A renewed look at Miller's conflict theory of aggression displacement.

The present study is the first to examine Miller's theoretical assumptions of displaced aggression using human subjects. Subjects in the present study either served as nonangered controls, were angered by the experimenter's confederate, or were both angered by and led to fear the confederate. All subjects were then able to three targets: the confederate, a person described as a friend of the confederate, and a person having no association with the confederate. Targets received the most intense aggression from angered subjects. The difference between the aggression gradients for high-anger-low-fear and control subject. Frightened subjects gave their most intense aggression to the displaced targets. Results also support the suggestion that direct aggression is most likely if the aggressor can first extinguish some of his fear by attacking more indirect targets.     

Image of God and Community Volunteering among Religious Adherents in the United States

Individual theological beliefs provide important motivations for religious people to volunteer in their communities. Compassion and loving one’s neighbor are both ideas that can motivate individuals to volunteer their time and talents. Religious believers who have conservative theological beliefs may see volunteering for their communities as a minor factor in their religious calling. Recent research on the role of social embeddedness within religious communities, however, has questioned the importance of theology as a motivation to volunteer (Putnam and Campbell, in American Grace. Simon and Schuster, New York, 2010; Lewis et al., in Soc Sci Res 42: 331–346, 2013). In this paper we test the effects of a religious adherent’s image of God’s disposition toward the world on their pattern of community volunteering. Using data from the 2005 Baylor Religion Survey and multinomial logit models, we find that having an image of God as judgmental lowers the odds that religious adherents report having volunteered for the community independent of their place of worship. Adherents who are most willing to engage the external community independent of a place of worship are those with less judgmental images of God. We also find that embeddedness is associated with volunteering for and with the place of worship in the community. Implications for theory, research and social capital formation are discussed.     

Working memory resources in young children with mathematical difficulties

Kyttälä, M., Aunio, P. & Hautamäki, J. (2010). Working memory resources in young children with mathematical difficulties. Scandinavian Journal of Psychology, 51 , 1–15.
Working memory (WM) ( Baddeley, 1986, 1997 ) is argued to be one of the most important cognitive resources underlying mathematical competence ( Geary, 2004 ). Research has established close links between WM deficits and mathematical difficulties. This study investigated the possible deficits in WM, language and fluid intelligence that seem to characterize 4- to 6-year-old children with poor early mathematical skills before formal mathematics education. Children with early mathematical difficulties showed poor performance in both verbal and visuospatial WM tasks as well as on language tests and a fluid intelligence test indicating a thoroughly lower cognitive base. Poor WM performance was not moderated by fluid intelligence, but the extent of WM deficits was related to language skills. The educational implications are discussed.     

Do Lemmas Speak German? A Verb Position Effect in German Structural Priming

Lexicalized theories of syntax often assume that verb‐structure regularities are mediated by lemmas, which abstract over variation in verb tense and aspect. German syntax seems to challenge this assumption, because verb position depends on tense and aspect. To examine how German speakers link these elements, a structural priming study was performed which varied syntactic structure, verb position (encoded by tense and aspect), and verb overlap. Abstract structural priming was found, both within and across verb position, but priming was larger when the verb position was the same between prime and target. Priming was boosted by verb overlap, but there was no interaction with verb position. The results can be explained by a lemma model where tense and aspect are linked to structural choices in German. Since the architecture of this lemma model is not consistent with results from English, a connectionist model was developed which could explain the cross‐linguistic variation in the production system. Together, these findings support the view that language learning plays an important role in determining the nature of structural priming in different languages.     

The role of neuropeptide Y in the amygdala on corticotropin-releasing factor receptor-mediated behavioral stress responses in the rat

Neuropeptide Y (NPY) is one of the most abundant peptides in the brain and has been shown to be a critical regulator of emotionality, most notably for its effect in decreasing anxiety-like behaviors. The stress response in both humans and animals has been shown to involve a cascade of biological events initiated by corticotropin releasing factor (CRF), another centrally acting peptide. Interestingly, NPY and CRF are present in similar brain regions mediating stress responses and may act in an opposing fashion. The basolateral nucleus of the amygdala (BLA) is a distinct division of the amygdala and contains CRF receptors and the highest concentration of NPY neurons. The current study investigates the behavioral effects in rodents when NPY is injected directly into the BLA prior to the pharmacological stressor, urocortin I (Ucn; a CRF receptor agonist) or the emotional stressor, restraint. The animals that underwent restraint were evaluated in the social interaction (SI) test, while those injected with Ucn into the BLA were assessed in the two floor choice test, a modified version of the conditioned-place avoidance paradigm. The results showed that injections of NPY into the BLA prior to Ucn significantly blocked the development of the avoidance behavior in the two floor choice test and the decrease in SI time that is usually seen following restraint stress. These results provide further support that an interaction between NPY and CRF within the BLA may be critical for maintaining a normal homeostatic emotional state.     

