What the precedence effect tells us about room acoustics

Sound produced in a room is typically followed by numerous reflected sounds from nearby surfaces; yet we perceive a single sound source. This perceptual phenomenon, known as the precedence effect, has long been assumed to involve echo suppression, but the nature of this suppression remains unclear. In two experiments, we investigated whether information about the lagging sound's location was perceived. Our hypothesis was that such information is critical because reflected sound can function to inform the listener about objects and structures in the room. Listeners reported hearing more echoes under a stimulus situation that simulated sudden, unexpected changes in the location of the lagging sounds, as compared with stable stimulus conditions. Placement of lagging sounds' locations proved to be critical in that a sudden shift per se did not disrupt the fusion aspect of the precedence effect; the new location had to occupy a site that specified a new reflecting surface. Perception of echoes appears to be modulated by room acoustic information contained in reflected sound and listeners' expectations about this.

"Asking why" from a distance: Its cognitive and emotional consequences for people with major depressive disorder

Although analyzing negative experiences leads to physical and mental health benefits among healthy populations, when people with depression engage in this process on their own they often ruminate and feel worse. Here we examine whether it is possible for adults with depression to analyze their feelings adaptively if they adopt a self-distanced perspective. We examined this issue by randomly assigning depressed and nondepressed adults to analyze their feelings surrounding a depressing life experience from either a self-distanced or a self-immersed perspective and then examined the implications of these manipulations for depressotypic thought accessibility, negative affect, implicit and explicit avoidance, and thought content. Four key results emerged. First, all participants were capable of self-distancing while analyzing their feelings. Second, participants who analyzed their feelings from a self-distanced perspective showed lower levels of depressotypic thought accessibility and negative affect compared to their self-immersed counterparts. Third, analyzing negative feelings from a self-distanced perspective led to an adaptive shift in the way people construed their experience-they recounted the emotionally arousing details of their experience less and reconstrued them in ways that promoted insight and closure. It did not promote avoidance. Finally, self-distancing did not influence negative affect or depressotypic thought accessibility among nondepressed participants. These findings suggest that whether depressed adults' attempts to analyze negative feelings lead to adaptive or maladaptive consequences may depend critically on whether they do so from a self-immersed or a self-distanced perspective.

Sustaining Primary Control Striving for Achievement Goals During Challenging Developmental Transitions: The Role of Secondary Control Strategies

Developmental transitions are imbued with ubiquitous uncertainties that undermine goal striving in many otherwise committed individuals. Our seven-month study examined whether cognitive selective secondary control strategies (motivation-focused thinking) facilitate the enactment of achievement goals among young adults experiencing the landmark school to university transition. Sequential regression analyses demonstrated that (a) achievement goals predicted selective secondary control, (b) selective secondary control predicted behavioral selective primary control striving, and (c) selective primary control predicted final course grades. Findings support Heckhausen et al.'s (2010 Heckhausen , J. , Wrosch , C. , &; Schulz , R. ( 2010 ). A motivational theory of life-span development . Psychological Review , 117 , 32 – 60 .[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) proposition that selective secondary control bolsters selective primary control striving and enables goal attainment during difficult transitions.     

Self-reported personality variability across the social network is associated with interpersonal dysfunction

We describe 2 studies (n=52 and n=82) examining variability in perceptions of personality using a social network methodology. Undergraduate participants completed self-report measures of personality and interpersonal dysfunction and then subsequently reported on their personalities with each of 30 members of their social networks. Results across the 2 studies found substantial variability in participants' perceived personalities within their social networks. Measures of interpersonal dysfunction were associated with the amount of variability in dyadic ratings of personality, specifically Agreeableness and Openness to Experience. Results suggest that personality variability across interpersonal contexts may be an important individual difference related to social behavior and dysfunction.

Self-Perceptions of Comparative Power and Worth in Three Generational Families

This study focused on the extent to which self-perceptions of power and worth differed across members of three-generational families as they compared themselves with other family members. It was hypothesized that self evaluations of worth would show more stability than self evaluations of power in such comparisons. There was support for this hypothesis. Differences regarding self evaluations of power according to gender and generation were also examined. The rank order, from lowest to highest, of perceived comparative power was: female adolescent grandchildren, grandmothers, mothers, male adolescent grandchildren, grandfathers, and fathers. Implications of findings for family therapists are described.
