Book notes

There is a standard objection against purported explanations of how a language L can express the notion of being a true sentence of L. According to this objection, such explanations avoid one paradox (the Liar) only to succumb to another of the same kind. Even if L can contain its own truth predicate, we can identify another notion it cannot express, on pain of contradiction via Liar-like reasoning. This paper seeks to undermine such ‘revenge’ by arguing that it presupposes a dubious assumption about the linguistic expression of concepts. Successful revenge would require that there be a notion other than truth that plays the same role with respect to concept-expression that truth is naturally thought to play before we are confronted with the Liar paradox.

La vendetta, oh, la vendetta?Revenge, oh revenge

è un piacer serbato ai saggi.?is a pleasure reserved for the wise.

[…] il fatto è serio …?[…] the case is serious …

ma credete si farà.?but trust me, I'll take care of it.

Se tutto il codice dovessi volgere,?If I have to turn over the whole law-book,

se tutto l'indice dovessi leggere,?if I have to read through the whole index,

con un equivoco, con un sinonimo?with an equivocation, with a synonym

qualche garbuglio si troverà.?I'll find some way to tangle things up.

[…] il birbo Figaro vinto sarà.?[…] that rascal Figaro will be defeated.

Role of Group Affiliation and Gender on Attitudes Toward Women in the Military

The current study examined attitudes of West Point cadets (N = 218), Reserve Officer Training Corps (ROTC) cadets (N = 509), and non-military-affiliated students from civilian colleges (N = 598) toward a variety of roles that women may serve in the military. Respondents were queried whether a woman “should” or “should not” serve in the following military jobs: jet fighter pilot, truck mechanic, nurse in a combat zone, typist in the Pentagon, commander of a military installation, hand-to-hand combat soldier, jet transport pilot, air defense gunner, and crew member on a combat ship. A metric based on a sum of approval across all jobs indicated that women were significantly more approving than men; civilian college students were more approving than ROTC cadets; and West Point cadets showed the lowest overall approval.     

Predictors of Support for Women in Military Roles: Military Status,Gender, and Political Ideology

The repeal of combat restrictions by gender raises the importance of understanding factors related to the acceptance of women serving in the full range of military jobs. Previous research shows military affiliated cadets, especially males, are substantially less approving of women serving in military jobs, especially those involving exposure to direct combat or command positions, than are other college students. The current study extends these findings by considering political ideology in addition to gender and military affiliation, as related to attitudes toward women’s roles in the military overall and in combat roles in particular. Survey data from Service Academy cadets (n = 3,116), Reserve Officer Training Corps (ROTC) cadets (n = 1,367), and nonmilitary affiliated college students (n = 2,648), provided measures of whether a woman should or should not be allowed to serve in 9 different military job areas. In addition to overall approval, a scale for combat jobs was created from a subset of 4 of the jobs. Regression analysis indicated that once gender, political party, political position (left/right), and attitudes toward mothers in the workforce overall were controlled, type of college did not add to the prediction of acceptance of women in various military roles. In general, nonmilitary affiliated respondents, women, and those identifying as Democrat offered higher approval scores. Our findings suggest more aggressive programs, designed to educate and socialize these future leaders about women’s roles in the military, may require development.     

Investigating the Moderating Role of Cultural Practices on the Effect of Selection Fairness Perceptions

Utilizing a sample of applicants to positions in a global corporation, we examined whether cultural practices moderate the effect of selection fairness perceptions on organizational attractiveness and job choice. Positive relationships were anticipated between fairness perceptions and outcomes, and performance orientation and uncertainty avoidance cultural practices were hypothesized to moderate the effects of structural and information sharing perceptions, respectively. Structural fairness perceptions were positively associated with both outcomes, but information‐sharing perceptions were significantly related only to organizational attractiveness. National variability in the effect of selection fairness perceptions was observed only for the effect of structural perceptions on organizational attractiveness. Performance orientation moderated this effect such that the strongest relationship was seen among applicants from more performance‐oriented countries.     

Dimensions of the Integration of Faith and Learning An Interactionist Perspective

This article responds to the challenge to ‘unpack’ the ‘slogan’ of fait/learning integration. It discusses three ways by which the topic may be approached in academic discourse. These include institution building, the deconstruction of dichotomies and dualities, and the integration of creed and deed. While our discussion in regards to institution building and the integration of creed and deed constitutes an extension of current constructs, we advance the notion of the deconstruction of dichotomies and dualities as a new approach to the faith/learning integration theme.     

