How do I remember that I know you know that I know?

Communication is aided greatly when speakers and listeners take advantage of mutually shared knowledge (i.e., common ground). How such information is represented in memory is not well known. Using a neuropsychological-psycholinguistic approach to real-time language understanding, we investigated the ability to form and use common ground during conversation in memory-impaired participants with hippocampal amnesia. Analyses of amnesics' eye fixations as they interpreted their partner's utterances about a set of objects demonstrated successful use of common ground when the amnesics had immediate access to common-ground information, but dramatic failures when they did not. These findings indicate a clear role for declarative memory in maintenance of common-ground representations. Even when amnesics were successful, however, the eye movement record revealed subtle deficits in resolving potential ambiguity among competing intended referents; this finding suggests that declarative memory may be critical to more basic aspects of the on-line resolution of linguistic ambiguity.     

The Perceived Prayers of Others,Stress, and Change in Depressive Symptoms Over Time

The purpose of this study was to see if believing that others are praying for them reduces the noxious effect of living in a rundown neighborhood on change in depressive symptoms among older people. Findings from a longitudinal nationwide survey of older adults reveal that the deleterious effect of living in a dilapidated neighborhood on depressive symptoms is significantly reduced for older individuals who believe others often pray for them. Further analyses suggest that the stress-buffering properties of beliefs about being prayed for by others remain virtually unchanged after emotional support from family members and close friends is taken into account. The findings have potentially important implications for studying church-based prayer groups as well as assessing the ways in which individuals might support each other during difficult times.     

Reported Contact with the Dead, Religious Involvement, and Death Anxiety in Late Life

The purpose of this study is to examine the relationship between contact with the dead and death anxiety. The data come from an ongoing nationwide survey of older adults. A conceptual model is developed that contains the following theoretical linkages: (1) making contact with the dead instills a deeper appreciation of the connection that exists among all people; (2) this fundamental sense of connectedness with others fosters a deeper sense of religious meaning in life; and (3) individuals with a deeper sense of religious meaning in life are less likely to experience feelings of death anxiety than people who have not been able to find meaning in life through religion. The findings from this study provide support for each of these relationships. The theoretical implications of these hypotheses are discussed.     

How do habits guide behavior? Perceived and actual triggers of habits in daily life

What are the psychological mechanisms that trigger habits in daily life? Two studies reveal that strong habits are influenced by context cues associated with past performance (e.g., locations) but are relatively unaffected by current goals. Specifically, performance contexts—but not goals—automatically triggered strongly habitual behaviors in memory (Experiment 1) and triggered overt habit performance (Experiment 2). Nonetheless, habits sometimes appear to be linked to goals because people self-perceive their habits to be guided by goals. Furthermore, habits of moderate strength are automatically influenced by goals, yielding a curvilinear, U-shaped relation between habit strength and actual goal influence. Thus, research that taps self-perceptions or moderately strong habits may find habits to be linked to goals.     

Examining the factor structure of the Hare Self-Report Psychopathy Scale

The 64-item Hare Self-Report Psychopathy Scale (Hare SRP; Paulhus, Neumann, & Hare, in press ) is the most recent revision of the SRP, which has undergone numerous iterations. Little research has been conducted with this new edition; therefore, the goal of this study was to elucidate the factor structure as well as the criterion-related, convergent, and discriminant validity of the measure in a large sample of college students (N = 602). Confirmatory factor analyses revealed that the best fitting model was the original 4-factor model proposed by the authors of the Hare SRP (compared to a 1-factor, 2-factor, and 4-factor random model). The 4-factor model revealed superior fit for the data relative to the other alternative models. In addition, we elaborated on the psychometric properties of this 4-factor model in this sample. The Hare SRP total and factor scores evidenced good internal reliability as well as promising criterion-related, convergent, and discriminant validity in terms of predicting scores on conceptually relevant external criteria. Implications for theory and future research are discussed.     

Wolves in sheep’s clothing: How and when hypothetical questions influence behavior

How and when does responding to hypothetical questions shape future judgment and behavior? We identify knowledge accessibility as an implicit process through which hypothetical questions influence individuals, and examine moderators of accessibility that determine when these effects obtain. In an initial study, we show that hypothetical questions increase the accessibility of the specific positive or negative knowledge referenced by the question. In five subsequent studies, we manipulate factors known to enhance (consistency, elaboration) and attenuate (awareness, delay) accessibility, and show that these factors moderate the influence of hypothetical questions on individuals’ voting choices, legal decision-making, and consumption behavior.     

Relations among age, visual memory, and resting cerebral metabolism in 40 healthy men

Visual memory, as measured by the Benton Visual Retention Test (BVRT), and resting regional cerebral metabolic rates for glucose (rCMRglc), as measured by positron emission tomography (PET) and [18-F]fluorodeoxyglucose, were examined in 40 very healthy men, aged 21 to 83 years. Age-related differences in visual memory were found but were significantly smaller than differences reported in the general population. This discrepancy is attributable to our rigorous health screening. The age-related differences found in this sample are estimates of the lower limit of population differences unconfounded by disease. Age-related differences on undistracted delayed visual memory were greater than differences on immediate visual memory, suggesting age-related differences in spontaneous elaborative visual information processing. No relation between visual memory and resting rCMRglc was found, supporting the hypothesis that mental abilities are unrelated to resting brain metabolism unless both functions are influenced by disease.     

“If They Notice I’m Mexican”: Narratives of Perceived Discrimination from Individuals Who Crossed the U.S.-Mexico Border at Ports of Entry

ABSTRACT

Understanding individuals’ encounters with Customs and Border Protection (CBP), the largest law enforcement agency in the United States, is an important theoretical and policy-relevant issue. Travelers entering the U.S. through ports of entry may generalize their experiences with border officials to local law enforcement, and thus, negative experiences at ports of entry may reduce travelers’ willingness to cooperate with police and report victimization. Existing studies, however, have primarily examined unauthorized border crossings rather than travelers’ port of entry experiences. This study uses grounded theory and qualitative data to explore the perceptions and experiences of 191 young adults who discussed how individuals are treated when crossing the U.S.-Mexico border at land ports of entry. Findings show that participants reported perceptions and experiences of discrimination based on physical appearances, language differences, and nationality. Participants also described border officials engaging in routine law enforcement behaviors, including poor policing practices.
