Married couples seeking sex therapy, marital therapy, or no form of therapy were compared with respect to personality, sexual and marital functioning. The Sexual Dysfunction and Marital Difficulties groups (15 and 10 couples respectively) were obtained from the waiting lists of a sexual dysfunction service and marital therapy unit. Non-Problem subjects (15 couples) were from a volunteer sample. Personal adjustment, sexual and marital functioning were assessed by means of the Eysenck Personality Inventory, a Sexual Behavior Questionnaire, the Locke-Wallace Marital Adjustment Survey, and the Azrin Marital Happiness Scale. Results indicated that although all three groups were within the normal range, problem couples had higher ‘neuroticism’ scores than did Non-Problem couples. Marital Problem couples were the most debilitated. Their marital adjustment was lowest, and their sexual functioning was comparable to the Sexual Dysfunction group. Marital adjustment of the Sexual Dysfunction couples was significantly higher than that of the Marital Difficulties couples. Therapeutic and theoretical implications of the differentiating characteristics in the three couple categories are discussed. 相似文献

A simple laboratory computer system based on a Digital Equipment Corporation LSI-11, floppy disk, DRV11 parallel input-output board, and the RT-11 operating system is described. Interface to experimental devices is provided through a lab-built relay driver and relay closure sensing interface. An extensive high-level software package provides an easy-to-use control language (e.g., stimuli can be controlled with a simple “TURN ON” or “TURN OFF” instruction) and easy-to-use FORTRAN subroutines for data exploration (e.g., “IFIND” searches a data file for a particular event). The control software automatically generates, codes, and stores a complete log of every input and output event and its time of occurrence in each of five simultaneously running experiments. This provides the capability to reanalyze data in light of hypotheses not available when the experiment was designed. The FORTRAN subroutine library for data exploration provides a conditional and iterative search facility to sift out events or sets of events from the data file for analysis. Standard FORTRAN statements perform arithmetic operations on the resulting data. 相似文献

A distinction between compound and coordinate bilingualism has been employed to conceptualize linguistic organization in bilinguals. Compound bilinguals are those who acquired their languages in a joint context and therefore are presumed to store linguistic information interdependently. Coordinates include those who acquired their languages in separate contexts and therefore are presumed to maintain independent linguistic stores. To study the usefulness of this distinction, Spanish-English and English-Spanish, compound, and coordinate bilinguals were asked to give intra-and interlingual free and restricted word associations to equivalent English and Spanish stimuli for which the responses of monolingual speakers were not equivalent. As predicted, compound bilinguals gave significantly more equivalent responses and responded significantly faster than did coordinates. However, since these differences were only modest in size, they cannot be interpreted as supporting the usefulness of the compound-coordinate distinction. None of the predictions regarding the effect of proficiency on performance were supported. Differences as a function of native language, type of association task, and association conditions were obtained and are discussed.This research was supported by USPHS Grant HD 01368 to Dr. Klaus Riegel, University of Michigan, and was included as one portion of a doctoral dissertation submitted by the author to the Horace H. Rackham School of Graduate Studies at the University of Michigan. 相似文献
