Why so confident? The influence of outcome desirability on selective exposure and likelihood judgment

Previous studies that have directly manipulated outcome desirability have often found little effect on likelihood judgments (i.e., no desirability bias or wishful thinking). The present studies tested whether selections of new information about outcomes would be impacted by outcome desirability, thereby biasing likelihood judgments. In Study 1, participants made predictions about novel outcomes and then selected additional information to read from a buffet. They favored information supporting their prediction, and this fueled an increase in confidence. Studies 2 and 3 directly manipulated outcome desirability through monetary means. If a target outcome (randomly preselected) was made especially desirable, then participants tended to select information that supported the outcome. If made undesirable, less supporting information was selected. Selection bias was again linked to subsequent likelihood judgments. These results constitute novel evidence for the role of selective exposure in cases of overconfidence and desirability bias in likelihood judgments.     

Effects of Action Video Game Experience on Change Detection

Reflected sounds are often treated as an acoustic problem because they produce false localization cues and decrease speech intelligibility. However, their properties are shaped by the acoustic properties of the environment and therefore are a potential source of information about that environment. The objective of this study was to determine whether information carried by reflected sounds can be used by listeners to enhance their awareness of their auditory environment. Twelve listeners participated in two auditory training tasks in which they learned to identify three environments based on a limited subset of sounds and then were tested to determine whether they could transfer that learning to new, unfamiliar sounds. Results showed that significant learning occurred despite the task difficulty. An analysis of stimulus attributes suggests that it is easiest to learn to identify reflected sound when it occurs in sounds with longer decay times and broadly distributed dominant spectral components.     

Health and well-being

Eudaimonistic theorists of welfare have recently attacked conative accounts of welfare. Such accounts, it is claimed, are unable to classify states normally associated with physical and emotional health as non-instrumentally good and states associated with physical and psychological damage as non-instrumentally bad. However, leading eudaimonistic theories such as the self-fulfillment theory and developmentalism have problems of their own. Furthermore, conative theorists can respond to this challenge by dispositionalizing their theories, i.e., by saying that it is not merely the realization of one’s values that is non-instrumentally good for one, but that the disposition to realize one’s values is also non-instrumentally good for one. This approach, properly elaborated, can accommodate the idea that, in many cases, states normally associated with physical and psychological health (or unhealth) are non-instrumentally good (or bad). It also preserves the many well-known advantages of conative theories.     

Friendship and epistemic norms

Simon Keller and Sarah Stroud have both argued that the demands of being a good friend can conflict with the demands of standard epistemic norms. Intuitively, good friends will tend to seek favorable interpretations of their friends’ behaviors, interpretations that they would not apply to strangers; as such they seem prone to form unjustified beliefs. I argue that there is no such clash of norms. In particular, I argue that friendship does not require us to form beliefs about our friends in the biased fashion suggested by Stroud and Keller. I further argue that while some slight bias in belief-formation might be permitted by friendship, any such bias would fall within the bounds of epistemic propriety.     

Intuitively detecting what is hidden within a visual mask: Familiar–novel discrimination and threat detection for unidentified stimuli

Recognition without identification is the finding that, among recognition test items that go unidentified (as when a word is unidentified from a fragment), participants can discriminate those that were studied from those that were unstudied. In the present study, we extended this phenomenon to the more life-like situation of discriminating known from novel stimuli. Pictures of famous and nonfamous faces (Exp. 1), famous and nonfamous scenes (Exp. 2), and threatening and nonthreatening images (Exp. 3) were filtered in order to impede identification. As in list-learning recognition-without-identification paradigms, participants attempted to identify each image (e.g., whose face it was, what scene it was, or what was in the picture) and rated how familiar the image seemed on a scale of 0 (very unfamiliar) to 10 (very familiar). Among the unidentified stimuli, higher familiarity ratings were given to famous than to nonfamous faces (Exp. 1) and scenes (Exp. 2), and to threatening than to nonthreatening living/animate (but not to nonliving/nonanimate) images (Exp. 3). These findings suggest that even when a stimulus is too occluded to allow for conscious identification, enough information can be processed to allow a sense of familiarity or novelty with it, which appears also to be related to the sense of whether or not a living creature is a threat. That the sense of familiarity for unidentified stimuli may be related to threat detection for living or animate things suggests that it may be an adaptive aspect of human memory.     

