Amnesia by post-training infusion of glutamate receptor antagonists into the amygdala, hippocampus, and entorhinal cortex.

The blockers of glutamate receptors, aminophosphonovaleric acid (AP5) (5.0 micrograms) and cyano-nitroquinoxaline-dione (CNQX) (0.5 microgram), were infused bilaterally into the amygdala, dorsal hippocampus, or entorhinal cortex of rats through indwelling cannulae 0, 90, 180, or 360 min after step-down inhibitory avoidance training. Animals were tested for retention 24 h after training. In the amygdala or hippocampus, AP5 was amnestic when given 0 min after training and CNQX was amnestic when given 0, 90, or 180 min after training. In the entorhinal cortex, AP5 was amnestic when given 90 or 180 min after training and CNQX had no effect. The results suggest that a phenomenon sensitive first to AP5 and then to CNQX in the amygdala and hippocampus, probably long-term potentiation (LTP), is crucial to post-training memory processing. LTP in these two structures could underlie their role in memory consolidation and could explain the late involvement of the entorhinal cortex in post-training memory processing.     

Linearization strategies during language production

The two experiments reported here were designed to examine discourse planning during language production. Following the work of Levelt (1981, 1982), participants were shown simple networks consisting of two branches, and their task was to describe the networks. The two branches of the networks differed in either length or complexity; the dependent measure was participants’ decisions to describe the left or right branch first. The experiments showed that speakers preferred to describe a less complex branch before a more complex branch and preferred to describe a shorter branch before a longer branch. Levelt’s minimal-load principle is invoked to explain these results, along with the principle of incrementalism (Levelt, 1989). Discussion focuses on the possibility that incrementalism in production is useful to both the speaker and the listener.

Zika virus and pregnant women: A psychological approach

Zika virus presents risk of physical harm to pregnant women, but the fear of infection is also affecting women around the world. There is a gap in the research on Zika virus in the areas involving the impact on the psychosocial well-being of pregnant women. Therefore, this study is aimed at the investigation of the psychosocial adjustment of pregnant women to the risks of Zika virus infection during pregnancy. We investigated 14 pregnant women who were classified in three different groups: six in the first trimester, five in the second trimester and three in the third trimester, aged from 28 to 40 years (33.43 ± 3.76 years). Content analysis was used to interpret data. Our results show that the psychosocial adjustment of participants was significantly negative and included five aspects: (1) negative feelings, (2) changes in family planning, (3) adopting new customs (avoiding places of risk, use of specific clothes and use of repellent), (4) changed attitudes regarding body image and (5) feeling of external demand regarding prevention. The fear of Zika virus infection and all its associated risks have a negative biopsychosocial impact on the pregnant women in this study.     

Are you willing to pay the price? The impact of corporate social (ir)responsibility on consumer behavior towards national and foreign brands

This research examines how the country of origin (national vs. foreign) affects the relation between corporate social responsibility (CSR) and consumers' willingness to pay and purchase intention. In the study, we adopted a first‐price sealed bid auction approach, using money in a “real‐world” setting. The results showed that CSR/corporate social irresponsibility (CSIR) affects consumer behavior and, particularly, consumers' willingness to pay and purchase intention. The study supports both the moderation hypothesis of country of origin in the relationship between CSR/CSIR and willingness to pay and between CSR/CSIR and purchase intention. In the globalization context, these results have important implications for brands' communication and marketing strategy and can stimulate important insights in organizations. Future research directions and limitations are also discussed. Copyright © 2016 John Wiley & Sons, Ltd.     

Executive function and intelligence in the resolution of temporary syntactic ambiguity: an individual differences investigation

In the current study, we examined the role of intelligence and executive functions in the resolution of temporary syntactic ambiguity using an individual differences approach. Data were collected from 174 adolescents and adults who completed a battery of cognitive tests as well as a sentence comprehension task. The critical items for the comprehension task consisted of object/subject garden paths (e.g., While Anna dressed the baby that was small and cute played in the crib), and participants answered a comprehension question (e.g., Did Anna dress the baby?) following each one. Previous studies have shown that garden-path misinterpretations tend to persist into final interpretations. Results showed that both intelligence and processing speed interacted with ambiguity. Individuals with higher intelligence and faster processing were more likely to answer the comprehension questions correctly and, specifically, following ambiguous as opposed to unambiguous sentences. Inhibition produced a marginal effect, but the variance in inhibition was largely shared with intelligence. Conclusions focus on the role of individual differences in cognitive ability and their impact on syntactic ambiguity resolution.

The influence of lying positions and postural control on hand-mouth and hand-hand behaviors in 0-4-month-old infants

The purpose of this study was to verify how and when body position and postural control affect hand-mouth and hand-hand behaviors in infants during their first 4 months of life. Forty healthy infants were positioned in supine, prone and side-lying positions so that frequency and duration of the behaviors were quantified. Postural control when in supine and prone was also analyzed. The prone position elicited hand-mouth behavior in 0-2-month-old infants. The side-lying position elicited hand-mouth behavior in 3-4-month-old infants and hand-hand behavior in 2-4-month-olds. The increased postural control promoted the emergence of hand-hand behavior when in supine, and decreased hand-mouth behavior when in prone. The results show that self-exploratory behaviors may be affected not only by extrinsic constraints, represented by different body positions, but also by intrinsic constraints, represented by characteristic action possibilities and postural control of each age group.
