Working in Dyads and Alone: Examining Process Variables in Solving Insight Problems

This study investigated the effects of working in dyads and their associated gender composition on performance (solution rate and time) and process variables (number of impasses, number of passed solutions, and number of problem solving suggestions and interactions) in a set of classic insight problem solving tasks. Two types of insight problems were used: multiple moves available (MMA) and few moves available (FMA) problems. The results showed no effects on number of problems solved or solving time, but group and gender composition effects emerged when looking at process variables such as number of impasses, time to impasse, number of passed solutions, number of problem solving suggestions, and number of interactions between dyad members. Results support prior evidence that process loss in creative problem solving may be due to differences in interpersonal interactions during group problem solving that do not necessarily affect overall problem solving success.     

Are delusional contents replayed during dreams?

The relationship between dream content and waking life experiences remains difficult to decipher. However, some neurobiological findings suggest that dreaming can, at least in part, be considered epiphenomenal to ongoing memory consolidation processes in sleep. Both abnormalities in sleep architecture and impairment in memory consolidation mechanisms are thought to be involved in the development of psychosis. The objective of this study was to assess the continuity between delusional contents and dreams in acutely psychotic patients. Ten patients with a single fixed and recurring delusional content were asked to report their dreams during an acute psychotic break. Sixteen judges with four different levels of acquaintance to the specific content of the patients’ delusions were asked to group the dreams, expecting that fragments of the delusional thought would guide the task. A mathematical index (f, t) was developed in order to compare correct groupings between the four groups of judges. Most judges grouped the dreams slightly above chance level and no relevant differences could be found between the four groups [F(3, 12) = 1.297; p = n.s.]. Scoring of dreams for specific delusional themes suggested a continuity in terms of dream and waking mentation for two contents (Grandiosity and Religion). These findings seem to suggest that at least some delusional contents recur within patients’ dreams. Future studies will need to determine whether such continuity reflects ongoing consolidation processes that are relevant to current theories of delusion formation and stabilization.     

AIDS Group Psychotherapy

Abstract

Clinical data are presented from a day spent at a New Jersey high school severely impacted by the World Trade Center disaster. Dissociation, a sense of numbness, anger, and guilt about feelings induced by the tragedy are all common dynamics in adolescents responding to trauma. The developmental issues that adolescents are confronting are described and discussed in terms of the challenges they present to the healing process. An argument is made that using groups to aid in the long recovery process with our young people should be a top public health priority.     

Reflection-Impulsivity in Mexican Children: Cross-Cultural Relationships

Urban Mexican children aged 5 (n = 23) and 9 (n = 87) years were given the Matching Familiar Figures Test (MFFT). The results indicate that the MFFT was a valid test of cognitive style for Mexican children. The younger children's MFFT performance was characterized as fast and inaccurate in relation to the older children's performance, which was slower and more accurate. Cross-cultural comparisons of Mexican MFFT scores with normative data from America, Japan, and Israel indicated that Mexican children were relatively impulsive in cognitive style in relation to children of other cultures. Potential factors contributing to these cross-cultural differences are discussed here.     

Investigating the Role of Instructional Focus in Incidental Pattern Learning

The authors used a novel dual-component training procedure that combined a serial reaction time task and an artificial grammar learning task to investigate the role of instructional focus in incidental pattern learning. In Experiment 1, participants either memorized letter strings as a primary task and reacted to the stimuli locations as a secondary task or vice versa. In Experiment 2, participants were given the same dual-component stimuli but performed only one of the two training tasks. Instructional focus affected the amount of learning and the likelihood of acquiring explicit knowledge of the underlying pattern. However, the effect of instructional focus varied for the different types of stimuli. These results are discussed in terms of the role of focused attention in incidental learning.     

Learning Under Conditions of Action Information Feedback

Methodological and empirical issues in research on action information feedback (AIF) are discussed, with particular reference to the procedures and results of Annett (1970). Positioning responses practiced under conditions of AIF training are learned, though generally less well than under terminal IF conditions. Effects obtained as a result of AIF training may be subject to variations in movement extent required, gain and other transformations, frequency, temporal locus, and mode of augmentation, many aspects of which remain to be systematically studied.     

Googling in Fear: Measuring Moral Panic Using Internet Searches Before and After Obama’s 2008 Election

ABSTRACT

The rhetoric, rumor, and hostility that surrounded the election of Barack Obama in 2008 appeared to correspond with the notion of a “moral panic.” However, systematically measuring phenomena like moral panics, which are volatile and dispersed in nature, can be difficult. This paper utilizes Google search data combined with other sources to examine the reaction to the candidacy and initial election of Obama. Given the nature of this particular panic, we hypothesize that panic-induced searches will be greater in states with a larger presence of Evangelical Protestants and consumption of conservative media outlets. Results from a series of generalized least squares time-series and two-stage regression models demonstrate that searches related to “socialism” and the “Antichrist” grew significantly around Obama’s election, indicating Obama’s “folk devil” status and a growing moral panic. Additionally, the intensity of the panic appears to be moderated by religious cultures and media consumption. Implications for theory and future research are discussed.     

Inter-individual variability of forces and modular muscle coordination in cycling: A study on untrained subjects

The aim of this study was to investigate the muscle coordination underlying pedaling in untrained subjects by using the muscle synergies paradigm, and to connect it with the inter-individual variability of EMG patterns and applied forces. Nine subjects performed a pedaling exercise on a cycle-simulator. Applied forces were recorded by means of instrumented pedals able to measure two force components. EMG signals were recorded from eight muscles of the dominant leg, and Nonnegative Matrix Factorization was applied to extract muscle synergy vectors W and time-varying activation coefficients H. Inter-individual variability was assessed for EMG patterns, force profiles, and H. Four modules were sufficient to reconstruct the muscle activation repertoire for all the subjects (variance accounted for >90% for each muscle). These modules were found to be highly similar between subjects in terms of W (mean r = .89), while most of the variability in force profiles and EMG patterns was reflected, in the muscle synergy structure, in the variability of H. These four modules have a functional interpretation when related to force distribution along the pedaling cycle, and the structure of W is shared with that present in human walking, suggesting the existence of a modular motor control in humans.
