The application of anticipatory avoidance learning to the treatment of homosexuality. 3. The sexual orientation method

A questionnaire technique of assessing the relative levels of homo- and hetero-erotic orientation has been constructed as part of a research project on the treatment of homosexuality by anticipatory avoidance learning. In the construction and scoring of this, the authors have borrowed from the semantic differential and personal questionnaire techniques. The technique, termed the Sexual Orientation Method (S.O.M.), is fully described and data are presented on internal consistency, uni-dimensionality, reliability and validity. The S.O.M. is intended as a quick and reasonably accurate quantitative method of assessing the response to treatment of patients known to be homosexual, and not as a method of detecting homosexuality in those not otherwise presenting with it. Applications of the scale to the assessment of changes due to treatment of sexual deviations other than homosexuality are readily possible.     

Information along contours and object boundaries

F. Attneave (1954) famously suggested that information along visual contours is concentrated in regions of high magnitude of curvature, rather than being distributed uniformly along the contour. Here the authors give a formal derivation of this claim, yielding an exact expression for information, in C. Shannon's (1948) sense, as a function of contour curvature. Moreover, they extend Attneave's claim to incorporate the role of sign of curvature, not just magnitude of curvature. In particular, the authors show that for closed contours, such as object boundaries, segments of negative curvature (i.e., concave segments) literally carry greater information than do corresponding regions of positive curvature (i.e., convex segments). The psychological validity of this informational analysis is supported by a host of empirical findings demonstrating the asymmetric way in which the visual system treats regions of positive and negative curvature.     

An fMRI study on conceptual, grammatical, and morpho-phonological processing

The aim of the present study was to determine whether processing of syntactic word information (lemma) is subserved by the same neural substrate as processing of conceptual or word form information (lexeme). We measured BOLD responses in 14 native speakers of German in three different decision tasks, each focussing specifically on one level of lexical processing (conceptual, syntactic, and morpho-phonological). The test parameters were natural gender, grammatical gender, and word form derivation, respectively. Discrimination between words played backwards and complex sounds served as control task. Complex contrasts revealed a functional fractionation of the left inferior frontal gyrus for each level of lexical processing.     

African American college women's suicide buffers

African American women have lower suicide rates than other women and men in the United States They may possess suicide buffers including social support, religiosity, negative attitudes regarding suicide acceptability, and African American culture. To examine the relationships buffers may have with suicide ideation, 300 African American female college students completed measures of suicide ideation and buffers. Three variables accounted for a significant and unique portion of the variance in suicide ideation: family support, a view that suicide is unacceptable, and a collaborative religious problem-solving style. The identification of these factors may help in the assessment, prevention, and intervention of suicide for African American women and other women and men.     

Morphological priming: the role of prime duration, semantic transparency, and affix position.

Patterns of facilitation in three lexical decision studies reveal several properties of morphologically complex words that influence processing. In one study, effects of morphological (VOWED-VOW) similarity are contrasted with effects of either semantic (PLEDGE-VOW) or orthographic (VOWEL-VOW) similarity at two prime durations to show the distinctiveness of morphological processing. In a second study, we compare morphologically complex forms that are semantically transparent (CASUALLY-CASUALNESS) with opaque forms (CASUALTY-CASUALNESS) and show that opaque relatives are more similar to VOWEL-VOW type pairs than to transparent relatives. In the third study, we examine facilitation for complex targets (CALCULATION) preceded by prefixed (MISCALCULATE) and suffixed (CALCULATOR) relatives and show that the position of the base morpheme influences processing under cross-modal but not under purely visual presentation conditions. Taken collectively, under comparable presentation conditions, semantic transparency but not base morpheme position constrains morphological processing.     

Ethnicity and Social Support During Pregnancy

Data from two multi-ethnic prospective studies of African American, Latina, and non-Hispanic White pregnant women were used to examine the influence of contextual factors on social support processes during pregnancy. Multiple types of support (perceived support, received support, support satisfaction, network support) and sources of support (baby's father, family, friends) were assessed. The role of ethnicity in social support was examined after controlling for the contribution of related contextual factors (SES, marital status, age, parity, employment) to these processes. The impact of ethnicity and related contextual factors differed across sources of social support. Ethnic differences in support from family and friends, but not from the baby's father, emerged. However, marital status was a consistent predictor of support from the baby's father, and SES was a consistent predictor of support from friends. Overall, the findings of two studies suggest that although ethnicity is associated with support from friends and family, other contextual factors, such as marital status and SES, influence support processes during pregnancy.     

The contribution of morphological and semantic relatedness to repetition priming at short and long lags: Evidence from hebrew

The effect of morphological repetition at lag 0 and at lag 15 on lexical decision was investigated in Hebrew with three types of relation between prime and target. In the semantic-plus-morphological condition (SM), the prime and the target in each pair were two semantically related derivatives of the same root. In the “pure morphological” condition (M), the prime and the target derived from the same root, but their semantic association was very low, or nonexistent. In the semantic priming condition (S), primes and targets were semantically associated but were not morphologically related. The pure semantic relationship produced a significant facilitation at lag 0 that disappeared completely at lag 15. The pure morphological relation produced (smaller but) significant facilitation at lag 0 that was not attenuated at lag 15. When prime and target were semantically as well as morphologically related, the facilitation at lag 0 was similar to semantic priming, whereas at lag 15 it was similar to the pure morphological effect. Significant repetition effects at both lags were also found with non-words that shared the same (nonsensical) root and differed with respect to real derivational affixes. The differential time course for facilitation due to semantic and morphological relatedness suggests distinct underlying processes, although at lag 0 it is possible that semantic relatedness may augment the morphological repetition effect. Morphological repetition probably facilitates the retrieval of lexical information that, under certain circumstances, is necessary for lexical decision.     

An indigenous community mental health service on the Tohono O'odham (Papago) Indian reservation: Seventeen years later

The status of a fully indigenous mental health program serviced and controlled by the Tohono O'odham (Papago) Indian tribe is reviewed from the perspective of its 17-year history. The program functions in large measure in a crisis intervention model, with suicidal or acutely disturbed cases being most frequent. However, a whole range of disorders and ages are seen. Traditional Medicine Men and Women are often used as consultants, as are some professionals. In recent years child sex abuse and abuse of drugs among youth are prominent problems. The program experienced problems of obtaining services off reservations for patients in need, and in establishing credibility of the Indian Mental Health workers with the outside service providers.
