Influence of family of origin and adult romantic partners on romantic attachment security

According to attachment theory, attachment style derives from social experiences throughout the life span. The authors tested this expectation by examining associations between the quality of observed interaction patterns in the family of origin during adolescence and self-reported romantic attachment style and observed romantic relationship behaviors in adulthood (ages 25 and 27). Family and romantic relationship interactions were rated by trained observers from video recordings of structured conversation tasks. Attachment style was assessed with items from D. W. Griffin and K. Bartholomew's (1994a) Relationship Scales Questionnaire. Observational ratings of warmth and sensitivity in family interactions were positively related to similar behaviors by romantic partners and to attachment security. In addition, romantic interactions characterized by high warmth and low hostility at age 25 predicted greater attachment security at 27, after controlling for attachment security at age 25. However, attachment security at age 25 did not predict later romantic relationship interactions after controlling for earlier interactions. These findings underscore the importance of close relationships in the development of romantic attachment security but do not indicate that attachment security predicts the quality of interactions in romantic relationships.     

Ability and task constraint determinants of complex task performance

Previous research on basic information-processing tasks has suggested that there may be a dissociation between the underlying process determinants of task performance and associations with ability measures. This study investigates this dissociation in the context of a complex skill-learning task-an air traffic control simulation called TRACON. A battery of spatial, numerical, and perceptual speed ability tests were administered, along with extensive task practice. After practice, manipulations of task requirements and system consistency were introduced. Ability correlations with performance revealed a dissociation between some manipulations that have effects on performance means and the corresponding correlations with reference abilities. Implications for integrating experimental and differential approaches to explaining performance and possible avenues for improved selection measures are discussed.     

Violence risk assessment in persons with mental illness

Mental health clinicians are often asked to determine an individual's risk of future violence. Dangerous assessments are required in a wide variety of situations that include involuntary commitments, emergency psychiatric evaluations, seclusion and restraint release decisions, inpatient care discharges, probation/parole decisions, death penalty evaluations, domestic violence interventions, fitness for duty evaluations, and after a threat is made. This article provides an overview regarding the assessment of dangerousness in both adults and juveniles and a summary of recent research regarding the relationship of mental illness to violence.     

Playground Contexts for Aggression for Preschoolers with Hyperactivity

This study assessed the naturalistic conditions that set the occasion for aggressive behavior in three preschoolers with hyperactivity and aggression (H/A). Peer and teacher responses to preschoolers' aggression were also investigated. For a total of 114 aggressive instances observed, relatively low percentages of aggression in social play with at least one other child were documented. The antecedent condition that was most predictive of aggression was (a) when children were seeking to enter into an activity and were denied entry and (b) when another child interrupted an on-going activity. Aggression was about 14 times greater for seeking/interrupted activity than for ongoing social play. Finally, the percentage of negative responses from peers to aggression on the playground was almost three times the rate documented in past research for preschoolers without hyperactivity.     

Differential Conditioning Based on a Difference in the Predictability of Reinforcement

A Pavlovian procedure containing a set of several alternative reliable trial stimuli and a set of several alternative unreliable trial stimuli was used to determine if reliability of outcome, per se, would differentially condition additional trial stimuli that either preceded or followed those original trial stimuli in a serial conditioning paradigm. The reinforcing effectiveness of the antecedent stimuli themselves was later tested in a higher-order conditioning design. It was found that different rates could be established to the different antecedent stimuli in the absence of a difference in the probability of reinforcement. Further, stimuli paired with those antecedent stimuli in the higher-order conditioning test also exhibited a difference in rate. It was concluded that a combination of a stimulus that is always followed by food and another that is never followed by food are, in net, a more effective reinforcer than a common stimulus that has the same overall probability of reinforcement but which is followed by both outcomes.
