A Developmental Meta-Analysis of Peer Conflict Resolution

A series of meta-analyses examine developmental trends in peer conflict resolution. Peer conflict resolutions are most likely to involve negotiation, with coercion and then disengagement the next most likely strategies. Patterns of conflict resolution differ with age. Coercion is common among children and disengagement is rare. Negotiation is prevalent among adolescents and young adults; the former do not differ in terms of coercion and disengagement, whereas the latter tend to avoid coercion in favor of disengagement. Conflict resolutions also vary as a function of peer relationships, assessment procedures, and reporters. Negotiation prevails in all peer relationships except those with siblings; there is more negotiation among romantic partners than among friends, and more negotiation among friends than among acquaintances. Negotiation is the overwhelming strategy of choice for those presented with hypothetical disputes, but actual conflicts tend to be resolved by coercion. Observers indicate that most conflicts involve coercive resolutions, in contrast to self-reports, which suggest that negotiation prevails. Although conclusions are qualified by the limited number of studies available, follow-up moderator analyses indicate that negotiation increases and coercion declines with age across most peer relationships, assessment procedures, and reporters such that different patterns of conflict resolution during childhood give way to the same relative ordering of strategies during young adulthood.     

Fits About Fit

The paper argues that two traditions have dominated research on person–environment fit, the individual differences tradition and the organisational psychology tradition. I briefly review these traditions using the present set of papers as exemplars of these traditions. Then the inclusion of national cultural issues in person–environment fit research, stimulated by two papers in this issue, is introduced and I suggest that this should be the start of a new tradition. Finally, I note that there has been little conceptualisation of, and research on, the environment in person–environment research. This is especially true with regard to the role of people in making environments, and environmental effectiveness outcomes for person–environment fit. I conclude with the thought that fits over fit are healthy because fit is usefully conceptualised and operationalised from so many different interesting perspectives.     

A Cross-National and Cross-Sectional Comparison of Men's Gender Role Conflict and Its Relationship to Social Intimacy and Self-Esteem

We hypothesized that men's nationality and age group would affect (a) their level of gender role conflict and (b) the strength of the relationship between gender role conflict and the psychological health variables of social intimacy and self-esteem. Three hundred twenty-five men (97 college-aged American, 86 middle-aged American, 82 college-aged Australian, and 60 middle-aged Australian) completed the Gender Role Conflict, Miller Social Intimacy, and Coopersmith Self-Esteem Scales. MANCOVA results revealed two significant interaction effects between (a) age group and social intimacy and (b) nationality and self-esteem. The discussion highlights a contextual interpretation of the results, limitations, and future research.     

Risk Factors for Suicidality Among Clients With Schizophrenia

Among clients with schizophrenia, suicidality is associated with extreme personal distress, an increased number of inpatient hospitalizations, increased health care expenditures, and early mortality. This study attempted to identify risk factors for current suicidality in clients diagnosed with schizophrenia (N = 223). Results indicated that severity of depressive symptoms most strongly correlated with degree of suicidality. Younger age and recent traumatic stress each significantly predicted suicidality independent of depressive symptoms. Stepwise regression procedures showed that the combination of depression, younger age, and traumatic stress might provide a general prediction model for suicidality among clients diagnosed with schizophrenia. Counseling implications of these findings are outlined.     

Evaluation of the psychometric properties of two forgiveness scales

This study examined the psychometric properties of two forgiveness scales using participants enrolled at a Midwestern Catholic university (N = 328). The Forgiveness Scale is a 15—item Likert-type scale designed to measure forgiveness toward an of-fender. The Forgiveness Likelihood Scale is a 10—item Likert-type scale designed to measure tendency to forgive across situations. Factor analyses revealed that the For-giveness Scale contains two subscales (i.e., Absence of Negative, Presence of Posi-tive) and the Forgiveness Likelihood Scale consists of a single factor. Both scales have adequate internal consistency and test-retest reliability. Both subscales of the Forgiveness Scale were significantly correlated in the expected direction with mea-sures of forgiveness, religiousness, anger, hope, religious well-being, existential well-being, and social desirability. The Forgiveness Likelihood Scale was significantly correlated in the expected direction with measures of forgiveness, religiousness, trait anger, religious well-being, and social desirability. The authors thank Sarah Danko, Anne Hovancsek, Carla Kmett, Jennifer Martin, and Colleen Ryan for their assistance. We kindly request that researchers who use the forgiveness scales evaluated in this study provide us with a summary of their psychometric data for the scales. The idea for creating the Forgiveness Likelihood Scale was based upon the Willingness to Forgive Scale (Hebl & Enright, 1993).     

