Stereotypic horses (Equus caballus) are not cognitively impaired

Animal Cognition - Stereotypies in animals are thought to arise from an interaction between genetic predisposition and sub-optimal housing conditions. In domestic horses, a well-studied...     

The effects of extending the CS-UCS interval on the effectiveness of the conditioning treatment for nocturnal enuresis

Previous studies of the “conditioning method” of enuresis treatment have confounded the effects of conditioning with those of nonspecific psychotherapeutic aspects of the procedure. The present study compared three groups of enuretic children: (1) under the conventional bell-light conditioning procedure; (2) under a similar procedure, but which involved a three-minute delay between wetting and alarm, and (3) under no-treatment conditions. Double-blind precautions were used. Results suggested that conditioning effects improvement over and above that effected by nonspecific influences. The findings are qualified by large variances in improvement, and by premature termination of the experiment.     

The Semantic Drift of Quotations in Blogspace: A Case Study in Short‐Term Cultural Evolution

We present an empirical case study that connects psycholinguistics with the field of cultural evolution, in order to test for the existence of cultural attractors in the evolution of quotations. Such attractors have been proposed as a useful concept for understanding cultural evolution in relation with individual cognition, but their existence has been hard to test. We focus on the transformation of quotations when they are copied from blog to blog or media website: by coding words with a number of well‐studied lexical features, we show that the way words are substituted in quotations is consistent (a) with the hypothesis of cultural attractors and (b) with known effects of the word features. In particular, words known to be harder to recall in lists have a higher tendency to be substituted, and words easier to recall are produced instead. Our results support the hypothesis that cultural attractors can result from the combination of individual cognitive biases in the interpretation and reproduction of representations.     

The Theory of Planned Behavior: Some Measurement Issues Concerning Belief-Based Variables

The theory of planned behavior presents clear operational definitions of attitudes, subjective norm, perceived behavioral control, and each of their corresponding belief-based measures. Theoretically, the direct and indirect measures of a given construct must be closely correlated. Empirical results, however, indicate that this is not always the case. In the present study, 2 of the factors that could be responsible for this situation-namely, the scaling of the variables defining each belief-based construct and the adequacy of using an expectancy-value model within the belief-based measures-were verified among a data set of 16 studies concerned with the application of the theory of planned behavior to the field of health. The results indicate that the scaling method used affected the correlation coefficients between indirect and direct measures. However, the face validity of these scaling methods must be demonstrated. The results also support the idea that, in most cases, using the expectancy-value model is no better than using only one arm of the belief-based measure.     

INSTRUMENTAL AND EXPRESSIVE TRAITS, TRAIT STEREOTYPES, AND SEXIST ATTITUDES What Do They Signify?

College students rated die typical male and female student and themselves on 22 instrumental (I) and 16 expressive (E) items from the PAQ (Spence & Helmreich, 1978) and the BSRI (Bern, 1974), as well as on the BSRI items "masculine" and "feminine." They also completed measures of gender stereotypes and sexist attitudes. Significant gender stereotypes were found on all but two I and E items in both genders. Significant gender differences in self-report were found on all the E items but on only 41% of the I items, confirming our hypotheses that societal changes have led women to develop more agentic self-conceptions. The pattern of relationships found between the self-report, stereotype, and attitude measures supports the utility of a multidimensional approach to gender. Responses to the items "masculine" and "feminine" confirm the implications of our hypothesis that these items primarily assess men's and women's basic sense of gender identity.     

What We Talk About Matters: Content Moderates Cognitive Depletion in Interracial Interactions

The antecedents and consequences of intergroup interactions have been well studied, but interaction content—what partners actually talk about—has not. In the experiment we report here, interaction content moderated well-documented self-regulation effects (i.e., cognitive depletion) among White participants interacting with a Black partner. Specifically, White individuals participated in a video email interaction with an ostensible Black or White partner who broached topics systematically varying in intimacy. Greater cognitive depletion was evident after interacting with a Black partner relative to a White partner, but only after discussing more intimate topics. When conversation topics aligned with Whites’ preferences to avoid intimacy in interracial interactions, depletion effects were reduced. Thus, interaction content, which has been largely ignored in intergroup interaction research, has important implications for intergroup interaction.     

Retraction statement: When nothing compares to me: how defensive motivations and similarity shape social comparison effects

The following article from European Journal of Social Psychology, “When nothing compares to me: How defensive motivations and similarity shape social comparison effects” by Diederik A. Stapel and Camille S. Johnson, published online on 26 September 2006 in Wiley Online Library ( wileyonlinelibrary.com ), has been retracted by agreement between the co‐author, the journal Editor in Chief, Tom Postmes, and John Wiley and Sons Ltd. The retraction has been agreed following the results of an investigation into the work of Diederik A. Stapel ( https://www.commissielevelt.nl/ ). The Levelt Committee has determined that this article contained data that was fabricated by Diederik A. Stapel. His co‐author was unaware of his actions, and not in any way involved.

Top-down processing modulates older adults’ susceptibility to noise

The present study examined older and younger adults’ ability to use top-down processes to mitigate the effects of display noise during simple feature, visual search. As display noise levels increased, older adults (age 60–74 years, n = 32) exhibited greater top-down search reaction time (RT) benefits (bottom-up minus top-down search RT), compared to younger adults (age 18–27, n = 32). Older adults’ ability to mitigate the effects of noise was further assessed with RT variability, as measured by intra-individual standard deviations across trials. Older adults again exhibited larger top-down benefits (i.e., less RT variability) compared to younger adults, and more so when display noise was present vs. absent. These results suggest a sparing of top-down processes with age (Madden, Whiting, Spaniol, & Bucur, 2005; Psychology and Aging, 20, 317), and that top-down processes in older adults enhance search efficiency by optimizing signal-to-noise ratios.     

The Failure of the Bona Fide Occupational Qualification in Cross‐Gender Prison Guard Cases: A Problem beyond Equal Employment Opportunity

Knowing the theory of gender that a court is using to understand and assess the issues in a case is vital to ensuring that women are afforded their full rights under the law. Unfortunately, courts often do not explicitly state what understanding of gender is informing their decisions. An exception is found in employment law: specifically, the bona fide occupational qualification (BFOQ) exception to Title VII of the Civil Rights Act, which allows employers to engage in sex‐based discrimination in those instances in which the sex of the employee is a reasonably necessary qualification for the job. In these cases, because the court must analyze how “manness” or “womanness” impacts one's qualification to hold certain kinds of employment, the court must articulate its understanding of gender. This paper examines two BFOQ cases in the cross‐gender prison guard context, those cases in which an individual of one sex seeks to guard inmates of the opposite sex. In these cases the courts created a theory of gender that posits men and women as different in kind. The theory developed in this line of cases is an attack on Title VII protections and a potential barrier to women's equality under the law.
