Memories of yesterday’s emotions: Does the valence of experience affect the memory-experience gap?

Intense pain is often exaggerated in retrospective evaluations, indicating a possible divergence between experience and memory. However, little is known regarding how people retrospectively evaluate experiences with both pleasant and unpleasant aspects. The Day Reconstruction Method (DRM; Kahneman. Krueger, Schkade, Schwarz, & Stone, 2004b) provides a unique opportunity to examine memory-experience gaps in recollections of individual days, which elicit a wide gamut of emotions. We asked female participants (N = 810, Study 1, and N = 615, Study 2) to reconstruct episodes of the previous day using the DRM and demonstrated that memory and experience diverge for both pleasant and unpleasant emotions. When they rated their day overall in a retrospectively evaluative frame of mind, the participants recalled more unpleasant and pleasant emotions than they reported feeling during the individual episodes, with a larger gap for unpleasant emotions than for pleasant emotions. The findings suggest that separate processes are used for committing positive and negative events to memory and that, especially when unpleasant emotions are involved, prudence is favored over accuracy.

The work of psychologists in the U.S. Intelligence community.

This reviews articles in a special issue (Civiello, 2009) of the Consulting Psychology Journal: Practice and Research on applications of psychology in the U.S. intelligence and military contexts. It identifies some common themes of the articles, as well as provides individual critiques of them. In general, the reviewer notes that the articles focus more on the current and desired state conditions than on the strategies, process, and mechanisms that might have been employed to obtain those desired states. This suggests that embedded psychologists might adopt a socio-technical-structural systems perspective and attempt to expand their specialized roles to include consulting on organizational change.

Aging, hearing acuity, and the attentional costs of effortful listening.

A dual-task interference paradigm was used to investigate the effect of perceptual effort on recall of spoken word lists by young and older adults with good hearing and with mild-to-moderate hearing loss. In addition to poorer recall accuracy, listeners with hearing loss, especially older adults, showed larger secondary task costs while recalling the word lists even though the stimuli were presented at a sound intensity that allowed correct word identification. Findings support the hypothesis that extra effort at the sensory–perceptual level attendant to hearing loss has negative consequences to downstream recall, an effect that may be further magnified with increased age.

Syllables and bigrams: Orthographic redundancy and syllabic units affect visual word recognition at different processing levels.

Over the last decade, there has been increasing evidence for syllabic processing during visual word recognition. If syllabic effects prove to be independent from orthographic redundancy, this would seriously challenge the ability of current computational models to account for the processing of polysyllabic words. Three experiments are presented to disentangle effects of the frequency of syllabic units and orthographic segments in lexical decision. In Experiment 1 the authors obtained an inhibitory syllable frequency effect that was unaffected by the presence or absence of a bigram trough at the syllable boundary. In Experiments 2 and 3 an inhibitory effect of initial syllable frequency but a facilitative effect of initial bigram frequency emerged when manipulating 1 of the 2 measures and controlling for the other in Spanish words starting with consonant-vowel syllables. The authors conclude that effects of syllable frequency and letter-cluster frequency are independent and arise at different processing levels of visual word recognition. Results are discussed within the framework of an interactive activation model of visual word recognition. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Does a long-term relationship kill romantic love?

This article examines the possibility that romantic love (with intensity, engagement, and sexual interest) can exist in long-term relationships. A review of taxonomies, theory, and research suggests that romantic love, without the obsession component typical of early stage romantic love, can and does exist in long-term marriages, and is associated with marital satisfaction, well-being, and high self-esteem. Supporting the separate roles of romantic love and obsession in long-term relationships, an analysis of a moderately large data set of community couples identified independent latent factors for romantic love and obsession and a subsample of individuals reporting very high levels of romantic love (but not obsession) even after controlling for social desirability. Finally, a meta-analysis of 25 relevant studies found that in long- and short-term relationships, romantic love (without obsession) was strongly associated with relationship satisfaction; but obsession was negatively correlated with it in long-term and positively in short-term relationships.

Properties of chemically treated natural amorphous silica fibers as polyurethane reinforcement

A novel kind of short natural fiber obtained from mineral resources, which consists mainly of pure amorphous SiO₂, was chemically modified with aminosilane to improve its interfacial adhesion in polyurethane composites. The effect of the treatment as well as the aspect ratio of the fibers on the mechanical properties of the composite were evaluated and compared with properties obtained with glass fibers composites, which are commonly used in industry. The results obtained show that these natural fibers are potential candidates for the substitution of glass fibers as a reinforcement phase in polymer composites, since the mechanical properties obtained were in all cases equal or superior to the ones obtained with commercial glass fibers.
