Examining the contributions of desirable difficulty and reminding to the spacing effect

Although substantial evidence indicates that spacing repeated study events with intervening material generally enhances memory performance relative to massing study events, the mechanism underlying this benefit is less clear. Two experiments examined the role of reminding difficulty during the acquisition of material in modulating final memory performance for spaced repetitions utilizing recognition (Experiment 1) and recall tests (Experiment 2). Specifically, participants studied a list of words presented one or two times separated by one or five items. On each trial participants reported whether the item had been previously presented (i.e., repetition detection judgment), and the response latency served as a proxy for reminding difficulty such that longer response latencies reflected more difficult reminding. A third experiment extended this paradigm with the inclusion of a massed condition and novel lag conditions (three and ten items). Results revealed significant lag effects in final test performance across experiments despite comparable repetition detection difficulty between lag conditions during acquisition. Moreover, results from within-participant point-biserial analyses and mediation analyses converged on overall performance measures in suggesting that repetition detection difficulty failed to modulate final test performance in the current paradigm. Discussion considers the implications of the current results for mechanisms proposed to underlie the benefits of spaced study and spaced retrieval practice.     

Embodied metaphor and the “true” self: Priming entity expansion and protection influences intrinsic self-expressions in self-perceptions and interpersonal behavior

Drawing on conceptual metaphor perspectives and embodied cognition theories, we proposed that the intrinsic self-concept-who people think they truly are-is represented metaphorically as a physical entity, and that expressions of the intrinsic self-concept are therefore conceptualized in terms of entity activity. Using an empirical strategy for experimentally investigating conceptual metaphor, we tested whether exposure to pictorial primes depicting entity expansion and protection produces metaphor-consistent effects on self-perceptions and interpersonal behaviors expressive of the intrinsic self-concept. In Study 1, participants primed with entity expansion perceived themselves as more self-actualized and less concerned with satisfying extrinsic contingencies of self-esteem. Study 2 showed that this effect was mediated by the increased accessibility of the concept entity expansion. In Study 3, expansion-primed participants conformed less to other people's opinions. In Study 4, participants primed with entity protection were less willing to disclose intimate, but not non-intimate, self-knowledge to a stranger.     

The curious case of the refrigerator-TV: similarity and hybridization

This article examines the role of similarity in the hybridization of concepts, focusing on hybrid products as an applied test case. Hybrid concepts found in natural language, such as singer songwriter, typically combine similar concepts, whereas dissimilar concepts rarely form hybrids. The hybridization of dissimilar concepts in products such as jogging shoe mp3 player and refrigerator TV thus poses a challenge for understanding the process of conceptual combination. It is proposed that models of conceptual combination can throw light on the judged future success and desirability of hybrid products in general. The composite prototype model proposes two stages of conceptual combination. In the first stage, the concepts are aggregated into an additive hybrid, simply by forming the union of the two sets of attributes. In the second stage, any conflicting attributes are identified and resolved, often with the introduction of emergent attributes, resulting in an integrative hybrid. Across four studies that varied the similarity and type of hybrid products, similar and integrative hybrids were valued more than dissimilar and additive hybrids. Critically, though, dissimilar hybrids were also highly valued if they were integrative. Results supported the two stages proposed by the composite prototype model, and implications for other models of hybrid formation are discussed.     

Integrative and semantic relations equally alleviate age-related associative memory deficits

Two experiments compared effects of integrative and semantic relations between pairs of words on lexical and memory processes in old age. Integrative relations occur when two dissimilar and unassociated words are linked together to form a coherent phrase (e.g., horse-doctor). In Experiment 1, older adults completed a lexical-decision task where prime and target words were related either integratively or semantically. The two types of relation both facilitated responses compared to a baseline condition, demonstrating that priming can occur in older adults with minimal preexisting associations between primes and targets. In Experiment 2, young and older adults completed a cued recall task with integrative, semantic, and unrelated word pairs. Both integrative and semantic pairs showed significantly smaller age differences in associative memory compared to unrelated pairs. Integrative relations facilitated older adults' memory to a similar extent as semantic relations despite having few preexisting associations in memory. Integratability of stimuli is therefore a new factor that reduces associative deficits in older adults, most likely by supporting encoding and retrieval mechanisms.     

