The how and why of disagreement among perceivers: An exploration of person models

Impression formation has been conceptualized as a process whereby perceivers form person models of others, describing what the person is like and why (Park, DeKay, & Kraus, 1994). If they exist, person models could help explain why there appears to be little consensus in personality judgments; perceivers forming different models of a person would also view them differently on trait and affect ratings. Two experiments were conducted to test assumptions of the person-model paradigm using naturalistic targets. The structure of person models was examined, along with their content. Results demonstrated that three distinct person models emerge for each target and that the majority of perceivers can easily identify with one of the three models. We found that person models were valid across different groups of perceivers, and that the models differed in terms of masculinity-femininity and affect. Implications for the person model formulation process are discussed.     

Stressed organizations and organizational stressors: A systemic analysis of workplace injury

The experiences of five injured workers from one workplace which had been identified as having a very poor workers' compensation claims experience were analyzed using a systemic theory framework. It was predicted that the fundamental stress-producing conflict between safety and profit that exists in industry between workers and their employers is exacerbated when a worker is injured; furthermore, the degree of stress experienced by both the injured worker and the employer is related to the impact of the injury on the organization and on the productivity of the workplace. The increased stress in both the injured worker and the employer results in increased rigidity in responding to the change or threat in the organization caused by workplace injury. A systemic approach to rehabilitation was recommended in which the employer as well as the injured worker were viewed as clients who required varying levels of support and intervention in managing workplace injury.     

Clinical Utility of Expanded Carrier Screening: Reproductive Behaviors of At-Risk Couples

Expanded carrier screening (ECS) analyzes dozens or hundreds of recessive genes to determine reproductive risk. Data on the clinical utility of screening conditions beyond professional guidelines are scarce. Individuals underwent ECS for up to 110 genes. Five-hundred thirty-seven at-risk couples (ARC), those in which both partners carry the same recessive disease, were invited to participate in a retrospective IRB-approved survey of their reproductive decision making after receiving ECS results. Sixty-four eligible ARC completed the survey. Of 45 respondents screened preconceptionally, 62% (n = 28) planned IVF with PGD or prenatal diagnosis (PNDx) in future pregnancies. Twenty-nine percent (n = 13) were not planning to alter reproductive decisions. The remaining 9% (n = 4) of responses were unclear. Of 19 pregnant respondents, 42% (n = 8) elected PNDx, 11% (n = 2) planned amniocentesis but miscarried, and 47% (n = 9) considered the condition insufficiently severe to warrant invasive testing. Of the 8 pregnancies that underwent PNDx, 5 were unaffected and 3 were affected. Two of 3 affected pregnancies were terminated. Disease severity was found to have significant association (p = 0.000145) with changes in decision making, whereas guideline status of diseases, controlled for severity, was not (p = 0.284). Most ARC altered reproductive planning, demonstrating the clinical utility of ECS. Severity of conditions factored into decision making.     

Conceptual Similarity and Communicative Need Shape Colexification: An Experimental Study

Colexification refers to the phenomenon of multiple meanings sharing one word in a language. Cross-linguistic lexification patterns have been shown to be largely predictable, as similar concepts are often colexified. We test a recent claim that, beyond this general tendency, communicative needs play an important role in shaping colexification patterns. We approach this question by means of a series of human experiments, using an artificial language communication game paradigm. Our results across four experiments match the previous cross-linguistic findings: all other things being equal, speakers do prefer to colexify similar concepts. However, we also find evidence supporting the communicative need hypothesis: when faced with a frequent need to distinguish similar pairs of meanings, speakadjust their colexification preferences to maintain communicative efficiency and avoid colexifying those similar meanings which need to be distinguished in communication. This research provides further evidence to support the argument that languages are shaped by the needs and preferences of their speakers.     

Selective reinforcement of schizophrenics' interview responses

In this experiment each of five examiners tested and interviewed four subjects in each of three conditions. The subjects were 60 male, hospitalized schizophrenics. The three conditions were the reinforcement, after an operant period, of “sick talk”, “healthy talk”, or plural nouns during a structured interview. Half the Welsh factor A and R scale items were administered before the interview, half after the interview. Significant differences were found among experimental conditions in terms of changes from operant to reinforced interview periods in percentage of “sick talk” emitted by subjects and changes from pre- to post-testing in terms of Welsh R scores. The correlation between these two measures of change was statistically significant. The results were discussed in terms of the different therapeutic strategies of neoanalytic and behaviour therapists.     

A social relations analysis of nonverbal communication accuracy in married couples

This paper presents a reanalysis of a study (Sabatelli, Buck, & Drever, 1982) that related nonverbal communication accuracy in married couples to marital complaints, using the social relations model developed by Kenny and his colleagues The social relations model allows for the analysis of the communication process in a new and more complete way where, for the first time, the relative contributions of sender, receiver, and unique relationship effects to overall nonverbal communication accuracy can be assessed In addition, each of these factors can be related to marital complaints and the patterns of communication within dyads can be examined for the presence of complementarity/similarity and reciprocity/compensation The overwhelming percentage of variance in communication accuracy was accounted for by sender and unique relationship effects while little variance in communication accuracy was accounted for bv receiver effects In addition, no evidence of complementarity/similarity and only weak support for reciprocity/compensation in the communication abilities of wife and husband was found With regard to marital complaints, the most striking result was the negative correlation between wives' sending ability and husbands' complaints, a finding consistent with the previous report In addition, and consistent with the former analysis, the wives' unique abilities to decode their husbands' expressions were found to correlate negatively with the wives' marital complaints     

Modifying an underlying component of perceived arm length: adaptation of tactile location induced by spatial discordance

In four experiments we examined the adaptation and aftereffect that resulted from a treatment yielding tactile/kinesthetic length discordance between the arms. Perceived discordance diminished with trials and tended to zero. Subsequent visual/tactile cross-modal judgments of distance showed the aftereffect to be a change in the perceived location of an unseen probed spot on each hand with respect to the location of a truly coincident visual marker. This occurred toward the body for the probed spot on one arm and away from the body on the other. There were three other main findings: (a) Arm movement was not a necessary condition for adaptation or aftereffect; (b) with intrinsic length information about the right arm present, but touch information from the right index finger absent during treatment, adaptation and aftereffect were abolished; (c) aftereffects of tactile location that were manifest at the hand and wrist tended to zero when a point close to the elbow was tested with a cross-modal procedure. The experiments provide evidence that the mapping of the tactile sheet onto an internal length domain had been modified by the treatment. The sensory consequences of the treatment led many subjects to report spontaneously that their arms felt to be of different lengths.
