Rhesus monkeys (Macaca mulatta) and capuchin monkeys (Cebus apella) remember future responses in a computerized task

Planning is an important aspect of many daily activities for humans. Planning involves forming a strategy in anticipation of a future need. However, evidence that nonhuman animals can plan for future situations is limited, particularly in relation to the many other kinds of cognitive capacities that they appear to share with humans. One critical aspect of planning is the ability to remember future responses, or what is called prospective coding. Two monkey species (Macaca mulatta and Cebus apella) performed a series of computerized tasks that required encoding a future response at the outset of each trial. Monkeys of both species showed competence in all tests that were given, providing evidence that they anticipated future responses and that they appropriately engaged in those responses when the time was right for such responses. In addition, some tests demonstrated that monkeys even remembered future responses that were not as presently motivating as were other aspects of the task environment. These results indicated that monkeys could anticipate future responses and retain and implement those responses when appropriate.     

Mock Jurors’ Perception of Stalking: The Impact of Gender and Expressed Fear

Two experiments investigated mock-juror perceptions of intimate stalking using Kentucky’s (United States) anti-stalking legislation. Experiment 1 used a mock-juror methodology in which 177 undergraduates (87 men and 90 women) from a large southeastern US university read a stalking trial summary and rendered individual judgments as mock jurors. The main research question of Experiment 1 was how participant gender impacted trial judgments (e.g., verdict) when the gender of both the defendant and victim were manipulated. Overall, the results showed that men rendered significantly fewer guilty verdicts than women, particularly in conditions that included the prototypical type of intimate stalking (female victim/male defendant). In Experiment 2, also using a mock-juror methodology, 129 undergraduates (51 men and 78 women) from a large southeastern U.S. university read a stalking trial summary (involving a female victim and male defendant) and rendered individual judgments as mock jurors. The main research question of Experiment 2 focused on whether victim fear (high or low) impacted trial judgments (e.g., verdict). The results yielded an interaction of participant gender and victim fear. Specifically, whereas different levels of fear did not impact women, men yielded fewer guilty verdicts in the low victim fear condition compared to the high victim fear condition. The results of the present experiments are discussed in terms of the implications of stalking allegations brought to trial.     

Cognitive mechanisms of false facial recognition in older adults

Older adults show elevated false alarm rates on recognition memory tests involving faces in comparison to younger adults. It has been proposed that this age-related increase in false facial recognition reflects a deficit in recollection and a corresponding increase in the use of familiarity when making memory decisions. To test this hypothesis, we examined the performance of 40 older adults and 40 younger adults on a face recognition memory paradigm involving three different types of lures with varying levels of familiarity. A robust age effect was found, with older adults demonstrating a markedly heightened false alarm rate in comparison to younger adults for "familiarized lures" that were exact repetitions of faces encountered earlier in the experiment, but outside the study list, and therefore required accurate recollection of contextual information to reject. By contrast, there were no age differences in false alarms to "conjunction lures" that recombined parts of study list faces, or to entirely new faces. Overall, the pattern of false recognition errors observed in older adults was consistent with excessive reliance on a familiarity-based response strategy. Specifically, in the absence of recollection older adults appeared to base their memory decisions on item familiarity, as evidenced by a linear increase in false alarm rates with increasing familiarity of the lures. These findings support the notion that automatic memory processes such as familiarity remain invariant with age, while more controlled memory processes such as recollection show age-related decline.     

Evaluating the valence of remembered events: the importance of age and self-relevance

We examined the role of self-relevance in older and younger adults' evaluations of remembered events. In Study 1, participants rated the positivity of their own positive, negative and neutral memories as well as those of a same-aged peer. Older adults rated events more positively than younger adults did, regardless of the memory source. In Study 2, we showed that this age difference is not due to differences in the valence of the events that older and younger adults reported. This effect appears to reflect the more positive mindset of older people, rather than an intention to regulate emotions associated with personal experiences. Finally, there was one effect for self relevance: Regardless of age, participants rated their own remembered events as more emotionally intense than those of a same aged peer.     

Fast thought speed induces risk taking

In two experiments, we tested for a causal link between thought speed and risk taking. In Experiment 1, we manipulated thought speed by presenting neutral-content text at either a fast or a slow pace and having participants read the text aloud. In Experiment 2, we manipulated thought speed by presenting fast-, medium-, or slow-paced movie clips that contained similar content. Participants who were induced to think more quickly took more risks with actual money in Experiment 1 and reported greater intentions to engage in real-world risky behaviors, such as unprotected sex and illegal drug use, in Experiment 2. These experiments provide evidence that faster thinking induces greater risk taking.     

From neural responses to population behavior: neural focus group predicts population-level media effects

Can neural responses of a small group of individuals predict the behavior of large-scale populations? In this investigation, brain activations were recorded while smokers viewed three different television campaigns promoting the National Cancer Institute's telephone hotline to help smokers quit (1-800-QUIT-NOW). The smokers also provided self-report predictions of the campaigns' relative effectiveness. Population measures of the success of each campaign were computed by comparing call volume to 1-800-QUIT-NOW in the month before and the month after the launch of each campaign. This approach allowed us to directly compare the predictive value of self-reports with neural predictors of message effectiveness. Neural activity in a medial prefrontal region of interest, previously associated with individual behavior change, predicted the population response, whereas self-report judgments did not. This finding suggests a novel way of connecting neural signals to population responses that has not been previously demonstrated and provides information that may be difficult to obtain otherwise.     

Sources of Uncertainty About Daughters’ Breast Cancer Risk that Emerge During Genetic Counseling Consultations

Uncertainty is central to the experience of genetic decision making and counseling about cancer risk. Women seeking genetic counseling about their breast cancer risk may experience a great deal of uncertainty about issues related to their daughters. We used a theory of Communication and Uncertainty Management to guide analysis of sources of uncertainty about daughters that emerged during 16 video-recorded and transcribed conversations between mothers at risk for a BRCA 1/2 mutation and their genetic healthcare practitioners. An interpretive design and constant comparative method revealed three dominant patterns or themes representing sources of uncertainty mothers have relating to their daughters: disease risk, future cancer screening, and communication of related information to daughters. Both practitioners and mothers discussed these aspects of uncertainty. The findings identify the significant role uncertainty and familial concerns play in mothers’ genetic testing decision making process. To assist genetic practitioners, we highlight daughter-related concerns that mothers are uncertain about and which are vital to their genetic counseling needs.     

Cultivating admiration in brands: Warmth,competence, and landing in the “golden quadrant”

Although a substantial amount of research has examined the constructs of warmth and competence, far less has examined how these constructs develop and what benefits may accrue when warmth and competence are cultivated. Yet there are positive consequences, both emotional and behavioral, that are likely to occur when brands hold perceptions of both. In this paper, we shed light on when and how warmth and competence are jointly promoted in brands, and why these reputations matter.
