Positive and negative associations underlying ambivalent attitudes

In two studies, we compared the strength of positive and negative associations of ambivalent attitudes to those of nonambivalent attitudes. In Study 1, results from an implicit association task showed that, in contrast to nonambivalent attitudes, ambivalent attitudes were characterized by strong positive and negative associations. In Study 2 responses to ambivalent attitude objects were faster following a positive as well as following a negative prime, compared to a non-word prime, whereas for neutral attitude objects prime type did not influence response times. Results provide direct evidence for the assumption that both positive and negative associations of ambivalent attitudes are relatively strong. Implications for attitude strength and attitude structure are discussed.     

Seven psychosocial principles to explain terrorism

Research approaches leading to the understanding of the terrorist phenomenon are suggested. Seven principles explaining terrorism are analysed from a psychosocial approach: They could complete the explanations of terrorism focused in socio-structural and psychological variables, the latter being insufficient and often erroneous. Thus, terrorism is presented as a strategy of political influence, and the psychological attributes of terrorists are explained as the result of several influential social processes. We considered that terrorist attacks and campaigns correspond to strategic reasons, but we also assume that the rationality of the terrorists perspective is limited. As far as the organisational parameters are concerned, we propose an analogy with ordinary social movements, especially relating to their ideological frameworks of legitimisation and resource mobilization processes.     

Psychometric evaluation of the Brazelton Scale in a sample of Spanish newborns

This study analyses the data obtained from a sample of 220 healthy full-term neonates evaluated with the Neonatal Behavioral Assessment Scale, NBAS, 3rd edition. Standard scores were obtained for each of the 35 behavioral items and analysis of the main components of all the clusters was performed. Similarly to the original scale, the five following factors were obtained: Autonomic and Motor Systems, Habituation, State Organization, State Regulation, and Social Interactive. The analysis of the reliability of these groupings reveals that it is between moderate and high (the average Cronbach's alpha coefficient was .78).     

Central ghrelin increases anxiety in the Open Field test and impairs retention memory in a passive avoidance task in neonatal chicks

Ghrelin (Grh) is an endogenous ligand for the growth hormone secretagogue receptor. Although Ghr stimulates feeding in rats, it inhibits feeding in neonatal chicks. However, little is known about other central behavioral effects of Ghr. Therefore, we investigated the Ghr effects, injected intracerebroventricularly, on anxiety and memory retention of neonatal chicks in an Open Field test and in a one-trial passive avoidance task, respectively. In the Open Field test, the administration of Ghr in a dose-dependent manner increased the latency to ambulate but decreased ambulation activity, indicating an anxiogenic effect. Furthermore, chicks trained on a passive avoidance task and injected with a dose of 30 pmol of Ghr immediately after training showed an impairment of memory retention. However, there were no significant effects on the number of pecks during the pretraining, training, retention and discrimination. In addition, different doses of Ghr produced an inhibition in food intake at different times after injection. Our results indicate that Ghr induces anxiogenesis in chicks. Moreover, we have shown for the first time that Ghr can decrease memory retention in a non-mammalian species, suggesting that Ghr may play an important role in the processes of memory retention in birds.     

Associative theories of goal-directed behaviour: a case for animal–human translational models

Associative accounts of goal-directed action, developed in the fields of human ideomotor action and that of animal learning, can capture cognitive belief-desire psychology of human decision-making. Whereas outcome-response accounts can account for the fact that the thought of a goal can call to mind the action that has previously procured this goal, response-outcome accounts capture decision-making processes that start out with the consideration of possible response alternatives followed only in the second instance by evaluation of their consequences. We argue that while the outcome-response mechanism plays a crucial role in response priming effects, the response-outcome mechanism is particularly important for action selection on the basis of current needs and desires. We therefore develop an integrative account that encapsulates these two routes of action selection within the framework of the associative-cybernetic model. This model has the additional benefit of providing mechanisms for the incentive modulation of goal-directed action and for the development of behavioural autonomy, and therefore provides a promising account of the multi-faceted process of animal as well as human instrumental decision-making.

Suicide Exposure and Posttraumatic Stress Disorder: Is Marriage a Protective Factor for Veterans?

Alarming numbers of military veterans end their lives each day which has a profound effect on the military population. This study examines a sample (N?=?434) of suicide-exposed (i.e., personally knowing someone who has died by suicide) veterans to determine whether the proportion of individuals who report high impact from suicide exposure and those who have clinically-significant posttraumatic stress disorder symptoms is related to marital status. Using Hill’s (Social Casework 49: 139–150, 1958) ABC-X model for conceptualizing the relationships between variables, mean scores for posttraumatic stress disorder were significantly different between groups, and the odds of a married veteran reporting high-impact suicide exposure were 2.19 times lower than the odds of a single veteran reporting high-impact. Likewise, the odds of a veteran with high-impact suicide exposure having clinically-significant posttraumatic stress disorder symptoms were 10.04 times higher than veterans with low-impact suicide exposure. Findings indicate that veterans who are married are less likely to be highly-affected by another individual’s suicide. Thus, marriage is a protective factor for suicide-exposed veterans.     

I’ll Never Forgive You: High Conflict Divorce,Social Network,and Co-Parenting Conflicts

The relation between divorce, co-parenting conflicts, and children’s adjustment problems has been well established. An unresolved question for research and clinical interventions, however, is how conflicts between parents are maintained and/or escalate. This cross-sectional research tested the hypothesis that co-parenting conflicts in divorced couples are associated with perceived social network disapproval and that this relation is mediated by parents’ tendency to forgive each other. In Study 1, a convenience sample of 136 divorced parents recruited via online forums, we showed that perceived social network disapproval was indeed positively related to co-parenting conflicts and that parents’ tendency to forgive the other parent—albeit partly—explained this relationship. Strength of our research is that in Study 2, 110 parents referred to children’s mental health care because the wellbeing of the children was severely compromised by the severity of the conflicts between parents, we replicated these results. In both studies perceived social network disapproval and co-parenting conflicts were positively related and this link was mediated by forgiveness: perceived social network disapproval was negatively related to forgiveness, which in turn was negatively related to more parental conflicts.     

Childhood Cancer and Brain Tumor Late Effects: Relationships with Family Burden and Survivor Psychological Outcomes

This study examines illness-specific family burden as a mediator of the association between late effects of childhood cancer and survivors’ emotional and behavioral outcomes. Childhood cancer survivors (n?=?65; ages 10–17) two or more years off-treatment completed measures assessing internalizing and PTSD symptoms. Parents reported on illness-specific family burden, late effects severity, and survivor internalizing/externalizing problems. Providers documented the number of late effects. Illness-specific family burden was correlated with provider-reported late effects (r?=?.29, p?<?.05) and parent report of severe late effects (r?=?.56, p?<?.01). Results supported an indirect effect of illness-specific family burden on number of late effects and parent-reported survivor internalizing problems, p?<?.05. Indirect effects were not found in models predicting PTSD and externalizing problems. Illness-specific family burden is an important intervention target for reducing internalizing problems in childhood cancer survivors with late effects.     

论存在者与本质

本文首先从逻辑学与本体论的区分入手,强调了本质概念和存在概念的本体论或实存论性质,提出了一条区别于传统思辨哲学的从经验的存在者到先验的存在者的致思路线;尔后依次从质料与形式、本质与存在、主体与偶性三个层面阐述了阿奎那的本质特殊学说和实体（单纯实体和复合实体）学说;最后则强调了作为“第一存在”的“绝对单纯性”的上帝的本体论地位和形而上学意义。