Judgmental God image,social embeddedness,and social trust among the highly religious in the United States

In this article we explore two propositions concerning the manner in which judgmental God image affects social trust among the highly religious in the United States. One proposition argues that having a judgmental God image and being highly embedded in a community of co-religionists can create low levels of social trust through social bonding and the formation of particularized trust. The other proposition maintains that embeddedness in a moral community of co-religionists helps to reinforce the idea that people are basically good and require love and forgiveness. This leads to higher levels of trust. We test an interaction between judgmental God image and social embeddedness with OLS analysis and data from the 2014 Baylor Religion Survey. We restrict the analysis to the highly religious, those who have no doubt about the existence of God and belong to a place of worship. We find that respondents with a judgmental God image who do not belong to a moral community with any or a few friends have the lowest levels of social trust. Those who have a judgmental God image but are highly embedded in a moral community with at least half of their friends have higher levels of social trust. Embeddedness negates the negative effects of judgmental God image on social trust. Implications for research are discussed in the conclusion.     

Tiger salamanders’ (<Emphasis Type="Italic">Ambystoma tigrinum</Emphasis>) response learning and usage of visual cues

We explored tiger salamanders’ (Ambystoma tigrinum) learning to execute a response within a maze as proximal visual cue conditions varied. In Experiment 1, salamanders learned to turn consistently in a T-maze for reinforcement before the maze was rotated. All learned the initial task and executed the trained turn during test, suggesting that they learned to demonstrate the reinforced response during training and continued to perform it during test. In a second experiment utilizing a similar procedure, two visual cues were placed consistently at the maze junction. Salamanders were reinforced for turning towards one cue. Cue placement was reversed during test. All learned the initial task, but executed the trained turn rather than turning towards the visual cue during test, evidencing response learning. In Experiment 3, we investigated whether a compound visual cue could control salamanders’ behaviour when it was the only cue predictive of reinforcement in a cross-maze by varying start position and cue placement. All learned to turn in the direction indicated by the compound visual cue, indicating that visual cues can come to control their behaviour. Following training, testing revealed that salamanders attended to stimuli foreground over background features. Overall, these results suggest that salamanders learn to execute responses over learning to use visual cues but can use visual cues if required. Our success with this paradigm offers the potential in future studies to explore salamanders’ cognition further, as well as to shed light on how features of the tiger salamanders’ life history (e.g. hibernation and metamorphosis) impact cognition.     

Domain‐Specificity of Creativity in Young Children: How Quantitative and Qualitative Data Support It

One of the most controversial issues in contemporary research of creativity, whether a person's creativity is domain‐specific or domain‐general, was investigated in the present study. This study is composed of two parts, Study 1 and Study 2. In study 1, the relationships among 109 children's creative performances in three domains, and the relationships between those children's general creative thinking skills and their creative performances in three domains have been examined. Study 2 examines how the domain‐specificity and ‐generality issue is addressed in individual children via case studies of three highly creative children, hoping to provide enriching and qualitative specification to the quantitative data of the present study. In both studies, children's performances in language, art, and math domains were respectively judged by three experts who rated children's creativity on story‐telling, collage making, and math word‐problem creating tasks. Children's general creative thinking skills were assessed by a battery of two divergent thinking tests, including the Wallach‐Kogan Creativity Test (Wallach & Kogan, 1965) and the Real World Divergent Thinking Test adapted from Okuda, Runco, and Berger (1991). The findings of this study support the position that creative ability in young children is rather (but not absolutely) domain‐specific.     

Transfer of memory retrieval cues in rats

Two experiments using rats were conducted to determine whether the retrieval of a memory could be brought under the control of new contextual cues that had not been present at the time of training. In Experiment 1, rats were trained in one context and then exposed to different contextual cues immediately, 60 min, or 120 min after training. When tested in the shifted context, rats that had been exposed shortly after training treated the shifted context as if it were the original context. The control that the previously neutral context had over retrieval disappeared with longer posttraining delays, suggesting the importance of an active memory representation during exposure. Experiment 2 replicated the basic finding and demonstrated that the transfer of retrieval cues was specific to the contextual cues present during exposure. These findings with rats are consistent with findings from infant research (see, e.g., Boller & Rovee-Collier, 1992) that have shown that a neutral context can come to serve as a retrieval cue for an episode experienced elsewhere.
