Active (not passive) spatial imagery primes temporal judgements

Previous research has shown that primes that induce particular spatial perspectives can influence temporal judgements. However, most studies have used priming stimuli that involve both spatial and motor language and imagery. Here we ask whether the motor content of these stimuli plays an important role in their ability to serve as effective primes. A total of 198 adult participants made temporal judgements after exposure to spatial primes involving varying levels of imagined effort. Spatial primes involving imagined motor actions, but not those involving equivalent passive motions through space, successfully primed decisions about time. This suggests that motor content, rather than spatial content alone, contributes to the priming effects that arise when people make temporal judgements after exposure to particular spatial perspectives.     

Aging and the discrimination of 3-D shape from motion and binocular disparity

Two experiments evaluated the ability of younger and older adults to visually discriminate 3-D shape as a function of surface coherence. The coherence was manipulated by embedding the 3-D surfaces in volumetric noise (e.g., for a 55?% coherent surface, 55?% of the stimulus points fell on a 3-D surface, while 45?% of the points occupied random locations within the same volume of space). The 3-D surfaces were defined by static binocular disparity, dynamic binocular disparity, and motion. The results of both experiments demonstrated significant effects of age: Older adults required more coherence (tolerated volumetric noise less) for reliable shape discrimination than did younger adults. Motion-defined and static-binocular-disparity-defined surfaces resulted in similar coherence thresholds. However, performance for dynamic-binocular-disparity-defined surfaces was superior (i.e., the observers?? surface coherence thresholds were lowest for these stimuli). The results of both experiments showed that younger and older adults possess considerable tolerance to the disrupting effects of volumetric noise; the observers could reliably discriminate 3-D surface shape even when 45?% of the stimulus points (or more) constituted noise.     

Action-specific effects underwater

Action-specific effects on perception are apparent in terrestrial environments. For example, targets that require more effort to walk, jump, or throw to look farther away than when the targets require less effort. Here, we examined whether action-specific effects would generalize to an underwater environment. Instead, perception might be geometrically precise, rather than action-specific, in an environment that is novel from an evolutionary perspective. We manipulated ease to swim by giving participants swimming flippers or taking them away. Those who estimated distance while wearing the flippers judged underwater targets to be closer than did participants who had taken them off. In addition, participants with better swimming ability judged the targets to be closer than did those with worse swimming ability. These results suggest perceived distance underwater is a function of the perceiver's ability to swim to the targets.     

Rules of engagement: incomplete and complete pronoun resolution

Research on shallow processing suggests that readers sometimes encode only a superficial representation of a text and fail to make use of all available information. Greene, McKoon, and Ratcliff (1992) extended this work to pronouns, finding evidence that readers sometimes fail to automatically identify referents even when these are unambiguous. In this paper we revisit those findings. In 11 recognition probe, priming, and self-report experiments, we manipulated Greene et al.'s stories to discover under what circumstances a pronoun's referent is automatically understood. We lengthened the stories from 4 to 8 lines. This simple manipulation led to automatic and correct resolution, which we attribute to readers' increased engagement with the stories. We found evidence of resolution even when the additional text did not mention the pronoun's referent. In addition, our results suggest that the pronoun temporarily boosts the referent's accessibility, an advantage that disappears by the end of the next sentence. Finally, we present evidence from memory experiments that supports complete pronoun resolution for the longer but not the shorter stories.     

A qualitative analysis of attitudes to face transplants: contrasting views of the general public and medical professionals

While there has been a considerable criticism and debate about face transplantation from ethicists, surgeons and psychologists, little is known about the attitudes of medical professionals and the general public whose support will be necessary if face transplants are to be accepted. This study therefore conducted in-depth, semi-structured interviews with medical professionals (8) and the general public (8) to explore their understanding of and attitudes to face transplants. A thematic analysis was used to analyse these data. Five overarching themes were identified including agreement in principal, caveats and conditions, medical and technical difficulties, function and appearance, and the significance of the human face. The analysis revealed overwhelming support in principle for face transplants, but with important caveats and conditions. Both groups shared clear representations of deserving and undeserving candidates, and concerns about psychological adjustment. The general public sample demonstrated little understanding of medical implications or the consequences of a failed graft, which did concern the medical professionals. Neither group showed a clear understanding of the psychological or social factors required to predict best outcomes and identify suitable candidates. Analyses revealed a stereotypical belief from both groups that the life of a severely disfigured recipient is intolerable without this operation.     

