Design considerations for multidimensional scaling

This paper begins with a short tutorial on multidimensional scaling. The focus of the remainder of the paper is on the proper designing of research that will use multidimensional scaling analysis techniques and includes suggestions for the interpretation of results.     

Acute effects of viloxazine HCl and flurazepam when given alone and in combination on sleep EEG: A double-blind interaction study with normals

Viloxazine, an aryl-oxypropanolamine type β-adreno-receptor antagonist, has been used in the treatment of depression. In a double-blind drug interaction study with flurazepam, a commonly used benzodiazepine hypnotic, viloxazine administered alone decreased the amount of time spent in REM sleep, increased the amount of time in the “light” stages of sleep, and increased the number of transitions to awake. However, no interactive effects of the combined administration of viloxazine and flurazepam could be detected.     

Perceptions of assertive behavior: Sex combination,role appropriateness,and message type

Eighty-four male and 84 female subjects, divided into high, moderate, and low groups on the basis of sex-role stereotyping, watched videotapes of two-person interactions where positive and negative assertive messages were sent by male and female actors to male and female receivers. Subjects rated the level of assertion and the social acceptability of each message. Results indicated that while all messages were rated as relatively assertive, negative messages were perceived as more assertive and less socially acceptable than positive ones. Subjects also rated male senders as more assertive than female senders when the message type was role inappropriate for the subjects but rated female senders as relatively more assertive when the message type was role appropriate for them. Messages from female senders were rated as more socially acceptable than messages from male senders. Finally, messages to male receivers were rated as more acceptable than messages to females, especially by male subjects when the sender was male. Thus, both sex-role stereotypes and situational expectations appear to influence perceptions of level of assertion, and more assertive messages are perceived as less socially appropriate.     

Parent–Adolescent Collaboration: An Interpersonal Model for Understanding Optimal Interactions

Current parent–adolescent behavioral interaction research highlights the importance of three elements of behavior in defining adaptive interactions: autonomy, control, and warmth vs. hostility. However, this research has largely addressed the developmental needs and psychosocial outcomes of adolescents, as opposed to parents, with a focus on how parent and adolescent behaviors influence adolescent adaptation. This paper utilizes both adolescent and mid-life developmental research, as well as parent–adolescent interaction research, to introduce a model for conceptualizing parent–adolescent interactions as a transactional process in which both parental and adolescent development are considered. Further, ideas are presented describing how adaptive parent–adolescent interactions may change across adolescence. The concept of collaboration is proposed as a conceptual tool for assessing one form of adaptive parent–adolescent interactions. The structural analysis of social behavior (SASB) is presented as a model for studying the complex reciprocal processes that occur in parent–adolescent interpersonal processes.     

Youth with Chronic Pain and Postural Orthostatic Tachycardia Syndrome (POTS): Treatment Mediators of Improvement in Functional Disability

Intensive pain rehabilitation programs are effective in increasing functioning for youth with chronic pain (CP). However, the utility of such programs for youth with CP and co-morbid postural orthostatic tachycardia syndrome (POTS) is rarely examined. In addition, studies examining mediators of treatment for CP are sparse. This paper compares treatment outcomes for youth with CP (n?=?117) and youth with CP?+?POTS (n?=?118). Additionally, depression and pain catastrophizing were tested as potential mediators of treatment effects. Significant treatment improvements were found for functional disability, depression, pain catastrophizing, and perceived pain intensity but with no differences between groups. Improvements in depressed mood, pain catastrophizing (helplessness subscale), and pain severity partially mediated functioning improvement. Pain severity was not a significant mediator in the CP?+?POTS group. We concluded that depression and pain catastrophizing, especially the helplessness domain, can impact functioning improvement in adolescents with CP and POTS and are particularly important to target in treatment.     

Idiomatic processing: Syntactic frozenness and subjective familiarity

Summary Four experiments are reported that investigated idiomatic processing. Two experiments collected subjects' ratings of frozenness, familiarity, and meaningfulness for a set of idioms. The ratings obtained were used to assess the contributions of these dimensions to performance in two experiments that utilized a phoneme-identification task. Ambiguous and unambiguous phoneme targets occurred as the initial sound in the final word in idiomatic and neutral carrier phrases. Subjects' phoneme identifications were biased in the labeling of ambiguous segments in that identification responses in the idiom context tended to form an idiomatic phrase, more so than those in the neutral carrier phrase. Additional correlational analyses suggested that an idiom's degree of influence on identification depended on the rated syntactic frozenness. For subjects who knew the idioms, familiarity did not account for the biasing effect of idiomatic contexts. The experiments are discussed in terms of theories of auditory word recognition and the representation of frozenness in the mental lexicon.This research was supported by NIDCD Grant R29 NS26 587 to the first author.     

Power and Action in Critical Theory Across Disciplines: Implications for Critical Community Psychology

Although critical scholarship and community psychology share similar aspirations, the links between them remain unexplored and under-theorized. In this article we explore the implications of critical scholarship in various specialties for the field of community psychology. To understand the contributions of critical scholarship to a theory of power and action for social change, we conducted a systematic analysis of a ten-year period of publications in seven journals associated with the critical scholarship tradition. We created precise criteria for the concepts of power and action and applied them to the publications. Results indicate an interesting paradox at play. Whereas community psychology is more action oriented than critical scholarship, its actions fall short of challenging institutionalized power structures and the status quo; and whereas critical scholarship is more challenging of the status quo than community psychology in theory, it has failed to produce viable actions that challenge the status quo. We discuss the implications of this state of affairs for the development of a more critical community psychology.
