Threat, high self-esteem, and reactive approach-motivation: Electroencephalographic evidence

High self-esteem predicts personal resilience but also predicts zealous and antisocial reactions to various threats, such as, failure, uncertainty, and mortality salience. The present research supports a basic motivational interpretation of high self-esteem that can account for its resilient but also its zealous and antisocial tendencies. An experimentally manipulated uncertainty threat caused participants with high self-esteem to react with heightened Relative Left Frontal (F7/F8) EEG Activity, a common neural marker of resilient approach-motivation. As predicted by past theorizing on offensive defensiveness (McGregor, 2006), the obtained pattern of neural results mirrors the interaction effect of self-esteem and threat on various antisocial defenses. It is accordingly suggested that reactive approach-motivation processes may help provide an integrative account for some of the angry, zealous, proud, risky, ideological, meaning-seeking, and worldview defense reactions to various threats that have been reported in the social psychological literature.     

Neonatal auditory evoked responses are related to perinatal maternal anxiety

Maternal stress and anxiety during pregnancy are related to negative developmental outcomes for offspring, both physiological and psychological, from the fetal period through early adolescence. This robust relationship is likely to be partly explained by alterations in fetal neurodevelopmental programming, calling for further examination of neurophysiologically-based cognitive markers that may be related to the altered structure–function relationships that contribute to these negative developmental outcomes. The current investigation examined the relationship between perinatal maternal anxiety and neonatal auditory evoked responses (AERs) to mother and stranger voices. Results indicated that neonates of low-anxiety mothers displayed more negative frontal slow wave amplitudes in response to their mother’s voice compared to a female stranger’s voice, while neonates of high-anxiety mothers showed the opposite pattern. These findings suggest that neonates of perinatally anxious mothers may demonstrate neurophysiologically-based differences in attentional allocation. This could represent one pathway to the negative psychological outcomes seen throughout development in offspring of anxious mothers.     

Student outcomes after 1 year of front line staff implementation of the PEAK curriculum

Systems‐level interventions built by behavior analysts often rely on others to implement, and this may be especially true in public education settings where behavior analysts are scarce. This study evaluated the effectiveness of the Promoting the Emergence of Advanced Knowledge Direct Training (PEAK‐DT) curriculum when implemented by school teachers and direct care staff. Thirty‐nine children with autism took part in the study (19 PEAK, 15 control), where the experimental group received applied behavior analytic instruction through the PEAK‐DT curriculum, and the quasi‐randomized control group received training as usual. The PEAK‐DT assessment was first administered to the participants at the onset of the study and again following 1 year. Participants who received PEAK training gained more skills on the PEAK‐DT assessment compared to the control group (PEAK: M = 16.0, SD = 17.8; control: M = 6.1, SD = 14.4, F(1,33) = 10.66, p < .05), suggesting that systems level implementation of behavior analytic procedures can be effective in teaching language skills as prescribed in a packaged curriculum designed by behavior analysts.     

The Expansion View of Thick Concepts

This paper proposes a new Separabilist account of thick concepts, called the Expansion View (or EV). According to EV, thick concepts are expanded contents of thin terms. An expanded content is, roughly, the semantic content of a predicate along with modifiers. Although EV is a form of Separabilism, it is distinct from the only kind of Separabilism discussed in the literature, and it has many features that Inseparabilists want from an account of thick concepts. EV can also give non-cognitivists a novel escape from the Anti-Disentangling Argument. §I explains the approach of all previous Separabilists, and argues that there's no reason for Separabilists to take this approach. §II explains EV. §III fends off objections. And §IV explains how non-cognitivist proponents of EV can escape the Anti-Disentangling Argument.     

Assessing students' use of optional online lecture reviews

Online practice quizzes can be used to supplement instruction in the classroom. Such quizzes can engage retrieval practice, thereby improving learning and retention. However, despite their potential benefits, recent work suggests that students typically underutilize online practice quizzes. This article reports an observational classroom study, in which students were provided optional online reviews throughout the semester. The reviews could be accessed in test format, in which students were given multiple-choice questions and provided correct answer feedback, or in read format in which students were given the same questions and were shown the correct answers. Students who used the test format performed better on exams than students who used the read format or did not use the reviews. Nevertheless, the massive majority of the online reviews (approximately 88%) were not completed, highlighting the tendency for students to underutilize optional online reviews.     

Investigations of closure processes: What source-monitoring judgments suggest about what is “closing”

On many occasions, the perception of an object is based on incomplete information because portions of the object are occluded from view. Nevertheless, people are able to identify an occluded object, suggesting that the identification is mediated by the activation of completion processes which “fill in” the missing information. Although these completion processes are invoked as causal mechanisms for many phenomena, the processes mediating the “completion” have not been specified. The present experiments tested two potential explanations for closure processes. In each experiment, participants were presented with pictures, complete or incomplete in form, and, on a surprise source-monitoring task, they were then asked to remember whether pictures had been presented complete or incomplete in form. Whether viewing pictures of objects, faces, or camouflaged objects, participants showed a pronounced tendency to claim that incomplete pictures were actually presented complete in form. This bias was evident after the participants described functions for objects (Experiments 1, 1A, and 2), after they evaluated properties of faces (Experiment 4), and after they searched for objects hidden in a complex scene (Experiment 5). However, this bias was not evident after they simply named objects portrayed in pictures (Experiment 3). This bias is interpreted as evidence for the activation of implicit imaginal processing. The results of these experiments are informative in their contribution to our understanding of the bases of closure, an intuitively appealing notion frequently invoked to account for object identification, but, as yet, not fully understood.
