Derivation of likelihood-ratio tests for Guttman quasi-simplex covariance structures

In this paper, maximum-likelihood estimates have been obtained for covariance matrices which have the Guttman quasi-simplex structure under each of the following null hypotheses: (a) The covariance matrix , can be written asTT + where and are both diagonal matrices with unknown elements andT is a known lower triangular matrix, and (b) the covariance matrix *, is expressible asT*T + I where is an unknown scalar. The linear models from which these covariance structures arise are also stated along with the underlying assumptions. Two likelihood-ratio tests have been constructed, one each for the above null hypotheses, against the alternative hypothesis that the population covariance matrix is simply positive definite and has no particular pattern. A numerical example is provided to illustrate the test procedure. Possible applications of the proposed test are also suggested.Adapted from portions of the author's dissertation under the same title submitted to the Department of Psychology, University of North Carolina, in partial fulfillment of the requirements for the Ph.D. degree.

The unwanted child and mental illness: A brief,selective review

A commonly held belief is that the unwanted child is at risk for emotional disorders. This article teases out the aspects of unregulated fertility that are likely to result in an unwanted child and examines the evidence that suggest their relationship to mental illness.Samuel O.

Childhood Gender Nonconformity and Body Dissatisfaction in Gay and Heterosexual Men

Although researchers have long hypothesized a relation between gender role orientation (i.e., masculinity and femininity) and body dissatisfaction, findings have been inconsistent. The current study employed a measure of recalled childhood gender nonconformity to examine gender role behaviors in association with body dissatisfaction among an ethnically diverse (76% Caucasian, 2% African American, 8% Asian, and 16.4% Hispanic American) group of predominantly college-aged males of both homosexual (n = 129) and heterosexual (n = 52) orientation. Consistent with past research, gay males reported more body dissatisfaction and recalled more childhood gender atypical behaviors (e.g., disliking athletics, playing with dolls). Group differences in body dissatisfaction, however, disappeared when childhood gender nonconformity was statistically controlled, suggesting childhood atypical gender role behavior may place males at greater risk for adult body dissatisfaction. A within-group analysis also found that a high feminine subtype of gay males had greater body dissatisfaction than less feminine subtypes had. Results support the assertion that gender role behaviors may contribute to body dissatisfaction among gay males.     

The masculinity—Irrationality relationship explored: Searching for a common denominator

The purpose of this paper is to explore the relative empirical support for two alternative ways of interpreting the relationship between masculinity and irrationality. The common denominator in this particular relationship was theoretically assumed to either reflect a person's locus of control expectations or his/her level of self-esteem.Two separate empirical studies were performed with groups of undergraduate university students. Both studies replicated earlier results, thus supporting the masculinity hypothesis as the one accounting for the relationship between sex-role orientation and irrationality.Of the two possible common denominators explaining this relationship, level of self-esteem was the one receiving the strongest empirical support. Some interesting gender differences concerning these two possible common denominators were also found.Ole Johan Hovland, Cand.paed., is Assistant professor of Personality Assessment at the Department of Personality Psychology, University of Bergen, Bergen, Norway, and maintains a small private practice in Laksevåg, Bergen, Norway.

The "Natural" and the "Formal"

The paper presents an argument against a metaphysical conception of logic according to which logic spells out a specific kind of mathematical structure that is somehow inherently related to our factual reasoning. In contrast, it is argued that it is always an empirical question as to whether a given mathematical structure really does captures a principle of reasoning. (More generally, it is argued that it is not meaningful to replace an empirical investigation of a thing by an investigation of its a priori analyzable structure without paying due attention to the question of whether it really is the structure of the thing in question.) It is proposed to elucidate the situation by distinguishing two essentially different realms with which our reason must deal: the realm of the natural, constituted by the things of our empirical world, and the realm of the formal, constituted by the structures that we use as prisms to view, to make sense of, and to reconstruct the world. It is suggested that this vantage point may throw light on many foundational problems of logic.     

