Automatically activated facets of ageism: Masked evaluative priming allows for a differentiation of age‐related prejudice

This study investigated the automatic activation of ageism by using a go/no‐go version of the masked evaluative priming task. Pictures of younger persons, of older persons in everyday contexts, and of older persons depicting age‐related conditions of decline were used as masked primes that preceded positive and negative target adjectives conveying either other‐relevant valence (e.g., just and mean) or possessor‐relevant valence (e.g., serene and lonely). The evaluative priming effect (denoting relative negativity of old‐everyday primes in comparison with younger primes) was significant, as hypothesized, only for possessor‐relevant targets. It was not moderated by explicit ageism. A second priming index (denoting relative negativity of old‐decline primes in comparison with old‐everyday primes) predicted, however, explicit ageism. Again, this result was, as expected, constrained to the index based on possessor‐relevant targets. This study provides further evidence that prejudice in terms of automatic evaluations of social stimuli can be more fine grained beyond a mere one‐dimensional positive–negative differentiation.

Intergroup anxiety from the self and other: Evidence from self‐report,physiological effects,and real interactions

Intergroup anxiety has become important in understanding the success or failure of intergroup contact. In this paper, we suggest that intergroup anxiety is made up from two constructs: self‐anxiety (anxiety over thinking or doing something that is prejudiced) and other‐anxiety (anxiety that the other might do something to you). Over four studies, we show how these two dimensions have different correlates and independently predict psychophysiological reactivity to an intergroup interaction. Other‐anxiety was associated with negative intergroup attitudes and negative affect. In contrast, self‐anxiety had no simple relationship with conventional measures of intergroup attitudes but was associated with a flattening of responses that were indicative of freezing (Study 3) and simultaneous approach and avoidance (Study 4). We suggest that whereas other‐anxiety is associated with negative affect and avoidance, self‐anxiety is associated with ‘freezing’ responses to intergroup interaction. Thus, the distinction between these two constructs has important repercussions. Copyright © 2011 John Wiley & Sons, Ltd.     

The neural basis of syntactic deficits in primary progressive aphasia

Patients with primary progressive aphasia (PPA) vary considerably in terms of which brain regions are impacted, as well as in the extent to which syntactic processing is impaired. Here we review the literature on the neural basis of syntactic deficits in PPA. Structural and functional imaging studies have most consistently associated syntactic deficits with damage to left inferior frontal cortex. Posterior perisylvian regions have been implicated in some studies. Damage to the superior longitudinal fasciculus, including its arcuate component, has been linked with syntactic deficits, even after gray matter atrophy is taken into account. These findings suggest that syntactic processing depends on left frontal and posterior perisylvian regions, as well as intact connectivity between them. In contrast, anterior temporal regions, and the ventral tracts that link frontal and temporal language regions, appear to be less important for syntax, since they are damaged in many PPA patients with spared syntactic processing.     

Perseveration in congenitally blind children: Effects of luminous and acoustic targets on a modified A-not-B task

The purpose of this study was to determine whether or not blind children perseverate during a modified Piagetian A-not-B reaching task, with conditions that employ luminous AB targets and acoustic AB targets. Ten congenitally blind children, ages 1–4 years, with residual vision for light, took part in this study. Behavioral and kinematic data were computed for participants’ reaches, performed in six A trials and in two B trials, in both stimulus conditions. All of the children perseverated in the luminous condition, and none of them perseverated in the condition using acoustic targets. The children tilted their heads in the direction of the target as they reached towards it. However, this coupling action (head-reaching) occurred predominantly in the A trials in the acoustic condition. In the luminous condition, in contrast to the acoustic condition, the children took longer times to initiate the reaching movement. Also, in the luminous condition, the children explored the target surroundings, unlike the acoustic condition, in which they reached straight ahead. For these blind children, sound was more relevant to reaching than was the luminous stimulus. The luminous input caused perseveration in congenitally blind children in a similar way that has been reported in the literature for typically-developing, sighted infants, ages 8–12 months, performing A-not-B tasks with visual inputs.     

Investigating hemispheric lateralization of reflexive attention to gaze and arrow cues

Recent studies have demonstrated that central cues, such as eyes and arrows, reflexively trigger attentional shifts. However, it is not clear whether the attentional mechanisms induced by these two cues are similar or rather differ in some important way. We investigated hemispheric lateralization of the orienting effects induced by the two cue types in a group of 48 healthy participants comparing arrows and eye gaze as central non-predictive cues in a discrimination task, in which a target stimulus was briefly presented in one of two peripheral positions (left or right of fixation). As predicted by neuropsychological data, reflexive orienting to gaze cues was only observed when the target was presented in the left visual field, whereas reflexive orienting to arrow cues occurred for targets presented in both left and right visual fields.     