Knowledge on the line: Manipulating beliefs about the magnitudes of symbolic numbers affects the linearity of line estimation tasks

It has been suggested that differences in performance on number-line estimation tasks are indicative of fundamental differences in people’s underlying representations of numerical magnitude. However, we were able to induce logarithmic-looking performance in adults for magnitude ranges over which they can typically perform linearly by manipulating their familiarity with the symbolic number formats that we used for the stimuli. This serves as an existence proof that individuals’ performances on number-line estimation tasks do not necessarily reflect the functional form of their underlying numerical magnitude representations. Rather, performance differences may result from symbolic difficulties (i.e., number-to-symbol mappings), independently of the underlying functional form. We demonstrated that number-line estimates that are well fit by logarithmic functions need not be produced by logarithmic functions. These findings led us to question the validity of considering logarithmic-looking performance on number-line estimation tasks as being indicative that magnitudes are being represented logarithmically, particularly when symbolic understanding is in question.     

The Relational SNARC: Spatial Representation of Nonsymbolic Ratios

Recent research in numerical cognition has begun to systematically detail the ability of humans and nonhuman animals to perceive the magnitudes of nonsymbolic ratios. These relationally defined analogs to rational numbers offer new potential insights into the nature of human numerical processing. However, research into their similarities with and connections to symbolic numbers remains in its infancy. The current research aims to further explore these similarities by investigating whether the magnitudes of nonsymbolic ratios are associated with space just as symbolic numbers are. In two experiments, we found that responses were faster on the left for smaller nonsymbolic ratio magnitudes and faster on the right for larger nonsymbolic ratio magnitudes. These results further elucidate the nature of nonsymbolic ratio processing, extending the literature of spatial–numerical associations to nonsymbolic relative magnitudes. We discuss potential implications of these findings for theories of human magnitude processing in general and how this general processing relates to numerical processing.     

Influence of age, sex, and family on Type A and hostile attitudes and behaviors.

We describe the influence of age, sex, and family on Type A and hostility indices that have been related to rates of coronary heart disease (CHD). The sample consisted of 120 girls and 95 boys (ages 6 to 18 years) and 141 women and 120 men (ages 31 to 62 years) from 142 families residing in an upper middle class community. Results showed little familial aggregation of Type A and hostility. Adults had higher Structured Interview (SI) Potential for Hostility ratings than did children, whereas children had higher Minnesota Multiphasic Personality Inventory (MMPI)-derived Hostility scores and SI Anger-In ratings than did adults. Male adults and male children had higher SI Potential for Hostility ratings and MMPI-derived Hostility scores than did their female counterparts. The heightened hostility of males may account, in part, for their heightened risk of CHD relative to females'.     

Mice with targeted genetic reduction of GABA(A) receptor alpha1 subunits display performance differences in Morris water maze tasks

Recent research has begun to demonstrate that specific subunits of GABA(A) receptors may be involved in the normal expression of specific behaviors. The present research used mice with GABA(A) receptors whose alpha1 subunits contained mutations of serine 270 to histidine and leucine 277 to alanine in the TM2 region. The purpose was an attempt to examine the possible role that this particular subunit may have in learning the spatial and nonspatial version of the Morris water maze task. Mutant animals, compared to controls, displayed elevated levels of pool circling in both the spatial task and the nonspatial task. These results suggested that normal performance of the spatial and nonspatial water maze tasks may be dependent upon a natural alpha1 subunit array.     

Stored word sequences in language learning: the effect of familiarity on children's repetition of four-word combinations

Recent accounts of the development of grammar propose that children remember utterances they hear and draw generalizations over these stored exemplars. This study tested these accounts' assumption that children store utterances as wholes by testing memory for familiar sequences of words. Using a newly available, dense corpus of child-directed speech, we identified frequently occurring chunks in the input (e.g., sit in your chair) and matched them to infrequent sequences (e.g., sit in your truck). We tested young children's ability to produce these sequences in a sentence-repetition test. Three-year-olds (n= 21) and 2-year-olds (n= 17) were significantly more likely to repeat frequent sequences correctly than to repeat infrequent sequences correctly. Moreover, the 3-year-olds were significantly faster to repeat the first three words of an item if they formed part of a chunk (e.g., they were quicker to say sit in your when the following word was chair than when it was truck). We discuss the implications of these results for theories of language development and processing.
