An asymmetric effect of relational integration on recognition memory

Two experiments assessed whether conceptual relations (e.g., contains: COOKIE JAR) facilitate the retrieval of concepts (e.g., COOKIE and JAR) from long-term memory. The CARIN model of nominal combination asserts that conceptual relations are represented with and selected from the modifier noun (COOKIE). Thus, the model predicts that relational integration will facilitate memory for modifiers but not for head nouns (JAR). In Experiment 1, concepts were studied in pairs and were then tested individually. Recognition accuracy was higher for modifiers than for head nouns. In Experiment 2, the studied concepts (e.g., COOKIE JAR) were tested in the context of a new pair that instantiated either the same relation (e.g., COOKIE plate) or a different relation (e.g., COOKIE crumb). Recognition was again better for modifiers than for head nouns, but only when the same conceptual relation was instantiated at both study and test. Thus, results indicate that conceptual relations (a) facilitate recognition memory, and (b) are associated more strongly with the modifier than with the head noun.     

The neural plasticity of other-race face recognition

Although it is well established that people are better at recognizing own-race faces than at recognizing other-race faces, the neural mechanisms mediating this advantage are not well understood. In this study, Caucasian participants were trained to differentiate African American (or Hispanic) faces at the individual level (e.g., Joe, Bob) and to categorize Hispanic (or African American) faces at the basic level of race (e.g., Hispanic, African American). Behaviorally, subordinate-level individuation training led to improved performance on a posttraining recognition test, relative to basic-level training. As measured by event-related potentials, subordinate- and basic-level training had relatively little effect on the face N170 component. However, as compared with basic-level training, subordinate-level training elicited an increased response in the posterior expert N250 component. These results demonstrate that learning to discriminate other-race faces at the subordinate level of the individual leads to improved recognition and enhanced activation of the expert N250 component.     

First-grade predictors of mathematical learning disability: A latent class trajectory analysis

Kindergarten to third grade mathematics achievement scores from a prospective study of mathematical development (n = 306) were subjected to latent growth trajectory analyses. The four corresponding classes included children with mathematical learning disability (MLD, 6% of sample), and low (LA, 50%), typically (TA, 39%) and high (HA, 5%) achieving children. The groups were administered a battery of intelligence (IQ), working memory, and mathematical-cognition measures in first grade. The children with MLD had general deficits in working memory and IQ and potentially more specific deficits on measures of number sense. The LA children did not have working memory or IQ deficits but showed moderate deficits on these number sense measures and for addition fact retrieval. The distinguishing features of the HA children were a strong visuospatial working memory, a strong number sense, and frequent use of memory-based processes to solve addition problems. Implications for the early identification of children at risk for poor mathematics achievement are considered.     

The MCMI-III personality disorders scores predicted by the NEO-FFI-R and the ZKPQ-50-CC: a comparative study

This study was designed to compare the NEO-FFI-R versus the ZKPQ-50-CC in their relationships with the fourteen MCMI-III personality disorder scales in a Spanish non-clinical sample (N = 674). Previous studies showed consistent relationships between the Five Factor Model and the DSM-IV personality disorders (PD), but there is no comparative study between both Five Factor and Zuckerman's personality models. The aim was to replicate previous results about relationships between the Big-Five and PDs using the revised short version of the NEO-PI-R, and to compare the NEO-FFI-R versus the ZKPQ-50-CC regarding the relationships with MCMI-III personality disorder scales. Results showed no sharp differences between the NEO-FFI-R and ZKPQ-50-CC scales. Each instrument explained around 30% of the PDs MCMI-III scales variance. Using conjointly the 10 personality scales from the NEO-FFI-R and ZKPQ-50-CC, the PDs accounted variance rose to 38%. Differences and similarities between both short personality questionnaires are discussed.     

Keeping up impressions: Inferential rules for impression change across the Big Five

Not all first impressions have equal longevity. Which kinds of impression have the greatest mobility—downward and upward—over the course of acquaintanceships? In this article, we propose an inferential account of impression maintenance across Big Five trait domains. With data from field and laboratory studies, we provide evidence that positive impressions of agreeableness (A), conscientiousness (C), and emotional stability (ES) are especially vulnerable to small amounts of contrary evidence, whereas positive first impressions of extraversion (E) and openness (O) are more resistant to contrary information. Impressions of E and O demonstrated minimal susceptibility to negativity effects in a longitudinal study of college roommate impressions (Study 1), in a study of perceivers’ implicit theories about different trait domains (Study 2), and in an experimental study of manipulated impression change (Study 3).     

Mock juror's perceptions of a child witness passing or failing a truth and lies discussion or promising to tell the truth

This study examined the effect of a child passing or failing the UK truth and lies discussion (TLD) compared with the Canadian promise to tell the truth on mock jurors' decisions regarding witness credibility and truthfulness and defendant guilt. Ninety-two participants read a vignette that described a child witnessing his father physically attacking his mother. The vignette was manipulated for witness age (age 4 years and age 8 years) and TLD performance/promise. Supporting the hypotheses, participants rated the witness's credibility and truthfulness significantly higher after a witness passed a TLD and after promising to tell the truth. The age of the child witness did not significantly affect jurors' decision making. The results are discussed in relation to arguments regarding the abolition of the UK's TLD in favour of introducing a promise to tell the truth.     

“I think you understand me.” Studying the associations between actual,assumed, and perceived understanding within couples

The current study examined the associations between actual, assumed, and perceived understanding and partners’ levels of dyadic adjustment. One hundred fifty-two couples provided questionnaire data (assumed and perceived understanding), participated in a videotaped conflict interaction, and in a video-review task to assess actual understanding (empathic accuracy). The data were analyzed by means of the Actor-Partner Interdependence Model. The results suggest that (a) some aspects of how well someone assumes that (s)he has understood the partner during a preceding conflict interaction were positively associated with his/her own objective level of understanding (actor effect), (b) that someone's perception of how understood (s)he feels was not associated with the partner's objective level of understanding (partner effect), and (c) perceived understanding, but not actual understanding, was positively associated with dyadic adjustment.     

Why did I buy this? Consumers' post‐impulse‐consumption experience and its impact on the propensity for future impulse buying behaviour

This paper advances research into impulse buying by examining how this behaviour is reinforced/curtailed, highlighting the primary role of the post‐purchase experience in encouraging future impulse buying behaviour. Extant research emphasizes the role of the purchase experience, that is, psychological benefits attained from the impulse purchase experience itself, as a reinforcer of impulse buying. Conversely, this paper uses experiments to demonstrate that it is the post‐purchase experience, not the purchase experience, that reinforces or curtails future impulse buying. Indeed, irrespective of the valence of the purchase experience, a negative post‐purchase experience (whereby a product or service is found to have limited use/does not deliver expected benefits) results in post‐purchase regret, which in turn curtails future impulse buying. In contrast, a positive post‐purchase experience reinforces impulse buying. This research also demonstrates that consumers utilize three types of coping mechanisms to mitigate post‐purchase regret, that is, planful problem solving, positive reinterpretation, or mental disengagement. However, although the use of planful problem solving curtails future impulse buying, use of the other two mechanisms results in behaviour reinforcement. These findings have several important implications for both marketers and consumers, which the authors discuss in detail.
