Dissociating the generation stage in implicit and explicit memory tests: Incidental production can differ from strategic access

An assumption of the generate/recognize model of direct and indirect memory is that the generation stage is identical on explicit and implicit tests. Two experiments were conducted to examine the generation stage by requiring subjects to write down every word-stem solution they could generate on either an implicit test, a cued-recall test, or a generate/recognize test. In Experiment 1, the subjects studied words and anagrams; target generation was not significantly different on the three tests. However, in Experiment 2, the subjects studied the target words with a context word, and saw either thesame ordifferent context with the test stem. Now the generation stages dissociated, such that the context manipulation had no significant effect on the implicit test, but on the cued-recall test, more targets were generated with the same context words than were generated with different context words. The results argue against the claim that dissociations between implicit and explicit tests are due only to the addition of recognition processes on the explicit test, because the generation processes themselves can be dissociated.     

Infertility treatment for postmenopausal patients: an equity-based approach

This article examines two questions pertaining to the extension of infertility treatment to postmenopausal women. First, what concepts and principles of infertility practice apply to assisted reproduction for the postmenopausal patient? Second, what role should these concepts play in the development of an ethical justification for extending women's reproductive lives past the menopausal boundary? The argument offered here supports their claim to infertility services on the basis of the formal principle of justice, which requires that similar cases be treated similarly. The cases of many postmenopausal patients are argued to be relevantly similar to classes of patients who already receive assistance in reproduction.     

Prenatal gender preference of mothers of feminine and masculine boys: Relation to sibling sex composition and birth order

A mother's (prenatal) wish for a girl has, at times, been implicated as an etiological factor for boyhood femininity or its DSM-III-R diagnostic equivalent, the Gender Identity Disorder of Childhood. In one sample of 52 feminine and 52 nonclinical control boys from Los Angeles, the proportion of mothers who recalled a wish for a girl during the pregnancy did not differ significantly between groups (26.9% vs. 19.2%, respectively); however, in both groups, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. In a second sample of 103 feminine boys from Toronto, the maternal wish for a girl was significantly higher than that found in the Los Angeles sample (43.7% vs. 26.9%), but a control group was not available; as in the Los Angeles sample, the maternal wish for a girl was significantly more common in sibships in which all of the proband's older siblings were male. Implications of these findings for further study of maternal influences on boyhood femininity are discussed.     

Transracial adoption: Questions on heritage for parents,children and counsellors

The placement of black children in white families in the US and UK once constituted the majority of transracial adoptions. This is reflected in much of the research to date, and the (sometimes negative) findings continue to influence policy and practice. More recently, in Asia and Latin America, need and demand have led to a relaxation of intercountry adoption laws. Transracial adoptions by Caucasian parents are increasing in number and type; questions about how to facilitate adjustment must be readdressed. These parents of transracially adopted children face the task of striking a balance between racial awareness and cultural integration. Most want to protect their adoptive child's sense of self using knowledge of biological family and county of origin but, at the same time, they must settle the child into a new, sometimes alien, community. This paper provides guidelines for counselling all transracially adoptive families who are concerned about adjustment, but particular reference is made to questions on heritage raised by Caucasian parents of Asian children.     

College Students' Perceptions of the Relationship Between Fee and Counseling

Fee as a variable that could have an impact on college students' perceptions of counseling was explored because of the authentic concerns about college counseling centers needing to charge direct fees for their services. Participants (N = 350) represented a cross-section of potential consumers of psychological services, not just individuals currently receiving services. On an overt level, fees seemed to be less influential in counseling considerations, but were taken into account on a more covert level. This study supports the psychological literature, which suggests that fee is not the most important factor in clients' decisions to seek counseling. Implications for counselors, administrators, researchers, and program planners are discussed.     

Harmonic,melodic, and frequency height influences in the perception of multivoiced music

Two experiments addressed the influences of harmonic relations, melody location, and relative frequency height on the perceptual organization of multivoiced music. In Experiment 1, listeners detected pitch changes in multivoiced piano music. Harmonically related pitch changes and those in the middle-frequency range were least noticeable. All pitch changes were noticeable in the high-frequency voice containing the melody (the most important voice), suggesting that melody can dominate harmonic relations. However, the presence of upper partials in the piano timbre used may have accounted for the harmonic effects. Experiment 2 employed pure sine tones, and replicated the effects of Experiment 1. In addition, the influence of the high-frequency melody on the noticeability of harmonically related pitches was lessened by the presence of a second melody. These findings suggest that harmonic, melodic, and relative frequency height relationships among voices interact in the perceptual organization of multivoiced music.     

Do locally defined feature discontinuities capture attention?

Results from previous visual search studies have suggested that abrupt onsets produce involuntary shifts of attention (i.e., attentional capture), but discontinuities in simple features such as color and brightness do not (Jonides & Yantis, 1988). In the present study we tested whether feature discontinuities (i.e., “singletons”) can produce attentional capture in a visual search task if defined “locally” or over a small spatial range. On each trial, a variable number of letters appeared, one of which differed from the others in color or intensity. The location of this singleton was uncorrelated with target location. Local discontinuities were created by embedding the letters in a dot texture. In Experiment 1, display size effects for singleton targets were not reduced with the addition of a background dot texture. Similar results were obtained in Experiment 2, regardless of variations in texture density. Experiment 3 confirmed that when targets are defined by a color or intensity singleton, they are detected preattentively, and that increasing texture density yields faster detection. We conclude that the spatial range over which feature discontinuities are defined may influence the guidance of spatial attention, but it has no influence on their ability to capture attention.     

Intuitive Perceptions of Decision-making Strategy: Naive Assessors' Concepts of Integrative Complexity

Although there are measurable differences in integrative complexity among solutions that individuals generate in dealing with problems, it is uncertain to what extent people comprehend, recognize, and have preferences among different levels of complexity. Integrative complexity is a function of differentiation (the perception of several attributes within, or perspectives about, a topic) and integration (combining the differentiated characteristics in an interactive or synthesizing solution). The current paper reports two experiments dealing with how university students perceive, interpret, and choose among solutions differing in complexity. Experiment 1 showed that subjects accurately rated the complexity of described solutions differing along the continuum, but that their assessment of their own responses differed from the results of expert scoring. Their self-estimated complexity was highly correlated with their preferences, and preferred complexity was reliably higher than either expert- or self-assessed complexity of subject-generated solutions. Subjects were able to hypothesize quite accurately about environmental and endogenous factors likely to affect complexity. Experiment 2 found that in response to problem scenarios, solutions selected as being potentially most effective were consistently more complex than solutions that participants considered themselves most likely to use. The idea of complexity seems to be intuitively recognizable and understandable by untrained subjects: They can and do distinguish among problem solutions (self-generated or presented) that vary on that dimension, and are able to assess accurately the effects of relevant variables. Such subjects also share the bias shown by experts in favour of the superiority of more complex approaches.
