Response rate viewed as engagement bouts: resistance to extinction

Rats obtained food pellets by nose poking a lighted key, the illumination of which alternated every 50 s during a session between blinking and steady, signaling either a relatively rich (60 per hour) or relatively lean (15 per hour) rate of reinforcement. During one training condition, all the reinforcers in the presence of the rich-reinforcement signal were response dependent (i.e., a variable-interval schedule); during another condition only 25% were response dependent (i.e., a variable-time schedule operated concurrently with a variable-interval schedule). An extinction session followed each training block. For both kinds of training schedule, and consistent with prior results, response rate was more resistant to extinction in the presence of the rich-reinforcement signal than in the presence of the lean-reinforcement signal. Analysis of interresponse-time distributions from baseline showed that differential resistance to extinction was not related to baseline differences in the rate of initiating response bouts or in the length of bouts. Also, bout-initiation rate (like response rate) was most resistant to extinction in the presence of the rich-reinforcement signal. These results support the proposal of behavioral momentum theory (e.g., Nevin & Grace, 2000) that resistance to extinction in the presence of a discriminative stimulus is determined more by the stimulus-reinforcer (Pavlovian) than by the stimulus-response-reinforcer (operant) contingency.     

Academic and clinical education in fluency disorders: an update

This paper presents a survey of the academic and clinical education in fluency disorders provided by American Speech-Language-Hearing Association (ASHA)-accredited training programs. Respondents were 159 programs (out of 256, return rate = 67.4%) that completed a questionnaire seeking information about the courses and clinical experiences they require, the expertise of their faculty and supervisors, changes following the 1993 modification of training requirements for the ASHA certificate of clinical competence (CCC), and preliminary plans for changes in preparation for the 2005 standards. Results, which supplement findings from an earlier survey distributed in 1997 (Yaruss, 1999), indicated that nearly one-quarter of programs allow students to graduate without coursework in fluency disorders, and nearly two-thirds allow students to graduate without clinical practicum experiences. Findings suggest a trend toward fewer required classes taught by less experienced faculty, fewer clinical hours guided by less experienced supervisors, and a greater likelihood that students will graduate without any academic or clinical education in fluency disorders. Given the repeated finding that many speech-language pathologists are uncomfortable working with people who stutter, as well as ASHA's apparent de-emphasis of fluency disorders within the increasing scope of practice in the field of speech-language pathology, these results are a cause for concern about the future of fluency disorders. EDUCATIONAL OBJECTIVES: The reader will learn about (1) the coursework and clinical practicum experiences that are currently required for students in ASHA-accredited training programs; (2) trends indicating a reduction in training requirements for fluency disorders; and (3) ways of improving these requirements.     

Sex Under Pressure: Jerks,Boorish Behavior,and Gender Hierarchy

Pressuring someone into having sex would seem to differ in significant ways from pressuring someone into investing in one’s business or buying an expensive bauble. In affirming this claim, I take issue with a recent essay by Sarah Conly (‘Seduction, Rape, and Coercion’, Ethics, October 2004), who thinks that pressuring into sex can be helpfully evaluated by analogy to these other instances of using pressure. Drawing upon work by Alan Wertheimer, the leading theorist of coercion, she argues that so long as pressuring does not amount to coercing someone into having sex, her consent to sex answers the important ethical questions about it. In this essay, I argue that to understand the real significance of pressuring into sex, we need to appeal to background considerations, especially the male-dominant gender hierarchy, which renders sexual pressuring different from its non-sexual analogues. Treating pressure to have sex like any other sort of interpersonal pressure obscures the role such sexual pressure might play in supporting gender hierarchy, and fails to explain why pressure by men against women is more problematic than pressure by women against men. I suggest that men pressuring women to have sex differs from the reverse case because of at least two factors: (1) gendered social institutions which add to the pressures against women, and (2) the greater likelihood that men, not women, will use violence if denied, and the lesser ability of women compared to men to resist such violence without harm. I would like to thank Marcia Baron, Sylvia Berryman, Elizabeth Brake, Dominic McIver Lopes, Jennifer Warriner, Janet Wesselius, two anonymous reviewers for Res Publica and the audiences at the University of British Columbia Feminism and Philosophy Workshop and the Western Canadian Philosophical Association meetings in Winnipeg for helpful discussion and comments.     

