College students' memory for vocabulary in their majors: evidence for a nonlinear relation between knowledge and memory.

The effect of domain knowledge on students' memory for vocabulary terms was investigated. Participants were 142 college students (94 education majors and 48 business majors). The measure of domain knowledge was the number of courses completed in the major. Students recalled three different lists (control, education, and business) of 20 words. Knowledge effects were estimated controlling for academic aptitude, academic achievement, and general memory ability. Domain-specific knowledge consistently predicted recall, above and beyond the effect of these control variables. Moreover, nonlinear models better represented the relation between knowledge and memory, with very similar functions predicting recall in both knowledge domains. Specifically, early in the majors more classes corresponded with increased memory performance, but a plateau period, when more classes did not result in higher recall, was evident for both majors. Longitudinal research is needed to explore at what point in learning novices' performance begins to resemble experts' performance.     

Fishing For Feelings? Hooking Viewers Helps!

To better understand individual variation in emotional responses to advertising, the authors recommend considering 3 general factors: characteristics of the individual who sees the ad, characteristics of the ad itself, and the nature of the ad–individual interface. This article examines 1 aspect of the individual, affect intensity (AI); one aspect of the ad, the degree to which the ad tells a story; and 1 aspect of the ad–individual interface, whether the individual is hooked by the ad. Experimental results reveal that an individual's being hooked by an ad has a positive relation with upbeat and warm feelings, a negative relation with disinterested feelings, and significantly enhances the viewer's attitude toward the ad. We find that AI has a positive relation with upbeat and warm feelings, and AI moderates the effect of being hooked on upbeat and warm feelings. Findings also reveal that narrative ad structure has a positive relation with upbeat and warm feelings, a negative relation with disinterested feelings, and that being hooked moderates the effect of narrative ad structure on upbeat and warm feelings responses.     

Everyday Problem Solving: Experience, Strategies, and Behavioral Intentions

Experience and strategic flexibility predict performance on solving hypothetical everyday problems, although their relation to real-world behavior is largely unknown (e.g., M. Diehl, S. L. Willis, & K. W. Schaie, 1995). Moreover, few studies have examined highly salient, rare-event problems such as relocation decisions. This study tested whether experience and strategic flexibility, in addition to demographic variables, were related to intentions to relocate. Ninety-five adults (M age = 72.1 years) completed problem-solving vignettes, provided information regarding previous experience with problems related to living arrangements, and stated personal relocation intentions. Logistic regression analyses showed that both experience (Odds Ratio (OR) = 40.6) and the number of strategies generated (OR= 3.0) were significantly associated with an increased likelihood of considering a late-life relocation. The benefits of linking lab-based assessments of everyday problem solving to real-world behavior are discussed.     

Calvin, Osiander and Participation in God

Abstract: This article investigates the ways in which Calvin's controversy with Osiander has made the Reformed tradition skittish when confronted with categories of participation. An examination of the similarities between Calvin and Osiander are probed, with an eye to seeing how the debate functioned in refining Calvin's doctrine of participation whose strict trinitarian boundaries kept creature and Creator distinct.     

When Social Accounts Backfire: The Exacerbating Effects of a Polite Message or an Apology on Reactions to an Unfair Outcome1

We examined the effects of ex ante polite or apologetic messages on an individual's responses to a low (unfair) outcome offered in an ultimatum (take‐it‐or‐leave‐it) situation. Results show that these 2 messages (a) increased, rather than decreased, participants' perceptions of unfairness; and (b) decreased, rather than increased, their acceptance of the outcome. Moreover, participants engaged in more punishing behaviors when the outcome was accompanied by either of the messages than when no account was provided. Further analysis revealed that perceived manipulative intent mediated participants' reactions to the polite message and to the apology. These results indicate that if a message seems insincere and manipulative, it can exacerbate an individual's negative reactions to an unfair outcome accompanying the message.     

Coping With Uncertainty: Superstitious Strategies and Secondary Control1

The aim of the present studies was to investigate the relationship between primary and secondary control and the use of superstitious strategies under conditions of uncertainty and stress. In the first study, 78 participants completed a chance‐determined card‐guessing task in which they were permitted to use a psychic's card selections instead of making their own card selections. Participants' use of a superstitious strategy (a psychic's selections) increased significantly with the perceived likelihood of failure, regardless of belief in psychic ability. A second study (N= 102) replicated these findings using a skill task. Overall, these data suggest that as the need to control outcomes becomes increasingly salient, the use of superstitious strategies may represent attempts at secondary control.     

Reinforcer quality matters: A test of the Mathematical Principles of Reinforcement with domestic hens (Gallus gallus domesticus)

This study evaluated the ability of Killeen's (1994) Mathematical Principles of Reinforcement to account for the effects of changes in reinforcer quality on hens' rates of responding on fixed‐ratio schedules. Hens were trained to peck a key on a fixed‐ratio schedule of reinforcement and then experienced an ascending series of ratio values in two separate conditions. In different conditions, the food reinforcer was either wheat or puffed wheat. Response rates initially increased with increases in ratio requirement before eventually decreasing at larger ratios. Quantitative fits of the model accounted for the data well. The fits revealed that different foods were systematically associated with changes in the specific activation parameter, a, and these were consistent with previous reports of preference for those food items.     

Vantage perspective in analogue trauma memories: an experimental study

Vantage perspective during recall is thought to affect the emotionality and accessibility of distressing memories. This study aimed to test the effects of vantage perspective during recall on memory associated distress and intrusion development. An adapted version of the trauma film paradigm was used in an experimental design with three conditions. Participants were asked to listen to eyewitness reports of car accidents (e.g. Trauma Analogue Induction) and imagine the scenes vividly using mental imagery. Afterwards, they were asked to recall the most distressing scene from field perspective, observer perspective, or to recall a neutral image from observer perspective (control condition) (e.g. Trauma Analogue Recall). Recall from field perspective resulted in higher negative mood, state-anxiety, and a higher number of short-term intrusions compared to the observer perspective condition and control condition. Negative mood and state-anxiety were mediators in the relationship between vantage perspective and intrusions. In comparison to observer perspective, field perspective increased the amount of short-term intrusions as a result of higher levels of negative mood and state-anxiety after memory retrieval. Future research on the interaction between vantage perspective at recall and negative mood and anxiety effects is warranted.     

Intoxicated eyewitnesses: The effect of a fully balanced placebo design on event memory and metacognitive control

Few studies have examined the impact of alcohol on metacognition for witnessed events. We used a 2 × 2 balanced placebo design, where mock witnesses expected and drank alcohol, did not expect but drank alcohol, did not expect nor drank alcohol, or expected but did not drink alcohol. Participants watched a mock crime in a bar‐lab, followed by free recall and a cued‐recall test with or without the option to reply “don't know” (DK). Intoxicated mock witnesses' free recall was less complete but not less accurate. During cued‐recall, alcohol led to lower accuracy, and reverse placebo participants gave more erroneous and fewer correct responses. Permitting and clarifying DK responses was associated with fewer errors and more correct responses for sober individuals; and intoxicated witnesses were less likely to opt out of erroneous responding to unanswerable questions. Our findings highlight the practical and theoretical importance of examining pharmacological effects of alcohol and expectancies in real‐life settings.