The specific nature of the clergy's role in mental health

Conclusion In this paper we have attempted to outline the basis upon which the Yeshiva University project is developing its curriculum. For the past three years and for the next two years those associated with the program will attempt to formulate the courses and training programs which could serve as the basis for a mental health educational program in seminaries. It is the hope of the Yeshiva University project that its curriculum will serve as another milestone in utilizing the resources of religion and those of other mental health disciplines to the benefit of all those who turn to religious leaders for help and guidance.In this article the term clergy is used instead of rabbi because many of the statements made are applicable to all clergy.     

Embeddability,syntax, and semantics in accounts of scientific theories

Recently several philosophers of science have proposed what has come to be known as the semantic account of scientific theories. It is presented as an improvement on the positivist account, which is now called the syntactic account of scientific theories. Bas van Fraassen claims that the syntactic account does not give a satisfactory definition of empirical adequacy and empirical equivalence. He contends that his own semantic account does define these notations acceptably, through the concept of embeddability, a concept which he claims cannot be defined syntactically. Here, I define a syntactic relation which corresponds to the semantic relation of embeddability. I suggest that the critical differences between the positivist account and van Fraassen's account have nothing to do with the distinction between semantics and syntax.     

The two faces of Quine's naturalism

Quine's naturalized epistemology is ambivalent between a modest naturalism according to which epistemology is an a posteriori discipline, an integral part of the web of empirical belief, and a scientistic naturalism according to which epistemology is to be conducted wholly within the natural sciences. This ambivalence is encouraged by Quine's ambiguous use of science, to mean sometimes, broadly, our presumed empirical knowledge and sometimes, narrowly, the natural sciences. Quine's modest naturalism is reformist, tackling the traditional epistemological problems in a novel way; his scientistic naturalism is revolutionary, requiring restriction and reconceptualization of epistemological problems. In particular, his scientistic naturalism trivializes the question of the epistemic standing of the natural sciences, whereas modest naturalism takes it seriously, and can offer a plausible answer.Earlier versions of this paper were read at the Moral Sciences Club, Cambridge, U.K., Temple University, and the University of Miami.

Proximal Peer-Level Effects of a Small-Group Selected Prevention on Aggression in Elementary School Children: An Investigation of the Peer Contagion Hypothesis

Examined peer contagion in small group, selected prevention programming over one school year. Participants were boys and girls in grades 3 (46 groups, 285 students) and 6 (36 groups, 219 students) attending school in low-resource, inner city communities or moderate resource urban communities. Three-level hierarchical linear modeling (observations within individuals within groups) indicated that individual change in aggression over time related to the average aggression of others in the intervention group. The individual child was pulled toward peers mean level of aggression; so the intervention appeared to reduce aggression for those high on aggression, and to make those low on aggression more aggressive. Effects appeared to be magnified in either direction when the child was more discrepant from his or her peers. From these results we derive a principle of discrepancy-proportional peer-influence for small group intervention, and discuss the implications of this for aggregating aggressive children in small group programs.     

Differences in Individual Approaches: Communication in the Familial Breast Cancer Consultation and the Effect on Patient Outcomes

This multicenter study aimed to assess (i) whether individual clinical geneticists and genetic counselors vary in their communication skills and (ii) whether this variation in communication impacts on patient outcomes, such as anxiety, depression, genetics knowledge, and satisfaction. One hundred and fifty women from high-risk breast cancer families attending their first genetic counseling consultation completed pre and post-consultation self-report questionnaires. The consultations were audiotaped and transcribed verbatim. Univariate analyses showed highly significant differences between individual clinical geneticists and genetic counselors in: facilitating understanding (p 0.001); facilitating active involvement (p 0.001); facilitating partnership building (p = 0.003); addressing emotional concerns (p 0.001); and discussing prophylactic mastectomy (p = 0.017). Multivariate linear regressions showed that this variation in communication resulted in a greater change in patients depression 4 weeks after the counseling session (p = 0.017). These findings suggest clinical geneticists and genetic counselors have achieved some standardization in communicating information, but showed diversity in their facilitation skills. Communication skills may be a useful area to explore further in this field.     

