Object-based auditory facilitation of visual search for pictures and words with frequent and rare targets

Auditory and visual processes demonstrably enhance each other based on spatial and temporal coincidence. Our recent results on visual search have shown that auditory signals also enhance visual salience of specific objects based on multimodal experience. For example, we tend to see an object (e.g., a cat) and simultaneously hear its characteristic sound (e.g., “meow”), to name an object when we see it, and to vocalize a word when we read it, but we do not tend to see a word (e.g., cat) and simultaneously hear the characteristic sound (e.g., “meow”) of the named object. If auditory–visual enhancements occur based on this pattern of experiential associations, playing a characteristic sound (e.g., “meow”) should facilitate visual search for the corresponding object (e.g., an image of a cat), hearing a name should facilitate visual search for both the corresponding object and corresponding word, but playing a characteristic sound should not facilitate visual search for the name of the corresponding object. Our present and prior results together confirmed these experiential association predictions. We also recently showed that the underlying object-based auditory–visual interactions occur rapidly (within 220 ms) and guide initial saccades towards target objects. If object-based auditory–visual enhancements are automatic and persistent, an interesting application would be to use characteristic sounds to facilitate visual search when targets are rare, such as during baggage screening. Our participants searched for a gun among other objects when a gun was presented on only 10% of the trials. The search time was speeded when a gun sound was played on every trial (primarily on gun-absent trials); importantly, playing gun sounds facilitated both gun-present and gun-absent responses, suggesting that object-based auditory–visual enhancements persistently increase the detectability of guns rather than simply biasing gun-present responses. Thus, object-based auditory–visual interactions that derive from experiential associations rapidly and persistently increase visual salience of corresponding objects.     

Personality in DSM-5: helping delineate personality disorder content and framing the metastructure

The transition from the Diagnostic and Statistical Model of Mental Disorders (4th ed., text revision [DSM-IV-TR]; American Psychiatric Association, 2000 ) to the fifth edition (DSM-5) represents an unprecedented opportunity to integrate dimensional personality trait models into the official nosology. Not surprisingly, a variety of issues have arisen in contemplating this challenging integration. In this article, we address how a dimensional personality trait model could be a helpful component of DSM-5, from the perspective of our roles as work group members and advisors involved in the creation of a trait model and corresponding assessment instrument. We focus in particular on two potential roles for a trait model in DSM-5 that are under official consideration. First, a dimensional personality trait model might be helpful in delineating the content of personality disorders. Second, a trait model might assist in organizing the "metastructure" of DSM-5 (i.e., the arrangement of chapters and other broader classificatory rubrics).     

Is the enhancement of memory due to reward driven by value or salience?

Past research using two levels of reward has shown that the higher-value items are remembered better than lower-value items and this enhancement is assumed to be driven by an effect of reward value. In the present study, multiple levels of reward were used to test the influence of reward salience on memory. Using a value-learning procedure, words were associated with reward values, and then memory for these words was later tested with free recall. Critically, multiple reward levels were used, allowing us to test two specific hypotheses whereby rewards can influence memory: (a) higher value items are remembered better than lower value items (reward value hypothesis), and (b) highest and lowest value items are remembered best and intermediate-value items are remembered worst (following a U-shaped relationship between value and memory; reward salience hypothesis). In two experiments we observed a U-shaped relationship between reward value and memory, supporting the notion that memory is enhanced due to reward salience, and not purely through reward value.     

Between Integrity and Despair: Toward Construct Validation of Erikson’s Eighth Stage

A new measure of Erikson’s final psychosocial stage, Integrity versus Despair, is presented and validated across two studies. In the first, 97 adults (68 women and 31 men) aged 65 and older responded to this measure: the Self-Examination Interview (SEI). Responses on the SEI were treated both categorically and dimensionally (continuous scores) with respect to four integrity statuses: Integrated, Nonexploring, Pseudointegrated, and Despairing. In Study One, categorical and dimensional Integrity statuses were examined in relation to five convergent measures: the Integrity subscale of the Modified Eriksonian Psychosocial Inventory, Openness to Experience, the Competence subscale of the California Personality Inventory, the Geriatric Depression Scale, and Perceived Health. As hypothesized, Integrated respondents were socially competent and resilient; Nonexploring persons conventional; Pseudointegrated respondents immature; and Despairing persons, demoralized. A subsample of participants took a semi-structured Adult Identity Status Interview. Integrated persons were most often Identity Achieved; Pseudointegrated and Nonexploring persons were most often Foreclosed. Study Two evaluated a new sample of 70 persons (51 women and 19 men) aged 70 and older. It generally confirmed the Integrity statuses developed in Study One, extending them to variables related to complexity and maturity of sociomoral reasoning and thinking style. As expected, the Integrated status was negatively related, and the Nonexploring status positively related, to intolerance for ambiguity. The highest levels of sociomoral reasoning occurred most in the Integrated status group, as did dialectical reasoning. In contrast, the Nonexploring and Despairing statuses had more formistic-mechanistic reasoners. Pseudointegrated persons produced the highest number of invalid protocols. The importance of present findings and implications of these studies for future directions in integrity research are discussed.     

WHAT PREDICTS THE OWN-AGE BIAS IN FACE RECOGNITION MEMORY?

Younger and older adults' visual scan patterns were examined as they passively viewed younger and older neutral faces. Both participant age groups tended to look longer at their own-age as compared to other-age faces. In addition, both age groups reported more exposure to own-age than other-age individuals. Importantly, the own-age bias in visual inspection of faces and the own-age bias in self-reported amount of exposure to young and older individuals in everyday life, but not explicit age stereotypes and implicit age associations, significantly and independently predicted the own-age bias in later old/new face recognition. We suggest these findings reflect increased personal and social relevance of, and more accessible and elaborated schemas for, own-age than other-age faces.
