Determinants of diagnostic prototypicality judgments of the personality disorders

We evaluated the impact of three factors that have been suggested to be important determinants of the diagnostic process pertaining to personality disorders: (a) the number of features representative of a personality disorder category; (b) the extent to which those features are typical of the category, and (c) the dominance or proportion of category features to the total number of features. Thirty-two clinical psychologists evaluated 12 profiles of hypothetical patients in which these factors were varied factorially. The results revealed strong effects of typicality and dominance, but no effects for number. Implications for the assessment and classification of personality disorders are discussed.     

A room with a view and a polarizing cue: individual differences in the stimulus control of place navigation and passive latent learning in the water maze

We investigated individual differences in the stimulus control of navigational behavior in the water maze by comparing measures of place learning in one environment to measures of latent learning (via passive placement on the goal platform) in a novel environment. In the first experiment, 12 rats were trained to find a slightly submerged hidden platform at a fixed location in room A for 10 days (4 trials/day). Fast and slow place learners were identified by their mean escape latency and cumulative distance to the goal during acquisition. The same animals were then given a 2-min passive placement on the submerged platform in room B. Latent learning was assessed by the animal's escape latency on a single swim trial immediately following the placement in room B. The results showed that the good latent learners in room B were not necessarily the fast place learners in room A. This weak correlation may be related to the fact that some rats swam near the area in room B that corresponded to the former goal location in room A relative to a common polarizing cue (i.e., the door/entrance to both rooms). When the view of the door was blocked in a second experiment a significant positive correlation between place acquisition and the latent learning test was obtained, although escape performance following passive placement was not improved. These findings suggest that while place navigation and latent learning via passive placement may involve some common cognitive-spatial function, other associative (S-S and/or S-R) processes that occur during place navigation/active movement may be required for animals to exhibit truly accurate navigational behavior characteristic of asymptotic escape performance in the water maze. Additional implications for neurobiological studies using a procedural pretraining design are discussed.     

Small and negligible? Evidence on the Relation Between Individuals’ Power in the Job Situation and their Satisfaction with Life and Job

Experimental research suggests that high power and leadership result in the experience of more positive and less negative emotions. Extending these findings of experimental manipulations, we investigated relations between power and subjective well-being in a representative national survey. Defining power as the capability to administer resources or punishments, we inferred power from the number of people whom respondents supervise in their job. The results reflect a very small relation between this operationalization and individuals’ life and job satisfaction. The results suggest that prior experimental findings on the relation between power and satisfaction judgments cannot be applied directly to job situations.     

THE RATIONAL SOCIETY: A CRITICAL STUDY OF SANTAYANA'S SOCIAL THOUGHT,Beth J. Singer

Anthropocentric and individualistic foundations result in forest management policy based on linear, single‐dimensional, marginal analysis detrimental to the well‐being of the forest ecosystem. Recent theories from the fields of ethics, economics, and policy analysis find that nonlinear, multidimensional analysis is possible, provided one can divorce oneself from anthropocentric and individualistic tendencies. Deep policy is introduced as a policy perspective that encourages questioning the fundamental values upon which policy decisions are made, just as deep ecology encourages a similar questioning of ecological values. An experiment is proposed for forest management in the Pacific Northwest, in which a self‐realizing Forest Board demonstrates punctuated equilibrium in forest management policy.     

Psychological Determinants of Optimism Regarding Consequences of the War

Gazing behavior of 10 three-month-old twin infants (five male and five female) and their mothers during play, bottle feeding, and spoon feeding activities were analyzed. Video-tape equipment was used in the home; data were gathered as naturalistically as possible. Mothers looked at infants for a greater percentage of the total time and for longer durations than infants looked at mothers. A consistency-activation personality theory in which mothers are highly motivated to gaze at infants, but infants seek visual interest by looking away from mother, is suggested to interpret the findings. Both looking and not-looking gazes and mean and median measures of central tendency were shown to be helpful and necessary for the gazing analysis.     

The psychological conditions that predict work engagement among tertiary education employees

This study investigated the extent to which the psychological conditions and job characteristics predicted work engagement amongst higher education employees (n?=?149, females?=?60%) from a South African University. The participants completed a variety of instruments on psychological conditions of work, job characteristics and work engagement viz; the Work Engagement Scale (WES), Psychological Meaningfulness Scale (PMS), Job Enrichment Scale (JES), Work-Role Fit Scale (W-RFS), Co-Worker Relations Scale (C-WRS), Psychological Availability Scale (PAS), Self-Consciousness Scale (SCS), Job Resources Scale (JRS), Outside Activities Scale (OAS), Psychological Safety Scale (PSS), Supervisory Relations Scale (SRS) and the Co-Worker Norms Scale (CWNS). Data analysis applied multiple regression to predict work engagement from psychological meaningfulness, psychological availability and job characteristics and also to determine the mediation effect of psychological condition of availability on the relationship between work engagement and job characteristics (resources). Findings suggest psychological meaningfulness to predict work engagement and to mediate the relationship between job characteristics and work engagement. Psychological resources for work engagement should emphasise a sense of meaningfulness as a resource for work participation.