Myth-conceptions concerning death-related behavior

Summary The discussion here has suggested that it is likely that the following beliefs are myth conceptions: Living is always prefarable to dying. It is possible for people not to play God. We can be sure that what happens biologically is willed by God. God speaks to us only through our biology. Dying occurs only at one point in time-at the end of the terminal period. Death or dead are more accurate labels than passed on. Persons who are dying know without being told that they are dying. Biological death is the most important thing happening when a person dies.The goal of achieving understanding of our death-related behavior can be facilitated by recognition of myth-conceptions such as these and the previously identified myths the acceptance of which may have an impact upon both biological and mental or spiritual health of those involved.He is the author ofSociology of Death and other books and articles.     

Recognition and treatment of incestuous families

Incest is a major mental health problem, in terms of both prevalence and morbidity. Father-daughter incest constitutes the majority of reported cases. The possibility of incest should be considered in a family which includes a violent father, a disabled mother, a child in an adult maternal role, or an acting out adolescent girl. Intervention requires recognition of the criminal and addictive aspects of the father's behavior. Active cooperation between mental health professionals and mandated child protective and law enforcement agencies is necessary for effective treatment. Group therapy and affiliated self-help programs appear to be the treatment modality of choice. Rehabilitation of the family is based upon restoration of the mother-daughter bond as a guarantee of safety for the child.     

A longitudinal study of the marriage role expectations of college women: 1961–1984

The marriage role expectations of female university students enrolled in an introductory marriage and family course at the University of Kentucky in 1961 (N=72), 1972 (N=58), 1978 (N=115), and 1984 (N=81) were compared. The 1972 group was found to be significantly more egalitarian than the 1961 group in overall marriage role expectations and on all subscales except authority. The 1978 and 1984 groups were significantly more egalitarian than the 1961 group on overall marriage role expectations and on all seven of the subscales: authority, homemaking, child care, personal characteristics, social participation, education, and employment and support. The 1978 group was significantly more egalitarian than the 1972 group only on authority and homemaking, with no significant differences on the other five subscales or on overall role expectation score. The 1984 group was significantly more egalitarian than the 1972 group only on authority, homemaking, and child care, and was slightly (not satistically significant) more traditional on personal characteristics and social participation. There were no significant differences between the 1978 and 1984 groups on overall expectation or on any of the subscales. In fact, the 1984 group was slightly more traditional on homemaking, personal characteristics, social participation, employment and support, and overall expectations. The data from this study showed the greatest gain in egalitarian trends to be between 1961 and 1972, with a continuation of the trends at a somewhat slower rate of change between 1972 and 1978, and a discontinuation of the trend toward more egalitarian expectations between 1978 and 1984.The data were collected in February 1961, January 1972, September 1978, and September 1984. Special acknowledgement and appreciation are expressed to Jessie Ringo (retired), University of Kentucky, for making the 1961 data available for this study.     

Parental interpersonal perceptual style,child adjustment,and parent—Child interactions

This research examined relationships between parental interpersonal perceptual style (IPS)—the extent to which they are biased in their perceptions of children's behaviors—and (a) the adjustment of their own children and (b) parent-child interactions. In two studies, groups of parents first viewed a videotape of a male or female target child interacting with an adult in a playroom and then completed a behavior checklist about the target child that measured their IPS. In Study 1, parents' (especially fathers') IPS was found to be related to interaction between them and their 5-to7-year-old child; for example, the less negatively biased the father was, the more likely the child was to openly display antagonistic behavior toward his or her parents. In Study 2, fathers' (but not mothers') IPS was found to be related to the teacher- and peer-assessed level of psychosocial adjustment of their own third-grade child; fathers of problem children tended to be more negatively biased in their perceptions than were fathers of either adequate or highly adjusted children. Findings are discussed in terms of their implications for understanding the role that person perception processes play in family functioning and child development.This article is an adaptation of a paper presented as part of a symposium held during the 1977 meeting of the American Psychological Association.

