Infants' detection of visual-tactual discrepancies: asymmetries that indicate a directive role of visual information

Infants' cross-modal functioning was investigated in two studies. In Study 1, 11-month-old infants were confronted with five different visual-tactual discrepancies created with a mirror arrangement. The infants' behavioral reactions to the discrepancies were compared with their behavior on matched control trials with a forced-choice judgement procedure. Infants detected discrepancies in which they saw an egg and felt a cube, saw a fur-covered cube and felt an egg, and saw a cross and felt a fur-covered cube. However, they provided no evidence that they detected discrepancies in which they saw a cube and felt a cross or saw a cube and felt a fur-covered cube. In Study 2, infants were confronted with discrepancies that were the converse of those which seemed to go unnoticed in Study 1: They saw either a cross or a fur-covered cube and felt a plain cube. Both of these new discrepancies were detected according to the forced-choice judgment procedure. The results indicate that texture as well as shape can serve as a basis for cross-modal matching for infants. The asymmetries in cross-modal matching that were observed across Studies 1 and 2 are interpreted as evidence that visual information plays a directive, goal-setting role for infants' manual explorations.     

Diagnosis and prevention of atherosclerotic cerebral infarction

Atherosclerotic disease accounts for approximately 25% of ischemic strokes. Atherosclerotic stroke is caused mainly by embolic events from the carotid artery bifurcation or the aortic arch, although intracranial thrombosis can occur, more often in African Americans, Asians, and diabetes patients. Primary prevention of stroke is critical for patients with risk factors for atherosclerosis, including hypertension, diabetes, smoking and hypercholesterolemia. Stroke can be prevented in patients with established atherosclerotic disease by identification and management of patients with carotid artery stenosis by non-invasive testing. Particular attention must be paid to patients with transient symptoms of brain ischemia.     

Defenses, Personality Structure, and Development: Integrating Psychodynamic Theory Into a Typological Approach to Personality

Psychodynamic theory does not conceptualize motivated unconscious defenses primarily in terms of individual traits. Rather, a person's mechanisms of defense are understood in terms of his or her personality structure and level of psychological development. This paper outlines the way in which this perspective has been integrated into a configural approach to personality assessment. The six-group typology based on the Weinberger Adjustment Inventory (WAI) identifies higher-order personality organization through the intersection of self-reported high/low distress and high/moderate/low self-restraint. The framework incorporates a developmental perspective by assessing affect regulation in conjunction with the internalization of self-regulatory controls. The primary defenses of prototypic members of each of the six groups are highlighted, and hypothesized links to personality traits, stages of ego development, attachment styles, and proneness to specific personality disorders are discussed.     

Tuning the brain by learning and by stimulation of the nucleus basalis

Although it is well-established that the cerebral cortex is a substrate for learning, memory and higher cognitive functions, rather less is known about the mechanisms by which experiences are acquired and stored in the cortex. The role of the basal forebrain cholinergic system (BFCS) in learning-induced plasticity is underlined by a recent report by Kilgard and Merzenich[1]. In this article I will discuss the findings of Kilgard and Merzenich in the context of other developments in our understanding of the BFCS and its role in learning-induced plasticity. However, before the discussion I would like to provide some essential background information.     

A solid-state device for presenting moving shadows

The use of luminescent panels controlled by solid-state circuitry to produce moving shadows is described. Advantages include lack of vibration, noise, and heat.     

Support for religio‐political aggression among teenaged boys in Gaza: Part I: psychological findings

Politically aggressive militant groups usually rely on support from a larger community, although evidence suggests that only some members of that larger community support that aggression. A major subtype of political aggression is that associated with religious differences—or Religio‐Political Aggression (RPA). Little previous research has explored demographic or psychological factors that might distinguish supporters from non‐supporters of RPA. In an exploratory study, we investigated whether factors previously associated with aggression might correlate with support for RPA in the case of the Israeli/Palestinian conflict. During the second intifada, fifty‐two 14‐year‐old Palestinian boys in Gaza completed self‐report measures of life events, emotional status, and political attitudes. Teenaged boys who reported family members having been wounded or killed by the Israeli Defense Forces (IDF) expressed greater support for RPA (t(50)=?2.30, P=.026). In addition, boys who felt their group was treated unjustly reported greater support for RPA compared with those who did not (t(50)=?2.273, P=.027). Implications of these preliminary data are discussed. Aggr. Behav. 36:219–231, 2010. © 2010 Wiley‐Liss, Inc.     

RATS,We Should Have Used Clinton: Subliminal Priming in Political Campaigns

Political strategists decide daily how to market their candidates. Growing recognition of the importance of implicit processes (processes occurring outside of awareness) suggests limitations to focus groups and polling, which rely on conscious self‐report. Two experiments, inspired by national political campaigns, employed Internet‐presented subliminal primes to study evaluations of politicians. In Experiment 1, the subliminal word “RATS” increased negative ratings of an unknown politician. In Experiment 2, conducted during former California Governor Gray Davis's recall referendum, a subliminal photo of Clinton affected ratings of Davis, primarily among Independents. Results showed that subliminal stimuli can affect ratings of well‐known as well as unknown politicians. Further, subliminal studies can be conducted in a mass media outlet (the Internet) in real time and supplement voter self‐report, supporting the potential utility of implicit measures for campaign decision making.     

Age-related differences in acquisition of perceptual-motor skills: working memory as a mediator

Aging is associated with reduced performance on information processing speed, memory, and executive functions tasks. Although older adults are also less apt in acquiring new perceptual-motor skills, it is unclear whether and how skill acquisition difficulties are associated with age-related general cognitive differences. We addressed this question by examining structural relations among measures of cognitive resources (working memory) and indices of perceptual-motor skill acquisition (pursuit rotor and mirror tracing) in 96 healthy adults aged 19-80 years of age. Three competing structural models were tested: a single (common) factor model, a dual correlated factors model, and a hierarchical dual-factor model. The third model provided the best fit to the data, indicating age differences in simple perceptual-motor skill are partially mediated by more complex abilities.
