“At least one” problem with “some” formal reasoning paradigms

In formal reasoning, the quantifier "some" means "at least one and possibly all." In contrast, reasoners often pragmatically interpret "some" to mean "some, but not all" on both immediate-inference and Euler circle tasks. It is still unclear whether pragmatic interpretations can explain the high rates of errors normally observed on syllogistic reasoning tasks. To address this issue, we presented participants (reasoners) in the present experiments either standard quantifiers or clarified quantifiers designed to precisely articulate the quantifiers' logical interpretations. In Experiment 1, reasoners made significantly more logical responses and significantly fewer pragmatic responses on an immediate-inference task when presented with logically clarified as opposed to standard quantifiers. In Experiment 2, this finding was extended to a variant of the immediate-inference task in which reasoners were asked to deduce what followed from premises they were to assume to be false. In Experiment 3, we used a syllogistic reasoning task and observed that logically clarified premises reduced pragmatic and increased logical responses relative to standard ones, providing strong evidence that pragmatic responses can explain some aspects of the errors made in the syllogistic reasoning task. These findings suggest that standard quantifiers should be replaced with logically clarified quantifiers in teaching and in future research.     

The effect of visual search efficiency on response preparation: neurophysiological evidence for discrete flow

Most models assume that response time (RT) comprises the time required for successive processing stages, but they disagree about whether information is transmitted continuously or discretely between stages. We tested these alternative hypotheses by measuring when movement-related activity began in the frontal eye field (FEF) of macaque monkeys performing visual search. Previous work showed that RT was longer when visual neurons in FEF took longer to select the target, a finding consistent with prolonged perceptual processing during less efficient search. We now report that the buildup of saccadic movement-related activity in FEF is delayed in inefficient visual search. Variability in the delay of movement-related activity accounted for the difference in RT between search conditions and for the variability of RT within conditions. These findings provide neurophysiological support for the hypothesis that information is transmitted discretely between perceptual and response stages of processing during visual search.     

The Benefits of Using Psychotherapy Skills Following Treatment for Depression: An Examination of “Afterwork” and a Test of the Skills Hypothesis in Older Adults

It has long been assumed that one of the reasons clients maintain improvement after psychotherapy is that they learn skills during the course of therapy and continue to apply them once therapy has ended. While research on homework completion and psychotherapy outcome provides support for this assumption, there has been no direct examination of “afterwork,” the use of skills learned in therapy after therapy has ended, or how those posttherapy skills differ across different theoretical approaches. The purpose of this study is to test a skills hypothesis of long-term psychotherapeutic benefit in a sample of 90 older adults who have completed psychotherapy for depression. Helpfulness of the techniques learned in therapy was negatively associated with depressive symptoms up to 2 years after treatment. The number of techniques used was positively correlated with depressive symptoms within 6 months of treatment once helpfulness was controlled, indicating that skills learned in therapy are used when symptoms return. There were also between-group differences in which skills were reported to be covered and used by patients after therapy ended. These findings support the expectation that the benefits of therapy are extended by continuing to use helpful skills learned in therapy.     

Acculturation and Familiarity With, Attitudes Towards and Beliefs about Genetic Testing for Cancer Risk Within Latinas in East Harlem, New York City

Recent research underscores the need for increasing use of genetic testing for cancer risk in Latinos. This study examined the influence of acculturation on attitudes, beliefs about and familiarity with genetic testing for cancer risk in a community-based sample of Latinas in East Harlem, New York City (N = 103). Multivariate linear regression models analyzed the relationship of acculturation to: (1) familiarity (2) perceived benefits (3) perceived barriers and (4) concerns about abuses of genetic testing for cancer risk. Controlling for sociodemographic factors, results revealed that with increasing acculturation Latinas were more familiar with genetic testing (β = 1.62, SE = 0.72, p = 0.03), more likely to cite perceived benefits (β = 1.67, SE = 0.79, p = 0.04), and less likely to report perceived barriers related to genetic testing (β = −2.76, SE = 1.64, p = 0.10). Study results may help inform the development of culturally-appropriate health education outreach materials and programs targeted to increase awareness, knowledge and understanding about genetic testing for cancer risk within Latinas.     