How goals affect the organization and use of domain knowledge

Expert specialists organize their knowledge around information related to their goals. In the experiments presented here, the relation between goal use and knowledge organization was investigated by manipulating participants' goals as they learned about a novel domain. Experiment 1 showed that goal use produces biases toward goal-related information in categorization and induction. Experiment 2 revealed that the bias toward goal relatedness is not absolute; participants use their knowledge flexibly, depending on the context of induction. Experiment 3 showed that using information in the absence of a meaningful goal does not produce significant goal-related biases. Altogether, the effects of goal use are evident across a number of tasks and may depend on goal meaningfulness and the coherence it provides to goal-related knowledge structures.     

Visual working memory for global,object, and part-based information

We investigated visual working memory for novel objects and parts of novel objects. After a delay period, participants showed strikingly more accurate performance recognizing a single whole object than the parts of that object. This bias to remember whole objects, rather than parts, persisted even when the division between parts was clearly defined and the parts were disconnected from each other so that, in order to remember the single whole object, the participants needed to mentally combine the parts. In addition, the bias was confirmed when the parts were divided by color. These experiments indicated that holistic perceptual-grouping biases are automatically used to organize storage in visual working memory. In addition, our results suggested that the bias was impervious to top-down consciously directed control, because when task demands were manipulated through instruction and catch trials, the participants still recognized whole objects more quickly and more accurately than their parts. This bias persisted even when the whole objects were novel and the parts were familiar. We propose that visual working memory representations depend primarily on the global configural properties of whole objects, rather than part-based representations, even when the parts themselves can be clearly perceived as individual objects. This global configural bias beneficially reduces memory load on a capacity-limited system operating in a complex visual environment, because fewer distinct items must be remembered.     

A model of the neural mechanisms underlying multisensory integration in the superior colliculus

Much of the information about multisensory integration is derived from studies of the cat superior colliculus (SC), a midbrain structure involved in orientation behaviors. This integration is apparent in the enhanced responses of SC neurons to cross-modal stimuli, responses that exceed those to any of the modality-specific component stimuli. The simplest model of multisensory integration is one in which the SC neuron simply sums its various sensory inputs. However, a number of empirical findings reveal the inadequacy of such a model; for example, the finding that deactivation of cortico-collicular inputs eliminates the enhanced response to a cross-modal stimulus without eliminating responses to the modality-specific component stimuli. These and other empirical findings inform a computational model that accounts for all of the most fundamental aspects of SC multisensory integration. The model is presented in two forms: an algebraic form that conveys the essential insights, and a compartmental form that represents the neuronal computations in a more biologically realistic way.     

Systematic changes in the rate of instruction during driver training

Relatively little empirical evidence exists concerning variations in the quantity of instruction across learning in complex, real‐world tasks. Examination of driving instructors' remarks to pupils during actual lessons indicated the rate of comment declined in a coherent fashion across training, most consistent with a power function. The presence of a power law is reminiscent of learning functions found from studies in other skill domains when using indexes of performance, and suggests that quantity of instruction therefore might be used to assay the performance in complex tasks. The implications of these findings, for both basic and applied research, are discussed. Copyright © 2007 John Wiley & Sons, Ltd.     

Hoarding in obsessive-compulsive disorder: results from the OCD Collaborative Genetics Study

Hoarding behavior occurs frequently in obsessive-compulsive disorder (OCD). Results from previous studies suggest that individuals with OCD who have hoarding symptoms are clinically different than non-hoarders and may represent a distinct clinical group. In the present study, we compared 235 hoarding to 389 non-hoarding participants, all of whom had OCD, collected in the course of the OCD Collaborative Genetics Study. We found that, compared to non-hoarding individuals, hoarders were more likely to have symmetry obsessions and repeating, counting, and ordering compulsions; poorer insight; more severe illness; difficulty initiating or completing tasks; and indecision. Hoarders had a greater prevalence of social phobia and generalized anxiety disorder. Hoarders also had a greater prevalence of obsessive-compulsive and dependent personality disorders. Five personality traits were independently associated with hoarding: miserliness, preoccupation with details, difficulty making decisions, odd behavior or appearance, and magical thinking. Hoarding and indecision were more prevalent in the relatives of hoarding than of non-hoarding probands. Hoarding in relatives was associated with indecision in probands, independently of proband hoarding status. The findings suggest that hoarding behavior may help differentiate a distinct clinical subgroup of people with OCD and may aggregate in some OCD families. Indecision may be a risk factor for hoarding in these families.