Early predictors of high school mathematics achievement

Identifying the types of mathematics content knowledge that are most predictive of students' long-term learning is essential for improving both theories of mathematical development and mathematics education. To identify these types of knowledge, we examined long-term predictors of high school students' knowledge of algebra and overall mathematics achievement. Analyses of large, nationally representative, longitudinal data sets from the United States and the United Kingdom revealed that elementary school students' knowledge of fractions and of division uniquely predicts those students' knowledge of algebra and overall mathematics achievement in high school, 5 or 6 years later, even after statistically controlling for other types of mathematical knowledge, general intellectual ability, working memory, and family income and education. Implications of these findings for understanding and improving mathematics learning are discussed.     

Acquired dyslexia in three writing systems: study of a Portuguese-Japanese bilingual aphasic patient

The Japanese language is represented by two different codes: syllabic and logographic while Portuguese employs an alphabetic writing system. Studies on bilingual Portuguese-Japanese individuals with acquired dyslexia therefore allow an investigation of the interaction between reading strategies and characteristics of three different writing codes. The aim of this study was to examine the differential impact of an acquired brain lesion on the reading of the logographic, syllabic and alphabetic writing systems of a bilingual Portuguese-Japanese aphasic patient (PF). Results showed impaired reading in the logographic system and when reading irregularly spelled Portuguese words but no effects on reading regular words and nonwords in syllabic and alphabetic writing systems. These dissociations are interpreted according to a multi-route cognitive model of reading assuming selective damage in the lexical route can result in acquired dyslexia across at least three different writing codes.     

The NK3 receptor agonist senktide ameliorates scopolamine-induced deficits in memory for object, place and temporal order

Senktide, a potent neurokinin-3 receptor (NK₃-R) agonist, increases acetylcholine (ACh) release in the striatum, the prefrontal cortex (Schäble et al., 2011), the amygdala and hippocampus, presumably via postsynaptic mechanisms. A promnestic action of NK₃-R agonists has been described in a variety of learning/memory tasks. The memory-enhancing effects of NK₃-R agonists and their activating influence on ACh suggest a possible role of the NK₃-R in learning and memory via cholinergic modulation. Deterioration of the cholinergic system in the basal forebrain has been associated with learning and memory deficits and cholinergic agents have promnestic effects in a variety of learning paradigms. The anticholinergic drug, scopolamine, a muscarinic ACh receptor antagonist, incurs deficits in a variety of learning tasks and provides a useful tool to investigate the role of the cholinergic systems in mechanisms underlying learning and memory. The aim of this study was to ascertain the effect of the NK₃-R agonist, senktide, in the scopolamine-induced deficit model. We hypothesized that senktide treatment would attenuate scopolamine-induced (subcutaneous – s.c. 0.75 mg/kg) memory impairment in three novelty preference paradigms based on spontaneous object exploration: namely object recognition, object–place recognition and object recognition for temporal order. Administration of senktide reversed the scopolamine-induced memory deficits by re-establishing object recognition (s.c. 0.2 mg/kg), object–place recognition (0.2 and 0.4 mg/kg), as well as object recognition for temporal order (0.4 mg/kg) in adult Wistar rats. These results indicate memory enhancing effects of senktide in animals subjected to scopolamine-induced memory impairments and indicate that the promnestic action of NK₃-R agonists is mediated by muscarinic cholinergic mechanisms.     

Family functioning and socioaffective competencies of children in the beginning of schooling

The aim of this short-term longitudinal study, based on the system theory, was to test the association between different aspects of family functioning of preschoolers and their socioaffective competencies at the end of the first grade. The total sample included 278 children (137 boys and 141 girls) and their families. The analysis of variance results regarding the aspects of family cohesion and harmony showed that preschoolers from more cohesive families display more social skills, while those from more conflicting families display more externalizing behavior problems (aggression and irritability). With respect to the family's ability to resolve problems, it was observed that, especially for middle and upper class families, this aspect is associated with better social skills and fewer internalized behavior problems. Overall, results of the present study suggest that the family functioning at early stage might influence children's abilities to regulate their emotions and to establish/maintain important relationships with peers and teachers in their early school years.     

Trial-based psychotherapy and the efficacy of trial-based thought record in changing unhelpful core beliefs and reducing self-criticism

IntroductionThe best prevention against relapse results when patients are taught to restructure negative core beliefs (CBs). Efficacy of the trial-based thought record (TBTR) in decreasing the credit given by patients to negative CBs and corresponding emotions was evaluated.MethodPatients (n = 166) were submitted to a simulation of a legal trial to assess their adherence to negative CBs and corresponding emotions after each cognitive therapy technique incorporated by TBTR. RESULTS: Significant reductions existed in percent values after the first and second defense attorney pleas, as well as after jury's verdict and initial preparation for the appeal (p < 0.001), relative to the investigation phase. Significant differences also emerged between the defense attorney's first and second pleas and between the defense attorney's second plea and jury's verdict, as well as preparation for the appeal (p < 0.001). There was no significant difference between percentages presented by patients submitted to TBTR used in the empty chair format relative to the conventional format. Similarly, there was no difference between outcomes, regardless of therapists' level of exposure to TBTR.ConclusionTBTR may help patients reduce attachment to negative CBs and corresponding emotions. Outcomes were significantly favorable regardless of the format use and therapists' level of exposure to TBTR.
