Bimanual handedness in adults who stutter

25 adult stutterers and 29 nonstutterers who were right-handed as defined by a positive Laterality Quotient on the Edinburgh Handedness Inventory were compared with respect to their pattern of hand use in performing seven common tasks that involve bimanual cooperation. Among the stutterers was a higher proportion of participants who showed anomalies in how they carried out the two tasks that required synchronous manipulation by the two hands. On two other tasks that required speeded performance, the groups were similar in dealing playing cards with the right or left hands, but the stutterers were slower than nonstutterers and did not show a right-hand advantage on a task requiring removal of a nut from a bolt. The results were interpreted as indicating difficulty by stutterers in carrying out synchronously different response elements of motoric tasks.     

Impure Agency and the Just War

Feminist critiques of intention challenge some aspects of traditional just war reasoning, including the criteria of right intention and discrimination (particularly as interpreted using the doctrine of double effect). I take note of these challenges and propose some directions just war reasoners might take in response. First, right intention can be evaluated more accurately by judging what actors in war actually do than by attempting to uncover inward dispositions. Assessing whether agents in war have taken due care to minimize foreseeable collateral damage, avoided intentional targeting of noncombatants, corrected previous mistakes in their later actions, and taken responsibility to repair unintended damage they cause are examples of ways in which just war reasoners can evaluate intention by looking at actions.     

The role of number words: the phonological length effect in multidigit addition

We explored the role of phonological representations of number words in exact calculation. The reaction times and accuracy of responses in multidigit addition problems were compared across three groups of participants (young healthy, older healthy, and 3 patients with severe aphasia) and two types of addition problems: phonologically long in English (containing the bisyllabic number word ??seven??) and short in English (monosyllabic number words??e.g., ??six??). Older healthy participants were significantly faster and more accurate in calculation than younger healthy participants. The older participants showed no evidence of a phonological length effect. However this effect was apparent in the younger adults, with longer reaction times on phonologically long problems. Furthermore, there was an association between the presence of a phonological length effect and the overall speed of response, suggesting that less proficient calculators were more reliant on phonological mediation of performance. The aphasic participants retained the ability to complete multidigit additions and were as accurate as the younger healthy group, although the response times of two of the 3 patients were slow. The aphasic participants varied with regard to the presence of a phonological length effect. Two participants showed no evidence of phonological mediation, while 1 displayed a phonological length effect. The results suggest that language resources are not mandatory for exact addition, although they may be used to scaffold math performance in less competent calculators. Evidence of phonological mediation of performance in aphasic participants may provide insight into the integrity or otherwise of inner speech in severe aphasia.     

Understanding the power of the picture: the effect of image content on emotional and political responses to terrorism

Viewing images of terrorism can have a powerful impact on individuals' emotional and political responses, yet little is known about the psychological processes underlying these effects. We hypothesized that the content of terrorism images will shape viewers' appraisals of the event, which will elicit specific emotions and political attitudes. British citizens viewed photographs of the 2005 London bombings, either focusing on victims or terrorists. Exposure to images of victims increased appraisals of victim suffering, which predicted feelings of sympathy. Exposure to images of terrorists increased appraisals of terrorists as dangerous, which predicted fear; and of the attack as unjust, which predicted anger. Each emotion predicted support for a distinct counterterrorism policy. Theoretical and practical implications are discussed.     

THE EYE OF THE BEGETTER: PREDICTING INFANT ATTACHMENT DISORGANIZATION FROM WOMEN'S PRENATAL INTERPRETATIONS OF INFANT FACIAL EXPRESSIONS

Infant–caregiver attachment disorganization has been linked to many long‐term negative psychosocial outcomes. While various prevention programs appear to be effective in preventing disorganized attachment, methods currently used to identify those at risk are unfortunately either overly general or impractical. The current investigation tested whether women's prenatal biases in identifying infant expressions of emotion—tendencies previously shown to relate to some of the maternal variables associated with infant attachment, including maternal traumatization, trauma symptoms, and maternal sensitivity—could predict infant attachment classification at 18 months postpartum. Logistic regression analyses revealed that together with women's adult history of high betrayal traumatization, response concordance with a normative reference sample in labeling infant expressions as negatively valenced, and the number of infant facial expressions that participants classified as “sad” and “angry” predicted subsequent infant attachment security versus disorganization. Implications for screening and prevention are discussed.     

The Suppression and Justification of Prejudice as a Function of Political Orientation

Politically conservative (versus liberal) individuals generally report more prejudice towards various low‐status out‐groups. Three studies examined whether prejudice suppression factors—specifically, internal and external motivation to suppress (IMS and EMS, respectively) prejudice—can help explain the relationship between political orientation and prejudice. Study 1 showed that IMS and EMS partially mediated the relationship between political orientation and affective prejudice towards Arabs. Study 2 demonstrated that when justification [right‐wing authoritarianism (RWA) and social dominance orientation] and suppression (IMS and EMS) factors are simultaneously tested as mediators, only RWA partially mediated the relationship between political orientation and prejudice towards deviant (e.g. gay men) out‐groups, whereas RWA and IMS fully mediated the relationship between political orientation and prejudice towards derogated out‐groups (e.g. Blacks). Intriguingly, IMS rendered social dominance orientation effects non‐significant for derogated out‐groups. Study 3 showed that anticipating an out‐group interaction (with a Black or lesbian confederate) diminished the mediational contribution of IMS in the political orientation–prejudice relationship because of increased IMS among participants; yet the increases in IMS did not completely eliminate differences in prejudice as a function of political orientation. Ultimately, these three studies demonstrate that suppression (in addition to justification) factors do help explain the relationship between political orientation and prejudice.

Recollection Training and Transfer Effects in Older Adults: Successful Use of a Repetition-Lag Procedure

Abstract

We examined an approach aimed at training consciously-controlled recollection, introduced by Jennings and Jacoby (2003) Jennings, J. M. and Jacoby, L. L. 2003. Improving memory in older adults: Training recollection. Neuropsychological Rehabilitation, 13: 417–440. [CSA][CROSSREF][Taylor & Francis Online], [Web of Science ®] , [Google Scholar], for its ability to replicate and generalize. A continuous recognition task, requiring recollection to identify the occurrence of repeated items over gradually increasing lag intervals (number of intervening items between the first and second presentation of a repeated word), was given to a group of older adults twice a week for three weeks. Pre-and-post training performance was assessed on multiple measures and compared with a recognition practice and no contact control group. Recollection training proved successful; accurate identification of repeated items increased across a lag interval of 2 to 18 intervening items. Post-training gains following recollection training were found on n-back, self-ordered pointing, source discrimination and digit symbol substitution, but not with reading span or the CVLT-II. No changes were identified in the other groups. Gains from recollection training seem to transfer successfully in older adults.
