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.     

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.     

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     

Object-based attention overrides perceptual load to modulate visual distraction

The ability to ignore task-irrelevant information and overcome distraction is central to our ability to efficiently carry out a number of tasks. One factor shown to strongly influence distraction is the perceptual load of the task being performed; as the perceptual load of task-relevant information processing increases, the likelihood that task-irrelevant information will be processed and interfere with task performance decreases. However, it has also been demonstrated that other attentional factors play an important role in whether or not distracting information affects performance. Specifically, object-based attention can modulate the extent of distractor processing, leaving open the possibility that object-based attention mechanisms may directly modulate the way in which perceptual load affects distractor processing. Here, we show that object-based attention dominates perceptual load to determine the extent of task-irrelevant information processing, with distractors affecting performance only when they are contained within the same object as the task-relevant search display. These results suggest that object-based attention effects play a central role in selective attention regardless of the perceptual load of the task being performed.     

What's in a baby-cry? Locationist and constructionist frameworks in parental brain responses

Parental brain responses to baby stimuli constitute a unique model to study brain-basis frameworks of emotion. Results for baby-cry and picture stimuli may fit with both locationist and psychological constructionist hypotheses. Furthermore, the utility of either model may depend on postpartum timing and relationship. Endocrine effects may also be critical for accurate models to assess mental health risk and treatment.     

Born in the USA: how immigrant generation shapes meritocracy and its relation to ethnic identity and collective action

Endorsing meritocracy can make low-status group members more accepting of inequality. This study examined whether rejecting meritocracy is related to increased ethnic identification among Latino immigrants, and whether identity in turn is related to increased support for collective action. We hypothesize that these relationships depend upon immigrant generation. A survey was conducted with 184 first- and second-generation Latino immigrants in New York City. Second-generation Latinos endorsed meritocracy less than those in the first generation, at least in part because they perceived that other Americans viewed their group in a less positive light (i.e., lower public regard). Further, meritocracy was negatively linked to ethnic identity and, through it, support for collective action among the second generation. Among the first generation, meritocracy was not related to ethnic identity and was positively related to support for collective action. We discuss the implications of growing up near the bottom of the U.S. social hierarchy for ethnic identity and collective action.     

Social Constraints on the Direct Perception of Emotions and Intentions

In this paper, we first review recent arguments about the direct perception of the intentions and emotions of others, emphasizing the role of embodied interaction. We then consider a possible objection to the direct perception hypothesis from social psychology, related to phenomena like ‘dehumanization’ and ‘implicit racial bias’, which manifest themselves on a basic bodily level. On the background of such data, one might object that social perception cannot be direct since it depends on and can in fact be interrupted by a set of cultural beliefs. We argue, however, that far from threatening the idea of direct perception, these findings clearly contradict the idea of hardwired theory of mind modules. More generally, we suggest that in order to further the understanding of social cognition we must take seriously insights about in-group and out-group distinctions and related phenomena, all of which are currently neglected in the mainstream social cognition literature.     

Nonwork orientations relative to career: A multidimensional measure

Although scholars typically assess an individual's nonwork role orientation relative to career as a unitary construct, we argue that a person's orientation toward nonwork roles is multi-dimensional. Drawing on a literature review demonstrating the need for improved constructs capturing changing relationships between career and multi-faceted nonwork orientations, and empirical data from three studies with samples at different career stages (early and mid-career), we use factor analysis and data from qualitative and longitudinal studies to develop three unique scales to assess a person's nonwork priorities relative to career orientations: family, personal life, and community service. There were generally positive relationships between the protean career scales and the new nonwork role orientation measures. Future research should move beyond a binary work–life or work–family models and include multi-dimensional measures of nonwork orientations relative to career.     

The impact of Relative Prevalence on dual-target search for threat items from airport X-ray screening

The probability of target presentation in visual search tasks influences target detection performance: this is known as the prevalence effect (Wolfe et al., 2005). Additionally, searching for several targets simultaneously reduces search performance: this is known as the dual-target cost (DTC: Menneer et al., 2007). The interaction between the DTC and prevalence effect was investigated in a single study by presenting one target in dual-target search at a higher level of prevalence than the other target (Target A: 45% Prevalence; Target B: 5% Prevalence). An overall DTC was found for both RTs and response accuracy. Furthermore, there was an effect of target prevalence in dual-target search, suggesting that, when one target is presented at a higher level of prevalence than the other, both the dual-target cost and the prevalence effect contribute to decrements in performance. The implications for airport X-ray screening are discussed.