Factors of Empowerment for Women in Recovery from Substance Use

Empowerment is an interdisciplinary construct heavily grounded in the theories of community psychology. Although empowerment has a strong theoretical foundation, few context-specific quantitative measures have been designed to evaluate empowerment for specific populations. The present study explored the factor structure of a modified empowerment scale with a cross-sectional sample of 296 women in recovery from substance use who lived in recovery homes located throughout the United States. Results from an exploratory factor analysis identified three factors of psychological empowerment which were closely related to previous conceptualizations of psychological empowerment: self-perception, resource knowledge and participation. Further analyses demonstrated a hierarchical relationship among the three factors, with resource knowledge predicting participation when controlling for self-perception. Finally, a correlational analysis demonstrated the initial construct validity of each factor, as each factor of empowerment was significantly and positively related to self-esteem. Implications for the application of psychological empowerment theory and research are discussed.     

Effects of rhyme and spelling patterns on auditory word ERPs depend on selective attention to phonology

ERP responses to spoken words are sensitive to both rhyming effects and effects of associated spelling patterns. Are such effects automatically elicited by spoken words or dependent on selectively attending to phonology? To address this question, ERP responses to spoken word pairs were investigated under two equally demanding listening tasks that directed selective attention either to sub-syllabic phonology (i.e., rhyme judgments) or to melodies embedded within the words. ERPs elicited when participants selectively attended to phonology demonstrated a rhyming effect that was concurrent with online stimulus encoding and an orthographic effect that emerged later. ERP responses to the same stimuli presented under melodic focus, however, showed no evidence of sensitivity to rhyme or spelling patterns. Results reveal limitations to the automaticity of such ERP effects, suggesting that rhyme effects may depend, at least to some degree, on allocation of attention to phonology, which may in turn activate task-incidental orthographic information.     

Language aptitude for pronunciation in advanced second language (L2) Learners: Behavioural predictors and neural substrates

Individual differences in second language (L2) aptitude have been assumed to depend upon a variety of cognitive and personality factors. Especially, the cognitive factor phonological working memory has been conceptualised as language learning device. However, strong associations between phonological working memory and L2 aptitude have been previously found in early-stage learners only, not in advanced learners. The current study aimed at investigating the behavioural and neurobiological predictors of advanced L2 learning. Our behavioural results showed that phonetic coding ability and empathy, but not phonological working memory, predict L2 pronunciation aptitude in advanced learners. Second, functional neuroimaging revealed this behavioural trait to be correlated with hemodynamic responses of the cerebral network of speech motor control and auditory-perceptual areas. We suggest that the acquisition of L2 pronunciation aptitude is a dynamic process, requiring a variety of neural resources at different processing stages over time.     

Non-g residuals of the SAT and ACT predict specific abilities

This research examined whether non-g residuals of the SAT and ACT subtests, obtained after removing g, predicted specific abilities. Non-g residuals of the verbal and math subtests of the SAT and ACT were correlated with academic (verbal and math) and non-academic abilities (speed and shop), both based on the Armed Services Vocational Aptitude Battery. Non-g residuals of the SAT and ACT math subtests were positively related to math ability and negatively to verbal ability, whereas the opposite pattern was found for the verbal subtests. Non-g residuals of both sets of subtests were weakly related to non-academic abilities. The results support an investment theory of skills and abilities: Investing in skills in one area (e.g., math) improves abilities in that area but lowers abilities in competing areas (e.g., verbal).     

Self-Stigma in Substance Abuse: Development of a New Measure

Little attention has been paid to the examination and measurement of self-stigma in substance misuse. This paper aims to fill this gap by reporting on the development of a new scale to measure self-stigma experienced by people who are misusing substances, the Substance Abuse Self-Stigma Scale. Content validity and item refinement occurred through an iterative process involving a literature search, focus groups, and expert judges. Psychometric properties were examined in a cross-sectional study of individuals (n?=?352) receiving treatment for substance misuse. Factor analyses resulted in a 40-item measure with self devaluation, fear of enacted stigma, stigma avoidance, and values disengagement subscales. The measure showed a strong factor structure and good reliability and validity overall, though the values disengagement subscale showed a mixed pattern. Results are discussed in terms of their implications for studies of stigma impact and intervention.
