Response competition: a major source of interference in a tactile identification task.

Two experiments investigated the ability of subjects to identify a moving, tactile stimulus. In both experiments, the subjects were presented with a target to their left index fingerpad and a nontarget (also moving) to their left middle fingerpad. Subjects were instructed to attend only to the target location and to respond "1" if the stimulus moved either to the left or up the finger, and to respond "2" if the stimulus moved either right or down the finger. The results showed that accuracy was better and reaction times were faster when the target and nontarget moved in the same direction than when they moved in different directions. When the target and nontarget moved in different directions, accuracy was significantly better and reaction times were significantly faster when the two stimuli had the same assigned response than when they had different responses. The results provide support for the conclusion that movement information is processed across adjacent fingers to the level of incipient response activation, even when subjects attempt to focus their attention on one location on the skin.     

Negative triangles: simple geometric shapes convey emotional valence

It has been suggested that downward pointing triangles convey negative valence, perhaps because they mimic an underlying primitive feature present in negative facial expressions (Larson, Aronoff, and Stearns, 2007). Here, we test this proposition using a flanker interference paradigm in which participants indicated the valence of a central face target, presented between two adjacent distracters. Experiment 1 showed that, compared with face flankers, downward pointing triangles had little influence on responses to face targets. However, in Experiment 2, when attentional competition was increased between target and flankers, downward pointing triangles slowed responses to positively valenced face targets, and speeded them to negatively valenced targets, consistent with valence-based flanker compatibility effects. These findings provide converging evidence that simple geometric shapes may convey emotional valence.     

Post-event spontaneous intrusive recollections and strength of memory for emotional events in men and women

Spontaneous intrusive recollections (SIRs) follow traumatic events in clinical and non-clinical populations. To determine whether any relationship exists between SIRs and enhanced memory for emotional events, participants viewed emotional or neutral films, had their memory for the films tested two days later, and estimated the number of SIRs they experienced for each film. SIR frequency related positively to memory strength, an effect more pronounced in the emotional condition. These findings represent the first demonstration of a relationship between SIRs occurring after an emotional experience and subsequent memory strength for that experience. The results are consistent with the possibility that emotional arousal leads both to elevated SIR frequency and better memory, and that the covert rehearsal associated with SIRs enhances memory for emotional relative to neutral stimuli. Additional evidence of menstrual cycle influences on SIR incidence in female participants appears to merit consideration in future work.     

Thinking about the Needy, Justice, and International Organizations

This article has three main parts, Section 2 considers the nature and extent to which individuals who are well-off have a moral obligation to aid the world’s needy. Drawing on a pluralistic approach to morality, which includes consequentialist, virtue-based, and deontological elements, it is contended that most who are well-off should do much more than they do to aid the needy, and that they are open to serious moral criticism if they simply ignore the needy. Part one also focuses on the United States, and illustrates both how incredibly wealthy the U.S. is and some of the spending habits of its citizens; however, its considerations apply to the well-off generally. Section 3 considers whether justice provides reasons for helping the needy. Noting that justice in an extremely complex notion, it discusses numerous considerations relevant to justice’s scope and implications, including an extended Rawlsian conception of justice, an absolute conception, a comparative conception, the distinction between natural and social justice, and various elements of common-sense morality. Section 2 also distinguishes between agent-relative justice-based reasons, which are relevant to whether we act justly, and agent-neutral justice-based reasons, which are relevant to whether we have reasons of justicefor acting. Correspondingly, it argues that even if one can ignore the needy without acting unjustly, as philosophers like Robert Nozick and Jan Narveson contend, there may be powerful reasons of justicefor addressing their plight. Section 4 briefly address the responsibilities of international organizations like the World Bank, the International Monetary Fund (IMF), and World Trade Organization (WTO). Drawing on Section 2, it is suggested that in addition to standard reasons to act justlytowards needy members of the world’s community, there will be reasons of justicefor such organizations to aid the needy in both present, and future, generations. The article concludes by contending that the well-off in countries like the U.S. have reason to view international organizations like the World Bank, IMF, and WTO as their agents, and to seek to insure that they alleviate misfortunes amongst the world’s needy.     

Children’s reading skills: A comparison of traditional and computerized assessment

Student’s ability to read computer text was investigated by comparing reading performance on decoding and phonetics tests of the Woodcock-Johnson (Revised) Tests of Achievement, Forms A and B. Fifty-one students completed one form of the reading tests through the traditional administration method and a second form using computer administration. Initial form and administration order were counterbalanced. Coefficients of equivalence of .91 and .86 were obtained for traditional and computer administration methods of the two tests. The results are interpreted as indicating that computer-administered reading tests can assess the same domains as traditional measures, and that they may become increasingly important in the complete assessment of functional reading skills.     

Differential effects of emotional arousal in short- and long-term memory in healthy adults

Recent studies demonstrated important differences between short- and long-term memory mechanisms. Besides, the emotional component has a crucial role in memory formation. This study was carried out to answer whether there is a differential influence of emotional arousal in short- and long-term memory in healthy adults. Thirty-one healthy volunteers were divided into two major groups. In the first group long-term memory (LTM) was evaluated, with the testing session one week after training. The second group was tested 1h after training, where short-term memory (STM) was evaluated. Each group was divided in to two subgroups. One half of the volunteers was exposed to an emotionally neutral story, and the other half of each group was exposed to a closely matched but more emotionally arousing story. The testing session consisted of a questionary containing 80 questions of multiple choices. The results were evaluated through percentage of correct answers. Results showed that correct answers were increased, in LTM measures, in the subjects that were given the emotional version of the test. In STM measures, no differences were found between the emotional and neutral version. However, the presentation of emotional story caused an emotional reaction in both groups. The lack of effect of emotional arousal in STM suggests that amygdala is not related to STM mechanisms. Further studies using different approaches are needed to elucidate if STM processes are influenced by emotional arousal.     

Reflecting on Participatory,Action‐Oriented Research Methods in Community Psychology: Progress,Problems, and Paths Forward

This paper provides a critical reflection on participatory action research (PAR) methods as they pertain to community psychology. Following a brief review of the fundamental aspects of PAR, key developments in the field are examined. These developments include the redefinition of the research enterprise among groups such as Indigenous and consumer/survivor communities, challenges that attend the “project” framing of PAR, academic and practice context challenges, and important domains in which PAR methods need to become more engaged (e.g., social media and disenfranchised youth). Three illustrative case studies of programs of work in the areas of youth homelessness, consumer/survivor engagement, and Indigenous research are provided to illustrate these contemporary challenges and opportunities in the field. The authors make the argument that without an effort to reconsider and redefine PAR, moving away from the stereotypical PAR “project” frame, these methods will continue to be poorly represented and underutilized in community psychology.
