The encoding-retrieval relationship: retrieval as mental simulation

There is increasing evidence to suggest that mental simulations underlie many cognitive processes. We review results from three rapidly developing research areas suggesting that simulations underlie information retrieval. First, neuroimaging work indicates that cortical circuits that were activated during encoding are reactivated during retrieval. Second, retrieval is aided by behavioural re-enactment of processes involved in encoding, including re-enactment of encoding eye movements. Third, the time courses of encoding of visual features and the retrieval of information about those features are related. Overall, the evidence suggests that the often observed interactions between encoding and retrieval result from a cognitive system that, at least partially, reactivates processes that were involved in encoding to retrieve information.     

Motivated prediction of future feelings: effects of negative mood and mood orientation on affective forecasts

This article examines the role of motivational factors in affective forecasting. The primary hypothesis was that people predict positive emotional reactions to future events when they are motivated to enhance their current feelings. Three experiments manipulated participants' moods (negative vs. neutral) and orientation toward their moods (reflective vs. ruminative) and then assessed the positivity of their affective predictions for future events. As hypothesized, when participants adopted a reflective orientation, and thus should have been motivated to engage in mood-regulation processes, they predicted more positive feelings in the negative than in the neutral mood condition. This pattern of mood-incongruent affective prediction was not exhibited when participants adopted a ruminative orientation. Additionally, within the negative mood condition, generating affective forecasts had a more positive emotional impact on reflectors than on ruminators. The findings suggest that affective predictions are sometimes driven by mood-regulatory motives.     

Our inalienable ability to sin: Peter Olivi’s rejection of asymmetrical freedom

From the time of Augustine to the late thirteenth century, leading Christian thinkers agreed that freedom requires the ability to make good choices, but not the ability to make bad ones. If freedom required the ability to sin, they reasoned, neither God nor the angels nor the blessed in heaven could be free. This essay examines the work of Peter Olivi, the first medieval philosopher known to reject the asymmetrical conception of freedom. Olivi argues that the ability to sin is essential to creaturely freedom and remains even in heaven. While Anselm is the nominal target of Olivi’s arguments on this topic, they form part of a wider critique directed even more at Aquinas and his followers. Olivi faults them for misunderstanding the nature of the created will and for failing to provide a foundation for a particular kind of moral responsibility: personal merit.     

Brain potentials implicate temporal lobe abnormalities in criminal psychopaths

Psychopathy is associated with abnormalities in attention and orienting. However, few studies have examined the neural systems underlying these processes. To address this issue, the authors recorded event-related potentials (ERPs) while 80 incarcerated men, classified as psychopathic or nonpsychopathic via the Hare Psychopathy Checklist--Revised (R. D. Hare, 1991, 2003), completed an auditory oddball task. Consistent with hypotheses, processing of targets elicited larger frontocentral negativities (N550) in psychopaths than in nonpsychopaths. Psychopaths also showed an enlarged N2 and reduced P3 during target detection. Similar ERP modulations have been reported in patients with amygdala and temporal lobe damage. The data are interpreted as supporting the hypothesis that psychopathy may be related to dysfunction of the paralimbic system--a system that includes parts of the temporal and frontal lobes.     

The Gap Between Clinical Trial and Application in Health Behavior Counseling: Can Behavioral Medicine Build a Bridge?

Patients desire to have information about health-related behaviors (e.g., exercise) provided to them by their health care provider. Outcomes of clinical trials in physical activity counseling are modest at best and therefore, the degree of effectiveness of physical activity counseling in the primary care setting remains unclear. We describe what may be considered a real-world example of behavior change counseling aimed at primary or secondary risk factor identification and modification for CHD in women. We examined rates of baseline and follow-up physical activity in our sample of midlife Caucasian and African American women (N = 227) participating in a hospital-based CHD-risk screening. Baseline physical activity levels and rates of return for follow-up appointments were quite low with only negligible achievement of behavior change recommendations. In light of these findings, the potential role of behavioral medicine in training and collaboration with health care providers in primary care behavior counseling is discussed.

Unconscious affective reactions to masked happy versus angry faces influence consumption behavior and judgments of value

The authors explored three properties of basic, unconsciously triggered affective reactions: They can influence consequential behavior, they work without eliciting conscious feelings, and they interact with motivation. The authors investigated these properties by testing the influence of subliminally presented happy versus angry faces on pouring and consumption of beverage (Study 1), perception of beverage value (Study 2), and reports of conscious feelings (both studies). Consistent with incentive motivation theory, the impact of affective primes on beverage value and consumption was strongest for thirsty participants. Subliminal smiles caused thirsty participants to pour and consume more beverage (Study 1) and increased their willingness to pay and their wanting more beverage (Study 2). Subliminal frowns had the opposite effect. No feeling changes were observed, even in thirsty participants. The results suggest that basic affective reactions can be unconscious and interact with incentive motivation to influence assessment of value and behavior toward valenced objects.     

Realism and Uncertainty of Unobservable Common Causes in Factor Analysis

Famously, scientific theories are underdetermined by their evidence. This occurs in the factor analytic model (FA), which is often used to connect concrete data (e.g. test scores) to hypothetical notions (e.g. intelligence). After introducing FA, three general topics are addressed. (i) Underdetermination: the precise reasons why FA is underdetermined illuminates various claims about underdetermination, abduction, and theoretical terms. (ii) Uncertainties: FA helps distinguish at least four kinds of uncertainties. The prevailing practice, often encoded in statistical software, is to ignore the most difficult kinds, which are essential to FA's underdetermination. (iii) What to do: some suggestions for dealing with these hardest types of uncertainty are offered.
