A qualitative and serial analysis of social problem solving in aggressive boys

Social problem solving skills in 84 elementary school aged boys were assessed to identify those responses most salient in the prediction of ratings of aggressive and socially withdrawn behavior. Aggressive and socially withdrawn boys did not differ from the control group in the number of effective first solutions generated to the hypothetical stories. The control group generated significantly more effective solutions as second alternatives to the stories than did the aggressive or socially withdrawn boys. In addition, the number of effective second responses generated significantly predicted both aggression and social withdrawal after controlling for verbal problem solving. Results are discussed in terms of differences in cognitive processes as well as implications for treatment.This research was partially supported by a grant to the first author from the Charles Rieley Armington Foundation on Values in Children.

Spectral indices of cardiovascular adaptations to short-term simulated microgravity exposure

We investigated the effects of exposure to microgravity on the baseline autonomic balance in cardiovascular regulation using spectral analysis of cardiovascular variables measured during supine rest. Heart rate, arterial pressure, radial flow, thoracic fluid impedance and central venous pressure were recorded from nine volunteers before and after simulated microgravity, produced by 20 hours of 6° head down bedrest plus furosemide. Spectral powers increased after simulated microgravity in the low frequency region (centered at about 0.03 Hz) in arterial pressure, heart rate and radial flow, and decreased in the respiratory frequency region (centered at about 0.25 Hz) in heart rate. Reduced heart rate power in the respiratory frequency region indicates reduced parasympathetic influence on the heart. A concurrent increase in the low frequency power in arterial pressure, heart rate, and radial flow indicates increased sympathetic influence. These results suggest that the baseline autonomic balance in cardiovascular regulation is shifted towards increased sympathetic and decreased parasympathetic influence after exposure to short-term simulated microgravity.     

The paradox of Alypius and the pursuit of unwanted information

Prior work has found that people occasionally seek useless information, a violation of strict rationality. The present work examined whether and why curiosity can also cause individuals to seek predictably harmful information. In four studies, participants were given the opportunity to gain knowledge of questionable personal value. In each case, participants focused on their curiosity about the information and underweighted its consequences. As a result, participants tended to seek knowledge that they themselves believed they would be better off without. Consistent with Loewenstein’s [Loewenstein, G. (1996). Out of control: Visceral influences on behavior. Organizational Behavior and Human Decision Processes, 65, 272–292] analysis of visceral factors in decision making, these effects diminished with a time delay and when deciding whether to expose someone else to unpleasant information. These results shed light on a common yet paradoxical aspect of human behavior that presents a counterpoint to traditional hedonistic models of human motivation.     

Cognitive models of class structure and explanations of social outcomes

In this paper we argue that people's explanations of a wide range of social outcomes occur within a framework of expectations derived from beliefs about the pervasive influence of social class on individuals' life-chances. This claim is tested by examining the effect of varying the social class origins of vignette characters on judgments and explanations concerning their outcomes. Four domains of social activity are examined: occupational attainment, educational achievement, relationship success, and unemployment. In all of these areas, the class background of the characters was found to be associated with different outcome expectations, future expectations, judgments of responsibility and differences in the ways in which outcomes were explained. The results are consistent with the claim that people have cognitive models in which social class background is associated with particular social outcomes across a range of activities, and that these models are reasonably accurate representations of the relationships between social class and life-chances. This suggests that contrary to theories which have stressed the individualistic nature of belief systems in western societies, social class forms an important part of the popular representation of the influences on occupational, educational and relationship success.     

Cognitive factors in the explanation of the mismatch between confidence and competence in performing basic life support

Abstract

The main approach to rectifying the well documented poor basic life support (BLS) skills of doctors and nurses, based on a Skills Model, has met with only partial success. This study compares the utility of a Skills Model with one that incorporates a cognitive component in predicting BLS skills. Outcome-expectancy, self-efficacy, training and experience of BLS, and BLS ability were assessed in 53 trained nurses. Ability was unrelated to training or experience of BLS. Nurses who scored highest on the BLS skills assessment perceived the procedure as significantly more successful than those with lower scores. Self-efficacy was unrelated to ability, but was related to status: senior nurses were significantly more confident but no more competent in performing BLS than junior nurses. Nurses who had attended more arrests, while more confident, were no more competent than those who had attended fewer. Assessment of BLS skills reduced self-efficacy beliefs. A model for predicting the relationship between self-assessed ability and objectively assessed skill is outlined.     

Multiple points of entry into a circular enclosure prevent place learning despite normal vestibular orientation and cue arrays: evidence for map resetting

This study identified sources of map orientation critical for successful spatial problem solving by rats of a plus maze embedded in water. Disorientation slowed, but it did not prevent acquisition of goal location. Use of a circular enclosure with multiple points of entry prevented reliable goal location. A single entry point enabled the rats to locate a fixed goal. A cue array within the enclosure was ineffective in providing orientation. These data suggest that stable map orientation can be derived from entry location when enclosure geometry is uniformative, but is not readily taken from cue arrays. They further suggest that map orientation is reset when rats enter an enclosure.
