Effect of Color Coding on Visually Oriented Tests With Students of Different Cognitive Styles

The purpose of this study was to examine the effects that differentially coded (black and white and color) illustrations had on students (N = 117) who were classified as field dependent, field neutral, or field independent as a result of their performance on the visually oriented Group Embedded Figures Test (Witkin, Olt-man, Rashin, & Karp, 1971). Students were randomly assigned to two instructional treatments complemented by illustrations (black and white and colored). After receiving their respective treatments, students reviewed two visually oriented criterion tests. Two-way analyses of variance conducted on achievement scores indicated that field independents scored significantly higher than did field dependents on both visual tests, and differences between field-dependent and field-independent learners who received the color-coded treatments on the visual identification test were insignificant. Results indicate that field dependency is an important instructional variable and that for some types of learning objectives the process of color coding instructional materials may reduce achievement differences attributed to differences in cognitive style.     

Aurelius Augustine on Imagination

The evaluation of a person seeking or volunteering information in cooperatively or competitively oriented problem solving groups was investigated in 63 white and black, male and female, high school and college students. It was hypothesized that under cooperative conditions the seeking of information would be evaluated more positively than would the volunteering of information, while under competitive conditions the volunteering of information would be evaluated more positively than would the seeking of information. A highly trained confederate (C) engaged in either the seeking of information or the volunteering of information in four-person problem solving groups in which Ss were either cooperatively or competitively oriented. Ss rated Cs on eight bipolar scales. The results confirmed the hypothesis.     

Religiosity, Alcohol Use, and Sex Behaviors Among College Student-Athletes

College student-athletes tend to consume more alcohol, engage in sex, and report more sex partners than nonathlete students. The current study examined the relationship between religiosity (e.g., influence of religious beliefs and church attendance) and alcohol use and sex behavior among college student-athletes. Most of the student-athletes (n = 83) were religious. Influence of religious beliefs was a significant predictor of less alcohol use and less sexual activity (i.e., oral and vaginal sex, number of sex partners). However, increased church attendance was not found to be a protective factor. Findings suggest that religious beliefs may contribute to reduction of alcohol use and sexual risk among college student-athletes. Consideration should be given to incorporating religiosity aspects in sexual and alcohol risk-reduction interventions for student-athletes.     

The Process of Personal Change Through Reading Fictional Narratives: Implications for Psychotherapy Practice and Theory

This qualitative study provides an understanding of how and when individuals experience transformational change as a consequence of reading narratives. Six participants who attributed significant personal changes to reading were recruited and interviewed. The investigators used grounded theory method to analyze these interviews and identify processes through which change unfolded. The core category of the analysis was identification with characters' experiences created a safe venue to consider threat and experiment with new possibilities and perspectives. Empathizing with protagonists enabled readers to integrate new modes of responding to personally difficult situations. Implications for bibliotherapy and narrative therapy are discussed.     

Voluntary attention and the spacing effect

Three experiments were done to test the hypothesis that the spacing effect results from a voluntary decision by the subject to pay little attention to the second presentation (P₂) of an item when it occurs shortly after the first (P¹)- In all three experiments, the spacing of repetitions was varied. In Experiment I, allocation of attention was manipulated by pairing P₂ of some pictures with a signal that indicated high payoff for later retention. In Experiment II, attention was controlled more directly by requiring the subject, in one condition, to recite words aloud. In both experiments, the dependent variable was judged frequency. In neither experiment did the effect of the attention manipulation interact with that of the spacing of repetitions. In Experiment III, the number of eye fixations given a picture was taken to be a measure of attention. The number of fixations dropped from P₁ to P₂ to P₃, but was unaffected by the spacing of repetitions. The experiments provide no support for a voluntary attention explanation of the spacing effect.     

The interference of various word parts on color naming in the Stroop test

This study compared the interfering effects of various word parts on performance of the Stroop task. In different conditions, the first, middle, and last two letters of a color word formed color patches. In other conditions, random letters were attached to these word parts. In a control condition, entire words formed the color patches. While no condition produced as much interference as the control condition, the first part of a color word interfered with color naming more than other word parts. The addition of unrelated letters had little or no effect on the interference produced by the first part of a word. The results are consistent with suggestions that word perception often involves the activation of an articulatory motor program which is initiated by the first part of the word.     

Vigilance and the reinforcing properties of shock

There have been some observations to indicate that waiting for a shock is stressful, that the coining of an anticipated shock can serve as a tension reliever, and that failure to obtain an anticipated shock is more stressful than being shocked. Based on these observations, the following hypotheses were tested. If it is true that failure to receive shock is more stressful than the shock itself, it should be possible to train an animal to bring on a shock that had failed to come when anticipated. If a period of anticipating shock is stressful, and shock serves as a reliever of the stress, it should be possible to train an animal to perform a response instrumental to bringing on the shock sooner. Results indicated that shock does seem to serve as a reliever, that waiting for shock is stressful, but that failure to receive an anticipated shock under these circumstances is not more stressful than the shock itself. In addition, it was found that subjects learned to produce shock instrumentally if the shock was inevitable and could thus be brought about sooner. Results were inconclusive, though generally negative, on the issue of whether S’s would produce an avoidable shock that had failed to come when anticipated.     

Clinical practice as natural laboratory for psychotherapy research: a guide to case-based time-series analysis

Both researchers and practitioners need to know more about how laboratory treatment protocols translate to real-world practice settings and how clinical innovations can be systematically tested and communicated to a skeptical scientific community. The single-case time-series study is well suited to opening a productive discourse between practice and laboratory. The appeal of case-based time-series studies, with multiple observations both before and after treatment, is that they enrich our design palette by providing the discipline another way to expand its empirical reach to practice settings and its subject matter to the contingencies of individual change. This article is a user's guide to conducting empirically respectable case-based time-series studies in a clinical practice or laboratory setting.
