Binocular depth from surfaces versus volumes

Subjects were asked to compare the relative depths of two binocular targets embedded in different random dot stereogram backgrounds. The disparities of the background points were either randomized, corresponding to a scattering of points within a volume, or arranged according to a sawtooth (triangle-wave) disparity profile (i.e., a set of slanted planar surfaces separated by sharp depth discontinuities). When the targets were embedded in the random volume, their depths were perceived in accordance with their relative disparities. But when the target points were embedded in the sawtooth surfaces their depths were systematically misperceived in a manner predicted by the incorrect depth interpretation of the background points. Rather than seeing a sawtooth pattern, the background points resembled a staircase in depth, and the targets, which appeared embedded in different steps, were misjudged in depth accordingly. The effect suggests a distinction between the depth processing of isolated binocular features and those associated with continuous surfaces.     

The Process of Family Reconstruction after DNA Testing for Huntington Disease

The needs of families to reconstruct their relationships in response to the DNA testing for Huntington disease of one or more of their asymptomatic members are presented. Data were collected from family interviews with 18 families, and from their responses on a post interview questionnaire. Findings are that families need to (a) address unfinished business associated with the decision for testing; (b) bring family members, peripheral in the decision for testing, into the loop; (c) reorganize patterns of communication and roles altered by the testing and heal ruptures in family membership; and (d) revise family stories about illness to provide a meaning for HD and explain the test results in a way that leaves them with a sense of mastery. Findings suggest that families should be more involved in the initial decision for testing of a member and that protocols should be established to provide help for their ongoing adjustment.     

So Close and Yet So Far: Construal Level Moderates Cultivation Effects

The cultivation effect is well established: The more media we consume, the more our worldviews come to reflect the mediated world. Several advancements have been made in the past decade exploring the processes underlying the effect. Importantly, the judgments are often heuristically based (Shrum, 2001 Shrum, L. J. (2001). Processing strategy moderates the cultivation effect. Human Communication Research, 27, 94–120.[Crossref], [Web of Science ®] , [Google Scholar], 2009 Shrum, L. J. (2009). Media consumption and perceptions of social reality: Effects and underlying processes. In J. Bryant &; M. B. Oliver (Eds.), Media effects: Advances in theory and research (pp. 50–73). New York, NY: Routledge. [Google Scholar]), with relevance of the media information an important moderator of this process. Mental construal level, in which people are considered to be thinking on a relatively concrete (psychologically close, specific) level or a relatively abstract (psychologically distant, general) level, may influence these cognitive processes. The present studies find that mental construal level (concrete or abstract) moderates the classic cultivation effect for first-order judgments. Specifically, concrete construal encourages the cultivation effect with a stronger relationship between media consumption and violence prevalence estimates, but abstract construal reduces the effect. Comparison to a control condition in Experiment 2 indicates that concrete construal may be the default state for cultivation effects. One possible explanation for the effect of construal on cultivation effects is that construal influences relevance of and reliance on media cues in judgment formation.     

Gender and family factors as predictors of late adolescent emotional expressiveness and adjustment: A longitudinal study

This study examined the longterm effects of the socialization of emotion in a sample of European American families. Late adolescents, whose families had been more emotionally expressive and accepting of emotions when they were in fifth grade, were more likely to report showing emotions not traditionally associated with their gender roles—specifically, males reported a greater propensity for crying, and females reported a greater tendency to express anger. In addition, in late adolescence, greater frequency of showing fear and showing warmth or affection were associated with higher levels of social and psychological adjustment—whereas crying was associated with better adjustment for males and poorer adjustment for females. Overall, adolescent females tended to report a higher level of emotional expressiveness and a higher level of family support of emotions than did adolescent males.     

Guided Recovery: An Interpretative Phenomenological Analysis of Service Users’ Experiences of Guided Self-Help for Bulimic and Binge Eating Disorders

The efficacy of Cognitive Behavioral Therapy–based Guided Self-Help for mild to moderate bulimia and binge eating disorders has been well supported. However, limited research has explored in-depth individual experiences of this treatment approach. In-depth semi-structured interviews were conducted with 4 individuals who had completed Cognitive Behavioral Therapy–based Guided Self-Help (CBT-GSH) for bulimic or binge eating disorders. The interviews were transcribed verbatim and subsequently analyzed using Interpretative Phenomenological Analysis (IPA). Three superordinate themes emerged: Autonomy and volition; A dynamic relationship: the guided and the guide; and The unwanted friend. The reciprocal nature of the guide/guided relationship was identified as integral to the success of the therapeutic approach. However, participants expressed initial uncertainty towards the therapeutic process, and experienced an uncomfortable dissonance between a lack of volition in therapy seeking and the need to continually self-prescribe CBT-GSH. The findings affirm the central role of the guide in promoting motivation to engage with therapy and highlight the potential benefits of in-session weighing. However, it may be necessary to provide additional support on commencing CBT-GSH to address concerns about the therapeutic approach in this group.     

Potentiation and blocking of conditioned flavour and context aversions

Experiments 1, 2, and 3 demonstrated that the place in which rats had been made sick subsequently blocked the development of an aversion to a novel flavour that was presented in that place and paired with illness. These experiments also showed that a poisoned flavour subsequently potentiated the acquisition of an aversion to a novel place in which it was presented and paired with illness. Experiments 4 and 5 examined the hypothesis that the potentiation effect was mediated by the association between the place and the averted flavour rather than by the association between the place and the illness. However, there was no evidence that the place acquired aversive control over ingestive behaviours simply as a consequence of it having contained the averted flavour. Further, reinforcement of the aversive flavour outside the place-flavour compound increased flavour aversions but decreased, rather than increased, place aversions. These failures to detect evidence for an association between the place and the poisoned flavour led to a consideration of whether the animals were sensitive to the relation between the place and the poisoned flavour. Experiment 6 demonstrated that the potentiation effect was in fact contingent upon the relation between the place and the poisoned flavour, as was required by the view that the poisoned flavour had facilitated the association between the place and the illness.     

The Theory of Reasoned Action and the Role of External Factors on Heterosexual Men's Monogamy and Condom Use1

Although the majority of prevention efforts have focused on women, reduction of heterosexual transmission of STDs also requires interventions for men, necessitating understanding of men's safer sex decision making. In a random sample of 486 heterosexually active men, the theory of reasoned action (TRA) was used to predict intentions to use condoms with casual partners, as well as 2 steady‐partner safer sex behaviors: mutual monogamy and condom use. The basic TRA model fit the data well. Expanded models identified the mediated (via attitudes, social norms, and self‐efficacy) and, for some, direct effects on intentions and behavior of selected intrapersonal, interpersonal, and sociocultural variables. Results suggest that the role of external variables might vary depending on the behaviors in question.
