The impact of socially projected group composition on behavior in a commons dilemma: A self-attention perspective

Socially projected group compositions, based on subjects’ expectancies about the behavior of others and the number of subjects taking part on the resource use task, were indexed using Mullen’s Additive Other-Total Ratio (Mullen, 1987) and used to predict harvesting behavior in a commons dilemma. One-hundred forty-three males took part in a resource use task in groups ranging in size from two to six members. Just prior to harvesting trials, subjects indicated the number of those taking part that they expected to overharvest and to underharvest, and indicated to which of these groups they had assigned themselves. Results indicated that harvesting behavior varied as a function of the number of others expected to behave differently from self, and conformed to patterns predicted by Self-Attention Theory. With increases in the number of others expected to underharvest, indexing an increase in self-attention, subjects who indicated they would overharvest become more conservative in resource use. However, subjects who indicated they would underharvest did not significantly decrease harvest size with increases in the number of others expected to overharvest. These subjects were already harvesting at an optimal or sub-optimal rate, and therefore had no need to reduce the size of their harvests to match their behavior to standards stressing conservatism in resource use.     

Orthographic onsets and rimes as functional units of reading

Three experiments are described in which a partial identity priming procedure was used to investigate the hypothesis that orthographic onsets and rimes serve as units of visual word recognition. In Experiment 1, partial identity priming using word-final trigrams was observed only when the bigram corresponded to the orthographic rime unit. Nonrime primes were again ineffective primes. In Experiment 3, partial identity priming using word-initial bigrams was observed only when the bigram corresponded to the orthographic onset unit. Non-onset bigrams were ineffective primes. These differential priming outcomes cannot be explained by graphemic priming, prime frequency, or practice effects. They are consistent with the hypothesis that syllable onset and rime units serve as functional units of reading.     

A direct nomination method for the identification of neglected members in children's peer groups

This paper describes two studies that compared a direct nomination method for identifying the neglected members of children's peer groups with the commonly used derived social impact score method. In the first study, first-grade children were asked to nominate peers to a neglect dimension in addition to the traditional sociometric dimensions of like and dislike. Both neglect and social impact scores were quite stable over time. Social impact scores were significantly more stable than neglect scores when the full range of scores was considered; however, when the two measures were compared in terms of the stability with which children are identified as extreme scores, the two methods were equally reliable. In spite of this similarity, the two measures identified different children as extreme scorers on each occasion. In an attempt to explain this confusion, the second study investigated the patterns of correlations between observed behaviors and directly nominated neglect, like, and dislike scores and derived social preference and social impact scorers. Results indicated that directly nominated neglect scores were correlated with observed behavioral variables that are consistent with the notion of social neglect. Derived social impact scores were related to observed behavioral variables exactly as their component parts (directly nominated like and dislike scores) were related to these variables; thus, they carried little new information.     

Personal moral philosophies and moral choice

The moral choices and post-transgression reactions of individuals who adopted varying personal moral philosophies were examined in an experimental setting that permitted the manipulation of the salience of moral norms and the nature of the consequences of one's actions. As predicted, the two situational variables had a strong impact on moral action; only 50.0% of the subjects chose to violate a moral norm when that norm was salient and they would personally benefit by their actions; this percentage increased to 76.2% in the other conditions. Personal ethical philosophies also influenced moral choices and post-transgression reactions, for more of the idealistic subjects chose to act immorally relative to the low idealists (91.66% vs 70.83%), and subjects who were low in both idealism and relativism were less likely to transgress a moral norm if they personally would benefit. The results lend support to the proposed interpersonal model of morality, particularly as applied to post-transgression reactions.     

Knowledge organization and skill differences in computer programmers

Like experts in other fields, expert computer programmers can recall at a glance far more information relevant to their field than novices can. One explanation for this difference is that experts not only have more information, they have it better organized into meaningful chunks. In this paper, we infer the details of individual programmers' chunks of key programming concepts using the Reitman—Rueter (Cognitive Psychology, 1980, 12(4), 554–581.) technique for inferring tree structures from recall orders. Differences in organizations accompany skill-level differences. Beginner programmers' organizations show a rich variety of common-language associations to these programming concepts; Intermediate programmers show mixtures of programming and common-language associations; and Experts show remarkably similar, but not identical, organizations based clearly on programming knowledge.     

Sex Differences in Evaluations of Female and Male Victims' Responses to Assault

In an investigation of perceptions of victim response to assult, 84 female and 70 male subjects read a narrative in which either a female or a male victim was roughly assaulted by a male stranger. The victim was described as either offering no resistance, resisting in a verbally aggressive manner, or resisting in a physically aggressive manner. Results of 3 × 2 × 2 ANOVA's revealed that women and men expected different outcomes for aggressive victim resistance. Women anticipated a worse outcome than did men, especially for victims who resisted. Men expected the most favorable outcome for the victim when he or she fought with the assailant; women expected the most positive outcome with nonresistance, especially for female victims. Female victims were seen as much more likely than male victims to be raped by the assailant. Women rated rape as a more likely outcome for physically aggressive victims while men considered rape least likely when the victim fought back. Sex differences in evaluations of victim resistance are discussed in terms of identification and empathy with the victim, goals of the victim's response strategy, and the expected effectiveness of aggressive and nonaggressive reactions to attack.     

Organization revealed by recall orders and confirmed by pauses

The technique introduced here induces the organization of information in memory from systematic inspection of regularities in free recall. The form of the representation of this organization is an “ordered tree.” The technique has the advantage of being based on a theory of the way in which the data were generated and can be shown to produce a unique structure that captures all the kinds of regularities the theory of recall prescribes. Also presented is a collateral technique for measuring the amount of organization evidenced in a struture, as well as a procedure for identifying errors. The experimental work shows the technique's ability to recover the details of an organization presented to subjects and provides converging evidence for the particular structures induced from the pattern of recall pauses. In addition, the application of the technique to structures unknown a priori produced organizations that were easy to interpret and a second set of pauses that further confirmed the details of the induced structures.     

The effect of social cues on the eating behavior of obese and normal subjects1

Schachter's externality hypothesis suggests that overweight individuals are more likely to be induced to eat by salient external cues than normal weight individuals. While a range of studies have demonstrated the plausibility of this hypothesis in the case of sensory stimuli (e.g., taste cues), there is little evidence that the hypothesis applies to social stimuli. The current study examines this latter proposition by exposing male and female, overweight and normal weight subjects to a same-sex or opposite-sex peer model. Under the guise of engaging in a taste experiment, the subjects were either exposed to a model who tasted experiment, the subjects were either exposed to a model who tasted no crackers (no eat), one cracker (low eat), or twenty crackers (high eat). In addition, control model-absent conditions were also run for purposes of establishing baseline eating rates. If the externality hypotheses were to prevail in social domains, one would expect overweight subjects to be more prone to model the cracker-eating behavior of the peer than normal weight individuals. However, the findings indicate that all subject groups regardless of weight evidence a rather clear modeling effect and all subjects evidence social inhibition effects on their eating behavior as well. Several intriguing interactions among subject sex, model sex, subject weight, and social condition were also found. The discussion explores the relevance of an externality model of overweight eating in social domains, and focuses upon the interesting and somewhat distinct pattern of socially mediated eating exhibited by overweight females.