Sleep arrangements and night waking at 6 and 12 months in relation to infants' stress‐induced cortisol responses

The objective of this short‐term longitudinal study was to examine the concurrent and prospective associations of infants' sleep arrangements and night waking with cortisol responses to an inoculation at 6 and 12 months, controlling for several key covariates. To our knowledge, this was the first study to concurrently and prospectively link proximity in sleep arrangements and night waking to physiological stress reactivity. A sample of 92 mother–infant dyads participated in the study when the infants were 6 and 12 months of age, although sample sizes were reduced for some analyses. Both proximal cosleeping arrangements and more frequent night wakings' were associated concurrently with an increased cortisol response to inoculations at both ages. Night waking at 6 months also was associated with a slightly increased cortisol response to inoculation at 12 months. Results aimed at exploring the direction of influence suggested that cosleeping and night waking may influence infant stress physiology rather than the reverse. Adaptive and maladaptive implications of infants' nocturnal experiences and greater stress‐induced cortisol responses are discussed. Copyright © 2009 John Wiley & Sons, Ltd.     

Potential implications of the objectification of women's bodies for women's sexual satisfaction

The present study tested a sociocultural model of women's sexual satisfaction grounded in Objectification Theory (Fredrickson & Roberts, 1997). One hundred and one college women attending university in the UK completed measures of media internalization, body surveillance, body shame, sexual self-esteem, and sexual satisfaction. Consistent with predictions, the results of a path analysis indicated that greater internalization of appearance ideals from media sources leads to more body surveillance, which leads to higher body shame and lower sexual self-esteem, which, in turn, predicts less sexual satisfaction (only reached marginal significance for sexual self-esteem). In addition, body surveillance and body shame directly predicted sexual satisfaction. These results further implicate the sociocultural practices that objectify women in the disruption of women's experiences of sexual satisfaction.     

Health-Related Quality of Life in College Undergraduates with Learning Disabilities: The Mediational Roles of Anxiety and Sadness

Little research has examined health-related quality of life (HRQoL) in adults with learning disabilities in post-secondary settings and the potential relationship between a learning disability and anxiety or sadness. This study examined HRQoL in 68 undergraduate students: 34 students who reported having been diagnosed with a “learning disability” were compared to 34 students who indicated they had not been diagnosed with a learning disability. Participants completed an online survey of anxiety, sadness, and HRQoL, including the SF-36. ANCOVAs on the Emotional Well-Being and Role Limitations Due to Emotional Problems scales from the SF-36 revealed that students reporting a diagnosis of a learning disability were significantly more impaired in Emotional Well-Being. Regression analyses suggested that impairment in Emotional Well-Being was mediated by separate ratings of both anxiety and sadness. Results indicated that those undergraduates reporting learning disabilities suffered from an impaired sense of well-being associated with anxious and sad feelings. A portion of these data were presented at the 2005 annual meetings of the Association for Behavioral and Cognitive Therapies (ABCT).     

RESURGENCE OF INFANT CAREGIVING RESPONSES

Two experiments were conducted to identify the conditions likely to produce resurgence among adult human participants. The preparation was a simulated caregiving context, wherein a recorded infant cry sounded and was terminated contingent upon targeted caregiving responses. Results of Experiment 1 demonstrated resurgence with human participants in this negative reinforcement preparation. Results of Experiment 2 showed that responses with a longer history of reinforcement showed a stronger resurgence effect relative to responses with a shorter and more recent history of reinforcement. These results show that the resurgence phenomenon occurs across populations and types of reinforcers. Additionally, results indicate that length of reinforcement history is a variable that may affect the magnitude of resurgence.     

Effects of guided immune-imagery: The moderating influence of openness to experience

It is widely believed that personality has an important role in determining the effectiveness of guided imagery (GI) interventions. The primary aim of the current study was to examine whether the effect of GI on several outcome measures was dependent upon openness to experience, a theoretically relevant variable previously unexplored as a potential moderator. Thirty-five healthy participants were randomised to an animated imagery, verbal imagery or no-intervention control group, with imagery groups receiving 10 × 20 min sessions. Pre/post-assessments of cortisol, sleep, stress and creativity were administered along with the openness to experience scale. Regression analysis indicated a significant increase in cortisol and decrease in tiredness following verbal GI, but only for those high in openness. The efficacy of GI interventions may be dependent upon openness to experience and this variable should be accounted for in future studies.