The dynamics of consumer behavior: A goal systemic perspective

Like most behavior, consumer behavior too is goal driven. In turn, goals constitute cognitive constructs that can be chronically active as well as primed by features of the environment. Goal systems theory outlines the principles that characterize the dynamics of goal pursuit and explores their implications for consumer behavior. In this vein, we discuss from a common, goal systemic, perspective a variety of well known phenomena in the realm of consumer behavior including brand loyalty, variety seeking, impulsive buying, preferences, choices and regret. The goal systemic perspective affords guidelines for subsequent research on the dynamic aspects of consummatory behavior as well as offering insights into practical matters in the area of marketing.     

A dual-process model of brand extension: Taxonomic feature-based and thematic relation-based similarity independently drive brand extension evaluation

The success of a brand extension depends largely on the similarity between the brand and its extension product. Recent psychological and neuroscientific evidence supports a dual-process model that distinguishes taxonomic feature-based similarity from thematic relation-based similarity. In addition to providing a parsimonious organizational framework for prior brand extension research, this dual-process model also provides novel predictions about the processing and evaluation of taxonomic brand extensions (e.g., Budweiser cola) and thematic brand extensions (e.g., Budweiser chips). Results indicate that taxonomic and thematic similarities independently contribute to branding professionals' and lay consumers' evaluations of real and hypothetical brand extensions (Studies 1A and 1B). Counter-intuitively, thematic brand extensions are processed more rapidly (Study 2), judged more novel, and evaluated more positively than taxonomic extensions (Study 3). When induced to consider the commonalities between the brand and the extension product, however, taxonomic extensions are judged more novel and evaluated more positively (Study 3). Implications for brand extension and marketing more generally are discussed.     

Searching for two things at once: Establishment of multiple attentional control settings on a trial-by-trial basis

Recent work has demonstrated that attention can be configured to multiple potential targets in spatial search. However, this previous work relied on a fixed set of targets across multiple trials, allowing observers to offload attentional control settings to longer-term representations. In the present experiments, we demonstrate multiple attentional control settings that operate independently of space (Experiments 1 and 2). More important, we show that observers can be cued to different control settings on a trial-by-trial basis (Experiment 3). The latter result suggests that observers were capable of maintaining multiple control settings when the demands of the task required an attentional search for specific feature values. Attention can be configured to extract multiple feature values in a goal-directed manner, and this configuration can be can be dynamically engaged on a trial-by-trial basis. These results support recent findings that reveal the high precision, complexity, and flexibility of attentional control settings.     

Predicting premeditation: future behavior is seen as more intentional than past behavior

People's intuitions about the underlying causes of past and future actions might not be the same. In 3 studies, we demonstrate that people judge the same behavior as more intentional when it will be performed in the future than when it has been performed in the past. We found this temporal asymmetry in perceptions of both the strength of an individual's intention and the overall prevalence of intentional behavior in a population. Because of its heightened intentionality, people thought the same transgression deserved more severe punishment when it would occur in the future than when it did occur in the past. The difference in judgments of both intentionality and punishment was partly explained by the stronger emotional reactions that were elicited in response to future actions than in response to past actions. We consider the implications of this temporal asymmetry for legal decision making and theories of attribution more generally.     

Competitive victimhood as a response to accusations of ingroup harm doing

Accusations of unjust harm doing by the ingroup threaten the group's moral identity. One strategy for restoring ingroup moral identity after such a threat is competitive victimhood: claiming the ingroup has suffered compared with the harmed outgroup. Men accused of harming women were more likely to claim that men are discriminated against compared with women (Study 1), and women showed the same effect when accused of discriminating against men (Study 3). Undergraduates engaged in competitive victimhood with university staff after their group was accused of harming staff (Study 2). Study 4 showed that the effect of accusations on competitive victimhood among high-status group members is mediated by perceived stigma reversal: the expectation that one should feel guilty for being in a high-status group. Exposure to a competitive victimhood claim on behalf of one's ingroup reduced stigma reversal and collective guilt after an accusation of ingroup harm doing (Study 5).
