Do happy faces capture attention? The happiness superiority effect in attentional blink

This study investigated the influence of positive affect on attentional blink (AB) with schematic faces. Results of Experiment 1 showed that the AB effect was smaller for both upright and inverted positive face icons than other face icons (neutral and angry faces) of corresponding orientations, confirming and extending the results of the earlier study by Mack, Pappas, Silverman, and Gay (2002). Results of Experiment 2 demonstrated that this attenuation of AB was unlikely to be attributable to attentional capture by the happy face. Perceptual saliency is suggested as a likely cause of the effect.     

Impact of educational intervention on willingness-to-pay for suicide prevention: a quasi-experimental study among university students in Japan

Many individuals show negative attitudes toward the use of taxes for suicide prevention. Activities that enhance knowledge and awareness of suicide and suicide prevention may increase willingness to pay (WTP) for suicide prevention. WTP is the amount that a consumer will pay for a product or service. The present study examined the influence of educational activities on enhancing knowledge and awareness of suicide and its prevention on WTP. We conducted a quasi-experimental study to examine the influence of lectures on suicide by comparing the amount of change in WTP between two groups over the same period: an intervention group (n = 92) comprising students who participated in the lectures and a control group (n = 128) comprising general university students recruited through an Internet-based survey. A t-test showed that the amount of change was significantly larger in the intervention group (t (152.31) = 2.25, p = .026). Ordinal logistic regression analysis showed that increased WTP was significantly correlated with an annual household income of JPY 4–6 million or higher. It may be appropriate to conclude that participation in lectures about suicide is effective in increasing WTP for suicide prevention.     

Beyond category sorting and pleasantness rating: Inducing relational and item-specific processing

In most studies of relational and item-specific processing, category sorting and pleasantness rating have been the main procedures used to induce these two types of processing. Because the two types of processing have been studied in a wide range of memory phenomena (Hunt & McDaniel, 1993), it is strange that other tasks have not been proposed and tested. The present experiment demonstrates that equivalent results can be obtained with three relational processing tasks (category sorting, narrative construction, and relational imagery) and equivalent results with three itemspecific processing tasks (pleasantness ratings, familiarity ratings, and single imagery).     

Velar movements during speech in two Wernicke aphasic patients

The articulatory gestures of the velum in two Wernicke aphasic patients were examined to compare their performances with those of an apraxic patient by means of the fiberoptic technique. In contrast to the marked variability in the apraxic performance in terms of velum height and segmental duration, the two fluent aphasic subjects showed a relatively high degree of consistency in velar movements throughout several repetitions of nonsense syllables and meaningful words. In addition, both patients exhibited a normal pattern of anticipatory coarticulation. Analyses of the velar movement patterns during the speech-sound error processes of both patients suggested that these errors were not due to an impairment at the level of articulatory programming but to an error in the selection of a target phoneme.     

Multidimensional normative ratings for the International Affective Picture System

The purpose of the present investigation was to replicate and extend the International Affective Picture System norms (Ito, Cacioppo, & Lang, 1998; Lang, Bradley, & Cuthbert, 1999). These norms were developed to provide researchers with photographic slides that varied in emotional evocation, especially arousal and valence. In addition to collecting rating data on the dimensions of arousal and valence, we collected data on the dimensions of consequentiality, meaningfulness, familiarity, distinctiveness, and memorability. Furthermore, we collected ratings on the primary emotions of happiness, surprise, sadness, anger, disgust, and fear. A total of 1,302 participants were tested in small groups. The participants in each group rated a subset of 18 slides on 14 dimensions. Ratings were obtained on 703 slides. The means and standard deviations for all of the ratings are provided. We found our valence ratings to be similar to the previous norms. In contrast, our participants were more likely to rate the slides as less arousing than in the previous norms. The mean ratings on the remaining 12 dimensions were all below the midpoint of the 9-point Likert scale. However, sufficient variability in ratings across the slides indicates that selecting slides on the basis of these variables is feasible. Overall, the present ratings should allow investigators to use these norms for research purposes, especially in research dealing with the interrelationships among emotion and cognition. The means and standard deviations for emotions may be downloaded as an Excel spreadsheet from www.psychonomic.org/archive.     

Classification accuracy across multiple tests following item method directed forgetting

We investigated recall of line-drawing pictures paired at study with an instruction either to remember (TBR items) or to forget (TBF items). Across three 7-minute tests, net recall (items reported independent of accuracy in instructional designation) and correctly classified recall (recall conditional on correct instructional designation) showed directed forgetting. That is, for both measures, recall of TBR items always exceeded recall of TBF items. Net recall for both item types increased across tests at comparable levels showing hypermnesia. However, across tests, correct classification of both item types decreased at comparable levels. Collectively, hypermnesia as measured by net recall is possible for items from multiple sets, but at the cost of accurate source information.     

Counteracting stress through leisure coping: a prospective health study

The purpose of this study was to examine stress-buffer or -counteracting effects of leisure coping, by taking into account several key axes of society (i.e., gender, social class, and age) that are essential to characterize the diverse nature of our society. A 1-year prospective survey of a representative sample (n = 938) from an urban Canadian city was conducted. In the total sample, long-term health protective benefits of leisure coping became evident when stress levels were higher than lower (i.e., support for buffer effects of leisure coping). However, a health-protective effect of leisure coping to counteract the impact of stress on health was found substantially stronger for people with lower social class than for those with higher social class. On the other hand, health-protective stress-buffer effects of leisure coping were evident regardless of people's gender and age. The findings underscore the importance of giving greater attention to the role of leisure as a means of coping with stress in health practices, particularly among marginalized groups such as individuals with lower social class.     

What is the Cause of Confidence Inflation in the Life Events Inventory (LEI) Paradigm?

Briefly imagining, paraphrasing, or explaining an event causes people to increase their confidence that this event occurred during childhood—the imagination inflation effect. The mechanisms responsible for the effect were investigated with a new paradigm. In Experiment 1, event familiarity (defined as processing fluency) was varied by asking participants to rate each event once, three times, or five times. No inflation was found, indicating that familiarity does not account for the effect. In Experiment 2, richness of memory representation was manipulated by asking participants to generate zero, three, or six details. Confidence increased from the initial to the final rating in the three- and six-detail conditions, indicating that the effect is based on reality-monitoring errors. However, greater inflation in the three-detail condition than in the six-detail condition indicated that there is a boundary condition. These results were also consistent with an alternative hypothesis, the mental workload hypothesis.