The development of pretend language: Toward an understanding of the child's theory of mind

Is has been suggested that there exists a linkage between the mental representation of pretense, the acquisition of the cognitive internal state lexicon, and the development of theory of mind. Using an empirically derived taxonomy of pretend language, predictions derivable from such a relationship were tested. In three related studies, the pretend lexicons of 4 1/2- to 5-year-old children and the adults who interacted with them in home and school situations were examined for evidence of sophisticated pretend language use, for parallels in child and adult pretend language, and for connections between pretend and other mental state words. Results did not support the hypothesis that pretense and the language associated with it were linked to mental state language acquisition. However, the findings that are reported provide converging evidence for the claim that pretense in young children is a form of acting-as-if behaivor rather than a form of mental represetnational activity.     

The emotional impact of treating child abuse

The author agrees with the need for pastoral intervention in child abuse and neglect, but warns that pastors need to be prepared to handle the intense emotional effects that result. The emotional impact of treating child abuse and neglect is examined under the rubric countertransference. Three sources of countertransference are outlined: identification with the child, identification with the parent, and encountering resistance. Finally, ways to cope with countertransference engendered by treating child abuse and neglect are explored. The need for quality supervision is especially stressed.     

Children's knowledge of prepositional phrase structure: An experimental test

A test of prepositional phrase structure in 4- to 6-year-old children's language is reported. Children's productions of PP and verb-particle sequences were elicited. Children produced pronominal and full NP objects of sequences corresponding to PPs and verb-plus-particle in the adult grammar. Prepositions freely took both pronominal and full NP objects (He's jumping over it. He's jumping over the table). In particle verb constructions, pronominal objects were placed immediately after the verb in all but a few cases (He's pushing it overnot He's pushing over it). With full NP objects, the preference was to place the verb after the particle (He's pushing over the table). These facts support an analysis in which if the child constructs a PP-over-P—NP structure for prepositional phrases but not for verb-particle sequences, and follows adultlike rules for these structures.This research was supported in its initial stages by NIH grant No. HD90647-03 to T. Roeper and S.J. Keyser and was completed while the author was supported in part by grants from the Graduate School Research Committee of the University of Wisconsin-Madison and from the Spencer Foundation through the University of Wisconsin School of Education.     

Empirical bayes point estimates of latent trait scores without knowledge of the trait distribution

In this paper, recent developments in empirical Bayes procedures are tied in with current work in mental test theory. Point estimators of true scores are derived for the binomial and Rasch test models. These estimators are shown to be asymptotically optimal. Smoothing and an empirical study of the behavior of empirical Bayes estimates are taken up in the final section.This research was supported by the National Science Foundation, Division of Biological and Medical Sciences, Program in Psycho-Biology, Grant No. NSF GB-30779.     

Same-Gender Couple Therapy: Creating New Objects in Intimacy and Parenehood Transition

The formation of same-gender couple and parental relationships is described and analyzed from a combined relational and couple therapy. The parenthood transition of a homosexual couple into a family structure, that includes two biological parents and a stepfather, creates tremendous turbulence and crises. The couple link is transformed throughout critical and major changes from a two-ness unit into a four- one, which develops unique relationships with the mother and the baby. This paper presents how therapists can treat and intervene in both intra-psychic gender crises as well as inter-psychic breakdowns of the couple shared reality. The therapeutic processes highlight the transformative changes that the homosexual couple has to experience in order to accept the loss of previous accomplishments in gender identity and love relationships. In addition, therapy helps to disentangle co-joint couple objects while creating new shared spaces.Aviva Mazor, PhD, is at the Bob Shapell School of Social Work, Tel-Aviv University, Ramat-Aviv, Tel-Aviv, 69978, Israel (A-mazor@netvision.net.il).
