Grounding the figure: Surface attachment influences figure-ground organization

We investigated whether the lower region effect on figure-ground organization (Vecera, Vogel, & Woodman, 2002) would generalize to contextual depth planes in vertical orientations, as is predicted by a theoretical analysis based on the ecological statistics of edges arising from objects that are attached to surfaces of support. Observers viewed left/right ambiguous figure-ground displays that occluded middle sections of four types of contextual inducers: two types of attached, receding, vertical planes (walls) that used linear perspective and/or texture gradients to induce perceived depth and two types of similar trapezoidal control figures that used either uniform color or random texture to reduce or eliminate perceived depth. The results showed a reliable bias toward seeing as “figure” the side of the figure-ground display that was attached to the receding depth plane, but no such bias for the corresponding side in either of the control conditions. The results are interpreted as being consistent with the attachment hypothesis that the lower region cue to figure-ground organization results from ecological biases in edge interpretation that arise when objects are attached to supporting surfaces in the terrestrial gravitational field.     

Flashbulb memories for September 11th can be preserved in older adults

Flashbulb memories (FMs) are vivid, long-lasting memories for the source of surprising, arousing news. Laboratory studies have consistently found that older adults, especially those with below-average frontal lobe (FL) function, are impaired in source memory relative to young. We tested memory for the source of news concerning the September 11th terrorist attacks in older adults with high or low frontal lobe function and in young people. We found no age differences in source memory a year after the event and no differences related to FL function. Flashbulb memories may be different from usual cases of source memory because of their emotional content, personal importance, or social relevance.     

Risk perceptions, worry, and attitudes about genetic testing for breast cancer susceptibility

This study assessed the unique associations of risk perceptions and worry with attitudes about genetic testing for breast cancer susceptibility. Women (general practitioner clinic attenders, university students, and first-degree relatives of breast cancer survivors; N?=?303) read information about genetic testing and completed measures assessing perceived cancer risk, cancer worry, and genetic testing attitudes and beliefs. Worry was associated with greater interest in genetic testing, stronger beliefs that testing has detrimental emotional consequences, and positive beliefs about benefits of testing and risk-reducing surgeries. Perceived risk was unrelated to interest and associated with more skeptical beliefs about emotional consequences and benefits of testing and risk-reducing surgeries. At low worry levels, testing interest increased with more positive beliefs about testing benefits; at high worry levels, interest was high regardless of benefits beliefs. The findings support Leventhal's Common-Sense Model of self-regulation delineating interactive influences of risk-related cognitions and emotions on information processing and behavior.     

Knowing your place: self-perceptions of status in face-to-face groups

Status is the prominence, respect, and influence individuals enjoy in the eyes of others. Theories of positive illusions suggest that individuals form overly positive perceptions of their status in face-to-face groups. In contrast, the authors argue that individuals' perceptions of their status are highly accurate--that is, they closely match the group's perception of their status--because forming overly positive status self-perceptions can damage individuals' acceptance in a group. Therefore, the authors further argue that individuals are likely to refrain from status self-enhancement to maintain their belongingness in a group. Support for their hypotheses was found in 2 studies of status in face-to-face groups, using a social relations model approach (D. A. Kenny & L. La Voie, 1984). Individuals showed high accuracy in perceiving their status and even erred on the side of being overly humble. Moreover, enhancement in status self-perceptions was associated with lower levels of social acceptance.     

Figure-ground assignment in pigeons: evidence for a figural benefit

Four pigeons discriminated whether a target spot appeared on a colored figural shape or on a differently colored background by first pecking the target and then reporting its location: on the figure or the background. We recorded three dependent variables: target detection time, choice response time, and choice accuracy. The birds were faster to detect the target, to report its location, and to learn the correct response on figure trials than on background trials. Later tests suggested that the pigeons might have attended to the figural region as a whole rather than using local properties in performing the figure-background discrimination. The location of the figural region did not affect figure-ground assignment. Finally, when 4 other pigeons had to detect and peck the target without making a choice report, no figural advantage emerged in target detection time, suggesting that the birds' attention may not have been automatically summoned to the figural region.     

Preschoolers' extension of familiar adjectives

In two experiments, we examined the role of labels in guiding preschoolers' extension of three types of familiar adjectives: emotional state adjectives, physiological state adjectives, and trait adjectives. On each trial, we labeled a target animal with one of the three different types of adjectives and asked whether these terms could apply to a subordinate-level match, a basic-level match, a superordinate-level match, or an inanimate object. In Experiment 1, participants extended trait adjectives, but not emotional or physiological adjectives, to members of the same basic-level category, regardless of whether an explicit basic-level label was provided for the target animal. Similarly, children in Experiment 2 also extended trait adjectives to the members of the same basic-level category, even when explicit superordinate- and subordinate-level labels were provided for the target animals. Together, these results demonstrate that children appreciate that emotional and physiological adjectives cannot be generalized to the same extent as can trait adjectives, and the results document the privileged status of basic-level categories in preschoolers' extension of trait adjectives.     

Are over a third of foster parent molestations homosexual?

50% of foster parent abuse in a general population survey and 34% of abuse as determined by the Illinois DCFS was homosexual. In news stories in the 50 largest newspapers and wire services 1980-2003, 175 foster parents sexually abused 351+ charges. For the 169 whose sex of victim could be determined: 149 (88%) were men; 76 (53%) victimized homosexually; and 85 (50%) were unmarried. Men assaulted 319 (91%) victims, homosexual practitioners 222 (63%), and the unmarried 164 (47%). From 1980-1994 57% of the victims were girls; after 1994 56% were boys. In 21 group homes, the molestation was homosexual in 15 (71%) and 31 of the 32+ perpetrators were male and at least 334 of 349+ victims were boys.     

Child molestations by homosexual foster parents: Illinois, 1997--2002

Do those who engage in homosexuality disproportionately sexually abuse foster or adoptive children as reported by child protective services? Illinois child services reported sexual abuse for 1997 through 2002. 270 parents committed "substantiated" sexual offenses against foster or subsidized adoptive children: 67 (69%) of 97 of these mother and 148 (86%) of 173 of these father perpetrators sexually abused girls; 30 (31%) of the mothers and 25 (14%) of the father perpetrators sexually abused boys, i.e., 92 (34%) of the perpetrators homosexually abused their charges. Of these parents 15 both physically and sexually abused charges: daughters by 8 of the mothers and 4 of the fathers, sons by 3 of the mothers, i.e., same-sex perpetrators were involved in 53%. Thus, homosexual practitioners were proportionately more apt to abuse foster or adoptive children sexually.     

Exploring the relationship between students’ values and the values of postsecondary institutions

Little is known of how institutional and individual value systems are related among university undergraduates. With three different measures and samples of college students, perceptions of university mission and values (i.e., institutional values, creating pro-social climates, and developing a life-long commitment to values) loaded independently of their personal values systems, and often negatively with social desirability. Perceptions of institutional values were generally independent of personal value systems, using either a rank-order (Sample 1, n = 199) or rating scale method (Sample 2, n = 107), or by focusing on moral behavior structures (Sample 3, n = 208). Together, these results indicate that higher education assessment may reflect institutional values that are independent of student personal value systems.Portions of this paper were presented at the 2004 Institute for College Student Values, Tallahassee, FL
