The real and the ideal; gender differences in heterosexual behaviour among Norwegian adolescents

This article focuses on gender differences in early heterosexual behaviour among Norwegian adolescents. The material comprised a random sample of 3000 Norwegian adolescents aged 17–19 years. The response rate was 63%. Data were collected by means of anonymous self-administered questionnaires. Sixty-nine per cent of the girls and 59% of the boys had had sexual intercourse. The majority of the adolescents, and a larger percentage of girls than of boys, had their first intercourse within a relationship of mutual commitment. The boys' first coital partners were 0.2 years younger than the boys themselves and the girls' partners were 2.8 years older than were the girls. Boys had had more coital partners than girls but girls had had intercourse more often than boys. Coital frequency was affected more by how long the adolescents had known the partner than by gender as such. In conclusion, boys and girls aged between 17 and 19 years form part of couples at two different stages of development. For this reason, boys and girls accumulate different sexual experiences in the early stage of their sexual careers.     

Sequential effects in dimensional contrast

Two experiments examined pigeons' response rates during short trials signaled by stimuli closely spaced along a wavelength continuum. In Experiment 1 separate halves of the continuum were correlated with different reinforcement schedules. In Experiment 2, the middle stimulus was accompanied by a lower probability of reinforcement than were the remaining wavelengths. Both procedures resulted in dimensional contrast “shoulders,” seen as relatively enhanced or depressed response rates in the presence of stimuli between the extreme of the continuum and the border separating the positive and negative stimuli. Sequential analyses addressed possible contributions of the following interactions: (a) local contrast, seen when rate during a given schedule depends on the schedule in the just-preceding trial; (b) modification of local contrast by the similarity of the signaling stimuli (P. Blough, 1983); and (c) schedule-independent rate contrast, seen when rate in a given trial depends on the rate controlled by the stimulus that accompanied the just-preceding trial (Malone & Rowe, 1981). Dimensional contrast functions were similar when isolated according to the schedule, to the similarity of the signaling stimulus, and to the response rate of the just-preceding trial. The interactions noted above do not appear to make important contributions to this effect.     

Clinician experiences of homework in couples and family therapy: A survey of perceived impact on the working alliance

The process of engaging clients in homework assignments has been studied extensively in research settings, but rarely have the challenges in the implementation of the science been considered in couples and family therapy. A survey was conducted of 226 clinicians regarding (1) their experience of homework adherence (quantity and quality) with couple and family clients, and (2) their experience of the impact of homework non-completion (IHN) on the working alliance. Clinicians working with families reported less overall homework quantity and quality. However, across both couples and family clients, more negative IHN was reported among clinicians experiencing less homework quantity, both in terms of IHN bond (couple ρ = 0.71, p < 0.001; family ρ = 0.78, p < 0.001) and IHN agreement (couples ρ = 0.25, p < 0.001; ρ = 0.19, p = 0.006), and among clinicians with fewer years of clinical experience (r = 0.19, n = 136, p < 0.05). The present findings suggest that, in the context of couples and family therapy, there is a risk of perceived negative IHN on the working alliance. There would be merit to future investigations examining the processes of facilitating homework engagement within the context of a strong working alliance.     

When left hands touch: shadow vows and Jung’s quaternity

Is there a connection between the exchange of vows and the fighting and suffering of couples that are unique to the institution of marriage? This essay introduces the concept of Shadow Vows, the unacknowledged assumptions, agreements, and obligations each partner brings to the relationship, which the authors believe are often responsible for longstanding marital discord and strife. The authors ground the existence of shadow vows in Jung’s quaternity, alchemy, typology, archetypal theory, and depth approaches to couple therapy. The essay concludes with a list of themes indicative of shadow vow enactments in clinical work with couples.     

Taking stock of the longitudinal study of romantic couple relationships: The last 20 years

Longitudinal dyadic research provides significant benefits for our understanding of romantic couple relationships. In this systematic review, we begin by providing a broad overview of topical trends and approaches in longitudinal couple relationships research from 2002 through 2021. Then, we narrow our review to dyadic relationship quality articles, highlighting key themes as well as noting important gaps in the research. Using an intersectional perspective that acknowledges multiple ways that disadvantage, power, and oppression may be seen in both research and in couples' lived experience, we note prominent paradigms used in examining couple relationships, what types of questions have been most valued, and what groups and approaches are underrepresented in the literature. Most longitudinal couple relationships research is quantitative, relies on self-report approaches from American couples in the early-to-middle years of their relationships, concentrates more on negative aspects of relationships than positives, and takes a communication-satisfaction paradigm in studying couples. We see a clear need to increase the use of methodologies beyond self-report measures, conduct more studies with within-group minority, older adult, culturally-diverse, and context-specific samples to explore the diversity of relationships, and fully consider both strengths and positive processes in relationships as well as the challenges couples experience.     

“What matters to us”: The portrait values questionnaire to measure couple values

No previous studies have analyzed values as qualities of relational microsystems, such as the romantic couple. Based on Schwartz's Theory of Human Values, this study examines the psychometric properties of the Portrait Couple Values Questionnaire (PCVQ). It measures four couple value dimensions: conservation, openness to change, self-enhancement, and self-transcendence. Five hundred and forty-six Italian respondents (54.1% women), aged 41.52 years (SD = 7.19; range 23–63) and having a couple relationship, have filled in an anonymous online questionnaire. The results show the good psychometric properties of the PCVQ. The Confirmatory Factor Analysis Magnifying Glass Strategy shows good indexes of fit for each value dimension, except for the Root Mean Square Error of Approximation (RMSEA) for openness to change, thus confirming that the PCVQ measures the four values with satisfactory internal consistency. The Multidimensional Scaling results, by showing a Stress-1 index of 0.07, confirm the circular structure of values because the four value dimensions are in the position predicted by Schwartz's model. Participants' personal and couple values are highly but not perfectly correlated, suggesting that couple values are a related but distinct construct compared to personal values. This study's contribution lies in introducing an innovative construct into the literature on values and couples, proposing a scale to assess it.     

A Logic for Reasoning about Relative Similarity

A similarity relation is a reflexive and symmetric binary relation between objects. Similarity is relative: it depends on the set of properties of objects used in determining their similarity or dissimilarity. A multi-modal logical language for reasoning about relative similarities is presented. The modalities correspond semantically to the upper and lower approximations of a set of objects by similarity relations corresponding to all subsets of a given set of properties of objects. A complete deduction system for the language is presented.     

Similarities derived from 3-d nonlinear psychophysics: Variance distributions

Many-one mappings between stimulus properties and pairwise generated similarities are intrinsic to definitions of similarity. This of itself is not sufficient as a basis for predicting the variance associated with any single similarity judgment. An extension to cover this has to be made either by making ancillary assumptions about noise, or by using nonlinear models. The derivation of the variance of similarity judgments is made from the 3 process in nonlinear psychophysics. The idea of separability of dimensions in metric space theories of similarity is replaced by one parameter which represents the degree of a form of interdimensional crosscoupling