Body image and risky sexual behaviors: an investigation in a tri-ethnic sample

The impact of negative body image on risky sexual behaviors has not been extensively investigated. The present study examined the relationship between two aspects of body image, appearance shame and appearance investment, and potentially risky behaviors. The study employed a tri-ethnic sample of 1547 women seeking services at two family planning clinics. Logistic regression was utilized to examine the relationship between potential risk behaviors and shame and investment. Results supported that these aspects of body image were significant predictors of inconsistent condom use, having multiple sex partners in the past year, and having sex after drinking alcohol or using drugs, and that demographic variables (e.g., age, marital status, ethnicity) could not fully account for these relationships. The importance of future research investigating the relationships among body image, perceived relationship security, affect-management strategies, and risky sexual behaviors is emphasized.     

An Integral Psychology Response to Helminiak's (2001) “Treating Spiritual Issues in Secular Psychotherapy”

This article is a response to D. A. Helminiak's (2001) “Treating Spiritual Issues in Secular Psychotherapy” from the perspective of K. Wilber's integral psychology. The article consists of 3 sections: (a) a selective summary of integral psychology, including the perennial philosophy, 10 levels of development, lines of development, temporary states, types of orientations, the self, and the 4 quadrants; (b) various conceptual issues; and (c) usefulness to mental health practitioners (MHPs). Although D. A. Helminiak's endeavor to formulate a clear and functional definition of spirituality is commended, his claim of novelty is shown to be unwarranted. It is argued that K. Wilber's integral model is more comprehensive, clear, coherent, and helpful to MHPs.     

Ignorance May Be Bliss, But Thought Suppression Promotes Superficial Cognitive Processing

This study examined the impact of thought suppression on the quality of cognitive processing and self-reported mood. While completing a stream-of-consciousness task about two topics sequentially, participants were either instructed to suppress negative thoughts or were given no suppression instructions. Computer-based content analyses indicated that thought suppression led to significantly less causal reasoning and discrepancy seeking. However, the suppression of negative thoughts also resulted in a more positive mood. Results suggest that thought suppression can improve mood but it comes with the cognitive cost of superficial processing.     

FUNCTIONAL ANALYSIS AND TREATMENT OF INAPPROPRIATE VERBAL BEHAVIOR

The present study examined the possible function of inappropriate verbal behavior of an adult man who had been diagnosed with both mental retardation and psychosis. Results of a functional analysis indicated that inappropriate verbal utterances were maintained by attention. An intervention consisting of the differential reinforcement of appropriate verbal behavior effectively reduced the inappropriate behavior.     

Familiar eyes are smiling: on the role of familiarity in the perception of facial affect

Quickly and accurately perceiving others' facial affect is paramount for successful social interaction. This work investigates the role of familiarity in helping us to interpret others' facial emotions. In Experiments 1 and 2, participants viewed several faces, some familiar and some novel, and judged how happy each face appeared. As predicted, results showed that familiar faces were perceived as happier than were novel faces. In Experiment 3, participants again viewed several faces, some familiar and some not, and rated the perceived anger or happiness of these faces. As expected, familiar faces were perceived as happier and less angry than were novel faces. Thus, these results suggest that familiarity is one cue we use to interpret the facial affect of others.

Lack of autonomy and self-control: Performance contingent rewards lead to greater depletion

Exerting self-control appears to deplete a needed resource, which leads to poorer self-control subsequently. However, the amount of depletion may vary, based on how controlling versus autonomy supportive the situation is. In particular, feeling compelled to exert self-control may deplete more strength than having more freedom when exerting self-control. In three experiments, participants who were given performance contingent rewards to exert self-control performed more poorly on a subsequent test of self-control than participants who were non-contingent rewards. There were no differences in mood, arousal, or anxiety between the groups; however, feelings of autonomy were related to self-control performance. The results have implications for understanding self-control depletion, as well as the impact of autonomous motivation on self-control performance.