Work–family interpersonal capitalization: Sharing positive work events at home

In a 3-week experience-sampling study of 52 full-time employees, the authors investigated the within-individual relationships among positive work events, affective states, and job satisfaction. They also examined the influence of work–family interpersonal capitalization (sharing work events with one’s spouse or partner at home) on employees’ job and relationship satisfaction. Results revealed that positive events influenced job satisfaction through positive affect, and work–family interpersonal capitalization on the most positive work event of the day positively impacted job satisfaction over and above the effects of the event’s pleasantness and of the number of other positive work events experienced that day.     

Social influence modulates the neural computation of value

Social influence--individuals' tendency to conform to the beliefs and attitudes of others--has interested psychologists for decades. However, it has traditionally been difficult to distinguish true modification of attitudes from mere public compliance with social norms; this study addressed this challenge using functional neuroimaging. Participants rated the attractiveness of faces and subsequently learned how their peers ostensibly rated each face. Participants were then scanned using functional MRI while they rated each face a second time. The second ratings were influenced by social norms: Participants changed their ratings to conform to those of their peers. This social influence was accompanied by modulated engagement of two brain regions associated with coding subjective value--the nucleus accumbens and orbitofrontal cortex--a finding suggesting that exposure to social norms affected participants' neural representations of value assigned to stimuli. These findings document the utility of neuroimaging to demonstrate the private acceptance of social norms.     

Increasing On-Task Behavior Using Teacher Attention Delivered on a Fixed-Time Schedule

The effectiveness of fixed-time delivery of attention to increase the on-task behavior of 2 students in general education was examined. The teacher in this study provided attention to students on a 5-min fixed-time schedule and responded to students in her typical manner between cued intervals. An ABAB withdrawal design was used to test the effects of the intervention. The results of this study indicate that a fixed-time schedule of attention was effective in increasing students’ on-task behavior and decreasing their off-task behavior. Implications of the study for research and practice are discussed.     

Genetic Testing Likelihood: The Impact of Abortion Views and Quality of Life Information on Women’s Decisions

Little is known about factors predicting the likelihood of choosing genetic testing in college aged women versus older women, including knowledge of quality of life (QOL) associated with a disorder. Using vignettes with female college students (Experiment 1: n = 257, mean age = 19.70 yrs) and female faculty/staff/alumni (Experiment 2: n _nulliparous = 83, mean age = 30.20 yrs; n _mothers = 53, mean age = 33.77 yrs), we examined the contribution of multiple factors to predicting genetic testing likelihood for cystic fibrosis. We investigated malleable situational factors (style of genetic risk presentation and providing QOL information including physical and social aspects) and stable dispositional factors (abortion views). Parity (i.e., prior births) was more influential in women’s genetic testing likelihood than was age. Greater acceptability of abortion for oneself and self-assessed knowledge following QOL information were predictors of higher testing likelihood for college students. Greater acceptability of abortion for another person was a predictor for nulliparous women. Abortion views moderated the effect of predictors for nulliparous women and mothers. Findings encourage genetic counselors to utilize QOL information to promote informed decision making through genetic testing.     

Is risky sexual behavior continuous or categorical? A taxometric analysis of the Sexual Risk Survey

Risky sexual behaviors are behaviors that involve the possibility of an adverse outcome, such as contracting a sexually transmitted infection or unwanted pregnancy. The question of whether risky sexual behavior exists as a discrete class (i.e., taxon) or as a dimensional construct has not previously been explored. The authors performed a set of taxometric analyses on 4 factor scales derived from the Sexual Risk Survey (Turchik & Garske, 2009) with data from 1,103 college students. The results provided consistent support for a dimensional latent structure in which variations in reported risky sexual behavior reflect differences in degree and not differences in kind. The implications of these findings for the assessment of risky sexual behavior are discussed.
