritarian parenting. Among African-American youngsters, the absence of peer support for achievement undermines the positive influence of authoritative parenting.
