Memory for lateral asymmetries in well-known faces: Evidence for configural information in memory representations of Faces

Two Experiments Were Carried Out To Determine Whether Configural Information About The Left-Right Organization Of A Face Is Represented In Memory. In Experiment 1, Subjects Consistently Chose Normal (Correct) Photographs as Better Likenesses of Familiar Faces than Mirror-Reversed photographs. This Effect Was Stronger For More Familiar Faces, and Did Not Depend On the Presence of Asymmetric Hairstyles Or Single, Asymmetrically Located Features (E.G., Moles, Warts). In Experiment 2, Subjects Were Asked To Decide Which of the Left and Right Composite Faces Was a Better Likeness of the Person. The Left Composite Is Normally Considered a Better Likeness In Perceptual Matching Tasks Where The Normal Photograph Is Present. Left Composites Were Regarded As Better Likenesses than Right Composites, Despite the Fact That This Bias Appeared To Compete With One in Favor of the More Realistic of the two Composites. The Results of Experiments 1 And 2 Suggest That Configural Information About The Left-Right Organization Of Faces Is Represented In Memory. The Right Hemiface Of A Familiar Face Was Considered More Expressive Than The Left Hemiface. This Is Opposite To The Normal Result for Unfamiliar Faces. The Implications of the Results For Models Of Face Representations and for Future Research Directions Are Discussed.     

Normative data for semantically associated Spanish word lists that create false memories

The present study provides norms for Spanish word lists that have been used to create false memories in native speakers of Spanish. The word lists reported are based on the Roediger and McDermott (1995) lists that have been used extensively to examine illusory memories. We employed Roediger and McDermott’s critical lures, translated them into Spanish, and created semantically associated Spanish word lists by testing native Spanish speakers. The resulting lists were then normed with additional native Spanish speakers. Overall, the participants recalled 53% of the list items and 32% of the critical lures with the word lists developed. In addition, 74% of the list items and 69% of the critical lures were recognized by the participants. The present study adds to the literature by providing a set of Spanish lists that can be used by researchers interested in evaluating false memories in individuals who speak Spanish.

Oral contraceptive use among African American adolescents: Individual and community influences

Side effects of oral contraceptives are a noteworthy problem, particularly among low-income young women who reside in inner-city communities. The problem may be compounded by inadequate family planning services, particularly when such services are provided by general medical practices with high volumes of clients. This study examined the prevalence and correlates of pill-related side effects, with particular attention to the role of clinic characteristics. Participants were 177 pregnant and parenting African American adolescents and young women (average age=18.34). The experience of a pill-related side effect was the most frequently cited barrier to birth control use, and it was significantly related to contraceptive behavior. Finally, although participants attending comprehensive clinics experienced more barriers to medical service use than those attending neighborhood clinics, they reported fewer problems with pill-related side effects and better psychological functioning. Implications for future research and policy are discussed. This study was completed with the assistance of grants from the Illinois Department of Alcoholism and Substance Abuse, the National Institute of Child Health and Human Development, and the Office of Research on Women's Health to Jean Rhodes. Portions of this paper were presented at the 1993 Biennial Meeting of the Society for Community Research and Action, Williamsburg, Virginia.

Distinctiveness and expertise effects with homogeneous stimuli: towards a model of configural coding

Recent studies using Brennan's computerized caricature generator have demonstrated distinctiveness effects consistent with the idea that faces are coded in terms of their individual distinctive properties. Based on these findings it is suggested that, for homogeneous classes whose members share a common configuration, distinctive configural information may be coded as metric deviations from a spatial norm. Experiments are described which demonstrate similar distinctiveness effects in bird identification. Transformations that increase distinctiveness (caricatures) produced faster identification and a higher recognition proportion, for both experts and nonexperts, than transformations that reduce distinctiveness (anticaricatures). This distinctiveness advantage is consistent with the norm-based coding idea. Furthermore, within certain limits, increasing distinctiveness did not impair performance relative to that for veridical drawings. For experts there was also a caricature advantage, such that 50% caricatures of birds in a highly homogeneous and familiar class (passerines) were identified more quickly, provided that they were recognized at all, than uncaricatured veridical drawings. The significance of a caricature advantage for the visual coding of configural information is discussed.     

THE SENSE OF THE BEAUTIFUL AND APOPHATIC THOUGHT: EMPIRICAL BEING AS IKON

This essay is an interdisciplinary study of beauty that attempts to bridge the gap between religion/theology and science in some measure by drawing from Dionysius the Areopagite (c. 500) a notion of being that I argue is consonant with the notion of the sense of the beautiful, which I develop using Steven Weinberg's and Werner Heisenberg's discussions of empirical beauty. I use the term ikon to refer concisely to Dionysius' theophanic notion of being, namely, that the beyond‐being is nonsubstantially present in being.     

The own-age bias in face recognition: a meta-analytic and theoretical review

A large number of studies have examined the finding that recognition memory for faces of one's own age group is often superior to memory for faces of another age group. We examined this own-age bias (OAB) in the meta-analyses reported. These data showed that hits were reliably greater for same-age relative to other-age faces (g = 0.23) and that false alarms were reliably less likely for same-age compared with other-age faces (g = -0.23). Further meta-analyses of measures of signal detection demonstrated that, although no difference in response criterion was evident (g = -0.01), discriminability was reliably better for same-age compared with other-age faces (g = 0.37). As well, children, younger adults, and older adults exhibited superior discriminability for same-age compared with other-age age faces. Thus, the OAB appears to be a robust effect that influences the accuracy of face recognition. Theoretical accounts of the OAB have generally suggested that it reflects more extensive, recent experiences with one's own age group relative to other-age groups. Additional analyses were supportive of this account as the OAB was present even for groups (e.g., older adults) that had prior experiences as members of another age group. However, the most comprehensive account of the OAB will also likely invoke mechanisms suggested by social-cognitive theories.     

The Test of Time in School-Based Mentoring: The Role of Relationship Duration and Re-Matching on Academic Outcomes

The influence of match length and re-matching on the effectiveness of school-based mentoring was studied in the context of a national, randomized study of 1,139 youth in Big Brothers Big Sisters programs. The sample included youth in grades four through nine from diverse racial and ethnic backgrounds. At the end of the year, youth in intact relationships showed significant academic improvement, while youth in matches that terminated prematurely showed no impact. Those who were re-matched after terminations showed negative impacts. Youth, mentor, and program characteristics associated with having an intact match were examined. Youth with high levels of baseline stress and those matched with college student mentors were likely to be in matches that terminated prematurely, while rejection-sensitive youth and mentors who had previous mentoring experience were more likely to be in intact relationships. Implications for research and practice are discussed.     

Multiple bases for young and older adults' judgments of learning in multitrial learning

Prior work has suggested that participants use a memory-for-past-tests (MPT) heuristic for judgments of learning (JOLs) in a multitrial learning scenario. That is, when learning the same material in multiple sessions, previous memory performance can be used as a basis for later memory predictions. We explored this issue by evaluating the impact of healthy aging on the use of MPT across trials. Young adults and healthy older adults learned pairs of words, made JOLs, and received a memory test in three study-test trials on the same material. Results indicated that both young and older adults relied on MPT as a basis for JOLs and changes in MPT across trials were nominal. Further, only the most-recent past test influenced JOLs, whereas earlier tests were unrelated to later judgments. JOLs were also influenced by prior-trial JOLs and were related to subsequent memory performance on the same trial. We suggest that these data support both indirect- and direct-memory mechanisms as the bases for the MPT heuristic. Further, in a multitrial learning scenario, in which the same information was being learned, young and older adults used the same bases for their JOLs.
