Breast Cancer in Men: A Need for Psychological Intervention

Male breast cancer is a serious issue that needs to be addressed more fully by the medical and public community. However, due to a lack of awareness and limited research on the topic, there is a general absence of knowledge concerning the psychological implications of this disease in men as well as a need for greater understanding of the medical diagnosis and treatment of male breast carcinoma. Similarly, there still remains a considerable gender difference between the awareness of female breast cancer and male breast cancer Although breast cancer in men makes up only 1% of all breast cancers reported in the United States, it is increasing in incidence. There are approximately 2000 new cases and approximately 450 deaths due to male breast cancer each year. Breast cancer diagnosis and treatment in men is very similar to that described in women, however, it has been shown that men are being diagnosed at a later stage of the disease than women.     

Toward a complete decision model of item and source recognition

In a recognition memory test, subjects may be asked to decide whether a test item is old or new (item recognition) or to decide among alternative sources from which it might have been drawn for study (source recognition). Confidence-rating-based receiver operating characteristic (ROC) curves for these superficially similar tasks are quite different, leading to the inference of correspondingly different decision processes. A complete account of source and item recognition will require a single model that can be fit to the entire data set. We postulated a detection-theoretic decision space whose dimensions, in the style of Banks (2000), are item strength and the relative strengths of the two sources. A model that assumes decision boundaries of constant likelihood ratios, source guessing for unrecognized items, and nonoptimal allocation of attention can account for data from three canonical data sets without assuming any processes specifically devoted to recollection. Observed and predicted ROCs for one of these data sets are given in the article, and ROCs for the other two may be downloaded from the Psychonomic Society’s Archive of Norms, Stimuli, and Data, www.psychonomic.org/archive.     

ASSESSING OBSERVER ACCURACY IN CONTINUOUS RECORDING OF RATE AND DURATION: THREE ALGORITHMS COMPARED

The three algorithms most frequently selected by behavior‐analytic researchers to compute interobserver agreement with continuous recording were used to assess the accuracy of data recorded from video samples on handheld computers by 12 observers. Rate and duration of responding were recorded for three samples each. Data files were compared with criterion records to determine observer accuracy. Block‐by‐block and exact agreement algorithms were susceptible to inflated agreement and accuracy estimates at lower rates and durations. The exact agreement method appeared to be overly stringent for recording responding at higher rates (23.5 responses per minute) and for higher relative duration (72% of session). Time‐window analysis appeared to inflate accuracy assessment at relatively high but not at low response rate and duration (4.8 responses per minute and 8% of session, respectively).     

Naming and Nonexistence

I defend a cluster of views about names from fiction and myth. The views are based on two claims: first, proper names refer directly to their bearers; and second, names from fiction and myth are genuinely empty, they simply do not refer. I argue that when such names are used in direct discourse, utterances containing them have truth values but do not express propositions. I also argue that it is a mistake to think that if an utterance of, for example, “Vulcan is a planet” fails to express a proposition, then an utterance of “Le Verrier believed that Vulcan is a planet” cannot express a proposition. The argument applies to claims about fiction, such as “Sherlock Holmes is strong,” and claims about the attitudes of authors and auditors. The upshot is a semantics for fictional statements that provides a satisfying way for direct reference theorists to avoid taking fictional entities to be abstract objects and to accept the commonsense view that what is true in a fiction is ultimately a matter of what is pretended to be the case.     

Associations between a one-shot delay discounting measure and age, income, education and real-world impulsive behavior

There has been discussion over the extent to which delay discounting – as prototypically shown by a preference for a smaller-sooner sum of money over a larger-later sum – measures the same kind of impulsive preferences that drive non-financial behavior. To address this issue, a dataset was analyzed containing 42,863 participants’ responses to a single delay-discounting choice, along with self-report behaviors that can be considered as impulsive. Choice of a smaller-sooner sum was associated with several demographics: younger age, lower income, and lower education; and impulsive behaviors: earlier age of first sexual activity and recent relationship infidelity, smoking, and higher body mass index. These findings suggest that at least an aspect of delay discounting preference is associated with a general trait influencing other forms of impulsivity, and therefore that high delay discounting is another form of impulsive behavior.     

Assessing the automaticity of moral processing: efficient coding of moral information during narrative comprehension

A long-standing theoretical debate concerns the involvement of principled reasoning versus relatively automatic intuitive-emotional processing in moral cognition. To address this, we investigated whether the mental models formed during story comprehension contain a moral dimension and whether this process is affected by cognitive load. A total of 72 participants read stories about fictional characters in a range of moral situations, such as a husband being tempted to commit adultery. Each story concluded with a "moral" or "immoral" target sentence. Consistent with a framework of efficient extraction of moral information, participants took significantly longer to read immoral than moral target sentences. Moreover, the magnitude of this effect was not compromised by cognitive load. Our findings provide evidence of efficient coding of moral dimensions during narrative comprehension and demonstrate that this process does not require cognitively intense forms of principled reasoning.     

The Relationship between Parental Efficacy and Depressive Symptoms in a Diverse Sample of Low Income Mothers

We examined the relationship between parental efficacy and depressive symptoms in a diverse sample of low income mothers. The sample consisted of 607 European American, African American, and Hispanic mothers who participated in The Early Steps Project, a multi-site, longitudinal, preventative intervention study. Parental efficacy was found to be significantly associated with depressive symptoms in the entire sample of low income mothers. Ethnicity moderated results, however, such that parental efficacy was significantly associated with depressive symptoms for European American mothers but was not for the African American and Hispanic mothers. Ethnic differences in the various categories of depressive symptoms (i.e., total, somatic, and psychological) were also explored, with the results showing that African American mothers reported higher levels of depressive symptoms than both European American and Hispanic mothers in each of the categories. The theoretical and clinical implications of these results are discussed.     

Using SMS text messaging for teaching and data collection in the behavioral sciences

Recent interest in university teaching has focused on interactivity in lectures and practical classes, and teachers in several fields have set up systems in which students can interact with the lecturer using mobile-phonebased SMS text messaging. This approach has particular potential in psychology, where students could use SMS messaging as a way of responding in simple psychology experiments or demonstrations. We describe a simple architecture for an SMS-based responding, using an SMS-to-HTTP message relay service, and a PHP/MySQL input-output handler. We describe briefly two experiments we have run using the system. The first experiment examined anchoring effects in an SMS-based auction. The second experiment examined delay discounting, with participants indicating their intertemporal preferences using SMS. Finally, we evaluate the feedback we obtained from students about the practical and conceptual issues surrounding text-message-based responding.
