Why are auditory novels distracting? Contrasting the roles of novelty, violation of expectation and stimulus change

Past studies show that novel auditory stimuli, presented in the context of an otherwise repeated sound, capture participants’ attention away from a focal task, resulting in measurable behavioral distraction. Novel sounds are traditionally defined as rare and unexpected but past studies have not sought to disentangle these concepts directly. Using a cross-modal oddball task, we contrasted these aspects orthogonally by manipulating the base rate and conditional probabilities of sound events. We report for the first time that behavioral distraction does not result from a sound’s novelty per se but from the violation of the cognitive system’s expectation based on the learning of conditional probabilities and, to some extent, the occurrence of a perceptual change from one sound to another.     

Future-oriented emotions in the prediction of binge-drinking intention and expectation: the role of anticipated and anticipatory emotions

The Theory of Planned Behavior (TPB) offers a parsimonious explanation of purposive behavior, but in the study of healthy and risk behaviors its sufficiency may be questioned. Working with binge-drinking, a very common risk behavior in Spanish undergraduate students, we used two strategies for improving predictions from TPB: using behavioral intention (BI) and behavioral expectation (BE) as proximal antecedents of behaviors and adding as new predictors two future-oriented emotions (anticipated and anticipatory). Hierarchical regression analyses show that while anticipated emotions improved TPB explanations of BI, anticipatory emotions improved the explanations of BE. The present results show the influence of future emotions in the prediction of behavioral intention and behavioral expectation.     

Affective norms for 380 Spanish words belonging to three different semantic categories

Emotional words are increasingly used in the study of word processing. To elucidate whether the experimental effects obtained with these words are due either to their affective content or to other semantic characteristics, it is necessary to conduct experiments with affectively valenced words obtained from different semantic categories. In the present article, we present affective ratings for 380 Spanish words belonging to three semantic categories: animals, people, and objects. The norms are based on the assessments made by 504 participants, who rated about 47 words either in valence and arousal, by using the Self-Assessment Manikin (Bradley & Lang, Journal of Behavioral Therapy and Experimental Psychiatry, 25, 49-59. 1994), or in concreteness and familiarity. These ratings will help researchers select stimuli for experiments in which both the affective properties of words and their membership to a given semantic category have to be taken into account. The database is available as an online supplement for this article.     

Effects of level of processing on memory for affectively valenced words

In this study we tested whether subjects remember affectively valenced stimuli better than neutral stimuli when their attention is not focused on the affective charge of the stimuli during encoding. We tested memory for positive, negative, and neutral words in three memory tasks and using two encoding conditions (physical and semantic). Our results show that subjects remember affectively valenced stimuli better than neutral stimuli when they encode them according to their emotional content as well as to other features of the stimuli. However, although both positive and negative words are better remembered than neutral ones when semantically encoded, only positive words are better remembered than neutral ones when physically encoded. These results suggest that the affective charge of a stimulus (especially when positive) can affect retention even when a subject's attention has not focused on it during encoding.     

Spontaneous facial expressions of happy bowlers and soccer fans

Kraut and Johnston (1979) found surprisingly few smiles in large samples of bowlers and hockey fans during happy events--unless they were simultaneously engaged in social interaction. A limitation of their studies is that there was no direct test of subjects' actual emotional experience at the moments in which they were observed. This article reports two field studies in which emotions were reported by bowlers and by soccer fans. Analysing facial behaviour of those who reported happiness, we found a low probability of smiling in the absence of social interaction (.09 for bowlers and .07 for soccer fans) and a high probability of smiling during social interaction (.78 and .70). These findings question the common assumption that smiles are an indicator of happiness per se, and support the alternative hypothesis of a more complex and indirect relationship between smiling and happiness.     

Brief report Effects of spinal cord injuries on the subjective component of emotions

Responses to a structured interview by 19 patients with spinal cord injuries (SCI) (7 women and 12 men) concerning their past (pre‐injury) and present emotions were analysed and compared with responses by 19 SCI‐free controls matched for sex, age, and education. In addition, subjects assessed the valence and arousal of 10 pleasant, 10 neutral, and 10 unpleasant pictures selected from the International Affective Picture System. The results indicate that there is no decrease in emotional experience among individuals with SCI compared with those without. For all the emotional scales (joy, love, sentimentalism, positive emotions as a whole, fear, anger, sadness, and negative emotions as a whole) the SCI group always showed either no change or an increase; this increase was significantly higher in SCI than in control subjects for sadness. No differences were observed between the two groups in the subjective assessment of the pictures. The implications of the results for the James versus Cannon controversy on the theory of emotions are discussed.     

Application of family therapy theory to complex social issues: using the WebQuest in family therapy training

This paper describes how the WebQuest is used to foster critical thinking and application of theory to complex social problems in a Master's level class on contemporary family therapy theories. The issue of child trafficking and prostitution is explored through the web‐based inquiry learning where scaffold learning is provided. Scaffolding includes resource links and guidance on cognitive and social skills, which are provided to facilitate the learner's development. The WebQuest design includes the task, the process and the evaluation rubrics. Student feedback on the WebQuest was positive and included increased motivation in learning, critical thinking and global awareness.
